This paper studies aspects of sequential choice (and elimination) through the ‘routewise’ application of choice. (A choice is a mapping of the subsets of a set X into their respective subsets.) This approach sheds some further light on the ‘path-independence’ of choice, as well as on the logical structure of several rationality criteria for choice, as expressed through the properties of the comparison (or preference relation) revealed by a choice. The results bear particular relevance to the theory of collective choice.  相似文献

A program to train inmates as paralegals was established at a large state prison in the Midwest. Qualified inmates were randomly assigned to the training or to a control condition. Both groups were administered measures assessing legal knowledge, the use of legal knowledge, attitudes about the criminal justice system, and self-perceptions before and after training. The trainee group showed a significant increase in its amount of legal knowledge after training. Members of the trainee group also reported a significant increase in the number of other inmates requesting aid from them on legal problems. In addition, interviews were conducted with two random samples of the general inmate population, before and after the paralegal training program. These interviews revealed strong support for the training program, and this support increased over the period of the program. Limited data on longer-term effectiveness of the paralegal's performance in the prison legal aid clinic and in paralegal jobs following parole supported the positive, shorter-term results.  相似文献

Automation and computers could improve the profitability of a manufacturing organization. While automation is primarily used to perform physical manufacturing tasks, computers are used for both information-type tasks and physical manufacturing tasks. If the manufacturing operations and personnel, as well as the flow of information, material, and energy, could be integrated to perform well-planned sequences of tasks to manufacture families of products in cells, the rewards would be enhanced profitability, quality, and safety. Such an integration is generally termed “computer-integrated manufacturing” (CIM). This paper summarizes a survey designed to determine the current and future service/training needs in CIM-related technologies of Florida manufacturing industries. It also identifies a role for a technology transfer center in offering training/technical services in CIM or related technologies to these companies.  相似文献
