本文在对"高考移民"的含义和类型进行概述的基础上,回顾了已有研究对"高考移民"原因的探讨,将其总结为中国传统文化观念的影响、地方政府及学校对经济利益的追求、各省市不同的高考录取分数线等七个方面。本文从学科研究的视角评述了已有"高考移民"原因的研究,并指出其存在的不足及未来研究的方向。     

Perceptions of Civil Servants Toward Privatization and Development: A New Exploratory Study

This study examines the perceptions of civil servants towards privatization with respect to national development. Using case studies and official interview data, it also examines the efficacy and effectiveness of privatization programs in a developing country, Bangladesh. The study rejects the conventional beliefs about the role of bureaucracies as anti-privatization by revealing that civil servants of Bangladesh have positive perceptions towards privatization with respect to national development. The study, however, finds no significant differences in the perceptions of different levels of civil servants towards privatization with respect to national development; they all share a common goal. Research demonstrates that civil servants generally believe that privatization positively affects economic, social, political and administrative development, although it negatively affects equity, fairness and social justice issues by widening the gap between the rich and the poor. Additionally, the study demonstrates that privatization is not conducive to employee empowerment.

民族院校新生心理健康水平调查

为了了解民族院校新生心理健康水平,我校采用SCL-90症状自评量表,对2004级大学生的心理健康状况进行调查。结果表明,总体上,“总分”在160分以上的人数的人占此次调查总人数的21.0%;与全国常模相比,“躯体化”因子得分显著低于全国常模,其余8个因子得分显著高于全国常模;男女生在5个因子上差异显著;不同民族之间,少数民族学生只有“精神病性”这一个因子显著高于汉族学生,其余各因子不存在显著差异。     

SNA研究的最新进展:中心框架、卫星账户和扩展研究

中心框架、卫星账户及其相关扩展问题的研究都是国民经济核算的研究内容,由于三者的研究重点与角度不同,所以,这三部分内容不是可有可无的,更不能互相替代。只有把握住国际上的最新前沿,将中心框架、卫星账户及其相关扩展问题的研究全面纳入国民经济核算范畴,才能将中国国民经济核算研究与实践推向深入。

Maximum Likelihood Estimation for the 4-Parameter Beta Distribution

This paper addresses the problem of obtaining maximum likelihood estimates for the parameters of the Pearson Type I distribution (beta distribution with unknown end points and shape parameters). Since they do not seem to have appeared in the literature, the likelihood equations and the information matrix are derived. The regularity conditions which ensure asymptotic normality and efficiency are examined, and some apparent conflicts in the literature are noted. To ensure regularity, the shape parameters must be greater than two, giving an (assymmetrical) bell-shaped distribution with high contact in the tails. A numerical investigation was carried out to explore the bias and variance of the maximum likelihood estimates and their dependence on sample size. The numerical study indicated that only for large samples (n ≥ 1000) does the bias in the estimates become small and does the Cramér-Rao bound give a good approximation for their variance. The likelihood function has a global maximum which corresponds to parameter estimates that are inadmissable. Useful parameter estimates can be obtained at a local maximum, which is sometimes difficult to locate when the sample size is small.
