AbstractPerceived work-related stress has increased notably in recent years, reducing individuals’ well-being and increasing organizations’ and economies’ costs. This study focuses on worktime control as a key approach to reducing work stress, as the extant research on its effects reports inconsistent results. The study argues that comparisons play a major role in how work stress, conceptualized as effort-reward imbalance, occurs. Ordinary least squares is used to test hypotheses with a sample of 1721 employees from Germany to determine whether employees’ prior worktime control and employees’ referents’ worktime control affect the relationship between worktime control and work stress. Results show that (1) worktime control is negatively associated with the experience of work stress, (2) employees’ prior worktime control moderates the relationship between worktime control and work stress, and (3) there is no moderating effect of employees’ referents’ worktime control. The results are discussed in light of gift-exchange theory and related empirical findings. 相似文献

In this paper, we engage with the rising importance of journal ranking lists. We explore the pressure these place on marketing academics and the politics of knowledge production, stressing academic game-playing, careerism, and paradigmatic homogeneity. We appreciate that scholars are disciplined by these lists, their line managers, and reaffirm list power through their own patterns of self-management. Nonetheless, marketing academics should avoid making the naïve assumption that the appearance of a paper in a highly rated journal necessarily serves as a proxy for ‘quality’. Publication in a particular outlet does not transform the ultimate contribution being made in any substantive fashion. We provide an extensive critique of the function and impact of journal lists. However, it is also recognised that these are very important for members of the marketing community. As such, we explain our reasons for contesting the recent regrading of the Journal of Marketing Management (JMM) by a prominent journal list and underline the changes that have been made to the Journal since the beginning of the current editorial term. Finally, the support of prominent scholars among our thought community for the policies being implemented is highlighted and we underscore the rigour of contributions to the Journal, the review process, the rising citations, downloads and truly global readership of the JMM. 相似文献

This research note investigates the moderating effects of presenteeism on the stress-happiness relationship of 358 hotel employees in Sabah, Malaysia. The results support the moderating role of presenteeism in the relationship between stress and happiness. More specifically, the findings identify the presence of a non-monotonic relationship between perceived stress and happiness over the range of the degree of presenteeism. Contributions and limitations of the study are identified and discussed. 相似文献

商业银行信用风险与宏观经济——基于压力测试的研究 总被引:1,自引:0,他引:1
本文采用压力测试框架,研究了宏观经济波动对商业银行信用风险的影响。文章以不良贷款率度量信用风险,以名义GDP增长率、广义货币供应量(M2)增速、居民消费价格指数(CPI)以及房地产销售价格指数作为宏观经济变量,建立了合适的宏观压力测试模型。在GDP增速放缓、CPI上升、M2增速下降的压力情景下,预测了2011年第一季度到第四季度的不良贷款率的变化路径。实证结果表明在压力情景下商业银行的不良贷款率将会显著上升。 相似文献

Two studies investigate the immediate and long-term effects of job stressors on frontline service employees (FSEs). Using cognitive appraisal theory, we develop and test a conceptual model of two job stressors (crowding and emotional labor) that affect coping strategies and job outcomes. Study 1, which is a field experiment, investigates the immediate effects of crowding in a single firm. Study 2 extends the findings of Study 1 and investigates the long-term effects of emotional labor and crowding on FSEs across multiple firms. The results show that crowding has a negative impact on coping strategies and job-related outcomes. In addition, emotional labor can lead to long-term negative outcomes, such as emotional exhaustion and decreased job retention, for some FSEs. Consequently, service organizations should consider strategies or tactics that prevent high levels of customer crowding and help FSEs deal with emotional labor. 相似文献
