Using a variety of perspectives including public health, criminology, ecology, and developmental psychology, this text reviews the latest research on the causes of youth violence in the nation's schools and communities. In this volume, experts from a range of disciplines use a variety of perspectives, notably those of public health, criminology, ecology, and developmental psychology, to review the latest research on the causes of youth violence in the nation's schools and communities and on school-based interventions that have prevented or reduced it. They describe and evaluate strategies for the prevention and treatment of violence that go beyond punishment and incarceration. The volume offers a new strategy for the problem of youth violence, arguing that the most effective interventions use a comprehensive, multi-disciplinary approach and take into account differences in stages of individual development and involvement in overlapping social contexts, families, peer groups, schools and neighborhoods. This book can be used profitably by school teachers and administrators, scholars, policy makers, and those who work with young people at risk, as well as by the general reader who is concerned with current social problems.
