Outrage after renters confronted with cleaning “scoring system”

An Australian real estate agent has come under fire for their “demoralising” scoring system for tenants during routine inspections. One fired up renter said they were shocked to receive a scorecard from the agent after they complied with an inspection, and shared their feedback on Reddit. The scorecard rated the tenant’s efforts cleaning the property in 17 different rooms and areas, marking them on cleanliness, and if the areas were damaged or required maintenance. The renter was then also given an overall rating out of five stars, based on the upkeep of their rental home. The Reddit user showed that they received just three and half stars, despite being marked down in only one area due to a light globe not working. In their post, the tenant said they had made every effort to clean the home, adding that the rating was “demoralising”. “I’ve been renting a long time, and my deep cleaning routine is based around inspections,” they explained. “I go all out - every room in my little 3x2 villa is given a spring clean, every surface is washed including walls, doors, lights, windows, carpets etc.” “Had my latest inspection a few weeks ago and just received the report. Despite the agent commenting once again that she never sees houses as clean as mine, and taking 112 (!) photos of every single thing that shows how great the condition of the house is - having one light globe not working is so terrible that I’m scored three and a half out of five.” The renter went on to say that they had only recently discovered that the broken light globe was the real estate’s responsibility to replace, and does not warrant such a severe marking down in their “score”. “The globe in question is a downlight fitting. We have so many downlights that I don’t even use this particular one,” they continued. “I can’t replace the globe itself, I need to get into the roof to replace the whole unit. Thanks to people here I’ve learned this isn’t even my responsibility to fix!” The renter’s post sparked a huge outrage online, with many up in arms over the current state of the rental market and unrealistic expectations of estate agents. One person said, “I fully believe that the average renter keeps a home to a higher standard than an owner, and it seems deliberately demoralising that someone could be marked down for having a light out.” Another added, “This is ridiculously petty, and more importantly, totally irrelevant to the purpose of a periodic inspection. Which is to identify whether any maintenance is needed.” A third person took their anger out on the entire system, summing it up by writing, “I sort of wonder what little lightbulb clicks in your mind and you wake up one day and ask yourself, ‘How can I be a massive c*** who offers no value to society? I know! I will get into real estate.’” Image credits: Getty Images / Reddit

Did COVID harm my immune system?

So you’ve had COVID and have now recovered. You don’t have ongoing symptoms and luckily, you don’t seem to have developed <a href="https://theconversation.com/long-covid-how-researchers-are-zeroing-in-on-the-self-targeted-immune-attacks-that-may-lurk-behind-it-169911" target="_blank" rel="noopener">long COVID</a>. But what impacts has COVID had on your overall immune system? It’s early days yet. But growing evidence suggests there are changes to your immune system that may put you at risk of other infectious diseases. Here’s what we know so far. <h2>A round of viral infections</h2> Over this past winter, many of us have had what seemed like a <a href="https://theconversation.com/why-do-i-and-my-kids-get-so-many-colds-and-with-all-this-covid-around-should-we-be-isolating-too-179302" target="_blank" rel="noopener">continual round</a> of viral illness. This may have included COVID, <a href="https://www.who.int/health-topics/influenza-seasonal#tab=tab_1" target="_blank" rel="noopener">influenza</a> or infection with <a href="https://www.mayoclinic.org/diseases-conditions/respiratory-syncytial-virus/symptoms-causes/syc-20353098" target="_blank" rel="noopener">respiratory syncytial virus</a>. We may have recovered from one infection, only to get another. Then there is the re-emergence of infectious diseases globally such as <a href="https://theconversation.com/we-need-to-talk-about-monkeypox-without-shame-and-blame-188295" target="_blank" rel="noopener">monkeypox</a> or <a href="https://theconversation.com/the-latest-polio-cases-have-put-the-world-on-alert-heres-what-this-means-for-australia-and-people-travelling-overseas-188989" target="_blank" rel="noopener">polio</a>. Could these all be connected? Does COVID somehow weaken the immune system to make us more prone to other infectious diseases? There are <a href="https://www.sciencedirect.com/science/article/pii/B9780128009475000168?via%3Dihub" target="_blank" rel="noopener">many reasons</a> for infectious diseases to emerge in new locations, after many decades, or in new populations. So we cannot jump to the conclusion COVID infections have given rise to these and other viral infections. But evidence is building of the negative impact of COVID on a healthy individual’s immune system, several weeks after symptoms have subsided. <h2>What happens when you catch a virus?</h2> There are three possible outcomes after a viral infection: 1) your immune system clears the infection and you recover (for instance, with <a href="https://www.healthychildren.org/English/health-issues/conditions/ear-nose-throat/Pages/Rhinovirus-Infections.aspx" target="_blank" rel="noopener">rhinovirus</a> which causes the common cold) 2) your immune system fights the virus into “latency” and you recover with a virus dormant in our bodies (for instance, <a href="https://www.healthdirect.gov.au/chickenpox" target="_blank" rel="noopener">varicella zoster virus</a>, which causes chickenpox) 3) your immune system fights, and despite best efforts the virus remains “chronic”, replicating at very low levels (this can occur for <a href="https://www.who.int/news-room/fact-sheets/detail/hepatitis-c" target="_blank" rel="noopener">hepatitis C virus</a>). Ideally we all want option 1, to clear the virus. In fact, most of us <a href="https://biosignaling.biomedcentral.com/articles/10.1186/s12964-022-00856-w" target="_blank" rel="noopener">clear SARS-CoV-2</a>, the virus that causes COVID. That’s through a complex process, using many different parts of our immune system. But international evidence suggests changes to our immune cells after SARS-CoV-2 infection may have other impacts. It may affect our ability to fight other viruses, as well as other pathogens, such as bacteria or fungi. <h2>How much do we know?</h2> An <a href="https://bmcmedicine.biomedcentral.com/articles/10.1186/s12916-021-02228-6" target="_blank" rel="noopener">Australian study</a> has found SARS-CoV-2 alters the balance of immune cells up to 24 weeks after clearing the infection. There were changes to the relative numbers and types of immune cells between people who had recovered from COVID compared with healthy people who had not been infected. This included changes to cells of the <a href="https://www.khanacademy.org/test-prep/mcat/organ-systems/the-immune-system/a/innate-immunity" target="_blank" rel="noopener">innate immune system</a> (which provides a non-specific immune response) and the <a href="https://www.ncbi.nlm.nih.gov/books/NBK21070/" target="_blank" rel="noopener">adaptive immune system</a> (a specific immune response, targeting a recognised foreign invader). <a href="https://journals.plos.org/plospathogens/article?id=10.1371/journal.ppat.1009742" target="_blank" rel="noopener">Another study</a> focused specifically on <a href="https://www.immunology.org/public-information/bitesized-immunology/cells/dendritic-cells" target="_blank" rel="noopener">dendritic cells</a> – the immune cells that are often considered the body’s “first line of defence”. Researchers found fewer of these cells circulating after people recovered from COVID. The ones that remained were less able to activate white blood cells known as <a href="https://www.britannica.com/science/T-cell" target="_blank" rel="noopener">T-cells</a>, a critical step in activating anti-viral immunity. Other studies have found different impacts on T-cells, and other types of white blood cells known as <a href="https://askabiologist.asu.edu/b-cell" target="_blank" rel="noopener">B-cells</a> (cells involved in producing antibodies). After SARS-CoV-2 infection, one study <a href="https://doi.org/10.1172/JCI140491" target="_blank" rel="noopener">found evidence</a> many of these cells had been activated and “exhausted”. This suggests the cells are dysfunctional, and might not be able to adequately fight a subsequent infection. In other words, sustained activation of these immune cells after a SARS-CoV-2 infection may have an impact on other inflammatory diseases. <a href="https://www.nature.com/articles/s41392-021-00749-3#citeas" target="_blank" rel="noopener">One study</a> found people who had recovered from COVID have changes in different types of B-cells. This included changes in the cells’ metabolism, which may impact how these cells function. Given B-cells are critical for producing antibodies, we’re not quite sure of the precise implications. Could this influence how our bodies produce antibodies against SARS-CoV-2 should we encounter it again? Or could this impact our ability to produce antibodies against pathogens more broadly – against other viruses, bacteria or fungi? The study did not say. <h2>What impact will these changes have?</h2> One of the main concerns is whether such changes may impact how the immune system responds to other infections, or whether these changes might worsen or cause other chronic conditions. So more work needs to be done to understand the long-term impact of SARS-CoV-2 infection on a person’s immune system. For instance, we still don’t know how long these changes to the immune system last, and if the immune system recovers. We also don’t know if SARS-CoV-2 triggers other chronic illnesses, such as <a href="https://www.healthdirect.gov.au/chronic-fatigue-syndrome-cfs-me" target="_blank" rel="noopener">chronic fatigue syndrome</a> (myalgic encephalomyelitis). Research into this is ongoing. What we do know is that having a healthy immune system and being vaccinated (when a vaccine has been developed) is critically important to have the best chance of fighting any infection.

AI system sees beyond the frame of famous artworks

A new AI tool can provide a glimpse of what could potentially be going on beyond the frame of famous paintings, giving them a brand new life. OpenAI, a San Francisco-based company, has created a new tool called 'Outpainting' for its text-to-image AI system, DALL-E. Outpainting allows the system to imagine what's outside the frame of famous works such as Girl with The Pearl Earring, Mona Lisa and Dogs Playing Poker. DALL-E relies on artificial neural networks (ANNs), which simulate the way the brain works in order to learn and create an image from text. Now with Outpainting, users must describe the extended visuals in text form for DALL-E to “paint” the newly imagined artwork. Outpainting, which is primarily aimed for professionals who work with images, will let users 'extend their creativity' and 'tell a bigger story', according to OpenAI. US artist August Kamp used Outpainting to reimagine the famous 1665 painting Girl with a Pearl Earring by Johannes Vermeer, extending the background in the original style. The results show the iconic subject in a domestic setting, surrounded by crockery, houseplants, fruit, boxes and more. Other Outpainting attempts took a more creative turn, with one showing the Mona Lisa surrounded by a dystopian wasteland, and a version of A Friend In Need showing an additional table of gambling canines. <blockquote class="twitter-tweet"> “Outpainting: an apocalyptic Mona Lisa” by tonidl1989<a href="https://twitter.com/hashtag/dalle?src=hash&ref_src=twsrc%5Etfw">#dalle</a> <a href="https://twitter.com/hashtag/dalle2?src=hash&ref_src=twsrc%5Etfw">#dalle2</a> <a href="https://twitter.com/hashtag/aiart?src=hash&ref_src=twsrc%5Etfw">#aiart</a> <a href="https://twitter.com/hashtag/aiartwork?src=hash&ref_src=twsrc%5Etfw">#aiartwork</a> <a href="https://t.co/puYVxjyFMm">pic.twitter.com/puYVxjyFMm</a> — Best Dalle2 AI Art 🎨 (@Dalle2AI) <a href="https://twitter.com/Dalle2AI/status/1565168579376566278?ref_src=twsrc%5Etfw">September 1, 2022</a></blockquote> <blockquote class="twitter-tweet"> Used DALL-E 2’s new “outpainting” feature to expand the world’s greatest work of art… <a href="https://t.co/0HXQzngt9P">pic.twitter.com/0HXQzngt9P</a> — M.G.

Anne Heche's blood test results revealed after horror smash

An investigation of Anne Heche’s blood results have detected “the presence of drugs” following <a href="https://www.oversixty.com.au/news/news/new-details-of-actor-anne-heche-s-fiery-crash" target="_blank" rel="noopener">her horror smash</a>. The US actress was pulled out of her burning car after she smashed into a mansion in Los Angeles while driving a terrifying 140km/h on August 5. The 53-year-old suffered severe injuries and soon after the crash fell into a coma and has not regained consciousness since. Almost a week after the incident, a Los Angeles Police Department Public Information Officer confirmed there was a “presence of drugs” in Anne’s blood system. “Based on the blood draw, it revealed the presence of drugs, however additional testing is required to rule out any substances that were administered at the hospital as part of her medical treatment,” they told <a href="https://www.foxnews.com/entertainment/anne-heche-blood-test-revealed-presence-of-drugs" target="_blank" rel="noopener">Fox News Digital</a>. "Any secondary drugs [takes] up to 30 days for [a] secondary test to come back.” TMZ previously reported that Anne had cocaine in her system upon arrival at the hospital, but that is yet to be confirmed. The crash is currently being investigated by the LAPD who have confirmed that if Anne is found to have been drunk she would face significant charges. "If found intoxicated, [Heche] could be charged with misdemeanour DUI hit and run. No arrests have been made so far,” a representative said. Anne’s representative has confirmed that she is in an “extreme critical condition”. “She has a significant pulmonary injury requiring mechanical ventilation and burns that require surgical intervention,” her representative said. “She is in a coma and has not regained consciousness since shortly after the accident.” Image: Getty

Pay ‘with a smile or a wave’: Why Mastercard’s new face recognition payment system raises concerns

Mastercard’s <a href="https://www.mastercard.com/news/press/2022/may/with-a-smile-or-a-wave-paying-in-store-just-got-personal/" target="_blank" rel="noopener">“smile to pay”</a> system, announced last week, is supposed to save time for customers at checkouts. It is being trialled in Brazil, with future pilots planned for the Middle East and Asia. The company argues touch-less technology will help speed up transaction times, shorten lines in shops, heighten security and improve hygiene in businesses. But it raises concerns relating to customer privacy, data storage, crime risk and bias. How will it work? Mastercard’s biometric checkout system will provide customers facial recognition-based payments, by linking the biometric authentication systems of a number of third-party companies with Mastercard’s own payment systems. A Mastercard spokesperson told The Conversation it had already partnered with NEC, Payface, Aurus, Fujitsu Limited, PopID and PayByFace, with more providers to be named. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/464953/original/file-20220524-22-ga0v7l.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/464953/original/file-20220524-22-ga0v7l.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/464953/original/file-20220524-22-ga0v7l.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=400&fit=crop&dpr=1 600w, https://images.theconversation.com/files/464953/original/file-20220524-22-ga0v7l.jpeg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=400&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/464953/original/file-20220524-22-ga0v7l.jpeg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=400&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/464953/original/file-20220524-22-ga0v7l.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=503&fit=crop&dpr=1 754w, https://images.theconversation.com/files/464953/original/file-20220524-22-ga0v7l.jpeg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=503&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/464953/original/file-20220524-22-ga0v7l.jpeg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=503&fit=crop&dpr=3 2262w" alt="The 'Fujitsu' logo in red is displayed on a building's side" /></a><figcaption>Mastercard has partnered with Fujitsu, a massive information and communications technology firm offering many different products and services. Shutterstock</figcaption></figure> They said “providers need to go through independent laboratory certification against the program criteria to be considered” – but details of these criteria aren’t yet publicly available. According to <a href="https://www.siliconrepublic.com/business/mastercard-facial-recognition-biometric-payments" target="_blank" rel="noopener">media</a> reports, customers will have to install an app which will take their picture and payment information. This information will be saved and stored on the third-party provider’s servers. At the checkout, the customer’s face will be matched with the stored data. And once their identity is verified, funds will be deducted automatically. The “wave” option is a bit of a trick: as the customer watches the camera while waving, the camera still scans their face – not their hand. Similar authentication technologies are used on smartphones (face ID) and in many airports around the world, including “<a href="https://www.abf.gov.au/entering-and-leaving-australia/smartgates/arrivals" target="_blank" rel="noopener">smartgates</a>” in Australia. <a href="https://www.theverge.com/2017/9/4/16251304/kfc-china-alipay-ant-financial-smile-to-pay" target="_blank" rel="noopener">China</a> started using biometrics-based checkout technology back in 2017. But Mastercard is among the first to launch such a system in Western markets – competing with the “pay with your palm” <a href="https://techcrunch.com/2020/09/29/amazon-introduces-the-amazon-one-a-way-to-pay-with-your-palm-when-entering-stores/" target="_blank" rel="noopener">system</a> used at cashier-less Amazon Go and Whole Foods brick and mortars in the United States. What we don’t know Much about the precise functioning of Mastercard’s system isn’t clear. How accurate will the facial recognition be? Who will have access to the databases of biometric data? A Mastercard spokesperson told The Conversation customers’ data would be stored with the relevant biometric service provider in encrypted form, and removed when the customer “indicates they want to end their enrolment”. But how will the removal of data be enforced if Mastercard itself can’t access it? Obviously, privacy protection is a major concern, especially when there are many potential third-party providers involved. On the bright side, Mastercard’s <a href="https://www.investopedia.com/articles/markets/032615/how-mastercard-makes-its-money-ma.asp" target="_blank" rel="noopener">customers</a> will have a choice as to whether or not they use the biometrics checkout system. However, it will be at retailers’ discretion whether they offer it, or whether they offer it exclusively as the only payment option. Similar face-recognition technologies used in airports, and <a href="https://www.brookings.edu/research/police-surveillance-and-facial-recognition-why-data-privacy-is-an-imperative-for-communities-of-color/" target="_blank" rel="noopener">by police</a>, often offer no choice. We can assume Mastercard and the biometrics provider with whom they partner will require customer consent, as per most privacy laws. But will customers know what they are consenting to? Ultimately, the biometric service providers Mastercard teams up with will decide how they use the data, for how long, where they store it, and who can access it. Mastercard will merely decide what providers are “good enough” to be accepted as partners, and the minimum standards they must adhere to. Customers who want the convenience of this checkout service will have to consent to all the related data and privacy terms. And as reports have noted, there is potential for Mastercard to integrate the feature with loyalty schemes and make personalised recommendations <a href="https://www.cnbc.com/2022/05/17/mastercard-launches-tech-that-lets-you-pay-with-your-face-or-hand.html" target="_blank" rel="noopener">based on purchases</a>. Accuracy is a problem While the accuracy of face recognition technologies has previously been challenged, the current best facial authentication algorithms have an error of just 0.08%, according to tests by the <a href="https://github.com/usnistgov/frvt/blob/nist-pages/reports/1N/frvt_1N_report_2020_03_27.pdf" target="_blank" rel="noopener">National Institute of Standards and Technology</a>. In some countries, even banks have <a href="https://techhq.com/2020/09/biometrics-the-most-secure-solution-for-banking/" target="_blank" rel="noopener">become comfortable</a> relying on it to log users into their accounts. Yet we can’t know how accurate the technologies used in Mastercard’s biometric checkout system will be. The algorithms underpinning a technology can work almost perfectly when trailed in a lab, but perform <a href="https://www.csis.org/blogs/technology-policy-blog/how-accurate-are-facial-recognition-systems-%E2%80%93-and-why-does-it-matter" target="_blank" rel="noopener">poorly</a> in real life settings, where lighting, angles and other parameters are varied. Bias is another problem In a 2019 study, NIST <a href="https://nvlpubs.nist.gov/nistpubs/ir/2019/NIST.IR.8280.pdf#page=5" target="_blank" rel="noopener">found</a> that out of 189 facial recognition algorithms, the majority were biased. Specifically, they were less accurate on people from racial and ethnic minorities. Even if the technology has improved in the past few years, it’s not foolproof. And we don’t know the extent to which Mastercard’s system has overcome this challenge. If the software fails to recognise a customer at the check out, they might end up disappointed, or even become irate – which would completely undo any promise of speed or convenience. But if the technology misidentifies a person (for instance, John is recognised as Peter – or <a href="https://www.youtube.com/watch?v=e8-yupM-6Oc" target="_blank" rel="noopener">twins are confused</a> for each other), then money could be taken from the wrong person’s account. How would such a situation be dealt with? <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/464424/original/file-20220520-19-5hfuvx.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/464424/original/file-20220520-19-5hfuvx.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/464424/original/file-20220520-19-5hfuvx.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=617&fit=crop&dpr=1 600w, https://images.theconversation.com/files/464424/original/file-20220520-19-5hfuvx.jpeg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=617&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/464424/original/file-20220520-19-5hfuvx.jpeg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=617&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/464424/original/file-20220520-19-5hfuvx.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=776&fit=crop&dpr=1 754w, https://images.theconversation.com/files/464424/original/file-20220520-19-5hfuvx.jpeg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=776&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/464424/original/file-20220520-19-5hfuvx.jpeg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=776&fit=crop&dpr=3 2262w" alt="" /></a><figcaption>There’s no evidence facial recognition technology is infallible.

In the wrong hands, this data could lead to <a href="https://www.comparitech.com/identity-theft-protection/identity-theft-statistics/" target="_blank" rel="noopener">identity theft</a>, which is one of the fastest growing types of crime, and financial fraud. Do we want it? Mastercard suggests 74% of customers are in favour of using such technology, referencing a stat from its <a href="https://www.mastercard.com/news/ap/en/newsroom/press-releases/en/2020/april/mastercard-study-shows-consumers-moving-to-contactless-payments-for-everyday-purchases/" target="_blank" rel="noopener">own study</a> – also used by <a href="https://www.mastercard.com/news/ap/en/newsroom/press-releases/en/2020/october/mastercard-idemia-and-matchmove-pilot-fingerprint-biometric-card-in-asia-to-enhance-security-and-safety-of-contactless-payments" target="_blank" rel="noopener">business partner</a> Idemia (a company that sells biometric identification products). But the report cited is vague and brief. Other studies show entirely different results.

”Fix the system not me”: A first for Australian Fashion Week

In a first for the yearly week-long display of new Aussie fashion, adaptive clothing has taken the fore through a show solely focused on the underrepresented sphere of fashion. Day four of <a href="https://aafw.com.au/index" target="_blank" rel="noopener">Australian Fashion Week</a> saw a collective of designers take to the runway with fashionable garments that can be worn by both abled and disabled people and were modelled by the very people who inspired them. JAM and Christine Stephens, two designers whose designs were featured, share a mutual goal: to act as a voice for the adaptive designers collective and highlight the possibilities for stylish fashion that is inclusive. <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-captioned="" data-instgrm-permalink="https://www.instagram.com/p/CdcVj66rDK8/?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/p/CdcVj66rDK8/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Australian Fashion Week (@ausfashionweek)</a> </div> </blockquote> “We want to give people living with disabilities a choice. A choice in fashion, a choice to be included and a choice to be heard,” Jessie Sadler and Carol Taylor, two designers for Christine Stephens, said in a press release. Taylor, the co-owner and lead designer of the fashion label, said the collection was inspired by a quadriplegic groom-to-be who “would never know what it would be like to unwrap his able-bodied bride”. <img src="https://oversixtydev.blob.core.windows.net/media/2022/05/fashion-week1.jpg" alt="" width="1280" height="720" /> Models with disabilities took to the runway for the Adaptive Clothing Collective show. Image: Getty Images The outfits included multiple adaptive features, such as particularly magnetic button closures and zips to improve access for prosthetic users and even particularly contrasting colour choices. One model’s outfit, a sky-blue two-piece suit with contrasting magenta collars and inner linings, was inspired by their visual impairment that prevents them from distinguishing between darker colours, as reported by <a href="https://www.elle.com.au/fashion/adaptive-clothing-collective-australian-fashion-week-2022-27051" target="_blank" rel="noopener">Elle Australia</a>. The runway featured disabled models throughout the show, including actress Chloé Hayden, who told <a href="https://www.refinery29.com/en-au/2022/05/10974587/adaptive-fashion-runway" target="_blank" rel="noopener">Refinery29</a> being asked to participate was an “out of this world” experience. “I grew up practising my model walk, doing personal little photo shoots, going to those Dolly model searches … I’m always jaw dropping at Australian Fashion Week,” she told the publication. <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-captioned="" data-instgrm-permalink="https://www.instagram.com/p/CdcszIUBLKa/?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/p/CdcszIUBLKa/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Chloé Hayden (@chloeshayden)</a> </div> </blockquote> Following her appearance in the show, where she wore olive utility-style boots and a trench coat with the slogan ‘Fix the system, not me’, Hayden took to Instagram to share clips and her excitement. “Australian Fashion Week’s first adaptive runway. Let it not be the last,” she captioned the post. “More posts to come once I stop projectile crying and stimming.” Lisa Cox, an author, consultant and disability influencer who modelled for Christina Stephens, said the opportunity made her feel “seen” by the industry. “I feel more accepted and I feel seen by an industry that I haven’t felt a part of since I became disabled over 16 years ago … I feel both honoured and privileged to be part of such a landmark event in Australian fashion history,” she told Refinery29. Cox added that the absence of inclusivity in fashion has left her feeling unimportant and uncatered for - which she noted was also bad for those in the clothing business. “[It’s] offensive and it really hurts,” she said. “But on the other hand, people with disabilities are consumers too so that attitude is just bad business. My legs don’t work but my credit card does!” Emma Clegg and Molly Rogers, the creators of JAM the label, said the “universal design” of adaptive clothing is more comfortable, convenient and accessible for everyone, and encourage non-disabled people to also give them a try. "Purchasing from and supporting Australian inclusive [and] adaptive fashion brands will prove to the Australian fashion industry that there is the demand out there, and they need to be including people with disability throughout their businesses,” they told Refinery29. “It shouldn't be newsworthy that there is a designer with disabilities or clothes for people with disabilities at AAFW, but for now it must be celebrated,” Cox said. Whether you approach the issue from a position of fairness or business, with 20 percent of Australians living with a disability, it makes sense to design clothing that can be worn and enjoyed by everyone - and hopefully this show is just the first of many more. Here's a look at the styles appearing at the show. Image: Getty Images

"Australian GeoGRAPHIC!": Hilarious echidna pic breaks the internet

A hilarious yet graphic photo of an echidna’s penis has shocked the internet after randomly popping up in their news feed. The photo was uploaded by Australian Geographic asking readers if they had ever seen an echidna’s penis before. The photo in question shows a four-tipped penis with scientists looking into why the mammal’s reproductive system is the way it is. “Have you ever seen an echidna’s penis?” the post read. “You’ve probably asked your friends this in jest, but scientists are working away at unlocking the mystery of the bizarre, four-tipped reproductive system. “Labelled one of the ‘weirdest penises of the animal kingdom’, it's bright red and has four heads. “Now there's a dinner conversation starter…” The internet’s reaction was lighthearted, with many in the comment section leaving funny remarks. <iframe style="overflow: hidden; border: initial none initial;" src="https://www.facebook.com/plugins/post.php?href=https%3A%2F%2Fwww.facebook.com%2Fausgeo%2Fposts%2F10158869200833339&show_text=true&width=500" width="500" height="780" frameborder="0" scrolling="no" allowfullscreen="allowfullscreen"></iframe> “Such prickly little buggers obviously they need all the help they can get,” someone joked. “Australian GeoGRAPHIC,” the best comment read. “I'm guessing it's for Russian roulette impregnation,” another commented. “I cannot unsee this. Scarred for life,” someone else joked. “Wears condoms. They fit like a glove,” another comment read. “If I were a female echidna, I’d shuffle away as fast as I could from this thing and if I couldn’t out shuffle it, I’d bury myself as quickly as possible,” someone wrote. Despite the funny comments, Australian Geographic linked back to a <a href="https://www.australiangeographic.com.au/topics/wildlife/2021/05/echidna-penises-why-theyre-so-weird/?fbclid=IwAR3kQEzjVHQDodmTLm7FbqgH7ixIxcm8V0UFNzIHx9xgXofvsqkJaCc2tHI" target="_blank" rel="noopener">research article</a> about why echidna penises are weird. ”We’re not really sure why it looks so weird but we do know that they only use their penis for mating, not urine,” reproductive biologist Jane Fenelon said. “Because they don’t need it for urine, they had the freedom to make it much more elaborate and this is something you see in other species that only use it for mating.” Images: Australian Geographic

Grandma's hilarious ranking system goes viral

Many suspect their grandma may have favourites, but one family knows for sure where they stand thanks to their grandmother’s brutally honest "leaderboard". US comedian Dan LaMorte posted on TikTok explaining the unique feature in his grandmother's house, where at any time family members can look to see how beloved they are in their matriarch's eyes – and heart. "At my grandma’s house she has a board of the ten grandchildren's faces on magnets, and she ranks us from one to ten. I'm eight," he says proudly before cutting the video off. The comedian's TikTok followers found the system hilariously honest. "I would kill for this kind of transparency in my relationships," said one commenter. "I would have told her that she my #2 grandma," added another. "My grandma used to rank us too. She would regularly tell us of our rankings. She's been gone for 4 years, but I talk about her a lot in therapy," said one commenter. "That was the basis behind this. She used to do verbal rankings so we made her a board to do it visually," revealed LaMorte. In a separate video, the comedian displays the rankings again three months on, explaining some of the reasoning behind the shifts in order. He reveals that the number one favourite grandchild lives next door so she moves her ranking herself and is therefore invalid, while number two is a dentist and number three is a doctor. He also adds that he moved up two places, now at sixth place out of the ten grandchildren. "The key is to coast and wait for the others to mess up. The long game," one commenter suggested. "My great-grandmother's favorite grandchild is my childhood dog, whose portrait takes center stage in her home," said another. Image: TikTok

Meditation could boost your immune system

A <a rel="noopener" href="https://www.scimex.org/newsfeed/how-meditation-could-help-boost-the-immune-system" target="_blank">new study</a> has connected intensive meditation with altered behaviour of over 200 genes tied to immunity, with their findings suggesting that meditation may be beneficial for those with a weakened immune system. The research, recently published in the journal <a rel="noopener" href="https://www.pnas.org/content/118/51/e2110455118" target="_blank">Proceedings of the National Academy of Sciences (PNAS)</a>, involved analysing blood samples from 106 volunteers who participated in an intensive Samyama meditation retreat. The participants spent eight days in complete silence, followed a strict vegan diet and regular sleep schedule, and meditated for more than ten hours each day. Several samples were taken from each participant, including one two months before the retreat, another five weeks before, two immediately before and after the retreat, and a final sample three months after it ended. After analysing the gene expression in the samples, the team found that there were “distinct” alterations in how genes were expressed after participants meditated. In particular, they found that 220 genes tied to immunity had higher levels of expression without an increase in inflammation. Sixty-eight of these genes were also tied to signalling proteins called interferons. These proteins help our immune systems to identify viruses and trigger immune cells to fight viral cells, stopping them from multiplying. “These findings suggest that meditation has an immediate impact on immune cells and genes,” the authors wrote. They also discovered that there wasn’t an increase in inflammation Though many studies have found that meditation has a positive impact on our health, this new research investigates what happens inside human cells when we meditate to explain why we experience these positive effects. By examining the gene expression before and after meditation, the authors suggest that meditation could be helpful for treating conditions characterised by a weakened immunity and persistent inflammation. “Together, these results make meditation an effective behavioural intervention for treating various conditions associated with a weakened immune system,” they concluded.

Can mental healthcare be automated?

Depression is predicted to become the <a rel="noreferrer noopener" href="https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.0030442" target="_blank">leading global cause of loss of life years</a> due to illness by 2030, yet <a rel="noreferrer noopener" href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5288082/" target="_blank">fewer than one in five people</a> who suffer depression receive appropriate care. And there are <a rel="noreferrer noopener" href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(21)02143-7/fulltext" target="_blank">worrisome signs</a> the COVID-19 pandemic is exacerbating triggers of the disease. As the burden of disease rises around the world, mental healthcare systems, <a rel="noreferrer noopener" href="https://www.who.int/news/item/08-10-2021-who-report-highlights-global-shortfall-in-investment-in-mental-health" target="_blank">many of which are already patently inadequate</a>, will be stretched thin. That’s why many experts are turning to digital interventions to help manage surging demand, packaging up psychotherapeutic treatments into computer programs and apps that can be used at home. But how effective are digital interventions? And will people accept therapy without a human face? These are the questions an international team of researchers from Finland, Germany, the Netherlands and Italy sought to answer through a systematic review and meta-analysis <a rel="noreferrer noopener" href="https://doi.org/10.1037/bul0000334" target="_blank">published today</a> in Psychological Bulletin. The team analysed 83 studies published between 1990 and 2020, reporting on 15,530 individuals, making it the largest and most comprehensive analysis of digital mental healthcare to date. The findings, while mixed, are promising. Software alone not enough The data suggests that digital interventions are effective in the treatment of depression, but the best results come when a digital program is augmented by support from an actual human. That’s when digital therapy can actually rival the effectiveness of face-to-face therapy. “Digital interventions could provide a viable, evidence-based method of meeting the growing demand for mental healthcare, especially where people are unable to access face-to-face therapy due to long waiting lists, financial constraints or other barriers,” says Isaac Moshe, lead author of the study and a PhD researcher at the University of Helsinki. But, he notes, “software alone just isn’t enough for many people, especially individuals who suffer from moderate or more severe symptoms.” Interestingly, the researchers found that while a level of human support behind a digital program was important, there was no marked difference in outcomes whether that support was provided by a highly experienced clinician or someone with less experience, such as a student or trainee. Moshe says that means digital programs could be scaled up by relying on less experienced practitioners, and offer a powerful solution to a growing problem. Even with the assistance of a clinician, however, there are barriers to the uptake of digital healthcare. According to <a rel="noreferrer noopener" href="https://www.pharmaceutical-technology.com/news/cost-security-concerns-and-lack-of-integration-into-existing-workflow-the-main-barriers-to-the-adoption-of-digital-health-tools-poll/" target="_blank">one industry-based poll</a>, major barriers include cost, security concerns and a lack of digital savviness among patients. Another major therapeutic concern is the idea that spending time working face-to-face with a human builds trust and a sense of alliance. This is <a rel="noreferrer noopener" href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7016304/" target="_blank">particularly true</a> among older generations. Digital healthcare is also generally only appropriate for those who can afford the means to access it through a mobile phone or computer. That means it’s inaccessible for many people living in poverty or in remote communities. AI has a role to play The researchers also say artificial intelligence may have a role to play, principally in flagging risk factors for mental health, as well as helping clinicians develop tailor-made interventions. “Over three billion people now own a smartphone and wearable devices are growing in popularity,” explains Lasse Sander from the University of Freiburg, who led the research team. “These devices produce a continuous stream of data related to a person’s behaviour and physiology. With new developments in artificial intelligence and machine learning, we now have promising methods of using this data to identify if someone is at risk of developing a mental illness.” Moshe cautions that the results are focused on moderate depression, and that digital interventions may not be sufficient to cater to severe cases. “There are very few studies involving people with severe depression or individuals at risk of suicide, leaving the evidence unclear for the role of digital interventions for the treatment of severe and complex depression,” he says.  <img id="cosmos-post-tracker" style="opacity: 0; height: 1px!important; width: 1px!important; border: 0!important; position: absolute!important; z-index: -1!important;" src="https://syndication.cosmosmagazine.com/?id=176089&title=Can+mental+healthcare+be+automated%3F" alt="" width="1" height="1" />  <div id="contributors"> <a rel="noopener" href="https://cosmosmagazine.com/health/body-and-mind/can-digital-mental-healthcare-be-automated/" target="_blank">This article</a> was originally published on <a rel="noopener" href="https://cosmosmagazine.com" target="_blank">Cosmos Magazine</a> and was written by <a rel="noopener" href="https://cosmosmagazine.com/contributor/amalyah-hart" target="_blank">Amalyah Hart</a>.

Older Australians are already bamboozled by a complex home-care system. So why give them more of the same?

More than <a href="https://www.aihw.gov.au/reports/australias-welfare/aged-care">a million older Australians</a> need care at home each year. <a href="https://www.health.gov.au/sites/default/files/documents/2021/08/ninth-report-on-the-funding-and-financing-of-the-aged-care-industry-july-2021.pdf">More than 1,000 agencies</a> provide services to them. Despite the federal government allocating <a href="https://www.health.gov.au/initiatives-and-programs/aged-care-reforms/a-generational-plan-for-aged-care">significant extra funds to home care</a> in the last budget, there is still a raft of problems with current home-care arrangements. As we show in <a href="https://grattan.edu.au/report/unfinished-business-practical-policies-for-better-care-at-home/">our new report</a>, “Unfinished business: practical policies for better care at home”, the federal government is placing too much emphasis on expanding the market of services, and not enough on supporting people to access timely and quality services. Home care support ranges from help with personal care and cleaning the house, to provision of mobility aids, and transport to social events and medical appointments. People who need care at home can explore options via the federal government’s <a href="https://www.myagedcare.gov.au/">myagedcare</a> website. Then they can get assessed, find a local provider to suit their needs, and manage their own care. But this system is <a href="https://www.ingentaconnect.com/contentone/tpp/ijcc/2020/00000004/00000003/art00006">impersonal and cumbersome</a>. Assessment of people’s needs is divorced from planning their services. Older people get little advice and support to find services, and people who need more intensive and complex care often have to wait for more than a year. Administrative and coordination costs for the <a href="https://www.aihw.gov.au/reports/australias-welfare/aged-care">200,000 people who get home care packages</a> are high, hourly service charges are unregulated, and there is more than <a href="https://www.stewartbrown.com.au/images/documents/StewartBrown_-_ACFPS_Financial_Performance_Sector_Report_June_2021.pdf">A$1.6 billion in unspent funds</a> that could be used to provide services. The number of private services has grown dramatically, with little oversight of quality and value for money. At the same time, home-care workers <a href="https://www.smh.com.au/politics/federal/canberra-told-to-pay-up-to-get-aged-care-workers-a-25-per-cent-rise-20210705-p586x9.html">remain poorly paid and under-valued</a>. Training is patchy, work is often insecure, and there’s insufficient supervision, support and staff development. Not surprisingly, it is increasingly difficult to recruit and retain aged-care workers. <h2>What’s wrong with the extra funding?</h2> The federal government’s response to the landmark <a href="https://agedcare.royalcommission.gov.au/">Royal Commission into Aged Care</a> was substantial, but it doesn’t change the fundamentals of the home-care system. It expands a market that is not working for older people. The government is putting its faith in a centrally regulated market model, dominated by private and non-government home-care businesses. Even with the massively increased home-care funding, the market may still not provide enough to reduce waiting times for services to less than a month, as the royal commission recommended. <a href="https://images.theconversation.com/files/436568/original/file-20211209-137612-sxaiia.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/436568/original/file-20211209-137612-sxaiia.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="Elderly lady using laptop at home" /></a> Older people will still have to navigate a complex system and make market choices largely on their own. <a href="https://www.shutterstock.com/image-photo/asian-old-woman-using-computer-69690976" class="source">Shutterstock</a> There are currently almost <a href="https://gen-agedcaredata.gov.au/www_aihwgen/media/Home_care_report/Home-Care-Data-Report-1st-Qtr-2021-22.pdf">75,000 waiting for the home care support they need</a>, with some having waited up to nine months. We calculate that up to 15% more home-care places than planned could be needed just to clear the waiting list. We call on the federal government to keep waiting times to 30 days or less. The government’s budget package does include additional support to help older people navigate their way through the home-care system. But assessment, care finding, and care coordination will continue to be fragmented. In the main, older people will still have to navigate a complex system and make market choices on their own. <h2>We need to go local to provide the best support</h2> Australia needs a new home care model – one that provides much more personalised support to help older people get the services they need and that manages local service systems on their behalf. It’s difficult to see this being done without establishing effective regional aged-care offices. These offices need to provide a one-stop shop for older people. Yet they also need to have the authority and responsibility to develop and manage local services to make sure older people can get what they need. The federal government is aware of this problem, but its response is tepid – <a href="https://www.health.gov.au/sites/default/files/documents/2021/05/governance-pillar-5-of-the-royal-commission-response-strengthening-regional-stewardship-of-aged-care.pdf">a trial</a> of small, regional offices of up to ten people to plan, monitor and solve problems. But those regional offices have no responsibility for supporting older people, and no authority to manage service providers on their behalf. We recommend the federal government establish a network of regional aged-care offices across Australia to plan and develop services, hold funds, pay providers, and administer service agreements for individual older people who need care. These offices should include assessment teams and care finders, to help people who are trying to navigate the home-care system. Good quality home care depends on a well-qualified, secure and valued workforce. Again, the federal government is aware of this problem and has introduced a limited set of workforce reforms. But it has not yet agreed to support improved pay and conditions, minimum qualification standards or a full registration scheme for personal-care workers. The government should develop and implement a revitalised workforce plan for aged care as part of the <a href="https://www.health.gov.au/initiatives-and-programs/aged-care-reforms/aged-care-legislative-reform">new Aged Care Act</a>. Personal-care workers should be registered and hold suitable minimum qualifications. The government should also make it clear it will fund the outcomes of the <a href="https://www.fwc.gov.au/cases-decisions-orders/major-cases/work-value-case-aged-care-industry">Fair Work Commission</a> review of fair pay and conditions for aged-care workers, with a ruling expected next year. As Australia’s population continues to age, many more people with complex needs will need care. The vast majority of them will prefer to be supported at home. Massively expanding home-care services without much stronger market management, and a much more secure workforce, is a risk Australia shouldn’t take.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important; text-shadow: none !important;" src="https://counter.theconversation.com/content/173326/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/stephen-duckett-10730">Stephen Duckett</a>, Director, Health and Aged Care Program, <a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a> and <a href="https://theconversation.com/profiles/hal-swerissen-9722">Hal Swerissen</a>, Emeritus Professor, La Trobe University, and Fellow, Health Program, <a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Overhaul of payments system to cover digital wallets, buy now pay later, cryptocurrency

Treasurer Josh Frydenberg will announce on Wednesday a comprehensive reform of regulations governing the payments system, to bring it up to date with innovations such as digital wallets and cryptocurrency. The government says without the changes – the biggest in 25 years – Australians businesses and consumers could increasingly be making transactions in spaces beyond the full reach of Australian law, where rules were determined by foreign governments and multinationals. It points out that in three decades payment methods have gone from cash to cheques, cheques to credit cards, credit cards to debit cards and now to “tap and go” via digital wallets on phones or watches. Around a decade ago, cryptocurrency was a concept. Currently, there are more than 220 million participants in the worldwide crypto market, including many in Australia. The planned reforms will centralise oversight of the payment system by ensuring government plays a greater leadership role. The treasurer will be given more power to intervene in certain circumstances. Consumer protection will be strengthened, and more competition and innovation will be promoted. The reform program will be in two phases. There will be consultations in the first half of next year on those that are most urgent and easy to implement. Consultations on the rest will be done by the end of the year. The government says the present one-size-fits-all licensing framework for payment service providers will be replaced graduated, risk-based regulatory requirements. There will be consideration of the feasibility of a retail central bank digital currency, and an examination of “de-banking” (where a bank declines to offer a service to a business or individual). Frydenberg says the comprehensive payments and crypto asset reform program would “firmly place Australia among a handful of lead countries in the world. "It is how we will capitalise on the opportunity for Australia to lead the world in this emerging and fast-growing area which has almost endless potential applications across the economy,” he says. “For businesses, these reforms will address the ambiguity that can exist about the regulatory and tax treatment of crypto assets and new payment methods. "In doing so, it will drive even more consumer interest, facilitate even more new entrants and enable even more innovation to take place. "For consumers, these changes will establish a regulatory framework to underpin their growing use of crypto assets and clarify the treatment of new payment methods.”<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important; text-shadow: none !important;" src="https://counter.theconversation.com/content/173331/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/michelle-grattan-20316">Michelle Grattan</a>, Professorial Fellow, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

AI-system promises better art reproductions – but not yet

<div> <div class="copy"> A team from the Computer Science and Artificial Intelligence Laboratory at the Massachusetts Institute of Technology in the US is developing a new, deep learning-assisted system to reproduce art with a 3D printer to make more accurate, convincing reproductions. The system combines a process known as halftoning, which uses little dots of ink, and a layering technique that has 10 different colours, rather than the usual cyan, magenta, yellow, and black of 2D printers. This keeps the ink from blotting, which happens when too much is deposited on the printing surface, and it allows the printer to produce a wider range of tones. The technique, combined with a “deep learning model to predict the optimal stack of different inks”, results in “unprecedented spectral accuracy”, the team writes in a new paper, being presented this month at a <a rel="noopener" href="https://sa2018.siggraph.org/en/" target="_blank">computer graphics conference in Tokyo</a>. “If you just reproduce the colour of a painting as it looks in the gallery, it might look different in your home,” says Changil Kim, one of the paper’s authors. “Our system works under any lighting condition, which shows a far greater colour reproduction capability than almost any other previous work.”{%recommended 6743%} The researchers they hope the project will eventually make art more available, since “our reliance on museums to exhibit original paintings and sculpture inherently limits access and leaves those precious originals vulnerable to deterioration and damage”. “The value of fine art has rapidly increased in recent years, so there’s an increased tendency for it to be locked up in warehouses away from the public eye,” notes mechanical engineer Mike Foshey. “We’re building the technology to reverse this trend, and to create inexpensive and accurate reproductions that can be enjoyed by all.” The developers concede that there is still work to be done on the system, which they named RePaint, to truly render a van Gogh simulacrum. For starters, images like Starry Night use a cobalt blue that the ink library isn’t able to “faithfully reproduce”. But paintings – particularly oil paintings – are three-dimensional works. The brush strokes leave ridges and bumps that can reflect light, throwing off the rendering. Right now, the printer reads glossy reflections as white highlights, but the team has plans to incorporate recognition of “the rich spatially-varying gloss and translucency found in many paintings”. The system will learn to use surface reflection, rather than less colour, to reproduce the gloss. One other issue? Those glorious Monet water lilies look more like postage stamps, since the system’s reproductions are only a few centimetres across. The engineers are hoping to bring down the costs and time printing to accommodate larger reproductions.

5 life lessons from your immune system

Scientists love analogies. We use them continually to communicate our scientific approaches and discoveries. As an immunologist, it strikes me that many of our recurring analogies for a healthy, functioning immune system promote excellent behaviour traits. In this regard, we should all aim to be a little more like the cells of our immune system and emulate these characteristics in our lives and workplaces. Here are five life lessons from your immune system. 1. Build diverse and collaborative teams Our adaptive immune system works in a very specific way to detect and eradicate infections and cancer. To function, it relies on effective team work. At the centre of this immune system team sits dendritic cells. These are the sentinels and leaders of the immune system – akin to coaches, CEOs and directors. They have usually travelled widely and have a lot of “life experience”. For a dendritic cell, this means they have detected a pathogen in the organs of the body. Perhaps they’ve come into contact with influenza virus in the lung, or encountered dengue fever virus in the skin following a mosquito bite. After such an experience, dendritic cells make their way to their local lymph nodes – organs structured to facilitate immune cell collaboration and teamwork. Here, like the best leaders, dendritic cells share their life experiences and provide vision and direction for their team (multiple other cell types). This gets the immune cell team activated and working together towards a shared goal – the eradication of the pathogen in question. The most important aspect of the dendritic cell strategy is knowing <a href="https://www.pnas.org/content/101/46/16385">the strength of combined diverse expertise</a>. It is essential that immune team members come from diverse backgrounds to get the best results. To do this, dendritic cells secrete small molecules known as chemokines. Chemokines facilitate good conversations between different types of immune cells, helping dendritic cells discuss their plans with the team. In immunology, we call this “recruitment”. Much <a href="https://www.nature.com/articles/s41467-018-07634-8">like our workplaces</a>, diversity is key here. It’s fair to say, if dendritic cells only recruited more dendritic cells, our immune system would completely fail its job. Dendritic cells instead hire T cells (among others) and share the critical knowledge and strategy to steer effective action of immune cells. T cells can then pass these plans down the line – either preparing themselves to act directly on the pathogen, or working alongside other cell types, such as B cells that make protective antibodies. In this way, dendritic cells establish a rich and diverse team that works together to clear infections or cancer. 2. Learn through positive and negative feedback Immune cells are excellent students. During development, T cells mature in a way that depends on both positive and negative feedback. This occurs in the thymus, an organ found in the front of your chest and whose function was first discovered by Australian scientist <a href="https://www.wehi.edu.au/about-history/notable-scientists/professor-jacques-miller">Jacques Miller</a> (awarded the <a href="http://www.japanprize.jp/en/prize_prof_2018_miller.html">2018 Japan Prize</a> for his discoveries). As they mature, T cells are exposed to a process of trial and error, and take on board criticism and advice in equal measure, to ensure they are “trained” to respond appropriately to what they “see” (for example, molecules from your own body, or from a foreign pathogen) when they leave the thymus. Importantly, this process is balanced, and T cells must receive both positive and negative feedback to mature appropriately – too much of either on its own is not enough. In the diverse team of the immune system, cells can be both the student and the teacher. This occurs during immune responses with intense cross-talk between dendritic cells, T cells and B cells. In this supportive environment, multiple rounds of feedback allow B cells to gain a tighter grip on infections, tailoring antibodies specifically towards each pathogen. The result of this feedback is so powerful, it can divert cells away from acting against your own body, instead converting them into <a href="https://www.ncbi.nlm.nih.gov/pubmed/29650674">active participants of the immune system team</a>. Developing avenues that promote constructive feedback offers potential to correct autoimmune disorders. 3. A unique response for each situation Our immune system knows that context is important – it doesn’t rely on a “one-size–fits-all” approach to resolve all infections. This allows the cells of our immune system to perfectly respond to different types of pathogens: such as viruses, fungi, bacteria and helminths (worms). In these different scenarios, even though the team members contributing to the response are the same (or similar), our immune system displays emotional intelligence and utilises different tools and strategies depending on the different situations, or pathogens, it encounters. Importantly, our immune system needs to carefully control attack responses to get rid of danger. Being too heavy handed leaves us with collateral tissue damage, such as is seen allergy and asthma. Conversely, weak responses lead to immunodeficiencies, chronic infection or cancer. A major research aim for people working in immunology is to learn how to harness balanced and tailored immune responses for therapeutic benefit. 4. Focus on work/life balance When we are overworked and poorly rested, we don’t function at our peak. The same is true for our immune cells. An overworked immune cell is commonly referred to as being “chronically exhausted”. In this state, T cells are no longer effective at attacking tumour or virus-infected cells. They are lethargic and inefficient, much like us when we overdo it. For T cells, this switch to exhaustion helps ensure a balanced response and avoids collateral damage. However, viruses and cancers exploit this weakness in immune responses by deliberately promoting exhaustion. The rapidly advancing field of immunotherapy has tackled this limitation in our immune system head-on to create new cancer therapeutics. These therapies release cells of their exhaustion, refresh them, so they become effective once more. This therapeutic avenue (called “<a href="https://theconversation.com/2018-nobel-prize-in-physiology-or-medicine-a-turning-point-in-the-war-on-cancer-104191">immune checkpoint inhibition</a>”) is like a self-care day spa for your T cells. It revives them, renewing their determination and efficiency. This has revolutionised the way cancer is treated, leading to the award of the <a href="https://www.nobelprize.org/prizes/medicine/2018/press-release/">2018 Nobel prize in Medicine</a> to two of its pioneers, James P. Allison and Tasuku Honjo. 5. Learn from life experiences The cornerstone of our adaptive immune system is the ability to remember our past infections. In doing so, it can respond faster and in a more targeted manner when we encounter the same pathogen multiple times. Quite literally, if it doesn’t kill you, it makes your immune system stronger. Vaccines exploit this modus operandi, providing immune cells with the memories without the risk of infection. Work still remains to identify the pathways that optimise formation of memory cells that drive this response. Researchers aim to discover which memories are the most efficient, and how to make them target particularly recalcitrant infections, such as malaria, HIV-AIDS and seasonal influenza. While life might not have the shortcuts provided by vaccines, certainly taking time to reflect and learn after challenges can allow us to find better, faster solutions to future problems. <a href="https://theconversation.com/profiles/joanna-groom-550055">Joanna Groom</a>, Laboratory Head, <a href="https://theconversation.com/institutions/walter-and-eliza-hall-institute-822">Walter and Eliza Hall Institute</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Juries need to be told how they're allowed to use the internet to ensure fair trials

<a href="https://theconversation.com/profiles/jemma-holt-940717">Jemma Holt</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> and <a href="https://theconversation.com/profiles/brendan-gogarty-146584">Brendan Gogarty</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> Juries are supposed to consider evidence without influence or bias from the outside world. However, the <a href="https://www.consultancy.com.au/news/616/9-out-of-10-australian-citizens-now-own-a-smartphone">widespread access to and use of the internet and social media</a> threatens to undermine this, with significant consequences for our criminal justice system and those within it. Given courts cannot effectively police smart-phone use they must adapt to it. This week the <a href="https://www.utas.edu.au/law-reform">Tasmania Law Reform Institute</a> completed its <a href="https://cdn.theconversation.com/static_files/files/842/Jurors_and_Social_Media_FR_A4_04_secure.pdf?1579503016">year long inquiry</a> into courts and the information age, and has recommendations as to how they can adapt. <div class="embed-responsive embed-responsive-16by9"><iframe class="embed-responsive-item" src="https://www.youtube.com/embed/RxmrZ7y9cwg"></iframe></div> <div class="embed-responsive embed-responsive-16by9">The right to a fair & unbiased trial by your peers</div> An accused person’s right to a fair trial is the most fundamental principle of our criminal justice system. It is a phrase that describes a system that affords an accused person many protections. That system relies on jurors being impartial and returning a verdict that is based solely on the evidence that is presented within the courtroom. In the past this was readily easy to achieve. Juror communications during trial hours and even after them could be controlled. News about the trial was generally a local affair, and even when it attracted national attention, the journalists needed to be in the court’s jurisdiction to report, so they and their employers were subject to the court’s authority. The shift in the way people access news, information and communications in the modern age has changed this reality. Almost every Australian has access to the internet via their smartphone or other devices, social media use is habitual among much of our population, and the internet is a ubiquitous source of information for most people. Jurors are no different – in fact, they represent the wider Australian community these statistics describe. While jurors’ smart phones are removed from them during trial, they cannot be before or after the trial period, nor at the beginning or end of the day. As a result jurors may intentionally, or simply by habit seek out or communicate information about the trial. Use and misuse of social media Between 2018 and 2020 the Tasmanian Law Reform Institute conducted an inquiry into juror misuse of the internet and social media during trials. The institute concluded there is likely to be a high, but unquantifiable and undetectable level of misuse. However, there is evidence across Australian jurisdictions that jurors have used their internet connected devices to: <ul> <li> research legal terms or concepts or other information relevant to the trial. A West Australian juror in a drug-related trial obtained information online about <a href="https://www.watoday.com.au/national/western-australia/calls-to-overhaul-wa-jury-system-after-juror-dismissed-for-facebook-post-20161012-gs0wwa.html">methylamphetamine production</a> </li> <li> research the accused, witnesses, victims, lawyers or the judge. Two South Australian jurors sitting in a blackmail trial against multiple defendants conducted online searches about the accused which disclosed <a href="https://www.abc.net.au/news/2016-06-22/jurors-fined-for-contempt-of-court/7533472">past outlaw motorcycle gang affiliations</a> </li> <li> communicate with people involved in the trial. Multiple New South Wales jurors on a long-running fraud trial <a href="https://www.dailytelegraph.com.au/jury-getting-off-their-facebooks/news-story/26e2549a7d9063ae9dae0e2a27683dce">became Facebook friends</a>, sharing posts such as a digitally altered photo of one of the jurors wearing a judge’s wig </li> <li> publish material about the trial on the internet or social media. A NSW juror sitting in a sexual offending trial posted on Facebook <a href="https://www.smh.com.au/national/nsw/facebook-post-sparks-probe-into-jury-conduct-in-sex-crime-trial-20190414-p51dz4.html">the day before the guilty verdict was returned</a>: “When a dog attacks a child it is put down. Shouldn’t we do the same with sex predators?” This post was accompanied with a photograph that showed images of rooms and implements by which lawful executions are carried out. </li> </ul> Misuse is under-reported. In those few instance where reports are made, fellow jurors, rather than court officers, tend to be the ones who raise the issue. Indeed, it is an important part of their role. While jurors across Australia are currently told not to conduct online research, wilful disobedience is only part of the problem. It can also involve unintentional acts by jurors who believe they are doing the right thing. For instance, jurors accessing online news, entertainment or social media sites can be passively influenced by information relevant to the trial. Jurors often misunderstand their role and conduct independent research in the genuine belief their actions are in the pursuit of “fairness” or discovering the truth. Educate, inform & encourage self-regulation The law reform institute ultimately concluded it is impossible for, and beyond the capacity of courts to completely police juror internet use. It has thus recommended not reforming the law, but rather strengthening and standardising juror education and directions. These recommendations are divided across two stages of jury selection, as part of an overall strategy: <ul> <li> pre-selection: prospective jurors should receive improved training and information about the role of the juror and the risks of internet use </li> <li> post-selection: once a jury has been selected, judges need to explain to jurors what dangers arise from using the internet to access and publish on social media, seeking information about the case, parties, court officers, lawyers, and self-conducted research into legal concepts or sentences. The report has recommended the court adopt minimum standard directions, but also have the flexibility to make specific directions relevant to any particular trial. </li> </ul> The report recommended certain current practices and laws should remain unchanged, including: <ul> <li> removing phones from jurors while they are in court (even though the effect is limited it avoids juror distraction) </li> <li> leaving contempt (punishment) laws in place for those jurors who intentionally ignore court training and directions. That might include monetary fines and, in severe cases, imprisonment. </li> </ul> This process is aimed at encouraging self-regulation among jurors, by educating them how to curtail their internet use and why it’s so important. <a href="https://theconversation.com/profiles/jemma-holt-940717">Jemma Holt</a>, Research Fellow/ Acting Executive Officer (Research), Tasmania Law Reform Institute, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> and <a href="https://theconversation.com/profiles/brendan-gogarty-146584">Brendan Gogarty</a>, Senior Lecturer / Clinical Director / Director (Acting) Tas Law Reform Institue, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> This article is republished from <a href="http://theconversation.com">The Conversation</a> under a Creative Commons license.

How bushfires create their own ferocious weather systems

As the <a href="https://theconversation.com/drought-and-climate-change-were-the-kindling-and-now-the-east-coast-is-ablaze-126750">east coast bushfire crisis unfolds</a>, New South Wales Premier Gladys Berejiklian and Rural Fire Service operational officer Brett Taylor have each warned residents bushfires can <a href="https://www.canberratimes.com.au/story/6486857/nsw-fire-emergency-what-all-the-terms-mean/">create their own weather systems</a>. This is not just a figure of speech or a general warning about the unpredictability of intense fires. Bushfires genuinely can create their own weather systems: a phenomenon known variously as firestorms, pyroclouds or, in meteorology-speak, <a href="https://www.nasa.gov/topics/earth/features/pyrocb.html">pyrocumulonimbus</a>. The occurrence of firestorms is increasing in Australia; there have been <a href="https://www.bnhcrc.com.au/news/2018/predicting-fire-thunderstorms">more than 50 in the period 2001-18</a>. During a six-week period earlier this year, 18 confirmed pyrocumulonimbus formed, mainly over the Victorian High Country. <img src="https://images.theconversation.com/files/301180/original/file-20191112-178498-1f0m8xr.JPG?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="" /> A pyrocumulonimbus cloud generated by a bushfire in Licola,Victoria, on March 2, 2019. Elliot Leventhal, Author provided Its not clear whether the current bushfires will spawn any firestorms. But with the frequency of extreme fires set to increase due to hotter and drier conditions, it’s worth taking a closer look at how firestorms happen, and what effects they produce. What is a firestorm? The term “firestorm” is a contraction of “fire thunderstorm”. In simple terms, they are thunderstorms generated by the heat from a bushfire. In stark contrast to typical bushfires, which are relatively easy to predict and are driven by the prevailing wind, firestorms tend to form above unusually large and intense fires. If a fire encompasses a large enough area (called “deep flaming”), the upward movement of hot air can cause the fire to interact with the atmosphere above it, potentially forming a pyrocloud. This consists of smoke and ash in the smoke plume, and water vapour in the cloud above. If the conditions are not too severe, the fire may produce a cloud called a pyrocumulus, which is simply a cloud that forms over the fire. These are typically benign and do not affect conditions on the ground. But if the fire is particularly large or intense, or if the atmosphere above it is unstable, this process can give birth to a pyrocumulonimbus – and that is an entirely more malevolent beast. What effects do firestorms produce? A pyrocumulonibus cloud is much like a normal thunderstorm that forms on a hot summer’s day. The crucial difference here is that this upward movement is caused by the heat from the fire, rather than simply heat radiating from the ground. Conventional thunderclouds and pyrocumulonimbus share similar characteristics. Both form an anvil-shaped cloud that extends high into the troposphere (the lower 10-15km of the atmosphere) and may even reach into the stratosphere beyond. <a href="https://images.theconversation.com/files/301195/original/file-20191112-178516-1qzj1pp.png?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/301195/original/file-20191112-178516-1qzj1pp.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="" /></a> NASA image of pyrocumulonimbus formation in Argentina, January 2018. NASA The weather underneath these clouds can be fierce. As the cloud forms, the circulating air creates strong winds with dangerous, erratic “downbursts” – vertical blasts of air that hit the ground and scatter in all directions. In the case of a pyrocumulonimbus, these downbursts have the added effect of bringing dry air down to the surface beneath the fire. The swirling winds can also carry embers over huge distances. Ember attack has been identified as the main cause of property loss in bushfires, and the unpredictable downbursts make it impossible to determine which direction the wind will blow across the ground. The wind direction may suddenly change, catching people off guard. Firestorms also produce dry lightning, potentially sparking new fires, which may then merge or coalesce into a larger flaming zone. In rare cases, a firestorm can even morph into a “<a href="https://theconversation.com/turn-and-burn-the-strange-world-of-fire-tornadoes-11193">fire tornado</a>”. This is formed from the rotating winds in the convective column of a pyrocumulonimbus. They are attached to the firestorm and can therefore lift off the ground. This happened during the infamous January 2003 Canberra bushfires, when a pyrotornado tore a path near Mount Arawang in the suburb of Kambah. <iframe width="440" height="260" src="https://www.youtube.com/embed/5H1eVy6O3Fo?wmode=transparent&start=0" frameborder="0" allowfullscreen=""></iframe> A fire tornado in Kambah, Canberra, 2003 (contains strong language). Understandably, firestorms are the most dangerous and unpredictable manifestations of a bushfire, and are impossible to suppress or control. As such, it is vital to evacuate these areas early, to avoid sending fire personnel into extremely dangerous areas. The challenge is to identify the triggers that cause fires to develop into firestorms. Our <a href="https://www.unsw.adfa.edu.au/science/research-clusters/applied-and-industrial-mathematics">research at UNSW</a>, in collaboration with fire agencies, has made considerable progress in identifying these factors. They include “eruptive fire behaviour”, where instead of a steady rate of fire spread, once a fire interacts with a slope, the plume may attach to the ground and rapidly accelerate up the hill. Another process, called “vorticity-driven lateral spread”, has also been recognised as a good indicator of potential fire blow-up. This occurs when a fire spreads laterally along a ridge line instead of following the direction of the wind. Although further refinement is still needed, this kind of knowledge could greatly improve decision-making processes on when and where to deploy on-ground fire crews, and when to evacuate before the situation turns deadly.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important; text-shadow: none !important;" src="https://counter.theconversation.com/content/126832/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/rachel-badlan-884363">Rachel Badlan</a>, Postdoctoral Researcher, Atmospheric Dynamics, <a href="http://theconversation.com/institutions/unsw-1414">UNSW</a> This article is republished from <a href="http://theconversation.com">The Conversation</a> under a Creative Commons license.

What you need to know about YouTube's algorithm system

People watch <a href="https://youtube.googleblog.com/2017/02/you-know-whats-cool-billion-hours.html">more than a billion hours</a> of video on YouTube every day. Over the past few years, the video sharing platform has <a href="https://www.thedailybeast.com/how-youtube-pulled-these-men-down-a-vortex-of-far-right-hate">come under fire</a> for its role in <a href="https://www.nytimes.com/2018/03/10/opinion/sunday/youtube-politics-radical.html">spreading</a> and <a href="https://www.theguardian.com/media/2018/sep/18/report-youtubes-alternative-influence-network-breeds-rightwing-radicalisation">amplifying</a> extreme views. YouTube’s video recommendation system, in particular, has been criticised for radicalising young people and steering viewers down <a href="https://policyreview.info/articles/news/implications-venturing-down-rabbit-hole/1406">rabbit holes</a> of disturbing content. The company <a href="https://youtube.googleblog.com/2019/01/continuing-our-work-to-improve.html">claims</a> it is trying to avoid amplifying problematic content. But <a href="https://dl.acm.org/citation.cfm?doid=3298689.3346997">research</a> from YouTube’s parent company, Google, indicates this is far from straightforward, given the commercial pressure to keep users engaged via ever more stimulating content. But how do YouTube’s recommendation algorithms actually work? And how much are they really to blame for the problems of radicalisation? The fetishisation of algorithms Almost everything we see online is heavily curated. Algorithms decide what to show us in Google’s search results, Apple News, Twitter trends, Netflix recommendations, Facebook’s newsfeed, and even pre-sorted or spam-filtered emails. And that’s before you get to advertising. More often than not, these systems decide what to show us based on their idea of what we are like. They also use information such as what our friends are doing and what content is newest, as well as built-in randomness. All this makes it hard to reverse-engineer algorithmic outcomes to see how they came about. Algorithms take all the relevant data they have and process it to achieve a goal - often one that involves influencing users’ behaviour, such as selling us products or keeping us engaged with an app or website. At YouTube, the “up next” feature is the one that receives most attention, but other algorithms are just as important, including search result rankings, <a href="https://youtube.googleblog.com/2008/02/new-experimental-personalized-homepage.html">homepage video recommendations</a>, and trending video lists. How YouTube recommends content The main goal of the YouTube recommendation system is to keep us watching. And the system works: it is responsible for more than <a href="https://www.cnet.com/news/youtube-ces-2018-neal-mohan/">70% of the time users spend</a> watching videos. When a user watches a video on YouTube, the “up next” sidebar shows videos that are related but usually <a href="https://www.pewinternet.org/2018/11/07/many-turn-to-youtube-for-childrens-content-news-how-to-lessons/">longer and more popular</a>. These videos are ranked according to the user’s history and context, and newer videos are <a href="https://storage.googleapis.com/pub-tools-public-publication-data/pdf/45530.pdf">generally preferenced</a>. This is where we run into trouble. If more watching time is the central objective, the recommendation algorithm will tend to favour videos that are new, engaging and provocative. Yet algorithms are just pieces of the vast and complex sociotechnical system that is YouTube, and there is so far little empirical evidence on their <a href="https://arxiv.org/abs/1908.08313">role</a> in processes of radicalisation. In fact, <a href="https://journals.sagepub.com/doi/full/10.1177/1354856517736982">recent research</a> suggests that instead of thinking about algorithms alone, we should look at how they interact with community behaviour to determine what users see. The importance of communities on YouTube YouTube is a quasi-public space containing all kinds of videos: from musical clips, TV shows and films, to vernacular genres such as “how to” tutorials, parodies, and compilations. User communities that create their own videos and use the site as a social network have played an <a href="https://books.google.com.au/books?id=0NsWtPHNl88C&source=gbs_book_similarbooks">important role</a> on YouTube since its beginning. Today, these communities exist alongside <a href="https://journals.sagepub.com/doi/full/10.1177/1329878X17709098">commercial creators</a> who use the platform to build personal brands. Some of these are far-right figures who have found in YouTube a home to <a href="https://datasociety.net/output/alternative-influence/">push their agendas</a>. It is unlikely that algorithms alone are to blame for the radicalisation of a previously “<a href="https://www.wired.com/story/not-youtubes-algorithm-radicalizes-people/">moderate audience</a>” on YouTube. Instead, <a href="https://osf.io/73jys/">research</a> suggests these radicalised audiences existed all along. Content creators are not passive participants in the algorithmic systems. They <a href="https://journals.sagepub.com/doi/10.1177/1461444819854731">understand how the algorithms work</a> and are constantly improving their <a href="https://datasociety.net/output/data-voids/">tactics</a> to get their videos recommended. Right-wing content creators also know YouTube’s policies well. Their videos are often “borderline” content: they can be interpreted in different ways by different viewers. YouTube’s community guidelines restrict blatantly harmful content such as hate speech and violence. But it’s much harder to police content in the grey areas between jokes and bullying, religious doctrine and hate speech, or sarcasm and a call to arms. Moving forward: a cultural shift There is no magical technical solution to political radicalisation. YouTube is working to minimise the spread of borderline problematic content (for example, conspiracy theories) by <a href="https://youtube.googleblog.com/2019/01/continuing-our-work-to-improve.html">reducing their recommendations</a> of videos that can potentially misinform users. However, YouTube is a company and it’s out to make a profit. It will always prioritise its commercial interests. We should be wary of relying on technological fixes by private companies to solve society’s problems. Plus, quick responses to “fix” these issues might also introduce harms to politically edgy (activists) and minority (such as sexuality-related or LGBTQ) communities. When we try to understand YouTube, we should take into account the different factors involved in algorithmic outcomes. This includes systematic, long-term analysis of what algorithms do, but also how they combine with <a href="https://policyreview.info/articles/news/implications-venturing-down-rabbit-hole/1406">YouTube’s prominent subcultures</a>, their <a href="https://arxiv.org/abs/1908.08313">role</a> in political polarisation, and their <a href="https://datasociety.net/pubs/oh/DataAndSociety_MediaManipulationAndDisinformationOnline.pdf">tactics</a> for managing visibility on the platform. Before YouTube can implement adequate measures to minimise the spread of <a href="https://journals.sagepub.com/doi/pdf/10.1177/0894439314555329">harmful content</a>, it must first understand what cultural norms are thriving on their site – and being amplified by their algorithms. <hr /> The authors would like to acknowledge that the ideas presented in this article are the result of ongoing collaborative research on YouTube with researchers Jean Burgess, Nicolas Suzor, Bernhard Rieder, and Oscar Coromina.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important; text-shadow: none !important;" src="https://counter.theconversation.com/content/125494/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/ariadna-matamoros-fernandez-577257">Ariadna Matamoros-Fernández</a>, Lecturer in Digital Media at the School of Communication, <a href="http://theconversation.com/institutions/queensland-university-of-technology-847">Queensland University of Technology</a> and <a href="https://theconversation.com/profiles/joanne-gray-873764">Joanne Gray</a>, Lecturer in Creative Industries, <a href="http://theconversation.com/institutions/queensland-university-of-technology-847">Queensland University of Technology</a> This article is republished from <a href="http://theconversation.com">The Conversation</a> under a Creative Commons license.

"There's still time": Why you should cash in your Qantas points before the system overhaul

In less than two weeks, Qantas frequent flyers will have to save up more points to redeem for flights as significant changes are set to take place. Starting September 18, reward seats in premium economy, business and first class will cost up to 18 per cent more in Qantas points, with the increases varying by route. The increased points requirement is balanced out by a reduction on the fees levied on reward flights. “On the other side they are reducing the taxes, so up to 50 per cent less fees are being charged for those reward tickets,” said the airline’s CEO Alan Joyce. In June, Qantas announced that its Frequent Flyers program would go through a <a href="https://www.qantasnewsroom.com.au/media-releases/qantas-rewards-frequent-flyers-in-program-overhaul/">major overhaul</a> over the next 12 months. Some of the changes include the addition of more than one million extra reward seats to more destinations on Qantas and new partner airlines, the opportunity to gain more flight and travel benefits through non-flying related transactions with partners in Points Club, and the introduction of Lifetime Platinum status. Flight Global Asia’s finance editor Ellis Taylor said the best way to make the best out of the changes is to redeem frequent flyer points before September 18. “At the end of the day, for airlines this is a financial obligation they have, and it goes on their balance sheets so if there’s a way to get people to spend more of their points to bring down that liability for them they’ll take it,” Taylor told <a href="https://www.9news.com.au/national/how-to-cash-in-your-qantas-frequent-flyer-points-before-overhaul-travel-news/df1452e1-b3a9-4c6d-bde7-7c8240a9b1c3">9News</a>. The Champagne Mile publisher Adele Eliseo advised travellers to nab an upgrade for their future Qantas flight, book a first class flight for short trips or a premium Classic Reward seat to popular northern hemisphere such as Europe and the United States before the changes kick in. “While many travellers will be sad to see these award chart increases kick in, there’s still time to lock in your dream redemption with Qantas points before September 18,” she wrote on <a href="https://www.news.com.au/travel/travel-advice/money/you-have-two-weeks-to-redeem-your-qantas-points-before-controversial-changes-start/news-story/81d635b6337484b56dea156b4644d9da">news.com.au</a>. “So, it’s time to get booking.”

Travel Tips

The strict new rules at Machu Picchu

Machu Picchu is on a number of people’s bucket lists as one of the destinations to see before they pass and seeing photos of the Incan ruins makes it easy to understand why. However, as interest in Machu Picchu continues to rise, access to the area has become limited. New ticketing systems have been put in place to limit tourists to visit at specifically scheduled times. Tickets, once you purchase them, are valid for four hours and re-entry is often not allowed. You either book in for a “morning” or an “afternoon” slot at a cost of 152 peruvian Sol ($NZD69). Officials introduced the ticketing system as a way to control crowds heading to the Incan ruins. In 2018, <a href="https://redirect.viglink.com/?format=go&jsonp=vglnk_155720760880212&key=a426d7531bff1ca375d5930dea560b93&libId=jvdd31lr0102i8oq000DAbjkeg2lp&loc=https%3A%2F%2Fedition.cnn.com%2Ftravel%2Farticle%2Fmachu-picchu-ticket-policy%2Findex.html&v=1&out=https%3A%2F%2Fcnn.com%2Ftravel%2Farticle%2Fovertourism-solutions%2Findex.html&ref=https%3A%2F%2Fwww.google.com%2F&title=Machu%20Picchu%20enforces%20strict%20ticket%20policy%20%7C%20CNN%20Travel&txt=CNN%20Travel%20talked%20to%20Sarah%20Miginiac">CNN Travel</a> spoke to Sarah Miginiac, who is the general manager for South America at adventure company G Adventures. She spoke about over tourism at Machu Picchu. "That's not what over tourism in Machu Picchu looks like," she says. In Peru's ancient city, it's a question of too many people trying to gain access. "There isn't the infrastructure around it," she said. She also stressed the need for a lasting solution that’s needed to control future tourism at the Incan ruins. "[The government] definitely need to make sure that whatever solution is going to be found to access Machu Picchu is actually a solution that will enable growth for the future as well, and not only for the current amount of passengers," said Miginiac.

Do you believe in reincarnation?

A majority of people have a general idea about reincarnation. The concept implies that upon death, your soul, mind or consciousness is transferred into a newborn. Some people write this off as a spiritual concept, but some scientists believe it to be true. Dr Ian Stevenson, who was a former Professor of Psychiatry at the University of Virginia School of Medicine dedicated his career to finding evidence of reincarnation until his death in 2007. He claimed to find over 3,000 examples of reincarnation, which he shared with the scientific community. In a study titled “<a href="https://med.virginia.edu/perceptual-studies/wp-content/uploads/sites/360/2016/12/STE39stevenson-1.pdf">Birthmarks and Birth Defects Corresponding to Wounds on Deceased Persons</a>”, Stevenson used facial recognition to analyse similarities between the claimant and their alleged prior incarnation. He wrote, according to <a href="https://www.express.co.uk/news/science/716499/reincarnation-REAL-proof-life-after-death">Express UK</a>: “About 35 per cent of children who claim to remember previous lives have birthmarks and/or birth defects that they (or adult informants) attribute to wounds on a person whose life the child remembers. The cases of 210 such children have been investigated. “In 43 of 49 cases in which a medical document (usually a postmortem report) was obtained, it confirmed the correspondence between wounds and birthmarks (or birth defects).” Stevenson also interviewed three children who claimed to remember aspects of their past lives. Stevenson wrote in an article: “It was possible in each case to find a family that had lost a member whose life corresponded to the subject’s statements. “The statements of the subject, taken as a group, were sufficiently specific so that they could not have corresponded to the life of any other person. “We believe we have excluded normal transmission of the correct information to the subjects and that they obtained the correct information they showed about the concerned deceased person by some paranormal process.” He’s not the only one who believes in reincarnation. Author Barry Eaton has written a new book called Past Lives Unveiled that goes into more detail about reincarnation and covers topics such as why children have a better memory of past lives. Eaton explains the concept of reincarnation below: “Living multiple lives over countless years provides us with the opportunity to have as many experiences as needed to understand ourselves and our place in the universe as a part of ‘all that there is.’” His book includes numerous case studies, including personal recounts of his own past lives. Do you believe in reincarnation? Let us know in the comments.
