What does ethnicity (or race) have to do with the struggle over land in post-1967 Israeli occupied territories? On the Israeli scene, post-1967 settlers tend to be depicted as religiously motivated Jews of Ashkenazi descent and often Anglophone origin, while Jews from the Middle East and North Africa (Mizrahim) tend to be associated with development towns and other locations known for high unemployment and generally depressed socio-economic situations. Prior to the Israeli disengagement of 2005 there was a great deal of public attention focused on the controversy surrounding settlement in the occupied territories. The conflict often appeared in stark oppositions of ‘left-wing secular liberals’ against ‘right-wing religious radicals.’ The most outspoken messianic settlers and those often depicted in mainstream media tended to be of Ashkenazi origin, a representation that denies the presence of Jews of Middle Eastern and North African descent (Mizrahim) in the settlements then slated for evacuation. This article raises a set of questions about the hegemonic representation of the Israeli socio-political-religious scene regarding the relative absence of representations of Mizrahi Jews who lived in the settlements of Gush Katif in the Gaza Strip. It asks both what this representation accomplishes and what is at stake in recognizing the Mizrahi presence as settlers in post-1967 occupied territories. 相似文献

In 2005 the Texas 79th legislature passed Senate Bill 6, which included mandates to address disproportionality. This article will describe how the Texas Department of Family Protective Services in collaboration with Casey Family Programs' Texas State Strategy systems improvement initiative is addressing disproportionality statewide through promising practices and innovations in undoing racism trainings, values-based leadership development, and community engagement strategies. 相似文献

A longitudinal report of 156 gay, lesbian, and bisexual youths examined changes in sexual identity over time. Fifty-seven percent of the youths remained consistently self-identified as gay/lesbian, 18% transited from bisexual to gay/lesbian, and 15% consistently identified as bisexual over time. Although youths who consistently identified as gay/lesbian did not differ from other youths on time since experiencing sexual developmental milestones, they reported current sexual orientation and sexual behaviors that were more same-sex centered and they scored higher on aspects of the identity integration process (e.g., more certain, comfortable, and accepting of their same-sex sexuality, more involved in gay-related social activities, more possessing of positive attitudes toward homosexuality, and more comfortable with others knowing about their sexuality) than youths who transited to a gay/lesbian identity and youths who consistently identified as bisexual. Contrary to the hypothesis that females are more sexually fluid than males, female youths were less likely to change identities than male youths. The finding that youths who transited to a gay/lesbian identity differed from consistently gay/lesbian youths suggests that identity integration continues after the adoption of a gay/lesbian sexual identity. 相似文献

A graph \(G\) has an efficient dominating set \(D \subseteq V(G)\) if \(D\) dominates every vertex exactly once. In this paper we introduce the study of the family \({S_k}\) of graphs for which every \(G-S\) is efficiently dominatable for \(0 \le |S|\le k\). Assuming that \(G\) is efficiently dominatable, the efficiency index is the largest value k for which \(G\) is in \(S_k\). A graph \(G\) will be called super-efficient if every induced subgraph is efficiently dominatable. We give some characterizations for trees, grids, cylinders and torii to be super-efficient. 相似文献

The current study examines the associations between employment status and mental health and the mediating role of material hardship among low-income households in South Korea. This study uses regression models with a rich set of control variables and lagged dependent variable models with a nationally representative sample of 1113 low-income working-age household heads from the Korean Welfare Panel Study (KOWEPS). We find that the nonstandard employment and unemployment statuses are associated with a higher level of depression and a lower level of self-esteem, when compared to a standard employment status. These negative associations are partially mediated by an increased material hardship risk. Policy implications to improve employment conditions and mitigate material hardship are discussed. 相似文献

The U.S. Environmental Protection Agency's (EPA) Integrated Risk Information System (IRIS) database, the authoritative source of U.S. risk assessment toxicity factors, currently lacks an oral reference dose (RfD) for copper. In the absence of such a value, various health-based reference values for copper are available for use in risk assessment. We summarize the scientific bases and differences in assumptions among key reference values for ingested copper to guide selection of appropriate values for risk assessment. A comprehensive review of the scientific literature best supports the oral RfD of 0.04 mg/kg body weight/day derived by EPA from their Drinking Water Action Level. This value is based on acute gastrointestinal effects but is further supported by broader analysis of copper deficiency and toxicity. 相似文献

Research on learning effects in mathematical programming models for optimum resource allocation has called attention to the difficulty in solving such models in their original nonlinear form. In this paper, systematically varying sizes of linear segments are designed to approximate productivity changes along the learning curve, and a single separable linear programming model is developed. With production complementarity and learning transmission between products, a more realistic resource allocation and production scheduling problem emerges. Two cases of learning transmissions are considered, and the model design process, which defines a decision problem that can be solved by a simplex algorithm, is demonstrated. 相似文献
