分配公平是一个历史范畴,是随着历史的发展而变化的。分配公平之所以成为现代社会不可或缺的制度性特质,一方面是为了维系人之为人的基本权利和尊严;另一方面是基于维系社会合作体系的需要。在现代社会里,实现分配公平不仅是必要的,也是可能的:人类财富的日益增多使分配公平的实现具有现实的可能性;现代制度文明也为分配公平的实现提供了制度保障。分配公平已经成为中国特色社会主义制度基本的价值理念和价值准则。  相似文献

The association between current level of suicidal ideation and physical activity was tested in a broad sample of veterans seeking care from the Veterans Health Administration. It was hypothesized that the two variables would be significantly inversely related. It was further hypothesized that the relationship would be mediated by depressive symptoms, disturbed sleep, and a measure of heart rate variability based on existing research regarding physical activity and sleep. Due to the first hypothesis not being supported, the second could not be tested. Post hoc correlation analyses did find associations between physical activity and depressive symptoms, in expected directions, and are discussed. Possible explanations for the negative findings along with recommendations for future research to continue exploring links between suicide risk and physical activity are presented. We conclude by suggesting that physical activity may have promise as a risk reduction intervention and that prospective data are more likely to yield significant results than the cross‐sectional methodology employed in the current study.  相似文献

Are Muslims the “new Jews” of Europe? The spectacle of Middle Eastern and African refugees shuttled by train from camp to squalid camp has understandably drawn parallels to the darkest pages in twentieth-century continental history. Such a historical comparison between Islamophobia and antisemitism, however, risks missing their ongoing interrelation. This article examines that interrelation, arguing that Islamophobia and antisemitism now most resemble each other as complementary mechanisms for diverting the anxieties bred by the global economic order. Antisemitism has long scapegoated the Jews for capitalism’s tendency to produce outsized winners. But there has been no comparably global shorthand for the anxiety prompted by capitalism’s losers—until now. Muslim refugees help give a name, Islam, to the masses seemingly encroaching from the margins of the world system. The result, I argue, is the hardening of Islamophobia and antisemitism into the inextricable poles of a reactionary worldview. Taking France as a case study, the article reads the burkini bans prompted by the July 2016 terror attack in Nice as an expression of middle-class fear about downward mobility. Targeted at both internal Muslim leisure and external Muslim encroachment, the bans evoke how European unease about globalization increasingly takes Islamophobic form. Such intolerance threatens not only to lodge Islamophobia at the heart of a reconstituted Europe but also to erode the vigilance against antisemitism once characteristic of the postwar European project.  相似文献

The experience of the most distressing patient suicide on Flemish psychiatrists is described. Of 584 psychiatrists, 107 filled a self‐report questionnaire. Ninety‐eight psychiatrists had been confronted with at least one patient suicide. Emotional suffering and impotence were the most common feelings reported. Changes in professional practice were described and included a more structured approach to the management of suicidal patients. Colleagues and contact with the patient's family were the most frequently used sources of help, whereas team case review and colleagues were rated as the most useful ones. Patient suicide leads to emotional suffering and has a considerable professional impact.  相似文献

This study employed latent growth curve analysis to evaluate the interactive effects of two specific facets of impulsivity (i.e., negative urgency [NU] and premeditation [PRE]) and negative emotions (NE) on the developmental trajectory of nonsuicidal self‐injury (NSSI) among 3,453 (57% females) Chinese community adolescents. Participants completed questionnaires assessing NSSI, NU, PRE, and NE (i.e., depression, anxiety, and stress) at three waves of time. The initial levels of NE and NU significantly predicted the initial level of NSSI. Changes in NE and NU significantly predicted change in NSSI. Moreover, the initial levels of NU and PRE significantly moderated the relationship between the initial levels of NE and NSSI, such that among individuals with higher NU or less PRE, the three NE were associated with a higher level of NSSI. Additionally, among individuals with a faster increase in NU, depression and anxiety were associated with a faster increase in NSSI. These findings suggest that adolescents with trait impulsivity, especially in the form of NU, are more vulnerable to the engagement in NSSI.  相似文献
