We investigate the degree to which people in a shopping mall express other‐regarding behavior in the dictator game. Whereas many studies have attempted to increase the social distance between the dictator and experimenter and between the dictator and recipient, we attempt to minimize that social distance between random strangers by video recording the decisions, with the permission of the dictators, to display their image on the Internet. Offers made by dictators are high, relative to other experiments, and a nontrivial number give the entire experimental windfall away. However, a nontrivial number of people keep everything as well.  相似文献

Logistics management in grain marketing has become very important with the maturity of the industry. This is particularly critical in the Canadian grain marketing system, which has experienced disruptions for various reasons over many years. These problems have been the topic of numerous industry evaluations, have resulted in a complaint about service obligations during the 1996–97 crop year, and were addressed by the Estey Commission. A detailed model of the Canadian grain logistics system is developed in this paper to evaluate factors that cause disruptions, as well as the effect of several important logistics and marketing strategies on system performance. The results illustrate that there is sufficient randomness throughout the various functions of the system that it is expected that demurrage at the west coast would periodically be an important cost. The frequency of service disruptions and demurrage are affected by several factors, including the distribution of tough and damp grains, mis‐graded grain and the level of exportable supplies. Several strategic variables affect system performance. These include the aggressiveness in selling relative to capacity and the level of beginning port stocks. La gestion de la logistique dans le commerce des céréales a acquis une grande importance maintenant que ce secteur a atteint la maturité. C'est particulièrement important dans le système canadien de mise en marché des céréales lequel, pour diverses raisons, a essuyé bien des perturbations ces dernières années. Les problèmes en cause ont fait l'objet de nombreuses évaluations du secteur. Ils ont même abouti au dépôt d'une plainte sur les obligations de service dans la campagne agricole 1996–1997 et ont étéétudiés par la Commission Estey. Dans la présente communication nous avons construit un modèle détaillé du système canadien de logistique du marché des céréales ainsi que de l'effet de plusieurs stratégies importantes de logistique et de commercialisation sur la performance du systeme. Les résultats obtenus montrent qu'il y a suffisamment d'aléatoire dans les diverses fonctions du systeme pour conclure que les frais de séjour à quai sur la côte ouest seraient périodiquement un important poste de dépense. La fréquence des perturbations des services et les coûts a quai sont associés à plusieurs facteurs dont la livraison de grain gourd et humide, de grain mal classé et le niveau des disponibilités exportables. Plusieurs variables stratégiques influent sur le fonctionnement du système, notamment l'agressivité manifestée dans la vente par rapport aux stocks disponibles et le niveau des stocks disponibles dans les ports au début de la campagne d'exportation.  相似文献

Exploratory case study research was initiated to study the evolution of management information systems and their use in operational and strategic decisions. The unit of analysis was the management team on farms with innovative or successful information systems. Human factors, such as an analytical nature and commitment to lifelong learning, were perceived to be the most important common elements. Production variables often were critical success factors. Managers annually developed financial statements; enterprise and "what if" analyses were conducted regularly. Learning about questions that innovative producers have difficulty addressing was time-consuming but instructive with respect to research and educational needs.  相似文献

As many cases studies show, successful public health measures are being implemented in many places around the globe, and country-level mortality has fallen significantly in recent decades in all but a few countries. Are the two linked? Does development assistance for health (DAH) improve, on balance, recipient countries’ mortality trajectory? Using a new data source containing DAH on 96 high mortality countries, the regression analysis shows no effect of DAH on mortality. Other types of aid, including water development, also have no effect. Economic growth, on the other hand, has a strong negative effect on mortality. These findings confirm and build upon recent work by Williamson (2008) and are shown to be robust to a variety of sensitivity analyses and alternative model specifications and estimation methods.This analysis also shows that the effectiveness of DAH has not increased over time, even as the level of that funding has increased fourfold, though spending on infectious diseases and family planning may have caused small reductions in mortality. Furthermore, even though it is encouraging that DAH has tended to go where the need is highest, it also goes to states that have experienced the greatest mortality reductions in the recent past. In other words, DAH appears to be following success, rather than causing it.  相似文献

John Stuart Mill proposed that all policy precepts, be they in the areas of morality or prudence or aesthetics, are all subordinate to the precepts of the Art of Life. The value which he assumes in defining the Art of Life is the Principle of Utility. This principle, being normative rather than fact, can admit of no proof based solely on deductive inference. Yet Mill proposed considerations that he believed capable of rationally persuading one to accept his principle as the basic principle for the Art of Life. This paper aims to evaluate this argument. In particular, it tries to show that a crucial step, often thought to be a logical howler, is not to be so simply dismissed. It is shown that if one accepts certain theses from Mill's philosophy of science and of social science, concerning the composition of causes, then the crucial step is fully justified. It is also suggested that these theses of Mill's philosophy of science are mistaken. So Mill's proof of utility is, after all, unsound, but the reconstruction proposed shows it to be much more plausible and much more philosophically interesting than is often thought.  相似文献

The phenomenon of mass fun running in Britain dates from the early 1980s and displays much of the ideology of the ‘Sport For All’ campaign. While running as an activity can be viewed as a natural pastime, the notion of mass jogging, as exemplified by the Great North Run and the London Marathon, is more difficult to comprehend and requires further analysis. This paper argues that the mass fun run is an example of the ‘Society of Spectacle’: a commercial creature which is heavily reliant on media coverage and sponsorship and which serves as an endorsement and symbol of postmodern society. The media stresses the ‘tradition’ of such events and uses them as images of human decency and national unity. Yet the relationship between audience, participant and spectacle remains fragile and dependent upon commercial considerations.  相似文献
