Book excerpt: From concerns about juveniles' incorrigibility at the turn of the century to school violence in the 1990s, adults have attempted to understand, control, and prevent juvenile violence. Yet, juvenile violence takes many forms, including both violence by juveniles and violence against juveniles, and has various causes and consequences. Since juvenile violence cannot be understood without examining the social context of a given time, this comprehensive encyclopedia provides a historical overview of many significant time periods and offers entries about many types of juvenile violence. It covers competing theories of youth violence; issues such as gender, race, and educational status; and the criminal justice system's methods for dealing with both victims and offenders over time. Additionally, several topics that receive little attention in traditional volumes about juvenile violence, such as hazing, systemic violence in schools, peaceable schools, are covered in these pages. Each entry utilizes current sources, making the book as up-to-date as possible. The front and back matter offer important information, including a chronological list of significant events related to juvenile violence and book and Web resources. Authors represent many different fields, including Sociology, Psychology, Education, History, Social Work, Political Science, Policing, and English. This offers readers a diversity of perspectives and information from a variety of sources. Confronting a difficult and often-misunderstood subject, this encyclopedia is essential to a better understanding of juvenile violence.
