论马克思主义中国化与中国化马克思主义

中国共产党先进性建设的一个重要特点和优点,就是把思想理论建设始终放在优先地位。马克思主义是党的指导思想。马克思主义有狭义和广义之分。85年来党不仅把马克思主义中国化,而且创造了中国化马克思主义,从而使党在思想理论上永葆先进性,并领导中国人民不断地从胜利走向新的胜利。     

Optimal design in average for inference in generalized linear models

This paper considers the problem of optimal design for inference in Generalized Linear Models, when prior information about the parameters is available. The general theory of optimum design usually requires knowledge of the parameter values. These are usually unknown and optimal design can, therefore, not be used in practice. However, one way to circumvent this problem is through so-called “optimal design in average”, or shortly, “ave optimal”. The ave optimal design is chosen to minimize the expected value of some criterion function over a prior distribution. We focus our interest on the aveD _A-optimality, including aveD- and avec-optimality and show the appropriate equivalence theorems for these optimality criterions, which give necessary conditions for an optimal design. Ave optimal designs are of interest when e.g. a factorial experiment with a binary or a Poisson response in to be conducted. The results are applied to factorial experiments, including a control group experiment and a 2×2 experiment.     

公司治理与盈余管理:基于上市公司的实证分析

作为代理成本的一部分,盈余管理会损害投资者的利益。以修正的Jones模型估算我国上市公司的盈余管理情况、并利用南开大学公司治理指数2003-2005年的面板数据对上市公司治理状况与盈余管理进行的实证分析表明公司治理的完善会显著降低上市公司盈余管理水平,并且这种降低主要是由于董事会、监事会、信息披露以及利益相关者等公司治理机制发挥作用的积极结果。这一研究结论具有一定的稳健性。     

教师职业生涯高原结构模型的建构

教师职业生涯高原是教师在其职业生涯发展的某一阶段中出现的职业进步如晋升、流动等的停滞所引发的心理与行为状态。它与教师个体的职业经历有着必然的联系。通过对中小学教师的开放式问卷调查结果的编码分析，揭示出教师职业生涯高原是由内容高原、趋中高原和层级高原及其子系统组成的一个多维度、多层次的结构系统。     

蒙代尔——弗来明模型在中国的扩展分析

蒙代尔-弗来明模型的理论和结论已经逐渐成为各国制定宏观经济政策的基础。但是因为中国的经济体制和实际情况与蒙代尔-弗来明模型中的基本假设不完全符合,将模型的结论简单地作为制定宏观调控政策的决策依据是不够的。文章通过对中国多年实证数据的检验,建立了一个中国的蒙代尔-弗来明模型,研究了在中国特殊的情况下蒙代尔-弗来明模型的运用。     

On measuring sensitivity to parametric model misspecification

In settings where parametric inference is inconsistent under model misspecification, the discrepancy between correct and misspecified inferences is compared with the discrepancy between correct and misspecified models. To make the comparison tractable, large sample and small misspecification approximations are employed. The ratio of the approximate discrepancy between inferences to the approximate discrepancy between models is regarded as a relative measure of sensitivity to model misspecification. The maximum ratio over a family of correct distributions is determined as a measure of worst case sensitivity. As well, the distribution producing this maximum can be examined, to see how a particular combination of a parametric family and estimand is susceptible to model misspecifications.

The moderating role of social support in Karasek's job strain model

This paper examines whether social support is a boundary-determining criterion in the job strain model of Karasek (1979). The particular focus is the extent to which different sources of social support, work overload and task control influence job satisfaction, depersonalization and supervisor assessments of work performance. Hypotheses are tested using prospective survey data from 80 clerical staff in a university setting. Results revealed 3-way interactions among levels of support (supervisor, co-worker, non-work), perceived task control and work overload on levels of work performance and employee adjustment (self-report). After controlling for levels of negative affect in all analyses, there was evidence that high levels of supervisor support mitigated against the negative effects of high strain jobs on levels of job satisfaction and reduced reported levels of depersonalization. Moreover, high levels of non-work support and co-worker support also mitigated against the negative effects of high strain jobs on levels of work performance. The results are discussed in terms of the importance of social support networks both at, and beyond, the work context.     

Bayes factors based on test statistics

Summary.  Traditionally, the use of Bayes factors has required the specification of proper prior distributions on model parameters that are implicit to both null and alternative hypotheses. I describe an approach to defining Bayes factors based on modelling test statistics. Because the distributions of test statistics do not depend on unknown model parameters, this approach eliminates much of the subjectivity that is normally associated with the definition of Bayes factors. For standard test statistics, including the χ ²-, F -, t - and z -statistics, the values of Bayes factors that result from this approach have simple, closed form expressions.
