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

Our aim was to identify in the scientific field of social psychology and management, the different academic approaches and models of the proactivity concept. In the first instance, the proactivity concept is mentioned as a dispositional variable and an interindividual difference involving personality traits and associated behaviors. In the second, we more specifically explore proactive behaviors and their features. In a complementary manner, we expose some environmental elements understood to promote the initiation and continuation of proactive behavior (decision latitude, autonomy, transformational leadership). Finally, we introduce a few proactivity concept limitations and benefits of using such behaviours in organizational environment. We then conclude this work with a few research proposals such as the variability of the proactivity level and the possibility of acquiring proactive behaviours.  相似文献

Organizational measurement is necessary for managing incremental improvements or change efforts. Some have argued that indicators of financial performance measure the past and should be joined by "lead" measures such as management development and customer relations, assumed to be drivers of performance. Approaches of "lead" measures have met criticism for not contributing to operational management. The present is an empirical case study where measures from a customer satisfaction survey and a management assessment instrument were analyzed and compared to actual measures of financial performance. The effects of measures obtained seem to depend on the interpretations and reflection taking place in the organization. The pursuit of "lead" indicators did not seem to drive results. Counter-intuitively, higher scores on these measures were related to poorer financial performance. The explication of and reflection on the underlying dynamic seemed to turn the development in a profitable direction.  相似文献

Nanotechnology — A new field of ethical inquiry?   总被引:2,自引:0,他引:2  
Parallel to the public discussion on the benefits and risks of nanotechnology, a debate on the ethics of nanotechnology has begun. It has been postulated that a new “nano-ethics” is necessary. In this debate, the — positive as well as negative — visionary and speculative innovations which are brought into connection with nanotechnology stand in the foreground. In this contribution, an attempt is made to discover new ethical aspects of nanotechnology in a more systematic manner than has been the case. It turns out that there are hardly any completely new ethical aspects raised by nanotechnology. It is much rather primarily a case of gradual shifts of emphasis and of relevance in questions which, in principle, are already known and which give reason for ethical discussions on nanotechnology. In a certain manner, structurally novel ethical aspects arise through the important role played by visions in the public discourse. New questions are also posed by the fact that previously separate lines of ethical reflection converge in the field of nanotechnology. The proposal of an independent “nano-ethics”, however, seems exaggerated.  相似文献

Conventional wisdom in the diversity literature holds that job-related dimensions of diversity are the domain of positive performance, whereas demographic dimensions of diversity are the domain of negative performance effects. In a meta-analysis (N = 146 studies, 612 effect sizes), we show that this conclusion may be based on rater biases; it does not apply to studies involving more objective assessments of performance, assessments that cannot be influenced by knowledge of a team’s composition. We also show that the influence of job-related diversity is moderated by task complexity and that job-related diversity is more positively related to innovative performance than to in-role performance. We discuss how these results invite a reconsideration of the role of the job-related/demographic diversity distinction and provide suggestions on how to further advance our understanding of diversity’s effects.  相似文献

It has been suggested that effort invested in a task may be moderated by the perception of the nature of reward offered, e.g., whether social or financial in nature. If levels of payment for empirical work meaningfully influence the effort invested in tasks by participants, the implications may be serious and wide-ranging for the reliability and validity of published data. The study reported in this paper, examines this thesis in a driving context. Thirty-six participants were allocated to either a No payment, Low payment or Medium payment condition in a driving simulator. They undertook both easy and difficult driving scenarios in which performance was measured. Subjective workload and performance results indicated that task difficulty was successfully manipulated with the study. However, in contrast to the previous research in non-driving contexts, participants not receiving rewards were found to perform more poorly and experience increased time pressure.  相似文献

The present study explored the influence of dispositional perfectionism (i.e. perfectionistic concerns and perfectionistic strivings) on tension and performance under low or high experimentally induced stress. Results support the moderating role of perfectionism concerning tension and indicate that stress-related processes underlie the vulnerability of perfectionistic concerns. In addition, buffering effects of perfectionistic strivings were found, supporting the 2 × 2 model of dispositional perfectionism by Gaudreau and Thompson (2010). No evidence was found for the moderating role of perfectionistic strivings concerning performance, but results provide evidence for positive effects of perfectionistic concerns on performance.  相似文献

This study's primary goal was to evaluate the use of performance feedback procedures delivered to a classroom team to increase daily data collection. Performance feedback (PFB) was delivered to four classroom teams responsible for the daily collection of data representing student performance during prescribed instructional activities. Using a multiple-baseline design, the effects of the team performance-feedback were evaluated for the target student, and for generalization to data collection for all classroom students. A secondary question evaluated if student on-task behavior correlated with increased data collection. Finally, social validity was investigated to evaluate team satisfaction with the PFB intervention. The results demonstrate improved data collection across all four classroom teams for the target student in each classroom and generalization within classrooms to all remaining students. Slight increases in student on-task behavior were observed in three of the four classrooms, and teacher satisfaction ratings were high.  相似文献
