The book is a comparative study of professional practice to two schools of thought in the field of nonviolent conflict intervention: conflict resolution and conflict transformation. The research relies upon a thorough review of scholarly literature related to these two schools and on primary data collected from twenty semi-structured interviews with professional practitioners. The central question that guided the guided was: Do practitioners'' definition and theories of practice, including goals, intervention strategies, and criteria for success, depend upon their self-identification with either the conflict resolution or conflict transformation school of thought? Categories of analysis for self definitions and intervention strategies arose from practitioner reports. Data related to goals for success were plotted on a framework for evaluating interactive conflict resolution which provided a structure for comparison.The research is relevant to everyone interested in research on practice, It will be of special interest to all those in the evolving field of nonviolent conflict intervention where tensions related to professional identity are part if the current discourse in the field.
