组织承诺与职务投入对技术人员行为的影响

文章讨论了不同职业发展阶段条件下组织承诺和职务投入分别对工程技术人员工作绩效和离职倾向的预测效应.针对Werbel(1984)提出的只有职业发展后期组织承诺才能有效预测离职以及Keller(1997)提出的职务投入对工程师绩效不具有预测力,论文提出了不同观点.通过问卷法对210位工程技术人员进行测量发现,无论离职倾向还是工作绩效,随着职业发展,其预测变量呈现组织承诺-职务投入-组织承诺交替出现的特征.文章对交替过程中的职业发展阶段划分及不同阶段的任务特征作了进一步探讨.     

20世纪全球卫生发展的回顾与展望

20世纪人类的健康状况发生了革命性的转变,同时也面临着前所未有的挑战。疾病谱的改变及人口寿命的延长以及医疗费用的上涨仍然是困扰各国决策者的难题,卫生发展与改革任重道远。完善健康保障体系最理想的选择方案是政府为居民“购买”基本卫生服务,由国家财政和居民共同承担保险基金,普及初级卫生保健,鼓励多种形式办医,WHO确定的卫生工作目标是各成员国卫生系统改革与发展的指导方针。     

3-6年级小学生师生关系:结构、类型及其发展

本研究采用师生关系教师评定量表,由14名班主任教师对498名3-6年级学生与教师的关系进行评价.结果表明:(1)师生关系量表具有较好的信度和效度,师生关系特点主要表现在冲突性、亲密性和反应性三个维度上.(2)快速聚类分析的结果表明,3-6年级学生的师生关系可划分为3种类型:冷漠型、冲突型、亲密型,其分布比例分别为23.0%、33.7%、43.3%.(3)师生关系随学生年级增长而变化.在师生关系各维度及总分上,存在显著的年级差异.随年级的上升,积极师生关系类型的比例逐渐下降,而消极师生关系类型的比例逐步上升.     

保险推销员(职业)自我效能感量表的建构

在对保险推销员自我效能感进行理论分析、现场访谈和问卷调查之基础上,采用探索性因素分析和验证性因素分析技术,对保险推销员自我效能感的内在结构进行了探讨。结果表明,保险推销员自我效能感由八个因素构成,即：晤谈技能、仪态、毅力、情绪调节、知识掌握、计划总结、直觉判断和前期准备。在此基础上,依据心理测量学原理和方法研制了保险推销员自我效能感量表。由此,保险推销员应从这八个方面来判断自己保险推销的总体素质。     

The Development of Selective Attention in Children With Attention Deficit Hyperactivity Disorder

The influence of age on a selective attention task was studied in a sample of children with and without Attention Deficit Hyperactivity Disorder (ADHD). The impact of methylphenidate (MPH) treatment on selective attention was also investigated in the children with ADHD. Two age groups of children with ADHD and two age groups of control children were tested using a timed computer task. The task consisted of identifying visual target stimuli under various distracter conditions. Distracters varied on the basis of modality (i.e., visual, auditory, or both) and task relevance (i.e., meaningful or irrelevant). Reaction times and accuracy were measured. Children with ADHD were less efficient on the selective attention task than were children without ADHD, and older children were more efficient than younger children in both groups. Children without ADHD were influenced more by the nature of distracters than were children with ADHD. For children with ADHD, MPH improved performance overall.

Visual-Motor Integration Problems in Low Birth Weight Infants

This paper represents a review of the research that focuses on a population of strong clinical interest on a national and international scale—infants born with low birth weight (LBW). Among the numerous developmental deficits commonly associated with this group, one of the most frequently cited problems is poor fine- and visual-motor integration. In addition to the direct perceptual-motor development concern, the literature provides a reasonable case that such deficits place this population at increased risk for subnormal academic performance and difficulties with specific daily living (self-help) activities. By assessing the infant at an early age and designing specific strategies for intervention, clinical psychologists can play a major role in improving fine- and visual-motor behavior in this population.     

A global optimization approach for generating efficient points for multiobjective concave fractional programs

In this article, we present a global optimization approach for generating efficient points for multiobjective concave fractional programming problems. The main work of the approach involves solving an instance of a concave multiplicative fractional program (W̄). Problem (W̄) is a global optimization problem for which no known algorithms are available. Therefore, to render the approach practical, we develop and validate a branch and bound algorithm for globally solving problem (W̄). To illustrate the performance of the global optimization approach, we use it to generate efficient points for a sample multiobjective concave fractional program.

青少年学生自立人格自陈量表的建构

通过对前期系列研究结果的梳理,建构出了涉及个人自立与人际自立两个方面共10种特质的青少年学生自立人格结构。根据理论构想,在5次预试的基础上编制出了青少年学生自立人格量表,并对1723个有效被试进行了调查。将有效被试划分为两个样本分别进行了探索性与验证性因素分析,并根据有关结果确定了量表项目。探索性与验证性因素分析的结果都检验了青少年学生自立人格结构。最后,对青少年学生自立人格结构的特点与维度含义等问题进行了讨论
