The buffering effects of supervisor support on the stressor–strain relationship have proven elusive in prior research (Beehr, Farmer, Glazer, Gudanowski and Nair (2003), ‘The Enigma of Social Support and Occupational Stress: Source Congruence and Gender Role Effects,’ Journal of Occupational and Health Psychology, 8, 220–231). We built on emerging work on source congruence and conservation of resource theory to test a series of hypotheses intended to clarify these mixed findings. Using a sample of 768 employees from 45 organizations in North America, results from moderated regression analyses, showed that the effects of supervisor support on the stressor–strain relationship depended on source congruence. In accordance with our predictions, although we found buffering effects for the physical stressors–strain relationship, we found a reverse buffering effect for the role conflict–strain relationship. These differential buffering effects did not emerge when considering coworker support. We discuss the implications of our results for shedding light on the mixed evidence regarding buffering work stressors reported in prior research. 相似文献

企业管理者工作压力的绩效属性——基于自我效能感的解释 总被引:1,自引:0,他引:1
工作压力是一个具有复杂构成特征的过程性框架概念.在明确压力结构要素的基础上,管理者的工作压力可进一步界分为内源压力和外源压力两类.文章通过相关分析发现,对于工作绩效效标而言,管理者内源、外源压力分别呈现良、劣压力属性;而基于回归分析的中介效应检验则表明,管理者的自我效能感在压力和绩效间起中介作用,这部分解释了压力绩效属性的成因和过程机制.文章的研究结论对企业开展管理者的压力管理工作具有重要的启示. 相似文献

采用TAW-2000D微机控制电液伺服岩石三轴试验机和SDAES型数字声发射仪组成的动态测试系统,对云南大红山铜矿白云岩进行了单轴压缩条件下的声发射试验,研究岩石在峰值应力前后声发射特性。试验结果表明:加载早期就有声发射活动,岩样在试验接近峰值强度时单位时间内的应力增长速度减小、声发射事件率出现明显下降,即出现相对平静期,峰值强度后的声发射现象仍然明显。 相似文献

Drawing on the attraction–selection–attrition (ASA) framework, this paper examines a mechanism, namely person–organization (P–O) fit, through which high-performance HR practices (HPHRPs) affect two negative employee outcomes: work-related stress and quit intentions. Using a sample of Egyptian public health sector workers, a mediation model is tested empirically using structural equation modelling. The study results show that HPHRPs positively affected P–O fit, which in turn had significant negative associations with work stress and quit intentions. P–O fit also explained a high proportion of mediation in the relationship between HPHRP and both outcomes. 相似文献

The human resource management (HRM) literature supports the idea that coherent systems of HRM practices can induce attitudinal effects when perceived subjectively by employees. Recently, scholars have proposed that subdimensions of HRM systems exist and account for variance in outcomes. This study explores differential effects of three subdimensions of HRM systems (skill‐, motivation‐, and opportunity‐enhancing HRM practices) on employee innovative behaviours and well‐being. Our predictions are based on the mutual gains perspective, which specifies positive relationships between HRM practices and employee performance, and the conflicting outcomes perspective that links HRM practices to higher job demands and stress. Using data from the Finnish 2012 Practices of Working Life Survey, we find support for both the mutual gains and conflicting outcomes perspectives; however, we also show that the effects of the subsets of HRM practices are heterogeneous. 相似文献

AbstractThis study investigates whether work opportunities have an impact on stress and the related turnover intentions of employees working in intergovernmental international organizations (IOs). It contextualizes the job resources and demands model within IOs’ specific work conditions. The empirical test is based on original data from a survey administered in four major organizations of the United Nations system. Results demonstrate that social work opportunities and work–life balance are organizational levers reducing stress and willingness to quit for employees who are facing red tape or the stresses of being an expatriate. In this context, the relationships between these work opportunities and turnover intention are partially mediated by stress. Contextualized HR management propositions are made to help organizations coping with these management challenges. 相似文献
