This volume addresses these key issues through an analysis of important theoretical debates on issues such as digital democracy, cultural politics and transnational communities. Featuring contributors from both sides of the Atlantic, the book contains a series of case-studies on new social movements including campaigns on the environment, gender, animal rights and human rights. It combines cutting edge research with theoretical material and makes an important contribution to this highly topical and rapidly growing area. This book will be invaluable reading for students in areas including Politics, Communications and IT, Sociology and Cultural Studies.
