Recruitment and retention of nurses is a major concern in healthcare provision in several countries. This study explored the relationship between perceived social support, job stress, health, and job satisfaction among nurses from 4 organizations in northwest England. A total of 350 usable questionnaires measuring stressors, perceived support, health, and job satisfaction, was obtained from a sample of 1,162 nurses drawn from 4 healthcare organizations. A follow-up study was conducted after 6 months. Results indicate that perceived organizational support is related to nurses' health and job satisfaction. Current interventions to increase support, which typically operate at individual or group level, may be limited in their effectiveness unless nurses' perceptions of organizational support are taken into account.  相似文献

This study investigates the relationship between emotion, reason and perceived risk. Evidence is presented using an aggregative data set of 146 products and services which were randomly selected from the SIC (Standard Industrial Classification Codes) manual. It is demonstrated that emotional factors account for a significant and substantial portion of the variance in perceived risk even after the effect of rational factors (perceived differences between alternatives) has been taken into account. It is suggested that emotion be explicitly modelled in future conceptualisations of perceived risk. Copyright © 2002 Henry Stewart Publications.  相似文献

This study aims to investigate whether crisis support and coping mediate symptoms of posttraumatic stress disorder (PTSD) in individuals with spinal cord lesions (SCL). PTSD, crisis support, and coping were assessed an average of 83 days after the injury (T1), at discharge from the rehabilitation center (T2), and an average of 121 days following discharge (T3). Sixty-nine newly injured paraplegics and tetraplegics completed the questionnaire at T1, 40 (58%) at T2, and 38 (55%) at T3. Individuals with PTSD experienced significantly lower levels of social support, and used more emotional coping than did those without PTSD. On the basis of logistic regression analyses, emotional coping and the interaction between negative response and emotional coping predicted PTSD. Emotional coping is a strong predictor of PTSD in persons with new SCL.  相似文献

We investigated how situational (gain–loss), informational (opportunity–threat framing) and dispositional (achievement motive and avoidance motive) variables affected opportunity–threat perception and risky choice in managerial decision-making contexts. In Study 1, the risk preference of the participants showed a reflection effect due to situational differences (gain or loss) and a partial framing effect caused by presenting the same choice information in terms of either opportunities or threats. However, both effects were in the opposite direction of predictions from prospect theory. Gains and positive framing enhanced risk-seeking preference whereas losses and negative framing augmented risk-averse preference. Risk-seeking choices were mediated by opportunity perception whereas risk-averse choices were mediated by threat perception. In Study 2, the participants high in achievement motive perceived greater opportunities in a negative situation, and the participants high in avoidance motive perceived greater threats in a positive situation, suggesting that ambition (achievement motive) operates more significantly in the face of adversities whereas cautiousness (avoidance motive) functions more significantly in prosperity.  相似文献

Cheating and rule violations in intercollegiate athletics continue to be relevant issues in many institutions of higher education because they reflect upon the integrity of the institutions in which they are housed, causing concern among many faculty members, administrators, and trustees. Although a great deal of research has documented the numerous rule violations in NCAA intercollegiate athletics, much of it has failed to combine sound theory with practical solutions. The purpose of this study was to examine the possible extensions of the organizational justice framework to the problem of rule violations in intercollegiate athletics. In doing so, the current study examined (a) perceived areas of injustice among coaches at NCAA Division I institutions, (b) avenues by which coaches resolve these injustices, and (c) potential solutions for resolving injustices in an attempt to reduce NCAA violations. Six NCAA Division I basketball coaches from various parts of the country (four from men's teams and two from women's teams) were interviewed using a semi-structured format. Despite the NCAA's efforts to create parity, results showed that coaches perceived several areas of inequities in recruiting, including financial resources and academic standards. The interviewed coaches described several means that are currently used to resolve these inequities and offered recommendations for changes to reduce injustice in the future.  相似文献

本文考察了背景信息导航帮助(结构背景信息导航帮助、时间背景导航信息帮助和综合背景信息导航帮助)和认知风格(场独立倾向和场依存倾向)对超文本使用过程中导航绩效和学习效果的影响。结果表明:(1)认知风格是研究超文本系统的一个敏感指标:在超文本阅读过程中,场依存倾向的人比场独立倾向的人容易迷失,在某种程度上,学习效果要低于场独立倾向的人;(2)最优路径偏离可以敏感地反映出超文本网络空间中使用者的迷失程度;(3)主观迷失感与导航绩效相比,更能有效地预测超文本环境下的学习效果。  相似文献

Two studies examined individual and environmental forces that affect engagement in prosocial behavior. Self-determination theory was used to derive a model in which autonomy orientation and autonomy support predicted satisfaction of three core psychological needs, which in turn led to engagement in prosocial activities. In Study 1, college students reported their engagement in various prosocial activities, and completed measures of autonomy orientation, parental autonomy support, and general need satisfaction. In Study 2, volunteer workers completed measures of autonomy orientation, work autonomy support and need satisfaction at work. The number of volunteered hours indicated the amount of prosocial engagement. Results across the studies showed that autonomy orientation was strongly related to engagement in prosocial behavior, while autonomy support was modestly related. Need satisfaction partially mediated the effect of autonomy orientation, and fully mediated the effect of autonomy support. Interestingly, autonomy support predicted lower volunteer turnover. Implications for how prosocial behavior can be motivated are discussed.  相似文献

This study extended the current literature on group diversity by examining the moderating influence of perceived group openness to diversity on the relationships between perceived individual visible, informational, and value dissimilarity; individual task and relationship conflict; and work group involvement. A survey was administered to 129 public service employees who worked in intact teams. Results revealed that value dissimilarity had a positive association with task and relationship conflict and a negative association with work group involvement. Perceived group openness to diversity moderated the associations between visible and informational dissimilarity and work group involvement, and between value dissimilarity and task conflict. These results highlight the importance of managing differences by introducing norms promoting diversity and the involvement of all team members.  相似文献

Marital conflict: Correlates, structure, and context   总被引:2,自引:0,他引:2  
Marital conflict has deleterious effects on mental, physical, and family health, and three decades of research have yielded a detailed picture of the behaviors that differentiate distressed from nondistressed couples. Review of this work shows that the singular emphasis on conflict in generating marital outcomes has yielded an incomplete picture of its role in marriage. Recently, researchers have tried to paint a more textured picture of marital conflict by studying spouses' backgrounds and characteristics, investigating conflict in the contexts of support giving and affectional expression, and considering the ecological niche of couples in their broader environment.  相似文献
