Can At-Risk Youth Be Diverted From Crime?: A Meta-Analysis of Restorative Diversion Programs

Existing reviews of the impact of restorative justice programs on juvenile recidivism have reached mixed conclusions. The present meta-analysis identified relevant studies through a systematic search of 20 databases over a 25-year period as well as the ancestry method. Application of inclusion criteria resulted in a set of 21 studies contributing 21 independent effect sizes. Programs were found to be overall effective at reducing recidivism, with a pooled odds ratio of 1.28. Subgroup analyses indicate strong evidence that study and treatment characteristics play a role in evaluation results, such as strength of research design and racial/ethnic mix of program participants. Overall quality of the literature is relatively weak, with the large majority of studies derived from non-peer-reviewed sources and a lack of detail presented on treatment characteristics. Limitations with respect to exclusion criteria, sample sizes, and between-study heterogeneity are discussed.

Do Sex Offenders Have Higher Levels of Testosterone? Results From a Meta-Analysis.

The purpose of the current study is to review the available scientific evidence on the relationship between testosterone and sexual aggression. A systematic search for all primary studies comparing basal testosterone levels in sex offenders and non-sex offenders was undertaken across 20 electronic databases using an explicit search strategy and inclusion/exclusion criteria. A total of seven studies were identified and 11 effect sizes were computed; effects were pooled using both fixed and random effects meta-analysis models. Although individual study findings present a mix of results wherein sex offenders have higher or lower baseline levels of testosterone than non-sex offenders, pooled results indicate no overall difference between groups. Moderators of the analyses suggest possibly lower rates of testosterone in child molesters than controls; however, results are dependent on study weighting. Limitations, policy implications with respect to chemical castration laws, and future directions for research are discussed.

Promises kept? A meta-analysis of gang membership prevention programs

Purpose – The purpose of this paper is to synthesize the effects of gang prevention programs on gang membership. Design/methodology/approach – The authors conducted a systematic literature review across 19 bibliographic databases and a meta-analysis of the effectiveness of these strategies. Findings – The database search resulted in 3,850 hits. Of the 162 studies that were screened in full, six involved a prevention program with outcomes commensurate for meta-analysis. Pooled log odds ratios indicate a significant, positive effect of gang prevention programs at reducing gang membership; however, sensitivity analysis demonstrates that the results are driven by the effects of a single study. Originality/value – Despite the small sample size, the current study presents the best available evidence regarding the effectiveness of gang membership prevention programs. There is a critical need in the field of gang control for rigorous evaluation of prevention strategies.

Getting in People’s Faces: On the Symbiotic Relationship between the Media and Police Gang Units

ABSTRACT The current study explores the relationships among high-profile homicide incidents, media representations of gang homicides, and the establishment of specialized police task forces in British Columbia, Canada. The sample includes all articles on homicide published between 2004 and 2010 in a major daily newspaper (N = 2,873). We examine the attention given to gang-related homicides compared to other homicides, explore the impact of high-profile shootings on trends in reporting, and discuss the timing of media reports in relation to the creation of specialized police forces. Results are discussed with respect to the symbiotic relationship between police organizations and the media.

Familiar Gangsters: Gang Violence, Brotherhood, and the Media’s Fascination With a Crime Family:

Media reports can have a significant and lasting impact on public perceptions about crime and criminals. Jonathan, Jarrod, and Jamie Bacon gained notoriety in Vancouver through substantial media coverage for their involvement in gang-related shootings and criminal activity. The present study examines how the media have portrayed the Bacon brothers and their importance in the region’s gang scene. We examine all articles published in the area’s largest newspaper, the Vancouver Sun, mentioning the Bacon family between 2008 and 2015 (N = 401). Specifically, we explore the media’s depiction of the Bacons through developing a thematic content analysis, with themes tested in a keyword analysis using a corpora comparison with a set of reference articles. We argue that the Bacon brothers’ family relationship, tumultuous gang alliances, and alleged involvement in Vancouver’s worst gang-related shooting led to the media overreporting and sensationalizing their criminal activity and prominence in the local gang landscape. In addition, we contend that the popular theme of crime families provided the media with a narrative that proved useful in a context where the police and the courts were simultaneously trying to adapt to the emerging reality of violent gang conflict.
