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

Using a sample of 781 adolescents (ages 13–17, 52.8% male) from a community survey, this study examined gender differences
in the co-occurrence of specific anxiety disorders with substance use in adolescents. The associations between anxiety disorders
and substance use differed according to the particular anxiety disorders and forms of substance use being examined, as well
as by gender. Social phobia was associated with cigarette smoking among boys only. For girls, social phobia appeared to be
negatively associated with drug use. For the other anxiety disorders, the associations with substance use tended to be stronger
among girls. These findings highlight the need to improve clinical recognition of the anxiety disorders and to improve treatment
access for afflicted adolescents. Future studies based on longitudinal data could further elucidate the relationships among
anxiety disorders, gender, and substance use. 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

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
