Shifting Boundaries: An Experimental Evaluation of a Dating Violence Prevention Program in Middle Schools

Abstract: We randomly assigned the Shifting Boundaries interventions to 30 public middle schools in New York City, enrolling 117 sixth and seventh grade classes (over 2,500 students) to receive a classroom, a building, a combined, or neither intervention. The classroom intervention included a six-session curriculum emphasizing the laws and consequences for perpetrators of dating violence and sexual harassment (DV/H), the social construction of gender roles, and healthy relationships. The building-based intervention included the use of building-based restraining orders, higher levels of faculty/security presence in safe/unsafe "hot spots" mapped by students, and posters to increase DV/H awareness and reporting. Student surveys were implemented at baseline, immediately after the intervention, and 6-months post-intervention. As hypothesized, behaviors improved as a result of the interventions. The building-only and the combined interventions were effective in reducing sexual violence victimization involving either peers or dating partners at 6-months post-intervention. This was mirrored by reductions in sexual violence perpetration by peers in the building-only intervention. While the preponderance of results indicates that the interventions were effective, an anomalous result (increase in sexual harassment victimization reports that was contradicted by lower frequency estimates) did emerge. However, after analysis these anomalous results were deemed to be most likely spurious. The success of the building-only intervention alone is important because it can be implemented with very few extra costs to schools.

The Evidence-Based Policing Matrix

Abstract: The next phase of evidence-based policing requires both scholars and practitioners to move from lists of specific studies about “what works” to using that information strategically. This requires developing generalizations or principles on the nature of effective police strategies and translating the field of police evaluation research into digestible forms that can be used to alter police tactics, strategies, accountability systems, and training. In this article, we present a tool intended for such use: the Evidence-Based Policing Matrix. The Matrix is a consistently updated, research-to-practice translation tool that categorizes and visually bins all experimental and quasi-experimental research on police and crime reduction into intersections between three common dimensions of crime prevention—the nature of the target, the extent to which the strategy is proactive or reactive, and the specificity or generality of the strategy. Our mapping and visualization of 97 police evaluation studies conducted through December 31, 2009, indicate that proactive, place-based, and specific policing approaches appear much more promising in reducing crime than individual-based, reactive, and general ones. We conclude by discussing how the Matrix can be used to guide future research and facilitate the adoption of evidence-based policing.

A randomized controlled trial of different policing strategies at hot spots of violent crime

Abstract: Focusing police efforts on “hot spots” has gained acceptance among researchers and practitioners. However, little rigorous evidence exists on the comparative effectiveness of different hot spots strategies. To address this gap, we randomly assigned 83 hot spots of violence in Jacksonville, Florida, to receive either a problem-oriented policing (POP) strategy, directed-saturation patrol, or a control condition for 90 days. We then examined crime in these areas during the intervention period and a 90-day post-intervention period. In sum, the use of POP was associated with a 33% reduction in “street violence” during the 90 days following the intervention. While not statistically significant, we also observed that POP was associated with other non-trivial reductions in violence and property crime during the post-intervention period. In contrast, we did not detect statistically significant crime reductions for the directed-saturation patrol group, though there were non-significant declines in crime in these areas during the intervention period. Tests for displacement or a diffusion of benefits provided indications that violence was displaced to areas near the POP locations, though some patterns in the data suggest this may have been due to the effects of POP on crime reporting by citizens in nearby areas. We conclude by discussing the study’s limitations and the implications of the findings for efforts to refine hot spots policing.

A tale of two cities: Gangs as organized crime groups

Abstract: This article examines the extent to which street gangs are becoming organized crime groups. Active gang members were asked about gang structure and organization, gang activities, and relationships ...

Are Restorative Justice Conferences Effective in Reducing Repeat Offending? Findings from a Campbell Systematic Review

Abstract: This paper synthesizes the effects on repeat offending reported in ten eligible randomized trials of face-to-face restorative justice conferences (RJCs) between crime victims, their accused or convicted offenders, and their respective kin and communities. After an exhaustive search strategy that examined 519 studies that could have been eligible for our rigorous inclusion criteria, we found ten that did. Included studies measured recidivism by 2 years of convictions after random assignment of 1,880 accused or convicted offenders who had consented to meet their consenting victims prior to random assignment, based on “intention-to-treat” analysis. Our meta-analysis found that, on average, RJCs cause a modest but highly cost-effective reduction in the frequency of repeat offending by the consenting offenders randomly assigned to participate in such a conference. A cost-effectiveness estimate for the seven United Kingdom experiments found a ratio of 3.7–8.1 times more benefit in cost of crimes prevented than the cost of delivering RJCs. RJCs are a cost-effective means of reducing frequency of recidivism.
