The Pembroke Center for Teaching and Research on Women presents a discussion titled "Vulnerable Families in the (Un)Changing Economy," as part of Family Weekend. Anna Aizer, professor of economics and public policy at Brown University, and Drew Walker, Pembroke Center associate director and director of gender and sexuality studies, will engage in a conversation about Aizer's research, which explores how gender and other issues of difference may influence labor, health and the "intergenerational transmission of poverty." The event begins at 4 p.m. in Pembroke Hall, Room 305, 172 Meeting St.
