Finding Finding Aids on the World Wide Web

Tibbo, Helen R., Meho, Lokman I. January 2001 (has links)
Reports results of a study to explore how well six popular Web search engines performed in retrieving specific electronic finding aids mounted on the World Wide Web. A random sample of online finding aids was selected and then searched using AltaVista, Excite, Fast Search, Google, Hotbot and Northern Light, employing both word and phrase searching. As of February 2000, approximately 8 percent of repositories listed at the 'Repositories of Primary Resources' Web site had mounted at least four full finding aids on the Web. The most striking finding of this study was the importance of using phrase searches whenever possible, rather than word searches. Also of significance was the fact that if a finding aid were to be found using any search engine, it was generally found in the first ten or twenty items at most. The study identifies the best performers among the six chosen search engines. Combinations of search engines often produced much better results than did the search engines individually, evidence that there may be little overlap among the top hits provided by individual engines.

Science Foresight Project

Katz, J. Sylvan, Stewart, Sally 03 1900 (has links)
The aim of the Science Foresight Project was to design and assess a simple, objective and cost-effective technique to gather information about emerging short and long-term research developments, primarily in the physical and engineering sciences. International experts were objectively chosen using co-citation patterns in scientific and technical literature, and were invited to submit their predictions about emerging developments in their research fields. They were questioned about how the effects of various factors and driving forces might affect their predictions. The cost and time required to administer the questionnaire and collect the responses was minimised through the use of Internet and Web based technologies. A simple process was used to report the predictions; short excerpts from each prediction were used as the summary and each prediction was classified into one of ten categories of emerging developments. Authors from 114 papers (23.7%) responded, identifying a total of 190 short-term and 111 long-term predicted emerging developments. Expert responses were received from an international group of senior researchers between the ages of 36 and 55, mostly engaged in basic research in academic institutions. Some experts described specific emerging developments, some discussed broad emerging trends in their field and others described both. Emerging development categories such as Atomic & Stellar Matter, Biology & Biosphere, Biomedical & Clinical, Computers & Robotics and Genomics & Proteomics were closely aligned with conventional science areas while other categories such as Mathematical & Computational and Nano Science & Technology contained predictions from almost every area of science. The technique developed and applied here appears to constitute an efficient means of surveying the international research community in order to gain insights into common patterns that evolve from their collective research activities. Dynamically monitoring emerging research developments on a continuous basis could provide valuable information to policy makers, planners and researchers.

Ranking the Research Productivity of LIS Faculty and Schools: An Evaluation of Data Sources and Research Methods

Meho, Lokman I., Spurgin, Kristina M. 10 1900 (has links)
This study evaluates the data sources and research methods used in earlier studies to rank the research productivity of Library and Information Science (LIS) faculty and schools. In doing so, the study identifies both tools and methods that generate more accurate publication count rankings as well as databases that should be taken into consideration when conducting comprehensive searches in the literature for research and curricular needs. With a list of 2,625 items published between 1982 and 2002 by 68 faculty members of 18 American Library Associationâ (ALA-) accredited LIS schools, hundreds of databases were searched. Results show that there are only 10 databases that provide significant coverage of the LIS indexed literature. Results also show that restricting the data sources to one, two, or even three databases leads to inaccurate rankings and erroneous conclusions. Because no database provides comprehensive coverage of the LIS literature, researchers must rely on a wide range of disciplinary and multidisciplinary databases for ranking and other research purposes. The study answers such questions as the following: Is the Association of Library and Information Science Educationâ s (ALISEâ s) directory of members a reliable tool to identify a complete list of faculty members at LIS schools? How many and which databases are needed in a multifile search to arrive at accurate publication count rankings? What coverage will be achieved using a certain number of databases? Which research areas are well covered by which databases? What alternative methods and tools are available to supplement gaps among databases? Did coverage performance of databases change over time? What counting method should be used when determining what and how many items each LIS faculty and school has published? The authors recommend advanced analysis of research productivity to provide a more detailed assessment of research productivity of authors and programs.

A Scientometric Method to Analyze Scientific Journals as Exemplified by the Area of Information Science

Boell, Sebastian K. 12 1900 (has links)
==Background== In most academic disciplines journals play an important role in disseminating findings of research among the disciplinary community members. Understanding a discipline's body of journals is therefore of grave importance when looking for previous research, compiling an overview of previous research and and in order to make a decision regarding the best place for publishing research results. Furthermore, based on Bradford's Law of scattering, one can assume that in order to be able to compile a satisfying overview of previous research a wide range of journals has to be scanned, but also that there are some 'core' journals which are of more importance to specific disciplines than others. ==Aim== This thesis aims to compile a comprehensive master list of journals which publish articles of relevance to Library and Information Science (LIS). A method to rank journals by their importance is introduced and some key characteristics of the disciplines body of journals are discussed. Databases indexing the disciplines journals are also compared. ==Method== The master list of LIS journals was created by combining the journal listings of secondary sources indexing the field's literature. These sources were six databases focusing on LIS literature: INFODATA, Current Contents, Library and Information Science Abstracts, Library Information Science Technology Abstracts, Information Science and Technology Abstracts, and Library Literature and Information Science, the LIS subsection in three databases with a general focus: Social Science Citation Index, Academic Search Premier, and Expanded Academic ASAP, and the listing of LIS journals from the Elektronische Zeitschriften Bibliothek. Problems related to editorial policies and technical shortcomings are discussed, before comparing: predominant publication languages, places of publication, open access, peer review, and the ISI Journal Impact Factors (JIF). Journals were also ranked by the number of occurrences in multiple databases in order to identify 'core' publications. The number of journals overlapping between databases are estimated and a matrix giving the overlap is visualized using multi dimensional scaling. Lastly, the degree of journals overlapping with other disciplines is measured. ==Results== A comprehensive master list of 1,205 journals publishing articles of relevance to LIS was compiled. The 968 active journals are mostly published in English, with one third of the journals coming from the US and another third from the UK and Germany. Nearly 16% of all journals are open access, 11% have a ISIJIF, and 42% are peer reviewed. Fifteen core journal could be identified and a list of the top fourteen journals published in Germany is introduced. Databases have between five to 318 journals in common and the journal collection shows an substantial overlap with a wide range of subjects, with the biggest journal overlap with Computing Studies, and Business and Economics. ==Conclusion== The aim of compiling a comprehensive list of LIS journal was achieved. The list will contribute to our understanding of scholarly communication within the LIS discipline and provide academics and practitioners with a better understanding of journals within the discipline. The ranking approach proved to be sufficient, showing good similarity with other studies over the last 40 years. The master list of LIS journals has also potential use to further research.

Genusvetenskapens utveckling inom B&I : en bibliometrisk studie av studentuppsatser med genusperspektiv / The development of gender studies within LIS : a bibliometric study of undergraduate dissertations with a gender perspective

Waldh, Anna-Maria January 2013 (has links)
The main purpose of this two year master´s thesis is to study patterns, structures and relations within gender studies when combined with Library and Information Science(LIS). Further aims are to determine the character of student work considering, occurrence, gender and main theme, to study the progress of the intellectual base of gender studies within LIS and to evaluate the use of bibliometrics as a tool for researching the development of a discipline. To achieve these aims, a bibliometric study using both publication analysis and citation analysis, is carried out. The studied material contains student work, specifically focused on gender, from the Swedish School of Library and Information Science (SSLIS) from 1985–2012. The results show an increasing interest in gender issues among the students and furthermore they show an interesting development of gender related themes in student work. Where students during the early years focused on female themes, the more recent years present a wider range of subjects such as gender equality, masculinity, LGBT and queer issues. The citation analysis indicates an increased interdisciplinarity within the intellectual base from 1996–2011. This is a consequence of an enhanced theoretical approach in studentwork, which leads to an increase in imported theories and methods from other disciplines. The citation analysis also reveals that the twenty most cited authors in the later years are all scholars. This is, however, not the case among the most cited authors of the earlier years where journalists and public debaters are represented. These findings correlate with Frickel and Gross’ theory of Intellectual/Scientific Movements. This study also serves as an example of how bibliometrics can be useful in examining a discipline’s structure and development

A bibliometric study of the publication patterns of South African scientists.

Jacobs, Daisy. January 1998 (has links)
One of the legacies of the apartheid system was the discrepancy in funding and support for various activities, including research work in science and technology based on racial grounds. Some institutions of higher learning and research institutes were favoured more than others in terms of resources. Presently, despite the fact that there is national democracy, previously disadvantaged institutions with their culture of minimal research and poor publication output continue to produce inadequate quantities of research and publications while the historically developed universities are at the forefront of research and publication.This research is a bibliometric study of the publication patterns of South African scientists. The subjects were academic scientists from ten selected universities of the Eastern Cape, Western Cape and KwaZulu Natal, which vary considerably, with regard to standards of education, quantity of publications, development and overall progress. The general purpose of this study was to investigate the patterns used by scientists in publishing the results of their research, provide valuable information and play a significant role in evaluating the research and publication patterns of scientists from these different institutions The study collected two sets of data through lists of publications and a questionnaire. The questionnaire was pretested and the comments of the respondents enabled the investigator to make the necessary revisions in the subsequent questionnaire. The questionnaire was sent to 350 full-time academic scientists in the departments of physics, chemistry, botany, zoology and biochemistry / microbiology in the selected universities. Out of the 350 scientists, 174 responded. Twenty one returns were discarded, hence only 153 were used in the data analysis. Further data was obtained from the Science Citation Index and the Foundation for Research Development. Data were analysed using descriptive statistics, one way ANOVA and Pearson Chi-Square test. The results obtained in this study showed that the five null hypotheses were rejected. It was found that there was a : - • direct relation between academic rank and productivity; academic status and productivity. • direct relation correlation between prestige and productivity. • higher impact of "A" grade scientists over non-"A" grade scientists. • significant difference in productivity between areas of science that are funded and areas which receive little or no funding. / Thesis (Ph.D.)-University of Natal, Pietermaritzburg, 1998.

Following the Footnotes : A Bibliometric Analysis of Citation Patterns in Literary Studies

Hammarfelt, Björn January 2012 (has links)
Hammarfelt, B. 2012. Following the Footnotes: A Bibliometric Analysis of Citation Patterns in Literary Studies. Department of ALM. Skrifter utgivna av Institutionen för ABM vid Uppsala universitet 5. 193 pp. Uppsala. ISBN 978-91-506-2279-9. This thesis provides an in-depth study of the possibilities of applying bibliometric methods to the research field of literary studies. The four articles that constitute the backbone of this thesis focus on different aspects of references and citations in literary studies: from the use of references in the text to citation patterns among 34 literature journals. The analysis covers both an Anglo-Saxon context as well as research in Swedish literary studies, and the materials used include Web of Science data, references in the Swedish literature journal TFL (Tidskrift för Litteraturvetenskap) and applications to the Swedish Research Council (Vetenskapsrådet). A study is also made of the influence of one single publication—Walter Benjamin’s Illuminations—and its impact in literary studies and in wider academia. The results from the four articles are elaborated upon using a theoretical framework that focuses on differences in the social and intellectual organization of research fields. According to these theories literary studies can be described as a fragmented, heterogenic, interdisciplinary and ‘rural’ field with a diverse audience. The fragmented and rural organization of the field is reflected in low citation frequencies as well as in the difficulties in discerning research specialities in co-citation mappings, while the analysis of the intellectual base (highly cited authors) is an example of the heterogenic and interdisciplinary character of the field, as it includes authors from many fields across the humanities and the social sciences. The thesis emphasizes that bibliometric studies of research fields in the humanities need to incorporate non-English and non-journal publications in order to produce valid and fair results. Moreover, bibliometric methods must be modified in accordance with the organization of research in a particular field, and differences in referencing practices and citation patterns ought to be considered. Consequently, it is advised that bibliometric measures for evaluating research in these fields should, if used at all, be applied with great caution. / <p>© Björn Hammarfelt 2012</p>

Open access och spridning : En kvantitativ analys av hur open access-publicerade artiklar citeras och sprids på webben / Open access and proliferation : a quantitative study of how open access published articles are cited and distributed online

Granholm, Kris January 2013 (has links)
To publish research articles by the means of open access is to provide them for free to the reader. An increasing number of universities around the world have begun to institute open access policies regarding their researchers academic output, requiring them to primarily publish in open access journals and / or archive their pre- or post- prints in institutional archives. The aim of this this thesis is to explore how the adoption of the open access policy at the Swedish Universi- ty of Agricultural Sciences in 2008 has affected how their researchers publish and if this has had any effect on how their academic output are cited and distributed online. To reach this goal a combination of bibliometric and altmetric methods were used as well as cross-referencing between Scopus, Altmetric.com, Google Scholar and the SHERPA/RoMEO database. The results points towards a mostly open access positive trend with an increase in articles published in jour- nals that allow archiving of both pre- and post-prints. There also seems to be a correlation between these journals and which kind of articles gets the most mentions in social media.
