The Moderating Effect of Core Self‐Evaluations on the Relationships between Job Attitudes and Organisational Citizenship Behavior

Several studies in the organisational citizenship behavior (OCB) literature have focused on the main effects of employee dispositions and job attitudes. The current study builds upon previous findings by examining whether core self‐evaluations (CSE) moderate the relationship between job attitudes and OCBs. Consistent with our hypotheses and with the notion that CSE contributes to one's general level of initiative and self‐confidence, data collected from 200 New Zealand workers found that the job attitude–OCB relationship was stronger for workers who were high in CSE than for workers who were low in CSE.     

家庭功能和生存质量对学生社会责任心的影响：普高生与职高生的比较

采用回归分析和结构方程建模技术探讨了708名普通高中和职业高中学生的家庭功能、生存质量和社会责任心的差异及其关系。结果发现：（1）普通高中学生的家庭功能、生存质量和社会责任心均显著优于职业高中学生;（2）普高、职高学生的家庭功能和生存质量对其社会责任心的预测效应不尽一致,普高学生社会责任心受家庭功能亲密度和适应性两维度及生存质量心理功能和社会功能两维度的复合影响,而职高学生社会责任心主要受家庭功能亲密度及生存质量的社会功能维度的影响;（3）普高学生的家庭功能通过中介变量生存质量间接影响社会责任心,而职高学生的家庭功能直接影响社会责任心和生存质量。     

Post-training intra-basolateral amygdala infusions of norepinephrine block sevoflurane-induced impairment of memory consolidation and activity-regulated cytoskeletal protein expression inhibition in rat hippocampus

Considerable evidence indicates that the noradrenergic system of the basolateral amygdala (BLA) participates in the consolidation of various types of emotionally arousing memories. We previously reported that administration of an anesthetic-dose of sevoflurane immediately after continuous multiple-trail inhibition avoidance (CMIA) training impaired memory consolidation. This experiment investigated whether posttraining noradrenergic activation of the BLA is sufficient to reverse the memory impairing effect of sevoflurane. Adult male Sprague-Dawley rats received bilateral injections of norepinephrine (NE 0.3, 1.0, or 3.0 μg/0.5 μl) or normal saline (NS 0.5 μl) immediately after training in a CMIA paradigm. Subsequently, the rats were exposed to sevoflurane (2% inspired) or air for 2h. Norepinephrine produced a dose-dependent enhancement of memory consolidation on a 24-h retention test. The highest dose of NE tested (3.0 μg/0.5 μl) blocked sevoflurane-induced impairment of memory consolidation and reversed the inhibitory effect of sevoflurane on activity-regulated cytoskeletal protein (Arc) expression in the hippocampus 2h after training. These findings provide evidence that the mechanism mediating the memory-impairing effect of sevoflurane involves a network interaction between the BLA noradrenergic system and modulation of Arc protein expression in the hippocampus.     

动觉监督早期介入对动作技能形成的影响

通过人工动作技能项目和典型职业操作技能项目的训练活动,研究了动觉监督早期介入对动作技能形成的影响,结果表明早期进行动觉监督训练可以更为充分、有效地发挥动觉监督的作用,提高动作技能形成的成绩和效率。据此讨论了“视觉为主转化为动觉为主”监督机制观点的局限性,认为自觉的职业操作技能训练活动无须遵循这一结论;提出了含有动觉训练的职业操作技能训练模式。     

心理疾病污名形成理论述评

心理疾病污名是加诸于患者身上的耻辱标记,妨碍患者的治疗和康复。心理疾病污名的成因理论包括功能主义和生物文化两个派别,污名的发展模型解释了污名的形成过程,身份威胁模型对污名的作用机制进行了阐述。通过抗议、教育和接触可以有效地减少污名。在中国开展相关研究应注重分析传统文化、心理疾病类型与污名的关系,探讨各种减少污名策略的可行性     

对新员工入职期望变化的一项纵向研究

通过对419名企业新员工入职期望的纵向研究,并运用LGM分析,结果表明：①在组织社会化初期,新员工入职期望的变化呈独特规律,即,工作期望线性下降,团队和企业期望的变化呈不定义曲线形式;②新员工入职期望各维度的变化率都存在显著的个体差异,但仅工作期望初始状态的个体差异显著;③新员工入职期望各维度的初始状态和变化速度之间都存在显著的正相关。由本研究而引发的诸如个体差异的预测因素等问题,还有待进一步研究     

两种估计多维测验合成信度置信区间方法比较

有两种方法可以估计多维测验合成信度的置信区间：Bootstrap法和Delta法.本文用模拟研究比较这两种方法,结果发现,Delta法与Bootstrap法得到结果的差异很小.因为Bootstrap法得到的是实证结果,通常被认为是真值的反映,而Delta法比Bootstrap法简单得多,所以可以用Delta法估计合成信度的置信区间.举例演示如何计算多维测验的合成信度以及用Delta法计算其置信区间.     

A Comparison of General and Work‐specific Personality Measures as Predictors of Organizational Citizenship Behavior

The current study compared general and work‐specific measures of personality as predictors of organizational citizenship behavior (OCB). Consistent with the literature on frame‐of‐reference effects in personality assessment, two of the Five Factor Model dimensions – agreeableness and conscientiousness – were significantly related to OCB. Use of a frame of reference that is conceptually relevant to the criterion led to increased validity as a result of the decrement in between‐subject variability and within‐subject inconsistency. Results indicated that work‐specific personality yielded significant incremental relationships with OCB even after general personality is controlled. Finally, regression analyses found that the incremental variance predicted by work‐specific personality decreased as the degree of between‐subject variability and within‐subject inconsistency increased. Overall, the results suggest that there are benefits to considering the work‐specific measure of personality in the prediction of OCB.     

积极情绪提高背景线索学习的适应性

背景线索的学习缺乏适应性, 这种缺乏表现在两个方面：其一是难以在已习得的场景表征上捆绑一个新目标位置(Re-learning), 也就是场景表征的更新受阻; 其二是在习得一组场景表征后, 难以学习另一组全新场景(New-learning)。研究表明, 在旧场景表征上捆绑一个新目标位置的能力可能与注意范围大小有关, 而学习全新场景则需要重置学习功能。积极情绪可以有效扩大注意范围, 并改善对旧有认知模式的固着, 因此积极情绪启动将有可能提升背景线索学习的适应性。本研究采用效价为中性和积极的情绪性图片来启动对应的情绪, 探索旧场景捆绑新目标位置时和学习全新场景时, 背景线索的学习情况, 验证积极情绪是否可以提高背景线索学习中的适应性。实验发现, 积极情绪无法促进旧场景上捆绑新目标位置的背景线索学习(Re-learning), 但是可以促进全新场景的学习(New-learning)。该结果说明, 积极情绪可以提高被试的场景学习能力进而促进对全新场景的学习, 却无法减少由表征相似性引起的旧表征的自动检索, 进而无法改善旧表征的更新过程。     

工作时间与工作绩效的非线性关系：一项元分析

基于42篇文献的64项独立研究, 总样本量为22843人的数据, 对工作时间与工作绩效的非线性关系进行了元分析。结果发现：(1)工作时间与任务绩效、关系绩效之间存在显著的倒U型关系; (2)国家类型的调节作用显著：相对于西方欧美国家, 工作时间与任务绩效、关系绩效的倒U型关系在中国更为显著; (3)产业类型的调节作用显著：相对于劳动、资本密集型产业, 工作时间与任务绩效的倒U型关系在知识密集型产业中更为显著; (4)年龄的调节作用显著：相对于高年龄水平, 工作时间与任务绩效的倒U型关系在低年龄水平群体中更为显著; (5)性别的调节作用显著：相对于低男性比例, 工作时间与关系绩效的倒U型关系在高男性比例群体中更为显著。结果不仅基于元分析厘清了工作时间与工作绩效的倒U型关系效应, 而且为劳动法中工时规定(例如周均工作时间不超过44小时)的合理性提供了科学依据, 警示组织注意工作时间对工作绩效的“过犹不及”效应。
