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

Several studies concluded that deep reflection is infrequently reached in student portfolios. An explanation for these disappointing conclusions might be that motivation for portfolio reflection determines the quality of reflection. This study aimed to examine the relationship between motivation for using digital portfolios and reflection. Participants were 156 eleventh-grade students in secondary education, whose motivation for composing a digital portfolio was measured by the motivation part of the Motivated Strategies for Learning Questionnaire. Portfolios of 37 of the 156 students were examined in terms of the amount and nature of reflection by means of a coding scheme based on Mezirow's model of transformative learning. On average, one-fifth (19.5%) of the paragraphs in a portfolio contained reflection, and paragraphs with deep reflection were hardly found (0.8%). It was concluded that motivation for composing a portfolio was fair, but not related to the amount and nature of reflection. This exploratory study gives rise to further research into factors that might influence the quality of portfolio reflection. 相似文献

A comparison is made of the standards in primary school mathematics in England and Cyprus, drawing upon national curricula, content of textbooks and data from international comparisons of attainment. Standards are conceptualised in three ways: expected, planned and realised. It is demonstrated that high expected and high planned standards, as set in national curricula and textbooks, are not associated with high realised standards. Four possible explanations are explored and policy issues associated with national standard setting are discussed. The value of setting national curriculum standards and targets by reference to comparative international data is raised. 相似文献
