This is a study of a well-known controversy in computer science, between artificial intelligence and neural networks researchers. It examines claims made by participants in the field that the controversy was triggered, shaped and finally resolved in connection to activities of state research agencies, particularly the US Department of Defense Advanced Research Projects Agency (ARPA). In contrast to these claims, this account concludes that, although ARPA's relations to the controversy among researchers were important, they were indirect. This study thus beings the analytical resources of studies of scientific controversy to bear on a domain which has so far gone largely unexamined in studies of 20th-century controversies - namely, state research policy and management. The account is based on contemporary documents, historical literatuare, and interviews with researchers and ARPA officials.  相似文献

Most analyses of multicultural children's books concentrate on published works by white authors and the implications of their depictions of non-white characters. This article explores the production process of multicultural children's literature. The differences between multicultural and culturally conscious literature are discussed. The production and distribution processes of children's books are described. Interview data is used to highlight areas of these systems which constrain the production of books by non-white authors.  相似文献

This paper takes a preliminary look at the hybridization of museums – the creation of a variety of mixed forms of governance incorporating both public and private governing authorities. Using data from three national surveys of American museums, the analysis documents the mix of types of governing authority and demonstrates how this mix varies across location, over time, and by museum type. The paper then estimates the extent of hybridization using several different indicators and speculates about its implications. The United States offers a particularly informative case because the general view is that American museums are (1) either public or private and (2) predominately private. While the second part of this view may still be a useful characterization of American museums, the first is no longer a particularly helpful way of understanding American museums, or, by extension, other cultural institutions, American or not. It is increasingly necessary to view cultural institutions through the lens of hybridization rather than privatization in order to improve our ability to document and predict their institutional behavior.  相似文献

Communicators achieve increased rule consensus as they use talk to overcome problems. Two kinds of talk seem especially useful to increasing consensus: remedial talk, which uses rules to correct past problems; and legislative talk, which uses rules to propose guides for future conduct.  相似文献

A survey of 289 pastors from, three major denominations found that clergy demonstrate a relatively high level of gerontological knowledge in comparison with other reference groups, but that their concepts of aging are affected by a number of consistent stereotypes and inaccuracies that may negatively influence their ministry among older adults. This study addresses the major stereotypes identified by the Facts on Aging Quiz, summarizes gerontological education needs described by the respondents, and draws implications for gerontological training as part of seminary education.  相似文献
