Probability theory in fuzzy sample spaces   总被引:2,自引:0,他引:2  
This paper tries to develop a neat and comprehensive probability theory for sample spaces where the events are fuzzy subsets of The investigations are focussed on the discussion how to equip those sample spaces with suitable -algebras and metrics. In the end we can point out a unified concept of random elements in the sample spaces under consideration which is linked with compatible metrics to express random errors. The result is supported by presenting a strong law of large numbers, a central limit theorem and a Glivenko-Cantelli theorem for these kinds of random elements, formulated simultaneously w.r.t. the selected metrics. As a by-product the line of reasoning, which is followed within the paper, enables us to generalize as well as to bring together already known results and concepts from literature.Acknowledgement. The author would like to thank the participants of the 23rd Linz Seminar on Fuzzy Set Theory for the intensive discussion of the paper. Especially he is indebted to Professors Diamond and Höhle whose remarks have helped to get deeper insights into the subject. Additionally, the author is grateful to one anonymous referee for careful reading and valuable proposals which have led to an improvement of the first draft.This paper was presented at the 23rd Linz Seminar on Fuzzy Set Theory, Linz, Austria, February 5–9, 2002.  相似文献

Recent work on social status led to derivation of a new continuous distribution based on the exponential. The new variate, termed the ring(2)-exponential, in turn leads to derivation of two closely related new families of continuous distributions, the mirror-exponential and the ring-exponential. Both the standard exponential and the ring(2)-exponential are special cases of both the new families. In this paper, we first focus on the ring(2)-exponential, describing its derivation and examining its properties, and next introduce the two new families, describing their derivation and initiating exploration of their properties. The mirror-exponential arises naturally in the study of status; the ring-exponential arises from the mathematical structure of the ring(2)-exponential. Both have the potential for broad application in diverse contexts across science and engineering. Within sociobehavioral contexts, the new mirror-exponential may have application to the problem of approximating the form and inequality of the wage distribution.  相似文献

We investigated U.S. and Canadian reactions to workplace drug and alcohol testing programs. Canadian truck drivers (n = 183) deemed drug and alcohol testing policies less fair, and were less accepting of these policies, than their American counterparts (n = 153). We also compared the perspectives of recipients versus third-party observers with regard to their reactions to a drug testing program. Unlike the pattern observed among American observers, the responses by Canadian observers were highly similar to those of the recipients. Canadian observers were more inclined to file a formal protest regarding the implementation of a drug and alcohol testing program than were U.S. observers. The results also showed that procedural and interactional justice principles contributed to the program's fairness, acceptance, and lower levels of protest intentions in both Canada and the United States. We propose that scholars and practitioners can gain a better understanding of multinational reactions to drug and alcohol testing by considering not only cultural but also historical, social, political, and other environmental factors that can shape reactions to personnel practices.  相似文献

This study explored relationships between employee dissatisfaction with pay, perceptions of procedural justice, and organizational citizenship behavior. It was hypothesized that pay inequity would be negatively related to citizenship, while favorable perceptions of procedural and interpersonal justice would be positively related. Results provided strong support for the hypotheses only with regard to a dimension of citizenship labeled “compliance.” Implications for employee behavior in the workplace and the expression of grievances are discussed; future research directions are also offered.  相似文献

我国城市化危及土地资源持续利用的立法原因探析   总被引:1,自引:0,他引:1  
桑东莉 《城市问题》2003,(3):61-64,36
随着我国城市化进程的不断加快 ,土地资源供给的有限性与人们对土地资源需求的无限性之间的矛盾日益突显。而在此背景下重新修订公布的《土地管理法》在涉及建设用地需求的无限扩展与农业用地数量的持续下降这两个突出问题上 ,并没有明确政府的职能定位 ,也反映出了相关制度的模糊性。本文就此进行了探讨。  相似文献

基于调节焦点理论和公平启发理论,运用结构方程模型考量差异化人才管理对员工创新绩效的影响机制。结果显示:促进定向工作重塑在差异化人才管理与员工创新绩效之间起正向中介作用,防御定向工作重塑在二者间起负向中介作用;组织公平感正向调节差异化人才管理与促进定向工作重塑之间的关系,负向调节差异化人才管理与防御定向工作重塑之间的关系;组织公平感增强促进定向工作重塑的正向中介作用,削弱防御定向工作重塑的负向中介作用。  相似文献

依据2017年中国综合社会调查数据,运用有序概率模型,考量住房差异对居民社会公平感的影响及作用机理。结果显示:较少住房面积和无住房产权负向影响居民社会公平感;较多住房面积和拥有住房产权正向影响居民社会公平感;一套住房产权比多套住房产权更能促进居民社会公平感的提升。社会阶层认同和社会阶层预期在较少住房面积和无住房产权群体中表现出正向调节作用;在较多住房面积和拥有住房产权群体中表现出中介作用。住房差异在社会阶层上向流动时正向影响居民社会公平感。鉴于此,应保障住房权利,强化社会阶层预期,提高居民社会公平感。  相似文献
