Stamp duty is holding us back from moving homes – we’ve worked out how much

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/nick-garvin-1453835">Nick Garvin</a>, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a></em></p> <p>If just one state of Australia, New South Wales, scrapped its stamp duty on real-estate transactions, about 100,000 more Australians would move homes each year, according to our <a href="https://e61.in/wp-content/uploads/2024/02/Stamp-duty-effects-on-purchases-and-moves.pdf">best estimates</a>.</p> <p>Stamp duty is an unquestioned part of buying a home in Australia – you put your details in an online mortgage calculator, and stamp duty is automatically deducted from the amount you have to contribute.</p> <p>It’s easy to overlook how much more affordable a home would be without it.</p> <p>That means it’s also easy to overlook how much more Australians would buy and move if stamp duty wasn’t there.</p> <p>The 2010 Henry Tax Review found stamp duty was <a href="https://treasury.gov.au/sites/default/files/2019-10/afts_final_report_part_2_vol_1_consolidated.pdf">inequitable</a>. It taxes most the people who most need to or want to move.</p> <p>The review reported: "Ideally, there would be no role for any stamp duties, including conveyancing stamp duties, in a modern Australian tax system. Recognising the revenue needs of the States, the removal of stamp duty should be achieved through a switch to more efficient taxes, such as those levied on broad consumption or land bases."</p> <p>But does stamp duty actually stop anyone moving? It’s a claim more often made than assessed, which is what our team at the <a href="https://e61.in/wp-content/uploads/2024/02/Stamp-duty-effects-on-purchases-and-moves.pdf">e61 Institute</a> set out to do.</p> <p>We used real-estate transaction data and a natural experiment.</p> <h2>What happened when Queensland hiked stamp duty</h2> <p>In 2011, Queensland hiked stamp duty for most buyers by removing some concessions for owner-occupiers at short notice.</p> <p>For owner-occupiers it increased stamp duty by about one percentage point, lifting the average rate from 1.26% of the purchase price to 2.27%.</p> <p>What we found gives us the best estimate to date of what stamp duty does to home purchases.</p> <p>A one percentage point increase in stamp duty causes the number of home purchases to decline by 7.2%.</p> <p>The number of moves (changes of address) falls by about as much.</p> <p>The effect appears to be indiscriminate. Purchases of houses fell about as much as purchases of apartments, and purchases in cities fell about as much as purchases in regions.</p> <p>Moves between suburbs and moves interstate dropped by similar rates.</p> <p>With NSW stamp duty currently averaging about <a href="https://conveyancing.com.au/need-to-know/stamp-duty-nsw">3.5%</a> of the purchase price, our estimates suggest there would be about 25% more purchases and moves by home owners if it were scrapped completely. That’s 100,000 moves.</p> <p>Victoria’s higher rate of stamp duty, about <a href="https://www.sro.vic.gov.au/rates-taxes-duties-and-levies/general-land-transfer-duty-property-current-rates">4.2%</a>, means if it was scrapped there would be about 30% more purchases. That’s another 90,000 moves.</p> <h2>Even low headline rates have big effects</h2> <p>The big effect from small-looking headline rates ought not to be surprising.</p> <p>When someone buys a home, they typically front up much less cash than the purchase price. While stamp duty seems low as a percentage of the purchase price, it is high as a percentage of the cash the buyer needs to find.</p> <p>Here’s an example. If stamp duty is 4% of the purchase price, and a purchaser pays $800,000 for a property with a mortgage deposit of $160,000, the $32,000 stamp duty adds 20%, not 4%, to what’s needed.</p> <p>If the deposit takes five years to save, stamp duty makes it six.</p> <p>A similar thing happens when an owner-occupier changes address. If the buyer sells a fully owned home for $700,000 and buys a new home for $800,000, the upgrade ought to cost them $100,000. A 4% stamp duty lifts that to $132,000.</p> <p>Averaged across all Australian cities, stamp duty costs about <a href="https://e61.in/wp-content/uploads/2024/02/Stepped-on-by-Stamp-Duty.pdf">five months</a> of after-tax earnings. In Sydney and Melbourne, it’s six.</p> <h2>Stamp duty has bracket creep</h2> <p>This cost has steadily climbed from around <a href="https://e61.in/wp-content/uploads/2024/02/Stepped-on-by-Stamp-Duty.pdf">six weeks</a> of total earnings in the 1990s. It has happened because home prices have climbed faster than incomes and because stamp duty has brackets, meaning more buyers have been pushed into higher ones.</p> <p>Replacing the stamp duty revenue that states have come to rely on would not be easy, but a switch would almost certainly help the economy function better.</p> <p>The more that people are able to move, the more they will move to jobs to which they are better suited, boosting productivity.</p> <p>The more that people downsize when they want to, the more housing will be made available for others.</p> <p>Our findings suggest the costs are far from trivial, making a switch away from stamp duty worthwhile, even if it is disruptive and takes time.<!-- Below is The Conversation's page counter tag.

Tennis star "heartbroken" as injury puts life on hold

<p>Aussie tennis star Storm Hunter has suffered a devastating injury just one day before the nation's qualifying tie against Mexico. </p> <p>The 29-year-old has had to put her Olympic dream and plans to crack the world’s top 100 on hold, after she fell and ruptured her right Achilles tendon. </p> <p>The incident occurred on Thursday’s final practice session for Australia’s Billie Jean King Cup qualification tie against Mexico on Friday. </p> <p>Hunter took to Instagram to announce the bad news, with a picture of herself during one of the games.</p> <p>“I am devastated and heartbroken but incredibly grateful to be around the team and I know I have a great group of people around me that will help me get back on court as soon as possible,” she wrote. </p> <p>“Thank you so much everyone for the messages of support and love, I’m excited to stay for the tie and support our Aussie girls.”</p> <blockquote class="instagram-media" style="background: #FFF;

People in the world’s ‘blue zones’ live longer – their diet could hold the key to why

<p><em><a href="https://theconversation.com/profiles/justin-roberts-1176632">Justin Roberts</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>; <a href="https://theconversation.com/profiles/joseph-lillis-1505087">Joseph Lillis</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>, and <a href="https://theconversation.com/profiles/mark-cortnage-438941">Mark Cortnage</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a></em></p> <p>Ageing is an inevitable part of life, which may explain our <a href="https://time.com/4672969/why-do-people-want-to-live-so-long/">strong fascination</a> with the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2726954">quest for longevity</a>. The allure of <a href="https://pubmed.ncbi.nlm.nih.gov/26566891/">eternal youth</a> drives a <a href="https://www.alliedmarketresearch.com/longevity-and-anti-senescence-therapy-market-A14010">multi-billion pound industry</a> ranging from anti-ageing products, supplements and <a href="https://www.everydayhealth.com/diet-nutrition/longevity-diet">diets</a> for those hoping to extend their lifespan.</p> <p>f you look back to the turn of the 20th century, average life expectancy in the UK was around 46 years. Today, it’s closer to <a href="https://population.un.org/wpp/">82 years</a>. We are in fact <a href="https://pubmed.ncbi.nlm.nih.gov/27706136/">living longer than ever before</a>, possibly due to medical advancements and improved <a href="https://www.health.org.uk/publications/reports/mortality-and-life-expectancy-trends-in-the-uk">living and working conditions</a>.</p> <p>But living longer has also come at a price. We’re now seeing higher rates of <a href="https://www.who.int/data/gho/data/themes/mortality-and-global-health-estimates/ghe-leading-causes-of-death">chronic and degenerative diseases</a> – with heart disease consistently topping the list. So while we’re fascinated by what may help us live longer, maybe we should be more interested in being healthier for longer. Improving our “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4632858/">healthy life expectancy</a>” remains a global challenge.</p> <p>Interestingly, certain locations around the world have been discovered where there are a high proportion of centenarians who display remarkable physical and mental health. The <a href="https://pubmed.ncbi.nlm.nih.gov/15489066/">AKEA study of Sardinia, Italy</a>, as example, identified a “blue zone” (named because it was marked with blue pen), where there was a higher number of locals living in the central-eastern mountainous areas who had reached their 100th birthday compared with the wider Sardinian community.</p> <p>This longevity hotspot has since been expanded, and now includes several other areas around the world which also have greater numbers of longer-living, healthy people. Alongside Sardinia, these blue zones are now <a href="https://www.netflix.com/gb/title/81214929">popularly recognised</a> as: Ikaria, Greece; Okinawa, Japan; Nicoya, Costa Rica; and Loma Linda, California.</p> <p>Other than their long lifespans, people living in these zones also appear to share certain other commonalities, which centre around being <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3874460">part of a community</a>, having a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4224996/">life purpose</a>, eating <a href="https://pubmed.ncbi.nlm.nih.gov/33514872/">nutritious, healthy foods</a>, keeping <a href="https://www.nature.com/articles/s41398-021-01735-7">stress levels</a> low and undertaking purposeful daily <a href="https://pubmed.ncbi.nlm.nih.gov/30202288/">exercise or physical tasks</a>.</p> <p>Their longevity could also relate to their <a href="https://pubmed.ncbi.nlm.nih.gov/9010380/">environment</a>, being mostly rural (or less polluted), or because of <a href="https://pubmed.ncbi.nlm.nih.gov/22253498/">specific longevity genes</a>.</p> <p>However, studies indicate genetics may only account for <a href="https://pubmed.ncbi.nlm.nih.gov/8786073">around 20-25% of longevity</a> – meaning a person’s lifespan is a complex interaction between lifestyle and genetic factors, which contribute to a long and healthy life.</p> <h2>Is the secret in our diet?</h2> <p>When it comes to diet, each blue zone has its own approach – so one specific food or nutrient does not explain the remarkable longevity observed. But interestingly, a diet rich in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3662288">plant foods</a> (such as locally-grown vegetables, fruits and legumes) does appear to be reasonably consistent across these zones.</p> <p>For instance, the Seventh-day Adventists of Loma Linda are <a href="https://pubmed.ncbi.nlm.nih.gov/10641813/">predominately vegetarian</a>. For centenarians in Okinawa, <a href="https://pubmed.ncbi.nlm.nih.gov/20234038/">high intakes of flavonoids</a> (a chemical compound typically found in plants) from purple sweet potatoes, soy and vegetables, have been linked with <a href="https://pubmed.ncbi.nlm.nih.gov/11710359/">better cardiovascular health</a> – including lower cholesterol levels and lower incidences of stroke and heart disease.</p> <p>In Nicoya, consumption of locally produced rice and beans has been associated with <a href="https://pubmed.ncbi.nlm.nih.gov/34444746/">longer telomere length</a>. Telomeres are the structural part at the end of our chromosomes which protect our genetic material. Our telomeres get shorter each time a cell divides – so get progressively shorter as we age.</p> <p>Certain <a href="https://pubmed.ncbi.nlm.nih.gov/21102320/">lifestyle factors</a> (such as smoking and poor diet) can also shorten telomere length. It’s thought that telomere length acts as a <a href="https://pubmed.ncbi.nlm.nih.gov/31728493/">biomarker of ageing</a> – so having longer telomeres could, in part, be linked with longevity.</p> <p>But a plant-based diet isn’t the only secret. In Sardinia, for example, meat and fish is consumed in moderation in addition to locally grown vegetables and <a href="https://journalofethnicfoods.biomedcentral.com/articles/10.1186/s42779-022-00152-5">traditional foods</a> such as acorn breads, pane carasau (a sourdough flatbread), honey and soft cheeses.</p> <p>Also observed in several blue zone areas is the inclusion of <a href="https://www.jacc.org/doi/10.1016/j.jacc.2021.10.041">olive oil</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/33669360/">wine</a> (in moderation – around 1-2 glasses a day), as well as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3830687/">tea</a>. All of these contain powerful antioxidants which may help <a href="https://ncbi.nlm.nih.gov/pmc/articles/PMC10049696/">protect our cells</a> from damage <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6273542/">as we age</a>.</p> <p>Perhaps then, it’s a combination of the protective effects of various nutrients in the diets of these centenarians, which explains their exceptional longevity.</p> <p>Another striking observation from these longevity hot spots is that meals are typically <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7232892">freshly prepared at home</a>. Traditional blue zone diets also don’t appear to contain <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6538973/">ultra-processed foods</a>, fast foods or sugary drinks which may <a href="https://pubmed.ncbi.nlm.nih.gov/32330232/">accelerate ageing</a>. So maybe it’s just as important to consider what these longer-living populations are not doing, as much as what they are doing.</p> <p>There also appears to be a pattern of eating until 80% full (in other words partial <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9036399/">caloric reduction</a>. This could be important in also supporting how our cells deal with damage as we age, which could mean a longer life.</p> <p>Many of the factors making up these blue zone diets – primarily plant-based and natural whole foods – are associated with <a href="https://pubmed.ncbi.nlm.nih.gov/35706591/">lower risk of chronic diseases</a> such as <a href="https://pubmed.ncbi.nlm.nih.gov/28728684/">heart disease</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/37589638/">cancer</a>. Not only could such diets contribute to a <a href="https://pubmed.ncbi.nlm.nih.gov/37836577/">longer, healthier life</a>, but could support a more <a href="https://pubmed.ncbi.nlm.nih.gov/33397404/">diverse gut microbiome</a>, which is also associated with healthy ageing.</p> <p>Perhaps then we can learn something from these remarkable centenarians. While diet is only one part of the bigger picture when it comes to longevity, it’s an area we can do something about. In fact, it might just be at the heart of improving not only the quality of our health, but the quality of how we age.<!-- Below is The Conversation's page counter tag.

But as experts in <a href="https://www.cambridge.org/core/books/reluctant-reception/558E2A93FF99B8F295347A8FA2053698">migration</a> <a href="https://www.routledge.com/UN-Global-Compacts-Governing-Migrants-and-Refugees/Micinski/p/book/9780367218836">and</a> <a href="https://press.umich.edu/Books/D/Delegating-Responsibility">international relations</a>, we know funding is often used as a foreign policy tool, whereby allies are rewarded and enemies punished. In this context, we believe the cuts in funding for the UNRWA fit a wider pattern of the politicization of aid to refugees, particularly Palestinian refugees.</p> <h2>What is the UNRWA?</h2> <p>The UNRWA, short for the U.N. Relief and Works Agency for Palestine Refugees in the Near East, was established two years after about <a href="https://theconversation.com/the-nakba-at-75-palestinians-struggle-to-get-recognition-for-their-catastrophe-204782">750,000 Palestinians were expelled or fled from their homes</a> during the months leading up to the creation of the state of Israel in 1948 and the subsequent Arab-Israeli war.</p> <p>Prior to the UNRWA’s creation, international and local organizations, many of them religious, provided services to displaced Palestinians. But after <a href="https://cup.columbia.edu/book/refuge-and-resistance/9780231202855">surveying the extreme poverty</a> and dire situation pervasive across refugee camps, the U.N. General Assembly, including all Arab states and Israel, voted to create the UNRWA in 1949.</p> <p>Since that time, <a href="https://www.unrwa.org/what-we-do">the UNRWA has been the primary aid organization</a> providing food, medical care, schooling and, in some cases, housing for the 6 million Palestinians living across its five fields: Jordan, Lebanon, Syria, as well as the areas that make up the occupied Palestinian territories: the West Bank and Gaza Strip.</p> <p>The mass displacement of Palestinians – known as the <a href="https://theconversation.com/the-nakba-at-75-palestinians-struggle-to-get-recognition-for-their-catastrophe-204782">Nakba, or “catastrophe</a>” – occurred prior to the <a href="https://www.unhcr.org/about-unhcr/who-we-are/1951-refugee-convention">1951 Refugee Convention</a>, which defined refugees as anyone with a well-founded fear of persecution owing to “events occurring in Europe before 1 January 1951.” Despite a <a href="https://www.unhcr.org/sites/default/files/legacy-pdf/4ec262df9.pdf">1967 protocol extending the definition</a> worldwide, Palestinians are still excluded from the primary international system protecting refugees.</p> <p>While the UNRWA is responsible for providing services to Palestinian refugees, the United Nations also created the U.N. Conciliation Commission for Palestine in 1948 to seek a <a href="https://www.refworld.org/docid/4fe2e5672.html">long-term political solution</a> and “to facilitate the repatriation, resettlement and economic and social rehabilitation of the refugees and the payment of compensation.”</p> <p>As a result, the UNRWA does not have a mandate to push for the traditional durable solutions available in other refugee situations. As it happened, the conciliation commission was active only for a few years and has since been sidelined in favor of the U.S.-brokered peace processes.</p> <h2>Is the UNRWA political?</h2> <p>The UNRWA has been <a href="https://www.migrationpolicy.org/article/palestinian-refugees-dispossession">subject</a> to political headwinds since its inception and especially during periods of heightened tension between Palestinians and Israelis.</p> <p>While it is a U.N. organization and thus ostensibly apolitical, it has <a href="https://cup.columbia.edu/book/refuge-and-resistance/9780231202855">frequently been criticized</a> by Palestinians, Israelis as well as donor countries, including the United States, for acting politically.</p> <p>The UNRWA performs statelike functions across its five fields – including education, health and infrastructure – but it is restricted in its mandate from performing political or security activities.</p> <p>Initial Palestinian objections to the UNRWA stemmed from the organization’s early focus on economic integration of refugees into host states.</p> <p>Although the UNRWA officially adhered to the U.N. General Assembly’s <a href="https://www.unrwa.org/content/resolution-194">Resolution 194</a> that called for the return of Palestine refugees to their homes, U.N., U.K. and U.S. <a href="https://cup.columbia.edu/book/refuge-and-resistance/9780231202855">officials searched</a> for means by which to resettle and integrate Palestinians into host states, viewing this as the favorable political solution to the Palestinian refugee situation and the broader Israeli-Palestinian conflict. In this sense, Palestinians perceived the UNRWA to be both highly political and actively working against their interests.</p> <p>In later decades, the UNRWA <a href="https://cup.columbia.edu/book/refuge-and-resistance/9780231202855">switched its primary focus</a> from jobs to education at the urging of Palestinian refugees. But the UNRWA’s education materials were <a href="https://cup.columbia.edu/book/refuge-and-resistance/9780231202855">viewed</a> by Israel as further feeding Palestinian militancy, and the Israeli government insisted on checking and approving all materials in Gaza and the West Bank, which it has occupied since 1967.</p> <p>While Israel has <a href="https://cup.columbia.edu/book/refuge-and-resistance/9780231202855">long been suspicious</a> of the UNRWA’s role in refugee camps and in providing education, the organization’s operation, which is internationally funded, <a href="https://www.crisisgroup.org/middle-east-north-africa/east-mediterranean-mena/israelpalestine/242-unrwas-reckoning-preserving-un-agency-serving-palestinian-refugees">also saves</a> Israel millions of dollars each year in services it would be obliged to deliver as the occupying power.</p> <p>Since the 1960s, the U.S. – UNRWA’s primary donor – and other Western countries have <a href="https://cup.columbia.edu/book/refuge-and-resistance/9780231202855">repeatedly expressed their desire</a> to use aid to prevent radicalization among refugees.</p> <p>In response to the increased presence of armed opposition groups, the <a href="https://cup.columbia.edu/book/refuge-and-resistance/9780231202855">U.S. attached a provision</a> to its UNRWA aid in 1970, requiring that the “UNRWA take all possible measures to assure that no part of the United States contribution shall be used to furnish assistance to any refugee who is receiving military training as a member of the so-called Palestine Liberation Army (PLA) or any other guerrilla-type organization.”</p> <p>The UNRWA adheres to this requirement, even publishing an annual list of its employees so that host governments can vet them, but it also <a href="https://www.crisisgroup.org/middle-east-north-africa/east-mediterranean-mena/israelpalestine/242-unrwas-reckoning-preserving-un-agency-serving-palestinian-refugees">employs 30,000 individuals</a>, the vast majority of whom are Palestinian.</p> <p>Questions over the links of the UNRWA to any militancy has led to the rise of Israeli and international <a href="https://cufi.org/issue/unrwa-teachers-continue-to-support-antisemitism-terrorism-on-social-media-un-watch/">watch groups</a> that document the social media activity of the organization’s large Palestinian staff.</p> <h2>Repeated cuts in funding</h2> <p>The United States has used its money and power within the U.N. to block criticism of Israel, vetoing at least <a href="https://www.un.org/depts/dhl/resguide/scact_veto_table_en.htm">45 U.N. resolutions</a> critical of Israel.</p> <p>And the latest freeze is not the first time the U.S. has cut funding to the UNRWA or other U.N. agencies in response to issues pertaining to the status of Palestinians.</p> <p>In 2011, the <a href="https://www.reuters.com/article/idUSTRE79U5ED/#:%7E:text=WASHINGTON%20(Reuters)%20%2D%20The%20United,grant%20the%20Palestinians%20full%20membership.">U.S. cut all funding to UNESCO</a>, the U.N. agency that provides educational and cultural programs around the world, after the agency voted to admit the state of Palestine as a full member.</p> <p>The Obama administration defended the move, claiming it was required by a 1990s law to defund any U.N. body that admitted Palestine as a full member.</p> <p>But the impact of the action was nonetheless severe. Within just four years, UNESCO was <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/1758-5899.12459">forced to cut its staff in half</a> and roll back its operations. President Donald Trump later <a href="https://www.pbs.org/newshour/politics/u-s-and-israel-officially-withdraw-from-unesco">withdrew the U.S. completely from UNESCO</a>.</p> <p>In 2018, the Trump administration paused its <a href="https://www.nytimes.com/2018/08/31/us/politics/trump-unrwa-palestinians.html">US$60 million contribution to the UNRWA</a>. Trump claimed the pause would create political pressure for Palestinians to negotiate. President Joe Biden restarted U.S. contributions to the UNRWA in 2021.</p> <h2>Politicization of refugee aid</h2> <p>Palestinian are not the only group to suffer from the politicization of refugee funding.</p> <p>After World War II, states established different international organizations to help refugees but strategically excluded some groups from the refugee definition. For example, the U.S. funded the <a href="https://www.nationalww2museum.org/war/articles/last-million-eastern-european-displaced-persons-postwar-germany">U.N. Relief and Rehabilitation Administration to help resettle displaced persons after World War II</a> but resisted Soviet pressure to forcibly repatriate Soviet citizens.</p> <p>The U.S. also created a separate organization, <a href="https://academic.oup.com/ijrl/article-abstract/1/4/501/1598187">the precursor to the International Organization for Migration</a>, to circumvent Soviet influence. In many ways, the UNRWA’s existence and the exclusion of Palestinian refugees from the wider refugee regime parallels this dynamic.</p> <p>Funding for refugees has also been politicized through the earmarking of voluntary contributions to U.N. agencies. Some agencies receive funding from U.N. dues; but the UNRWA, alongside the U.N. High Commissioner for Refugees and the International Organization for Migration, receive the majority of their funding from voluntary contributions from member states.</p> <p>These contributions can be earmarked for specific activities or locations, leading to donors such as the <a href="https://www.peio.me/wp-content/uploads/2019/01/PEIO12_paper_107.pdf">U.S. or European Union dictating which refugees get aid and which do not</a>. Earmarked contributions amounted to nearly <a href="https://unsceb.org/fs-revenue-agency">96% of the UNHCR’s budget, 96% of the IOM’s budget and 74% of UNRWA funding in 2022</a>.</p> <p>As a result, any cuts to UNRWA funding will affect its ability to service Palestinian refugees in Gaza – especially at a time when so many are <a href="https://www.cnn.com/2024/01/30/middleeast/famine-looms-in-gaza-israel-war-intl/index.html">facing hunger, disease and displacement</a> as a result of war.<!-- Below is The Conversation's page counter tag.

Common car act could cost touchy drivers a hefty fine

<p>A worried driver has shared his concerns over being slapped with a potential fine after being caught holding his girlfriend's hand while driving. </p> <p>The man questioned whether the hand holding warranted a fine, after the couple passed a road safety camera in the "compromising" position. </p> <p>“Me and my girlfriend were holding hands and there was a camera on the left side, will they fine me?” the poster anonymously posted in a Facebook group for discussions about mobile phone detection camera locations in Australia.</p> <p>Online responses were varied from commenters, as many thought he driver could attract a fine as the act could be misconstrued as a more serious offence. </p> <p>One person wrote, “Was there a (mobile phone) between your hand and your girlfriends?" while another cheekily added “As long as she was just holding your hand.”</p> <p>But while some people mocked the question, others were closer to the mark, writing, “Holding her hand is no problem other than you may not have had effective control of the vehicle.”</p> <p>“Both hands on the steering wheel is my take on it,” another said.</p> <p>While police and transport authorities confirmed to <a href="https://7news.com.au/travel/driving/common-driving-act-that-could-cost-romantic-drivers-up-to-514-c-12217058" target="_blank" rel="noopener"><em>7News</em></a> that no specific rule exists for holding hands, if the hand-holding is deemed to constitute a failure to maintain proper control of a motor vehicle, that would be an offence under Australian Road Rule 297 of the Road Traffic Act 1961.</p> <p>The rule is observed nationally, but not all states fine offending motorists equally.</p> <p>Those who are caught red-handed could be fined between $215 and $514 depending on where they are.</p> <p>A Department of Transport and Main Roads spokesperson said that drivers should use their best judgement, saying, “Drivers must also drive with care and attention, as there are significant penalties for more serious offending.”</p> <p><em>Image credits: Getty Images</em></p>

Dying husband and wife spend their final days holding hands

<p>A married couple have spent their final days holding hands in hospital, after their beds were pushed next to each other so they could be side-by-side as they both passed away. </p> <p>The couple from Tennessee, Tommy and Virginia Stevens, both 91, were both admitted to the Vanderbilt hospital for unrelated medical issues. </p> <p>Tommy, who was suffering with Alzheimer’s disease, had been struck down with aspiration pneumonia and sepsis, and was transferred to the hospital's palliative care unit. </p> <p>The same morning, Virginia suffered a fall as she sustained six broken ribs, a spinal fracture, and a hip injury, and was admitted to the hospital's trauma unit. </p> <p>As Tommy and Virginia's family were struggling to split time between the two wards, hospital staff were able to pull strings for the longtime lovebirds to be roomed side-by-side.</p> <p>Virginia was moved into a room near Tommy’s in the Palliative Care Unit, and her hospital bed was scooted against his so she could comfort him as his health continued to get worse, the hospital said.</p> <p>“He was awake when she came in,” their daughter Karen Kreager said.</p> <p>“His eyes were open. He wasn’t communicating a lot — just in small whispers. But he knew that she was there and that she was going to be right beside him. They haven’t stopped holding hands the whole time. She won’t let go of him.” </p> <p>“It reminds me of why we do this work,” Mohana Karlekar, MD, medical director of VUMC’s adult Palliative Care Program told local news station <em><a href="https://www.wsmv.com/2023/09/19/she-wont-let-go-him-vanderbilt-helps-hospitalized-wife-comfort-dying-husband/" target="_blank" rel="noopener">WSMV</a></em>.</p> <p>“We take care of people — husbands, wives, mothers, fathers — not patients. We brought this family together during one of their most difficult times with little effort on our part. It involved a call, seeing an extra patient that day and some conversations.”</p> <p>“From the time we brought Mrs. Stevens over, she held her husband’s hand and fussed in a very loving way with him,” Karlekar said.</p> <p>“She was able to tell me Monday that she was at peace with what was going on, and she wanted to be there until the end.”</p> <p>Tommy died on September 8th, just a day before the couple’s 69th anniversary, and Virginia died a few days later on September 17th.</p> <p><em>Image credits: Vanderbilt University Medical Center and The Stevens Family</em></p>

Why understanding how spiders spin silk may hold clues for treating Alzheimer’s disease

<p><a href="https://theconversation.com/profiles/michael-landreh-1328287">Michael Landreh</a>, <em><a href="https://theconversation.com/institutions/karolinska-institutet-1250">Karolinska Institutet</a></em> and <a href="https://theconversation.com/profiles/anna-rising-1440132">Anna Rising</a>, <em><a href="https://theconversation.com/institutions/karolinska-institutet-1250">Karolinska Institutet</a></em></p> <p>Really, we should envy spiders. Imagine being able to make silk like they do, flinging it around to get from place to place, always having a <a href="https://pubs.acs.org/doi/10.1021/acsmacrolett.8b00678">strong-as-steel safety line</a> or spinning a comfy hammock whenever they need a rest.</p> <p>The fascinating properties of spider silk make it no wonder that scientists have been trying to unravel its secrets for decades.</p> <p>If we could understand and recreate the spinning process, we could produce artificial spider silk for a <a href="https://www.sciencedirect.com/science/article/abs/pii/S0141813021021292">range of medical applications</a>. For example, artificial silk can help <a href="https://doi.org/10.1016/j.biomaterials.2021.120692">regenerate the nerves that connect our brain and limbs</a>, and can shuttle <a href="https://doi.org/10.1021/acs.biomac.0c01138">drug molecules directly into the cells where they are needed</a>.</p> <figure><iframe src="https://www.youtube.com/embed/zNtSAQHNONo?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Spider silk is made of <a href="https://www.sciencedirect.com/topics/engineering/spidroins">proteins called spidroins</a>, which the spider stores in a silk gland in its abdomen. There are several types of spidroin for spinning different sorts of silk. Spiders <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7673682/">store them as a liquid</a> that resembles oil droplets.</p> <p>But one of the questions that has eluded scientists so far is how spiders turn these liquid droplets into silk. We decided to investigate why the spidroins form droplets, to get us closer to replicating a spider’s spinning process.</p> <h2>Weaving a web</h2> <p>The trick that spiders use to speed up their spinning process can be used to spin better artificial silk, or even develop new spinning processes.</p> <p>In 2017, we learned to <a href="https://www.nature.com/articles/ncomms15504">make synthetic silk fibres</a> by emulating the silk gland, but we did not know how things work inside the spider. Now we know that forming droplets first <a href="https://pubmed.ncbi.nlm.nih.gov/37084706/">speeds up the conversion to these fibres</a>.</p> <p>An important clue to how the droplets and fibres are related came from an unexpected area of our research – on <a href="https://pubmed.ncbi.nlm.nih.gov/23013511/">Alzheimer’s and Parkinson’s diseases</a>. Proteins that are involved in these diseases, called <a href="https://www.sciencedirect.com/topics/biochemistry-genetics-and-molecular-biology/alpha-synuclein#:%7E:text=%CE%B1%2DSynuclein%20is%20a%20highly,linked%20to%20familial%20Parkinson%20disease.">alpha-synuclein</a> and <a href="https://www.alz.org/media/Documents/alzheimers-dementia-tau-ts.pdf">tau</a>, can assemble into tiny, oil-like droplets in human cells.</p> <p>Tau is a protein that helps stabilise the internal skeleton of nerve cells (neurons) in the brain. This internal skeleton has a tube-like shape through which nutrients and other essential substances travel to reach different parts of the neuron.</p> <p>In Alzheimer’s disease, an abnormal form of tau builds up and clings to the normal tau proteins, creating “tau tangles”.</p> <p>Alpha-synuclein is found in large quantities in <a href="https://www.webmd.com/mental-health/what-is-dopamine">dopamine-producing nerve cells</a>. Abnormal forms of this protein are linked to Parkinson’s disease.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/528217/original/file-20230525-25-p40y48.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/528217/original/file-20230525-25-p40y48.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/528217/original/file-20230525-25-p40y48.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=400&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/528217/original/file-20230525-25-p40y48.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=400&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/528217/original/file-20230525-25-p40y48.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=400&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/528217/original/file-20230525-25-p40y48.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=503&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/528217/original/file-20230525-25-p40y48.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=503&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/528217/original/file-20230525-25-p40y48.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=503&amp;fit=crop&amp;dpr=3 2262w" alt="Beautiful spider web with water drops close-up" /></a><figcaption><span class="caption">The trick spiders use to speed up their spinning process can be used to spin better artificial silk.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-photo/beautiful-spider-web-water-drops-close-155560781">Aastels/Shutterstock</a></span></figcaption></figure> <p>Oil droplets of either one of these proteins form in humans when they become entangled, like boiled spaghetti on a plate. At first, the proteins are flexible and elastic, much like spidroin oil droplets.</p> <p>But if the proteins remain entangled, they get stuck together which alters their shape, changing them into rigid fibres. These can be toxic to human cells – for example, in neurodegenerative conditions such as Alzheimer’s.</p> <p>However, <a href="https://pubmed.ncbi.nlm.nih.gov/33148640/">spidroins can form droplets</a> too. This left us wondering if the same mechanism that causes neurodegeneration in humans could help the spider to convert liquid spidroins into rigid silk fibres.</p> <p>To find out, we used a <a href="https://www.nature.com/articles/nchembio.2269">synthetic spidroin called NT2RepCT</a>, which can be produced by bacteria. Under the microscope, we could see that this synthetic spidroin formed liquid droplets when it was dissolved in phosphate buffer, a type of salt found in the spider’s silk gland. This allowed us to replicate spider silk spinning conditions in the lab.</p> <h2>Silky science</h2> <p>Next, we studied how the spidroin proteins act when they form droplets. To answer this question, we turned to an analysis technique <a href="https://www.britannica.com/science/mass-spectrometry">called mass spectrometry</a>, to measure how the weight of the proteins changed when they formed droplets. To our surprise, we saw that the spidroin proteins, which normally form pairs, instead split into single molecules.</p> <p>We needed to do more work to find out how these protein droplets help spiders spin silk. Previous research has shown spidroins have different parts, called domains, with separate functions.</p> <p>The end part of the spidroin, called c-terminal domain, makes it form pairs. The c-terminal also starts <a href="https://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.1001921">fibre formation when it comes into contact with acid</a>.</p> <p>So, we made a spidroin which contained only the c-terminal domain and tested its ability to form fibres.</p> <p>When we used phosphate buffer to entangle the proteins into droplets, they turned into rigid fibre instantly.

“Pattern of bigotry”: Pauline Hanson being sued by senator over tweet

<p>Greens deputy leader Mehreen Faruqi has launched legal action against Pauline Hanson over a tweet telling her to "pack your bags and piss off back to Pakistan”.</p> <p>Documents filed in the Federal Court on May 3 allege the One Nation leader breached section 18C of the Racial Discrimination Act with the tweet in 2022.</p> <p>Faruqi is seeking a sum of $150,000 be donated to a not-for-profit or community organisation of her choice.</p> <p>She also wants Hanson to undertake anti-racism training and pay legal fees.</p> <p>Faruqi revealed in a statement that she had “taken on bullies” her whole life and had no choice but to take on Hanson.</p> <p>"I refuse to let Senator Hanson get away with racist bullying and harassment," she said.</p> <p>"Senator Hanson crossed a line when she tweeted those hateful comments and I am hoping the Federal Court puts an end to this pattern of bigotry.</p> <p>"Not just for me, but for the almost 30 per cent of Australians born overseas, and their next generations.</p> <p>"I shouldn't have to take the personal risk and trauma of taking Senator Hanson to court."</p> <p>In 2022, the Greens attempted to reprimand Hanson in the upper house but the motion was amended by the government and opposition to instead condemn all forms of racism.</p> <p>Hanson defended her comments and denied she is racist.</p> <p>Farqui said she decided to launch proceedings following Hanson’s refusal to apologise for her tweet and her rejection of conciliation attempts from the Australian Human Rights Commission.</p> <p>"Senator Hanson has used her decades in the spotlight and immense public platform to spew vicious hate towards people of colour," Faruqi said.</p> <p>"She has caused incalculable harm and gotten away with it for far too long.</p> <p>"It's time that she was held accountable.</p> <p>"Senator Hanson has been contacted for comment on the court action."</p> <p><em>Image credit: Getty/Instagram</em></p>

Can ideology-detecting algorithms catch online extremism before it takes hold?

<p>Ideology has always been a critical element in understanding how we view the world, form opinions and make political decisions. </p> <p>However, the internet has revolutionised the way opinions and ideologies spread, leading to new forms of online radicalisation. Far-right ideologies, which advocate for ultra-nationalism, racism and opposition to immigration and multiculturalism, have proliferated on social platforms.</p> <p>These ideologies have strong links with violence and terrorism. In recent years, <a href="https://www.asio.gov.au/sites/default/files/2022-02/ASIO_Annual_Report_2020-21.pdf">as much as 40%</a> of the caseload of the Australian Security Intelligence Organisation (ASIO) was related to far-right extremism. This has <a href="https://www.abc.net.au/news/2023-02-13/right-wing-terror-threat-declines-says-asio/101965964">declined</a>, though, with the easing of COVID restrictions.</p> <p>Detecting online radicalisation early could help prevent far-right ideology-motivated (and potentially violent) activity. To this end, we have developed a <a href="https://arxiv.org/abs/2208.04097">completely automatic system</a> that can determine the ideology of social media users based on what they do online.</p> <h2>How it works</h2> <p>Our proposed pipeline is based on detecting the signals of ideology from people’s online behaviour. </p> <p>There is no way to directly observe a person’s ideology. However, researchers can observe “ideological proxies” such as the use of political hashtags, retweeting politicians and following political parties.</p> <p>But using ideological proxies requires a lot of work: you need experts to understand and label the relationships between proxies and ideology. This can be expensive and time-consuming. </p> <p>What’s more, online behaviour and contexts change between countries and social platforms. They also shift rapidly over time. This means even more work to keep your ideological proxies up to date and relevant.</p> <h2>You are what you post</h2> <p>Our pipeline simplifies this process and makes it automatic. It has two main components: a “media proxy”, which determines ideology via links to media, and an “inference architecture”, which helps us determine the ideology of people who don’t post links to media.</p> <p>The media proxy measures the ideological leaning of an account by tracking which media sites it posts links to. Posting links to Fox News would indicate someone is more likely to lean right, for example, while linking to the Guardian indicates a leftward tendency. </p> <p>To categorise the media sites users link to, we took the left-right ratings for a wide range of news sites from two datasets (though many are available). One was <a href="https://reutersinstitute.politics.ox.ac.uk/our-research/digital-news-report-2018">based on a Reuters survey</a> and the other curated by experts at <a href="https://www.allsides.com/media-bias/ratings">Allsides.com</a>. </p> <p>This works well for people who post links to media sites. However, most people don’t do that very often. So what do we do about them?</p> <p>That’s where the inference architecture comes in. In our pipeline, we determine how ideologically similar people are to one another with three measures: the kind of language they use, the hashtags they use, and the other users whose content they reshare.</p> <p>Measuring similarity in hashtags and resharing is relatively straightforward, but such signals are not always available. Language use is the key: it is always present, and a known indicator of people’s latent psychological states. </p> <p>Using machine-learning techniques we found that people with different ideologies use different kinds of language. </p> <p>Right-leaning individuals tend to use moral language relating to vice (for example, harm, cheating, betrayal, subversion and degradation), as opposed to virtue (care, fairness, loyalty, authority and sanctity), more than left-leaning individuals. Far-right individuals use grievance language (involving violence, hate and paranoia) significantly more than moderates. </p> <p>By detecting these signals of ideology, our pipeline can identify and understand the psychological and social characteristics of extreme individuals and communities.</p> <h2>What’s next?</h2> <p>The ideology detection pipeline could be a crucial tool for understanding the spread of far-right ideologies and preventing violence and terrorism. By detecting signals of ideology from user behaviour online, the pipeline serves as an early warning systems for extreme ideology-motivated activity. It can provide law enforcement with methods to flag users for investigation and intervene before radicalisation takes hold.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/can-ideology-detecting-algorithms-catch-online-extremism-before-it-takes-hold-200629" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Novak Djokovic holds no grudge against Australia

<p>Novak Djokovic says he still has plenty of love and admiration for Australia, despite being deported due to the vaccine mandates.</p> <p>Djokovic says he received the reception he wished for in his triumphant return to singles action in Australia.</p> <p>Djokovic booked a spot in the second round of the Adelaide International 1 with a thumping 6-3 6-2 win over Frenchman Constant Lestienne on Tuesday.</p> <p>It was his first singles match in Australia since being deported in January 2022 for refusing to have the COVID-19 vaccine.</p> <p>The 21-time grand slam champion received a rousing reception when he stepped out on court on Tuesday, and he didn’t disappoint his adoring fans.</p> <p>Djokovic’s power, court speed, and deft work at the net proved too much to handle for Lestienne, with the match lasting just 74 minutes.</p> <p>The world No.5, who lost his low-key doubles match on Monday, repeatedly touched his heart before signalling to the crowd and the sky upon winning his singles match.</p> <p>He also kissed his hand and touched the court, later saying he was delighted to be back in the country where he’s won nine of his 21 grand slam trophies.</p> <p>“I’m glad to be back in Australia,” Djokovic said in his post-match on-court interview.</p> <p>“Thank you all for coming out today. Thank you for giving me the welcome that I could only wish for.</p> <p>“Over the years, Australia has been the place where I’ve played my best tennis, without a doubt.</p> <p>“If I have to pick one country where I’ve had the most success, which treated me in the best way in terms of tennis, it’s here, definitely.</p> <p>“Even the circumstances last year, it wasn’t easy for anybody. But I’m just happy to be here focusing on tennis, and enjoying my time with you guys.”</p> <p>The result sets up a round of 16 clash with Frenchman Quentin Halys, who defeated Australian Jordan Thompson in straight sets on Monday. Djokovic lost only five points on serve during the opening set, but did have to save a break point in the fifth game.</p> <p><em>Image: Getty</em></p>

Super funds should use their substantial holdings for public good

<p>Last month Federal Treasurer Jim Chalmers unveiled the <a href="https://theconversation.com/albanese-governments-first-budget-delivers-election-promises-but-forecasts-soaring-power-prices-192844">National Housing Accord</a>, intended to build a million new homes in Australia. Part of the plan is to encourage superannuation funds to invest in social and affordable housing. </p> <p>The proposal was met with <a href="https://www.theage.com.au/money/super-and-retirement/only-if-the-return-stacks-up-super-funds-will-demand-sweeteners-to-back-labor-housing-plan-20221028-p5btsq.html">criticism</a> from some quarters, with <a href="https://www.macrobusiness.com.au/2022/09/hey-labor-hands-off-our-superannuation-savings/">critics arguing</a>Australia’s superannuation savings belongs to its members, "it is their money, not Labor’s play money."</p> <p>These critics are forgetting it was not so long ago people’s taxes (which can also be seen as “their” money) paid everyone’s pensions. And while in consolidated revenue on their way to keeping us in comfort in our old age, these taxes helped build extensive public and social infrastructure.</p> <p>The transfer of retirement funding from the national government to non-government super funds is just one example of the shift from public provision of social goods towards individual accumulation that has defined Australian politics for four decades. This shift, along with associated income tax cuts, has contributed directly to the housing affordability crisis via the emphasis on property as an investment. </p> <p>Australia’s super funds now control <a href="https://www.superannuation.asn.au/resources/superannuation-statistics">$3.3 trillion</a> – the <a href="https://treasury.gov.au/publication/p2020-super">fourth-largest pool</a> of retirement savings in the world. </p> <p>Most of them invest in <a href="https://www.marketforces.org.au/superfunds/">fossil fuels</a> and some, directly or indirectly, in <a href="https://novowealth.com.au/the-dirty-dozen-part-3/">armaments</a>, exploited labour and old-growth logging. All of them invest <a href="https://www.investordaily.com.au/superannuation/50298-super-funds-continue-shift-to-international-investments">internationally</a>where, if they are not doing actual harm, they are still not doing any good for their members in Australia beyond delivering financial returns.</p> <p>Super funds are regulated by federal legislation which originally stipulated they must act in the “<a href="https://theconversation.com/labor-is-winding-back-reforms-meant-to-hold-super-funds-accountable-to-their-members-187594">best interests of their members</a>”. This was changed by the Coalition government in 2020 to read “<a href="https://archive.budget.gov.au/2020-21/factsheets/download/your_future_your_super_factsheet.pdf">best financial interests</a>”. It is this requirement that has the critics of Chalmers’ plan <a href="https://grattan.edu.au/news/super-funds-cant-solve-our-affordable-housing-problem/">baulking</a>: how can it be in members’ best financial interests to invest in social housing?</p> <h2>Why super funds should invest in social housing</h2> <p>If even 1% of the $3 trillion – $30 billion – were invested in social housing, rental pressures in the private housing market would be massively reduced as tens of thousands of households currently in the private rental market vacated those dwellings for new social housing. </p> <p>The flow-on effects of decent secure housing, including improvements in physical and mental health, and general social welfare are <a href="https://journals.sagepub.com/doi/full/10.1177/08854122211012911">well</a> <a href="https://www.ahuri.edu.au/sites/default/files/migration/documents/Final-Report-Trajectories-the-interplay-between-housing-and-mental-health-pathways.pdf">documented</a>. </p> <p>The Albanese government could re-amend the regulations to their earlier form, and could require all super funds to invest a proportion of their portfolios in socially and ethically beneficial activities.</p> <p>Super fund members are workers and members of society too, making up most of the adult population. They would all benefit from a more equal society. </p> <h2>Investing for social good is already happening</h2> <p>Some local funds and other financial institutions are already investing in social goods. Various super funds like <a href="https://www.cbussuper.com.au/super/my-investment-options/investing-in-australia#:%7E:text=Cbus%20Super%27s%20social%20and%20affordable%20housing%20investment&amp;text=The%20Fund%20has%20been%20a,more%20social%20and%20affordable%20housing.">CBus</a> and community banks like <a href="https://bankaust.com.au/impact-finance/inclusive-and-accessible-housing">Bank Australia</a>invest in or give low-interest loans to community housing associations. Australian Super has a 25% stake in <a href="https://assemblecommunities.com/australiansuper-makes-cornerstone-investment-in-assemble-communities/">Assemble</a>, an affordable housing developer – bought before the 2020 amendment.</p> <p>They are taking small steps in a direction that is well-established in many European countries, where the notion of corporate responsibility has much greater resonance. This can be seen in the German constitution, which stipulates property ownership entails obligations, and “<a href="https://www.deutschland.de/en/topic/politics/the-german-basic-law-article-14-property-and-the-right-of-inheritance-shall-be">its use shall also serve the public good</a>.”</p> <p>European funds are finding low-yielding, slow-returning investments in social and co-operative housing complement their diverse portfolios well. Germany’s <a href="https://www.umweltbank.de/_Resources/Persistent/3/8/c/c/38ccacb3aabab0e602c8da17624d59d40b4b385f/20220705_UmweltBank_Anno_engl.pdf">UmweltBank</a> supports various housing initiatives including the famous <a href="https://www.umweltbank.de/2019/sauber-finanziert/wohnprojekt-spreefeld">Spreefeld co-op</a> in Berlin, which provides a steady, low-risk return. </p> <p>Investments in social housing are regarded as the lowest risk of all, as rents are mostly paid from financial assistance guaranteed by the state. Pension funds and community banks can commit to the long term, unlike <a href="https://overland.org.au/2021/12/vulture-landlords-and-the-justice-washing-of-housing-struggle/comment-page-1/#comment-1060442">corporate investors</a> that purchase social housing for a limited period before selling it on the private market.</p> <p>Oversight of these initiatives must be careful and regulated, but there is no reason why they should not be implemented. Chalmers’ plan should be applauded, and could go much further.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/super-funds-should-use-their-substantial-holdings-for-public-good-194443" target="_blank" rel="noopener">The Conversation</a>. </em></p>

"Help me": Bunnings thief dies after security guard's headlock hold

<p>After stealing a gas cylinder and saw blade from a Melbourne Bunnings store, Anthony Georgiou was placed in a headlock hold by security contractors. </p> <p>The security team tried to stop him from fleeing the Frankston store, while a witness heard Georgiou scream, "Help me, help me, let me go," as he was wrangled to the ground. </p> <p>the store’s sub-contracted loss prevention officers (LPOs) continued to restrain the 31-year-old, despite his clear distress, until he fell unconscious. </p> <p>Georgiou was taken to hospital where he died later that day. </p> <p>A Victorian coroner has found Georgiou’s death in September 2016 would not have occurred if he was not restrained by the contractors at Bunnings.</p> <p>“There seems little doubt that had Georgiou not been involved in the struggle ... he would have walked away from Bunnings that day,” coroner Darren Bracken said in his findings, which were released earlier this week. </p> <p>Forensic pathologist Heinrich Bouwer, who conducted Georgiou’s autopsy, found his death was caused by complications with methylamphetamine use in a setting of physical restraint.</p> <p>He told an inquest being put in a headlock at Bunnings had caused injuries that inhibited Georgiou’s breathing.</p> <p>The security officers told the inquest they initially tried to get Georgiou to take the stolen property back to the store, but he became aggressive and said “no f*** off” and walked away from them.</p> <p>One of the officers said he grabbed Georgiou, near the exit, told him he was under arrest and said “let’s make it easy and come back with us”, but he was ignored, and the physical altercation began. </p> <p>The coroner also found that the security guards in question had not attended the mandatory training on how to deal with thieves, nor been given a copy of the Bunnings' code of conduct.</p> <p><em>Image credits: Getty Images / A Current Affair</em></p>

James Caan was rarely a star. But he was a remarkable actor’s actor who could hold his own among the greats

<p>James Caan, who died on July 6 at 82, was one of those actors who wouldn’t attract mass audiences to a movie just because he was in it. He wasn’t a “star” in the same way we see his contemporaries such as Jack Nicholson, Jane Fonda, Al Pacino or Robert De Niro.</p> <p>In essence, Caan was an actor’s actor. He never cared for the trappings of stardom or desired the celebrity status so many other actors craved. He was into acting for one thing: the craft.</p> <p>In the 1960s, actors were experimenting with their craft just as much as the youth culture around them was experimenting with drugs, art, music and writing. A new generation of actors was emerging who were wildly different from their predecessors, influenced by Lee Strasberg’s <a href="https://theconversation.com/from-the-moscow-stage-to-monroe-and-de-niro-how-the-method-defined-20th-century-acting-179088" target="_blank" rel="noopener">method acting</a>. Caan signed up for classes at the Neighborhood Playhouse School of Theatre in New York, where he learned the Method and stayed for five years.</p> <p>Caan’s years at the Playhouse School developed in him the urge to be seen as a serious actor, rather than a “star”. When offered a leading role in a television series in 1965 he <a href="https://www.proquest.com/docview/155268288" target="_blank" rel="noopener">turned it down</a>, fearful the role would make him rich and diminish his love of acting.</p> <p>This was the thing with Caan. He couldn’t be typecast. De Niro has always traded on his tough-guy image; Pacino, the outsider; Nicholson, crazy and cool. But Caan couldn’t be put in a box. You had the volatile, violent son in The Godfather (1972), the zany comedy police detective in Freebie and the Bean (1974), the passive victim in Misery (1990), and the uptight, reserved father in Elf (2003).</p> <p>He was a <a href="https://www.imdb.com/name/nm0001001/" target="_blank" rel="noopener">prolific actor</a>, but rarely the lead. This took nothing away from his performances, but it highlights how uninterested he was in stardom. His quality as an actor lies in how he was able to turn these smaller roles into his own. When he was on screen, you knew he was there. He demanded attention.</p> <p>He owned those characters. No role was too small for his light to shine through.</p> <p>Even when playing a smaller role, he had the ability to eclipse the leads. Perhaps nothing shows this better than his role as Sonny Corleone in The Godfather. Caan is explosive. He almost jumps out of the screen with his frenetic energy, and deservedly gained a best supporting actor Oscar nomination along with Pacino – although Caan had much less screen time.</p> <h2>Life imitates art</h2> <p>Caan’s personal life was as dramatic as his on-screen characters.</p> <p>Linked to <a href="https://radaronline.com/p/james-caan-gambling-ring-illegal-betting-death/" target="_blank" rel="noopener">Mafia groups</a> and periods of <a href="https://www.independent.ie/entertainment/books/james-caan-the-reformed-character-actor-26256800.html" target="_blank" rel="noopener">drug addiction</a>, he had phone calls tapped <a href="https://www.theguardian.com/film/2022/jul/08/james-caan-obituary" target="_blank" rel="noopener">by the FBI</a> and had numerous <a href="https://www.latimes.com/archives/la-xpm-1994-03-12-me-33226-story.html" target="_blank" rel="noopener">run-ins</a> with the law.</p> <p>The death of his sister – also his manager – <a href="https://www.pearlanddean.com/james-caan-struggling-to-find-roles-to-crown-his-career/" target="_blank" rel="noopener">affected him greatly</a>. The theft of his money by a <a href="https://www.latimes.com/archives/la-xpm-1990-11-29-ca-7423-story.html" target="_blank" rel="noopener">dodgy accountant</a> left him penniless for a while.</p> <p>As a result of his ongoing troubles, especially into the 1980s, Caan’s career faltered. There are large gaps in his acting resume where little happened for him. Hollywood didn’t lock him out, but it didn’t go looking for him either.</p> <p>It is interesting to think of the roles Caan could have had and what he would have brought to them.</p> <p>He was considered for or offered the leads in Kramer Vs Kramer, One Flew Over the Cuckoo’s Nest, Blade Runner, Star Wars and even the <a href="https://comicbookmovie.com/superman/james-caan-talks-about-passing-on-superman-star-wars-badmouths-harrison-ford-a87726#gs.60qihy" target="_blank" rel="noopener">1970s Superman</a>. But for all he either refused or was passed over.</p> <p>The 1990s and 2000s saw him return to steady work. Supporting roles in features and starring roles in lesser television movies became more prolific.</p> <p>In these later productions, you could still see the glimmer of greatness in the ageing Caan’s work. Occasionally, in dramas such as The Yards (2000), City of Ghosts (2002) and Dogville (2003), we witness a resurgence of Caan’s energy and intensity back on the screen.</p> <p>His longevity as an actor, rather than as a “star”, through his six-decade career came down to his versatility. He was noticeable, without having that star recognition.</p> <p>Perhaps that was a blessing in disguise and his secret weapon as an actor. When we see a famous actor we see the “star” first and the actor second. With Caan we see the actor – and acting – first. He was able to transform into whatever character he was playing and make his audience believe he was that role, free from the artifice of stardom.</p> <p>Caan did not have a particularly stellar career compared with some of his contemporaries. But that is immaterial. He was a remarkable actor who, at his best, could hold his own among the greats.</p> <p><em><strong>This article originally appeared on <a href="https://theconversation.com/james-caan-was-rarely-a-star-but-he-was-a-remarkable-actors-actor-who-could-hold-his-own-among-the-greats-186635" target="_blank" rel="noopener">The Conversation</a>.</strong></em></p> <p><em>Image: Shutterstock</em></p>

It covers entire mountain ranges beneath it.</p> <p>The ice sheet “<a href="https://vimeo.com/133626869" target="_blank" rel="noopener">flows</a>” over the land from the Antarctic interior and towards the surrounding ocean. As a whole it remains a solid mass, but its shape slowly deforms as the ice crystals move around.</p> <p>While the ice sheet flows outward, snowfall from above replenishes it. This cycle is supposed to keep the system in balance, wherein balance is achieved when the ice sheet is gaining the same amount of ice as it’s losing to the ocean each year.</p> <p>However, <a href="https://climate.nasa.gov/vital-signs/ice-sheets/" target="_blank" rel="noopener">satellites</a> keeping watch from above show the ice sheet is currently not in balance. Over the past 40 years, it has lost more ice than it has gained. The result has been global rising sea levels.</p> <p>But these historical observations span only four decades, limiting our understanding of how the ice sheet responds to climate change over much longer periods.</p> <p>We wanted to look further back in time – before satellites – and even before the first polar explorers. For this, we needed natural archives.</p> <h2>Digging up Antarctica’s past</h2> <p>We brought together various natural archives to unearth how the Antarctic ice sheet changed over the past 10,000 years or so. These included:</p> <ul> <li>ice cores collected from Antarctica’s remote interior, which can show us how snow accumulated in the past</li> <li>rocks collected from exposed mountain peaks, which reveal how the ice sheet has thickened or thinned with time</li> <li>sediment cores collected from the seafloor, which reveal how the ice sheet margin – where the edge of the land ice meets the ocean – advanced or retreated</li> <li>lake mud and old beaches, which reveal how the coastline changed in response to the ice sheet growing or shrinking.</li> </ul> <p>When we started our research, I wasn’t sure what to expect. After all, this period of time was long considered fairly dull, with only small changes to the ice margin.</p> <p>Nevertheless, we studied the many different natural archives one by one. The work felt like a 1,000-piece jigsaw puzzle, full of irregular-shaped pieces and seemingly no straight edge. But once we put them together, the pieces lined up and the picture was clear.</p> <p>Most striking was a period of ice loss that took place in all regions of Antarctica about 10,000 to 5,000 years ago. It resulted in many metres of sea-level rise globally.</p> <p>In some regions of Antarctica, however, this ice loss was then followed by ice gain during the past 5,000 years – and a corresponding global sea-level fall – as the ice sheet margin advanced to where it is today.</p> <h2>A warning</h2> <p>Understanding how and why the Antarctic ice sheet changed in this fashion offers lessons for the future.</p> <p>The first lesson is more of a warning. The period of ice loss from 10,000 to 5,000 years ago was rapid, occurring at a similar rate to the most dramatically changing parts of the Antarctic ice sheet today.</p> <p>We think it was likely the result of warm ocean water melting the underside of floating ice shelves – something that has also happened in recent decades. These ice shelves hold back the ice on land, so once they’re removed the ice on the land flows faster into the ocean.</p> <p>In the future, it’s predicted ice loss will <a href="https://youtu.be/XRUxTFWWWdY?t=149" target="_blank" rel="noopener">accelerate</a> as the ice sheet retreats into basins below sea level. This may already be under way in some regions of Antarctica. And based on what happened in the past, the resulting ice loss could persist for centuries.</p> <h2>Bouncing back</h2> <p>The second lesson from our work may bring some hope. Some 5,000 years ago the ice sheet margin stopped retreating in most locations, and in some regions actually started to advance. One explanation for this relates to the previous period of ice loss.</p> <p>Before the ice began melting away, the Antarctic ice sheet was much heavier, and its weight pushed down into the Earth’s crust (which sits atop a molten interior). As the ice sheet melted and became lighter, the land beneath it would have lifted up – effectively hauling the ice out of the ocean.</p> <p>Another possible explanation is climate change. At Antarctica’s coastal fringe, the ocean may have temporarily switched from warmer to cooler waters around the time the ice sheet began advancing again. At the same time, more snowfall took place at the top of the ice sheet.</p> <p>Our research supports the idea that the Antarctic ice sheet is poised to lose more ice and raise sea levels – particularly if the ocean continues to warm.</p> <p>It also suggests uplift of the land and increased snowfall have the potential to slow or offset ice loss. However, this effect is not certain.</p> <p>The past can never be a perfect test for the future. And considering the planet is <a href="https://www.ipcc.ch/report/ar6/wg1/downloads/report/IPCC_AR6_WGI_SPM.pdf" target="_blank" rel="noopener">warming faster</a> now than it was back then, we must err on the side of caution.</p> <p><em><strong>This article originally appeared on <a href="https://theconversation.com/we-studied-how-the-antarctic-ice-sheet-advanced-and-retreated-over-10-000-years-it-holds-warnings-for-the-future-185505" target="_blank" rel="noopener">The Conversation</a>.</strong></em></p> <p><em>Image: Shutterstock</em></p>

Has COVID affected your sleep?

<p>During the early phases of the pandemic, and especially during lockdowns and stay-at-home orders, many people reported disruptions to sleep and their sleeping patterns. As COVID infections have increased, we’re again seeing reports of people experiencing poor sleep during and following COVID infection.</p> <p>Some people report insomnia symptoms, where they struggle to fall or stay asleep, with this commonly being referred to as “coronasomnia” or “COVID insomnia”. Others report feeling constantly fatigued, and seemingly can’t get enough sleep, with this sometimes being referred to as “long COVID”.</p> <p>So why is our sleep impacted by COVID infections, and why do the impacts differ so much between individuals?</p> <h2>Sleep and immunity</h2> <p>When our body is infected with a virus this causes an immune, or inflammatory response. As part of this response, our cells produce proteins such as cytokines in order to help fight the infection. Some of these cytokines are also involved in promoting sleep and are known as “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2605347/#!po=3.12500" target="_blank" rel="noopener">sleep regulatory substances</a>”. In this way, when there are more of these cytokines in our bodies this tends to make us sleepier.</p> <p>It gets a little more complicated though, because like many things, sleep and immunity are bidirectional. This means sleep, in particular poor sleep, can impact immune function, and immune function can impact sleep. During sleep, especially during the non-rapid eye movement stage slow wave sleep (a deep stage of sleep), there is an <a href="https://www.nature.com/articles/s41577-019-0190-z" target="_blank" rel="noopener">increase in the production of some cytokines</a>. As such, sleep increases the immune response which may increase our chance of survival from the infection.</p> <h2>Sleep and COVID</h2> <p>While we are still learning about the specific effects of COVID on sleep, we do know about what happens to sleep with other viral infections.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/11134688/" target="_blank" rel="noopener">One study</a> that looked at rhinovirus infections, or the “common cold”, in healthy adults, found individuals who are symptomatic had a reduced sleep duration, less consolidated sleep, and poorer cognitive performance than asymptomatic individuals.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/30742884/" target="_blank" rel="noopener">Another study</a> that looked at people with respiratory infections showed that while symptomatic, people spent more time in bed and had increased sleep time, yet had more awakenings during sleep. People also reported increased difficulties falling asleep, poorer sleep quality, more restless sleep and more “lighter” sleep.</p> <p><a href="https://www.frontiersin.org/articles/10.3389/fpubh.2021.795320/full#B15" target="_blank" rel="noopener">A more recent study</a> found patients with COVID reported more trouble sleeping compared to patients without COVID.</p> <h2>COVID insomnia and long COVID</h2> <p>While the changes in sleep with viral infections such as COVID are likely to be due to our bodies’ immune response, it’s possible the sleep disturbances, such as the fragmented sleep and waking frequently, may lead to poor sleep habits, such as using phones or electronic devices at night.</p> <p>Poorer night time sleep may also lead to some people having more frequent daytime naps, which could further impact night time sleep. And taking longer to fall asleep, or waking up at night and struggling to fall back asleep can lead to frustrations around not being able to sleep.</p> <p>All of these factors, either independently or in combination with each other, may lead to the insomnia symptoms people with COVID are experiencing. In the short-term, these insomnia symptoms are not really a big issue. However, if poor sleep habits persist this can lead to <a href="https://theconversation.com/explainer-what-is-insomnia-and-what-can-you-do-about-it-36365" target="_blank" rel="noopener">chronic insomnia</a>.</p> <p>On the other side, there are people who experience long COVID, where they are constantly fatigued even though they may be getting sufficient sleep well after their COVID infection has passed. Unfortunately, more research is needed to determine why some people experience lingering fatigue after viral infections, but it may be due to an excessive immune response.</p> <p>Factors such as <a href="https://academic.oup.com/sleep/article/45/Supplement_1/A321/6592670" target="_blank" rel="noopener">genetics, other health concerns and mood disorders</a> such as anxiety are the likely culprits as to why some people experience “COVID insomnia”, whereas others are more likely to develop “long COVID”. Much more research is needed to fully understand the causes of poorer sleep with COVID.</p> <h2>How to deal with sleep disruptions caused by COVID</h2> <p>During the acute phase of infections, it’s important to accept we may experience some sleep disturbances. Try not to get too frustrated about sleeping poorly or taking longer to fall asleep.</p> <p>When you start to feel better, aim to go back to your regular, pre-COVID, sleep-wake pattern, and avoid daytime napping, or at least too much daytime napping. Try to avoid looking at the clock when in bed, and go to bed when you feel sleepy. Reduce light exposure at night, and aim to get some bright light in the morning, ideally outdoors. This will help you get back to a normal routine faster.</p> <p>For more tips on how to improve sleep and to avoid chronic insomnia, the <a href="https://www.sleephealthfoundation.org.au/resources/covid19-resources.html" target="_blank" rel="noopener">Sleep Health Foundation</a> has some resources specifically dedicated to COVID and sleep. If you’re still struggling with insomnia or excessive sleepiness following a COVID infection, especially if it’s been a few months, it’s always good to see your GP, who can offer you more specific advice and work out if more testing is required.</p> <p><em><strong>This article originally appeared on <a href="https://theconversation.com/has-covid-affected-your-sleep-heres-how-viruses-can-change-our-sleeping-patterns-184323" target="_blank" rel="noopener">The Conversation</a>.</strong></em></p> <p><em>Image: Shutterstock</em></p>

Qantas passengers left fuming on hold

<p dir="ltr">Customers have been left fuming after being kept on hold for 8.5 hours with Qantas. </p> <p dir="ltr">Despite borders being open for a while now, flyers are still confused about what is needed with travelling such as masks, vaccinations and isolating. </p> <p dir="ltr">Katrina was one of those confused passengers who said she is embarrassed at having to wait on hold for an excruciating 8.5 hours with Qantas. </p> <p dir="ltr">“I took the call to a meeting, I took the call to an eatery,” Katrina told 2GB.</p> <p dir="ltr">“It was a two-hour meeting and we had the music playing in the background the whole time.”</p> <p dir="ltr">Others took to Twitter to share their horror hold-time stories, saying it is unacceptable to wait that long.</p> <p dir="ltr">“I was on hold for 6hrs 46mins and the customer service agent cut me off. This is easily the worst customer service I’ve experienced - all while trying to fix an error Qantas has made on a booking!! So unacceptable,” someone wrote.</p> <p dir="ltr">“@Qantas total of 6 hours on hold across 2 calls with no answer. Almost $750 taken from my account with no flight to show for it, $300 locked up in your "Qantas pass". Still unresolved. Australia's worst airline for sure,” another commented.</p> <p dir="ltr">“Three HOURS on hold @Qantas what world are we living in?” someone asked.</p> <p dir="ltr">“Hey @qantas I’ve made four phone calls over the past week and been on hold for over 10 hours in total and I’m still waiting to hear back from you,” another comment read.</p> <p dir="ltr">Qantas chief customer officer Stephanie Tully apologised to customers and said they are looking to fix the issue. </p> <p dir="ltr">“I want to sincerely apologise to our customers, the wait times are not acceptable at all and it is our top priority to fix this,” Ms Tully said.</p> <p dir="ltr"><em>Images: Twitter</em></p>
