This article examines associations between home care workers' health, and non-standard hours and insecurity. Health refers to symptoms of stress and musculoskeletal disorders (MSDs), non-standard hours refer to part-time and casual hours, and insecurity refers to job and employability insecurity. Data come from our 2002 survey of 532 home care workers (nurses, therapists and personal support workers) in a medium-sized city in Ontario, Canada. Path analysis regression results for the conceptual model show that (1) part-time and casual hours and job insecurity are positively and significantly associated with symptoms of stress, (2) the associations between part-time and casual hours and MSDs are mediated by symptoms of stress, and (3) job and employability insecurity are directly associated with MSDs. Results provide evidence that non-standard hours and insecurity must be addressed in order to improve home care workers' health. We show the detrimental effects of non-standard hours and insecurity on workers' health, and the results have implications for employers, human resource managers, trade unionists and government policy-makers. 相似文献

During the past two decades the chain of three links organizational strategy – human resources practices – organizational performance has been deeply analysed. However, the mediator role of organizational structure in the first link of this chain remains relatively uninvestigated. In this article we analyse a model of relationships among organizational strategy, organizational structure, human resources practices, and organizational performance. Through a structural equation methodology applied to a sample of 183 Spanish companies, we will try to confirm that organizations with differentiation strategies are more likely to implement high involvement work practices. As a novelty we will introduce organizational structure as a mediator of this relationship. For that we will use the construct control mechanisms (centralization, formalization and socialization). Further, we will analyse the effect on firm performance of these proposed relationships among differentiation strategy, control mechanisms and high involvement work practices. 相似文献

The complex and changing environment of the hospitality industry presents a never ending array of stimuli, pressures and demands which can become sources of stress for hotel supervisors. A focus on the identification of current and potential stressors in organizations, and the development of strategies which individuals and management may use to manage and reduce stress effectively, is imperative. This study is to investigate the perceived level of stress of hotel supervisors, to establish frequency of the use of various coping strategies, and to determine the burnout rate. This study also empirically examines the relationships among stress, coping strategies, and job burnout. A convenient sample of hotel supervisors of large hotels in Taiwan was selected. The return of 298 questionnaires represented 74.5% of the total supervisors surveyed. The study findings suggest that the major job stress of hotel supervisors originates from task characteristic and workload. Moreover, a direct action coping strategy may allow one to perceive the situations as opportunities and may, in turn, contribute to reduce job stress. Furthermore, hotel supervisors experience a lower level of burnout if they apply more direct action strategies in coping with the pressures of their job. The results of this study can be used as part of guidelines including what should be considered to reduce job stress and burnout in the work environment. 相似文献

Dealing effectively with risks in complex projects is difficult and requires management interventions that go beyond simple analytical approaches. This is one finding of a major field study into risk management practices and business processes of 35 major product developments in 17 high‐technology companies. Almost one‐half of the contingencies that occur are not being detected before they impact project performance. Yet, the risk‐impact model presented in this article shows that risk does not affect all projects equally but depends on the effectiveness of collective managerial actions dealing with specific contingencies. The results of this study discuss why some organizations are more successful in detecting risks early in the project life cycle, and in decoupling risk factors from work processes before they impact project performance. The field data suggest that effective project risk management involves an intricately linked set of variables, related to work process, organizational environment, and people. Some of the best success scenarios point to the critical importance of recognizing and dealing with risks early in their development. This requires broad involvement and collaboration across all segments of the project team and its environment, and sophisticated methods for assessing feasibilities and usability early and frequently during the project life cycle. Specific managerial actions, organizational conditions, and work processes are suggested for fostering a project environment most conducive to effective cross‐functional communication and collaboration among all stakeholders, a condition important to early risk detection and effective risk management in complex project situations. 相似文献

基于2008-2018年贵州省9个地级市和自治州的面板数据,实证检验高铁开通对区域要素禀赋与经济增长的影响。结果表明:高铁开通在总体上促进了贵州省区域经济增长,提高了劳动力要素的相对丰裕程度。然而,高铁开通并未表现出技术溢出作用,反而降低了劳动力和资本要素的边际生产率,对要素禀赋结构优化和区域经济长期发展产生不利影响。基于此提出,应因地制宜科学规划高铁建设,推进科学技术创新,加强高素质人才培养与引进,优化营商环境,提升社会保障水平,以发挥高铁的扩散效应,降低聚集效应,进而改善要素禀赋结构,促进区域经济协调发展。 相似文献

锅炉理论上对风量的需求与实际并不相符,实际风量需求处于不断的变化过程中,其变化的主要标准为负荷。为了能够对锅炉在不同时段与不同状态中对风量的不同需求进行满足,要实现高压变频技术在风机中的应用。本文首先对高压变频器的基本原理与风机的变频节能原理进行了分析,通过对风机的变频改造工作,实现了风机变频调节节能效果的提升。通过高压变频技术实现风机节能改造之后,其节电率得到了明显的提高,节能效果非常的显著,为风机的变频改造提供了参考与借鉴。 相似文献
