Investigation of the Multidimensional Model of Job Insecurity in China and the USA

Il y a plus d'une décennie, Ashford, Lee, and Bobko (1989) ont développé un outil de mesure standard permettant évaluer des niveaux individuels d'insécurité au travail. Les années suivantes, des chercheurs se sont demandé si la totalité des mesures composant cet instrument était nécessaire. Nous avons donc examiné l'utilité des différentes dimensions du test multidimensionnel de l'Insécurité au travail de Ashford et al. (1989) aux Etats Unis et en Chine, en éprouvant et élargissant les conclusions antérieures. Nos résultats suggèrent qu'éliminer les dimensions "caractéristiques du travail" et "impuissance" de l'instrument multidimensionnel initial est prématuré dans les deux cultures. D'autres recherches s'avèrent donc nécessaires pour déterminer l'utilité de cet outil dans sa version complète. Les implications de nos résultats sont discutées.
Over a decade ago, Ashford, Lee, and Bobko (1989 ) developed a standard measure for those interested in assessing levels of individual job insecurity. In ensuing years, some researchers have questioned whether the entire measure is necessary. We examined the usefulness of the components of Ashford et al.'s (1989 ) multidimensional measure of job insecurity in both the United States and China, as well as replicating and extending prior findings regarding antecedents and consequences. Our results suggest that the call to eliminate job features or powerlessness from the fully composite measure of job insecurity is premature in both cultures. We call for more research on the utility of the fully operationalised measure. Implications of our findings are discussed.     

冥想使人变得平和——人们对正、负性情绪图片的情绪反应可因冥想训练而降低

虽然前人已有不少研究发现冥想具有减少个体焦虑、缓解抑郁水平等功能,并且也已经揭示了冥想促进情绪调节能力的认知神经科学机理,但对于冥想会怎样调制人们对于外部施加的正、负性情绪刺激(图片)的情绪反应尚不清楚,冥想究竟会使人们对外部施加的情绪刺激的敏感性增强还是减弱?如果冥想能够调节和缓解人们的情绪反应的话,那么,这种调节作用是“双向的”(即对正性或负性情绪刺激能产生具有不同效价方向的调节作用)还是“单向的”(即对正性或负性情绪刺激产生具有相同效价方向的调节作用)?为了检验和回答上述问题,本研究以无冥想(或相关)经验的大学生为被试,通过随机实验组、控制组前后测的实验设计,考察了冥想训练能否影响被试对于正、负性情绪图片的情绪唤起.62名大学生被试被随机分配到实验组和控制组(每组31人),实验组参与连续5天、每天20 min的冥想练习,控制组在此期间的控制任务为通常的闭眼休息.结果显示:冥想组在练习过程中的脑α波指数显著升高;与控制组相比,冥想组被试对消极图片的效价评定值显著改善,这表明冥想降低了被试对负性情绪图片的情绪反应,研究还发现了冥想降低被试对正性情绪图片的积极评价倾向,从而证明对外部施加的正、负性情绪刺激而言,冥想训练的调制作用是使人们的情绪反应趋于平和.     

Genetic influences on core self-evaluations,job satisfaction,and work stress: A behavioral genetics mediated model

In this study we investigated the mediated influence of core self-evaluations (CSE) on employee health problems via job satisfaction and work stress, and the degree to which genetic factors explain these mediated relationships. Based on data obtained from a sample of 594 Swedish twins (114 monozygotic twin pairs and 183 dizygotic twin pairs), conventional path analysis results supported the mediated effects of CSE on employee health via job satisfaction and work stress, after controlling for conscientiousness and extraversion. Behavioral genetic analyses showed significant heritability of all four variables. Moreover, we found that the mediated relationships via job satisfaction and work stress are explained by genetic factors, such that the genetic source of job satisfaction and work stress mediates the genetic influence of CSE on health problems. These results highlight the role played by genetic factors in better understanding the relationships between CSE, work attitudes, and health outcomes.

“增益”还是“损耗”?挑战性工作要求对工作-家庭增益的“双刃剑”影响

基于资源保存理论和不确定管理理论, 采用日记研究法收集81个样本10个工作日的数据, 从静态和动态两个视角, 通过明晰挑战性工作要求的不同属性(每日水平、平均水平、日间变动、波动变化), 全面检验了挑战性工作要求对工作-家庭增益的影响。研究结果表明：(1)在静态模型中, 挑战性工作要求通过工作专注度(增益路径)和放松(损耗路径)作用于工作-家庭增益, 且在个体间的平均水平模型中, 放松的中介作用更为显著; (2)在动态模型中, 挑战性工作要求的日间变动和波动变化, 均通过减少员工工作专注度和放松, 进而降低工作-家庭增益。最后, 本研究讨论了管理者应重视挑战性工作要求的双刃剑作用等实践启示。     

善恶人格的特质差序

善恶问题是人们在社会生活中的重要话题, 在对他人进行知觉时, 人们首先关心的信息是什么, 是否会对不同类型善恶特质有所权衡?研究基于人格心理学视角, 通过4个研究对该问题进行了探讨。研究首先探究了人格的道德概念激活时善恶的差异, 并以代表性、好恶度、特质度和重要性为衡量指标分别考察了不同类型善恶特质的核心程度差异。结果发现, 善恶人格的特质差序体现在两个方面：(1)善恶人格间的差序, 在人格的道德范畴中, 存在善人格的优先效应; (2)善恶人格内的差序, “善”的核心由内到外为尽责诚信、仁爱友善与包容大度、利他奉献; “恶”的核心由内到外为凶恶残忍、背信弃义与污蔑陷害、虚假伪善。研究有助于进一步理解中国人的善恶观, 为善恶领域的探究提供了新思路。     

Altered topological patterns of large-scale brain functional networks during passive hyperthermia

In this study, we simulated environmental heat exposure to 18 participants, and obtained functional magnetic resonance image (fMRI) data during resting state. Brain functional networks were constructed over a wide range of sparsity threshold according to a prior atlas dividing the whole cerebrum into 90 regions. Results of graph theoretical approaches showed that although brain networks in both normal and hyperthermia conditions exhibited economical small-world property, significant alterations in both global and nodal network metrics were demonstrated during hyperthermia. Specifically, a lower clustering coefficient, maintained shortest path length, a lower small-worldness, a lower mean local efficiency were found, indicating a tendency shift to a randomized network. Additionally, significant alterations in nodal efficiency were found in bilateral gyrus rectus, bilateral parahippocampal gyrus, bilateral insula, right caudate nucleus, bilateral putamen, left temporal pole of middle temporal gyrus, right inferior temporal gyrus. In consideration of physiological system changes, we found that the alterations of normalized clustering coefficient, small-worldness, mean normalized local efficiency were significantly correlated with the rectal temperature alteration, but failed to obtain significant correlations with the weight loss. More importantly, behavioral attention network test (ANT) after MRI scanning showed that the ANT effects were altered and correlated with the alterations of some global metrics (normalized shortest path length and normalized global efficiency) and prefrontal nodal efficiency (right dorsolateral superior frontal gyrus, right middle frontal gyrus and left orbital inferior frontal gyrus), implying behavioral deficits in executive control effects and maintained alerting and orienting effects during passive hyperthermia. The present study provided the first evidence for human brain functional disorder during passive hyperthermia according to graph theoretical analysis using resting-state fMRI.
