Academic libraries are increasingly called upon to demonstrate their value to their home institutions. Research collaboration with faculty resulting in the co-authorship of scholarly output is one possible way to demonstrate the alignment of the library with the institutional mission. Involvement in research also improves librarians' skills in offering research support services. This study explores the contribution of librarians to scholarly journals in fields other than Library and Information Science (LIS) as well as their collaboration practices with researchers in those fields. Results show an increasing number of papers published by library-affiliated authors in non-LIS journals between 2006 and 2015. The papers fall broadly into four areas: articles on topics related to LIS published in non-LIS journals; higher education and information literacy; systematic reviews and meta-analysis; and research collaboration in the faculty's areas of expertise. The study is limited by the difficulty in properly retrieving the scholarly output of librarians from bibliographic databases and the difficulty in ascertaining their contributions to published articles.  相似文献

The study is informed by the Punctuated Equilibrium Theory and the Diffusion of Innovation Theory. The integrative theoretical approach allowed for methodological pluralism and enabled the researcher to discuss two distinct types of change, namely evolutionary change and revolutionary change. Both qualitative and quantitative methodologies were employed. The qualitative methodology was dominant, while the quantitative methodology was supplementary. The study integrated case study and survey research methods within a single research design. Respondents in the case study were surveyed using survey questionnaires and in-depth interviews. The population of the study comprises all LIS faculty staff, Deans/Heads of Departments (HODs) in higher education institutions (HEIs) offering LIS education in Zimbabwe. The study found that LIS faculty members have high awareness levels and optimism about paradigm shifts in the fields of library and information science. Despite this awareness, knowledge and optimism, LIS faculty staff are victims of paradigm effects and paradigm paralysis. This suggests that for any change initiatives to succeed, LIS faculty members need to break the chains of paradigm effects and paralysis. Until the chains are broken no meaningful evolutionary or revolutionary change can happen in LIS education and training in Zimbabwe. The findings provide fundamental information for decision makers at national and institutional levels. The information can be used for the purpose of analysis, advocacy and strategic planning for educational reforms.  相似文献

One aspect of faculty effectiveness can be measured through research productivity, and publication and citation rates can serve as an indicator of that productivity. This study, the fourth in a series to examine LIS faculty and program productivity as measured by publication and citation, uses the same methodology as the previous investigations. A consistent data instrument (the Social Science Citation Index) provided publication and citation data for LIS faculty, covering the years 1999 to 2004. Tables show the faculty and programs with the highest publication and citation rates, both overall and per capita, as well as a cumulative ranking of LIS programs based on faculty research productivity. This study, in conjunction with the three previous, documents an increase in LIS research productivity, suggesting an increase in faculty effectiveness.  相似文献

The rapid developments of wireless telecommunication networks and the widespread increase of smartphone ownership around the world have created tremendous impacts on the services provided by institutions of higher education worldwide on several dimensions. Unarguably, mobile technologies have created new and unforeseen opportunities for educators, information services providers and students to experience the new horizon of teaching, learning, as well as knowledge transfer and creation. Taking into consideration that since Library and Information Science (LIS) students are training to become future LIS professionals, they are expected to be ready as well as active in integrating mobile technology into their daily learning practices.This study was set up to examine two groups of students (namely: LIS versus non-LIS students) at Peking University – their attitudes and level of activeness in adopting mobile technology in their daily life, as well as in their learning practices. Quantitative questionnaire survey was used for data collection, and a total number of 319 responses (i.e., LIS, 63 and non-LIS, 256) were collected from this study. Findings of this study reveal that no significant differences were found between the two student groups (LIS versus non-LIS) in many areas. In fact, both LIS and non-LIS student groups were using their smartphones to engage in different learning, research, social networking, pastimes, and recreational activities on similar level. However, it was concerning to note that the LIS student group was slightly less active in accessing the online services and resources provided by their university library. This was a particular finding that went against the researchers' original anticipation. However, such unexpected finding did not mean that these LIS students were necessarily less active or ‘open’ as mobile learners. For the reason that in comparison to their non-LIS counterparts, they were equally as active as in terms of using their mobile devices for other learning (particularly collaborative learning) and research purposes. Further studies are recommended to determine various factors that are hindering these LIS students from using the university library's online resources and services on a more active level.  相似文献

The information sector is a dynamic disciplinary and professional field, located in a fluid social and technological environment. The educational choices of students in library and information science (LIS) departments is an important aspect of the process through which they construct their ambitions, plans, and future capabilities, and so research on students' choices and their educational careers as social processes is also important. Through a detailed consideration of case study accounts of students from LIS departments in Greece, the argument for the importance of social and cultural factors in the formation of students' identity is advanced. Data were collected in two research phases using a questionnaire survey and semi-structured interviews. Analysis of data demonstrates the complexity of the process of making educational choices, revealing how individual, family, social, and institutional factors interrelate with the ways young people cope with contingencies, and with social and personal relations. How these complex influences facilitate or impede students' trajectories within higher education institutions is also shown, as well as how they act upon the construction of their pedagogic identities. Of considerable significance is the finding that students from lower social class backgrounds tend to form pedagogic identities that are fragile. By contrast, students from families with significant amounts of cultural and social capital are in a position to exploit the academic and social resources of institutions, and to construct embedded identities with a strong scientific basis. More research is needed to illuminate how LIS departments could develop mechanisms to reduce such discrepancies.  相似文献

This article sought to investigate the evolution of library and information science by tracking the author-supplied keywords in the research articles published in the domain between 1971 and 2015. Data was extracted from Thomson Reuters’ citation mainstream indexes and analysed using the VosViewer computer-aided software to obtain author-supplied keyword frequencies in each decade since 1971. We identified the most salient and common research themes in LIS and how the themes have evolved, by delving into the author-supplied keywords to proxy research themes in the field domain. Results indicate that the field of LIS has evolved in terms of its subject focus from information systems design and management in the 1970s to scientific communication, information storage and retrieval, information access, information and knowledge management, and user education in 2015. The application of ICTs in LIS practice and education, too, has emerged as a prominent topic in the field. These issues have the potential of shaping or have shaped the LIS curriculum in some LIS schools in the continent.  相似文献

This paper studies the correlations between peer review and citation indicators when evaluating research quality in library and information science (LIS). Forty-two LIS experts provided judgments on a 5-point scale of the quality of research published by 101 scholars; the median rankings resulting from these judgments were then correlated with h-, g- and H-index values computed using three different sources of citation data: Web of Science (WoS), Scopus and Google Scholar (GS). The two variants of the basic h-index correlated more strongly with peer judgment than did the h-index itself; citation data from Scopus was more strongly correlated with the expert judgments than was data from GS, which in turn was more strongly correlated than data from WoS; correlations from a carefully cleaned version of GS data were little different from those obtained using swiftly gathered GS data; the indices from the citation databases resulted in broadly similar rankings of the LIS academics; GS disadvantaged researchers in bibliometrics compared to the other two citation database while WoS disadvantaged researchers in the more technical aspects of information retrieval; and experts from the UK and other European countries rated UK academics with higher scores than did experts from the USA.  相似文献

Abstract

Using a scientometric approach, this study examines scholarly publications by library and information science (LIS) researchers affiliated with Iranian institutions that were published in non-Iranian journals and indexed in the Web of Science (WoS) database, together with publications in Iranian LIS journals from 1980 through 2016. The results show that Iranian authors published 538 LIS documents indexed in WoS and another 7,837 in national journals. The research article was the predominant document type at both the national and international levels. The total number of international publications in LIS by all countries was 313,449; Iran ranked 34th among the countries for publications in LIS.  相似文献

This article analyzes the knowledge structure of library and information science (LIS) in South Korea based on analysis of the theories presented in scholarly research articles. A content analysis of 654 LIS articles that appeared in two major journals since 1970 revealed overall theory use in LIS, such as growth and distribution of theory use by subfield, origin of theory, degree of theory use, and development of theory. The 654 articles analyzed used about eighty theories. The largest percentage of theories originated in LIS, followed by social science, sciences, and humanities. The degree of theory use indicates 2.10 in the 5 point ratio scale of the “Five Degrees of Theory Use Model.” The proposed theory use model provides an analytical tool to delineate degrees of theory use in LIS. In short, the results of knowledge structure analysis in LIS research show that LIS in South Korea needs much more development in various fields.  相似文献

Although creating sustainable information systems is highly important to facilitate information flow in natural disaster information management (NDIM), only a few LIS studies have focused on evaluating the feasibility of related technological solutions. An open access repository (OAR) for NDIM has been assessed by Technical, Economic, Legal, Operational, Scheduling, Cultural, and Behavioral (TELOS-CB) dimensions, using the PSI technique. Five NDIM stakeholder groups participated including governmental, public, and research institutions, NGOs (non-governmental organizations), and LIS specialists. The results indicate that the NDIM-OAR is technically more feasible, while the cultural dimension has been considered the most challenging. NGOs have the largest scoring range and governmental stakeholders have the most coherent scoring. Despite of the wide range and seemingly excessive sensitivity of NDM information in Iran, more in-depth, interpretive, cross-disciplinary studies are required reaching a comprehensive decision for an NDIM-OAR. The research is among the first multi-disaster, multi-stakeholder feasibility analyses in LIS.  相似文献

The purpose of this article is to explore the use of mixed methods research (MMR) in articles published in library and information science (LIS) journals in Sub-Saharan Africa (SSA) from 2004 to 2008. A mixed methods research framework provided in the methodological literature is used to determine how this method was practiced within the LIS scientific community in SSA. Six hundred and eighty five articles published in nine peer-reviewed LIS journals in SAA were reviewed, finding the dominant research methods in these journals to be survey designs and historical research. The use of MMR was limited: 48 out of 685 articles used the mixed methods approaches that were identified in the methodological literature. A paradigm shift and a change of mindset are recommended for LIS researchers in SSA so that they may exploit the advantages offered by mixed methods research in conducting their studies.  相似文献
