团队决策及其影响因素

随着组织结构的变化,团队决策为越来越多的组织所采用。该文将团队决策的研究范式概括为以下四类：社会决策图式（social decision scheme, SDS）、信息取样模型（information sampling model）、项目排序任务（ranking item task）团队以及组织中以安全优先的团队（safety priority team）;并从影响团队决策的因素,提高团队决策质量的策略等角度分别对四类团队决策的研究进行探讨,在此基础上本文对未来研究进行了展望     

自传记忆的加工机制研究进展

自传记忆是关于个人生活经验的记忆,它有悖于Ehbinghaus的记忆研究传统。在国外．90年代以来自传记忆研究已成为继内隐记忆研究后．记忆领域的又一研究热点。自传记忆加工机制的研究是认知心理学对自传记忆研究的核心领域。本文主要评析了自传记忆的知识表征．自传记忆提取机制的研究进展。目前已有的研究结论是：（1）自传记忆是以个人生活片段知识、一般事件知识和具体事件知识三种方式表征的;（2）自传记忆的提取方式主要通过生成提取和直接提取方式来实现。     

初二学生解几何应用题策略类型的研究

运用作品分析法对60份初二优秀生、中等生、差生的第一学期数学期中考试卷进行分析,发现初二不同学习水平学生解数学应用题时表现出不同的解题策略类型：优秀生的解题策略属于“俯瞰型”;中等生的解题策略属于“经验型”;差生的解题策略属于“盲试型”。     

Science, Values and the Human Dimensions

The presented paper substantiates the principle that values are an immanent component of science and any rational cognitive activity. This principle belongs to the European cultural tradition starting from the book of Genesis of the Old Testament, the values of certainty in the antique Greek philosophy and Francis Bacon's coincidence of knowledge and power. Values in science form complicated structures inconnection with different types of knowledge including “the knowledge that”, empirical evidence, various types of generalizations or rules, methods, directions, algorithms, “the knowledge how”, “the knowledge why” or other types of knowledge. Since the assignments of different types of values are the products of a decision-making, it is useful to distinguish many types of decision-making, especially semantic decision-making, information decision-making and decision-making with distinctly pragmatic dimensions. The values assignable to scientific activities and their results also include their social recognition, respect and prestige granted to knowledge and bearers of knowledge by society and social groups or communities. Knowledge generation and the rational and justified application of the achieved and acceptable impacts are also connected with decision-making procedures, values and criteria of social acceptance. This revised version was published online in August 2006 with corrections to the Cover Date.     

Symptom patterns in late luteal-phase dysphoric disorder

The symptom patterns of 180 women with prospectively confirmed late luteal-phase dysphoric disorder (LLPDD) were examined using a careful application of factor and cluster analytic techniques. Factor analysis of premenstrual change scores on 33 common premenstrual syndrome symptoms yielded four orthogonal factors that were consistent across two sets of menstrual cycle data. These were a negative affect dimension with concomitant behavioral changes, physical symptoms, agitation, and positive arousal. Cluster analysis of factor scores grouped patients into one of five symptom patterns, the most common of which is a general distress cluster, characterized by symptoms across all dimensions. The LLPDD symptom groups identified are remarkably consistent with those of earlier studies using both normative and clinic samples, and consideration of symptom pattern differences in future research may greatly increase our understanding of this disorder.     

Vocational Personality Types in College Engineering Students in Relation to Academic Achievement

This study explored whether and to what extent vocational personality types based on Holland (1994) correlate with and explain unique variance of academic success among 117 undergraduate civil engineering students by using the Self-Directed Search–Form R, 4th Edition. Findings indicated that the majority of participants’ 1st-letter code was Realistic (39.3%), 2nd-letter code was Investigative (24.8%), and 3rd-letter code was Social (21.4%), compared with Holland's 3-letter codes for civil engineering (Investigative, Realistic, Enterprising). The study also calculated the degree of congruence between personality type and occupational environment. For career counselors, the findings underscore the importance of using congruence scores to predict engineering students’ academic performance.     

Teaming up with temps: the impact of temporary workers on team social networks and effectiveness

Temporary workers offer immediate benefits to the bottom line; yet, it is unclear how incorporating temporary workers into teams affects how they function. We apply social identity theory to propose that temporary workers significantly reduce individual- and team-level networks and team effectiveness but that commitment to the leader and intergroup competition can help temporary and permanent employees work together more effectively. Using a sample of employees nested in teams (Study 1, n = 312), we found that status differences affected member interactions resulting in sparser advice and friendship networks for temporary workers compared to their permanent counterparts. At the team level (Study 2, n = 58), these team member differences or contract diversity impacted team functioning through advice networks, such that, teams with greater contract diversity had sparser networks and were less effective. Further, commitment to the leader was found to moderate the negative impact of contract diversity on advice and friendship network density. With the increasing use of temporary worker and the prevalent use of teams, these findings have broader implications for HR functions and present possible avenues to mitigate the negative consequences of temporary workers.     

急性创伤青年患者的心理健康水平与小组干预

为了探讨急性创伤青年患者的心理健康水平及小组干预对策,采用三种国际通用量表（SCL-90、HAMA、HAMD）对160例急性创伤青年患者进行测评,在给予传统心理护理的同时,进行小组干预,然后比较患者干预前后心理健康水平;并以既往同种病例为对照,比较治疗效果。结果显示,86．25％的急性创伤青年患者存在有不同程度的心理障碍。通过小组干预后,患者心理健康水平明显提高;患者的临床疗效明显改善。因此小组干预可显著改善急性创伤青年患者的心理应激水平,提高临床疗效。     

Types of \mathsf{I} -Free Hereditary Right Maximal Terms

The implicational fragment of the relevance logic “ticket entailment” is closely related to the so-called hereditary right maximal terms. I prove that the terms that need to be considered as inhabitants of the types which are theorems of T_→ are in normal form and built in all but one case from and only. As a tool in the proof ordered term rewriting systems are introduced. Based on the main theorem I define FIT_→ – a Fitch-style calculus (related to FT_→) for the implicational fragment of ticket entailment.
