An examination of the place and role of voluntary organisations dedicated to the promotion of peace and the resolution of intractable social conflicts, this work focuses on the work of nongovernmental organisations in Northen Ireland, South Africa, and Israel/Palestine. We highly recommend the Gidron, Katz and Hasenfeld book. This is a systematic, theory-based study of third sector organizations, which have very rarely been studied before. This study contributed significantly to the understanding of their structure and dynamics.
