OBJECTIVE: To examine family risk factors associated with dissociative symptoms among homeless and runaway youth. METHOD: Three hundred and twenty-eight homeless and runaway youth were interviewed using a systematic sampling strategy in metropolitan Seattle. Homeless young people were interviewed on the streets and in shelters by outreach workers in youth service agencies. RESULTS: The current study revealed widespread prevalence of dissociative symptoms among these young people. Multivariate analyses revealed that sexual abuse, physical abuse, and family mental health problems were all positively associated with dissociative symptoms. No gender differences were found for any of the models. CONCLUSIONS: Dissociative behavior is widespread among these youth and may pose a serious mental health concern. Some young people experience numerous stressors, and with few resources and little support available, many may invoke maladaptive strategies such as dissociative behavior to handle such situations, which may in turn be detrimental to their mental health. Unless youth are provided with programs and intervention, the cycle of abuse that they have experienced at home is likely to continue on the street. 相似文献

This study examines the experiences of transgender college students in coping with stress in comparison to their cisgender peers. Undergraduate and graduate students from 73 colleges, totaling 26,292 participants, of which 47 identified as transgender completed an online survey. Transgender students reported greater exposure to trauma and higher rates of suicidal experiences, as well as different precipitants to reported stressful periods and sources of support than their cisgender peers. Implications for individual and group counseling as well as outreach and prevention to better support transgender students are explored. 相似文献

This paper describes a small‐scale study of what the authors describe as the ecosystemic approach to changing chronic problem behaviour. The study was undertaken with a group of twelve Leicestershire primary teachers. The technique is briefly described and then teachers' responses to it and its effectiveness are discussed. Four case study examples are presented and finally its potential is considered. Although in this case the work was undertaken with primary teachers, this is an approach which could also be useful at secondary level. 相似文献

The development of gratitude in youth has received increasing attention during the past several years, and gratitude‐based interventions have often been recommended for use in schools. Yet, the empirical status of the correlates of gratitude and the effects of gratitude‐based interventions on youths’ outcomes remains unclear. The present study addressed this ambiguity by systematically reviewing and meta‐analyzing original empirical journal articles investigating gratitude in youth through September 2014 (N = 20). Findings from the meta‐analysis of correlates indicate small‐to‐moderate convergent and discriminant evidence for gratitude as a subjective well‐being indicator in youth, yet other results indicate that gratitude measures have relatively poor test–retest reliability and/or predictive validity and that they have questionable concurrent validity with other gratitude measures. Moreover, findings from the meta‐analysis of intervention outcomes indicate that gratitude‐based interventions are, as a whole, generally ineffective and that much more intervention research is warranted. Implications of these findings for theory, future research, and the practice of school psychology are discussed. 相似文献

The geography of opportunity: spatial heterogeneity in founding rates and the performance of biotechnology firms 总被引:3,自引:0,他引:3
One of the most commonly observed features of the organization of markets is that similar business enterprises cluster in physical space. In this paper, we develop an explanation for firm co-location in high-technology industries that draws upon a relational account of new venture creation. We argue that industries cluster because entrepreneurs find it difficult to leverage the social ties necessary to mobilize essential resources when they reside far from those resources. Therefore, opportunities for high tech entrepreneurship mirror the distribution of critical resources. The same factors that enable high tech entrepreneurship, however, do not necessary promote firm performance. In the empirical analyses, we investigate the effects of geographic proximity to established biotechnology firms, sources of biotechnology expertise (highly-skilled labor), and venture capitalists on the location-specific founding rates and performance of biotechnology firms. The paper finds that the local conditions that promote new venture creation differ from those that maximize the performance of recently established companies. 相似文献

Abstract Nine males (age 24.7 ± 2.1 years, height 175.3 ± 5.5 cm, body mass 80.8 ± 7.2 kg, power clean 1-RM 97.1 ± 6.36 kg, squat 1-RM = 138.3 ± 20.9 kg) participated in this study. On day 1, the participants performed a one-repetition maximum (1-RM) in the power clean and the squat. On days 2, 3, and 4, participants performed the power clean, squat or jump squat. Loading for the power clean ranged from 30% to 90% of the participant's power clean 1-RM and loading for the squat and jump squat ranged from 0% to 90% of the participant's squat 1-RM, all at 10% increments. Peak force, velocity, and power were calculated for the bar, body, and system (bar + body) for all power clean, squat, and jump squat trials. Results indicate that peak power for the bar, body, and system is differentially affected by load and movement pattern. When using the power clean, squat or jump squat for training, the optimal load in each exercise may vary. Throwing athletes or weightlifters may be most concerned with bar power, but jumpers or sprinters may be more concerned with body or system power. Thus, the exercise type and load vary according to the desired stimulus. 相似文献

In the library literature, a great deal of interest in patron-driven collection development has recently been expressed, especially in those programs that link acquisitions with interlibrary loan. However, the implementation of such programs has been limited, at least in part because of concerns over the potential for wasteful spending. The authors will attempt to address this common concern by assessing whether monies spent via a patron-driven acquisitions program were more or less effective than monies spent via traditional modes of acquisition. 相似文献
