Cicero recognized the benefits that a forensic orator could receive from a cooperative study of rhetoric and philosophy. This work isolates and examines two aspects of philosophy—dialectic and ethics —that were particularly important to the courts of the Republic. 相似文献

In the digital era, information literacy skills enable users to locate and use online materials effectively. One persistent library service for libraries is providing skills training to students. This article traces the creation of online library instructional tutorials, currently referred to as digital learning objects, in academic libraries. It isolates the factors that improve the success of these learning tools, including knowledge of the tutorials’ purpose and potential, collaboration with other individuals, the use of standards, student engagement, and evaluation. The literature review also illustrates the incorporation of multimedia learning theories and assessment strategies in these tutorials. By developing appropriate learning tools, librarians offer services aimed at meeting user needs while reducing time and resource demands on library staff. 相似文献

The classification of science into disciplines is at the heart of bibliometric analyses. While most classifications systems are implemented at the journal level, their accuracy has been questioned, and paper-level classifications have been considered by many to be more precise. However, few studies investigated the difference between journal and the paper classification systems. This study addresses this gap by comparing the journal- and paper-level classifications for the same set of papers and journals. This isolates the effects of classification precision (i.e., journal- or paper-level) to reveal the extent of paper misclassification. Results show almost half of papers could be misclassified in journal classification systems. Given their importance in the construction and analysis of bibliometric indicators, more attention should be given to the robustness and accuracy of these disciplinary classifications schemes. 相似文献

This paper aims the Benin Library and Information Science (LIS) professionals’ access to individuals on the social network through the study of the structure and use of the network. Subscribers to the library association’s listserv participated in a web-based survey to identify the colleagues they could easily reach. The analysis uses social network techniques and Pajek, a social network analysis software, and focuses on centralities, prestige and sub-groups to identify the key actors required for effective information sharing within the network.The density of this is very low and suggests that intermediaries are important for the connectedness of subscribers (also referred to as actors); network centralisation is moderate and explains that some actors are central for communication among the subscribers. About 60% of the subscribers fall within one of two groups. In the first group, six subscribers are central to the network, because they are moderators of the listserv, members of the association board, or well-connected to other well-connected actors. The others fall within the isolates or had few connections. 相似文献

In recent decades a distinctive literature has accumulated discussing the role of gender, feminism, and women's studies‐related research (GFWS) in the communication field; however, questions have persisted about how this research is represented in the field's publications. Contributing to the literature on the sociology of the field's scholarship, the history of the GFWS literature was sketched in a field test of a concept mapping technique that tracks patterns of publication and isolates conceptual associations within the titles of GFWS articles. The data for the study were significant concepts extracted from titles of 31,500 articles appearing in 70 communication journals and annuals within the period 1970 to 1997. The study accomplished several goals. First, it examined the accuracy of historical arguments about GFWS scholarship, arguments that bear on the issue of fair treatment of GFWS scholarship within the field. Second, it examined GFWS articles by publication source to assess patterns of representation by journal. Third, it provided a response to requests by some scholars working in the area for a thorough survey of the dimensions of the GFWS literature. Findings support the idea that GFWS scholarship is represented by a unique constellation of conceptual relationships. Feminist scholarship is found to have a history unto itself separate from that of studies of gender or sex differences, and has entered the literature in two distinctive eras. As well, feminist research was found to have a unique and uneven pattern of representation in the field's literature. By identifying threads of theoretical connection between articles in a widely dispersed literature, the concept mapping methodology is argued to provide one means for offsetting the fragmentation of the discipline's scholarship that has occurred throughout the last three decades as a result of the rapid proliferation of new specialized communication journals. 相似文献

In January 2008, Dr. Robert Hauptman, Editor, Journal of Information Ethics, and Professor Emeritus, St. Cloud University, sat down with Elizabeth Buchanan, from the University of Wisconsin-Milwaukee School of Information Studies' Center for Information Policy Research, to talk about the field of information ethics, its major issues, and the state of librarianship. As is widely known, Robert Hauptman, the author of hundreds of articles, is considered one of the founders of the field of information ethics. The formal application of ethical theory to information is termed “information ethics,” concurrently coined such by Robert Hauptman in the United States and Dr. Rafael Capurro in Germany in the mid 1980s. Laying the groundwork for the discipline of information ethics, was Hauptman's 1976 experiment. This was a seminal moment in reference, information ethics, and professional ethics, a moment to which information professionals, today, in the age of the Patriot Act, mass surveillance, and mass privacy violations, consider instrumental in understanding privacy, responsibility, and professional duties. This interview provides some insights on information ethics past, present, and future, from this transcendent scholar. 相似文献
