A 14-h night-shift in the control room of a fire brigade

All 29 operators in the control room of a fire brigade performed test sessions during work and leisure time at 2-h intervals on a day with a 14-h night-shift, a day off and a day with a 10-h morning shift. The test sessions consisted of a visual search choice reaction time test and two Sternberg memory search tests (1 or 5 letters had to be memorized). Furthermore, the operators recorded their oral temperature and their subjective alertness before each test session. The subject also kept a diary of work and sleep times for 14 days. The circadian rhythm of body temperature was hardly changed by a single night-shift. Parallel to the body temperature, the subjective alertness fell significantly during the night-shift reaching a minimum value at 06:00 h. The mean reaction times increased non-significantly at the end of the night-shift and the results of the two Sternberg memory search tests showed no significant trends. The sleep of the operators after the night-shift was on average reduced to 5 hs 34 min. The results of subjective rating of alertness and reaction time test are interpreted as effects of the combined influences of circadian rhythmicity, sleep loss and time on professional task. Most results support the conclusion that a 14-h night-shift without extensive breaks is not acceptable.

基于DEA模型评估江西省五市政府绩效实证研究

地区政府绩效评估自80年代以来日益受到重视,其评估指标体系不断完善,评估手段也日趋多元化。在以往的地方政府绩效相对有效性的评估中,往往很难兼顾评估的综合性和客观性。鉴于此,文章尝试应用DEA模型,在2004年8月国家人事部《中国地方政府绩效评估》课题组提出的33评估体系的基础上,选用代表性指标,对江西省人均GDP位居前五位的南昌、九江等五个市的政府绩效进行评估,得出一些结论并提供若干政策建议,从而进一步说明DEA模型评估政府绩效的有效性及适用范围。     

不同类型绩效考核对员工考核反应的差异性影响——考核目的视角下的研究

本文旨在探讨不同类型绩效考核对员工考核反应(Appraisal Reaction)造成的差异性影响。根据考核的两种基本目的(发展型和评估型),将绩效考核划分为交易型、承诺型、合作型和放任型四种类型。通过对武汉市308名企业员工的调查发现,在不同类型的绩效考核下,员工对考核的直接反应和间接反应都有显著性差异。整体而言,在合作型绩效考核下,员工的考核公平感会表现得更高,任务绩效也会更好;在放任型绩效考核下,员工的考核满意度最低。进一步的协方差分析和多变量方差分析也基本证实了该结果。     

国外高等教育评估制度对我国高教评估的启迪

美、英、日三国各具特色的教育评估制度,对建设和完善具有中国特色的高等教育评估制度有重要的启示作用,借鉴国外高教评估体制的长处和经验,指出我国教育质量评估主要应由民间评估机构进行;高校办学质量评估中教育质量与科研质量应分别评估;把学科建设作为评估的主要内容;评估标准能充分体现高校高度的自治性。同时分析了我国高教评估的现状和发展趋向。     

Testing for Upper Outliers in Gamma Sample

The problem of multiple upper outlier detection in gamma sample is considered. Balasooriya and Gadag (1994 Balasooriya , U. , Gadag , V. ( 1994 ). Tests for upper outliers in the two-parameter exponential distribution . J. Statist. Computat. Simul. 50 : 249 – 259 .[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) proposed a location and scale invariant test based on the test statistic Z _k for testing the k upper outliers in two-parameter exponential sample. In this article, the test statistic is extended for gamma sample and the null distribution of the statistic is obtained. A simulation study is carried out to compare the performance of the tests and is found that the test based on Z _k is more powerful than the test based on the test statistic proposed by Jabbari Nooghabi et al. (2010 Jabbari Nooghabi , M. , Jabbari Nooghabi , H. , Nasiri , P. ( 2010 ). Detecting outliers in gamma distribution . Commun. Statist. Theor. Meth. 39 : 698 – 706 .[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]).     

Testing of Suspected Observations in an Exponential Sample With Unknown Origin

The problem of multiple upper outliers in two-parameter exponential sample is considered. A test statistic is proposed to identify the outliers at the upper end of the sample. The null distribution of the test statistic is obtained and the critical values are found. The performance of the test is also compared with the earlier work.     

Storage Life Prediction for a High-Performance Capacitor Using Multi-Phase Wiener Degradation Model

Capacitance is a critical performance characteristic of high-voltage-pulse capacitor which is used to store and discharge electrical energy rapidly. The capacitors usually are stored for a long period of time before put into use. Experimental result and engineering experience indicate that the capacitance increases with storage time and will eventually exceed the failure threshold, which means that the capacitor may fail during storage. This is a typical mode of degradation failure for long storage products. Further, the capacitance degradation path can be extrapolated in several stages based on the shifting characteristics. That is, the capacitance increases slowly or fluctuates in the initial storage stage that lasts about three months. Then it increases sharply in the middle stage which lasts about four months. After the two stages, the capacitor enters into the third stage in which capacitance increases constantly. This degradation phenomenon motivates us to study the storage life prediction method based on multi-phase degradation path model. The storage performance degradation mechanism of high-voltage-pulse capacitor was investigated, which provides the physical basis for multi-phase Wiener degradation model. Identification procedure for the transition points in the degradation path was proposed using maximum likelihood principle (MLP). The result of Kruskal-Wallis test which is the method to test whether two populations are consistent or not in statistics showed that the transition points are statistically effective. Other parameters in the multi-phase degradation model are estimated with maximum likelihood estimation (MLE) after the transition points have been specified. The multi-phase Inverse Gaussian (IG) distribution for storage life was deduced for the capacitor, and the point and interval estimation procedure for reliable storage life are constructed with bootstrap method. The efficiency and effectiveness of the proposed multi-phase degradation model is compared with storage life prediction under single-phase condition.
