The personality factor of extraversion has been associated with performance in some occupations (e.g., sales), and it has been one of the most consistent personality predictors of leadership. Recent research indicates that extraversion could have a non-linear relation with performance. At the same time, many researchers have contended that scholars should utilize measures of personality narrower than factors and that the bandwidth and relevance of personality should fit both the criterion and the context of a study. We argue and find that by examining an aspect of extraversion (i.e., social potency) in a particular vocational context (i.e., enterprising job demands), non-linear, asymptotic (diminishing marginal benefits) effects will be demonstrated on a relevant type of performance (i.e., enterprising job performance). We review implications, limitations, and avenues for future research. 相似文献

In newly formed groups, informal hierarchies emerge automatically and readily. In this study, we argue that emergent group hierarchies enhance group performance (Hypothesis 1) and we assume that the more the power hierarchy within a group corresponds to the task‐competence differences of the individual group members, the better the group performs (Hypothesis 2). Twelve three‐person groups and 28 four‐person groups were investigated while solving the Winter Survival Task. Results show that emerging power hierarchies positively impact group performance but the alignment between task‐competence and power hierarchy did not affect group performance. Thus, emergent power hierarchies are beneficial for group performance and although they were on average created around individual group members' competence, this correspondence was not a prerequisite for better group performance. 相似文献

The Helsinki Declaration is a very important document regarding the protection of patients’ rights in clinical trials and
one of the fundamental sources of operational principles for every ethics committee. Although they have been updated, the
international guidelines for ethics committees continually fail to address certain issues pertaining to the protection of
patients’ rights in clinical trials. These issues include, most significantly, the method of electing ethics committees (a
free, secret ballot should be preferred to direct appointment), the avoidance of conflict of interest during the election
of ethics committee members, and the necessary insurance coverage for the participants of clinical trials. Polish law should,
on the other hand, be developed in such way as to not limit the effectiveness of ethics committees in protecting patients’
rights in clinical trials. The ideal solution would be to draft a uniform law concerning not only clinical trials, but all
medical experiments. The opinions of experts who have been reviewing medical research projects for several years may prove
to be especially valuable in this setting.
This paper was presented at the 6th International Bioethics Conference on the subject of ‘The Responsible Conduct of Basic
and Clinical Research’, held in Warsaw, Poland, 3–4 June 2005.

Goal-setting effects on selected performance behaviors of 5 collegiate rugby players were assessed over an entire competitive season using self-generated targets and goal-attainment scaling. Results suggest that goal setting was effective for enhancing task-specific on-field behavior in rugby union. 相似文献

Autonomy and Nondefensiveness 总被引:1,自引:0,他引:1
Three experimental studies tested whether a priming procedure intended to activate an autonomy orientation would lead to nondefensiveness
and enhanced performance, whether activated control orientation would lead to higher defense and impaired performance, and
whether activated impersonal orientation would lead to the greatest defense and worst performance. Study 1 showed that autonomy-primed
participants report lower desire for escape compared to control-primed, and that impersonally-primed showed most desire to
escape. In Study 2, autonomy-primed participants showed the least self-serving bias, control-primed were in the middle, and
impersonally-primed participants showed the most. In Study 3, rowers autonomy-primed showed the least self-handicapping and
best performance, control-primed showed moderate levels, and impersonally-primed showed the most self-handicapping and worst
performance. Results are discussed in terms of motivation orientation, defensiveness, and performance.

Effects of guided notes versus completed notes during lectures on college students' quiz performance
We compared the effects of guided lecture notes versus completed lecture notes on pre- to postlecture improvements in quiz performance across two sections of a college course. The results of a counterbalanced multielement design did not reveal consistent differences between the two note formats on students' mean quiz scores. However, fewer errors occurred on complex (analysis-level) quiz questions in the guided notes condition than in the completed notes condition. 相似文献

"Chasing ones losses" is a key symptom among pathological gamblers (PGs). This study focuses on quantitative differences in episodic chasing (i.e., sequences of disadvantageous decisions within a single gambling session) between PGs and non-pathological gamblers (NPGs). We compared 61 PGs and 39 NPGs on the Iowa Gambling Task (IGT) and the Zuckerman Sensation Seeking Scale (SSS). The PGs showed significantly more chasing and had significantly poorer decision-making strategies than NPGs, particularly among males (F = 4.52, p < 0.05). Random players were significantly less sensation seeking than advantageous and disadvantageous (i.e., chasing) players, but there was no interaction with group or gender. The results suggest that quantifiable within-session gambling behavior holds important implications for detecting underlying vulnerabilities to gambling pathology. 相似文献

Retention management, i.e., keeping qualified employees, is a top priority for contemporary organizations. Commitment, and especially team commitment, can be the key to mastering this challenge. There is a lack of longitudinal research concerning the development and the direction of the effects of team commitment over time. In a longitudinal field-study design with three points of measurement, a total of 360 employees in 52 semi-autonomous industrial teams were surveyed over a period of three years. On the one hand, organizational commitment showed stronger effects on organization-related criteria (job satisfaction and intention to leave). These effects were consistent over the three points of measurement. Team commitment, on the other hand, affected team-related criteria (team performance and altruism). Longitudinal analyses confirmed the effects of organizational commitment on job satisfaction and intention to leave, and of team commitment on team performance and altruism. Moreover, these effects increased over time. Theoretical and practical implications of these findings are discussed. 相似文献

生涯适应力的作用:个体与组织层的跨层面分析* 总被引:1,自引:0,他引:1
生涯适应力(career adaptability)是生涯建构理论提出的自我职业生涯管理的核心概念,但国外理论和实践一直认为生涯适应力是一把双刃剑(生涯适应力高的员工工作绩效高,但其离职意向也高),本研究将对此进行检验;同时,生涯适应力作为个体职业生涯开发的核心变量,它在组织职业生涯管理跨层面作用中的价值也未曾研究。通过员工在两个时间点自评和管理者他评问卷,获得54家单位的485份有效调查问卷。结构方程模型分析的结果表明,生涯适应力不仅与工作绩效有显著正相关,而且也与离职意向有显著负相关。层次回归分析结果表明,工龄是生涯适应力与离职意向、工作绩效关系的调节变量;也就是说,工龄短员工的生涯适应力与工作绩效呈显著正相关,与离职意向呈显著负相关,但工龄长员工的生涯适应力与二者的关系都不显著。基于跨层面研究设计,多层线性模型(HLM)分析的结果表明,生涯适应力是组织职业生涯管理与个体工作绩效之间的完全中介变量,但在组织职业生涯管理与离职意向之间的中介作用不显著。这不但回答了生涯适应力对组织价值的管理困境问题,也解决了组织职业生涯管理与个体工作绩效的连接纽带问题。 相似文献
