The influence of relational identification (RI) on leadership processes and the effects of social identity leadership on followers' responses to stress have received scant theoretical and research attention. The present research advances theoretical understanding by testing the assertion that high RI with the leader drives follower mobilization of effort and psychophysiological responses to stress. Two experimental scenario studies (Study 1 and Study 2) support the hypothesis that being led by an individual with whom followers perceive high RI increases follower intentional mobilization. Study 2 additionally showed that high (vs. low) RI increases follower resource appraisals and cognitive task performance. A laboratory experiment (Study 3) assessing cardiovascular (CV) reactivity showed that, compared to neutral (i.e., non-affiliated) leadership, being led by an individual with whom participants felt low RI elicited a maladaptive (i.e., threat) response to a pressurized task. In addition, relative to the low RI and neutral conditions, high RI with the leader did not engender greater challenge or threat reactivity. In conclusion, advancing social identity leadership and challenge and threat theory, findings suggest that leaders should be mindful of the deleterious effects (i.e., reduced mobilization and greater threat state) of low RI to optimize follower mobilization of effort and psychophysiological responses to stress. 相似文献

The proportion of young people taken into the care of the state has increased recently and there is evidence that this social group suffer negative long‐term outcomes that might be conceptualised by the emergent criminological category of ‘social harm’. Debates in social work around an ethics of care and justice offer different ways of thinking about responding to social harm. This paper reports findings from an innovative arts‐based intervention with Looked After Children and young people and concludes that holding these competing value sets in creative tension is central to the success of the programme in helping young people to cope with and contest social harm. 相似文献

Rendering sexism invisible in workplace narratives. A narrative analysis of female entrepreneurs’ stories of not being talked to by men 下载免费PDF全文
Entrepreneurism is widely regarded as being one way in which women can sidestep the sexism of male‐dominated institutionalized work environments and enter into a world in which men and women operate on a level playing field. Yet, in a corpus of stories of female entrepreneurs’ experiences, we noted that being ignored by men was a constant theme. Taking a social constructionist and narrative approach to identity, we analyse the gendered identity work that female entrepreneurs do in these stories and we seek to explicate the process through which female entrepreneurs do not evaluate being ignored by men as sexism‐in‐action. Using positioning theory as an analytical tool, we analyse these stories at three different levels: the here‐and‐now interaction between interviewer and storyteller; the there‐and‐then identity work of the characters in the storyworld; and the wider societal Discourses that the storytellers enact, and which are enacted by such identity work. Findings indicate that despite making gendered difference, inferiority and lack of agency relevant, the stories are not evaluated as sexism‐in‐action because the female entrepreneurs enact a postfeminist and neoliberal Discourse of freedom, autonomy and choice, rather than a feminist Discourse of discrimination and sexism. 相似文献

Proportional hazards are a common assumption when designing confirmatory clinical trials in oncology. This assumption not only affects the analysis part but also the sample size calculation. The presence of delayed effects causes a change in the hazard ratio while the trial is ongoing since at the beginning we do not observe any difference between treatment arms, and after some unknown time point, the differences between treatment arms will start to appear. Hence, the proportional hazards assumption no longer holds, and both sample size calculation and analysis methods to be used should be reconsidered. The weighted log‐rank test allows a weighting for early, middle, and late differences through the Fleming and Harrington class of weights and is proven to be more efficient when the proportional hazards assumption does not hold. The Fleming and Harrington class of weights, along with the estimated delay, can be incorporated into the sample size calculation in order to maintain the desired power once the treatment arm differences start to appear. In this article, we explore the impact of delayed effects in group sequential and adaptive group sequential designs and make an empirical evaluation in terms of power and type‐I error rate of the of the weighted log‐rank test in a simulated scenario with fixed values of the Fleming and Harrington class of weights. We also give some practical recommendations regarding which methodology should be used in the presence of delayed effects depending on certain characteristics of the trial. 相似文献

This article explores the ways in which students' voices can be used to analyse the process of moving schools, at a time outside of those that young people normally change schools. The paper is based on a study in a secondary school and uses qualitative data collected by researchers and student co‐researchers. Two areas were raised by students as important about being at a new school: the perceived challenges and their perceptions of learning in a new environment. It is argued that to respond to issues that arise due to mobility, an engagement with students' views is necessary. Furthermore, this can facilitate policy‐makers, school leaders and educators in providing more effective support for those young people. 相似文献

Delay discounting (DD) is a measure of impulsivity that describes the subjective decline in value of a consequence as the delay to that consequence increases. We sought to assess whether the results of a monetary DD task would be predictive of sexual risk-taking in a group of Internet-using men who have sex with men (MSM). 1402 participants completed an online survey that included questions about the participant’s demographics, sexual history and behavior, drug use, sexual compulsivity, and a monetary DD task. High DD was associated with increased odds of reporting >2 UAI partners in the past 12 months [aOR = 1.5 (1.1–2.1)]. Future studies should examine the utility of DD as a predictor of risky sexual behavior, as well as explore the possibility of HIV prevention interventions targeting DD. 相似文献

Objectives: This study examines the relationships between information motivation behavioral skills model constructs and their associations with consistent condom use and condom use problems among young Black men. Methods: The authors use baseline data collected from 702 participants in a randomized controlled trial. Analyses involved path modeling and bootstrapped standard errors to estimate associations. Results: Motivation had the largest association with consistent condom use, whereas condom application skills had the largest association with condom use problems. Conclusion: Motivation is the most important predictor of consistent condom use, whereas condom application skills are the most important predictor of condom use problems. 相似文献
