The Adolescent Brain Cognitive Development – Social Development Study (ABCD-SD) is a longitudinal study on the relationship between the developing brain and delinquency and victimization. Supplementing ABCD brain and cognitive development measures, ABCD-SD protocol measures a wide array of delinquency- and victimization-related risks, protective factors and outcomes. These presentations will describe early adolescent findings from ABCD-SD on delinquency and victimization.

Ohio State University Since World War II, the homicide rate in the U.S. has been three to ten times higher than in Canada, Western Europe, and Japan. This, however, has not always been the case. What caused the dramatic change? Dr. Roth discussed how and why rates of different kinds of homicide have varied across time and space over the past 450 years, including an examination of the murder of children by parents or caregivers, intimate partner violence, and homicides among unrelated adults.

Research tells us that a relatively small fraction of individuals experience a large proportion of violent victimizations. Thus, focusing on reducing repeat victimization might have a large impact on total rates of violence. However, research also tells us that most violent crime victims do not experience more than one incident during a six-month or one-year time period. As a result, special policies to prevent repeat violence may not be cost-effective for most victims.

Bill King discusses the operations of the National Integrated Ballistic Information Network (NIBIN), a program through which firearms examiners at state and local crime laboratories compare tool marks on fired bullets or cartridges found at a crime scene to digitized images of ballistic evidence in a nationwide database.

The NIJ-sponsored Expert Working Group on Human Factors in Latent Print Analysis is clarifying potential sources of error in pattern recognition analysis. It will develop best practices to remove or minimize these sources. NIJ is addressing recommendations in the 2009 National Academy of Sciences' report titled "Strengthening Forensic Science in the United States: A Path Forward." Specifically, the panelists focus on recommendation 5, which encourages research programs on human observer bias and sources of human error in forensic examinations.

This Research for the Real World seminar explores common police practices for responding to gun violence and the extent to which they are contributing to reductions in violent incidents. The panel will also explore the role of multi-disciplinary partners such as the public health sector in reducing gun violence, and discuss promising practices for law enforcement partnerships to leverage complimentary violence reduction efforts.
