歧视知觉对初中生的合作倾向与行为的影响

本文通过两个研究揭示歧视知觉对初中生合作倾向与行为的影响, 研究1采用问卷法对752名初中生进行为期一年的追踪, 运用潜变量交叉滞后结构方程模型分析歧视知觉与合作倾向之间的纵向预测关系; 研究2采用动态公共物品困境实验考察歧视知觉对合作行为的影响, 以及群体类型的调节作用。结果发现：(1)初中生的歧视知觉与合作倾向存在显著负相关; T1合作倾向可负向预测T2歧视知觉, T2歧视知觉可负向预测T3合作倾向; (2)在公共物品困境前三轮投资比和贡献率上, 歧视知觉和群体类型的交互效应显著; 而在后三轮仅发现歧视知觉在投资比和贡献率上的主效应, 以及群体类型在贡献率上的主效应。以上结果表明, 歧视知觉与合作倾向之间存在纵向螺旋式影响; 歧视知觉对前期合作行为的影响受到群体类型的调节, 但随着互动时间延长, 该调节作用消失。     

逆境中何以建言?成就目标视角下员工建言韧性的形成机制与作用效果

在动态复杂的商业环境中, 员工建言对于组织发展具有重要的意义。以往的建言研究普遍认为, 当环境不支持建言时员工会减少建言行为。然而, 并非所有员工都会在逆境中放弃建言, 有的员工甚至会在逆境中表现出更多的建言行为。为了回答员工何以在逆境中持续建言这一基本问题, 探索员工在逆境中持续建言的形成机制和作用效果, 本文将首先探讨建言韧性的概念内涵, 并开发建言韧性的测量工具。然后, 以成就目标理论为基础, 对三种目标定向促进或者抑制员工建言韧性的路径和条件做出分析。最后, 探讨建言韧性对员工后续建言行为和领导者建言采纳的影响。本文回应并拓展了建言研究的前沿问题, 也为组织了解和培养员工的建言韧性提供实践启示。     

Mental Disorders Associated with COVID-19 Related Unemployment

In response to the COVID-19 pandemic, restrictions on economic activities have resulted in a sharp rise of unemployment. The purpose of this research is to explore mental disorders associated with COVID-19 related unemployment using a large, nationally representative dataset, the 2020 COVID-19 Household Pulse Survey. ANOVA with post hoc tests (Tukey HSD) are utilized to reveal the mean difference of mental disorders between various employment status, as well as between reasons of unemployment. Binary logit model is used to investigate the potential effect of different reasons of unemployment on mental disorders. Individuals who were not working during the pandemic due to involuntary reasons had higher probabilities of mental disorders than those who were working and those who voluntarily separated from work. Among respondents who were not working due to COVID-19 related reasons, respondents whose employer went out of business were the most likely to experience mental disorders. Household job uncertainty in the next four weeks positively contributed to mental disorders. Government should consider measures to contain the spread of virous while keeping as many people employed as possible. Government should also consider providing adequate financial and counseling assistance to individuals who are in the greatest need for such support.

     

入学过渡期高中新生大五人格与主观社会地位变化轨迹的关系：基于潜变量增长模型的分析

为了考察入学过渡期高中新生主观社会地位（subjective social status, SSS）的变化轨迹及人格在其中的作用,本研究对546名高一新生进行了历时4个月的4次追踪测试。基于潜变量增长模型的分析结果显示：（1）SSS呈阶段化线性增长,且个体间差异显著;（2）人格中的外倾性、宜人性、责任心和开放性均能显著预测SSS的初始水平;（3）外倾性、宜人性和神经质对SSS的第一阶段变化速度有显著预测作用。结果表明,SSS会在新生入学后1个月内初步形成,且人格与其变化轨迹有关。     

Culture and institutional agency: difference in judgments of economic behavior and organizational responsibilities

The current research tested the concept of institutional agency (IA) and its implications for laypeople's attribution patterns related to economic behaviors and organizational responsibilities. The term “institutional agency” refers to a set of lay theories about whether or not an organization can have personhood and related mental properties, such as wishes, desires, intents, and responsibility. Through three cross‐cultural studies, we found that people do form certain beliefs about IA which are similar to the legal discourse of institutional responsibility. However, there are significant cultural differences in views of IA, and the concept is more mentally salient for Americans than for Chinese. In Study 1, we distinguished institutional from group agency by showing the cultural differences on attributions in the scenario with “individual vs. group agency” and the scenario with “individual vs. institutional agency.” In Study 2, we again demonstrated the stronger salience of IA for Americans than for Chinese by including the individual, group, and institutional agencies together in one scenario. In Study 3, we further demonstrated that the concept of IA is more salient for Americans by presenting three different agents in separate scenarios. The practical implications of these cultural differences for cross‐cultural understanding and the psychological effects of economic globalization are discussed.     

隆乳术的演变与进步

隆乳术不仅可以重塑女性的形体美,而且可以增强女性的自信心,在当前具有广阔的市场。纵观隆乳术的发展演变史,从最初的注射隆乳术到自体组织隆乳术,再到当前的假体隆乳术和自体脂肪移植隆乳术,经历了“实践、认识、再实践、再认识”的多次反复。各种隆乳方式各具特色,其间既有成功的经验,又有失败的教训。针对隆乳术安全性的改进推动了隆乳术的不断向前发展。寻找一种安全有效的隆乳方式和理想的隆乳材料成为当前隆乳术发展的关键和整形外科医师关注的重点。     

我们应该“创造生命”吗？

人造细胞是现代生物科学技术中的热点问题之一,由人造细胞及其衍生出来人造生命的伦理问题也备受关注,关于是否应该继续研究人造生命,支持者和反对者之间各执其词。以克莱格·文特“创造人造细胞”事件为切入点,回顾了人造生命的历史,简要介绍人造细胞的产生过程,分析人造细胞的正面和负面影响;同时提出马克思主义哲学可以为医学伦理问题的研究提供不同的维度与角度,让人们对人造细胞产生的道德问题做出更全面的判断。     

医院重点专科发展过程阶段论

讨论医院重点专科发展过程的阶段划分及特征,对于我们在重点专科建设中正确地把握方向、恰当地评估成效和有力地予以推进都有十分重大和现实的意义。本文把医院重点专科发展过程分为科室建设、学科建设、科学建设阶段,并从功能目标、效率效益、人才队伍、场地设施、技术设备、技术特色、教学培训、科学研究、文化氛围、能级水平十个方面对各阶段的特征进行归纳描述。三个阶段各具不同内涵特征,又存在相互内在关联,具有方向性、连续性、可加速性、交叉性和包涵性等规律。

自我损耗、情绪动机对冲动决策的影响

以大学生为被试,探讨自我损耗、情绪动机对冲动决策的影响。采用2×2×2的混合实验设计,组内变量为自我损耗,组间变量为情绪动机方向和强度,使用双任务范式操作自我损耗,使用情绪动机图片启动被试的情绪动机,使用延迟折扣任务的指标k值测量冲动决策。结果发现,高趋近动机的k值大于低趋近动机,高回避动机的k值大于低回避动机。结果表明,自我损耗、情绪动机对冲动决策有明显影响。
