Having the ‘right’ friends may hold the secret to building wealth, according to new study on socioeconomic ties

<p><em><a href="https://theconversation.com/profiles/brad-cannon-2216202">Brad Cannon</a>, <a href="https://theconversation.com/institutions/binghamton-university-state-university-of-new-york-2252">Binghamton University, State University of New York</a></em></p> <p>Having wealthy people in your social network significantly boosts the likelihood that you’ll participate in stock markets and savings plans, according to a new working paper I co-authored.</p> <p>My colleagues and I <a href="https://www.nber.org/system/files/working_papers/w32186/w32186.pdf">recently conducted research</a> on social finance to understand the ways in which social networks affect stock market participation and savings behavior. This is important because a substantial fraction of households in the U.S., particularly <a href="https://www.axios.com/2023/10/18/percentage-americans-own-stock-market-investing">lower-income families, do not own stocks</a>.</p> <p>Given that the total return to the U.S. stock market from 1980 through September 2024 has been over 12,000% – for example, US$1,000 <a href="https://ofdollarsanddata.com/sp500-calculator/">invested in the S&amp;P 500</a> in 1980 would be worth $121,350 today – this creates a disparity in wealth for those who participate relative to those who do not. Understanding why some people invest and others don’t is important for addressing social concerns such as rising inequality.</p> <p>In our study, we looked at <a href="https://academic.oup.com/ej/advance-article/doi/10.1093/ej/ueae074/7720537">social capital</a>, which is a measure of the value that comes from being in a group or having dense social networks. Researchers have found that social capital can have positive impacts on individuals and communities, spurring innovation, <a href="https://www.nature.com/articles/s41586-022-04996-4">economic prosperity</a> and better health outcomes. We used friendship data from Facebook to measure different aspects of social networks by county in the U.S. We combined this data with tax information from the Internal Revenue Service about investments and savings.</p> <p>We found that in counties where friendships with prosperous individuals are more common, investment and savings tend to be higher. Moreover, we found that having these friendships with wealthy individuals plays a more important role in shaping financial behaviors than two other aspects of social capital we looked at in our study: having a tight group of friends and living in a community with strong civic engagement.</p> <p>Of course, making wealthy friends alone does not guarantee you’ll invest or save more. But perhaps knowing people who invest makes it less daunting and fraught, particularly if those friends can serve as a resource and sounding board.</p> <p><em>“Friends with Benefits: Social Capital and Household Financial Behavior” was co-authored by <a href="https://www.marshall.usc.edu/personnel/david-hirshleifer">David Hirshleifer</a> and <a href="https://hankamer.baylor.edu/person/joshua-thornton">Joshua Thornton</a>.</em><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;" src="https://counter.theconversation.com/content/239370/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/brad-cannon-2216202">Brad Cannon</a>, Assistant Professor of Finance, <a href="https://theconversation.com/institutions/binghamton-university-state-university-of-new-york-2252">Binghamton University, State University of New York</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Borrowing money isn’t always a bad thing – debt can be a sensible way to build wealth

<p><em><a href="https://theconversation.com/profiles/bomikazi-zeka-680577">Bomikazi Zeka</a>, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a></em></p> <p>Debt, in some form or another, is part of our financial profiles whether we like it or not. And it can be a useful way to build wealth if it is managed carefully and wisely.</p> <p>For example, you may borrow money from the bank to buy an asset – a resource of economic value that generates income from its productive use. Investment property is an example.</p> <p>So investing in an income-producing property can be a good idea.</p> <p>If you are already in the property market, the home equity you’ve accumulated – the share of the property value that’s yours – can help you buy a second property. This time, you may not need a deposit as big as the initial investment.</p> <p>In the event that the rental market is booming and your tenants pay you more than what you repay on the loan, municipal rates and property manager fees, then the wealth-building machine will start to run itself.</p> <p>But debt makes many people uncomfortable.</p> <p>In South Africa, a person earning R20,000 a month commits on average <a href="https://businesstech.co.za/news/finance/585372/south-africas-middle-class-is-in-serious-trouble-right-now/">63% of their salary to repaying unsecured debt</a> – such as credit cards, personal loans, overdrafts or “buy now, pay later” facilities. As a general guideline, it’s suggested that <a href="https://www.investopedia.com/terms/d/dti.asp">no more than 40%</a> of your income should be used to service debt.</p> <p>Financial anxiety has its roots in some misconceptions. The main one is that all debt is bad. This isn’t true. Prudent borrowing to buy an asset can help build wealth in the medium to long term. So fears about debt need to be weighed against a broader understanding of wealth accumulation. Well-managed debt can play a role in that process.</p> <p>Here are the four biggest misconceptions about debt. Recognising them will help you develop a more nuanced approach to debt.</p> <h2>The misconceptions</h2> <p><strong>All debt is bad debt.</strong></p> <p>Indeed, debt is a problem when you can no longer manage it and it starts to manage you. One of the simplest ways to tell whether debt is working for you or against you is through “leveraging”. This refers to the use of debt to acquire an asset that is worth more than the value of the debt. It’s also known as positive or favourable leveraging.</p> <p>People who take out unsecured loans are leveraging unfavourably when the debt is driven by consumption. Often there’s nothing to show for what you’ve spent. Unsecured loans also tend to charge higher interest rates to compensate for the lack of collateral.</p> <p><strong>Only financially reckless people are in debt.</strong></p> <p>This is the next misconception. Second to unsecured loans, most South African consumer debt portfolios are taken up by <a href="https://businesstech.co.za/news/wealth/617685/these-income-levels-in-south-africa-owe-the-most-debt/">home loans</a>. The most realistic way to gain entry into the housing market is through a mortgage. You’re doing the right thing if your mortgage is paid off within a reasonable time. This will mean that, in the long term, the value of the property will surpass the home loan amount that was taken out to buy the property in the first place.</p> <p>But there are two misconceptions related specifically to mortgages.</p> <p><strong>After you’ve paid the mortgage deposit, you won’t have other fees to pay.</strong></p> <p>This isn’t correct. Banks charge a fee to open and close a home loan account. There can also be a penalty when a home loan is repaid prematurely. So be sure to read the fine print about discharge fees or closing costs.</p> <p><strong>If you stick to the repayment amount for your mortgage, you’ll be able to repay the loan quickly.</strong></p> <p>This isn’t true – even if interest rates fall and your mortgage repayments decline, your home loan is most likely tied to a loan term of 20 to 30 years. Many banks will quote a monthly mortgage repayment amount that seems affordable at face value but is in fact based on a 20-year term period.</p> <p>Banks are businesses and it works in their favour if you take longer to repay your mortgage because that translates into more interest repayments. The longer the duration of the home loan, the more interest you pay, the more profit they make.</p> <p>If it takes over 20 years to repay a bond, it’s often the case that the value of the interest repayments exceeds the initial loan amount.</p> <p>Home loan calculators are a useful tool that can help you assess how much you could afford to repay on a home loan depending on the deposit saved, if interest rates change and how long it will take you to repay the mortgage with topped-up contributions.</p> <p>It is essential to have a goal for when you’d like to finish paying off your mortgage and a plan in place to achieve this goal. If you don’t do this you could become a mortgage prisoner.</p> <h2>Keeping your eye on the prize</h2> <p>As we’re about to conclude the year and enter the festive season, it’s a good time to remember your financial goals and not let your guard down by unconsciously swiping or tapping that credit card.</p> <p>“Janu-worry” is around the corner, and so is the financial anxiety that comes with it. But it need not be the case. Debt can either be the cure or the cause of your financial position. Reconsider spending patterns that prompt you to use your credit card. Too much debt over short periods is an irregular spending pattern that is a warning sign.</p> <p>There’s no harm in buying what you can afford or staying in your financial lane if the alternative forces you to sacrifice your hard-earned income on servicing consumption-driven debt.</p> <p>For better or worse, debt is a part of our financial portfolios. But the road to financial empowerment is not always easy – financial planning can help you keep your eye on the prize.<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;" src="https://counter.theconversation.com/content/192630/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/bomikazi-zeka-680577"><em>Bomikazi Zeka</em></a><em>, Assistant Professor in Finance and Financial Planning, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Battling to make ends meet? Financial planning expert offers 5 tips on how to build your budget

<p><em><a href="https://theconversation.com/profiles/bomikazi-zeka-680577">Bomikazi Zeka</a>, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a></em></p> <p>Every day seems to bring new headlines about rising costs. <a href="https://www.news24.com/news24/africa/news/nigerias-big-unions-call-indefinite-strike-over-fuel-prices-and-the-cost-of-living-20230926">In Nigeria</a>, unions are threatening to strike amid soaring fuel prices; the country’s inflation rate <a href="https://www.cbn.gov.ng/rates/inflrates.asp">hit 25%</a> in August. The amount it costs to fill a food basket in South Africa <a href="https://pmbejd.org.za/wp-content/uploads/2023/09/PMBEJD_Key-Data_September-2023_27092023.pdf">keeps climbing</a>. Ghanaians <a href="https://www.reuters.com/world/africa/multi-day-protests-over-economic-crisis-grip-ghanas-capital-2023-09-23/">took to the streets</a> of Accra in late September to protest about the cost of living.</p> <p>A <a href="https://www2.deloitte.com/us/en/insights/industry/retail-distribution/consumer-behavior-trends-state-of-the-consumer-tracker.html">recent study by the audit and consulting firm Deloitte</a> found that 75% of South Africans were concerned that the prices for everyday purchases would continue to increase, while 80% of consumers across all income groups expected the prices of groceries, household utilities and fuel to rise.</p> <p>This stark reality means budgeting may be more necessary than ever.</p> <p>If you don’t know how to create a budget, then you shouldn’t feel bad – most adults aren’t taught how to create one. And most people don’t budget, because they see it as restrictive or unsustainable. But it need not be: once you appreciate that a budget can work for you, it can be a financially empowering exercise. It’s a cornerstone of financial planning because it ensures you are living within your means and helps you remain in financial control.</p> <p>As a financial planning academic, I focus in <a href="https://researchprofiles.canberra.edu.au/en/persons/bomikazi-zeka/publications/">my research</a> on improving financial wellbeing and promoting savings behaviours through interventions such as budgeting. Here are five guidelines for creating a budget.</p> <h2>1. Apps vs spreadsheet</h2> <p>A good place to start is to choose the format of how you’re going to budget. There are several <a href="https://www.sanlamreality.co.za/wealth-sense/setting-up-a-family-budget-that-works/">online templates</a> and apps you can use for budgeting. For instance, <a href="https://www.22seven.com/">22Seven</a> has gained popularity in South Africa due to its compatibility with several financial institutions, including the country’s big five banks. Similarly, <a href="https://www.the-star.co.ke/business/kenya/2021-01-25-budgeting-using-mint-app/">Mint</a> is a popular budgeting tool that is used in Kenya and Nigeria.</p> <p>If you prefer to put pen to paper, some online templates come with <a href="https://www.wonga.co.za/blog/free-budget-template">free printable budgets</a>. Creating your own <a href="https://create.microsoft.com/en-us/learn/articles/how-to-make-excel-budget">Excel spreadsheet</a> is an equally good approach.</p> <p>What matters most is using a tool that you can commit to.</p> <h2>2. Itemising your income and expenses</h2> <p>A budget essentially shows how much you’re spending in relation to how much you’re earning. So once you have selected your budgeting tool, you need to fill in your income and itemise how much you’re spending on each expense in a month. A budget can be considered a cashflow statement because it allows you to track money coming in (income) and money going out (expenses).</p> <p>If you are living within your means, your budget should indicate a surplus – more cash inflows than cash outflows. So budgeting provides an accurate account of your short-term financial position.</p> <h2>3. A realistic account of expenses</h2> <p>When you look at your financial statements, fill your expenses into your budget honestly and accurately. Don’t cheat! Since everyone’s financial situation is different, your budget will also be unique.</p> <p>Even though there is no one-size-fits-all approach to budgeting, it should still consider all of your expenses (both regular and intermittent). A general rule of thumb is that if it’s deducted from your account then you should treat it as an expense. This includes payments for housing, medical insurance, fuel, dining out, credit card repayments and even bank fees.</p> <h2>4. Save first, spend later</h2> <p>Now you’ve seen how much you’re spending. Either it’s too much – and you can plan where to cut back – or you have savings at the end of the month.</p> <p>When compiling your budget it’s important to demarcate how much will be in the form of savings. What’s more important is getting into the habit of saving before you spend instead of saving after spending. If you spend first then you’ve deprived yourself of the opportunity to save for a rainy day.</p> <p>Furthermore, <a href="https://eprints.hud.ac.uk/id/eprint/10231/1/Microsoft_Word_-_submitted_version_3rd_June_201.pdf">research</a> has shown that getting into the habit of saving has a transgenerational effect: it can be considered a cultural value that is passed on from one generation to another. So think of saving as paying yourself first. Once you have done so, you won’t feel guilty for treating yourself because you’ve already done the financially responsible thing by putting your savings aside.</p> <h2>5. Considering assets and liabilities</h2> <p>Once you’ve become comfortable with consistently budgeting, you can take it up a notch by including your assets (everything you own with an economic value) and liabilities (everything you owe) to determine your overall financial position.</p> <p>You can get a clearer picture of your overall financial wellbeing by compiling a list of all your assets, for example your savings and <a href="https://www.investopedia.com/terms/h/home_equity.asp">home equity</a>, in relation to liabilities (such as bank loans). Knowing your long-term financial position can indicate how financially resilient or vulnerable you are. In the event of a financial emergency, you will know which resources you can draw upon to meet an unexpected expense.</p> <p>By creating a budget (and sticking to it), you can protect yourself and your household from financial shocks. Consider the alternative. Imagine you haven’t budgeted and set savings aside. If a financial emergency were to arise, your next best bet would be to borrow the funds you need. You’d have to come up with a plan to repay what you’d borrowed while also building your savings.</p> <h2>A healthy habit</h2> <p>Getting into the habit of budgeting isn’t easy, especially if you haven’t done it before or you’re intimidated by the process. But, as the expression goes, “a journey of a thousand miles begins with a single step”. Think of budgeting as taking a small but important step towards reclaiming control over your finances and improving your financial well-being.<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;" src="https://counter.theconversation.com/content/214861/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/bomikazi-zeka-680577">Bomikazi Zeka</a>, Assistant Professor in Finance and Financial Planning, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Clive Palmer's plans to build Titanic II resurface

<p>Just when you thought we'd exhausted all of the possible billionaire pet projects, Clive Palmer, the Queensland mining magnate with pockets deeper than the Mariana Trench, has once again proven us wrong.</p> <p>For more than a decade now, Palmer has harboured a peculiar obsession: resurrecting the ghost of the <em>Titanic</em>, the world's most infamous maritime disaster.</p> <p>Palmer wants to build <em>Titanic II</em>, because when you've got more money than you can count, why not embark on a maritime venture that's already synonymous with catastrophe?</p> <p>Palmer, with the audacity only wealth can afford, has been pushing for this <em>Titanic</em> replica since 2012. Not content with merely one failed attempt, he launched the project again in 2018. Now, after another six years and a global pandemic, he's dusting off his captain's hat and setting sail once more, announcing the <em>Titanic II</em>'s re-launch at the Sydney Opera House (because when you're Clive Palmer, a press conference venue like the local community centre just doesn't cut it).</p> <p>But why, you may ask? According to Palmer himself, it's a simple matter of economics: "I’ve got two options, either give my wife more money for shopping or spend it on the <em>Titanic</em> and I’m spending it on the Titanic because she’s shopped enough."</p> <p>Ah, yes, the age-old dilemma of whether to buy your spouse another designer handbag or fund a one-billion-dollar replica of a ship that sank over a century ago. We've all been there.</p> <p>Despite the naysayers who dismissed Palmer's dream as nothing more than the folly of a rich eccentric, he remains undeterred. Now, with the pandemic in the rearview mirror and cruise ships once again cruising, Palmer sees this as the perfect time to resurrect his <em>Titanic</em> dream. Because what better way to celebrate the end of a global health crisis than by building a monument to maritime tragedy?</p> <p>Palmer assures us that this time around, things will be different. The plans are similar to previous iterations, but now they comply with current regulations. Tenders are being sought, with plans to confirm a shipbuilder by year's end with the intention of setting sail by 2027.</p> <p>And what can prospective passengers expect from this seafaring spectacle? Well, according to Palmer's team, an eight-minute video featuring period costumes and a layout straight out of the early 1900s. Passengers will even be encouraged to dress the part (though that's not compulsory; nothing screams "fun vacation" like wearing corsets and three-piece suits in the middle of the ocean).</p> <p>But fear not, third-class passengers, you won't be left out of this <em>Titanic</em> experience. You'll get to enjoy stew and mash at communal dining tables, just like the good old days. Although, for those who prefer their meals without a side of historical accuracy, other options will be available. </p> <p>In amongst of all this, Palmer has grandiose visions of <em>Titanic II</em> as a symbol of world peace. “We all know how to make war," he announced at the press launch. "We get armies and we fund wars. People know about that. But it is a lot harder to make peace. To make peace you have got to stick with it every day. You progress inch by inch.</p> <p>“<em>Titanic ll</em> is something that can provide peace. It can be a ship of peace between all countries of the world. Millions have dreamt of sailing on her, seeing her in port and experiencing her unique majesty. <em>Titanic ll</em> will be the ship where those dreams come true.”</p> <p>So, as Palmer sets sail on his quixotic quest to recreate history, we can't help but wonder: Is <em>Titanic II</em> a testament to human ingenuity or just another billionaire's folly? Only time will tell. But if history has taught us anything, it's that sometimes, even the grandest dreams can end up at the bottom of the ocean.</p> <p><em>Images: Rod Eime / Wikimedia</em></p>

How to stop self-criticising and build yourself up instead

<p><strong>Stop the self-harm</strong></p> <p>It won’t hurt as much when you say something mean about me if I say it about myself first. For decades, this had been my mantra, a type of self-defence mechanism I developed as a kid against those who would criticise, bully or belittle me. On one hand, it made me humble, aware of my flaws and open to improving myself. On the other, self-criticising stunted my ability to be confident and trust my gut.</p> <p>The self-criticism quickly took on a life of its own – to the point where I was constantly trying to anticipate what people might not like about me and then beat them to the punchline. “I know I can be too much, and you’re probably sick of me,” I’d tell friends, which was a statement born less out of self-awareness and more out of fear. That sort of self-deprecating remark made it impossible to love myself, put others in an awkward position and backfired on quite a few occasions. A new friend once quipped, “If that were true, why would I be friends with you? Are you saying I have bad taste in friends?”</p> <p>That hit hard. For people who didn’t have good intentions, well, I’d just handed them a laundry list of all my insecurities. What I was really saying was I’m afraid you’ll hurt me, so I’ll hurt myself first. That’s a pretty harsh way to live life. Luckily, there’s a path out of the self-criticising trap. I talked to the experts to find out why we’re so good at putting ourselves down – and how to stop.</p> <p><strong>Why do we criticise ourselves so much?</strong></p> <p>I’m not the only one who made self-criticising a personality trait. In fact, a lot of women are conditioned to be this way, says psychologist Dr Traci Stein, who is also an author and creator of a series of programs to fight critical self-talk and build self-compassion.</p> <p>“Having negative thoughts about ourselves is human nature. We all want to fit in, be accepted and not be ostracised,” she explains. “We are all under a lot of pressure to measure ourselves according to other people’s evaluations and expectations. So we subconsciously fixate on something to ‘fix’ so we will feel loved and accepted.”</p> <p>The irony of these thoughts is that while they’re based on a desire to fit in and feel accepted in our community, they often have the opposite result, says Latasha Blackmond, author of Be You, No Filter: How to Love Yourself and Stay #SocialMediaStrong. “Over time, self-criticism does the very thing you’re afraid of: It isolates you by making you very self-centred and, yes, selfish. You’re too busy worrying about yourself to love and help others,” she says.</p> <p>Ouch.</p> <p><strong>What is self-criticism and how do you spot it?</strong></p> <p>Self-criticism is any thought that highlights a flaw or problem you have – or think you have (as Stein points out, critical thoughts are often untrue). These negative thoughts can become ingrained so deeply in your inner voice that they become hard to recognise in the moment.</p> <p>You can identify these thoughts, she says, because they are often self-defeating and repetitive, leading to feelings of insecurity, confusion, self-doubt, sadness and anger. The connection between self-criticising thoughts and negative emotions is so strong that many people with chronic depression find that a habit of severe self-criticism is at the core of their mental illness.</p> <p>Often tell yourself you’re a massive failure? That’s self-criticism. Other examples of self-critical thoughts include:</p> <ul> <li>I’ll never be good enough. I’ve always failed at everything I try.</li> <li>I don’t deserve to be loved.</li> <li>I hate myself.</li> <li>If only I were richer, thinner, prettier or smarter. Then people would like me.</li> <li>I don’t deserve good things, but I deserve all the bad things.</li> <li>I’m so annoying. Everyone must hate me.</li> </ul> <p>These are just the tip of the garbage iceberg. Self-criticism can cover any area of your life, including your body, relationships, sexual encounters, career, finances, goals, hobbies, family and education – even your life in general, Stein says.</p> <p><strong>What is the harm in self-criticising?</strong></p> <p>On a basic level, being able to recognise our own faults benefits us because it gives us a chance to correct them and improve. But this is different from the type of malignant self-criticising many people engage in, Blackmond says. “Self-criticism is rarely productive and often impedes growth,” she says. “You start to believe all the bad things you are saying about yourself, which can then turn into a self-fulfilling prophecy. This, in turn, leads to anxiety and depression, creating a vicious cycle of negativity.”</p> <p>Case in point: You tell yourself you’re too dumb to get the promotion at work, so you don’t even try. When you don’t get the promotion, you tell yourself that proves you were right. You beat yourself up for your “failure,” which reinforces the belief that you are dumb, starting the whole cycle over again.</p> <p>“People who are very self-critical lack the confidence to make mistakes they can learn from. Fearing they aren’t good enough can lead to struggles at school, work and in general, and can lead someone to avoid any situation that generates more worry and self-doubt,” Stein says, adding that these people are also more likely to end up in toxic or abusive relationships.</p> <p>Another issue arises when self-criticism framed as self-improvement turns into excessive worrying, Stein says. “So someone might wind up worrying about an awful lot of things, from whether they are ‘good enough’ in some way to excessive worrying about their health, safety or competence – even if there is no objective evidence suggesting they have something to worry about,” she explains. “These worries take up a lot of time and energy.”</p> <p><strong>How to stop self-criticising once and for all</strong></p> <p>The good news about these negative thoughts is they are just that: thoughts. And you can change your thoughts, Blackmond says. It starts by cultivating a positive mindset through self-compassion. “Be aware of the negative thoughts and interrupt that internal dialogue,” she says. “Change them into something positive. Speak to yourself kindly, like you would to someone you love and care about. You’d never tell your child that they are stupid and ugly, so don’t speak to yourself that way either.”</p> <p>Easier said than done? Here are 12 tips from our experts that will help you cultivate self-compassion and nix harmful critical thoughts.</p> <p><strong>1. Celebrate imperfections </strong></p> <p>Kintsugi is a Japanese art form that repairs broken pottery with gold, highlighting the “flaws” and showing the beauty in breaking down and repairing. Look for kintsugi in your life, metaphorically and physically. “Look to art, music, poetry and prose, drama and [other areas] that celebrate imperfection and see it as a gift, not a flaw to be hidden,” Blackmond says.</p> <p><span style="text-decoration: underline;"><em>Try this:</em></span> Start by reading body-positivity quotes and confidence quotes. For a hands-on lesson in the beauty of imperfections, get a kintsugi craft kit. Or watch a play, read a book or listen to a song that celebrates our flaws.</p> <p><strong>2. Be less judgemental of others</strong></p> <p>People who are harshly critical of others are usually harshly critical of themselves as well, so learning to offer others grace and compassion can open the door to doing the same for yourself, Blackmond says. “It’s about not seeing the world as black or white, good or bad,” she says.</p> <p><span style="text-decoration: underline;"><em>Try this:</em></span> Whenever you catch yourself thinking negatively of someone else – from your sister to a celebrity to a terrible driver – stop the thought and offer a more compassionate take. Let’s say your mind automatically thinks What kind of idiot can’t park between the lines? Replace the thought with a kinder take: This person must have been in a big hurry or having a bad day. I hope things get better for them.</p> <p><strong>3. Delete your social media apps</strong></p> <p>Or at least lessen the amount of time you spend on them. “Social media can have this immense impact on our self-esteem because it encourages us to compare our worst selves to other people’s best selves,” Blackmond says. Besides, what you see is often photoshopped or cherry-picked.</p> <p><span style="text-decoration: underline;"><em>Try this:</em></span> Stop comparing yourself to others. Limit your time on social media to one hour or less per day. Curate your feed, and unfollow anyone who makes you feel bad about yourself.</p> <p><strong>4. Get therapy</strong></p> <p>Self-critical thoughts can be really sticky, especially if you’ve made a habit of them, Stein says. “A good therapist will help you learn to recognise these thoughts, challenge them and come up with anxiety-management strategies,” she says. “They can also act as a mirror, helping you see yourself in a more accurate light.”</p> <p><span style="text-decoration: underline;"><em>Try this:</em></span> Find a therapist who specialises in self-compassion or read a book about self-compassion.</p> <p><strong>5. Do a mindfulness meditation</strong></p> <p>Mindfulness is simply the practice of being present in the here and now, and when you’re focused on this moment, you can’t beat yourself up by looking to the past with regret or looking to the future with worry, Stein says. “Mindfulness meditation is a powerful tool for learning to reframe or stop self-critical thoughts,” she says.</p> <p><span style="text-decoration: underline;"><em>Try this:</em></span> Download a meditation app like Calm, Headspace or The Mindfulness App, and do a daily guided mindfulness meditation. Don’t worry about acing the practice on day one. Being mindful is a learned skill, and mindfulness meditation is useful even at the beginner stage.</p> <p><strong>6. Use self-deprecating humour sparingly </strong></p> <p>Making other people the butt of your jokes is cruel… and so is making yourself the butt of the joke. “A little self-deprecating humour in the right situation can help defuse tension and build relationships, but a little goes a long way,” Blackmond says. Heavy-handed self-deprecating humour makes others uncomfortable, and it can affect how you see yourself.</p> <p>“Be very careful with how you speak about yourself, even in a joking way,” she says. “Better yet, pick a different type of humour to bond over.”</p> <p><span style="text-decoration: underline;"><em>Try this:</em></span> Brush up on your public speaking, and if you’re going to crack a joke, pick one that has nothing to do with you.</p> <p><strong>7. Go outside </strong></p> <p>Self-criticism makes your world get smaller and smaller as you limit yourself. The antidote? Make your world bigger. “When you find yourself getting trapped in a cycle of negativity, go outside and take a walk,” Blackmond says. Breathe the fresh air, look at the sunset, say hi to your neighbours, pick up a little trash along the way – all these things will help you instantly feel better about yourself and the world.</p> <p><span style="text-decoration: underline;"><em>Try this:</em></span> Take a walk outdoors each day and boost both your mental and physical health. Listen to some confidence-boosting songs in the process to really break your negative mindset.</p> <p><strong>8. Learn a new hobby</strong></p> <p>From painting to computer coding to rock climbing, trying new things helps you focus on the positive while “proving” the negative thoughts wrong. The trick, Blackmond says, is to go into it with a positive attitude. Be open to new things and accept that failing is a part of the learning process. “It’s OK to fail,” she says. “Expect mistakes as part of the learning process – celebrate them.”</p> <p><span style="text-decoration: underline;"><em>Try this:</em></span> Sign up for a class, find a new hobby or go back to an activity you used to love.</p> <p><strong>9. End toxic relationships </strong></p> <p>“A lot of us are self-critical because we were criticised early on by parents or other loved ones,” Stein says, adding that people often see this type of criticism as good because it’s “done out of love.” But this is not loving behaviour.</p> <p>“Go where you’re celebrated,” Blackmond says. “Everyone deserves to be celebrated and lifted up by their loved ones.”</p> <p><span style="text-decoration: underline;"><em>Try this:</em></span> Break the cycle by keeping relationships with only those people who build you up and encourage you to grow. Avoid people who use “brutal honesty” or “tough love” to show their care. Stand up for yourself and kick those toxic relationships to the curb.</p> <p><strong>10. Try cognitive behavioural therapy</strong></p> <p>Cognitive behavioural therapy (CBT) and its companion, dialectical behavioural therapy (DBT), are powerful psychological tools for reframing negative thoughts and learning how to think more positively, Stein says. “CBT helps people become more aware of the specific, core beliefs behind all of these in-the-moment worries and identify what is triggering the negative self-talk,” she explains. They sound technical, but the concepts are simple, and anyone can implement them with practice.</p> <p><span style="text-decoration: underline;"><em>Try this:</em></span> Even if you have to get out of your comfort zone a little, it’s worth signing up for a course of CBT. Not ready for that? Do a CBT workbook at home.</p> <p><strong>11. Help other people</strong></p> <p>The fastest way to feel more positively about yourself is to do something positive in the world, Blackmond says. “Self-criticism is inherently selfish. Serving others is selfless,” she says. “Pure altruism sparks a cascade of love and positivity that fills you and radiates outwards.”</p> <p><span style="text-decoration: underline;"><em>Try this:</em></span> Do something for someone who can’t do anything for you, she suggests. For instance, volunteer at a local school or food bank. Not only will you be doing some good in the world, but you’ll reap the many benefits of volunteering.</p> <p><strong>12. Use self-reflection instead of self-criticism </strong></p> <p>No one is saying that you need to think you’re perfect exactly the way you are, or there’s no room for improvement. Rather, Blackmond says, you should be looking honestly and realistically at your flaws. The trick is to do it in a positive way. Self-reflection encourages insight and action based on self-love and a desire to do better and be better, she explains. Self-criticism stops that process, trapping you in a cycle of negativity and stunting your growth.</p> <p><span style="text-decoration: underline;"><em>Try this:</em></span> Keep a journal of the things you like about yourself and the things you can improve on. Practice gratitude for yourself and others. Make positive goals to help you progress in those areas, track your progress and celebrate your successes.</p> <p><strong>Stop the self-criticising cycle </strong></p> <p>“At the core of every self-critical belief is the question ‘Am I lovable and worthy of love the way I am?’ And the answer is yes, you are,” Stein says. Too many people, like me, use self-criticism as a self-defence tool, and it cuts us off from the very love and acceptance we crave.</p> <p>Learning how to build emotional strength and quiet that critical self-talk through self-compassion is the key to stronger relationships and a happier life. “You’ve only got this one life, so don’t waste it on regret and worry,” she says.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/healthsmart/conditions/mental-health/how-to-stop-self-criticising-and-build-yourself-up-instead?pages=1" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

What does a building need to call itself ‘accessible’ – and is that enough?

<p><a href="https://theconversation.com/profiles/ilan-wiesel-303040">Ilan W<em>iesel</em></a><em>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> and <a href="https://theconversation.com/profiles/rebecca-bentley-173502">Rebecca Bentley</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a></em></p> <p>The <a href="https://www.ndisreview.gov.au/resources/reports/working-together-deliver-ndis">National Disability Insurance Scheme (NDIS) review</a> and the disability royal commission’s <a href="https://disability.royalcommission.gov.au/system/files/2023-09/Final%20Report%20-%20Volume%207%2C%20Inclusive%20education%2C%20employment%20and%20housing%20-%20Part%20C.pdf">final report</a> both highlighted the crucial role of accessible buildings and homes in ensuring the inclusion of people with disabilities.</p> <p>But the experiences of people with disability show Australia is a very long way from achieving this. There are the stories from people with disability who <a href="https://www.abc.net.au/news/2023-06-25/taylor-swift-concert-disability-access-concerns/102520088">can’t enjoy events</a> or <a href="https://www.abc.net.au/news/2023-03-09/harry-styles-concert-disability-tickets-consumer-rights/102060698">venues</a>. And researchers say even <a href="https://www.unsw.edu.au/arts-design-architecture/our-research/research-impact/case-studies/are-our-accessible-bathrooms-inaccessible-to-people-in-wheelchairs">accessible bathrooms are not usable</a> for half the people with disability.</p> <p>What can be called an accessible building or home? And should standards be improved?</p> <h2>What is accessibility?</h2> <p>The <a href="https://www.ohchr.org/en/instruments-mechanisms/instruments/convention-rights-persons-disabilities">Convention on the Rights of Persons with Disability</a> includes the right to accessibility. Australia’s 1992 <a href="https://humanrights.gov.au/our-work/disability-rights/frequently-asked-questions-access-premises">Disability Discrimination Act</a> includes premises standards to ensure people with disability have “dignified, equitable, cost-effective and reasonably achievable access to buildings, facilities and services”.</p> <p>However, a building is exempt if the owners can demonstrate modifying a building would cause them “unjustifiable hardship”. The burden of making a complaint about an inaccessible building falls on people with disability and the act also does not apply to private homes.</p> <p>Although experts follow different definitions of accessibility, they generally include some key principles:</p> <ul> <li> <p>easy entry and exit into a building</p> </li> <li> <p>easy navigation and functionality in and around the building</p> </li> <li> <p>potential for easy adaptation in response to changing needs of occupants.</p> </li> </ul> <p>An accessible building is one where people of all abilities are able move and carry out activities independently, safely, in comfort and with dignity.</p> <p>For people with disabilities <a href="https://disability.unimelb.edu.au/__data/assets/pdf_file/0010/3969109/Accessible-Housing-Research-Report-22-October-2020.pdf">many buildings are inaccessible</a>. In these buildings, basic everyday activities such as taking a shower or preparing breakfast becomes difficult, tiring, uncomfortable and sometimes dangerous.</p> <p>Some people have been <a href="https://disability.unimelb.edu.au/__data/assets/pdf_file/0010/3969109/Accessible-Housing-Research-Report-22-October-2020.pdf">injured</a> repeatedly in inaccessible homes, for example falling down a staircase. Such injuries may compound their disability. Many people with disabilities worry that if they’re injured at home, they will be forced to move permanently into a nursing home.</p> <p><a href="https://www.sciencedirect.com/science/article/pii/S0016718523001525">Studies</a> have found living in inaccessible homes severely harms the dignity, independence, social inclusion, employment, health and wellbeing of people with disabilities.</p> <p>People become more reliant on family members for support, putting strain on their relationships. Difficulty getting in and out of the house for social activities worsens social isolation. A sense of fatigue also reduces the motivation and capacity to work.</p> <h2>Access through the front door</h2> <p>Dignity is a crucial aspect of accessibility but it is often forgotten. For example, many buildings’ front entry has stairs that make it inaccessible for wheelchair users. There may be an accessible ramp entry in the back of the building. The building is then considered accessible, since wheelchair users can enter and exit. But such a “backdoor treatment” can be experienced as an indignity and discrimination.</p> <p>Accessible toilets are sometimes used for <a href="https://www.sbs.com.au/news/article/most-public-toilets-inaccessible-to-people-with-disabilities/adsx7cnr8">storage, locked or out of order</a>. Again, although the design meets accessibility standards, in practice the building is inaccessible because of poor management.</p> <p>And accessibility is not exclusively about physical disabilities and physical barriers.</p> <p>People with cognitive disabilities, for example, might struggle to find their way in a building if way-finding signs are difficult to understand. <a href="https://theconversation.com/for-people-with-communication-disability-complaining-about-their-treatment-isnt-so-simple-214717">Communication accessibility</a> in building is achieved when the information needed to navigate and use the building is understood by everyone, no matter how they communicate.</p> <h2>Silver, gold and platinum standards</h2> <p>There are different levels of accessibility. In Australia, housing accessibility is most often assessed according to <a href="https://livablehousingaustralia.org.au/wp-content/uploads/2021/02/SLLHA_GuidelinesJuly2017FINAL4.pdf">Livable Housing Australia</a>’s (LHA) three standards of silver, gold and platinum. Silver-level homes have minimal accessibility features, but are designed in a way that enables easy home modifications over time.</p> <p>The silver standard of accessibility requires seven features:</p> <p>• a step-free path of travel from the street or parking area</p> <p>• at least one step-free entrance</p> <p>• internal doors and corridors that allow comfortable movement, including for people using wheelchairs</p> <p>• a toilet on the entry level with easy access</p> <p>• a bathroom with a hobless shower recess, so there isn’t a step-over barrier to entry</p> <p>• reinforced walls around the toilet, shower and bath. These allow installation of grabrails later if needed</p> <p>• stairways designed to reduce the risk of injury and also enable future adaptation.</p> <p>Gold-level homes have additional accessibility features. Platinum homes are designed for people with higher mobility needs and to allow ageing at home.</p> <h2>A patchwork of standards and what the NDIS review says</h2> <p>In 2021 Australian housing ministers <a href="https://www.industry.gov.au/news/building-ministers-meeting-communique-april-2021">agreed for the first time</a> to introduce minimum accessibility standards in the National Construction Code. It followed decades of campaigning by activist groups such as the <a href="https://anuhd.org/">Australian Network for Universal Housing Design</a>, <a href="https://riaustralia.org/">Rights and Inclusion Australia</a> and the <a href="https://www.summerfoundation.org.au/">Summer Foundation</a>.</p> <p>The code requires all new homes be built to silver standards. It does not apply to existing homes and exemptions will apply for some newly built homes because of site restrictions.</p> <p>When the code was introduced, New South Wales and Western Australia announced they would not adopt the new code. Both the NDIS review and the disability royal commission recommended all states and territories <a href="https://disability.royalcommission.gov.au/system/files/2023-09/Final%20Report%20-%20Volume%207%2C%20Inclusive%20education%2C%20employment%20and%20housing%20-%20Part%20C.pdf">immediately adopt</a> the code’s new accessibility standards.</p> <p>A consistent application of the code’s new standards across Australia is a good start. But the code provides only the minimum standard of accessibility. To make buildings and homes truly accessible, we need to improve education on accessibility for designers, operators and consumers.</p> <h2>An urgent national priority</h2> <p>With Australia’s ageing population, most people will experience disability – or have a household member with disability – at some point.</p> <p>Accessible homes and buildings can reduce pressure on the health system and improve quality of life. A consistent national construction code is just the first step urgently needed to improve building accessibility and inclusion so people with disability have autonomy and flourish.<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;" src="https://counter.theconversation.com/content/217278/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/ilan-wiesel-303040">Ilan Wiesel</a>, Associate Professor in Urban Geography, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> and <a href="https://theconversation.com/profiles/rebecca-bentley-173502">Rebecca Bentley</a>, Professor of Social Epidemiology and Director of the Centre of Research Excellence in Healthy Housing at the Melbourne School of Population and Global Health, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Caring

Placeholder Content Image

Transgress to impress: why do people tag buildings – and are there any solutions?

<p><em><a href="https://theconversation.com/profiles/flavia-marcello-403040">Flavia Marcello</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>In 1985 photographer Rennie Ellis <a href="https://trove.nla.gov.au/work/8707788">defined graffiti</a> as “the result of someone’s urge to say something – to comment, inform, entertain, persuade, offend or simply to confirm his or her own existence here on earth”. Since the mid-1980s, graffiti has crossed from vandalism to an accepted form of art practice through large murals or “pieces” and stencil art aimed at informing, entertaining and persuading us.</p> <p>But these are outnumbered by the tags you see everywhere. These stylised icon-type signatures define a hand style and confirm their author’s existence on Earth. These, for many of us, remain an eyesore. If you walk through an urban environment filled with tags, you may feel less safe. Heavily tagged areas can suggest the area is not cared for or surveilled.</p> <p>So why are Australian cities so full of tags? The problem is, the main solution proven to work is expensive. When tags go up, paint over them – and keep doing it. While anti-graffiti paint exists, it’s not widely used at present.</p> <h2>Why do people tag?</h2> <p>Graffiti in urban centres is often tied to the world-wide proliferation of hip-hop culture. Along with DJing, rapping and breakdancing, “Graf” or “writing” is considered one of its <a href="https://www.britannica.com/art/hip-hop">four pillars</a>.</p> <p>Posturing (or showing off) is a big part of tagging. When you see a tag on a freeway overpass or seemingly inaccessible building parapet, it’s not only confirming the tagger’s existence, it’s bragging. See how high I climbed! See what crazy risks I took!</p> <p>As one tagger in Sydney’s outer south-western suburb of Campbelltown <a href="https://www.aic.gov.au/sites/default/files/2020-05/vandalism-graffiti-state-rail-authority-nsw.pdf">told researchers</a> in the 1980s:</p> <blockquote> <p>If you get on a train and see your name and know you’ve been here before that’s real good. Like, I was here. Or you see your mate’s name and you can say, hey, I know him […] It’s really good if you can get your name up in a difficult place where nobody else has. Other kids look at that and think, great!</p> </blockquote> <p>So why do people tag?</p> <ul> <li> <p>it boosts self-esteem and a sense of belonging to a social network, particularly for teens experiencing alienation at school</p> </li> <li> <p>it demonstrates bravado. Risky places have the added advantages of being both highly visible and harder to remove</p> </li> <li> <p>it gives graf artists practice for bigger pieces. You have to work quickly and accurately, especially in precarious positions where you could get caught at any moment.</p> </li> </ul> <p>While cities like Melbourne <a href="https://www.timeout.com/melbourne/art/where-to-find-the-best-street-art-in-melbourne">have embraced</a> larger murals and pieces as street art – even making them a tourist attraction – tagging isn’t regarded the same way.</p> <p>So why do non-taggers hate it? On a broader level, tagging can signify a sense of social degradation which makes people feel less safe.</p> <p>There’s no clear link between <a href="https://www.aic.gov.au/publications/rip/rip6">more graffiti and more crime</a>. Even so, the public perception is that tagging is a sign warning of the presence of <a href="https://www.aic.gov.au/sites/default/files/2020-05/vandalism-graffiti-state-rail-authority-nsw.pdf">disaffected and potentially violent</a> people in gangs.</p> <p>Asked to picture a tagger and you will most likely come up with a stock photo stereotype: a male teenager in a hoodie from a seedy area. But you would not be completely right. It is true just under half (46%) of graffiti damage and related offences are committed by 14 to 16 year old males, but the largest percentage of offenders actually come from <a href="https://www.goodbyegraffiti.wa.gov.au/Schools/Facts-for-Students/Who-are-the-most-likely-offenders-of-graffiti">middle- to high-income families</a>.</p> <p>So what tools do we have to manage it?</p> <h2>Punishment</h2> <p>It’s perfectly legal to commission a graf artist to paint a wall of a building you own. Many people do this to avoid a street-facing wall being tagged. For it to be illegal, tagging or graffiti has to be done without the owner’s permission.</p> <p>Since the majority of taggers are under 18, if they’re caught, punishment will usually include a caution, fines (presumably paid by bemused but cashed up parents) and cleaning off tags.</p> <p>But punitive measures only go so far because the appeal of graffiti is the transgression. Other measures include keeping spray paint locked away or not for sale to under 18s as well as zero-tolerance rapid removal. This can work for a while, but taggers know their tags are temporary. It’s a constant game of cat and mouse a committed tagger will eventually win.</p> <h2>Technical solutions</h2> <p>If you’ve walked past workers scrubbing or pressure washing tags off walls, you may have wondered why there are no coatings which don’t let paint stick.</p> <p>These actually <a href="https://www.ipcm.it/en/article/anti-graffiti-paints-what-are-they-and-how-they-work.aspx">do exist</a>, and can work well. When in place, you can remove graffiti with a solvent rather than having to repaint. But they’re not widely used.</p> <p>Unless paints such as <a href="https://interestingengineering.com/innovation/7-inventions-from-mexico-that-would-go-on-to-change-the-world">Deletum 3000</a> are used everywhere this approach is unlikely to be effective.</p> <h2>Prevention</h2> <p>The problem with punitive and technical measures is the limited reach. The vast majority of unwanted graffiti <a href="https://www.aic.gov.au/publications/rip/rip6">goes unreported</a>. That’s why prevention is becoming more popular.</p> <p>How do you prevent tagging? By making it easier to report. By setting aside areas for taggers and graf artists. By commissioning pieces to deter graffers from illegal modes. And by talking directly to taggers about strategies. But these behaviour change efforts take time.</p> <p>People who hate tagging often believe taggers are motivated by negative emotions such as <a href="https://www.aic.gov.au/publications/rip/rip6">boredom and rebelliousness</a>. For them it’s vandalism, a criminal act associated with gangs, petty crime, broken windows and a less attractive environment to live in.</p> <p>But the truth is, taggers are often motivated by positive emotions. Tagging, for them, brings pride, pleasure, enjoyment and community. That’s why behaviour change approaches can be hard.</p> <h2>So what’s the best way forward?</h2> <p>In the 1990s, many cities declared war on skateboarders, using punishment and installing metal stoppers on well-skated urban areas. But the real solution was simpler: create skate parks.</p> <p>For taggers, the answer may be similar. Give them spaces such as little-used alleyways to practise their art. And for the rest of us, the solution may be to look at tags with different eyes. Not as a sign of crime and the collapse of civilisation, but as a need for validation, for transgression, for community and all the other things you probably wanted when you were a teenager.<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;" src="https://counter.theconversation.com/content/205492/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/flavia-marcello-403040">Flavia Marcello</a>, Professor of Design History, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Am I too old to build muscle? What science says about sarcopenia and building strength later in life

Toxic pollutants can build up inside our homes. Here are 8 ways to reduce the risks

<p>We know everything in our homes gathers dust. What you probably don’t know is whether there are toxic contaminants in your house dust, and where these might come from. </p> <p>Our <a href="https://doi.org/10.1016/j.envres.2022.115173">newly published research</a> found most of the dust inside homes came from outside and contains potentially toxic trace metals such as lead, arsenic and chromium. </p> <p>Worryingly, we found some contaminants can accumulate at higher concentrations inside homes than outside. This happened in homes with certain characteristics: older properties, metal construction materials enriched in zinc, recent renovations and deteriorating paint. </p> <p>Fortunately, you can take some simple steps to reduce your exposure, which we explain later.</p> <h2>What’s in house dust?</h2> <p>Our study explored the connected sources, pathways and potentially harmful exposures to trace metals at homes across Sydney. We collected and analysed 383 samples from nearby road dust (51 samples) and garden soil (166), as well as indoor dust (166).</p> <p>We found the dust in homes comes from a range of sources including outdoor environments and soil, skin, cleaning products, pet hair and cooking particles.<br />Nearly 60% of dust particles inside the homes originated from their immediate outdoor environment – it was <a href="https://theconversation.com/wearing-shoes-in-the-house-is-just-plain-gross-the-verdict-from-scientists-who-study-indoor-contaminants-177542">dirt from outside</a>!

These included <a href="https://theconversation.com/microplastics-are-common-in-homes-across-29-countries-new-research-shows-whos-most-at-risk-189051">fibres from clothes, carpets and furnishings</a>, cleaning products, skin and hair.</p> <p>Some dust sources can carry a cocktail of potentially harmful contaminants including:</p> <ul> <li> <p><a href="https://doi.org/10.1016/j.envpol.2021.117064">microplastics</a></p> </li> <li> <p><a href="https://doi.org/10.1016/j.envres.2014.10.009">persistent organic pollutants</a></p> </li> <li> <p><a href="https://doi.org/10.1016/j.scitotenv.2019.05.463">perfluorinated chemicals</a> (PFAS)</p> </li> <li> <p><a href="https://doi.org/10.1016/j.envpol.2021.117593">trace metals</a></p> </li> <li> <p><a href="https://doi.org/10.3389/fenvs.2021.754657">bacterial communities</a></p> </li> <li> <p><a href="https://doi.org/10.1016/j.envint.2021.106501">antimicrobial resistance genes</a>. </p> </li> </ul> <p>The nature of the risk is related to how much of the contaminant you’re exposed to and for how long. The risks are greatest in children under the age of five. This is because they are small, closer to the floor and have frequent hand-mouth contact, which increases ingestion of contaminants.</p> <h2>How do contaminants build up in homes?</h2> <p>Industrial activity has left a marked legacy of contaminants in many city neighbourhoods. We analysed road dust, garden soil and vacuum dust samples from 166 homes in Sydney to see how this risk translated to inside homes. We used high-magnification microscopy and <a href="https://www.climate-policy-watcher.org/earth-sciences/lead-isotopes-as-tools-for-source-identification.html">lead isotopic ratios</a> to understand trace metal composition in the samples. </p> <p>On average, concentrations of trace metals arsenic, chromium, copper, manganese, lead and zinc were all higher inside homes than outside. This means homes are not only “accumulators” of trace metal contaminants but also important sources of a significant proportion of harmful contaminants that we can be exposed to. </p> <p>The lead isotopic ratios, or the lead “fingerprints”, of each home and its garden soil matched. This confirms the soil is the main source of lead inside homes. </p> <p>Most of this lead is the result of the pre-1970s use of high concentrations of lead in <a href="https://www.dcceew.gov.au/environment/protection/chemicals-management/lead/lead-in-house-paint">paints</a> and <a href="http://dx.doi.org/10.1016/j.apgeochem.2017.02.007">petrol</a>, which contaminated many garden soils. Even <a href="https://theconversation.com/why-lead-is-dangerous-and-the-damage-it-does-116506">low levels of lead exposure</a> can be harmful. Lead levels in some <a href="https://theconversation.com/elevated-lead-levels-in-sydney-back-yards-heres-what-you-can-do-68499">Sydney backyards</a> pose a risk for <a href="https://doi.org/10.1016/j.dib.2021.107151">urban veggie growers</a> and <a href="https://theconversation.com/backyard-hens-eggs-contain-40-times-more-lead-on-averagethan-shop-eggs-research-finds-187442">backyard chickens and their eggs</a>.</p> <p>High-magnification images of house dust showed mineral particles that have been blown in or tracked in on shoes. The rest of the dust was elongated fibres and hair from indoor sources.</p> <h2>Which homes are most at risk?</h2> <p>We also collected information about each house, relevant activities and renovations at the property. We found house age, proximity to the city centre and renovations had the greatest influence on levels of lead and other trace metals in the home. </p> <p>All homes more than 50 years old had higher concentrations of arsenic, copper, lead and zinc in their garden soil and house dust. They are typically <a href="https://iupui-earth-science.shinyapps.io/MME_Sydney/">located closer to city centres</a>, where early industrial activity has contaminated soils. </p> <p>As older homes in former industrial areas are renovated, trace metal loads in these homes and gardens can increase. Walls and ceilings contain decades of dust. Old paint buried under more recent layers can also be released, causing <a href="https://www.abc.net.au/radionational/programs/backgroundbriefing/3983094">lead exposure risks</a>. </p> <p>It is critical that home renovators take appropriate remediation steps or <a href="https://painters.edu.au/Training-Courses/CPCCPD3031-Work-safely-with-lead-painted-surfaces-in-the-painting-industry.htm">employ a qualified paint professional</a> so lead dust isn’t spread across the area.</p> <h2>8 ways to reduce your risk</h2> <p>We spend about <a href="https://escholarship.org/uc/item/1zg3q68x#main">70% of our time at home</a>, which the pandemic has increased.

Building and construction emissions and energy use reaches record levels

<p>Despite improvements in energy efficiency, greenhouse pollution levels from the building and construction sector reached an all-time high in 2021.</p> <p>A new report on the building and construction sector by the United Nations Environment Programme released for COP27 found energy demand in buildings – for heating, cooling, lighting and equipment – increased by 4% from 2020 levels. As a result, the sector’s emissions increased 5% compared to 2020.</p> <p>While the increase partly reflects a re-bound in building and construction activities after the pandemic, energy and emissions levels were also above 2019 levels.</p> <p>This is significant because the sector accounts for around a third of total energy demand, the report says.</p> <p>The UN Secretary General Antonio Guterres told the opening forum of COP27 that the future of the planet is in our hands. “…and the clock is ticking. We are in the fight of our lives. And we are losing. Greenhouse gas emissions keep growing. Global temperatures keep rising. And our planet is fast approaching tipping points that will make climate chaos irreversible.</p> <p>“We are on a highway to climate hell with our foot still on the accelerator. “</p> <p>With the release of the report, UNEP executive director, Inger Andersen added: “If we do not rapidly cut emissions in line with the Paris Agreement, we will be in deeper trouble.”</p> <p>The UNEP report argues investments in energy efficiency must be sustained in the face of growing crises – such as the war in Ukraine and rising energy and living costs – to help with reducing energy demand, avoiding greenhouse gas pollution and reducing energy cost volatility.</p> <p>“The solution may lie in governments directing relief towards low and zero-carbon building investment activities through financial and non-financial incentives,” Andersen says.</p> <p>Also critical to reducing the sector’s emissions are including buildings in climate pledges under the Paris Agreement – known as Nationally Determined Contributions – and mandatory building energy codes.</p> <p>The report’s recommendations include: building coalitions of stakeholders in support of sustainable buildings, governments introducing mandatory building energy codes and government policies, increasing investment in energy efficiency and commitments from industry.</p> <p><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=222598&amp;title=Building+and+construction+emissions+and+energy+use+reaches+record+levels" width="1" height="1" /></p> <div id="contributors"> <p><em><a href="https://cosmosmagazine.com/earth/building-emissions-reach-record-levels/" target="_blank" rel="noopener">This article</a> was originally published on Cosmos Magazine and was written by Petra Stock. </em></p> <p><em>Image: Getty Images</em></p> </div>

<p dir="ltr">A professional cleaner has shared six things to avoid when building a house in order to make your home easier to clean. </p> <p dir="ltr">Kacie from The Big Clean Co in Melbourne shared the tips in a TikTok video which racked up over 600,000 views in less than 14 hours. </p> <p dir="ltr">She recommends choosing alternative style solutions rather than opting for blinds with small slats, freestanding bathtubs, square sinks and black tapware. </p> <p dir="ltr">Kacie said that blinds with smaller slats accumulate much more dust, making it a long task to individually clean each one. </p> <p dir="ltr">She also said that while free-standing bathtubs are a chic and modern styling option, it's important to avoid placing them right beside the wall because it becomes difficult to clean the tight gap. </p> <p dir="ltr">“You need to be able to clean in there,” she said.  </p> <p dir="ltr">Kacie recommends opting for a round or oval sink in kitchens and bathrooms, as corners of square sinks are “so annoying to clean”. </p> <p dir="ltr">She also suggested not to install “sensitive” black tapware unless you are “really sure it's durable” because over time the black coating fades, exposing the bronze brass underneath.</p> <p dir="ltr">When choosing kitchen cabinetry, Kacie recommends minimising the space between the cupboards and ceiling as she said “it's just a shelf to catch grease on”.</p> <p dir="ltr">Her video was flooded with praise in the comments, with one person writing, “Fellow cleaner here! COMPLETELY AGREE!”</p> <p dir="ltr"><em>Image credits: TikTok</em></p>

Top tips to find the perfect flooring

<p dir="ltr">From wood or floating floors to tiles or carpet, choosing flooring that is both functional and builds on the feel and liveability of your entire home can be a tricky task.</p> <p dir="ltr">For interior design enthusiast and Carpet Court Style Collaborator, Emily Osmond, the task of finding the perfect flooring is a familiar one that she says was one of the biggest decisions she had to make while building her first home .</p> <p dir="ltr">“Hard or soft, flooring is one of the most important design selections you will make for your new build - it plays a huge role in creating mood, texture, colour and flow throughout the home,” she says.</p> <p dir="ltr">“When it came to designing the interior, we started from the ground and worked our way up, knowing that whatever material and colourway we decided to include on the floors would form the foundation of our entire interior style.”</p> <p><span id="docs-internal-guid-cb0288f3-7fff-9ecc-1922-5fac5b1ab145"></span></p> <p dir="ltr">But you don’t just have to consider flooring if you’re starting from scratch. Whether you’re planning some major renovations or just want to update the flooring in key spaces, Emily says the best option will come down to three key factors: material, lifestyle, and the space’s functionality.</p> <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/p/CckYQaEPYKu/?utm_source=ig_embed&amp;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/CckYQaEPYKu/?utm_source=ig_embed&amp;utm_campaign=loading" target="_blank" rel="noopener">A post shared by EMILY OSMOND | Business Coach &amp; Speaker (@emilyosmond)</a></p> </div> </blockquote> <p dir="ltr">“I wanted our bedrooms and retreat to feel cosy and like a place to unwind, so the softness of carpet was perfect for these spaces,” Emily says.</p> <p dir="ltr">“When it came to our entrance, knowing this would be a high traffic area meant that engineered timber was the best option. To emphasise how large and open the area is, we continued with this flooring seamlessly from the entrance to the kitchen, living and dining space, drawing the eye down the hallway.”</p> <p dir="ltr">Flooring, Emily stresses, acts as the basis for your entire home, and choosing an option that suits the space and that you’re happy with will save you the work of changing it later.</p> <p dir="ltr">“Paint can be easily updated, or cabinetry colours tweaked, but flooring is the base on which your whole home’s style is built upon and shouldn’t be overlooked,” she says.</p> <p dir="ltr">To help you pick the flooring that suits your needs, Emily has shared these three tips.</p> <p dir="ltr"><strong>Budget</strong> - Building or renovating your home often sees you work within quite a tight budget, but flooring and carpet is a worthwhile item to invest in. Since it will be walked on every day, avoid skimping so you can pick high quality options.</p> <p dir="ltr"><strong>Realise your vision</strong> - Making a mood board for her project helped Emily capture the overall aesthetic and feel of the home. Plus, having a physical version of your plan - whether as a mood board or model - can serve as a reference point you can come back to as you need.</p> <p dir="ltr"><strong>Be confident</strong> - Though everyone’s taste differs, be confident in the decisions you make since only you known the vision you have for your home (and you will be the person living there every day).</p> <p dir="ltr"><span id="docs-internal-guid-7cf373e2-7fff-0da8-ef90-9dae0e3e95ef"></span></p> <p dir="ltr"><em>Image: @emilyosmond (Instagram)</em></p>

Digital inequality: why can I enter your building – but your website shows me the door?

<p>When people hear the term “accessibility” in the context of disability, most will see images of ramps, automatic doors, elevators, or tactile paving (textured ground which helps vision impaired people navigate public spaces). These are physical examples of inclusive practice that most people understand.</p> <p>You may even use these features yourself, for convenience, as you go about your day. However, such efforts to create an inclusive physical world aren’t being translated into designing the digital world.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/463211/original/file-20220516-25-nl8hd8.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/463211/original/file-20220516-25-nl8hd8.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/463211/original/file-20220516-25-nl8hd8.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=400&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/463211/original/file-20220516-25-nl8hd8.jpeg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=400&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/463211/original/file-20220516-25-nl8hd8.jpeg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=400&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/463211/original/file-20220516-25-nl8hd8.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=503&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/463211/original/file-20220516-25-nl8hd8.jpeg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=503&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/463211/original/file-20220516-25-nl8hd8.jpeg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=503&amp;fit=crop&amp;dpr=3 2262w" alt="A large wheelchair sign is visible to the left of a wheelchair ramp." /></a><figcaption><em><span class="caption">New buildings are required to comply with a range of physical access requirements, which may include tactile paving (seen in yellow).</span> <span class="attribution"><span class="source">Shutterstock</span></span></em></figcaption></figure> <p><strong>Accessibility fails</strong></p> <p>Digital accessibility refers to the way people with a lived experience of disability interact with the cyber world.</p> <p>One example comes from an author of this article, <a href="https://www.abc.net.au/news/science/2019-07-13/dark-patterns-online-captcha-accessibility-disability-community/11301054" target="_blank" rel="noopener">Scott</a>, who is legally blind.

The World Wide Web Consortium’s <a href="https://www.w3.org/TR/WCAG21/" target="_blank" rel="noopener">Web Content Accessibility Guidelines</a> (WCAG) standard has been widely adopted across the globe. It’s universally available, and is a requirement for all Australian public-facing government websites.</p> <p>It guides website and app developers on how to use web languages (such as HTML and CSS) in ways that enable end users who rely on assistive technologies. There are no specialist technologies or techniques required to make websites or apps accessible. All that’s needed is an adherence to good practice.</p> <p>Unfortunately, WCAG is rarely treated as an <a href="https://www.rev.com/blog/web-accessibility-laws-australia-new-zealand" target="_blank" rel="noopener">enforceable standard</a>. All too often, adherence to WCAG requirements in Australia is reduced to a box-ticking exercise.</p> <p>Our academic work and experience liaising with a range of vendors has revealed that even where specific accessibility requirements are stated, many vendors will tick “yes” regardless of their knowledge of accessibility principles, or their ability to deliver against the standards.</p> <p>In cases where vendors do genuinely work towards WCAG compliance, they often rely on automated testing (via online tools), rather than human <a href="https://zoonou.com/resources/blog/why-automated-accessibility-testing-tools-are-not-enough/" target="_blank" rel="noopener">testing</a>.

While the coding of each element of a website might be WCAG compliant, the sum of all the parts may not be.</p> <p>In 2016, the Australian government adopted <a href="https://www.accessibility.org.au/policy-and-research/australian-policy/" target="_blank" rel="noopener">standard EN 301549</a> (a direct implementation of an existing European standard).

The variation advantage: how to master tennis, learn a language, or build better AI

<p>Want to become a better tennis player? If you repeatedly practise serving to the same spot, you’ll master serving to that <em>exact</em> location, if conditions remain similar. Practising your serve to a variety of locations will take much longer to master, but in the end you’ll be a better tennis player, and much more capable of facing a fierce opponent.</p> <p>The reason why is all about variability: the more we’re exposed to, the better our neural networks are able to generalise and calculate which information is important to the task, and what is not. This also helps us learn and make decisions in new contexts.</p> <p><strong>From fox to hounds</strong></p> <p>This generalisation principle can be applied to many things, including learning languages or recognising dog breeds. For example, an infant will have difficulty learning what a ‘dog’ is if they are only exposed to chihuahuas instead of many dog breeds (chihuahuas, beagles, bulldogs etc.), which show the real variation of <em>Canis lupus familiaris</em>. Including information about what is <em>not</em> in the dog category – for example foxes – also helps us build generalisations, which helps us to eliminate irrelevant information.</p> <p>“Learning from less variable input is often fast, but may fail to generalise to new stimuli,” says Dr Limor Raviv, the senior investigator from the Max Planck Institute (Germany). “But these important insights have not been unified into a single theoretical framework, which has obscured the bigger picture.”</p> <p>To better understand the patterns behind this generalisation framework, and how variability effects the human learning process and that of computers, Raviv’s research team explored over 150 studies on variability and generalisation across the fields of computer science, linguistics, motor learning, visual perception and formal education.</p> <p><strong>Wax on, wax off</strong></p> <p>The researchers found that there are at least four kinds of variability, including:</p> <ul> <li><strong>Numerosity</strong> (set size), which is the number of different examples; such as the number of locations on the tennis court a served ball could land</li> <li><strong>Heterogeneity</strong> (differences between examples); serving to the same spot versus serving to different spots</li> <li><strong>Situational</strong> (context) diversity; facing the same opponent on the same court or a different component on a different court</li> <li><strong>Scheduling</strong> (interleaving, spacing); how frequently you practice, and in what order do you practice components of a task</li> </ul> <p>“These four kinds of variability have never been directly compared—which means that we currently don’t know which is most effective for learning,” says Raviv.</p> <div class="newsletter-box"> <div id="wpcf7-f6-p191362-o1" class="wpcf7" dir="ltr" lang="en-US" role="form"> <form class="wpcf7-form mailchimp-ext-0.5.61 init" action="/people/behaviour/the-variation-advantage-how-to-master-tennis-learn-a-language-or-build-better-ai/#wpcf7-f6-p191362-o1" method="post" novalidate="novalidate" data-status="init"> <p style="display: none !important;"><span class="wpcf7-form-control-wrap referer-page"><input class="wpcf7-form-control wpcf7-text referer-page" name="referer-page" type="hidden" value="https://cosmosmagazine.com/technology/" data-value="https://cosmosmagazine.com/technology/" aria-invalid="false" /></span></p> <p><!-- Chimpmail extension by Renzo Johnson --></form> </div> </div> <p>According to the ‘Mr Miyagi principle’, inspired by the 1984 movie <em>The Karate Kid</em>, practising unrelated skills – such as waxing cars or painting fences – might actually benefit the learning of other skills: in the movie’s case, martial arts.</p> <p><strong>Lemon or lime?</strong></p> <p>So why does including variability in training slow things down? One theory is that there are always exceptions to the rules, which makes learning and generalising harder.</p> <p>For example, while colour is important for distinguishing lemons from limes, it wouldn’t be helpful for telling cars and trucks apart. Then there are atypical examples – such as a chihuahua that doesn’t look like a dog, and a fox that does, but isn’t.</p> <p>So as well as learning a rule to make neural shortcuts, we also have to learn exceptions to these rules, which makes learning slower and more complicated. This means that when training is variable, learners have to actively reconstruct memories, which takes more effort.</p> <p><strong>Putting a face to a name</strong></p> <p>So how do we train ourselves and computers to recognise faces? The illustration below is an example of variations of a fox for machine learning. Providing several variations – including image rotation, colour and partial masking – improves the machine’s ability to generalise (in this case, to identify a fox). This data augmentation technique is an effective way of expanding the amount of available data by providing variations of the same data point, but it slows down the speed of learning.</p> <p>Humans are the same: the more variables we’re presented with, the harder it is for us to learn – but eventually it pays off in a greater ability to generalise knowledge in new contexts.</p> <p>“Understanding the impact of variability is important for literally every aspect of our daily life. Beyond affecting the way we learn language, motor skills, and categories, it even has an impact on our social lives.” explains Raviv. “For example, face recognition is affected by whether people grew up in a small community (fewer than 1000 people) or in larger community (over 30,000 people). Exposure to fewer faces during childhood is associated with diminished face memory.”</p> <p>The learning message for both humans and AI is clear: variation is key. Switch up your tennis serve, play with lots of different dogs, and practice language with a variety of speakers. Your brain (or algorithm) will thank you for it… eventually.</p> <p><!-- Start of tracking content syndication.

Man selling US$60 million castle so he can build another one

<p>The fairytale castle that looks straight out of the opening credits to any Disney movie - a custom-built castle in northeast Connecticut, US.</p> <p>After originally being put on the market for US$35 million in November 2021, this incredible nine-bedroom masterpiece has been freshly re-listed .... for almost DOUBLE, at US$60 million.</p> <p>The reason for the price increase? Its owner, Chris Mark, needs funding – a LOT more funding – to move on and begin construction on yet another fairytale castle.</p> <p>“We had a couple of serious inquiries,” agent John Pizzi of Randall Realtors told The Post of the fairytale property’s luck since November. “The owner is relocating out of state and he thought he would build another castle, and in talking to architects and engineers, he realised he would need in the ballpark of US$60 million to construct another mediaeval-energy mansion."</p> <p>Mark completed the current castle in 2010, but is ready to move on from it now that his daughters have graduated high school. </p> <p>Mark — who is the descendant of a Chicago steel tycoon – was very hands-on and passionate in having the castle built. He went as far as buying a boat manufacturer to more easily acquire materials needed, and imported the labor of Polish, Czech and Russian craftsmen to construct it.</p> <p>“You would think it was something from the 1400s or 1500s, but it’s less than 20 years old,” Pizzi noted of the high quality result of Mark’s energies.</p> <p>“Fit for the contemporary king, this architectural wonder is accessible via two different stone bridges,” reads the site dedicated to the 10-bathroom home. “Upon crossing between towering turrets, the natural stone pathways guide visitors over a deep moat that surrounds the entire estate.”</p> <p>There are modern conveniences including central air, an elevator, radiant flooring, a pool, a dock and a garage, as well as gothic luxuries, such as 12 fireplaces, 126-foot-high turrets, an entry hall, a 30-acre pond, stained glass and 25 types of hardwood flooring. There’s also a raised stage auditorium, a guest apartment, a recording studio and 400 acres including a moat.</p> <p><em>Images: Tyra Pacheco</em></p> <p><em> </em></p>

Arctic heatwaves building in intensity

<div> <p>Ocean heatwaves in the Arctic are increasing in power and frequency, quite probably at a greater rate than in other oceans, according to new research.</p> <p>Marine heatwaves are events in which water temperatures rise well above normal and remain there for days, weeks, or even months. At lower latitudes, they can damage corals and force fish and marine mammals to temporarily move away in pursuit of food and cooler water. It’s an effect that has been compared to that of decades of climate change impact, but all at once.</p> <p>In the Arctic, the effect isn’t as well documented, but with climate change proceeding more dramatically there than at lower latitudes, a team led by Boyin Huang of the US National Oceanic and Atmospheric Administration’s National Centers for Environmental Information in Asheville, North Carolina, examined nearly four decades of US, European and Japanese satellite data to find out how climate change is altering the strength and frequency of these heatwaves.</p> <p>Huang presented his study this week at the 2022 Ocean Sciences Meeting, which for the first time was conducted entirely virtually. (Organisers had already said two years ago that they wanted to include a virtual component this year, in order to save resources and spare the climate, even before COVID-19 forced them to do so.)</p> <p>The study examined sea-surface temperatures,  air temperatures, ice coverage and the extent of cloud coverage, all of which can increase the likelihood of heatwaves. </p> <p>On average, Huang said, the Arctic sees one to two such heatwaves per summer. But over his study period, from 1982 to 2020, they were getting longer, stronger and extending ever deeper into autumn.</p> <p>In the early years, Huang says, the heatwaves were confined to a short season from late July to early August. Since then, however, that season has dramatically expanded, ending in mid-August or even through to the end of September.</p> <p>Other scientists are studying different types of changes in the Arctic that may (or may not) be related. For example, Michael Karcher, a senior researcher at the Alfred Wegener Institute for Polar and Marine Research in Bremerhaven, Germany, says scientists realised 25 years ago that plumes of iodine-129 (a rare, radioactive isotope of iodine) from nuclear fuel reprocessing plants in France and the UK can be used as a tracer of the flow of North Atlantic seawater into and around the Artic Ocean.</p> <p>What this has revealed, Karcher told the Ocean Sciences Meeting, is that there has been a change in the circulation pattern in the Arctic Ocean that has allowed relatively warm Atlantic Ocean water to penetrate further toward Alaska, reducing the spread of cooler Pacific water (which is not contaminated with iodine-129, and is therefore easy to distinguish).</p> <p>Karcher and Huang were unable to say whether this was contributing to Arctic heatwaves. In theory, the warmer water from the Atlantic should have some impact as it travels beneath the pack ice.</p> <p>“But how much it interacts with ice is the open question,” says Huang. “Our speculation is that atmospheric forcing [ie top-down heat] is the more important contributor.”</p> <p>The bottom line, however, is clear. Arctic waters are changing, and quickly.</p> <p>Huang’s research was published late last year in Geophysical Research Letters.</p> <p>This article originally appeared on <a href="https://cosmosmagazine.com/earth/oceans/ocean-arctic-heatwaves/" target="_blank" rel="noopener">cosmosmagazine.com</a> and was written by Richard A Lovett. </div> <div> </div> <div><em>Image: Shutterstock</em></div>
