Five ratios RH, RT, SH, ST and SZ derived from the three-part division of a set of sources in h-core, h-tail and uncited sources are defined. Dynamic changes in the three independent ratios RH, SH and SZ are studied for six selected topics. Data about these topics are obtained from the Web of Science for scientific papers and Derwent Innovations Index for technical patents. It is observed that all RH- and SH-values decrease when the time span widens, while SZ stays the same or increases; and that all RH- and SH-values for papers are larger than the corresponding values for patents. The shifted Lotka distribution is used in a theoretical interpretation of these empirical phenomena.  相似文献

This article describes the first half century of the Communist government’s supervision and management of the central-government archives of the last two dynasties. Immediately with the Communist ascent to power in 1949, the new government took great interest in assembling and protecting the country’s archival documents, readying the Ming-Qing archives for access to scholars, and preparing for publication of selected materials. By the 1980s Beijing’s Number One Historical Archives, in charge of the largest holding of Ming-Qing documents, had become the first Chinese authority to complete a full sorting and preliminary catalogues for such a collection. Moreover, to facilitate searches, an attempt has recently begun to create a subject-heading system for these and other holdings in the country. In the first half century’s final decades, foreign researchers were admitted for the first time and tours and international exchanges began to take place.

A series of studies report the development of empirically derived instruments that measure student interest and engagement. The first study inductively develops an initial item pool through open-ended questionnaire data. A second study subjects the measures to exploratory factor analysis to ascertain an underlying factor structure. The third study deductively tests the measures through confirmatory factor analysis and examines associations among teacher communication behaviors, student emotional and cognitive interest, and engagement. A fourth study offers discriminant validity evidence, suggesting that the new measures are distinct from scales that assess similar yet divergent constructs. Guided by prior theory (Mottet, Frymier, & Beebe, 2006 Mottet, T. P., Frymier, A. B. and Beebe, S. A. 2006. “Theorizing about instructional communication”. In Handbook of instructional communication, Edited by: Mottet, T. P., Richmond, V. P. and McCroskey, J. C. 255282. Boston, MA: Pearson.  [Google Scholar]) and research (Harp & Mayer, 1997 Harp, S.

Journal of Educational Psychology, 89: 92102. [Crossref], [Web of Science ®] [Google Scholar]), the instruments developed here possess heuristic potential for instructional communication research. Implications and areas for future research are discussed.  相似文献

This article analyses the extent to which archival exemptions for historical, scientific and statistical research in privacy legislation support preservation in selected European Union countries, and comparable aspects of Australian, American and Canadian law within a legal, ethical and digital archival perspective. The authors recommend that the further processing of personal data under data protection law be given a wider scope of interpretation for archival preservation purposes in both the public and private sector, coupled with the use of researcher and archival codes in relation to access to personal data. They also recommend early appraisal and integration of privacy with freedom of information and archival regimes.

This paper reviews the archival process at the Inter-university Consortium for Political and Social Research (ICPSR), a repository of digital social science data, and maps ICPSR’s Ingest and Access operations to the Open Archival Information System (OAIS) Reference Model. The paper also assesses ICPSR’s conformance with the archival responsibilities of “trusted” OAIS repositories, with the proviso that audit criteria for archival certification are still under development. The ICPSR to OAIS mapping exercise has benefits for the larger social science archiving community because it provides an interpretation of the reference model in the quantitative social science environment and points to preservation-related issues that may be salient for other social science archives. Building on the archives’ long tradition of shared norms and cooperation, we may ultimately be able to design a federated system of trusted social science repositories that provides access to the global heritage.

Conclusion  Convergence is a very exciting model and one that holds, unforeseen opportunities. However in the current economic environment, the investment community is hesitant to recommend that communications companies devote many resources in that area. The convergence mode must prove that it can generate revenue and profits. Yet, it is limited to an advertising-supported model—a part of the communications industry that has struggled during the past, year due to the recession. The increased advertising revenue that would be generated by the convergence model is tainted—most likely taking advertising share away from the traditional media segments that are supporting the model. Tied to the convergence model is a high dependency on the Internet. Internet advertising is not local. In addition, financial data clearly illustrates that the Internet has caused profit margins to decrease substantially, something that the traditional media company supporting the convergence model can not allow to happen. Finally, FCC deregulation with regards to television station cap restrictions, cable system operators owning broadcasters in the same market, and cross ownership of newspapers and television stations in the same market, will most likely have a negative impact on the convergence model. If a communications company should decide to go forward with convergence, there are five rules that should be followed:
1.  Use personnel and technology efficiently
2.  Extend brand awareness of pre-existing communications products
3.  Offer cross-media advertising packages
4.  Return users to traditional media outlets
5.  BE PROFITABLE QUICKLY!39.
The essay is based on a presentation made by Dr. Kivijarv at convergece: The Tour, a four-day conference sponsored by The American Press Institute. The purpose of the conference is to analyze the various issues that communications companies should consider before attempting to build multimedia news operations that consolidate newspaper, television, wired cable, and/or Internet divisions in a specific market. Dr. Kivijarv's presentation occurred on the final day of the conference and spoke to the investment community's financial concerns. Veronis Suhler Stevenson publishes, two of the leading annual reports on the communications industry—the Communications Industry Forecast and the Communications Industry Report. A majority of the data used in the presentation and this essay come from those reports and Dr. Kivijarv, as the Director of Research & Publications at Veronis Suhler Stevenson, serves as the editor of the two reports.  相似文献
