Personality and neurochemicals in the human brain:A preliminary study using^(1)H MRS

Chinese Science Bulletin 2005年第20期50卷 2318-2322页

作者： xu shiyong PENG Danling JIN Zhen LIU Hongyan YANG Jie School of Labor relations and human resources Renmin University of China Beijing 100872 China State Key Laboratory of Cognitive Neuroscience and Learning Beijing Normal University Beijing 100875 China Center for fMRI and Department of Radiology 306 Hospital Beijing 100101 China

To investigate the neuro-biological bases of introversion-extraversion personality traits, the concentra- tion of four neurochemicals (Cho, mI, α-Glx and NAA) in anterior cigulate gyrus between normal extroverts and in- troverts were examined using non-invasive 1H MRS tech- nique. Our study revealed that introverts have significantly higher level of α-Glx, Cho and mI in the anterior cingulate gyrus than extroverts. This result provides new evidence that the anterior cingulate gyrus is related to personality traits partly in support of Eysenck’s supposition that introverts have higher arousal level than extroverts. Moreover, this result offers neurochemical data for psychobiological theo- ries of personality.

Transformati on al leadership and employee voice: an affective perspective

This study aims to examine the effect of transformational leadership on employee voice behavior. Specifically, this study investigates the mediating role of positive affect in linking sformational leadership with voice and the moderating role of over-qualification in influencing the mediation of positive affect. In particular, a twowave survey was con ducted. A sample of 271 participa nts complete a questionnaire measuring tran sformati on al leadership, positive affect and various demographic variables in the first wave. Then, they complete a second questionnaire measuring perceived over-qualification and voice behavior 2 weeks later. We conduct a series of multiple regression analyses to test the model. The results show that positive affect partially mediated the relationship between transformational leadership and employee voice behavior. Over-qualification moderated the relationship between positive affect and voice. In addition, moderated mediation analyses reveal that positive affect mediates the relationship between transformational leadership and voice only for highly over-qualified employees. This study investigates a new method linking transformational leadership and voice from an affective perspective by finding the mediating effect of positive affect. We also verify the role of "energized to" process in shaping proactive behaviors. Finally, this study examines the boundary conditions of the effect of positive affect on voice.

Is Process as Important as Outcome？ Empirical Evidence from the Chinese Context

Frontiers of Business Research in China 2014年第4期8卷 529-549页

Although the relationship between pay level and pay satisfaction has been verified as one of the most robust relationships in the literature of pay satisfaction, scholars have not yet reached an agreement regarding its underlying mechanisms. The present paper aims to investigate the link between absolute pay level and pay level satisfaction by introducing both distributive and procedural fairness perceptions as mediators in accordance with fairness heuristic perspective. A sample of 298 employees from various types of organizations completed a survey, and a series of models were compared to evaluate if the hypothesized theoretical model fits our data. We also constructed bias-corrected bootstrap confidence intervals to test the hypothesized mediation effects. The suggested theoretical model is supported, and future research directions are discussed.

基于资源保存理论,文章探索了时间窃取行为的过犹不及效应,分析其如何通过恢复体验对创新行为产生影响,以及正念的调节作用。通过对情景回顾实验的182份样本和三轮问卷调研的503份领导−员工配对数据进行统计检验,结果发现:(1)时间窃取与恢复体验呈倒U型关系,并进一步对创新行为产生影响;(2)正念调节了时间窃取通过恢复体验对创新行为的影响,即员工的正念水平越高,时间窃取对恢复体验的影响以及通过恢复体验对创新行为的间接作用越强。文章发现时间窃取可以作为一种工作内恢复形式影响员工的恢复体验和创新行为,这一观点丰富了时间窃取相关文献,拓展了工作内恢复的效果和机制研究,同时也为管理员工“摸鱼”提供了实践启示。

Efficient production of transgenic chickens using self-inactive HIV-based lentiviral vectors

Current Zoology 2009年第5期55卷 383-387页

We demonstrated the simple and effective production of transgenic chickens, in which the enhanced green fluorescence protein （EGFP） was expressed by using third-generation self-inactive HIV-based lentiviral vectors. In our experiments, lentiviruses were injected into 204 fertilized eggs, from which 30 （15%） chickens were hatched. The exogenous gene was detected in the genomes of 16 out of 30 （53%） chickens. The green fluorescence signal was observed directly in various body parts, and was particularly significant in the testes. The transgenes were also found in the offspring of these chickens. The results indicate that HIV-based lentiviral vectors can be used to generate transgenic birds economically and effectively [ Current Zoology 55 （5）： 383 - 387,2009].

尽管已有研究开始探讨亲社会违规行为的影响因素,但从领导风格角度探究亲社会违规行为的文献并不多见。本研究依据社会信息加工理论,探讨了道德领导对员工亲社会违规行为的影响。通过对241名员工两时点问卷调查结果的分析表明:道德领导对亲社会违规行为具有显著正向影响;心理安全感和工作自主性在两者之间起中介作用;冒险特质调节了工作自主性与亲社会违规行为之间的关系。本研究揭示了道德领导影响员工亲社会违规行为的作用机制及其边界条件,这对提升组织管理效率,引导组织进行管理制度创新具有重要价值。

基于道德许可理论的道德凭证机制以及道德一致性的理论线索,探究了在职场排斥调节作用下以及在感知的建设性变革责任的抑制性调节作用下,建言行为通过心理权利影响政治行为的过程。对555名员工及其上司进行问卷调查,结果显示,在职场排斥作为边界条件影响下的建言行为通过心理权利的中介作用正向影响政治行为,而感知的建设性变革责任作为抑制性边界条件负向调节心理权利的这种中介关系。研究结果从理论和实证上解释了职场排斥是激发建言行为通过心理权利产生道德凭证效应的边界条件,而感知的建设性变革责任作为边界条件能够抑制这种效应的发生。
