Criminology is a dynamic and evolving field of study. In recent decades, the study of the causes, development, prevention, and treatment of juvenile delinquency and adult crime has produced many important discoveries. This volume addresses two questions about crucial topics facing criminology - from causation to prevention to public policy: Where are we now? What does the future hold? Rolf Loeber and Brandon C. Welsh lead a team of more than forty top scholars from across the world to present the future of research, policy, and practice in the discipline.
