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.     

Constructive controversy,the Vroom-Yetton model,and managerial decision-making

Empirical tests have indicated that following the Vroom-Yetton Normative Model of leadership predicts reliably to successful managerial decision-making. However, it does not consider the kind of social interaction among decision makers. Recent experiments have demonstrated that controversy constructively discussed can facilitate decision-making. To see whether constructive controversy can supplement the Vroom-Yetton model, 58 managers enrolled in an executive-level MBA programme described a successful and unsuccessful decision-making experience by answering the Vroom-Yetton questions and by indicating the extent those involved in making the decision experienced constructive controversy. Results indicate that both the Vroom-Yetton model and constructive controversy are significantly related to successful decision-making. A regression analysis indicated that constructive controversy accounted for 45 per cent of the variance of decision success whereas the Vroom-Yetton model accounted for 5 per cent. While the Vroom-Yetton model is useful at the preplanning stage for choosing a decision style, much greater contribution is provided by constructive discussions of opposing opinions when actually generating the decision.     

广东汕头市农业土壤和蔬菜铅含量及健康风险评估

重金属元素铅的危害已经引起人们的广泛关注,为了得到汕头市土壤及蔬菜铅污染的状况,选取了该市115个土壤样品及34个蔬菜样品进行铅含量分析.研究发现,汕头市土壤样品铅含量差异较大,最高含量为110mg/kg,最低含量则为12.1mg/kg,极差达到97.9mg/kg.56.52%的土壤样品铅含量超过国家土壤环境质量标准,表明该市土壤铅污染存在普遍性,且各区(县)土壤铅含量极不均匀.汕头市蔬菜样品铅含量全部超过国家食品卫生标准(GB 14935-94),不同蔬菜品种对铅的富集能力均较强,蔬菜样品铅最低含量为5mg/kg,最高含量为85mg/kg,分别为国家标准限值的5倍和425倍.经分析认为,该市铅污染源主要来自工业"三废"排放、大量含铅农药的使用、汽车尾气排放以及大气沉降等.还对汕头市民通过食用蔬菜而导致的铅暴露进行了健康风险评估,结果表明该市居民使用蔬菜存在较大的健康风险.     

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.     

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.     

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.
