AbstractThis paper develops almost sure convergence for sums of negatively superadditive dependent random vectors in Hilbert spaces, we obtain Chung type SLLN and the Jaite type SLLN for sequences of negatively superadditive dependent random vectors in Hilbert spaces. Rate of convergence is studied through considering almost sure convergence to 0 of tail series. As an application, the almost sure convergence of degenerate von Mises-statistics is investigated. 相似文献

Those involved in sustainability debates on developmental pathways concur in the synergistic potential of integrating traditional ecological knowledge (TEK) and Western scientific approaches. Transhumant pastoralism is a livelihood strategy adapted to spatiotemporal environmental variability in many mountainous and arid regions worldwide. This form of livelihood is based on a mobile logic that is increasingly threatened by novel lifestyles promoted from a Western mind-set and by climate change. The aim of this article is to identify and characterize the different perspectives of environmental and social issues in a pastoral region and their association with labor collaboration among extension agents, framed in an institutional action. We tackled the inquiry about viewpoints with Q methodology and related it to regional problems, alternative solutions, and future development pathways for transhumant pastoralism and landscape management in northwest Patagonia. We identified six perspectives and characterized them with their topological position in the social network. Mediating positions registered the highest network centrality of labor collaborations among agents, whereas more dominant perspectives emphasizing TEK or scientific knowledge registered intermediate centrality. There was consensus on the need for sustainable developmental options, but the emphasis on combining knowledge still needs convergent solutions. 相似文献

This article illustrates some of the ways in which the notion of (paid) work is actively being gendered, and how these gendering processes take place not only through organizational practices but also in discourses that circulate outside an organization in the private domain. Drawing on 15 in‐depth interviews with women who opted out of their own professional career in order to accompany their husbands on their overseas work assignment to Hong Kong, we demonstrate some of the benefits of using a discourse analytical approach to capturing and identifying the processes through which these women actively (although not necessarily consciously) gender the notion of work, thereby reinforcing the gender order and its male bias. We argue that identifying and making visible these gendered and gendering practices is an important component of, and a potential trigger for, change both in organizations as well as private contexts. 相似文献

爱国主义歌曲作为对祖国抒发赞颂之情的歌曲,是“光荣颂”“欢乐颂”“祝福颂”的有机统一,是培育和践行社会主义核心价值观的重要载体。从精神价值而言,爱国主义歌曲具有社会公共性、历史恒久性、无比崇高性。高校开展咏唱爱国主义歌曲活动,能增进学生对祖国的自豪之情,提升其民族自信,激发其报国之志。高校开展咏唱爱国主义歌曲活动,即要精选优异的爱国主义歌曲音乐本体,又要注重发挥高校教师的带头作用,还要加强学校各级组织机构和辅导员队伍的引领作用。高校党政领导对这类歌咏活动要进一步提高认识站位、增强重视程度、加强条件支持。 相似文献

How do changes in employment uncertainty matter for fertility? Empirical studies on the impact of employment uncertainty on reproductive decision-making offer a variety of conclusions, ranging from gender and socio-economic differences in the effect of employment uncertainty on fertility intentions and behaviour, to the effect of employment on changes in fertility intentions. This article analyses the association between a change in subjective employment uncertainty and fertility intentions and behaviour by distinguishing male and female partners’ employment uncertainty, and examines the variation in these associations by education. Using a sample of men and women living in a couple from the Swiss Household Panel (SHP 2002–2011), we examine through multinomial analysis how changes in employment uncertainty and selected socio-demographic factors are related to individual childbearing decisions. Our results show strong gendered effects of changes in employment uncertainty on the revision of reproductive decisions among the highly educated population. 相似文献

Abstract As a member of the Cairns Group, New Zealand is an excellent case for investigation of the impacts of market-based restructuring and the emergence of new mechanisms for regulation. The paper examines how agriculture in New Zealand has been impacted by economic reforms that have fundamentally changed the nature and interrelations of regulatory arrangements and economic processes. The paper sketches the origins of New Zealand's agricultural crisis and the main features of the reforms, outlines developments in several global commodity chains (meat, dairy, apples) that since the mid 1980s have shaped regulatory and governance adjustments, and explores dimensions of a reimaging of agriculture in new conditions. The paper concludes that agri-food restructuring in New Zealand is implicated in the wider integrative project of globalization. Agriculture's reconstruction reopens the scope and terms under which New Zealand labor and households might be able to participate in the agri-food sector. 相似文献

和平崛起的中国面临从不平等的国际社会成员变成平等的成员,从国际体系的抗争者变成受益者,从国际舞台的边缘走向中心,国际关系的重心由大西洋转向太平洋等国际环境等基本特征,应作出适当的外交战略选择。把握方向,坚持"韬光养晦";承担责任,善于"有所作为";求同存异,阐述和谐主张;擅用传播,塑造良好形象等应是当前中国外交战略中应有的内容。 相似文献

在用方差控制投资组合风险的同时,由于方差的对称性导致投资组合的收益也受到限制. 相比之下,下偏距 (lower partial moment: LPM) 由于具有只控制风险,而不限制收益的特点,在近年来倍受关注. 但在非正态假设下,LPM 无法获得良好的解析性质. 在对资产收益分布未知的假设下,通过使用最坏情形下的LPM来度量投资组合的损失,提出了具有多元权值约束的鲁棒积极投资组合问题,并获得了具有m( m=0,1,2) -阶 LPM 约束的鲁棒积极投资组合问题的解析解. 通过分析解的性质和比较问题的有效前沿,得到了许多有趣的和新颖的结果. 数值结果比较表明,鲁棒LPM模型比经典的均值-方差模型具有许多更好的性能. 相似文献
