工作满意度、年龄与主观幸福感——基于武汉市城镇居民的分析

本文基于2007年武汉市城镇居民的主观幸福感调查数据,首先运用层次分析法对武汉市城镇居民的工作满意度水平进行了测算,并在此基础上对工作满意度与主观幸福感之间的关系进行了研究。结果表明,工作满意度对主观幸福感具有正外溢效应。但是,如果考虑到年龄与工作满意度之间的关系,这种正外溢效应的强度将随着年龄的增加而减弱。     

企业员工核心自我评价与工作绩效的关系研究

采用核心自我评价、工作绩效问卷为研究工具,对1010名企业员工进行调查,探讨核心自我评价与工作绩效的关系。结果发现：核心自我评价与员工工作绩效存在显著正相关,且能够有效预测员工的工作绩效。核心自我评价对关系绩效的作用要大于其对任务绩效的作用。核心自我评价问卷可以作为预测企业员工工作绩效的有效测评工具。     

晶振加工过程中磨削系统优化设计

利用CAXA软件绘制晶振磨削机构简图,并使用ANSYS分析软件对现有设备的磨削机构进行ANSYS分析,对相等磨削接触力的情况下不同的磨削角度产生的最大应力做比较,在机构的运动传递中引入阻尼元件,实现刚性到柔性的转化。[HTK]分析结果表明,磨削角度的改进和阻尼元件的引入,减少了石英音叉的磨削硬性冲击,减少断片率,也简化了进给调速的控制。     

Health habits,type A behaviour and job burnout

Abstract

This study examined the effects of health habits and type A behaviour on psychological health outcomes in the face of daily life stress. Measures of the experience of life stress, health habits, type A behaviour, job burnout and psychological distress were collected for 146 employees at the UCLA Medical Centre. Analyses of covariance revealed that health habits contributed significant main effects to psychological distress but not job burnout. Type A behaviour, but not life stress or health habits, directly affected both job burnout and psychological distress. The implications of the research for employee health programmes are discussed.     

Operator performance and subjective response in control of flexible manufacturing systems

Abstract

In this study, allocation of functions and system size (number of machines) were manipulated to test their effects on operator performance and subjective response in a flexible manufacturing system (FMS). An experiment was conducted using a cross-over design with three independent variables: number of machines, task allocation, and sequence of task presentation. Operator performance was measured by response time, and subjective response assessed using two questionnaires. Physiological measures were also taken (EKG and respiratory rate). The results revealed that the number of machines in the system did not affect performance or subjective or physiological response while the effect of allocation level was significant for both performance and subjective response.     

中国铁路机车司机工作压力源结构模型研究

对中国机车司机面临的工作压力进行研究，因近年发生的多起人因恶性铁路安全事故而显得紧迫。在对上海、北京等10个铁路局问卷调查的基础上，通过SPSS和AMOS分析，最终构建的中国机车司机工作压力源结构模型包括8个因素：工作环境、工作负荷、角色冲突、组织管理、管理行为、事业发展、人际关系以及工作与家庭。     

Fight or Flight? Factors Influencing Child Welfare Workers' Propensity to Seek Positive Change or Disengage from Their Jobs

ABSTRACT

This cross-sectional study tests a theory-driven, conceptual model examining factors supporting or hindering child welfare workers' (n = 359) efforts to speak up (voice) or disengage psychologically (neglect) or physically (exit) from their jobs. Based on path analysis results, key findings indicate that workers who feel included in decision-making are more likely to exercise voice and less likely to engage in neglect. In contrast, workers who experienced supervisory and organizational support are less inclined to exit. The findings should be instructive to scholars and practitioners interested in capturing how employees' responses to stressful and complex work environments are expressed.
