Ferris and colleagues defined political skill in organizations as "the ability to effectively understand others at work and to use such knowledge to influence others to act in ways that enhance one's personal and/or organizational objectives." In this study, the psychometric properties of a Chinese translation of the Political Skill Inventory were investigated, supporting construct, convergent, discriminant, and criterion validities. The results suggested that the Chinese translation retained a four-factor structure. Political skill was positively correlated with self-monitoring, conscientiousness, political savvy, emotional intelligence, extraversion, agreeableness, and proactive personality, and was negatively correlated with trait anxiety and external locus of control. After controlling for age, sex, and job tenure, political skill was predictive of task performance, work contribution, and interpersonal help. 相似文献

Source memory refers to mental processes of encoding and making attributions to the origin of information. We investigated schematic effects on source attributions of younger and older adults for different schema-based types of items, and their schema-utilization of judgments of learning (JOLs) in estimating source memory. Participants studied statements presented by two speakers either as a doctor or a lawyer: those in the schema-after-encoding condition were informed their occupation only before retrieving, while those of schema-before-encoding were presented the schematic information prior to study. Immediately after learning every item, they made judgments of the likelihood for it to be correctly attributed to the original source later. In the test, they fulfilled a task of source attributing. The results showed a two-edged effect of schemas: schema reliance improved source memory for schema-consistent items while impaired that for schema-inconsistent items, even with schematic information presented prior to encoding. Compared with younger adults, older adults benefited more from schema-based compensatory mechanisms. Both younger and older adults could make JOLs based on before-encoding schematic information, and the schema-based JOLs were more accurate in predicting source memory than JOLs made without schema support. However, even in the schema-after-encoding condition, older adults were able to make metacognitive judgments as accurately as younger adults did, though they did have great impairments in source memory itself. 相似文献

A new Mg–Sn–Zn based alloy modified with a small amount of Ag exhibits a significantly higher aging peak than that of the base alloy and at a considerably shorter aging time. The enhanced aging response of the Ag-modified alloy is ascribed to the precipitation of densely distributed MgZn2 needles and Mg2Sn plates stimulated by the Ag. A wide and low plateau behind the hardness peak could be associated with rod-shaped precipitates of the orthorhombic Mg54Ag17 phase, aligned with the hexagonal axis of the Mg matrix. 相似文献

The resource-based model of self-regulation provides a pessimistic view of self-regulation that people are destined to lose their self-control after having engaged in any act of self-regulation because these acts deplete the limited resource that people need for successful self-regulation. The cognitive control theory, however, offers an alternative explanation and suggests that the depletion effect reflects switch costs between different cognitive control processes recruited to deal with demanding tasks. This account implies that the depletion effect will not occur once people have had the opportunity to adapt to the self-regulatory task initially engaged in. Consistent with this idea, the present study showed that engaging in a demanding task led to performance deficits on a subsequent self-regulatory task (i.e. the depletion effect) only when the initial demanding task was relatively short but not when it was long enough for participants to adapt. Our results were unrelated to self-efficacy, mood, and motivation. 相似文献

为探讨压力事件对初中生抑郁的影响以及网络使用动机和网络使用强度在其中的作用,采用生活事件量表,网络使用动机量表,网络使用强度量表和流调中心用抑郁量表对武汉市内两所中学的913名初中生进行调查。结果发现:(1)压力事件与网络使用动机、网络使用强度和抑郁均呈显著正相关; (2)压力事件正向预测网络使用动机与网络使用强度,网络使用动机正向预测网络使用强度,网络使用强度正向预测抑郁; (3)网络使用动机中,社会补偿动机正向预测抑郁,而好友联系动机与休闲娱乐动机负向预测抑郁; (4)压力事件通过网络使用动机和网络使用强度的链式中介作用影响抑郁。研究结果强调压力事件不仅可以直接影响初中生抑郁,还可以通过网络使用动机和网络使用强度间接影响初中生抑郁。 相似文献

Compared to non-Hispanic whites, Hispanic adolescents in the U.S. report higher rates of several mental, emotional, and behavioral problems such as substance use, sexual risk behaviors, and internalizing and externalizing problems. There is evidence of common pathways in the development of mental, emotional, and behavioral problems with certain subgroups of Hispanic adolescents being at greater risk. In the present article, we report analysis of baseline data for 959 Hispanic adolescents who participated in one of two randomized controlled trials evaluating a family-based preventive intervention. Utilizing latent class analysis, we identified subgroups of Hispanic adolescents based on socio-ecological risk and protective factors (e.g., parent–adolescent communication, parental involvement in school). Three distinct socio-ecological risk subgroups (high, medium, and low risk) were identified and exhibited significant differences from each other across a majority of socio-ecological risk and protective factors. Adolescents in higher socio-ecological risk subgroups reported greater mental, emotional, and behavioral problems across all outcomes. Individual comparisons revealed significant differences between the low socio-ecological risk group and both the medium and high socio-ecological risk group in lifetime alcohol use, smoking, and sex, as well as internalizing and externalizing problems. Implications for intervention include focusing on specific risk subgroups and targeting shared risk and protective factors rather than specific mental, emotional, and behavioral outcomes. 相似文献
