'Jessica Rich breaks new ground in the study of the conditions under which social movements can endure and work with state institutions to advance their policy goals. Her study of the interaction between AIDS activists and bureaucrats in Brazil challenges much of the conventional wisdom about the political impact of social movements and their relations to the state. This is a rare book that promises to change the way scholars think about state-civil society relations and the politics of social policy reform.' Kenneth M. Roberts, Richard J.
