Industries that deal with hazardous systems are faced with the task of managing a spectrum of risks within resource contraints. They have essentially two options that can be combined in a global risk-management strategy: insurance (loss sharing) and risk mitigation through technical and organizational measures. In this article, global risk-management strategies based on probabilistic risk analysis and its extension to include management factors are described. Some issues and solutions are illustrated through practical examples, drawn mostly from the recent research of the Industrial Engineering Risk Research Group at Stanford (the tiles of the U.S. Space Shuttle, offshore platforms, marine pipelines, and anesthesia in modern hospitals). 相似文献

In a previous paper Gastwirth shows that a broad family of measures of inequality can be accurately estimated when the tax data are known in groups (more precisely, when we know the number of returns in each of several class intervals and their corresponding average income). In the present paper we show that some measures of the preceding family can be unbiasedly estimated when the tax data are individually known for a sample from the population. Specifically, we construct unbiased estimators of a particular measure of inequality in the samplings with and without replacement, and in the stratified samplings with and without replacement. 相似文献

Départ Des Enfants Et Contraction Des Familles D'Après Les Recensements Canadiens De 1971 Et De 1981
Yves Péron Evelyne Lapierre-Adamcyk Denis Morissette 《Revue europeenne de demographie》1986,2(2):155-175
Censuses do not usually collect information on the departure of children and the consequent contraction of the family; however, they sometimes do include useful information on these phenomena and their evolution. On these questions this article presents a new use of the 1971 and 1981 Canadian censuses. From the analysis, it is estimated that the timing of children's departure from their family of origin was almost the same in 1981 as in 1971; median age at departure was identical: 20.5 for women and 22.3 for men. Broken families, more numerous than in the past, become contracted earlier than unbroken families; among unbroken families, the contraction phase started earlier in 1981 than in 1971 among large or medium-sized families while it began later among small families. The method developed here succeeds with the Canadian data in palliating the lack of surveys; it would be interesting to test it on data from other Western societies. 相似文献

Traditional applications of management science aiming at solving specific decision-making problems are claimed to be often of an aggressive nature. They represent an intrusion into the life space of the managers who are supposed to use them and in many cases are consequently rejected. In the light of the evolution of marketing and corporate modelling over the last twenty years, the authors propose a new supportive approach for management science applications which is user-oriented rather than task-oriented. The characteristics of the aggressive and supportive approaches are contrasted, and an example of a supportive management science application for marketing strategy formulation is described. 相似文献

This article illustrates a teaching case in which a marriage and family therapy (MFT) trainee learned to develop cultural sensitivity toward same-sex couples despite religious beliefs that put her at risk of discriminating against that population. The case took place during a marriage and family therapy ethics course in the spring of 2003. From two first-person perspectives, the authors illustrate the processes that facilitated the student's change, addressing the class activities, discussions, and pivotal moments of teaching and learning that promoted the student's cultural competency and helped her to resolve this personal and ethical dilemma. A set of classroom techniques (creating a safe environment, using a stance of curiosity, finding alternative learning formats, extrapolating ideas from multiple sources, and capitalizing on students' experiences outside of class) used in the case are detailed throughout the article. 相似文献

Taking an active part and responsibilities in one's own life is not always easy, particularly at adolescence, which is a very important period in which people progressively find their identity and life project. This article describes the social validation analyses of a Belgian self-determination curriculum that was adapted from a French-Canadian curriculum. It was done with the participation of adolescents with intellectual disabilities, teachers, and experts from the field. Overall, results indicate a satisfying to very satisfying appreciation of the social utility of the training manual. The findings also highlighted that the curriculum actually supports the conceptual framework of self-determination. 相似文献

Two studies investigated the effects of a video lottery terminal stopping device on gamblers thoughts and behavior. This structural characteristic allows players to voluntarily stop the spinning of the reels. The first study investigated the effect of this device on the development of illusions of control. It was predicted that players using the stopping device would believe that (1) symbols displayed could differ depending on when the game is stopped, (2) there is a possibility of controlling the outcome of the game, (3) skills may be a factor influencing the results, and finally (4) a stopping device would improve the probability of personal success (i.e., developing the illusion of control). The second study aimed to further evaluate the effects of the stopping device on gambling behavior. It was hypothesised that using the stopping device would encourage players to increase the number of games played in a session. Results confirmed all predictions and showed that offering a stopping device on video lottery terminals modifies gamblers cognition and behavior. The theoretical and practical implications of these results are discussed in the context of responsible gambling policies. 相似文献
