We explore issues of group decision making for reducing global environmental risk, with particular reference to the political dynamics surrounding international agreements on tackling climate change. Continuing political delays in deciding to reduce greenhouse gas emissions may make it necessary to resort to high risk and controversial geo-engineering solutions, such as injecting large amounts of sulfur dioxide into the stratosphere, despite the unforeseen, potentially catastrophic consequences that these entail. Advances in drama theory (dt.2) are used to analyze the prospects for agreement on reducing or stabilizing greenhouse gas emissions, following the Bali agreement of December 2007. It is concluded that Western nations and emerging economies are behaving like players in a game of “chicken”, each expecting the other to take on the main burden of emissions reduction. We judge it unlikely that either will play a full part until it is too late for emissions reduction alone to avert environmental catastrophe. At that point, parties will resort to geo-engineering “fixes”, despite the risks. However, all such forecasts are conditional on decisions made and attitudes taken by political leaders and the public. Our analysis serves to pinpoint the relevant decisions and attitudes.  相似文献

This article seeks to inform and enliven the debate on whether or not Britain should join the euro. The central focus of the article involves interviews with two leading economists, Professor Willem Buiter (Chief Economist and Special Counsellor to the President, European Bank for Reconstruction and Development) who strongly supports the case for joining, and Professor Patrick Minford (Professor of Applied Economics, Cardiff Business School) who takes the opposite stance. The article begins with an introduction which places the interviews in context and concludes with a final section summarising the central points of commonality and departure arising in the interviews with Professors Buiter and Minford.  相似文献

When faced with the need to protect dealer provision of promotional services for their products, manufacturers have continued to impose resale price maintenance (RPM) in preference to providing exclusive territories, even though the latter are legal while RPM is not. This paper compares RPM and territories, finding that RPM raises retail prices by less, but also supports less service provision than the exclusive territories alternative. Indeed, exclusive territories raise prices and generate more services than full manufacturer integration into distribution. This result calls into question the current contrasting legal treatment of territories and RPM.  相似文献

The current and expected future state of the American health care system creates much concern and anxiety at the national and individual level among Americans. This study is in response to the call of the Institute of Medicine to further study the lack of confidence among Americans about their future ability to receive high‐quality health care. This study compares perceived anxiety and its amelioration as a result of three possible health situations: illness with infectious disease, losing one's health and a breakdown of the health care system. This empirical study was conducted within the framework of conjoint analysis. We conducted an experimental design of ideas, identified attributes that increased or reduced anxiety in each of the three health‐related situations and then segmented consumers on the basis of their patterns of reactions to the attributes. We found that the highest anxiety was attributed to the breakdown of the health care system. The segmentation further suggested that the anxiety emerging from the breakdown of society's health care system generated a different extent of anxiety than that which emerged from one's illness or one's loss of own health. The attributes that drove anxiety across the health situations were, surprisingly, charities, one's company, the local hospital and supplemental insurance. Attributes that reduced anxiety differed among segments. The attributes were found to be: close friends, family, distribution of information by authorities and the belief in God. At a practical level, these data and patterns of response allow health care policy makers to enhance the coping ability of patients by understanding the nature of what reduces the anxiety of individual types of patients. The approach in this study provides a person‐centred system for communication and anxiety reduction that can be implemented as part of a public health policy.  相似文献

Drama theory differs from game theory in that it does not regard actors' preferences and perceived opportunities as fixed, but as capable of being changed by the actors themselves under the pressure of pre-play negotiations. Thus characters in a drama undergo change and development. A manyperson, multiphase theory of dramatic transformation is presented, showing how thecore of a drama (in the sense of game theory) is transformed by the interaction between the characters into a strict, strong equilibrium to which they all aspire. The process of dramatic transformation is shown to be driven by actors' reactions to various paradoxes of rationality; it is proved that when all these paradoxes have been overcome, a full dramatic resolution has been reached, satisfying actors' emotional and moral demands, as well as the demands of rationality.  相似文献

One area of business performance of particular interest to both scholars and practitioners is corporate social responsibility. The notion that organizations should be attentive to the needs of constituents other than shareholders has been investigated and vigorously debated for over two decades. This has provoked an especially rich and diverse literature investigating the relationship between business and society. As a result, researchers have urged the study of the profiles and backgrounds of corporate upper echelons in order to better understand this relationship.There is ample evidence that corporations have in recent years increased the proportion of outside directors on their boards. This has been partly in reaction to increased interest in the corporate social responsiveness of business organizations and suggestions that the board of directors could play a unique role in this area. The expectation on the part of practitioners, researchers, and governmental regulators is that outside directors will advocate greater corporate responsiveness to society's needs by playing a more active role in overseeing managerial decisions.The purpose of this study is to partially fill a void in the literature by determining whether or not these expectations are justified, particularly in the service industry. Data were collected as part of a larger cross-national study of corporate social responsibility. A multivariate analysis of variance (MANOVA) of the results of a survey of 307 board members (198 outside and 109 inside directors) indicates that outside directors exhibit greater concern about the discretionary component of corporate responsibility and a weaker orientation toward economic performance. No significant differences between the two groups were observed with respect to the legal and ethical dimensions of corporate social responsibility. Some explanations as well as limited generalizations and implications are developed.  相似文献

Abstract The objective of this research was to ascertain the gender-and ethnic-related factors that influence what one eats. This survey was conducted using a validated, pilot-tested questionnaire in 11 states and the District of Columbia, which were participating in the W-182 Western Regional Research project. The results indicated that the factors that influence what one eats differ by gender and ethnicity. Men were very much influenced by likes and dislikes, and by their spouse or significant other. Women were influenced by likes and dislikes, and health. Food likes/dislikes and concerns about health and weight were among the leading four factors for all ethnic groups. Food likes/dislikes were the top factor influencing what is eaten by 51% or more of Asians, Pacific Islanders, Caucasians and Hispanics. Concern about health was the top factor for 62% and 58%, respectively, of African Americans and Native Americans.  相似文献

The frequency of use and the marginal costs and marginal value products of mastitis control practices on somatic cell count (SCC) and milk yield are investigated. A survey of current management practices is combined with Dairy Herd Improvement production information to determine the relationships between milk yield, SCC, management practices, and production and producer characteristics under field conditions. The relationships are modeled and compared at the cow and herd level. A moment-generating approach is used in the herd model to determine which, if any, practices are risk reducing. The SCC for an individual cow is a better indicator of milk production lost due to mastitis than is a bulk tank SCC. Most recommended mastitis control practices are estimated to be economically beneficial, but some common practices are found not to be economical, and questions are raised about dry cow treatment. On a examiné la fréquence à laquelle on recourt aux pratiques de lutte contre la mammite, de même que les couts et les avantages marginaux de ces dernières en ce qui concerne la numération des cellues somatiques et le rendement laitier. On a combiné une enquête sur les pratiques zootechniques actuelles aux renseignements sur la production extraits du Programme d'amélioration des troupeaux laitiers en vue de déterminer les relations qui existent entre le rendement laitier, la numération des cellules somatiques, la conduite du troupeau ainsi que les caractéristiques associées à la production et aux producteurs, sur le terrain. On a ensuite modélisé ces relations et on les a compareées entre les animaux et les troupeaux. Pour le modèle touchant les troupeaux, on s'est servi d'une approche générant des moments, pour déterminer si une pratique quelconque diminuait les risques. La numération des cellules somatiques chez la vache est un meilleur indicateur du volume de lait perdu à la suite de la mammite que la numération des cellules somatiques dans la citerne. La plupart des méthodes de lutte contre la mammite recommendées offrent un avantage économique, mais certaines pratiques courantes ont l'effet contraire et on s'interroge sur l'utilité de traiter les vaches taries.  相似文献

Perspectives from business and academia on the relative importance of various skills and attributes were compared. The perspective from academia came from the University of Guelph learning objectives and the AEB simple and complex skills required for undergraduate majors. A survey of Canadian agribusiness firms, including governmental agencies, provided the business perspective. Different types and sizes of businesses were consistent in ranking the relative importance of the various skills and attributes. The rankings by business were also consistent with the hierachial learning objectives from the University of Guelph and the disciplinary skills from the AEB. The hypothesis that business and academia are more convergent than divergent as to what our students should know is supported by these results.
Both business and academia rank communication skills highly. Business ranks personal qualities slightly higher than communication skills, but universities recognize that they can only screen for personal qualities, as opposed to the skills that they can enhance through education. Relatively low rankings of technical, computer and quantitative skills and experience should not be interpreted to mean they are unimportant, but rather that they are necessary but not sufficient for entry-level employees to succeed in agribusiness firms.  相似文献
