Rethinking Timing of First Sex and Delinquency

The relation between timing of first sex and later delinquency was examined using a genetically informed sample of 534 same-sex twin pairs from the National Longitudinal Study of Adolescent Health, who were assessed at three time points over a 7-year interval. Genetic and environmental differences between families were found to account for the association between earlier age at first sex and increases in delinquency. After controlling for these genetic and environmental confounds using a quasi-experimental design, earlier age at first sex predicted lower levels of delinquency in early adulthood. The current study is contrasted with previous research with non-genetically informative samples, including Armour and Haynie (2007, Journal of Youth and Adolescence, 36, 141–152). Results suggest a more nuanced perspective on the meaning and consequences of adolescent sexuality than is commonly put forth in the literature.

Bombing Alone: Tracing the Motivations and Antecedent Behaviors of Lone‐Actor Terrorists,,

This article analyzes the sociodemographic network characteristics and antecedent behaviors of 119 lone‐actor terrorists. This marks a departure from existing analyses by largely focusing upon behavioral aspects of each offender. This article also examines whether lone‐actor terrorists differ based on their ideologies or network connectivity. The analysis leads to seven conclusions. There was no uniform profile identified. In the time leading up to most lone‐actor terrorist events, other people generally knew about the offender's grievance, extremist ideology, views, and/or intent to engage in violence. A wide range of activities and experiences preceded lone actors' plots or events. Many but not all lone‐actor terrorists were socially isolated. Lone‐actor terrorists regularly engaged in a detectable and observable range of activities with a wider pressure group, social movement, or terrorist organization. Lone‐actor terrorist events were rarely sudden and impulsive. There were distinguishable behavioral differences between subgroups. The implications for policy conclude this article.     

Carbon‐Based Fingerprint Powder as a One‐Step Development and Matrix Application for High‐Resolution Mass Spectrometry Imaging of Latent Fingerprints

Carbon‐based materials are often used as matrices for matrix‐assisted laser desorption/ionization mass spectrometry (MALDI‐MS) and its imaging (MALDI‐MSI). However, researchers have refrained from using carbon‐based fingerprint powder (CFP) as a matrix due to high background and contamination. In this work, the compatibility of CFP is reevaluated with MALDI‐MSI using a high‐resolution mass spectrometer (HRMS) and compared to traditional organic matrices. Relevant fingerprint compounds were easily distinguished from carbon cluster peaks when using HRMS. For fair comparison, half of a fingerprint was dusted with CFP while the other half was dusted with traditional organic matrices. All compounds studied had comparable, or higher, signal‐to‐noise (S/N) ratios when CFP was used as the matrix. Additionally, chemical image qualities closely followed the trend of S/N ratios. CFP proved to be an effective one‐step development and matrix application technique for MALDI‐MSI of latent fingerprints, when carbon cluster peaks are well separated by a HRMS.     

Youth perceptions of violence in Western Honduras

Abstract

Youth violence is a growing challenge worldwide, particularly in countries that are experiencing extreme social disorganisation. This is exemplified in Honduras which has been one of the top five countries in the world for intentional homicides for over 20 years. While many studies have examined youth violence in urban cities, few have researched youth violence in rural zones. This study presents a case study using social disorganisation theory to investigate the perceptions of 40 youth in rural and peri-urban Santa Rosa de Copán, Honduras, regarding what drives violence and the potential solutions. Consistent with social disorganisation theory, our results demonstrate that youth view violence as an opportunity pathway resulting from economic deprivation, disruptions to the family and neighbourhood, lack of or poorly functioning external agencies and conflicting moral values. There are significant gender differences in the results, with young men pointing to several issues that challenge masculine hegemonic gender norms such as the desire for love and belonging, participation in education and the role of policing.     

From Population Control to Reproductive Rights: Understanding Normative Change in Global Population Policy (1965–1994)

This article examines the process of normative change and nascent norm emergence in areas of global policy making through the convening of UN global conferences. Specifically, the article is a case study of how the norms and discourse undergirding and legitimising global population policy have changed from population control to reproductive rights through the passing decades. The United Nations, as a main site of discursive and normative contestation, provides opportunities for global social movements to lodge oppositional claims against states and other actors in world politics. A constructivist approach is used to identify five processes integral to understanding mutually constitutive and fluid agent-structure processes of normative change and nascent norm emergence in global population policy. This research contributes to the extant constructivist literature on the process of norm emergence by suggesting one processual model that can illuminate other cases of norm formation, maintenance, and change regarding other transnational issues.     

Dosage of treatment to sexual offenders: are we overprescribing?

A sample of 337 offenders who received treatment in a variety of sex offender treatment programs in the Ontario region of Correctional Service Canada between 1993 and 1998 were divided based on the highest intensity sex offender programming that they received (low, moderate, and high). The three groups were compared with reference to a variety of actuarial risk assessment measures, criminogenic factors, and the number and type of treatment programs completed. It was hypothesized that the high-intensity group would have more criminogenic risk factors, higher actuarial scores, and participate in more treatment programs than both the moderate- and low-intensity groups. The results indicate that in general, the hypotheses were supported. Nonetheless, the results suggest that the low-intensity group may be receiving too much sex offender-specific treatment.     

<Emphasis Type="Italic">BodiMojo</Emphasis>: Efficacy of a Mobile-Based Intervention in Improving Body Image and Self-Compassion among Adolescents

Mobile interventions promoting positive body image are lacking. This study presents a randomized controlled evaluation of BodiMojo, a mobile application (app) intervention grounded in self-compassion to promote positive body image. A sample of 274 adolescents, mean (SD) age?=?18.36 (1.34) years, 74% female, were allocated to a control group or used BodiMojo for 6 weeks. Appearance esteem, body image flexibility, appearance comparison, mood, and self-compassion were assessed at baseline, 6, and 12 weeks. Significant time by group interactions emerged for appearance esteem and self-compassion, with appearance esteem and self-compassion increasing in the intervention relative to the control group. These findings provide preliminary support for BodiMojo, a cost-effective mobile app for positive body image.
