Resilience and Vulnerability in Adolescents: Genetic Influences on Differential Response to Risk for Delinquency

Prior research has identified a vast number of correlates for delinquent behavior during adolescence, yet a considerable number of errors in prediction remain. These errors suggest that behavioral development among a portion of youths is not well understood, with some exhibiting resilience and others a heightened vulnerability to risks. Examining cases that do not confirm prediction outcomes provides an opportunity to achieve a greater understanding of the relationships between risk factors and delinquency, which can be used to improve theoretical explanations of behavior. This study explores the contribution of genetic and environmental factors to differences in individual responses to cumulative risk for delinquency among a sample of adolescent twins (N = 784 pairs, 49 % female) in the National Longitudinal Study of Adolescent Health. The results indicate that additive genetic and unique environmental factors significantly contribute to variation in responses to cumulative risk across 14 risk factors spanning individual, familial, and environmental domains. When analyzed separately, the majority of the difference between vulnerable youths and the overall population was attributed to genetic influences, while differences between resilient youths and the population were primarily attributed to environmental influences. The findings illustrate the importance of examining both genetic and environmental influences in order to enhance explanations of adolescent offending.     

Peer Influence and Context: The Interdependence of Friendship Groups,Schoolmates and Network Density in Predicting Substance Use

This article focuses on the degree to which friends’ influence on substance use is conditioned by the consistency between their behavior and that of schoolmates (individuals enrolled in the same school, but not identified as friends), contributing to the literature on the complexity of interactive social influences during adolescence. Specifically, it hypothesizes that friends’ influence will diminish as their norms become less similar to that of schoolmates. The authors also propose that this conditioning relationship is related to the density of the friendship group. This study uses data from the National Longitudinal Survey of Adolescent Health (AddHealth) (n ~ 8,000, 55 % female) to examine the interactive relationship between friend and schoolmate influences on adolescent substance use (smoking and drinking). The sample contains students ranging from age 11 to 22 and is 60 % White. The findings demonstrate that, as the substance use of the friendship group becomes more dissimilar from schoolmates’ substance use, the friendship group’s influence on adolescent substance use diminishes. Further, the results demonstrate that this conditioning relationship does not emerge when the friendship group is highly dense.     

Intragroup Contact and Anxiety Among Ethnic Minority Adolescents: Considering Ethnic Identity and School Diversity Transitions

Everyday interactions with same-racial/ethnic others may confer positive benefits for adolescents, but the meaning of these interactions are likely influenced by individual differences and larger structural contexts. This study examined the situation-level association between contact with same-ethnic others and anxiety symptoms among a diverse sample of 306 racial/ethnic minority adolescents (Mage = 14 years; 66 % female), based on (1) individual differences in ethnic identity centrality and (2) developmental histories of transitions in diversity between elementary, middle, and high school. The results indicated that at the level of the situation, when adolescents interacted with more same-ethnic others, they reported fewer anxiety symptoms. Further, for adolescents who had experienced a transition in school diversity, the positive benefits of contact with same-ethnic others was only conferred for those who felt that their ethnicity was very important to them. The importance of examining individual differences within larger developmental histories to understand the everyday experiences of ethnic minority adolescents are discussed.     

The peasants in turmoil: Khmer Rouge,state formation and the control of land in northwest Cambodia

Over the past 15 years, northwest Cambodia has seen dramatic agrarian expansion away from the central rice plain into the peripheral uplands fuelled by peasant in-migration. Against this background, we examine the nature of relations between the peasantry and the state. We first show the historical continuities of land control processes and how the use of violence in a post-conflict neoliberal context has legitimised ex-Khmer Rouge in controlling land distribution. Three case studies show the heterogeneity of local level sovereignties, which engage the peasants in different relations with authority. We examine how these processes result in the construction of different rural territories along the agricultural frontier and argue that, in this region of Cambodia, the struggles between Khmer Rouge and neoliberal modes of land control are central to state formation processes.     

Nothing Special? Propaganda and Women's Roles in Late First World War Britain

Women's roles and work did not dramatically change during the First World War; their contributions as citizens simply received greater recognition. This article explores women's roles as subjects, objects and producers of National War Aims Committee propaganda in Britain during 1917–18. It examines differing representations of, and outlines the production of, ‘special’ propaganda for women, discussing women's interactions with and employment by the Committee. Finally, it analyses a series of articles which mixed patriotic rhetoric, practical domestic tips and observations on women's ‘new’ work. Far from uncritically accepting their ‘special’, separate place, the evidence suggests that women, as both objects and producers of propaganda, engaged with it on their own terms as British citizens.     

Further Pseudo-Operational Trials with the Lumicyano Double- and Co-Fuming Process for the Detection of Latent Fingermarks

This study presents a number of pseudo-operational trials on plastic bags investigating the double- and co-fuming process of a one-step fluorescent cyanoacrylate (Lumicyano^TM) in comparisons with the two-step process with basic yellow 40 (BY40) staining for the detection of latent fingermarks. The results demonstrate that both Lumicyano solution and dye contribute to the increased detection of latent fingermarks during the double-fuming process (trial 1). Co-fuming the Lumicyano solution and dye separately (at a concentration of 8%) but simultaneously was less effective than 8% Lumicyano (trial 2). Co-fuming Lumicyano 8% and an additional 8% Lumicyano dye by weight was more effective than Lumicyano 8% (trial 3), possibly due to increased fluorescent material deposition during co-fuming allowing for better visualization. The use of BY40 after Lumicyano resulted in a considerable increase in detected fingermarks.     

MI Implementation in Juvenile Justice: A Case Report

Motivational interviewing (MI) is a communication style focused on enhancing clients’ own motivation towards change. In the justice system MI has evidence to support that it enhances communication and change behaviors in youth. As most MI training is designed for healthcare settings training and implementation of MI must be adapted to fit the juvenile justice model. This includes both rehabilitation and restorative justice. Here we describe the details that allowed one county small county in Pennsylvania to roll out MI training and initial skills review in less than 6 months. The case reviews the details of planning, trainings, and timing of activities. We then discuss what elements of those details fit into a greater implementation plan that may be applied elsewhere. Four key elements were instrumental to implementation: 1) appreciation of JPO time constraints, 2) cost containment 3) using blending to enhance JPO flexibility with MI use, and 4) policies that normalize use of MI. This outline may assist other courts in their own implementation efforts.     

The Effects of Blaming Others for Legislative Inaction on Individual and Collective Evaluations

Legislators commonly blame others for gridlock. We posit that legislators may engage in this type of rhetoric to minimize the individual reputational risks associated with legislative inaction or to boost the relative standing of their party. In a series of six survey experiments, we find that blaming others for inaction undermines voters’ evaluations of individual legislators who engage in this rhetorical strategy. This effect is particularly pronounced among out-partisans and independents. However, blaming rhetoric can also enhance the standing of the blamer’s party relative to the opposing party across all groups (including out-partisans), in large part by undermining the reputations of these other actors. Ultimately, we show that when an individual legislator engages in blaming rhetoric, the immediate net electoral effects are null. This suggests that coordinated efforts by a party to blame opponents may improve the party’s relative standing, while imposing few costs on those engaged in blaming.
