What do a billionaire, a former vice president, and a US democratic socialist have to do with Australia’s nearly three-decade run of economic growth?

More than you might think.

The race for the Democratic Party’s 2020 Presidential nomination is far from over – in fact voting in the first state (Iowa) doesn’t even begin until January. But Senator Elizabeth Warren has become the front-runner in betting markets and national polls, pulling ahead of former vice president Joe Biden.

Warren is running on a “democratic socialist” platform of banning private health insurance, imposing a wealth tax and more rigorously examining proposed trade agreements. Biden is much more centrist – he was Barack Obama’s vice president after all – but he is struggling to maintain the lead he once held.

This has a number of people freaked out. Among them is former New York mayor (and former Republican) Mike Bloomberg, who has filed paperwork to get himself into the Democratic primary race.

Bloomberg is a pro-market, socially liberal, three-term mayor of New York. He amassed a US$50 billion fortune by creating the category-killing Bloomberg terminal for financial data and securities trading.

He has taken progressive stands on gun control, gay rights and women’s reproductive rights.

And on climate change he spent half a billion dollars on climate mitigation projects as well as campaigning with the environment group Sierra Club (successfully) for coal mines to be closed.

Bloomberg’s path to the Democratic nomination is far from assured, but in Australia someone like him would be in the mould of prime ministers past.

And that tells us something important about our internationally unusual long run of economic growth.

Straight down the middle

Since Bill Hayden became Labor (and opposition) leader in 1977 and put to rest the economic upheaval of the Whitlam era, Australia’s two major political parties have maintained, for the most part, staunchly centrist economic policies. They’ve combined the virtues of markets with a strong social safety set.

The Hawke-Keating government famously opened up the Australian economy to the world: floating the Australian dollar, deregulating the banking system, slashing tariffs, and privatising sleepy state-owned enterprises.

John Howard not only continued this legacy but introduced the Goods and Services Tax – a much more efficient form of taxation than had existed – and successfully negotiated the Australia-US Free Trade Agreement.

And though the Rudd-Gillard-Rudd government may have lacked stability, it did not lack major economic achievements.

Rudd and then Treasury boss Ken Henry acted decisively with stimulus and bank guarantees to avoid the economic disaster that hit most of the rest of the world.

Gillard introduced a carbon tax that had an almost immediate effect in reducing Australia’s emissions.

While the Abbott-Turnbull-Morrison government’s stance on climate change has been rightly criticised (often by yours truly), it has continued to enact free trade agreements, the most recent of which, the Regional Comprehensive Economic Partnership, might be truly transformational.

Sometimes veering to the sides

Although that centrism has served Australia well socially and economically, there have been moments where policy looked like it would veer away from the centre.

Labor opposed the goods and services tax. The current government has flirted with government guarantees for new coal-fired power plants, which was a policy more in the spirit of Marx and Lenin than Howard and Costello.

Holding the centre

The current depressing state of the Australian economy (pun intended) might provide the biggest test yet to centrist economic policy.

Wage growth is sluggish (Wednesday’s figures showed annual growth slipping from a historically low 2.3% to 2.2%) and unemployment is climbing (Thursday’s figures showed the unemployment rate climbing from 5.2% to 5.3%).

There’s pressure from both the left and the right to “do something”.

Cutting immigration, moving away from free trade, propping up failing industries, or offering selective wage rises to particular sectors (such as childcare workers) are among the “somethings” that have been on the table or partially implemented.

Read more: If you think less immigration will solve Australia’s problems, you’re wrong; but neither will more

The Hawke-Keating and Howard-Costello governments sustained centrist economic policy for more than two decades.

They did it not only through a series of sound policy choices, but also through a narrative about the virtues of markets coupled with a social safety net.

It’s a narrative under threat. In Australia it hasn’t been drowned out yet.

Eyebrows can turn a smile into a leer, a grumpy pout into a come hither beckoning, and sad, downturned lips into a comedic grimace.

So, it’s little wonder these communicative markers of facial punctuation have been such a feature of beauty and fashion since the earliest days of recorded civilisation.

From completely shaved mounds to thick, furry lines, eyebrows are a part of the face we continue to experiment with. We seek to hide, exacerbate and embellish them. And today, every shopping strip and mall has professionals ready to assist us with wax, thread and ink.

Minimising distraction

In the court of Elizabeth I, to draw attention to the perceived focal point of a woman’s body – her breasts – the monarch would pluck her eyebrows into thin lines or remove them completely, as well as shaving off hair at the top of her forehead.

This was an attempt to make her face plain and blank, thereby directing the viewer’s gaze lower to her substantial décolletage.

Although the intentions were different, nonexistent or needle-thin brows had also been common in ancient China and other Asian cultures, where women plucked their eyebrows to resemble specific shapes with designated names such as “distant mountain” (likely referring to a central and distinctive point in the brow), “drooping pearl” and “willow branch”.

In ancient China, as well as in India and the Middle East, the technique of threading – the removal of hairs by twisting strands of cotton thread – was popular for its accuracy. The technique, referred to as “khite” in Arabic and “fatlah” in Egyptian, is enjoying renewed popularity today.

In Japan between 794 and 1185, both men and women plucked their eyebrows out almost entirely and replaced them with new pencilled lines higher up on the forehead.

Eyebrows of Ancient Greece and Rome, on the other hand, are frozen in contemplation.

They are often represented in sculptures through expressive mounds devoid of individual or even vaguely suggested hairs: in men they are strong and masterful furrows above a purposeful gaze; in women, soft and emotive.

This lack of detail demonstrates a fondness, in some corners of ancient Greek and Roman society, for joined or “continuous” brows.

Poet of tenderness, Theocritus, openly admired eyebrows “joined over the nose” like his own, as did Byzantine Isaac Porphyrogenitus.

Brows as barometers

For much of the 19th century, cosmetics for women were viewed with suspicion, principally as the province of actresses and prostitutes. This meant facial enhancement was subtle and eyebrows, though gently shaped, were kept relatively natural.

Despite this restraint, a certain amount of effort still went into cultivation. A newspaper article from 1871 suggested intervention during childhood to thicken them:

If a child’s eyebrows threaten to be thin, brush them softly every night with a little coconut oil, and they will gradually become strong and full; and, in order to give them a curve, press them gently between the thumb and forefinger after every ablution of the face or hands.

As fashions became freer after the first world war, attention was once again focused more overtly on the eyes and eyebrows.

This was partly to do with the development of beauty salons during the 1920s, many of which offered classes in makeup application so women could create new, bold looks at home.

The fashion for very thin eyebrows was popularised by silent film stars such as Buster Keaton and Louise Brooks, for whom thick kohl was a professional necessity and allowed a clearer vision of the eyebrows – so crucial, after all, for nonverbal expression on screen.

The amount of attention paid to eyebrows continued to change according to specific global events.

In the 1940s, women began to favour thicker, natural brows after several decades of rigorous plucking to achieve pencil-thin lines. Considering the outbreak of the second world war had forced many out of a wholly domestic existence and into the workforce, it stands to reason they had less time to spend in front of the mirror, wielding a pair of tweezers and eyebrow pencil.

The post-war 1950s saw wide, yet more firmly defined brows and from the 1960s onwards various shapes, sizes and thicknesses were experimented with, accompanied by a firm emphasis on individuality and personal preference.

More than mono

When Dwight Edwards Marvin’s collection of adages and maxims, Curiosities in Proverbs, was published in 1916 it included the old English advice:

If your eyebrows meet across your nose, you’ll never live to wear your wedding clothes.

The “mono-” or “uni-brow” had become suggestive of a lack of self care, particularly in women.

Research undertaken in 2004 reported American women felt judged and evaluated as “dirty”, “gross” or even “repulsive” if they did not shave their underarm or leg hair, or pluck and shape their eyebrows. As the most visible of these areas, untamed eyebrows perhaps point to the bravest exhibition of natural hair.

Today, model Sophia Hadjipanteli sports a pair of impressively large, dark joined eyebrows, and has assertively fought back against the legion of online trolls who have abused her for this point of difference.

A reference back to the distinctive brows of Frida Kahlo, Hadjipanteli’s look is linked to an ongoing debate surrounding women’s body hair.

Giving a pluck

For many, excessive plucking and shaping has become emblematic of the myriad requirements women are expected to comply with to satisfy restrictive societal beauty norms.

Still, plenty of people with eyebrows are dedicating time and money to their upkeep. In Australia, the personal waxing and nail salon industry has grown steadily over five years to be worth an estimated A$1.3 billion and employ more than 20,000 people.

Over this time, social media has offered a diverse and changing menu of brow choices and displays.

One choice: the “eyebrow slit” – thin vertical cuts in eyebrow hair – has re-emerged online and in suburban high schools. It’s important to emphasise re-emerged because, with beauty as with clothing, what goes around comes around.

The eyebrow slit was especially popular amongst hip hop artists in the 1990s, and draws appeal due to its flexibility: there are no firm rules as to the number or width of the slits, which originally were meant to suggest scarring from a recent fight or gangsta adventure. More recent converts have been accused of cultural appropriation.

Some have experimented by replacing plain slits with other shapes, such as hearts or stars, though plucking or shaving brows into unusual shapes is – as we have seen – by no means new either.

Facing the day

If the popularity of recent trends is anything to go by, eyebrow fashion will remain on the lush side for some time.

The “Scouse” brow (very thick, wide and angular eyebrows emphasised with highly defined dark pencil shapes: named after natives of Liverpool in the United Kingdom) is still trending.

The “Instagram eyebrow” (thick brows plucked and painted to create a gradient, going from light to very dark as the brow ends) is inescapable on the platform and beyond. Makeup for brows is therefore also likely to continue, providing a clear linear connection through nearly all the eyebrow ideals since ancient times.

The latest offering to those seeking a groomed look is “eyebrow lamination”, a chemical treatment that uses keratin to straighten individual hairs – a kind of anti-perm for your brow.

Those still searching for their eyebrow aesthetic may benefit from some wisdom shared by crime and society reporter Viola Rodgers in an 1898 edition of the San Francisco Call newspaper.

In a piece which ran alongside an interview with the man who had inspired Mark Twain’s Tom Sawyer character, she advised that the appearance of one’s brow conveyed more than just their grooming habits:

An arched eyebrow … is expressive of great sensibility … Heavy, thick eyebrows indicate a strong constitution and great physical endurance … Long, drooping eyebrows indicate an amiable disposition and faintly defined eyebrows placed high above the nose are signs of indolence and weakness.

Eyebrow slits? We can only imagine what Viola would think.

When five former fire chiefs held a news conference on Thursday to urge the federal government to take more action on climate change, it was a challenging moment for Scott Morrison.

Those who fronted the cameras represented a group of 21 men and two women, who make up the Emergency Leaders for Climate Action. These people have led fire and emergency services all around the nation.

They’re powerful voices, because they are advocates with compelling experience and expertise. The group’s messages are that we’re in “a new age of unprecedented bushfire danger”, climate change is the key reason why things are getting worse, and the government needs to respond with more resources and a better policy to reduce emissions and move to clean energy.

The problem is, as group founder Greg Mullins, former Fire and Rescue NSW commissioner, put it succinctly, “this government fundamentally doesn’t like talking about climate change”.

The devastating fires are a dramatic additional element intensifying the pressure on a government already increasingly on the back foot over climate change, as it responds poorly to a complex set of policy problems.

It’s not that Morrison denies climate change. It’s that he refuses to acknowledge it as a central issue, either because he doesn’t see it as such or because he fears provoking his right wingers.

Consider three factors now weighing on Morrison.

First, in Australia (as internationally) activism is rising. This should be broadly defined. Put aside the Extinction Rebellion, which may alienate more people than it persuades. Rather, include in the definition the many companies now factoring climate change into their planning, investment, and public statements.

Morrison might rail against activists hitting resource companies via secondary boycotts, and commentators might denounce so-called “woke” behaviour by business. But the long view indicates a tide is running here and its direction is clear.

Second, there is a general recognition the government’s climate policy is badly wanting. Emissions are rising. Its modest centrepiece – a fund paying for projects to reduce or capture emissions – isn’t doing the job. The fund’s limitations were tacitly acknowledged when recently the government set up a panel which sought submissions on how it could be enhanced.

More broadly, the government’s lack of a coherent energy policy means continued uncertainty for investors.

Third, Angus Taylor, minister for energy and emissions reduction, has frustrated those in the energy sector and the states. He’s too confrontational and short on people skills (in contrast to his predecessor Josh Frydenberg). His cheap shot accusing the Sydney City Council of ludicrous travel costs blew into a major embarrassment.

Next Friday Taylor will again be under scrutiny when he meets the states at the COAG energy council. The last meeting, nearly a year ago, turned into a nasty stoush between Taylor and the NSW minister.

If Taylor’s performance doesn’t improve in the next few months Morrison – who will be the one eventually carrying the can for policy failure – surely should move him. It would be interesting to see how (say) a Simon Birmingham or a Mathias Cormann would go in the portfolio. Better, you’d think.

It was no wonder Morrison wanted to contain partisan argument while the fires rage. It’s a reasonable view for a prime minister to take, with a basis in past practice, but was also politically driven.

Morrison has been assisted in this by Labor, despite the ALP recently voting in parliament (without success) for a “climate emergency” to be declared. Anthony Albanese believed there was no gain in seeking to score points during a disaster, and danger in doing so.

But a moratorium, although mostly adhered to by Liberal and ALP federal politicians, was never going to happen more generally. Indeed some people, like the retired fire chiefs, judged this was precisely the moment to press their point.

It was predictable the Greens would strike hard; climate is core ground for them. But that Deputy Prime Minister Michael McCormack would take the bait, leaping in to condemn “the ravings of some pure enlightened and woke capital city greenies”, showed a lack of discipline, probably in part a reflection of the strain the Nationals leader is under as he tries to manage a difficult party room.

Some believed McCormack was playing to his base. If so, he’d only be talking to part of it, most notably those with an eye to the coal industry. Many farmers are very aware, first hand, of the impact of the changing climate.

After its election loss, there’s been much talk about how Labor is caught between its dual constituencies on climate – inner city progressives versus traditional suburban workers.

But the Liberals face their own dilemma, which could deepen as the issue amps up in the electorate. We have seen over many years the split within the Liberal party, and the very high costs it has extracted. As Morrison assesses how to pitch to voters in the future, he might have to be careful of straining internal unity.

Read more: Firestorms and flaming tornadoes: how bushfires create their own ferocious weather systems

Over coming months, the fires’ impact on public opinion will presumably be measured in the focus groups through which the government hears its “quiet Australians”.

More immediately, Morrison won’t be able to escape a response when this crisis passes. His moratorium will make expectations greater.

John Connor was formerly CEO of the now defunct Climate Institute, which commissioned from the CSIRO a 2007 research paper – that turned out to be prescient – on the link between climate and bushfires, titled Bushfire Weather in Southeast Australia: Recent Trends and Projected Climate Change Impacts.

Connor, who now heads the Carbon Market Institute (which describes itself as a peak industry body for climate action and business) suggests the current situation provides the opportunity for an “armistice” – a chance to build a platform on the middle ground for the climate debate.

One step, Connor says, would be for the government to establish a parliamentary inquiry to examine the growing risk climate change presents for the fire scene and the resources required for the future.

“It could be a stepping stone to a more mature debate about carbon policy for the broader economy,” Connor says, although he admits “I’m a professional optimist”.

The government’s former drought co-ordinator, Stephen Day, wrote in his report, finally released last week: “As a consequence of climate change drought is likely to be more regular, longer in duration, and broader in area”.

What’s striking about Day’s observation is how matter-of-fact it is. Climate change is stated as a reality from which other considerations flow. The same reality applies to bushfires. It also applies to the need to move the economy to a new energy mix and net zero emissions by 2050.

Australia continues to experience unprecedented destruction from bushfires. Now is the time to harness our technological tools, and find innovative ways to help alleviate the problem, and also prevent future disaster.

Predictive mapping has been a vital tool in an ongoing effort to identify at-risk forest areas and proactively manage the risks of fires. It works by analysing images to see what human eyes don’t always see.

Now, progress in technologies such as artificial intelligence (AI), drones, and Internet of Things sensors have opened new ways for us to better prevent and effectively respond to bushfires. For this, the key is to have plenty of data relevant to that location.

Using tech to gather and distribute data

Crucial data needed for bushfire prevention planning can come from a range of sources, including Internet of Things (IoT) sensors collecting weather data, archived data from the past, modelling tools, satellite images, and even social media.

These technologies can converge to gather a diverse range of data, helping us make predictions about the likelihood of an event occurring in a specific location with more speed and accuracy than ever before. Such predictions provide timely and targeted information that can greatly aid emergency services in doing their job, especially as they often have stretched resources on the ground.

Read more: How does poor air quality from bushfire smoke affect our health?

Our goal now should be to integrate our use of these emerging technologies into existing systems of State Emergency Service departments, which can relay more strategically targeted information to local authorities who need it. This can be built into their existing systems.

The potential of mesh networks

Next-generation “mesh networks” are an emerging technology made possible by the convergence of 5G, artificial intelligence, billions of Internet of Things (IoT) sensors, and virtual and augmented reality.

Whereas older networks are based on a limited number of access points, with mesh networks every person with a 5G-enabled smart phone is a node capable of connecting with everyone else. When 5G mobile phone service is rolled out across Australia, we’ll be able to do this.

With this technology, people in a bushfire or other disaster-afflicted area can create a local mesh network using their smartphone. They could contribute by recording 360 degree videos, make narrative reports about unfolding events, take close-up photos etc, then distribute these to the mesh network.

Photogrammetric artificial intelligence can produce reliable information about physical environments by processing captured imagery. It integrates these videos to create live holograms in real time. This form of virtual reality will put observers right there on the ground. This will help authorities away from the scene to verify reports and more effectively coordinate relief efforts.

It may also assure family and friends that their loved ones in afflicted areas are OK.

Learning from others

California’s One Concern is an example of a next-generation disaster management service that provides a model for what could be achieved in Australia.

It has partnered with various city governments, including San Francisco and Los Angeles, to create virtual models of particular regions’ physical environment, by assigning “digital fingerprints” to each significant feature of that environment. The service constantly monitors any thermal shifts and seismic movement across the sensor network.

Processing this data together with historical data allows One Concern to run simulations to help determine the best course of action while a disaster event is unfolding. It can also highlight the most effective prevention methods, and where the greatest vulnerabilities are for the specific region and threat.

Crowd-sourcing software Ushahidi (meaning “evidence” in Swahili) is another example of a useful tool for disaster or conflict management.

This free, open-source software is used at more than 100,000 communities globally.

During the 2007–2008 Kenyan election crisis, a local blogger put a callout online. The blogger was seeking someone with the technical skills needed to produce a combined image of where violence was happening, to then overlay it on a map.

With no shortage of volunteers, it wasn’t long before the platform was up and running. Soon the site was crowd-sourcing up to 40,000 first-hand, geotagged and time-stamped reports. It also drew from social media posts and news articles.

The system was able to send information back to individuals on the ground to help them avoid locations where violence is reported. All of this happened beyond the surveillance capabilities of the government, which means contributors remained safe from reprisal.

Looking to the future

Traditional bushfire prevention methods so far have included managing fuel loads with low intensity burns to reduce flammable vegetation and leaf-litter before they reach levels that result in destructive high-intensity.

While this method works where it is employed, it’s time we used 21st century solutions to tackle the increasing threat of bushfires. In many parts of Australia, the question is when a disaster will occur, not if it will.

Read more: Firestorms and flaming tornadoes: how bushfires create their own ferocious weather systems

First responders facing an advancing fire need all the help they can get, and strategically gathered information from smart systems will give our firefighters a distinct advantage.

The technologies discussed above are some of the ways we can rise to the challenge. We need to build stronger, more capable ways of preventing disaster where possible, managing the disaster while it happens, and identifying ways of becoming more disaster-resilient.

Review: Platform Papers 61: Criticism, Performance and the Need for Conversation, by Alison Croggon (Currency Press)

“Pay no attention to what the critics say”, quipped the composer Jean Sibelius in 1937, because “there has never been a statue set up in honour of a critic.”

Well, as music critic Alex Ross has observed, that’s not quite true, even if Ross does go on to conclude that the small number of statues to critics that do exist around the globe are merely “the exceptions that prove the rule”.

And yet, the work of a first-rate critic can be as important to the appreciation and understanding of a work of art (or performance) as our immediate experience of it.

Good critical writing can (among other things) prompt us to reflect on the quality (or otherwise!) of that experience, provide us with an historical context, and help draw our attention to the kinds of formal, social, political, and aesthetic content it might have.

A new platform paper by Melbourne-based novelist, poet and theatre critic Alison Croggon (Criticism, Performance, and the need for public conversation argues, indeed, that were critics to disappear from our public life altogether we would surely miss them.

And suggests that this is now a real possibility.

Croggon traces this threat to critics’ existence principally to the rise of online publishing and the recent decline in the business model of the print media.

While she observes that critics briefly found a vibrant new home for their writing on individual blogs, the more recent incorporation of such online content into consolidated internet platforms has led, she believes, to individual voices becoming submerged beneath a sea of SEO-optimised opining.

Such uncurated content, she argues, cannot replace what criticism used to do because it is no longer underpinned (or expected to be) by the sorts of expertise the professional critic of old once had.

Here, as elsewhere on the internet, commonly accepted distinctions between the value and function of expert and amateur commentary has all but dissolved into a commentary free-for-all.

In tracing why this might have happened, Croggon suggests that the “first effect of the digital revolution was the destablisation of hierarchies of taste”. It is possible, however, to trace this destablisation back much further.

Has postmodernism had a role?

A “postmodernist” notion arose in academic circles over at least the past half-century, for instance, which asserted that any value judgement we might make about an art object or performance is ultimately no more than the covert assertion of our own position of power or privilege.

Read more: Explainer: what is postmodernism?

It follows that there is therefore no innate value to be found in a particular aesthetic experience or object. What we take to be a good or bad work of art is really only the externalised expression of our own prejudices and tastes.

The internet has supercharged the impact of such an idea on our public discourse.

Search engines now quietly direct us to content that is favoured precisely because it confirms or, conforms to, what it knows to be our preexisting biases and interests, not because that content might be more authoritative or, indeed, true.

Good arts criticism, however, involves wielding expertise (such as a deep technical and historical awareness of the context and content of the art work under examination) in order that any judgements made by the critic are ultimately grounded in evidence and reason.

Merely expressing an opinion about a work of art is not the same as good arts criticism, but this is not the kind of distinction that a search engine can or will make for us.

The resultant failure of arts criticism to attract or maintain a large readership, and thus the financial backing of our major public and commercial media outlets, suggests to Croggon that “the biggest problem theatre criticism in Australia faces is simple economics”.

But I think that mistakes a symptom with its root cause, the concomitant devaluation of the “worth” of expert opinion in our public life more broadly.

We have instead allowed the marketplace itself to become be the primary determinant of the marketplace of ideas.

Limited in scope

Croggon’s essay does not explore this broader social context. It is limited both in scope (for instance, despite its title, it focuses almost entirely on theatre criticism) and in the breadth and depth of its analysis.

It also does not acknowledge the emergence of new platforms that do offer arts critics some protection from the ravages of unbridled marketplace logic.

One such platform is this one (although The Conversation’s academic contributors are not paid). Another is the arts pages of the Australian Book Review (to which I also occasionally contribute). The latter is supported by a grant from a cultural fund operated by The Copyright Agency and private philanthropy, which together enables it to publish a significant amount of suitably remunerated, long-form arts criticism.

Nevertheless, Croggon’s suggestion that we may need to consider more direct state subsidy of arts criticism, as we do of the arts themselves, is a worthy one.

She notes that in 2012, the ABC, recognising that it had a role to play in fostering diversity of authoritative critical voices, developed a platform called ABC Arts Online. Cuts to ABC funding, however, led to the cessation of this initiative in 2015. Two years later, the entire online archive of reviews was removed from public access.

Croggon is right to draw our attention to this lamentable state of affairs. And she is also right, more broadly, to encourage reflection and debate on the value and function of arts criticism in Australian public life.

Bushfires continue to burn across NSW and Queensland, the death toll has risen, and the damage to properties, wildlife and the environment is devastating. With conditions predicted to worsen over the summer, climate change has inevitably come into the frame.

The Prime Minister and Opposition leader have said policy arguments should be avoided until the immediate crisis has passed, but many – including former emergency chiefs and some victims – disagree. And Greens and Nationals have had vitriolic exchanges.

The Nationals David Littleproud has ministerial responsibility for water, drought, and natural disaster and emergency management. In this podcast, he says while “the man on the street” can link climate change and the bushfires, but “as elected officials, we’ve got a responsibility” to wait for the right time to have such discussions.

After announcing the government’s drought package last week, Littleproud criticises the states for not stepping up their efforts, and says they have done “three-fifths of bugger all”.

Animals are desperately vulnerable to natural disasters. An estimated 350 koalas have died during catastrophic bushfire conditions across eastern Australia and reports of injured animals continue to pour in.

It’s not just wildlife at risk. February’s Townsville floods claimed the lives of some 600,000 cattle. People are often injured while attempting to rescue pets, and the thought of leaving a dependent animal to face fire alone is devastating.

Read more: Drought and climate change were the kindling, and now the east coast is ablaze

The good news is there are already disaster management plans for animals in some states in Australia. Knowing about these plans can help you reduce the risk to your loved ones – human and otherwise.

Know your state’s rules

Since the 2009 Royal Commission into Victorian bushfires, New South Wales, Victoria, Western Australia and South Australia have adopted animal welfare plans for pets, livestock and wildlife.

Animal disaster management plans try to anticipate how the needs of animals will be managed in the event of a disaster. They assign roles to government agencies and non-government organisations to administer relief for animals.

During a disaster, however, animal owners remain responsible for them. A legal duty of care remains, although what that demands obviously changes during an emergency.

What about pets?

In NSW, people are advised to keep their pets with them in an emergency. Contained animals, such as dogs on a leash or cats in a carrier, may be taken to “animal friendly” evacuation centres.

Likewise, the Victorian plan directs councils either to ensure evacuation centres are equipped for animals or to advise people of alternative arrangements.

Unfortunately, SA and WA do not allow pets in evacuation centres (with the exception of assistance animals), meaning they must be housed outside or at a different location. Animal management plans in these states cite fairly vague “health and safety” reasons for the exclusion.

If you’re at any risk of future evacuation it’s vital you check whether your nearest relief centre can accommodate your pet. Even if you’re planning to stay with friends or family, unexpected circumstances may force you to spend some time at a relief centre.

Your disaster kit should contain pet food, registration and vaccination details, bedding, and any other equipment and medicine. You should also have a recent photo of your animal on your phone or printed out (puppy photos will not be useful in tracking down your adult dog).

State guidelines also urge pet owners to make sure your animals are properly vaccinated, microchipped, and wearing identification tags. Local councils, veterinarians, the RSPCA and Animal Welfare League are often designated points of contact when companion animals become lost in a disaster.

Livestock and horses

Livestock and large companion animals are obviously harder to manage than small pets. Disaster management guidelines recommend contacting relocation sites well before an emergency happens to arrange accommodation, and ensuring you have access to suitable transport ahead of time.

If you are unable to make advance arrangements – or if your plans have been disrupted – you can generally take large animals, such as horses, to your local evacuation centre for advice on your options.

If your animals cannot be moved off your property, the guidelines call for owners to move the animals to a low-risk area stocked with food and water for several days. Even if you plan to evacuate your horses or livestock, it’s a good idea to identify a suitable spot just in case.

Planning and guidance documents also stress that horses should be microchipped. The National Livestock Identification System may be used to track certain agricultural animals. They also arrange the distribution of emergency fodder following disasters.

Wildlife

Wild animals face unique challenges in disasters. They cannot be systematically evacuated and are highly dependent on natural habitat for their survival.

Animal emergency plans and guidance therefore tend to focus on providing relief to wild animals affected by disaster, relying on the contribution of charitable organisations.

The NSW plan identifies several partner wildlife rescue organisations, including WIRES, which is the state’s principal avenue for reporting injured wildlife. In SA, animal welfare organisations also lead relief efforts, whereas in Victoria, the government coordinates rescue and triage actions with support from volunteers.

In addition to relief services, holistic planning requires measures for preserving habitat and wildlife corridors. These reduce the risk of animal populations becoming isolated, and improve the availability of viable alternative habitat.

It’s a busy day at the office and your left eye has been twitching uncontrollably. So, out of curiosity and irritation you Google it.

Various benign causes — stress, exhaustion, too much caffeine — put your mind at ease initially. But you don’t stop there. Soon, you find out eye twitches could be a symptom of something more sinister, causing you to panic.

You ruin the rest of the day trawling through web pages and forums, reading frightening stories convincing you you’re seriously ill.

Read more: Curious Kids: why do some people worry more than others?

For many of us, this cycle has become common. It can cause anxiety, unnecessary contact with health services, and at the extreme, impact our day-to-day functioning.

But our recently published research, the first to evaluate online therapy for this type of excessive and distressing health-related Googling, shows what can help.

I’ve heard of ‘cyberchondria’. Do I have it?

The term “cyberchondria” describes the anxiety we experience as a result of excessive web searches about symptoms or diseases.

It’s not an official diagnosis, but is an obvious play on the word “hypochondria”, now known as health anxiety. It’s obsessional worrying about health, online.

Read more: Health Check: how do you know if you’re obsessed with your health?

Some argue cyberchondria is simply a modern form of health anxiety. But studies show even people who don’t normally worry about their health can see their concerns spiral after conducting an initial web search.

Cyberchondria is when searching is:

• excessive: searching for too long, or too often

• difficult to control: you have difficulty controlling, stopping or preventing searching

• distressing: it causes a lot of distress, anxiety or fear

• impairing: it has an impact on your day-to-day life.

If this sounds like you, there’s help.

We tested an online therapy and here’s what we found

We tested whether an online treatment program helped reduce cyberchondria in 41 people with severe health anxiety. We compared how well it worked compared with a control group of 41 people who learned about general (not health-related) anxiety and stress management online.

The online treatment is based on cognitive behaviour therapy (CBT), which involves learning more helpful ways of thinking and behaving.

Participants completed six online CBT modules over 12 weeks, and had phone support from a psychologist.

Read more: Explainer: what is cognitive behaviour therapy?

The treatment explained how excessive web searching can become a problem, how to search about health effectively, and practical tools to prevent and stop it (see a summary of those tips below).

We found the online treatment was more effective at reducing cyberchondria than the control group. It helped reduce the frequency of online searches, how upsetting the searching was, and improved participants’ ability to control their searching. Importantly, these behavioural changes were linked to improvements in health anxiety.

Although we don’t know whether the program simply reduced or completely eliminated cyberchondria, these findings show if you’re feeling anxious about your health, you can use our practical strategies to reduce anxiety-provoking and excessive online searching about health.

So, what can I do?

Here are our top tips from the treatment program:

• be aware of your searching: don’t just search on auto-pilot. Take note of when, where, how often, and what you are searching about. Keep track of this for several days so you can spot the warning signs and high-risk times for when you’re more likely to get stuck in excessive searching. Then you can make a plan to do other things at those times

• understand how web searches work: web search algorithms are mysterious beasts. But top search results are not necessarily the most likely explanation for your symptoms. Top search results are often click-bait – the rare, but fascinating and horrific stories about illness we can’t help clicking on (not the boring stuff)

• be smart about how you search: limit yourself to websites with reliable, high quality, balanced information such as government-run websites and/or those written by medical professionals. Stay away from blogs, forums, testimonials or social media

• challenge your thoughts by thinking of alternative explanations for your symptoms: for example, even though you think your eye twitch might be motor neuron disease, what about a much more likely explanation, such as staring at the computer screen too much

• use other strategies to cut down, and prevent you from searching: focus on scheduling these activities at your high-risk times. These can be absorbing activities that take your focus and can distract you; or you can use relaxation strategies to calm your mind and body

• surf the urge: rather than searching straight away when you feel the urge to search about your symptoms, put it off for a bit, and see how the urge to search reduces over time.

And if those don’t help, consult a doctor or psychologist.

The ABC has announced it will not provide live radio coverage of the Olympics for the first time in 67 years for budgetary reasons, and because Australians now have the “increased ability to access Olympics coverage in other ways”.

The decision sparked a furious response from some, such as veteran sports broadcaster Quentin Hull, who deemed it a “national shame”.

But was the decision a snub to sports fans in favour of other types of broadcasting, or just a matter of hard-nosed accounting?

Funding cuts forcing difficult decisions

The ABC’s decision needs to be viewed in two contexts: internal competition for increasingly scarce resources, and a battle to define how sport now fits into the ABC’s charter obligations.

First, the money. The ABC’s financial situation is in dire straits, especially given the range of services it is now expected to provide.

In the past two decades, the ABC has transformed from a radio and television broadcaster to a multi-channel media organisation. It’s done this to meet the responsibilities of its comprehensive service charter, ensuring it reaches Australians across a range of new digital platforms (three digital television channels, digital radio services, podcasts and apps).

At the same time, the government has frozen the ABC’s budget for three years from 2019, which comes on top of earlier budget cuts. The decision not to send a radio team to the 2020 Tokyo Olympics is a direct result of these cuts.

Read more: The ABC didn’t receive a reprieve in the budget. It’s still facing staggering cuts

Prior to the federal election in May, and the funding freeze, the ABC expected to receive an extra $14.6 million in indexed funding for 2019-20, sufficient to cover occasional events like the Olympics and the current bushfires.

Now, it faces an $84 million shortfall over the next three years instead.

There’s an added problem created by the annual approval of divisional budgets.

This year, ABC Radio’s budget would have needed special top-up funding to meet the cost of the Olympics. Sources have told me this is estimated to be $1 million (for the rights and production costs).

Given top-up funding is not available in the current budget, executives would have had to make program or staff cuts elsewhere. That’s on top of the cuts already planned as a result of the budget freeze. They chose not to.

Sports fans may be outraged the ABC has chosen to ditch its Olympic radio coverage instead, but cuts anywhere else – say to regular religious or children’s programming – would have produced equally loud protests from other audiences.

A long history of sports coverage

Which leads to our second question: what is the ABC’s role in providing sports coverage in a multi-platform world?

For decades, the ABC and its constituents saw sports broadcasting as central to its charter roles: universal service, national identity and innovation.

The first ABC Annual Report noted in 1933 that the “keen national interest in sport” had inspired daily broadcasts of the “Bodyline” Ashes cricket series to a national network of 12 stations. Indeed, the ABC helped build a national audience for sports such as cricket and tennis, first on radio, and then on television.

Read more: Into the spotlight: media coverage of the Paralympic Games has come a long way

According to ABC historian Ken Inglis, the broadcaster believed sports broadcasting was its “most characteristic feature”, directly linked to its role in nation-building.

Sports broadcasts, especially of the Olympics, have also been opportunities for the broadcaster to try new programming approaches and delivery technologies. For instance, the use of shortwave and relay services enabled coverage of the 1952 Summer Olympics in Helsinki – the first ABC Olympics coverage.

Yet, ABC sports broadcasting has always been contentious.

In 1948, ABC Chairman Richard Boyer argued to General Manager Charles Moses that there was too much sport on ABC Radio. Although Moses countered that these broadcasts brought audiences to the ABC, the “commission insisted that the time devoted to sport be reduced” and savings spent on other programs.

However, Boyer changed his mind somewhat after the ABC’s re-broadcast of the BBC coverage of the 1948 Olympics was widely criticised for focusing too little on Australian competitors.

In 1956, ABC’s coverage of the Melbourne Olympics became a major moment in Australian television, though for most Australians it was ABC Radio that ensured they were able to share in the event.

Decades later, when top-tier sports like cricket were being commercialised, the Dix Inquiry argued the ABC needed greater diversity in its sporting output, leading to increased broadcasts of women’s sport and the Paralympics from 1988.

However, less than a decade after battling SBS for the Ashes cricket rights in 2005, the ABC started to become more ambivalent about sports as a fundamental part of its charter activities. Since the early 2010s, ABC TV has moved almost completely out of sports.

ABC Radio, in contrast, had maintained a strong commitment to sports broadcasting throughout the 2000s – until now.

Where can Australians go now?

So, without the ABC’s involvement, will Australians still have audio access to the Olympics?

Southern Cross Austereo was earlier tipped to be in position to buy the commercial Olympic radio rights, following its coverage of the 2016 Rio Games.

Read more: ​The Coalition government is (again) trying to put the squeeze on the ABC

But as its parent company shares hit a five-year low in mid-October and it recently slashed jobs, there’s a chance it won’t follow suit for Tokyo. It’s not yet clear.

What is clear is that in the “anywhere, anytime, any device” age, radio is still important to many Australians. For people driving, exercising or working, radio remains a critical sports delivery platform.

The ABC has decided this will no longer be a priority. The question, then, is whether Australians who want to follow the Olympics on radio will have any options at all in 2020.

These days, not many Aussies consider the ibis a particularly admirable creature.

But these birds, now colloquially referred to as “bin chickens” due to their notorious scavenging antics, have a grandiose and important place in history – ancient Egyptian history, to be precise.

Using DNA from ibis mummies buried around 2,500 years ago, our research published today explores this bird’s stature in ancient times, and how it was reared.

Our findings suggest ancient Egyptian priests practised short-term taming of the wild sacred ibis. This was likely done somewhere in natural ibis habitats, such as local lakes or wetlands. Also, it was probably done close to the Thoth temple at Tuna el Gebel, in a bid to meet an ibis demand fuelled by religious burial rituals.

We’ve bin chicken out some DNA

The preservation of bodies through mummification is a hallmark of ancient Egyptian civilisation.

Unfortunately, unfavourable environmental conditions such as high temperatures, humidity and alkaline conditions often result in scepticism about the authenticity of genetic results from ancient Egyptian human remains.

Read more: Friday essay: the rise of the ‘bin chicken’, a totem for modern Australia

However, animal mummies in the region are much more common. And the sacred ibis, (Threskiornis aethiopicus), is by far the most common bird mummy in ancient Egypt’s underground catacombs, with more than two million found.

The Egyptian sacred ibis looks very similar to the Australian white ibis (Threskiornis molucca). We once thought they were both sacred ibises, but the two are actually sister species in the ibis family.

Our analysis of 14 sacred ibis mummies, which we collected ourselves from catacombs, helped reveal the role of this bird in ancient Egyptian society and religion.

We analysed and compared mitochondrial DNA, which is a section of DNA inherited from the mother and passed only through females. In doing so, we were able to compare the genetic diversity among the ancient ibis mummies to that of modern sacred ibis populations in Africa.

All hail the Ibis

Ancient Egyptians thought animals were incarnations of gods on Earth. They worshipped the sacred ibis as the god Thoth, which was responsible for maintaining the universe, judging the dead, and overseeing systems of magic, writing, and science.

It’s not surprising then, that professionally mummified Ibises were sacrificially offered to Thoth at his annually celebrated festival. In fact, offering sacred ibis mummies in ancient Egypt was a common practice between the 26th Dynasty (664-525 BC) and the early Roman Period (AD 250).

Read more: Mummies have had a bad wrap – it’s time for a reassessment

For ancient Egyptian priests, the mummification of animals like ibises was not simply a ritual duty, but also a profitable business. Considering the number of ibis mummies found, one has to wonder how the priests secured supplies for this practice.

Some evidence from ancient Egyptian text suggests the birds may have been raised in dedicated large-scale farms over the long term – either next to or within temple enclosures.

In the writings of the priest and scribe Hor of Sebennytos, from the second century BC, he reported regularly feeding about 60,000 sacred ibises with “clover and bread”. This could be interpreted as domestication, or controlled breeding.

In 1825, French naturalist Georges Cuvier described the skeleton of an ibis mummy from Thebes that he’d unwrapped, saying:

One sees that this mummy must have come from a domestic bird in the temples, because its left humerus was broken and reset. It is highly improbable that a wild bird with a wing broken would have been able to capture prey and escape predators. Hence it would have been unable to survive long enough to have healed.

Researchers today have also suggested the seasonal taming of ancient wild ibises, wherein the birds were reared over a single generation by priests, in natural habitats close to temples. Moreover, it seems they were not domesticated, which would have required breeding in captivity over many generations.

The rearing is thought to have occurred at locations such as the Lake of the Pharaoh, in which a natural basin was filled annually by flood waters from the Nile River.

These actions were almost certainly aimed at collecting a large number of adult birds, which were required for the Egyptian ritual of offering a mummified ibis to please Thoth.

1.75 million birds, then suddenly none?

Millions of sacred ibis mummies have been found stacked floor-to-ceiling along kilometres of dedicated catacombs in Egypt.

It’s believed that about 10,000 mummies were deposited annually in the Sacred Animal Necropolis at Saqqara.

Read more: A recipe for mummy preservation existed 1,500 years before the Pharaohs

This amounts to an estimated 1.75 million birds deposited at this location alone. Another catacomb at Tuna el-Gebel contains approximately four million sacred ibis mummies, the largest known number of any mummified birds at a single Egyptian site.

But these birds disappeared from Egypt around 1850, centuries after the cessation of the mummification practice. How and why they disappeared remains a mystery.

Clearly, the people of today treat the ibis in a very different way to the ancient Egyptians. For the latter, they were sacred birds that held a special place in society.

Perhaps we should remember that and recognise, at least a little, their honoured status in the past.

Parkinson’s disease is a progressive neurodegenerative disorder affecting one in 350 Australians.

It’s caused by the loss of cells deep within the brain that produce a neurotransmitter called dopamine. Degeneration of these neurons impairs the transmission of signals within the brain, affecting a person’s ability to control their muscles. Symptoms can include tremor, stiffness, slowness, and problems walking.

Read more: The sex gene SRY and Parkinson’s disease: how genes act differently in male and female brains

But many people with Parkinson’s disease also report troubling non-motor symptoms. These include depression, anxiety, psychosis, cognitive impairment, and addiction. These symptoms can be due to progression of the disease more widely within the brain, or can be side effects of treatment.

In our recently published research, we looked at why many people with Parkinson’s disease develop impulsivity (the tendency to act recklessly on the spur of the moment) and addictive behaviours, such as problem gambling or sex addiction.

Treatment

After diagnosis, the vast majority of people with Parkinson’s disease will take medication. The dose will generally increase over time as motor symptoms become more severe.

The mainstay of treatment is medication that restores depleted dopamine, called dopaminergic medication.

About one in six people treated with this medication will develop impulsive and addictive behaviours. These behaviours can include problem gambling, a preoccupation with sex or pornography, compulsive shopping or binge eating.

People who experience this phenomenon commonly describe “losing control” and being “driven” to engage in these behaviours against their better judgement, and despite significant interpersonal, financial and legal harms.

After an initial diagnosis of Parkinson’s disease, facing these problems can be a devastating second blow for patients and their families.

Our research

We’ve known for some time about the association between dopamine and addictive behaviours. As well as facilitating movement in our bodies, dopamine contributes to the experience of pleasure, and plays a role in learning and memory — two key elements in the transition from liking something to becoming addicted to it.

But scientists and clinicians have been unable to say exactly why some people develop addictive behaviours after taking dopaminergic medication, while others don’t. This limits our ability to provide a personalised approach to our patients when discussing these treatments.

Read more: From blood letting to brain stimulation: 200 years of Parkinson’s disease treatment

We hypothesised brain structure, which varies between different people, was a key factor in determining whether or not addictive behaviours would follow after people received dopaminergic medication.

The progression of Parkinson’s disease affects brain structure differently in different people, depending on the spread of neurodegeneration within the brain. If we could capture this variability, perhaps we could link this to impulsivity and addiction.

We took a group of 57 people with Parkinson’s disease on dopaminergic medication and focused on two brain networks thought to be crucial for decision making: a network for choosing the best course of action and a network for stopping inappropriate actions. These networks connect regions of the brain within the frontal lobes, an area known to support higher-order features of personality such as judgement.

We used an advanced method of brain imaging called diffusion MRI, which allowed us to visualise the structure of connections between the different brain regions involved in these circuits. Using this technology, we could quantify if the strength of these connections had been affected by Parkinson’s disease.

Alongside the brain imaging, we created a virtual casino for our participants. We measured their level of impulsive behaviours through their tendency to place high bets, switch between poker machines and accept “double or nothing” gambles.

In contrast to traditional pen and paper tests for assessing impulsivity and addiction, we felt the virtual casino would simulate an environment closer to real life.

We then compared behaviour in the virtual casino to the connectivity of the choosing and stopping networks, to see if there was an association.

Separate to this testing, we followed the participants in our neuropsychiatry clinic to see if they developed addictive behaviours.

What we found

For the most part, the greater the strength of the choosing network and the weaker the strength of the stopping network, the more impulsive participants were. That is, they had a greater tendency to behave recklessly in the casino environment by placing large bets, trying lots of different poker machines and making “double or nothing” gambles.

With regards to addictive behaviours, 17 of our 57 participants developed these problems during clinical follow up.

Read more: What causes Parkinson’s disease? What we know, don’t know and suspect

Addicted participants expressed impulsive gambling behaviour in the virtual casino, as we would have predicted. However, their brain structures suggested they would be conservative (that is, they had a weaker choosing network and a stronger stopping network). Further, the size of the dose of dopaminergic medication didn’t appear to influence reckless behaviour in these individuals.

This suggests the neurodegeneration associated with Parkinson’s disease elicits a difference in the way the brain works in these people with addiction.

What these results mean

Our method of combining information from brain imaging and virtual gameplay allowed us to distinguish these people, which has not previously been possible and could have significant implications for clinical practice.

As we begin to grasp commonalities in brain structure among people on dopaminergic medications who develop addiction, we hope to share this information to help patients and their families make the most informed choice about their treatment.

Predicting those at risk would involve the routine use of diffusion imaging and analysis in clinical practice. While this would generate extra health-care costs, it could reduce the costs and harms of addiction.

We could then select particular drugs in preference to others, or even bring forward advanced therapies such as deep brain stimulation, which treats motor symptoms with focused electricity rather than dopaminergic medication.

In the meantime, for people with Parkinson’s disease taking dopaminergic medication, establishing a network of support from family and health professionals who can detect the early warning signs of addictive behaviours is important in limiting the long-term harms of addiction.

The concept of “home” refers to more than bricks and mortar. Just as cities are more than buildings and infrastructure, our homes carry all manner of emotional, aesthetic and socio-cultural significance.

Our research investigates music and sound across five settings: home, work, retail spaces, private vehicle travel and public transport.

Read more: Contested spaces: you can’t stop the music – the sounds that divide shoppers

We found our interview subjects often idealised home along the lines of what Rowland Atkinson terms an “aural haven”. He suggests, although “homes are … rarely places of complete silence”, we tend to imagine them as “refuge[s] from unwanted sound” that offer psychic and perceptual “nourishment to us as social beings”.

We explored the ways in which people shape and respond to the home as a set of “modifiable micro-soundscapes”. Through 29 in-depth interviews, we examine how people use music and sound to frame the home as a type of “interaction order”. Erving Goffman coined this term to capture how people respond to the felt “presence” of an other.

That presence can be linguistic or non-linguistic, visual or acoustic. It can cross material thresholds such as walls and fences. Goffman wrote:

The work walls do, they do in part because they are honoured or socially recognised as communication barriers.

Cultivating sonic havens through music

As we detail in our recent essay in Housing, Theory and Society, the type of listening that most closely matches the idea of the home as an aural haven is bedroom listening – by young people in particular. We found that, as well as offering “control” and “seclusion”, the bedroom gave listeners a sense of “transcendence” and immersed them in “deep” listening. One interview subject said:

When I get a new album … I like to experience [it] by … lying down on the floor… I’ll turn the lights off and I’ll just be engaging with the music, my eyes won’t be open.

Another reported putting on headphones to listen to special selections of music, despite not needing to. “Headphones… [is] a more intimate … kind of thing”, even in a bedroom setting.

Read more: Our brain-computer interfacing technology uses music to make people happy

When it came to music in shared spaces and in relation to neighbours, our interview subjects seemed both aware of music’s visceral powers and keen to respect the territorial or acoustic “preserves” of others. One young female sharing a house with her mother carefully curated the type of music played, and what part of the house it was played in. Her choices depended on whether her mother was home and whether she had shown interest in particular genres.

All respondents who lived in shared households expressed some kind of sensitivity to not playing music at night.

Another lived by herself in an apartment complex of five. She took deference towards neighbours seriously enough to “tinker away” on her piano only when she was sure her immediate neighbour wasn’t home. She “didn’t play the piano much” inside her flat and was only prepared to “go nuts” playing the piano in halls and other non-domestic settings.

Music as a bridging ritual

Another of our findings accorded with the microsociological focus on how people organise time and space in everyday life. We found evidence, for example, of how music was used to wake up, or to transition to the weekend, or as a “bridging ritual” between work and home.

One interview subject remarked that he is “dressed casually anyway” when he returns from work, so his mechanism for shifting to home mode is to listen “to music … pretty much as soon as I get home … unless I’m just turning around and going straight somewhere else”. In other words, he associated the boundary between home and non-home with music and the listening rituals of returning home.

Read more: Like to work with background noise? It could be boosting your performance

One of the themes in academic literature about media and the home is that electronic and digital media blur the boundary between the inside and outside of the home. There is no doubt radio, television and now various digital platforms bring the world “out there” into the immediacy and intimacy of our own domestic worlds. But, as Jo Tacchi noted of radio sound, those sounds can also be used to weave a sonic texture of domestic comfort, security and routine.

We also found interesting sonic continuities between our homes and how we make ourselves at home in non-domestic settings. As Christina Nippert-Eng writes:

Locked in our cars, commutes offer the working woman or man the legitimate equivalent of a teenager’s bedroom, often complete with stereo system and favourite music.

In short, sonic havens are simply “places where we can retreat into privacy”, inside or outside our literal homes.

The deal to crank up Adelaide’s desalination plant to make more water available to farmers in the drought-stricken Murray-Darling Basin makes no sense.

It involves the federal government paying the South Australian government up to A$100 million to produce more water for Adelaide using the little-used desalination plant.

The plant was commissioned in 2007 at the height of the millennium drought. It can produce up to 100 gigalitres of water a year – enough to fill 40,000 olympic sized swimming pools. But has been used sparingly, operating at its minimum mode of 8 gigalitres a year, because of the expense of turning seawater into freshwater.

Adelaide has continued to mostly draw water from local reservoirs and the River Murray, which on average has supplied about half the city’s water (sometimes much more).

But with federal funding, the desal plant will be turned on full bore. This will free up 100 gigalitres of water from the Murray River allocated to Adelaide for use by farmers upstream in the Murray Darling’s southern basin.

The federal government expects the water to be used to grow an extra 120,000 tonnes of fodder for livestock. The water will be sold to farmers at a discount rate of A$100 a megalitre. That’s 10 cents per 1,000 litres.

By comparison, the residential price for that water in Adelaide would be A$2.39 to A$3.70 per 1,000 litres.

The production cost of desalinated water is about 95 cents per 1,000 litres when there’s rainwater already stored, according to a cost-benefit study published by the SA Department of Environment and Water in 2016. That means the total cost for the 100 gigalitres will be about A$95 million.

So the federal government is effectively paying A$95 million to sell water for A$10 million: a loss to taxpayers of A$85 million.

What do we get for the money?

The discounted water provided to individual farmers will be capped at no more than 25 megalitres. The farmers must agree to not sell the water to others and to use it to grow fodder for livestock.

There are many different forms of fodder but livestock producers most favour lucerne hay because it is highly nutritious. But it is also more expensive than cereal, pasture or straw hay.

The amount of hay that can be grown with a megalitre of irrigation water depends on many things, but 120,000 tonnes with 100 gigalitres is possible in the right conditions.

In the Murray-Darling southern basin lucerne hay currently sells for A$450 to A$600 a tonne. That would make the market value of 120,000 tonnes of lucerne A$54 million to A$72 million.

It means, on a best-case scenario, the federal government will be spending A$85 million to subsidise the production of hay worth A$72 million to its producers.

The reality of farming

In practice farms and farmers are incredible diverse, so not all irrigators will necessarily grow lucerne. Alternative fodders such as pasture or cereal hay generally have much lower market values. Which meaning the value of the fodder produced may be much less than the best-case scenario.

It’s worrying that this policy shows such little regard for farming realities. It appears to have been crafted on the premise that every farmer has the same land, the same equipment and the same needs.

Dictating the water must be used for a single purpose runs counter to the needs of the agriculture sector. If farmers could put it to a more effective use, why not allow it?

In addition, it’s not clear how all the monitoring will be done to maintain compliance over such a restrictive regime.

What measures will prevent farmers buying the discounted water and then simply selling an equivalent amount of any carry-over allocation at the going rate of up to $1,000 a megalitre?

Read more: Drought and climate change are driving high water prices in the Murray-Darling Basin

How will the government distinguish between the fodder grown with the 25 megalitres provided at low cost and any other fodder harvested on the same farm? How much will it cost to monitor and enforce such arrangements?

The difficulty of answering these types of questions is precisely the reason why countries in the former eastern bloc failed to adequately provide for their populations. Telling people what crop to grow, when to grow, how to water the crop and how it should be consumed has not worked in the past. Farm businesses that respond to prices and use inputs, including water, in a way that suits their long- term commercial needs are generally better off.

It seems a long way from the type of national drought policy Australia needs. It’s hard to see how a policy of this kind does anything other than waste a large amount of public money and disrupt important market mechanisms in agriculture in the process.

When thinking of sexbots, companionship might not be the first word that comes to mind. But sexbot advertising promises more than sex toys. It is also selling emotional intimacy: robots marketed as if they are capable of meeting both physical and psychological needs.

They are being sold as a solution to loneliness.

Sex robots started to come on to the market around 2010. Those available now have skin that is claimed to feel lifelike, heated orifices, and the ability to groan on touch. They may have customisable eye colour, skin tone, hair styles, orifices and accents. A 2017 survey suggested almost half of Americans think that having sex with robots will become a common practice within 50 years.

The British distributor of one such robot, “Samantha”, even argues aged care homes would benefit from adopting sexbots, saying, “If people had a companion and a sex aid in a Samantha, that would take massive pressure off carers and nurses.”

Read more: Sex robots are here, but laws aren’t keeping up with the ethical and privacy issues they raise

Our desires beyond sex

My research seeks to understand companionship between humans and sexbots. I examine sex robots as objects that humans have created to fill a void, which also reflect cultural understandings of human relationships.

A companion might be a trusted friend, a spouse, a short-term sexual partner, or a pet. Recently, sex workers have used #companion in social media posts as a way of avoiding censorship. But for the most part, when we use the phrase companionship we use it to refer to a long-term, sharing relationship.

The sexbot Roxxxy is made by engineer Douglas Hines, the owner of a New Jersey-based company that is called True Companion. Hines claims “sex only goes so far – then you want to be able to talk to the person”. Programmed with six personalities including Frigid Farrah and Wild Wendy, Roxxxy can also be further customised with apps. True Companion’s demonstration video opens with the question: “What if I could have my true companion? Always turned on and ready to play.”

Another sexbot, Emma, was created by the Chinese AI Shenzhen All Intelligent Technology Company Ltd (also known as AI-Tech or AI Technology). On the company’s website, she is marketed as a “real AI you can talk to.” She offers “warm hugs” and will “feel your feelings.” At the same time, she is advertised with a vagina that is 18cm deep and an anus that is 16cm deep.

The robot, “Harmony”, produced by RealdollX, an American firm, has advanced artificial intelligence that allows her to hold conversations, remember details, and tell jokes.

The manufacturers have keenly focused on the detail in her facial appearance and movement. She has the most advanced facial movement of sex robots to date, including the ability to blink and move her lips with speech.

Just one of the family?

In 2017, British based sexbot distributor Arran Lee Wright described his relationship with Samantha. In a TV interview, Wright called Samantha a “supplement to help people enhance their relationships” – not only couples, but as part of the family.

In “family-friendly” mode, sexbots are restricted from blurting out overtly sexual comments, and Wright claimed his children (then aged three and five) were fond of Samantha. The morning show hosts were outspokenly uncomfortable about this relationship.

While Wright talked about the place of Samantha in his family, Emma is marketed as a means to negate loneliness: she is the perfect girlfriend. A girlfriend to have picnics with; who can translate emails, remind you to take an umbrella, wake you up on time and tell you how great you are.

These claims of companionship are, of course, an exaggeration. The robot Emma cannot move itself, walk, or eat. Part of being in a relationship – familial or romantic – is the way we partake in everyday routines that make up important shared aspects of human lives.

And despite the tone of these ads, the imagery in the marketing of Emma is sexualised and reminiscent of soft-core pornography. She is clearly addressed to a hetrosexual man. She might be marketed as a companion, but she is a companion for a very specific demographic.

Artificially intelligent soulmates

The existence of robot pets such as Aibo and Paro shows that humans can experience emotional satisfaction from robot-human relationships. A pet robot baby seal has been found to calm people suffering from dementia and a child robot has supported children on the autism spectrum.

However, relationships between humans and pets differ from human to human ones. The power dynamic is different. Emma is presented as equal to human, but is submissive in the marketing. Social interaction is limited. Her passive gaze does not interact with the viewer. She remains a disempowered body that can only be gazed upon.

The unequal power balance in human/pet relationships might be a factor in the success of robot pets. And is not impossible some people might find a form of companionship in sex robots, but with current technical limitations, they can’t equate to the experience of human/human relationships.

Our fears and fascination with erotic objects can tell us a lot about cultural understandings of sexuality, companionship and technology. Humans look to technology as a solution to our own imperfections and struggles.

So perhaps the question isn’t can sexbots be companions, but what is a companion? And, can a solution to loneliness be bought?

New South Wales and Queensland are in the grip of a devastating bushfire emergency, which has tragically resulted in the loss of homes and lives.

But the smoke produced can affect many more people not immediately impacted by the fires – even people many kilometres from the fire. The smoke haze blanketing parts of NSW and Queensland has seen air quality indicators exceed national standards over recent days.

Studies have shown there is no safe level of air pollution, and as pollution levels increase, so too do the health risks. Air pollution caused nine million premature deaths globally in 2015. In many ways, airborne pollution is like cigarette smoking – causing respiratory disease, heart disease and stroke, lung infections, and even lung cancer.

Read more: Firestorms and flaming tornadoes: how bushfires create their own ferocious weather systems

However, these are long-term studies looking at what happens over a person’s life with prolonged exposure to air pollution. With bushfire-related air pollution, air quality is reduced for relatively short periods.

But it’s still worth exercising caution if you live in an affected area, particularly if you have an existing health condition that might put you at higher risk.

Air quality standards

The exposure levels will vary widely from the site of the fire to 10 or 50 kilometres away from the source.

The national standard for clean air in Australia is less than 8 micrograms/m³ of ultrafine particles. This is among the lowest in the world, meaning the Australian government wants us to remain one of the least polluted countries there is.

8 micrograms/m³ refers to the weight of the particles in micrograms contained in one cubic meter of air. A typical grain of sand weighs 50 micrograms. When people talk about ultrafine particles the term PM, referring to particulate matter, is often used. The size of PM we worry the most about are the small particles of less than 2.5 micrometres which can penetrate deep into the lungs, called PM2.5.

To put this in perspective, Randwick, a coastal suburb in Sydney which was more than 25km from any of the fires yesterday, had PM2.5 readings of around 40 micrograms/m³. Some suburbs which sit more inland had readings of around 50 micrograms/m³. Today, these levels have already reduced to around 20 micrograms/m³ across Sydney.

We’re seeing a similar effect in Queensland. Today’s PM2.5 readings at Cannon Hill, a suburb close to central Brisbane, are 21.5 micrograms/m³, compared with 4.7 micrograms/m³ one month ago.

A number of health alerts were issued for areas across NSW and Queensland earlier this week.

While these numbers may seem alarming compared to the 8 microgram/m³ threshold, the recent air pollution in India’s New Deli caused by crop burning reached levels of 900 micrograms/m³. So what we’re experiencing here pales in comparison.

Bushfire smoke and our health

However, this doesn’t mean the levels in NSW and Queensland are without danger. Historically, when there are bushfires, emergency department presentations for respiratory and heart conditions increase, showing people with these conditions are most at risk of experiencing adverse health effects.

Preliminary analysis of emergency department data shows hospitals in the mid-north coast of NSW, where fires were at their worst, have had 68 presentations to emergency departments for asthma or breathing problems over the last week. This is almost double the usual number.

Read more: After the firestorm: the health implications of returning to a bushfire zone

One study looked at the association between exposure to smoke events in Sydney and premature deaths, and found there was a 5% increase in mortality during bushfires from 1994 to 2007.

But it’s important to understand these deaths would have occurred in the people most vulnerable to the effects of smoke, such as people with pre-exsisiting lung and heart conditions, who tend to be older people.

For people who are otherwise healthy, the health risks are much lower.

But as the frequency of bushfires increases, many scientists in the field speculate these health effects may become more of a concern across the population.

How to protect yourself

If you’re in an affected area, it’s best to avoid smoke exposure where possible by staying indoors with the windows and doors closed and the air conditioner turned on.

If you are experiencing any unusual symptoms, such as shortness of breath or chest pain, or just do not feel well, you should speak to your health care professional and in an emergency, go to hospital.

Read more: How rising temperatures affect our health

Once the fires have been put out, depending upon the region, local weather conditions and the size of the fire, air quality can return to healthy levels within a few days.

In extreme situations, it might take weeks or months to return to normal. But we are fortunate to be living in a country with good air quality most of the time.

More than 600 schools have been closed, and some damaged, in recent days as bushfires rage across Queensland and New South Wales. Some students have been urgently evacuated while in school. People have lost homes and animals and are experiencing significant distress.

Research shows somewhere between 7% and 45% of children suffer depression after experiencing a natural disaster. Children more at risk of depression include those who were trapped during the event; experienced injury, fear, or bereavement; witnessed injury or death; and had poor social support.

The Victorian Education Department commissioned us after the 2009 Black Saturday fires to train teachers in seven fire-affected regions in methods to foster resilience in children.

Read more: Mr Morrison, I lost my home to bushfire. Your thoughts and prayers are not enough

Teachers told us their students had experienced distressing emotions including high anxiety, fear and even panic during the event. Comments from teachers included:

Their world had changed forever; they became more fearful.

Some children were very frightened and for a long time stayed close to their parents.

Many children became scared and anxious about worldwide issues.

Their anxiety was triggered by the smell of smoke, a fire engine’s siren or a foggy day.

The teachers we interviewed also noted children’s profound sense of loss (of their homes, pets and livestock). Many students knew someone who had lost a family member or friend.

One teacher said:

The fires opened students’ eyes to what a disaster is. Not just something you see on TV.

We trained teachers using our Bounce Back program – a research-based social and emotional learning program first published in 2003. Most children are resilient and will bounce back quickly. Only a small minority may be at risk of ongoing anxiety and there are ways to minimise that risk.

How to help kids cope now

Try to stay calm and reassuring. Children take cues from the adults in their lives. If adults show fear and nervousness, children tend to mirror these emotions.

Try to focus on the small positives such as “we are all safe”. You can list the things that haven’t changed, such as your children’s friends. Reassure them other people such as family, friends, teachers and their community will help and that life will return to normal.

Everyone feels sad, anxious or upset when a bushfire burns near their home. By helping your child name their feeling, you are helping them feel more in control. Here are five steps to encourage your children to do this:

1. take notice when your child is feeling sad, frightened, angry or upset
2. encourage your child to talk about what’s troubling them, and listen and show you understand how they are feeling
3. name the emotion in words your child can understand – are they “worried”, “scared”, “a bit frightened” or “sad”?
4. help your child understand it’s normal to feel that strong emotion and help them to sit with their feelings
5. finish with a hopeful or optimistic statement they can do something to help make things feel better. This may include something physical (such as going for a walk or throwing a basketball through a hoop), something that creates positive feelings (like playing with a pet or friend, or drawing), or doing something kind or helpful for someone else.

Resilience is the capacity to bounce back after hardship.

To help your child bounce back, you can communicate that:

• life is mainly good but now and then everyone has a difficult or unhappy time
• although things aren’t good now and it might take a while to improve, it’s important to stay hopeful and expect things to get better
• you will feel better and have more ideas about what to do if you talk to someone you trust about what’s worrying or upsetting you
• unhelpful thinking (“our family will never get a nice home again”) isn’t necessarily true and makes you feel worse
• helpful thinking (“it might take a while to get our home back again but it will happen”) makes you feel better because it is more accurate and helps you work out what to do.

Coping after the event

Children with strong emotional support, such as from family and friends, are better able to cope with adversity.

Friendships may be disrupted after bushfires because of family relocations. Helping children connect via social media or phone with friends can reduce their sense of isolation.

Getting children back to school and regular routines can be one of the best ways to help their resilience.

Teachers are encouraged to allow time for children to talk about the bushfires and their feelings about them during class.

The teachers who participated in the Bounce Back program after Black Saturday explicitly taught children the skills for being optimistic and resilient – such as to challenge their unhelpful thinking and understand everybody, not just you, experiences setbacks sometimes.

They also taught kids skills for regulating their emotions and everyday courage to face their fears.

They used circle-time discussions of picture books and media stories to allow them to talk about their own experiences in a safe way.

Read more: ‘It’s real to them, so adults should listen’: what children want you to know to help them feel safe

We held focus groups with children of different ages in five of the primary schools that used our Bounce Back program. The children told us they: “know now what to do when something goes wrong”; “focus on more positives”; “don’t think the worst now”; “know things change”; “have learnt that sometimes you just have to put up with it”; and “now feel it’s easier to get back up in bad times”.

While a disaster can be challenging for children, a supportive home and school environment, together with coping skills, can help children recover reasonably quickly and get back to normal life.

Bushfire writing has long been a part of Australian literature.

Tales of heroic rescues and bush Christmases describe a time when the fire season was confined only to summer months and Australia’s battler identity was forged in the flames.

While some of these early stories may seem melodramatic to the modern reader, they offer vital insights into the scale and timing of fires and provide an important counterpoint to suggestions from some politicians this week that Australia’s fire ecology remains unchanged in the 21st century.

Read more: Mr Morrison, I lost my home to bushfire. Your thoughts and prayers are not enough

A contender for the first fictional representation of an Australian bushfire is Mary Theresa Vidal’s The Cabramatta Store (1850). Although she does not specify a month, Vidal is very clear regarding the season and the oppressive, sweltering heat:

It was one of the hottest days of an unusually hot and dry Australian summer. No breeze stirred the thin, spare foliage of the gum-trees, or moved the thick grove of wattles which grew at the back of a rough log hut.

Vidal’s account of the bushfire that ensues is evocative and intense:

The tall trees were some of them red hot to the top; the fire seemed to run apace, and every leaf and stack was so dry there was nothing to impede its progress.

Postcards from Australia

Vidal was not alone in treating fire as a fleeting, one-off incident. Other early accounts, such as Ellen Clacy’s 1854 romance story A Bushfire, or the prolific novelist William Howitt’s A Boy’s Adventures in the Wilds of Australia of the same year follow Vidal in depicting the bushfire as an isolated catastrophe.

Howitt’s novel takes the form of a notebook kept by Herbert, a recent young migrant, who recounts the wonder of his new life in the Bush. Though he doesn’t experience a fire at first-hand, Herbert regales the reader with another family’s bushfire adventure in lieu of his own. Yet in closing his account, dated January 14, he writes:

I wonder whether, after all, I shall see a bush-fire. During the last week we have seen lurid smoke by day, and a deep-red cloud by night … immense fires are raging in the jungle.

For Herbert, surviving a bushfire is a settler rite of passage and again, the dating of his entry emphasises the fire as a uniquely summer concern. The boyish narrator, though, cannot appreciate the trauma and severity of Antipodean fire.

An annual event

Over time, the settler community began to understand fire as a recurring phenomenon and the tone of fire stories shifted from a triumphant celebration of settler endurance, to a more brooding acceptance that the flames would return another year.

So season-bound was this understanding, a sub-genre of bushfire fiction emerged: the Christmas fire story. These works responded to the Victorian enthusiasm for yuletide tales, while at the same time highlighting the often horrific seasonal tribulations of bush-dwellers.

While there are many examples of Christmas fire stories, one of the best-known is Anthony Trollope’s novella Harry Heathcote of Gangoil (1874).

The plot, which takes place in the sugar-growing region of Queensland, revolves around the protagonist Harry’s deep fear of fire. Trollope highlights the hostility of the climate, the dangers posed by deforestation, and the deep-rooted anxieties that haunted migrant farmers each summer.

There are countless other works that allow us to map the Victorian era fire season.

Henry Kingsley’s sprawling 1859 novel The Recollections of Geoffry Hamlyn begins with another date reference:

Near the end of February 1857 … it was near the latter end of summer, burning hot, with the bushfires raging like volcanoes on the ranges, and the river reduced to a slender stream of water.

Once again here, the date identifies fires specifically with the summertime.

Climate emergency fiction

While 19th century fire stories offer a date-stamped and clearly defined fire season, today’s novelists work with a much less predictable set of environmental conditions.

The backdrops for the crime novelist Jane Harper’s thrillers The Dry (2016) and The Lost Man (2018) are tinder-dry rural communities, where years of drought mean fire could erupt at any moment.

Realist writing is capturing changing conditions, just as it did for settlers more than 150 years ago. Australia may always have been the “continent of fire”, as historian Tom Griffiths terms it, but literature shows us those fires are more prolific and less predictable now than ever before.

It’s five years since government worker Glen Turner was murdered by a farmer in a confrontation over land clearing laws. Media reporting after his death frequently propagated the image of the “poor farmer” at the mercy of laws enforced by out-of-touch city elites.

This narrative of an urban-rural divide reared its head again in recent days, when Nationals leader Michael McCormack derided “inner-city raving lunatics” who linked the bushfire crisis to climate change. Such rhetoric may appeal to a conservative party base or media audience, but does little for rural communities in the long run.

As farmers face the ever-worsening impacts of drought and climate change, strong environmental protections are required to protect water and other resources. We must better understand how divisive narratives, often serving political interests, are devised and dispersed.

Nowhere is this narrative more frequently rolled out than in northwest New South Wales, where tensions over land clearing have triggered a complex interplay between the media, farmers and politicians – fuelled by the tragedy of Turner’s murder.

Land clearing is a hot-button issue

Land clearing is a serious global environmental concern, and eastern Australia is one of the world’s deforestation hotspots.

However, regulations to limit land clearing have long been opposed by farmers who say they affect profitability. This message has been politically potent in NSW, and in 2016 legislative reform removed key checks on native vegetation clearing.

Read more: Our nature laws are being overhauled. Here are 7 things we must fix

In the state’s northwest, native vegetation and koala habitat is at risk of extinction due to land clearing. Broad-acre farm machinery and technology works best in large, flat paddocks uninterrupted by trees. The high costs of these technologies feed the economic pressure to cultivate increasing areas of land.

But as climate change and drought increasingly bring dust storms, bushfires and water shortages to rural areas, natural resources such as water, soil and vegetation have never been more valuable.

Latte sippers vs poor farmers

Turner’s murder by farmer Ian Turnbull occurred at Coppa Creek in northwest NSW, in the shadow of pending reforms to environment laws. In the days afterwards, rural politicians publicly expressed outrage at land-clearing regulations and claimed Turner’s death was “brought about by bad legislation”.

Media reports in the period between the murder and Turnbull’s sentencing were essentially a de facto trial of the legitimacy of land-clearing laws. Several sources implied that the compliance regime was somehow to blame for Turner’s death. These results supported findings by Amnesty International and Global Witness that weak enforcement of environmental law increases the risks to those who work on the frontline of land-use conflicts.

The media narrative fed on a supposed contest between biodiversity and agricultural production. Some coverage drew on libertarian notions of property rights and autonomy to justify resistance to the law. This includes radio broadcaster Alan Jones, who reportedly told listeners that environment officials enforcing native vegetation laws displayed “the kind of behaviour that leads people to murder”.

A complicit media

In recent months, landholders in northwest NSW engaged a public relations company to launch a campaign to have historic land-clearing charges dropped.

The PR onslaught included recruiting 2GB radio presenter Ben Fordham to the cause and lobbying key NSW National Party figures John Barilaro and Adam Marshall.

In July this year, Fordham said struggling farmers penalised for cleared vegetation on their farms were being forced off their land, reportedly telling listeners:

They are facing the prospect of fines of a million dollars, and having land locked up for 100 years. They face fines of A$13,000 for every day they refuse to answer questions. Talk about bullies!

The state government has since announced an amnesty for hundreds of farmers who faced penalties under old land-clearing laws. It is logical to assume the farmers’ campaign, and its emphasis on city-country tensions, influenced the government’s decision.

But the divisive rhetoric, and the resulting government decision, does not serve farming communities and comes at the cost of a sound balance between production and conservation.

We must do better

Better understanding of how narratives of legitimacy and resistance are constructed is important for environmental policymakers around the world. This is especially true as climate change threatens social and economic conditions.

Rural communities need environmental regulation that acknowledges their existential concerns, such as access to water, arable land and economic markets. The broader Australian public need regulation that finds the best balance between production and environmental values.

In 1992, state and federal governments committed to a national strategy for ecologically sustainable development that “improves the total quality of life, both now and in the future, in a way that maintains the ecological processes on which life depends”.

We aren’t there yet. Political will can either help achieve these aims, or obstruct progress by stoking city-country tensions.

Note: A coronial inquest into the circumstance surrounding the death of Glen Turner was announced in 2017 but is yet to be held.

Australians woke to the news last weekend that a 19-year-old Warlpiri man had been shot and killed by a police officer in Yuendumu, 300km north-west of Alice Springs.

A confrontation had occurred after two officers went to a property to arrest the man for breach of a condition of his suspended sentence. One report said the man lunged at the police officer as the pair approached him. Acting deputy commissioner Michael White said:

During that time a struggle ensued and two shots were fired and [the young man] sadly passed away later.

The community outrage has been swift, with a crowd of Yuendumu residents rallying outside the police station, demanding justice. The matter has now been classified as a death in custody.

Why is this still happening in modern Australia? Surely police have learned lessons from past tragedies, and they’re trained today to use their guns as a last resort. After all, they have tasers and other non-lethal weapons, don’t they?

In attempting to answer these questions, it’s useful to make some observations about current police practice and the available research.

Most Australian police officers carry guns

The first observation about last weekend’s tragedy is a simple one. Firearm deaths occur in heated situations because police carry guns as standard issue.

In 1970, only the New South Wales Police Force was habitually armed. Over time, policies were introduced in each Australian jurisdiction that allowed police officers to gauge their own level of vulnerability and request a firearm in circumstances they perceived as dangerous. As the years passed, this became a very subjective assessment.

The consequence of this policy of accretion is that firearms are now carried by most patrol officers in all Australian states and territories most of the time.

Read more: Victorian police have ‘shoot to kill’ powers when cars are used as weapons: here’s why this matters

Police direction on “shoot to kill” is clear. An officer can use lethal force against another person when there’s a reasonable threat of death or serious injury to the officer, another officer or a member of the public. The difficulty is in determining the reasonableness of the threat. In the heat of the moment this, too, involves a highly subjective assessment.

So does the routine arming of police make the public safer? Yes and no.

A civilian is 14 times more likely to be shot and killed by a police firearm in the US than by a police firearm in Australia, and 42 times more likely to be shot and killed by a police firearm in the US than by a police firearm in Germany.

But police in all three nations routinely carry firearms. So, the mere arming of police doesn’t appear to be the key factor in civilian deaths. There must be something more at play.

Best practice for firearms training

There is. The research tells us the number of civilian deaths caused by police firearms varies according to four important factors: the extent of police militarisation; the rules that pertain to the use of lethal force; the standards of firearms training; and the gun culture in the society in which officers operate.

The most important one for Australian policymakers is the third of these: the standards of firearms training.

To that end, five key imperatives for firearm training emerge from the research:

1. Australian police policies must have clear and precise rules regarding the carriage and drawing of firearms, and there must be high standards of accountability for those who carry and draw them
2. uniform firearms training must be across all jurisdictions
3. this training must include best practice communication techniques such as negotiation skills and deescalation strategies, and clear instructions regarding non-lethal alternatives
4. strong collaborations must be in place between police and health professionals and other social services
5. body cameras should be compulsory on all operational officers.

If these initiatives and practices are in place, and entrenched, one can safely assert that fewer deaths at the hands of police will occur.

Police are employed to protect us. If that does not happen, such as in Yuendumu, then there’s something going wrong in our police training centres.

Firearms make police officers feel safer

There will be a coroner’s inquest into the young man’s death. It’s too early to say what evidence will be offered and what the consequences might be. But the coroner will not rule that deadly force can never be used.

As you might recall, the Lindt cafe siege coroner was told the sharp-shooter who had the murderer in his sights in December 2014 was directed not to use lethal force, a decision that may have had fatal consequences.

Yes, police today are trained to use their guns as a last resort. And yes, they have tasers and other non-lethal weapons at their disposal. But in the heat of the moment, with the lives of serving officers potentially on the line, judgements are made quickly. Hindsight is a wonderful thing, but it is never available when it is needed most.

So what does the evidence tell us about firearms and the safety of police officers themselves? Available research suggests there is no clear evidence guns make police safer, but officers feel safer with firearms at their disposal.

And what of the future? There is no going back to the days when police did not carry guns. So the training associated with their use needs to be unremitting. Australian lives are relying on it.

New Zealand is ranked the third-most-wasteful country in the OECD. New Zealanders produce five times the global daily average of waste per person – and they are getting more wasteful, producing 35% more than a decade ago.

These statistics are likely to get worse following China’s 2018 ban on imports of certain recyclable products. China was the world’s top importer of recyclable plastics, but implemented the ban because it could no longer safely manage its domestic and imported waste. Unsurprisingly, in 2015, China was named the top source of marine plastic pollution in the world.

Since the Chinese market closed, 58% of New Zealand’s plastic waste now goes to Malaysia, Indonesia, the Philippines, Thailand and Vietnam — all countries with weak regulations and high rankings as global sources of marine plastic pollution.

Waste-to-energy (WtE) incineration has been raised as a solution. While turning plastic waste into energy may sound good, it creates more pollution and delays a necessary transition to a circular economy.

Read more: We need a legally binding treaty to make plastic pollution history

Dirty plastics

Shipments of plastic recycling often arrive in developing countries unsorted and contaminated. Materials that cannot be easily recycled are commonly burned, releasing dioxins into air, soil and water. In response, South-East Asian countries have started returning dirty plastics to developed countries.

Several New Zealand councils have stopped collecting certain plastics for recycling offshore. They are sending them to landfill instead. Available data suggest that even before the China ban plastics made up roughly 15% of the waste in municipal landfills – about 250,000 tonnes a year. Much of this is imported plastic packaging.

Many New Zealanders are very or extremely worried about the impact of plastic waste. We cannot continue ignoring our role in the global plastic pollution crisis while dumping plastic in homegrown landfills or in developing countries.

Read more: We organised a conference for 570 people without using plastic. Here’s how it went

In the scramble to find alternatives, waste-to-energy (WtE) incineration has become a hot topic, particularly as foreign investors look to establish WtE incinerators on the West Coast and [other centres]in New Zealand. Some local government representatives have endorsed WtE proposals, or raised WtE as an election issue.

Less plastic good for climate

Like landfills, WtE incinerators symbolise the linear “take-make-waste” economy, which destroys valuable resources and perpetuates waste generation.

Globally, countries are moving to circular approaches instead, which follow the “zero waste hierarchy”. This prioritises waste prevention, reduction, reuse, recycling and composting and considers WtE unacceptable.

Some New Zealanders say Nordic countries have proven that incineration is the environmental silver bullet to our waste woes. But a recent study found these countries will not meet EU circular economy goals unless they replace WtE incineration with policies that reduce waste generation. Such policies include packaging taxes, recycling and recovery rate targets, landfill bans on biodegradable waste, deposit return schemes and extended producer responsibility.

Rejecting linear approaches is also good for the climate. Actions at the top of the waste hierarchy stop more greenhouse gases than those at the bottom.

In contrast, WtE incinerators can produce 1.2 tonnes of carbon dioxide per tonne of municipal solid waste burnt. New Zealand’s zero carbon act means we have a responsibility to ensure we do not increase our greenhouse gas emissions by investing in WtE incineration.

Incinerators also cannot magic away toxins in plastic waste. Even the most high-tech WtE incinerators [[release dioxins and other pollutants into the air]. Meanwhile, toxin-laden fly ash and slag are dumped in landfills to eventually leach into the environment and contaminate food systems.

Shifting responsibility for plastic waste

To address plastic pollution, it is easy to see how prevention and reduction work better than “getting rid of” plastic once produced. Many WtE proponents argue that incineration technology can be a temporary solution for the plastic waste we have already created.

But incinerators are not short-term fixes. They are expensive to build and maintain. Large-scale incinerators demand about 100,000 tonnes of municipal solid waste a year, encouraging increasing production of waste. Investors guarantee returns on their investment by locking councils into decades-long contracts.

The only real solution to our plastics problem is through regulation that moves New Zealand towards a circular economy. We can start by making the linear economy expensive by increasing landfill levies above the current $NZ10/tonne and expanding it to all landfills. We must also invest in better waste collection, sorting and recycling systems, including a national network of resource recovery centres.

Instead of burning or burying plastic that cannot be reused, recycled or composted, we can prevent or reduce it through targeted phase-outs. The government is proposing to regulate single-use plastic packaging, beverage packaging, electronic waste and farm plastics through mandatory product stewardship schemes. This would make manufacturers responsible for the waste they produce and provide incentives for less wasteful and toxic product design and delivery systems (e.g. refill stations).

All of these circular solutions will provide far more jobs than WtE incineration.

Without a swift, brave shift to a circular economy, New Zealand will remain one of the world’s most wasteful nations. Circular economies are developing globally and WtE incineration will only set us back by 30 years.

Hannah Blumhardt, the coordinator of the NZ Product Stewardship Council, has contributed to this article.

It has been called “the robbery of the century”. Martin Shields and Nicholas Diable, two British investment bankers, are on trial in Germany for helping structure a massive tax evasion scheme, known as cum-ex trading, that has siphoned up to €55 billion (about US$60 billion or A$90 billion) from European public funds.

Let’s put that in perspective.

The world’s most successful diamond thieves, the “Pink Panther” group, are suspected of heisting jewels worth €334 million (about A$544 million). The largest bank job in history, a “cash withdrawal” from the Central Bank of Iraq by Saddam Hussein, is estimated to have been worth US$1 billion (about A$1.45 billion). The biggest ponzi scheme in history, by Bernie Madoff, defrauded investors of about US$20 billion.

So a €55 billion fraud is a very big deal.

Yet there’s a good chance you haven’t heard much about it. One reason is that, unlike video footage of someone ram-raiding a liquor store, financial fraud doesn’t make good television.

This specific alleged crime involves “cum-ex fraud”. If you have no idea what this is, you are not alone. It involves bafflingly complex transactions and jargon. Even the most basic cum-ex deal involves at least 12 transactions.

It’s one of those ironies that complexity not only helped hide this alleged crime in the first place, but also helps keep it out of the public eye now.

Let’s try to remedy this by getting to grips with what cum-ex trading is all about.

What is cum-ex trading?

The term cum-ex comes from the Latin – cum meaning “with” and ex meaning “without”. In this case, “with” and “without” refers to stocks with and without dividends.

The cum-ex trading in question took advantage of a loophole in German tax law and involved rapidly exchanging stock “with” and then “without” dividends between three parties. At least two of these parties then claimed tax rebates on taxes only paid once.

There are three key things at play here.

First is when companies pay dividends to shareholders. This usually happens quarterly when companies audit exactly who owns their stock, known as the Record Date.

Second, dividends are taxed differently for individuals and corporations (such as investment companies). In Germany, individuals pay 25% capital gains tax on all dividends. For corporations, however, their dividend income is combined with all other income. Then, once a year, they pay 15% corporation tax on their profit.

Third, capital gains tax is automatically deducted from all dividend payments. Institutional investors can therefore legitimately reclaim the capital gains tax that has already been deducted.

How cum-ex trading works

Shields and Diable were allegedly just part of a sprawling web of bankers, brokers, investors, asset managers, lawyers and consultants who, together, rapidly transferred company shares either side of the dividend Record Date. This made it almost impossible for Germany’s tax office to know exactly who did (or didn’t) own company shares at what time.

Simplified, cum-ex trading works something like this:

Party One, typically an asset manager who owns valuable company shares, “lends” its stock to Party Two, a bank. Under the agreement, the title and ownership of the stock is temporarily transferred to the borrower in return for a fee. Such practices are not only legal but a common part of “short selling”, the practice featured in the 2015 film The Big Short. Essentially, it is where an investor borrows a stock (for a fee), sells it, then buys it back later at a lower price to return it to the original – on the expectation the stock’s value will fall and a profit made.

Read more: Explainer: what is short selling?

Party Two then sells the shares with-dividend to Party Three fractionally before the Record Date. However, the shares are delivered without-dividend just after.

Timing, speed and complexity are key. Like a magic trick, the shares “disappear” fractionally before the Record Date and “reappear” with a new owner just after. The aim is to obscure exactly who – Party One, Two or Three – owns the stock on the Record Date. As a result, two parties can simultaneously claim ownership of the one stock.

Up until 2011, a loophole in the German tax code allowed both Party One (the owner of the original stock who had received the dividend and paid tax on it) and Party Three (the holder of the stock just after the Record Date) to claim a tax reimbursement. All colluding parties would then split the gains.

What of the trial?

Shields and Diable stand accused of 34 instances of “aggravated tax evasion” that cost German taxpayers up to €450 million (A$730 million) between 2006 and 2011. Indicating the complexity of the case, the charge sheet runs to 651 pages.

Shields, who is cooperating with prosecutors, has said in court that cum-ex trades took place on an “industrial scale” and involved a vast network of banks, companies, brokers, lawyers and financial advisers. Now a judge has to decide whether these cum-ex trades merely exploited a loophole or violated the law at the time.

In a sign of how twitchy high-profile banks are getting, the courtroom’s gallery has been packed with their legal representatives. They have good reason to be. The Cum-ex Files investigation by European media groups has evidence the practice continued in Germany until 2016, and also occurred in Switzerland, Austria, Finland, Spain, and France. It may even have spread as far as Australia.

Cum-ex deals illustrate perfectly how easily complexity is used as a tool in finance to misdirect, obfuscate and perplex. The complexity also plays a key role in clouding public understanding of these alleged crimes. It’s easier for the media to focus public attention on simpler crimes with clearly identifiable victims.

All this is why Shields and Diable, despite the staggering sums of money involved, face maximum prison sentences of 10 years, while “blue-collar” robberies often incur far heavier sentences and attract much more sensational media attention.

Two judges in the High Court of Australia this morning referred Cardinal George Pell’s application for special leave to appeal his convictions to a full bench of the High Court.

While not a full grant of special leave, this is favourable to Pell, as dismissing the application would have finalised the case and his convictions.

When the High Court hears the case in coming months, it can reject or grant the special leave application. If granted, it can then allow or dismiss the appeal.

The case is exceptionally complex and the final outcome is difficult to predict. Allowing leave to appeal does not guarantee the appeal will succeed. Here is what might happen next.

What happened with the convictions?

In December 2018, a jury unanimously found Pell guilty of five sexual offences against two 13-year-old choirboys, committed when he was Archbishop of Melbourne from 1996-97. The offences were one count of sexual penetration of a child aged under 16 through forced oral sex, and four counts of an indecent act with or in the presence of a child aged under 16. He was sentenced to six years’ prison with a non-parole period of three years and eight months.

What happened with the failed appeal?

In August 2019, Victoria’s Court of Appeal dismissed Pell’s appeal against these convictions by a 2:1 majority decision. The background is summarised elsewhere. The key issue was whether the verdicts were “unreasonable” or could not be supported on the evidence. The question was whether, given the evidence, it was “open to the jury” to be satisfied beyond reasonable doubt the accused was guilty.

It is not enough to overturn a guilty verdict if the court merely finds a jury “might have” had a reasonable doubt. Rather, the court must find that, on its assessment of the evidence, it was not open to the jury to have been satisfied of guilt beyond reasonable doubt. So the evidence must have “obliged” the jury to reach a not guilty verdict. Because of the jury’s role as tribunal of fact, setting aside a guilty verdict is “a serious step” (see the case M v R).

The majority judges, Chief Justice Anne Ferguson and Justice Chris Maxwell, concluded the guilty verdicts were open to the jury. They did not have a doubt about the complainant’s truthfulness or the cardinal’s guilt. They made crucial findings after careful and cogent reasoning, considering each aspect of the defence case.

Read more: George Pell has lost his appeal. What did the court decide and what happens now?

First, the complainant was credible and reliable. His account was consistent and detailed. His recalled detail of the sacristy layout enhanced his credibility and independently confirmed his account, as it was not normally used by the archbishop.

Second, the majority judges evaluated each defence claim individually and collectively. They rejected the claim that the “opportunity” testimony (defence witnesses’ statements about where they, Pell and the choirboys would likely have been at relevant times) made the guilty verdicts unreasonable. Essentially, this testimony was not deemed sufficiently strong to make the verdict unreasonable or “not open”. Its effect was “of uncertainty and imprecision”. There was evidence showing “a realistic opportunity” for the offending.

The dissenting judge, Justice Mark Weinberg, gave extensive reasons. On his interpretation of the “opportunity” testimony – including statements by two witnesses about customarily being with Pell at relevant times – there was a “reasonable possibility” of an effective alibi for the first four offences. Weinberg himself had “a genuine doubt” about Pell’s guilt, thought there was a “significant possibility” the offences had not been committed, and inferred the jury ought to have had this doubt.

The application for special leave to appeal to the High Court

The High Court does not lightly give leave to appeal. It can only grant leave if:

• the proceedings involve a question of legal principle; or

• the interests of the administration of justice (generally, or here) require consideration of the earlier judgment.

Pell’s team made two arguments, relying on the dissenting judgment. First, they argued the majority’s approach to the “open to the jury” test was wrong, effectively requiring the applicant to exclude any possibility of the offending to have occurred, which reversed the onus and standard of proof. They also argued the majority’s belief in the complainant was not enough to overcome doubts raised by the opportunity testimony, and the alibi evidence had not been eliminated.

Second, they argued there was sufficient doubt about whether the offending was possible. This, they said, made the verdicts unreasonable, given the complainant’s account required them to be alone in the sacristy for five to six minutes. They argued that after mass and five to six minutes of “private prayer time” there was a “hive of activity” near the sacristy, and the majority incorrectly found it was reasonably open to the jury to find the offending happened during this period.

The director of public prosecutions argued there simply was no such error by the majority in applying the test, and the verdicts were not unreasonable.

In large part, the special leave application turned on the different approaches to whether the “opportunity evidence” was sufficiently strong to create enough doubt that it was “not open to the jury” to find Pell guilty beyond reasonable doubt.

What did the High Court say?

The transcript had not been released at the time of writing, but the two judges referred the application for special leave to hearing by a full bench (five or seven members) for argument as on an appeal. There, the full High Court can reject or grant the special leave application.

On one view, this is surprising. Applications arguing an unreasonable verdict in child sexual offence cases are typically dismissed (for example, O’Brien; in contrast GAX).

The High Court generally does not grant leave simply due to an alternative interpretation of the facts. The majority judgment in the appeal accurately stated the test. It applied the test by carefully analysing all the arguments and testimony individually and collectively, applying cogent reasoning in independently assessing the sufficiency and quality of the evidence. It weighed the evidence and expressed an independent conclusion about whether on all the evidence it was open to the jury to be satisfied of guilt beyond reasonable doubt.

On the other hand, the two High Court judges may reasonably feel there are important issues of legal principle and justice to consider, and that such a significant case warrants full consideration at all levels by the entire court.

What happens now?

The full hearing of the special leave application will occur in 2020. If leave is then granted, the appeal will proceed. If the appeal succeeds, the court can grant a new trial, or reverse or modify the prior judgment.

However, if special leave is refused at the full hearing, or granted but the appeal fails, the convictions stand and no further appeal is possible.

Yesterday, New South Wales and Queensland issued fire warnings classified as either “catastrophic”, “severe” or “extreme” – and these conditions will remain in the coming days.

Areas under threat include the greater Sydney area, northern New South Wales, the Northern Goldfields, and the Central Highlands. The declared state of emergency means human life is at great risk.

Those at risk should evacuate ahead of time, as mobile phone services may not be reliable when needed the most.

Service outages

People in dangerous bushfire situations often have the added burden of service outages. This can happen following fire damage to infrastructure (such as signal towers) that connects base stations that relay communications within the network. A break in this connection means no signal, or weak signal, for those on the ground.

Generally, radio waves used for mobile communication behave differently as they travel, based on various factors that affect signal strength. One factor is land geography, such as the height of hills. The signal may not be able to penetrate sand hills. Gum trees may also reflect, obstruct and absorb radio signals.

Read more: Where to take refuge in your home during a bushfire

The scenarios described above can be made worse by fire environments, based on the frequencies used. Flames can produce “plasma”, which reacts with the surrounding magnetic field, and this degrades signal strength.

Rural fire service operations may use frequencies in the 400-450MHz range to communicate, but these signals are weakened during fire, in which case they may use frequencies in the 100-180MHz range. At this wavelength, signal strength doesn’t degrade as badly and can sustain better communication.

Being far away from a mobile phone tower, often in rural areas, also results in degraded communication. Rural areas don’t receive as much coverage because installing cell towers in these areas is not particularly profitable, and towers are built based on revenue estimates. There is little incentive to build networks with additional capacity in rural areas.

Get out while you can

In bushfire situations, it’s crucial to leave affected areas early to avoid becoming stuck in mobile black spots. These are regional and remote areas that have been identified as not having mobile phone coverage.

Some mobile black spots where fire danger warnings have been issued include Mount Seaview and Yarras, not far from the Oxley Highway in NSW. The status of the fires there was reported “out of control” on Tuesday morning.

Read more: What has Australia learned from Black Saturday?

Optus is planning to roll out macrocells at these locations to expand coverage between the end of this year and the middle of next year. These are base stations that cover a wide area and are typically deployed in rural regions or along highways.

Until the macrocells are deployed, people living in mobile black spots, or who may be forced to pass through these areas due to fire, continue to be at risk. When passing through a fire-affected black spot, you are virtually unreachable.

Also, although the mobile black spot program will help to increase 4G coverage in rural areas, most rural areas, including many at high risk of bushfires, rely largely on 3G. When people need extra data capacity during emergencies, the network is incapable of handling the increased traffic load, as every device is trying to connect and download data at the minimum 3G capacity of 550Kbps.

Network overload

The network gets congested at times of catastrophe due to the high volume of mobile phone traffic experienced, which exceeds the available network capacity. The mobile network in Billy’s Creek in NSW, and the areas connected to it, experienced an outage yesterday.

Telstra’s services have also been affected. As of Monday, people in Billy’s Creek, Yarras and Nimbin (among other locations) were unable to send or receive messages, make calls or access the internet, and may not have been up to date with the latest fire information, unless through radio or television.

During bushfires last year, for every three calls attempted under Telstra’s network, one was eventually answered. Everyone trying to call at once is referred to as a “mass call event”. This creates “congestive collapse” in parts of the internet-based network, blocking new connections from being made.

During congestion, the performance of the network decreases because the internet packets that carry the calls or messages are dropped, or delayed, before they reach their destination. One solution is for operators to have signal boosters installed for the affected part of the network.

There’s an app for that, if you have good connection

In the same way, the “Fires Near Me Australia” web application is likely to suffer from internet packet deliveries being delayed.

The app may be overwhelmed if too many people try to access it at once, and may crash. In such scenarios, people should reboot their phones and keep trying to connect.

Some people have made complaints of not being able to download the app, and others of the app crashing, because their phone’s model was not new enough to support it.

If the fires spread to densely populated areas, available 4G capacities may be exhausted by the sheer volume of the traffic. And congestion is made worse by more incoming traffic from across the country, from concerned family and friends.

Preventative measures may no longer be an option for many. But in the future, people in fire-prone areas may benefit from buying a personal 4G or 3G mobile signal booster ahead of time.

In the past week, news has spread of a Florida judge’s decision to grant a warrant allowing police to search one of the world’s largest online DNA databases, for leads in a criminal case.

The warrant reportedly approved the search of open source genealogy database GEDMatch. An estimated 1.3 million users have uploaded their DNA data onto it, without knowing it would be accessible by law enforcement.

A decision of this kind raises concern and sets a new precedent for law enforcement’s access to online DNA databases. Should Australian users of online genealogy services be concerned?

Why is this a big deal?

GEDmatch lets users upload their raw genetic data, obtained from companies such as Ancestry or 23andMe, to be matched with relatives who have also uploaded their data.

Law enforcement’s capacity to use GEDmatch to solve crimes became prominent in April last year, when it was used to solve the Golden State Killer case. After this raised significant public concern around privacy issues, GEDmatch updated its terms and conditions in May.

Under the new terms, law enforcement agencies can only access user data in cases where users have consented to use by law enforcement, with only 185,000 people opting in so far.

Read more: No, Mr Dutton, DNA testing ISIS brides won’t tell you who’s an Australian citizen

The terms of the warrant granted in Florida, however, allowed access to the full database – including individuals who had not opted in. This directly overrides explicit user consent.

GEDmatch reportedly complied with the search warrant within 24 hours of it being granted.

Aussies are also at risk

GEDMatch is small fry compared with ancestry database giants Ancestry (more than 15 million individuals) and 23andMe (more than 10 million individuals), both of which have DNA data belonging to Australians.

Australians who wish to have ancestry DNA testing have to use US-based online companies. Thus, many Australians have data in databases such as Ancestry, 23andMe and GEDMatch. The granting of a warrant to search these databases by US courts means those searches could include Australian individuals’ data.

Ancestry and 23andMe both have policies saying they don’t provide access to their databases without valid court-mandated processes.

Each company produces a transparency report (see here and here) which includes all requests for customer data that have been received and complied with. Currently, that number is low. But it remains to be seen how each would respond to a court-ordered search warrant.

Furthermore, while Australia currently doesn’t have it’s own genetic database (and no plans have been announced), the federal government’s commitment of A$500 million to the Genomics Health Futures Mission indicates a growing interest in the power of genomics for health.

If Australia wants to remain internationally competitive, a national genetics project is a natural next step.

We need DNA privacy legislation

In Australia, courts can approve warrants that intrude into private information, and entities can only protect data to the extent that it’s protected by law.

Thus, the privacy policies of companies and organisations that hold genetic data (and other types of private data) usually include a statement saying the data will not be shared without consent “except as required by law”.

The Australian Information Commissioner can also allow breaches of privacy in the public interest.

Read more: What does DNA sound like? Using music to unlock the secrets of genetic code

It has been more than two decades since Senator Natasha Stott-Despoja proposed the Genetic Privacy and Non-Discrimination Bill.

Although Australia has a patchwork of laws that protect citizens’ genetic data to an extent, we still have no specific genetic data protection legislation. A broader legal framework dealing directly with the protection of genetic information is now required.

Australian politicians have previously shown willingness to use genetic information for government purposes. As genetic advances strengthen the promise of personalised medicine, Australian academics continue to call for urgent genetic data protection legislation. This is important to ensure public trust in genetic privacy is maintained.

Ongoing concerns around genetic discrimination, and other ethical concerns, warrant an urgent policy response regarding the protection of genetic data.

What are other countries doing?

Globally, several DNA databases have amassed genetic datasets of more than 1 million individuals, including for research purposes and healthcare improvement.

Few databases outside the US have yet to reach the numbers needed to be useful for identification purposes.

However, many countries, particularly in Europe, have started establishing government-funded national databases of gene donor data, including Sweden and Estonia.

The Estonian Biobank is one of the most advanced national DNA databases. It has more than 200,000 donor samples.

With a population of around 1.3 million people, the biobank represents around 15% of the entire country’s population. And Estonian legislation currently prohibits the use of donor samples for law enforcement.

Read more: From the crime scene to the courtroom: the journey of a DNA sample

In contrast, the UK Biobank, doesn’t have specific legislation controlling its operation. It only allows law enforcement agencies access if forced to do so by the courts, leaving open the possibility of access under a court-ordered warrant.

The biobank currently has samples from around 500,000 individuals, but plans to collect at least 1 million more in future.

In Australia, accessing DNA testing is now easier than ever. But those accessing it through US-based companies, or uploading their data to US-based databases, should be aware of the potential uses of their genetic information.

And as we moves into an era of genomic medicine, urgent policy attention is required from the Australian government to ensure public trust in genomics is maintained.

Following the Royal Commission into Institutional Responses to Child Sexual Abuse, we are witnessing a wave of legal reforms across Australia aimed at helping survivors seek justice.

Most visibly, there is the National Redress Scheme, which provides victims access to counselling, a response from the institution where they were abused and payment of up to $150,000.

But for those who slip through the cracks of the scheme, as well as future victims, pursuing justice through civil litigation is still hugely important.

As traumatising as legal action can be, suing is not just a means to access compensation. It can also provide formal legal recognition of the abuse, and is a powerful way to hold the institution directly accountable.

Read more: In landmark ruling, Archbishop Philip Wilson found guilty of covering up child sex abuse

Legal hurdles for victims suing institutions

Historically, there have been several legal roadblocks for victims trying to sue the organisations where they were abused.

• Statutes of limitations can prevent lawsuits if it takes many years for victims to acknowledge the abuse and take action.

• It can also be hard to identify a legal entity to sue, given that many religious institutions are unincorporated. This hurdle is commonly known as the “Ellis defence”, after the case brought by an altar boy against the Catholic Church that failed for this reason.

• For an organisation to be held responsible for abuse, victims must establish a close connection between the abuser and institution. Institutional responsibility for employees’ wrongful actions – known as “vicarious liability” – typically covers carelessness in the workplace but doesn’t usually extend to serious criminal acts like assault. (A separate issue: historically recognised duties owed by schools and hospitals are also not owed by other organisations like churches.)

Since the royal commission identified these barriers in a 2014 report on redress and civil litigation, states and territories have begun introducing new laws to change their statutes of limitations and bypass the Ellis defence.

However, addressing the legal responsibility of institutions for the actions of individual perpetrators has proven more complex.

The confusion over liability in Victoria

Some states are moving forward with legal reforms in this area. NSW, for instance, overhauled its laws last year to extend vicarious liability to include non-employees like volunteers or religious officers who take advantage of their positions to carry out child abuse.

Tasmania has now introduced a bill taking a similar approach. Several other jurisdictions – ACT, WA and SA – have yet to take any action on this issue. They are still responding to the royal commission’s recommendations, so further legislation may be forthcoming.

Victoria, meanwhile, has taken a different approach that is leaving some victims behind. (It’s a model Queensland also now appears to be following.)

This is especially disappointing given Victoria actually led the way with legal reforms to help victims of child sex abuse, based on a 700-page report by a parliamentary inquiry that was set up before the royal commission.

The Victorian report looked in detail at the legal hurdles that victims face, but its recommendations showed a misunderstanding of the law when it comes to the liability of institutions where abuse occurs.

Specifically, it misunderstood how vicarious liability works.

What is vicarious liability?

Vicarious liability is a form of strict liability under which an employer can be held responsible for the actions of employees regardless of fault. This is so even when it has taken all reasonable steps to prevent the misconduct.

For example, a bus company may be liable for harm to passengers caused by a careless bus driver, even when it did everything it could to encourage safe driving.

However, previous court decisions have suggested it wasn’t possible for employers like schools to be held vicariously liable for the abuse of children by teachers. The reason: such liability doesn’t usually extend to serious criminal acts because they weren’t committed within the “course of employment”.

Victoria’s child sex abuse report recommended fixing this legal complexity by importing a model from discrimination law.

In this model, an organisation is presumed to be responsible for the acts of its employees but can escape liability by showing it took reasonable care to avoid the wrongful conduct.

Read more: The Catholic Church is investigating George Pell’s case. What does that mean?

Eager to remove the barriers faced by child sex abuse victims, the Victorian government changed its laws in 2017 to import the new model. But it ignored two key developments that happened while the new law was being debated in parliament.

First, the royal commission provided a more thorough analysis of the laws and recommended imposing strict liability on specific kinds of institutions responsible for the care, supervision or control of children.

Second, in 2016, a High Court case involving child sexual abuse at a boarding school, Prince Alfred College v ADC, signalled an entirely new approach courts will take with regard to vicarious liability in such cases.

The High Court stated that if an employer puts an employee in a position of trust, power and the ability to achieve intimacy with a victim, the organisation will be held liable if the employee takes advantage of the situation to abuse a child.

The High Court’s new approach also has its gaps. Victims who were abused by a contractor rather than an employee might struggle to establish vicarious liability. We’re also yet to see whether courts consider clergy as employees for this purpose.

More reforms are needed

Victorian MPs saw the state’s new laws as “balancing the interests” of organisations and victims of abuse. They also believed the laws avoided placing “undue burden” on organisations by allowing them to escape liability if they have taken reasonable care.

But this ignored the courts’ new approach to vicarious liability and the fact that strict liability may still apply to organisations that took reasonable care.

Ultimately, the Victorian government has done a disservice to survivors of child abuse and made the legal situation murkier rather than clearer for organisations and victims alike.

The bottom line is that Victoria – and other states and territories – still need further reform in this area if they really want to help victims of institutional child abuse achieve justice in the courts.

It’s 25 years since the fourth edition of the Diagnostic and Statistical Manual (DSM-IV) was published. The manual is the clinical “bible” that defines the criteria for the diagnosis of psychiatric and neurodevelopmental conditions, and was a landmark document for autism spectrum disorder.

The first mention of autism came in the third edition of the DSM in 1980, with the introduction of the diagnostic category of “infantile autism”. This label was generally only applied to children with substantial language impairment and intellectual disabilities.

In 1994, the DSM-IV recognised people could also show the core behaviours of autism without having significant language impairment or any intellectual disability. This change in how we described autism contributed to a surge in diagnoses.

Read more: Do more children have autism now than before?

There was also a surge in autism research, from around 96 studies in 1994, to 207 in 2000, and then 2,789 in 2018.

So, 25 years on, what have we learnt about autism?

The autism concept

In the 1990s, we viewed autism as one condition, with all children showing similar, severe difficulties with social and communication skills.

We now know the reality is very different.

In its most literal sense, autism is diagnosed when a person displays a set of behaviours typified by difficulties in social interaction and communication, as well as having more restricted interests and repetitive behaviours than we typically expect.

Read more: Why do some people with autism have restricted interests and repetitive movements?

The severity of the behaviours that characterise autism vary considerably between people. Social interaction and communication difficulties, for example, can range from having no verbal language to highly fluent language.

The frequency and intensity of autism behaviours – such as repetitive play with objects and repeated body movements like rocking and hand flapping – vary between mild and severe.

And intellectual abilities can range from significant disability to a very high IQ.

This variation is the so-called “autism spectrum”, which has also led to the worldwide movement of “neurodiversity”. This views neurological conditions such as autism as part of the natural spectrum of human diversity, and posits that this diversity should be respected rather than pathologised.

Neurodiversity challenges the medical model of autism as a disorder, instead viewing autism as an inseparable aspect of identity.

Autism is diagnosed by a team of clinicians, through a consistent and rigorous diagnostic process. While the dividing line between “typical” and “atypical” can be blurry, a diagnosis is made when the core behaviours of autism have a functional impact on an individual’s daily life.

It’s now clear that autism is not one condition in the sense that there is a common cause shared by all people on the autism spectrum.

Instead, autism is best thought of as an umbrella term which describes a range of different people, all with relatively similar behaviours, which may or may not be caused by the same biological factors.

Critically, autism is not just a childhood condition. While the behavioural characteristics of autism first emerge during childhood, they almost always persist into adolescence and adulthood, but often present in a different form.

Social difficulties in childhood might be shown through a preference to play alone, for example, while in adulthood this may be reflected by difficulty in maintaining social relationships.

Read more: We need to stop perpetuating the myth that children grow out of autism

The dramatic refinement of our understanding of autism from a severe childhood condition, to a cluster of complex and variable conditions that endure into adulthood, is a great achievement of scientific research and has driven all other research and policy advances.

Causes

In 1994, there was already a good understanding that autism originated from genetic differences.

Advances in genetic research in the late 1990s and 2000s – first by sequencing the human genome, then the dramatic reduction in the cost of this sequencing – led scientists to believe they would soon find the single gene that causes the brain to develop differently.

But after several decades of intensive research, the picture turned out to be far more complex.

There is now consensus that there is no one genetic difference shared by all individuals with autism. And rarely does one person possess a single genetic factor that leads the brain to develop differently.

There is also evidence to suggest other biological factors may play a role in the development of autism, including inflammation and hormonal factors. But the evidence for these factors remains preliminary.

Read more: What causes autism? What we know, don’t know and suspect

We now know a range of conditions, including Fragile X syndrome and tuberous sclerosis, have very clear genetic or chromosomal differences that can lead to autistic behaviours. In total, these conditions account for around 10% of all people on the autism spectrum.

Genetic factors are still very likely to underpin autism in the remaining majority of people. But the genetic differences are likely more complex, and require advances in statistical techniques to better understand why the brain develops differently for some children.

Therapies and treatments

In the 1990s, behavioural interventions for autism were dominated by applied behaviour analysis (ABA), an approach to therapy that helps children learn new skills.

While ABA remains prominent throughout the world, other therapeutic models have emerged, such as those based on developmental principles, those that target communication and those that use a combination of approaches.

While these therapies help the development of some children with autism, no one therapy model will be effective for all. The great advance of the last 25 years has been to provide families with alternate options if their original choice of therapy isn’t as beneficial as they hoped.

Read more: A guide for how to choose therapy for a child with autism

But pharmacological (drug) treatments have not seen as much progress. Despite substantial research investment, there remains no medication with good evidence for reducing the disability associated with the core social and communication difficulties of autism.

Pharmacological intervention in autism is primarily used to assist with other challenges that can be associated with autism such as anxiety, attention problems, epilepsy and sleeping difficulties.

Where to next?

Despite progress over the past 25 years, health and disability challenges remain pervasive for people on the autism spectrum, and our policy responses continue to be fragmented across health, disability and education systems.

Given the ever-marching advance of science, it’s impossible to predict the next 25 years of research. A key challenge for scientists is how we use the knowledge we create to lead to clear and tangible benefits for humanity.

This will likely require meaningful partnerships with autistic people and their families to better understand their priorities for their lives. We need to learn how the knowledge we’ve obtained, and that still to come, can best support each person to discover their own strengths and what they want for their lives.

For more than 3.5 billion years, living organisms have thrived, multiplied and diversified to occupy every ecosystem on Earth. The flip side to this explosion of new species is that species extinctions have also always been part of the evolutionary life cycle.

But these two processes are not always in step. When the loss of species rapidly outpaces the formation of new species, this balance can be tipped enough to elicit what are known as “mass extinction” events.

Read more: Climate change is killing off Earth’s little creatures

A mass extinction is usually defined as a loss of about three quarters of all species in existence across the entire Earth over a “short” geological period of time. Given the vast amount of time since life first evolved on the planet, “short” is defined as anything less than 2.8 million years.

Since at least the Cambrian period that began around 540 million years ago when the diversity of life first exploded into a vast array of forms, only five extinction events have definitively met these mass-extinction criteria.

These so-called “Big Five” have become part of the scientific benchmark to determine whether human beings have today created the conditions for a sixth mass extinction.

The Big Five

These five mass extinctions have happened on average every 100 million years or so since the Cambrian, although there is no detectable pattern in their particular timing. Each event itself lasted between 50 thousand and 2.76 million years. The first mass extinction happened at the end of the Ordovician period about 443 million years ago and wiped out over 85% of all species.

The Ordovician event seems to have been the result of two climate phenomena. First, a planetary-scale period of glaciation (a global-scale “ice age”), then a rapid warming period.

The second mass extinction occurred during the Late Devonian period around 374 million years ago. This affected around 75% of all species, most of which were bottom-dwelling invertebrates in tropical seas at that time.

This period in Earth’s past was characterised by high variation in sea levels, and rapidly alternating conditions of global cooling and warming. It was also the time when plants were starting to take over dry land, and there was a drop in global CO₂ concentration; all this was accompanied by soil transformation and periods of low oxygen.

The third and most devastating of the Big Five occurred at the end of the Permian period around 250 million years ago. This wiped out more than 95% of all species in existence at the time.

Some of the suggested causes include an asteroid impact that filled the air with pulverised particle, creating unfavourable climate conditions for many species. These could have blocked the sun and generated intense acid rains. Some other possible causes are still debated, such as massive volcanic activity in what is today Siberia, increasing ocean toxicity caused by an increase in atmospheric CO₂, or the spread of oxygen-poor water in the deep ocean.

Fifty million years after the great Permian extinction, about 80% of the world’s species again went extinct during the Triassic event. This was possibly caused by some colossal geological activity in what is today the Atlantic Ocean that would have elevated atmospheric CO₂ concentrations, increased global temperatures, and acidified oceans.

The last and probably most well-known of the mass-extinction events happened during the Cretaceous period, when an estimated 76% of all species went extinct, including the non-avian dinosaurs. The demise of the dinosaur super predators gave mammals a new opportunity to diversify and occupy new habitats, from which human beings eventually evolved.

The most likely cause of the Cretaceous mass extinction was an extraterrestrial impact in the Yucatán of modern-day Mexico, a massive volcanic eruption in the Deccan Province of modern-day west-central India, or both in combination.

Is today’s biodiversity crisis a sixth mass extinction?

The Earth is currently experiencing an extinction crisis largely due to the exploitation of the planet by people. But whether this constitutes a sixth mass extinction depends on whether today’s extinction rate is greater than the “normal” or “background” rate that occurs between mass extinctions.

This background rate indicates how fast species would be expected to disappear in absence of human endeavour, and it’s mostly measured using the fossil record to count how many species died out between mass extinction events.

The most accepted background rate estimated from the fossil record gives an average lifespan of about one million years for a species, or one species extinction per million species-years. But this estimated rate is highly uncertain, ranging between 0.1 and 2.0 extinctions per million species-years. Whether we are now indeed in a sixth mass extinction depends to some extent on the true value of this rate. Otherwise, it’s difficult to compare Earth’s situation today with the past.

In contrast to the the Big Five, today’s species losses are driven by a mix of direct and indirect human activities, such as the destruction and fragmentation of habitats, direct exploitation like fishing and hunting, chemical pollution, invasive species, and human-caused global warming.

If we use the same approach to estimate today’s extinctions per million species-years, we come up with a rate that is between ten and 10,000 times higher than the background rate.

Even considering a conservative background rate of two extinctions per million species-years, the number of species that have gone extinct in the last century would have otherwise taken between 800 and 10,000 years to disappear if they were merely succumbing to the expected extinctions that happen at random. This alone supports the notion that the Earth is at least experiencing many more extinctions than expected from the background rate.

It would likely take several millions of years of normal evolutionary diversification to “restore” the Earth’s species to what they were prior to human beings rapidly changing the planet. Among land vertebrates (species with an internal skeleton), 322 species have been recorded going extinct since the year 1500, or about 1.2 species going extinction every two years.

If this doesn’t sound like much, it’s important to remember extinction is always preceded by a loss in population abundance and shrinking distributions. Based on the number of decreasing vertebrate species listed in the International Union for Conservation of Nature’s Red List of Threatened Species, 32% of all known species across all ecosystems and groups are decreasing in abundance and range. In fact, the Earth has lost about 60% of all vertebrate individuals since 1970.

Australia has one of the worst recent extinction records of any continent, with more than 100 species of vertebrates going extinct since the first people arrived over 50 thousand years ago. And more than 300 animal and 1,000 plant species are now considered threatened with imminent extinction.

Read more: An end to endings: how to stop more Australian species going extinct

Although biologists are still debating how much the current extinction rate exceeds the background rate, even the most conservative estimates reveal an exceptionally rapid loss of biodiversity typical of a mass extinction event.

In fact, some studies show that the interacting conditions experienced today, such as accelerated climate change, changing atmospheric composition caused by human industry, and abnormal ecological stresses arising from human consumption of resources, define a perfect storm for extinctions. All these conditions together indicate that a sixth mass extinction is already well under way.

Once upon a time when something was simple to do we said: “It’s as easy as riding a bike.” But switching from driving a car to riding a bike as one’s main means of transport is anything but easy.

The well-documented obstacles holding people back from cycling include a lack of proper bike lanes, secure parking arrangements, end-of-trip facilities and bike-friendly public transport, as well as lack of convenient storage space.

Read more: The problem isn’t dockless share bikes. It’s the lack of bike parking

Despite these obstacles, people continue to try to make cycling a central part of their lives, with varying degrees of success.

While we know broadly what the impediments are, we don’t know how individuals confront them over time. We tend to approach this issue as an “all or nothing” affair – either people cycle or they don’t. Research is often framed in terms of cyclists and non-cyclists.

But, for most people, our research tells us it is a gradual process of transformation, with setbacks as well as small victories. The hesitant maybe-cyclist of today is potentially the fully committed cyclist of tomorrow. Unfortunately, the reverse is also true.

We have taken a lead from research into smoking, which sees failed quit attempts not as failures but as necessary steps on the road to success. Part of our research is interested in the faltering starts people make in transitioning from motor vehicles to bikes. Our aim is to help identify new intervention points for cycling policy.

Cycling enthusiast Samuel Beckett aptly summed up this in Worstward Ho:

Try again. Fail again. Fail better.

Where the bike is kept is telling

Our question is: how can we fail better? Building on research with 58 cyclists in the Wollongong region, we recently shifted our emphasis to another local government area, the City of Sydney.

We focused on people who want to cycle but have mostly failed so far. We carried out in-depth qualitative interviews with 12 participants, following up each with a go-along, where participants guide us through their regular travel routes.

To date, all participants convey good intentions to incorporate cycling into their lives. All say they want to resume cycling, yet none have succeeded.

Their attempts were inhibited by commonplace issues: lost confidence in their abilities, less enjoyment of cycling because of congestion, and experiences of a car accident or a near miss.

Our research has found that where bicycles are stored is a reliable indicator of the changing value of the bicycle in an individual’s everyday life. One can pinpoint where someone is in the course of their starting-to-cycle journey by locating where their bike is kept.

When things are going well the bike is near the front door ready for immediate use. As things get difficult, the bike migrates from the front to the back of the house, to languish in a spare room or the shed, before finally being put out on the curb as hard rubbish (or for “freecycling”).

Read more: People take to their bikes when we make it safer and easier for them

Storage is a key obstacle

Contrary to interpretations of data indicating inner-city residents are the most likely to cycle, we have found participants who live in small, inner-city dwellings face daunting storage issues that all too often defeat them. They have told us about storing the bicycle inconveniently inside the house, wedged in dining rooms, hallways and bedrooms.

The search for a place to store the bike increased the inconvenience of using it for transport until finally the bike was locked away, kept only as a sign of ongoing intention and hope. This inconvenience defeats successive start attempts before they’re seriously able to be revived.

For example, Greg (37) confirms the “pain” of poor storage options discourages him from riding more regularly:

So it’s called the room under the stairs, according to the real estate agent. I don’t know how … And that’s partly the pain of taking it out. I would take it out more often, but every time I have to take it out I have to delicately wheel it here where you are. And sometimes scratch the wall, and then out through the door and gate … I would keep it outside, but my partner won’t let me because he thinks it will be stolen. I would ride more if it was just there, and I’d hop on and off.“

Urban design for convenience matters

The languishing bike prompts us to ask questions about the urban design of convenience. It’s a key element of any active transport policy that aims to promote cycling and walking.

Something as simple as lockable bike hangars on residential streets might liberate intentions into actions. Such facilities would be everyday visual reminders to cycle and an added symbol that cars are not the only way of occupying roads.

We invite others who have started this journey to share and celebrate their stories of failing better, particularly those in the City of Sydney, by participating in our research.

I start with a disclaimer: I am a UWA Publishing poet. I have published a book of poetry with them (as well as a novel), and have two books forthcoming with them in 2020 — The Weave, a collection of poetry co-written with Thurston Moore, and an edited and introduced volume, The Collected Poems of C.J. Brennan, the great, Sydney-dwelling, symbolist poet (1870-1932).

Now, with UWAP on the verge of being shut down, partly through what I and many others see as a misguided sense of what constitutes an interface between universities and the broader public, the fate of these books is unclear.

The University of Western Australia has proposed that “UWA Publishing operations, in their current form, come to an end” to be replaced by an open-source digital publishing model. The jobs of its employees and director Terri-ann White would likely be “surplus to requirements”. In a statement released late last week it said

Current publishing works already in train this year and next year are expected to continue, as will consultation on innovation that will assist UWA Publishing to adapt to the demands of modern publishing, with options to examine a mix of print, greater digitisation and open access publishing.

But even if contracted books are published, the closure of this publisher would be catastrophic for Australian poetry. It would be as if those books didn’t exist as something connected to a future vision of writing with purpose and community. It’s a way of killing a humanistic, inter-cultural conversation. It ignores the people who do so much to make these conversations happen.

Many voices

UWAP, especially since 2016, publishes many poetry books a year — a very unusual act of creative support and belief. Its dynamic list includes such essential voices as Ania Walwicz, Candy Royalle, Peter Rose, Quinn Eades, Kate Lilley, David McCooey, and so many other voices of the now, along with collected and selected “greats” like Francis Webb, Lesbia Harford, and Dorothy Hewett.

Yes, I speak here from the inside, as an author. Yet I also speak from the outside as a reader of poetry, and with the incredible feeling of loss I get as a reader, at this ill-thought out proposal.

UWAP publishes many “big name” writers and scholars, but also many marginalised voices and/or voices that might find it hard to publish through purely market-driven publishing houses. It is part of the country’s literary and scholarly collective conscience.

Poetry is an active ingredient of social justice not only in what it can say and talk about, but in the way that it places language under pressure, and questions how expression is used in general discourse, and why. Words of oppression are so easily accepted — poetry questions the uses and “deployment” of language.

UWAP, under Terri-ann White, is part of a clutch of poetry publishers in Australia — and there are not many — who make a commitment to poetry beyond the canonical, and with a strong sense of the need to enact this scrutiny of language. What is said in poetry is seen to matter, and I believe it does.

I will never forget speaking to the late Fay Zwicky in 2017, in her last weeks, about her forthcoming Collected Poems (UWAP, edited by Lucy Dougan and Tim Dolin) and her discussion of proofs and the book itself. A life’s work — one of the great bodies of poetry produced in Australia.

Zwicky had published volumes of poetry with other vital publishers in the Australia poetry community, University of Queensland Press and Giramondo. And then the collation of a life’s work — a big project that required so much attention and goodwill. It was clearly necessary, if not essential, to her.

One of the many titles on the UWAP list that had a remarkable effect on so many readers, and which I noted in the Australian Book Review’s 2018 Books of the Year feature, was a collation of Lisa Bellear’s poetry — Aboriginal Country. As I said then, “the emphatic, committed voice of this remarkable Goernpil woman, feminist, poet, photographer, and activist shines through.” Not to have had access to Bellear’s work is unimaginable now we have encountered it gathered in this way.

There is huge engagement in seeing such a work through to press. It was edited (by Jen Jewel Brown), supported and seen onto the shelves via UWAP. An act of belief and support, among many such acts in a given year; all necessary.

Vitally, UWAP’s poetry list effectively manages that seemingly complex interaction between local work and that from the rest of the country. It seems too often assumed that a WA publisher will necessarily only publish WA work. Now, don’t get me wrong, I am a total believer in local publishing, but there’s also a strong necessity for a publisher that brings many localities together, as Magabala Books in Broome does with Australian Aboriginal writing.

UWAP publishes poets (and writers in general) from all over the country, and brings in some overseas titles as well. Terri-ann White actively takes her lists to readers and publishers outside Australia, and is an energetic and steadfast voice in international publishing for her authors, and for Australian and world literature.

To close UWAP would be a damaging of shared difference, of making community and discussion out of diverse voices.

While I have had the good fortune over the years to publish with some of the major poetry houses around the English-speaking world, I am especially proud and excited when a book of mine is selected for the UWAP list.

Shutting down UWAP would sever many ties and disrupt many conversations just begun, or prevent other conversations, especially of conscience, ever taking place.

Myer is the in the clear, sort of, after Australia’s first judicial ruling on a securities class action.

It centred around allegations that Myer misled the market about its projected earnings.

The court found Myer had been misleading, but that because shareholders didn’t believe it, it didn’t harm them.

The ruling established important principles that will guide future judgments.

It isn’t enough for shareholders to show that there was a relevantly false or misleading statement or omission.

They need to also show it hurt them.

What Myer did

On September 11 2014, Myer’s chief executive Bernie Brookes indicated that he believed the net profit after tax for the 2015 financial year was likely to beat the previous year’s profit of A$98.5 million.

Five months later Brookes resigned, and on March 19 Myer cut the forecast to between $75 million and $80 million.

The class action alleged that Myer engaged in misleading conduct either because the initial September 11 2014 guidance was misleading or because – even if it was not misleading at the time – Myer allowed it to stand without correcting it.

Read more: What’s behind the rise in shareholder class actions

It argued the statement inflated the share price, causing buyers to pay too much for the shares and to lose money when the true state of affairs became known.

Myer argued it had no obligation to update the market after Brooke’s statement.

It said the market had already realised the profit would be lower than what he said. And, in any event, what he said was not misleading.

What Myer was obliged to do

The Corporations Act Section 1041E states that people must not make a false or misleading statement that is likely to (among other things) influence trading activity or market prices when that person knows, or ought to know, that the statement is not correct, or does not care whether the statement is correct.

Similarly, Section 1041H asserts that a person must not engage in misleading or deceptive conduct, which could include failing to correct erroneous statements.

Indeed, Section 769C says if a statement is made without reasonable grounds, it is deemed to be misleading.

Corporations Act Section 1041I says anyone who has suffered loss or damage by a contravention of the aforementioned rules can recover the amount of that loss or damage.

Read more: Explainer: what exactly must companies disclose to investors?

Also, Corporations Act Section 674 says firms must comply with continuous disclosure requirements, which include disclosing material price-sensitive information. The provision gives legislative force to the Securities Exchange continuous disclosure guidelines.

There are two overarching elements involved in securities litigation, both of which were issues in the Myer case:

• the defendant makes a false or misleading statement

• that false statement causes the plaintiff to suffer loss or damage.

Each needs exploring.

False or misleading?

At first glance, a statement is false or misleading merely if it is incorrect, especially so if it is about something currently known. But things are less clear when the statement is about the future or a forecast.

Under Section 769C, forecasts are held to be misleading if they are not based on reasonable grounds. Omitting information, or failing to correct information, can also be misleading if it creates or maintains a false impression.

Loss or damage?

Historically, in fraud type cases, the plaintiffs need to show that they “relied” on the false statement in making a decision. That is, they need to show they were directly misled.

Myer argued that the shareholders needed to show they actively “relied” on its statements when deciding to purchase shares.

The shareholders argued that the legislation does not require active reliance. They argued that it was enough to show that the false statement inflated the share price and that they bought at a price that was too high.

It was a win and a loss…

The court sided with the plaintiffs, finding that it was enough for them to show that the false statement (or misleading omission) inflated the share price, that they bought at a price that was too high, and they suffered a loss when the truth was revealed.

And it found Myer had been misleading by failing to correct a forecast it knew was erroneous. It had also violated the Exchange’s continuous disclosure standards.

But it found that Myer’s September 11 2014 forecast was not misleading at the time. It was in line with analysts’ forecasts, and in September 2014 Myer had reasonable grounds to make it.

Damages would normally reflect the difference between what the shareholders paid and what they would have paid if the true state of affairs had been known.

But given the market, notwithstanding the statement form the Myer chief executive, knew about Myer’s declining profitability and given that that information was reflected in the price, shareholders weren’t damaged.

…with implications for the future

The judgment will make future shareholder class actions easier. They will know what they have to prove.

An unanswered question is whether Myer will simply get away with having misled the market, given that it prevailed in the case.

It may not. Regulators – such as the Australian Securities and Investments Commission – still have penalty mechanisms they can use to punish officers and directors for misleading conduct, even if shareholders don’t prevail in court.

As the east coast bushfire crisis unfolds, New South Wales Premier Gladys Berejiklian and Rural Fire Service operational officer Brett Taylor have each warned residents bushfires can create their own weather systems.

This is not just a figure of speech or a general warning about the unpredictability of intense fires. Bushfires genuinely can create their own weather systems: a phenomenon known variously as firestorms, pyroclouds or, in meteorology-speak, pyrocumulonimbus.

Read more: Firestorms: the bushfire/thunderstorm hybrids we urgently need to understand

The occurrence of firestorms is increasing in Australia; there have been more than 50 in the period 2001-18. During a six-week period earlier this year, 18 confirmed pyrocumulonimbus formed, mainly over the Victorian High Country.

Its not clear whether the current bushfires will spawn any firestorms. But with the frequency of extreme fires set to increase due to hotter and drier conditions, it’s worth taking a closer look at how firestorms happen, and what effects they produce.

What is a firestorm?

The term “firestorm” is a contraction of “fire thunderstorm”. In simple terms, they are thunderstorms generated by the heat from a bushfire.

In stark contrast to typical bushfires, which are relatively easy to predict and are driven by the prevailing wind, firestorms tend to form above unusually large and intense fires.

If a fire encompasses a large enough area (called “deep flaming”), the upward movement of hot air can cause the fire to interact with the atmosphere above it, potentially forming a pyrocloud. This consists of smoke and ash in the smoke plume, and water vapour in the cloud above.

If the conditions are not too severe, the fire may produce a cloud called a pyrocumulus, which is simply a cloud that forms over the fire. These are typically benign and do not affect conditions on the ground.

But if the fire is particularly large or intense, or if the atmosphere above it is unstable, this process can give birth to a pyrocumulonimbus – and that is an entirely more malevolent beast.

What effects do firestorms produce?

A pyrocumulonibus cloud is much like a normal thunderstorm that forms on a hot summer’s day. The crucial difference here is that this upward movement is caused by the heat from the fire, rather than simply heat radiating from the ground.

Conventional thunderclouds and pyrocumulonimbus share similar characteristics. Both form an anvil-shaped cloud that extends high into the troposphere (the lower 10-15km of the atmosphere) and may even reach into the stratosphere beyond.

The weather underneath these clouds can be fierce. As the cloud forms, the circulating air creates strong winds with dangerous, erratic “downbursts” – vertical blasts of air that hit the ground and scatter in all directions.

In the case of a pyrocumulonimbus, these downbursts have the added effect of bringing dry air down to the surface beneath the fire. The swirling winds can also carry embers over huge distances. Ember attack has been identified as the main cause of property loss in bushfires, and the unpredictable downbursts make it impossible to determine which direction the wind will blow across the ground. The wind direction may suddenly change, catching people off guard.

Firestorms also produce dry lightning, potentially sparking new fires, which may then merge or coalesce into a larger flaming zone.

In rare cases, a firestorm can even morph into a “fire tornado”. This is formed from the rotating winds in the convective column of a pyrocumulonimbus. They are attached to the firestorm and can therefore lift off the ground.

This happened during the infamous January 2003 Canberra bushfires, when a pyrotornado tore a path near Mount Arawang in the suburb of Kambah.

Understandably, firestorms are the most dangerous and unpredictable manifestations of a bushfire, and are impossible to suppress or control. As such, it is vital to evacuate these areas early, to avoid sending fire personnel into extremely dangerous areas.

The challenge is to identify the triggers that cause fires to develop into firestorms. Our research at UNSW, in collaboration with fire agencies, has made considerable progress in identifying these factors. They include “eruptive fire behaviour”, where instead of a steady rate of fire spread, once a fire interacts with a slope, the plume may attach to the ground and rapidly accelerate up the hill.

Another process, called “vorticity-driven lateral spread”, has also been recognised as a good indicator of potential fire blow-up. This occurs when a fire spreads laterally along a ridge line instead of following the direction of the wind.

Although further refinement is still needed, this kind of knowledge could greatly improve decision-making processes on when and where to deploy on-ground fire crews, and when to evacuate before the situation turns deadly.

More than 2,000 people in the United States have developed serious lung damage in a poisoning outbreak associated with the use of vaping devices this year. At least 39 people have died from the condition.

Most of those affected are young men. Their symptoms, which developed over a few days to several weeks, included cough, shortness of breath, chest pain, nausea, vomiting, abdominal pain, diarrhoea, fever, chills, and weight loss.

The United States Centers for Disease Control and Prevention (CDC) has recently named this combination of symptoms – “e-cigarette or vaping product use associated lung injury”, or EVALI.

Importantly, they’ve now implicated vitamin E acetate, an ingredient added to illicit cannabis vaping liquids, as the most likely cause of EVALI.

1. What EVALI is and how it’s diagnosed

EVALI cases are characterised by pneumonitis (lung inflammation). Some cases have involved the accumulation of oil in the lungs, while others have involved an accumulation of white blood cells – a marker of the immune system responding to a threat.

To be classified as EVALI, cases have to satisfy the following criteria:

• having vaped or “dabbed” (inhaled a concentrated cannabis product) in the 90 days before symptoms started
• a chest image showing the presence of a substance denser than air in the lungs (pulmonary infiltrates) or pathology confirming acute lung injury
• absence of lung infection or any alternative plausible medical diagnosis that explains the symptoms.

2. Why this new diagnosis was needed

When investigating the causes of an outbreak like this, it’s important to have a clear definition that determines who is and who is not likely to be part of the outbreak.

For example, some people who vape may develop similar symptoms from other lung conditions unrelated to vaping (for example, they may have influenza, or chronic obstructive pulmonary disease due to a history of cigarette smoking).

If these people were included as outbreak cases it would be more difficult to identify the cause of EVALI.

3. The cause of EVALI

Cases have followed a typical acute outbreak pattern, with most occurring over a number of months. The peak was in September this year when 463 cases were admitted to hospitals.

This pattern indicates EVALI is a form of acute poisoning, rather than a condition that has developed from chronic vaping over many years. It’s most likely there’s something new in vaping products used by these patients that’s caused the spike in lung injuries.

Read more: How a person vapes, not just what a person vapes, could also play a big role in vaping harm

Most people with EVALI have either admitted using, or later been found to have vaped products containing tetrahydrocannabinol (THC), the major psychoactive ingredient in cannabis. They have typically purchased these products from illicit sources.

Laboratory analyses of THC vaping product samples supplied by EVALI cases have found many of these contain vitamin E acetate (oil). Vitamin E acetate is sometimes added to illicit THC vaping products to dilute and then thicken the liquid to hide the dilution, in the same way other illicit drugs are “cut” with other substances to reduce their purity.

The CDC tested fluid samples collected from the lungs of 29 EVALI cases and found all samples contained vitamin E acetate.

One theory is the oil may be the direct cause of the lung injury, because some of these patients have been diagnosed with lipoid pneumonia (lung inflammation associated with oil inhalation). However, it increasingly looks like a chemical formed from the vitamin E acetate may be causing the toxicity. Research is continuing to test this hypothesis.

It appears increasingly unlikely standard commercially produced nicotine vaping products are a cause of EVALI.

Of 849 EVALI patients who provided information about the products they used, only 10% reported exclusive use of nicotine-containing products, while 78% reported using THC-containing products. Some EVALI patients who initially denied using THC vaping products were later found to have used them.

EVALI has not been evident in other countries with widespread use of nicotine vaping products but little use of THC vaping products, such as the UK.

4. How EVALI can be treated

Many patients with EVALI have developed a severe illness that requires hospitalisation. In the most serious cases, treatment has involved intubation and mechanical ventilation because the patient cannot breathe on their own.

Most patients have been treated with corticosteroids to reduce the inflammation on the lungs. Antiviral and antibiotic medicines may also be given on a case-by-case basis.

EVALI patients are strongly advised to avoid vaping and cigarette smoking, so treatment may be needed to address dependence on nicotine and/or cannabis, such as behavioural support and non-inhaled nicotine replacement therapies like nicotine gum and patches.

5. How you can avoid EVALI

The US authorities recommend consumers do not use any cannabis or THC vaping products, especially those purchased illegally.

Only one EVALI case has been reported outside the US, in Canada, but it’s difficult to rule out the possibility illicit THC vaping products sold in other countries may also be contaminated with the causative agent.

Review: The Dark Master and Totes Adorbs ♥ Hurricane, OzAsia Festival, Adelaide, 22 October – 8 November

In theatre, the play text tends to drive the storytelling. The interpretation of this text, known as dramaturgy, determines the artists’ approaches to dialogue, characterisation, movement, set design, and other production elements. Dramaturgy’s purpose is to help the audience imagine a world on stage, and to understand how this world works.

In some performances, however, the visual production elements – not the text – take the lead in creating the world on stage. This visual dramaturgy enables artists to present alternative narratives by stimulating the spectators’ emotional and physical engagement and by creating immersive experiences.

Visual dramaturgy has been part of Japanese performance culture for centuries. Its reliance on spectacle is responsible for the popularity of kabuki dance-drama, which many believe gave rise to fan culture in Japan. The close spectator-performer relationships in kabuki became possible through innovations in theatre architecture, especially the hanamichi, a rampway extending into the auditorium.

More recently, we can see the importance of visual storytelling in Japanese culture in manga, where emotional intensity and supernatural encounters are presented as something quite palpable. While western comics and graphic novels tend to favour dialogue-driven action, in manga, visual representations of characters and their emotional and physical states take centre stage.

Visual dramaturgy remains central for contemporary artists in Japan, as was thrillingly demonstrated through two key works at this year’s OzAsia festival

The Dark Master

The Dark Master is Kuro Tanino’s stage adaptation of a manga of the same title. Presented by theatre group Niwa Gekidan Penino, it is set in Osaka at a small traditional eatery catering mostly to locals, who come to enjoy a delicious meal, read a newspaper or watch a baseball game over a beer.

The chef/owner (Susumu Ogata) is getting on in years. Though his desire to cook remains strong, his body is beginning to give up on him. At least, this is what he tells the 28-year-old Tokyo backpacker (Koichiro F.O. Pereira) who stumbles in one evening, hungry and in search of adventure.

The chef seizes the opportunity to recruit his replacement. So does the eatery: the front door locks by itself, thwarting the young man’s attempts to leave. The backpacker becomes the eatery’s new owner. The chef withdraws to the second floor, never to be seen again. However, for the next 33 days, he will give his apprentice cooking lessons via a minute earpiece planted in his ear. The arrangement is exhilarating and unnerving.

The audiences’ sensory engagement deepens when appetising smells (the cooking on stage is real) mingle with live, multi-angle video projections showing the young man’s training. Through our own earpieces, we listen in on the chef’s covert cooking instructions, responding with gasps and laughter to comic blunder and culinary spectacle. Surtitles on separate screens provide translation.

Visual dramaturgy produces a hyperreal, immersive experience akin to becoming one with the young chef.

Totes Adorbs ♥ Hurricane

Delight in experiencing Totes Adorbs ♥ Hurricane, the latest work from Toko Nikaido’s Miss Revolutionary Idol Berserker, comes partly from sheer astonishment: did that angel just shoot me with a water rifle? Are they flinging around tofu and … seaweed?!

The performers’ frenzied dance numbers give a tantalising nod to berserker warriors in Scandinavian mythology who would shape-shift to non-human form in the frenzy of battle.

We are all transformed into pop-culture berserkers.

Performers and spectators alike are whirled into a shrine to partake in a euphoric spectacle amid pop-culture icons and idols: skeleton spectres in the woodblock prints of Kuniyoshi Utagawa appear side by side with anime, video-game characters, and animoji. Digital projections flicker past continuously in a deliberate overload of colour, lights, and glitter.

What appears on the surface as unruly indulgence conceals the careful choreography of dance sequences, songs, and the swift on-stage transformations – hengemono – associated with the best of visual dramaturgy in kabuki. Performers character-shift before our eyes, flinging discarded costumes into the audience. Also carefully choreographed is this audience: we are ingeniously drawn into the spectacle, transforming into the actors of our dreams.

Meaning where logic fails

The Dark Master and Totes Adorbs ♥ Hurricane reflect two disparate arms of contemporary Japanese performance: one of hyperreal theatre, and one of underground idol performance. Yet they both showcase the immense creative potential of visuals to create meaning on stage.

When visual dramaturgy leads, the spectators’ sensory and physical engagement cuts through performance conventions and helps us discover meaning in those in-between states and spaces, where experiences ring true even when language and logic fail.

Review: OzAsia Festival, Adelaide, 22 October – 8 November

The most exciting work at OzAsia cuts across genres, styles, and cultures to create something distinctive and new: a work of art that could not exist without equality in the exchange between Western and Asian cultures. Under artistic director Joseph Mitchell, this brief has extended to engagement with the Middle East.

Perhaps because dance exists without language it has long been the place where Asia and the West have met most successfully. But funding and time are required to make such deep engagement between cultures possible. No surprise, then, Europe has become the centre for the generation of such work and three of the most outstanding works in this year’s festival were by European-based choreographers.

Two are of South Asian or Middle Eastern heritage while the third has a long history of deep engagement with Asia.

What the Day Owes to the Night

French choreographer Hervé Koubi grew up without full knowledge of his Algerian roots. His thrilling What the Day Owes to the Night reflects his coming to terms with that knowledge.

Working with non-professional dancers, hip-hop and breakdancing from the streets of North Africa link up with Afro-Brazilian capoeira, wrapped in the spectacle of Sufi-style, whirling dervish dance.

The superbly fit and athletic all-male cast are shirtless. Skirts billow out when they twirl: patterns of extraordinary beauty and complexity. Perpetual motion, they twirl for impossible periods of time upside down on their heads.

The work is explosive and powerful. Bodies are thrown into the air and across the stage. The dancers are superbly masculine, but also graceful and generous with one another. It was a work that overwhelmed the senses in its technical genius, exuberance, and joy.

Vessel

Belgian choreographer Damien Jalet’s Vessel extends from a collaboration with Japanese sculptor Kohei Nawa, exploring the ways dance and sculpture can come together.

The stage is a shallow pool of water surrounding a thin sculptural object, stark in its whiteness, resembling the top of a volcano. Dancers appear as non-human: heads tucked in front or behind, completely out of view. These headless forms attach to one another, fuse, and are expelled by some mysterious organic force.

It is a hypnotic evocation of the power of Japan’s volcanic islands, reflecting Jalet’s long-standing personal connection with Japanese aesthetics, myth and religion.

Japanese cultural and religious systems reflect the natural world. In Vessel, organisms are perilously fragile. They are birthed, mutated, and expelled over moments in a larger cosmic time. We are in a state of altered consciousness. Anything is possible.

Outwitting the Devil

Akram Khan, born in the UK of Bangladeshi parents, has a long history of work that extends the choreographic language of traditional dance forms. Building on the North Indian classical dance form of kathak, communicating stories through gesture and movement, he has generated a new kind of contemporary dance.

Outwitting the Devil draws on the Epic of Gilgamesh to offer a parable for our times. A tale of violence where a powerful, proud man unleashes terrible forces by taking on the natural world. Ultimately, all is lost. Nothing remains of civilisation except smouldering ruins.

Khan offers a model for how dance can fuse cultures and movement vocabularies to create something new that defies categorisation.

Mythili Prakash uses the angular vocabulary of Bharata Natyam, descended from Hindu temple dancing; Jasper Narvaez’s fluid movement and effortless leaps reflect his training at the Ballet Philippines Dance School; Sam Asa Pratt’s commanding physical presence extends from his background in hip-hop; James Vu Anh Pham’s movement, seemingly outside the range of human possibility, draws from many years of working with contemporary dance company Chunky Move.

This is intercultural work in which the dance cultures embedded in the bodies of performers is essential to the telling of the story.

Visceral performance

These works are intensely visceral. What the Day Owes to the Night produced a whirling, vibrating energy that remained in the body after the show. Jalet’s Vessel unfolded like an organism over geological time and Khan’s work ended with epic destruction and nearly unbearable sadness and heartbreak: both felt like they had permanently rearranged my DNA.

All show how works by master choreographers living outside of the Asia-Pacific region can successfully fuse Asian and Middle Eastern aesthetics and sensibilities and generate new stories and ways of moving. Koubi’s work a desert ritual, Jalet’s the forces of nature, and Khan’s the fall of civilisation.

When these elements are harnessed by thought, care, openness and generosity of spirit, and when the time needed to create such work is funded, what dance can do for the human spirit and soul is revealed.
