The study examines the association between ideological worldviews among youth and the sense of distress resulting from political events. It examines two hypotheses: the first is that events that contradict ideological worldviews are associated with greater distress levels and the second is that the higher the level of ideological commitment, the higher the distress level will be, regardless of the type of stressor. Therefore this study examines distress levels among right-wing adolescents exposed to two different political stressors: (a) Palestinian terror—which matches their right-wing ideology that regards the Palestinians as an enemy, and (b) the evacuation of settlements—which contradicts their right-wing ideology. As expected, higher distress levels were found during evacuation of settlements, compared to the response to Palestinian terror. It was also found that ideological commitment was positively associated with levels of distress with regard to both stressors. The study was supported by the R&D Center—Samaria & Jordan Rift and by the Adler Research Center, Tel Aviv University.  相似文献

Research indicates that posttraumatic stress symptoms (PTSS) induced by war trauma may be transmitted to veterans’ wives and offspring (secondary traumatic stress; STS). However, the interplay between family members’ characteristics has not been accounted for in such processes. Taking a family systems perspective, we examine the contributions of fathers’ PTSS, mothers’ STS, marital adjustment, and self‐disclosure of both parents to offspring's STS and test whether marital quality applies as a mechanism of parent–child transmission. Combat veterans and former prisoners of war (N = 123), their spouses, and adult offspring were investigated in a multiple‐step mediation analysis. The results highlight the mother's crucial role in trauma transmission and suggest that strengthening the marital relationship may buffer the transmission of fathers’ PTSS to offspring.  相似文献

Gertrude Stein was not only a fairly open lesbian but also Jewish, expatriate, and androgynous—all attributes that often retarded mass-market success. Why then was she so popular? The article offers original research highlighting how Stein was constructed as a kind of “opium queen” in the popular American press, and the ways that this decadent, bohemian celebrity persona allowed her to operate as “broadly queer” rather than “specifically gay” in the American cultural imaginary—a negotiation that accounts for the mass-market success rather than censure of The Autobiography of Alice B. Toklas despite the unparalleled visibility of its lesbian erotics.  相似文献

SUMMARY

This study explores the perspectives of service providers and youth advocates on bullying of lesbian, gay, bisexual and transgender (LGBT) youth and intersectionalities in LGBT peer victimization. In depth, semi-structured interviews were conducted with nine key informants (4 male, 4 female, 1 transgender male; 4 gay, 3 lesbian, 2 non-identified; 6 white, 1 South Asian, 2 Middle Eastern) recruited using purposive sampling from diverse education and social service settings. Narrative thematic analysis and a constant comparative method were used to identify themes. Five themes emerged from the data: (1) “transgressing gender norm boundaries”; (2) homophobic sexism vs. sexist homophobia; (3) “you choose sexuality or you choose race”; (4) newcomer youth and citizenship; and (5) “multiple wires together … create the cage.” Findings suggest the importance of an intersectional approach to conceptualizing and addressing LGBT bullying and to uncovering the differential experiences of bullying among LGBT youth. Bullying related to sexual orientation should not be assumed to be the only or primary form of violence shaping the lives of LGBT youth.  相似文献

The asymptotic null distribution of the locally best invariant (LBI) test criterion for testing the random effect in the one-way multivariable analysis of variance model is derived under normality and non-normality. The error of the approximation is characterized as O(1/n). The non-null asymptotic distribution is also discussed. In addition to providing a way of obtaining percentage points and p-values, the results of this paper are useful in assessing the robustness of the LBI criterion. Numerical results are presented to illustrate the accuracy of the approximation.  相似文献

We consider the linear feature selection problem of obtaining a nonzero 1 × n matrix B which minimizes the probability of misclassification based on the Bayes decision rule applied to the random variable Y = BX, where X is a random n-vector arising from one of m Gaussian populations with equal covariances and equal apriori probabilities. It is shown that the optimal B satisfies a fixed point equation B = F(B) which can be solved by successive substitution.  相似文献

A probabilistic risk assessment was conducted to evaluate the likelihood and ecological significance of potential toxic effects of diazinon in the Sacramento-San Joaquin system. Diazinon, an organophosphorus insecticide, is used in the Sacramento-San Joaquin River Basin as a dormant spray on almonds and other tree crops, as well as for other agricultural and urban applications. Diazinon and other pesticides have been detected in the Sacramento and San Joaquin Rivers and their tributaries. Diazinon exposure was characterized based on monitoring programs conducted in 1991-94. Diazinon effects were characterized using laboratory toxicity data for 63 species, supplemented by results from field mesocosm and microcosm studies. The assessment addressed the possibility that reductions in invertebrate populations could lead to impacts on species of fish that feed on those invertebrates. The risk assessment concluded that fish in these rivers are not at risk from the direct effects of diazinon in the water. Invertebrates are at greater risk, especially in agriculturally dominated streams and drainage channels during January and February. Cladocerans--including Daphnia magna and Ceriodaphnia dubia, two common bioassay species--are especially sensitive to diazinon and other organophosphates and are likely to be subject to acute toxic effects in some locations at some times. Any ecological damage that may occur, however, is brief and limited to cladocerans. None of the fish species of concern depend on cladocerans as critical components of their diet. Invertebrates that are not affected by observed concentrations of diazinon (copepods, mysids, amphipods, rotifers, and insects) are preferred foods for fish in the Sacramento-San Joaquin system.  相似文献
