现实及网络社会排斥与大学生抑郁的关系:自我控制的中介作用

对1077名大学生进行调查,探讨现实、网络社会排斥和自我控制与大学生抑郁的关系。结果显示:(1)现实社会排斥与网络社会排斥在发生频率上没有显著差异;网络社会排斥、现实社会排斥、自我控制以及抑郁两两之间均呈显著正相关关系;(2)现实社会排斥不仅能够对抑郁产生直接的预测作用,而且能够通过自我控制的中介作用对抑郁产生影响;(3)网络社会排斥对抑郁的直接预测作用不显著,只能够通过自我控制的中介作用对抑郁产生影响。     

Influence of plastic strain localisation on the mechanical properties of metal matrix composites

The aim of the present study is to reveal the most critical underlying factor influencing the mechanical properties of metal matrix composites (MMCs). It is shown that the mechanical properties of MMCs are essentially governed by the degree of strain localisation during plastic deformation. In other words, the MMCs exhibit superior mechanical performance only if the strain localisation is obviously inhibited and the accumulated stresses can be effectively transferred out. The work provides a new perspective in guiding the design of next-generation high-performance MMCs by suppressing the strain localisation as far as possible.     

任务与字频对汉字情绪启动反转效应的影响

本研究使用ERP技术对比了效价判断与真假字判断两种任务形式下的汉字情绪启动效应。结果发现,在效价判断任务中高频目标字出现情绪启动的反转效应,效价不一致比一致条件下反应时短,诱发了较大的P200;低频目标字出现情绪启动的一致性效应,效价一致比不一致条件下反应时短,诱发了较大的P200与N400。真假字判断任务中高频和低频目标字均出现情绪启动的一致性效应。情绪启动的反转效应依赖于刺激材料的可通达性与注意导向,启动字与目标字的反应竞争关系导致了情绪启动的反转效应。     

Measuring the personality of Chinese: QZPS versus NEO PI-R

The response patterns of Chinese subjects to the items and facets of NEO Personality Inventory Revised (NEO PI-R) were investigated. The Big Five-factor structure underlying this instrument was not found, while a seven-factor structure, more recently proposed to represent the Chinese personality, emerged. A cross-cultural strategy was adopted to analyze these results and mechanisms through which culture influences personality, behavioral categories and specific behaviors were proposed. The results showed that the Big Seven model of Chinese personality was stable and Western personality questionnaires could not accurately measure the personality characteristics of the Chinese.

劳丹的研究传统理论对心理学研究的启示

劳丹的研究传统理论是在克服库恩“范式论”和拉卡托斯“研究纲领理论”不足的基础上建立起来的更为严密、更符合科学历史事实的理论体系,本文简要介绍了该理论并在此基础上提出了心理学研究从中得到的几点启示：心理学研究应从“以方法为中心”转向“以问题为中心”,采用概念分析等多元研究方法,以一种宽容、开放的态度来评价心理学的各种理论。     

亲子教育缺失与"留守儿童"人格、学绩及行为问题

以“留守儿童”为被试,考察其家庭环境因素、人格、学绩、行为问题之间的关系,发现“留守儿童”处在相对不良的家庭环境中;不良的家庭环境因素与不良人格特质、行为问题、学业不良高相关,且后三者密切关联,相互加剧。讨论指出：对“留守儿童”问题的干预不仅要进行行为矫治和心理辅导,而且要整合社区、学校、家庭的力量,改善其家庭环境和心理氛围,为“留守儿童”建构有效的支持系统。     

语言理解转换中非目标语言影响目标语言的时间进程

运用跨语言即时启动和延时启动范式,要求被试完成生物属性的语义判断任务,研究语言理解转换中非目标语言影响目标语言语义理解的时间进程。实验1非目标语言为英文,目标语言为中文,结果表明,无论是即时启动(t = -0.423, p = 0.676),还是延时启动(t = -0.82, p = 0.419),语义相关组与语义无关组都无显著差异。实验2非目标语言为中文,目标语言为英文,结果表明,在即时启动条件下,语义相关组显著快于语义无关组(t = -3.05, p = 0.006),但延时条件下语义相关组与语义无关组无显著差异(t = -0.63, p = 0.536)。综合两个实验结果表明,晚期熟练双语者在双语语言理解转换过程中语义的即时启动影响存在不对称性,语义相关的非目标语言中文对目标语言英文语义理解起促进作用;但是语义启动效应没有得到延时体现。     

Ecstasy use and suicidal behavior among adolescents: findings from a national survey

The relationship between ecstasy use and suicidal behavior among adolescents in the United States was examined. Data from the adolescent subsample (ages 12-17, N = 19,301) of the 2000 National Household Survey on Drug Abuse were used in the analyses. Information on adolescent substance use, suicidal behaviors, and related sociodemographic, family, and individual factors was obtained in the survey. The rate of past year suicide attempt among adolescents with lifetime ecstasy use was almost double that of adolescents who had used other drugs only, and nine times that of adolescents with no history of illicit drug use. In multinomial logistic regression analyses controlling for related factors, the effect of ecstasy use remained significant. Adolescent ecstasy users may require enhanced suicide prevention and intervention efforts.     

台湾地区姑息医学制度的建立及法律实践

姑息治疗在提高晚期癌症患者生活质量、实施临终关怀、给予病人及其家属全面周到的照顾诸方面起着重要作用.在台湾,已为姑息治疗立法并实施了10年,积累了丰富的经验.这项法律本身及其细则、附件等配套文件使姑息治疗更加规范可行.研究规范的姑息治疗及台湾的相关法律可以帮助我们更好的理解姑息治疗的理念,帮助发展大陆同道构建有效实用的姑息治疗体系.
