Flexible regression modeling

The author proposes a new method for flexible regression modeling of multi‐dimensional data, where the regression function is approximated by a linear combination of logistic basis functions. The method is adaptive, selecting simple or more complex models as appropriate. The number, location, and (to some extent) shape of the basis functions are automatically determined from the data. The method is also affine invariant, so accuracy of the fit is not affected by rotation or scaling of the covariates. Squared error and absolute error criteria are both available for estimation. The latter provides a robust estimator of the conditional median function. Computation is relatively fast, particularly for large data sets, so the method is well suited for data mining applications.     

我国政府不能放弃组织公有经济的职能

政府参与组织实体经济,是社会经济发展规律的内在要求,被社会主义市场经济的实践证明更能促进社会生产力的发展,由建立以公有制为主体的基本经济制度所决定。为此,我国政府要主动担责,不怕被问责,不怕被指责。

论意志在认识中的作用

意志在认识中具有多方面的作用 ,其中最基本的是 :定向作用、控制作用和调节作用。意志在认识中的能动作用是在实践中产生和发展的。主体意志的变化与其所处的外部社会文化环境的变化并非绝对同步的。主体意志具有自身的相对独立性。单独拓展对主体意志认识中的作用的研究 ,具有很大的必要性。

社会管理与政府能力建构

作为主责人类权威性价值分配和管理公共生活的组织体系,政府的能力建构永远与其价值分配导向确立、职能实现以及治理绩效紧密联系在一起。一方面,适应社会发展要求和回应公共问题挑战,能力建构为政府破解各种困局、满足民众需求、履行公共职责提供了有力的改革思路和策略;另一方面,政府能力建构的方向定位体现了政府合法性的基础和依据。中国政府正面对着前所未有的强化社会管理职能的诉求,实现社会管理职能直接关系到中国社会的成功转型,而政府建构并发展与社会管理责任相适配的能力,是完成职能,达成绩效必需的基础条件。基于此,本文阐述了政府能力建构内涵、社会管理中政府能力建构的方向与依据、社会管理三个层次的政府能力建构等三个问题。     

A procedure for testing the equality of k dependent correlation coefficients

A procedure is proposed for testing the equality of k dependent correlation coefficients. The procedure is simulated utilizing Monte Carlo techniques; and, a method for post hoc probing is also suggested.     

Gendered Egos: Attitude Functions and Gender as Predictors of Homonegativity

This study used a correlational design with a sample of university students to clarify the relationships between attitude functions and homonegativity with respect to gender. Classic work on attitude functions posits that attitudes serve psychological needs for the attitude holder. Herek (1986b) adapted this theory to explain attitudes toward homosexuality. Herek (1987) identified four functions: ego-defensive (defense of threats to the self), value-expressive (expression of key values), social-expressive (expression of important social norms), and experiential (based on past experiences). Results suggested that men were more likely to attribute their attitudes to the ego-defensive function. Men and women were equally likely to attribute their attitudes to the experiential function. The ego-defensive function was the best predictor of homonegativity for men and women, whether they held generally positive or generally negative attitudes toward homosexuality. The experiential function did not predict homonegativity. Participants tended to be neither very homonegative nor very ego-defensive.
