尾矿库安全监测关键点

尾矿库是指筑坝拦截谷口或围地构成的、用以堆存金属非金属矿山矿石选别后排出的尾矿的场所，它是维持矿山正常生产的必要设施，也是金属非金属矿山的重大危险源。作为具有高势能的人造泥石流危险源，尾矿库一旦发生溃坝事故，将会给下游人民的生命财产安全造成巨大损失，给周边环境造成严重污染。

Safety metaphors and theories,a review of the occupational safety literature of the US,UK and The Netherlands,till the first part of the 20th century

The 19th century and first half of the 20th century is one of those periods in history of rapid economical, technical and social changes. There is an ongoing mechanization, followed by a movement to rationalize production and to make it cost effective. This has created a heavy burden of occupational deaths amongst workers. In this period occupational safety is developing into a professional field. Engineers are enclosing hazards and fencing heights, shaping up safety technique, and writing very practical publications on occupational safety. These publications, predominantly published in the United States, are leading to quite some safety related metaphors, with the iceberg and the domino’s as the most famous ones. Sociologists, psychologists, and physicians are more concerned with questions related to accident causation, and these specialists are conducting research leading to two different safety theories. Causes of occupational accident are found either in the workers’ capacity to handle hazardous situations, or in external causes, like very long working hours, dangerous machines and the increased pressures of work and speed of production. The Pittsburgh survey, the first extended analysis of occupational accidents in a steel district, strongly advocated the environmental hypothesis, while the so-called ‘individual hypothesis’ is favored by the American Safety First Movement, starting as a private initiative in 1906 by US Steel, and later spreading out over Western European countries. The British Industrial Fatigue Board has given the individual hypothesis its scientific justification. Despite scientific criticism just after World War II on the concept of accident proneness and ‘unsafe acts’, its popularity is not fading. Even nowadays the famous metaphors are still part of the vocational training of safety experts, also in The Netherlands. Apparently professional and scientific developments in occupational safety are belonging to two separate worlds. Before World War II, The Netherlands is not a leading country in occupational safety but a follower, first of France and the German speaking countries. After World War I its focus is directed towards the Anglo-Saxon countries.     

Explosibility,flammability and the thermal decomposition of Bisphenol A,the main component of epoxy resin

Bisphenol A is one of the basic compounds used in a synthesis of polycarbonates and epoxy resins. Its dust can create an explosive mixture with air under specific circumstances. Therefore, the main goal of this research was to determine explosion characteristics and flammability behaviour of this compound. The complete flammability characteristic requires the determination of the basic parameters of Bisphenol A under fire conditions including Heat Release Rate, speed of combustion, ability to ignite and the temperature of the decomposition range. To establish those parameters, a cone calorimeter was used. The explosion characteristics were tested in a 20-L spherical vessel. Minimum Ignition Energy was tested on MINOR II Apparatus which is a modified Hartman's Tube. In order to identify hazardous substances generated during a fire involving Bisphenol A, a simultaneous thermal analysis that combines thermogravimetry and differential scanning calorimetry was used. The substances obtained from the thermal degradation were analyzed by infrared spectroscope with Fourier transformation. Furthermore, the application of a Purser furnace and gas chromatography with mass spectrometry facilitated the identification of gaseous substances formed during the thermal degradation of Bisphenol A samples.     

天津大沽排水河疏浚前后沉积物生态毒性初步评价

沿天津大沽排水河设置16个采样点,于2009年3-5月和2009年9-11月分别采集疏浚前后共32份沉积物样品,采用发光细菌法评价其毒性效应.结果表明,疏浚前,25.0%的样品毒性等级为低毒,68.8%的样品毒性等级为高毒和剧毒,下游河段发光菌相对发光度均小于30.0%;疏浚通水半年后,37.5%的样品毒性等级为低毒,高毒和剧毒等级样品占总数的比例下降至18.8%.证明疏浚后沉积物对发光菌发光的抑制作用减弱,大沽排水河沉积物疏浚工程明显改善了大沽排水河的生态环境.     

Predictors of intentions to leave the ward,the hospital,and the nursing profession: A longitudinal study

The stages preceding and following the intention to withdraw from an organization have not been adequately examined. Data were collected at two time periods from a sample of 146 nurses working in a general hospital located in a large metropolitan area in Israel. Essentially, intention to withdraw from three levels — ward, hospital and profession — were examined. LISREL was used to test alternative longitudinal models for the best fitting set of linkages among variables. The findings supported a progression model of withdrawal intention. According to this conceptualization, a nurse first decides to leave the ward, then the hospital, and, finally, the profession. Theoretical and practical implications of the results were presented.     

Age,work experience,and the psychological contract

The purpose of the current paper is to examine the ways in which age and work experience shape how individuals experience psychological contract breaches. We first introduce the concepts of contract malleability (the degree to which individuals can tolerate deviations from contract expectations) and contract replicability (the degree to which individuals believe that their psychological contracts can be replicated elsewhere). Next, we discuss the variety of reasons why contract malleability and replicability become greater with age and work experience and how contract malleability and replicability may temper negative reactions to psychological contract breaches. We also address the different ways contract malleability and replicability mediate the relationships between age and work experience, on one hand, and exit, voice, loyalty, and neglect behaviors on the other. We consider the moderating effects of age similarity and dissimilarity here as well. The paper concludes with a discussion of the implications for future research designs and for managing older and more experienced workers. Copyright © 2009 John Wiley & Sons, Ltd.
