Readers' advisory databases are used by public librarians to assist patrons in finding books based on the facts of the plot, the factors used to describe the appeal of the book, or read titles similar to another book they have read. Librarians depend on these databases to give a complete view of the titles available given these limiters, and may assume that identical searches in each database would give similar results. This study compares search results from four databases to see the extent of crossover within those results, using fact-based searches, appeal factor searches, and read-alike searches. 相似文献

This study investigated how clients and advertising agencies in Korea prioritized celebrity selection criteria differently. Responses from 50 client-side and 50 agency-side executives in Korea were analyzed using the Analytic Hierarchy Process. Results show that the brand-centered factor ‘Match-up’ was considered most important by both clients and agencies but that the celebrity-centered factor ‘Popularity’ was ranked quite differently (i.e. second by agencies and fourth by clients, out of five factors). Other factors (i.e. Availability and Potential Risk) were ranked similarly. The main finding of the study is that Korean ad agencies and clients placed different weight on celebrity endorser selection criteria. This finding is particularly valuable to national and international advertisers who are deliberating about celebrity endorsement for the Korean market. 相似文献

ABSTRACTWhat happens when a human coder meets a machine one? This article explores this question with reference to the archive of Professor Germaine Greer: Australian-born feminist, performer, scholar, and professional controversialist. It does so by staging two very different data encounters with the 70,000-word finding aid for the print journalism series, a key component of Greer’s archive. The first encounter is archivist’s creation of the finding aid; the second, archivist and literary scholar’s interpretation of this archival metadata using sentiment analysis. Interrogating these activities side-by-side opens up a productive middle ground between humanities scholars and computer technicians, between historians and archivists, between the hand made and the machine made.This article argues that sentiment analysis offers a new and highly productive method of interrogating archival metadata, and that, as a method which privileges emotive understandings of content, it is particularly appropriate to the study of feminist archives like Greer’s. It also argues that these kinds of detailed finding aids are new datasets that reward analysis in their own right, and particularly when considered in dialogue with—rather than simply used as straightforward navigational tools for—the ‘original’ archival content. 相似文献

Teachers' perceptions of teacher and librarian collaboration: Instrumentation development and validation 总被引：1，自引：0，他引：1
Teacher and librarian collaboration is recommended in professional library and information science guidelines for school librarians. The guidelines suggest that when school librarians become an integral part of instruction, student learning improves. A proposed model of teacher and librarian collaboration identifies four facets of collaborative practices that are involved in teacher and librarian collaboration. The teacher and librarian collaboration model suggests that high level collaborative endeavors are most likely to have an effect on student learning. Exploratory factor analysis procedures were used to examine the structure of the Teacher and Librarian Collaboration (TLC-II) survey, an instrument developed using previously described collaborative endeavors between teachers and librarians. The analysis used responses from a sample of teachers from two school districts in the United States. Exploratory factor analysis was carried out on teacher scores (N = 194) for each of two sets of 16 questions regarding frequency of collaborative endeavors and importance to student learning. Cronbach's alpha was used to determine internal consistency reliability of the survey. Four factors emerged: Integrated Instruction, Integrated Curriculum, Coordination, and traditional cooperative roles between teacher and librarian. The factorial validity needs to be assessed with confirmatory factor analysis. 相似文献

ABSTRACT The study investigated implications of variations in EAD-encoded finding aids on the Web. A content analysis methodology was used to examine five different aspects of EAD finding aids: (1) data elements; (2) labeling terminology; (3) navigation; (4) browsing; (5) searching. Seventeen EAD finding aid web sites selected from 161 RLG member institution web sites, were examined. The results of the study showed that variations in EAD finding aids existed. These include inconsistency in the use of data elements, labeling terminology, and browsing attributes. In addition, some of the EAD finding aid web sites did not provide navigational aids within a finding aid or search functions for access to it. Findings suggest that increased navigational aids, as well as more browsing and search functions are needed to provide better access to EAD-encoded finding aids. 相似文献

Collection development in college and university libraries most often occurs using longstanding traditional selection methods, such as favorable book reviews or local user needs. This study uses citation analysis as a tool to select books for the social science book collection in one academic library and compares the circulation of books using traditional methods to those books using citation analysis. The journal impact factor was used to determine those journals and authors cited the most in the disciplines of business, anthropology, education, political science, psychology, and sociology. If those authors published books, the books were purchased and circulation data on the books were tabulated and compared to books chosen using traditional methods. Findings indicate that books purchased using traditional methods of selection circulated more, except when individual disciplines were measured. In the areas of business, political science, and psychology, there was no significant difference in circulation statistics, and together both the traditional and citation analysis methods accounted for circulation of nearly 95% of the social science collection. Since it is based on scholarly activity, citation analysis is a collection development method that could be used in all academic libraries. 相似文献

This study provides an experimental test for the conclusions of the Allen and Preiss (1997) meta‐analysis that statistical evidence is more persuasive than narrative evidence. This investigation extends that finding to consider the case where a message combines statistical and narrative evidence to determine if a combination of evidence is more effective than a single form of support. This investigation using 15 messages and 1,270 participants finds that a message combining narrative and statistical evidence is more persuasive than a message using either narrative or statistical evidence alone. 相似文献

This study is aimed at investigating information behavior of journalists in Kuwait. It attempted to seek answers to questions such as how search for information is initiated, what information sources are preferred and how successful is information finding? Journalists were asked to report critical incidences of information finding related to their recent journalistic assignment through a questionnaire. Analysis of 42 critical incidents indicated that journalistic assignments were in four major areas: political, cultural business, and sports. In most cases, background information was most frequently sought type of information. Internet was the most frequently used information source even though some journalists perceived that information available on the various websites may not be very objective. A follow up study is planned to be carried out to discuss the findings with a selected group of journalists using focus group discussions. 相似文献

Modeling Web-based library service quality 总被引：1，自引：0，他引：1
Studies of e-service quality have consistently used adaptations of service-quality measurement tools that have been adopted and extended from traditional service-quality frameworks. However, a fresh insight into the investigation of key determinants of Web-based library service quality, with an emphasis on how library customers perceive service quality, has much to offer. Key determinants were identified, and contributed to the development and empirical testing of a proposed conceptual model of service quality that encompasses environment, delivery, and outcome quality. Unlike the disconfirmation approach, the performance-only measure was used. Participants included postgraduates and academic staff from four research intensive universities in Malaysia. Exploratory factor analysis and confirmatory factor analysis using structural equation modeling was carried out in order to develop and validate a measurement model for Web-based service quality, which included three second-order dimensions and eight first-order dimensions. Insights into the conceptualization of Web-based library-service quality as a multidimensional hierarchical construct are provided. The emergence of specific determinants specific to the Web services supports the notion that measurement of electronic-service quality is different from traditional services, though they may share some common factors. 相似文献
