Mentoring programs to affect delinquency and associated outcomes of youth at risk: A comprehensive meta-analytic review

Objectives

To conduct a meta-analytic review of selective and indicated mentoring interventions for effects for youth at risk on delinquency and key associated outcomes (aggression, drug use, academic functioning). We also undertook the first systematic evaluation of intervention implementation features and organization and tested for effects of theorized key processes of mentor program effects.

Methods

Campbell Collaboration review inclusion criteria and procedures were used to search and evaluate the literature. Criteria included a sample defined as at risk for delinquency due to individual behavior such as aggression or conduct problems or environmental characteristics such as residence in a high-crime community. Studies were required to be random assignment or strong quasi-experimental design. Of 163 identified studies published from 1970–2011, 46 met criteria for inclusion.

Results

Mean effects sizes were significant and positive for each outcome category (ranging from d?=?0.11 for academic achievement to d?=?0.29 for aggression). Heterogeneity in effect sizes was noted for all four outcomes. Stronger effects resulted when mentor motivation was professional development but not by other implementation features. Significant improvements in effects were found when advocacy and emotional support mentoring processes were emphasized.

Conclusions

This popular approach has significant impact on delinquency and associated outcomes for youth at risk for delinquency. While evidencing some features may relate to effects, the body of literature is remarkably lacking in details about specific program features and procedures. This persistent state of limited reporting seriously impedes understanding about how mentoring is beneficial and ability to maximize its utility.

Maritime Security in East Asia and Prospects for U.S.-China Cooperation

As China and the United States explore how to craft a ＂new type＂ .or ＂new model＂ of bilateral relations, a key challenge will be deepening cooperation on a series of shared security issues. Alongside problems on the Korean Peninsula, cyber security, and other matters, is preserving peace and stability in East Asia＇s maritime regions, especially in the context of ongoing disputes in the Yellow, East China, and South China seas.     

Use of Craniofacial Superimposition in Historic Investigation

A skeleton discovered in Grand Forks, North Dakota was purported to belong to Clelland “Clell” Miller, a James‐Younger gang member, who was killed during the Northfield Bank robbery on September 7, 1876. A 3‐D image from a computer tomography (CT) scan of the skull was obtained, and a craniofacial superimposition was conducted to determine if the skull could belong to Miller. The superimposition method used in this case was to overlay the CT image of the skull onto Miller's postmortem photograph. In addition to the craniofacial superimposition, the images were juxtaposed to compare similarities or differences in facial morphology between the skull and photograph. Superimposition methods can be used to exclude identifications; however, they should not be used as a conclusive method for identification. In this case, there were sufficient similarities between the skull and Miller's photograph; therefore, the skull could not be eliminated as possibly being that of Miller.     

China–Taiwan diplomatic competition and the Pacific Islands

Abstract

China and Taiwan have become important actors in South Pacific affairs due to their diplomatic rivalry. Securing the diplomatic recognition of the Pacific Islands countries is expensive for China and Taiwan. There are limits to what the rivals are willing to spend, and they attempt to reduce costs. This dynamic shapes how Taiwan and China engage Pacific Islands politicians. It also motivates their high level official visits to the region, and how they engage South Pacific regional organizations. Despite criticisms that China–Taiwan rivalry corrupts and destabilizes the South Pacific, the issue of whether China and Taiwan's diplomatic rivalry has been beneficial or detrimental to the region remains contentious. China and Taiwan appear to have recently called a truce in their decades-old rivalry. This tacit agreement is still tentative, and the involvement of China and Taiwan in the region has yet to change significantly. However, Taiwan has reportedly begun to reduce funding, and is likely to reform its aid delivery in order to satisfy demands from the South Pacific region's dominant power, Australia, and to improve its image as a humanitarian aid donor. China is also likely to reduce funding while the truce holds. However, China considers its ties with South Pacific governments more important than responding to Australian pressure, and is unlikely to reform its South Pacific aid programmes as a result of the diplomatic truce.

Defending the scientific foundations of the firearms and tool mark identification discipline: responding to recent challenges

Recent challenges have brought the discipline of firearms and tool mark identification to the forefront in recent court cases. This article reviews those challenges and offers substantial support for the scientific foundations of the firearms and tool mark identification discipline. A careful review of the available literature has revealed that firearms and tool mark identification is rooted in firm scientific foundations, critically studied according to the precepts of the scientific method culminating in the Association of Firearms and Toolmark Examiners' Theory of Identification. Firearms and tool mark identification has been validated in a manner appropriate for evidence of the kind to be expected in firearms and tool mark examinations. Proficiency tests and error rates have been studied and can provide consumers of the disciple with a useful guide as to the frequency with which misidentifications are reported in the community using appropriate methodologies and controls. As a result, the primary issues in recent challenges do not invalidate the firearms and tool mark discipline as a science nor should it detract it from its admissibility in a court of law.     

Risk Terrain Modeling and Socio-Economic Stratification: Identifying Risky Places for Violent Crime Victimization in Bogotá, Colombia

This research focused on the effect of the built environment on Bogotá’s violent crime by using the Risk Terrain Modeling (RTM) technique. The current study used 17 ecological variables, including micro-level data on the spatial distribution of socio-economic strata, and the location of an array of businesses and other features of the landscape. As suggested by the results of this study, the spatial distribution of violent crime in Bogotá is highly correlated with the allocation of socio-economic strata throughout its geography. A statistically valid RTM analysis identified the micro-level risk factors associated with three types of violent crime incidents, namely homicide, assault, and theft incidents. These results suggest that future violent crime incidents are more likely to occur at a reduced number of high-risk micro-places. Moreover, while homicide and assault incidents were more likely to cluster within the poorest areas of the city, theft incidents presented a higher risk of victimization near the city center, where economic activity and suitable targets concentrate. This study offers a unique account regarding the effect of socio-economic segregation on violent crime victimization across Bogotá’s geography and within different socio-economic strata classifications.
