A sociologist and psychologist, each familiar with the other's discipline, make a case for the adoption of an interdisciplinary perspective in the future development of criminology. The inadequacy of any single approach, whether sociological or clinical, to research design, the collection and evaluation of data, and theory construction in so complex an area is revealed in a worldwide survey of trends in this field during this century. The approach proposed is demonstrated by an analysis of violence, particularly homicide. To provide an instrument for the central focus of the presentation, the subculture of violence is developed as a theoretical framework, and this is reinforced by rigorous analysis of a set of key concepts: subculture, roles, norms, and values. The phenomena of aggression and violence are then explored in their biological, psychological, psychiatric, and sociological aspects. Finally, problems of control, prevention, and treatment of the violent offender are discussed, and suggestions are offered for future research in the subculture of violence. A comprehensive survey and analytical discussion are provided for studies dealing with aggression, violence, and homicide, supported by a bibliography with 134 listings. A subject index is also provided. (Publisher abstract modified)
