 Social Movements.Inspired by James M. Jasper's cultural work in the late 1990s, especially The Art of Moral Protest, a number of scholars of protest and social movements have begun to examine the emotions involved.They include Erika Summers Effler, a student of Randall Collins who examines how emotions inform a sense of time in Laughing Saints and Righteous Heroes; Lynn Owens, who documents the emotions of a declining social movement, Amsterdams's squatters, in Cracking under Pressure; and Verta Taylor, whose book, Rock-a-Bye Baby documents struggles over the feelings new mothers are supposed to feel.
