For 20 years, Philly Roller Derby skaters, who go by names like Woolly Slammoth, TrailBlazeHer and Reba Smackentire, have jammed and blocked their way around oval skating rinks in the spirit of feminism, anti-racism, body positivity and queer liberation. When the Philly league joined the Women's Flat Track Derby Association in 2005, it was one of the first, following the Texas Rollergirls in Austin and leagues in Portland, Oregon; Chicago; New York; and other cities. The WFTDA, which governs flat-track roller derby, had formed just one year prior with a goal of 'revolutioniz[ing] the role of women in sports.' Primarily organized by women, the association takes an explicitly feminist position and welcomes anyone who is of a 'marginalized gender.' This includes cisgender women as well as all transgender, intersex and two-spirit individuals. Intersex people have chromosomes and/or reproductive organs that do not fit into a binary male or female classification, while two-spirit refers to members of Indigenous cultures who identify as having both a masculine and feminine spirit....

Jude Kelly, chief executive officer and founder of the Women of the World (WOW) Festival, addresses the threat of online misogyny and 'incels' - to men as well as women, on the Forum's Radio Davos podcast, as she talks about her experience starting WOW, men's role in feminism, and progress and regression around attitudes to women across the world. Jude Kelly: I did the festival for its very first year to celebrate the 100th anniversary of International Women's Day, and it was such a hit' Straight away people said, "Oh, I'd love to do this in Baltimore, I'd love to do this Australia'" The girls and women who come - and the boys and men, because many men attend - they might think they're coming to hear one thing that interests them but they're going to bump into something else. And whether that's something as plaintive and difficult as looking at the violence that's enacted on women... or whether it's something completely joyful, like hearing from the first Indian woman surfing champion... All of these stories make up a sense that there's a vitality in the idea of human progress....

There's a black-and-white photo from a 1920s beauty pageant in a gilt frame hanging above the desk in MIT Professor Lerna Ekmekcioglu's office. The Jazz Age image features white flapper girls in white dresses. There's an unsettling commonality among the women in the photo. Across the office, leaning on a wall near the entrance, is a piece of white backing board on which are pasted a series of images. The highly influential feminist publication and women's journal, 'Hay Gin,' and its founder and editor, Hayganush Mark, are at the collage's core, surrounded by images of socially marginalized women. The social and political distance between those pictures is part of a fascinating journey for Ekmekcioglu and her research into a feminism that centers both her Turkish-Armenian heritage and underrepresented women across the globe. Today, Ekmekcioglu, MIT's McMillan-Stewart Associate Professor of History, the director of MIT's Program in Women's and Gender Studies, and a professor since 2011, credits a focus on the work of leading feminists like bell hooks, her investigation of Turkish-Armenian feminism's foundation, connections between those feminists, and scholarship among other members of underserved populations for her continuing education....

As younger adults opt for 'wellness' products, many are practicing alcohol abstinence. Sometimes referred to as 'sober curious,' this trend of often forgoing alcohol has forged public conversations on the health benefits of abstinence. Its leaders not only believed that alcohol abstinence would lead to better health, but they saw it as a way to create a just society. This movement laid a foundation for the successful campaign for an amendment to the U.S. Constitution. Enacted in 1920, the 18th Amendment barred the sale and distribution of alcoholic beverages. Because of the difficulties of legal enforcement, and following a national campaign waged against Prohibition, the amendment was repealed in 1933. That repeal still casts aspersion on how the temperance movement is remembered today. Many Americans see it as a moralistic crusade dominated by religious zealots. However, temperance became an international movement, with many of its leaders being women. Born in 1839, Willard wanted to become a Methodist minister. Instead, she became a teacher, as women could rarely be ordained at the time. Ultimately, she became the first dean of the newly founded Woman's College at Northwestern University....
