欧盟对失业采取的预防和激励政策分析

对失业人员采取预防和激励政策是欧盟共同就业策略的核心内容,1998年以来,欧盟成员国在实施积极的劳动力政策和改革预防与激励政策方面有很大的进展,特别是在加强公共就业部门的现代化改革方面成绩显著。这一策略的实施给各成员国在不同程度上带来了积极的影响。     

基于时间属性的电子邮件真实性鉴定研究

社会的发展和技术的进步使得电子邮件被用作证据采纳运用成为可能,但这种可能首要解决的问题是电子邮件的真实性鉴定。现有电子邮件真实性鉴定方法均有不足之处,而把电子邮件的时间属性作为切入点来分析和判断电子邮件真实性的鉴定方法原理易懂,操作简便,容易实现电子邮件真实性鉴定目的。基于时间属性的电子邮件真实性鉴定方法包括时间信息的解析和时间属性逻辑关系的判断。如果判断解析的时间出现逻辑关系矛盾,则可以认定电子邮件遭到篡改,不满足作为证据的真实性条件。     

村支书和村委会主任:村民自治背景下的权力博弈

作为传统的一把手,村支书一直执掌村中决策和管理大权。然而随着村民自治在农村的强力推进,村委会的影响力也在不断提升,村民直选的村主任作为村庄的法定代表,要扮演“当家人”的角色,不可避免地面临着与传统村庄权威村支书的权力再分配问题,即政务村务治理权的力量博弈。实际上,村党支部和村委会关系的协调与否,不仅同各自的权力来源和村支书与村委会主任的个人影响力有直接关系,而且同现实状况关系密切,博弈结果因而呈现多样化。     

Which Scoring Rule Maximizes Condorcet Efficiency Under Iac?

Consider an election in which each of the n voters casts a vote consisting of a strict preference ranking of the three candidates A, B, and C. In the limit as n→∞, which scoring rule maximizes, under the assumption of Impartial Anonymous Culture (uniform probability distribution over profiles), the probability that the Condorcet candidate wins the election, given that a Condorcet candidate exists? We produce an analytic solution, which is not the Borda Count. Our result agrees with recent numerical results from two independent studies, and contradicts a published result of Van Newenhizen (Economic Theory 2, 69–83. (1992)).     

A local join counts methodology for spatial clustering in disease from relative risk models

ABSTRACT

This paper considers adaptation of hierarchical models for small area disease counts to detect disease clustering. A high risk area may be an outlier (in local terms) if surrounded by low risk areas, whereas a high risk cluster requires that both the focus area and surrounding areas demonstrate common elevated risk. A local join count method is suggested to detect local clustering of high disease risk in a single health outcome, and extends to assessing bivariate spatial clustering in relative risk. Applications include assessing spatial heterogeneity in effects of area predictors according to local clustering configuration, and gauging sensitivity of bivariate clustering to random effect assumptions.     

Bayes estimation of the binomial parameter n

Bayes estimation of the binomial parameter n based on a general prior distribution for n is studied. As special cases improper prior and Poisson prior (which is a natural choice) are considered, and formulae for the marginal and posterior distributions are obtained. It is shown that the assumption of improper priors in both p and n leads to implausible results.
