华人社会中的自谦初探

通过对典籍的梳理初步探讨了华人社会中自谦的内涵、实质和运作模式。自谦可能包涵“守弱处柔”、“卑己尊人”、“恭允克让”和“恭敬有实”四个方面。自谦的实质涉及“和合”、“远耻”、“隐显”;自谦包括“功利性”和“真诚性”两个因素,体现在“淡泊超脱—刻意功利”与“直率真诚—婉转伪饰”两个维度上。以这两个维度为基础的“谦礼”、“谦敬”、“谦卑”和“谦忍”可能是华人社会自谦的主要运作模式。     

The Effect of a Context-Specific Primed Goal on Goal Commitment and Team Performance

The effect of a context-specific prime for cooperation on goal commitment and team performance were examined. In the first experiment, the participants (n = 139) performed the Lost on the Moon simulation (Hall & Watson, 1970) individually and as a team (n = 50). The teams were randomly assigned to a condition where they were assigned the same goal. They were then primed (n = 23) through a photograph of cooperation or to the control condition (n = 27). Consistent with NASA’s directions for performing the simulation, performance was measured by how well a team performed relative to the answers of experts, namely, staff at NASA. The results showed that a primed behavioural goal to cooperate has a positive effect on team performance. These results were replicated in a second and third experiment involving a social dilemma where both a pro-social, group-centric goal and a pro-self, egocentric goal could be self-set for the amount of points to make. Thus the positive effect of a goal primed for cooperation on a team’s performance was shown to be robust even when there was an explicit mixture of cooperative and competitive incentives. This finding was replicated in a third experiment with actual money. Consistent with goal setting theory, commitment to the team’s goal moderated the primed goal-performance relationship.     

Community identity as a mediator of the relationship between socioeconomic status and altruistic behaviour in Chinese residents

Socioeconomic status is related to altruistic behaviour, but the link between them remains controversial. The present study explored the link between socioeconomic status and altruistic behaviour, as well as the psychological mechanism between them. We recruited 1,052 residents from 34 provinces in China to investigate the relationship between socioeconomic status and altruistic behaviour and the mediating mechanism. Results showed that objective socioeconomic status was positively related to altruistic behaviour. Subjective socioeconomic status was positively associated with community identity and altruistic behaviour. Community identity mediated the relationship between subjective socioeconomic status and altruistic behaviour. The findings suggest that enhancing individuals' community identity or subjective status perception can effectively increase their altruistic behaviour.     

大学生压力和睡眠质量：反刍思维和心理韧性的链式中介作用

采用大学生压力量表、反刍思维量表、青少年心理韧性量表和匹兹堡睡眠指数量表调查684位大学生(被试平均年龄为20.26岁;SD = 1.08),探讨反刍思维和心理韧性在压力和睡眠质量之间的链式中介作用。结果表明：(1)压力对睡眠质量有显著的负向预测作用;(2)压力可通过反刍思维和心理韧性的独立中介作用及反刍思维和心理韧性的链式中介作用间接预测睡眠质量。本研究揭示了压力和睡眠质量的关系及作用机制,深化了大学生压力对睡眠质量影响的研究。

通过文献检索及对43名高校校长及其直接下属的访谈,经专家讨论,编制了中国高校校长变革型领导行为量表。515份数据的探索性因素分析和461份数据的验证性因素分析结果表明,中国高校校长的变革型领导行为是五因素结构,即德行垂范、关怀激发、愿景激励、领导魅力、团结协作。问卷具有良好的信效度。回归分析结果表明,高校校长的变革型领导行为对教师组织承诺具有正向影响,其中,教师的内部动机与学校的组织氛围对二者的关系具有完全中介作用。     

Measurement Equivalence/Invariance of the Abusive Supervision Measure Across Workers From Taiwan and the United States

Growing international research interest in negative-leadership behaviors prompts the need to examine whether measures of ineffective leadership developed in the United States are equivalent across countries outside the United States. B. J. Tepper's (2000) abusive supervision measure has been used widely inside and outside the United States and merits research attention on its construct equivalence across different cultural settings. The authors conducted a series of multigroup confirmatory factor analyses to investigate the measurement equivalence of this measure across Taiwan (N = 256) and the United States (N = 389). Configural invariance was established, suggesting that both U.S. and Taiwanese samples perceive abusive supervision as a single-factor concept. Furthermore, the establishment of partial metric invariance and partial scalar invariance suggests that the abusive supervision measure is applicable to crosscultural comparisons in latent means, construct variance, construct covariances, and unstandardized path coefficients with the caution that workers from different cultures calibrate their responses differently when answering some items.     

Infiltration behaviour of water in a carbon nanotube under external pressure

The wetting behaviour and associated pressure effect of water in single-walled carbon nanotubes (SWCNTs) are investigated through molecular dynamics (MD) simulations. It is found that water molecules can enter SWCNTs via surface diffusion, and the effective infiltration rate increases with pressure. The effect of pressure on infiltration rate is highly non-linear, exhibiting characteristics of both hydrophilic and hydrophobic surfaces. There exists a nominal infiltration pressure that is dependent on the SWCNT size, above which the water flux is significantly increased.     

Energetic effects of dopants on the eutectoid decomposition of Nb–Si in situ composites

The influences of doping elements (Ti, Zr, Hf, V, Ta, Cr, Mo, W and Al) on the heats of formation of Nb, Nb₅Si₃ and Nb₃Si have been studied using first-principles pseudopotential plane-wave method based on density functional theory. Site preferences of dopants in Nb₅Si₃ and Nb₃Si intermetallics are first determined by comparing the heats of formation of the systems with different site occupations of the doping atoms. The partitionings of dopants between the equilibrium phases Nb and Nb₅Si₃ of Nb–Si in situ composites are then discussed and compared with experimental results. Phase partitioning behaviours of the alloying elements are found to depend strongly on the number of their valence electrons. By calculating the enthalpy of reaction regarding the eutectoid decomposition of Nb₃Si phase, we conclude that Ta is a Nb₃Si stabiliser while other dopants destabilise Nb₃Si at the investigated concentration.
