纳什均衡理论由于具有十分强的解决问题的能力,不仅成了现代理论经济学分析方法的基础,而且还对自然科学、社会科学的许多领域产生了影响.但纳什均衡理论不是完美无缺的,"象棋博弈"、"性别博弈"、"蜈蚣博弈"都对纳什均衡的有效性提出了质疑.这就要求纳什均衡理论有新的发展,这种发展既包括超越非合作博弈与合作博弈的传统分类,也包括对纳什均衡理论逻辑起点--经济人的超越和扬弃. 相似文献

政策范式是决策主体的政策思维与政策风格的反映,是近年来公共政策研究中兴起的重要分析方法。以政策文本分析方法为基础,围绕政策问题、政策价值取向、政策工具与政策话语四个方面,对改革开放以来我国农民市民化政策范式变迁进行研究,发现农民市民化政策不仅在话语措辞层面发生了深刻变化,而且在政策问题认定、政策目标定位、政策工具选择层面也经历了渐进的变迁过程。总体而言,农民市民化政策范式渐趋包容性、公平性与人本性,不断彰显农民与市民共生进化的理念将成为市民化政策的重要特点与发展主流。 相似文献

Studying the right tail of a distribution, one can classify the distributions into three classes based on the extreme value index γ. The class γ>0 corresponds to Pareto-type or heavy tailed distributions, while γ<0 indicates that the underlying distribution has a finite endpoint. The Weibull-type distributions form an important subgroup within the Gumbel class with γ=0. The tail behaviour can then be specified using the Weibull tail index. Classical estimators of this index show severe bias. In this paper we present a new estimation approach based on the mean excess function, which exhibits improved bias and mean squared error. The asserted properties are supported by simulation experiments and asymptotic results. Illustrations with real life data sets are provided. 相似文献

Eefje De Kroon 《Journal of Muslim Minority Affairs》2016,36(2):153-183
This article examines the extent to which Islamic law is accommodated in the Netherlands, by analysing legislation, case law, and the political discourse in the field of Islamic divorce, and focuses on the tension and proposed balance between gender equality and freedom of religion. It finds that, as the priority lies with protecting Muslim women’s rights, Muslim law in the Netherlands remains in the unofficial sphere, potentially alienating Muslim communities. This article explores whether and how Dutch law could continue to ensure respect for gender equality while working towards greater respect for a minority group’s cultural and religious freedom. Two options are presented in this regard: more responsibilities for Civil and Criminal courts, or the establishment of Sharia Councils. Lessons are drawn from the United Kingdom’s experiences. 相似文献

The present research examined whether the emotions of others (i.e., disappointment versus happiness with respect to a received outcome) influence own self-esteem when being overpaid. Results from two experiments demonstrated that participants reported higher performance self-esteem when the other expressed happiness rather than disappointment. This effect was only found in the condition where one was overpaid relative to the condition where one did not yet know one’s own outcome. In the second experimental study we further found that this interaction between the emotion of the other and the distribution situation only emerged among participants low (relative to high) in personal need for structure. Implications with respect to the relationship between overpayment and self-esteem and the interpersonal effects of emotions in this process are discussed. 相似文献

This study translated and validated the Substance Use Risk Profile Scale (SURPS) among 13 to 18 year old Sri Lankan adolescents attending school. A standard systematic translation procedure was followed to translate the original SURPS into Sinhala language. A Delphi process was conducted to determine judgmental validity of Sinhala SURPS. Confirmatory factor analysis was performed to test the translated version against the original theoretical model of the SURPS. Test-retest and internal consistency were used to ensure reliability. A few terms in one of the items posed some difficulty in translating into Sinhala. Adequate judgmental validity was determined except for one item, which was modified to suit the Sri Lankan setting. The four subscales introversion/ hopelessness, impulsivity, sensation seeking and anxiety sensitivity showed satisfactory test-retest reliability estimates of .74, .68, .76, and .88, respectively. The Sinhala SURPS is applicable in Sri Lankan context. Several implications based on the results are discussed. 相似文献

以南京市青奥轴线地下交通工程主隧道基坑非对称开挖水平位移监测数据为依据,对水平位移监测值与ABAQUS数值模拟值进行对比分析。得出结论:墙体水平位移首先是悬臂开挖的墙顶向外发生三角形分布的位移,然后随着支撑的架设,墙体发生转动,数值模拟值与实际监测值基本符合;在开挖面附近的土压力,随着墙体高度的增加而增大;在支撑以上部分,模拟值要小于计算值,而在开挖面以下部分,则模拟值大于计算值;随着悬臂段开挖深度的增加,悬臂段最大土压力值也在逐渐增加,墙底土压力值在逐渐减小。 相似文献

Networks for Welfare Provision: Getting a Grip on Processes of Social Exclusion by Evaluating Network Effectiveness 下载免费PDF全文
It has been repeatedly stated that the topic of network effectiveness has often been neglected. This has led to a situation of ‘network euphoria’ amongst practitioners and policymakers with regard to the creation of networks as a means to (re‐)organize welfare provision. Starting from a case study of networks for welfare provision in two Belgian cities, this article focuses on the effectiveness of service delivering networks at the client level, which is understood as the contribution of the network in improving the conditions of life of those being served or targeted by the network. Therefore, we focused on the collective efforts via these networks (e.g. by creating a night shelter or by conducting case consultations) to look after a population of homeless people who face multiple problems and are not able yet to benefit from welfare provision. Our findings revealed that these networks were able to realize a ‘collaborative advantage’ by filling in service gaps and by overcoming fragmentation of care. Nevertheless, these networks equally maintained criteria that restricted the accessibility or usefulness of welfare services provided to homeless people. In the concluding section, we highlight some of the factors that could help us to explain our findings and highlight the tension between the effectiveness of networks at the client level and the effectiveness at the organizational level. 相似文献

We propose a measure for interaction for factorial designs that is formulated in terms of a probability similar to the effect size of the Mann–Whitney test. It is shown how asymptotic confidence intervals can be obtained for the effect size and how a statistical test can be constructed. We further show how the test is related to the test proposed by Bhapkar and Gore [Sankhya A, 36:261–272 (1974)]. The results of a simulation study indicate that the test has good power properties and illustrate when the asymptotic approximations are adequate. The effect size is demonstrated on an example dataset. 相似文献
