The Role of Family and Teacher Support in Post-traumatic Stress Symptoms Among Palestinian Adolescents Exposed to Community Violence

Extensive research has been conducted in recent decades on the mental health consequences of Palestinians’ exposure to military and political violence. Despite the alarming rates of Palestinian youth exposure to community violence (ECV), there is a serious dearth of research on the effects of this pattern of exposure. The current study focused on the development of post-traumatic stress disorder (PTSD) symptoms among Palestinian adolescents as a result of their ECV. The study also examines the ability of perceived support from family and teachers to moderate the relationship between ECV and PTSD symptoms, and the involvement of demographic and socioeconomic variables in explaining this development. A sample of 1930 Palestinian secondary school students, aged 12–19, from the West Bank and East Jerusalem, answered questionnaires. Data analysis used univariate, bivariate, and multivariate methods, including SEM. The prevalence of PTSD symptoms was predicted by past year ECV, family support, teacher support, residential density, parents’ education, age, and gender. SEM analysis validated additional relationship paths between variables. Results are discussed, suggesting future research with theoretical and practical implications.     

Mind the Gaps: Are Conclusions About Mindfulness Entirely Conclusive?

Mindfulness has emerged as an important construct in the mental health field. Although evidence suggests benefits, it also appears that excitement over the clinical applications of mindfulness has largely suspended concentrated efforts to clarify fundamental elements of the construct. This article explores conceptual confusion and contrasts primary mindfulness‐based techniques before investigating attrition factors, adverse effects of mindfulness practices, and populations contraindicated for mindfulness‐based techniques. Implications for practice are provided.     

The sweetness of surrender: Glucose enhances self-control by signaling environmental richness

According to the ego-depletion account of loss of self-control, self-control is, or depends on, a depletable resource. Advocates of this account have argued that what is depleted is actually glucose. However, there is experimental evidence that indicates that glucose replenishment is not necessary for regaining self-control, as well as theoretical reasons for thinking that it is not depleted by exercises of self-control. I suggest that glucose restores self-control not because it is a resource on which it relies, but because it serves as a signal of environment quality. I suggest that the evidence is better explained by a rival opportunity costs model of self-control than by the ego-depletion account.     

Promise and Ontological Ambiguity in the In vitro Meat Imagescape: From Laboratory Myotubes to the Cultured Burger

In vitro meat (IVM), also known as cultured meat, involves growing cells into muscle tissue to be eaten as food. The technology had its most high-profile moment in 2013 when a cultured burger was cooked and tasted in a press conference. Images of the burger featured in the international media and were circulated across the Internet. These images—literally marks on a two-dimensional surface—do important work in establishing what IVM is and what it can do. A combination of visual semiotics and narrative analysis shows that images of IVM afford readings of their story that are co-created by the viewer. Before the cultured burger, during 2011, images of IVM fell into four distinct categories: cell images, tissue images, flowcharts, and meat in a dish images. The narrative infrastructure of each image type affords different interpretations of what IVM can accomplish and what it is. The 2013 cultured burger images both draw upon and depart from these image types in an attempt to present IVM as a normal food stuff, and as ‘matter in place’ when placed on the plate. The analysis of individual images and the collection of images about a certain object or subject—known as the imagescape—is a productive approach to understanding the ontology and promise of IVM and is applicable to other areas of social life.     

Stereotype threat may not impact women's inhibitory control or mathematical performance: Providing support for the null hypothesis

Underpinned by the findings of Jamieson and Harkins (2007; Experiment 3), the current study pits the mere effort motivational account of stereotype threat against a working memory interference account. In Experiment 1, females were primed with a negative self- or group stereotype pertaining to their visuospatial ability and completed an anti-saccade eye-tracking task. In Experiment 2 they were primed with a negative or positive group stereotype and completed an anti-saccade and mental arithmetic task. Findings indicate that stereotype threat did not significantly impair women's inhibitory control (Experiments 1 and 2) or mathematical performance (Experiment 2), with Bayesian analyses providing support for the null hypothesis. These findings are discussed in relation to potential moderating factors of stereotype threat, such as task difficulty and stereotype endorsement, as well as the possibility that effect sizes reported in the stereotype threat literature are inflated due to publication bias.     

Emotional self-efficacy,conduct problems,and academic attainment: Developmental cascade effects in early adolescence

The study is amongst the first of its kind to utilise developmental cascade modelling in order to examine the inter-relations between emotional self-efficacy, conduct problems, and attainment in a large, nationally representative sample of English adolescents (n = 2414, aged 11 years). Using a 3-wave, longitudinal, cross lagged-design, we tested three cascading hypotheses: adjustment erosion, adjustment fortification, and academic incompetence. A fourth hypothesis considered the role of shared risk. Results supported small effects consistent with the cascade hypotheses, and a small but significant effect was found for shared risk. Strengths and limits of the study are considered alongside a discussion of the implications for these findings.
