Higher education institutions are increasingly exploring how they can use emerging technologies to develop and enhance the learning experiences offered to students. These activities have mainly focused on developing student‐centred facilities. The University of Warwick has taken the next step by developing a space (the Teaching Grid) specifically designed to meet the needs of teaching staff across the institution. This paper describes how the Teaching Grid supports teachers by providing a flexible experimental space together with a rich collection of established and new technologies, and with comprehensive staff support. We analysed the use of the facility during the first 30 months of operation, using data collected from 119 case studies, in order to present a perspective on how they have used the technologies and how this has impacted on their teaching practice. We present a taxonomy that provides a concrete framework to support future analysis of and comparisons between such spaces.  相似文献

Using empirical measures, a pilot test of an investment model of commitment to television news quality yielded statistically significant results supporting four hypothesized relationships between types of broadcast station ownership. The findings indicate that the news department operated by a small media group produced more local news, more locally produced video, more use of on-air reporters, and fewer news promotions than the larger chain-based broadcast groups investigated, suggesting a deeper commitment to local news quality. The results support the policy position that stricter ownership limits would enhance the quality of local television news.  相似文献

The advent of radio broadcasting brought some significant changes into presidential campaigns but it jailed to produce other changes that one might have expected to arise from the use of this new communications medium. This paper describes the changes that took place and examines the reasons for certain expected changes failing to materialize.  相似文献

Western police forces have always been institutions powered principally by the efficient accumulation of information, from the oral histories that defined the earliest foot patrols, to the communicative velocity of modern mobile data terminals. As these technologies evolve, however, the more the police devolve to become a data mining entity in earnest. This article interrogates the genealogy of a disciplinary nomenclature the author coins hegemonic shorthand—a formulaic meta-language grounded in a culture of standardization and interpolation among the police that flourishes in paranoid times under the pretense of public protection.  相似文献

Research demonstrates that methamphetamine is a serious problem in gay communities. This study examined the framing of methamphetamine in nine gay, lesbian, bisexual, and transgender (GLBT) newspapers. Results showed that methamphetamine was framed as a “gay problem,” that sexual health and solutions frames were prevalent, and that GLBT newspapers covered methamphetamine in a way that is similar to how they covered AIDS in the 1980s. Implications for health campaigns are discussed.  相似文献
