民族平等团结思想与全面建设小康社会

本文从历史发展的角度分别论述了中国共产党三代领导集体对马克思主义民族平等团结思想的继承和发展,指出十六大提出的全面建设小康社会的奋斗目标是在马克思主义与时俱进、理论创新的精神实质下对民族平等团结思想的进一步丰富和发展,认为在新世纪新阶段继续坚持民族平等、维护民族团结,巩固社会主义新型民族关系,对实现全面建设小康社会的宏伟目标均有着重要的理论意义和现实意义。     

西藏人口结构现状的描述性研究

人口结构的社会学描述性研究是社会静态分析的终点,也是社会动态分析的起点。文章通过对西藏人口的性别结构、年龄结构、地域结构、经济结构以及社会结构的社会学描述,使西藏过去人口行为和变动的结果清晰化,并提出了由西藏人口结构现状反映出的高龄、婚姻挤压、二元分化以及女性教育等问题。

Stochastic comparisons on sample extremes of dependent and heterogenous observations

Stochastic comparison on order statistics from heterogeneous-dependent observations has been paid lots of attention recently. This paper devotes to investigating the ordering properties of order statistics from dependent observations. We derive the usual stochastic order for sample minimums and the second smallest order statistic, the dispersive order and the star order for minimums of samples having proportional hazards and Archimedean survival copulas. Similar ordering results are also obtained for maximums and the second largest order statistic of samples having proportional reversed hazards and Archimedean copulas. Several examples illustrating the main results are presented as well.     

Bayesian t-tests for correlations and partial correlations

In this paper, we develop Bayes factor based testing procedures for the presence of a correlation or a partial correlation. The proposed Bayesian tests are obtained by restricting the class of the alternative hypotheses to maximize the probability of rejecting the null hypothesis when the Bayes factor is larger than a specified threshold. It turns out that they depend simply on the frequentist t-statistics with the associated critical values and can thus be easily calculated by using a spreadsheet in Excel and in fact by just adding one more step after one has performed the frequentist correlation tests. In addition, they are able to yield an identical decision with the frequentist paradigm, provided that the evidence threshold of the Bayesian tests is determined by the significance level of the frequentist paradigm. We illustrate the performance of the proposed procedures through simulated and real-data examples.     

社会认知信息加工模型在儿童攻击性行为研究中的应用

社会认知信息加工模型是分析和解释儿童攻击性行为产生原因的一种有效理论模型。通过这一模型,可以清晰地分析儿童在社会情境中处理问题时所采用的信息加工步骤,并从中发现攻击性儿童与非攻击性儿童在这些步骤中存在的差异。而生理因素、情感因素、生活环境因素、同伴关系和性别差异等,都是儿童社会认知信息加工过程的重要影响因素。本文试就儿童攻击性行为的社会认知信息加工过程、特征,以及儿童社会信息加工过程的诸种影响因素,作一较为详细的论述。     

Linear scalar-on-surface random effects regression models

Many research fields increasingly involve analyzing data of a complex structure. Models investigating the dependence of a response on a predictor have moved beyond the ordinary scalar-on-vector regression. We propose a regression model for a scalar response and a surface (or a bivariate function) predictor. The predictor has a random component and the regression model falls in the framework of linear random effects models. We estimate the model parameters via maximizing the log-likelihood with the ECME (Expectation/Conditional Maximization Either) algorithm. We use the approach to analyze a data set where the response is the neuroticism score and the predictor is the resting-state brain function image. In the simulations we tried, the approach has better performance than two other approaches, a functional principal component regression approach and a smooth scalar-on-image regression approach.     

Inferences for a Partially Varying Coefficient Model With Endogenous Regressors

In this article, we propose a new class of semiparametric instrumental variable models with partially varying coefficients, in which the structural function has a partially linear form and the impact of endogenous structural variables can vary over different levels of some exogenous variables. We propose a three-step estimation procedure to estimate both functional and constant coefficients. The consistency and asymptotic normality of these proposed estimators are established. Moreover, a generalized F-test is developed to test whether the functional coefficients are of particular parametric forms with some underlying economic intuitions, and furthermore, the limiting distribution of the proposed generalized F-test statistic under the null hypothesis is established. Finally, we illustrate the finite sample performance of our approach with simulations and two real data examples in economics.     

案例教学中学生参与度及其影响因素研究——以工商管理本科生为例

学生参与度是案例教学效果得以保障的重要影响因素。研究通过问卷调查的方式进行,问卷分析结果表明,在案例教学过程中,学生大多能够认真阅读案例,但是在加入到讨论小组、主动发表自己观点和与同学辩论这三个步骤中参与程度都偏低;SPSS软件分析结果显示,影响学生参与案例教学的因素可分为五类：课堂气氛、学生自身因素、案例的难度因素、案例的新颖性和典型性因素和沟通因素。
