‘A woman is not a baby-making machine’: a brief history of South Korea’s 4B movement – and why it’s making waves in America

<a href="https://theconversation.com/profiles/ming-gao-1496188">Ming Gao</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a> In South Korea, a growing number of young women are rejecting societal expectations of marriage, motherhood and heterosexual relationships, known as the “4B Movement” or the “4 Nos”. The “B” is a homophone for the Korean word bi (비/非), meaning “no”, representing the movement’s four principles: bihon (no marriage), bichulsan (no childbirth), biyeonae (no dating) and bisekseu (no sex). By refusing to marry, have children, engage in romance, or participate in sexual relationships with men, 4B feminists seek to redefine their lives outside the confines of traditional gender roles. In the wake of the reelection of Donald Trump, there has been <a href="https://www.abc.net.au/news/2024-11-10/donald-trump-win-4b-movement-male-supremacists-make-threats/104575732">increased interest</a> in the 4B movement from women in the United States. But what is the 4B Movement, where did it come from, and how is it reshaping the feminist landscape in South Korea and beyond? <h2>Challenges facing young women</h2> The 4B Movement reflects <a href="https://www.khan.co.kr/national/national-general/article/202004140938001">a broader dissatisfaction</a> among young South Korean women who face instability of housing, digital sexual violence, economic disparities and cultural pressures. It emerged in the mid- to late-2010s, following a surge of interest in feminism in South Korea, and spread primarily through women’s online communities. The roots of the 4B Movement lie in South Korea’s rapid economic transformation and the subsequent challenges it posed for younger generations of the 2000s. For young women, economic insecurity is compounded by systemic gender inequality. South Korea <a href="https://www.straitstimes.com/asia/east-asia/south-korea-s-gender-pay-gap-worst-in-oecd">consistently ranks</a> worst in the OECD for the gender wage gap, and social mobility remains limited. Against this backdrop, traditional life paths – marriage, childbearing and homemaking – have become less appealing. Living an alternative life without men emerged as a radical strategy for young digital feminists to challenge the rigid patriarchy in South Korea. The <a href="https://www.khan.co.kr/national/national-general/article/202405172212001">senseless killing</a> in 2016 of a woman in a train station toilet by a man in Seoul shocked the nation and fuelled the movement. Online platforms became spaces where women could share their frustrations, critique patriarchal norms and organise protests. During this period communities like radical feminist online groups gained traction. Among these was the <a href="https://www.bbc.com/korean/news-44329328">Tal-Corset</a> (escape the corset) movement, which encouraged women to reject societal beauty standards by foregoing makeup, cosmetic surgery and restrictive clothing. The 4B Movement built on this momentum, targeting not only beauty standards but the very institutions that sustain patriarchy. It collectively challenges the notion that women’s value lies in their ability to support men and sustain the family unit. <h2>‘A woman is not a baby-making machine’</h2> The birth rate in South Korea ranks among the <a href="https://worldpopulationreview.com/country-rankings/birth-rate-by-country">lowest in the world</a>. The government has long viewed this as a national crisis. Policies such as subsidised housing for newlyweds and tax incentives for families have sought to encourage marriage and childbearing. In 2016, the government launched a national <a href="https://www.womennews.co.kr/news/articleView.html?idxno=248514">pink birth map</a> visualising the number of women of reproductive age in each district. It sparked outrage. Women criticised it as reducing them to reproductive tools, proclaiming, “<a href="https://www.nocutnews.co.kr/news/4713565">my womb is not national property</a>” and “<a href="https://www.youtube.com/watch?v=6FsEWD1bi3E">a woman is not a baby-making machine</a>”. For many 4B feminists, these policies represent a stark example of how the state prioritises population growth over women’s autonomy. In response, the movement frames its rejection of marriage and motherhood as an act of political resistance. As one <a href="https://www.womennews.co.kr/news/articleView.html?idxno=111598">protest slogan</a> declared: “End population policies! Stop blaming women”. <h2>Living on their own terms</h2> Despite its growing influence, the 4B Movement faces significant challenges. The radical principles have sparked backlash, with critics labelling participants as selfish or anti-social. Swearing off men as a form of protest against patriarchal structures and traditional marital norms is sometimes (mis)interpreted as implicitly favouring <a href="https://brunch.co.kr/brunchbook/radsview2">lesbianism</a>, given its stance against heterosexual relationships. The movement has also attracted negative political attention. <a href="https://www.khan.co.kr/national/national-general/article/202004140938001">Lee Seung-cheon</a>, a 58-year-old Democratic Party candidate, pledged to introduce “measures to reject the 4B Movement” as part of his policy campaign in 2020. Yet 4B feminists remain steadfast in their vision of a future where women can live on their own terms. Their rejection of traditional life paths is not a retreat into isolation but an attempt to create new ways of being free from patriarchal constraints. As one participant noted, rejecting marriage allows women to envision futures beyond societal deadlines like “<a href="https://brunch.co.kr/@404homealone/34">a woman’s age has an expiration date</a>”. <h2>An international movement</h2> The 4B Movement’s radical critique of patriarchy has resonated internationally. 4B Movement ideas are starting to strike a chord in the US. The movement’s core principles align with broader feminist critiques of patriarchy and capitalism, which have intensified in response to political developments such as Trump’s rhetoric and debates over reproductive rights. In the US, Trump’s presidency (and now his return) has been a flashpoint for feminist activism. Policies restricting access to abortion, coupled with an increase in conservative rhetoric around women’s rights, have galvanised movements that resist patriarchal structures. For American feminists, the 4B Movement offers a framework for resistance that goes beyond economic precarity. It provides a roadmap for rejecting political conflicts, focusing on reclaiming agency by prioritising autonomy over their own bodies and rights. 6B4T is inspired by the 4B Movement and has gained particular attention <a href="https://weibo.com/1263977197/KaFZGjoG4">in China</a>. This version incorporates additional principles, including rejecting consumerism and fostering mutual aid among unmarried women. The spread of 4B ideas across Asia and beyond highlights the universality of feminist struggles. As the movement continues to evolve, its impact extends beyond South Korea, sparking conversations about gender, autonomy and the future of feminism. Whether embraced or contested, the 4B Movement forces society to confront uncomfortable truths about the cost of sustaining patriarchy – and perhaps the possibilities of living without it. <hr /> Correction: 6B4T is inspired by the 4B movement and gained attention in China; it did not originate in China.<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/243355/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/ming-gao-1496188">Ming Gao</a>, Research Scholar, Gender and Women's History Research Centre, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

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

<a href="https://theconversation.com/profiles/myles-david-sergeant-1542267">Myles David Sergeant</a>, <a href="https://theconversation.com/institutions/mcmaster-university-930">McMaster University</a> Extreme heat is a silent killer. From time to time, we hear about shocking cases of <a href="https://www.theguardian.com/world/2023/sep/24/football-player-heat-deaths-athlete">football players</a> and other athletes who die suddenly while exerting themselves on hot days. Those deaths are certainly tragic, but statistically they are very rare. Most deaths from extreme heat <a href="https://www.epa.gov/climate-indicators/climate-change-indicators-heat-related-deaths">are in older people</a>, who frequently die alone inside their homes. They often die slowly, as the heat creeps up to and sometimes past body temperature, especially when heat domes park themselves over cities and keep the temperature high all day and all night. When such deaths happen, they rarely make the news. Of all the climate change disasters our world is already experiencing, heat is the top killer, <a href="https://library.wmo.int/viewer/68500/download?file=1335_WMO-Climate-services-Health_en.pdf&type=pdf&navigator=1">as the World Meteorological Organization reported</a>. The planet was more than <a href="https://www.theguardian.com/environment/article/2024/jul/08/temperatures-1-point-5c-above-pre-industrial-era-average-for-12-months-data-shows">1.5 C above the pre-industrial baseline</a> for 12 consecutive months from July 2023 to June 2024. In July this year, we saw the hottest three days ever on record, prompting <a href="https://www.un.org/sg/en/content/sg/press-encounter/2024-07-25/secretary-generals-press-conference-extreme-heat">a special statement from United Nations Secretary-General Antonio Guterres</a>. <h2>Health risks and heat</h2> <a href="https://www.ncbi.nlm.nih.gov/books/NBK499843/">Our bodies are made to dump excess heat</a> when we are too warm, but that process goes into reverse when the air is warmer than our core temperature. Our other main defence, sweating, doesn’t help when humidity saturates the air, making it impossible for our own moisture to evaporate. For the frail and elderly, who are more likely to be labouring with heart troubles, COPD or other challenges, simply sitting still in a heat wave requires an effort equivalent to walking on a treadmill. The effort is not great, but it is <a href="https://doi.org/10.1016/j.cjco.2021.10.002">steady and relentless</a>. It exhausts the body, sometimes to the <a href="https://doi.org/10.1016/S2542-5196(22)00117-6">point of no return</a>. Tracking heat-related deaths is challenging, and it’s changing as authorities become more aware of heat as a contributing or underlying factor to deaths by other causes. <a href="https://doi.org/10.2105/AJPH.2006.100081">A paper published by the American Journal of Public Health</a> points out that the 1995 heat wave in Chicago likely contributed to hundreds more deaths than had first been attributed to heat itself. <h2>Who is at risk?</h2> Many people lack air conditioning or a way to get to a place that has it, such as a library, recreation centre or shopping mall. As a result, too many people in cities are forced to <a href="https://wmo.int/publication-series/2023-state-of-climate-services-health">endure long waves of heat</a> — waves that are occurring more frequently, lasting longer, and reaching higher temperatures — in a trend that appears set to continue getting worse. Air conditioning, <a href="https://www.lpm.org/news/2015-07-24/the-history-of-movie-theaters-and-air-conditioning-that-keeps-film-lovers-cool">once a luxury that drew people to summertime movie theatres on hot nights</a>, has become a necessity. Increasingly, it is also a legal requirement, as cities pass bylaws requiring landlords not to allow the temperature in their tenants’ quarters to rise above a certain level. Toronto has <a href="https://www.toronto.ca/home/311-toronto-at-your-service/find-service-information/article/?kb=kA06g000001xvbiCAA">such a bylaw</a> for rental units that have air conditioning available, capping indoor temps at 26 C between June 2 and Sept. 14. Such laws recognize the vulnerability of tenants who lack control over the temperature in their rental units, making heat death an especially urban tragedy, as confirmed in <a href="https://www150.statcan.gc.ca/n1/en/pub/82-003-x/2024006/article/00001-eng.pdf?st=e6jLNMuq">a recent Statistics Canada study</a> between 2000 and 2020. Deaths from extreme heat were more likely in cities with a higher percentage of renter households. During a single week-long heat wave in June 2021 — the year after the period captured in the Statistics Canada study — <a href="https://www.cbc.ca/news/canada/british-columbia/bc-heat-dome-sudden-deaths-570-1.6122316">B.C.’s chief coroner found that 570 people died from heat-related causes</a> — 79 per cent of them were seniors. <h2>Taking action at the community level</h2> From this Global North perspective, the community members who are most likely to die from extreme heat included: <ul> <li>Those over 65</li> <li>Those with more than one chronic condition (including hypertension, mental health, diabetes, heart disease, lung disease)</li> <li>Socially disadvantaged populations in our communities</li> <li>Those with mobility issues</li> <li>Those experiencing social isolation (living alone)</li> <li>Tenants with lack of air conditioning</li> <li>Those living in an urban heat island</li> </ul> This problem is not going away. Some of the <a href="https://www.intactcentreclimateadaptation.ca/wp-content/uploads/2022/06/UoW_ICCA_2022_04-Irreversible-Extreme-Heat.pdf">actions we can take</a> to protect our most vulnerable community members include: <ul> <li>Increase awareness that excessive heat is not merely uncomfortable, but dangerous.</li> <li>Make sure people are warned about impending heat waves.</li> <li>Advocate for everyone to have access to air conditioning.</li> <li>Check on and support people who live alone, especially those with no air conditioning.</li> <li>Invite people over if you have air conditioning, or help them get to community cooling stations.</li> <li>Help vulnerable people who do not have air conditioning to improvise, by freezing wet cloths, for example, to take out and hang around their necks. Doing this, especially with a fan blowing, can be surprisingly effective.</li> <li>Learn and share the <a href="https://www.canada.ca/en/health-canada/services/publications/healthy-living/fact-sheet-staying-healthy-heat.html">warning signs of heat-related illness</a>.</li> <li>Make sure they drink plenty of water and other replenishing fluids.</li> </ul> While we must do our best to limit climate change to keep our planet from getting ever hotter, we must also make every effort to protect the vulnerable from the impacts of the heat that is already here.<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/236829/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/myles-david-sergeant-1542267">Myles David Sergeant</a>, Assistant Clinical Professor, Department of Family Medicine, <a href="https://theconversation.com/institutions/mcmaster-university-930">McMaster University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What are the four waves of feminism? And what comes next?

<a href="https://theconversation.com/profiles/sharon-crozier-de-rosa-122804">Sharon Crozier-De Rosa</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a> In Western countries, feminist history is generally packaged as a story of “waves”. The so-called first wave lasted from the mid-19th century to 1920. The second wave spanned the 1960s to the early 1980s. The third wave began in the mid-1990s and lasted until the 2010s. Finally, some say we are experiencing a fourth wave, which began in the mid-2010s and continues now. The first person to use “waves” was journalist Martha Weinman Lear, in her 1968 New York Times article, <a href="https://www.nytimes.com/1968/03/10/archives/the-second-feminist-wave.html">The Second Feminist Wave</a>, demonstrating that the women’s liberation movement was another <a href="https://www.vox.com/2018/3/20/16955588/feminism-waves-explained-first-second-third-fourth">“new chapter</a> in a grand history of women fighting together for their rights”. She was responding to anti-feminists’ framing of the movement as a “<a href="https://www.vox.com/2018/3/20/16955588/feminism-waves-explained-first-second-third-fourth">bizarre historical aberration</a>”. <a href="https://www.journals.uchicago.edu/doi/abs/10.1086/718868">Some feminists</a> criticise the usefulness of the metaphor. Where do feminists who preceded the first wave sit? For instance, Middle Ages feminist writer <a href="https://blogs.loc.gov/bibliomania/2023/08/30/christine-de-pizan/">Christine de Pizan</a>, or philosopher <a href="https://plato.stanford.edu/entries/wollstonecraft/">Mary Wollstonecraft</a>, author of <a href="https://www.penguin.com.au/books/a-vindication-of-the-rights-of-woman-9780141441252">A Vindication of the Rights of Woman</a> (1792). Does the metaphor of a single wave <a href="https://www.vox.com/2018/3/20/16955588/feminism-waves-explained-first-second-third-fourth">overshadow</a> the complex variety of feminist concerns and demands? And does this language exclude the <a href="https://www.journals.uchicago.edu/doi/abs/10.1086/718868">non-West</a>, for whom the “waves” story is meaningless? Despite these concerns, countless feminists <a href="https://www.researchgate.net/publication/317322421_Finding_a_Place_in_History_The_Discursive_Legacy_of_the_Wave_Metaphor_and_Contemporary_Feminism">continue to use</a> “waves” to explain their position in relation to previous generations. <h2>The first wave: from 1848</h2> The first wave of feminism refers to the campaign for the vote. It began in the United States in 1848 with the <a href="https://www.loc.gov/exhibitions/women-fight-for-the-vote/about-this-exhibition/seneca-falls-and-building-a-movement-1776-1890/">Seneca Falls Convention</a>, where 300 gathered to debate Elizabeth Cady Stanton’s Declaration of Sentiments, outlining women’s inferior status and demanding suffrage – or, the right to vote. It continued over a decade later, in 1866, in Britain, with the presentation of a <a href="https://www.parliament.uk/about/living-heritage/transformingsociety/electionsvoting/womenvote/parliamentary-collections/1866-suffrage-petition/presenting-the-petition/">suffrage petition</a> to parliament. This wave ended in 1920, when women were granted the right to vote in the US. (Limited women’s suffrage had been introduced in Britain two years earlier, in 1918.) First-wave activists believed once the vote had been won, women could use its power to enact other much-needed reforms, related to property ownership, education, employment and more. White leaders dominated the movement. They included longtime president of the the International Woman Suffrage Alliance <a href="https://cattcenter.iastate.edu/home/about-us/carrie-chapman-catt/">Carrie Chapman Catt</a> in the US, leader of the militant Women’s Social and Political Union <a href="https://www.britannica.com/biography/Emmeline-Pankhurst">Emmeline Pankhurst</a> in the UK, and <a href="https://adb.anu.edu.au/biography/spence-catherine-helen-4627">Catherine Helen Spence</a> and <a href="https://adb.anu.edu.au/biography/goldstein-vida-jane-6418">Vida Goldstein</a> in Australia. This has tended to obscure the histories of non-white feminists like evangelist and social reformer <a href="https://www.britannica.com/biography/Sojourner-Truth">Sojourner Truth</a> and journalist, activist and researcher <a href="https://www.womenshistory.org/education-resources/biographies/ida-b-wells-barnett">Ida B. Wells</a>, who were fighting on multiple fronts – including anti-slavery and anti-lynching – as well as feminism. <h2>The second wave: from 1963</h2> The second wave coincided with the publication of US feminist Betty Friedan’s <a href="https://www.penguin.com.au/books/the-feminine-mystique-9780141192055">The Feminine Mystique</a> in 1963. Friedan’s “<a href="https://www.smithsonianmag.com/smithsonian-institution/powerful-complicated-legacy-betty-friedans-feminine-mystique-180976931/">powerful treatise</a>” raised critical interest in issues that came to define the women’s liberation movement until the early 1980s, like workplace equality, birth control and abortion, and women’s education. Women came together in “consciousness-raising” groups to share their individual experiences of oppression. These discussions informed and motivated public agitation for <a href="https://www.berghahnbooks.com/title/HaeberlenPolitics">gender equality and social change</a>. Sexuality and gender-based violence were other prominent second-wave concerns. Australian feminist Germaine Greer wrote <a href="https://www.harpercollins.com.au/9780007205011/the-female-eunuch/">The Female Eunuch</a>, published in 1970, which <a href="https://theconversation.com/friday-essay-the-female-eunuch-at-50-germaine-greers-fearless-feminist-masterpiece-147437">urged women to</a> “challenge the ties binding them to gender inequality and domestic servitude” – and to ignore repressive male authority by exploring their sexuality. Successful lobbying saw the establishment of refuges for women and children fleeing domestic violence and rape. In Australia, there were groundbreaking political appointments, including the world’s first Women’s Advisor to a national government (<a href="https://www.nma.gov.au/audio/landmark-women/transcripts/landmark-women-elizabeth-reid-181013.mp3-transcript">Elizabeth Reid</a>). In 1977, a <a href="https://www.whitlam.org/women-and-whitlam">Royal Commission on Human Relationships</a> examined families, gender and sexuality. Amid these developments, in 1975, Anne Summers published <a href="https://theconversation.com/damned-whores-and-gods-police-is-still-relevant-to-australia-40-years-on-mores-the-pity-47753">Damned Whores and God’s Police</a>, a scathing historical critique of women’s treatment in patriarchal Australia. At the same time as they made advances, so-called women’s libbers managed to anger earlier feminists with their distinctive claims to radicalism. Tireless campaigner <a href="https://adb.anu.edu.au/biography/rich-ruby-sophia-14202">Ruby Rich</a>, who was president of the Australian Federation of Women Voters from 1945 to 1948, responded by declaring the only difference was her generation had called their movement “<a href="https://nla.gov.au/nla.obj-296328435/findingaid">justice for women</a>”, not “liberation”. Like the first wave, mainstream second-wave activism proved largely irrelevant to non-white women, who faced oppression on intersecting gendered and racialised grounds. African American feminists produced their own critical texts, including bell hooks’ <a href="https://www.routledge.com/Aint-I-a-Woman-Black-Women-and-Feminism/hooks/p/book/9781138821514">Ain’t I a Woman? Black Women and Feminism</a> in 1981 and Audre Lorde’s <a href="https://www.penguinrandomhouse.com/books/198292/sister-outsider-by-audre-lorde/">Sister Outsider</a> in 1984. <h2>The third wave: from 1992</h2> The third wave was announced in the 1990s. The term is popularly attributed to Rebecca Walker, daughter of African American feminist activist and writer <a href="https://alicewalkersgarden.com/about/">Alice Walker</a> (author of <a href="https://www.hachette.com.au/alice-walker/the-color-purple-now-a-major-motion-picture-from-oprah-winfrey-and-steven-spielberg">The Color Purple</a>). Aged 22, Rebecca proclaimed in a 1992 Ms. magazine <a href="https://web.archive.org/web/20200404030632/http:/heathengrrl.blogspot.com/2007/02/becoming-third-wave-by-rebecca-walker.html">article</a>: “I am not a post-feminism feminist. I am the Third Wave.” Third wavers didn’t think gender equality had been more or less achieved. But they did share <a href="https://journals.sagepub.com/doi/10.1177/1464700119842555">post-feminists</a>’ belief that their foremothers’ concerns and demands were obsolete. They argued women’s experiences were now shaped by <a href="https://www.tandfonline.com/doi/full/10.1080/14680777.2016.1190046">very different</a> political, economic, technological and cultural conditions. The third wave has been described as “an <a href="https://www.smh.com.au/lifestyle/beauty/meet-the-woman-who-coined-the-term-third-wave-feminism-20180302-p4z2mw.html">individualised feminism</a> that can not exist without diversity, sex positivity and intersectionality”. Intersectionality, <a href="https://chicagounbound.uchicago.edu/cgi/viewcontent.cgi?article=1052&context=uclf">coined</a> in 1989 by African American legal scholar Kimberlé Crenshaw, recognises that people can experience intersecting layers of oppression due to race, gender, sexuality, class, ethnicity and more. Crenshaw notes this was a “lived experience” before it was a term. In 2000, Aileen Moreton Robinson’s <a href="https://www.uqp.com.au/books/talkin-up-to-the-white-woman-indigenous-women-and-feminism-20th-anniversary-edition">Talkin’ Up to the White Woman: Indigenous Women and Feminism</a> expressed Aboriginal and Torres Strait Islander women’s frustration that white feminism did not adequately address the legacies of dispossession, violence, racism, and sexism. Certainly, the third wave accommodated <a href="https://paromitapain.com/wp-content/uploads/2019/12/10.10072F978-3-319-72917-6.pdf#page=112%22">kaleidoscopic views</a>. Some scholars claimed it “grappled with fragmented interests and objectives” – or micropolitics. These included ongoing issues such as sexual harassment in the workplace and a scarcity of women in positions of power.

This era is marked by mass online mobilisation. The fourth wave generation is connected via new communication technologies in ways that were not previously possible. Online mobilisation has led to spectacular street demonstrations, including the #metoo movement. #Metoo was first founded by Black activist <a href="https://www.womenshistory.org/education-resources/biographies/tarana-burke">Tarana Burke</a> in 2006, to support survivors of sexual abuse. The hashtag #metoo then went viral during the 2017 Harvey Weinstein <a href="https://www.npr.org/2022/10/28/1131500833/me-too-harvey-weinstein-anniversary">sexual abuse scandal</a>. It was used at least <a href="https://www.sciencedirect.com/science/article/abs/pii/S0747563221002193">19 million times</a> on Twitter (now X) alone. In January 2017, the <a href="https://www.womensmarch.com/">Women’s March</a> protested the inauguration of the decidedly misogynistic Donald Trump as US president. <a href="https://www.britannica.com/event/Womens-March-2017">Approximately 500,000</a> women marched in Washington DC, with demonstrations held simultaneously in <a href="https://www.routledge.com/Remembering-Womens-Activism/Crozier-De-Rosa-Mackie/p/book/9781138794894">81 nations</a> on all continents of the globe, even Antarctica. In 2021, the <a href="https://catalogue.nla.gov.au/catalog/8564388">Women’s March4Justice</a> saw some 110,000 women rallying at more than 200 events across Australian cities and towns, protesting workplace sexual harassment and violence against women, following high-profile cases like that of Brittany Higgins, revealing <a href="https://www.theguardian.com/australia-news/2023/nov/29/brittany-higgins-bruce-lehrmann-defamation-trial-evidence-stand-rape-allegations-liberal-party-ntwnfb#:%7E:text=Bruce%20Lehrmann%20has%20brought%20a,Wilkinson%20are%20defending%20the%20case.">sexual misconduct</a> in the Australian houses of parliament. Given the prevalence of online connection, it is not surprising fourth wave feminism has reached across geographic regions. The Global Fund for Women <a href="https://www.globalfundforwomen.org/movements/me-too/">reports</a> that #metoo transcends national borders. In China, it is, among other things, #米兔 (translated as “<a href="https://www.ft.com/content/61903744-9540-11e8-b67b-b8205561c3fe">rice bunny</a>”, pronounced as “mi tu”). In Nigeria, it’s <a href="https://www.youtube.com/watch?v=we-F0Gi0Lqs">#Sex4Grades</a>. In Turkey, it’s #<a href="https://ahvalnews.com/sexual-harrasment/dozens-turkish-womens-organisations-issue-statement-backing-latest-metoo-movement">UykularınızKaçsın</a> (“may you lose sleep”). In an inversion of the traditional narrative of the Global North leading the Global South in terms of feminist “progress”, Argentina’s “<a href="https://www.auswhn.com.au/blog/colour-green/">Green Wave</a>” has seen it decriminalise abortion, as has Colombia. Meanwhile, in 2022, the US Supreme Court <a href="https://theconversation.com/us-supreme-court-overturns-roe-v-wade-but-for-abortion-opponents-this-is-just-the-beginning-185768">overturned historic abortion legislation</a>. Whatever the nuances, the prevalence of such highly visible gender protests have led some feminists, like <a href="https://www.tandfonline.com/doi/abs/10.1080/14680777.2020.1804431">Red Chidgey</a>, lecturer in Gender and Media at King’s College London, to declare that feminism has transformed from “a dirty word and publicly abandoned politics” to an ideology sporting “a new cool status”. <h2>Where to now?</h2> How do we know when to pronounce the next “wave”? (Spoiler alert: I have no answer.) Should we even continue to use the term “waves”? The “wave” framework was first used to demonstrate feminist continuity and solidarity. However, whether interpreted as disconnected chunks of feminist activity or connected periods of feminist activity and inactivity, represented by the crests and troughs of waves, some believe it encourages binary thinking that produces <a href="https://www.tandfonline.com/doi/full/10.1080/14680777.2016.1190046">intergenerational antagonism</a>. Back in 1983, Australian writer and second-wave feminist Dale Spender, who died last year, <a href="https://www.historyworkshop.org.uk/feminism/radical-books-dale-spender-theres-always-been-a-womens-movement-this-century-1983/">confessed her fear</a> that if each generation of women did not know they had robust histories of struggle and achievement behind them, they would labour under the illusion they’d have to develop feminism anew. Surely, this would be an overwhelming prospect. What does this mean for “waves” in 2024 and beyond? To build vigorous varieties of feminism going forward, we might reframe the “waves”. We need to let emerging generations of feminists know they are not living in an isolated moment, with the onerous job of starting afresh. Rather, they have the momentum created by generations upon generations of women to build on.<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/224153/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/sharon-crozier-de-rosa-122804">Sharon Crozier-De Rosa</a>, Professor, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Tech millionaire’s “creepy” $100k offer sparks wave of backlash

US tech millionaire and Silicon Valley entrepreneur Steve Kirsch has been slammed for making a “creepy” offer towards a female passenger who was travelling on the same plane. In a tweet, Kirsch claimed that he offered the stranger $US100,000 to remove her face mask for the flight. "I am on board a Delta flight right now. The person sitting next to me in first-class refused $100,000 to remove her mask for the entire flight. No joke," he tweeted. Kirsch, who became infamous for spreading misinformation about the COVID-19 vaccines throughout the pandemic, said that he "explained" to his seatmate that masks "don’t work". He also claims that the woman worked for a pharmaceutical company, and he started by offering her $US100 but worked his way up. She rejected his offer, but Kirsch persisted and said that if she removed the mask to eat and drink she "she could be infected with one breath". Many have slammed the entrepreneur for his actions. “Ew. Do you make a habit of offering money to random women to remove coverings from their bodies mid-air?" posted Jess Piper, a former Democrat state representative nominee, in her response to Kirsch's post. “Stop bugging people who are minding their own business with your creepy nonsense,” commented Alastair McAlpine, an infectious disease expert. <blockquote class="twitter-tweet"> I am on board a Delta flight right now. The person sitting next to me in first class refused $100,000 to remove her mask for the entire flight. No joke. This was after I explained they don’t work.

Every part of this. From the request, to the expression, to the fact you decided to tweet this!" commented one user. “All you’re doing here is admitting you patronised and harassed a woman who made a decision she thought was best for her,” wrote another. Last week, Kirsch tried to pull the same stunt on a different flight. He tweeted that he offered his seatmates $US10,000 to remove their masks for the flight, but they also declined his offer. <blockquote class="twitter-tweet"> I asked the people sitting next to me on the plane if I paid them $10,000 would they remove their mask for the duration of the flight? Both declined the offer. Maybe I should offer $100,000 next time? This can quantify the amount of brainwashing. <a href="https://t.co/VLlymusmcq">pic.twitter.com/VLlymusmcq</a> — Steve Kirsch (@stkirsch) <a href="https://twitter.com/stkirsch/status/1633166204054675456?ref_src=twsrc%5Etfw">March 7, 2023</a></blockquote> "Maybe I should offer $100,000 next time? This can quantify the amount of brainwashing," he added. Delta airlines have said that masks are optional for both domestic and international travel unless required by “applicable governments”. American federal law no longer requires masks be worn in airports or on planes, but certain cities and states may still make it a requirement at their airports. Image: Twitter

"Thermonuclear bad": Millions of deaths expected in China's Covid wave

Experts have warned deaths will be "in the millions" as China faces an unprecedented Covid wave, which is set to become "thermonuclear bad". The most recent wave of the infections began after Chinese President Xi Jinping finally began to relax his "zero-Covid" policy, which has seen the country under heavy lockdowns for months at a time. Within days of the restrictions easing, Covid cases began to explode, with hospitals already “completely overwhelmed” and bodies reportedly piling up at morgues. Public health officials in China have admitted it is possible that 800 million people could be struck down by Covid in the coming months. However, the nation has officially recorded just two deaths since reopening, although there are now widespread reports that the true figure is far higher, with workers at the Beijing Dongjiao Funeral Parlour – the venue tasked with handling Covid deaths – claiming they were overwhelmed with bodies in recent days. The claims have sparked rumours of a government cover up, with international experts sounding the alarm over a tragedy in the making. Harvard-trained US epidemiologist Eric Feigl-Ding recently shared a video on Twitter purportedly showing rows of seriously ill Covid patients crammed into a clearly stretched hospital, with some seen lying on the floor or slumped in chairs, warning that things were getting “thermonuclear bad”. <blockquote class="twitter-tweet"> ⚠️THERMONUCLEAR BAD—Hospitals completely overwhelmed in China ever since restrictions dropped. Epidemiologist estimate >60% of 🇨🇳 & 10% of Earth’s population likely infected over next 90 days. Deaths likely in the millions—plural. This is just the start—🧵<a href="https://t.co/VAEvF0ALg9">pic.twitter.com/VAEvF0ALg9</a> — Eric Feigl-Ding (@DrEricDing) <a href="https://twitter.com/DrEricDing/status/1604748747640119296?ref_src=twsrc%5Etfw">December 19, 2022</a></blockquote> “Hospitals completely overwhelmed in China ever since restrictions dropped,” he posted, adding that epidemiologists estimate more than 60 per cent of China and 10 per cent of the Earth’s population is likely to be infected with the virus over the next 90 days. “Deaths likely in the millions – plural. This is just the start,” he posted. His claims were backed up by a recent forecast by health data analysts Airfinity, which predicted China faces between 1.3 and 2.1 million deaths between now and the end of March. Fellow epidemiologist Ben Cowling agreed with the terrifying figures, telling <a href="https://www.npr.org/sections/goatsandsoda/2022/12/15/1143002538/china-appears-to-be-facing-what-could-be-the-world-s-largest-coronavirus-outbrea" target="_blank" rel="noopener">NPR</a> the surge is “going to come very fast, unfortunately”, and predicting that “hospitals are going to come under pressure possibly by the end of this month”. Dr Eric Feigl-Ding went on to explain that nobody would be immune to the fallout from China’s latest crisis, predicting that the world would soon be hit by severe shortages of crucial medical supplies including antibiotics and fever medications. “What happens in China doesn’t stay in China — Wuhan was our lesson three years ago. The global fallout of this 2022-2023 wave will not be small,” he warned, adding that he believed the “global economic fallout from China’s new mega tsunami wave will be ugly”. Image credits: Twitter

Passenger killed after “rogue wave” strikes cruise ship

An elderly woman has died and four others have been injured after a massive wave struck a cruise ship sailing towards southern Argentina at the end of its Antarctic cruise. The Viking Polaris was struck by a wave that broke cabin windows during a storm on its return to the port of Ushuaia last week, according to Argentinian authorities. While the ship suffered minimal damage, the 62-year-old US woman who was hit by broken glass died. “It is with great sadness that we confirm a guest passed away following the incident,” Viking said in a statement. “We have notified the guest’s family and shared our deepest sympathies.” The cruise operator described it as a “rogue wave incident” and confirmed that four other cruise goers suffered non-life threatening injuries and received treatment from the doctor and medical staff on board the ship. With a federal court opening a case into the incident, the cruise ship has been anchored at Ushuaia. Viking has also said it would investigate the incident and “offer our support to the relevant authorities”. “Our focus remains on the safety and wellbeing of our guests and crew, and we are working directly with them to arrange return travel,” the <a href="https://www.vikingcruises.co.uk/expeditions/my-trip/current-sailings/index.html">statement</a> from Thursday, December 1, read. The company has also cancelled its scheduled voyage to Antarctica, which was due to depart from December 5-17. The Polaris, built this year, features luxury facilities and has capacity for 378 passengers and 256 crew members. It is one of two ships Viking has for its cruises, which explore remote regions of the world. Image: Getty Images

Democracy spreads in waves – but shared cultural history might matter more than geography

Recent events like the war in Ukraine, conflicts over Taiwan and the rise of authoritarian ideology have renewed interest in the foundations of modern democracy. They have raised questions about why some nations are more democratic than others, and how democratic institutions, freedoms and values are spread or lost. We tend to think of this variation in terms of geography – democratic Western Europe or autocratic Middle East. But in a <a href="https://www.cambridge.org/core/journals/evolutionary-human-sciences/article/shared-cultural-ancestry-predicts-the-global-diffusion-of-democracy/90C7A170B924FC305DD66FF8853799FC" target="_blank" rel="noopener">new analysis of 220 years of political data</a>, we show that deep cultural connections between countries such as shared linguistic or religious ancestry matter more than geography. <h2>Waves of democratisation</h2> The emergence of modern democracy coincides with the rise of nation states in Europe at the beginning of the 19th century. Democracy spread across European nations and their colonies, over <a href="https://en.wikipedia.org/wiki/The_Third_Wave:_Democratization_in_the_Late_Twentieth_Century" target="_blank" rel="noopener">three waves</a>. The first wave lasted about a century, from 1828 to 1926, halting after the first world war. A second, rapid wave (1945-1962) followed the second world war and decolonisation. The third wave began in 1974 and continues today. It encompassed political transitions and new countries in Europe, Latin America and the Pacific. Each wave was followed by a period of reversals when nations turned to autocratic regimes, junta or fascism. Indeed, some researchers speculate we are heading into <a href="https://www.tandfonline.com/doi/full/10.1080/13510347.2019.1582029" target="_blank" rel="noopener">another period of reversal</a>. <h2>What drives modern democracy?</h2> Scholars traditionally considered factors internal to a country – economic growth, rates of education or the natural environment – as the drivers of these waves. However, the geographic clustering of democracy and the wave-like pattern of expansion suggest the process may also involve a kind of contagion where democracy passes from one nation to another. One explanation for this is that democratic change spreads across borders, so that neighbouring countries end up with similar levels of democracy. Culture provides another explanation. Neighbouring countries tend to share a common cultural heritage, such as related languages or religions. This shapes national institutions, norms and values. In our research, we tested the idea that common cultural ancestry explains variation and change in democracy around the globe. We brought together 220 years of democracy data with information on the cultural relationships between nations. The cultural relationships we examined were based on languages and religious beliefs. For example, Portugal is linguistically closer to Spanish-speaking Argentina and Spain than to England and Germany (which speak Germanic languages). Likewise, Myanmar, a Theravada Buddhist country, is religiously closer to Mongolia (where Vajrayana Buddhism is predominant) than to Muslim Malaysia. <h2>Culture is more important than geography</h2> The democracy data we studied cover 269 modern and historical nations and three widely-used democracy indicators, measuring democratic and autocratic authority in governing institutions (<a href="https://www.systemicpeace.org/polityproject.html" target="_blank" rel="noopener">Polity 5</a>), electoral participation and competition (<a href="https://www.prio.org/data/20" target="_blank" rel="noopener">Vanhanen Index</a>) and individual rights and freedoms (<a href="https://freedomhouse.org/" target="_blank" rel="noopener">Freedom House</a>). Across all three indicators of democracy, we found countries that share linguistic or religious ancestry tend to have more similar democracy scores. These shared cultural ties were better predictors of democracy than geography, especially during the third wave of democratisation. Knowing the democratic status of a country’s linguistic or religious relatives helps predict that country’s future level of democracy five, ten or even 20 years later. These effects were not just due to countries sharing a language (for example, the English-speaking world) or religion (such as the Sunni Islam majority countries). This suggests deeper cultural connections between countries are important. <h2>What this means for the spread of democracy</h2> These effects could be the result of a number of processes. One possibility is that countries directly inherited institutions along the same pathways they inherited cultural features like language. For instance, Aotearoa New Zealand and other Commonwealth countries inherited the British legal system along with the English language. Another possibility is that cultural similarities might make countries more likely to maintain ongoing social connections, including foreign relations, which then aid the spread of institutions. For example, the <a href="https://theconversation.com/how-the-arab-spring-changed-the-middle-east-and-north-africa-forever-161394" target="_blank" rel="noopener">Arab Spring</a> spread among a set of countries with common linguistic and religious heritage. A third possibility is that inherited cultural values could steer countries towards similar institutions. For example, <a href="https://www.nature.com/articles/s41562-019-0769-1" target="_blank" rel="noopener">in previous research</a> we found that tolerance of diversity (cosmopolitan values) promotes a shift to more democratic institutions, but the reverse is not true. Democratic institutions do not shift tolerance. Countries that have inherited cosmopolitan values as part of their shared cultural ancestry may be more likely to shift towards democracy. If this theory is correct, it calls into question the assumption that democratic institutions can endure without sustained efforts to promote the cultural values that support them. The US interventions in Afghanistan and Iraq may be tragic examples of this. Our findings indicate cultural history matters for understanding the spread of democracy around the globe. This does not mean culture is the only factor at play (our analyses still leave a lot of variation unexplained). Neither do our findings speak to a population’s ultimate potential to achieve democratic outcomes, but we see this as within the reach of all populations. This means those wishing to support democracy at home or abroad should take cultural barriers seriously. We cannot assume that institutions that work well in one cultural setting can be easily transplanted to another, very different setting, with different values, norms and traditions. We should pay more attention to culturally closely related countries that have succeeded at merging local norms and values with democratic institutions.

Wedding swamped by massive waves

A wedding in Hawaii has been derailed after massive waves sent tables and chairs crashing towards guests. Wild weather that included waves over six-metres tall - attributed to high tides and rising sea levels associated with climate change - ravaged the island’s south shores over the weekend, according to the National Weather Service. Sara Ackerman, one of the attendees at the wedding in Kailua-Kona, filmed the terrifying scene that happened about five minutes before the ceremony was due to start. “I was filming it and then it just came over the wall and just completely annihilated all the tables and chairs,” she said. “It wasn’t like a life-threatening situation by any means whatsoever. It was just like, ‘Oh my gosh … What are we going to do?

So it was great for the photos.” The weather wasn’t just ruining weddings, with waves crashing into homes and businesses, and spilling across highways, as reported by <a href="https://www.9news.com.au/world/hawaii-waves-swamp-homes-weddings-during-historic-swell/24f3ac40-49a2-4fc4-9c0a-81257e7ea7d6" target="_blank" rel="noopener">9News</a>. Lifeguards and rescue crews across the state were occupied by the weather, conducting at least 1,960 rescues on the island of Oahu alone over two days. One serious injury was reported by Honolulu officials, where a surfer suffered a laceration to the back of his head. Chris Benchley, the meteorologist in charge at the National Weather Service’s office in Honolulu, said waves of this size were incredibly rare. “Waves over 12 or 15 feet (3.66 or 4.57 metres), those become extremely big and really rare to have," he said. “It’s the largest it’s been in several decades.” He explained that the swell was produced in the South Pacific, which recently experienced a “particularly strong winter storm” with winds focused directly at Samoa and Hawaii. Though it’s hard to pin the blame for this single weather event directly on climate change, Brenchley said it does play a role. “The most direct type of impact that we can use with climate change is the sea level rise,” he said. “Any time you add just even small amounts of water, you raise that sea level just a little bit. And now those impacts will be exacerbated whenever we have a large storm event or a ... high, high tide.” “We had some waves that were reaching 20 feet (6 metres), 20 feet-plus even,” Brenchley added. “That’s getting on the level of historic.” Image: 9News

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

Despite Mastercard’s <a href="https://wwmastw.cnbc.com/2022/05/17/mastercard-launches-tech-that-lets-you-pay-with-your-face-or-hand.html" target="_blank" rel="noopener">efforts</a> to ensure security, there’s no guarantee the third-party providers’ databases – with potentially millions of people’s biometric data – won’t be hacked. In the wrong hands, this data could lead to <a href="https://www.comparitech.com/identity-theft-protection/identity-theft-statistics/" target="_blank" rel="noopener">identity theft</a>, which is one of the fastest growing types of crime, and financial fraud. Do we want it? Mastercard suggests 74% of customers are in favour of using such technology, referencing a stat from its <a href="https://www.mastercard.com/news/ap/en/newsroom/press-releases/en/2020/april/mastercard-study-shows-consumers-moving-to-contactless-payments-for-everyday-purchases/" target="_blank" rel="noopener">own study</a> – also used by <a href="https://www.mastercard.com/news/ap/en/newsroom/press-releases/en/2020/october/mastercard-idemia-and-matchmove-pilot-fingerprint-biometric-card-in-asia-to-enhance-security-and-safety-of-contactless-payments" target="_blank" rel="noopener">business partner</a> Idemia (a company that sells biometric identification products). But the report cited is vague and brief. Other studies show entirely different results. For example, <a href="https://www.getapp.com/resources/facial-recognition-technology/#how-comfortable-are-consumers-with-facial-recognition-technology" target="_blank" rel="noopener">this study</a> suggests 69% of customers aren’t comfortable with face recognition tech being used in retail settings. And <a href="https://www.securitymagazine.com/articles/93521-are-consumers-comfortable-with-facial-recognition-it-depends-says-new-study" target="_blank" rel="noopener">this one</a> shows only 16% trust such tech.

Grace Tame makes waves at comedy show

Grace Tame has tried her hand at comedy to the delight of attendees at the Melbourne International Comedy Festival.

After monologues from Ilic, Gabbi Bolt, Alice Fraser and Dane Simpson, it was Ms Tame’s turn. She joked that she wasn’t going to get political, apologising to anyone who came to see her take aim at Mr Morrison - at least not directly. “Grace Tame referring to no particular politician as ‘A giant self-saucing joke pudding’,” one attendee tweeted about Ms Tame’s monologue. <blockquote class="twitter-tweet"> Wow! <a href="https://twitter.com/ARationalFear?ref_src=twsrc%5Etfw">@ARationalFear</a> was extraordinary...

One of the characters who “sharted in Old MacDonald’s farm” was a particularly clear reference to the longstanding rumour that Mr Morrison soiled himself at a McDonald’s in Engadine in 1997. Ms Tame didn’t just focus on the PM, going on to describe NSW One Nation leader Mark Latham as her “favourite comedian”. A joke about someone claiming Tasmania wasn’t a real place led to Tame saying it was okay because she lived ‘rent-free’ in Mr Latham’s head, along with domestic violence campaigner Rosie Batty (who he has publicly attacked), the 2004 election results (which saw him lost as Labor leader), and anyone who wasn’t a white man. <blockquote class="twitter-tweet"> To be clear, this isn’t a “career move”.

It’s my life and purpose. I ummed and aahed over whether or not this was the right thing to do,” she wrote on Sunday morning. “There are risks in doing this, as there are with just about anything else in this mad life. “Things have been especially tough lately. But I reckon we could use a laugh. Either way, the joke’s on me. And if I fail, I’ll pick myself up and move. “You never know unless you try.” The show, which also included Lewis Hobba and independent candidate Goldstein Zoe Danila as a special guest, was recorded and will be released as an episode of Ilic’s podcast A Rational Fear.

What causes a tsunami? An ocean scientist explains the physics of these destructive waves

On Jan. 15, 2022, the Hunga Tonga-Hunga Ha’apai volcano in Tonga erupted, sending a tsunami racing across the Pacific Ocean in all directions. As word of the eruption spread, government agencies on surrounding islands and in places as far away as New Zealand, Japan and even the U.S. West Coast issued tsunami warnings. Only about 12 hours after the initial eruption, tsunami waves a few feet tall <a href="https://www.cnn.com/2022/01/15/asia/tsunami-warning-tonga-volcano-intl-hnk/index.html">hit California shorelines</a> – more than 5,000 miles away from the eruption. I’m a <a href="https://scholar.google.com/citations?user=kAGkuGgAAAAJ&hl=en&oi=ao">physical oceanographer</a> who studies waves and turbulent mixing in the ocean. Tsunamis are one of my favorite topics to teach my students because the physics of how they move through oceans is so simple and elegant. Waves that are a few feet tall hitting a beach in California might not sound like the destructive waves the term calls to mind, nor what you see in <a href="https://www.youtube.com/watch?v=QhdSbCUn-oE">footage of tragic tsunamis from the past</a>. But tsunamis are not normal waves, no matter the size. So how are tsunamis different from other ocean waves? What generates them? How do they travel so fast? And why are they so destructive? <a href="https://images.theconversation.com/files/441389/original/file-20220118-17-1wdrep5.gif?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/441389/original/file-20220118-17-1wdrep5.gif?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="A satellite view a large ash cloud and shockwave." /></a> When the Hunga Tonga-Hunga Ha'apai volcano erupted, it launched ash into the atmosphere, created a powerful shock wave and displaced a huge amount of water, generating a tsunami that raced across the ocean. <a href="https://commons.wikimedia.org/wiki/File:Tonga_Volcano_Eruption_2022-01-15_0410Z_to_0550Z.gif#/media/File:Tonga_Volcano_Eruption_2022-01-15_0410Z_to_0550Z.gif" class="source">Japan Meteorological Agency via WikimediaCommons</a>, <a href="http://creativecommons.org/licenses/by/4.0/" class="license">CC BY</a> <h2>Deep displacement</h2> Most waves are <a href="https://theconversation.com/what-makes-the-worlds-biggest-surfable-waves-150600">generated by wind</a> as it blows over the ocean’s surface, transferring energy to and displacing the water. This process creates the waves you see at the beach every day. Tsunamis are created by an entirely different mechanism. When an underwater earthquake, volcanic eruption or landslide displaces a large amount of water, that energy has to go somewhere – so it generates a series of waves. Unlike wind-driven waves where the energy is confined to the upper layer of the ocean, the energy in a series of tsunami waves extends throughout the entire depth of the ocean. Additionally, a lot more water is displaced than in a wind-driven wave. Imagine the difference in the waves that are created if you were to blow on the surface of a swimming pool compared to the waves that are created when someone jumps in with a big cannonball dive. The cannonball dive displaces a lot more water than blowing on the surface, so it creates a much bigger set of waves. Earthquakes can easily move huge amounts of water and cause dangerous tsunamis. Same with large undersea landslides. In the case of the Tonga tsunami, the massive explosion of the volcano displaced the water. Some scientists are speculating that the eruption <a href="https://youtu.be/B54HbfqDbK4">also caused an undersea landslide</a> that contributed to the large amount of displaced water. Future research will help confirm whether this is true or not. <iframe width="440" height="260" src="https://www.youtube.com/embed/etVdMBjAVm0?wmode=transparent&start=0" frameborder="0" allowfullscreen=""></iframe> This simulation from the National Oceanic and Atmospheric Administration shows how tsunami waves propagated away from an earthquake that occurred about 600 miles from Tonga in 2021. <h2>Tsunami waves travel fast</h2> No matter the cause of a tsunami, after the water is displaced, <a href="https://www.youtube.com/playlist?list=PL3BDBAAAA7D4EB2DA">waves propagate outward</a> in all directions – similarly to when a stone is thrown into a serene pond. Because the energy in tsunami waves reaches all the way to the bottom of the ocean, the depth of the sea floor is the primary factor that determines how fast they move. Calculating the speed of a tsunami is actually quite simple. You just multiply the depth of the ocean – 13,000 feet (4,000 meters) on average – by gravity and take the square root. Doing this, you get an average speed of about 440 miles per hour (700 kilometers per hour). This is much faster than the speed of typical waves, which can <a href="https://www.surfline.com/surf-news/fast-swell-travel/87799">range from about 10 to 30 mph</a> (15 to 50 kph). This equation is what oceanographers use to estimate when a tsunami will reach faraway shores. The tsunami on Jan. 15 hit Santa Cruz, California, 12 hours and 12 minutes after the initial eruption in Tonga. Santa Cruz is 5,280 miles (8,528 kilometers) from Tonga, which means that the tsunami traveled at 433 mph (697 kph) – nearly identical to the speed estimate calculated using the ocean’s average depth. <a href="https://images.theconversation.com/files/441392/original/file-20220118-17-oocmnd.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/441392/original/file-20220118-17-oocmnd.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="A flooded airport runway covered in debris." /></a> Many tsunamis, including the 2011 Tsunami in Japan, move inland and can flood areas far from the coast. <a href="https://commons.wikimedia.org/wiki/File:SendaiAirportMarch16.jpg#/media/File:SendaiAirportMarch16.jpg" class="source">U.S. Air Force photo/Staff Sgt.

What makes tsunamis so much more destructive than normal waves? <a href="https://images.theconversation.com/files/441394/original/file-20220118-19-v4uwmj.gif?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/441394/original/file-20220118-19-v4uwmj.gif?ixlib=rb-1.1.0&q=45&auto=format&w=237&fit=clip" alt="An animation showing waves approaching a shoreline." /></a> As waves approach shore, they get pushed upward by the rising seafloor. <a href="https://commons.wikimedia.org/wiki/File:Propagation_du_tsunami_en_profondeur_variable.gif#/media/File:Propagation_du_tsunami_en_profondeur_variable.gif" class="source">Régis Lachaume via Wikimedia Commons</a>, <a href="http://creativecommons.org/licenses/by-sa/4.0/" class="license">CC BY-SA</a> In the open ocean, tsunami waves can be small and may even be undetectable by a boat at the surface. But as the tsunami approaches land, the ocean gets progressively shallower and all the wave energy that extended thousands of feet to the bottom of the deep ocean gets compressed. The displaced water needs to go somewhere. The only place to go is up, so the waves get taller and taller as they approach shore. When tsunamis get to shore, they often do not crest and break like a typical ocean wave. Instead, they are more like a large wall of water that can inundate land near the coast. It is as if sea level were to suddenly rise by a few feet or more. This can cause <a href="https://www.usgs.gov/special-topics/water-science-school/science/tsunamis-and-tsunami-hazards">flooding and very strong currents</a> that can easily sweep people, cars and buildings away. Luckily, tsunamis are rare and not nearly as much of a surprise as they once were. There is now an extensive array of bottom pressure sensors, called <a href="https://nctr.pmel.noaa.gov/Dart/">DART buoys</a>, that can sense a tsunami wave and allow government agencies to <a href="https://www.noaa.gov/explainers/us-tsunami-warning-system">send warnings</a> prior to the arrival of the tsunami. If you live near a coast – especially on the Pacific Ocean where the vast majority of tsunamis occur – be sure to <a href="https://www.ready.gov/sites/default/files/2020-03/tsunami-information-sheet.pdf">know your tsunami escape route</a> for getting to higher ground, and listen to tsunami warnings if you receive one. The eruption of the Hunga Tonga-Hunga Ha’apai volcano severed the main communication cable that connects the people of Tonga to the rest of the world. While the science of tsunamis can be fascinating, these are serious natural disasters. Only a <a href="https://www.bbc.com/news/world-asia-60039617">few deaths have been reported</a> so far from Tonga, but many people are missing and the true extent of the damage from the tsunami is still unknown.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important; text-shadow: none !important;" src="https://counter.theconversation.com/content/175213/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/sally-warner-1179849">Sally Warner</a>, Assistant Professor of Climate Science, <a href="https://theconversation.com/institutions/brandeis-university-1308">Brandeis University</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Second wave: Coronavirus spreading faster than ever

<div class="post_body_wrapper"> <div class="post_body"> <div class="body_text "> World Health Organisation Director-General Tedros Adhanom Ghebreyesus said that the coronavirus pandemic is "accelerating" and more than 150,000 cases were reported on the 19th of June. In a media briefing, Ghebreyesus said that nearly half of the newly reported cases were from the Americas, with a significant increase from South Asia and the Middle East. "We are in a new and dangerous phase," he explained. "Many people are understandably fed up with being at home (and) countries are understandably eager to open up their societies." He warned that the virus is still "spreading fast" and that measures such as social distancing, mask-wearing and hand washing are still critical. "We have a shared duty to everything we can to prevent, detect and respond to the transmission of COVID-19 detected among refugees in hospitals." On the 22nd of June, the WHO reported that there have been more than 183,000 new cases in the last 24 hours around the world. Brazil had a shocking 54,771 new set of cases and the US followed behind with 36,617 new cases. In Australia, Victoria is bracing for a spike in COVID-19 cases meaning that a second wave of the virus is a "distinct possibility". Victoria confirmed a total of 160 new cases over the past week. </div> </div> </div>

Fears of intense second COVID-19 wave as China reports new cases

<div class="post_body_wrapper"> <div class="post_body"> <div class="body_text "> A new cluster of cases in Beijing, China has sparked worldwide concern as the country has just recorded its highest daily number in two months. Over the weekend, Beijing’s largest seafood and produce market was closed down and the surrounding neighbourhoods were placed into lockdown after more than 50 people tested positive for coronavirus. According to the Beijing health commission, nearly every one of the 53 people who tested positive had worked or shopped at the Xinfadi market. Officials in Fengtai, which is home to more than 2 million people, announced that the district had established a “wartime mechanism” to deal with the fresh wave as police cars patrol the streets and plans for first, second and third grade students to return to school have been immediately suspended. Similar outbreaks have also been reported in Iran and Italy, two countries that were among the worst-hit by the virus. Iran reported more than 100 new virus deaths in a single day for the first time in two months, and Rome reported 109 infections with 5 deaths and 15 new cases detected in a building of squatters. “It means the virus hasn't lost its infectiousness, it isn’t weakening … we shouldn’t let down our guard,” World Health Organisation deputy director Ranieri Guerra told Italian journalists. </div> </div> </div>

Will there be a second coronavirus wave?

More countries have planned to ease coronavirus restrictions, but scientists are wary about how the second wave of the pandemic will impact the world. According to Peter Marks, director of the US Food and Drug Administration’s Center for Biologics Evaluation and Research, “it’s unfortunately not unlikely that we may see a second wave or even a third wave” until a vaccine is discovered. Questions are being considered as research into the virus continues. Can you get COVID-19 more than once? It is still not known if people who had been infected with COVID-19 would develop immunity. Due to the newness of the disease, there is no solid data on the survivors’ immunity, <a href="https://www.msn.com/en-au/news/world/when-will-a-second-wave-of-the-coronavirus-hit-and-what-will-it-look-like/ar-BB12TRVN?li=AAgfYrC">USA Today</a> reported. While some studies suggest that <a href="https://theconversation.com/coronavirus-what-causes-a-second-wave-of-disease-outbreak-and-could-we-see-this-in-australia-134125">reinfection is uncommon</a>, more data is needed to figure out how long immunity might last. What will the second wave look like? Countries previously praised for their success in containing coronavirus, such as Japan and Singapore, have seen a rise in the number of new confirmed cases in recent weeks. “We will not get rid of the disease until every country has a system to detect the disease and stop it near the origin, as or as close to the origin as possible, before it spreads,” Olga Jonas, a senior fellow at the Harvard Global Health Institute told <a href="https://www.vox.com/2020/4/17/21213787/coronavirus-asia-waves-hong-kong-singapore-taiwan">Vox</a>. Gabriel Leung, an infectious disease epidemiologist and dean of medicine at the University of Hong Kong, wrote on the<a href="https://www.nytimes.com/2020/04/06/opinion/coronavirus-end-social-distancing.html"> New York Times</a> that loosening and tightening the epidemic response might be the key. “To see us through the next year or more, we must all prepare for several cycles of a ‘suppress and lift’ policy – cycles during which restrictions are applied and relaxed, applied again and relaxed again, in ways that can keep the pandemic under control but at an acceptable economic and social cost,” Leung wrote. Professor Rob Moodie from the Melbourne School of Population Health at the University of Melbourne said countries need to be careful in maintaining social distancing measures. “We’re going to get in a situation … [where we have to look at] the balance between is the cure worse than the disease? And that is the ultimate dilemma that we’re facing right now,” Professor Moodie told the <a href="https://www.abc.net.au/news/2020-04-09/is-asia-about-to-be-hit-by-another-wave-of-coronavirus-infection/12131944">ABC</a>. “What is our end game in any country? When can we start to open things so people can get together again so they can protect their livelihoods? We don’t know that yet.”

Mockery or bad timing? Cruise staff member waves giant fake hand as passengers miss the boat

Whether it was intentional or not, a cruise ship staff member picked an unfortunate moment to pull out a giant fake hand and wave goodbye to spectators watching the ship disembark from the shore. Just as two unfortunate passengers realised their cruise ship was sailing away without them, a crew member decided to wave a fake hand as the pair looked completely helpless on a dock at St Maarten, Netherlands. But nothing could be done, as the only option the tourists had was to figure out a way to get to the next port on their own. <iframe src="https://www.facebook.com/plugins/video.php?href=https%3A%2F%2Fwww.facebook.com%2Fcrucerospuertorico%2Fvideos%2F688479485001630%2F&show_text=0&width=266" width="266" height="476" style="border: none; overflow: hidden;" scrolling="no" frameborder="0" allowtransparency="true" allowfullscreen="true"></iframe> Footage of the unfortunate incident was posted on Facebook, as it shows the Royal Caribbean cruise ship setting sail from the pier in Philipsburg, St. Maarten. Looking at the video, it seems that the couple had missed boarding by just a few minutes. As the phone camera focuses on the distressed duo, it soon shows a crew member on the ship waving around a giant fake hand that has the word “BYE” written on it. It’s possible the action was a result of bad timing, as the intention still remains unclear. Footage also shows other passengers on the cruise noticing the couple, shouting, “They missed it!” to help spread the word.

Prince Louis's first royal wave: All the adorable moments at Trooping the Colour

For a first time ever, Prince George, 6, Princess Charlotte, 4 and Prince Louis, 1 have attended the Trooping the Colour event together as a trio, alongside their parents Prince William and Duchess Kate. This is also the first time we have seen the adorable Prince Louis ticking off another royal milestone, the Buckingham Palace balcony debut. The little royal joined the likes of his older brother and sister in the cheekiest way possible for the event, held in honour of Queen Elizabeth’s birthday. The little Cambridge royal looked dapper in a blue and white outfit as he made his grand debut in the arms of the Duchess of Cambridge. The one-year-old waved excitedly at the crowds of fans and supporters who joined to watch the royal family, until he reached for his dad, Prince William, in which he proceeded to wave at his grandpa, Prince Charles. Princes Charlotte made her grand debut for the Trooping the Colour event in 2016 when she was also a year old. Prince George’s first time was a little later than his younger siblings, who waved to the loving crowds alongside his parents and other family members at nearly two years of age. It is likely royal fans will get to see the Duke and Duchess of Sussex’s first child, Archie, at next year’s Trooping the Colour Parade for the first time. Scroll through the gallery above to see all of the adorable moments from the Cambridge children at this year’s Trooping the Colour Parade.

Frolicking dolphins ride waves and fly high in the air

A pod of dolphins delighted a crowd of people as they flew high into the air, surfing the wake of the boat. The video, recorded off the west Australian coast on Monday, May 15, shows incredible footage of the dolphins leaping into the air. “They were surfing and launching in our cruise vessel’s wake in Mandurah on Saturday afternoon,” a spokeswoman for Mandurah Cruises said. “This behaviour is a common occurrence in Mandurah during the month of May as it is the peak of mating season, newborns are arriving and the salmon run is happening which causes remarkable feeding frenzies.” How incredible is that? Have you been lucky enough to get up close and personal with dolphin? Video credit: Mandurah, Western Australia via Storyful

Cruise ship hit by 9-metre waves

Startling new footage of a terrifying weather event striking a Florida-bound Royal Caribbean cruise ship has emerged, and it has to be seen to be believed. The “hurricane-force storm” produced 9-metre waves, slamming against the ship and even pushing it to a 45-degree angle. Supposed to be a week-long cruise from New Jersey to Florida and the Bahamas, the journey was cut short and passengers refunded due to the 14-hour-long storm, which sent deck chairs flying and wreaking havoc on the ship’s interior. <iframe width="560" height="315" src="https://www.youtube.com/embed/o9waSshoWOc" frameborder="0" allowfullscreen=""></iframe> Questions have been raised as to why the cruise was allowed to go ahead, after the National Weather Service’s Ocean Prediction Centre issued a storm alert four days prior to departure.
