In May 2011 the Bing Search API 2.0 had become the only major international web search engine data source available for automatic offline processing for webometric research. This article describes its key features, contrasting them with previous web search data sources, and discussing implications for webometric research. Overall, it seems that large-scale quantitative web research is possible with the Bing Search API 2.0, including query splitting, but that legal issues require the redesign of webometric software to ensure that all results obtained from Bing are displayed directly to the user.  相似文献

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

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

Reductions in work force (downsizing, delayering, resizing, outplacement, layoffs, demassing) are used by organizations to achieve desired economic goals and ensure survival. However, these reductions often negatively affect the work behaviors and attitudes of continuing employees and thus, may detract from the success of the reduction in work force. The purpose of this study was to increase our understanding of the effects of multiple workforce reductions on survivors by extending Brockner's (1988) model and outlining the role of communication in the process so that researchers and practitioners can better predict and control for the effects of workforce reductions. In pursuit of this goal, a causal model of effects on survivors was developed and then tested with data collected in a large, midwestern insurance company that implemented two workforce reductions.

The hypothesized model was inconsistent with the data and subsequently was rejected. A revised model was then tested and found to fit at three time periods. The revised model demonstrates survivor reactions to reductions are complex and change over time and in response to multiple reductions. The main conclusion was that managers can influence survivor information deprivation, career future uncertainty, work satisfaction, and propensity for turnover by paying attention to, and if possible controlling, organizational identification, financial rewards, work team communication support, and manager communication support. The results also suggest that survivor reactions to prior organizational interventions may influence the success of current interventions.  相似文献
