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

It is unclear whether long-term aerobic (AT) or resistance (RT) training can improve insulin sensitivity (IS) beyond the residual effect of the last training bout in older women (54-78 years). Therefore, a group of nonobese, healthy older women underwent 6 months of AT (n = 8) or RT (n = 10), and the authors measured IS 4 days after the last training bouts using the hyperinsulinemic-euglycemic clamp technique. Women trained 3 days/week. AT consisted of 25- to 60-min sessions of walking/jogging at 60-95% of maximal heart rate. RT consisted of three sets of nine exercises repeated 10 times at 80% of 1 repetition maximum. AT decreased fat mass, whereas both AT and RT increased fat-free mass. Neither training program, however, improved absolute or relative rates of glucose disposal. The authors therefore concluded that nonobese, healthy older women should perform AT or RT on a daily basis in order to improve IS and maintain the improvement. 相似文献

This article explores key insights that economic theory can shed on the issue of no-fault divorce in the United States, addressing
modifications in the incentive structure of individuals that resulted from the legislative reforms of the 1970s. After stressing
the importance of correctly interpreting and classifying divorce laws, this work investigates the contributions of the theory
of property rights, the contributions of game theory and intra-household bargaining, and the contributions of general equilibrium
analysis in our understanding of how divorce laws work and what their impact is. By doing so, this exposé analyzes the theoretical
consequences of no-fault divorce on the decision whether to get married or divorced, on the characteristics of spouses and
divorcees, on divorce rates, and on marital-specific and non marital-specific investments. 相似文献

Collective and Unitary Models: A Clarification 总被引:3,自引:0,他引:3

In this note we identify and clarify a confusion that has arisen in the literature about the exact relationship between unitary
and collective models and what enters the Pareto weight and the sharing function. We suggest that we should denote as ‘unitary’
any model that leads to outcomes that satisfy the Slutsky conditions whether or not these outcomes depend on distribution
factors. In particular, income pooling is neither necessary nor sufficient for a unitary model. We also show that the presence
of prices or total expenditure in the sharing rule cannot be used as a test for a unitary model.

A new discrete family of probability distributions that are generated by the 3 F 2 function with complex parameters is presented. Some of the properties of this new family are studied as well as methods of estimation for its parameters. It affords considerable flexibility of shape which turns the distribution into an appropriate candidate for modeling data that cannot be adequately fitted by classical families with fewer parameters. Finally, three examples in the fields of Agriculture and Education are included in order to show the versatility and utility of this distribution. 相似文献

We propose a new method to estimate the cumulative hazard function and the corresponding distribution function of survival times under randomly left-truncated and right-censored observations (LTRC). The new estimators are based on presmoothing ideas, the estimation of the conditional expectation m of the censoring indicator. An almost sure representation for both estimators is established, from which a strong consistency rate and asymptotic normality are derived. It is shown that the presmoothed modification leads to a gain in terms of asymptotic mean squared error. This efficiency with respect to the classical estimators is also shown in a simulation study. Finally, an application to a real data set is provided. 相似文献
