Work schedule flexibility and family life

This paper explores the implications of work schedule flexibility for family life. Based on data from the 1977 Quality of Employment Survey, it demonstrates that flexibility of work schedules moderates the effects of nonstandard work schedules on family life. That is, nonstandard work schedules tend to have a less negative association with the quality of family life when accompanied by a high level of schedule flexibility. The paper further demonstrates that this tendency of flexibility to act as a buffer against the negative effects of nonstandard work schedules on family life is more pronounced among working women than working men.

Changes in production concepts emphasize problems in work-related well-being

Recurrent changes in work life, although necessary for competitive and financial reasons, seem to increase time pressure, stress, health complaints and safety problems of workers. The dynamics of recent workplace transformations are not sufficiently understood from the perspective of everyday work, particularly by health and safety experts. In this paper, the Activity Theoretical Approach is used to reconceptualize work-related well-being in situations of rapid change. The key concepts in this paper are production and service concepts and their asynchronies. Many asynchronies were observed in the analysis of the two cases of different types of organizations. These asynchronies are a major challenge for experts on well-being, especially since continuous change has now become an inseparable part of work life.     

基于生命经济价值理论的生产安全分析

随着经济的发展，我国生产安全问题越来越受到人们的重视。本文从生命经济价值理论出发，分析了当前我国生产安全事故多发的内在原因并提出了相应的政策建议。生命是有经济价值的，同时生命的经济价值是可以衡量的。我国现在的生产安全水平较低的主要原因是工人的生命价值较低而且发展不平衡。由于企业对伤亡员工的生命经济价值的补偿占企业因生产安全事故产生的经济损失的主要部分，员工生命价值的提高会促使企业增加对预防安全事故的经济投入，从而提高企业的安全生产水平。

Life cycle optimisation (LCO) of product systems with consideration of occupational fatalities

With the increasing pressures imposed upon industries on the environmental impacts of the manufacturing industry and chemical processes, numerous methodologies have been developed for the quantification, assessment and minimisation of waste and emissions. Meanwhile, methods for the simultaneous maximisation of economic performance within a product life cycle have also been developed. Similarly, various methodologies for screening of process alternatives based on the above factors have also been developed. However, the human lives put at risk in a supply chain constituting a life cycle tend to be overlooked as a factor of assessment, selection and optimisation of the process. Despite having life cycle assessment (LCA) methodologies for environmental assessment, no methodology has been developed for the minimisation of work-related casualties due to the unpredictable nature of workplace accidents. To address this problem, this paper develops a multi-objective optimisation model that utilises realistic statistical data for estimating the best possible pathway. The model results in the least potential fatality directly involved within the product life cycle while simultaneously minimising operating costs throughout the entire life cycle. A case study involving the utilisation of palm-based biomass formed for the production of value-added green products in Malaysia is used to demonstrate the model.

Life extension reliability analysis of decommissioned transportable seamless steel gas cylinders: A case study

Life extension reliability analysis process of decommissioned transportable seamless steel gas cylinders is proposed based on reliability index and applied to a case study in this paper. The index was calculated in terms of material stress, material strength and their probabilistic distributions. Stresses were determined by membrane equations for cylindrical shell and finite element analysis for neck, shoulder and bottom. Yield strength was measured and chosen as material strength. Probabilistic distributions were determined by distribution of material hardness. Decommissioned gas cylinders, which corrode relatively more seriously than others, could be used in the analysis for conservatively determining life extension reliability. In addition, service life of gas cylinders could be extended on condition that their reliability was more than 0.99999. Finally, the proposed analysis process was applied to determine whether some decommissioned transportable seamless steel oxygen cylinders which were manufactured in 1970s could be life extended and shown to be effective.
