We give sufficient conditions for the asymptotic normality of linear combinations of order statistics ( \(L\) -statistics) in the case of simple random samples without replacement. In the first case, restrictions are imposed on the weights of \(L\) -statistics. The second case is on trimmed means, where we introduce a new finite population smoothness condition. 相似文献

Divorce is a stressful life transition and does not have a single cause. This article presents the results of qualitative research on the causes for separation as perceived by women in Slovenia. Ten interviews were carried out with women divorced for less than 10 years and between 29 and 57 years old. The women created their own meanings of the reasons for divorce, all of which corresponded with other studies. The findings confirm the complex factors that contribute to the disintegration of marriage and that existed prior to the divorce. The research results present a vantage point for developing preventive activities that foster improved quality of interpersonal relationships in Slovenia. 相似文献

This article describes the harassment patterns and the risk profile in trans people living in Spain. A sample of 212 trans persons, aged 10–62, participated in this cross-sectional study. Results showed a high percentage of harassment (59.9%) and frequency of daily harassment (12.6%), especially verbal attacks (59%) that occurred in public spaces (49.1%) and within educational contexts (46.2%). Harassment is more prevalent in trans women than men. Those who disclose their gender identities at a younger age experience higher percentages and frequency of harassment than those who disclose at an older age. They also suffer more harassment of different types. The risk profile of harassment indicates that older trans women are more likely to suffer harassment than younger ones, and the risk decreases each year they delay their gender identity disclosure. The elimination of transphobic attitudes and the promotion of gender justice should be priority strategies in Spain. 相似文献

We construct Edgeworth and empirical Edgeworth approximations to distribution functions of finite population L-statistics and compare their accuracy with that of the normal approximation and the bootstrap approximation in a simulation study. 相似文献

This study aims to resolve the contradictory previous research findings on the relationship between individualism–collectivism and innovation. We draw on innovation theory and relate to the difference between non-technological (management) and technological innovation types as well as to the distinction between exploration and exploitation (invention and commercialization of technological innovations). Using Community Innovation Survey (CIS) 2006 micro data for innovation at the organizational level in 13 countries – along with Hofstede, 1980, Hofstede, 2001, GLOBE (2005), and Schwartz (2006) scores for individualism–collectivism – we apply Hierarchical Linear Modeling (HLM). The results indicate that individualism is positively related to the invention phase, whereas collectivism is beneficial for the commercialization of innovative ideas. Furthermore, in collectivistic cultures, management innovation plays a more important stimulating role in enhancing technological innovation than it does in individualistic ones. This provides the managers with an idea of when innovation processes in their companies would be more favorable versus detrimental. 相似文献

The global garment industry is currently being reshaped in dramatic ways through processes of trade liberalization, delocalization and interfirm and interregional competition. There has been much speculation about the increasing importance of factor (especially labour) costs in fuelling further rounds of de‐localization of garment production towards low‐cost production locations, such as China and India. However, the extent to which these processes mean the end to garment production in higher factor‐cost locations, including those neighbouring the major clothing markets of the USA and the EU, is open to question. In this article we interrogate the interregional shifts in garment sourcing taking place in Europe and its surrounding regions. While factor costs (including labour) are important determinants of the geography of sourcing, a range of other costs (logistical and policy costs) are important in structuring the geographies of global and regional production. Firms in the Slovak Republic are responding to increasing competitive pressures and we assess how trans‐border sourcing, subcontracting and FDI are being integrated into strategies to sustain European production networks. We highlight the emergence of cross‐border production relocation to Ukraine as one specific strategy. We examine the product specificity of these changes and the ways in which they are embedded within already existing production networks, forms of cross‐border contracting and central European trade regimes. In other words, we explore some of the forces that shape the somewhat tentative continuation of garment production for export to EU markets in central Europe despite the ‘spectre of China’. 相似文献

Although urbanization is generally considered a major threat to local and global biodiversity, some recent studies have shown that urban environments provide suitable habitat for some wildlife species, including carnivores, yet little is known about the factors that determinate their occurrence and habitat preferences. The main aim of this study was to examine the relative importance of habitat characteristics in relation to carnivore occurrence along an urban–rural gradient in the Central Europe. Carnivore occurrence was monitored using scent stations (summer period) and snow tracking (winter period) in the regional city which was divided into the network of 154 quadrates (25 ha/quadrate) for the purposes of this study. From a total of six recorded native carnivore species, the stone marten Martes foina and the least weasel Mustela nivalis were the most dominant and widespread species in both study periods. PCA analysis revealed the existence of two informative axes corresponding to (A) urban vs. non-urban habitat and (B) residential vs. industrial areas. Surprisingly, the only species exhibiting marked habitat selectivity and avoidance of highly urbanized areas was the red fox (i.e. negative correlation with the first PCA axis). The stone marten tends to avoid industrial areas and prefers residential areas; however its presence/absence was not associated with the first PCA axis. On the other hand, the ermine stoat and the least weasel were relatively unselective according to our results. In conclusion, our results demonstrate high adaptability of various species of carnivore mesopredators to urban environment; however their response to the level of urbanization and habitat characteristics exhibits interspecific variation. 相似文献
