Help to settle in and friendships beyond class: what makes students feel like they belong at uni

Belonging is about feeling accepted, included and valued.

If students feel like they belong at their university, research shows it plays a crucial role in their overall wellbeing, self-esteem, and motivation to study.

As the Universities Accord interim report says, universities have an “obligation to students to foster belonging”. The draft report also notes “too few” Australians are completing university degrees, with completions of a first bachelor degree “at their lowest since 2014”.

Beyond ensuring campuses are safe and inclusive places to study, our new research looks at what factors can predict a sense of belonging for students.

What is happening to student belonging?

The annual Student Experience Survey tracks Australian students’ sense of belonging to their institution.

In 2022, only 46.5% of undergraduate students said they experienced a sense of belonging at university, and while this is slightly higher than 2021 (42.1%), it remains significantly lower than most other areas of student experience. For example, Australian students rated their overall university experience at 75.9%.

The pandemic and the move to more online teaching certainly had an impact on belonging. But this issue pre-dates 2020 and is not unique to Australia.

It is important to reverse this trend. Feeling like they belong can help students overcome challenges and hardships and guard against not completing their degrees.

Our study

Our research uses data from the Student Experience Survey between 2013 and 2019. We looked at more than 1.1 million undergraduate and postgraduate students during this time.

We used machine learning – a form of artificial intelligence that uses data and algorithms to progressively improve its quality (just like Netflix’s ability to recommend movies based on previous viewing) – to ask what actually predicts student belonging?

Analysis of multiple variables from the national student experience survey suggested several causes and connections.

Students want help to settle in

Students want to know they are welcome at their university from the very start. Our research found support for settling in was an important predictor for belonging.

This can mean inductions, orientations and structured opportunities to meet people. This could look like peer mentoring programs and for international students, mobilising the help of ethnic and religious community organisations.

It is also important for universities to have places on campus for students to interact, as well as clubs and events. On top of this, university teaching staff can complete training in how to facilitate social connections between students.

Our study found ease and helpfulness of enrolment and administration systems were not as important to belonging when compared to human connections.

Students need meaningful connections

Our research also showed students wanted to interact with their peers.

But we found interactions outside of class were much more important than interaction in class. This might be because student connection opportunities in class may be poor, or they see on-campus socialising as easier without academic pressure.

The study found it was important for all students – domestic or international – to have interactions with local students.

Local students already know the important places, events and sub-cultures of an area. This may be as simple as where to get the best coffee or cheapest takeaway, but helps students feel like they belong in the community.

Group work and belonging

We found some interactions in class are important: our study suggests learning teamwork in class helped students feel like they belonged as it meant students were working together and interacting with their peers.

However, other skills such as problem solving, critical thinking, subject matter knowledge, and work readiness were far less important when it came to belonging.

Demographic indifference?

Research says a student’s personal identity is an important precursor to belonging. That is, we might belong more easily with those who share characteristics with us.

In our study we looked at students’ age, gender and enrolment type.

But we found these were less significant when it came to belonging. It mattered more if students were able to interact with other students.

Why this matters

While skills development and subject matter expertise are very important for academic outcomes, our research shows when it comes to belonging, students need authentic opportunities to settle into university life and make friends.

In its interim report, the Universities Accord does not look at the commencement or orientation process for students.

It’s final report in December should not miss the opportunity to boost belonging – and thus retention – by focusing on how campuses can include and involve students from the start of their studies. If they do, our research suggests this will have long-term benefits.

Ned Kelly’s descendants claim cultural heritage rights over the site of his last stand. The Supreme Court disagrees

Source: The Conversation (Au and NZ) – By Bonny Cassidy, Senior Lecturer in Creative Writing, RMIT University

The Victorian Supreme Court has determined the descendants of Ned Kelly’s family are not a distinctive cultural group with the right to protections of their “intangible cultural heritage”.

The Kelly clan’s bid for recognition was provoked by a proposed tourist development at Glenrowan, the site of the outlaw’s last stand in 1880. The new centre will look at the story of the Kelly gang in the context of Glenrowan’s broader history.

Kelly’s grand-niece, Joanne Griffiths, argues the new structure and landscaping will “disrespect” her family’s “human rights” as cultural “custodians”.

Justice Melinda Richards found Griffiths and the family could not prove practices that would distinguish them as a cultural group. The redevelopment continues as proposed.

Griffiths has claimed the court’s decision is a continuation of the “persecution” meted out to the Kelly family:

If we were Indigenous this wouldn’t be happening.

The case raises fascinating questions about the definition and evidence of White cultural heritage in Australia – and the way we treat sites of colonial history.

Friday essay: how a ‘gonzo’ press gang forged the Ned Kelly legend


What is White cultural history?

Glenrowan is tucked inside the south-eastern boundary of Yorta Yorta Country, where the Ovens River floodplains meet the rising foothills of the Victorian Alps.

In 1998, the Yorta Yorta were denied native title because, according to Justice Howard Olney, “the tide of history has undoubtedly washed away any traditional rights” to their lands and waters.

The Kelly descendants made no claim to native title. But by invoking their cultural heritage they tasked themselves with the same burden of proof required of First Nations people in fighting for land rights.

The Kelly descendants were not claiming the site as one of public significance. They were instead claiming a familial connection.

There is no doubt Ned Kelly’s descendants share a unique emotional relationship with Glenrowan. That needs no justification or proof.

Many non-Indigenous people like myself feel close to certain places in Australia.

Historian James E Young coined the term “collected memory” rather than “collective memory”.

“A society’s memory,” he says, “might be regarded as an aggregate collection of its members’ many, often competing memories.”

Several Australian authors have explored this collected memory. Luke Stegemann’s Amnesia Road investigates the entanglement of Stegemann’s life and work in the colonial histories of Queensland and Andalusia. Dean Ashenden’s Telling Tennant’s Story examines how the place of his upbringing embodies the impacts of settler colonial legislation.

Collected memory is also enacted in memorials – the statue of politician William Crowther in nipaluna/Hobart is being removed so only the plinth will remain, with signage explaining his contentious history – and in public rituals like Survival Day Dawn Services.

As well as lacking recognition of the Yorta Yorta struggle, the Kelly family’s bid overlooks the ongoing critique by historians like David Dufty of Ned Kelly’s story as a tale of “persecution”.

Anti-Irish racism notwithstanding, Dufty highlights Kelly’s ruthless violence, use of terror in taking hostages and incoherent politics.

By asking what is distinctive about the Kelly descendants’ right to cultural protections, we are echoing a question posed by Gunditjmara artist Paola Balla:

Tell me what it means to be a white person […] beyond a notion of racial superiority.

White cultural heritage in Australia is made of many memories and histories that intersect with one another, with settlers of colour and with First Nations people.

How we commemorate colonial history

Cases like these raise interesting questions about how we identify – and memorialise – shared heritage.

If the Kelly family took a more nuanced position, they could have opened a public conversation about how we commemorate colonial history, the nuances of historical Irish-Blak solidarities, and a deeper sense of White allyship to First Nations people’s human rights.

With its Big Ned, bark hut museum and janky animatronic diorama, Glenrowan is currently a prime example of what writer and artist Melody Paloma defines as “settler kitsch”.

In Australia, the development of monuments to colonial history continues to be a work in progress.

The proposed development is a chance for a more complex presentation of colonial heritage. The Sovereign Hill living museum is working to illuminate the culturally diverse stories of Ballarat. The Tasmanian Museum and Art Gallery has also sought to face its past by recentering its public program and exhibition spaces around First Nations and particularly Palawa art and culture.

Photographer Jon Rhodes has spent decades documenting the curious histories of municipal and community treatment of sites of First Nations’ cultural heritage, and colonial violence.

An outlier, the Myall Creek Massacre Memorial offers a deeply affective model of how such sites of shared cultural heritage can be rebuilt and maintained by White and Blak communities together.

Perhaps Glenrowan will come to be understood as one such place: always Yorta Yorta; for a moment a place of complicated anti-colonial, White-on-White rebellion; later, a carnival of settler kitsch; and eventually, maybe, a thoughtful site of ongoing history-telling, embedded in Country.

Developments like the one coming to Glenrowan could create tangible answers to the question of what an inclusive and informed experience of White cultural heritage might look like.

What does ‘infanticide’ mean in NZ law? And what must the jury decide in Lauren Dickason’s trial?

Source: The Conversation (Au and NZ) – By Kris Gledhill, Professor of Law, Auckland University of Technology

Lauren Dickason is being tried at the Christchurch High Court. Getty Images

Lawyers are fussy about language because it is their job to argue about its implications. The current trial of Lauren Dickason is a case in point, and the jury has a complex task in front of it.

Dickason is charged with the murder of her three young children. She denies the charges, with her defence seeking findings of “insanity” and “infanticide”. The latter may seem like a statement of the obvious, given Dickason does not deny the killings. But the word has a very distinct meaning in law.

What legislation and other sources of law mean is often contestable, and there may be specialised definitions. An added complication is that the rules and words in play may have been formulated decades ago.

This is often the case in criminal law, including the law of homicide and the law relating to insanity. Since homicide trials often have a high profile, public understanding of these complications is important.

Murder and manslaughter

New Zealand’s main homicide law is found in the Crimes Act 1961. But the language used reflects a structure that goes back to English law from centuries ago, and is split into two offences: murder and manslaughter.

Basically, murder is killing someone with “malice aforethought”, and manslaughter is any other culpable killing. (A killing will not be homicide if there is a justification, such as reasonable force in self-defence.)

There were originally three types of malice. “Express malice” was a deliberate killing. “Implied malice” was when the person intended serious harm and showed a lack of care for human life. “Constructive malice”, which appears in US TV shows as the “felony murder rule”, arose from killing when committing another violent offence.

With updated language, we still have that basic structure in New Zealand. But variations were introduced largely to avoid the formerly mandatory death penalty for murder, by allowing the offence to be stepped down to manslaughter.

These are sometimes referred to as “defences” to murder, but they are only partially so because they lead to conviction of another offence.

So, if the person charged was part of a mutual suicide agreement, that is expressly classified as manslaughter. We used also to allow provocation to turn a killing into manslaughter, though only if a reasonable person would also have lost self-control.

That condition was removed after Clayton Weatherston tried to use it in his trial for the 2008 murder of Sophie Elliott.

Infanticide and insanity

Some other countries also allow a manslaughter conviction where someone has a mental disorder that reduces their moral culpability for a killing. New Zealand has never had such “diminished responsibility” – except in relation to infanticide.

Infanticide has a legalistic meaning in the courtroom: it does not mean the killing of an infant. Rather, it is an offence that can only be committed by a woman.

Secondly, it must involve a child of that woman who is under ten years of age. It must involve what would otherwise have been murder or manslaughter.

Crucially, the jury must find that that the woman “should not be held fully responsible” because of the extent to which “the balance of her mind was disturbed” from the effects of childbirth, lactation or any disorder caused by childbirth or lactation.

If this series of steps is met, then the offence is called infanticide, which carries a maximum sentence of three years.

But the legislation also notes that if the defendant’s disorder was so great that there was insanity, then there must be a “special verdict of acquittal on account of insanity caused by childbirth”.

Modern psychiatry and Victorian language

The law relating to insanity still uses language from Victorian times. It applies to all offences, though it is most prominently used in homicide cases.

It requires “natural imbecility or disease of the mind” producing a situation in which the defendant does not know what they are doing, or does not know that it is morally wrong. Clouded understandings do not amount to insanity.




Read more:
How the insanity defence against a murder charge works


It is not limited to disorders arising from childbirth: that is an overlap only in an infanticide setting. The doctors giving expert evidence have to try to mould modern understandings of psychiatry into this outdated legal framework, which has limited nuance to it.

A finding of insanity used to lead to the special verdict of “not guilty by reason of insanity”, which in turn usually led to detention in a psychiatric setting. The Rights for Victims of Insane Offenders Act 2021 means the verdict is now “act proven but not criminally responsible on account of insanity”, though with the same consequences.

Can juries still deliver justice in high-profile cases in the age of social media?


The jury’s challenge

The task for the jury in the Lauren Dickason trial is not helped by the outdated language, however calmly and professionally the judge seeks to explain it.

Having considered whether the deaths would otherwise have been murder or manslaughter, they will then have to consider whether the expert evidence shows there was some disturbance in her mental health.

If so, and if it was caused by childbirth or lactation, was it far enough down the line to amount to infanticide? Or did it go so far as to amount to insanity? The latter can also arise from a mental disorder not linked to childbirth.

This complexity is a good illustration of why we should value only the opinion of those who hear all the evidence, and who have the task of deciding the verdict.

Morrison labels Robodebt findings against him unsubstantiated and absurd and accuses government ‘lynching’ campaign

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

Scott Morrison has accused the Robodebt royal commission of making wrong, unsubstantiated and absurd findings against him, in a detailed statement to parliament.

The former prime minister, who was excoriated by the commission, was unrepentant, giving no ground on any of the criticisms Commissioner Catherine Holmes made of him in her report.

He also accused the government of a “campaign of political lynching” to discredit him and his service to the country, once again weaponising “a quasi-legal process to launder [its] political vindictiveness”.

Rising on the first sitting day after the report’s release during the recess Morrison, speaking to a near-empty house, said he rejected the commission’s findings he had allowed cabinet to be misled, provided untrue evidence, and pressured departmental officials.

Morrison was social services minister when the scheme, announced in the 2015 budget, was being worked up. He was an enthusiast for pursuing savings in the welfare area and saw the plan, based on income averaging, as a powerful means to do this.

But the scheme was found to be illegal and, by the time he was prime minister, it had raised $1.76 billion unlawfully from hundreds of thousand of people, and the government was forced to repay a huge amount in total to people wrongfully pursued for money they didn’t owe.

In his statement, Morrison reiterated that when he was social services minister and the plan was being prepared, the final advice to him was that legislation was not required, and he had no reason to doubt the integrity and knowledge of officials. This superceded an earlier minute indicating legislation could be needed.

The commission’s suggestion it was reasonable he would or should have formed a contrary view to this advice was “not credible or reasonable,” Morrison told parliament.

He said when the scheme was announced in the 2015 budget, the Labor opposition did not express concerns about its legality.

“The commission’s finding unfairly and retroactively applies a consensus of the understanding of the lawful status of the scheme that simply was not present or communicated at the time,” Morrison said. “This is clearly an unreasonable, untenable and false basis to make the serious allegation of allowing cabinet to be misled.”

Morrison said the commission’s finding he had given untrue evidence was “unsubstantiated, speculative and wrong”, with the commission seeking to reverse the onus of proof. “I had stated in evidence what I understood to be true, the commission failed to disprove this and simply asserted it unilaterally as fact.”

Arguing the commission’s allegation pressure was applied to officials that prevented them giving frank advice was “absurd”, Morrison said the department had already initiated the proposal before he arrived as minister. “How could I have pressured officials into developing such proposals, while serving in another portfolio?”, he said. “The department had already taken the initiative and were the proponents of the scheme.”

Further, “the Commission’s suggestion that an orthodox policy setting of seeking to ensure integrity in welfare payments would be seen as intimidating to the department and its senior executive is both surprising and concerning. That is their job.”

Morrison said that “at no time did the department advise me as minister of the existence of the formal legal advice prepared prior to my arrival in the portfolio, regarding the scheme.”

He said the “uncontested fact that senior departmental executives withheld key information regarding the legality of scheme from their minister is inexcusable.”

Morrison once again expressed his “deep regret” for the scheme’s “unintended consequences” on individuals and their families.

Opposition leader Peter Dutton told the ABC Morrison had put “a very strong case” of his position, and he had been right to put it in parliament.

The commission has referred a list of people involved in Robodebt for further action, but the names have not been released.

A key top bureaucrat involved in the scheme, Kathryn Campbell, has resigned from the public service in the wake of the report’s condemnation of her.

Viral room-temperature superconductor claims spark excitement – and skepticism

Source: The Conversation (Au and NZ) – By Mahboobeh Shahbazi, Senior Research Fellow, Materials Science, Queensland University of Technology

Hyun-Tak Kim

Last week, a group of South Korean physicists made a startling claim. In two papers uploaded to the arXiv preprint server, they say they have created a material that “opens a new era for humankind”.

LK-99, a lead-based compound, is purportedly a room-temperature, ambient-pressure superconductor. Such a material, which conducts electricity without any resistance under normal conditions, could have huge implications for energy generation and transmission, transport, computing and other areas of technology.

The papers have sparked wild enthusiasm online, and several efforts to replicate the work. At the same time, there are reports of disputes among the Korean researchers over whether the research should have been released at all.

Why superconductors are so super

When an electric current flows through an ordinary conductor like a copper wire, the electrons bump into atoms as they jostle along. As a result, the electrons lose some energy and the wire heats up.

In a superconductor, electrons move without any resistance. Superconducting wires can transmit electricity without losing energy, and superconducting magnets are powerful enough to levitate trains and contain the fierce plasmas in fusion reactors.

However, all known superconductors require very low temperatures (typically lower than –100 ℃) or extremely high pressures (more than 100,000 times ordinary atmospheric pressure). These restrictions make superconductors expensive and impractical for many applications.

Several teams of researchers have claimed to detect room-temperature superconductivity in various substances in the past, but none of the claims have withstood scrutiny. As recently as last week, a superconductivity paper by American physicist Ranga Dias was retracted amid suspicions of data fabrication.

So while a room-temperature superconductor would be an amazing discovery, we should meet the new claims with some skepticism.

Bold claims

The South Korean researchers say LK-99 can be made in a baking process that combines the minerals lanarkite (Pb₂SO₅) and copper phosphide (Cu₃P). They say the resulting material shows two key signs of superconductivity at normal air pressure and at temperatures up to 127 ℃: zero resistance and magnetic levitation.

They propose a plausible theory of how LK-99 might display room-temperature superconductivity, but have not provided definite experimental evidence. The data presented in the papers appear inconclusive.

One of the signatures of a superconductor is the Meissner effect, which causes it to levitate when placed above a magnet.

In a video demonstration, the researchers position a piece of LK-99 over a magnet. One edge of the flat disk of LK-99 rises, but the other edge appears to maintain contact with the magnet.

We would expect a superconductor to display full levitation and also “quantum locking” which keeps it in a fixed position relative to the magnet. In a charitable interpretation, the behaviour we see in the video may be due to imperfections in the sample, meaning only part of the sample becomes superconductive.

So it is too early to say we have been presented with compelling evidence for room-temperature superconductivity.

What’s next

At present, all we know about LK-99 comes from the two arXiv papers, which have not been peer-reviewed. Both papers present similar measurements, though the presentation is unconventional. However, there are some differences in the content, and also in authorship, which does not inspire confidence.

So what happens now? The processes of science swing into action.

Experts will closely review the papers. Researchers at other laboratories will attempt to reproduce the experiments described in the papers, and see whether they end up with a room-temperature superconductor.

These crucial steps are necessary to establish the validity and reliability of the LK-99 claims. If the claims are validated and confirmed, it could mark one of the most groundbreaking advancements in physics and materials engineering in the past few decades.

However, until the research undergoes rigorous review and testing, we should approach the claims with caution. We will all be awaiting the outcome of the verification process with great interest.

What Indiana Jones and the Dial of Destiny gets right (and very wrong) about the historical Antikythera Mechanism

Source: The Conversation (Au and NZ) – By Tatiana Bur, Lecturer in Classics, Australian National University

Disney/ Wikipedia

At the heart of the newest film in the Indiana Jones series lies “an ancient hunk of gears”. Indiana Jones and the Dial of Destiny is based around the Antikythera Mechanism: an actual ancient Greek object that tracked the cycles of the Sun, the Moon, and the planets against the stars.

The Antikythera mechanism and its bronze gearwheels totally reconfigured the study of ancient technology. It was among a bunch of other antiquities pulled out of a shipwreck by sponge divers in 1901. And it was tangible proof of a level of technological sophistication otherwise thought impossible for the first century BCE.

As a scholar of ancient Greek technology, seeing a blockbuster based around the Antikythera Mechanism is deeply satisfying. Moviegoers will leave the theatre with some facts about the Antikythera mechanism under their belt. Its fragmentary state. Its link to underwater archaeology. The complexity of the gears. The presence of Greek inscriptions. Its association with cosmology. The rival characters of physicist Voller and Jones even point to the way decoding the Antikythera mechanism has only been possible thanks to collaborations between science, archaeology, mathematics and ancient history.

As the movie progresses, the mechanism inevitably leaves the realm of history and enters fantasy. It becomes a time machine of sorts, used to predict “fissures in time”. Along the way, the film gives us a chance to reflect both on ancient technology in modern pop culture, and on our complex ongoing relationship with the Greeks and the Romans.

Archimedes and Nazis

The film begins with Nazi eyes initially set on a different object: the lance of Longinus. Once it is revealed the lance is a fake, there is some anxiety around how to present the far less snazzy relic of the Antikythera to Hitler instead. The sell for the film’s audience and for the Führer is Archimedes himself.

Today, this third century BCE mathematician from Syracuse is a household name. He is associated with inventions such as the Archimedes screw used to draw-up water in Assyria and Egypt. The eureka story accompanying his discovery of water displacement while taking a bath. Harnessing the power of the Sun to set Roman ships aflame. His theoretical dictum on the law of the lever. And as shown with Indie’s latest antics, the Antikythera mechanism can be added to the list of intriguing myths associated with the ancient mathematician.

In the film, Helena (Phoebe Waller-Bridge) steals the “device” in order to sell it at an illegal antiquities auction. Trying to hike up the price, Helena explains it was built by Archimedes himself. It’s one thing to attribute the design of the mechanism to Archimedes (some academic papers in fact toy with the same idea). But to imagine this renowned inventor figure physically putting the pieces of the gears together stretches even the best of the evidence. Notably, it completely removes the collaborative nature of ancient scientific practice.

It does, however, tell us a lot about how we tend to perceive ancient technology. It shows how badly we want to link historical inventions to a single genius from the past.

So what IS the Antikythera mechanism?

What survives of the mechanism is 82 bronze fragments – seven large and 75 small. Together these make up only one third of the original whole.

The Antikythera mechanism would not have been a disc as in the film, but rather a box covered in circles. On the back you could see two large spirals and three smaller dials which tracked the passing of time according to different calendars. There was also an inscription which acted as a kind of user manual.

On the front was large single dial of concentric circles with a number of pointers jutting out towards its very many inscribed segments. These pointers landed in different rings to indicate the phases of the Moon, the phases of the planets, the signs of the zodiac. Hiding inside this external shell was a complex arrangement of precision gears. These allowed a user to put the Antikythera mechanism into motion by carefully rotating a knob.

This portable machine was incredibly capable. It predicted eclipses according to a Babylonian cycle of the Moon. It reconciled various lunar cycles and three different types of calendar months. It matched the Greek zodiac scale with the Egyptian calendar.

This object brought together astronomical understandings from multiple cultures. It is physical proof of centuries of collaborative science.

The Antikythera mechanism, Hollywood, and Silicon Valley

Though this is the first time the mechanism has featured in a Hollywood blockbuster, the Antikythera has not been camera shy. From as early as the 1950s, the Antikythera mechanism was called a “computer” by scholars working on the device. This was quickly picked up by mainstream media.

In the last 15 years, the Antikythera mechanism has seen a revival of popular interest featuring in BBC Series, documentaries, articles (both scholarly and popular), YouTube videos as well as various museum exhibits around the world.

The common thread is that in looking at the Antikythera mechanism, you are looking at the “world’s first computer”. The same is often said of Homer’s Iliad predicting AI, and of ancient Greek automata being the world’s oldest robots.

This points to our obsession with drawing neat lines from the Greeks and the Romans to modern society.

Really, this tech saviourism does no-one any favours. It certainly does not do justice to the ancient object. It assumes that what drove ancient scientific pursuits is the same as what drives our own. It distracts us from understanding what the ancient object did in its context, how it was used, and what it meant to those using it.

Parents may wait up to 40 years to join family in Australia. Is a visa lottery the answer?

Source: The Conversation (Au and NZ) – By Peter Mares, Adjunct senior research fellow at Monash University’s School of Media Film and Journalism, Monash University

“Providing an opportunity for people to apply for a visa that will probably never come seems both cruel and unnecessary”.

This was the view of an expert panel, commissioned by Home Affairs Minister Clare O’Neil, on Australia’s dysfunctional parent migration system. Parents wanting to migrate to Australia to join their children face extreme delays, even if they can afford a contributory visa, which costs almost $50,000 per person.

My report for the Scanlon Foundation Research Institute, published today, finds the backlog of applications for permanent parent visas is approaching 140,000 and has tripled in a decade. Wait times for a contributory visa are at least 12 years, or at least 30 years for a cheaper visa.

How can we fix this? Whichever way the government turns, it faces unpalatable policy choices with unwanted electoral consequences.

The parent visa conundrum

The parent visa pipeline includes 86,000 applications for so-called “contributory” visas, and 51,000 for “non-contributory” visas.

These are first- and second-class migration options, with price tags to match.

The $47,955 per person charge for a contributory visa is justified on the basis that these first-class parents “contribute” to the cost of the public services they will access as they age. But the Productivity Commission argues the revenue raised is “a fraction of the fiscal costs” that parents will impose, especially by drawing on health services.

The charge is better understood as a premium paid in return for “quicker” processing. Initially, this worked. When the Howard government first introduced contributory visas in 2003, well-off families were able to swiftly settle parents in Australia, usually within two years. But program numbers were capped from the start, and demand rapidly outstripped supply.


Data to 2021-22 is from Home Affairs and its predecessor departments via annual reports on the migration program and the serial publication Population Flows: Immigration Aspects. Data for 2022-23 is to 30 May 2023, all other data is for 30 June, Author provided

In 2022-23, the Albanese government almost doubled the quota from 3,600 to 7,000 places.

Yet even with this higher cap, Home Affairs advises that a new application “may take at least 12 years to process” (their emphasis). The expert migration panel thought this an underestimate – its March report put the wait time at 15 years.

The cheaper, non-contributory visa has a far lower cap – just 1,500 places last financial year – and so the wait for a visa is even longer. Home Affairs advises that a new application “may take at least 29 years to process”. Again, the expert panel reckons this is optimistic. It estimates processing time at more than 40 years.

Such waiting times are ludicrous.

Parents are generally at least 60 years old when they apply. About 60% of parent migrants are women and often want to settle in Australia while they’re still fit and healthy, so they can enjoy time with young grandchildren and support their Australian children as they build careers.

Alternatively, parents may be recently widowed, isolated or in need of care themselves.

In either scenario, even the shortest wait time of 12 years defeats the purpose of the visa.

Can we fix it?

The panel recommended the government shift to a ballot system as New Zealand is now doing now, and as Canada did in 2015.

In Canada, for a limited time each year, families can lodge an expression of interest to sponsor a parent or grandparent to migrate to Canada. Immigration authorities then pull enough names from the hat to fill the annual intake quota. Once an application is accepted, the processing time for a visa is about 2.5 years, and costs are modest.

In 2022, Canada offered about 23,000 places from a pool of about 155,000 expressions of interest, meaning the odds of a winning ticket were about one in seven.

Is a lottery preferable to a queue? A ballot would be a fairer system than the two-tiered approach Australia operates, which provides a fast lane for the wealthy and a slow lane for everyone else (even though that “fast” lane is now clogged too).

The expert panel argued a ballot could eliminate massive application backlogs because the number of applicants chosen from the lottery would align with the number of available visa places. This obscures the fact that there are likely to be tens of thousands of families that enter the draw and fail to win.

Those families will try again the following year, and again in the years after that, but their chances of success will decline as ever more new hopefuls throw names into the hat.

These families may not be stuck in a queue, but they’re stuck in a disordered heap hoping to get lucky. Their situation wouldn’t be so different from the “cruel and unnecessary” plight of those families currently waiting for a visa that may never arrive. They would also be condemned to living with a mixture of hope, anxiety and uncertainty, unable to plan for the future.

In the outline of its migration strategy, the Albanese government focused on skilled migration, and promised reform of the family program “will be considered separately”.

The current system is failing, but there are no easy answers for the government.

It could abolish permanent parent migration altogether, and upset overseas-born Australians, many of whom vote in key marginal seats.

Or it could attempt to clear the backlog by increasing the cap on permanent parent migration by about 20,000 places annually. Amid an intractable housing crisis and unprecedented pressure on Australia’s health- and aged-care systems, this would hand the Coalition an emotive “big Australia” campaign stick to beat it with at the next election.

A ballot might look like a neat way of avoiding these two extremes, but it fails the key test of clarity. The slim chance of winning the visa lottery will leave families banking on dreams, rather than adjusting to the realities of their situation and fully settling in Australia.

Fire in northern Australia’s tropical savanna is a threat to endangered fairy-wrens

Wildfire threatens the survival of endangered purple-crowned fairy-wrens living along the rivers and creeks of northern Australia, our new research has found.

For almost two decades, we studied the fairy-wrens at a wildlife sanctuary in the far north of Western Australia.

Over this time, one low-intensity fire and one high-intensity fire burnt through our study site. Both occurred late in the wet season, when fires generally burn at lower intensity. But drought and weather conditions meant the second fire unexpectedly burnt at high intensity instead.

We wanted to find out what happened to the birds before, during and after each fire. We found even low-intensity burns reduced population density. As this species is a biological indicator of ecosystem health, our new research
can help fine-tune fire management practices, to reduce the extent and intensity of fires along waterways.

Savanna burning: carbon pays for conservation in northern Australia


Fire in the tropics

Fire is particularly common in tropical monsoonal savanna. The vegetation thrives during the wet season, then dries out over the dry season. This creates plenty of fuel late in the dry season, leading to frequent fires.

Deliberately introducing fire in the early dry season, when fires generally burn at low intensity, can reduce large intense wildfires later in the year. So fire management is often used for conservation and carbon farming.

Riparian zones provide vital habitat and support a range of species.

But approaches to fire management that best protect “riparian” communities are relatively poorly understood. Riparian zones are the strips of vegetation along creeks and rivers. They play an important role in tropical savanna landscapes. They support a highly diverse range of species, provide corridors for animals to move through the landscape, and form a cool refuge from heat and drought.

Unfortunately they are also particularly sensitive to fire, making it ever more urgent to better protect these key places.

Understanding how riparian fire affects the species that depend on waterway vegetation for their entire life cycle is a good place to start.

Fairy-wrens and fire

We study a population of 200-300 purple-crowned fairy-wrens (Malurus coronatus coronatus) along 15km of waterways.

Each bird in this population has been tagged with a unique small coloured leg band. This enables us to recognise individuals and follow them throughout their life.

We gather detailed information on bird survival, movement and reproduction. This is key to quantifying how – and to what extent – fire impacts populations.

High-intensity fire greatly reduced the quality of riparian habitat.

In our study we found both low-intensity and high-intensity fire reduced the number of fairy-wrens in the burnt areas for at least two and a half years. The effect of high-intensity fire was much stronger, reducing the number of fairy-wrens by half.

Next, we investigated what mechanism caused these declines. We showed birds did not move out of burnt habitat, probably because they live in such well-defined territories year-round.

Instead, we found the low-intensity fire reduced breeding success by 80% during and shortly after the fire.

The high-intensity fire caused a decline in wrens through a different mechanism. We found birds in the fire-affected area were no more likely to die during the fire itself than birds in adjacent unburnt areas. Yet, they were 30% more likely to die over the next two to eight months after the fire.

This is probably because the quality of the riparian habitat was greatly reduced by this fire, which may have made it harder for the birds to find food, cover from predators, or find protection from the heat in subsequent months.

Protecting riparian zones from fire

Wildfires are becoming more frequent and severe as climate change worsens. These changes are transforming natural systems and threatening the diversity of life on Earth. We saw this in Australia in 2019-20, when the Black Summer fires pushed many species closer to extinction.

More frequent and severe fire is forecast for riparian zones, for various reasons. For example, extended droughts as well as large flood events (which deposit woody debris as fuel for fire), increase the risk of severe riparian fires. Additionally, riparian strips can become a corridor for fire under certain conditions.

The challenge for land managers is to minimise the impact of fire when it eventually enters the riparian zone. We suggest fire management can be used to reduce the extent and intensity of riparian fires. In particular, we recommend introducing low-intensity burns parallel and perpendicular to riparian zones so they have minimal impact yet create breaks along these riparian corridors, to prevent large sections burning at once.

Our study indicates the high sensitivity of riparian zones to fire, even when fire occurs during the wet season and burns at low intensity. Our findings call for more consideration by fire managers of the effects of fire on riparian habitat, and for further research to enhance our understanding of savanna riparian fire biology.

What is food protein-induced enterocolitis syndrome or FPIES? And are more babies getting it?

Source: The Conversation (Au and NZ) – By Jennifer Koplin, Group Leader, Childhood Allergy & Epidemiology, The University of Queensland

Parents, carers and childcare settings are much more aware of food allergies than they once were. Precautions are taken and emergency plans can be developed for each child at risk of a reaction. But fewer people have heard of food protein-induced enterocolitis syndrome (FPIES).

FPIES is a poorly understood food allergy that mostly affects infants. It can be caused by a variety of foods including some not usually associated with food allergies like rice, oats and vegetables. Other causes are more typical of food allergies, like cow’s milk and egg. The most common symptom is profuse, repetitive vomiting one to four hours after eating the food.

Reactions can be dramatic and worrying for parents, with infants becoming pale, lethargic (sleepy) and floppy. In severe cases, infants develop dehydration and low blood pressure. The diagnosis is often not made the first time a reaction occurs, because of the wide range of diseases which can cause these symptoms and the time delay between when a trigger food is ingested and the onset of symptoms.

Until recently, FPIES was thought to be rare, but new evidence suggests it is more common than previously thought. The past decade has also seen significant research efforts trying to identify what part of the immune system is responsible for causing FPIES reactions, to identify better tests for diagnosis and management.

What is it that causes symptoms?

We don’t currently know much about the immune dysregulation that causes FPIES.

FPIES is classified as a non-IgE mediated food allergy, differing from other types of more common food allergy like peanut allergy, where reactions are caused by allergy antibodies that can be detected in the blood.

That also means medications used for treatment of these types of allergies (such as EpiPens and antihistamine) do not work in FPIES. Recent studies suggest another part of the immune system, called the innate system might be involved. This system is the body’s first line of defence against potential invaders. It includes bacteria that fights off bugs or injuries, rather than cells that adapt to respond to threats.

Missed cases?

Symptoms of FPIES can be mistaken for other conditions such as gastroenteritis (“gastro”), twisted bowel or serious blood infections. This can delay diagnosis.

Unlike most other types of food allergies, which have reactions caused by allergy antibodies, there is no blood test to diagnose FPIES. Diagnosis relies on careful clinical history and may require a specialised oral food challenge. This can involve removing foods suspected of causing a reaction from the diet and then reintroducing them one-by-one in planned stages under medical supervision.

I think my child has outgrown their food allergy. How can I be sure?


How common is FPIES and is it becoming more common?

Because it is under-recognised and difficult to diagnose, estimates of FPIES prevalence vary considerably – between 0.015% to 0.7% of infants.

Although data is sparse, some studies report an increase in rates of FPIES. A study of Australian and New Zealand hospital data reported hospital admissions had tripled for infants with symptoms consistent with potential FPIES between 1998 and 2014.

An increasing awareness of FPIES, as well as improvements in diagnosis, mean FPIES diagnoses may increase without a true increase in the condition. Different estimates of FPIES rates between countries (for example 0.15% in Australia and 0.7% in Spain) may be due to true differences or variations in diagnosis and reporting. More research is needed to understand these differences.

What foods trigger FPIES?

Different foods appear to commonly cause FPIES in different countries. In Australia, rice is the most reported FPIES trigger, with cow’s milk, soy and eggs also common. Cow’s milk is the most common reported trigger in the United States and Europe. Fish is a common trigger reported in Mediterranean countries, and increasingly reported as a cause of FPIES in older children and adults. It is unclear what causes these differences, which may only be partially explained by differences in infant feeding and weaning practices between countries.

Reactions often occur for the first time in infancy with the introduction of a new food, either on the first exposure or after the first few exposures. Most affected babies only react to a single food, although some foods cross-react. This means infants have a similar response to related foods such as with grains (rice and oats); cow’s milk and soy; fish and shellfish. Those with FPIES need to avoid the foods that trigger FPIES reactions, but there is often no need to avoid other non-related foods.

Most children will outgrow FPIES in their first few years of life. There appear to be differences in how quickly FPIES resolves depending on the trigger food, with cow’s milk and grains FPIES resolving more quickly than egg and seafood FPIES. Adults can also develop FPIES, however this is less common.

What to do if you suspect you or your child has FPIES

If you think that you or your child may have FPIES, talk to your doctor. They may recommend a referral to an allergist for assessment.

The next step may be developing an action plan for a FPIES reaction. For severe reactions, such as when an infant becomes dehydrated or floppy after vomiting or diarrhoea, seek specialist care at your closest hospital emergency department.

Solomon Star promised to ‘promote China’ in return for funding

By Bernadette Carreon and Aubrey Belford

A major daily newspaper in Solomon Islands received nearly US$140,000 in funding from the Chinese government in return for pledges to “promote the truth about China’s generosity and its true intentions to help develop” the Pacific Islands country, according to a leaked document and interviews.

The revelation comes amid Western alarm over growing Chinese influence over the strategically located country, which switched diplomatic recognition from Taiwan to China in 2019 and then signed a surprise security agreement with Beijing last year.

Solomon Islands journalists have complained of a worsening media environment, as well as what is perceived to be a growing pro-China slant from local outlets that have accepted funding from the People’s Republic.

A document obtained by OCCRP shows how one of these outlets, the Solomon Star newspaper, received Chinese assistance after providing repeated and explicit assurances that it would push messages favorable to Beijing.

Reporters obtained a July 2022 draft funding proposal from the Solomon Star to China’s embassy in Honiara in which the paper requested SBD 1,150,000 (about $137,000) for equipment, including a replacement for its aging newspaper printer and a broadcast tower for its radio station, PAOA FM.

The Solomon Star said in the proposal that decrepit equipment was causing editions to come out late and “curtailing news flow about China’s generous and lightning economic and infrastructure development in Solomon Islands.”

The document shows the Chinese embassy had initially offered SBD 350,000 in 2021, but revised this number upward in recognition of the newspaper’s needs.

A dozen pledges
In total, the proposal contains roughly a dozen separate pledges to use the Chinese-funded equipment to promote China’s “goodwill” and role as “the most generous and trusted development partner” in Solomon Islands.

In interviews, both the Solomon Star’s then-publisher, Catherine Lamani, and its chief of staff, Alfred Sasako, confirmed the paper had made the proposal, but declined to speak in detail about it.

Sasako said the newspaper maintained its independence. He said any suggestion it had a pro-Beijing bias was “a figment of the imagination of anyone who is trying to demonise China.”

Sasako said the paper had tried unsuccessfully for more than a decade to get assistance from Australia’s embassy in the country. Other Western countries, such as the United States, had neglected Solomon Islands for decades and were only now showing interest because of anxiety over Chinese influence, he added.

“My summary on the whole thing is China is a doer, others are talkers. They spend too much time talking, nothing gets done,” he said.

Press delivered
OCCRP was able to confirm that the printing equipment the Solomon Star had requested was indeed purchased and delivered earlier this year.

“I can confirm what was quoted was delivered in February and the payments came from the Solomon Star,” said Terry Mays, business development manager of G2 Systems Print Supply Division, the Brisbane, Australia, based supplier named in the proposal.

The Solomon Star funding is just one part of a regional push to get China’s message out in the Pacific Islands, as well as build relationships with the region’s elites, reporters have found.

Earlier this month, OCCRP reported on an aborted deal in the northern Pacific nation of Palau involving the publisher of the country’s oldest newspaper and a Chinese business group with links to national security institutions.

Bernadette Carreon and Aubrey Belford report for the Organised Crime and Corruption Reporting Project (OCCRP). OCCRP is funded worldwide by a variety of government and non-government donors. OCCRP’s work in the Pacific Islands is currently funded by a US-government grant that gives the donor zero say in editorial decisions.

How do you know when it’s time to seriously think about changing your child’s school?

Source: The Conversation (Au and NZ) – By Vanessa Cobham, Professor of Clinical Psychology, The University of Queensland

Going to school can be challenging for children and young people at times. Most young people will have patches during their school career where it feels hard. That’s normal. Getting through those hard times can bring with it sense of mastery, confidence and resilience.

Of course, this is not the experience of all young people, and many families find themselves asking whether a change of schools might be the best option for their child.

This is a big decision and one that parents don’t make lightly – few parents think it’s a good idea to change their child’s school on a regular basis.

While there are no black-and-white answers around this, there are some questions that might help your thinking.




Read more:
Back-to-school blues are normal, so how can you tell if it’s something more serious?


Involve the current school if you can

Sometimes, when things are very difficult for your child at school, it can be easy to forget teachers and schools – just like parents – want the best possible outcomes for the children in their care.

If you haven’t already, contact your child’s school or teacher.

The best solutions are usually reached when parents and teachers can work as a team to understand and help children who are unhappy or struggling.

Understanding why school feels like such a struggle

If a child is unhappy at school, the cause may be academic or social or a combination of both.
Liza Summer/Pexels

There are many different aspects to school. Students need to manage academic work, peer interactions as well as their own behaviour and emotions in the classroom and playground.

To figure out how best to support your child, you will need to work with them and their teacher(s) to develop a good understanding of exactly what it is about school that is hard.

Maybe they are confused in maths lessons, maybe they are having problems with their friends or maybe your child is experiencing bullying. Often it will be a combination of factors.

Anxiety is often the big emotion behind children’s struggles with school. If this is the case for your child, your child may benefit from learning about how to manage anxiety (there are evidence-based free online programs).

Another important factor to consider is the “goodness-of-fit” between your child’s strengths and abilities and the school they are attending.

Maybe you set your heart on your child attending a particular school (perhaps one that has a reputation for academic or sporting excellence). Maybe you enrolled them as soon as they were born. But is this emphasis right for your child?




Read more:
You can’t fix school refusal with ‘tough love’ but these steps might help


Are there skills or supports your child needs?

Once you’ve identified the aspect(s) of school that are presenting challenges for your child, think about whether there are skills they can be helped to develop to manage these more effectively.

This might include learning how to manage frustration when things don’t go their way, or how to respond assertively, rather than being aggressive when they are challenged,.

There might be supports that can be put in place by the school to help, such as extra learning support. Speak to your child’s teacher if you are concerned they might be being picked on and see if you can work collaboratively to address the problem.

Is changing schools going to help?

Once you feel like you understand your child’s challenges at school, it’s important to ask yourself: “how likely is it that their specific situation is going to be improved by changing schools?”

Keep in mind too the message you may be unintentionally communicating to your child by changing schools – we want to avoid reinforcing avoidance of anxiety-provoking situations that are manageable with the right support.

Also keep in mind that, apart from home, school is the place that children spend the most time. This means that it is likely that sometimes, children’s distress at school is influenced by factors that aren’t necessarily caused by school. This could include mental health issues that are not specifically related to school or worries about the family’s financial situation.

A fresh start

Sometimes, despite everyone’s best intentions and efforts, there might come a point where it’s time to acknowledge a challenging situation at school is not changing. And a child’s mental health and wellbeing is being negatively impacted. If this is the case, a fresh start at a new school may be the best option.

One way to explain it to your child could be to say something like

I believe in you. With your teachers, we’ve tried our best, but this school isn’t the best fit for you and now it’s time for a fresh start.

Leaving one school for another one doesn’t represent a failure. Rather, it represents a change in direction based on the available information.

Fiji faces more children being in trouble over ‘ice’, warns FCOSS

By Rakesh Kumar in Suva

The Fiji Council of Social Services (FCOSS) has warned that the nation needs to prepare itself to face more children being in conflict with the law.

Chief executive officer Vani Catanasiga highlighted this while responding to Attorney-General Siromi Turaga’s revelation at the Lomaiviti Provincial Council meeting last week that schoolchildren were being used to peddle the highly addictive illegal drug methamphetamine, commonly known as “ice”.

She said a concerted and coordinated approach was needed to tackle this issue.

If the issue was not resolved, there could be a drop in education attainment rates and pressure on national social services systems, she added.

Methodist Church in Fiji and Rotuma president Reverend Ili Vunisuwai said poverty was the root cause of the problem.

He said the issue was serious and the government, church and vanua should come together to solve the issue.

Wenda accuses Jakarta of crackdown in response to Papuan MSG rallies

Asia Pacific Report

Indonesia has stepped up its campaign of repression against West Papuans peacefully rallying for full membership of the Melanesian Spearhead Group (MSG), says a Papuan advocacy leader.

Benny Wenda, interim president of the United Liberation Movement for West Papua (ULMWP), said a “massive military and police presence” greeted Papuans who had taken to the streets across West Papua calling for full membership.

In Sorong, seven people were arrested — not while raising the banned Morning Star flags of independence and shouting Merdeka (“freedom”), but for holding homemade placards supporting full membership, according to Wenda.

MACFEST2023

In Jayapura and Wamena, protesters were chased by security forces, beaten and dragged away into police cars, Wenda said in a statement.

During a protest in Dogiyai, 20-year-old Yosia Keiya was alleged to have been summarily executed by Indonesian police on July 13 while he was peacefully sitting on the roadside.

“Eyewitnesses reported seeing two police cars arrive in the vicinity and shoot Keiya without provocation,” Wenda said in the statement.

“This crackdown follows the mass arrest of KNPB (West Papua National Committee) activists handing out leaflets supporting full MSG membership on July 12.

‘Ocean of violence’
“But Keiya and those arrested are only the latest victims of Indonesia’s murderous occupation — single drops in an ocean of violence West Papuans have suffered since we rose up against colonial rule in 2019.”

Both Indonesia and the ULMWP are members of the MSG – the former as an associate and the ULMWP as an observer.

The full members are Fiji, FLNKS (New Caledonia’s Kanak and Socialist National Liberation Front), Papua New Guinea, Solomon Islands and Vanuatu.

“Melanesian leaders must ask themselves: is this how one group member treats another? Is this how a friend to Melanesia treats Melanesians?” asked Wenda.

“The fact that they brought an Indonesian flag to the Melanesian Arts Festival in Port Vila, only shortly after their soldiers shot Keiya dead, is an insult.

“They’re dancing on top of our graves.”

Wenda said West Papua was entitled to campaign for full membership by virtue of Melanesian ethnicity, culture, and linguistic traditions.

“In all these respects, West Papua is undeniably Melanesian — not Indonesian,” he said.

“While Indonesia won its independence in 1945, we celebrated our own independence on December 1, 1961. Our separateness was even acknowledged by Indonesia’s first Vice-President Mohammed Hatta, who argued for West Papuan self-determination on this basis.

“More than anything, this crackdown shows how much West Papua needs full membership of the MSG.

“Right now, we are defenseless in the face of such brutal violations; only as a full member will we be able to represent ourselves and expose Indonesia’s crimes.

“West Papuans are telling the world they want full membership. By coming out onto the streets with their faces painted in the colours of all the Melanesian flags, they are saying, ‘ We want to return home to our Melanesian brothers and sisters, we want to be safe.’ It is time for Melanesian leaders to listen.”

The MACFEST 2023 — the Melanesian Arts and Culture Festival — ends in Port Vila today.

The MSG meeting to decide on full membership is due to be held soon although the dates have not yet been officially set.

Secrets wrapped in fabric: how our study of 100 decomposing piglet bodies will help solve criminal cases

Source: The Conversation (Au and NZ) – By Paola A. Magni, Senior Lecturer in Forensic Science, Murdoch University

Photo by Stevie Ziogos, Author provided

Until the late 19th century, the success of criminal investigations largely hung on witness reports and (often extorted) confessions. A lack of scientific tools meant investigators needed advanced deductive reasoning abilities – and even then they’d often hit a dead end.

Today, investigations demand an interdisciplinary and high-tech approach, involving experts from diverse scientific disciplines. Stabbing investigations are particularly important, as fatal stabbings are the leading cause of homicide in countries with restricted access to firearms, including Australia.

Carefully interpreting CCTV footage can be useful, but sometimes the crime scene won’t have surveillance cameras. The victim’s body may be discovered days, weeks, or months after the event. By then it may be partially consumed by insects – or rain may have washed away the blood stains, or potentially even the murder weapon.

In such a case, analysing damage to a victim’s clothing can provide crucial insight. But how does clothing on a decomposing body react to environmental and biological factors?

This was our question as we conducted research using the decomposing bodies of more than 100 stillborn piglets. Our findings from this first-of-its-kind experiment could help investigators solve future (and past) crimes in which stabs, tears or other damages to clothing are in question.

Pigs wrapped in fabric

Textile analysis has a significant role in forensic investigation. Clothes can preserve crucial information about the events leading up to someone’s death. Evidence might come in the form of fibres under a victim’s fingernails, tears in the clothing resulting from movement or traction, or cuts and holes caused by weapons.

However, the decomposition process itself will also alter the fabric and existing damages. It may even introduce new damages that complicate the analysis.

To understand how clothing might change throughout this process, we conducted an experiment in the summer heat of Western Australia. We used more than 100 stillborn piglets (simulating human remains) wrapped in common fabrics including cotton, stretchy synthetic material, and a fabric blend. Some piglets were left unclothed as control samples.

The experiment was conducted at a facility in Western Australia.

We intentionally inflicted cuts and tears on most of the fabrics, before leaving the carcasses to decompose naturally in a bushland environment until only bones remained. The bodies were shielded from large scavengers, but not from carrion insects.

While previous research has explored the impact of clothing on decomposition, we were focused on the other side of the coin: how do insects impact the fabric on a decomposing carcass? And in what ways could this jeopardise an investigation?

Exposed to natural elements

It wasn’t long before the fabrics started to transform due to exposure to bacteria, fungi, insects and other environmental factors.

They changed in shape and texture, and became stretched as a result of the natural bloating of the carcasses. Less than a week after the carcasses were placed, new holes appeared in the fabric – especially in cotton – as the fibres broke down.

There were also chemical changes due to potential exposure to body fluids and the chemical products of bacteria and fungi.

Experimental fabrics observed with a ‘scanning electron microscope’ (SEM) showed fungal colonisation.

Insects were particularly active in areas where body fluids were present. Of twenty insect groups collected and identified, blowflies and carrion beetles were the most common antagonists.

Throughout the 47 days of the experiment, we managed to collect a range of data on fabric degradation throughout the decomposition process. It’s the first time this has been documented in such detail in a controlled experiment.

Insects visited the bloodstains of the fabric during the early stages of the experiment.

New tools to solve new (and old) mysteries

Although textile damage analysis is vital for forensics, there has been limited research on how it overlaps with forensic entomology and taphonomy (the study of how organisms decompose). Our research shows fabrics can hold significant evidence, and this evidence changes as bodies decompose while being exposed to the environment.

There are myriad examples of crimes where evidence related to clothing has been crucial to solving the case.

In the 1980 Chamberlain case, a jury wrongly found Lindy Chamberlain and her husband Michael guilty of murdering their nine-week-old daughter Azaria, who had disappeared.

It was only when Azaria’s clothing was recovered a week after her disappearance that investigators had evidence of a dingo having snatched her (as the clothes showed signs of having been dragged through sand). The Chamberlains were exonerated as a result.

More recently, a person of interest was arrested in New York as the “Craigslist ripper”, a serial killer responsible for the murder of more than ten people. Investigators obtained DNA evidence from strands of hair found in burlap sacks used to hide and transport the bodies.

Although many details of this particular case remain undisclosed, such investigations will most likely use insect-related evidence and other trace evidence on textiles to help make important inferences, including about time of death.

More generally, our work will help investigators avoid misinterpreting evidence from clothing. For instance, if investigators aren’t aware holes in fabric can form through exposure to insects and natural elements, they might incorrectly attribute them to an animal or human attacker.

Similarly, by gauging which portion of clothing has the most insect damage, they might be able to understand where the most fluid was present on the body (if it’s found as skeletal remains). This could help them figure out where and how damage was inflicted.

This year we published guidelines to help other forensic professionals in the process of observing and collecting insects at a crime scene, and in considering how insect activity may be connected with a victim’s clothing. We hope our work can help future investigations, and maybe even reopen some cold cases.

More corrupt, fractured and ostracised: how Vladimir Putin has changed Russia in over two decades on top

Source: The Conversation (Au and NZ) – By Matthew Sussex, Fellow, Strategic and Defence Studies Centre, Australian National University

Vladimir Putin’s own version of history casts himself as modern Russia’s bulwark and champion.

According to this narrative, Putin has sturdily held back waves of foreign and domestic adversaries, and simultaneously restored Russia to greatness.

Although these breathless tales of Putin’s heroics may still resonate among Russians who’ve been spoon-fed a rich diet of disinformation for years, informed observers will view them on a spectrum ranging from embellished to the absurd.

Future historians are unlikely to treat Putin kindly. He has ruled through a combination of fear and favour, cynically upending Russia’s proto-democracy by making dissent a crime rather than a crucial part of political life. Russia has become a nation under the thrall of Putin’s singular idea, instead of a healthy contest between competing ones.

He has progressively sickened Russian society, creating a toxic culture that celebrates xenophobia, nativism and violence.

And by launching a foolish war of imperial expansion in Ukraine that his much-vaunted modernised military has proved incapable of winning, he has inadvertently revealed the fragility of his own power structure.

Putin’s ascent

Putin’s political ascent began once he took over as head of the Russian Security Council in March 1999, long seen as a likely pathway to executive leadership. He then assumed Russia’s prime ministership, and, soon after, its presidency as an increasingly infirm Boris Yeltsin sought to anoint a successor.

Putin’s willingness to protect the interests of “the family” – the network of cronies and oligarchs comprising Yeltsin’s inner circle – made him an obscure but nonetheless logical choice.

A struggle for order and stability has been a consistent leitmotif in how Putin has portrayed himself. He played up this theme during Russia’s presidential election in 2000, which followed the crippling 1998 Russian financial crisis, and was held amid Russia’s second war in Chechnya.

In his debut campaign, Putin offered little beyond a vague promise to restore order and make Russia a great power again. He faced little opposition once two leading political figures – Moscow mayor Yuri Luzhkov and former Prime Minister Yevgeny Primakov – pulled out of the race. Russians elected him with 53% of the vote, more out of a sense of relief than enthusiasm.

Upon assuming the leadership, Putin set about stabilising the economy. He amended Russia’s tax code, replacing an arcane system of loopholes and tax breaks with flat rates to boost compliance. In 2004, he effectively renationalised the oil and gas industries after the forced breakup of Yukos, which controlled around 20% of Russia’s oil production.

This sent both an economic and a political message: Russia’s future prosperity would be driven by energy revenues, and Russia’s oligarchs would only prosper at Putin’s pleasure. Such has been Russia’s reliance on energy that by 2021, taxes and dividends from oil and gas companies accounted for 45% of Russia’s federal budget.

Putin’s economic miracle?

After the September 11, 2001, attacks and subsequent US-led global war on terror, Russia’s economy rebounded considerably, aided by high energy prices.

Between 2000 and 2007, average disposable income increased considerably. Inflation fell and the economy grew by around 7% a year, although real wages declined. While the economy suffered a recession as a result of the global financial crisis in 2008, growth was swiftly restored.

Annual household income rose to an estimated US$10,000 per capita in 2013, but by 2022 had contracted to only $7,900. Hence Russians have, on average, been worse off over the last decade.

How Russia is shifting to a war economy in the face of international sanctions


This is partly due to Western sanctions imposed after the country’s annexation of Crimea in 2014. Later, following the 2022 invasion of Ukraine, Russia defaulted on its foreign currency debt (for the first time since 1918), and the economy entered recession in November.

Significant structural problems in Russia’s economy and society have persisted under Putin. Wealth is unevenly distributed, concentrated in Moscow and St. Petersburg, and in Russia’s regions it’s highly centred on local elites.

Russian life expectancy under Putin has improved only slightly. In 2021, it was estimated at 69 years, compared to 65 years in 2000.

On average, Russians have shorter lives than Iraqis (70 years), and only live marginally longer than citizens of Eritrea (67 years) and Ethiopia (65 years).

Kleptocrats, meet autocrats

Bribery and institutionalised corruption have been just as much a hallmark of Putin’s rule as his predecessor’s.

Despite fanfare about clearing out the oligarchs, Russia has scored consistently poorly on Transparency International’s Corruption Perceptions Index. In 2022, Russia was ranked 137th out of 180 nations. By comparison, after Putin had finished his first term as president in 2004, Russia placed 90th.

Putin’s rule is also the story of Russia’s slide from a “managed” democracy to an autocratic regime. This was a gradual process, justified by the need for new laws to protect society.

It began in 2003 when Russian media were barred from political analysis during elections. By 2012, Putin’s imposition of new laws that criminalised foreign agents, protests and criticism of the government saw Russia ranked 148th out of 176 countries on the Reporters Without Borders Press Freedom Index. This year, it has slipped to 164th out of 180 countries.

After the Ukraine invasion, Russians convicted of “discrediting the military” have faced jail terms, fines, beatings, social ostracism, loss of income and benefits, and even psychiatric confinement.

Putin’s legacy: ostracism and fragility

Putin’s Russia is a society in which enemies abound. With respect to perceived external adversaries – NATO members and the broader West – Putin sees regime security as being synonymous with national security. As a result, his primary fears are personal, not geopolitical.

It’s not NATO expansion that concerns Putin, but what an alliance of largely democratic nations may bring with it: the prospect of “colour revolutions”, in which populations seek to wrest control from the hands of corrupt dictators.

By invading Ukraine, Putin has actually succeeded in enlarging NATO further, with Finland and Sweden joining the alliance. He has prompted Germany and other overdependent European states to wean themselves off Russian oil and gas. And he’s ensured Russia will remain a Western pariah for the foreseeable future, while bequeathing Russia’s next generation the lasting hatred of Ukrainians.

Russia now faces an uncertain future. Instead of Putin’s vision of a Euro-Pacific great power, it seems destined to be little more than a nuclear-armed raw materials appendage of China.

Even worse for Putin, his rule now looks increasingly tenuous. His failures in Ukraine have proven impossible for Russia’s compliant state media to fashion into a story of triumph.

Putin’s response to Yevgeny Prigozhin’s dramatic mutiny in June added to the perception of weakness. It initially took him several hours to appear in an emergency broadcast, in which he spoke of a potential civil war and promised to liquidate the Wagner traitors.

But once a hasty deal with Prigozhin was struck, that strong statement was walked back only hours later by Putin’s press secretary, who was forced to paint the Wagner forces simultaneously as both heroes and enemies of the state.

The rise of Yevgeny Prigozhin: how a one-time food caterer became Vladimir Putin’s biggest threat


Later, in an address to Russian soldiers, Putin thanked the military for saving Russia, even though it hadn’t confronted the revolt.

The equally apathetic response by the general public (indeed, nobody tried to lie down in front of a Wagner tank to protect Putin) was also telling. So, too, was the fact Wagner operatives were able to escape the mutiny unpunished, while ordinary citizens face jail terms for even short silent protests.

Putin’s Russia is starting to look like Tsarist Russia: a state that collapsed under the weight of its own contradictions, as British historian Orlando Figes put it. Russia in 2023 now looks even more fractured than it did when Putin took over, ostensibly to save it from turmoil.

Perhaps the greatest irony of Putin’s near-quarter century at the helm, then, is that he has come to personify the chaos he has long professed to abhor.

Renaming obesity won’t fix weight stigma overnight. Here’s what we really need to do

The stigma that surrounds people living in larger bodies is pervasive and deeply affects the people it’s directed at. It’s been described as one of the last acceptable forms of discrimination.

Some researchers think the term “obesity” itself is part of the problem, and are calling for a name change to reduce stigma. They’re proposing “adipose-based chronic disease” instead.

We study the stigma that surrounds obesity – around the time of pregnancy, among health professionals and health students, and in public health more widely. Here’s what’s really needed to reduce weight stigma.

Weight stigma is common

Up to 42% of adults living in larger bodies experience weight stigma. This is when others have negative beliefs, attitudes, assumptions and judgements towards them, unfairly viewing them as lazy, and lacking in willpower or self-discipline.

People in larger bodies experience discrimination in many areas, including in the workplace, intimate and family relationships, education, health care and the media.

Weight stigma is associated with harms including increased cortisol levels (the main stress hormone in the body), negative body image, increased weight gain, and poor mental health. It leads to decreased uptake of, and quality of, health care.

Weight stigma may even pose a greater threat to someone’s health than increasing body size.

Should we rename obesity?

Calls to remove or rename health conditions or identifications to reduce stigma are not new. For example, in the 1950s homosexuality was classed as a “sociopathic personality disturbance”. Following many years of protests and activism, the term and condition were removed from the globally recognised classification of mental health disorders.

In recent weeks, European researchers have renamed non-alcoholic fatty liver disease “metabolic dysfunction-associated steatotic liver disease”. This occurred after up to 66% of health-care professionals surveyed felt the terms “non-alcoholic” and “fatty” to be stigmatising.

Perhaps it is finally time to follow suit and rename obesity. But is “adiposity-based chronic disease” the answer?

Changing the terminology to ‘people with obesity’ won’t reduce stigma against fat people


A new name needs to go beyond BMI

There are two common ways people view obesity.

First, most people use the term for people with a body-mass index (BMI) of 30kg/m² or above. Most, if not all, public health organisations also use BMI to categorise obesity and make assumptions about health.

However, BMI alone is not enough to accurately summarise someone’s health. It does not account for muscle mass and does not provide information about the distribution of body weight or adipose tissue (body fat). A high BMI can occur without biological indicators of poor health.

Second, obesity is sometimes used to describe the condition of excess weight when mainly accompanied by metabolic abnormalities.

To simplify, this reflects how the body has adapted to the environment in a way that makes it more susceptible to health risks, with excess weight a by-product of this.

Renaming obesity “adiposity-based chronic disease” acknowledges the chronic metabolic dysfunction associated with what we currently term obesity. It also avoids labelling people purely on body size.




Read more:
Using BMI to measure your health is nonsense. Here’s why


Is obesity a disease anyway?

“Adiposity-based chronic disease” is an acknowledgement of a disease state. Yet there is still no universal consensus on whether obesity is a disease. Nor is there clear agreement on the definition of “disease”.

People who take a biological-dysfunction approach to disease argue dysfunction occurs when physiological or psychological systems don’t do what they’re supposed to.

By this definition, obesity may not be classified as a disease until after harm from the additional weight occurs. That’s because the excess weight itself may not initially be harmful.

Even if we do categorise obesity as a disease, there may still be value in renaming it.

Renaming obesity may improve public understanding that while obesity is often associated with an increase in BMI, the increased BMI itself is not the disease. This change could move the focus from obesity and body size, to a more nuanced understanding and discussion of the biological, environmental, and lifestyle factors associated with it.




Read more:
When you’re sick, the support you’ll get may depend on the ‘worth’ of your disease


Workshopping alternatives

Before deciding to rename obesity, we need discussions between obesity and stigma experts, health-care professionals, members of the public, and crucially, people living with obesity.

Such discussions can ensure robust evidence informs any future decisions, and proposed new terms are not also stigmatising.

People living with obesity need to have a say in any future terms for it.

Today’s disease names are less catchy, but also less likely to cause stigma


What else can we do?

Even then, renaming obesity may not be enough to reduce the stigma.

Our constant exposure to the socially-defined and acceptable idealisation of smaller bodies (the “thin ideal”) and the pervasiveness of weight stigma means this stigma is deeply ingrained at a societal level.

Perhaps true reductions in obesity stigma may only come from a societal shift – away from the focus of the “thin ideal” to one that acknowledges health and wellbeing can occur at a range of body sizes.

The secret lives of silky sharks: unveiling their whereabouts supports their protection

Source: The Conversation (Au and NZ) – By Shona Murray, PhD candidate, The University of Western Australia

Marine Futures Lab, Author provided

Open ocean sharks are elusive and mysterious. They undertake vast journeys that span hundreds to thousands of kilometres across immense ocean basins. We know very little about the secret lives of ocean sharks, where they live and why they are there.

What we do know is sharks are immensely important to the natural systems in which they live. Over 450 million years of evolution have perfected their role as apex predators and they play vital roles in fish community regulation and nutrient cycling. Healthy ecosystems rely on healthy shark populations.

Sharks, numbering more than 500 species, are also among the most threatened groups of vertebrates (animals with backbones). After surviving five mass extinctions through geological time, sharks are now facing the greatest threat to their survival from industrial fishing.

Their elusive nature and the immensity of our oceans means sharks are difficult to study. Our limited knowledge is particularly problematic given their threatened status. A solid understanding of the distribution of oceanic sharks is fundamental to their protection and our new research provides valuable insights into the secret lives of these wide-ranging predators.

Silky by name, silky by nature

Silky sharks (Carcharhinus falciformis), named for the silky-smooth feel of their skin, are emblematic of open ocean sharks. They are highly mobile, have long life-spans, and are slow to reproduce. They are found throughout tropical and sub-tropical waters.

Silky shark numbers have declined globally due to industrial-scale fishing. Targeted for their fins and meat, they are also frequently incidentally caught in tuna fisheries. In 2017 the International Union for the Conservation of Nature classified this species as vulnerable to extinction. Their trade is controlled under the Convention on International Trade in Endangered Species.

What we did

Baited remote underwater video systems, or BRUVS for short, are used to document the wildlife of the open oceans. Armed with a pair of small action cameras and baited to attract predators, BRUVS are suspended at 10m depth and drift with ocean currents. Video analysts review the footage to identify, count and measure all observed animals.

BRUVS have previously revealed the impact of human activity on marine predator populations, the ecological value of offshore oil and gas platforms as novel ecosystems, and even that tunas use sharks to scratch their itches.

We deployed more than 1,000 BRUVS across the Atlantic, Pacific and Indian oceans between 2012-20 to record where silky sharks hang out and predict how many there are and how big they are.

A love affair between silky sharks and seamounts

Silky sharks love seamounts. The closer we sampled to seamounts, the more frequently we observed silky sharks, and in higher numbers.

Seamounts are huge underwater mountains that rise from depths of thousands of metres to pinnacles that summit from hundreds to just tens of metres below the surface. The best estimate predicts the occurrence of more than 37,000 seamounts worldwide.

There are more than 37,000 seamounts globally and the majority are unprotected.
Data from Yesson et al. (2019)

Seamounts are often hotspots of marine biodiversity. They act as landmarks in the otherwise relatively featureless open ocean seascape. Seamounts provide feeding, breeding, and resting spots for ocean roamers such as sharks, tuna, and whales. Migratory wildlife also use seamounts as navigational beacons and as stepping stones along their trans-ocean journeys.

Our results also reveal the smallest silky sharks hang out closest to seamounts. Seamounts may provide a rich smorgasbord for these rapidly growing youngsters.

A human footprint on silky sharks

Humans are leaving their heavy footprints on much of the ocean and silky sharks are no exception. Silky shark numbers declined the closer we sampled to coastal ports. Only the most remote areas had high numbers of silky sharks.

Silky sharks close to ports and human populations were also smaller than those observed further away. Such patterns are consistent with fishing impacts as exploitation typically first removes the largest individuals from the population. Our results reflect those for other open ocean sharks: hammerhead, sandbar, tiger and whale sharks have all declined globally in numbers and size .

The distribution of silky sharks exemplifies the pervasive and negative impacts of human activity on oceanic sharks more generally. It highlights the critical need for refuges in which these animals are protected from exploitation.

A path to protection

The need for improved protection for oceanic wildlife is well-recognised and marine protected areas are a key tool to deliver this protection. In 2022, under the Convention on Biological Diversity, nearly every country in the world committed to protect 30% of their oceans by 2030.

In 2023, the High Seas Treaty was ratified by the 193 member states of the United Nations, paving the path towards strong and effective protection of the vast swaths of ocean beyond national jurisdiction. Given that less than 2.9% of our oceans are currently highly protected, such opportunities are essential.

Our research provides clues on how best to harness these agreements to protect silky sharks and their open-ocean companions. If marine protected areas are going to work, they need to include areas that threatened wildlife inhabit. As seamounts are hotspots for silky sharks, they are a fitting focus for marine protected areas.

It has never been more important to protect sharks. We have never had as much knowledge to do so. We hope recent commitments to ocean protection will spur research to further unveil the secret lives of oceanic sharks and ensure their survival in the face of their greatest threat yet.

How do you know when it’s time to think seriously think about changing your child’s school?

Source: The Conversation (Au and NZ) – By Vanessa Cobham, Professor of Clinical Psychology, The University of Queensland

Going to school can be challenging for children and young people at times. Most young people will have patches during their school career where it feels hard. That’s normal. Getting through those hard times can bring with it sense of mastery, confidence and resilience.

Of course, this is not the experience of all young people, and many families find themselves asking whether a change of schools might be the best option for their child.

This is a big decision and one that parents don’t make lightly – few parents think it’s a good idea to change their child’s school on a regular basis.

While there are no black-and-white answers around this, there are some questions that might help your thinking.

Back-to-school blues are normal, so how can you tell if it’s something more serious?


Involve the current school if you can

Sometimes, when things are very difficult for your child at school, it can be easy to forget teachers and schools – just like parents – want the best possible outcomes for the children in their care.

If you haven’t already, contact your child’s school or teacher.

The best solutions are usually reached when parents and teachers can work as a team to understand and help children who are unhappy or struggling.

Understanding why school feels like such a struggle

Liza Summer/Pexels

There are many different aspects to school. Students need to manage academic work, peer interactions as well as their own behaviour and emotions in the classroom and playground.

To figure out how best to support your child, you will need to work with them and their teacher(s) to develop a good understanding of exactly what it is about school that is hard.

Maybe they are confused in maths lessons, maybe they are having problems with their friends or maybe your child is experiencing bullying. Often it will be a combination of factors.

Anxiety is often the big emotion behind children’s struggles with school. If this is the case for your child, your child may benefit from learning about how to manage anxiety (there are evidence-based free online programs).

Another important factor to consider is the “goodness-of-fit” between your child’s strengths and abilities and the school they are attending.

Maybe you set your heart on your child attending a particular school (perhaps one that has a reputation for academic or sporting excellence). Maybe you enrolled them as soon as they were born. But is this emphasis right for your child?




Read more:
You can’t fix school refusal with ‘tough love’ but these steps might help


Are there skills or supports your child needs?

Once you’ve identified the aspect(s) of school that are presenting challenges for your child, think about whether there are skills they can be helped to develop to manage these more effectively.

This might include learning how to manage frustration when things don’t go their way, or how to respond assertively, rather than being aggressive when they are challenged,.

There might be supports that can be put in place by the school to help, such as extra learning support. Speak to your child’s teacher if you are concerned they might be being picked on and see if you can work collaboratively to address the problem.

Is changing schools going to help?

Once you feel like you understand your child’s challenges at school, it’s important to ask yourself: “how likely is it that their specific situation is going to be improved by changing schools?”

Keep in mind too the message you may be unintentionally communicating to your child by changing schools – we want to avoid reinforcing avoidance of anxiety-provoking situations that are manageable with the right support.

Also keep in mind that, apart from home, school is the place that children spend the most time. This means that it is likely that sometimes, children’s distress at school is influenced by factors that aren’t necessarily caused by school. This could include mental health issues that are not specifically related to school or worries about the family’s financial situation.

A fresh start

Sometimes, despite everyone’s best intentions and efforts, there might come a point where it’s time to acknowledge a challenging situation at school is not changing. And a child’s mental health and wellbeing is being negatively impacted. If this is the case, a fresh start at a new school may be the best option.

One way to explain it to your child could be to say something like

I believe in you. With your teachers, we’ve tried our best, but this school isn’t the best fit for you and now it’s time for a fresh start.

Leaving one school for another one doesn’t represent a failure. Rather, it represents a change in direction based on the available information.

We need more than a definition change to fix Australia’s culture of permanent ‘casual’ work

Source: The Conversation (Au and NZ) – By David Peetz, Laurie Carmichael Distinguished Research Fellow at the Centre for Future Work, and Professor Emeritus, Griffith Business School, Griffith University

The surprising thing about the Albanese government’s announced reforms to
“casual” employment is not that they’re happening. It’s that employer advocates are getting so excited about them, despite the small number of people they will affect and the small impact they will have.

That’s not to say the changes aren’t needed. Rather, true reform of the “casual” employment system, of which this is just a first but important step, has a lot further to go to resolve the “casual problem”.




Read more:
Albanese government to make it easier for casuals to become permanent employees


What is the ‘casual problem’?

This problem is that most “casual” workers aren’t really casual at all — as shown by analysis that I and colleague Robyn May did, using unpublished data from the Australian Bureau of Statistics (ABS).

The premise for hiring them is that the work is intermittent, short-term and unpredictable. But, as you can see from the chart, the last time the ABS collected these data, a majority of “casuals” worked regular hours.



Almost 60% of “casuals” had been in the job for more than a year. About 80% expected to still be there in a year’s time.

Only 6% of “casuals” (1.5% of employees) who worked varying hours (or were on standby) had been with their employer for a short time, and expected to be there for a short time.

Even now, some “casuals” have been doing the same “casual” work for over 20 years.

Permanent ‘casuals’

All this has led to a class of “permanent casuals” – a nonsense term. They should more accurately be called “permanently insecure”.

The one thing “casuals” have in common is they’re not entitled to sick leave or annual leave, and they are in a precarious employment situation. Their contract of employment only lasts till the end of their work day.

That means they have much less power than other workers. So little power, in fact, that barely half of them even get the casual loading they are meant to be paid in compensation for not receiving other entitlements.

On average, low-paid “casuals” get less pay than equivalent permanent workers, despite the loading.



Changing legal definitions

Not many “casuals” have been brave enough to challenge this exploitative relationship. But when they did a few years ago, Australia’s courts agreed permanent casual work was nonsensical.

To be a “casual worker”, there had to be no promise of ongoing employment. A court would judge this not just by what was in the formal contract of employment but also by what the employer actually did. If they kept hiring you, week after week, on a predictable roster, you weren’t casual.

In 2018, mine worker Paul Skene challenged his classification as a casual worker, arguing he had done pretty much the same work, with a few changes along the way, for five years.

The Federal Court agreed he wasn’t a casual employee and should be back-paid annual leave. Another mine worker, Robert Rossato, had a similar victory in 2020.

Employer organisations were “outraged” by the “billions” in back pay they could be forced to pay for having misclassified ongoing workers as casuals. They lobbied the Morrison government to amend the law, and challenged the rulings in the High Court.

The Morrison government changed the law in early 2021, to give primacy to the written contract, ignore employer behaviour, and protect employers from back-pay claims.

Later that year the High Court overturned the Federal Court decisions, ruling it was the written employment contract that mattered. If that was worded a certain way, you couldn’t test whether a worker was “casual” by whether the employer treated them that way afterwards.

Labor promised to overturn these interpretations, and that’s what this proposal does.




Read more:
Employers will resist, but the changes for casual workers are about accepting reality


What will the legislation change?

The details of the government’s plan is still not clear, but it is likely it will seek to amend the Fair Work Act to revert to something close to the pre-2020 definition of casual work, with a procedural twist.

It will again be possible to judge whether an employee is “casual” based on employer behaviour. And an employee who repeatedly works a similar roster can, after six months, demand “permanency” – meaning rights to sick leave, annual leave, and better protection against arbitrary sacking.

The twist: until they demanded “permanency” they won’t be entitled to any leave. So employers will be protected against claims for back pay.

Theoretically this could affect hundreds of thousands of “casual” workers. In reality, it will likely help far fewer.



Suppose you’re a “casual” labour hire worker in mining. You can tell what time you’ll start work on the first Friday next June. You go to your employer — the labour hire company — and say: “Make me permanent.” The labour hire company says: “We can’t. You might not have a job tomorrow.”

And indeed, now that you’ve asked, maybe you won’t have a job. So would you really ask?

It will depend critically on the protections offered to workers who ask to convert, and how credible they are to workers.

Most people only expect a few people to make the demand. Workplace relations minister Tony Burke says he believes only a “very small proportion” of “casuals” working regular shifts will do so.

Part of that reluctance will be fear of the consequences, and part of it will be that many casuals rely on their casual loading. About half of “casuals” are on the award minimum rate, compared with 15% of “permanent” full-time workers. Most cannot afford to “choose” to trade the money for holidays and other entitlements.

If you’re not getting the casual loading, you’ve got nothing to lose — except your job. If the power imbalance means you don’t get the loading, you won’t fancy your chances.

So, it will just work for a small number or workers – though it’s likely to be very important to them.

More needs to be done

In short, this is a good step but more needs to be done.

In most other wealthy countries all workers – including temporary workers – are entitled to annual leave. That’s not the case in Australia, because of the “casual” ruse. These laws will not change that.

There should be a universal leave entitlements. Sure, there needs to be a loading where work is unpredictable, and hence so short-term that leave entitlements would not be practical.

But everyone else should get annual and sick leave, and minimum award wages should be high enough that low-wage workers don’t have to rely on the casual loading to get by.

The challenge should be about how we transition to that situation.

US Moves to Curtail China’s Economic Investment in the Caribbean

From Toronto, Ontario

On March 8, 2023, General Laura J. Richardson of the United States (U.S.) Southern Command gave testimony at a congressional hearing wherein she issued a warning to U.S. lawmakers about the expansion of Chinese influence in the Caribbean that were at odds with purported U.S. interests in the region.[1] Richardson advised policy makers in the U.S. to “pay more attention” to the Caribbean (and Central and South America) because “proximity matters.”[2] To raise the issue to a level of “threat” for U.S. policymakers, Richardson claimed that China had “increased its support for anti-U.S. regimes in the region” of which the usual suspects Venezuela, Cuba, and Nicaragua were mentioned.[3]

Although China’s investment and trade with Venezuela, Cuba, and Nicaragua are minimal in comparison to other states in the region,[4] General Richardson expresses an urgent need for U.S. reengagement with the Caribbean region – where historically this sort of engagement by the U.S. was only used to counter “threats” like communism, socialism, Black Power, and any expression of anti-imperialism. These left leaning movements challenge U.S. interests in maintaining a global capitalist system that supports liberal theories of development via free-trade, open-markets, and privatization, for the states in its “backyard.” Washington considers growing Chinese economic ties in the region at odds with U.S. interests.

Three months after Richardson’s testimony, U.S. Vice President Kamala Harris made an official visit to The Bahamas to co-host a US-Caribbean Leaders Meeting with Bahamian Prime Minister Philip Davis. Notably, it was the first time that a high-ranking U.S. official had visited The Bahamas since it gained independence in 1973.[5] During the meeting, VP Harris stated that given “longstanding requests from Caribbean partners,” the Biden-Harris administration would be expanding U.S. diplomatic presence in the Eastern Caribbean region by opening two new embassies.[6] However, this enhanced U.S. diplomatic presence in the Caribbean belies an earlier claim made by U.S. officials in 2018 that “the cost of establishing a United States Embassy in Antigua and Barbuda or any other member state of the Organization of Eastern Caribbean States (OECS) would be prohibitive.”[7]

Reframing U.S. and its Allies’ Security Interests in the Caribbean as “Diplomatic”

The U.S. (and its allies like Canada) are pursuing a strategy of “boosting a diplomatic presence” in the Pacific and the Caribbean, to both counter and undermine China’s investments and influence with states in these areas.[8] The geostrategic importance of these (maritime) regions for the U.S. and its allies gained increased urgency given the Memorandum of Understanding (MoU) between China and the Solomon Islands in 2022,[9] and a cooperation agreement between China and Cuba signed earlier this year,[10] followed by subsequent unfounded speculation about China “spying” from a base location in Cuba.[11] As it stands right now, the U.S. has a diplomatic presence in two out of the seven countries in the Eastern Caribbean. This means that realistically there are only five states where the two embassies can be built. Those are: Antigua and Barbuda, Dominica, Montserrat, St. Kitts and Nevis, and St. Lucia.

Antigua and Barbuda have aggressively made the case for a US embassy to be housed in their country for a number of years, and given the announcement, they have ramped up those efforts. There was previously a U.S. embassy in Antigua before it closed in 1994, and of OECS countries today, Antigua has the most approved visas (and highest visa burden) to the US of OECS states. Antiguan Chief of Staff in the Prime Minister’s Office, Lionel Hurst, has also revealed in July of this year that Antigua has designated a plot of land for use by the U.S. government in case the island is chosen for an embassy.[12] However, to the chagrin of the Antiguan government, U.S. officials have yet to announce which two countries will be selected to host the embassies, even as a reception was hosted by the U.S. Embassy on Jumby Bay Island to celebrate independence.[13] While Antigua wants visa issuing streamlined for its citizens, an increased U.S. diplomatic presence in the formerly neglected Eastern Caribbean would not be aimed at alleviating visa burdens or addressing long standing requests from the region, but rather at countering China’s inroads in the region.

The U.S. is also not alone in trying to counter China’s influence in the region. U.S. Western allies in Europe are also renewing their engagement with states in the region, having hosted the third EU-CELAC summit after eight years on July 18th and 19th. At the summit, the “long-standing partnership” and “shared values and interests” were reaffirmed with the ultimate goals being transnational policing and multilateral security.[14] Canada has also made the effort to specifically reach out to Eastern Caribbean states that could house U.S. embassies, again with the aim of making bilateral and multilateral collaborations closer.[15] Given where Canada’s engagement has been, Antigua, St. Lucia, and Dominica are all strategically positioned to house one of the two U.S. embassies being planned for the region. Canadian officials have visited both Antigua[16] and St. Lucia[17] quite recently to discuss closer collaboration and bilateral relations – and all three countries recently became part of Canada’s visa-free travel program.[18]

Since the mid-1990s, given declining U.S. interest in its “backyard,” Canada has assumed the role of enforcing and maintaining positions that are in sync with Western capital and security objectives. Thus, in 2004, Canada not only planned the coup d’état which took place in Haiti against its democratically elected left-leader, but also helped to facilitate the entrance of U.S. troops there.[19] Canada also has an Operation Support Hub for the Latin America and Caribbean region (OSH-LAC) stationed in Jamaica that conducts military exercises and operations in the region alongside U.S. military forces and Jamaican Defence Forces (JDF).[20] These military exercises are also framed within the language of transnational cooperation while advancing purely security aims.

Antigua,[21] St. Lucia,[22] and Dominica[23] are strategically situated islands near maritime transport lanes, the former two of which the U.S. has previously used from the early 1940s to the early 1990s to project a military presence in.[24] Given the formation of a paternalistic army in Domnica subservient to its conservative politics, Dominica has a history of “loaning out” its bases, and officers, for U.S. (and other European) uses and training.[25] If you were to look at a map of the Eastern Caribbean countries, a U.S. embassy in both Antigua and either St. Lucia or Dominica covers proximal grounds to the other three Eastern Caribbean countries where the U.S. has no presence. Additionally, (and historically) the conservative nature of governance in OECS states like Antigua, St. Lucia, and Dominica often saw these countries’ governments support reactionary U.S. foreign policy towards countries like Haiti and Grenada. This history will undoubtedly come into consideration when the U.S. decides on the next locations of its two embassies in the area – just as Canada’s decision to have Jamaica host OSH-LAC considered Canada’s longtime security ties, with the JDF conducting espionage on its leftist Caribbean and South American neighbors.[26]

The current location of expected U.S. embassies is important for a number of reasons, foremost amongst them being the geographic location of the Eastern Caribbean. The Eastern Caribbean lies off of the coast of South America – where states like Venezuela are frequent targets of U.S. intervention, and where Guyana has recently had a massive amount of crude oil being extracted by Exxon. According to Goldman Sachs, Guyana is a “geopolitical swing state” that “offers the U.S. an alternative to Venezuela” in Latin America.[27] And just as in the case of Venezuela, the U.S. and Canada seek to curtail “Chinese influence” in Guyana.[28] For this reason U.S. politicians have recently made state visits to Guyana, attention which this country has not received since its independence in the late 1960s.[29] While it is known that states like Haiti and Cuba are frequent Caribbean targets of intervention by the U.S. and its allies – the current “diplomatic” buildup in the Eastern Caribbean should also be given attention.

Unlike Haiti and Cuba which are surrounded by a Western “diplomatic” presence that facilitates intervention, that is not the case for the Eastern Caribbean which, if brought into a similar security orbit as countries like Jamaica, can be swayed to agree to intervention in the Caribbean and in South America. As a bloc, an important goal of the OECS is to coordinate foreign policies, wherein these Eastern Caribbean states meet yearly to “harmonize the[ir] strategy in foreign policy” given their individual size.[30] This point is not to belie the general re-engagement of the U.S. and its allies in the Caribbean region as a whole. For instance, it is still the case that Haitians are protesting against foreign intervention in their country,[31] and the U.S. is also doing upgrades to its embassy in Cuba after years of neglect.[32]

History Matters: How U.S. Embassies in the Caribbean Help U.S. Security

As has been disclosed, the U.S. embassy in Antigua closed in 1994 “because of the strategic insignificance of [the Eastern Caribbean]” and “to shift resources to Eastern Europe and the former Soviet Union” (Griffith 1996, p. 25).[33] As such, it comes to no surprise that the U.S. has long considered the value of the Caribbean in purely strategic terms as it regards competition with other “powers.” In fact, “it took congressional pressure, especially from the Black Caucus, to reverse the decision on [closing] Grenada[‘s]” embassy (Griffith 1996, p. 25), given the U.S. invasion a decade prior following internal turmoil of the Grenadian Revolution.[34] Prior to 1994, Washington deployed a diplomatic and military presence in these countries to counter Marxist, communist, and potential revolutionary left movements in the Eastern Caribbean states. Most notably, repressing revolutionary fervor helped in the creation of the OECS during Ronald Reagan’s tenure as U.S. President and continued under Bill Clinton’s presidency.[35]

Increased globalization via the proliferation of neoliberal policies and structural adjustment in the Caribbean during the late 1980s and into the 1990s, meant that U.S. security interests in the Caribbean no longer needed to be diplomatically supported, as economies in the Caribbean opened, privatized, and became debt burdened – otherwise, dependent. Propaganda tactics that U.S. embassies helped to proliferate became less necessary as the “threat of communism” declined in its “backyard.” Also, in the Eastern Caribbean, the recession in the 1980s and the end of the Cold War marked an official deprioritization of the area in US geostrategy; especially due to successful interventions against, and/or failures of, revolutionary and left-reformist groups and governments in that area. The interests that did remain were largely in the security realm regarding narcotics, border patrolling, military and police training, as well as technology and equipment testing and upgrades.

Typically, a U.S. embassy “has officials to gather information and perform “liaisons” on political, economic, commercial, military, scientific, intelligence, financial, maritime, labor, agricultural, aviation, law enforcement, tax, educational, cartographic, geodesic, and geological matters”[36] (Schmitz 1995). This kind of information became unimportant to collect in the Caribbean, when the region became successfully integrated into the U.S. preferred liberal regime of political and market governance. The effects of this lack of data have been noted, as it is partly one of the reasons why general data gathering on Caribbean states is difficult. Instead, security assistance became the preferred method of engagement with the Caribbean – with “security threats” mostly involving external mandates regarding immigration, general policing, drugs, and surveillance for “antiterrorism.”[37]

Renewed interest on the part of the U.S. to open new embassies in the Eastern Caribbean region means that the U.S. security state and U.S. policy makers perceive Chinese investments as a threat – thus, we should expect these two new embassies to have a broader security purpose. The People’s Republic of China (PRC) and its ruling Communist Party invoke this history of the U.S. “fighting communism.” More accurately, the U.S. was fighting democratically elected left-governments and movements in the Caribbean region during these states’ national liberation movements and after they achieved independence during the “Cold” War. It is quite logical to surmise that increased economic investments by the PRC which fund big infrastructure projects in the region worry U.S. policy makers. PRC investments are often compared to Caribbean states’ decades-long integration into the liberal regime, which has not alleviated poverty, unemployment, inequality, or environmental destruction in the region.

Influence is only gained where it makes sense, and PRC investments that provide infrastructural, developmental, and economic assistance stand in stark contrast to the preferred Western strategies of aid with strings attached, which indebts Caribbean states, privatizes Caribbean economies, and continues to ignore Caribbean calls for reparations. Increased U.S.“diplomatic” presence in the Caribbean, in response to economic investments made by the PRC, reminds us that “states are not equally free to act across the globe,” and that the existence of spheres of influence are more accurately described as geostrategic security zones for extending the influence of states..[38] That the U.S. plans to increase its diplomatic presence in the Caribbean now should be understood as another ploy of external subversion – which exploits Caribbean people’s needs (i.e. the ability to to process visas) – to advance U.S. geostrategic aims vis-a-vis the PRC.

Mediawatch: Kiri Allan’s resignation sparks another ‘on principle’ at RNZ

By Colin Peacock, RNZ Mediawatch presenter

A board member at RNZ appointed less than a month ago quit this week after making public comments on former Justice Minister Kiri Allan’s downfall and criticising media coverage of it.

RNZ had asked Jason Ake to stop and the government said he breached official obligations of neutrality, but he was unrepentant.

Jason Ake (Ngāti Ranginui) was one of the appointments last month to the boards of RNZ and TVNZ that represented “an exciting new era for our public broadcasters as they continue to tackle the challenges of … serving all people of Aotearoa now and into the future,” according to Broadcasting Minister Willie Jackson.

“Looking forward to the mahi ahead,” Ake told his LinkedIn followers at the time.

“Hoping to bring an indigenous perspective to the strategic direction at the public broadcasting institution,” he added, honouring the advocacy of pioneers Whai Ngata, Derek Fox and Henare Te Ua “for a much more visible Māori perspective in RNZ’s strategic direction”.

But even before he could be inducted into RNZ or attend a single board meeting, Ake resigned this week in the wake of controversy over social media comments he made about the downfall of cabinet minister Kiri Allan.

“When there’s blood in the water the sharks circle, and they’re more than happy to digest every last morsel and watch the bones sink to the depth. It’s a bloodsport,” he said in a Facebook post.

Referenced mental breakdown
He also referenced former National Party leader Todd Muller, who recovered from a mental breakdown to resume his work as an MP.

Jackson told reporters in Parliament on Tuesday Ake had “often been quite vocal about issues and he’s gonna have to stop”.

RNZ chair Dr Jim Mather had already been in touch to remind Jason Ake of his responsibilities under the Public Service Commission’s code of conduct for crown entity board members.

“When acting in our private capacity, we avoid any political activity that could jeopardise our ability to perform our role, or which could erode the public’s trust in the entity,” the code says.

Ake’s initial Facebook comment was not explicitly or aggressively politically partisan. Most of the comments could be construed as a reflection on the media as much as on politics or politicians.

But there is heightened sensitivity these days because of Te Whatu Ora chair Rob Campbell, who was sacked after publicly criticising opposition parties’ health policies recently. (That was amplified when media commentaries of other government-appointed board members were scrutinised in the wake of that).

In a statement earlier this week, RNZ’s chair acknowledged that  Ake was “new to the board of RNZ”.

Communications professional
But he is also a former journalist and a communications professional who is currently Waikato Tainui’s communications manager. Along with his partner — Māori communications consultant Deborah Jensen — he is a director of a consultancy called Native Voice.

RNZ said no further comment would be made until Dr Mather and Ake had discussed the matter further.

But Ake did not wait for that.

He went on Facebook again insisting mental health was a topic that needed to be talked about, particularly because it affected Māori so much.

He also referred to “an ideological premise that we as Māori must conform”.

And while he thanked some journalists for “getting the key message”, he repeated his criticisms of the media.

“21 Māori journos got it — more than the entire compliment [sic] of our two major media entities in Aotearoa, who between them have more than 700 reporters on the staff.”

Unable to ‘stay quiet’
After that, Ake told The New Zealand Herald he had resigned from the RNZ board “on principle”, because he would have been unable to stay quiet about broadcasting decisions which impacted on Māori.

“Crown entity governance has its own tikanga and protocols that need to be observed,” Dr Mather said in a statement describing it as “a missed opportunity.”

That was reinforced by Deputy Prime Minister Carmel Sepuloni.

“It’s really important that they seem to be impartial and they’re not getting involved in the politics in any way. They’ve got really important roles to play and so the public needs to have faith in them being impartial,” she told TVNZ’s Te Karere.

Whanua Ora Minister Peeni Henare told Te Karere that crown entity board members “must represent all of Aotearoa”.

Rob Campbell wrote a piece for The New Zealand Herald the same day, applauding Ake for in his words, “having the guts to speak his truth”.

“They should not remove people, or put pressure on people to resign while in a position because the public views are not mutually shared or inconvenient. Nor should they be censored or silenced. They can appoint new directors when their term has served,” he said.

Obliged to be ‘politically noisy’
In a piece for the Herald explaining his own decision, Ake said that membership of Te Whakaruruhau o Nga Reo Irirangi o Aotearoa, the umbrella group representing more than 20 iwi radio stations around the country, obliged him to be “politically noisy”.

“This would have placed me on a collision course with the political neutrality expectations as set out in the Crown Entities guidelines,” he wrote.

“I made it clear that I came with a deep commitment to the Treaty and ensuring that it is embedded into the fabric and culture of the organisation. The Treaty is by definition a political pact and this required uncomfortable and sometimes public conversations,” Ake wrote in The Herald.

My presence cannot be a distraction to the transformative mahi ahead of it. It would not be fair on the chair or the other board members and it will undoubtedly stymie progress for the entire organisation,” he added.

But commenting on mental health or broadcasting would not be a problem if he refrained from criticising political decisions or individual politicians, or discussing RNZ in public.

Jackson also appointed Ake to lead the Māori Media Sector Shift review back in 2020.

While in that role, Ake aired opinions on broadcasting broadly mirroring Jackson’s own aspirations for state-owned media.

Boost for Māori creators
“Where is the allowance for decent Māori stories? We’ve got an opinion and a view under a whole range of things that’s not reflected in the television in high rating programmes. It shouldn’t ghetto-ised into digital online platforms only,” Ake told Radio Waatea in 2021.

In another Radio Waatea interview, Ake said RNZ and TVNZ’s merger must be a boost for Māori content creators.

“The human capability and capacity out there is really, really limited. And it doesn’t make sense for the Māori sector to fight with itself in order to bring to the market good content. I think that’s where the merger ought to look for what a decent template would look like,” he said.

Ake also aired concerns about the commercial media organisations getting money from the Public Interest Journalism Fund for Māori journalism, content and topics.

“Why would you put yourself in front of an environment that’s diabolically opposed or structured in a way that doesn’t recognise the value that Māori bring to the discussion?

“The internal culture at some of these organisations is so ingrained that it has become part of the carpets, the curtains and everything else. So there needs to be systemic change inside these commercial organisations,” he argued.

Content funding increased
Māori broadcasting content funding was boosted by $82 million in the past two years, as part of the review which Jackson appointed Ake to oversee.

In the wake of the merger’s collapse, RNZ’s own funding has been boosted — in part to fuel the Rautaki Māori (Māori strategy) Jackson called for in the past and now supports.

Ake has rejected a governance role at RNZ at a time when his input and influence may have had its greatest effect.

He has not responded so far to Mediawatch’s calls and messages.

But his most recent post on LinkedIn announcing his resignation has this footnote for reporters: “Stop ringing me. I have mahi to do.”

‘No more coups’, Fiji’s navy commander tells nation

By Arieta Vakasukawaqa in Suva

“The people of Fiji don’t deserve to go through another coup.”

This was the view shared by Fiji Navy commander Captain Humphrey Tawake while speaking to The Fiji Times during the Fiji Navy Day celebrations at Stanley Brown Naval Base in Walu Bay, Suva, this week.

“Fiji, as a nation doesn’t need another coup,” said Tawake, who is also deputy RFMF commander of the Republic of Fiji Military Forces (RFMF).

“The RFMF commander has made his stance and we will abide by that.

“We will abide by the rule of law, there will be no more coups.

“We will respect the democratic process that has taken place and we must be mindful that we all have a role to play.”

Captain Tawake said at the event on Thursday that people or institutions should stop using the RFMF for their personal or political agenda.

‘Steadfast’ over rule of law
“RFMF is a professional institution and we stand steadfast to the rule of law and democracy.

“I stand by the RFMF commander, and I want to reiterate that again.”

RFMF commander Major-General Ro Jone Kalouniwai said last week he had made it clear during the Commander’s Parade earlier this month that the constitutional process must be followed.

He said they would continue to abide by the rule of law and order and continue to respect the decision of the people for voting in this particular government — the ruling coalition of Sitiveni Rabuka, who is both a former coup leader and prime minister.

Meanwhile, he said Thursday’s event was about commemorating 48 years of existence and the institution’s humble beginning in 1975.

Potential AUKUS deal could divide NZ and Pacific, says academic

An international relations professor says that if New Zealand joins AUKUS it could impact on its relations with Pacific countries.

AUKUS is a security agreement between Australia, the UK and the US, which will see Australia supplied with nuclear-powered submarines.

That has raised concern in the Pacific, which is under the South Pacific Nuclear Free Zone Treaty, also known as the Treaty of Rarotonga.

The topic has come up while US Secretary of State Antony Blinken visited New Zealand.

The visit came after he visited Tonga.

Robert Patman, professor of international relations at the University of Otago, said New Zealand’s views on non-nuclear security are shared by the majority of the Association of Southeast Asian Nations (ASEAN) members and also the Pacific Island states.

“Even if New Zealand joined AUKUS in a non-nuclear fashion, technically, it may be seen through the eyes of others as diluting our commitment to that norm,” Professor Patman said.

Sharing defence information
Professor Patman explained that “pillar 1” of AUKUS is about providing nuclear-powered submarines to Australia over two or three decades, and “pillar 2” is to do with sharing information on defence technologies.

“We haven’t closed the door on it, but it’s a considerable risk from New Zealand’s point of view, because a lot of our credibility is having an independent foreign policy.”

Asked about New Zealand’s potential membership in AUKUS, Blinken said work on pillar 2 was ongoing.

“The door is very much open for New Zealand and other partners to engage as they see appropriate,” he said.

“New Zealand is a deeply trusted partner, obviously a Five Eyes member.

“We’ve long worked together on the most important national security issues.”

New Zealand Foreign Minister Nanaia Mahuta said the government was exploring pillar 2 of the deal.

Not committed
But she said New Zealand had not committed to anything.

Mahuta said New Zealand had been clear it would not compromise its nuclear-free position, and that was acknowledged by AUKUS members.

Patman said that statement was reassurance for Pacific Island states.

“[New Zealand is] party to the Treaty of Rarotonga,” he said.

“We have to weigh up whether the benefits of being in pillar 2 outweigh possible external perception that we’re eroding our commitment, to being party to an arrangement which is facilitating the transfer of nuclear-powered submarines to Australia.”

He said New Zealand had also been in talks with NATO about getting access to cutting-edge technology, so it was not dependent on AUKUS for that.

Three dead in Auckland CBD shooting, including gunman, police confirm

RNZ News

Three people have been killed in a shooting in Auckland central business district today, including the gunman.

Six people were also wounded, including two police officers.

Police say the situation is now contained.

Prime Minister Chris Hipkins told media a witness called the incident in at 7.23am, reporting there was a man with a gun shooting inside a construction site on lower Queen Street.

The gunman moved through the construction site shooting a pump-action shotgun.

When he reached the upper levels he hid inside an elevator shaft.

Police attempted to engage with him, but the gunman fired further shots, before he was found dead a short time later, they say.

The New Zealand Herald reports Prime Minister Hipkins praised the “heroic” actions of emergency services.

He said there was no identified “political or ideological motivation” for the shooter and as such, there was no need to change the national security risk.

The government has spoken to FIFA organisers today and the Women’s Football World Cup tournament will proceed as planned with the opening match tonight between New Zealand and Norway.

Police Commissioner Andrew Coster later confirmed the dead gunman was on home detention and had previous convictions. He was named as Matu Tangi Matua Reid, 24, reports RNZ News.

Coster said the shooter was a worker at the construction site, and had an exemption from home detention to go to work.

At 7.22am police received multiple emergency calls about a person shooting a gun on the third floor of a building under construction on lower Queen Street. Commissioner Coster said officers arrived on the scene within minutes.

“The offender made his way up the building site, discharging his firearm on multiple occasions. Police entered in the building within 10 minutes,” he said.

The police commissioner said the gunman fired at police, wounding an officer, and shots were then exchanged.

“The offender was later found deceased.”

The wounded police officer was taken to hospital in a critical condition, but has since stabilised.

Macron keen on Varirata forest lookout for bilateral talks with PNG

By Gorethy Kenneth in Port Moresby

One of the world’s top leaders and G7 member French President Emmanuel Macron had his one-on–one bilateral talks with PNG leaders at a forest lookout in Central Province today.

Prime Minister James Marape told media at APEC Haus yesterday that Macron himself wanted a walk through the famous Varirata Park in Sogeri and spend a few minutes at the lookout before heading back for more bilateral talks.

With his interest in climate change, Papua New Guinea will seek France’s support for an ultimate climate financing — a suggestion for a “Green Bond”.

Prime Minister Marape presented a ceremonial eagle wood spear with PNG totems to President Macron as a symbol of friendship with a message — “this spear will go with you all over the world and back to your country”.

“It may be just a piece of wood but this is a historical symbol of you taking a piece of PNG with you PM,” Marape said.

“Long live our friendship.”

Marape told media yesterday security and other details for Macron’s visit were all in place.

Forest nation identity ‘amplified’
“Everything is set, police and every security personnel are on standby,” Marape said.

“He himself said he wants to go to a forest. Papua New Guinea is a forest nation, with heaps of tuna, oil and gas.

“We are a forest nation so our identity as a forest nation will be amplified.

“The French President is a big leader in his own right — [leader of] a G7 member country, so him coming here is a privilege for us.

“There are conversations we cannot converse in terms of our forest conservation.”

France is member of the Group of Seven (G7) which is an informal grouping of seven of the world’s most advanced economies, including Canada, Germany, Italy, Japan, United Kingdom and the United States, as well as the European Union.

“I had asked him in our Gabon meeting for him to be a forest advocate for the global nations so that’s why we going to Varirata is symbolic,” Marape said.

“We will have a 30-minute walk in the forest and then instead of having a one-on-one meeting here (APEC Haus), we set the Varirata Park and at the Lookout Point,” he said.

“Then much of these will be, you know, for me as a nation, forest is a resource. If we have to conserve, people must pay especially those with big carbon footprints, they must pay for the conservation of our forest.”

President Macron is also visiting Fiji, New Caledonia and Vanuatu on his historic Pacific tour.

France, Vanuatu agree to sort out ‘southern land’ border dispute

By Doddy Morris in Port Vila

French President Emmanuel Macron and Vanuatu Prime Minister Ishmael Kalsakau have reached an agreement to settle the “land problem” in the southern region of Vanuatu before the end of this year.

Prime Minister Kalsakau made this declaration during his speech at the 7th Melanesian Arts and Cultural Festival (MACFEST) in Saralana Park yesterday afternoon, coinciding with President Macron’s visit to the festival.

“We have talked about a topic that is important to the people of Vanuatu in relation to the problem for us in the Southern Islands. The President has said that we will resolve the land problem between now and December,” he said.

Though not explicitly naming them, it is evident that the southern land problem mentioned refers to the islands of Matthew and Hunter, located in the southern portion of Vanuatu, over which significant demands have been made.

In addition to this issue, the boundary between New Caledonia and Vanuatu remains unresolved.

The hope was that during President Macron’s visit, Prime Minister Kalsakau — carried in a traditional basket by Aneityum bearers during the opening of MACFEST 2023 — would address the Matthew and Hunter issue with the French leader.

As part of Vanuatu’s traditional practice, Kalsakau and President Macron participated in a kava-drinking ceremony, expressing their wish for the fruitful resolution of the discussed matters.

Matthew and Hunter are two small and uninhabited volcanic islands in the South Pacific, located 300 kilometres east of New Caledonia and south-east of Vanuatu.

Both islands are claimed by Vanuatu as part of Tafea province, and considered by the people of Aneityum to be part of their custom ownership. However, since 2007 they had also been claimed by France as part of New Caledonia.

Elation over statement
The announcement of the two leaders’ commitment to resolving the southern land issue was met with elation among the people of Vanuatu, particularly in the Tafea province.

“France has come back to Vanuatu; President Macron has told me that it has been a long time, but he has come back today with huge support to help us more,” said Prime Minister Kalsakau, expressing gratitude.

The Vanuatu government head revealed that France had allocated a “substantial sum” of money to be signed-off soon, which would lead to significant development in Vanuatu.

This would include the reconstruction of French schools and hospitals, such as the Melsisi Hospital in Pentecost, which had been damaged by past cyclones.

In response to the requests made by PM Kalsakau and President Macron, the chiefs of the Tafea province conducted another customary ceremony to acknowledge and honour the visiting leaders.

President Macron at MACFEST 2023
More than 4000 people gathered yesterday at Saralana Park to witness the presence of President Macron and warmly welcome him to MACFEST 2023.

He delighted the crowd by delivering a speech in Bislama language, noting the significance of Vanuatu’s relationship with France and highlighting its special and historical nature.

“Let me tell you how pleased I am to be with you, not only as a foreign head of state but as a neighbour, coming directly from Noumea,” President Macron said.

He praised Prime Minister Kalsakau for fostering a strong bond between the two countries amid “various challenges and foreign interactions”, emphasising that their connection went beyond bilateral relations, rooted in their shared history.

President Macron further shared his satisfaction with the discussions he had with Kalsakau, expressing joy that his day could culminate with the celebration of MACFEST, symbolising the exchange between himself and Vanuatu’s PM.

“My delegation is thrilled to participate in the dances and demonstrations that bring together delegations from across the region, celebrating the strength and vitality of Melanesia and the spirit of exchange and sharing,” he said.

The President expressed his pride in being part of the region, particularly in New Caledonia, and witnessing the young teenagers of Melanesia coming together, dancing, and singing, driven by the belief that they will overcome the challenges of today and tomorrow.

Last night, President Macron departed for Papua New Guinea to continue his historic Pacific visit. He expressed his happiness in meeting members from PNG, Solomon Islands, Fiji, and other participating nations during MACFEST.

Long before women police officers came police ‘matrons’: who were they and what did they do?

Source: The Conversation (Au and NZ) – By Alice Neikirk, Lecturer, Criminology, University of Newcastle

This year marks a significant milestone for women in policing: the 125th anniversary of the first official recognition of a police matron in Australia.

However, women worked in this role for at least 50 years before receiving official recognition.

Known as “police matrons”, these women opened the door for other women to move into the police force as officers, yet their role is still unrecognised or dismissed as an extension of her husband’s policing duties.

While many Australians will have never heard of them, they were trailblazers for women in law enforcement.

Hidden women of history: Kate Cocks, the pioneering policewoman who fought crime and ran a home for babies – but was no saint


The female touch in policing

During the Victorian era, it was considered inappropriate for men to touch a woman who was not their wife or an immediate family member. This made men policing women (at least of certain social classes) difficult, particularly if they needed to search a female suspect. To get around this, police began to call on women to search arrestees for them.

Initially, these might have been whoever was nearby – a woman living near the police station, for example. But quickly it was recognised that a “female touch” was also helpful for comforting lost children, talking to female victims of crime, and occasionally soothing an unruly male arrestee. Neighbourhood women were not viewed as entirely suited for these more complex roles, but the wives of police officers were.

In Australia, the United States and the United Kingdom, early police stations had both temporary holding cells (a lock-up) and a residence for a police officer. The officer living on site was frequently married – these women became police matrons.

Police matrons in the Victorian era searched female offenders, were responsible for lost or arrested children, kept watch over mentally unwell inmates, and occasionally allowed families facing violence at home to stay in the station.

They also performed tasks we would not generally associate with the work of a police officer. They cleaned and maintained the cells, mended clothes, and hosted clothing drives for the poor. The police stations sometimes doubled as neighbourhood medical centres. These were all tasks that fell to the police matron. They fit within assumptions of the period regarding the natural, nurturing role of women.

Discrimination leading to innovation

Because these tasks were viewed as “naturally” women’s work, questions regarding compensation were skirted. For decades, these were not formal appointments. The matrons were not sworn in, they did not have access to a police pension, and they did not have any authority over male inmates (or male officers).

A few received a modest stipend based on the number of searches they conducted or if they performed an extended psychiatric watch. These matrons would be on-call 24 hours a day, and diaries kept by early matrons show the long hours they kept. Yet their activities were viewed as an extension of their husband’s role, not requiring separate pay.

These women did not go on patrol or have powers to arrest. But there is evidence that police matrons performed tasks that align with current approaches to policing.

For example, a key role of male police in the early Victorian era was to prevent crime by being out in the community: an officer’s presence alone would often deter offending.

Police matrons rarely worked outside of the station, but they did get to know the needs of their community and tried to identify causes of crime. They became advocates, trying to address what they saw as the root causes of crime: excessive consumption of alcohol leading to the violent breakdown of families. Matrons advocated for increased regulation of alcohol and for stations to provide sanctuary for domestic violence victims.

Police matrons paved the way for women to become police officers, and eventually achieve the highest ranks.
Lukas Coch/AAP

Today, these efforts would be understood as forms of problem-orientated policing: identifying a problem in a community and working with the community to devise solutions for the underlying causes of crime. We cannot go as far as claiming that police matrons started the movement towards problem-orientated policing. But we can recognise that they predated today’s “best practice in policing” model by roughly 150 years.

Women have made many inroads in policing, but barriers remain to achieving gender equity


Though we know police matrons were working in this field in the mid-1800s, and gained a degree of official recognition in the 1890s, it was not until 1915 that the New South Wales Police Department advertised two positions for women police officers.

These two positions attracted nearly 500 applications. The first two female police officers in NSW were not allowed to wear a uniform and had to sign a waiver releasing the police department of any responsibility for their safety. Their tasks were similar to police matrons – they were responsible for women and children that came in contact with the criminal justice system. It wasn’t until 1979 that female officers in Australia could carry a firearm, though they were required to keep it in their handbag.

Today, women make up over 30% of police in Australia and have reached the highest ranks as police commissioners. Although Australians may not know much about the early police matrons, it was they who, more than 100 years ago, paved the way for all this to happen.

You’ve heard the annoyingly catchy song – but did you know these incredible facts about baby sharks?

Source: The Conversation (Au and NZ) – By Jaelen Nicole Myers, PhD Candidate, James Cook University

“Baby shark doo-doo doo-doo doo-doo, baby shark doo-doo doo-doo doo-doo …” If you’re the parent of a young child, you’re probably painfully familiar with this infectious song, which now has more than 13 billion views on YouTube.

The Baby Shark song, released in 2016, has got hordes of us singing along, but how much do you really know about baby sharks? Do you know how a baby shark is born, or how it survives to become an apex predator?

I study coastal marine ecology. I believe baby sharks are truly fascinating, and I hope greater public knowledge about these creatures will help protect them in the wild.

So sink your teeth into this Q&A on the weird and wonderful world of baby sharks.

How are baby sharks conceived and born?

To the human eye, shark courtship practices may seem barbaric. Males typically attract the attention of a female by biting her. If successful, this is generally followed by even toothier bites to hold on during copulation. Females can carry the scars of these encounters long after the mating season is over.

The act of copulation itself is comparable to that of humans. The male inserts its sexual organ, known as a “clasper”, into the female and releases sperm to fertilise the eggs.

However, in extremely rare cases, sharks can reproduce asexually – in other words, embryos develop without being fertilised. This occurred at a Queensland aquarium in 2016, when a zebra shark gave birth to a litter of pups despite not having had the chance to mate in several years.

Sharks give birth in a variety of ways. Some species produce live pups, which swim away to fend for themselves as soon as they’re born. Others hatch from eggs outside the mother’s body. Remnants of these egg cases have been found washed up on beaches across the world.

How big is a litter of shark pups?

Litter size across sharks varies considerably. For example, the grey nurse shark starts with several embryos but only two are born. This is because the embryos actually eat each other while in utero! This leaves only one survivor in each of the mother’s two uteruses.

Intrauterine cannibalism may seem disturbing but is nature’s way of ensuring that the strongest pups get the best chance of survival.

In contrast, other species such as the whale shark use a completely different strategy to ensure some of their offspring survive: having hundreds of pups in a single litter.

Where do baby sharks live?

The open ocean is a dangerous place. That’s why pregnant female sharks often give birth in shallow coastal waters known as “nurseries”. There, baby sharks are better protected from harsh environmental conditions and roaming predators, including other sharks.

Sites for shark nurseries include river mouths, estuaries, mangrove forests and coral reef flats.

For example, the white shark has established nursery grounds along the east coast of Australia, where babies may remain for several years before moving to deeper waters.

Although most types of sharks are confined to saltwater, the bull shark can live in freshwater habitats. Bull shark pups born near river mouths and estuaries often migrate upstream (sometimes vast distances inland) to escape being preyed upon.

When are baby sharks born?

Sharks, like most animals in the wild, generally give birth during periods that provide favourable conditions for their offspring.

In Australia, for example, scalloped hammerheads and bull sharks tend to breed in the wet summer months when nursery grounds are warmer and there are rich feeding opportunities.

How long do baby sharks take to grow up?

Sharks grow remarkably slowly compared to other fish and remain juveniles for a long time. Although some species mature in a few years, most take considerably longer.

Take the Greenland shark – the world’s longest living shark. It can live to at least 250 years and according to recent research, it’s thought to take more than a century to reach sexual maturity.

Surfers share their waves with sharks, but fear not


What threats do baby sharks face?

While small, sharks must eat or be eaten – all the while enduring the elements and finding enough food to survive and grow.

Yet there is another challenge: humans. In fact, we are the greatest threat to sharks.

Shark nurseries are heavily concentrated in coastal zones, and often overlap with human activities such as fishing, boating and coastal development. And because sharks grow so slowly, they are particularly to vulnerable to overfishing because when populations decline, they can take a long time to bounce back.

Much more to learn

Scientists are still working to understand the life cycles of the 500-plus species of sharks in our oceans. Each time I hear the song Baby Shark, it reminds me there’s a lot more work to do.

It’s crucial to keep monitoring and studying these baby wonders of the deep, to ensure shark populations survive and we maintain the delicate balance of our underwater ecosystems.

More than a picture: how the work of documentary photographer Raphaela Rosella is defined by co-creation

Source: The Conversation (Au and NZ) – By Tom Williams, Lecturer – Visual Arts, University of Wollongong

Documentary photographers have traditionally aspired to tell other people’s stories. For 15 years, artist Raphaela Rosella and the women close to her have forged their own complex visual narratives, despite frequent interventions by the criminal justice system.

Rosella is an Italian-Australian documentary artist devoted to long-term, socially engaged collaborative projects made with participants from Nimbin, Casino, Lismore and Moree in regional New South Wales.

Aware that photographs can enable stereotypes and mislead viewers, she decided early in her career the people she photographed should be given ongoing control of their representation. This means active collaboration in making images and a body of work, as well as continually seeking consent if sharing it with an audience.

You’ll Know It When You Feel It at Brisbane’s Institute of Modern Art has evolved through these relationships.

Rosella and her co-creators have sought to reclaim and counteract the narratives formed by state records, instead telling stories of the love they feel for family and the challenges they’ve faced: both together and when separated by the geography of prison custody.

Can a photograph change the world?


Welcomed into a home

Rosella is close to the women she works with, and knows they have been routinely marginalised and denied freedoms.

Some of the audio-visual archive was produced by participants while imprisoned, in response to a legal system that confronted them at a young age. The women see their collaborative work as a “site of resistance” where they can detach their identities from the procedures and labels imposed by bureaucracy.

Rather than granting sole storytelling agency to one artist or organisation, these women take a central role in communicating their own histories and perspectives.

The show feels like being welcomed into someone’s home: there are fabric curtains, handwritten cards, family photos, the reassuring sound of nearby voices.

This warm familiarity contrasts with the dehumanising language of the official documents on display: “At no time are photographs to be taken of the inmate”.

Each section of the exhibition is accompanied by a short text that reads like the opening lines of a personal letter. We’re entrusted with intimate moments and heartfelt correspondence. There are no image titles or dates on most of the photographs or videos, as if in defiance of the classificatory legal papers interwoven throughout.

The first image we see as we enter is a portrait coauthored by Kamilaroi/Biripi woman Nunjul Townsend. She meets our gaze with an intensity of emotion that reflects the profound bond she has with friend and artistic partner Rosella.

Next to it, a tenderly made photograph of Nunjul and her young son embracing is placed inside a sterile grid of blank “statement of truth” court documents.

The juxtaposition is moving: love between mother and son can’t be reduced to written transcripts – or even captured by a camera. But throughout the show the kinship that connects the group is palpable.

Crucial questions

Each participant has an individual curated space within the gallery, including Rosella and her identical twin. Rosella doesn’t shy away from revealing her own story to the viewer in self-portaits, video and wall text, or reflecting critically on her process (“the camera was enabling your addiction”).

Many of the people whose lives we engage with in the show are Aboriginal, and all have been impacted by violence.

One participant, Tammara, was killed in 2020 after the pair had been working together for a decade. An image of an empty Jim Beam bottle embedded in a wall speaks of the terror of domestic violence that is so sickeningly incessant in Australia.

The space dedicated to Kathleen “Rowrow” Duncan is one of the most affecting. Wall text and a small, handwritten note from mother to her newborn baby tell us that Rowrow is under prison guard. She has given birth and will soon return to a cell.

The majority of this space, from floor to wall, is filled by a transcript that maps Rowrow’s transfers from prison to prison over four years. I counted 30 relocations. It’s hard to imagine the effect this would have on a person’s sense of home; or hope.

In a note Rosella has written to co-creator Tricia, Rosella laments how Tricia’s partner had only “spent three of his birthdays on the outside since he was nine”.

One large wall in the exhibition is filled from floor to ceiling with a mosaic of photos, contact sheets, handwritten notes, drawings, redacted documents and letters (many of them posted from behind bars). Formal portraits are assembled alongside childrens’ drawings and intimate correspondence.

There is no visual hierarchy in the installation: each element speaks of a life, a shared experience, a human connection.

As an audience, we are driven to ask questions. Why are Aboriginal and Torres Strait Islander women imprisoned so disproportionately? Why are many disadvantaged kids who come into contact with law enforcement caught in “cycles of incarceration”? Why don’t we properly address intergenerational trauma?

The strength of You’ll Know It When You Feel It is how it makes us connect with real stories that transcend statistics and theoretical debates.

Collaborative dialogue

Documentary photographers have historically sought to reveal problems and inequalities in the world, fuelled by a desire to provoke change.

Lewis Hine famously played a role in reforming child labour laws in the USA through his images of young children at work. Visual storytellers are documenting the effects of climate change.

But documentary practice has been criticised by scholars for benefiting privileged photographers and institutions too often, advancing careers under the guise of concerned activism at the expense of their subjects.

Rosella, by contrast, engages in a genuine collaborative dialogue. Exhibition and publication are not the driving force.

This project is a rare example of artwork catalysing practical change. These photographs have been used to influence legal outcomes like the length of jail sentences and granting of parole. The voices of participants are heard and preserved.

The final room of the exhibition contains HOMEtruths, an immersive three channel video installation that intercuts home movies from the collaborators with cinematic depictions of family and Country.

It is an absorbing, hope-affirming work that highlights connection to loved ones and significant places across generations. We experience the ancient landscape the artists are part of. Newborn lives engender fresh optimism.

You’ll Know It When You Feel It is at the Institute of Modern Art, Brisbane, until August 19.

How do we keep women’s football clean? Start paying players a fair wage

Source: The Conversation (Au and NZ) – By Catherine Ordway, Associate Professor Sport Management and Sport Integrity Lead, University of Canberra

As the Women’s World Cup grows in size and stature, it’s not surprising concerns are also being raised about match-fixing and the integrity of the sport.

Women’s sport has traditionally not been considered high risk when it comes to match-fixing for a few reasons, including the few gambling options available to punters.

For example, when Australia hosted the men’s AFC Asian Cup and Cricket World Cup in 2015, the Australian Federal Police laid out plans for countering the risk of organised crime infiltration and match-fixing. The women’s Netball World Cup, which also took place in Australia that year, did not feature in its preparations because it was deemed “low risk”.

By the time the FIFA Women’s World Cup was held in France in 2019, however, the football governing body was not taking any chances. It established a monitoring hub for the tournament and worked with Interpol, the French police, France’s betting regulator and financial crime prosecutors to develop the best strategies for preventing any match-fixing incidents.

A similar task force has been set up for this year’s Women’s World Cup in Australia and New Zealand, including the FBI, Interpol, the UN Office on Drugs and Crime, Sport Integrity Australia, the New Zealand Police and Sportradar, a sport betting data provider.

As sports lawyer Laura Douglas warned in a 2016 analysis on match-fixing, the increasing commercialisation and globalisation of women’s sport – coupled with the poor pay and lack of other support services offered to players – has created a powder keg waiting to explode.

Long-range goals: can the FIFA World Cup help level the playing field for all women footballers?


Gambling companies are not only increasingly taking bets on women’s professional sports – millions were wagered on matches at the 2019 Women’s World Cup – but also in community-level sporting events and competitions involving minors.

Sportradar, which provides betting data to bookmakers and analyses the betting markets for potential match-fixing, found that half the suspicious cases it identified in domestic leagues in 2021 came from third-tier leagues or lower, including regional and youth football. The report said:

Many of these competitions lack key integrity protections like bet monitoring and athlete education, making them vulnerable targets for match-fixers.

Pay disputes in women’s football

The most vulnerable athletes are those who are not paid a fair wage or in a timely manner. Unfortunately, in women’s football, this is a major problem.

For this year’s World Cup, several members of the Nigerian women’s team, the Super Falcons, were contemplating a boycott of their first match due to a pay dispute.

The gender pay gap for the FIFA World Cup is US$370 million. It’s time for equity


The team had previously protested at the 2019 Women’s World Cup and last year’s Africa Cup of Nations over payments the players said they were owed by the federation.

The coach, Randy Waldrum, had also accused the Nigerian Football Federation of not properly supporting the team and interfering in his squad selections.

Nigeria’s opponent in its opening game, Canada, was also involved in a pay dispute with its federation, as were Jamaica and South Africa.

Why collective bargaining agreements are key

In 2015, the Australian women’s team, the Matildas, went on strike in an effort to increase the minimum wage they were paid and improve conditions for the national team (and later national league players).

It took another four years before the Professional Footballers Australia, the players’ union, and Football Australia were able to sign a new collective bargaining agreement, which would guarantee an equal split of all commercial revenue between the men’s and women’s national teams.

However, the Professional Footballers Australia has chosen not to follow the US model of pooling the prize money offered at the World Cup and dividing it equally among the men’s and women’s teams. The union believes this won’t address the inequity created by FIFA, which it could right with a stroke of the pen. (Prize money at the current Women’s World Cup has increased substantially, but is still a quarter what the men received at the 2022 men’s World Cup.)

Changing the culture within FIFA might be a challenge. One high-ranking football official, FIFA vice president Alejandro Dominguez, is quoted as saying he “doesn’t believe in equal pay” at the Women’s World Cup.

There was some progress at this year’s World Cup, though, with FIFA agreeing to pay all players at least US$30,000 individually.

The Matildas, together with the Australian players’ union, are now calling on FIFA to increase its resourcing for women’s football around the globe. They have particularly highlighted the need for union representation and collective bargaining agreements that guarantee minimum standards and pay.

And for its part, FIFA should be demanding accountability from its member federations on how the money it gives each country is used to support women’s football.

Nearly a decade ago, I argued that creating a stronger culture around integrity in sport will produce a better product on the field. Players will be less vulnerable to bribery, removing the temptation to deliberately throw a game.

Teams need to take a “winning well” approach, similar to the one adopted by the Australian Institute of Sport, which replaces the purely economic devaluation of athletes as “assets” with a more humanistic and inclusive approach that focuses on wellbeing and ethics of care.

If these recommendations are implemented internationally, it will go a long way to supporting the women’s game and strengthening integrity.

What happens in our body when we encounter and fight off a virus like the flu, SARS-CoV-2 or RSV?

Respiratory viruses like influenza virus (flu), SARS-CoV-2 (which causes COVID) and respiratory syncytial virus (RSV) can make us sick by infecting our respiratory system, including the nose, upper airways and lungs.

They spread from person to person through respiratory droplets when someone coughs, sneezes, or talks and can cause death in serious cases.

But what happens in our body when we first encounter these viruses? Our immune system uses a number of strategies to fight off viral infections. Let’s look at how it does this.

First line of defence

When we encounter respiratory viruses, the first line of defence is the physical and chemical barriers in our nose, upper airways, and lungs. Barriers like the mucus lining and hair-like structures on the surface of cells, work together to trap and remove viruses before they can reach deeper into our respiratory system.

Our defence also includes our behaviours such as coughing or sneezing. When we blow our nose, the mucus, viruses, and any other pathogens that are caught within it are expelled.

But sometimes, viruses manage to evade these initial barriers and sneak into our respiratory system. This activates the cells of our innate immune system.

Patrolling for potential invaders

While our acquired immune system develops over time, our innate immune system is present at birth. It generates “non-specific” immunity by identifying what’s foreign. The cells of innate immunity act like a patrol system, searching for any invaders. These innate cells patrol almost every part of our body, from our skin to our nose, lungs and even internal organs.

Our respiratory system has different type of innate cells such – as macrophages, neutrophils and natural killer cells – which patrol in our body looking for intruders. If they recognise anything foreign, in this case a virus, they will initiate an attack response.

Each cell type plays a slightly different role. Macrophages, for example, will not only engulf and digest viruses (phagocytosis) but also release a cocktail of different molecules (cytokines) that will warn and recruit other cells to fight against the danger.

Explainer: how does the immune system learn?


In the meantime, natural killer cells, aptly named, attack infected cells, and stop viruses from multiplying and invading our body further.

Natural killer cells also promote inflammation, a crucial part of the immune response. It helps to recruit more immune cells to the site of infection, enhances blood flow, and increases the permeability of blood vessels, allowing immune cells to reach the infected tissues.
At this stage, our immune system is fighting a war against viruses and the result can cause inflammation, fevers, coughs and congestion.

Launching a specific attack

As the innate immune response begins, another branch of the immune system called the adaptive immune system is activated.

The adaptive immune system is more specific than the innate immune system, and it decides on the correct tools and strategy to fight off the viral invaders. This system plays a vital role in eliminating the virus and providing long-term protection against future infections.

Specialised cells called T cells and B cells are key players in acquired immunity.

T cells (specifically, helper T cells and cytotoxic T cells) recognise viral proteins on the surface of infected cells:

B cells produce antibodies, which are proteins that can bind to viruses, neutralise them, and mark them for destruction by other immune cells.

B cells are a critical part of memory in our immune system. They will remember what happened and won’t forget for years. When the same virus attacks again, B cells will be ready to fight it off and will neutralise it faster and better.

Thanks to the adaptive immune system, vaccines for respiratory viruses such as the COVID mRNA vaccine keep us protected from being sick or severely ill. However, if the same virus became mutated, our immune system will act as if it was a new virus and will have to fight in a war again.

Neutralising the threat

As the immune response progresses, the combined efforts of the innate and adaptive immune systems helps control the virus. Infected cells are cleared, and the virus is neutralised and eliminated from the body.

As the infection subsides, symptoms gradually improve, and we begin to feel better and to recover.

But recovery varies depending on the specific virus and us as individuals. Some respiratory viruses, like rhinoviruses which cause the common cold, may cause relatively mild symptoms and a quick recovery. Others, like the flu, SARS-CoV-2 or severe cases of RSV, may lead to more severe symptoms and a longer recovery time.

Some viruses are very strong and too fast sometimes so that our immune system does not have the time to develop a proper immune response to fight them off.

Australians are living and working longer – but not necessarily healthier, new study shows

Source: The Conversation (Au and NZ) – By Kim Kiely, Lecturer, Statistics and Data Science, University of Wollongong

Australians are living and working longer, but a longer working life doesn’t always come with equivalent gains in healthy life.

Our analysis of change in life expectancy, health transitions and working patterns of more than 10,000 middle-aged Australians over the past two decades shows divergences in the number of years they can expect be in good health at work and in retirement.

In particular, education matters.

Those who left school before year 12 are losing years of healthy life, with their extra years in the workforce mainly comprising years of poor health. This is opposite to the trend among people who completed high school.

And while men and women experienced improvements in life expectancy, on average women are not gaining extra healthy life years.

Australians are being encouraged to extend their working life. For this to be sustainable and equitable, government and workplaces policies will need to make allowances for the health capacity of mature-age workers.

How we found our results

We’ve calculated healthy working life expectancies – the average number of years a person can expect to work in good health – for 50-year-olds using data from the Household, Income and Labour Dynamics in Australia (HILDA) survey. This is a longitudinal survey, meaning it seeks to interview the same households every year (about 17,000 people), enabling researchers to track life trajectories.

We identified two age groups within HILDA’s survey sample and followed each cohort for 10 years. The first group was 4,951 people aged 50 years and older in 2001. The second group was 6,589 people aged 50 years and older in 2011.

To estimate a healthy working life expectancy, we looked at how people transitioned in and out of good health and employment each year (based on survey data about their paid employment and long-term health conditions that limited participation in everyday activities).

By combining this with deaths data, we have calculated the average duration spent (i) working in good health, (ii) working in poor health, (iii) retired in good health, and (iv) retired in poor health.

Differences by education

The following graphs show our results, based on expectancies at age 50.

We show our data in this way, rather than total healthy life and working life expectancies from birth, because we followed people from age 50 and is this is the time from which workers start to plan for and transition into retirement.

Typically we understand life expectancies to be calculated from birth, but they can be estimated for any age. If you live to 50, your life expectancy is greater than when you were born.

Our first graph shows healthy life expectancies according to school completion. These estimates reflect the cumulative number of years a person will, on average, be healthy or unhealthy from age 50.

Across the two cohorts, those with low education lose 0.8 years of healthy life, while those with high education gain 0.8 years of healthy life.

As with all statistics, there is uncertainty in these estimates. (Our original analysis includes 95% confidence intervals but we do not show them here.)



These inequities are amplified in working-life expectancies, as the next graph shows. Among early school leavers, at age 50 healthy work years rose from 7.9 to 8.4 years, an increase of six months. But their years working in poor health rose from 2.7 to 3.6 years, a difference of 11 months.

In contrast, for those who completed year 12, at age 50 healthy work years rose from 9.6 to 10.5 years, an increase of 11 months. Their years working in poor health rose from 3.1 to 3.5 years, a difference of five months.



The next graph illustrates what this means in proportional terms.



The next graph shows working life expectancies by sex. Men, on average, will spend 25% of their remaining working years in poor health, and women 24%. These percentages have not changed over time.



These findings are consistent with previous analyses demonstrating social inequalities in health expectancies to have been maintained over time, and possibly widened in some circumstances. In that study, women with low educational attainment appeared to have had negligible improvements in life expectancy and lost healthy life years.

Implications for governments and employers

Australia has this month raised the age at which people qualify for the age pension to 67.

When the pension was introduced in 1908, the qualifying age was 65 for men and 60 for women. At the time, average life expectancy for Australians at birth was about 55 for men and 59 for women. Now it exceeds 81 for men and 85 for women (though is considerably lower for some groups, notably Indigenous Australians).

Australia’s ‘retirement age’ just became 67. So why are the French so upset about working until 64?


There’s an obvious rationale to prolong people’s working lives – to meet the challenges posed by population ageing and sustain the social security system. Nevertheless, consideration should be made for inequalities in life expectancy and health expectancy. For many ageing workers, health limitations constrain their capacity and opportunity to work.

To achieve longer working lives, workplaces will be need become more supportive of mature-age workers, including accommodating long-term health conditions.

This will likely involve addressing ageism in the workplace, increasing employer demand for older workers, creating appropriate work roles to fit the capacities and preferences of older workers, and providing pathways to lifelong education and training.

We may also need to rethink our idea of flexible work, which has largely centred around the needs of parents and younger workers. Many older workers will have expectations for an independent and active retirement period, and it should be possible for flexible work arrangements to accommodate this.

Finally, we should not discount the unpaid contributions made by many older adults through community service and providing care to loved ones.

Captivating and cathartic, a visionary and a truth-teller: playing Sinéad O’Connor’s music was my education

Source: The Conversation (Au and NZ) – By Toby Martin, Music historian, University of Sydney

Sinéad O’Connor was well known for her deeply emotional voice, her outspoken stance on political issues – especially her critique of the Catholic Church – and her explorations of spiritualism and religion, but what I want to talk about, mostly, was her extraordinary songwriting.

O’Connor’s first two albums The Lion and the Cobra (1987) and I Do Not Want What I Have Not Got (1990) made a huge impression on me when I was just starting to get into music and songwriting in my last year of high school.

I cottoned onto these records a bit late (I was in Year 12 in 1993) but sometimes quality things take a while to filter through to suburban teenage Australian minds. Those records cut right through the other stuff I was listening to: guitar bands with men mostly.

O’Connor’s music was different.

Here was music that focused right in on the voice and the lyrics. Music that told stories full of detail and delivered with sadness and tenderness and anger.

O’Connor was a visionary and a truth-teller. But she was also an important songwriter. She was a highly thoughtful and supple artist who was able to craft songs that combined observational detail, emotional heft and an ethical conscience.

Her songs always felt personal, rather than preachy.

Sinéad O’Connor: a troubled soul with immense talent and unbowed spirit


A particular kind of passion

I think I probably first heard O’Connor because a girl at my school would play the song Troy on guitar and it was amazing. Troy was the first single from the first album, but did not become a huge hit.

But it was always a cult favourite – a six minute micro-opus about the end of a relationship – with the kind of opening that put you right there in the moment:

I remember it
Dublin in a rainstorm
Sitting in a long grass in summer
Keeping warm.

And then the allusion to epic Greek myth. What was this!?

On Troy, O’Connor’s amazing voice was so apparent. Tender and lilting at the beginning with shades of traditional Irish folk singing, and then, out of the blue, shockingly angry.

I don’t think any other singer-songwriter performed anger so well. It was captivating and cathartic.

I suppose I must have seen the video for Nothing Compares 2 U around this time – it was everywhere – but really it was some of the other songs on her second album that connected with me. Especially the songwriting.

The Last Day of Our Acquaintance was just such vivid, plain writing:

This is the last day of our acquaintance
I’ll meet you later in somebody’s office

Very adult stuff for a 17-year-old, but I think that was also part of the appeal. This seemed like serious, grown-up songwriting, full of a particular kind of passion.

Also, it was just two chords so I could learn how to play it.

Black Boys on Mopeds managed to weave political commentary into something much more personal. The song addressed police brutality aimed at black British youth, but connected this to both global politics and issues closer to home in Ireland.

Margaret Thatcher on TV
Shocked by the deaths that took place in Beijing
It seems strange that she should be offended
The same orders are given by her.

O’Connor’s ability to contrast the personal detail with big picture politics was second to none and such a fine feature of her songwriting.

Emperor’s New Clothes rocked more, and became one of her better-known, radio-friendly songs, but was still full of great observant songwriting that resonated so much. “How could I possibly know what I want when I was only 21?” she sang.

I learnt to play these songs, and would play them all the time. They were an amazing education.

What connects these songs as a whole is their attention to detail and their compelling combination of fury and sadness, something that runs through the early period of her music.

Courage and insight

It was later, as I grew older, that I realised how extra-remarkable O’Connor’s achievements were given that she was an outspoken woman and an original thinker dealing with oppressive double standards and sexism.

She was so often dismissed by commentators as mad, rather than respected for her courage and insight.

As we know now, she was completely right about the things she spoke up about. In 1992 on Saturday Night Live she tore up a photo of the Pope in protest of the sexual abuse perpetrated and protected by the Catholic Church. It was highly prescient.

Watching that SNL video now, it is so striking how brave she is. Her critique of religion and politics and her later explorations of Islam and Rastafarianism showed her seeking, questioning mind. Just as her songs do.

O’Connor went on to make eight more very diverse albums, including interpretations of traditional Irish folk music and classic roots reggae music. Her singing voice and her political voice should be remembered and celebrated, as should her peerless songwriting.

In a way to process this heartbreaking news, I am spinning her records today and revelling in the power and magic of her songs and singing.

Ancient pathogens released from melting ice could wreak havoc on the world, new analysis reveals

Science fiction is rife with fanciful tales of deadly organisms emerging from the ice and wreaking havoc on unsuspecting human victims.

From shape-shifting aliens in Antarctica, to super-parasites emerging from a thawing woolly mammoth in Siberia, to exposed permafrost in Greenland causing a viral pandemic – the concept is marvellous plot fodder.

But just how far-fetched is it? Could pathogens that were once common on Earth – but frozen for millennia in glaciers, ice caps and permafrost – emerge from the melting ice to lay waste to modern ecosystems? The potential is, in fact, quite real.

Dangers lying in wait

In 2003, bacteria were revived from samples taken from the bottom of an ice core drilled into an ice cap on the Qinghai-Tibetan plateau. The ice at that depth was more than 750,000 years old.

In 2014, a giant “zombie” Pithovirus sibericum virus was revived from 30,000-year-old Siberian permafrost.

And in 2016, an outbreak of anthrax (a disease caused by the bacterium Bacillus anthracis) in western Siberia was attributed to the rapid thawing of B. anthracis spores in permafrost. It killed thousands of reindeer and affected dozens of people.

More recently, scientists found remarkable genetic compatibility between viruses isolated from lake sediments in the high Arctic and potential living hosts.

Earth’s climate is warming at a spectacular rate, and up to four times faster in colder regions such as the Arctic. Estimates suggest we can expect four sextillion (4,000,000,000,000,000,000,000) microorganisms to be released from ice melt each year. This is about the same as the estimated number of stars in the universe.

For 110 years, climate change has been in the news. Are we finally ready to listen?


However, despite the unfathomably large number of microorganisms being released from melting ice (including pathogens that can potentially infect modern species), no one has been able to estimate the risk this poses to modern ecosystems.

In a new study published today in the journal PLOS Computational Biology, we calculated the ecological risks posed by the release of unpredictable ancient viruses.

Our simulations show that 1% of simulated releases of just one dormant pathogen could cause major environmental damage and the widespread loss of host organisms around the world.

Digital worlds

We used a software called Avida to run experiments that simulated the release of one type of ancient pathogen into modern biological communities.

We then measured the impacts of this invading pathogen on the diversity of modern host bacteria in thousands of simulations, and compared these to simulations where no invasion occurred.

The invading pathogens often survived and evolved in the simulated modern world. About 3% of the time the pathogen became dominant in the new environment, in which case they were very likely to cause losses to modern host diversity.

In the worst- (but still entirely plausible) case scenario, the invasion reduced the size of its host community by 30% when compared to controls.

The risk from this small fraction of pathogens might seem small, but keep in mind these are the results of releasing just one particular pathogen in simulated environments. With the sheer number of ancient microbes being released in the real world, such outbreaks represent a substantial danger.

Extinction and disease

Our findings suggest this unpredictable threat which has so far been confined to science fiction could become a powerful driver of ecological change.

While we didn’t model the potential risk to humans, the fact that “time-travelling” pathogens could become established and severely degrade a host community is already worrisome.

Helle Astrid Kjær

We highlight yet another source of potential species extinction in the modern era – one which even our worst-case extinction models do not include. As a society, we need to understand the potential risks so we can prepare for them.

Notable viruses such as SARS-CoV-2, Ebola and HIV were likely transmitted to humans via contact with other animal hosts. So it is plausible that a once ice-bound virus could enter the human population via a zoonotic pathway.

While the likelihood of a pathogen emerging from melting ice and causing catastrophic extinctions is low, our results show this is no longer a fantasy for which we shouldn’t prepare.

They may only be microscopic – and far from the giant flesh-eating bugs you’ll see in sci-fi films – but the risks posed by pathogens shouldn’t be underestimated.

Will Ukraine be able to win over the Global South in its fight against Russian aggression?

I was running from my home in Kyiv as the Russian army occupied Bucha, Gostomel and Irpin in the early stages of its invasion of Ukraine in 2022.

By accident, I was leaving in a bus that a nearby international school was using to evacuate its students and staff. We drove for a long time, spending nights in bomb shelters with young people and their kids from China, the Middle East and India who had been studying and working in Ukraine.

When the war broke out, Ukraine was hosting tens of thousands of students from the Global South and was generally viewed as a partner in many countries.

But the war disrupted everything, including public opinion in many of these same countries. Now, Ukraine is struggling to gain support in the Global South, which has shown ambivalence about the invasion and been reticent to cut off ties with Russia.

Differences of opinion

After the February 2022 invasion, Ukraine’s leaders tried to rally the world’s support by focusing on a narrative of fighting for democracy and decolonisation.

As Ukrainians, we see our country as a bastion of democratic values and oppose the totalitarianism taking root in Russia. At the same time, Ukraine perceives the war as a national liberation effort – freedom from centuries of colonial oppression by Russia and the Soviet Union and the enforced dominance of the Russian language.

While the democratic narrative continues to resonate strongly with Ukraine’s western allies, the decolonisation narrative appears to have made little impact outside Ukraine – particularly in the Global South.

Most countries in the Global South, which includes Africa, Latin America and much of Asia and Oceania, used to be ruled by colonial powers. But it is clear there is not much solidarity with Ukraine’s goal of decisively ending Russia’s colonial influence in the former Soviet republic.

In fact, Ukrainian researchers monitoring the news in the Global South have found many media outlets are instead broadcasting manipulative pro-Kremlin messages.

For instance, the researchers found the Russian claim that Ukraine was being run by Nazis had gained popularity in some countries.

Specifically, there were reports in the Brazilian media that the CIA had organised a “Nazi coup” in Ukraine in 2014, referring to the country’s Revolution of Dignity. One Indian publication went even further, spreading the message that “descendants of the Nazis” came to power in Ukraine after the Orange Revolution in 2004.

These messages are helping to drive public opinion. A global survey conducted one year into the war revealed a large gap between the West and “the rest” when it comes to views of Russia and how the war should end.

As foreign policy analyst Bobo Lo writes, few countries in the Global South are keen to see a “triumphant West”, even if they have misgivings about Russian President Vladimir Putin’s actions.

They would much rather a world where US and Western power is counterbalanced by other centres of influence. Smaller players would retain agency, preserve their political autonomy, and perhaps leverage great power rivalry to their advantage.

Why does so much of the Global South support Russia?

To be clear, attitudes toward the devastating war vary considerably across the Global South – the region is no monolith of public opinion. And most countries maintain the importance of safeguarding Ukraine’s existing borders.

However, opinion polls in places like China, India and Turkey show a clear preference for the war to end now – even if that means Ukraine having to give up territory.

Clear majorities in Indonesia, Turkey and India also favour maintaining diplomatic relations with Russia.

Many countries of the Global South have a deep-seated “non-aligned” tradition dating back to the Cold War. Their colonial history reinforces a skepticism about the West. Some have also pointed out the West’s hypocrisy in criticising Russia’s invasion of Ukraine, given the US and its allies waged disastrous wars in Iraq, Afghanistan and elsewhere.

The war in Ukraine has also widened the gap between the Global North and South and exposed their different priorities.

While Western leaders are concerned about Russia’s disruption of the liberal democratic order and the rise of China, much of the Global South is focused on economic and development challenges, such as debt relief, food security and climate mitigation.

Even when emerging powers agree with the West, they often maintain good relations with Russia and China. This is what Brazil is currently doing: President Luiz Inácio “Lula” da Silva advocates maintaining his country’s neutrality towards Ukraine and Russia in order to avoid “any involvement, even indirect” in the war. He has, however, acknowledged Russia “has been wrong” to invade a neighbouring country.

Many countries have also pursued their own interests in the face of geopolitical polarisation. Some depend on Russia for wheat, energy and military hardware, or on China for investment, credit and trade.

Specifically, Russia has established a significant presence in parts of Africa. The private military contractor Wagner is operating across the continent, and the Russian and Chinese militaries recently held joint exercises with South Africa.

African leaders are also meeting with Putin this week in St. Petersburg as part of the second Russia-Africa Summit. The first edition, held in 2019, resulted in 92 agreements and contracts worth over US$11 billion.

Russia-Africa Summit: five things African leaders must achieve


Is the war of words lost?

Ukraine is aware that its relationship with the Global South is weak. Kyiv has struggled to get its message across to countries on the African continent, in particular, where it has only 10 embassies – a mere quarter of the Russian presence.

Ukraine is now working on opening more embassies and appointing ambassadors across Africa.

Ukrainian President Volodymyr Zelensky has also identified the Global South as a priority in international relations. For instance, his foreign minister, Dmytro Kuleba, embarked this week on his third tour of African countries. The trip was seen as pivotal, with Russia pulling out of a deal to allow Ukraine to export its grain, which is hugely important to many African countries.

Last month, Zelensky also met with seven African leaders in Ukraine, where he stressed the need for “real peace” in the conflict and a complete withdrawal of Russian troops from Ukraine.

Zelensky has promised to do more to ensure food security in the Global South, for example, through the creation of grain hubs. He also noted Ukraine is ready to significantly expand educational programs for students from Africa.

But will this be enough to persuade the Global South to do more to support Ukraine in the war?

There was once a street in Kyiv named after the Congolese freedom fighter Patrice Lumumba. Lumumba was vital to Africa’s struggle for independence and the end of the colonial rule. Before he was brutally murdered, he wrote:

What we wanted for our country — its right to an honourable life, to perfect dignity, to independence with no restrictions.

Ukrainians can only hope other countries can see their shared aspirations for a fully decolonised world.

Oppenheimer’s warning lives on: international laws and treaties are failing to stop a new arms race

Source: The Conversation (Au and NZ) – By Alexander Gillespie, Professor of Law, University of Waikato

Getty Images

J. Robert Oppenheimer – the great nuclear physicist, “father of the atomic bomb”, and now subject of a blockbuster biopic – always despaired about the nuclear arms race triggered by his creation.

So the approaching 78th anniversary of the Hiroshima bombing invites us to ask how far we’ve come – or haven’t come – since his death in 1967.

The Cold War represented all that Oppenheimer had feared. But at its end, then-US president George H.W. Bush spoke of a “peace dividend” that would see money saved from reduced defence budgets transferred into more socially productive enterprises.

Long-term benefits and rises in gross domestic product could have been substantial, according to modelling by the International Monetary Fund, especially for developing nations. Given the cost of global sustainable development – currently estimated at US$5 trillion to $7 trillion annually – this made perfect sense.

Unfortunately, that peace dividend is disappearing. The world is now spending at least $2.2 trillion annually on weapons and defence. Estimates are far from perfectly accurate, but it appears overall defence spending increased by 3.7% in real terms in 2022.

J. Robert Oppenheimer.

The US alone spent $877 billion on defence in 2022 – 39% of the world total. With Russia ($86.4 billion) and China ($292 billion), the top three spenders account for 56% of global defence spending.

Military expenditure in Europe saw its steepest annual increase in at least 30 years. NATO countries and partners are all accelerating towards, or are already past, the 2% of GDP military spending target. The global arms bazaar is busier than ever.

Aside from the opportunity cost represented by these alarming figures, weak international law in crucial areas means current military spending is largely immune to effective regulation.

The new nuclear arms race

Although the world’s nuclear powers agree “a nuclear war cannot be won and must never be fought”, there are still about 12,500 nuclear warheads on the planet. This number is growing, and the power of those bombs is infinitely greater than the ones dropped on Hiroshima and Nagasaki.

According to the United Nations’ disarmament chief, the risk of nuclear war is greater than at any time since the end of the Cold War. The nine nuclear-armed states (Britain, France, India, Pakistan, North Korea and Israel, as well as the big three) all appear to be modernising their arsenals. Several deployed new nuclear-armed or nuclear-capable weapons systems in 2022.

The US is upgrading its “triad” of ground, air and submarine launched nukes, while Russia is reportedly working on submarine delivery of “doomsday” nuclear torpedoes capable of causing destructive tidal waves.

While Russia and the US possess about 90% of the world’s nuclear weapons, other countries are expanding quickly. China’s arsenal is projected to grow from 410 warheads in 2023 to maybe 1,000 by the end of this decade.

Only Russia and the US were subject to bilateral controls over the buildup of such weapons, but Russian president Vladimir Putin suspended the arrangement. Beyond the promise of non-proliferation, the other nuclear-armed countries are not subject to any other international controls, including relatively simple measures to prevent accidental nuclear war.

Other nations – those with hostile, belligerent and nuclear-armed neighbours showing no signs of disarming – must increasingly wonder why they should continue to show restraint and not develop their own nuclear deterrent capacities.

The threat of autonomous weaponry

Meanwhile, other potential military threats are also emerging – arguably with even less scrutiny or regulation than the world’s nuclear arsenals. In particular, artificial intelligence (AI) is sounding alarm bells.

AI is not without its benefits, but it also presents many risks when applied to weapons systems. There have been numerous warnings from developers about the unforeseeable consequences and potential existential threat posed by true digital intelligence. As the Centre for AI Safety put it:

Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war.

UN fails to agree on ‘killer robot’ ban as nations pour billions into autonomous weapons research


More than 90 countries have called for a legally binding instrument to regulate AI technology, a position supported by the UN Secretary General, the International Committee of the Red Cross and many non-governmental organisations.

But despite at least a decade of negotiation and expert input, a treaty governing the development of “lethal autonomous weapons systems” remains elusive.

Plagues and pathogens

Similarly, there is a fundamental lack of regulation governing the growing number of laboratories capable of holding or making (accidentally or intentionally) harmful or fatal biological materials.

There are 51 known biosafety level-4 (BSL-4) labs in 27 countries – double the number that existed a decade ago. Another 18 BSL-4 labs are due to open in the next few years.

While these labs, and those at the next level down, generally maintain high safety standards, there is no mandatory obligation that they meet international standards or allow routine compliance inspections.

Finally, there are fears the World Health Organization’s new pandemic preparedness treaty, based on lessons from the COVID-19 disaster, is being watered down.

As with every potential future threat, it seems, international law and regulation are left scrambling to catch up with the march of technology – to govern what Oppenheimer called “the relations between science and common sense”.

Climb the stairs, lug the shopping, chase the kids. Incidental vigorous activity linked to lower cancer risks

Many people know exercise reduces the risk of cancers, including liver, lung, breast and kidney. But structured exercise is time-consuming, requires significant commitment and often financial outlay or travel to a gym. These practicalities can make it infeasible for most adults.

There is very little research on the potential of incidental physical activity for reducing the risk of cancer. Incidental activities can include doing errands on foot, work-related activity or housework as part of daily routines. As such they do not require an extra time commitment, special equipment or any particular practical arrangements.

In our study out today, we explored the health potential of brief bursts of vigorous physical activities embedded into daily life. These could be short power walks to get to the bus or tram stop, stair climbing, carrying heavy shopping, active housework or energetic play with children.

How was the study done?

Our new study included 22,398 UK Biobank participants who had never been diagnosed with cancer before and did not do any structured exercise in their leisure time. Around 55% of participants were female, with an average age of 62. Participants wore wrist activity trackers for a week. Such trackers monitor activity levels continuously and with a high level of detail throughout the day, allowing us to calculate how hard and exactly for how long people in the study were moving.

Participants’ activity and other information was then linked to future cancer registrations and other cancer-related health records for the next 6.7 years. This meant we could estimate the overall risk of cancer by different levels of what we call “vigorous intermittent lifestyle physical activity”, the incidental bursts of activity in everyday life. We also analysed separately a group of 13 cancer sites in the body with more established links to exercise, such such as breast, lung, liver, and bowel cancers.

Our analyses took into account other factors that influence cancer risk, such as age, smoking, diet, and alcohol habits.

What we found out

Even though study participants were not doing any structured exercise, about 94% recorded short bursts of vigorous activity. Some 92% of all bouts were done in very short bursts lasting up to one minute.

A minimum of around 3.5 minutes each day was associated with a 17–18% reduction in total cancer risk compared with not doing any such activity.

Half the participants did at least 4.5 minutes a day, associated with a 20–21% reduction in total cancer risk.

For cancers such as breast, lung and bowel cancers, which we know are impacted by the amount of exercise people do, the results were stronger and the risk reduction sharper. For example, a minimum of 3.5 minutes per a day of vigorous incidental activity reduced the risk of these cancers by 28–29%. At 4.5 minutes a day, these risks were reduced by 31–32%.

For both total cancer and those known to be linked to exercise, the results clearly show the benefits of doing day-to-day activities with gusto that makes you huff and puff.

Short bursts of physical activity during daily life may lower risk of premature death – new research


Our study had its limits

The study is observational, meaning we looked at a group of people and their outcomes retrospectively and did not test new interventions. That means it cannot directly explore cause and effect with certainty.

However, we took several statistical measures to minimise the possibility those with the lowest levels of activity were not the unhealthiest, and hence the most likely to get cancer – a phenomenon called “reverse causation”.

Our study can’t explain the biological mechanisms of how vigorous intensity activity may reduce cancer risk. Previous early-stage trials show this type of activity leads to rapid improvements in heart and lung fitness.

And higher fitness is linked to lower insulin resistance and lower chronic inflammation. High levels of these are risk factors for cancer.

Poor sleep is really bad for your health. But we found exercise can offset some of these harms


There is very little research on incidental physical activity and cancer in general, because most of the scientific evidence on lifestyle health behaviours and cancer is based on questionnaires. This method doesn’t capture short bursts of activity and is very inaccurate for measuring the incidental activities of daily life.

So the field of vigorous intensity activity and cancer risk is at its infancy, despite some very promising recent findings that vigorous activity in short bouts across the week could cut health risks. In another recent study of ours, we found benefits from daily vigorous intermittent lifestyle activity on the risk of death overall and death from cancer or cardiovascular causes.

In a nutshell: get moving in your daily routine

Our study found 3 to 4 minutes of vigorous incidental activity each day is linked with decreased cancer risk. This is a very small amount of activity compared to current recommendations of 150–300 minutes of moderate intensity or 75–150 minutes of vigorous intensity activity a week.

Vigorous incidental physical activity is a promising avenue for cancer prevention among people unable or unmotivated to exercise in their leisure time.

Our study also highlights the potential of technology. These results are just a glimpse how wearables combined with machine learning – which our study used to identify brief bursts of vigorous activity – can reveal health benefits of unexplored aspects of our lives. The future potential impact of such technologies to prevent cancer and possibly a host of other conditions could be very large.
