中国知识分子:短命还是长寿?--中国知识分子健康研究报告之一 总被引:8,自引:0,他引:8
本文考察了中国知识分子的平均预期寿命,挑战了广为流行的观点.本文首先解释"死亡人口平均年龄"与"平均预期寿命"指标的概念和差异;然后使用2004年在中科院18个研究所以及北京大学、清华大学共20个单位调查的死亡人口资料,检验"知识分子死亡平均年龄下降趋势"的可信性;并利用全国第四次和第五次人口普查的权威数据,计算受过本科以上教育人群的生命表和"平均预期寿命",得出中国知识分子预期寿命大大高于普通人群的结论,推翻了"中国知识分子预期寿命比全国平均寿命低17岁"这个流传广泛且被反复引用的错误结论. 相似文献

Modern point‐of‐use technology at hospitals has enabled new replenishment policies for medical supplies. One of these new policies, which we call the hybrid policy, is currently in use at a large U.S. Midwest hospital. The hybrid policy combines a low‐cost periodic replenishment epoch with a high‐cost continuous replenishment option to avoid costly stockouts. We study this new hybrid policy under deterministic and stochastic demand. We develop a parameter search engine using simulation to optimize the long‐run average cost per unit time and, via a computational study, we provide insights on the benefits (reduction in cost, inventory, and number of replenishments) that hospitals may obtain by using the hybrid policy instead of the commonly used periodic policies. We also use the optimal hybrid policy parameters from the deterministic analysis to propose approximate expressions for the stochastic hybrid policy parameters that can be easily used by hospital management. 相似文献

Abstract Numerous tools have been developed that attempt to measure work-related stress and working conditions, but few practical instruments in the literature have been found to have a reliable psychometric factor structure. In the UK, the Health and Safety Executive (HSE) Management Standards (MS) Indicator Tool is increasingly used by organizations to monitor working conditions that can lead to stress. In Health and Safety Executive (2004), a factor analysis was conducted demonstrating the reliability of the scales. However, the authors acknowledged that direct reassessment of the same factor structure was impossible as the questionnaire was split into two separate modules for data collection. Furthermore, the tool is designed to enable comparisons between as well as within organizations to take place, yet reliability has only previously been tested at the individual level. The current study is the first to examine the factor structure of the HSE MS Indicator Tool using organizational-level data. Data collected from 39 UK organizations (N=26,382) was used to perform a first-order Confirmatory Factor Analysis (CFA) on the original 35-item seven-factor measurement scale. The results showed an acceptable fit to the data for the instrument. A second-order CFA was also performed to test if the Indicator Tool contains a higher order uni-dimensional measure of work-related stress. These findings also revealed an acceptable fit to the data, suggesting that it may be possible to derive a single measure of work-related stress. Normative data comprising tables of percentiles from the organizational data are provided to enable employers to compare their organizational averages against national benchmarks. 相似文献

Abstract Analysis of the literature and examination of the various models of integration and testing in the field, have revealed five key issues relating to management system integration. This paper examines the recently published ISO 9001 : 2000 quality management system standard to see how it addresses these issues, under the headings of compatibility, scope and organizational culture. The examination reveals that while compatibility with the ISO 14001 and OHSAS 18001 standards has been improved in some areas, a different approach and model of a management system has been used. The paper suggests that differences in the scope of the standards are also likely to give rise to different sub-cultures which will hinder integration, and scope and culture are more important than compatibility. This leads the authors to conclude that new models of integration should be based on an approach and definitions which can be used in any management system, as well as an integrated one. Models of an integrated management system should also emphasize the need for no significant differences in the scope of the integrated systems, and a strong culture which supports the main requirements of TQM. 相似文献
