This article discusses best-selling science books, the characteristics of the audience for popular science books, and the role of books within science popularization and science education. Best-selling science books have been rare, but generally readable. Regional books, also important sources of scientific information, aim at much smaller, far more price-sensitive audiences. Many successful regional, nontechnical science books are readable, heavily illustrated, and in some cases, cross-disciplinary. To increase the attentive audience for scientific information, improvement in science education is necessary, and the most efficacious role for scientific institutions may be the production of materials that can be easily incorporated into school curricula. He is the author of several nontechnical guides to the geology of Kansas and teaches science writing at the University of Kansas School of Journalism and Mass Communications A slightly different version of this paper was presented at the joint meeting of the Association of Earth Science éditors, European Association of Editors, and the Council of Biology Editors, Ottawa, Ontario, September 1989.  相似文献

One of the most commonly observed features of the organization of markets is that similar business enterprises cluster in physical space. In this paper, we develop an explanation for firm co-location in high-technology industries that draws upon a relational account of new venture creation. We argue that industries cluster because entrepreneurs find it difficult to leverage the social ties necessary to mobilize essential resources when they reside far from those resources. Therefore, opportunities for high tech entrepreneurship mirror the distribution of critical resources. The same factors that enable high tech entrepreneurship, however, do not necessary promote firm performance. In the empirical analyses, we investigate the effects of geographic proximity to established biotechnology firms, sources of biotechnology expertise (highly-skilled labor), and venture capitalists on the location-specific founding rates and performance of biotechnology firms. The paper finds that the local conditions that promote new venture creation differ from those that maximize the performance of recently established companies.  相似文献

Facebook is a frequently used Computer Mediated Environment (CME) for students and others to build social connections, with identities and deposited self-expression. Its widespread use makes it appropriate for consideration as an educational tool; though one that does not yet have clear guidelines for use. Whether a social networking site can be used for educational objectives remains largely unexplored as a research question. This paper discusses a study conducted at the University of Auckland and at Manchester Metropolitan University on how their students use Facebook, and its impact on their social and academic lives. Using theories of social capital and knowledge management, we explore some potential educational uses of Facebook. Guidelines are included for the educational use of Facebook by tutors in a university environment. These include both positive recommendations and activities and approaches to avoid; and include educational, administrative and legal issues.  相似文献

This paper emerged following recent research into the causes and effects of occupational pressures on primary headteachers in West Berkshire. The heads concerned were grouped according to a measure of the Type A/Type B personality dichotomy and their reported vulnerability to particular pressures related to this variable. Some conclusions are noted as are reported effective coping devices. The paper concludes with a brief examination of the implications of the research findings for local authorities.  相似文献

Online participatory platforms are introduced to boost citizen involvement in political decision-making. However, the design features of these platforms vary considerably, and these are likely to affect how prospective users evaluate the usefulness of these platforms. Previous studies explored how prevalent different design features are and how they affect the success of platforms in terms of impact, but the attitudes of prospective users remain unclear. Since these evaluations affect the prospects for launching successful participatory platforms, it is imperative to assess what citizens want from such digital possibilities for participation. This study uses a conjoint experiment (n = 1048) conducted in Finland that explore the impact of seven design features: Discussion possibilities; Interaction with politicians and experts; Information availability, Aim of participation; Identity verification; Anonymous participation and Accessibility. Furthermore, it is examined whether the effects differ across use of ICTs measured by generation, time online and prior use of participatory platforms. The results suggest that most design features have clear effects on evaluations, and that deliberative features have the strongest effects. Furthermore, the effects are relatively stable across prior use although the less experienced put a stronger emphasis on verification.  相似文献

Increasing numbers of Spanish-speaking preschool children require attention to improve the likelihood of success in school. This study, part of a larger 2-year ethnographic study of a Head Start classroom, elaborates the role of teachers’ interactions with students who were learning English. Using an interactional ethnography approach, the authors focus on the social nature of these interactions. The study illuminates the kinds of teacher interactions with students that support and hinder the students’ language learning. It reinforces the importance of student engagement in social interactions with teachers and with English other than codes of obedience and authority. Finally, it recommends actions teachers can take to provide optimal circumstances for English learning interactions for students.
