No professional sports group ever achieved acceptance as widespread within a single decade's span as the American Football League (AFL). This study chronicles how the AFL used public relations strategies and tactics to garner public acceptance, which in turn helped convince the older National Football League (NFL) to merge with the upstart league. This study will further the understanding of how trade associations use public relations as an image-building device, as well as address a deficiency in the study of sports public relations.  相似文献

A popular concern is whether the managers of nonprofit enterprise are accountable. This article considers accountability in the context of three questions. First, how do groups establish a basis on which to hold managers acountable? Second, to whom should a manager be accountable? Third, can a person or group make it important to a manager to act in the best interests of the person or group? These three questions are addressed by the fields of public choice theory, social choice theory, and principal-agent theory, respectively. A cynical way of summarizing the seminal findings in these areas of research is that public choice theory proves that groups will be unable to form, social choice theory proves that once a group forms, it will be unable to make good decisions, and principal-agent theory proves that a decision, once reached, is impossible to implement. A more optimistic view is that the problems identified by these research findings contain the seeds of their own solution, and that thereby valuable lessons for nonprofit managers can be adduced.  相似文献

Several recent studies give conflicting evidence on whether market power associated with industry concentration is an important source of union rents. Using a 1977 sample of 327 four-digit manufacturing industries, we re-examine the issue with a regression analysis that allows for differential union effects on price-cost margins across three levels of concentration. Large and small firm as well as industry average price-cost margins are analyzed. The results reaffirm those of Hirsch and Connolly (1987), who conclude that the effect of unions on profits is independent of market structure, and thus market power is not an important source of union rents. We find that unionization: (1) reduces industry profits in all three concentration groups with statistically insignificant differential effects, and (2) has a greater negative effect on the profits of large firms than it does on the profits of small firms, regardless of the concentration category. We benefited from the comments of an anonymous referee. Any remaining errors are our own.  相似文献

This paper focuses on interdisciplinary and interorganizational concerns which are involved in the development of technology which will be of use to physically disabled persons. The paper is divided into five parts: (1) The concepts, 'interdisciplinary' and 'interorganizational' are described and defined. (2) Then, a number of concerns and problems involved in interdisciplinary and interorganizational work are identified. (3) From parts 1 and 2, an interdisciplinary/interorganizational framework is developed. (4) This framework is then used to analyze some problems and to examine possible solutions, focusing on the development of technology for physically disabled persons. (5) The paper ends with conclusions and recommendations.  相似文献

Despite the widespread conviction that the mass media tend to “blow risks out of proportion,” the question has received little systematic attention. The mass-media literature also presents the opposite argument, namely that the media minimize the kinds of reporting that might upset large-scale capitalistic industries. Still other perspectives hold, on the one hand, that media reports tend to have more subtle anti-technology effects, created by “even-handed” coverage and on the other hand, that reporters give “establishment” figures the opportunity to “keynote” or “put the facts in perspective” in ways that exert a subtly pro-technology effect. Drawing on a systematic sample of 128 hazard events developed by researchers at another university and factually summarized by Lexis -Nexis , we analyze the effects of emotionalism on actual levels of coverage; a variety of analyses show that the only variables to exert significant effects are those that involve objective information, such as the number of casualties or the level of damage created. Given the argument that the effects of emotionalism can be conveyed in ways that are largely independent of the facts, e.g., by headlines, photographs, and “loaded” words, we next compare the emotionalism conveyed by factual summaries vs. the original stories and headlines. Even for incidents involving nuclear and/or toxic hazards, we find the net effect of the full stories is to lessen the emotionalism. Overall, the hypothesis receiving strongest support is that the “keynoting” helps create an overall impression that the “responsible authorities” are acting more responsibly than might be assumed on the basis of factual summaries alone. The widespread impression within the technical community, while understandable, may well have as much to do with the selective perceptions of scientists and engineers as with the actual pattern of media reporting.  相似文献

Military courts have had to face the issue of compulsive gambling in criminal court-martial proceedings. The military recently switched from the liberal ALI definition of insanity to the much more stringent standards of the federal Insanity Defense Reform Act. However, military courts have not even allowed in expert testimony, holding the relevance of compulsive gambling has not been generally accepted in the scientific community. The rules involving extenuation or mitigation in sentencing allow much more leeway. Although compulsive gambling cannot be used as the basis for a defense of insanity in military courts, defense lawyers will continue to raise the issue in attempting to obtain lesser punishments for their military clients.B.S.

A methodology for partially ordering a set of multivariate observations is introduced. The method depends on an iterative reapplication of singular value decomposition (SVD) to partition the data into simply ordered subsets. Five measures of the fiscal capacity of states are analyzed to decide whether a majority can be simply ordered. Partial-order analysis uncovers a group of 38 states which can be simply ordered, a second group of five which can also be simply ordered, but not with the other 38. The remaining eight have no simply-ordered subgroup.  相似文献
