Abstract This article presents the results of a study performed on the interlibrary loan patron request records at the library of John Jay College of Criminal Justice, an urban commuter college with a specialized curriculum. The findings suggest that the increasing availability of electronic full-text resources has had a significant impact on the volume of faculty and graduate student interlibrary loan borrowing of nonreturnable, photocopied materials. This appears to be the case across disciplines and regardless of the currency of the needed materials. The downward trend in demand for these materials may be outpacing actual full-text availability. This may suggest that content is being replaced with convenience. This could have implications for reference librarians and their role in the research process. Declining demand may also provide interlibrary loan librarians and their staff opportunities to alter their services and develop new skills. 相似文献

ACRL Library Trends and Statistics survey data from two years were analyzed to explore relationships among variables thought to predict full-text article requests. Five different regression models predicted full-text article requests from variables including reference transactions, library instruction, Web site visits, database searches, and ongoing expenditures. Full-time student enrollment and Carnegie classification were included as covariates in all five models. All regressions supported using enrollment as a covariate; four of the regressions supported using Carnegie classification as an additional covariate. Results suggested that reference transactions, library instruction, and ongoing expenditures increase the number of database searches and full-text requests beyond these covariates. Ongoing expenditures made the largest contribution in all models, but did not always contribute the most unique variance. Furthermore, a mediation analysis showed a significant indirect effect of library instruction on full-text requests through database searches. This study suggests most ACRL data may need log transformation before using regression analyses, and offers one approach to interpreting results. Future research could investigate the meaning of ongoing expenditures after controlling for institutional size and Carnegie classification. Additional variables such as interlibrary loan usage or whether the library has a discovery tool might be interesting to include in similar models. 相似文献

Colleagues helping each other to publish in medical sciences: Iranian field specialists' convenience editing strategies 
下载免费PDF全文
下载免费PDF全文 This article reports a study into 60 research articles (RAs) authored by Iranian medical researchers and published in high‐quality international English journals. It investigated how academic professionals in medical sciences implement peer convenience editing (CE) to improve articles and make them suitable for publication. The research identified nine editing interventions that were categorized as micro‐ or macro‐editing strategies. The findings indicated that the most frequently used strategies are micro‐strategies of substitution, addition, and mechanical alteration. The study also found that the abstract received the majority of editorial changes (mostly micro), followed by the introduction and then the discussion sections. The findings may help authors and institutions identify which sections and which types of editorial interventions are most likely to be required to ensure that RAs are optimized for publishing in international journals. 相似文献

The research community is working to create new capabilities to share data and to deal with issues of data quality, standards, and protection, and ethical and responsible use of shared data. These issues have been found to influence the willingness of researchers to publish data created during the course of their research. We use the results of a survey conducted by the working groups of the DataONE project to present a new understanding of challenges to the development of global data collections and preservation by systematically examining the determinants of the researchers' likelihood to openly publish research data. This study found two key determinants affecting researchers' willingness to publish their data. First is data management in terms of data management skills and organization support. Second is the acknowledgement of the data set's originator in terms of appreciation and legal and policy requirements. This study also found that the impact of the significant determinants is contingent on the amount of data to be published. Finally, this study calls for further investigation to ascertain the relationship of data management and data quality, and systematic investigation on the roles and responsibility of government within these global data preservations. 相似文献

One of the most important issues facing scholarly communication today is what constitutes quality in the publishing and dissemination of research findings; the aim of this exploratory research study was to investigate author‐perceived quality characteristics of science, technology and medicine journals. We triangulated data from a small number of volunteer full‐time faculty members of Long Island University, using three different research techniques: (1) questionnaire survey, (2) focus groups, and (3) semi‐structured face‐to‐face interviews. The study identified some significant differences by discipline, gender, and tenure status. Overall, the three most important attributes were the reputation of the journal, the estimated length of time to article publication, and the readership of the journal. Our findings bring new insight into this area for the scholarly research community as a whole. 相似文献

The advent of the electronic library and associated information technology (IT) assisted communication and organization of information, has implications for information-seeking and research in academia. This article, while indicating emerging findings, primarily discusses methodological issues arising from the evaluation of the impact of IT-assisted information systems. Five key issues are outlined: (1) incomplete knowledge of the operating variables in this new area, (2) the complexity of the information-seeking process, (3) the largely implicit nature of research and information skills, (4) the difficulty of detecting impact of new systems on research activity, and (5) the difficulty of explaining learning and take-up of IT-assisted information systems. These issues have required the development of creative research solutions within a framework which includes the following: holistic, inductive research; a fluid, developing methodology; the use of both idiographic and nomothetic approaches; collection of data on behavior, cognitions, and emotions; techniques to bring implicit knowledge into conscious awareness, such as information access stories and research timelines; and the analysis of both research outcome and process and the investigation of strategies for learning how to use systems. 相似文献

The number of publications and the number of citations received have become the most common indicators of scholarly success. In this context, scientific writing increasingly plays an important role in scholars’ scientific careers. To understand the relationship between scientific writing and scientific impact, this paper selected 12 variables of linguistic complexity as a proxy for depicting scientific writing. We then analyzed these features from 36,400 full-text Biology articles and 1,797 full-text Psychology articles. These features were compared to the scientific impact of articles, grouped into high, medium, and low categories. The results suggested no practical significant relationship between linguistic complexity and citation strata in either discipline. This suggests that textual complexity plays little role in scientific impact in our data sets. 相似文献

Citation Behavior of Advanced Undergraduate Students in the Social Sciences: A Mixed-Method Approach
Ilka Datig 《Behavioral & Social Sciences Librarian》2013,32(2):64-80
ABSTRACTCitation analysis is a popular research method in library science, often used to evaluate collections and instructional services. There are multiple advantages to combining citation analysis with qualitative research methods. This article describes a study in which Capstone projects by graduating undergraduate students in the social sciences were examined using both citation analysis and focus groups. The goal of this research was to gain a greater understanding of the types of sources used by advanced undergraduates in the social sciences, the library-provided availability of those sources, and a sense of how these students find, evaluate, and select sources for their Capstone projects. Notable findings include the heavy reliance of students on journal articles and the large influence of professors and other mentors on students' citation behavior. 相似文献

This article provides a brief history of the development of the MEDLINE database and its huge impact within the UK, from its inception to the present time. The origins of MEDLINE can be traced back to a collection of books in the US Surgeon General's Office during the American Civil War and John Shaw Billings' decision, during 1867, to make this Library as complete as possible. From these beginnings, Index Medicus was developed in the early years of the 20th century, and electronic versions of the database began with the computerized on-demand search service MEDLARS in 1964 and then via CD-ROM and Internet Grateful Med to the web-based and free-to-all service, PubMed, in 1997. The response to PubMed was immediate and startling with usage increasing from 7 million searches per annum in 1996 to 400 million searches per annum in 2001 and the service continues to improve. MEDLINE providers are now offering mapping of natural language queries to the sophisticated indexing vocabulary (Medical Subject Headings, MeSH) and the provision of specific filters for different types of publication to improve searching efficiency, as well as links to full-text versions of the papers where available. The next steps are likely to involve an increased blurring of database and full-text boundaries, incorporating seamless access to the best available evidence within MEDLINE and a wide range of other information resources within a single search and to an increasing amount of full-text via various open-archive initiatives. As ever, the US National Library of Medicine is in the vanguard of research and further applications of its MEDLINE database for users within the UK will be awaited with great interest. 相似文献

Television programs' production value is highly regarded by professionals as a crucial dimension of program quality. This study examines the degree to which lay viewers, rather than professionals, are sensitive to television programs' production value as a distinct evaluative dimension, their ability to pass educated judgments on production value, and the impact of these judgments on their overall program appreciation and quality assessment. Based on a large-scale survey of television viewers in Israel, we find that production value makes up a distinct evaluative dimension, indicating that viewers are sensitive to production considerations. Production value assessments also explain television program appreciation and quality evaluations. On the other hand, there are indications that lay viewers are not very good at discerning gradations of production value among different programs and genres. These findings are discussed in the context of the conflicting interests among Israeli program makers and television channel franchisers to cut costs or to invest in the quality and production value of domestically produced programs. Based on the findings, a deliberative procedure is suggested which can accommodate these conflicting interests by combining lay viewers’ quality assessments with professionals’ more considered and informed judgments. 相似文献

There has been a longstanding debate about the merits of collaborative research, with most studies focusing on the citation advantage of such research. However, citation studies provide only one lens on the issues. New methods of inquiry are necessary to incorporate other audiences of scholarly literature. Reader response surveys were used to evaluate the quality of collaborative versus single-authored research. Graduate students in three sections of the same library and information science course during the 2010 academic year used surveys to rate each week's assigned readings according to overall quality, usefulness for class discussion, and enjoyability. Students voted whether to keep each article in the reading list for the following semester. Data were analyzed to compare results for single-author versus multi-author works. Multi-author works were favored over single-author. These findings provide another layer of empirical support for the benefits of collaborative research and inform both scientometricians and educators. 相似文献

Traditionally, librarians take a role in connecting researchers with resources. With the advent of the digital age, the nature of research is expanding; there are more, and different, sources of data, ways of collecting data, and methods of analyzing and interacting with data. If librarians are to remain relevant and able to serve their patrons, then they must engage in research as guides or even as partners in the research process. To do this, it is critical that librarians gain an understanding of the nature of research in the digital age and of the frameworks, methodologies, and issues related to digital research. The purpose of this article is to contribute to literature on digital research as it relates to librarianship. 相似文献

Amateur photographs must fulfill specific standards if they are to be used in professional news media. These standards include news value, credibility, ethics and taste, as well as the technical and aesthetic quality of images. The research presented in this article explores the value of poor-quality photographs for the news industry, and the view that they can be good enough for certain news content. At the same time, this article reveals strong reservations regarding the incorporation of amateur photographs. The article asks whether such findings manifest necessary quality standards, or whether they constitute claims to defend the position of the professional news media. The data for this article were collected in 2010/2011 using observation, interviews and textual analysis. 相似文献

Morality plays an integral role in perceiving and judging fictional characters since liking morally good characters leads to a general enjoyment of the narrative if the outcomes of actions are favorable for the liked character. However, some fictional characters frequently violate moral standards but are still popular at the same time. To explain this paradox, the present study offers a two-process model on the appeal of morally ambiguous characters, proposing psychological mechanisms leading to either enjoyment or appreciation. These mechanisms were tested based on an online survey (N = 429) examining four different television series which featured morally ambiguous protagonists. Findings largely supported the notion that while liking the character leads to enjoyment, social comparison processes (based on moral principles) were associated with appreciation. This study extends findings of previous investigations by offering a more comprehensive understanding of how morally complex narratives can lead to entertainment experiences. 相似文献

This article summarizes the author's dissertation regarding search strategies of millennial undergraduate students in Web and library online information retrieval systems. Millennials bring a unique set of search characteristics and strategies to their research since they have never known a world without the Web. Through the use of search engines, they have come to expect that searches can be completed using an easy, single search box that produces complete articles on just about any topic. However, the reliability and quality of much of the information on the Web is questionable. Conversely, information that resides in library information retrieval systems is often of high scholarly content, but there is not a single, user-friendly system for millennials to use. A case study investigation was conducted at the State University of New York at Oswego, a public undergraduate university in Central New York. The goal of the study was to identify the search strategies of a sampling of millennial undergraduate students in both Web information retrieval systems and library information retrieval systems in order to expand upon existing theories about millennials and to suggest interface design enhancements, which could make online library information retrieval systems easier for millennials to use. The findings recommend improving database search functionality, such as natural-language searching, spell-checking, and uniform full-text wording and placement. Results also suggested that increasing the availability of full-text articles would contribute to millennials’ use of library information retrieval systems. 相似文献
