Scholars, commentaries, guide books, and people “on the street” seem to agree and take for granted that natural history museums are mainly aimed at children. Nevertheless, no studies have specifically investigated the public image of natural history museums. In this study, we provide quantitative evidence that natural history museums are indeed seen by the public as being primarily aimed at children and families with children, and we discuss the consequences that this fact has for the potential role that natural history museums could have in promoting science literacy and for the perception of science in general. 相似文献

In a time with a heightened focus on how museum architecture and exhibition design shapes the museum visit, the entrance space of museums, the museum lobby, is remarkably absent from the museum literature and research. Still, the museum lobby is the first encounter visitors have with the museum and the last impression that they take home and share with others. This article analyzes museum lobbies as communication spaces in order to identify the different functions afforded by such spaces. In an explorative study of five Danish museum lobbies, we offer a preliminary categorization of these functions that can be compared at a general level. Concrete examples will be used to discuss general issues such as the adaptive borders of lobby spaces and the counteracting effects of design. We suggest that the preliminary categorization provided here can form a foundation for further studies resulting in practical suggestions for design improvements. 相似文献

This paper started life in September 2014 as a submission by the International Publishers Association (IPA) to the Office of the UN High Commissioner for Human Rights. It is the IPA’s view that human rights and intellectual property rights are not only compatible, but also mutually supportive and interdependent. Copyright in particular, is a success story. It has proven to be a powerful tool to strengthen science and culture, improve participation in them, and provide a legal framework that confers such rights and enables policies to promote them. This is particularly true in the online environment, where copyright laws enable science and culture to prosper, and are giving scientists, creators and publishers new economic ways of exercising their profession, creating the diversity of content and services that a rapidly growing majority of the world’s population is able to participate in. Copyright creates a marketplace that empowers citizens, and reduces the need for government interference with culture and science, a welcome state of affairs, in particular from the human rights perspective. 相似文献

In economics the Research Papers in Economics (RePEc) network has become an essential source for the gathering and the spread of both existing and new economic research. Furthermore, it is currently the largest bibliometric database in economic sciences containing 33 different indicators for more than 30,000 economists. Based on this bibliographic information RePEc calculates well-known rankings for authors and academic institutions. We provide some cautionary remarks concerning the interpretation of some provided bibliometric measures in RePEc. Moreover, we show how individual and aggregated rankings can be biased due to the employed ranking methodology. In order to select key indicators describing and assessing research performance of scientist, we propose to apply principal component analysis in this data-rich environment. This approach allows us to assign weights to each indicator prior to aggregation. We illustrate the approach by providing a new overall ranking of economists based on RePEc data. 相似文献

Assessing implementation allows for a better understanding of an intervention's effects and the mechanisms that influence its impact. Two main areas of implementation are (a) the quality with which an intervention is delivered and (b) instructors’ adherence to the programmed intervention. The current study used data from a kindergarten mathematics intervention program to (a) examine if and how treatment adherence was associated with implementation quality and (b) explore implementation measures’ relation to student mathematics outcomes. Results indicated high implementation scores across time for both adherence and quality. Neither treatment adherence nor implementation quality was found to relate to a general outcome measure of student mathematics achievement; however, both were similarly related to the curricular-aligned measure. 相似文献

This study examined whether having vulnerable friends helps or hurts victimized and depressed (i.e., vulnerable) adolescents and whether this depends on classroom supportive norms. Students (n = 1461, 46.7% girls, 93.4% Han nationality) were surveyed four times from seventh and eighth grade (Mage = 13 years) in 2015 and 2016 in Central China. Longitudinal social network analyses indicated that having vulnerable friends can both hurt and help vulnerable adolescents. Depressed adolescents with depressed friends increased in victimization over time. Victimized adolescents with victimized friends increased in victimization but decreased in depressive symptoms. These processes were most likely in classrooms with high supportive norms. Having friends and a supportive classroom may hurt vulnerable adolescents' social position but help victims' emotional development. 相似文献
