It has long been suspected that a small pāua (known as abalone, ormers or ear-shells overseas) found around a remote island chain north of Aotearoa New Zealand differs from all other pāua.

Our earlier genetic research, using pioneering methods to extract ancient DNA from shells, provided the extra evidence needed.

We could now formally name and describe the new species of pāua from the Three Kings Islands/Manawatāwhi.

The scientific name of the Manawatāwhi pāua, Haliotis pirimoana, was proposed by Ngāti Kuri, who hold historic and territorial rights over the islands (mana i te whenua). Its name means “the pāua that clings to the sea”.

Pāua live on shallow reefs around the world, where they graze on algae. Globally, there are about 70 pāua species, ranging from “button” to “beret” in size.

Globally, few wild-caught abalone fisheries remain due to overfishing and a “withering disease” that has, fortunately, not been detected in Aotearoa New Zealand.

In New Zealand, we now recognise four living pāua species. Three of these – the black-foot pāua (Haliotis iris, which grows to about 200mm in size), the yellow-foot pāua (H. australis, 120mm) and the virgin pāua (H. virginea, 70mm) – are distributed broadly along the coast of mainland New Zealand.

Pāua are a taonga (national treasure). Their opalescent shells are iconic: they form the eyes of carvings, were used in traditional fishing lures, and feature in contemporary art and jewellery.

Surprisingly, these wonderful colours are not caused by different pigments. Instead, they result from a layer of shell made of a special form of calcium carbonate that splits light into its component parts, like oil on water.

Recreational harvest of pāua as kaimoana (seafood) is a national pastime (as is debate over the best ways to tenderise and cook them). Black-foot pāua are also the focus of growing aquaculture and pearl industries.

Why this matters

It’s not every day we discover a new species, although it happens more often than you might think.

Species discovery is seldom punctuated by a clear “Eureka!” moment. More often, it’s a muted thought that something looks a little different. So it was with the discovery of the Manawatāwhi pāua.

The Manawatāwhi pāua grows to just shy of 40mm. It is unlikely to have any commercial value or require conservation efforts. However, this species is another in the list of taonga (treasures) unique to Manawatāwhi specifically, and to Aotearoa more broadly.

The Manawatāwhi island chain lies roughly 60km northwest of Cape Reinga/Te Rerenga Wairua, the northern tip of the North Island. The islands are rugged, remote and beautiful.

Surrounded by deep water, and directly in the path of the Tasman Front which brings warm water from Australia but results in the localised upwelling of cold water, Manawatāwhi teems with life. Many of the islands’ coastal and terrestrial species occur nowhere else on Earth.

Manawatāwhi is not “pristine”, but the region remains a benchmark showing what much of Aotearoa used to be like. Ngāti Kuri are keenly aware of the importance of the taonga in their rohe (tribal area), and they are active in restoration, research and conservation efforts.

Biodiversity research, expertise and reference collections are critical for understanding the structure of regional ecosystems and predicting how they might respond to human activities and the changing climate. Such research provides the evidence necessary for effective fisheries, biosecurity and conservation management. It can ultimately contribute significantly to the economy.

We are in a global biodiversity crisis. Species are going extinct faster than we can discover and name them. The Museum of New Zealand Te Papa Tongarewa and the National Institute of Water and Atmospheric Research (NIWA) recently partnered with Ocean Census to discover hundreds of new species from deep water off southern Aotearoa.

There are, however, thousands of species we have already discovered, which are still awaiting formal names. There are very few biodiversity scientists left in Aotearoa to do this work.

This research reflects our obligation towards future generations so they, too, can enjoy the wonderful richness of our biodiversity.

Australia needs tradies and materials to build the power grid of the future. So where are they?

As Australia’s electricity supply shifts to clean energy, a big challenge is looming. How do we “keep the lights on” as big coal plants close, and a far-flung network of wind and solar generators replaces them?

This balancing act was outlined in the latest annual stocktake by the Australian Energy Market Operator. It said large-scale renewables projects must be delivered on time and in full if electricity in Australia’s eastern mainland states, plus South Australia and Tasmania, was to remain stable in the next decade.

The energy transition doesn’t just mean building wind and solar generators. It also means getting electricity to where consumers need it, via the transmission network.

But Australia desperately needs the skilled workers and materials to build that infrastructure and keep the energy transition on track.

The transmission crunch

After electricity is generated by a coal plant or wind farm, it must be transported to an electrical substation. There, the electricity is converted to a lower voltage, then sent to homes and businesses.

Moving electricity from the generator to the substation requires high-voltage cables, towers to support them, and devices known as “transformers” to convert the energy. Collectively, this is known as the transmission network.

The clean energy transition is testing Australia’s transmission capabilities. Solar and wind farms are often built in regional areas, where it’s sunny and windy. In many cases, transmission infrastructure to those areas doesn’t exist, or needs upgrading.

The Albanese government’s A$20 billion Rewiring the Nation policy is an attempt to grapple with this problem. It aims to help finance the 10,000 kilometres of transmission lines the Australian Energy Market Operator has identified as needed.

But transmission lines are large, complex projects that take years to plan and build. Projects often suffer delays, both in Australia and around the world.

The International Energy Agency estimates 80 million kilometres of power lines must be built or refurbished globally by 2040 – and projects are not keeping pace.

Several factors can delay the rollout of the transmission network. Opposition from communities or landholders to hosting infrastructure is a well-publicised problem.

But two other hurdles are often overlooked: the equipment and workers needed for the massive expansion.

How to build an electricity grid

Building transmission lines involves:

  • civil works to install foundations and erect the towers

  • electrical works to string the lines between the towers with cranes or helicopters and connect to the grid

  • installing sub-stations and transformers.

Most materials are imported. Specialised components such as lines, transformers and cables are manufactured near bigger markets in Europe and the United States. Transmission towers are imported from overseas and assembled in Australia.

And workers are needed to put all the materials together. They include construction managers, electrical engineers, electricians, truck drivers, construction riggers and earthmoving operators.

The Australian Energy Market Operator now factors in a 12-month delay for transmission projects, based on recent precedent. It also notes many are scheduled for completion between 2025 and 2030.

This will create a spike in demand for equipment and workers.

The race for materials and workers

Around the world, transmission projects have been hit by delays in recent years. Specialised components must be ordered well in advance, increasing lead times for projects.

And Australia is a small buyer located a long way from manufacturers. Larger, established buyers are often prioritised, leaving Australia struggling to compete.

The workforce required for transmission projects is not especially large – peaking at around 4,000 workers in the late 2020s.

However, there is a shortage of specialised labour. Australia has been importing skilled transmission workers. But as transmission projects scale up globally, this labour pool may dry up.

As one project manager noted in a federal government report in 2021, the transmission industry is bracing for worker shortages if multiple projects proceed at the same time:

We don’t have enough substation specialists, commissioning specialists or linesworkers across Australia. […] It’s going to be tricky.

Some workers can be sourced from other industries. But they must be trained or upskilled, and tradespeople may not want to move to regional areas or become fly in-fly out (FIFO) workers. As a transmission builder noted in the report:

if someone has a choice between a FIFO or to live in Sydney or Brisbane and work on overhead rail then what do you choose – jumping on a plane and living in a camp to do a 12-hour day?

And what about electricians? Australia faces a shortage of sparkies as renewable energy projects scale up and homes move away from gas towards electrification. Jobs Skills Australia estimates the transition to a clean energy economy will require between 26,000 and 42,000 electricians out to 2030.

Smoothing the bumps

Securing the materials we need to build out the grid will be difficult.

Companies have begun “bundling up” orders for several transmission projects at once, to increase their buying power with overseas manufacturers. Proposals for local manufacturing of components exist, but these take time and could only reduce, not eliminate, our dependence on imports.

National coordination is needed to smooth the peaks in demand – for both materials and workers – created by many simultaneous transmission projects.

On the labour front, a huge training effort is needed, especially for engineers and key trades. Some initiatives are underway, but not at the scale required.

Unless governments and industry tackle these problems more seriously, Australia’s clean energy transition could face major delays.

When is a good time for a child to start music lessons?

Source: The Conversation (Au and NZ) – By Timothy McKenry, Professor of Music, Australian Catholic University

There are many reasons a child should learn a musical instrument. Not only does it give them the opportunity to make music, a significant body of research points to benefits for cognitive and academic achievement.

This is why a current New South Wales parliamentary inquiry has emphasised the importance of all children having the opportunity to learn music in primary school.

When it comes to starting lessons, research says “the sooner the better”. But pinpointing a precise age to start and particular learning approach depends on a range of factors.

How old is too old?

It is never too late to learn music. Recent research highlights the positive impacts of music lessons for people in residential aged care.

For children though, starting music lessons before nine offers a specific benefit parents should keep in mind. At around nine years of age musical aptitude or “talent” becomes a fixed trait. Before this age it is malleable and engaging in structured musical activity expands the possibilities of what a child can ultimately achieve through music.

Should my child call the shots?

There is debate among parents and teachers about whether parents should wait for their child to express interest in music lessons before starting.

Some children request lessons, particularly where they observe siblings and friends participating in music. Though asking is a good indication a child is ready, it is not necessary. Time is again a factor here.

A 1996 UK survey revealed enthusiasm for learning an instrument peaked at ages five to six. For children not already learning an instrument, the level of enthusiasm halved by age seven.

Which instrument?

Instruments including the piano, keyboard, violin, flute and recorder are ideal for an early start. The Suzuki Method (which believes musical ability can be developed) allows children to begin learning some of these at three. It’s common for teachers of any method to teach children these instruments from five and up.

String instruments are tailored to a child’s development with different sizes available. A child under five may begin learning with an instrument 1/32 the size of an adult instrument.

The ukulele has also become an increasingly popular “primer” instrument for children as young as four.

Brass and reed instruments (such as the trumpet or clarinet) require greater strength and losing baby teeth can make forming the right mouth shape or embouchure difficult. While children can start learning these instruments from the age of seven, it is not unusual for children to start brass and reed instruments in high school.

It’s common for a child to start on one instrument and change to another. This happens as a natural progression where a child begins on an inexpensive instrument such as recorder or ukulele and progresses onto the saxophone or guitar. Or a child might enjoy music, but dislike or become frustrated by their current instrument.

Which teacher?

In Australia, anyone can call themselves a music teacher, provided they have a working with children check and an ABN.

So parents need to exercise due diligence when selecting a teacher. Good teaching – particularly for younger children – requires more than simply the ability to play. Teachers should have a qualification, experience and ideally some kind of professional affiliation.

There are multiple evidence-based methods for teaching music. This includes Kodaly (which is based on singing and children’s stages of development) and Orff Schulwerk (which includes an emphasis on musical invention and improvisation).

Whatever their method, a good teacher will be able to articulate an age-appropriate learning method and explain how their approach changes as a child matures.

A good teacher will also be able to outline realistic strategies to help a child develop a sustainable practice routine. The amount of practice required depends on the instrument and the age of the child, but there should be clear expectations around practice.

There should also be clear expectations around the degree of parental involvement and intended learning milestones.

What if lessons aren’t an option?

Music lessons can be expensive and they can take up time in busy schedules. And we know many schools are under-resourced and cannot offer music education in classrooms.

Research suggests online lessons, streaming video tutorials and music learning apps, may be useful ways to expose children to music if they can’t learn in person.

Bold climate action benefits more than just the environment – it’s also great for business

Source: The Conversation (Au and NZ) – By Syed Shams, Associate Professor, University of Southern Queensland

As the world grapples with the intensifying challenges of climate change, businesses are under increasing pressure to take action.

To avert catastrophe, this will have to go beyond merely complying with new regulations and minimum standards. Business must lead the charge in good faith.

Yet still too often, taking bold action on climate is painted as a kind of tradeoff – that because it costs money to act, doing right by the environment comes at the cost of doing good business.

Our recent research calls this myth into question. We found improving carbon performance can go beyond addressing environmental concerns and provide tangible financial benefits.

Our study, spanning almost two decades of data from firms across the Asia-Pacific region, found that superior carbon management is linked to significantly lower financial risk.

That offers evidence taking action is no longer just an environmental imperative – it’s also an essential financial strategy.

It’s too hard to make business decisions in the face of climate uncertainty – here’s how ‘storylines’ could help


Lower risk in every category

The Asia-Pacific region is home to some of the world’s largest carbon emitters, including China, Japan and South Korea.

Businesses operating there face mounting pressure from regulators, investors and consumers to improve their environmental footprint.

Businesses around the world can no longer ignore the need for bold action on climate.

Our research examined more than 9,000 firm-year observations (such as annual reports) from 13 countries in the Asia-Pacific between 2002 and 2021. It sought to explore the relationship between carbon performance and three common types of business risk: idiosyncratic, systematic and total risk.

Idiosyncratic risks are those faced by a particular business, while systematic risks are those that affect the whole market, such as economic downturns. As you might expect, total risk combines these.




Read more:
The Crowdstrike outage showed that risk management is essential. Why are so many businesses reluctant to do it?


We found better corporate carbon performance was associated with lower levels of risk in all three categories.

Companies that took active steps to manage and reduce their carbon emissions enjoyed less volatility in their stock prices, diminished firm-specific risks, and weren’t as sensitive to market-wide economic shocks.

The reduction in total risk varied, ranging from 1.22% in Taiwan to as much as 4% in Australia.

These lower levels of risk reflect more than just that these firms are better at following the rules. There has been a seismic shift in how business’ behaviour is seen by the market and what we’ve come to expect.

It’s a kind of halo effect. Firms with better carbon credentials are seen as better positioned for market success more broadly – whether in dealing with regulatory changes, business disruptions or risks to their reputation. That can all make them more attractive to investors.

Stronger governance, stronger effect

Our study also found that in countries with higher quality corporate governance standards – which encompasses factors such as environmental regulations, effective law enforcement and anti-corruption measures – there was a stronger relationship between carbon performance and lower levels of risk.

Risk reductions were more pronounced in countries with strong governance frameworks, including Australia.
Taras Vyshnya/Shutterstock

What’s driving this effect? It’s most likely that in countries with strong governance frameworks, companies with solid environmental credentials are being rewarded with lower borrowing costs and greater market valuation.

That offers an important takeaway for policymakers.

It suggests that implementing measures like emissions trading schemes, standardised climate change performance metrics, and national commitments to international climate agreements can all enhance the financial benefits of carbon performance.

Creating such a business environment creates strong financial incentives for firms to take action and allows them to align their own carbon reduction efforts with national and global goals.

Unique challenges offer unique opportunities

Despite the clear benefits of improving carbon performance, there are some unique challenges for companies in the Asia-Pacific.

Emerging economies within this region, such as Indonesia, Thailand, and the Philippines, often have lower baseline levels of carbon performance compared to their more developed counterparts.

This is largely due to differences in how strict regulations are, what key government institutions are capable of, and lower levels of economic development. But these challenges are also opportunities.

For firms in these emerging markets, there’s an opportunity to proactively adopt global best practice, and position themselves as leaders in the transition to a low-carbon economy.

What can we learn?

Our research offers some important takeaways for investors, companies and the rest of us.

For investors, our research emphasises just how important companies’ environmental performance can be. Firms with poor carbon performance may face higher risks in general. That can mean higher returns are required to compensate investors for these risks.

On the other hand, firms taking meaningful steps to manage their carbon emissions are more likely to enjoy stable cash flows and lower volatility, which can boost investor confidence.

For companies, the message is clear. Investing in carbon management is not just an ethical or regulatory obligation — it is a sound financial decision.

By enhancing their performance on carbon, firms can lower their total risk levels, attract sustainability-focused investors, improve their access to capital markets, and lower their borrowing costs.

Strong action on climate doesn’t have to be a tradeoff. As the world rises to the challenge of living with climate change, the link between environmental accountability and financial performance will only grow stronger.

Narcolepsy is reduced to a punch line in pop culture. What does that mean for people who live with it?

Source: The Conversation (Au and NZ) – By Aaron Schokman, Research Fellow, Central Clinical School, Faculty of Medicine and Health, University of Sydney

What do you know about narcolepsy?

As a rare sleep disorder, you might not have heard much about it, or if you have, your perception may have been formed by the limited portrayals in media.

Several depictions of narcolepsy have been made over the years, from Deuce Bigalow (1999), to Rowan Atkinson in Rat Race (2001) and, more recently, on Prime’s series The Boys (2019–24).

But how well do these portrayals represent living with this rare sleep disorder?

More than just falling asleep

Narcolepsy is a neurological sleep disorder where the brain is unable to regulate the normal sleep-wake cycle. The condition affects roughly 1 in 5,000 people.

People living with narcolepsy feel extremely sleepy throughout the day and will often fall asleep in environments conducive for sleep (think sitting for prolonged periods). They also are unable to get restful sleep at night, often waking up multiple times a night and have abnormal sleep cycles.

In season four of The Boys we got to see what a superhero living with narcolepsy could look like, through Black Noir (Nathan Mitchell).

The Boys follows a group of “corrupt” superheroes who are both popular and politically influential, and a group of vigilantes that want to expose them for who they actually are. The show is a satirical critique of right-wing politics and America’s sway towards fascism, and trades heavily in shock value.

In season four, we learn one of these superheroes has narcolepsy. One of the characters notice Noir asleep during a superhero team meeting. When someone kicks Noir’s chair, he wakes and explains “Oh shit, sorry guys, I’m narcoleptic”.

While it is great that Black Noir puts narcolepsy in the spotlight, the portrayal somewhat trivialises what living with narcolepsy is like: sitting in a meeting room at 3 pm on a hot summer’s day is enough to make anyone feel sleepy, but narcolepsy is much more than that.

For anyone living with narcolepsy, sleepiness is always present and oppressive. To experience a similar level of sleepiness, the average person would need to stay awake for 48–72 hours.

In a preposterous turn, we also see Black Noir fall asleep in the middle of a fight scene. Suffice to say, the adrenaline and emotion from a fight would likely stave off falling asleep – but it might trigger one of narcolepsy’s defining symptoms, cataplexy.

True representations, and missed opportunities

Cataplexy is one of the symptoms of narcolepsy. Not everyone with narcolepsy experiences cataplexy, but those that do can briefly lose control of their muscles, and sometimes become completely paralysed for a few minutes after experiencing strong, usually positive emotion (yes, even during sex).

The 2019 movie Ode to Joy features Charlie (Martin Freeman), a man living with cataplexy. Charlie’s central turmoil in the film follows his journey navigating his desire to balance his condition (triggered by joy) and falling in love.

We get to see several examples of a cataplexy attack, though in some instances erring towards a cartoonesque portayal wherein Charlie becomes rigid as a plank and falls backwards. However, some scenes show instances that better approximate reality. We see Charlie looses control of his leg muscles and slowly collapse to the ground during intensely emotional moments.

Viewers with cataplexy might find the film validating or analogous to their own journey navigating relationships. But the film hyper-focuses on Charlie’s experience of cataplexy to the extent it ignores portraying the impact other symptoms has on his life. We don’t ever see Charlie feel sleepy or fall asleep, and narcolepsy is only ever mentioned once or twice even thought cataplexy only occurs in people with narcolepsy.

It is a great example of how pop culture and media portrayals of disorders can fail us. Rom-coms are a genre laden with formulaic tropes. Competing plot lines and limited screen time are perhaps not the best medium to fully convey a condition as complex and nuanced as narcolepsy. The audience could be left with the misinformed impression some people living with narcolepsy experience little to no sleep-related symptoms.

Inaccurate representation can be particularly harmful for individuals who have not yet been diagnosed, and perhaps contribute to the average delay in diagnosis of up to 15 years.

Stigma and functional impairment

In a 2015 episode of The Simpsons, Homer is diagnosed with narcolepsy.

The episode starts off with Homer asleep at work in the middle of an emergency, landing him in hospital. Marge is worried about how much Homer is sleeping throughout the day, sharing vacation photos of Homer constantly asleep with his doctor.

Surprisingly the episode accurately links Homer’s sleepiness to low levels of the brain neurotransmitter that controls the sleep wake cycle, accurate for many people with narcolepsy.

Perhaps unsurprisingly, Homer’s experience of narcolepsy is rather one-dimensional, with the episode focusing on the recurring gag of Homer using his diagnosis as an excuse to get out of performing undesirable tasks:

Dr. Hibbert: Narcolepsy’s merely sleeping sickness, and many narcoleptics do lead normal lives by avoiding stressful triggers like, uh, oh, let’s say…

Homer: Helping with the laundry?

Dr. Hibbert: Exactly.

While reductive, Homer’s portrayal of someone with narcolepsy plays into the common stigma that many people with narcolepsy face: laziness.

Narcolepsy necessitates frequent naps to stave off sleepiness and avoid falling asleep at inopportune moments or potentially unsafe situations. Yet western society often devalues sleep and often conflates the need to nap or sleep with laziness.

The misconception can often lead to feelings of internalised shame, affect help-seeking behaviours and lead to depression and anxiety.

Media and pop-culture are a key vehicle for spreading messages, building awareness, and shaping public opinion through representation. For the average person, popular media is the only representation they’ll be exposed to for narcolepsy and its symptoms.

For those living with the condition or are pre-diagnosis, mischaracterisations can result in stigma and contribute to the extended average delay in diagnosis.

Brazil just banned X. Could other countries follow suit?

Source: The Conversation (Au and NZ) – By Tariq Choucair, Postdoctoral Research Associate, Digital Media Research Centre, Queensland University of Technology

Authorities in Brazil, the country with the world’s fifth largest number of internet users, have banned the social media platform X (formerly known as Twitter).

The ban came into effect over the weekend. It followed a long-running battle between Elon Musk, the owner of X, and Brazil’s Supreme Court Justice Alexandre de Moraes who had previously ordered the social media platform to block far-right users.

The ban has outraged Musk. In the wake of it, he has claimed de Moraes is a “fake judge” and that the “the oppressive regime in Brazil is so afraid of the people learning the truth that they will bankrupt anyone who tries”.

Personal attacks aside, the ban shows Brazilian authorities are no longer willing to tolerate tech giants flouting the nation’s laws. Will other countries follow suit?

Why did Brazil ban X?

Brazil did not ban X out of the blue.

From 2020 to 2023, the Supreme Court in Brazil initiated three key criminal inquiries related to social media platforms.

The first inquiry investigated fraudulent news. The second investigated organised groups that manipulate discourse and engagement on digital platforms (known as “milícias digitais”). The third investigated individuals and groups involved in an attack on Brazil’s Congress in 2023, following the defeat of former president Jair Bolsonaro in the 2022 general election.

Then, in April this year, de Moraes ordered Musk to shut down several far right accounts which had spread misinformation and disinformation about Bolsonaro’s 2022 defeat.

This was not the first time X had received an order such as this.

For example, in January 2023, following the Congress attack, the Brazilian Supreme Court also ordered X and other social media platforms to block some accounts. Musk showed concern, but his platform ended up agreeing to the order.

However, this time Musk refused and subsequently removed X’s legal representative in Brazil. This was a significant development, as Brazilian law requires foreign companies to have legal representation in the country.

De Moraes gave Musk a deadline to appoint a new representative. The tech billionaire did not meet it, which was what triggered the ban of X.

Simultaneously, de Moraes also blocked the financial accounts of Musk’s internet satellite service, Starlink.

The ban on X will continue until Musk complies with all related court orders, including nominating a legal representative in Brazil and paying fines amounting to A$4.85 million.

What will happen now in Brazil?

Before the ban, there were nearly 22 million X users in Brazil.

Anyone who tries to use software to access the platform now faces fines of up to A$13,000 per day.

Since the ban, many former X users have migrated to other social media platforms. For example, more than 500,000 people joined the microblogging platform Bluesky, which said Brazil was now setting “all-time-highs” for activity.

The ban is part of a broader fight against social media platforms operating in Brazil. De Moraes has been a leader in this fight. For example, in an interview earlier this year, he said

The Brazilian people know that freedom of speech is not freedom of aggression. They know that the freedom of speech is not the freedom to spread hate, racism, misogyny and homophobia.

But far-right groups and Bolsonaro supporters disagree. They have been very vocal in their opposition to the ban – and the supreme court more generally. It is likely the ban will inflame existing social tensions.

In line with Brazilian law, other supreme court judges are now assessing the ban. They may decide to uphold the ban, but overturn the financial penalties for people in the country trying to access X. It’s also possible the other judges will overturn the ban itself.

Will other countries follow suit?

In social media posts since the ban, Musk has claimed other countries, including the United States, will follow Brazil and ban his social media platform.

There is no evidence to support this claim, and the ban in Brazil doesn’t apply anywhere else in the world.

However, it does add to a growing mood internationally that giant social media companies can be restricted and are not above national laws or any other power.

For example, last week French police arrested Pavel Durov, the founder of Telegram, for facilitating crimes committed on the direct messaging platform.

Other countries with an interest in tightening regulation of social media platforms, such as Australia, will surely be closely watching how both of these cases unfold.

View from The Hill: Australians don’t need to be told high interest rates are ‘smashing’ the economy, but is there an alternative?

Source: The Conversation (Au and NZ) – By Michelle Grattan, Professorial Fellow, University of Canberra

Treasurer Jim Chalmers mightn’t have expected his weekend comment – made ahead of expected low growth figures later this week – that interest rate rises were “smashing” the Australian economy to set off the reaction it has. After all, it’s been something of a Chalmers mantra.

In June he said rate rises were “hammering the economy”. On another occasion that month he said higher rates were “hammering consumption”. At the start of July, he said discretionary spending had been “absolutely hammered by higher interest rates”.

“The Treasurer’s comments were nothing new,” Prime Minister Anthony Albanese said, fending off questions at a Monday Perth news conference.

But new or not, the comment is touching an extremely sensitive, exposed nerve, again highlighting the divergent positions of the Reserve Bank and the government.

The bank is determined that inflation, which was an annual 3.8% in the June quarter (3.5% for the month of July), must be brought down to the target range of 2–3% as soon as practicable while also preserving employment. For the government, reducing inflation is a high priority but it is increasingly worried about an economy that’s crawling along the ground.

Chalmers tries to step carefully to avoid directly criticising the bank, but the differences are obvious, and his message is being sent through a loudhailer.

On Monday he doubled down on his “smashing” assessment, while “cherishing” the independence of the Reserve Bank. “We’ve got different responsibilities. Where our interests align and where our objectives align is on getting on top of this inflation challenge in our economy which doesn’t smash people who are already doing it tough enough,” he said.

“I think it’s self-evident the interest rate rises already in the system are putting people under pressure and slowing our economy. And I think the Australian people, frankly, expect me to tell it like it is.”

The sluggishness of the economy is set to be starkly obvious when the latest GDP figures are released on Wednesday.

Forecasters are predicting growth for the June quarter of 0.1 or 0.2 of a percentage point. That’s bad enough – if the figure were negative, the government would fall into a serious panic.

Recent indications from the US Federal Reserve that American rates are set to fall imminently in normal circumstances would raise hopes Australian rates would soon follow.

But Reserve Bank deputy governor Andrew Hauser dashed that prospect when he spoke to The Conversation’s podcast last week.

Just returned from a meeting of central bankers in the United States, Hauser flagged that at this stage the Reserve Bank was not shifting from governor Michele Bullock’s indication that, based on present knowledge, the bank would not be dropping rates any time soon. Indeed, at its last meeting the Reserve even discussed raising rates.

“Sadly, at the moment Australian inflation is a bit stickier than it has been in the US,” Hauser said. “We’re not yet as confident, as [Fed head Jay Powell] is in the US, that inflation in Australia is back on a sustainable path, back to target. And therefore we have to hold rates where they are for the time being.”

While cost of living, a witches’ brew of inflation and interest rates, and other issues see Labor now 50:50 with the Coalition on a two-party basis in this week’s Newspoll, the figures show the public has little faith inflation would be better if there were a Dutton government.

People were asked whether inflation would be higher, lower or the same if Peter Dutton and the Coalition were in power rather than the Albanese government. Only 24% said it would be lower; 41% said it would be the same and 18% thought it would be higher.

For most voters, there seems to be nowhere to turn to get out of the present economic impasse.

Is still water better for you than sparkling water?

Source: The Conversation (Au and NZ) – By Christian Moro, Associate Professor of Science & Medicine, Bond University

Still or sparkling? It’s a question you’ll commonly hear in a café or restaurant and you probably have a preference. But is there any difference for your health?

If you love the fizz, here’s why you don’t have to pass on the sparkling water.

What makes my water sparkle?

This article specifically focuses on comparing still filtered water to carbonated filtered water (called “sparkling water” or “unflavoured seltzer”). Soda water, mineral water, tonic water and flavoured water are similar, but not the same product.

The bubbles in sparkling water are created by adding carbon dioxide to filtered water. It reacts to produce carbonic acid, which makes sparkling water more acidic (a pH of about 3.5) than still (closer to neutral, with a pH around 6.5-8.5).

Which drink is healthiest?

Water is the best way to hydrate our bodies. Research shows when it comes to hydration, still and sparkling water are equally effective.

Some people believe water is healthier when it comes from a sealed bottle. But in Australia, tap water is monitored very carefully. Unlike bottled water, it also has the added benefit of fluoride, which can help protect young children against tooth decay and cavities.

Sparkling or still water is always better than artificially sweetened flavoured drinks or juices.

Isn’t soda water bad for my teeth and bones?

There’s no evidence sparkling water damages your bones. While drinking a lot of soft drinks is linked to increased fractures, this is largely due to their association with higher rates of obesity.

Sparkling water is more acidic than still water, and acidity can soften the teeth’s enamel. Usually this is not something to be too worried about, unless it is mixed with sugar or citrus, which has much higher levels of acidity and can harm teeth.

However, if you grind your teeth often, the softening could enhance the damage it causes. If you’re undertaking a home whitening process, sparkling water might discolour your teeth.

In most other cases, it would take a lot of sparkling water to pass by the teeth, for a long period of time, to cause any noticeable damage.

How does drinking water affect digestion?

There is a misconception drinking water (of any kind) with a meal is bad for digestion.

While theoretically water could dilute stomach acid (which breaks down food), the practice of drinking it doesn’t appear to have any negative effect. Your digestive system simply adapts to the consistency of the meal.

Some people do find that carbonated beverages cause some stomach upset. This is due to the build-up of gases, which can cause bloating, cramping and discomfort. For people with an overactive bladder, the acidity might also aggravate the urinary system.

Interestingly, the fizzy “buzz” you feel in your mouth from sparkling water fades the more you drink it.

Is cold water harder to digest?

You’ve chosen still or sparkling water. What about its temperature?

There are surprisingly few studies about the effect of drinking cold water compared to room temperature. There is some evidence colder water (at two degrees Celsius) might inhibit gastric contractions and slow down digestion. Ice water may constrict blood vessels and cause cramping.

However other research suggests drinking cold water might temporarily boost metabolism, as the body needs to expend energy to warm it up to body temperature. This effect is minimal and unlikely to lead to significant weight loss.

Which water wins?

The bottom line is water is essential, hydrates us and has countless other health benefits. Water, with carbonated bubbles or without, will always be the healthiest drink to choose.

And if you’re concerned about any impact to teeth enamel, one trick is to follow sparkling water with a glass of still. This helps rinse the teeth and return your mouth’s acidity back to normal.

Worried about your trees after the windstorms? Here are 7 signs you might be at risk

Source: The Conversation (Au and NZ) – By Gregory Moore, Senior Research Associate, School of Ecosystem and Forest Sciences, The University of Melbourne

Winter has ended dramatically across Australia’s southern states, as fierce winds and storms usher in spring.

Over the weekend, intense winds from a powerful cold front brought down trees, damaged powerlines, brought flooding rains and caused power outages for thousands of people. Gusts nearing 200 kilometres per hour were recorded in Tasmania. In southern New South Wales, a woman died after a tree fell on her holiday park cabin.

As southerners inspect the damage today, many of us will be looking anxiously at the trees we live next to – and wondering if they, too, could fall.

The good news is there are things you can do to make sure the trees near you are still safe.

These tips aren’t just for windstorm safety. As the climate changes, tree dieback is becoming more common. This year, we’ve seen large-scale dieback in south-west Western Australia and Tasmania. It’s increasingly important to keep tabs on large trees near you.

#1: Look down

When a whole tree falls over and pulls out its roots, it’s known as whole tree failure or “windthrow”. If this happens, it can be a major threat to you or your house.

There are often warning signs a tree might topple over even before a storm hits. On a windy day, look at the tree you’re worried about. Is there any sign of movement at the base of the tree and its visible roots? If so, call an arborist to come as quickly as possible to assess the risk.

#2. Look up

If large, dead branches are attached to the trunk, that’s dangerous. These branches – “hangers” – can be blown loose and be carried surprisingly far from the tree in strong winds. They’re also more likely to break during storms and strong winds than healthy branches.

To reduce your risk, it’s important to have these dead branches removed. The bigger the dead branch, the higher the risk. But small dead branches in a canopy are normal. These pose much less threat and can usually be left there.

#3. Inspect the junctions

Not all limb attachments are healthy or strong. If the place where the limb is attached looks damaged, it could mean the junction is weak and could fail. To check, look for signs of damage – loose bark, resin or sap on the bark or branch, or bark which has become much darker than usual.

Some junctions are riskier than others. Trunks and branches with steep V-shape junctions, or with fallen bark built up between them, are more likely to break during storms.

When do you call in the arborists?

#4. Look for changes in leaf colour and coverage

If your tree rapidly loses foliage colour or suffers dieback of branches and canopy, this can also be a warning sign. These changes show us the tree is stressed and its health is getting worse. Sick trees are more vulnerable to storm damage.

Look for yellow and brown leaves, dead shoot tips and large branch dieback from their tips and dead patches on large limbs.

#5. Check the roots

Let’s say an excavator accidentally cuts one of your tree’s major structural roots with a diameter 100 mm or bigger. If this happens, it could risk the entire tree. Roots can also be damaged if the soil around them become compacted or waterlogged. These situations can weaken a tree from below.

To spot these issues, look for evidence of trenches where workers have cut through roots. Even when covered over, trenches will usually seem lower than the surrounding soil. Look for where soil has been compacted by vehicles or regular foot traffic. For waterlogging, look to see if water pools around trunks and under trees.

Root damage can be harder to spot, but damage underground can also trigger branch breakage or whole tree failure.

#6. Double check your lopped trees

If your tree has been badly pruned or lopped, it can become a threat. Poor work can trigger the growth of poorly attached shoots around the cuts or branch stubs. These shoots are more likely to fall during strong winds.

When the shoots are small, they don’t matter. But they can grow very quickly. Once more than 150 mm in diameter or ten metres long, they pose real risks.

Look for branching shoots which look different. Their branch attachment may look strange, or there may be multiple shoots from the same place on the trunk or stem. These shoots often grow almost vertically and grow at a much faster rate than normal branches.

#7. Check your canopy

If a large old trees dies or falls over, it can leave a large gap that changes local wind speed and intensity.

When trees are removed along roads, tracks and from around properties, canopy cover falls and wind speeds generally increase. This can be a real problem for your other trees, as they’re now enduring stronger winds than they were used to. It’s sensible to monitor your remaining trees in these circumstances.

Stormy future

Intense winds are projected to arrive more often in many parts of Australia as the climate keeps changing. This, in turn, will affect the trees we live close to.

It’s becoming more common to see householders pushing to remove large trees to reduce risk. But this comes with new challenges. With big trees gone, the wind speed near you will increase.

Big trees also offer unmatched cooling in summer. And while tree horror stories make the news, the vast majority of trees remain safely anchored in the ground during intense storms.

It’s entirely understandable to get anxious about big trees near your home. But rather than reaching for the chainsaw, it’s worth booking in regular tree inspections by a qualified arborist every three to five years to give reassurance or take action to reduce the risk.

After working for the RBA for 30 years, here’s how I’d make it more accountable

Source: The Conversation (Au and NZ) – By John Simon, Adjunct Fellow in Economics, Macquarie University, Macquarie University

How can we tell if the Reserve Bank of Australia – which sets the interest rates that shape our national and household budgets – is doing a good job?

That’s partly what the Albanese government set out to test in setting up a review of the bank in 2022.

When that review reported back last year, many people were surprised it devoted so much of its attention to governance and culture, rather than things such as its inflation target, which helps the bank set interest rates.

The review recommended a more open decision-making process and an interest rate board made up of experts, something the parliament is yet to agree on.

However, for people such as myself who have worked at the bank (I was there for more than 30 years), that focus was exactly the right one.

To boost Australians’ trust in an institution that’s central to all our lives it is important to pass the legislation and implement the recommendations of the review.

In the meantime, there is more we can do: we can expect the bank be more transparent with all of us about what its plan is. This is not just the outcome it is aiming for, but how its decisions will get us there.

Bad luck vs bad forecasts

So how can we test the Reserve Bank’s performance? One way would be to see whether inflation is in its target band.

But there are all sorts of reasons why inflation might be out of the band that have nothing to do with whether the bank is doing its job. It might be out of the target band because of bad luck or because of things outside of the bank’s control.

Another method might be to look at the reasons inflation is not in the target band.

But this isn’t as useful as it sounds. If, for instance, inflation was outside of the target band because government spending was higher than the bank anticipated in the lead-up to an election, it could be argued it was the bank’s job to be better at anticipating and to set monetary policy accordingly.

It would certainly help for the bank to set out clearly the assumptions behind its forecasts and the reasons it made those assumptions at the time it makes its forecasts. But even then it would be hard to tell bad luck from bad forecasts.

Politics with Michelle Grattan: Reserve Bank’s Andrew Hauser says don’t read too much for Australia from US rates message


As it happens, the bank regularly publishes an account of the reasons why its forecasts have missed their marks. But the accounts generally tell us more about how the forecasts were wrong than why.

The account might, for instance, tell us services inflation was higher than forecast because productivity was lower than forecast and population growth was higher than forecast. But it won’t tell us much about whether the forecasts were reasonable in the first place.

Early last month, the bank’s deputy governor Andrew Hauser went further and seemed to argue the economy is subject to so much radical uncertainty that forecasting is itself a fool’s errand.

In such an environment, looking at what happened in the past won’t provide much of a guide to what will happen in the future.

Now I happen to think the argument that the economy is as hard to predict as what Elon Musk will do next – as Hauser argued in a speech this month – is wrong.

I think you can learn about the future by studying the past. Hauser himself devoted much of his speech to learning from the past.

Spell out responses in advance

But Hauser and the bank make an important point: forecasting the economy is difficult, and it is unfair to hold forecasters to outcomes.

There is an alternative: hold the bank to inputs.

Bruce Preston at The University of NSW has proposed requiring the bank to state ahead of time, with sufficient specificity to be verifiable, what it will do in certain circumstances.

We could then discuss whether its plan is reasonable ahead of time, and verify whether it did what it said it would do when those circumstances came about.

This would not require a slavish adherence to a rigid path for interest rates. But it would require a clearly articulated strategy, with responses to various eventualities set out ahead of time.

As an example, the bank might say ahead of time that

if inflation is no longer expected to be below 3% by mid-2025, we will raise rates.

Or it might say

if unemployment rises above a certain point, we will lower rates.

Unfortunately, the bank has recently been reluctant to give such “forward guidance”, other than saying its decisions will be “data dependent”.

Partly this has been because of a concern that any such guidance would be taken as a promise about what it will do to interest rates.

But there’s a difference between articulating a clear strategy and saying what will happen to rates. The bank might be wanting to give itself wriggle room.

In any event, if the bank did articulate clear strategies, it wouldn’t completely solve the problem. There would still be lots of ambiguity about what the circumstances were and how to apply the clearly set out strategies.

So what should be done?

Processes are what matters

Standard procedure in the world of auditing is to focus on the processes used to arrive at decisions, and it happens to be the focus of the Reserve Bank review.

In essence, the review found the processes the bank followed were insufficient to guarantee it was doing a good job.

It recommended

  • setting up an expert monetary policy board and appointing members through a transparent selection process

  • making the culture of the bank less insular, more welcoming of challenges and more engaged with research

  • establishing a specialist governance board with an external chair to drive higher standards of performance across the organisation

That’s why it is vitally important for the legislation putting those findings into effect to make it into law.

Treasurer Jim Chalmers intended the two boards to start work in July. The treasury called for expressions of interest in March.

Chalmers says agreement with his opposite number Angus Taylor is close.

While it is true that we will never be able to tell whether the bank is doing a good job by looking only at outcomes, we can make its processes more trustworthy and verifiable. The legislation before the parliament is an essential step.

What a ‘forgotten’ Torres Strait Island Paralympian teaches us about representation, achievement and history

Source: The Conversation (Au and NZ) – By Alistair Harvey, UQ Amplify Research Fellow, The University of Queensland

The full significance of Harry Mosby’s silver-medal win in the men’s discus at the 1976 Paralympic Games in Canada was unrecognised for 45 years: Paralympics Australia thought he was a Western Australian.

In truth, Mosby was a Torres Strait Islander from Masig (Yorke Island), one of around 600 Islander men who worked to support his family on the Australian mainland during “railway time” from the late 1950s to the early 1970s.

Until 1965, the Queensland Torres Strait Islander Act controlled resident Islanders’ lives, including their wages and movements.

Mosby, who left the Strait in 1963 and lost both legs in a railway accident in the Pilbara in 1968, was among the first to leave.

Paralympics Australia now recognises Mosby not only as a Torres Strait Islander but also as the first, and only, Paralympian from the Strait.

This recognition came in 2021 following our (Phillips and Osmond) research on the history of the Australian Paralympic movement, in collaboration with Paralympics Australia.

The longstanding misunderstanding about Mosby’s origins existed because he was based in Perth, rehabilitating from his accident, when he was selected to represent Australia in 1976.

A comment made in an oral history interview by his teammate Frank Ponta referring to Mosby as a Torres Strait Islander, led us to investigate his origins and connected us to his family on Masig.

Our experience with the Paralympics’ history project and encounter with Mosby led us to ask questions about other pioneering Indigenous Paralympians and Olympians.

Aboriginal trailblazers

The first Aboriginal Paralympian was wheelchair basketballer Kevin Coombs, who competed in the inaugural Paralympics in Rome in 1960, the first of his five Paralympics.

A Wotjobaluk man from Balranald, NSW, Coombs began competing before the 1967 referendum, when Indigenous people went uncounted in the census. He was devastated to need an honorary British, rather than Australian, passport to compete in Rome.

Those games were the ninth iteration of the Stoke Mandeville Games, the predecessor to the Paralympics, held since 1948, yet no identified Indigenous athletes participated in those earlier events.

Aboriginal and Torres Strait Islander Olympians and Paralympians unveiled an athlete-drafted plan for Brisbane 2032.

Historic questions

Mosby’s and Coombs’ Paralympic experiences raise questions about Indigenous participation in the Olympic Games.

Ask yourself: who were the first Aboriginal and Torres Strait Islander Olympians? Which games and sports did they compete in? How did government legislation shape their opportunities? How did they avail themselves of these opportunities? Were these athletes recognised as Indigenous at the time?

The first Aboriginal athletes to participate in the Olympics, in Tokyo 1964, were boxers Adrian Blair and Frank Roberts, and basketballer Michael Ah Matt.

All three learned their sports under the restrictions imposed by state-based legislation governing the lives of Aboriginal people: Blair was from Cherbourg, an Aboriginal settlement in Queensland; Ah Matt grew up in Darwin, while Roberts was from Cubawee Aboriginal Reserve in NSW.

Even though these men experienced broad systemic racism like other Aboriginal people at the time, they were selected in the team for Tokyo.

Nevertheless, the Australian Olympic Federation did not acknowledge their Aboriginal identity.

This was consistent with government policies of assimilation requiring Aboriginal people to deny their cultures, languages and identities in order to “blend in” to White Australia.

Assimilation helps to explain that while we celebrate Cathy Freeman and Patty Mills, we know little about their Aboriginal and Torres Strait Islander predecessors.

Sixty Indigenous Australians known to the Australian Olympic Committee have represented the nation at the Olympics.

A platform to shine

The modern Olympics began in 1896 but it took until 1964 before any athletes who were identified as Aboriginal were selected. There were outstanding athletes, however.

Yorta Yorta man Lynch Cooper was the world’s professional sprint champion in 1929, for example, and Yiman boxer Jerry Jerome claimed the Australian middleweight crown in 1912.

But they were professionals at a time when the Olympics enforced an amateur/professional divide.

While regimes of control over Aboriginal people restricted access to amateur sports, many athletes were attracted to professional sports to escape poverty.

Aboriginal professional athletes on the world stage in this period like Lionel Rose were ineligible for Olympic competition.

Others, like Evonne Goolagong, were professional but played in sports that weren’t on the Olympic program.

Torres Strait Islanders had an even longer wait than Aboriginal athletes to enter the Olympic arena – Danny Morseu, who played basketball in Moscow 1980, was the first.

Like their Aboriginal cousins seeking to escape poverty through professional sports, many Islanders sought to escape government control over work and wages.

While Mosby was one of the earliest Islander men to leave, Morseu’s generation had greater freedoms and he was able to move to Melbourne to pursue his basketball career.

Australian women first competed in the summer Olympics in 1912.

It was not until 1992, however, that an Indigenous woman competed – breaststroker Samantha Riley.

Hockeyroo Nova Peris became the first Indigenous Australian woman to win a gold medal, in 1996, and in 2000 Freeman became the first Aboriginal athlete to claim an individual Olympic gold.

The delayed debut of Indigenous women reflects the double fold of discrimination – gender and racism – they faced in sport.

Indigenous Australians experienced nearly two centuries of containment and control by the time Aboriginal and Torres Strait Islanders represented Australia at the Paralympic and Olympic Games.

Paris will see more First Nations athletes in competition, adding to the 60 recognised Indigenous Olympians and 16 Paralympians who competed between 1960 and 2021.

As we watch them perform, let’s not forget their trailblazing forebears and ensure future Indigenous Olympians and Paralympians don’t face similar challenges.

Truth telling or economic development? To deliver for Indigenous people, the government must do both

Source: The Conversation (Au and NZ) – By Heidi Norman, Professor, Faculty of Arts, Design and Architecture, Convenor: Indigenous Land & Justice Research Group, UNSW Sydney

In August, Prime Minister Anthony Albanese attended the Garma Festival and announced the government’s new Indigenous policy direction. This agenda rises from the ashes of the Voice to Parliament referendum, almost a year after it was voted down.

Alongside continuing to address Closing the Gap measures, the new direction emphasises economic empowerment and development. Albanese connected closing the gap with the “new opportunities” arising in the global economy, including in sectors such as defence, security, critical minerals and renewable energy.

At the same time, he seemed to distance himself from establishing a truth-telling commission, or Makarrata, as the government had promised to do. Instead, he spoke about doing things that “make a practical difference”.

But economic development and truth telling are not mutually exclusive. In fact, truth telling is crucial for the success of any economic plan for Indigenous people.

View From The Hill: Anthony Albanese shapeshifts on Makarrata


Not one without the others

The Uluru Statement from the Heart had three main components: Voice, Treaty and Truth. The latter two remain open for government action.

In what appears to be a reversal of the government’s earlier commitment to reforms, Treaty is now viewed as a state and territory responsibility. Treaty negotiations are progressing at different rates across the country.

Truth telling, on the other hand, has been recast by the federal government as a community-led healing and shared histories project.

Describing truth telling and Treaty as the concept of “coming together of people through engagement”, as Albanese did, risks the economic empowerment agenda repeating the mistakes of past. Truth and Treaty are vital to address economic empowerment of First Peoples.

Albanese has acknowledged this. But avoiding the exploitation and injustices of the past requires more than just words.

There need to be mechanisms to ensure fair negotiations, access to information and informed decisions. A Makarrata Commission could assist in this process.

Makarrata is a Yolngu concept describing resolving disagreement and settling on future peace. It offers a process of engaging as equals to settle our differences. It could be a useful forum to establish the framework and standards for fair negotiation on economic matters.

New-old approach

Government support for Aboriginal economic development after colonisation is not new.

The first initiative of the Commonwealth after the 1967 referendum was to establish a fund to support Aboriginal enterprise development.

In fact, the shift from authoritarian welfare administration to greater autonomy was conceived in terms of economic development.

But First Peoples had not only been dispossessed within traditional economies, but also in the colonial and settler economies in the cities, bush and in more remote areas.

The remaking of Aboriginal economies in vastly different settings has been underway since. How best to support and advance this has been the focus of debate.

Public intellectual Noel Pearson has argued that collective approaches to Aboriginal economic development, as advanced from the 1970s, lack the necessary conditions for the market to thrive.

Others say there are alternate economic models that accommodate market and traditional economies, while others have pointed to the opportunities for First Nations peoples partnering with the resources industry.

Countering this claim are studies of the power imbalance often at play. Where agreements are struck and royalties negotiated, there is often no improvement in the material conditions of Traditional Owners whose lands have been impacted by mining.

An example of efforts to support the rebuilding of Aboriginal economies includes land rights laws, particularly in New South Wales. Since 1983, recognising Aboriginal ownership of land has been central to realising Aboriginal self-determination.

There are several examples of successful land council enterprises that create jobs, put Aboriginal people back on country, and generate benefits for land council members. Significantly, the land council estate is increasingly stitched into wider planning and development agendas.

But NSW is just one state, and the results have been uneven.

The most significant development in First Peoples economic empowerment has been achieved by policies to support individual Aboriginal small businesses. Indigenous procurement policies, including at a federal level, have seen large numbers of Indigenous enterprises emerge. These are making significant contributions to the economy and jobs for First people.

Indigenous rights central

The government’s new approach draws heavily from recent work done at the Australian National University.

The university’s First Nations Portfolio has led a series of dialogues over the past two years to advance the economic empowerment of First Nations people. Its final report, Murru waaruu, says there needs to be a “paradigm shift” from a transactional relationship that First Nations peoples have with governments and industry, to one of genuine partnership. This would involve an equity stake in economic projects.

The final report argues:

[…] an economic self-determination agenda is about providing First Nations communities and enterprises with opportunities to engage in the Australian economy and to share in wealth creation opportunities on their own terms.

While there has been a range of programs and institutions to support Indigenous business, there has never been a comprehensive economic policy framework for First Nations people in Australia.

But the leading and crucial recommendation arising from the report is the need for any economic development plan to be rooted in Indigenous rights. The best rundown of these rights is the United Nations Declaration of the Rights of Indigenous Peoples.

Australia is a signatory to the declaration. This means any plans should include free, prior and informed consent from First Nations people. If done this way, we can prevent harm and Indigenous communities can take up opportunities safe in the knowledge that they support and sustain their peoples’ self-determination.

In this way, Treaty and truth telling continue to be relevant and necessary to advance economic security.

Truth telling raises awareness and addresses structural factors that create the conditions of disadvantage.

Treaties and other agreements are important mechanisms for establishing the principles and framework for advancing economic empowerment.

Land councils and Traditional Owner groups can spend years in costly litigation to secure their rights and interests. If the government wants to avoid this and make doing business easier for Indigenous people, we need baked-in institutions. Truth and Treaty are an unavoidable part of that.

‘Room for everyone’: how Kīngi Tūheitia’s message of unity offered an alternative to divisive Treaty politics

The numbers attending the tangihanga for Kīngi Tūheitia Pōtatau Te Wherowhero VII attest not only to the enduring significance of the Kīngitanga movement, but also to its political relevance at this point in Aotearoa New Zealand’s history.

Tūheitia, the seventh Māori monarch, died on Friday at the age of 69. Prime Minister Christopher Luxon said he was “somebody who tried to pull everyone together – Māori and non-Māori”.

Luxon’s government, of course, has been accused of doing the very opposite through policies designed to limit Māori influence in public life. With the ACT Party’s hugely contentious Treaty Principles Bill about to be introduced, it is the risk of pushing people apart that worries many.

The Kīngitanga’s own founding principle of kotahitanga – unity – is therefore as relevant as ever.

Kotahitanga

Other than parliament, the Kīngitanga (King Movement) is New Zealand’s longest continuing political institution. Formed in 1858, it predates political parties. It was founded with the unifying “korowai” (cloak) of stopping the colonial sale of land, ending inter-tribal warfare, and preserving Māori culture.

Although not all iwi (tribes) joined the movement, its original purpose of stopping colonial expansion remains universal, and makes it nationally significant. The hui-a-iwi (national meeting) Tūheitia called in January to resist the new government’s policies to diminish the role of te Tiriti o Waitangi (Treaty of Waitangi) attracted 10,000 people.

Shortly afterwards, the prime minister gave a firm commitment that his National party would not support into law its coalition partner’s Treaty Principles Bill. More recently, the Waitangi Tribunal found the bill was “unfair [and] discriminatory”.

So, too, was the 1863 invasion of the Waikato, which saw the confiscation of 1.2 million acres of Māori land. For the government of the day, resistance amounted to rebellion against the sovereign authority of the Crown.

Invasion and resistance

In 1884, the second king, Tāwhiao, travelled to London to seek restitution and “renew the words” of the Treaty. Queen Victoria wouldn’t meet him. The British Colonial Office said land confiscation was a matter for the New Zealand government.

In doing so, Britain rejected the idea of te Tiriti being a personal relationship between Victoria and the chiefs who signed the agreement, after English missionaries convinced them this was its intent.

While it’s a sharply contested policy, it’s perhaps not surprising Te Pāti Māori proposes severing New Zealand’s connection with the British monarch so that te Tiriti may be honoured according to the party’s interpretation of the agreement.

But it is because the Kīngitanga stands apart from party politics that it remains influential, with kotahitanga its essential and enduring ambition.

Reparation and redress

Partial restitution for the Waikato invasion was achieved in 1995 with the Waikato Raupatu Claims Settlements Act, which was symbolically given royal assent by Queen Elizabeth II.

The act’s material substance flowed from admitting the Crown’s “unconscionable” conduct. It accepted the confiscated lands made a significant contribution to the wealth and development of New Zealand, while Waikato iwi were deprived of the benefit of their lands.

The NZ$170 million settlement was a fraction of the land’s estimated value in 1995 of $12 billion. So it wasn’t a fair and equal act of reconciliation. Unity was achieved, perhaps, through Waikato generosity.

Nevertheless, further payments meant the settlement was increased to ensure relativity with later settlements with other iwi. In 2022, total payments had reached $390 million. Post-settlement investments had seen the Waikato asset base grow to $2.2 billion by 2023.

Such Māori success is important, and provides a foundation for Tūheitia’s call for unity.

Leadership beyond parliament

Celebrating the 18th anniversary of his coronation last month, Tūheitia addressed the contemporary meaning of kotahitanga:

Our kotahitanga shouldn’t be focused on fighting against the government. Instead, we need to focus on getting in the waka and working together. Mana motuhake has room for everyone.

Significantly, he added:

I don’t want politicians to lead the conversation about nationhood.

Leadership beyond conventional party politics may take some of the tension from contemporary Treaty policy debates.

Only last week, the prime minister objected to a ten-year-old Waitangi Tribunal finding that Māori did not cede sovereignty to the British Crown under te Tiriti, telling parliament, the “Crown is sovereign”.

This was meant as an assertion of colonial authority – as if government and Māori can’t have political authority at the same time. As if mana motuhake – autonomy and self-determination – doesn’t allow “room for everyone”.

If kotahitanga is the objective, there must surely be space for everybody to say, as Tāwhiao did, “Maku ano e hanga toku nei whare” – I will build my own house.

Speaking about the Treaty Principles Bill at the hui-a-iwi in January, Tūheitia said, “There’s no principles, the Treaty is written. That’s it.”

The coming weeks and months will test that view – and demonstrate the place of the Kīngitanga as a political and cultural institution outside parliament and political parties. The new monarch’s job will be an important one at an important time in the New Zealand story.

Newspoll remains tied at 50–50, but Albanese’s net approval slumps

Source: The Conversation (Au and NZ) – By Adrian Beaumont, Election Analyst (Psephologist) at The Conversation; and Honorary Associate, School of Mathematics and Statistics, The University of Melbourne

A national Newspoll, conducted August 26–30 from a sample of 1,263, had a 50–50 two-party tie between Labor and the Coalition, unchanged from the previous Newspoll three weeks ago. This is the first time this term there have been two successive ties in Newspoll.

Primary votes were 38% Coalition (down one), 32% Labor (steady), 12% Greens (steady), 7% One Nation (up one) and 11% for all Others (steady).

Anthony Albanese’s net approval slumped five points to -13, with 54% dissatisfied (up three) and 41% satisfied (down two). This is Albanese’s worst net approval in Newspoll since November 2023, after the failure of the Voice referendum.

The graph below shows Albanese’s net approval in Newspoll this term. The plus signs are Newspoll results and a smoothed line has been fitted.

Peter Dutton’s net approval was down three points to -13, and this is the first time Albanese and Dutton have been equal on net approval in Newspoll since November 2023. Albanese led Dutton by 45–37 as better PM (46–39 previously).

When asked about inflation if Dutton and the Coalition were in government, 24% said inflation would be lower than it is now, 18% higher, 41% about the same and 17% were undecided.

While the government has had other problems in the past few weeks, I believe inflation is still its main problem with voters. Last week’s Morgan consumer confidence reading of 82.6 was the highest six-week average since February, but consumer confidence has been below 85 for a record 82 successive weeks.

YouGov poll tied at 50–50

A national YouGov poll, conducted August 23–28 from a sample of 1,543, had a 50–50 tie, a one-point gain for the Coalition since the mid-July YouGov poll. Primary votes were 37% Coalition (down one), 32% Labor (up one), 13% Greens (steady), 8% One Nation (up one) and 10% for all Others (down one).

It’s strange that the two-party vote improved for the Coalition despite the drop in the Coalition’s primary vote and gain for Labor. Rounding probably explains this.

Albanese’s net approval was down one point to -11, with 52% dissatisfied and 41% satisfied. Dutton’s net approval was also down one to -5. Albanese led Dutton by 43–38 as preferred PM (45–37 in July).

In a forced choice question, 67% of Australian voters would vote for Democrat Kamala Harris for US president, while 33% would vote for Republican Donald Trump. The only group voting for Trump was One Nation voters (80–20 for Trump).

Essential poll: Labor gains to lead by 48–46

A national Essential poll, conducted August 21–25 from a sample of 1,129, gave Labor a 48–46 lead including undecided, after a 47–47 tie in the early August Essential poll. Primary votes were 33% Coalition (down one), 29% Labor (up one), 13% Greens (down one), 7% One Nation (steady), 1% UAP (steady), 11% for all Others (up two) and 6% undecided (steady).

Despite Labor’s improvement on voting intentions, Albanese’s net approval dropped seven points since late July to -10, with 50% disapproving and 40% approving. This is Albanese’s worst rating in Essential this term. Dutton’s net approval was steady at +1.

By 44–30, voters supported Dutton’s call to pause arrivals of Palestinian refugees. There was a 42–42 tie on whether immigration to Australia is generally positive or negative (46–34 positive in November 2023).

While voters were narrowly positive on immigration’s impact on the economy (42–41), they were negative on its impact on jobs (51–35), the environment (43–24) and strongly negative on house prices (69–15).

On the government’s response to the Israel-Gaza war, 32% said it was too supportive of Israel, 16% too harsh on Israel and 52% were satisfied. These figures are unchanged from June. On Israel’s military action in Gaza, 39% (up one since June) said Israel should permanently withdraw, 21% (steady) agree to a temporary ceasefire and 17% (up two) said Israel’s military action was justified.

Redbridge and Morgan polls

A national Redbridge poll, conducted from a sample of 2,000, gave Labor a 50.5–49.5 lead, a two-point gain for Labor since the mid-July Redbridge poll. Primary votes were 38% Coalition (down three) and 33% Labor (up one). No other primary votes or fieldwork dates have been released yet.

A national Morgan poll, conducted August 19–25 from a sample of 1,701, gave the Coalition a 50.5–49.5 lead, a one-point gain for the Coalition since the August 12–18 Morgan poll.

Primary votes were 39.5% Coalition (up one), 29.5% Labor (down one), 13% Greens (down 0.5), 4% One Nation (steady), 9% independents (up 0.5) and 5% others (steady).

The headline figure is based on respondent preferences. By 2022 election preferences flows, there was a 50–50 tie, a one-point gain for the Coalition.

EMRS Tasmanian poll: little change since May

An EMRS Tasmanian state poll, conducted August 14–21 from a sample of 1,000, gave the Liberals 36% of the vote (up one since May), Labor 27% (down one), the Greens 14% (down one), the Jacqui Lambie Network (JLN) 8% (up one), independents 14% (steady) and others 3% (steady).

Liberal incumbent Jeremy Rockliff held a 45–30 lead over Labor’s Dean Winter as preferred premier (40–32 in May).

At the March state election, three JLN MPs were elected, but analyst Kevin Bonham reported on August 25 that two of these MPs had been expelled by the party.

So the current standings of the Tasmanian lower house are 14 Liberals out of 35, ten Labor, five Greens, five independents and one JLN. The Liberals need four of the six crossbenchers to pass legislation opposed by Labor and the Greens. The EMRS poll was done before the JLN blew up.

NT likely election result

For the August 24 Northern Territory election, the ABC is giving the Country Liberal Party (CLP) 17 of the 25 seats, Labor four, independents three and one seat (Nightcliff) is undecided, but Labor is expected to beat the Greens after distribution of preferences.

The Greens were initially seen as likely to beat the CLP in Fannie Bay on Labor preferences, but the flow of Labor preferences to the Greens was weaker than expected, and the CLP will gain Fannie Bay from Labor.

The NDIS is failing profoundly disabled people who are stuck in group homes. Here’s how to fix this

Source: The Conversation (Au and NZ) – By Sam Bennett, Disability Program Director, Grattan Institute

Reshetnikov_art/Shutterstock

The National Disability Insurance Scheme (NDIS) is transforming the lives of hundreds of thousands of Australians with disability. For the first time, many can get the help they need to live more independently and be part of society.

And yet, the NDIS is failing people with the most severe disability: people who need housing and intensive living support.

Overwhelmingly, people in this part of the scheme live in group homes, with little choice over where they live, who they live with and who provides their support. Worse still, they face high rates of violence, abuse, neglect and exploitation.

Intensive housing and living support is one of the most costly parts of the NDIS, coming in at around A$15 billion in 2023–24. Although this is a small group – about 7% of all NDIS participants – total support packages for these participants make up about 37% of total scheme spend.

For this price tag, Australians with disability deserve, and taxpayers expect, quality services.

New analysis in the Grattan Institute’s latest report shows how the government can create innovative alternatives to group homes that cost the same or less money.

Create alternatives for housing and living support

There are better alternatives to group homes: these are known as individualised living arrangements. The United Kingdom, Canada, and, closer to home, Western Australia , have reformed disability housing and introduced new living arrangements which offer people greater choice and a more individualised approach.

Individualised living arrangements are integrated into the community as much as possible. They draw on a mix of supports, from formal (paid-by-the-hour support workers), to semi-formal (hosts or flatmates who receive a subsidy for their expenses), to informal (family and friends).

A host arrangement is where an adult with disability on the NDIS lives with a “host family” or “host flatmate”, who is not related to them, in the host’s home, becoming part of the household. A host might be a couple or an individual, and they provide semi-formal support while going about their everyday activities.

Individualised living arrangements draw on formal and informal support.

A home-share arrangement is similar: an adult with disability on the NDIS lives in their own home (owned or rented) with a flatmate who provides support. Hosts and flatmates might help with emotional support, companionship, cooking, cleaning, overnight help and other household tasks, and they receive a subsidy for their expenses.

Based on our estimates, individualised living arrangements can be cheaper than group homes set at a one-to-three benchmark (one support worker for every three disabled residents), as recommended by last year’s Independent Review of the NDIS.


Individualised living arrangements cost the same or less than group
homes than the review’s proposed 1:3 benchmark


NDIS Review (2023); Grattan analysis of unpublished provider data (2024)

Individualised living arrangements are not only cost effective, they give people with disability choice about where they live, who they live with, and who provides their support.

Share houses, not group homes

Rather than group homes, which are run more like service facilities than people’s homes, we recommend reforms to establish share houses. So when people with disability decide to live with other people with disability and share supports, they can choose the rhythms of their daily life and who looks after them.

Moving to a system where paid support workers’ time can be shared can dramatically reduce the cost of supports, as this chart shows. This is critical in a scheme facing enormous cost pressures.

We recommend system changes too, including:

  • separating housing and living supports in shared accommodation settings, as the Independent Review of the NDIS recommended
  • enforceable service agreements (similar to contracts) between people with disability and providers
  • support from housing and living “navigators” to establish individualised living arrangements.
  • mandatory registration for providers of housing and living support, and unannounced inspections.

To give people with disability options about where they live, the government should introduce a rental payment to help people move out of their group homes and into the private rental market.

A growing feature of share houses could be sharing both formal and semi-formal support. Combining the economy of scale from sharing support workers, with semi-formal support from a housemate, would be a cost-effective way to run share houses in the future.

Disabled people should be able to choose who they live with.

Time for the NDIS to get on board

Right now, people with disability have to provide copious evidence about the supports they need, and are then told what they can have and how much – often without having met the decision maker.

So people are locked into options before they’ve had a chance to try out alternatives that might be better, safer and cheaper.

Our proposal is for people with disability get a flexible budget up front. Then planning can start.

People should have access to independent advice to plan their best life within their budget. The National Disability Insurance Agency should commission housing and living navigators to give people with disability this vital help.

All of us try out different living arrangements and gradually work out what is best for us. We need information and options to choose from to get the best result – this is the same for people with disability.

Getting services right for people with the most severe disability, who need 24/7 living support should be the litmus test for any government seeking to get the NDIS back on track. Our research shows genuine choice and higher-quality services are within reach for Australians with disability – and governments don’t have to spend buckets more to get it done.

‘It’s time to give up on normal’: what winter’s weird weather means for the warm months ahead

Source: The Conversation (Au and NZ) – By David Bowman, Professor of Pyrogeography and Fire Science, University of Tasmania

Heavy winds struck south-east Australia over the weekend as a series of cold fronts moved across the continent. It followed a high fire danger in Sydney and other parts of New South Wales last week, and a fire in south-west Sydney that threatened homes.

The severe weather rounds out a weird winter across Australia. The nation’s hottest ever winter temperature was recorded when Yampi Sound in Western Australia reached 41.6C on Tuesday. Elsewhere across Australia, winter temperatures have been way above average.

We can look to the positives: spring flowers are blooming early, and people have donned t-shirts and hit the beach. But there’s a frightening undercurrent to this weather.

Earth’s climate has become dangerously unstable, and it’s only a matter of time before we get the bad combination of hot and dry weather, strong winds and a spark. None of this should come as a surprise. The sooner we stop expecting Australia’s weather to be “normal”, the sooner we can prepare for life in a wild climate.

The green is deceiving

The landscape around Sydney – and in fact, across much of south-east Australia – is very green at the moment. That’s because we’ve had a couple of years of good rains which triggered an explosion of vegetation growth.

The below NASA satellite image reveals the picture in stark detail. It’s certainly lush out there at the moment.

But the problem with climate change is that weather conditions can turn on a dime. This August was a case in point. At month’s end, much of Australia was hit by a record-breaking heatwave and damaging winds – conditions that can dry out a green landscape with devastating efficiency, turning it into fuel for a bushfire.

The dangerous fire weather that struck Sydney this week came as a surprise to many. But in reality, these abnormal conditions are the new normal.

We must open our minds to this, if we want to be prepared.

A climate off the rails

The year 2023 was Earth’s hottest on record. And 2024 looks likely to be hotter still.

In Australia, the last 12 months have provided all the evidence we need that our climate is wobbling on its rails.

In October 2023, Victoria’s Gippsland region suffered unseasonably early bushfires, then soon after battled heavy rain and flooding.

And Tasmania, where I live, has been gripped by drought. This February was Hobart’s third driest in 143 years. But over the weekend we were hammered by a deluge of rain and wind.

This climate instability is setting up bad fire conditions. Not everywhere in south-east Australia will be hit by fire, but it will happen somewhere. It could be the hinterlands or the coast. It will depend on how our erratic climate behaves in the coming months.

Let’s stick with the Tasmania example. Sure, the surface soils are now nicely saturated. But that will lead to a burst of grass and other vegetation in spring. If the dry weather returns and the temperatures heat up in summer, the fine fuels will dry out and become dangerously combustible.

All we need then is a windy day and a spark, and a nightmare fire will soon be racing across the landscape.

Canada on fire

Of course, Australia is not the only country facing climate instability and a worsening fire risk.

Canada suffered a catastrophic wildfire season in 2023 – one of the most severe on record. It burnt almost 15 million hectares and forced the evacuation of 232,000 people.

Smoke produced by the fires affected communities up to 1,000 km away, such as in southern Canada and on the east coast of the United States.

A recent paper in the journal Nature Communications outlined why. It pinpointed early snowmelt, early-season drought conditions and intense heat. In fact, the average temperature in Canada from May to October last year was 2.2°C higher than the 30-year average.

The researchers said human-caused climate change exacerbated the fire’s effects. It went on:

The disproportionate effect a few days of extreme weather can have on the total area burned is also evident in this fire season, leading to worrisome prospects given projected future conditions.

Normal no longer exists

It’s always been difficult to forecast fire seasons in Australia, due to our natural climate variability.

But now we are seeing climate instability layering over itself: background dryness, wet seasons bringing a proliferation of fuels, and above-average temperatures.

Eventually we’ll get unlucky and experience extremely strong winds thrown into the mix. That’s when catastrophic fires are most likely to occur.

As we saw in the Black Summer of 2019–20, and again in Canada last year, some fires are so intense they completely overwhelm fire suppression strategies.

Under climate change, the likelihood of getting a bad combination of weather conditions is increasing. So what’s the remedy?

Australia really must start making our communities more resilient. Serious and sustained adaptation is needed. As my research has outlined, this requires the careful integration of:

  • community education programs
  • research and development to design fire-safe homes, gardens, communities and bushland
  • incentives and penalties to ensure adaptation measures are implemented.

As this winter has shown, Australia’s climate is entering a different phase. It’s time to give up on “normal” weather. The game is changing and we have to adapt.

We found teenage girls don’t know vulvas from vaginas or when their menstrual cycle starts

Source: The Conversation (Au and NZ) – By Felicity Roux, Researcher, Curtin Medical School, Curtin University

ClareM/Shutterstock , CC BY

It is important for everyone – but especially girls, women and people who menstruate – to understand how ovulation and menstruation work.

The menstrual cycle is a key indicator of overall health and
sadly, issues such as pain, mood swings or abnormal bleeding are common. These have been associated with missing school, avoiding sport and mental health challenges.

Understanding the menstrual cycle empowers patients to give an accurate history to doctors to maintain good health. This knowledge is also needed to navigate major milestones such as menarche (the first bleed), fertility, pregnancy, breastfeeding and menopause.

Given how important menstrual health literacy is for half the population for some 40 years of their lives, it would be reasonable to suppose it is a core part of learning at school.

Unfortunately, our new research suggests it is not.

It’s time to teach the whole story about ovulation and its place in the menstrual cycle


Our research

We surveyed teenage girls about their knowledge of the menstrual cycle as part of our broader work, developing and testing a holistic menstrual health literacy program for schools (which Curtin University has identified as having commercial potential).

To establish what school students need to know, we consulted 35 experts in medicine and education. The experts said at a minimum, girls need to know about ovulation, menstruation and basic anatomy.

We then surveyed 297 female* students (average age 15) who had attended puberty and reproductive science lessons at school. More than 92% of respondents had had their periods for about two years on average.

They were from two single-sex and seven co-educational schools in the Catholic and independent sectors in Western Australia.

We surveyed almost 300 Western Australian girls from single-sex and co-ed schools about menstruation.

Our findings

Our survey revealed alarming gaps in teenagers’ basic knowledge about anatomy, ovulation and menstruation.

Almost half of respondents (48.6%) did not know day one of the menstrual cycle is the first day of menstruation. Less than 9% understood ovulation happens about two weeks before their period.

More than 60% of respondents confused the vulva (external genitalia) with the vagina (the internal canal that extends from the vulva to the cervix).

Regarding fertility, 43% incorrectly selected 45 years (rather than 35 years) as the age for when achieving pregnancy becomes increasingly difficult.

Most of those surveyed (91%) got their information from their mothers, with others relying on friends or apps. Almost 70% reported they got period pain. About 65% reported mood swings and 45% reported nausea during their cycles.

The type of school does not have an impact

Previous research suggests girls prefer to learn about menstruation without boys around.

However, there was little difference between the type of school a student attended – single-sex or co-ed – and students’ level of knowledge about the menstrual cycle.

Similarly, there was little difference in students’ knowledge between Catholic and independent schools.

This was surprising, since the Catholic Church supports natural fertility regulation. This needs a solid, accurate understanding of the menstrual cycle to be as effective as possible.

We also found students who used period-tracking apps were no more likely to have basic knowledge of their cycles than peers who did not use these apps. This is similar to findings from previous studies.

Why we need to do more

Many female students in our study showed poor levels of menstrual health literacy.

This suggests there is a pressing need for schools to improve the education they provide about the menstrual cycle. As our previous research recommended, this needs to use evidence-based information presented in clear, accessible ways.

If patients cannot answer doctors’ basic questions, such as “when was your last period?” or “where is this happening in your body?”, it could impact diagnoses and treatments. It also means they may not even go to a doctor, dismissing debilitating pain or heavy bleeding as “normal”.

Our ongoing research will train school staff in menstrual health education and care, which may be expanded to other school systems and states in time.


In this article we use terms such as females or girls in relation to sex (biological characteristics or reproductive organs), which may differ from gender identity.

Military veterans with PTSD face an agonising choice: the stigma of declaring it to employers or being denied support

Source: The Conversation (Au and NZ) – By Richard O’Quinn, Lecturer in Management & Leadership, The University of Queensland

Australia is home to almost half a million military veterans, most of whom are in the workforce.

But most – around 60% – live with long-term health problems.

About half of these face enduring mental health challenges, including post-traumatic stress disorder, anxiety, depression and an increased risk of suicide.

Disclosing these conditions could allow sufferers to get workplace support, but many keep quiet, in part because of fear of stigma.

And keeping quiet can build on itself.

Where full disclosure is required, particularly for Australian government positions requiring security clearances, veterans who keep quiet can find it necessary to stay quiet and even seek private, external assistance without disclosing it.

Keeping quiet has consequences

The result can be self-harm or a mental health crisis in workplaces in which their employers are unaware of their conditions and unable to offer help.

Our team at the University of Queensland has conducted a study of the circumstances in which veterans disclose in order to understand how they juggle the competing needs to reach out and fit in.

The project is funded by the university and an apprentice placement group East Coast Apprenticeships.

Although it is too early to share results, our surveys and interviews point to a spectrum of approaches to disclosure.

At one end of the spectrum, veterans tell us they won’t reveal their medical concerns to anyone, sometimes including their spouses.

This can be because veterans feel no one is capable of understanding or relating to their situations and any disclosure might harm relationships.

Being publicly ‘outed’ can be humiliating

At the other end of the spectrum, veterans face official demands for repeated disclosure, sometimes every six months.

They feel as if their private lives are constantly on display to their supervisors and an unknown number of human resource managers.

One talked about being publicly “outed” when applying for government positions.

In a room with hundreds of applicants, he said, veterans were asked to raise their hands if they had been diagnosed with post-traumatic stress disorder. They were then given multi-page booklets to fill out detailing their conditions, treatment and medication regimes long after fellow applicants had departed.

For many, it’s a complicated juggle

Another veteran described having to perform a complex decision-making process each time a contract was up for renewal or a new contract was offered.

The veteran took into account the length of the contract, the contracting firm’s health policies and reporting requirements and what the firm said it offered for mental health support.

Importantly, this veteran also researched what the contracting firm actually did by asking around among fellow veterans.

Only when the veteran felt capable of calculating their own understanding of the risk of disclosure would they consider proceeding with the contract.

Many, many employers have their employees’ best interests at heart but are unable to convincingly make that known.

One business owner (a veteran himself) said the best way to gain veterans’ trust was to first disclose some aspect of his own health condition. It was a way of meeting the applicant halfway.

Our study has some way to run. There’s a chance its findings could save lives by making it easier for veterans to disclose their conditions and gain support.

Without sanctions, making companies disclose their environmental and social impacts has limited effect

Source: The Conversation (Au and NZ) – By Charl de Villiers, Professor of Accounting, University of Auckland, Waipapa Taumata Rau

As of last year, New Zealand’s largest companies and financial institutions have been required to disclose their climate-related risks and opportunities in their annual reports and regulatory filings.

This follows a global trend for businesses to be more upfront about their social and environmental impact. Companies are increasingly expected to provide safe and environmentally friendly products, and ensure all their activities are socially and environmentally responsible.

But does requiring businesses to report these things actually push them to make better decisions around climate and sustainability? While it is too early to tell from the New Zealand experience, a decade of data from Europe offers a better insight.

Our new research examining the effect of the European Union’s sustainability reporting regulation (Directive 2014/95/EU) on business performance suggests reporting is not always enough.

If New Zealand (and other countries) want businesses to take their impact on the climate seriously, our research suggests reporting requirements need to include sanctions for companies that fail to achieve basic environmental standards.

Regulating disclosure

Disclosure requirements related to social and environmental issues have two main objectives.

The first is to provide investors with the information they need to decide where to invest. The second is to enable the rest of society to understand the social and environmental impacts of business on everyone’s lives.

In discussing these issues, terms such as ESG (environment, social and governance), sustainability, triple bottom line, and integrated reporting, are often used interchangeably.

While this can be confusing, they all really just refer to anything that relates to the natural environment or society.

Several studies have shown investors find social and environmental disclosures useful for their decision making. In research published last year, we found investors were prepared to pay for additional environmental disclosures.

But whether these reporting requirements improve companies’ social and environmental performance is, perhaps, the more important question.

The EU directive our study examined requires large companies to report their performance on non-financial matters, including environmental issues, social and employee matters, human rights, anti-corruption and bribery.

We looked at the social and environmental performance of companies between 2009 and 2020 using information contained in ESG databases.

The 358 European companies included in our sample didn’t meaningfully improve after the directive. Nor did they improve when compared to the 470 companies in the United States in our sample.

This was a surprise, considering Europe is often perceived as placing a greater emphasis on social responsibility, while business in the US is associated with a strong investor focus.

An ineffective directive?

It is possible the EU directive did not have a major impact on social and environmental outcomes due to the absence of meaningful sanctions for companies that didn’t comply.

EU directives usually leave detailed implementation up to each country,. In this case, few countries have significant sanctions. Prior research has shown that a lack of meaningful sanctions often results in poor outcomes.

According to the data, the social and environmental performances of both the European and US companies are steadily improving – just not as a direct response to the EU’s reporting requirements.

That said, the sum total of legislation enacted both in Europe and the US is probably still improving companies’ environmental and social impact. And this must be something to applaud.

Sustainability reporting requirements, along with meaningful sanctions for companies that do not comply, can play a role in ensuring our economic system works for everyone.

Is Iran’s anti-Israel and American rhetoric all bark and no bite?

Source: The Conversation (Au and NZ) – By Shahram Akbarzadeh, Convenor of the Middle East Studies Forum (MESF), and Acting Director the Alfred Deakin Institute for Citizenship and Globalisation, Deakin University

On August 27, Ali Khamenei, the supreme leader of the Islamic Republic of Iran, told the newly elected president, Masoud Pezeshkian, and his cabinet that talking to the enemy may be useful.

In a thinly veiled reference to Iran’s engagement with the international community – and specifically the United States – Khamenei said Iran should not pin its hopes on such engagement, but that is no reason not to hold talks with the enemy.

This is the kind of green light that Pezeshkian needs to engage again with the International Atomic Energy Agency and Western countries on Iran’s nuclear program, and to engage with international interlocutors over its heightened tensions with Israel.

This statement seems to signal a desire to walk back from the brink of an all-out war with Israel over the assassination of Hamas political leader Ismail Haniyeh on Iranian soil in July and revert back to the mutual deterrence that had defined their relationship for years.

This, however, may not be an option given how much the region has changed over the past year.

Crossing a threshold in April

In April of this year, Israel targeted Iran’s embassy complex in Damascus, killing members of the Islamic Revolutionary Guards Corps.

This led to a carefully choreographed Iranian response. Iran could not ignore the Israeli attack, which the authorities condemned as an assault on Iranian sovereign territory, but did not wish to go into war with Israel. As a result, Iran reportedly gave advance warning of its impending response, which allowed Israel and its allies to shoot down most of the 300-odd missiles and drone fired from Iran.

This response was nonetheless seen as a victory in Iran, as it demonstrated its technological capacity to reach Israel. It also marked a departure from Iran’s default position of talking tough, but not getting involved in direct confrontation.

Iran clearly crossed a threshold in April, but seems very uneasy about the consequences.

Then, on July 31, Haniyeh was assassinated while on a visit to Iran. Although Israel has neither confirmed or denied responsibility, it is widely believed to have been behind it.

This has put the Iranian leadership in a bind. There have been calls from hardliners for retaliation to restore Iran’s image as a country that can defend itself and avenge the killing of a close ally. Khamenei has also insisted Israel will be punished for its action, but the time would be of Iran’s choosing.

It is clear the Iranian leadership cannot afford to look weak and risk damaging their standing among their allies and proxies in the region, which include Hamas, Hezbollah in Lebanon, the Houthi rebels in Yemen and other Shi’a militant groups in Iraq and Syria. But there are also other considerations that weigh heavily on their mind.

A crisis of legitimacy

A direct response to Israel could open a Pandora’s box. It would pave the way for further direct attacks by Israel, perhaps even targeted assassinations of Iranian leaders.

This is a real possibility. Israel has demonstrated its willingness to respond to any threat with force under the rubric of self-defence. It has also demonstrated its ability to carry out precision attacks in Iran, such as its retaliatory strike on a radar system in the city of Isfahan after Iran’s missile and drone attack in April.

Furthermore, such escalation presents the real risk of drawing the United States into the conflict.

The Iranian leadership has made an art of brinksmanship. Anti-Americanism is ingrained in the political discourse of the political elite and frames Iranian foreign policy. But Iran has so far avoided war with the United States, because that could risk everything.

The reason: Iran’s leaders are already nervous about their political future, and conflict with Israel and the US could seriously exacerbate the situation.

There is a major disconnect between large segments of society and the ruling regime at the moment. Two years ago, Iran was rocked by spontaneous anti-regime mass protests under the banner of “Woman, Life, Freedom”. They started in response to the death of Mahsa Amini in custody for not wearing her hijab properly, but soon morphed into an anti-establishment revolt that called for the “fall of dictatorship” and an end to the Islamic regime. The revolt was put down by force, arbitrary detentions and executions.

The death of President Ebrahim Raisi in a helicopter crash in May this year offered an opportunity for the ruling regime to seek a reconciliation with its reformist critics. Pezeshkian, a reformist parliamentarian, was vetted and approved to run in the election to replace Raisi with the intention of increasing voter turnout. Iran’s supreme leader has repeatedly pointed to the voter turnout rate as an indicator of the regime’s legitimacy.

Yet, the participation rate in the first round of the election was just 39.9% – the lowest in a presidential election in Iran’s history – and only reached 49.8% in the final round. This points to the depth of public disillusionment with the political system. Many reformists boycotted the election and dismissed the exercise as a sham and smokescreen for the ruling regime.

Iran’s crisis of legitimacy is at its highest point, making it ripe for another explosion. War with Israel or the United States can ignite this tinder box.

A potential solution for Iran?

So the Iranian leadership faces a dilemma. It cannot walk back from its anti-Israel and anti-US rhetoric. Tehran has built its foreign policy and formed an extensive network, the so-called Axis of Resistance, based on it. It cannot betray this pillar of its identity.

But acting on it would risk the survival of the regime. So the leadership has been looking for an increasingly difficult-to-find balance.

Hezbollah’s recent exchange of fire with Israel may have been the answer. By supporting Hezbollah, Iran can claim to have inflicted pain on Israel without striking itself.

This is aimed at restoring the status quo that existed before April. This strategy outsources the fighting to Hezbollah and Iran’s other proxies to protect the ruling regime from a direct confrontation and ward off an existential threat to the leaders’ rule.

But this may be wishful thinking. This strategy could give Israel the justification it needs to strike Iranian targets again. And this, in turn, could serve as the spark for the public’s pent-up frustration aimed at the brutality of the ruling regime.

Seismic echoes reveal a mysterious ‘donut’ inside Earth’s core

Source: The Conversation (Au and NZ) – By Hrvoje Tkalčić, Professor, Head of Geophysics, Director of Warramunga Array, Australian National University

About 2,890 kilometres beneath our feet lies a gigantic ball of liquid metal: our planet’s core. Scientists like me use the seismic waves created by earthquakes as a kind of ultrasound to “see” the shape and structure of the core.

Using a new way of studying these waves, my colleague Xiaolong Ma and I have made a surprising discovery: there is a large donut-shaped region of the core around the Equator, a few hundred kilometres thick, where seismic waves travel about 2% slower than in the rest of the core.

We think this region contains more lighter elements such as silicon and oxygen, and may play a crucial role in the vast currents of liquid metal running through the core that generate Earth’s magnetic field. Our results are published today in Science Advances.

The ‘coda-correlation wavefield’

Most studies of the seismic waves created by earthquakes look at the big, initial wavefronts that travel around the world in the hour or so after the quake.

We realised we could learn something new by looking at the later, fainter part of these waves, known as the coda – the section that brings a piece of music to its end. In particular, we looked at how similar the coda recorded at different seismic detectors were, several hours after they began.

In mathematical terms, this similarity is measured by something called correlation. Together, we call these similarities in the late parts of earthquake waves the “coda-correlation wavefield”.

By looking at the coda-correlation wavefield, we detected tiny signals stemming from multiple reverberating waves we wouldn’t otherwise see. By understanding the paths these reverberating waves had taken and matching them with signals in the coda-correlation wavefield, we worked out how long they had taken to travel through the planet.

We then compared what we saw in seismic detectors closer to the poles with results from nearer the Equator. Overall, the waves detected closer to the poles were travelling faster than those near the Equator.

Xiaolong Ma and Hrvoje Tkalčić

We tried out many computer models and simulations of what conditions in the core could create these results. In the end, we found there must be a torus – a donut-shaped region – in the outer core around the Equator, where waves travel more slowly.

Seismologists have not detected this region before. However, using the coda-correlation wavefield lets us “see” the outer core in more detail, and more evenly.

Previous studies concluded that waves moved more slowly everywhere around the “ceiling” of the outer core. However, we have shown in this study that the low-velocity region is only near the Equator.

The outer core and the geodynamo

Earth’s outer core has a radius of around 3,480km, which makes it slightly bigger than the planet Mars. It consists mainly of iron and nickel, with some traces of lighter elements such as silicon, oxygen, sulfur, hydrogen and carbon.

The bottom of the outer core is hotter than the top, and the temperature difference makes the liquid metal move like water in a pot boiling on the stove. This process is called thermal convection, and we think the constant movement should mean all the material in the outer core is quite well mixed and uniform.

But if everywhere in the outer core is full of the same material, seismic waves should travel at about the same speed everywhere, too. So why do these waves slow down in the donut-shaped region we found?

We think there must be a higher concentration of light elements in this region. These may be released from Earth’s solid inner core into the outer core, where their buoyancy creates more convection.

Why do the lighter elements build up more in the equatorial donut region? Scientists think this could be explained if more heat is transferred from the outer core to the rocky mantle above it in this region.

Ma and Tkalčić / Science Advances

There is also another planetary-scale process at work in the outer core. Earth’s rotation and the small solid inner core make the liquid of the outer core organise itself in long vertical vortices running in a north–south direction, like giant waterspouts.

The turbulent movement of liquid metal in these vortices creates the “geodynamo” responsible for creating and maintaining Earth’s magnetic field. This magnetic field shields the planet from harmful solar wind and radiation, making life possible on the surface.

A more detailed view of the makeup of the outer core – including the new-found donut of lighter elements – will help us better understand Earth’s magnetic field. In particular, how the field changes its intensity and direction in time is crucial for life on Earth and the potential habitability of planets and exoplanets.

Politics with Michelle Grattan: Reserve Bank’s Andrew Hauser says don’t read too much for Australia from US rates message

Source: The Conversation (Au and NZ) – By Michelle Grattan, Professorial Fellow, University of Canberra

Inflation remains top of mind as the Reserve Bank of Australia continues to keep interest rates on hold at a time when the United States Federal Reserve signals that it will start cutting rates.

One of the new lead architects behind the RBA’s thinking is Deputy Governor of the bank Andrew Hauser. Hauser formerly worked at the Bank of England and was chosen by Jim Chalmers, the first-ever senior appointment from overseas.

Hauser is just back from a meeting of central bankers in the United States at which the Chair of the US Federal Reserve, Jerome Powell, indicated it was time for US rates to fall. Will that produce a rethink in Australia where the Reserve Bank has flagged rates are likely to stay on hold until next year?  

Obviously, a significant part of the inflation story over the past two or three years has been a global story. It’s been related to global supply chains. It’s related, obviously, to the fallout from COVID and the impact of all of that on global demand.

But no. The decision on interest rates for the U.S. is for the U.S. to make. The decision on Australian rates is for the RBA and for the Australians to make, and we’re obviously […] hopeful that in due course we would follow suit. But we have to take account of the outlook for inflation in Australia. And inflation unfortunately is still a little bit too high at the moment.

Sadly, at the moment Australian inflation is a bit stickier than it has been in the US. And there’s a variety of reasons for that.

We’re not yet as confident, as Jay is in the US, that inflation in Australia is back on a sustainable path, back to target. And therefore we have to hold, rates where they are for the time being.  

On the delicate balance of reducing inflation and maintaining employment:

We have made a very conscious decision to set policy to bring inflation down, but to bring it down slowly enough that we protect the employment gains.

And the employment gains in Australia have been quite stunning, actually. Even now, the numbers that are coming through in the monthly releases, where people have been predicting an imminent downturn in the labour market, it could still happen, but even now, […] we are creating jobs at a pretty spectacular rate.

On his controversial speech questioning the certainty with which people proclaim about economic issues, which caused a stir among some commentators, Hauser says:

Look, frankly speaking, I think Australians would have every right to be bloody annoyed at a foreigner lecturing them to shut up and agree with the central bank, which would go down like a bowl of sick if an Australian tried to do that in the U.K. as well. But that wasn’t what I was trying to do it at all. In fact, it was the exact opposite. I was trying to make the case for humility but not for a lack of diversity of views.

I’ve loved my short time in Australia so far, and I’m here to listen, learn and serve. And it’s been quite nice actually – [I] had quite a long list of people sending their private support for the messages I was trying to give in the days after the speech.

Technology has helped para athletes compete for decades. But it can also create an unfair advantage

Source: The Conversation (Au and NZ) – By John Cairney, Professor and Head of Human Movement and Nutrition Sciences; Director, The Queensland Centre for Olympic and Paralympic Studies, The University of Queensland

The Paralympic Games, now a major global event, has a history rooted in rehabilitation.

The first official Paralympic Games was held in Rome in 1960. But its origins trace back to 1948, when neurologist Ludwig Guttmann organised the Stoke Mandeville Games in England for World War II veterans with spinal cord injuries. He believed sport could play a powerful role in rehabilitation, pushing the boundaries of human performance in ways other approaches could not.

Today’s Paralympic Games continue this legacy, with technology playing a central role in these achievements.

Technology has enabled athletes with disabilities to reach incredible heights. However, it has also introduced new challenges, particularly in ensuring fairness and equity in competition.

From simple to sophisticated

In the early days, Paralympic technology was basic by today’s standards. Athletes competed in regular wheelchairs and used simple strapping to assist.

As the Paralympic Games grew, competitive success became increasingly prized. As a result, athletes used specialised technology to gain a competitive edge.

Running blades, for example, are carbon fibre prosthetics designed to mimic natural leg movement while enhancing speed and bounciness. These blades have revolutionised track events. They enable athletes with lower-limb amputations to compete at speeds comparable to, and sometimes even faster than, able-bodied athletes.

South African sprinter and convicted murderer Oscar Pistorius was the first double amputee with running blades who competed in the London Olympics in 2012 as part of the men’s 4×400 relay.

A shifting conversation

By the end of the 2010s, however, the conversation about assistive technology used by athletes had shifted from celebrating integration to debating unfair advantage.

In 2019, Blake Leeper, a bilateral amputee sprinter, applied to World Athletics to compete in the 2020 Tokyo Olympics against able-bodied athletes. The international governing body for athletics received independent scientific advice that Leeper’s prosthetics gave him a competitive advantage and rejected the application.

Leeper contested this decision in the Court of Arbitration for Sport. But the court ruled against him.

Leeper, who is African-American, appealed the decision on the grounds the scientific advice provided to World Athletics was based on racially prejudiced science. But the court rejected his appeal. It ruled the evidence to be fair and unbiased.

As technology continues to advance, running blades may soon seem modest compared to what the future brings.

Neuroprosthetics are a notable example. These are devices that interface with the human nervous system to overcome losses in muscular strength and endurance that result from neurological impairments such as spinal cord injury.

The devices can be attached externally or surgically implanted. They can improve functions such as sitting stability and rowing machine performance.

It’s not hard to imagine some athletes using these devices to gain a significant – but possibly undetectable – advantage over competitors.

The International Paralympic Committee has a sport equipment policy. One of the principles is that sports performance should be determined primarily by human performance, and the effect of technology and equipment should be secondary.

However, upholding this principle requires enforceable rules. As technology advances, this will become increasingly challenging – just as it is in the Olympics.

Levelling the playing field

Technology can also play a crucial role when it comes to classifying athletes.

Each of the 22 Paralympic sports uses a classification system to ensure competition is fair and meaningful. Each athlete is classified according to the type and severity of their impairment.

However, classification is not without its challenges.

Despite significant research advances, the best and most valid processes available still rely on expert judgement. And even when classifiers follow strict guidelines, there is an incredibly wide array of test results for classifiers to consider.

Many classification tests also require athletes to give a full effort. This leaves open the possibility an athlete wishing to gain an unfair competitive advantage might deliberately underperform on these tests to exaggerate their impairment severity. They might then be placed in a class of athletes with more severe impairments.

To address these challenges, we are part of a research team that is currently developing an artificial intelligence-driven classification system.

We will use computer vision of para athletes performing a wide array of movements over time to train the system and develop an app. The app will allow athletes anywhere in the world to video themselves performing sports-related tasks, submit the video and receive an accurate, objective sports class.

This will make classifications more trustworthy and will improve access for athletes in rural and remote areas or developing countries.

However, the diversity of para athletes is enormous and the process of recruiting and filming a representative sample of high-level para athletes will not be easy. The system also can’t fully protect against athletes deliberately under-performing. But it is able to detect variations in performance that occur over time which would not otherwise be detectable to the human eye.

This will give greater confidence in the accuracy of the athlete’s classification.

Once the system is developed, its success will also depend on gaining the trust of the whole Paralympic community.

Using technology to gain an unfair advantage is as old as sport itself. But technology is also the very tool we must use to ensure fairness and to level the playing field.

John Cairney is currently working with an industry partner on developing an AI-driven method for athlete classification.

Emma Beckman is on secondment with the Queensland Academy of Sport and Paralympics Australia. She is currently working with an industry partner on developing an AI-driven method for athlete classification.

Sean Tweedy is currently working with an industry partner on developing an AI-driven method for athlete classification. He is also a member of the International Paralympic Committee’s Classification Compliance and Oversight Committee and a member of World Para Athletics Classification Advisory Group.

What is eastern equine encephalitis? Two mosquito researchers explain what’s behind the latest outbreaks

Source: The Conversation (Au and NZ) – By Cameron Webb, Clinical Associate Professor and Principal Hospital Scientist, University of Sydney

Health authorities in the United States are issuing warnings and closing public parks due to a rare but potentially deadly mosquito-borne disease.

This week, a resident of the US state of New Hampshire died after being hospitalised with eastern equine encephalitis. Cases have also been detected in other states.

But what is eastern equine encephalitis? How is it spread? What, as the name suggests, do horses have to do with it? And is it a problem for Australia?

What is eastern equine encephalitis?

Eastern equine encephalitis is caused by a virus typically only found in some eastern parts of the Americas, from Central America to Canada.

Eastern equine encephalitis virus causes neurological disease, particularly encephalitis (inflammation and swelling of the brain) and is transmitted to humans via a mosquito bite. Symptoms can be severe and potentially fatal.

But most people bitten by a mosquito carrying the virus won’t have symptoms. For those who develop disease, symptoms include headache, neck stiffness, confusion, seizures and coma.

About one-third of patients with severe symptoms will die and many of those who survive have ongoing neurological problems.

It’s not just people at risk from the virus. Horses are susceptible too and, like humans, can also develop fatal encephalitis after a bite from an infected mosquito.

The virus was discovered after an outbreak of fatal disease in horses in the New England region of the US in 1831, hence the reference to equine illness in its name.

Wild, farmed and captive birds can also be infected with the virus and, in some species develop disease. In fact, birds are key to how the virus spreads.

How is eastern equine encephalitis virus spread?

Birds – especially passerines, a group that includes robins, starlings, thrushes and blue jays – are the main hosts of the virus.

These birds produce high enough levels of the virus to infect biting mosquitoes and maintain what’s known as a “transmission cycle”.

Bird-feeding mosquitoes in forested wetlands, especially Culiseta melanura, allow the virus to circulate among birds. But this mosquito rarely bites people so it isn’t as important for outbreaks of human disease.

It’s the mosquitoes that feed on both birds and mammals that transmit the virus to humans and horses. These include Aedes, Coquillettidia and Culex mosquitoes. But once infected, humans and horses do not spread the virus. That’s because they don’t produce high enough levels of the virus to infect mosquitoes.

How can we limit the spread?

There are no specific treatments for infection with eastern equine encephalitis virus, or any licensed vaccines for use in people. There is a vaccine registered for veterinary use to prevent virus infection in horses.

Personal protective measures and mosquito control are the main strategies to limit people being exposed to the virus.

Outbreaks can have a significant impact on communities, not only from the disease itself, but from measures implemented to limit transmission.

Recent outbreaks have led to outdoor events being cancelled. There have also been concerns about the widespread use of aerial “fogging” to kill mosquitoes as commonly used chemicals are not specific to mosquitoes and may pose a risk to other insects.

Some towns have closed parklands during the evening and asked residents not to go outside at night.

Why is there an outbreak now?

The virus circulates year-round in tropical areas such as Florida. In the north-east of the US, the virus has more sporadic activity. Here, it’s typically introduced by migratory birds and is active in the warmer months when mosquito populations are thriving.

The virus has been known for many decades and a number of outbreaks have been reported in North America. One of the last substantial outbreaks was in 2019 across several north-eastern US states, when there were 38 human cases (including 12 deaths).

There is evidence the virus is spreading into new regions of North America. But, given the sporadic nature of outbreaks, it is difficult to predict when they will occur.

A number of factors are likely at play in determining future outbreaks and the spread of the virus to new regions, including the climate, environmental factors, the activity of mosquitoes and wildlife, and also, importantly, people.

With increasing contact between people and the mosquitoes that can pass on the virus from infected birds, the public health risks increase.

Perhaps human activity around the habitats of mosquitoes and birds, including encroachment of urban development into forested wetlands, elevates risk.

So it’s crucial for health authorities to monitor mosquito and virus activity to provide early warning of the risk of human disease.

Is there a risk to Australia?

There is no evidence that eastern equine encephalitis virus is in Australia and there is no immediate risk of its introduction here.

While Culiseta mosquitoes are found in Australia, their role in local virus outbreaks in people or animals is not well understood.

But there are dozens of different mosquitoes involved in the spread of alphaviruses in Australia. That’s the group that includes eastern equine encephalitis virus, as well as ones that exist in Australia, namely Ross River and Barmah Forest viruses.

It’s reasonable to assume some of these mosquitoes may be able to transmit the virus but this hasn’t been tested in laboratory experiments.

There is very little information on how local passerine birds may play a role in establishing cycles of viral transmission in Australia. There is also no information on whether native Australian vertebrates, such as marsupials, would respond to infection.

When we consider all the available evidence, the risk of the virus spreading to Australia and subsequently causing an outbreak is, most likely, very low.

Are travellers at risk?

The risk of being bitten by a mosquito carrying eastern equine encephalitis virus is extremely low. But anyone visiting eastern regions of North America, including the US and Canada, where the virus can occur should take precautions to avoid being bitten by mosquitoes.

Follow directions from local health authorities. And take steps to avoid the locations (especially forested wetlands) and times when mosquitoes are active (typically dawn and dusk). Wear loose fitting clothing with long sleeves and apply repellents containing diethyltoluamide (commonly known as DEET), picaridin or oil of lemon eucalyptus.

These precautions will also protect against infection with other mosquito-borne viruses you might encounter there, such as West Nile virus.

The Paralympics can be an economic boon for host cities – and leave a unique legacy

Source: The Conversation (Au and NZ) – By Kirsten Holmes, Professor, School of Management and Marketing, Curtin University

The mega-event glow continues in Paris, with the 2024 Summer Paralympic Games now well underway. Some 4,400 athletes will take to the world stage to compete across 22 different sports.

The Paris Paralympic Games have attracted a phenomenal level of interest – over two million tickets have now been sold. Some are now speculating the event could make Paralympic history and become the first-ever sellout.

This raises some important questions for host cities. How do the economics of the Paralympics compare to the Olympics? Who gets the broadcast rights?

Above all, what is the legacy of this event on its own – separate from the Olympics – likely to be for Paris? The games will provide an anticipated economic boon, but their real value lies in the ever-brighter spotlight they shine on elite para sports.

The games are deeply intertwined

The cost of hosting the Olympics can famously blow out to way above initial estimates. Since the early 2000s, host cities have been awarded the rights to stage the Paralympics as well, which means the economics of both – and risk of cost overruns – are closely intertwined.

A recent University of Oxford report suggested the combined cost of the Paris 2024 games – A$12.8 billion – represented a cost overrun of about 115%.

Long-running concerns about cost blowouts spurred the International Olympic Committee (IOC) to create the “New Norm” model, approved in 2018, which featured 118 reforms aimed at reducing the financial burden of hosting the games.

The Paris games have actively adopted several elements of this model. Some of these initiatives – which remain in place for the Paralympics – include using existing infrastructure and attractions where possible and the extensive use of temporary venues.

The Paris Paralympic village has been designed to be 100% accessible, reusing much of the infrastructure from the Olympics.

As the Paralympic games feature sports distinct from the Olympics, a range of venues have been repurposed, such as the volleyball venue at the Eiffel Tower, which will host the blind football.

Making Paris more accessible for everyone

Paris has taken a range of steps to make the city more accessible, expecting about 350,000 visitors with disabilities to attend the games.

This has included repairing damaged roads, improving road crossings by lowering sidewalks and installing new warning strips and traffic light sounds.

The city also spent €22 million (A$35.8 million) on making 59 of its 61 bus lines fully accessible.

The cost of making these infrastructure improvements can be heightened by the need to implement them quickly.

But for Paris, they will undoubtedly provide long-term benefits to city users and future visitors as a structural legacy of the 2024 Paralympics.

A tourism boost?

Hosting the Olympic and Paralympic games can quickly thrust a city into the international spotlight. The resulting tourism boom is sold as one of the biggest benefits of hosting the games.

Just how much Paris will benefit from this exposure has been an obvious point of debate, given France is already the world’s most visited country by international tourists.

Working out how the Paralympics’ specific effect on tourism might compare to the Olympics is difficult. But we can look to previous games.

A survey of visitor groups to the 2014 Winter Olympic Games in Sochi found a notable difference in average daily tourist spend between visitors to the Olympics (A$381) and visitors to the Paralympics (A$281). This was due to higher ticket and transport costs for Olympic visitors.

But tourists visiting the Paralympics stayed in the destination longer, which meant that total spending was similar for both groups.

Both groups were motivated a little differently as well. Olympic tourists were more focused on the competition, whereas Paralympic tourists were more inclined to seek out the festival atmosphere the games bought to the destination.

What about the broadcast rights?

For the first time in history, the Paris games will offer live coverage of all 22 Paralympic sports through a record number of global media partners. But they aren’t automatically included in the rights to broadcast the Olympics.

In Australia, Channel Nine paid the IOC A$305 million for the exclusive rights to Olympic Games coverage from 2024 through to 2032. Separately, it also negotiated with Paralympics Australia to secure the media rights for the 2024 Paralympic Games.

The dollar figure for this second deal is not publicly available, but is likely lower than the cost of the Olympics coverage, with fewer Paralympic sports to showcase.

Both deals have already proved lucrative for the network. In early August, Nine had secured more than A$140 million in advertising revenue for its Olympic and Paralympic coverage.

Where the real value lies

Beyond economic considerations, many would argue the real value of hosting the Paralympics is in the opportunity to shine a spotlight on elite para sports.

Some past media representation of the Paralympics has been problematic, with a focus on athletes’ disabilities as opposed to their performance.

With the record levels of media coverage for Paris 2024, the International Paralympic Committee has launched a major social media campaign to emphasise that para athletes are not “participating” but “competing” in the games.

We now hope that cities like Brisbane – set to host the games in 2032 – can learn from Paris in improving accessibility city-wide, and avoid some of the historical cost overruns of previous Olympic and Paralympic games.

US conservative Candace Owens is set to tour Australia. Can the government stop her?

American conservative author and influencer Candace Owens has amassed millions of followers on YouTube and X for her controversial views. These include suggesting the Holocaust was “ethnic cleansing that almost took place”. She also recently said men are being “socially engineered to be gay” and rejected that people can be transgender.

Owens is due to deliver talks in five cities across Australia in November 2024. But Australian Jewish groups and others are calling on Immigration Minister Tony Burke to deny her an entry visa. In the United States, the Anti-Defamation League has also previously outlined its concerns about her antisemitic messaging.

In response, Owens’ promoters have said she’s “never incited violence or been cancelled by social media for breaching community standard, and everything she has said has been in her capacity as a commentator and as an author”.

While it’s unclear if Owens has applied for a visa yet, what can the federal government do in cases like these?

It’s up to the minister

Australia’s federal government has discretion over which non-citizens can enter the country. Other than the specific rights of those seeking protection under international law, the capacity of a non-citizen to enter Australia is a privilege, not a right.

This is not a new issue. Australia has previously banned conspiracy theorists and far-right figures from entering the country. It’s also not exclusive to Australia, with other countries facing similar decisions.

In addition to decisions the department can make about granting visas, the immigration minister has the overarching discretion to decline or approve visas on character grounds.

Decisions of departments to grant or decline a visa can be reviewed by tribunal and courts. However, exercises of ministerial discretion to decline, cancel or grant visas are not reviewable. In short, Owens cannot seek judicial review of a decision of the minister to decline her a visa, should that happen.

On what grounds?

There are several grounds on which a minister can decline a visa. These include someone’s criminal record, concerns in relation to domestic violence, or concerns about terrorist activity. Overall, the minister is to consider the best interests of the Australian community.

In addition, and relevant to the case of Owens, another factor the minister can consider is the risk of vilification of a segment of the community, including conduct likely to be incompatible with the smooth operation of a multicultural society.

There are reports of a marked rise in antisemitic and Islamophobic incidents in Australia since October 2023.

In that context, it is reasonable to be concerned that someone with a history of antisemitism, for example, may contribute to a destabilisation of our social cohesion at a time when we need to be protecting it.

Threats to social cohesion are national security risks for many reasons, not least because this can lead to the normalisation of provocative and inflammatory behaviour. In turn, this has the potential to trigger an increase in acts of politically motivated violence, including terrorism.

In short, how we get along with each other in public matters in minimising the risk of extremists feeling emboldened to attack other members of our community violently. How we speak about each other in a public forum matters for minimising radicalisation. The Australia Security Intelligence Organisation (ASIO) has warned of this.

What about free speech?

As noted above, while Owens can appeal a decision on a visa made by the department, a court or tribunal cannot review an act of ministerial discretion.

However, ministers are not always immune to political pressure and decisions to cancel visas of high profile would-be visitors are not without public controversy.

Often this controversy centres on a difference of opinion on where the outer boundaries of the principles of free speech begin and end. Who gets to decide those boundaries?

A marketplace of free-flowing ideas is an important element of a representative democracy. There are also times when allowing for the airing of problematic ideas allows for them to be refuted in a way that is edifying for the community.

However, the right to free speech is not absolute, because it has to accommodate other rights. In an era of misinformation and disinformation and the rise of extremist ideas propagated online, the principles of free speech must be balanced alongside the imperative to keep our communities safe.

There is also a need to protect the right of all members of our community to be free from racial vilification, for example.

Importantly, there is no absolute right to free speech in the Australian Constitution. However, the Constitution does contain an “implied freedom of political communication”.

That freedom can be burdened for legitimate purposes as long as the measures taken are proportionate to the risk. Regulating hate speech is an example of a legitimate public purpose.

The means by which lawmakers can achieve that purpose that are not unlimited, but as long as regulation remains proportionate, limitations of political communication are permitted by the Australian Constitution.

The big picture

Ministerial discretion is an important tool in visa decision-making, but it is open to abuse.

Ultimately, though, there are checks and balances because ministers are accountable to the parliament (and to the National Anti-Corruption Commission). And parliament is accountable to the electorate.

But more broadly, words have power, particularly in the public domain. With great power comes great responsibility. That includes minimising hate.

Wondering how to get from Brisbane to Melbourne without wrecking the climate? Our transport choices make a huge difference

Source: The Conversation (Au and NZ) – By Robin Smit, Adjunct Professor, School of Civil and Environmental Engineering, University of Technology Sydney

Australian transport emissions are still growing. As a result, transport is expected to be our biggest-emitting sector by 2030. So, cutting transport emissions is crucial to Australia’s net-zero strategy.

Studies show electrifying passenger vehicles and trucks will greatly reduce greenhouse gas emissions. But the switch to electric vehicles is slow. It won’t be enough to reach net-zero by 2050.

Other strategies are needed. That’s where the concept of “mode shift” comes in. It involves shifting passengers and freight to lower-emission forms of transport such as electric rail and shipping.

In two new research papers, a colleague and I show what a big impact this could have on Australia’s emissions. We used the Inland Rail project linking Brisbane and Melbourne as a case study of the potential impacts of shifts between land-based transport, shipping and aviation. (The route comprises 12 sections, some already operational, some being built and others in the planning phase.) We modelled the total emissions of these modes for three years: 2019, 2030 and 2050.

We found electric rail is hands down the land transport mode with the lowest emissions intensity (the amount of greenhouse gas produced per kilometre travelled) for both passengers and freight. When we included air and sea transport, we found electric rail and shipping have the lowest emissions. Air transport in Australia is in a class of its own as its emissions performance is so much worse than other modes, particularly for freight.

It will be very hard to reach zero emissions in the transport sector in a timely fashion. To get there will require all hands on deck for the freight sector but also for personal travel and the choices we make.

We compared land transport options for getting to net zero. Hands down, electric rail is the best


How much difference can mode shifts make?

Current domestic emissions by transport mode are skewed. The vast bulk (85%) of total annual carbon-dioxide-equivalent (CO₂-e) emissions comes from road transport. It’s followed by air (8%), rail (4%) and sea (2%) transport.

To fairly assess performance, we used the well-to-wheel/wake approach. It includes both direct and indirect emissions from producing, distributing and using fossil fuels, hydrogen and electricity. We calculated these emissions for 2019, 2030 and 2050.

These figures do not yet include non-domestic emissions created by Australian aviation and shipping activities overseas. Including these will greatly increase total emissions from these modes.

For passengers, air transport had the highest emission intensity. It is an energy-intensive mode of transport and has climate effects in addition to those caused by its CO₂ emissions, as I outline below. Including these effects, we estimated air transport’s emission intensity to be 1.7 to 2.8 times higher than for road transport.

From an emissions perspective, high-speed electric rail is a great alternative to road and air transport for travel between capital cities. It would result in deep emission cuts varying from 75–95%.

For freight in 2019, ships performed much better than any other mode. This included electric rail, due to the relatively high emission intensity of grid electricity at the time. As renewable sources replace fossil fuel generation, electric rail’s emission intensity will improve.

By 2050, bulk carriers and electric rail were estimated to have the lowest emission intensity of all modes. Shifting freight to these modes would deliver deep emission cuts varying from 50–99%.

Air transport performed particularly poorly for moving freight. Its emissions intensity was, on average, 96 to 265 times higher (including the non-CO₂ climate effects of aircraft) than that of electric rail, for instance.

Please NOTE that aircraft are not included due to the impact of its high emissions on chart readability.

How did the study reach these conclusions?

Modelling the impacts of transport mode shifts on emissions is complex, country-specific and changes over time. It involves a broad range of inputs and information. Each mode has its own challenges and specific details to be considered.

For instance, aviation and shipping operate in the air and water. This means the modelling must account for winds and currents.

As another example, the practice of “slow steaming” – when cargo ships reduce their speed to cut fuel use and emissions – was considered for shipping.

For aircraft, there are additional net radiative forcing effects. (Radiative forcing is a measure of the influence a climatic factor has on the radiant energy impacting Earth’s surface.) These effects are complex and include the formation of contrails (condensation trails), aircraft-induced clouds and ozone formation (secondary air pollutant).

The analysis was based on statistical modelling. That is, instead of estimating single emission values, we quantified the most likely value and a plausible range in emissions performance.

It is also very important that the estimates reflect Australian conditions. For instance, we specifically modelled emissions from ship types and sizes (bulk carrier and container ships) and aircraft (A320 and B737) commonly used in Australia.

The modelling included mode-specific aspects such as vehicle weight and capacity, passenger occupancy, payload, annual passenger and freight volumes, operational profiles, future efficiency improvements and travel distance.

Travel distance can be surprisingly different between modes, as the map below shows. Air transport generally has the smallest travel distance. Sea transport routes can be much longer (about 60%).

What does this mean for policy and people?

Mode shift from road and air to rail and shipping has unused potential in Australia. Our findings suggests governments should, where possible, promote this shift for environmental and climate change reasons.

Clearly, other aspects such as costs and practical barriers need to be considered. But, from an emissions perspective, mode shift could get the Australian transport sector much closer to net zero.

And, as individuals, we can often reduce our own impacts by choosing not to travel or using lower-emission transport modes for our personal travel and the products we buy.

Harris’ win probability falls slightly after Democratic convention and Kennedy withdrawal

Source: The Conversation (Au and NZ) – By Adrian Beaumont, Election Analyst (Psephologist) at The Conversation; and Honorary Associate, School of Mathematics and Statistics, The University of Melbourne

The United States presidential election will be held on November 5. In analyst Nate Silver’s aggregate of national polls, Democrat Kamala Harris leads Republican Donald Trump by 48.8–45.0. In my previous US politics article last Sunday, Harris led Trump by 48.8–44.8.

Joe Biden’s final position before his withdrawal as Democratic candidate on July 21 was a national poll deficit against Trump of 45.2–41.2. By the election, Biden will be almost 82, Trump is now 78 and Harris will be 60.

There were two developments last week that potentially changed the polls. First, the Democratic National Convention was held from August 19–22. Second, Robert F. Kennedy Jr withdrew from the presidential contest and endorsed Trump on August 23. When he withdrew, Kennedy had only about 4% support in national polls.

The next event that could potentially change the race is the September 10 debate between Harris and Trump. The June 27 debate between Biden and Trump eventually led to Biden’s withdrawal.

Pennsylvania a problem for Harris

The US president isn’t elected by the national popular vote, but by the Electoral College, in which each state receives electoral votes equal to its federal House seats (population based) and senators (always two). Almost all states award their electoral votes as winner takes all, and it takes 270 electoral votes to win (out of 538 total).

In Silver’s model, Harris’ chance of winning the Electoral College has fallen from 53.2% last Sunday to 47.3%, with Trump now the favourite to win at 52.4% probability. Harris’ win probability peaked on August 14 at 57%. This is the first time Trump has been favoured to win since August 3.

The Electoral College is biased towards Trump relative to the national popular vote. In Silver’s model, Harris needs to win the popular vote by at least two points to be the Electoral College favourite.

A key reason for Harris’ drop is Pennsylvania, which has 19 electoral votes, the most of any of the swing states. If either Harris or Trump wins Pennsylvania, that candidate has about a 92% chance to win the Electoral College.

Silver wrote that recent polls in Pennsylvania have been weak for Harris, although his model does not yet include a Morning Consult poll that gave Harris a four-point lead in Pennsylvania.

I previously wrote that, from the point of view of maximising her chances to win the Electoral College, Harris should have selected Pennsylvania Governor Josh Shapiro as her running mate instead of Minnesota Governor Tim Walz. Democrats could regret this choice.

Another factor that is hurting Harris is the model’s convention bounce adjustment. Convention bounces usually peak a week after the convention, then fade in the next few weeks. I previously wrote that Harris needed to be leading by four to five points nationally in polls conducted after the Democratic convention to maintain her win probability.

Harris’ national lead of 3.8 points is just below the lower bound where she would maintain her win probability. If her national lead is unchanged in the next two weeks, her win probability will increase again. But the model expects Harris’ lead to drop in the next two weeks.

Further analysis

It’s possible that Kennedy’s withdrawal and endorsement of Trump has changed some of his voters into Trump voters. In most polls before Kennedy’s withdrawal, Harris benefited from his inclusion compared with a Harris vs Trump head to head version.

The initial surge for Harris was probably driven by relief at Biden’s withdrawal. Biden now has a net approval of -12.9 in the FiveThirtyEight aggregate, an improvement from -17.1 when he withdrew on July 21. But his unpopularity is still likely to hurt Harris, who is campaigning on a continuation of Biden’s policies.

After large gains in Harris’ net favourability in the first two weeks of her candidacy, her net favourability gains have stalled. Harris’ net favourability in the FiveThirtyEight tracker is -1.4, up from -16.0 on July 20, but a much smaller improvement from -3.9 on August 14.

I believe Harris’ honeymoon from replacing Biden is over, and it will be harder for her to make gains in polls now.

Trump’s net favourability has dropped back to -9.2 after gaining some ground following the mid-July Republican convention. Trump’s running mate JD Vance is at -9.8 net favourable, while Walz is at +4.8.

The balance battle: 5 reasons why dads are struggling with workplace flexibility

Source: The Conversation (Au and NZ) – By Alina Ewald, Associate Lecturer in Psychological Sciences, Western Sydney University

Natee Meepian/Shutterstock

Despite a rise in dual-earner families in Australia and men wanting to be more engaged with their kids, there are still major hurdles preventing dads from fully embracing formalised flexible working arrangements such as part-time work or parental leave.

This is a problem because we know if dads achieve work-family balance it benefits children, women’s employment and men’s wellbeing.

So why are dads finding it so challenging to adopt formal flexible working arrangements to help them as a parent?

As a fathering researcher focusing on mens’ adoption of flexibility, I have identified five main reasons.

Work-family balance barriers

1. Flexibility is often feminised

Flexibility can be associated with the “mummy career track”.

Modifying work after becoming a parent is positioned as being for women with children – rather than for dads.

When men do adopt flexibility for caring, some experience a backlash in the form of stigmatisation or discrimination, especially in relation to parental leave and returning to work – even when they take short periods of leave.

In fact, the Australian Human Rights Commission found men were twice as likely to have their leave requests rejected than women.

Recent Australian data show only 8% of organisations set targets for men’s engagement with flexible working.

This issue is driven by deep-seated gender norms and stereotypes about work and care and it results in men often being left out of the flexibility conversation.

2. There is an expectation for men to focus on their career

Men’s caring responsibilities are largely invisible in the workplace and
dads often get the message to prioritise career development and financial provision over being actively involved in their children’s daily care.

In relation to this, men report a lack of workplace acceptance for flexible working arrangements and a concern regarding the career penalties that could follow.

While the benefits of dads being more hands-on as a parent are clear – including positive outcomes for child development, for father-child bonding, and for men’s wellbeing – negative career implications are often cited as a prominent downside associated with some forms of flexibility.

Underpinning the expectation for men to be dedicated to their careers are masculine norms and the work devotion schema (a moral obligation to dedicate oneself to work).

However, Australian research shows men want more flexibility and some are even willing to change their job to achieve this.

Many fathers are trying to work more flexibly to benefit their family lives.

3. Men don’t know what they are entitled to

There is sometimes a lack of awareness from men and a lack of resources from employers surrounding what men are entitled to.

Many dads aren’t fully aware of the work-family policies available to them or where to look. They are sometimes reluctant to ask employers directly due to a perceived lack of entitlement or fears around negative judgement.

As a result, when it comes to finding out about flexibility, men often have to dig around on their own to figure out what they are actually able to use.

The lack of readily available information for men reinforces the message that flexibility for parenting is not really designed for dads.

To help overcome this issue, organisations should ensure they have conversations with fathers, and not just with mothers, about adjusting their work schedules when they have children.

4. Occupational barriers

Men in different positions within organisations face distinct challenges when attempting to adopt flexible caregiving arrangements.

Those in high-status roles such as senior workers or managers have a lot of control over their work hours but they are often reluctant to adopt formal flexibility for caring due to concerns it may signify a lack of commitment to work.

In contrast, men working in lower-status roles report a lack of power to request flexibility and some report having requests denied or being pressured to not access flexibility options.

5. A lack of male role models

There is a lack of role-modelling from other men and a lack of spaces for men to learn from each other about working flexibly.

Men also report being hesitant about using flexible work arrangements because they don’t see their leaders embracing or setting an example themselves. This leads to concerns it could result in negative outcomes, leading to missed promotions or career opportunities.

Having more male leaders working flexibly for family reasons would set an example for other men but barriers exist due to expectations from some leaders to be present at work.

Where to from here?

In order for things to change, men’s caregiving roles must become more visible at work and organisations must better support dads in adopting flexibility for caring purposes.

Some effective ways to improve the situation include having male leaders model flexibility, organisations promoting the idea that flexibility is for dads too and telling men about their work-family entitlements when they become, or are about to become, a father.

Computer ‘reconstructions’ of faces from ancient times are popular. But how reliable are they?

Source: The Conversation (Au and NZ) – By Konstantine Panegyres, McKenzie Postdoctoral Fellow, researching Greco-Roman antiquity, The University of Melbourne

When we read about the lives of people from the ancient past, we naturally want to know what they looked like.

But how do we find this out?

In recent years, computer-assisted reconstructions of the faces of famous figures from the Greco-Roman world have become popular.

In 2020, for example, a digital artist went viral for using artificial intelligence (AI) technology on the busts of Roman emperors to recreate their faces in a photo-realistic way.

How are facial reconstructions done?

The simplest form of facial reconstruction involves adding realistic-looking skin, eyes and hair to Greek or Roman busts. Other methods can be more complicated.

One of the most famous facial reconstructions of any individual from the Greco-Roman world was the case of Hermione Grammatike. Hermione was a teacher in her 20s who died in Egypt in the early 1st century CE.

Hermione’s ancient portrait and skeleton both survived with her mummy. So, any attempt to reconstruct her face on the basis of the skeletal remains could be compared with the portrait of her.

In 1997, British Museum researchers used CT (computed tomography) scans to create a 3D image of Hermione’s face.

After reconstructing the surface of the face using the skull, the researchers then consulted the coffin portrait to nuance the details.

In spite of this rigorous combination of methods, they acknowledged difficulties:

Since the skull does not carry enough information to completely determine the facial surface, facial reconstruction from skulls will always contain an element of art. The reconstructed face is likely to resemble that of the living person but is very unlikely to be an exact replica.

So, even with careful techniques, there still remain some doubts about facial reconstruction.

But such reconstructions are becoming more accurate. This is largely thanks to new methods of DNA extraction and analysis, which make it possible to work out the correct colours of people’s hair, skin and eyes.

How reliable were ancient portraits of people?

Basing reconstructions of people’s faces on their surviving busts or portraits is not an entirely safe procedure.

In some cases, there are discrepancies between ancient portraits of people and ancient literary descriptions of what they looked like.

For example, according to ancient texts, the philosopher Aristotle was bald or (alternatively) had short hair and a short beard, as well as small eyes. He wore rings on his fingers and luxurious clothes.

However, ancient busts that have been identified as depicting Aristotle show him with a full beard and plenty of hair.

This raises a new problem: which pieces of information are more reliable – the ancient artwork or the ancient literary description? In cases such as these, it seems almost impossible to decide.

But some ancient portraits must have been fairly accurate depictions of their subjects.

A Greek poem from the 1st century CE describes a boxer who became so disfigured by his sporting profession, he no longer resembled his official portrait. In a dispute over their father’s inheritance, the boxer’s brother showed the boxer’s portrait in a court of law and successfully claimed the boxer was not actually his brother – thus denying his inheritance. This case shows some ancient portraits must have been accurate enough to even be used as a sort of legal proof of identity.

Other authors indicate portraits were not always made solely for accuracy. The Roman writer Claudius Aelianus informs us that

in Thebes a law was in force which instructed artists – both painters and sculptors – to make their portraits flattering. As punishment for those who produced a sculpture or painting less attractive than the original the law threatened a fine of a thousand drachmae.

The wish to see historic faces is universal

In around 39 BCE, the Roman scholar Marcus Terentius Varro published a collection of famous people’s portraits, “not allowing their likenesses to disappear or the lapse of ages to prevail against immortality in men”.

Varro’s collection apparently included 700 portraits of famous historical Greek and Roman people, and each portrait was accompanied by an epigram and brief biography. This collection must have satisfied the wish of the public to know what the faces of famous people looked like.

Clearly, ancient and modern people share this fascination.

We can surely enjoy reconstructions of the faces of people from ancient times. We just need to keep in mind two important issues.

Firstly, ancient portraits and busts were themselves not always reliable depictions of people, so reconstructions based on them are of uncertain accuracy.

Secondly, modern researchers acknowledge that reconstructions based on skulls have limitations, though the accuracy of this method is rapidly improving.

So, the next time you see a reconstruction of some ancient person’s face, be cautious before thinking that you are really looking at the exact, almost photographic likeness of someone from the past. You might be – or you might not.

Lower speeds on local streets cut deaths and injuries by a quarter in Wales. Over 100 experts want Australia to do the same

Source: The Conversation (Au and NZ) – By Jennifer L. Kent, Senior Research Fellow in Urbanism, University of Sydney

The Bureau of Infrastructure, Transport and Research Economics (BITRE) has released its latest road deaths bulletin. The results are terrifying.

Each month, someone at the bureau has the bleak task of contacting state police to determine how many people have been killed on our roads. If the bureau had a tendency to shoot its messengers (and I’m not saying it does), this month’s courier would have tabled the stats and quickly ducked for cover.

In July, 124 people died on Australian roads. This toll was 31.6% higher than the July average for the past five years. In July 2024, 40 more people died on our roads than in July 2019. That’s 40 daughters, sons, brothers, sisters, mothers and fathers.

The July figures were not a monthly blip. The 1,327 lives lost in the year ending July 2024 marked a 10.2% increase from the preceding 12 months. It was the worst 12-month toll since 2012.

And for every death, an estimated 20 people are hospitalised for serious road trauma. These numbers are not only shocking, they are shameful. More than 100 of Australia’s top transport and urban researchers have now signed an open letter calling for lower speed limits on local streets. The evidence they cite from overseas is clear: lower speed limits will save lives.

Why is the road toll rising?

Road casualties are on the increase for multiple reasons.

The most obvious one is the bigger cars we are driving. Our large SUVs and twin-cab utes are much safer – but only if you’re on the inside. Their sheer mass can make a mess of any vulnerable human flesh that gets in their way.

Which brings me to the real tragedy here: we know exactly what to do to reverse this trend; we just don’t have the political will to do it.

You see, road trauma is actually a straightforward matter of physics. The embedded kinetic energy in a moving vehicle is released on impact – whether it be with a street sign, tree or child. The faster a vehicle is travelling and the greater its mass, the more energy is released. And it’s the energy that kills – either as it’s dispersed through a vehicle or through someone’s body.

This means that if a child is hit by a car doing 50km/hour, there is a 90% chance that child will die. But if that car is doing 30km/h, the child has a 90% chance of living. Yes, it is simple physics, with devastating implications when ignored.

Speed is the key to reducing road trauma. Yet here in Australia we maintain the third-highest default local speed limit in the OECD. In most Australian states, the limit is 50 kilometres per hour (km/h). That’s well above the World Health Organization’s recommended 30km/h wherever cars and vulnerable road users interact.

We have tinkered around the edges with slower speeds in school zones and areas with particularly high numbers of pedestrians. Some forward-thinking local councils have reduced speed limits across their area, usually to 40km/h. But we know the real gains come when speeds of 30km/h are applied not just in specific locales, but across the entire local road network. Just ask Wales…

Welsh experience is compelling

In September 2023, Wales decreased the default speed limit for local roads to 20 miles per hour (roughly equivalent to 30km/h). As a result, this new speed limit applied to the vast majority of these roads, whereas before the change the vast majority had a 30mph (50km/h) limit.

The politician responsible for this change, Lee Waters, has been touring Australia this month, speaking about this and other game-changing sustainability and wellbeing legislation enacted on his watch. His courage in pushing this unpopular move through paid off. In just three months, the casualties (combined death and serious injury rates) on local roads in Wales dropped by 26% to 377, from 510 in the same period for the previous year.

What’s also notable about the Welsh experience is that, in terms of the blockbuster budgets typical of road projects, it hardly cost a penny. Authorities simply educated the public and changed the road signs. There wasn’t even much legal enforcement.

Instead, the public responded to the message and started driving more slowly. While it’s not quite as slow as the Welsh government’s ultimate aim, it’s a good start. Because it’s slow enough to save lives.

So what’s stopping Australia?

This is very different to the story in Australia. Here, our policies and politics imply that the only way to slow cars is to radically redesign our roads. Apparently, we need to make our streets “intuitively” slow by narrowing them and putting in speed humps.

This kind of intervention needs funding – which is currently tied up in more politically palatable programs of road building and maintenance. As a result, our vehicle speeds remain fast – and fatal.

But Wales has clearly shown that streets can be slowed by reducing the posted speed limit, backed up by community education and strategic enforcement. Of course, road safety infrastructure is also needed, but while we wait for it to be funded and constructed, road trauma continues to tear people’s lives apart.

Coinciding with Lee Waters’ visit to Australia, the open letter from more than 100 academic experts concludes:

The urgency of the epidemic of road trauma in Australia demands a more proactive and timely response, and political leaders are at the helm of change. The evidence is unequivocal that Australian lives are in your hands. Please, slow speeds on local streets.

Angry, wise, or plain horny? Zeus comes in many forms onscreen – just as he did in the original myths

Netflix

With a flash of garish colour and the blaring of an ’80s rock track we are on Mount Olympus, home to the pantheon of ancient Greek gods and goddesses.

But its not the Mount Olympus you’d normally think of. It’s an opulent house with large-screen TVs and gold watches. Overseeing it all is mighty Zeus, the king of the gods, played by Jeff Goldblum.

Netflix’s new six-part series, KAOS, is a brilliant reimagining of classical mythology for the 21st century. Created by Charlie Covell, writer on The End of the F***ing World (2017–19), the series follows six humans who learn they are part of a larger prophecy – their fates at the mercy and whims of the Olympian gods.

Narrated by Prometheus (Stephen Dillane), the series is darkly comedic in its exploration of themes from the original myths, such as power and abuse, gender politics and life after death.

Goldblum’s take on Zeus is mercurial. Powerful, but petulant and selfish, his Zeus is insecure. It’s a fascinating take on the god. “My character is complicated and charismatic, not to mention cruel,” the actor revealed in an interview.

The ancient Greeks themselves were ambiguous about Zeus. He could be a fearful figure or a humorous one. He ended up with dozens of epithets, ranging from Areius (“warlike”) to Zygius (“presider over marriage”), and most commonly Olympios and Panhellenios to signify his divine power over gods and humans alike.

Hollywood has similarly found a variety of ways to present Zeus, but usually in supporting roles (unlike in KAOS, where Zeus takes centre stage). In fact, one early cinematic appearance of the god was at the birth of filmmaking itself, in Georges Méliès’ silent film Jupiter’s Thunderballs (1903).

Zeus the powerful and vengeful god

Zeus (and his Roman equivalent Jupiter) was the god of sky and thunder in the Greek pantheon on Mount Olympus, and the father of many heroes and demigods of classical mythology. His main visual attribute was the lightning bolt, which is hinted at cleverly in a number of scenes in Goldblum’s performance.

The most common portrayal of Zeus in film and television is that of a vengeful and wrathful god who interferes with and manipulates the activities of others.

In Clash of the Titans (1981), a retelling of the myth of Perseus, Zeus (Laurence Olivier) manipulates the gods to support Perseus.

And this continues in the 2010 remake and its sequel, Wrath of the Titans (2012), in which Zeus (Liam Neeson) is an active participant in a plot centred on the struggle against Hades.

In the film Immortals (2011), although Zeus is often detached from the plot and merely observes, he is ultimately roused to action by anger.

Similarly, in the Percy Jackson films and TV series (based on Rick Riordan’s books), Zeus is characterised by his anger directed at Percy as he accuses him of stealing his lightning bolt.

Zeus the lustful abuser

Zeus was, well… there is no other way of saying it… horny. Incredibly horny. Despite the long-suffering protestations of his wife (and sister), Hera, Zeus would go on to father innumerable gods and demigods in the original myths.

His affairs with both divine and mortal women were almost always non-consensual and always ended badly for the seduced woman, who would either immediately die upon seeing Zeus in divine form or suffer the inventive vengeance of Hera. As Susie Donkin explained in the title of her 2020 book: Zeus is a Dick.

Unlike many filmed portrayals of Zeus, KAOS does not shy away from this aspect of his behaviour. But it is perhaps best represented in the adult animated series Blood of Zeus (2020-), in which much of the plot is driven by the aftermath of Zeus’ sexual proclivities.

Zeus the father figure

Hercules (Herakles in Greek) is one of the most filmed characters of all time, so the appearance of Zeus as his father is expected.

Perhaps most fondly remembered by all is Disney’s film Hercules (1997), in which Zeus (voiced by Rip Torn) is a warm and wise father. “For a true hero isn’t measured by the size of his strength, but by the strength of his heart,” he advises his son.

Hercules in New York (1970) is a cult film best known as Arnold Schwarzenegger’s first (dubbed) role as the titular strongman in contemporary New York. Here, Zeus (Ernest Graves) is responsible for Hercules’ exile – angry, but wanting the best for his son.

Anthony Quinn played Zeus in the TV movie The Circle of Fire (1994), which kick-started the TV series Hercules: The Legendary Journeys (1995–99) and its spin-off Xena: Warrior Princess (1995-2001). Zeus appeared periodically in both. Although Hercules in the series often referred to the neglectfulness of his father, Zeus is still presented as a loving parent in each appearance.

Zeus the comical

Zeus is also perfect to poke fun at. The ancients did it; in Aristophanes’ comedic play The Birds, for example, Zeus’ all-seeing vision is blocked by merely a raised parasol.

Perhaps the best example of this in modern cinema is Russell Crowe’s depiction in the Marvel movie Thor: Love and Thunder (2022). In this campy take, Zeus is all lightning bolts, with a toga that hides very little, and a controversial Greek accent.

But there was also a poignancy in Crowe’s Zeus, such as when he states:

It used to be that being a god, it meant something. People would whisper your name, before sharing their deepest hopes and dreams. They begged you for mercy, without ever knowing if you were actually listening. Now, when they look to the sky, they don’t ask us for lightning, they don’t ask us for rain, they just want to see one of their so-called superheroes. When did we become the joke?

Just as the ancient Greeks had many versions of Zeus, so does the modern world. And Jeff Goldblum’s brilliant performance suggests we certainly haven’t seen the last of Zeus’ thunderbolts onscreen.

A quantum neural network can see optical illusions like humans do. Could it be the future of AI?

Source: The Conversation (Au and NZ) – By Ivan Maksymov, Principal Research Fellow at AI and Cyber Futures Institute, Charles Sturt University

Optical illusions, quantum mechanics and neural networks might seem to be quite unrelated topics at first glance. However, in new research I have used a phenomenon called “quantum tunnelling” to design a neural network that can “see” optical illusions in much the same way humans do.

My neural network did well at simulating human perception of the famous Necker cube and Rubin’s vase illusions – and in fact better than some much larger conventional neural networks used in computer vision.

This work may also shed light on the question of whether artificial intelligence (AI) systems can ever truly achieve something like human cognition.

Ivan Maksymov

Why optical illusions?

Optical illusions trick our brains into seeing things which may or may not be real. We do not fully understand how optical illusions work, but studying them can teach us about how our brains work and how they sometimes fail, in cases such as dementia and on long space flights.

Researchers using AI to emulate and study human vision have found optical illusions pose a problem. While computer vision systems can recognise complex objects such as art paintings, they often cannot understand optical illusions. (The latest models appear to recognise at least some kinds of illusions, but these results require further investigation.)

My research addresses this problem with the use of quantum physics.

How does my neural network work?

When a human brain processes information, it decides which data are helpful and which are not. A neural network imitates the function of the brain using many layers of artificial neurons that enable it to store and classify data as useful or not beneficial.

Neurons are activated by signals from their neighbours. Imagine each neuron has to climb over a brick wall to be switched on, and signals from neighbours bump it higher and higher, until eventually it gets over the top and reaches the activation point on the other side.

In quantum mechanics, tiny objects like electrons can sometimes pass through apparently impenetrable barriers via an effect called “quantum tunnelling”. In my neural network, quantum tunnelling lets neurons sometimes jump straight through the brick wall to the activation point and switch on even when they “shouldn’t”.

Why quantum tunnelling?

The discovery of quantum tunnelling in the early decades of the 20th century allowed scientists to explain natural phenomena such as radioactive decay that seemed impossible according to classical physics.

In the 21st century, scientists face a similar problem. Existing theories fall short of explaining human perception, behaviour and decision-making.

Research has shown that tools from quantum mechanics may help explain human behaviour and decision-making.

While some have suggested that quantum effects play an important role in our brains, even if they don’t we may still find the laws of quantum mechanics useful to model human thinking. For example, quantum computational algorithms are more efficient than classical algorithms for many tasks.

With this in mind, I wanted to find out what happened if I injected quantum effects into the workings of a neural network.

So, how does the quantum tunnelling network perform?

When we see an optical illusion with two possible interpretations (like the ambiguous cube or the vase and faces), researchers believe we temporarily hold both interpretations at the same time, until our brains decide which picture should be seen.

This situation resembles the quantum-mechanical thought experiment of Schrödinger’s cat. This famous scenario describes a cat in a box whose life depends on the decay of a quantum particle. According to quantum mechanics, the particle can be in two different states at the same time until we observe it – and so the cat can likewise simultaneously be alive and dead.

I trained my quantum-tunnelling neural network to recognise the Necker cube and Rubin’s vase illusions. When faced with the illusion as an input, it produced an output of one or the other of the two interpretations.

Over time, which interpretation it chose oscillated back and forth. Traditional neural networks also produce this behaviour, but in addition my network produced some ambiguous results hovering between the two certain outputs – much like our own brains can hold both interpretations together before settling on one.

What now?

In an era of deepfakes and fake news, understanding how our brains process illusions and build models of reality has never been more important.

In other research, I am exploring how quantum effects may also help us understand social behaviour and radicalisation of opinions in social networks.

In the long term, quantum-powered AI may eventually contribute to the development of conscious robots. But for now, my research work continues.

NZ’s Space Agency is both regulator and developer of the aerospace industry – that’s a point of tension

Like the global space industry, which aims to reach a value of US$1.8 trillion by 2035, New Zealand’s aerospace sector is growing rapidly.

But as our latest research shows, it is falling short on addressing urgent sustainability issues because of a perception this would incur short-term costs and slow growth.

Many countries are prioritising the development of national space strategies. Usually, these include plans to increase access to venture capital, grow a specialist workforce and develop flexible regulations and sovereign defence capabilities.

But sustainability leadership in space is crucial, given rising concerns over space debris, and emerging issues such as ozone depletion from rocket launches and the accumulation of alumina and soot particles in Earth’s atmosphere as re-entering objects burn up.

The politics of growth

New Zealand’s aerospace regulatory system was catalysed by Rocket Lab USA’s commercial decision to launch rockets from a spaceport on the Māhia peninsula.

This was followed by the establishment of New Zealand’s Space Agency. This small unit of the Ministry of Business, Innovation and Employment (MBIE) regulates launch payloads and fosters business development by facilitating access to funding for commercial ventures and scientific research.

A central component of New Zealand’s commercial aerospace activity is a bilateral agreement with the US. This enables the launch of American payloads aboard Rocket Lab’s Electron vehicle, negotiated in part by the Space Agency.

MBIE targets an annual revenue of NZ$10 billion by 2030. This is in alignment with New Zealand’s 2023 aerospace strategy and national space policy, and is supported by the appointment of New Zealand’s first cabinet minister for space.

But our study suggests the Space Agency’s dual role as regulator and sector developer introduces a conflict of interest between promoting sustainability and fostering economic growth. This tension is exacerbated by current budget constraints which place too high a demand on the agency’s resources to fulfil both commitments.

The government is simultaneously a customer, investor and regulator of the sector. Yet, it is being relied upon for leadership in sustainability.

Expectations versus reality

Companies are looking to the government for incentives to prioritise sustainability, such as monitoring emissions and pollutants from launches.

The Space Agency has progressed a space debris removal policy, but some say this is not proactive enough. Already, more than 80% of the objects in Earth’s orbits are junk.

The policy does not keep pace with the growing number of market entrants, which will generate a larger environmental footprint on and off Earth.

Minister for Space Judith Collins says her office works with the Ministry for the Environment, the Environmental Protection Authority and industry representatives such as Rocket Lab to “ensure that potential harms to the environment are monitored and mitigated”.

However, this commitment lacks quantifiable details and is not reported in any government documentation. This creates a vacuum where no party (government, industry or the public) assumes responsibility for sustainability.

A sustainability leadership vacuum

The absence of sustainability leadership allows nations with “soft” power, such as the US, to set the rules through the control of resources and norms, such as the renewed goal to head back to the Moon.

To navigate this challenge, we need leadership through international cooperation as well as a robust domestic approach to encouraging and rewarding sustainability initiatives.

Recent initiatives, including small prizes and seed funding for feasibility studies, along with efforts to streamline regulatory approvals, have been announced to aid the growth of the sector.

However, while there is a strong push for accelerated growth, the documents lack clarity on the investment required to sustain business development.

Unlike other countries where government co-financing often plays a crucial role in advancing space-related technologies, New Zealand’s approach to financial support – whether through grants, loans, tax incentives or employment regulations – remains poorly defined.

While the national space policy document cites sustainability values, it falls short of outlining specific approaches or initiatives. Notably, it lacks a clear working definition of sustainability.

The need for clarity and balance

As the aerospace sector grows – amid the uncertainties of climate change, rapid technological developments and continued American influence – we need to clarify the relationship between public and private actors.

Specifically, we need clear guidelines on who is responsible for balancing growth and regulation with environmental and social impacts of industrial activities.

The aerospace sector could benefit from looking to other economically-driven industries that willingly participate in sustainability initiatives, such as the Sustainable Business Network and the B Corp movement.

This approach would address space sustainability concerns in a more balanced manner, as opposed to the growth-driven mindset that often disregards sustainable development.

By shifting the mindset, we can pave the way for a more responsible and forward-thinking aerospace sector.

What are puberty blockers? What are the benefits and risks for transgender children?

Source: The Conversation (Au and NZ) – By Sasha Bailey, PhD Candidate and Research Assistant, The Matilda Centre for Research in Mental Health and Substance, University of Sydney

Puberty blockers are medications that stop the body from producing oestrogen and testosterone. In the clinic, they’re called gonadotropin-releasing hormone agonists (GnRHa).

If adolescents take these medications during puberty, bodily changes associated with puberty are prevented. If these medications are stopped, these bodily changes resume.

Puberty blockers have been used since the early 1980s to treat early-onset puberty in young children.

Beginning in the 1990s, puberty blockers have also been used in transgender adolescents to help prevent the unwanted development of masculinising or feminising physical changes that occur during puberty.

What are the benefits for transgender adolescents?

Many transgender children describe anxiety about unwanted physical changes that will occur because of puberty, especially as adolescence approaches.

For those presumed female at birth, these unwanted changes include breast development and starting periods. For those presumed male at birth, these unwanted changes may include the development of a deeper voice, an Adam’s apple, facial hair and a masculine physique.

Many of these physical changes are irreversible and result not only in gender dysphoria but also misgendering. This is when transgender people are mistakenly assumed to be the gender they were presumed at birth. Misgendering can be a significant and lifelong source of distress.

Some transgender people will seek out surgery to address these unwanted irreversible changes. This might be to masculinise their chest, feminise their face, alter their voice, or reduce their Adam’s apple.

For transgender young people and their families, the most obvious benefits of puberty blockers are to avoid unwanted changes that come with puberty. It can also reduce misgendering and prevent the need for future surgery.

Several studies have assessed the potential benefits of puberty blockers. A 2024 systematic review of the research found consistent evidence showing they effectively suppressed puberty.

The study the review authors identified as being the highest quality found significantly improved psychological outcomes. Puberty blockers reduced suicidal thoughts and actions in transgender adolescents compared to those who had not accessed the treatment.

When should puberty blockers be started?

Puberty blockers can only be started once puberty has commenced. The age at which this occurs varies considerably between individuals. To avoid unwanted physical changes, puberty blockers should ideally begin in early to mid-puberty.

However, many transgender adolescents have been started on puberty blockers in late puberty or even after puberty has finished.

In England, for example, at least 12 months of puberty-blocker treatment was previously mandatory for any transgender adolescent under 18 who wished to access oestrogen or testosterone. This resulted in many young people starting puberty blockers well after their puberty was complete.

One potential problem with commencing puberty blockers beyond early or mid-puberty is that unwanted physical changes have already occurred, so many benefits of this treatment are no longer expected to occur.

The recent systematic review on puberty blockers noted that, while many studies saw improvements in psychological wellbeing, others failed to observe a difference. One possible explanation is that none of these studies accounted for the stage of puberty at which treatment was commenced.

Notably, a more recent study from Harvard University confined the analysis to treatment with puberty blockers in early to mid puberty. It found treatment was associated with significant reductions in anxiety, depression and suicidal thoughts.

Risks of puberty blockers for transgender adolescents

Puberty blockers are generally well-tolerated. But as with any medical intervention, they can also cause unwanted effects. This includes reductions in bone density and fertility, and changes in adult height.

When started beyond early to mid puberty, they are more likely to cause menopausal-like side effects, such as hot flashes. This is due to a reduction in sex hormone production.

There are also potential long-term effects of puberty blockers that are still being investigated.

Brains mature substantially during adolescence. But it remains unclear what effect puberty blockers may have on cognitive development. While the use of puberty blockers in early-onset puberty has not been shown to affect cognitive functioning, studies in transgender adolescents are ongoing.

Where are the randomised controlled trials of puberty blockers?

Randomised controlled trials are typically considered the gold-standard way to study the effectiveness of medical interventions.

To date, there have been no randomised controlled trials of puberty blockers for transgender adolescents, which has led some to label this treatment as experimental. However, conducting such trials of hormonal interventions in transgender youth is problematic, as it would be unethical to withhold treatment for research purposes.

It’s common not to have data from randomised controlled trials in paediatric care more broadly. The use of puberty blockers for early puberty displays similar research gaps.

However, the politicisation of trans young people has seen the use of puberty blockers in transgender adolescents held to a different standard.

How are puberty blockers accessed in different clinical settings?

In the United Kingdom, puberty blockers will now only be accessed by transgender adolescents via the National Health Service (NHS) in a research setting, following the adoption of recommendations by the Cass review, which reviewed gender identity services available to children and young people via the NHS.

One of the main criticisms of the review was it failed to consider the likely harms of denying transgender adolescents hormonal interventions.

In Australia, health experts have also cautioned against comparing our health system to the NHS and highlighted that many of the review’s recommendations align with existing practices within Australian specialist gender services.

Puberty blockers in Australia are accessed by transgender adolescents as part of a comprehensive, team-based approach to gender-affirming care. This emphasises holistic, individualised care which considers the young person’s stage of puberty, while balancing potential benefits and risks.

Would a tech tax be a fair way to make Google and Meta pay for the news they distribute and profit from?

Source: The Conversation (Au and NZ) – By Anya Schiffrin, Senior Lecturer in Discipline of International and Public Affairs, Columbia University

As the News Media Bargaining Code agreements in Australia start to wind down, there is discussion about what will come next. Media academic Andrea Carson calls the codes, passed in 2021, “world-first” legislation because Australia was the first country to use competition law to get Google and Meta to pay news publishers for the news they distribute and profit from.

According to former chair of the Australian Competition and Consumer Commission (ACCC) Rod Sims, about A$250 million flowed to news publishers each year. It’s just a fraction of what would have been a fair price.

Globally, the code has had an enormous impact. Countries that have discussed putting in their own versions have immediately seen Google strike deals with local publishers in an effort to forestall legislation.

The amounts paid out are far less than what is owed. If there were equal bargaining power and Google had to pay for the intellectual property produced by others which it made use of, it would be much more. But something is better than nothing. Thanks to the Australian law, Google has paid out tens of millions of dollars to publishers around the world. We will never know the exact amount, as Google requires publishers to sign non-disclosure agreements.

Google is, of course, dependent on news to make its search more attractive to audiences and advertisers. Research in several countries has also shown just how important quality news is for Google.

Not surprisingly, Google has mounted full-on campaigns against code-type legislation in Brazil, South Africa, California, Indonesia and other countries where it has been proposed.

Meta, which owns Facebook, has been, if anything, even worse. It has been adamant about resisting paying for the news that passes over its platforms. It has threatened to drop all news from countries that adopt and enforce legislation like the bargaining code, spooking regulators.

These tactics have been effective. The two firms have done a good job killing off proposed regulation in many markets.

Now with Meta saying it will pull out of news distribution in Australia, as it did in Canada, and Google reportedly saying it will only sign one-year deals with publishers, the question is: what will come next? Media reports suggest the government is considering a levy on tech companies.

Would a tech levy work?

The OECD has tried and failed to get a global agreement to raise corporate taxes – an agreement that would have prohibited digital taxes. In the meantime, the US government, influenced by its tech giants, is strongly opposed to such taxes. US Treasury Secretary Janet Yellen has spent a good deal of time calling up her counterparts and telling them not to impose them.

However, since the US has essentially blocked a global agreement on corporate taxes, many countries have decided to keep or adopt digital services taxes. Indeed, more than 18 countries have such taxes and some 20 others have proposed them. According to PWC, these may be levied on online sales, digital advertising, data usage, e-commerce, or streaming services.

While levies on streaming services to fund local content have been put in place in France, Switzerland, Canada, Portugal and are coming into force in Spain, and they’re being discussed in Australia, no government has used the funds raised from digital service taxes to directly support journalism.

In theory, taxes on tech have advantages over bargaining codes. The Australian version of the bargaining code doesn’t fully resolve the problem of power imbalances between the large social media firms and the publishers, and there were no requirements to spend the money on journalism. In theory, a tax on tech could address these shortcomings.

However, before publishers start pushing for taxes on tech to support journalism, there are a few things to consider. Is there public support for giving the revenue raised to journalism rather than putting it into the general kitty to be spent by the government? If there is support for a tax to support journalism, who decides on the allocation? How could there be safeguards to ensure governments don’t use the funds to support their media allies?

It’s also important to remember that, of course, tech firms oppose taxes. They’ve offshored their revenues for years and resisted paying taxes. In the US, Maryland in 2021 passed a tax on digital advertising and the state has spent years fighting off multiple lawsuits. We should expect even more resistance to a tax than to the bargaining code.

Making tech firms pay for what they use to make money

The bargaining code addressed a simple issue: how to force the platforms to pay fairly for the intellectual property they were effectively stealing and which enhanced their profits, given the imbalance of powers in this market. In doing so, it helped address another major societal issue: how do we pay for quality journalism, a public good from which all benefit? It never pretended to adequately resolve that question, but at least it was a start.

Every country needs to address the theft of intellectual property that diminishes both the incentives and ability to produce the news on which we all — including the platforms — depend. The bargaining codes were a start.

But democratic governments should also publicly fund quality news media. With the platforms having appropriated for themselves so much of the advertising revenues on which the media used to depend, it is natural to turn to digital taxation. It is not a matter of either/or; it should be a matter of both/and. Pragmatism should prevail. As the economist Dean Baker says, “the best policy is the policy you can pass”.

What if Big Oil championed – and profited from – the green transition? Here’s how it could work

Like the petroleum industry itself, households are heavily invested in existing transport technologies. Getting oil and gas companies – and consumers – to switch to zero-emissions transport is a huge challenge.

We can’t presume battery electric vehicles (EVs) will displace fossil fuel vehicles any time soon. They are not accessible to most households and don’t offer radically better transport services. They drive on the same congested roads with the same speed limits.

On the supply side, electrifying entire transport fleets requires major infrastructure expansions. Even with strong demand, such infrastructures will struggle to displace Big Oil’s dominant and affordable alternative.

It’s a classic chicken-and-egg predicament. Consumers and vehicle makers won’t switch unless they are confident the required refuelling infrastructures will be available. But those infrastructures won’t materialise without sufficient demand.

Repurposing existing infrastructure to supply clean fuels could convince both consumers and vehicle manufacturers to make the switch. But what would that take?

Clean fuel alternatives

Major economies (including the United States, European Union and Japan) and car manufacturers, such as Toyota and BMW, are actively promoting clean hydrogen-based technologies such as hydrogen fuel cell vehicles. Toyota and some heavy vehicle manufacturers are also investing in vehicles that could combust clean hydrogen.

Whether “green hydrogen” might work for mass transport remains hotly debated. But it’s not the only possibility – biofuels made from renewable feedstocks have the potential to at least partly decarbonise transport (especially aviation).

And so‑called “drop-in fuels” could also substitute for fossil fuels. Known as e‑fuels, these are synthetic fuels made by combining hydrogen with carbon dioxide.

As such they could decarbonise transport faster and more widely because they can be used in existing vehicles – and supplied via existing infrastructures. A recent EU ban on new fossil fuel vehicle sales from 2035 was softened to allow for this.

As with EVs, vehicles running on clean hydrogen, biofuels or e‑fuels don’t revolutionise transport beyond reducing emissions. But they might get a head start on EVs by solving that chicken-and-egg problem: making possible the conversion of entire vehicle fleets to run on clean fuels, while developing the required refuelling infrastructures.

Affordability and scale

Repurposing existing fossil fuel infrastructures to supply clean fuels could be faster and cheaper than building new ones, such as the massively expanded electricity systems required for mass EV adoption.

For example, zero-emissions hydrogen can be produced from natural gas, but the process itself produces greenhouse gas emissions. Carbon capture storage (CCS) – removing the emissions and storing them securely in geological structures such as depleted gas fields – is one possible solution.

The Intergovernmental Panel on Climate Change sees CCS as feasible and playing a significant role in reducing greenhouse emissions. This would mean oil companies could adapt to producing zero-emissions hydrogen while renewable hydrogen or e‑fuel production develops.

The required geological structures are located near oil and gas infrastructures, which could also be converted to transport the resulting clean fuels.

These technologies might not yet be economically viable. But the same was true of EVs only 20 years ago. Concerted investment – and production at scale – was pivotal in improving their economics.

Repurposing fossil fuel infrastructures also opens the door to converting existing vehicles to run on clean fuels. This requires little or no modification for drop-in fuels, which are substitutable for existing fuels by design. Alternatively, vehicles can be converted to combust clean hydrogen (or dual fuel mixtures).

This could be much more affordable – and attractive to vehicle owners – than buying new vehicles (even assuming suitable options were available).

Putting coal out of business

In the process, Big Oil could avoid its existing assets becoming sunset investments. Critically, it could also profit from repurposing its infrastructures, by decarbonising sectors currently dominated by the other major carbon polluter, coal.

For example, hydrogen is a more credible substitute than electrification in some large coal-consuming industries, such as steelmaking.

However, given the need for scale and co‑ordination, it’s unlikely individual oil and gas companies could profitably repurpose their infrastructures on their own.

But industry-wide agreement and co‑ordination to produce a particular clean energy (or mix of energies) could substantially reduce investment risks. Laws against collusion would likely prohibit such agreements, so targeted exemptions and close regulatory oversight would be needed.

Relatedly, firms might commit to accelerating the green transition in return for regulated – but guaranteed – rates of return. While not perfect, this strategy has a precedent in the way competing US electricity utilities became regulated monopolies.

Alternatively, franchise bidding could see firms pay to win a time-limited monopoly to achieve an accelerated green transition.

This has been used to support the rollout of other natural monopoly infrastructures such as water networks, toll roads, cable TV and fibre broadband. It creates a contest that Big Oil couldn’t afford to lose.

Repurposing the past

History offers relevant lessons. EVs were once a dominant automobile technology over a century ago. But they were quickly displaced with the arrival of affordable and convenient fossil fuel vehicles.

Emerging clean fuels hold the promise of fast refuelling and long ranges, combined with zero emissions, meaning the days of EVs could again be numbered.

Recall, too, that 19th-century investors accelerated the transition to rail by buying canals that competed with trains. They then either retired them or repurposed them as rail routes.

Had those investors anticipated motorised vehicles and roads displacing rail, they likely would have invested less. That they didn’t means current generations benefit from access to more railways than would otherwise be available.

The same is potentially true for the fossil fuel industry. Past investment in polluting infrastructures could benefit current and future generations if repurposing those infrastructures accelerates the green transition.

What are ‘click frauds’ – and how can we stop them?

In the world of the internet, clicks are currency. The more people click on a website, social media post or an advertisement, the more that content generates revenue.

But cybercriminals can exploit this rapidly growing market for clicks through what are known as “click frauds”. And everyone, from everyday internet users to large organisations that use the web to share content or sell their products, is vulnerable.

But what exactly are “click frauds”? And what can be done to prevent them?

What is click fraud?

Click fraud occurs when someone creates a network of bots or sets up “farms” of human workers to generate clicks online. It can take many forms.

Fraudsters often use automated bots or click farms to generate fraudulent clicks on ads or likes on their own websites. They create websites and invite businesses to advertise on their site at a cost. If advertisers are paying per click, then the fraudster will earn money for their business (which is often a fake business) and divert traffic to their site.

Alternatively, a genuine business might create their own advertisements and place them on various websites. Cybercriminals might bombard these advertisements with clicks, which will be very costly for genuine businesses when they are paying per click.

The motivation here may be that the criminal has their own genuine business, and they are hoping the advertising cost will be so expensive it will put their competitor out of business.

A third method is that a criminal may create a fake website they hope users will click on.

This is because the site has a malicious link that will download malware onto a user’s computer, or because they hope to scam the user in another way (for example, by paying upfront fees for a service or items that do not exist).

By increasing traffic to their website, the website moves up in online search rankings. This impacts the general user who believes that because the site is high up in the order, it is a genuine and popular business they should trust.

Higher clicks can lead to higher trust

The psychological theory of planned behaviour provides some explanation for why people might trust a site that has numerous clicks and likes compared to a site that has few.

According to the theory, human behaviour is guided by three main factors: attitudes, subjective norms and perceived behavioural control.

Let’s consider each of these with respect to click fraud:

Attitudes: people often associate higher numbers of clicks, likes and traffic with credibility and trustworthiness. This is based on the belief that if many others engage with a site, it must be valuable, reputable or of high quality.

Subjective norms: subjective norms involve the perceived social pressure to perform or not perform a behaviour. If people see their peers, or society in general, trusting and using sites with many clicks and likes, they may feel pressured to trust these sites as well. This social influence can reinforce the behaviour of valuing and trusting high-traffic sites.

Perceived behavioural control: high traffic, clicks and likes can serve as indicators a site is reliable, reducing the perceived risk and effort required to evaluate it. When people perceive it is easier to trust a site with many popularity indicators, they are more likely to trust that site.

How can you prevent click fraud?

Ad fraud software is one method to prevent harm from click fraud.

Businesses can use specialised ad fraud detection and prevention tools, such as ClickCease, Fraudlogix or DoubleVerify. These tools can analyse click patterns, detect anomalies and block suspicious activity.

Businesses can also use IP blacklists to identify and block known fraudulent IP addresses. An IP – or “internet protocol” – address is a unique identifying number for any device connected to the internet.

Businesses can also employ geo-targeting to limit ad exposure to specific regions or locations, reducing the risk of fraudulent clicks from irrelevant or high-risk areas.

The general internet user can also be a part of the solution. We need to change our online shopping and trust behaviours. Some of the following checks will help users determine if a website or business is genuine:

  • verify the source. Is it credible and well-known?
  • hover over the URL. Is it a known web address? It may mimic one, so a close inspection is needed. For example, the legitimate website www.google.com might be www.go0gle.com
  • become more aware of click fraud. Knowing it is prolific and that you are most likely to encounter it in your everyday life will help you learn to spot it and avoid it.
  • use antivirus and anti-malware software protection to help protect you, identify malicious websites, and keep your software up to date. You cannot solely rely on this software to protect you, but it is an important part of the solution.

Married to the job? How having a self-employed partner might be hurting your happiness

Ever considered working for yourself? Some of the oft-touted perks make it seem like a dream. You get more control over your time, total freedom over creative and business decisions, and a better work-life balance.

For many self-employed entrepreneurs, however, this promise proves a cruel mirage. Financial insecurity, unforeseen obstacles and having to work lonely late nights can all make the reality very different.

And although they might be running a business solo, entrepreneurs don’t get to exist in their own little bubbles. The pressures they face can put serious strain on all of their relationships.

Perhaps none so much as that with a spouse, who gets a front-row seat to all the ups and downs.

My recent research sought to examine what it’s like when a partner’s business becomes the other significant other.

What it found was troubling, but perhaps unsurprising – that having a self-employed partner can significantly reduce your life satisfaction, especially when family, leisure and work are your own key priorities.

An important contribution

The self-employed form a small but significant chunk of Australia’s total workforce – just under 16% in 2022. They also make an important economic contribution.

It’s important to note that self-employment isn’t always a choice. In challenging economic periods, the percentage of self-employed will often rise as people are “pushed” into starting their own businesses out of necessity.

This phenomenon, also known as the “unemployment push” or “refugee effect”, suggests that people often turn to entrepreneurship when faced with limited job opportunities or a poor job market.

This kind of necessity-driven entrepreneurship can provide a crucial source of income for entrepreneurs. It can also generate new job opportunities for others, if these new businesses become successful enough to start hiring.

But it’s not easy, and can pose significant challenges for their spouses and other close family members. These should not be overlooked.

Partners bear the costs, too

My study examined data spanning more than 80,000 respondents and 60 countries from the latest World Values Survey, which is conducted every five years.

It found the spouses of self-employed individuals tend to have lower life satisfaction.

A range of factors could be contributing to this effect, from the heavy stress of financial uncertainty to difficulties disconnecting from work, which can strain personal relationships.

My research also found the perceived importance of family, leisure and work amplified this effect. The more important these aspects were to a spouse, the lower their life satisfaction was likely to be.

This is largely in line with what you’d expect. The demands and irregular hours associated with self-employment can lead to less family time, less time for shared leisure activities, and increased stress.

On top of this, ambitious, career-focused individuals might struggle to manage the additional responsibilities and stress that come with their partner’s self-employment, leading to lower life satisfaction.

The picture was even worse when both partners were self-employed – life satisfaction was significantly lower. This reflects some unique challenges that are different again to those of the other households.

Having just one self-employed partner can significantly disrupt the work-family balance. Now imagine both! It can quickly become extremely challenging to manage responsibilities like caring for children, let alone find time off to be together.

In Australia, where work-life balance is a deeply valued cultural norm, the strain of having a self-employed spouse can be particularly challenging.

What should be done?

The self-employed and their partners make a valuable contribution to Australia, so it’s important we look after them.

Our findings suggest we need to create better support systems for families where one or both partners are self-employed, particularly in economic downturns.

This could include mental health supports to deal with the stress of self-employment and financial planning services to assist in managing the ups and downs.

Policies designed to directly address the financial insecurity of self-employment could have a disproportionate impact. This could include new tax breaks specific to solo entrepreneurs.

Expanding access to affordable childcare could also make it easier for both partners to juggle their work and home responsibilities, especially when money is tight.

The benefits of working for yourself shouldn’t cost the wellbeing of those closest to you. By creating better support systems for self-employed families, we can slowly fix this equation.

Happy Father’s Day, Daddy Pig – despite your faults, you’re TV’s greatest dad

Source: The Conversation (Au and NZ) – By Ben McCann, Associate Professor of French Studies, University of Adelaide

Peppa Pig/YouTube

The children’s show Peppa Pig, first screened in the United Kingdom in 2004, is now broadcast in more than 170 countries and has become a billion-dollar brand. Its smart three-act structure, told in five-minute episodes, has been used to teach creative writing and even to help us think philosophically.

Having watched Peppa Pig for 12 years with my own kids, I’m always drawn back to Daddy Pig – the cheerful, striving figure who is often considered “silly” by his children.

Daddy Pig is constantly being fat-shamed and ridiculed, yet he remains steadfast and hardworking. He is jovial, explains science to his family, (eventually) listens to his wife and children and, most importantly, never loses his patience.

This Father’s Day, I’d like to take this opportunity to recognise Daddy Pig for being a role model for dads all over the world.

A hapless dad?

Daddy is a classic example of the “hapless dad” trope commonly found in family-oriented films and TV shows. These father figures are typically portrayed as well-meaning, but clueless and inept when it comes to handling chores and responsibilities.

Hapless dads struggle to cook, clean or care for children, and rely on others (usually the mother) to bail them out. They have good intentions, but they’re bad at following through – and their efforts often backfire.

In the episode Pancakes, Daddy’s flipped pancake sticks to the ceiling. In Daddy Loses His Glasses, he realises he has been sitting on his glasses for the whole episode. Each episode invariably ends with everyone laughing at “silly Daddy”, including Daddy himself.

In my favourite episode, Daddy Puts Up A Picture, Daddy hammers a nail into a wall, with predictably unfortunate results. But he keeps calm. He asks Peppa and George to help him as he plasters and paints to repair the damage. He then bathes them and everything returns to normal.

It’s a great example of how to create tension in storytelling: will Daddy clean everything up before Mummy Pig gets home? It also teaches a valuable life lesson: don’t panic.

Daddy Pig isn’t hapless. He is a wonderful role model who always gives 100% to his work, exuding a warmth and stoicism that ennobles us.

Comic relief

Comic relief characters in children’s TV and literature personify cheerfulness and jokiness. Comedy seeks to minimise the anxieties felt by the reader or audience, by reinforcing the message that life is not to be taken too seriously.

As children’s literature expert Kerry Mallan noted in 1993, these characters have faults:

they may, for instance, be vain, lazy, frivolous, clumsy or naive but these faults are not fatal […] and the reader or audience is able to laugh at the comic character’s expense.

Daddy Pig declares himself “a bit of an expert” in several things, including map reading, kite flying and trumpet playing, but is usually proven clueless. He says he can speak French, but he can’t.

These bungling, clumsy attempts to exert his patriarchal authority gently poke fun at traditional gender stereotypes and portray Daddy as someone who is at ease with his own frailties.

Children will chuckle at slapstick situations such as Daddy getting stuck in cement, while adults will appreciate the more subtle humour such as how Daddy fixes the computer by turning it off and on again, or when he sends his family to sleep while reading them a book on concrete. This double play of humour links Daddy Pig back to the Shakespearean fool.

Yet, every once in a while, Daddy also gets to “win” an episode. In Long Train Journey, Daddy is invited to go overseas for work. He is treated like royalty, served coffee and orange juice in the buffet car (not even the king is afforded such luxury) and is finally recognised for his fame and expertise in all matters of concrete.

Importance of play

Researchers have noticed the importance of father–child play. Like Bandit from Bluey, Daddy’s play is often physical, spontaneous and playful.

In Daddy’s Birthday, he is the happiest when jumping in muddy puddles with Peppa and George. In Marble Run, he turns the whole house into a marble run course – and the children are delighted.

In Camping, Daddy shows Peppa and George how to light a campfire by rubbing two sticks together. He could just use the matches Mummy Pig offers, but he perseveres and eventually the fire is lit – and everyone cheers.

Daddy’s playful nature helps create a positive and enjoyable environment for his family. He is actively involved in their lives and is always there to give love and support during important moments.

Daddy Pig, we salute you

After nearly 400 episodes, Daddy Pig continues to embody the lovable yet imperfect patriarch, whose actions demonstrate the importance of family values, hard work and knowing when to quit. Richard Ridings, the British actor who has voiced the character since 2004, has often reiterated Daddy Pig’s resilience.

In Father’s Day, Peppa and George make Daddy a cake full of cereal, ketchup and blue cheese. Daddy’s response? “Tasty!”

Despite all the slings and arrows thrown his way, Daddy Pig embraces life, shakes off its frustrations and keeps his spirits up. What more could you ask for?
