The present study examines the quality of peer relations as a mediator between exposure to IPV (intimate partner violence) and internalizing behaviors in a sample of 129 preadolescents and adolescents (ages 10-18), who were interviewed via telephone as part of a multigenerational, prospective, longitudinal study. Relational victimization is also examined as a moderator of IPV exposure on internalizing behaviors. Results demonstrate a significant association of exposure to severe IPV and internalizing behaviors. Relational victimization is found to moderate the effects of exposure to severe IPV on internalizing behaviors. The present findings suggest that the effects of exposure to IPV had a particularly important effect on the risk for internalizing problems if the adolescent also experienced relational victimization. Conversely, the receipt of prosocial behaviors buffer against the effects of IPV exposure on internalizing symptoms in teen girls. 相似文献

Postmortem computed tomography (pmCT) and pmCT angiography (pmCTA) provide a minimally invasive method to determine the cause of death. Postmortem image-guided biopsy allows for precise sampling of histological specimens. This case study describes the findings of lethal systemic fat embolism (FE) on whole-body unenhanced pmCT, pmCTA, and image-guided biopsy, with autopsy and histopathologic correlation. Unenhanced pmCT revealed a distinct fat level on top of sedimented layers of corpuscular blood particles and serum in the arterial system and pulmonary trunk. Subsequent pmCTA showed reproducible results, and image-guided biopsy confirmed fatal FE. pm CT/pmCTA combined with image-guided biopsy established the cause of death as right heart failure as a result of systemic fatal FE prior to autopsy. All imaging findings were consistent with traditional autopsy and histological specimens. This unique case demonstrates new imaging findings in massive, fatal FE and highlights that postmortem imaging, supplemented by image-guided biopsy, may detect the cause of death prior to traditional autopsy. 相似文献

The present study examined psychiatric, physical, and quality-of-life functioning in a sample of 270 women veterans receiving outpatient treatment at a Veterans Affairs medical center. Participants were interviewed regarding their civilian (CSA) and military sexual assault (MSA) histories, and data regarding quality of life and health outcomes were obtained through structured interviews and questionnaires. Women veterans with CSA histories reported significantly poorer physical, psychiatric, and quality-of-life functioning compared to those without a history of sexual assault. Furthermore, women veterans with an MSA history demonstrated additional negative consequences above and beyond the effects of CSA. The study sample was comparable to a national random sample of women veterans who access care in the Veterans Affairs healthcare system, increasing the generalizibility of the results. 相似文献

The minimum postmortem interval can be estimated based on knowledge of the pattern of insect succession on a corpse. To use this approach requires that we take into account the rates of insect development associated with particular climatological conditions of the region. This study is the first to look at insect succession on decomposing carcasses in the high altitude plains (Paramo) in Colombia, at 3035 m above sea level. Five stages of decomposition were designated with indicator species identified for each stage: Callíphora nigribasis at the fresh stage; Compsomyiops verena at the bloated stage; Compsomyiops boliviana during active decay; Stearibia nigriceps and Hydrotaea sp. during advanced decay and Leptocera sp. for dry remains. A succession table is presented for carrion-associated species of the region, which can be used for estimating time since death in similar areas. Compsomyiops boliviana is reported for the first time in Colombia. 相似文献

This article shows how sports contributed to create new experiences and expressions of gender in Argentina in the first half of the twentieth century. The sportswoman embodied a new model of femininity, a novel type of modern, healthy and active womanhood that defied traditional constructions of gender. Sports affected women's experience of gender, providing a site for the development of an emotional and spiritual well-being by fostering personal and psychological qualities like self-esteem, self-satisfaction and self-determination. Participation in sports also helped to redefine how women related to their environment by widening their social circles and relationships. These changes triggered a number of fears and anxieties about sport's potential for gender dis-order. In particular, the figure of the machona, a masculinized, unattractive, and mannish woman, became a symbol of this dis-order. The use of humor, parody, and theatrical displays of gender became ways through which these fears were both expressed and negotiated. 相似文献

The Great Depression affected the Spanish economy, sharply increasing the number of unemployed workers, known as the ‘sin trabajo’. In an effort to address problems with the labour market, the Central Office for Job Placement and Defence against Unemployment was established in 1931 for the purpose, in Niceto Alcalá-Zamora’s words, of heading off ‘regrettable passions and misadventures of a social or political nature’. The ‘reformist challenge’ to the traditional social order would commence that same year, when the PSOE’s Largo Caballero became head of the Ministry of Labour. The staff of the Central Office for Job Placement were aware of proposals by Keynes and other economists regarding this issue, so it can be said that in addition to responding to the urgent social pressure of the moment, the employment policies implemented also sought added legitimacy in the context of theoretical trends that enjoyed consensus at that time. 相似文献
