Numerous studies have recognised the importance of transformational leadership style for encouraging employees’ creativity. Self‐regulation studies have highlighted the influence of a promotion focus on employees’ creative behaviours. Yet both leadership and self‐regulation theories have paid less attention to the role transactional leadership style and situational prevention regulatory focus may play in affecting employees’ creativity. In this article we present a theoretical model which examines transformational and transactional leadership styles and both promotion and prevention situational self‐regulatory focus (SRF). The model suggests that while transformational leadership promotes creativity, at least partially by enhancing follower's situational promotion SRF, transactional leadership style (transactional active) is aligned with followers’ prevention situational SRF, which is associated with leaders’ hindering of followers’ creativity. Findings from two studies, an experimental study (N = 189) and a field study (N = 343 employees and 75 managers), support this model, showing that the relationship between different types of leadership and creativity are more complex than previously regarded. The theoretical and practical implications are discussed.  相似文献

Despite a large and growing literature on workplace discrimination, there has been a myopic focus on the direct relationships between discrimination and a common set of outcomes. The aim of this meta‐analytic review was both to challenge and advance current understanding of workplace discrimination and its associations with outcomes by identifying the pathways through which discrimination affects outcomes, examining boundary conditions to explain when discrimination is most harmful for employees, and exploring a potential third variable explanation for discrimination–outcome relationships. Mediation tests indicated that workplace discrimination is associated with employee outcomes through both job stress and justice. Moderator analyses showed that discrimination appears to be most detrimental when it is observed rather than personally experienced, interpersonal rather than formal, and measured broadly rather than specifically. We also found that discrimination–outcome relationships differ across work and nonwork contexts and as a function of the social identity targeted by discrimination. Discrimination generally explained meaningful incremental variance in outcomes after controlling for the effects of negative affectivity, but the relationships between discrimination and health were substantially decreased. We conclude by offering a constructive critique of the empirical discrimination literature and by detailing an agenda for future research.  相似文献

To evaluate the effectiveness of mindfulness-based structured versus unstructured coloring on test anxiety, 52 participants (53.8% female; Mage = 10.92 years, SD =.82) were randomly assigned to either a structured mandala (n = 26) or free coloring condition (n = 26), and completed a standardized anxiety measure to assess anxiety before and after coloring, immediately before a spelling test. Results revealed an overall decrease in anxiety for both groups. However, a significant gender by group interaction demonstrated that while both genders experienced anxiety reduction in the mandala condition, males reported a greater anxiety reduction in the free coloring condition while females only benefited from the mandala condition. Possible explanations for these gender effects are explored and future directions discussed.  相似文献

This study explored differences between homeless male veterans in metropolitan and micropolitan cities in Nebraska on sociodemographic, housing, clinical, and psychosocial characteristics as well as health service use. A convenience sample of 151 homeless male veterans (112 metropolitan, 39 micropolitan) were recruited from Veterans Affairs facilities and area shelters in Omaha, Lincoln, Grand Island, and Hastings in Nebraska. Research staff conducted structured interviews with homeless veterans. Results showed that compared to homeless veterans in metropolitans, those in micropolitans were more likely to be White, unmarried, living in transitional settings, and were far more transient but reported greater social support and housing satisfaction. Veterans in micropolitans also reported more medical problems, diagnoses of anxiety and personality disorders, and unexpectedly, were more likely to report using various health services and less travel time for services. Together, these findings suggest access to homeless and health services for veterans in micropolitan areas may be facilitated through Veterans Affairs facilities and community providers that work in close proximity to one another. Many homeless veterans in these areas are transient, making them a difficult population to study and serve. Innovative ways to provide outreach to homeless veterans in micropolitan and more rural areas are needed.  相似文献

When five theological schools realized (a) their graduates affirmed vocation as central to their theology and practice, yet (b) the parishioners of their graduates nevertheless did not feel called, they knew they had to do something. For six years, faculty teams from these schools conducted a variety of experiments in pedagogy, curriculum reform, and program development in order to train their graduates to equip all of God's people to claim and live their vocational identity in the world. This article introduces the identified challenge and necessary theological and pedagogical shift and then describes five of those experiments in greater detail.  相似文献

The present study is the first systematic investigation of computational estimation skills of multi-digit multiplication problems using an estimation comparison task. In two experiments, participants judged whether an estimated answer to a multi-digit multiplication problem was larger or smaller than a given reference number. Performance was superior in terms of speed and accuracy for smaller problem sizes, for trials in which the reference numbers were smaller vs. larger than the exact answers (consistent with the size effect) and for trials in which the reference numbers were numerically far compared to close to the exact answers (consistent with the distance effect). Strategy analysis showed that two main strategies were used to solve this task—approximate calculation and sense of magnitude. Most participants reported using the two strategies. Strategy choice was influenced by the distance between the reference number and exact answer, and by the interaction of problem size and reference number size. Theoretical implications as to the nature of numerical representations in the ANS (approximate number system) and to the estimation processes are suggested.  相似文献
