Violent Repeat Victimization: Prospects and Challenges for Research and Practice
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.

Opening the Black Box of NIBIN
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.

Human Factors in Latent Print Examination
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.

Funding Opportunities for Publicly Funded Crime Labs, Fiscal Year 2017
This webinar will inform the audience of the changes to three programs available for publicly funded forensic laboratories and introduce a new program for FY 2017. Changes to existing programs will be highlighted and presenters will discuss the background and goals of the solicitations, recommendations for successful applications, application expectations and requirements, the review process, and the application checklist. There will also be time for questions and answers at the end of the webinar.
Solicitations discussed include:

Homicide in the United States
The 2009 NIJ Conference kicked off with a blue-ribbon panel of leaders with expertise in urban issues as they relate to homicide. These experts will discuss promising approaches that have resulted in reduced violence and community empowerment.
Impression Evidence: Strengthening the Disciplines of Pattern and Impression Sciences Through Research
Forensic examinations involving specific forensic science disciplines are typically dependent upon qualitative analyses and expert interpretation of observed patterns based on a scientific foundation, rather than quantitative results. These disciplines include latent fingerprints, questioned documents, footwear, and other forms of impression and pattern evidence.
Physics and Pattern Interpretation
Physics and pattern interpretation refers to a collection of forensic disciplines where the evidence is generated through physical processes. This can range from fingerprints to footwear impressions, striations from a firearm on a bullet, to bloodstains on a surface. Examination of this evidence involves classification or comparison of the spatial arrangement of physical features. The disciplines under physics and pattern interpretation include:
- Firearms and toolmarks...
