伊朗是阿富汗的西邻,在阿富汗有着重要影响力,尤其是在语言、宗教和文化等方面。从美国发动打击阿富汗“塔利班”政权的战争后至今,伊朗在阿富汗政治和经济重建、民族和解、打击毒品走私等方面都发挥着重要作用。伊朗反对美军在阿富汗长期存在。2014年后,国际安全援助部队将大部分撤出阿富汗。伊朗会继续推动阿富汗政治、社会稳定,防止“塔利班”东山再起,参与阿富汗经济重建,但其政策也会根据地区和国际形势变化进行调整。  相似文献

Based on a sample of British dual earner families with young children drawn from the National Diet and Nutrition Survey, the paper examines their food practices, in particular the conditions under which families are able to eat together or not during the working week. The concept of synchronicity is drawn upon to shed light on whether meals and meal times are coordinated in family life and the facilitators and constraints upon coordination. The paper suggests that whether families eat together is not only influenced by parents' work time schedules but also children's timetables relating to their age and bodily tempos, their childcare regimes, their extra-curricular activities and the problem of coordinating different food preferences and tastes.  相似文献

Using data from Finland, this paper contributes to a small but growing body of research regarding adult children's education, occupation, and income and their parents' mortality at ages 50+ in 1970–2007. Higher levels of children's education are associated with 30–36 per cent lower parental mortality at ages 50–75, controlling for parents' education, occupation, and income. This association is fully mediated by children's occupation and income, except for cancer mortality. Having at least one child educated in healthcare is associated with 11–16 per cent lower all-cause mortality at ages 50–75, an association that is largely driven by mortality from cardiovascular diseases. Children's higher white-collar occupation and higher income is associated with 39–46 per cent lower mortality in the fully adjusted models. At ages 75+, these associations are much smaller overall and children's schooling remains more strongly associated with mortality than children's occupation or income.  相似文献

The history of the Ukrainian Hetmanate has been studied from the perspective of war, political struggle, and diplomacy. This article studies various aspects of women’s lives in Cossack society: their legal status, economic rights, role in society, relations with husbands and sons, the tradition of women’s presence at formal receptions, and their interference in political life. It is also about “women in politics,” “witches,” sex and premarital relations, kidnappings, and love affairs. The general argument is that the position of Ukrainian women was closer to that of women in Catholic Poland than in Muscovy.  相似文献

This study provides an historical overview of the IDF Spokesperson’s Unit (ISU) from the early years of the State of Israel until 2009. Analyzing five periods during which the ISU played a key role in Israel's public diplomacy, this research sheds light on the challenges the ISU faced in different periods and circumstances and examines how the ISU tried to modify its methods and actions in response to geopolitical changes and media development, albeit not always successfully. The study suggests better understanding the adaptation process by applying a three-layer framework for analysis: the tactical layer, the strategic layer and the perceptional layer. The findings of this work demonstrate that in adapting to new circumstances, the ISU focused mainly on the tactical response level, with the result that it did not undertake any review or debate over the need for deeper perceptional changes in ISU policies.  相似文献

Low‐ and middle‐income countries (LMIC) are faced with disproportionately high levels of unmet child mental health needs. This study explored through interviews the perspectives of 17 inter‐agency service stakeholders from Brazil, Indonesia, Kenya, Pakistan, Rwanda and Turkey on existing supports and challenges. Four themes emerged on the holistic nature of children's mental health needs linked with disadvantage; limited resources and skilled workforce; stigma; and strategies for future implementation, including awareness, parental engagement, skills‐based programmes and cultural adaptation. Stakeholder input is essential in conceptualising, developing and evaluating culturally appropriate interventions for vulnerable children in LMIC.  相似文献

Since the early 1990s, there has been investment in women's entrepreneurship policy (WEP) in Sweden, which continued until 2015. During the same period, Sweden assumed neoliberal policies that profoundly changed the position of women within the world of work and business. The goals for WEP changed as a result, from entrepreneurship as a way to create a more equal society, to the goal of unleashing women's entrepreneurial potential so they can contribute to economic growth. To better understand this shift we approach WEP as a neoliberal governmentality which offers women ‘entrepreneurial’ or ‘postfeminist’ subject positions. The analysis is inspired by political theorist Nancy Fraser who theorized the change as the displacement of socioeconomic redistribution in favour of cultural recognition, or identity politics. We use Fraser's concepts in a discourse analysis of Swedish WEP over two decades, identifying two distinct discourses and three discursive displacements. Whilst WEP initially gave precedence to a radical feminist discourse that called for women's collective action, this was replaced by a postfeminist neoliberal discourse that encouraged individual women to assume an entrepreneurial persona, start their own business, compete in the marketplace and contribute to economic growth. The result was the continued subordination of women business owners, but it also obscured or rendered structural problems/solutions, and collective feminist action, irrelevant.  相似文献

This paper considers estimation and prediction in the Aalen additive hazards model in the case where the covariate vector is high-dimensional such as gene expression measurements. Some form of dimension reduction of the covariate space is needed to obtain useful statistical analyses. We study the partial least squares regression method. It turns out that it is naturally adapted to this setting via the so-called Krylov sequence. The resulting PLS estimator is shown to be consistent provided that the number of terms included is taken to be equal to the number of relevant components in the regression model. A standard PLS algorithm can also be constructed, but it turns out that the resulting predictor can only be related to the original covariates via time-dependent coefficients. The methods are applied to a breast cancer data set with gene expression recordings and to the well known primary biliary cirrhosis clinical data.  相似文献

新时期网络参政对中国民主政治发展促进作用将更加明显,是有中国特色民主政治发展的重要内容之一。网络参政的作用已经引起了党和国家领导人的重视,地方党和政府的负责人也逐渐注意到网络参政的实际意义,其作用主要体现在:促进参与式民主的发展;促进传统集权等级制权力结构的转换;促进社会平等;促进政治、政府公开的发展;促进选民与人大代表的沟通;促进公民政治社会化的加强。网络参政还是把双刃剑,应该加强规范和管理。  相似文献
