Preventing Bullying Through Science, Policy, and Practice
Bullying has long been tolerated as a rite of passage among children and adolescents. There is an implication that individuals who are bullied must have “asked for” this type of treatment, or deserved it. Sometimes, even the child who is bullied begins to internalize this idea. For many years, there has been a general acceptance and collective shrug when it comes to a child or adolescent with greater social capital or power pushing around a child perceived as subordinate. But bullying is not developmentally appropriate; it should not be considered a normal part of the typical social grouping that occurs throughout a child’s life. Recognizing that bullying behavior is a major public health problem that demands the concerted and coordinated time and attention of parents, educators and school administrators, health care providers, policy makers, families, and others concerned with the care of children, this report evaluates the state of the science on biological and psychosocial consequences of peer victimization and the risk and protective factors that either increase or decrease peer victimization behavior and consequences. | Learn More |

Wanted on Warrants: The Fugitive Safe Surrender Program
Since 2005, the Fugitive Safe Surrender (FSS) program has been implemented in more than twenty cities around the country. Tens of thousands of individuals with active warrants for their arrest have voluntarily surrendered to law enforcement in a church or other neutral setting. The sites are transformed for four days into complete justice systems with pretrial-intake, prosecutors, defense attorneys, judges, and probation/parole and community services staff. Author Daniel J. Flannery has gathered information on who turns themselves in, what the warrant is for, how long the warrant has been active, and what happens to the individual. This collaborative initiative between local and federal law enforcement and community faith-based organizations is unique and has proven to be a successful program that is being copied and initiated throughout the country. ‘Wanted on Warrants’ offers valuable insights into what happens during and after an FSS program and will be welcomed by policymakers and practitioners. | Learn More |

The Cambridge Handbook of Violent Behavior and Aggression
This Handbook provides a comprehensive, multidisciplinary examination of the most current research and thinking about the complex issue of violence and violent behavior. The volume examines a range of theoretical, policy, and research issues and provides a comprehensive overview of aggressive and violent behavior. The Handbook also examines violence at multiple levels: individual, family, neighborhood, and cultural, and across multiple perspectives and systems, including treatment, justice, education, and public health. The Handbook represents the most current and up-to-date research from leading experts around the world. | Learn More |

Violence and Mental Health in Everyday Life
Clinical psychologist Daniel J. Flannery reveals the impact of violence and victimization in the lives of children and adolescents from a developmental perspective. His case studies show the significance of these mental health issues for the individual, family, neighborhood, and community. He offers lists of professional networks and support, including web sites and readings related to violence and mental health, creating a valuable resource for parents, teachers, social workers, childcare workers, public health officials, police officers and others who interact every day with young people, to help them understand more about child development and how experiences with violence can affect development and daily life. | Learn More |

Youth Violence: Prevention, Intervention, and Social Policy
Scholars, public officials, and reporters have described the violence of this decade as epidemic as the homicide rate has doubled for adolescents between 1984 and 1994. Current policy to combat youth violence is primarily reactive, focusing on increased punishments and spending millions of dollars each year on incarceration. Providing the latest research on effective prevention and intervention strategies for reducing youth violence, ‘Youth Violence: Prevention, Intervention, and Social Policy’ is a comprehensive resource for dealing with both perpetrators and victims of violence and understanding the risk factors facing youth. It covers results from tested prevention and intervention programs including practical descriptions, core components for success, evaluation findings, costs, and lessons learned from actual implementations. It also covers intervention techniques that teach pro-social behavior to anti-social youth as well as psychopharmacological and neurobiological issues in the treatment of violent youth. It also provides an extensive reference list of over 700 publications and studies, a practical volume with wide audience appeal, including sociologists, criminologists, psychiatrists, psychologists, social workers, educators, counselors, and nurses. | Learn More |

Defending Childhood Initiative
Children’s exposure to violence, whether as victims or as witnesses, is often associated with long-term physical, psychological, and emotional harm. Children exposed to violence are also at a higher risk of engaging in criminal behavior later in life and becoming part of a cycle of violence. In 2010, United States Attorney General Eric Holder launched the Defending Childhood Initiative to address the exposure of America’s children to violence as victims and as witnesses. The Begun Center serves as the evaluation partner for the Cuyahoga County Defending Childhood project. Evaluation activities include identification of appropriate assessment instruments, analysis of screening and pre/post test data for youth receiving trauma-informed care, evaluation of training sessions held for the child-serving agencies in the area, and possible assessment of the effectiveness of a community awareness campaign.

Fugitive Safe Surrender (FSS)
The Fugitive Safe Surrender (FSS) program is a unique, creative, and highly successful initiative that encourages persons wanted for non-violent felony or misdemeanor crimes to voluntarily surrender to the law in a faith-based or other neutral setting. The program was originally managed nationally by the United States Marshals Service and is currently funded and managed through Ohio’s Attorney General’s Office. FSS is a community re-entry program for wanted non-violent offenders and offers individuals with felony and misdemeanor warrants the ability to turn themselves in to law enforcement and have their cases adjudicated in a safe and non-violent environment. The goal of Fugitive Safe Surrender is to reduce the risk to law enforcement officers who pursue fugitives, to the neighborhoods in which they hide, and to the fugitives themselves. Authorized by Congress in July 2006, Fugitive Safe Surrender is believed to be the first program of its kind in the nation. The Begun Center provides evaluation services for the FSS program and has been onsite at over 20 FSS operations since 2006. | View Full Project Overview |
