师范院校学生心理素质教育综合模式的探索

本研究针对师范院校大学生心理素质的实际状况,结合心理素质的内涵,对师范院校学生心理素质教育模式进行系统的理论研究和深入的实践探索,创造出一套全新的心理素质教育的操作模式:一是加强心理学公共课建设,强化技能学习;二是建立心理咨询机构;三是建立学生心理档案,定期测量;四是开展心理素质教育专题讲座;五是发挥学生主体作用;六是积极参与社会实践,提高社会适应力;七是开展学生的自我教育。

Inverse Combinatorial Optimization: A Survey on Problems, Methods, and Results

Given a (combinatorial) optimization problem and a feasible solution to it, the corresponding inverse optimization problem is to find a minimal adjustment of the cost function such that the given solution becomes optimum.Several such problems have been studied in the last twelve years. After formalizing the notion of an inverse problem and its variants, we present various methods for solving them. Then we discuss the problems considered in the literature and the results that have been obtained. Finally, we formulate some open problems.

African American Children's Adjustment: The Roles of Maternal and Teacher Depressive Symptoms

This study examined the unique and interactive roles of mother and teacher depressive symptoms in child adjustment in 277 African American single mother‐headed families, as well as whether the associations differed depending on the age and gender of the child. Findings revealed a significant association between maternal depressive symptoms and child depressive symptoms in girls, but not boys. Moreover, the combination of higher levels of both mother and teacher depressive symptoms was associated with the highest level of child depressive symptoms and, for younger children, externalizing symptoms. The importance of considering the multiple social contexts in which children interact is discussed.     

Some computational problems related to multinomial trials

Efficient numerical algorithms are developed to evaluate several probabilities related to multinomial trials.In the first part of the paper, the probability distribution of the number of trials until the alternatives j, j = 1,… m, have occurred at least i_j times is computed. The multinomial trials involve the m alternatives l,…, m, with positive probabilities P_l-P_m of occurrence. In the second part, several aspects of a multinomial subset selection problem, discussed by S. S. Gupta and K. Nagel, are investigated.     

多种车流网络到单种车流网络的等价变换

本文讨论了多种车流网络到单种车流网络的等价变换方法。在实际的运输问题中,常会遇到多种车流的问题,采用了本方法之后,可使问题的解决变得较为简便,从而也提高了计算的效率。文中首先讨论了两种车流的情况,然后也述及一般情况,最后给出了两种车流的实际算例。     

A note on the universal optimality criterion for full rank models

The aim of this note is to suggest a revised formulation of the universal optimality criterion for full rank models as stated in Kiefer (1975). We have presented the relevant results with indications of some possible applications.     

Hardiness and the relationship between stressors and outcomes

Using a sample of 468 participants, from two organizations, this study examined direct and moderating relationships between hardiness (a composite of challenge, control, and commitment), life and work stressors, and a variety of health-related outcomes. The results indicated that hardiness did not moderate the relationship between stressors and outcomes as reported by others (e.g. Kobasa 1982a). However, hardiness did have significant direct effects on emotional and psychological factors thought to be related to personal well-being and work performance. Hardy individuals reported higher levels of job satisfaction and fewer tensions at work dun did the less hardy. In general, hardy individuals experienced a higher quality of life and a more positive affect while being more energized and less negative about life. Hardy individuals also reported fewer somatic complaints and tended to be less depressed and anxious than individuals low in hardiness. In addition, hardiness was negatively related to all four measures of life and work stress implying that hardiness may not be independent of life demands.
