中国“入世”后 ,其劳动标准问题与其他经济和社会领域中的问题一样 ,不可避免地越来越带有国际化的色彩。究竟我国的劳动标准处于何种水平 ?是低 ,是高 ?这需要针对劳动标准的各方面内容进行一系列的比较研究。我国女职工劳动保护标准作为劳动标准体系中的一个组成部分 ,一直是国际社会关注的热点问题之一。通过比较 ,可以认为 :就水平而言 ,我国法定的女工保护标准或者与国际标准类似 ,或者高于国际标准 ;就结构而言 ,二者的框架也大体相同。但鉴于国际劳工标准的发展趋势 ,我国女工保护标准也应考虑增加某些注重促进女工社会平等方面的内容 ,如家庭责任问题等。  相似文献

Carlisle in northwest England suffered its worse floods for more than 180 years in 2005. A study, reported here, was undertaken to assess the health and social impacts of these floods via in‐depth, taped individual and focus‐group interviews with people whose homes had been flooded and with agency workers who helped them. Respondents spoke of physical health ailments, psychological stress, water health‐and‐safety issues related to the floods, and disputes with insurance and construction companies, which they felt had caused and exacerbated psychological health problems. Support workers also suffered from psychological stress. Furthermore, it was found that people had low expectations of a flood and were not prepared. The findings are presented in five sections covering flood risk awareness, water contamination issues, physical health, mental health, and impact on frontline support workers. The discussion focuses on the implications of the findings for policy and practice vis‐à‐vis psychological health provision, contamination issues, training and support for frontline support workers, matters relating to restoration, and preparation for flooding.  相似文献

This paper examines the relationship between psychological contract breach and insomnia among older workers (aged 40 years and up). Drawing upon the conservation of resources theory, we conceptualize breach as a stressful event characterized by a perceived threat, failure to gain, or actual loss of valued resources, which increases psychological distress and insomnia. Moreover, we hypothesized that older workers' generativity concerns would act as a personal resource that would buffer the negative impact of breach. We tested our proposed model in 2 studies (Study 1 = 123; Study 2 = 168) of employee–spouse dyads. Results revealed that psychological distress mediated the relationship between psychological contract breach and insomnia. These mediated relationships were significant for those with low, but not for those with high levels of generativity concerns. These effects remained significant even after controlling for perceived organizational support (i.e., a social exchange mechanism). Theoretical and practical implications are discussed.  相似文献

Objective. The provision of appropriate personal cooling vests is recognized as an effective measure to combat heat stress. However, personal cooling vests are not widely implemented in the Hong Kong industries. The current study aims to evaluate the usability of a hybrid cooling vest that is associated with the success of its application in industrial settings. Methods. A self-administrated questionnaire focusing on 10 subjective attributes of cooling effect, ergonomic design and usability of a hybrid cooling vest was administered with 232 occupational workers in the construction, horticultural and cleaning, airport apron services and kitchen and catering industries. Results. A structural equation model estimated by analysis of moment structures was constructed to evaluate the usability of the cooling vest, as influenced by cooling effect and ergonomic design. Results showed that cooling effect (path coefficient?=?0.69, p?p?Conclusions. The structural equation model is feasible to examine the complex nature of the structural relationships among the subjective perceptions of personal cooling vests. The empirical findings furnish sound evidence for further optimization of the hybrid cooling vest in terms of cooling effect and ergonomic design for occupational workers.  相似文献

Old-age pension, a fundamental part of the Chinese social security system, is perceived by the Chinese government as the last support for rural-to-urban migrant workers upon retreating from the labor market. Using survey data collected by the authors, this paper examines a host of factors which influence migrant workers’ participation in the old-age scheme. The result shows that individual characteristics, employment status, attitudes toward old-age support and perception of the old-age pension system significantly differentiate two groups of migrant workers between those that have participated in and their counterparts who have not participated in the old-age pension schemes. Among a number of factors, age, educational attainment, holding labor contract, etc. are found to be significant factors influencing migrants’ behavior participating (or not participating) the available age-pension schemes. Policy implications for how to improve the rate of participation in existing old-age pension schemes among migrant workers are drawn from the findings.  相似文献

煤矿特种作业人员岗位安全胜任力模型研究   总被引:5,自引:2,他引:3  
针对某些矿工个人具有事故倾向性现象,提出建立矿工安全胜任力模型,以加强矿工安全管理.笔者首先在对矿难人因事故报告材料分析基础上,从中发现特种作业人员应该具备的关键行为和素质,同时通过对煤矿企业特种作业人员访谈,最终设计煤矿特种作业人员岗位安全胜任力调查问卷,通过初试后的问卷项目内容分析、项目关键程度分析、探索性因子分析,形成特种作业人员岗位安全胜任力正式调查问卷.由正武调查获取数据,通过信效度分析,获得使煤矿特种作业人员表现出高安全绩效的关键素质和行为特征,构建煤矿特种作业人员岗位安全胜任力模型,安全胜任力包括安全责任意识、应急处理能力、隐患识别能力和自制力.  相似文献
