Approximately 30% of suicides in New York City are the result of jumping from a height. After describing jumping suicides and jumping sites, we used polychotomous logistic regression to compare the characteristics of suicides by jumping to those of individuals committing suicide by hanging, ingestion, or shooting. Method used was significantly associated with sociodemographics, occupation, and mental health status, even after adjustment for individual access to the means of committing suicide. Our finding of an independent association between personal characteristics and method used provides strong evidence for the hypothesis that controlling access to an agent of suicide can influence overall suicide rates, at least in the short term. Study results support the introduction of preventive programs to control access to commonly employed agents of suicide.  相似文献

This study examined the relationship between viewing an infant DVD and expressive and receptive language outcomes. Children between 12 and 15 months were randomly assigned to view Baby Wordsworth, a DVD highlighting words around the house marketed for children beginning at 12 months of age. Viewings took place in home settings over 6 weeks. After every 2 weeks and five exposures to the DVD, children were assessed on expressive and receptive communication measures. Results indicated there was no increased growth on either outcome for children who had viewed the DVD as compared to children in the control group, even after multiple exposures. After controlling for age, gender, cognitive developmental level, income, and parent education, the most significant predictor of vocabulary comprehension and production scores was the amount of time children were read to.  相似文献

An extensive body of literature has documented the widespread and damaging nature of sexual harassment among Anglo women, but little attention has focused on the experiences of women of color. The current paper begins to address this gap by comparing sexual harassment incidence rates and psychological and work–related outcomes of Hispanic and non–Hispanic White women across varying levels of cultural affiliation. Chi–square tests of association suggest that risk of harassment increases with affiliation to the mainstream U.S. culture, and hierarchical regression analyses suggest that cultural affiliation moderates the relation between sexual harassment and occupational functioning. These provocative findings are discussed in the context of social and economic vulnerability, socio–sexual norms, and cultural background.  相似文献

Development of effective treatments for patients following deliberate self-harm (self-poisoning or self-injury) is a very important element in suicide prevention. The randomized controlled trial (RCT) is the mainstay of evaluation of treatments. In a systematic review of the literature, the effectiveness of treatments based on RCTs was examined and the quality of the RCTs was assessed. Twenty trials were identified, and where possible, these were grouped on the basis of similarities among the types of treatment. In this paper, we examine the methodological aspects of the trials and consider what may be learned that will assist in the design of future studies in this field. The methodological quality of the trials was reasonable, but most trials included too few participants to detect clinically important differences in rates of repeated self-harm. In planning future trials, the following major issues should be addressed: investigators should perform power calculations to determine the number of subjects necessary to detect clinically important effects, provide information on method of randomization and interventions, use standard measures of outcome, and focus on homogeneous subgroups of patients. Improving the methodology of future studies in this field will be essential if sound evidence is to be obtained which can inform effective service provision for deliberate self-harm patients.  相似文献

Seminal work by Knobe, Prasada, and Newman (2013) distinguished a set of concepts, which they named “dual-character concepts.” Unlike traditional concepts, they require two distinct criteria for determining category membership. For example, the prototypical dual-character concept “artist” has both a concrete dimension of artistic skills, and an abstract dimension of aesthetic sensibility and values. Therefore, someone can be a good artist on the concrete dimension but not truly an artist on the abstract dimension. Does this analysis capture people's understanding of cornerstone social categories, such as gender, around which society and everyday life have traditionally been organized? Gender, too, may be conceived as having not only a concrete dimension but also a distinct dimension of abstract norms and values. As with dual-character concepts, violations of abstract norms and values may result in someone being judged as not truly a man/woman. Here, we provide the first empirical assessment of applying the dual-character framework to people's conception of gender. We found that, on some measures that primarily relied on metalinguistic cues, gender concepts did indeed resemble dual-character concepts. However, on other measures that depicted transgressions of traditional gender norms, neither “man” nor “woman” appeared dual-character-like, in that participants did not disqualify people from being truly a man or truly a woman. In a series of follow-up studies, we examined whether moral norms have come to replace gender role norms for the abstract dimension. Implications for the evolution of concepts and categories are explored.  相似文献
