Within contemporary developmental science, models derived from relational developmental systems metatheory emphasize that the basic process involved in the ontogeny of civic engagement involves mutually-influential and beneficial relations between the developing individual and his or her complex and changing social, cultural, and physical contexts (represented as individual ← → context relations). The authors suggest that research on the development of civic engagement should be theoretically predicated, use change-sensitive, longitudinal methods, and be comparative across time and place. Using these facets of scholarship as a lens, we discuss the contributions to this special issue. We conclude that the present set of studies provides a useful basis for future research and applications aimed at understanding and promoting individuals’ civic contributions, and their support of social organizations promoting individual thriving and freedom, liberty, and social justice.  相似文献

We examine socioanalytic theory from a leadership perspective and extend this research to examine the mediating mechanisms through which leader getting ahead motive and social competence influence leader effectiveness outcomes. A first-stage moderated mediation model was tested and supported, positioning the Leader Motive to Get Ahead × Political Skill interaction as influencing perceived institutional effectiveness and follower satisfaction with one’s leader through leader initiating structure behavior. This research both supports the relevance of socioanalytic theory for predicting leadership outcomes and extends socioanalytic theory to examine a mediating mechanism through which the interaction of the leader getting ahead motive and social competencies affects relevant performance outcomes. Contributions, strengths and limitations, directions for future research, and practical implications are discussed.  相似文献

Cognitive enhancing substances such as amphetamine and modafinil have become popular in recent years to improve acute cognitive performance particularly in environments in which enhanced cognition or intelligence is required. Nutraceutical nootropics, which are natural substances that have the ability to bring about acute or chronic changes in cognition have also been gaining popularity in a range of settings and applications including the workplace, driving and in the amelioration of age related cognitive decline. Huperzine A, Vinpocetine, Acetyl-l-carnitine, Rhodiola Rosea and Alpha-lipoic Acid are popular nutritional supplements that have shown promising benefits in improving a range of biological (e.g., blood flow, anti-inflammatory, anti-oxidant, and direct neurotransmitter effects) and cognitive processes from in vitro, animal and human clinical research. We report here the first human randomized clinical trial for cognition in which we administer a combination of Huperzine A, Vinpocetine, Acetyl-l-carnitine, R. Rosea and Alpha-lipoic acid (called Ceretrophin) vs placebo. Sixty participants (40 females and 20 males, with a mean age of 45.4 years, SD = 12.6) completed either the odd or even items from the Raven Advanced Progressive Matrices (APM) at baseline and the opposite odd or even items at week 4 after consuming either the combination nootropic or placebo. A significant study visit (time) × treatment condition interaction was found: F (1, 57) = 7.279, p = 0.009, partial η2 = .113, with paired samples t-tests revealing a significant improvement in mean APM score from baseline to retest (week 4) (t(34) = ? 4.045, p < .001) for the Ceretrophin? group. Improvements in APM scores could be attributed to the active intervention over the placebo, indicating that the treatment improved general intelligence. Implications for improving our understanding of the biological basis of intelligence and pharmacologically improving human cognition are discussed.  相似文献

Political skill is the capacity to understand others in working life effectively, and to apply such knowledge to induce others to act in ways that add to one's personal or organizational goals. The present investigation reported the results of 2 studies designed to examine the job performance prediction effectiveness of political skill when investigated in conjunction with general mental ability (GMA) and personality characteristics. The results demonstrated that political skill accounted for a significant proportion of job performance variance beyond GMA and personality variables cross‐sectionally in Study 1, and predictively (i.e., using a 1‐year timeframe) in Study 2 examining effects on multiple dimensions of job performance. The implications of these results, strengths, limitations, and directions for future research are discussed.  相似文献

We integrate and extend past work on self-determination theory and mixed relationships, or relationships characterized by both conflict and support, to address the question of how abusive supervision promotes subordinate organizational deviance. In so doing, we propose a mediated moderation model wherein abusive supervision and leader–member exchange interact to predict organizational deviance, with psychological need satisfaction mediating the effect of the interaction on organizational deviance. This hypothesized model was supported with multi-wave data collected from 260 employees. Notably, our model was supported after controlling for justice perceptions and organizational social exchange as alternative mediators. Theoretical and practical implications are discussed.  相似文献

Integrating Social/Political Influence Theory with the Theory of Planned Behavior, we argue that personal resources (i.e., political skill, self-efficacy) enable political candidates to form more ambitious campaign intentions, and thus perform better in elections. We tested this model with a sample of political candidates (N = 225) campaigning in a British general election. Three months before polling day, candidates provided self-ratings of political skill, domain-specific self-efficacy (i.e., campaign efficacy), and personal campaign intentions during the campaign period. Our results demonstrated that political skill was positively related to campaign efficacy, and intentions, via campaign efficacy. We also found a significant indirect effect for political skill on electoral performance (i.e., percentage of the vote), through campaign efficacy and intentions. Implications of our results for understanding candidate effects in campaigns and future research are discussed.  相似文献
