Assessing Determinants of Perceived Ease of Use of Institutional Repositories by Lecturers in Nigerian Universities     

Alice A. Bamigbola  Airen E. Adetimirin 《International Information and Library Review》2020,52(2):95-107

Abstract

Institutional repositories (IRs) present platform to disseminate research findings to complement the traditional scholarly communication model. The use of IRs is beneficial to authors, host institutions, libraries and society at large. Despite the numerous benefits of IRs, there is low deposit of scholarly works by lecturers and the investment on IRs seems to be a waste. This study examined determinants of perceived ease of use (PEOU) of IRs by lecturers in Nigerian universities. A survey of lecturers received 857 respondents. Awareness, anchor and adjustment factors were found to be determinants of PEOU of Institutional repositories by lecturers in Nigerian Universities.  相似文献   

Awkwardness of becoming a boundary object: Mangle and materialities of reports,documentation data,and the archaeological work     

Isto Huvila 《The Information Society》2016,32(4):280-297

Information about an archaeological investigation is documented in an archaeological report, which makes it the boundary object par excellence for archaeological information work across stakeholder communities such as field archaeologists, heritage managers, and land developers. The quality of reports has been a subject of debate, and recently it has been argued that more emphasis should be placed on making primary research data at least similarly available. This study explores the changing materialities and reciprocal formation of documents and their users with the advent of digitization, and how documents form and lose their status as boundary objects in these processes. The study posits that in order to be functional, a boundary object needs to provide a disclosure that makes it accessible to cognate communities. Further, it shows how assumptions about the functioning of the human and nonhuman (material artifacts) influence the ways in which archaeologists conceptualize the preservation and archiving of archaeological information and the role and potential of different types of digital and paper-based documents. This article is based on an interview study of Swedish archaeology professionals (N = 16) with theoretical underpinnings in the notions of boundary objects, mangle of practice, and disclosure.  相似文献   

Comparing rankings of search results on the Web   总被引：1，自引：0，他引：1  

Judit Bar-Ilan   《Information processing & management》2005,41(6):1511-1519

The Web has become an information source for professional data gathering. Because of the vast amounts of information on almost all topics, one cannot systematically go over the whole set of results, and therefore must rely on the ordering of the results by the search engine. It is well known that search engines on the Web have low overlap in terms of coverage. In this study we measure how similar are the rankings of search engines on the overlapping results.We compare rankings of results for identical queries retrieved from several search engines. The method is based only on the set of URLs that appear in the answer sets of the engines being compared. For comparing the similarity of rankings of two search engines, the Spearman correlation coefficient is computed. When comparing more than two sets Kendall’s W is used. These are well-known measures and the statistical significance of the results can be computed. The methods are demonstrated on a set of 15 queries that were submitted to four large Web search engines. The findings indicate that the large public search engines on the Web employ considerably different ranking algorithms.  相似文献

Caveat emptor: Scan quality of Elsevier's digital backfile PDF collection     

《The Journal of Academic Librarianship》2023,49(4):102717

Scans of journal articles originally published in print, otherwise known as digital journal backfiles, benefit library patrons by providing near instantaneous access to important older information and full-text searchability. Digital backfiles can serve as a reliable surrogate for their corresponding print journals which could be removed from the library, freeing up space for other patron services. Both benefits are realized when the scanned articles are of sufficient clarity to replace the print versions. Several studies have analyzed small and subject-narrow sections of Elsevier's digital backfile. This article contains a scan-quality analysis from 1578 journals that contain nearly four million articles and represents a significant portion of Elsevier's entire digital journal backfile. We divided journals into three categories and five discipline-specific classifications and compared them by logistic regression for differences in scan quality. Approximately 4.2 % of the articles analyzed contained illegible text, tables, or figures. This data may inform a library's acquisition, retention and space-planning decisions that in turn will affect a patron's access to and use of electronic journal articles.  相似文献   

Work motivation,job satisfaction,work-family balance,and job commitment of library personnel in Universities in North-Central Nigeria     

《The Journal of Academic Librarianship》2023,49(4):102741

Increasingly, organizations are facing turbulent and competitive times. Hence, the need for universities to capitalize on the robustness and diversity of their employees to maximize their success by attracting and developing an engaged, healthy, and high-performing workforce through the provision of stimulating work environments that will promote work-family balance, work motivation, job satisfaction and overall job commitment. This study was designed to investigate the effects of work motivation, job satisfaction, and work-family balance on job commitment as well as work motivation and work-family balance as they affect job satisfaction of library personnel in universities in North-central Nigeria. The total enumeration technique was used to cover all the 926 library personnel in the universities in North-central Nigeria. The validated questionnaire was used to collect data on 926 library personnel out of which 842 responded. The response rate achieved was 91 %. The study found that work-family balance, work motivation and job satisfaction had significant effect on the job commitment of the respondents. Job satisfaction has the most significant effect (41 %) on job commitment. It is therefore, recommended that university administrators, library managers and most especially policy makers in the education sector should give adequate attention to work-family balance, work motivation, and job satisfaction when planning to improve job commitment of their employees. In addition, they should consider work motivation and work-family balance to improve job satisfaction of the library employees.  相似文献   

Determinants of social media information credibility among university students     

《The Journal of Academic Librarianship》2023,49(4):102745

This research explored the perceptions of university students about the credibility of information being shared on Facebook. The data were collected using an online questionnaire from university students who were Facebook users. A total of 325 usable responses were received which were analyzed using SPSS. The results revealed that these students perceive information shared on Facebook as credible and of good quality. The source credibility, medium credibility, and information quality had positive and significant relationships with each other. The age, social background, and educational level of students appeared to predict the credibility of information shared on Facebook. These results are useful for information professionals and social media managers in extent to understand and cater to the demands of information consumers. These findings would also be helpful for teachers, information providers, and researchers to understand the perspectives of developing countries' students on the credibility of social media information. Furthermore, this study is supposed to be a valuable addition in existing literature which could provide guidelines for novice researchers, interested in exploring the area, especially in the context of Facebook users in a developing country's context.  相似文献   

An addendum and correction to “Mathematical properties of Q-measures” (vol. 7, issue 3, pp. 737–745)     

《Journal of Informetrics》2014,8(3):486-490

A correction is provided for the proof of a theorem announced in (Rousseau et al., 2013). We show, moreover, that in a network subdivided into three or more subgroups there is at most one node with global Q-measure equal to one. In case there are two subgroups then it is possible to have two nodes with global Q-measure equal to one. This characterization leads to a graphical representation of networks having the maximum possible number of nodes with Q-measure equal to one.  相似文献   

Time gap analysis by the topic model-based temporal technique     

《Journal of Informetrics》2014,8(3):776-790

This study proposes a temporal analysis method to utilize heterogeneous resources such as papers, patents, and web news articles in an integrated manner. We analyzed the time gap phenomena between three resources and two academic areas by conducting text mining-based content analysis. To this end, a topic modeling technique, Latent Dirichlet Allocation (LDA) was used to estimate the optimal time gaps among three resources (papers, patents, and web news articles) in two research domains. The contributions of this study are summarized as follows: firstly, we propose a new temporal analysis method to understand the content characteristics and trends of heterogeneous multiple resources in an integrated manner. We applied it to measure the exact time intervals between academic areas by understanding the time gap phenomena. The results of temporal analysis showed that the resources of the medical field had more up-to-date property than those of the computer field, and thus prompter disclosure to the public. Secondly, we adopted a power-law exponent measurement and content analysis to evaluate the proposed method. With the proposed method, we demonstrate how to analyze heterogeneous resources more precisely and comprehensively.  相似文献
