In this study, we examine the combined effect of leader trait anger and impulsiveness (narrow neuroticism sub-factors) on ethical leadership and organization member adaptivity. Data from working leaders, their followers and direct managers provide preliminary evidence that high trait anger and high impulsiveness relates to low follower-rated ethical leadership, and low manager-rated organization member adaptivity. Similarly, there was a stronger negative association between trait anger and ethical leadership for leaders with high as opposed to low impulsiveness. Implications for research and practice are discussed. 相似文献

基于人-环境匹配理论和压力认知交互作用理论, 本文探讨了下属需求和接受的授权型领导匹配性对下属态度、行为和绩效的影响及情绪耗竭的中介作用。本文分别通过对150位领导与150位下属(研究1)、50位领导与243位下属(研究2)的配对样本开展两项多时点、多来源的问卷数据收集, 并采用跨层次多项式回归和响应面分析方法得出以下结论: (1)下属需求和接受的授权型领导失配会导致下属情绪耗竭; (2)相对于授权不足, 领导的过度授权更会导致下属情绪耗竭; (3)下属需求和接受的授权型领导匹配性通过作用于下属情绪耗竭进而影响下属对领导的满意度、组织公民行为和工作绩效。 相似文献

Athlete perspectives on the enablers and barriers to nutritional adherence in high-performance sport
ObjectivesPoor adherence to nutritional guidance by athletes may compromise their health and performance. Enhancing adherence is therefore an important performance and welfare strategy. The aim of this study was to qualitatively explore the barriers and enablers of elite athletes' adherence to nutritional guidelines.DesignUnderpinned by our constructionist epistemological position and our relativist ontology, we conducted a qualitative study using focus groups.MethodsWe used the Capability, Opportunity, and Motivation Behaviour (COM-B) model and the Theoretical Domains Framework (TDF) to conduct focus group discussions with a purposive sample of 39 UK-based funded athletes (mean age = 23 ± 3.81), participating in either Olympic and Paralympic sport (n = 30) or professional sport (n = 9), who had access to a nutritionist. Data were analysed using reflexive thematic analysis.ResultsAthlete adherence to nutritional guidance was seasonal and included inadequate energy intakes and episodes of binge eating. Underpinning these behaviours, athletes' emotional barriers (motivation) are reinforced through their social interactions within the high-performance environment (opportunity) and athletes' training environment limits developmental opportunities for food planning (capability). However, a holistic-developmental approach by the sports nutritionists (opportunity) supports athlete wellbeing and nutritional adherence.ConclusionThese findings advance theoretical understanding of the barriers and enablers of nutritional adherence amongst elite-level athletes in high-performance sport and present a number of significant implications for athlete support personnel seeking to enhance performance in demanding sporting contexts. Drawing on the Behaviour Change Wheel (BCW), recommendations include the need to 1) train and educate sports nutritionists in human behaviour, 2) update regulations for sports nutrition profession practice to acknowledge the skills required to support athletes' emotional wellbeing, 3), educate coaches on the sensitivity of body weight and composition and develop guidelines for monitoring athletes' body weight and composition in sport, 4) persuade influential leaders to develop culture guidelines that shift the performance-narrative of high-performance (i.e., environmental restructuring). 相似文献

ObjectivesThe present research investigates how coaches' identity leadership predicts individual and team outcomes in soccer. Specifically, we tested hypotheses that coaches' identity leadership would be associated with players' perceptions of (a) higher team effort, (b) lower turnover intentions, (c) better individual performance, and (d) better team performance. In addition, we aimed to examine the relationship between coaches' identity leadership and increased team identification of players and the degree to which the associations of identity leadership with these various outcomes were mediated by players' strength of team identification.DesignWe conducted a cross-sectional study of male soccer players in Germany.MethodThe final sample consisted of 247 male soccer players nested in 24 teams that completed measures of their coaches' identity leadership, team identification, team effort, turnover intentions, and individual/team performance.ResultsAnalysis revealed a positive relationship between coaches' identity leadership and team effort, as well as individual and team performance. Moreover, coaches' identity leadership was associated with lower turnover intentions. There was also evidence that the relationships between identity leadership and the investigated outcomes were mediated by team identification.ConclusionsThese findings support claims that coaches' identity leadership is associated with better individual and team outcomes because it helps to build a sense of ‘we’ and ‘us’ in the team they lead. 相似文献

The social identity approach is fast becoming a prominent framework for understanding effective leadership in sport and exercise contexts. The last five years, in particular, has seen a proliferation of research informed by the identity leadership approach, with a focus on two broad outcomes: performance and health. Using these two key outcomes as an organising framework, we provide a critical narrative review of research that has examined the presence, role, and benefits of identity leadership in sport and exercise contexts, and identify fruitful avenues for future research. Applying a broader lens, we then make five key recommendations for future identity leadership research in sport and exercise contexts. Specifically, we highlight the need for research (a) using more rigorous and varied research designs, (b) using stronger measures, (c) comparing the effects of identity leadership to the effects of other types of leadership, (d) assessing further potential mediators of relationships between identity leadership and key outcomes, and (e) exploring the possible dark side of identity leadership. 相似文献

在当今知识经济时代, 新技术的采用对于企业提高核心竞争力至关重要。如何使员工面对新技术带来的风险和不确定性, 信任并接受新技术是企业新技术推广的重要问题。现今学界虽已关注到信任在新技术采用这一过程中的积极作用, 但仍缺乏相关的理论和实证研究, 特别是对于其内在心理机制的解释。为弥补这一研究的不足, 本研究通过分析企业新技术推广情境下, 技术信任和领导信任对员工新技术接受的影响, 并引入了感知风险性与技术自我效能感作为中介变量, 探寻信任影响的内在机制。此外, 还进一步探讨企业文化的调节作用, 从而建构信任与企业员工新技术接受的理论模型, 为企业新技术的推广提出合理建议。 相似文献

本研究基于内隐领导理论,运用配对问卷法,探究领导者性别身份的三种评价差异:自我评价与下属评价的差异,男性领导与女性领导的下属评价差异,男性下属与女性下属的评价差异。结果显示,与领导者自评的性别身份相比,下属易高估领导者的男性化;且下属评价男性领导的男性化显著高于女性化,而评价女性领导时两者并不存在显著差异。此外,男性下属对领导男性化的评价高于女性下属的评价。 相似文献

The effects of social isolation on aggressive behavior and rank order have been investigated in small groups of juvenile angelfish, Pterophyllum scalare. An experimental protocol including a “double transfer” of the subjects was used, in which fish were transferred to new aquaria in groups, before subsequent isolation and regrouping. A significant decrease in aggression was observed in the first recording session following both isolation and group transfer, after which the level returned to that recorded in the home tanks. The social hierarchy was also perturbed, but changes generally involed the two highest ranking fish in two out of the three groups, and were found not to be statistically significant. The behavior patterns are interpreted as adaptive responses to environmental change. © 1993 Wiley-Liss, Inc. 相似文献
