The Contribution of Organized Youth Sport to Antisocial and Prosocial Behavior in Adolescent Athletes

In this study, we investigated the contribution of organized youth sport to antisocial and prosocial behavior in adolescent athletes. The sample consisted of N=260 male and female soccer players and competitive swimmers, 12 to 18 years of age. Multilevel regression analysis revealed that 8% of the variance in antisocial behavior and 7% of the variance in prosocial behavior could be attributed to characteristics of the sporting environment. Results suggested that coaches who maintain good relationships with their athletes reduce antisocial behavior, and that exposure to relatively high levels of sociomoral reasoning within the immediate context of sporting activities promotes prosocial behavior. These results point to specific aspects of adolescents’ participation in sport that can be used to realize the educational potential of organized youth sport.

A meta-analysis of the effectiveness of individually oriented Cognitive Behavioral Treatment (CBT) for severe aggressive behavior in adolescents

This meta-analysis, including six studies (13 effect sizes) and 164 adolescents, examined the effectiveness of individually oriented treatment (which means that the intervention contained at least an individual component, possibly in combination with group and/or family therapy) with CBT-elements for adolescents with severe aggression problems. A large and homogeneous overall effect size was found (d = 1.139) indicating consistency across studies. The included studies examined the effect of three interventions, namely, mode deactivation therapy (MDT; four studies), stress-inoculation therapy (1), and the cell-phone program (1). This multilevel analysis demonstrated that only few individually oriented interventions have been developed and evaluated, while four of the included studies used a weak research design. Effective individually tailored interventions for youths with severe aggression problems (who are unsuitable for group treatment) are scant. There may be added value if group interventions are supplemented with more individually tailored evidence-based interventions.     

The Compatibility of Fingerprint Visualization Techniques with Immunolabeling

The chemical composition of a fingermark potentially holds a wealth of information about the fingermark donor, which can be extracted by immunolabeling. Immunolabeling can be used to detect specific components in fingermarks; however, to be applicable in the forensic field, it should be compatible with commonly used fingerprint visualization techniques. In this study, the compatibility of immunolabeling with two different fingerprint visualization techniques, magnetic powdering and ninhydrin staining, was investigated on fingermarks deposited on glass and on nitrocellulose membranes. With dermcidin as antigen of interest, immunolabeling was performed successfully on all developed fingermarks. We can conclude that immunolabeling is compatible with magnetic powdering and ninhydrin staining, which can be of great forensic value.     

Temporary Restraining Orders in the Netherlands: A Qualitative Examination of Perpetrator and Victim Views

In 2009, the Netherlands introduced a 10-day temporary restraining order (TRO) intended for adult perpetrators of domestic violence to defuse dangerous situations and to reduce recidivism by combining a legal action with social services. For this study, 18 victims and 10 perpetrators were interviewed about their experiences with the TRO, related professional help, and the influence the TRO had had on their lives. The interviews were transcribed verbatim and subsequently qualitatively analyzed. Most of the victims were positive about the TRO period. Perpetrators were less positive. The vast majority of respondents accepted help during the TRO and were positive about the professionals’ attitudes, but not necessarily about the type of help. Most respondents reported an increase in their wellbeing, new insights, and no or less serious re-assaults by the perpetrator. The results suggest that, in the short term, TROs have a mainly positive effect on both victims and perpetrators.     

Identification of Crystals Forming on Porcine Articular Cartilage: A New Method for the Estimation of the Postmortem Interval

Articular cartilage was examined to determine its decomposition sequence and its potential for assessing the postmortem interval. Scanning electron microscopy of articular cartilage from buried porcine trotters showed the presence of microcrystals on the synovial surface. These orthorhombic pyramidal or “coffin”‐shaped crystals, appeared at 3 weeks (22 days) after interment and disappeared after 6 weeks. The disappearance of these crystals was linked to decompositional changes to the integrity of the synovial joint. The formation and disappearance of these crystals was associated with a pH change at the cartilage surface. Scanning electron microscopy–energy‐dispersive X‐ray (SEM‐EDX) analysis showed that the five main elements contained within these crystals were carbon, nitrogen, oxygen, magnesium, and phosphorous. Such elemental analysis suggested the crystals may be struvite (MgNH₄PO₄6(H₂O)). Bacteria cultured from the cartilage synovial surface produced struvite crystals when grown in suitable media and were identified by DNA analysis to be Comamonas sp.
