Community violence is increasingly recognized as a risk factor for serious psychological problems with children particularly vulnerable to its effects. This article summarizes the existing knowledge on the effects of chronic exposure to community violence, highlights essential issues in assessing children for both exposure and resulting trauma from community violence, and provides treatment guidelines for those affected children. 相似文献

This paper sets out to explore factors that may be associated with food hardship among young people who reside in public housing (N?=?124). The study is guided by Family Stress Theory and uses data from a cross-sectional study of African–American adolescents living in a public housing neighborhood located in West Baltimore. Results suggest that food security (defined as availability, accessibility, and adequacy) was negatively related to mother’s incarceration, large households, household experiencing material hardships, and interpersonal conflict as well as violence. It was also linked to community disorganization. Program and policy implications are suggested. 相似文献

Literature shows that youth who identify as lesbian, gay, bisexual, transgender, or queer (LGBTQ) experience high rates of victimization across various contexts, though there is little research specific to partner violence victimization. Given the deleterious effects of partner violence seen in both youth generally and LGBTQ adults, it is imperative to investigate partner violence among LGBTQ youth. The authors investigated the prevalence of partner violence among a community sample of LGBTQ youth (N = 140) and examined potential correlates of said violence. Approximately half of the participants had ever experienced some form of partner violence. Rates of ever experiencing partner violence were approximately 2.5 times higher for youth who had binge drank in the past month or ever experienced familial abuse and nearly three times higher for youth who had experienced an episode of homelessness in the past year. Implications for professionals who serve LGBTQ youth are discussed. 相似文献

This article extends the work by Holly and Gardiol (2000) (A score test for individual heteroscedasticity in a one-way error component model. In: Krishnakumar, J., Ronchetti, E., Eds. Panel Data Econometrics: Future Directions. Elsevier, North-Holland, Amsterdam, pp. 199–211, Ch. 10) to the two-way error components model. It deals exclusively with a joint heteroscedasticity test by first deriving Rao's efficient score statistics. Then, based on appropriate set of assumptions, we deduce the asymptotic distribution of the score under contiguous alternatives. Finally, we provide the expression for the score test statistic in the presence of heteroscedasticity and discuss its asymptotic local power. 相似文献

This article establishes the foundation for research on collective intuition through a study of decision making and organizational learning processes in police senior management teams. We conceptualize collective intuition as independently formed judgement based on domain‐specific knowledge, experience and cognitive ability, shared and interpreted collectively. We contribute to intuition research, which has tended to focus its attention at the individual level, by studying intuition collectively in team settings. From a dual‐process perspective, we investigate how expert intuition and deliberation affect decision making and learning at various levels of the organization. Furthermore, we contribute to organizational learning research by offering an empirically derived elaboration of the foundational 4I framework, identifying additional ‘feed‐forward’ and ‘feedback’ loop processes, and thereby providing a more complete account of this organizational learning model. Bridging a variety of relevant but previously unconnected literatures via our focal concept of collective intuition, our research provides a foundation for future studies of this vitally important but under‐researched organizational phenomenon. We offer theoretical and practical implications whereby expert intuitions can be developed and leveraged collectively as valuable sources of organizational knowledge and learning, and contribute to improved decision making in organizations. 相似文献

In this paper, we extended a parallel system survival model based on the bivariate exponential to incorporate a time varying covariate. We calculated the bias, standard error and rmse of the parameter estimates of this model at different censoring levels using simulated data. We then compared the difference in the total error when a fixed covariate model was used instead of the true time varying covariate model. Following that, we studied three methods of constructing confidence intervals for such models and conclusions were drawn based on the results of the coverage probability study. Finally, the results obtained by fitting the diabetic retinopathy study data to the model were analysed. 相似文献

AbstractObjectives: Lesbian, gay, bisexual, and queer/questioning (LGBQ), and transgender/nonbinary (trans/NB) youth experience health disparities. Much research combines gender identity with sexual orientation or siloes them, ignoring intersections. Methods: Logistic regressions with representative data from 2015 Healthy Kids Colorado Survey (n?=?15,970) explores sexual risk. Results: Findings indicate LGBQ and trans/NB youth have differential levels of sexual risk (drugs during sexual interactions, not using condoms) compared to cisgender heterosexual peers. Other identities, mental health, and bullying are also related. Conclusions: There is a need for culturally responsive bullying prevention, mental health support, education, and sexual health services for marginalized populations. 相似文献

Guided by Bowen theory, we investigated the relationships between parent–child triangulation, parental differential treatment (PDT), sibling warmth, and individual depressive symptoms in a sample of 77 sibling dyads, aged 18–25 years, recruited through undergraduate classes at a U.S. public University. Results of the actor–partner interdependence models suggested that being triangulated into parental conflict was positively related to both siblings’ perception of PDT; however, as one sibling felt triangulated, the other perceived reduced levels of PDT. For both siblings, the perception of higher levels of PDT was related to decreased sibling warmth and higher sibling warmth was associated with fewer depressive symptoms. The implications of these findings for research and the treatment of depression in the college‐aged population are discussed. 相似文献
