工作内容激励的条件与实施途径

工作内容激励是指工作本身对员工工作的推进作用。工作内容激励来源于工作符合员工的兴趣爱好、工作内容丰富、工作富有挑战性、工作富有成就感、工作内容兼顾员工职业发展。实施工作内容激励是项创造性的工程,此前必须以员工为中心进行工作再设计、运用"人—职匹配"理论指导工作任务的分配、创新组织形式,使之更加吻合工作内容。     

工作评价中的若干问题及其解决方法

工作评价在应用过程中存在一些可信度的疑问 ,美国科学院对工作评价方法调查的报告可以证实工作评价的方法在薪酬制度的管理中是切实可行的 ,但需要按照实际情况予以调整。建议各组织在进行薪酬结构设计和调整时考虑使用系统的工作评价方法 ,以核定不同岗位的工作价值 ;在组织的不同职位系列间尽量采用同一工作评价体系 ;对参与评价的员工进行培训。     

INDEPENDENCE DISTRIBUTION-PRESERVING NONNEGATIVE-DEFINITE COVARIANCE STRUCTURES FOR THE SAMPLE VARIANCE

This paper explicitly characterizes the general nonnegative-definite covariance structure for a multivariate normal random vector such that the univariate sample variance is distributed exactly as if the sample observations are normal independent and identically distributed (i.i.d.). This work extends the results of Baldessari (1965) and Stadje (1984) who have characterized the general positive-definite covariance matrix such that the univariate sample variance is distributed exactly as if the sample observations are normal i.i.d.     

基层公务员角色压力与工作倦怠的心理健康调节作用

为了解基层公务员角色压力、工作倦怠与心理健康之间的关系,本研究从山西、湖北、黑龙江、山东、内蒙古5省(自治区)选取在职在岗基层公务员作为调查对象,采用问卷调查法获得有效数据490份。研究发现,基层公务员角色压力中角色模糊和角色超载两个维度对其工作倦怠中的情感耗竭、人格解体和成就感低落三个维度均表现出显著的正向预测作用;心理健康在基层公务员角色压力对工作倦怠的影响关系中具有显著的调节作用,心理健康状况的提升使得角色超载对人格解体的影响有所减弱,而角色冲突对成就感低落的反向预测作用仅在心理健康水平较低的情况下表现显著。     

面向绿色制造的柔性作业车间调度优化

针对面向绿色制造的柔性作业车间调度问题,建立了以完工时间最优、能量消耗和环境影响最小为目标的调度模型,并采用遗传算法对模型进行求解。根据模型特点,采用机器染色体和工序染色体两种编码,并对初始种群的形成机制进行改进,采用精英策略和锦标赛法进行种群选择,两种染色体分别进行交叉和变异操作。最后通过实例对改进的遗传算法进行测试,并与其他方法的测试结果进行比较,验证了该算法的可行性和有效性。     

‘Quality’ part-time work in Australian organizations: implications for HRD

Part-time work is an international phenomenon. Many western countries show similar patterns to Australia, with a significant increase in part-time work in the last twenty to twenty-five years. In Australia, part-time work has developed some unique features, particularly as it often involves lower wages and poor conditions. Part-time employees in Australia are often excluded from human resource development (HRD) activities such as training and career tracks provided to full-time workers. The experience of particular Australian organizations illustrates possible avenues for quality part-time work. This paper examines practical examples of quality part-time work in eight Australian organizations across five industries (nursing, hospitality, retail, local government and the legal profession). Using case study research, the paper discusses the dimensions of quality part-time work in different industry and occupational contexts from an HRD perspective.     

An investigation of career development programs,job satisfaction,professional development and productivity: the case of Taiwan

This study attempts to develop career development programs capable of responding to career needs at different career stages. The current implementation status of these career development programs in Taiwanese businesses is then examined, along with the level of satisfaction of R&D personnel with available career development programs. The relationship between the career development programs and job satisfaction, professional development and productivity is then examined, revealing an association between high satisfaction of R&D personnel with career development programs and high job satisfaction, professional development and productivity.

基于分散网络化生产系统，针对我国中小型机械制造企业技术现状，提出了在基本上不改变现有车间基础设施的前提下，通过信息集成建立产品数据，财务和计算机辅助车间调度等管理子系统，以增强企业适应产品市场多变的能力；采用多品种，小批量生产方式，以满足产品生命周期缩短和２１世纪国际化大市场竞争的需求。     

农民工工伤保险供给与需求相关实证研究

本文以工伤事故典型病案"矽肺病"为对象,对湖南某私营煤矿农民工工伤保险参保情况进行实例调查。通过对企业工伤风险自留与保险风险转移经营成本的比较,对农民工工伤经济损失与参加工伤保险或企业私自理赔的保障水平比较,从两个角度解析了农民工工伤保险供需失衡的现状。文章认为有必要实施强制性参保,运用激励措施来提高企业参保率,有必要引入适当费率机制以缩小农民工工伤保险基金缺口。
