"She was the light of our lives": Family's tribute to hero kindergarten teacher

<p>Eleanor Bryant, 43, put herself in harm's way to <a href="https://www.oversixty.com.au/health/caring/heroic-kindergarten-teacher-identified-after-horror-crash" target="_blank" rel="noopener">save preschoolers</a> from a water tanker that crashed into the Macedon Ranges Montessori Pre-School in Riddells Creek on Tuesday. </p> <p>Now, the mother-of-two and speech pathologist has been remembered for her caring and down-to-earth nature by her family. </p> <p>Bryant's husband and his two young kids expressed their grief in a statement, saying they were "devastated by the loss". </p> <p>"She was the light of our lives: a cherished mother, wife, daughter and sister, and beloved by all her family and enormous network of friends," the statement read. </p> <p>"Her infectious smile, sense of humour and passion for life made her a joy to be around.</p> <p>"There is an enormous hole in our hearts today.</p> <p>"We thank the emergency services for their tireless work and the public for their beautiful tributes.</p> <p>"We will miss her like crazy. We thank you for respecting our privacy at this difficult time."</p> <p>Bryant has also been remembered for the impact she has made as a speech pathologist, with mum Becky Burton thanking her for changing her daughter Milla's life. </p> <p>"I've never met someone that was so engaging, so down to earth, so caring and would do whatever it took [to make sure Milla was happy]," Burton said.</p> <p>"[She was] the most beautiful mum and person just taken so tragically."</p> <p>Bryant tragically died at the scene after the crash, while a three-year-old boy was injured and taken to the Royal Children's Hospital with serious but non-life-threatening injuries to his arm.</p> <p>He remains in hospital and is in a stable condition. </p> <p>The driver of the truck was also taken to the Royal Melbourne Hospital in a stable condition after the "experienced 68-year-old driver is understood to have suffered a medical episode".</p> <p>Parents and family members have since visited the kindergarten and laid flowers and cards as a tribute to Bryant. </p> <p>Family friend Walter Lucas held back tears as he remembered the beloved mother-of-two, saying: "She saved that kid's life.That kid is now going to go off and live their whole life. For her to take her life for that kid, she is more than a hero.</p> <p>"She's a superhero."</p> <p>Clinton Zammit, whose children went to the kindergarten, described the situation as "really sad".</p> <p>"I feel sorry for the woman who lost her life, her kids waking up today and having no mother. An unsung hero to push away kids and not care about anything else but the kids.</p> <p>"It hits home when my kids used to come here and there are other families involved.</p> <p>"We are a close-knit community, we are small but have big hearts and this will affect the community for a while."</p> <p>The pre-school is expected to remain closed for the coming weeks, and ongoing counselling has been offered onsite.</p> <p><em>Images: Nine</em></p>

Why do organisations still struggle to protect our data? We asked 50 professionals on the privacy front line

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/jane-andrew-10314">Jane Andrew</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/dr-penelope-bowyer-pont-1550191">Dr Penelope Bowyer-Pont</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/max-baker-25553">Max Baker</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>More of our personal data is now collected and stored online than ever before in history. The rise of data breaches should unsettle us all.</p> <p>At an individual level, data breaches can compromise our privacy, cause harm to our finances and mental health, and even enable identity theft.</p> <p>For organisations, the repercussions can be equally severe, often resulting in major financial losses and brand damage.</p> <p>Despite the increasing importance of protecting our personal information, doing so remains fraught with challenges.</p> <p>As part of a <a href="http://www.doi.org/10.25910/psq3-q365">comprehensive study</a> of data breach notification practices, we interviewed 50 senior personnel working in information security and privacy. Here’s what they told us about the multifaceted challenges they face.</p> <h2>What does the law actually say?</h2> <p>Data breaches occur whenever personal information is accessed or disclosed without authorisation, or even lost altogether. <a href="https://www.abc.net.au/news/2024-06-20/optus-hack/104002682">Optus</a>, <a href="https://www.abc.net.au/news/2022-11-09/medibank-data-release-dark-web-hackers/101632088">Medibank</a> and <a href="https://www.afr.com/technology/canva-criticised-after-data-breach-exposed-139m-user-details-20190526-p51r8i">Canva</a> have all experienced high-profile incidents in recent years.</p> <p>Under Australia’s <a href="https://www8.austlii.edu.au/cgi-bin/viewdb/au/legis/cth/consol_act/pa1988108/">privacy laws</a>, organisations aren’t allowed to sweep major cyber attacks under the rug.</p> <p>They have to notify both the regulator – the Office of the Australian Information Commissioner (OAIC) – and any affected individuals of breaches that are likely to result in “<a href="https://www8.austlii.edu.au/cgi-bin/viewdb/au/legis/cth/consol_act/pa1988108/#:%7E:text=Whether%20access%20or%20disclosure%20would%20be%20likely%2C%20or%20would%20not%20be%20likely%2C%20to%20result%20in%20serious%20harm%2D%2Drelevant%20matters%20%C2%A0">serious harm</a>”.</p> <p>But according to the organisational leaders we interviewed, this poses a tricky question. How do you define serious harm?</p> <p>Interpretations of what “serious harm” actually means – and how likely it is to occur – vary significantly. This inconsistency can make it impossible to predict the specific impact of a data breach on an individual.</p> <p>Victims of domestic violence, for example, may be at increased risk when personal information is exposed, creating harms that are difficult to foresee or mitigate.</p> <h2>Enforcing the rules</h2> <p>Interviewees also had concerns about how well the regulator could provide guidance and enforce data protection measures.</p> <p>Many expressed a belief the OAIC is underfunded and lacks the authority to impose and enforce fines properly. The consensus was that the challenge of protecting our data has now outgrown the power and resources of the regulator.</p> <p>As one chief information security officer at a publicly listed company put it:</p> <blockquote> <p>What’s the point of having speeding signs and cameras if you don’t give anyone a ticket?</p> </blockquote> <p>A lack of enforcement can undermine the incentive for organisations to invest in robust data protection.</p> <h2>Only the tip of the iceberg</h2> <p>Data breaches are also underreported, particularly in the corporate sector.</p> <p>One senior cybersecurity consultant from a major multinational company told us there is a strong incentive for companies to minimise or cover up breaches, to avoid embarrassment.</p> <p>This culture means many breaches that should be reported simply aren’t. One senior public servant estimated only about 10% of reportable breaches end up actually being disclosed.</p> <p>Without this basic transparency, the regulator and affected individuals can’t take necessary steps to protect themselves.</p> <h2>Third-party breaches</h2> <p>Sometimes, when we give our personal information to one organisation, it can end up in the hands of another one we might not expect. This is because key tasks – especially managing databases – are often outsourced to third parties.</p> <p>Outsourcing tasks might be a more efficient option for an organisation, but it can make protecting personal data even more complicated.</p> <p>Interviewees told us breaches were more likely when engaging third-party providers, because it limited the control they had over security measures.</p> <p>Between July and December 2023 in Australia, there was an increase of <a href="https://www.oaic.gov.au/privacy/notifiable-data-breaches/notifiable-data-breaches-publications/notifiable-data-breaches-report-july-to-december-2023">more than 300%</a> in third-party data breaches compared to the six months prior.</p> <p>There have been some highly publicised examples.</p> <p>In May this year, many Clubs NSW customers had their personal information potentially <a href="https://www.rimpa.com.au/resource/more-than-a-million-australian-data-records-potentially-exposed-in-nsw-club-and-pub-data-breach.html#:%7E:text=Outabox%2C%20the%20IT%20services%20provider,and%20has%20notified%20law%20enforcement">breached</a> through an attack on third-party software provider Outabox.</p> <p>Bunnings suffered a <a href="https://australiancybersecuritymagazine.com.au/bunnings-customer-data-compromised/">similar breach</a> in late 2021, via an attack on scheduling software provider FlexBooker.</p> <h2>Getting the basics right</h2> <p>Some organisations are still struggling with the basics. Our research found many data breaches occur because outdated or “legacy” data systems are still in use.</p> <p>These systems are old or inactive databases, often containing huge amounts of personal information about all the individuals who’ve previously interacted with them.</p> <p>Organisations tend to hold onto personal data longer than is legally required. This can come down to confusion about data-retention requirements, but also the high cost and complexity of safely decommissioning old systems.</p> <p>One chief privacy officer of a large financial services institution told us:</p> <blockquote> <p>In an organisation like ours where we have over 2,000 legacy systems […] the systems don’t speak to each other. They don’t come with big red delete buttons.</p> </blockquote> <p>Other interviewees flagged that risky data testing practices are widespread.</p> <p>Software developers and tech teams often use “production data” – real customer data – to test new products. This is often quicker and cheaper than creating test datasets.</p> <p>However, this practice exposes real customer information to insecure testing environments, making it more vulnerable. A senior cybersecurity specialist told us:</p> <blockquote> <p>I’ve seen it so much in every industry […] It’s literally live, real information going into systems that are not live and real and have low security.</p> </blockquote> <h2>What needs to be done?</h2> <p>Drawing insights from professionals at the coalface, our study highlights just how complex data protection has become in Australia, and how quickly the landscape is evolving.</p> <p>Addressing these issues will require a multi-pronged approach, including clearer legislative guidelines, better enforcement, greater transparency and robust security practices for the use of third-party providers.</p> <p>As the digital world continues to evolve, so too must our strategies for protecting ourselves and our data.<!-- Below is The Conversation's page counter tag.

Who dies in a heat wave? How to help protect the vulnerable in our communities

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/myles-david-sergeant-1542267">Myles David Sergeant</a>, <a href="https://theconversation.com/institutions/mcmaster-university-930">McMaster University</a></em></p> <p>Extreme heat is a silent killer.</p> <p>From time to time, we hear about shocking cases of <a href="https://www.theguardian.com/world/2023/sep/24/football-player-heat-deaths-athlete">football players</a> and other athletes who die suddenly while exerting themselves on hot days. Those deaths are certainly tragic, but statistically they are very rare.</p> <p>Most deaths from extreme heat <a href="https://www.epa.gov/climate-indicators/climate-change-indicators-heat-related-deaths">are in older people</a>, who frequently die alone inside their homes. They often die slowly, as the heat creeps up to and sometimes past body temperature, especially when heat domes park themselves over cities and keep the temperature high all day and all night. When such deaths happen, they rarely make the news.</p> <p>Of all the climate change disasters our world is already experiencing, heat is the top killer, <a href="https://library.wmo.int/viewer/68500/download?file=1335_WMO-Climate-services-Health_en.pdf&amp;type=pdf&amp;navigator=1">as the World Meteorological Organization reported</a>. The planet was more than <a href="https://www.theguardian.com/environment/article/2024/jul/08/temperatures-1-point-5c-above-pre-industrial-era-average-for-12-months-data-shows">1.5 C above the pre-industrial baseline</a> for 12 consecutive months from July 2023 to June 2024. In July this year, we saw the hottest three days ever on record, prompting <a href="https://www.un.org/sg/en/content/sg/press-encounter/2024-07-25/secretary-generals-press-conference-extreme-heat">a special statement from United Nations Secretary-General Antonio Guterres</a>.</p> <h2>Health risks and heat</h2> <p><a href="https://www.ncbi.nlm.nih.gov/books/NBK499843/">Our bodies are made to dump excess heat</a> when we are too warm, but that process goes into reverse when the air is warmer than our core temperature. Our other main defence, sweating, doesn’t help when humidity saturates the air, making it impossible for our own moisture to evaporate.</p> <p>For the frail and elderly, who are more likely to be labouring with heart troubles, COPD or other challenges, simply sitting still in a heat wave requires an effort equivalent to walking on a treadmill. The effort is not great, but it is <a href="https://doi.org/10.1016/j.cjco.2021.10.002">steady and relentless</a>. It exhausts the body, sometimes to the <a href="https://doi.org/10.1016/S2542-5196(22)00117-6">point of no return</a>.</p> <p>Tracking heat-related deaths is challenging, and it’s changing as authorities become more aware of heat as a contributing or underlying factor to deaths by other causes. <a href="https://doi.org/10.2105/AJPH.2006.100081">A paper published by the <em>American Journal of Public Health</em></a> points out that the 1995 heat wave in Chicago likely contributed to hundreds more deaths than had first been attributed to heat itself.</p> <h2>Who is at risk?</h2> <p>Many people lack air conditioning or a way to get to a place that has it, such as a library, recreation centre or shopping mall. As a result, too many people in cities are forced to <a href="https://wmo.int/publication-series/2023-state-of-climate-services-health">endure long waves of heat</a> — waves that are occurring more frequently, lasting longer, and reaching higher temperatures — in a trend that appears set to continue getting worse.</p> <p>Air conditioning, <a href="https://www.lpm.org/news/2015-07-24/the-history-of-movie-theaters-and-air-conditioning-that-keeps-film-lovers-cool">once a luxury that drew people to summertime movie theatres on hot nights</a>, has become a necessity. Increasingly, it is also a legal requirement, as cities pass bylaws requiring landlords not to allow the temperature in their tenants’ quarters to rise above a certain level. Toronto has <a href="https://www.toronto.ca/home/311-toronto-at-your-service/find-service-information/article/?kb=kA06g000001xvbiCAA">such a bylaw</a> for rental units that have air conditioning available, capping indoor temps at 26 C between June 2 and Sept. 14.</p> <p>Such laws recognize the vulnerability of tenants who lack control over the temperature in their rental units, making heat death an especially urban tragedy, as confirmed in <a href="https://www150.statcan.gc.ca/n1/en/pub/82-003-x/2024006/article/00001-eng.pdf?st=e6jLNMuq">a recent Statistics Canada study</a> between 2000 and 2020. Deaths from extreme heat were more likely in cities with a higher percentage of renter households.</p> <p>During a single week-long heat wave in June 2021 — the year after the period captured in the Statistics Canada study — <a href="https://www.cbc.ca/news/canada/british-columbia/bc-heat-dome-sudden-deaths-570-1.6122316">B.C.’s chief coroner found that 570 people died from heat-related causes</a> — 79 per cent of them were seniors.</p> <h2>Taking action at the community level</h2> <p>From this Global North perspective, the community members who are most likely to die from extreme heat included:</p> <ul> <li>Those over 65</li> <li>Those with more than one chronic condition (including hypertension, mental health, diabetes, heart disease, lung disease)</li> <li>Socially disadvantaged populations in our communities</li> <li>Those with mobility issues</li> <li>Those experiencing social isolation (living alone)</li> <li>Tenants with lack of air conditioning</li> <li>Those living in an urban heat island</li> </ul> <p>This problem is not going away.</p> <p>Some of the <a href="https://www.intactcentreclimateadaptation.ca/wp-content/uploads/2022/06/UoW_ICCA_2022_04-Irreversible-Extreme-Heat.pdf">actions we can take</a> to protect our most vulnerable community members include:</p> <ul> <li>Increase awareness that excessive heat is not merely uncomfortable, but dangerous.</li> <li>Make sure people are warned about impending heat waves.</li> <li>Advocate for everyone to have access to air conditioning.</li> <li>Check on and support people who live alone, especially those with no air conditioning.</li> <li>Invite people over if you have air conditioning, or help them get to community cooling stations.</li> <li>Help vulnerable people who do not have air conditioning to improvise, by freezing wet cloths, for example, to take out and hang around their necks.

Are cats good for our health?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/susan-hazel-402495">Susan Hazel</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a></em></p> <p>Cats have lived with humans for <a href="https://www.nature.com/articles/s41559-017-0202">thousands of years</a>. And <a href="https://www.bbc.com/future/article/20240923-100-year-old-cat-memes-that-predate-the-internet">long before</a> cat memes and viral <a href="https://theconversation.com/tiktok-says-orange-cats-are-dumb-and-tortoiseshell-cats-have-an-attitude-but-how-true-is-that-218033">TikToks</a> took over the internet, they’ve been comforting us with their purrs and making us laugh with their weird antics.</p> <p>But what does the research say – are cats good for us?</p> <p>Living with a cat can have a profound – and sometimes surprising – effect on our physical and mental health. Still, living with cats is not without risks.</p> <h2>Part of the family</h2> <p>You may have heard cats don’t have owners, they have “staff”. In fact, multiple studies show the humans who live with them feel more like beloved relatives.</p> <p>In a <a href="https://www.mdpi.com/1660-4601/19/1/193">study</a> of 1,800 Dutch cat owners, half said their cat was family. One in three viewed their cat as a child or best friend and found them loyal, supportive and empathetic.</p> <p>Another US study developed a “<a href="https://www.frontiersin.org/journals/veterinary-science/articles/10.3389/fvets.2021.812922/full">family bondedness</a>” scale and found cats were just as important a part of families as dogs.</p> <p>Many cats would choose <a href="https://www.sciencedirect.com/science/article/abs/pii/S0376635716303424">human interaction</a> over food or toys. And <a href="https://link.springer.com/article/10.1007/s10071-022-01674-w">they can distinguish</a> when we are talking to them (rather than another human).</p> <p>In fact we’ve adapted to each other. Cats are <a href="https://www.nature.com/articles/s41598-020-73426-0">more likely</a> to approach human strangers who first give a “kitty kiss” – narrowing your eyes and blinking slowly. And research suggests cats have developed <a href="https://theconversation.com/why-cats-meow-at-humans-more-than-each-other-232865">specific meows</a> that tune into our nurturing instincts.</p> <p>What does this close relationship mean for health outcomes?</p> <h2>A sense of purpose</h2> <p>Owning a pet is associated with <a href="https://link.springer.com/article/10.1007/s00127-022-02332-9">less social isolation</a>. And <a href="https://www.cabidigitallibrary.org/doi/full/10.1079/hai.2021.0006">some cat owners</a> say “providing for the cat” increases their feelings of enjoyment and sense of purpose.</p> <p>But the benefits of the relationship may depend on how you relate to your cat.</p> <p><a href="https://www.mdpi.com/2076-2615/11/6/1601">One study</a> looked at different relationship styles between humans and cats, including “remote”, “casual” and “co-dependent”. It found people whose relationship with their cat was co-dependent or like a friend had a higher emotional connection to their pet.</p> <h2>Links to heart health</h2> <p>People who own – or have owned – a cat have a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3317329/">lower risk</a> of dying from cardiovascular diseases such as stroke or heart disease. This result has been repeated in several <a href="https://journals.lww.com/jcardiovascularmedicine/fulltext/2020/05000/association_between_pet_ownership_and.3.aspx?casa_token=JmAlt8nNRAUAAAAA:NdUb0DK3DF6Fej0Vrx9t55JK-HZPmE7F1teQeDCCt3vy0Ha3aSNwZeA4KMcTVm-4ZWz1n-rEVUhIE62CUcfXhAn0sA5RQg">studies</a>.</p> <p>However a problem interpreting population studies is they only tell us about an association. This means while people with cats have lower risk of dying from cardiovascular diseases, we can’t say for sure cats are the cause.</p> <p>Cat ownership has also been associated with some positive changes in the <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0253133">gut microbiota</a>, especially in women, such as improved blood glucose control and reduced inflammation.</p> <h2>Helping mental health</h2> <p>Having cat or dog is also associated with <a href="https://www.tandfonline.com/doi/full/10.1080/08927936.2023.2182029">higher psychological well-being</a>. For people with depression, patting or playing with their cat <a href="https://www.tandfonline.com/doi/abs/10.2752/089279399787000066">has been shown</a> to reduce symptoms (although this was over a short, two-hour period and can’t be extrapolated longer-term).</p> <p>Another way to find out about the health impact of cats is qualitative research: asking people what their cats mean to them, beyond the numbers.</p> <p>When colleagues and I <a href="https://www.cabidigitallibrary.org/doi/full/10.1079/hai.2023.0013">surveyed veterans</a>, we found people more attached to their pets actually had poorer mental health scores. But their survey responses told a different story. One respondent said, “my cats are the reason I get up in the morning”.</p> <p>Another wrote:</p> <blockquote> <p>I consider my pet to be a service animal. My cat helps me to relax when I’m dealing with my anxiety, depression or when I wake during the night from the frequent nightmares I have.

How do we save ageing Australians from the heat? Greening our cities is a good start

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/claudia-baldwin-248780">Claudia Baldwin</a>, <a href="https://theconversation.com/institutions/university-of-the-sunshine-coast-1068">University of the Sunshine Coast</a>; <a href="https://theconversation.com/profiles/jason-byrne-6066">Jason Byrne</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a>, and <a href="https://theconversation.com/profiles/tony-matthews-234160">Tony Matthews</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a></em></p> <p>Heatwaves have killed more Australians than <a href="https://ama.com.au/ausmed/heatwave-health-warning">road accidents</a>, fires, floods and <a href="https://www.sciencedirect.com/science/article/pii/S1462901114000999">all other natural disasters combined</a>. Although <a href="https://theconversation.com/forget-heatwaves-our-cold-houses-are-much-more-likely-to-kill-us-83030">recent research</a> shows extreme cold is a worry in some parts of Australia, <a href="https://theconversation.com/2018-19-was-australias-hottest-summer-on-record-with-a-warm-autumn-likely-too-112616">our hottest summer on record</a> points to more heat-related deaths to come. The <a href="https://theconversation.com/the-stubborn-high-pressure-system-behind-australias-record-heatwaves-110442">record heatwaves</a> have highlighted the damaging effects of heat stress. Understandably, it’s becoming a major <a href="https://ama.com.au/ausmed/heatwaves-nation%E2%80%99s-deadliest-natural-disaster-0">public health challenge</a>.</p> <p>The risk of extreme heat events and the adverse impacts on older people has been extensively <a href="https://jech.bmj.com/content/64/9/753.short">discussed in research</a>. Remarkably, very little attention has been paid to the role of urban greenery in reducing heat stress for seniors.</p> <p>Older people are particularly at risk of heat stress. Pre-existing medical conditions and limited mobility increase their vulnerability. <a href="http://www.cmaj.ca/content/182/10/1053.short">Deaths of older people increase</a> during extreme heat events.</p> <p>The physical features of urban areas shape the capacity of older adults to engage in many activities when it’s hot. These include vegetation volume and coverage, <a href="https://theconversation.com/building-cool-cities-for-a-hot-future-57489">thermal design</a>, and the extent of shading in public areas and walkways. Increasing urban greenery may offer a way to improve older people’s comfort and social experience.</p> <h2>Ageing adds urgency to greening</h2> <p>It is expected <a href="http://www.un.org/en/sections/issues-depth/ageing/">20% of the global population</a> will be older than 60 by 2050. The figure for Australia <a href="http://www.abs.gov.au/ausstats/abs@.nsf/mediareleasesbyTopic/2CA2134677EF9D03CA257C2E0017283B?OpenDocument">is even higher</a>, at 23%. This means that by 2050 around one in four Australians will be more vulnerable to extreme heat.</p> <figure class="align-right zoomable"></figure> <p>Climate change may make the problem worse by <a href="https://www.sciencedirect.com/science/article/pii/S0749379708006867">fuelling even more extreme heat</a> events.</p> <p>Planning our urban centres to meet the needs of a <a href="https://www.aihw.gov.au/reports/older-people/older-australia-at-a-glance/contents/demographics-of-older-australians">rapidly ageing population</a> is a matter of urgency. Urban greening to reduce their vulnerability to heat stress should be central to this agenda. It can also improve people’s quality of life, reduce <a href="https://www.sciencedirect.com/science/article/abs/pii/S1353829208001172">social isolation and loneliness</a>, and ease the burden on health systems.</p> <p>An important task is matching the design of communities with the needs of an ageing population. Where older adults live and the quality of their local areas strongly influence their lived experiences. Yet <a href="https://journals.sagepub.com/doi/abs/10.1177/0885412217704649">recent research</a> found the experiences of seniors were often not accounted for in research on neighbourhood design.</p> <h2>What about aged care?</h2> <p>People face choices about where they live as they age. The common choices are to “<a href="https://theconversation.com/for-australians-to-have-the-choice-of-growing-old-at-home-here-is-what-needs-to-change-91488">age in place</a>” or to move into aged care.</p> <p>Ageing in place includes living in one’s own home or <a href="https://theconversation.com/co-housing-works-well-for-older-people-once-they-get-past-the-image-problem-79907">co-habiting with relatives or friends</a>. Around 90% of Australian seniors <a href="https://www.pc.gov.au/research/completed/housing-decisions-older-australians/housing-decisions-older-australians.pdf">choose this option</a>, with the remainder opting for aged-care facilities.</p> <p>If one in ten Australian seniors live in aged-care facilities, it is clear these should be designed to minimise heat stress. This isn’t just good for residents; it may also benefit operators by lowering health-care and electricity costs.</p> <p>While these facilities are purpose-built for older people, many in Australia were built well over a decade ago, when heat stress was not such a large concern. Many more facilities are being built now and will be into the future. Yet it is uncertain whether they are being actively designed to reduce the impacts of heat.</p> <h2>What has our research found?</h2> <p>We recently conducted a focus group to investigate this issue. Participants were senior managers from four large corporate providers of aged care in Australia. We investigated if and how providers try to minimise heat stress through design. We also sought to understand the rationales used to support these design approaches.</p> <p>Several participants reported on refurbishments that they expect will have cooling effects. Cited design approaches included green roofs and walls, as well as sensory gardens. Other expected benefits included reducing anxiety and improving the mental health of residents.</p> <p>The fact that single design interventions could produce multiple benefits improved the potential for corporate buy-in. Participants expected that increasing green space and green cover would give their facilities a competitive advantage by attracting more clients and providing a better working environment for staff.</p> <p>Participants also reported on challenges of including greening in their projects. For example, the benefits of trees were weighed against concerns about roots disrupting footpaths and becoming trip hazards. Species selection was another concern, with fears that inappropriate plants could die and undermine support for greening programs.</p> <p>Our research suggests that more can be done to make cities hospitable for older people, especially during extreme heat. Urban greening is a start. Encouraging aged-care providers to adopt green infrastructure will have benefits. But we should also consider reforms to planning systems and urban design to better protect older people who choose to age in place.<!-- Below is The Conversation's page counter tag.

Domestic Travel

Charles III will be the first king of Australia to visit our shores. He could also be the last

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/jess-carniel-99739">Jess Carniel</a>, <a href="https://theconversation.com/institutions/university-of-southern-queensland-1069">University of Southern Queensland</a></em></p> <p>King Charles III and Queen Camilla’s upcoming visit to Australia is significant for several reasons. It is Charles’ first visit since ascending to the throne – as well as the first time a British male head of state has visited Australia.</p> <p>Some observers are also wondering whether it might be one of the last royal tours, as debates about Australia potentially <a href="https://www.theguardian.com/australia-news/2024/oct/13/republican-debate-flares-ahead-of-king-charles-first-visit-to-australia-as-monarch">becoming a republic</a> are reignited.</p> <p>As the monarchy tries to “modernise” alongside growing support for republicanism, this visit will be one to watch.</p> <h2>The curse of the Antipodes?</h2> <p>As Prince of Wales, Charles had a long and successful track record of royal tours to Australia, having visited 16 times. The visits included a term attending <a href="https://www.bbc.com/news/world-australia-64113876">Geelong Grammar School</a> in 1966, as well as the <a href="https://www.townandcountrymag.com/society/tradition/g33926226/princess-diana-prince-charles-australia-royal-tour-1983-photos/">1983 tour</a> with Princess Diana that saw Australians caught up in Di-mania – and Charles reportedly <a href="https://www.abc.net.au/news/2020-11-29/princess-diana-princess-charles-australia-1983-the-crown/12914130">gripped by jealousy</a>.</p> <p>But Charles’ royal predecessors weren’t as lucky in their trips down under. His own grandfather, King George VI, <a href="https://collectionswa.net.au/items/202bce46-f056-413e-bc74-ddf4d2f8e999#:%7E:text=Planning%20for%20this%20royal%20visit,after%20her%20father's%20untimely%20death.">planned to visit</a> Australia in the late 1940s with Queen Elizabeth and Princess Margaret, but the tour was postponed due to his poor health. While he had previously visited as the <a href="https://collections.museumsvictoria.com.au/articles/2053#:%7E:text=They%20had%20two%20daughters%2C%20Elizabeth,Canberra%20on%209%20May%201927.">Duke of York</a>, George VI never made it here as king.</p> <p>The very first royal visit to Australia – Prince Alfred’s <a href="https://www.nma.gov.au/defining-moments/resources/first-royal-visit">1867 tour</a> – had all appearance of being cursed. One of his crew members drowned during the first stop in South Australia. Several more people died in a major fire accident and a Catholic-Protestant skirmish in Melbourne.</p> <p>Most memorably – certainly for Alfred – was <a href="https://theconversation.com/royal-visits-to-australia-can-be-disaster-magnets-in-the-first-one-the-prince-barely-made-it-out-alive-233103">an assassination attempt</a> on the prince in Sydney. This, interestingly, is an experience King Charles has also had.</p> <p>During Charles’ 1994 visit, student protester David Kang fired blanks from a starter pistol in protest of Australia’s treatment of Cambodian refugees. The then Prince of Wales wasn’t harmed and Kang went on to <a href="https://www.smh.com.au/national/he-shot-at-a-prince-now-hes-a-barrister-20050206-gdkmyp.html">become a barrister</a>.</p> <p>For non-British royals, however, Sydney has been a lucky location. King Frederick X’s decidedly modern romance <a href="https://www.womensweekly.com.au/royals/princess-mary/crown-princess-mary-crown-prince-frederik-love-story/">with Tasmania-born Queen Mary</a> famously began when they met at a bar during the Sydney Olympics in 2000.</p> <h2>Prince or king – does it matter?</h2> <p>This will be Charles’ seventeenth visit to Australia, but his first as reigning monarch. This means he is visiting not on behalf of the head of state, but as the head of state.</p> <p>The royal couple’s planned <a href="https://www.royal.uk/news-and-activity/2024-09-10/the-king-and-queen-will-visit-australia-and-samoa">Australian engagements</a> are as strategic as they are symbolic. They reflect carefully curated and ostensibly “non-political” issues such as environmental sustainability, cancer research and family violence.</p> <p>The visit also includes a meeting with Indigenous representatives. Notably, it is the first royal tour <a href="https://www.smh.com.au/politics/federal/royal-walkabout-shelved-due-to-cultural-sensitivities-20240911-p5k9n1.html">to not use the term “walkabout”</a> to describe public meet-and-greets, as this term had been criticised as cultural appropriation.</p> <p>It seems Charles’ modernised monarchy is seeking to distance itself from overtly colonial language – as much as a foreign monarchy can, anyway. The king has yet to respond to Indigenous leaders <a href="https://theconversation.com/should-king-charles-apologise-for-the-genocide-of-first-nations-people-when-he-visits-australia-239092">calling for an apology</a> for British colonisers’ genocides of First Nations peoples.</p> <p>Although the Australian media has focused on the stops in Canberra and Sydney, the main purpose of the tour is for the king to attend the Commonwealth Heads of Government Meeting <a href="https://samoachogm2024.ws/">in Samoa</a> between October 21 and 26.</p> <p>It is the first time the meeting will be hosted by a Pacific Island state. The talks are an important opportunity for the king to highlight issues such as climate change, to which small island states in the Pacific <a href="https://www.csiro.au/en/research/environmental-impacts/climate-change/pacific-climate-change-info">are particularly vulnerable</a>.</p> <h2>Are people happy about the visit?</h2> <p>All six state premiers have declined their invitations to meet the king at his welcome reception in Canberra, citing other commitments. Their excuses might be genuine in some cases. For example, Queensland Premier Steven Miles is in the last few weeks of an election campaign.</p> <p>However, critics from the monarchist camp have viewed the move as <a href="https://www.politico.eu/article/king-charles-iii-snubbed-australia-state-leaders-visit-insult-uk/">a political response</a> to debates over whether Australia should remain a constitutional monarchy with the king as its head of state.</p> <p>A <a href="https://au.yougov.com/politics/articles/46044-one-year-king-charles-reign-where-do-australian-at">YouGov Australia poll</a> published on the first anniversary of Charles’s ascension showed Australians are divided on republicanism. While 32% want to become a republic “as soon as possible”, 35% preferred to remain a constitutional monarchy and 12% wanted to become a republic after the king’s death. The remaining respondents didn’t know.</p> <p>Notably, the poll found republican sentiment had increased since Queen Elizabeth II’s death in September 2022.</p> <p>The Albanese government established an assistant minister for the republic upon entering office in 2022 (although the portfolio was abolished with <a href="https://www.theguardian.com/australia-news/article/2024/jul/29/albaneses-new-lineup-signposts-labors-areas-of-greatest-weakness-and-effectively-concede-he-made-mistakes">this year’s reshuffle</a>). Upon taking the role, assistant minister Matt Thistlethwaite <a href="https://www.theguardian.com/australia-news/2022/jun/01/minister-republic-twilight-queen-reign-good-opportunity-next-for-australia">suggested</a> the “twilight of [Queen Elizabeth’s] reign” presented “a good opportunity for a serious discussion about what comes next for Australia”.</p> <p>Charles doesn’t seem to be taking all this too personally. In a letter responding to the Australian Republican Movement in March this year, his private secretary said the king <a href="https://www.theguardian.com/australia-news/2024/oct/13/republican-debate-flares-ahead-of-king-charles-first-visit-to-australia-as-monarch">viewed this</a> as “a matter for the Australian public to decide”.</p> <p>The royal tour and the meeting in Samoa will be important opportunities for the monarchy to connect with Australia and other Commonwealth nations.</p> <p>By presenting itself as a modern institution engaged with contemporary issues such as climate change, the monarchy will also have to engage with the possibility of new political identities for its former colonies.<!-- Below is The Conversation's page counter tag.

Eight simple changes to our neighbourhoods can help us age well

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/jerome-n-rachele-251972">Jerome N Rachele</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a>; <a href="https://theconversation.com/profiles/james-f-sallis-407885">James F Sallis</a>, <a href="https://theconversation.com/institutions/university-of-california-san-diego-1314">University of California, San Diego</a>, and <a href="https://theconversation.com/profiles/venurs-loh-118864">Venurs Loh</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a></em></p> <p>Where we live can play a big part in ageing well, largely because of the links between physical activity and wellbeing. <a href="https://www.ahuri.edu.au/__data/assets/pdf_file/0012/2181/AHURI_Final_Report_No214_Downsizing-amongst-older-Australians.pdf">Research shows</a> that two-thirds of Australians prefer to age in place. That is, we want to live independently in our homes for as long as we can. Our neighbourhoods and their design can then improve or hinder our ability to get out of the house and be physically active.</p> <p>The rapid ageing of Australia’s population only adds to the importance of neighbourhood design. In 2016, 15% of Australians were aged 65 or older. That proportion is <a href="https://www.aihw.gov.au/reports-statistics/population-groups/older-people/overview">projected to double</a> by 2056.</p> <p>These trends present several <a href="https://www.aihw.gov.au/reports-statistics/population-groups/older-people/reports">social and economic challenges</a>, particularly for the health sector. Designing neighbourhoods in ways that promote physical activity can help overcome these challenges.</p> <h2>Eight simple steps</h2> <p>The following is a short list of <a href="https://ijbnpa.biomedcentral.com/articles/10.1186/s12966-017-0471-5">evidence-based steps</a> local and state governments can take to assist older people to be physically active. These involve minor but effective changes to neighbourhood design.</p> <p><strong>Improve footpaths:</strong> Research indicates that older people have a <a href="https://theconversation.com/why-older-people-get-osteoporosis-and-have-falls-68145">higher risk of falls</a>. Ensuring footpaths are level and crack-free, and free from obstructions, will encourage walking among older people – especially those with a disability.</p> <p><strong>Connected pedestrian networks:</strong> Introducing footpaths at the end of no-through-roads and across long street blocks reduces walking distances to destinations. This makes walking a more viable option.</p> <p><strong>Slowing traffic in high-pedestrian areas:</strong> Slowing traffic <a href="https://www.heartfoundation.org.au/images/uploads/publications/Safe-Speed-Evidence-Report.pdf">improves safety</a> by reducing the risk of a collision. It also reduces the risk of <a href="https://www.ncbi.nlm.nih.gov/pubmed/28557669">death and serious injury</a> in the event of a collision.</p> <p><strong>Age-friendly street crossings:</strong> Installing longer pedestrian crossing light sequences gives older pedestrians <a href="https://academic.oup.com/ageing/article/41/5/690/47318/Most-older-pedestrians-are-unable-to-cross-the">more time to cross</a>, and installing refuge islands means those who walk more slowly can cross the street in two stages.</p> <p><strong>Disabled access at public transport:</strong> Although a form of motorised transport, public transport users undertake more incidental physical activity compared with car users.

We tend to underestimate our future expenses – here’s one way to prevent that

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/ray-charles-chuck-howard-1361224">Ray Charles "Chuck" Howard</a>, <a href="https://theconversation.com/institutions/texas-aandm-university-1672">Texas A&amp;M University</a>; <a href="https://theconversation.com/profiles/abigail-sussman-227057">Abigail Sussman</a>, <a href="https://theconversation.com/institutions/university-of-chicago-952">University of Chicago</a>; <a href="https://theconversation.com/profiles/david-j-hardisty-753777">David J.

However, when prompted to think about unexpected spending in addition to typical expenses, people made much more accurate predictions.</p> <p>These are the main findings of a series of <a href="https://doi.org/10.1177%2F00222437211068025">studies and experiments that we conducted</a> and which have just been published in the <a href="https://journals.sagepub.com/home/mrj">Journal of Marketing Research</a>.</p> <p>In our first study, we began by asking 187 members of a Canadian credit union to predict their weekly spending for the next five weeks. Then, at the end of each week, we asked them how much they actually spent.</p> <p>For the first four weeks, people underpredicted their weekly spending by about $100 per week or $400 for the month.</p> <p>In the study’s fifth and final week, we ran an experiment to see if we could improve people’s prediction accuracy.</p> <p>Specifically, we randomly assigned participants to one of two groups. In group one, participants estimated their spending for the next week just as they had done in previous weeks. These folks once again significantly underpredicted their spending.</p> <p>In group two, participants were asked to think of three reasons why their spending for the next week might be different than usual before making their estimate. This led them to make higher and much more accurate predictions – coming within just $7 of what they actually spent.</p> <p>Importantly, participants in each group spent roughly the same amount of money that week, on average. The only difference between the two groups was whether they accurately predicted that amount.</p> <p><iframe id="WlDv3" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/WlDv3/3/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe></p> <p>Next, we conducted nine experiments to better understand why people underpredict their spending and whether being prompted to think of unusual expenses helps improve accuracy. In all, over 5,800 people participated in these experiments, including a representative sample of U.S. residents.</p> <p>These experiments revealed two important insights.</p> <p>First, people primarily base their spending predictions on typical expenses like groceries, gasoline and rent. They usually fail to account for irregular – though still common – expenses like car repairs, last-minute concert tickets or one-off health care bills. This is what leads to underprediction.</p> <p>Second, prompting people to think of irregular expenses in addition to typical expenses helps them to make more accurate spending predictions. In our studies, people did not factor in atypical expenses unless we asked them to do so.</p> <h2>Why it matters</h2> <p>Helping people improve the accuracy of their spending predictions could help them improve their financial well-being.</p> <p>Underpredicting expenses can be costly. For example, 12 million Americans <a href="https://www.pewtrusts.org/en/research-and-analysis/reports/2012/07/19/who-borrows-where-they-borrow-and-why">borrow a total of more than $7 billion</a> in payday loans each year because they can’t meet their monthly expenses. These loans typically have extremely high interest rates – <a href="https://www.pewtrusts.org/en/research-and-analysis/data-visualizations/2022/how-well-does-your-state-protect-payday-loan-borrowers">more than 250% in some states</a>.</p> <p>Payday loans also come due in full so quickly that around three in four borrowers <a href="https://www.pewtrusts.org/en/research-and-analysis/reports/2012/07/19/who-borrows-where-they-borrow-and-why">end up borrowing again</a> to pay off the original loan.</p> <p>If consumers could better anticipate how much money they will spend in the future, it might help motivate them to spend less and save more in the present.</p> <p>In fact, one of our studies shows that our suggested prediction strategy <a href="https://doi.org/10.1177/0022243721106802">not only boosted spending estimates</a>, it also increased intentions to save.</p> <h2>What’s next</h2> <p>Members of our research team are currently investigating if, when and why underpredicting one’s expenses may be beneficial. For example, if a person sets an optimistically low budget and actively tracks their spending against it, does that help them reduce their spending?</p> <p>We are also investigating whether people who work in the gig economy show a corresponding tendency to mispredict their future income.<!-- Below is The Conversation's page counter tag.

Why are we seeing more pandemics? Our impact on the planet has a lot to do with it

In the Middle Ages we had the Black Death (plague), and after the first world war we had the Spanish flu. Tens of millions of people <a href="https://assets.cureus.com/uploads/review_article/pdf/69273/20211019-25919-an4y6h.pdf">died from these diseases</a>.</p> <p>Then science began to <a href="https://www.frontiersin.org/journals/immunology/articles/10.3389/fimmu.2011.00053/full">get the upper hand</a>, with vaccination eradicating smallpox, and polio nearly so. Antibiotics became available to treat bacterial infections, and more recently antivirals as well.</p> <p>But in recent years and decades pandemics <a href="https://assets.cureus.com/uploads/review_article/pdf/69273/20211019-25919-an4y6h.pdf">seem to be returning</a>. In the 1980s we had HIV/AIDS, then several flu pandemics, SARS, and now COVID (no, COVID isn’t over).</p> <p>So why is this happening, and is there anything we can do to avert future pandemics?</p> <h2>Unbalanced ecosystems</h2> <p>Healthy, stable ecosystems provide services that keep us healthy, such as supplying food and clean water, producing oxygen, and making green spaces available for our <a href="https://www.millenniumassessment.org/documents/document.356.aspx.pdf">recreation and wellbeing</a>.</p> <p>Another key service ecosystems provide is disease regulation. When nature is in balance – with predators controlling herbivore populations, and herbivores controlling plant growth – it’s more difficult for pathogens to emerge in a way that causes pandemics.</p> <p>But when human activities <a href="https://books.google.com.au/books?hl=en&amp;lr=&amp;id=rWozz12K1aUC&amp;oi=fnd&amp;pg=PP15&amp;dq=planetary+overload&amp;ots=c9mWuESUXN&amp;sig=-1iP3uSOWazvC2OFLk4vginWbQQ&amp;redir_esc=y#v=onepage&amp;q=planetary%20overload&amp;f=false">disrupt and unbalance ecosystems</a> – such as by way of climate change and biodiversity loss – <a href="https://academic.oup.com/bioscience/article/58/8/756/381265">things go wrong</a>.</p> <p>For example, climate change affects the number and distribution of plants and animals. Mosquitoes that carry diseases can move from the tropics into what used to be temperate climates as the planet warms, and may infect more people in the months that are normally disease free.</p> <p>We’ve studied the relationship between weather and dengue fever transmission in China, and <a href="https://pubmed.ncbi.nlm.nih.gov/27883970/">our findings</a> support the same conclusion reached by <a href="https://journals.plos.org/plosntds/article?id=10.1371/journal.pntd.0008118">many other studies</a>: climate change is likely to put more people at risk of dengue.</p> <p>Biodiversity loss can have similar effects by disrupting food chains. When ranchers cleared forests in <a href="https://www.mdpi.com/1999-4915/6/5/1911">South America</a> for their cattle to graze in the first half of the 20th century, tiny forest-dwelling, blood-feeding vampire bats suddenly had a smörgåsbord of large sedentary animals to feed on.</p> <p>While vampire bats had previously been kept in check by the limited availability of food and the presence of predators in the balanced <a href="https://cir.nii.ac.jp/crid/1130000797648461952">forest ecosystem</a>, numbers of this species exploded in South America.</p> <p>These bats carry the rabies virus, which causes <a href="https://www.who.int/news-room/fact-sheets/detail/rabies">lethal brain infections</a> in people who are bitten. Although the number of deaths from bat-borne rabies has now fallen dramatically due to vaccination programs in South America, rabies caused by bites from other animals still <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3168224/">poses a global threat</a>.</p> <p>As urban and agricultural development impinges on natural ecosystems, there are increasing opportunities for humans and domestic animals to become infected with pathogens that would normally only be seen in wildlife – particularly when people hunt and eat animals from the wild.</p> <p>The HIV virus, for example, <a href="https://www.tandfonline.com/doi/abs/10.1076/jmep.27.2.163.2992">first entered human populations</a> from apes that were slaughtered for food in Africa, and then spread globally through travel and trade.</p> <p>Meanwhile, bats are thought to be <a href="https://www.sciencedirect.com/science/article/pii/S0006291X20319434">the original reservoir</a> for the virus that caused the COVID pandemic, which has killed more than <a href="https://www.worldometers.info/coronavirus/">7 million people</a> to date.</p> <p>Ultimately, until we effectively address the unsustainable impact we are having on our planet, pandemics will continue to occur.</p> <h2>Targeting the ultimate causes</h2> <p>Factors such as climate change, biodiversity loss and other global challenges are the ultimate (high level) cause of pandemics. Meanwhile, increased contact between humans, domestic animals and wildlife is the proximate (immediate) cause.</p> <p>In the case of HIV, while direct contact with the infected blood of apes was the proximate cause, the apes were only being slaughtered because large numbers of very poor people were hungry – an ultimate cause.</p> <p>The distinction between <a href="https://link.springer.com/article/10.1007/BF02207379">ultimate causes and proximate causes</a> is important, because we often deal only with proximate causes. For example, people may smoke because of stress or social pressure (ultimate causes of getting lung cancer), but it’s the toxins in the smoke that cause cancer (proximate cause).</p> <p>Generally, health services are only concerned with stopping people from smoking – and with treating the illness that results – not with removing the drivers that lead them to smoke in the first place.</p> <p>Similarly, we address pandemics with lockdowns, mask wearing, social distancing and vaccinations – all measures which seek to stop the spread of the virus. But we pay less attention to addressing the ultimate causes of pandemics – until perhaps very recently.</p> <h2>A planetary health approach</h2> <p>There’s a growing awareness of the importance of adopting a “planetary health” approach to improve human health. This <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(15)60901-1/fulltext?nr_email_referer=1">concept</a> is based on the understanding that human health and human civilisation depend on flourishing natural systems, and the wise stewardship of those natural systems.</p> <p>With this approach, ultimate drivers like climate change and biodiversity loss would be prioritised in preventing future pandemics, at the same time as working with experts from many different disciplines to deal with the proximate causes, thereby reducing the risk overall.</p> <p>The planetary health approach has the benefit of improving both the health of the environment and human health concurrently. We are heartened by the increased uptake of teaching planetary health concepts across the environmental sciences, humanities and health sciences in many universities.</p> <p>As climate change, biodiversity loss, population displacements, travel and trade continue to increase the risk of disease outbreaks, it’s vital that the planetary stewards of the future have a better understanding of how to tackle the ultimate causes that drive pandemics.</p> <p><em>This article is the first in a series on the next pandemic.</em><!-- Below is The Conversation's page counter tag.

Does intermittent fasting increase or decrease our risk of cancer?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/amali-cooray-1482458">Amali Cooray</a>, <a href="https://theconversation.com/institutions/wehi-walter-and-eliza-hall-institute-of-medical-research-822"><em>WEHI (Walter and Eliza Hall Institute of Medical Research)</em> </a></em></p> <p>Research over the years has suggested intermittent fasting has the potential to improve our health and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3946160/">reduce the likelihood</a> of developing cancer.</p> <p>So what should we make of a <a href="https://www.nature.com/articles/s41586-024-07840-z">new study</a> in mice suggesting fasting increases the risk of cancer?</p> <h2>What is intermittent fasting?</h2> <p>Intermittent fasting means switching between times of eating and not eating. Unlike traditional diets that focus on <em>what</em> to eat, this approach focuses on <em>when</em> to eat.</p> <p>There are lots of commonly used <a href="https://dietitiansaustralia.org.au/health-advice/intermittent-fasting">intermittent fasting schedules</a>. The 16/8 plan means you only eat within an eight-hour window, then fast for the remaining 16 hours. Another popular option is the 5:2 diet, where you eat normally for five days then restrict calories for two days.</p> <p>In Australia, poor diet contributes to <a href="https://www.health.gov.au/topics/food-and-nutrition/what-were-doing">7% of all cases of disease</a>, including coronary heart disease, stroke, type 2 diabetes, and cancers of the bowel and lung. Globally, poor diet is linked to <a href="https://www.thelancet.com/article/S0140-6736(19)30041-8/fulltext">22% of deaths</a> in adults over the age of 25.</p> <p>Intermittent fasting has gained a lot of attention in recent years for its potential health benefits. Fasting <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/metabolism">influences metabolism</a>, which is how your body processes food and energy. It can affect how the body absorbs nutrients from food and burns energy from sugar and fat.</p> <h2>What did the new study find?</h2> <p>The <a href="https://www.nature.com/articles/s41586-024-07840-z">new study</a>, published in Nature, found when mice ate again after fasting, their <a href="https://www.nature.com/articles/s12276-024-01179-1">gut stem cells</a>, which help repair the intestine, became more active. The stem cells were better at regenerating compared with those of mice who were either totally fasting or eating normally.</p> <p>This suggests the body might be better at healing itself when eating after fasting.</p> <p>However, this could also have a downside. If there are <a href="https://www.cancer.gov/about-cancer/causes-prevention/genetics/genetic-changes-infographic">genetic mutations</a> present, the burst of stem cell-driven regeneration after eating again might make it easier for cancer to develop.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4027058/">Polyamines</a> – small molecules important for cell growth – drive this regeneration after refeeding. These polyamines can be produced by the body, influenced by diet, or come from gut bacteria.</p> <p>The findings suggest that while fasting and refeeding can improve stem cell function and regeneration, there might be a tradeoff with an increased risk of cancer, especially if fasting and refeeding cycles are repeated over time.</p> <p>While this has been shown in mice, the link between intermittent fasting and cancer risk in humans is more complicated and not yet fully understood.</p> <h2>What has other research found?</h2> <p><a href="https://www.annualreviews.org/content/journals/10.1146/annurev-nutr-071816-064634">Studies in animals</a> have found intermittent fasting can help with weight loss, improve blood pressure and blood sugar levels, and subsequently <a href="https://pubmed.ncbi.nlm.nih.gov/27810402/">reduce the risks</a> of diabetes and heart disease.</p> <p>Research in humans <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2811116">suggests</a> intermittent fasting can reduce body weight, improve <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9361187/">metabolic health</a>, reduce inflammation, and enhance <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3946160/">cellular repair processes</a>, which remove damaged cells that could potentially turn cancerous.</p> <p>However, other studies warn that the benefits of intermittent fasting are the same as what can be achieved through <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2623528">calorie restriction</a>, and that there <a href="https://www.sciencedirect.com/science/article/pii/S2161831322007542">isn’t enough evidence</a> to confirm it reduces cancer risk in humans.</p> <h2>What about in people with cancer?</h2> <p>In studies of people who have cancer, fasting has been <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2815756/">reported to</a> protect against the side effects of chemotherapy and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7311547/">improve the effectiveness</a> of cancer treatments, while decreasing damage to healthy cells.</p> <p>Prolonged fasting in some patients who have cancer has been shown to be safe and <a href="https://pubmed.ncbi.nlm.nih.gov/34383300/">may potentially</a> be able to decrease tumour growth.</p> <p>On the other hand, some experts advise caution. Studies in mice show intermittent fasting could <a href="https://www.nature.com/articles/s41423-023-01033-w">weaken the immune system</a> and make the body less able to fight infection, potentially leading to worse health outcomes in people who are unwell. However, there is <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8757987/">currently no evidence</a> that fasting increases the risk of bacterial infections in humans.</p> <h2>So is it OK to try intermittent fasting?</h2> <p>The current view on intermittent fasting is that it can be beneficial, but experts agree more research is needed. Short-term benefits such as weight loss and better overall health are well supported. But we don’t fully understand the long-term effects, especially when it comes to cancer risk and other immune-related issues.</p> <p>Since there are many different methods of intermittent fasting and people react to them differently, it’s hard to <a href="https://www.nature.com/articles/s41423-023-01033-w">give advice that works for everyone</a>. And because most people who participated in the studies were overweight, or had diabetes or other health problems, we don’t know how the results apply to the broader population.</p> <p>For healthy people, intermittent fasting is generally considered safe. But it’s <a href="https://dietitiansaustralia.org.au/health-advice/intermittent-fasting">not suitable for everyone</a>, particularly those with certain medical conditions, pregnant or breastfeeding women, and people with a history of eating disorders.

Food and exercise can treat depression as well as a psychologist, our study found. And it’s cheaper

But they have never been directly compared with psychological therapies – until now.</p> <p>Amid a nation-wide <a href="https://www.health.gov.au/sites/default/files/2023-10/national-mental-health-workforce-strategy-2022-2032.pdf">shortage</a> of mental health professionals, our research points to a potential solution. As we found lifestyle counselling was as effective as psychological therapy, our findings suggest dietitians and exercise physiologists may one day play a role in managing depression.</p> <h2>What did our study measure?</h2> <p>During the prolonged COVID lockdowns, Victorians’ distress levels were <a href="https://onlinelibrary.wiley.com/doi/full/10.5694/mja2.50831">high and widespread</a>. Face-to-face mental health services were limited.</p> <p>Our trial targeted people living in Victoria with elevated distress, meaning at least mild depression but not necessarily a diagnosed mental disorder. Typical symptoms included feeling down, hopeless, irritable or tearful.</p> <p>We partnered with our <a href="https://www.barwonhealth.org.au/mhdas/">local mental health service</a> to recruit 182 adults and provided group-based sessions on Zoom. All participants took part in up to six sessions over eight weeks, facilitated by health professionals.</p> <p>Half were randomly assigned to participate in a program co-facilitated by an accredited practising dietitian and an exercise physiologist. That group – called the lifestyle program – developed nutrition and movement goals:</p> <ul> <li>eating a wide variety of foods</li> <li>choosing high-fibre plant foods</li> <li>including high quality fats</li> <li>limiting discretionary foods, such as those high in saturated fats and added sugars</li> <li>doing enjoyable physical activity.</li> </ul> <p>The second group took part in psychotherapy sessions convened by two psychologists. The psychotherapy program used cognitive behavioural therapy (CBT), the gold standard for treating depression in <a href="https://jamanetwork.com/journals/jamapsychiatry/article-abstract/2730724">groups and when delivered remotely</a>.</p> <p>In both groups, participants could continue existing treatments (such as taking antidepressant medication). We gave both groups <a href="https://link.springer.com/article/10.1186/s12888-022-03840-3">workbooks and hampers</a>. The lifestyle group received a food hamper, while the psychotherapy group received items such as a colouring book, stress ball and head massager.</p> <h2>Lifestyle therapies just as effective</h2> <p>We found similar results in each program.</p> <p>At the trial’s beginning we gave each participant a score based on their self-reported mental health. We measured them again at the end of the program.</p> <p>Over eight weeks, those scores showed symptoms of depression reduced for participants in the lifestyle program (42%) and the psychotherapy program (37%). That difference was not statistically or clinically meaningful so we could conclude both treatments were as good as each other.</p> <p>There were some differences between groups. People in the lifestyle program improved their diet, while those in the psychotherapy program felt they had increased their social support – meaning how connected they felt to other people – compared to at the start of the treatment.</p> <p>Participants in both programs increased their physical activity. While this was expected for those in the lifestyle program, it was less expected for those in the psychotherapy program. It may be because they knew they were enrolled in a research study about lifestyle and subconsciously changed their activity patterns, or it could be a positive by-product of doing psychotherapy.</p> <p>There was also not much difference in cost. The lifestyle program was slightly cheaper to deliver: A$482 per participant, versus $503 for psychotherapy. That’s because hourly rates differ between dietitians and exercise physiologists, and psychologists.</p> <h2>What does this mean for mental health workforce shortages?</h2> <p>Demand for mental health services is increasing in Australia, while at the same time the workforce <a href="https://www.health.gov.au/sites/default/files/2023-10/national-mental-health-workforce-strategy-2022-2032.pdf">faces worsening nation-wide shortages</a>.</p> <p>Psychologists, who provide <a href="https://www.aihw.gov.au/getmedia/6b19e493-0ebe-420f-a9a3-e48b26aace9f/aihw-aus-249-ib.pdf?v=20240628145747&amp;inline=true">about half</a> of all mental health services, can have long wait times. Our results suggest that, with the appropriate training and guidelines, allied health professionals who specialise in diet and exercise could help address this gap.</p> <p>Lifestyle therapies can be combined with psychology sessions for multi-disciplinary care. But diet and exercise therapies could prove particularly effective for those on waitlists to see a psychologists, who may be receiving no other professional support while they wait.</p> <p>Many dietitians and exercise physiologists already have advanced skills and expertise in motivating behaviour change. Most accredited practising dietitians are trained in managing <a href="https://link.springer.com/content/pdf/10.1007/978-3-030-67929-3_38-1.pdf">eating disorders</a> or <a href="https://www.nature.com/articles/s41572-020-0200-2">gastrointestinal conditions</a>, which commonly overlap with depression.</p> <p>There is also a cost argument. It is <a href="https://journals.sagepub.com/doi/full/10.1177/1355819616668202">overall cheaper</a> to train a dietitian ($153,039) than a psychologist ($189,063) – and it takes less time.</p> <h2>Potential barriers</h2> <p>Australians with chronic conditions (such as diabetes) can access subsidised dietitian and exercise physiologist appointments under various Medicare treatment plans. Those with eating disorders can also access subsidised dietitian appointments. But mental health care plans for people with depression do not support subsidised sessions with dietitians or exercise physiologists, despite <a href="https://dietitiansaustralia.org.au/sites/default/files/2024-04/Dietitians%20Australia%20Mental%20Health%20Evidence%20Brief%202024.pdf">peak bodies</a> urging them to do so.</p> <p>Increased training, upskilling and Medicare subsidies would be needed to support dietitians and exercise physiologists to be involved in treating mental health issues.</p> <p><a href="https://foodandmoodcentre.com.au/academy">Our training</a> and clinical <a href="https://www.tandfonline.com/doi/full/10.1080/15622975.2022.2112074">guidelines</a> are intended to help clinicians practising lifestyle-based mental health care within their scope of practice (activities a health care provider can undertake).</p> <h2>Future directions</h2> <p>Our trial took place during COVID lockdowns and examined people with at least mild symptoms of depression who did not necessarily have a mental disorder.

Our research shows 4 in 10 Australians in aged care are malnourished. What can we do about it?

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/jonathan-foo-1551045">Jonathan Foo</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> and <a href="https://theconversation.com/profiles/marie-claire-oshea-1373994">Marie-Claire O'Shea</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a></em></p> <p>In the next 40 years <a href="https://treasury.gov.au/sites/default/files/2023-08/p2023-435150-fs.pdf">in Australia</a>, it’s predicted the number of Australians aged 65 and over will more than double, while the number of people aged 85 and over will more than triple.</p> <p>If you’re not really interested in aged care, you should be. Given these figures, you will almost certainly be engaging with aged care services at some stage – either for yourself, or supporting family members or friends seeking aged care.</p> <p>One service you are likely to encounter is residential aged care homes. In the past few years this sector has been under more scrutiny than ever before. Changes to legislation, workforce and funding are in motion. But the question remains as to whether these changes can happen fast enough to meet our ageing population’s needs.</p> <p>One area of need not being adequately met at present is nutrition. In a <a href="https://www.mdpi.com/2227-9032/12/13/1296">new study</a>, we’ve found four in ten older Australians living in residential aged care are not receiving enough of the right types of nutrients, resulting in loss of weight and muscle. This is known as malnutrition.</p> <h2>Good nutrition is essential for healthy ageing</h2> <p>Malnutrition in older people is <a href="https://www.agedcarequality.gov.au/providers/food-nutrition-dining/why-meals-matter">associated with</a> poorer overall health, such as increased risk of falls and infections. This can accelerate loss of independence for older people, including the need for extra assistance with basic activities such as bathing and dressing.</p> <p>Older people are at increased risk of <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(22)02612-5/abstract">malnutrition</a> for a range of reasons. These can include decreased appetite, difficulties with chewing and swallowing, and the presence of other chronic diseases such as Parkinson’s disease or dementia.</p> <p>Importantly, ensuring adequate nutrition is about more than just offering healthy foods. We eat not only to meet nutritional requirements, but for enjoyment and socialisation. We each have different preferences around what we want to eat, when and with whom.</p> <p>Food provision poses a challenge for residential aged care providers who must navigate the range of residents’ preferences together with dietary restrictions and texture modifications. This must also be balanced against the practicalities of having the right number of appropriately trained kitchen and mealtime assistance staff, and working within funding constraints.</p> <p>Understanding more about who is malnourished in aged care can help providers better address this problem.</p> <h2>Malnutrition is an ongoing problem in aged care</h2> <p>We looked at more than 700 aged care residents in New South Wales, Queensland and South Australia. We assessed participants for malnutrition using a screening tool that collects data on medical history and dietary intake, and includes a physical examination of muscle and fat.</p> <p>We found 40% were malnourished, including 6% who were severely malnourished. This likely underestimates the true rate of malnutrition, as residents with dementia were excluded. International <a href="https://www.mdpi.com/2072-6643/15/13/2927">studies</a> have shown an average of 80% of aged care residents with dementia are malnourished or at risk of developing malnutrition.</p> <p>Our findings are broadly in line with a synthesis of <a href="https://www.sciencedirect.com/science/article/pii/S0378512219301148">38 international studies</a>, which reported an average malnutrition rate in residential aged care of 52%.</p> <p>In Australia, malnutrition was highlighted as <a href="https://www.royalcommission.gov.au/aged-care">a priority</a> for immediate attention in the 2021 Royal Commission into Aged Care Quality and Safety. Its report cited <a href="https://www.cambridge.org/core/journals/british-journal-of-nutrition/article/dairy-food-supplementation-may-reduce-malnutrition-risk-in-institutionalised-elderly/52E93ADD586C634A3913A2AFE9D07847">an Australian study</a> of 215 residents, published in 2017, which found 68% were malnourished or at risk of malnutrition.</p> <p>It’s difficult to directly compare malnutrition rates between studies due to differences in diagnostic measurements. But it’s clear malnutrition is an ongoing challenge in aged care.</p> <h2>What can we do about it?</h2> <p>Since the royal commission, we’ve seen the strengthening of the <a href="https://www.agedcarequality.gov.au/providers/quality-standards/strengthened-quality-standards">quality standards</a> to be included in the new Aged Care Act, anticipated to be introduced to parliament in 2025.</p> <p>The strengthened quality standards provide an important framework to guide action by aged care providers on malnutrition. Key requirements include partnering with residents to design food options, regular assessment and reassessment of resident nutrition requirements, developing systems to monitor and improve satisfaction with food, designing pleasant dining environments, and providing staff with the training they need to achieve all of the above.</p> <p>However, achieving these standards will require investment of money and time. At the moment, <a href="https://kpmg.com/au/en/home/insights/2023/09/australian-aged-care-sector-analysis.html">64% of residential aged care providers</a> in Australia are operating at a financial loss. While we know carers and facility managers want to provide the best care possible, it’s difficult to achieve this when contending with underlying financial problems.</p> <p>As such, our teams at Monash and Griffith universities are focusing on strategies that minimise the burden on staff and providers.</p> <p>We are working on automating malnutrition screening. Current tools take 10–15 minutes and should be used when a new resident moves into an aged care home and regularly during their stay. But anecdotal evidence suggests providers lack the staff and funding needed to routinely carry out this screening.</p> <p>Instead, we aim to use existing data from aged care providers, including quarterly reports from the <a href="https://www.health.gov.au/our-work/qi-program">National Aged Care Mandatory Quality Indicator Program</a>, to detect malnutrition automatically. This will allow staff to focus more on care.</p> <p>Given the complexity of malnutrition, it’s likely that addressing the issue at a national scale will take some time. In the short term, for those with loved ones in aged care homes, we encourage you to be actively involved in their care, including noticing and speaking up if you think more can be done to optimise their nutrition.<!-- Below is The Conversation's page counter tag.

But while they enrich our lives in countless ways, we often fail to consider the potential impact of screen time on our cognitive abilities.</p> <p>In a <a href="https://link.springer.com/article/10.1007/s11065-023-09612-4">new meta-analysis</a> of dozens of earlier studies, we’ve found a clear link between disordered screen use and lower cognitive functioning.</p> <p>The findings suggest we should exercise caution before advocating for more screen time, and before introducing screens into even more aspects of daily life.</p> <h2>Young people’s screen time is increasing</h2> <p>In 2020, a UNSW Gonski Institute for Education report <a href="https://www.gie.unsw.edu.au/sites/default/files/documents/UNSW%20GIE%20GUD%20Phase%201%20Technical%20Report%20MAR20%20v2.pdf">noted a concerning statistic</a>: about 84% of Australian educators believe digital technologies are distracting in a learning environment.</p> <p>And according to the ABC, a recent Beyond Blue <a href="https://www.abc.net.au/news/2023-09-18/mental-health-depression-anxiety-support-coming-for-schools/102831464">survey</a> of Australian teachers identified excessive screen time as the second-most significant challenge for young people, just behind mental health issues.</p> <p>Despite mounting concerns, more than half of Australian schools have embraced a “<a href="https://www.linewize.io/anz/blog/the-rise-of-byod-in-australian-schools">bring your own device</a>” policy. Students are spending more time online than <a href="https://read.oecd-ilibrary.org/education/students-computers-and-learning_9789264239555-en#page46">ever before</a> and starting at increasingly younger ages. A 2021 report by <a href="https://www.commonsensemedia.org/sites/default/files/research/report/8-18-census-integrated-report-final-web_0.pdf">Common Sense Media</a> estimated tweens spend an average of 5 hours and 33 minutes using screen-based entertainment each day, while teenagers devote a whopping 8 hours and 39 minutes.</p> <p>A surge in screen use has led to some individuals, including children, adolescents and adults, developing screen-related addictions.

This is a broad category of problematic behaviours that may include screen dependency, and persisting with screen use even when it’s harmful.</p> <p>We conducted a meta-analysis of 34 studies that explored various forms of screen use (including gaming, internet browsing, smartphone use and social media use) and compared the cognitive performance of individuals with disordered screen use to those without it.</p> <p>Our findings paint a concerning picture.</p> <h2>Differences in cognitive function</h2> <p>Across these rigorously peer-reviewed studies, individuals with disordered screen use consistently demonstrated significantly poorer cognitive performance compared to others.</p> <p>The most affected cognitive domain was attention, and specifically sustained attention, which is the ability to maintain focus on an unchanging stimulus for an extended period.</p> <p>The second-most notable difference was in their “executive functioning” – particularly in impulse control, which is the ability to control one’s automatic responses.</p> <p>Interestingly, the type of screen activity didn’t make a difference in the results. The trend also wasn’t confined to children, but was observed across all age groups.</p> <h2>Two ways to interpret the results</h2> <p>Why do people with disordered screen-related behaviours have poorer cognitive functioning?</p> <p>The first explanation is that disordered screen use actually leads to poorer cognitive function, including poorer attention skills (but we’ll need more experimental and longitudinal studies to establish causality).</p> <p>If this is the case, it may be the result of being constantly bombarded by algorithms and features designed to capture our attention. By diverting our focus outward, screen use may weaken one’s intrinsic ability to concentrate over time.</p> <p>Crucially, impaired attention also <a href="https://akjournals.com/view/journals/2006/10/1/article-p77.xml">makes it harder to disengage</a> from addictive behaviours, and would therefore make it harder to recognise when screen use has become a problem.</p> <p>The second explanation is that people who already have poorer cognitive functioning (such as less inhibitory control) are more likely to engage in disordered screen use.</p> <p>This could be a result of the plethora of addictive cues designed to keep us glued to our screens. Being bombarded by these could make it harder to <a href="https://akjournals.com/view/journals/2006/9/4/article-p990.xml">pull the brakes</a> on screen use.</p> <p>Although the literature doesn’t seem to favour this explanation – and does seem to suggest that cognitive functioning is impaired as a result of disordered screen use – it’s still a possibility we can’t rule out.</p> <p>Attention is the bedrock of everyday tasks. People with weakened attention may struggle to keep up in less stimulating environments, such as a static workplace or classroom. They may find themselves turning to a screen as a result.</p> <p>Similarly, people with less inhibitory control would also find it more challenging to moderate their screen use. This could be what drives them towards problematic screen-related behaviours in the first place.</p> <h2>Who should shoulder the responsibility?</h2> <p>Research indicates people with impaired cognitive functioning usually aren’t as well equipped to moderate their own screen time.</p> <p>Many users with disordered screen use are <a href="https://www.sciencedirect.com/science/article/pii/S0747563220302326?casa_token=BQv_N_MFffYAAAAA:AsGkAfdwXjCZHJB463G40Mx-ckS2Q1c8jSOn2SWR_9iW64eWaQsru1IJAZBDCgSPXwhZ3Qwl">young</a>, with mainly males engaging in internet gaming and mainly females engaging in social media use. Neurodiverse people are <a href="https://www.mdpi.com/1660-4601/19/9/5587">also at greater risk</a>.</p> <p>Tech companies are driven by the goal of <a href="https://www.theguardian.com/technology/2017/apr/18/netflix-competitor-sleep-uber-facebook">capturing our attention</a>. For instance, Netflix chief executive Reed Hastings acknowledged the company’s <a href="https://www.theguardian.com/technology/2017/apr/18/netflix-competitor-sleep-uber-facebook">most formidable competitor was sleep</a>.</p> <p>At the same time, researchers find themselves struggling to keep up with the pace of technological innovation. A potential path forward is to encourage open-access data policies from tech companies, so researchers can delve deeper into the study of screen use and its effect on individuals. <!-- Below is The Conversation's page counter tag.

Our obsession with taking photos is changing how we remember the past

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/giuliana-mazzoni-175429">Giuliana Mazzoni</a>, <a href="https://theconversation.com/institutions/university-of-hull-1191">University of Hull</a></em></p> <p>I recently visited the <a href="http://hermitage--www.hermitagemuseum.org/wps/portal/hermitage/?lng=sv">Hermitage</a> in St Petersburg, Russia – one of the best art museums in the world. I was expecting to serenely experience its masterpieces, but my view was blocked by a wall of smart phones taking pictures of the paintings. And where I could find a bit of empty space, there were people taking selfies to create lasting memories of their visit.</p> <p>For many people, taking hundreds, if not thousands, of pictures is now a crucial part of going on holiday – documenting every last detail and posting it on social media. But how does that affect our actual memories of the past – and how we view ourselves? As an expert on memory, I was curious.</p> <p>Unfortunately, psychological research on the topic is so far scant. But we do know a few things. We use smart phones and new technologies <a href="http://studie-life.de/en/life-reports/smart-payments;%20https://www.researchgate.net/profile/Tim_Fawns/publication/275331048_Blended_Memory_the_Changing_Balance_of_Technologically-mediated_Semantic_and_Episodic_Memory/links/56962c6d08ae820ff07594ee.pdf">as memory repositories</a>. This is nothing new – humans have always used external devices as an aid when acquiring knowledge and remembering.</p> <p>Writing certainly serves this function. Historical records are collective external memories. Testimonies of migrations, settlement or battles help entire nations trace a lineage, a past and an identity. In the life of an individual, written diaries serve a similar function.</p> <h2>Memory effects</h2> <p>Nowadays we tend to commit very little to memory – we entrust a huge amount to the cloud. Not only is it almost unheard of to recite poems, even the most personal events are generally recorded on our cellphones. Rather than remembering what we ate at someone’s wedding, we scroll back to look at all the images we took of the food.</p> <p>This has serious consequences. Taking photos of an event rather than being immersed in it has been shown to lead to <a href="https://theconversation.com/memory-loss-isnt-just-an-old-persons-problem-heres-how-young-people-can-stay-mentally-fit-102352">poorer recall of the actual event</a> – we get distracted in the process.</p> <p>Relying on photos to remember has a similar effect. Memory needs to be exercised on a regular basis in order to function well. There are many studies documenting the importance of memory retrieval practice – <a href="http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.738.2035&amp;rep=rep1&amp;type=pdf">for example in university students</a>. Memory is and will remain essential for learning. There is indeed some evidence showing that committing almost all knowledge and memories to the cloud <a href="https://www.journals.uchicago.edu/doi/10.1086/691462">might hinder the ability to remember</a>.</p> <p>However, there is a silver lining. Even if some studies claim that all this makes us more stupid, what happens is actually shifting skills from purely being able to remember to being able to manage the way we remember more efficiently. This is called metacognition, and it is an overarching skill that is also essential for students – for example when planning what and how to study. There is also substantial and reliable evidence that external memories, selfies included, <a href="https://www.ncbi.nlm.nih.gov/pubmed/23957379">can help</a> individuals with memory impairments.</p> <p>But while photos can in some instances help people to remember, the quality of the memories may be limited. We may remember what something looked like more clearly, but this could be at the expense of other types of information. One study showed that while photos could help people remember what they saw during some event, they <a href="https://journals.sagepub.com/doi/abs/10.1177/0956797617694868">reduced their memory of what was said</a>.</p> <h2>Identity distortions?</h2> <p>There are some rather profound risks when it comes to personal memory. Our identity is a product of our life experiences, which can be easily accessed through our memories of the past. So, does constant photographic documentation of life experiences alter how we see ourselves? There is no substantial empirical evidence on this yet, but I would speculate that it does.</p> <p>Too many images are likely to make us remember the past in a fixed way – blocking other memories. While it is <a href="https://theconversation.com/what-is-your-first-memory-and-did-it-ever-really-happen-95953">not uncommon for early childhood memories</a> to be based on photos rather than the actual events, these are not always true memories.</p> <p>Another issue is the fact that research has uncovered <a href="https://www.sciencedirect.com/science/article/pii/S0747563216302503;%20http://www.vulture.com/2014/01/history-of-the-selfie.html">a lack of spontaneity in selfies</a> and many other photos. They are planned, the poses are not natural and at times the image of the person is distorted. They also reflect a narcissistic tendency which shapes the face in unnatural mimics – artificial big smiles, sensual pouts, funny faces or offensive gestures.</p> <p>Importantly, selfies and many other photos are also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5318447/">public displays</a> of specific attitudes, intentions and stances. In other words, they do not really reflect who we are, they reflect what we want to show to others about ourselves at the moment. If we rely heavily on photos when remembering our past, we may create a distorted self identity based on the image we wanted to promote to others.</p> <p>That said, our natural memory isn’t actually perfectly accurate. Research shows that we often <a href="https://theconversation.com/the-real-you-is-a-myth-we-constantly-create-false-memories-to-achieve-the-identity-we-want-103253">create false memories about the past</a>. We do this in order to maintain the identity that we want to have over time – and avoid conflicting narratives about who we are. So if you have always been rather soft and kind – but through some significant life experience decide you are tough – you may dig up memories of being aggressive in the past or even completely make them up.</p> <p>Having multiple daily memory reports on the phone of how we were in the past might therefore render our memory less malleable and less adaptable to the changes brought about by life – making our identity more stable and fixed.</p> <p>But this can create problems if our present identity becomes different from our fixed, past one. That is an uncomfortable experience and exactly what the “normal” functioning of memory is aimed to avoid – it is malleable so that we can have a non-contradictory narrative about ourselves. We want to think of ourselves as having a certain unchanging “core”. If we feel unable to change how we see ourselves over time, this could seriously affect our sense of agency and mental health.</p> <p>So our obsession with taking photos may be causing both memory loss and uncomfortable identity discrepancies.</p> <p>It is interesting to think about how technology changes the way we behave and function. As long as we are aware of the risks, we can probably mitigate harmful effects. The possibility that actually sends shivers to my spine is that we lose all those precious pictures because of some widespread malfunctioning of our smart phones.</p> <p>So the next time you’re at a museum, do take a moment to look up and experience it all. Just in case those photos go missing.<!-- Below is The Conversation's page counter tag.

Compulsory voting in Australia is 100 years old. We should celebrate how special it makes our democracy

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/paul-strangio-1232">Paul Strangio</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p>For nearly 200 years, the notion of American political exceptionalism has had currency in the United States: it is an idea rooted in the nation’s status as the first modern republic. As we watch from afar, disturbed yet mesmerised by the latest chapter of violent political division in America, the country seems less a paragon than a symbol of democratic pathology.</p> <p>America’s certainty in its political uniqueness is symptomatic of a brash national chauvinism. By way of contrast, Australia is prone, if anything, to undue bashfulness about its democratic credentials. How else can we explain that this month marks the centenary of the most extraordinary feature of the country’s democratic architecture, and yet the anniversary is slipping by with neither comment nor reflection. I refer to compulsory voting, which was legislated in the federal parliament in July 1924.</p> <p>Compulsory voting is not unique to Australia. Calculating how many countries abide by the practice is notoriously difficult, since in around half the nations where compulsory voting exists in name it is not enforced. Most estimates, however, put the figure in the vicinity of 20 to 30.</p> <p>If not unique, Australia’s experience of compulsory voting is highly distinctive for a number of reasons.</p> <p>First, its emergence in the early 20th century was consistent with the nation’s larger tradition of innovation and experimentation when it came to electoral institutions and practices. This record is typically traced back to the pioneering in the 1850s of the secret ballot (sometimes called the “Australian ballot”) in a number of the Australian colonies and the embrace of other advanced democratic measures in the second half of the 19th century.</p> <p>These included manhood suffrage, payment of MPs and the extension of the franchise to women, beginning in South Australia in 1894. The innovations continued in the 20th century with such things as preferential voting and non-partisan bureaucratic electoral administration.</p> <p>Second, Australia is alone in embracing compulsory voting among the Anglophone democracies to which it typically compares itself. The electoral systems of Britain, Canada, New Zealand and the United States are all based on voluntary voting.</p> <p>Third, unlike many other compulsory voting countries, Australia does not pay lip service to its operation. Electoral authorities enforce compulsory voting, albeit leniently. It has been strongly upheld by the courts and is backed by a regime of sanctions for non-compliance.</p> <p>Fourth, compulsory voting has been consistently and unambiguously successful in achieving high voter turnout. Though there has been a slight downward trend in turnout at the past five national elections (it hit a low of 90.5% in 2022), it has not fallen below 90% since the adoption of compulsory voting a century ago.</p> <p>This is around 30% higher than the recent average turnout in countries with voluntary voting. It is also well above the recent average in countries with compulsory voting systems.</p> <p>Fifth, the public has strongly and consistently backed the practice. Evidence from more than half a century of opinion polls and election study surveys shows support hovering around the 70% mark.</p> <h2>An impregnable practice</h2> <p>Perhaps the most singular aspect of the nation’s experience of compulsory voting, however, is how seemingly impregnable is the practice if measured by its durability, the dearth of controversy over it, the consistency of its enforcement by authorities and the way citizens have dutifully complied with and supported it. Together these things make Australia an exemplar of compulsory voting internationally.</p> <p>This is not to say compulsory voting has been a sacred cow in Australia. In the final decades of the 20th century and first decade of this century, there was a concerted push to end the practice emanating principally from within the Liberal Party.</p> <p>The torchbearer of the agitation for voluntary voting was the avowed libertarian South Australian senator, Nick Minchin. <a href="https://classic.austlii.edu.au/au/journals/SGSocUphAUCon/2003/11.html">For Minchin</a>, compulsory voting was anathema:</p> <blockquote> <p>[…] in relation to the most important single manifestation of democratic will, the act of voting, I profoundly detest Australia’s denial of individual choice. It seems to me that an essential part of a liberal democracy should be the citizen’s legal right to decide whether or not to vote. The denial of that right is an affront to democracy.</p> </blockquote> <p>Minchin had a number of like-minded supporters of voluntary voting in the Liberal Party. Among them, importantly, was John Howard, whose prime ministership coincided with the mobilisation to abolish compulsory voting.</p> <p>Howard had been on record as an opponent of the practice since his entry to the federal parliament in 1974. The Liberal Party campaign against compulsory voting manifested in, among other things:</p> <ul> <li>the party’s federal council resolving in favour of voluntary voting</li> <li>shadow cabinet endorsing a recommendation for a change of policy to voluntary voting being placed before the joint Liberal-National party parliamentary room</li> <li>the introduction in the South Australian parliament of two bills to repeal compulsory voting by successive Liberal state governments</li> <li>Coalition members of the Joint Standing Committee on Electoral Matters repeatedly recommending the abolition of the practice.</li> </ul> <p>In the end, these agitations achieved nought. The most fundamental reason was that the opponents of compulsory voting failed to generate community resentment towards the system. Howard, while restating his preference for voluntary voting, admitted as much in 2005 when shutting down debate on the issue in his government:</p> <blockquote> <p>As I move around the country, I don’t get people stopping me in the street and saying, “You’ve got to get rid of compulsory voting.”</p> </blockquote> <p>Indeed, election survey data suggests the Liberal campaign coincided with a firming of public support for compulsory voting. In the two decades since, opposition has been dormant. For the foreseeable future, Australia’s compulsory voting regime is secure.</p> <h2>An Australian democratic exceptionalism?</h2> <p>As noted above, compulsory voting has kept voter turnout at elections above 90% for the past century. Kindred democracies marvel at, and envy, this level of participation. It affords legitimacy to election outcomes in this country. Significantly, it also produces a socially even turnout.</p> <p>Compare this to the situation in this month’s United Kingdom election. Turnout <a href="https://www.theguardian.com/politics/article/2024/jul/12/lowest-turnout-in-uk-general-election-since-universal-suffrage-report-shows">is estimated</a> to have slumped to a record low 52%. There was a clear pattern of the “haves” exercising much greater say at the ballot box than the “have nots”. Those who stayed away from the polls were predominantly less well-off, non-homeowners, the young, the lower-educated and of minority ethnic background.</p> <p>Australia cannot be complacent in this regard. Low and declining turnout in remote electorates with high Indigenous populations is the most worrying chink in the performance of compulsory voting. In 2022, turnout in the Northern Territory seat of Lingiari fell to 66.8%. Even so, the practice largely succeeds in achieving inclusive voter participation across the country.</p> <p>Crucially, compulsory voting is also recognised as one reason the political centre holds better in Australia than in many comparable nations. It exercises a moderating influence because it ensures it is not only impassioned partisans at either end of the political spectrum who participate in elections. This in turn means they are not the chief focus of governments and political parties.</p> <p>Under a compulsory voting system, middle-of-the-road citizens and their concerns and sensibilities count. This inhibits the trend towards polarisation and grievance politics evident in other parts of the globe. It helps explain why Australia has been less receptive to the aggressive conservative populism that has taken root in the United States and Europe.</p> <p>Compulsory voting also goes hand in hand with other institutional bulwarks of the nation’s democracy. While there is plenty of evidence in Australia of increasing disaffection with politics, one thing that helps bolster faith in the democratic system is the politically independent national electoral authority, the Australian Electoral Commission.</p> <p>The AEC’s trusted impartial administration of the electoral system lends integrity to the democratic process. So do the many procedures it manages to facilitate voting. To name a few: Saturday election days, assistance for the ill, aged and those from non-English-speaking backgrounds, mobile polling stations, postal, absentee and early voting, and active and regular updating of registration.</p> <p>Indeed, Australia has been described as “the most voter-friendly country in the world”. Compulsory voting encourages this accessibility: if citizens are obliged to vote, then it becomes incumbent to smooth the path to them participating. The ease of voting in Australia contrasts with what goes on elsewhere, for example, the rampant state-based voter-suppression practices in the United States.</p> <p>Dare we suggest, then, that compulsory voting is a mainstay of an Australian democratic exceptionalism? That we little note, let alone extol, the practice is perhaps not only a product of an inherent national modesty but because it is second nature after 100 years. Habituated to being compelled to participate in elections, we are inured to its specialness.</p> <p>Let’s hope this casual familiarity does not induce apathy rather than vigilance when next the system is challenged.<!-- Below is The Conversation's page counter tag.

It can also trigger feelings of <a href="https://psycnet.apa.org/doiLanding?doi=10.1037%2Femo0000817">loneliness or meaninglessness</a>.</p> <p>We can use nostalgia to <a href="https://psycnet.apa.org/doiLanding?doi=10.1037%2Fa0025167">turn around a negative mood</a> or enhance our sense of <a href="https://psycnet.apa.org/doiLanding?doi=10.1037%2Femo0000817">self, meaning and positivity</a>.</p> <p>Research suggests nostalgia alters activity in the <a href="https://academic.oup.com/scan/article/17/12/1131/6585517">brain regions associated with reward processing</a> – the same areas involved when we seek and receive things we like. This could explain the <a href="https://www.sciencedirect.com/science/article/abs/pii/S2352250X22002445?via%3Dihub">positive feelings</a> it can bring.</p> <p>Nostalgia can also increase feelings of loneliness and sadness, particularly if the memories highlight dissatisfaction, grieving, loss, or wistful feelings for the past. This is likely due to activation of <a href="https://www.sciencedirect.com/science/article/pii/S2352250X22002445?casa_token=V31ORDWcsx4AAAAA:Vef9hiwUz9506f5PYGsXH-JxCcnsptQnVPNaAGares2xTU5JbKSHakwGpLxSRO2dNckrdFGubA">brain areas</a> such as the amygdala, responsible for processing emotions and the prefrontal cortex that helps us integrate feelings and memories and regulate emotion.</p> <h2>How to get back there</h2> <p>There are several ways we can <a href="https://psycnet.apa.org/fulltext/2006-20034-013.html">trigger</a> or tap into nostalgia.</p> <p>Conversations with family and friends who have shared experiences, unique objects like photos, and smells can <a href="https://www.sciencedirect.com/science/article/abs/pii/S2352250X23000076">transport us back</a> to old times or places. So can a favourite song or old TV show, reunions with former classmates, even social media <a href="https://www.theverge.com/2015/3/24/8284703/facebook-on-this-day-nostalgia-recap">posts and anniversaries</a>.</p> <p>What we eat and drink can trigger <a href="https://www.emerald.com/insight/content/doi/10.1108/QMR-06-2012-0027/full/html">food-evoked nostalgia</a>. For instance, when we think of something as “<a href="https://theconversation.com/health-check-why-do-we-crave-comfort-food-in-winter-118776">comfort food</a>”, there are likely elements of nostalgia at play.</p> <p>Foods you found comforting as a child can evoke memories of being cared for and nurtured by loved ones. The form of these foods and the stories we tell about them may have been handed down through generations.</p> <p>Food-evoked nostalgia can be very powerful because it engages multiple senses: taste, smell, texture, sight and sound. The sense of <a href="https://www.tandfonline.com/doi/full/10.1080/09658211.2013.876048?casa_token=wqShWbRXJaYAAAAA%3AqJabgHtEbPtEQp7qHnl7wOb527bpGxzIJ_JwQX8eAyq1IrM_HQFIng8ELAMyuoFoeZyiX1zeJTPf">smell</a> is closely linked to the limbic system in the brain responsible for emotion and memory making food-related memories particularly vivid and emotionally charged.</p> <p>But, food-evoked nostalgia can also give rise to <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/hpja.873">negative memories</a>, such as of being forced to eat a certain vegetable you disliked as a child, or a food eaten during a sad moment like a loved ones funeral. Understanding why these foods <a href="https://www.tandfonline.com/doi/full/10.1080/02699931.2022.2142525?casa_token=16kAPHUQTukAAAAA%3A9IDvre8yUT8UsuiR_ltsG-3qgE2sdkIFgcrdH3T5EYbVEP9JZwPcsbmsPLT6Kch5EFFs9RPsMTNn">evoke negative memories</a> could help us process and overcome some of our adult food aversions. Encountering these foods in a positive light may help us reframe the memory associated with them.</p> <h2>What people told us about food and nostalgia</h2> <p>Recently <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/hpja.873">we interviewed eight Australians</a> and asked them about their experiences with food-evoked nostalgia and the influence on their mood. We wanted to find out whether they experienced food-evoked nostalgia and if so, what foods triggered pleasant and unpleasant memories and feelings for them.</p> <p>They reported they could use foods that were linked to times in their past to manipulate and influence their mood. Common foods they described as particularly nostalgia triggering were homemade meals, foods from school camp, cultural and ethnic foods, childhood favourites, comfort foods, special treats and snacks they were allowed as children, and holiday or celebration foods. One participant commented:</p> <blockquote> <p>I guess part of this nostalgia is maybe […] The healing qualities that food has in mental wellbeing. I think food heals for us.</p> </blockquote> <p>Another explained</p> <blockquote> <p>I feel really happy, and I guess fortunate to have these kinds of foods that I can turn to, and they have these memories, and I love the feeling of nostalgia and reminiscing and things that remind me of good times.</p> </blockquote> <p>Understanding food-evoked nostalgia is valuable because it provides us with an insight into how our sensory experiences and emotions intertwine with our memories and identity. While we know a lot about how food triggers nostalgic memories, there is still much to learn about the specific brain areas involved and the differences in food-evoked nostalgia in different cultures.</p> <p>In the future we may be able to use the science behind food-evoked nostalgia to help people experiencing dementia to tap into lost memories or in psychological therapy to help people reframe negative experiences.</p> <p>So, if you are ever feeling a little down and want to improve your mood, consider turning to one of your favourite comfort foods that remind you of home, your loved ones or a holiday long ago. Transporting yourself back to those times could help turn things around.<!-- Below is The Conversation's page counter tag.

"Blew our marriage to smithereens”: Keith Urban's emotional admission

<p>Keith Urban has opened up about the rocky start to his marriage with Nicole Kidman in an emotional speech in front of the Hollywood elite. </p> <p>During his speech at the 49th AFI Life Achievement Award: A Tribute to Nicole Kidman, which was filmed in April but aired over the weekend, Urban spoke candidly about their relationship and the early days of their marriage, when Urban spent time in rehab. </p> <p>Taking to the stage, he said, “We got married in June 2006, and barely four months into our marriage, the addictions that I had done really nothing about blew our marriage to smithereens.”</p> <p>“I went into the Betty Ford Center for three months,” Urban continued.</p> <p>“Four months into a marriage, and I’m in rehab for three months with no idea what was going to happen to us.”</p> <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-permalink="https://www.instagram.com/reel/C8dWHBDIC7c/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/reel/C8dWHBDIC7c/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by American Film Institute (@americanfilminstitute)</a></p> </div> </blockquote> <p>“If you want to see what love in action really looks like, give that a whirl,” he said. </p> <p>“Nic pushed through every negative voice — I’m sure even some of her own — and she chose love.

She knows the importance of expressing feelings as well. I wasn’t raised like this at all so our girls are very lucky to be learning from you, baby. I’m learning too.”</p> <p><em>Image credits: Xavier Collin/Image Press Agency/Shutterstock Editorial </em></p>

In Australia, it’s now only used for 16% of in-person transactions, down from <a href="https://www.rba.gov.au/publications/bulletin/2023/jun/cash-use-and-attitudes-in-australia.html">about 70%</a> in 2007.</p> <p>The situation is so dire that on Monday, independent federal MP Andrew Gee introduced a <a href="https://www.smh.com.au/politics/federal/saving-the-lobster-prawn-and-pineapple-mps-fight-to-force-shops-to-take-cash-20240603-p5jit4.html">private member’s bill</a> that would force businesses to accept cash or else face big fines.</p> <p>The reality is that over the past decade, technological advancements have utterly transformed the way we pay for goods and services.</p> <p>Phones and smartwatches can now easily be used to pay by card, and buy-now-pay-later schemes and cryptocurrency payments offer further alternatives.</p> <p>The shift away from cash only <a href="https://www.worldbank.org/en/news/press-release/2022/06/29/covid-19-drives-global-surge-in-use-of-digital-payments">accelerated</a> throughout the COVID pandemic, as health experts recommended avoiding using it for hygiene reasons.</p> <p>Despite these big changes in <em>how</em> we spend money, Australians have perhaps been more focused on <em>how much</em> amid a stubborn cost-of-living crisis.</p> <p>In light of this, our research team wanted to investigate how our choice of payment method can interact with our actual spending habits.</p> <p>Our <a href="https://www.sciencedirect.com/science/article/pii/S0022435924000216#bib0104">latest research</a> offers a simple solution for anyone looking to save money — carry more cash!</p> <h2>We pay less when we pay cash</h2> <p>Drawing on both academic and industry sources, our research team combined the results from more than four decades of prior research on spending behaviour and payment methods into a large dataset.</p> <p>This data spanned 71 research papers, 17 countries, and more than 11,000 participants. State-of-the-art meta-analysis techniques then allowed us to collectively analyse the results from all these prior studies, and re-examine their insights.</p> <p>We found that cashless payments were indeed associated with higher levels of consumer spending compared to cash transactions, something that is referred to in the literature as the “cashless effect”.</p> <p>This cashless effect was consistent across all other payment methods in the data set.</p> <p>Put simply, it doesn’t matter whether you use a credit card, debit card or a buy-now-pay-later service – you are likely to spend more money using cashless methods than when you pay with cash.</p> <h2>The pain of paying</h2> <p>Under the traditional economic view that consumers behave rationally, there should be no differences in spending behaviour between different payment methods – money is money after all.</p> <p>But the existence of the cashless effect shows that the payment methods we use do indeed influence our spending behaviour.</p> <p>The leading theory to explain this effect attributes it to differences in the “pain of paying”, a concept <a href="https://www.researchgate.net/publication/280711796_The_Pain_of_Paying">first coined in 1996</a> that describes the emotions we feel when spending money.</p> <p>Importantly, our choice of payment method can influence the level of pain felt.</p> <p>When paying with cash, we have to physically count out notes and coins and hand them over. Humans seek to avoid losses, and paying by cash sees us physically lose a tangible object.</p> <p>Conversely, nothing has to be handed over to pay cashlessly. We don’t lose anything tangible with a swipe or a tap, so it feels less painful.</p> <p>Preliminary neurological evidence suggests that the “pain of paying” isn’t just an abstract metaphor, and we may feel actual psychological pain with each transaction we make.</p> <p><a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2901808">Research</a> employing functional magnetic resonance imaging (fMRI) scans to observe brain activity in consumers has shown that paying activates brain regions related to experiencing psychological discomfort.</p> <p>Picture this: You’re at a theme park, excited for a fun day. You use your smartwatch to pay for snacks, souvenirs and rides. It’s all so convenient that you don’t realise how much you’re spending until you check your account later and see that you have completely blown your budget!</p> <p>This is the cashless effect in action − if nothing is physically handed over, it’s easy to lose track of how much is spent.</p> <h2>A great tool for budgeting – while it lasts</h2> <p>The cost of living crisis has made spending control front-of-mind for many people. Our meta-analysis suggests that returning to “cold hard cash” whenever possible could be one valuable tool to help.</p> <p>The increased friction felt when using cash could help people better control their money, even just by providing a moment to pause and consider whether a transaction is necessary.</p> <p>This could help individuals make more mindful decisions, saving money while they can in an increasingly cashless world.<!-- Below is The Conversation's page counter tag.

"Ruined our trip": Mum shell-shocked by $130k fine

<p>A mother has been slapped with a hefty fine after her children were caught in a seemingly innocent act while on a beach holiday. </p> <p>Charlotte Russ took her five kids on a trip to Pismo Beach in California, where her children started enthusiastically collecting what they thought were ordinary seashells. </p> <p>"My kids they thought they were collecting seashells, but they were actually collecting clams, 72 to be exact,"  Russ told local news outlet <em><a href="https://abc7.com/post/fresno-woman-fined-88k-after-kids-collect-clams/14859295/" target="_blank" rel="nofollow noreferrer noopener">ABC 7</a></em>.</p> <p>Clamming is highly regulated in California, meaning if you don't have a fishing license, you cannot catch the small sea creatures. </p> <p>She received a citation right there on the beach and was later notified she has to pay close to $89,000, or $133,000 AUD, for her kids' seemingly innocent treasure hunt. </p> <p>"It made me really sad and depressed, and it kind of ruined our trip," said Russ.</p> <p>Department of Fish and Wildlife's Lieutenant Matthew Gil defended the fine, saying there are rules in place for a reason. </p> <p>"The reason we got it we have these regulations is because we have to let them get to 4 and a half inches so they can spawn so they can have they can have offspring every year, and they have juvenile clams," said Lt. Gil.</p> <p>Russ said her kids have learned their lesson, saying, "They know now at the beach don't touch anything, but they know now what a clam is, compared to what a seashell is now, I've had to explain that to them."</p> <p>The mother was able to plead her case with a San Luis Obispo County Judge, who reduced her fine to $500 dollars, and after she "won" her case, Russ got a shellfish tattoo to commemorate the incident.</p> <p>"It was definitely one expensive trip to Pismo, unforgettable," said Russ.</p> <p><em>Image credits: ABC 7</em></p>
