How Do We Measure Use of Scientific Journals? A Note on Research Methodologies
No full textScientific journals represent a significant and growing part of the libraries and many researchers have attempted to measure their use by various methodological approaches till date. In this paper, the author reviews the methodologies employed by researchers working on scientific journals usage. It aims to present an overall picture of the research methods used in the area, in a way that will be of value to anyone seeking to study scientific journals. The author reviews four main research methodologies which are being used for profiling scientific journals usage including questionnaire, interview, citation analysis and transaction log analysis
Trends in Preserving Scholarly Electronic Journals
Get PDFScholarly electronic journals have become the largest and fastest growing
segment of digital collections for most libraries. Many issues and concerns for
managing electronic journals relate to preserving and providing continued
access to them. The preserving of scholarly electronic journals is a complex
issue with various aspects and is largely different from archiving of print-based
scholarly journals. In this paper the author deals with issues concerning
archiving of scholarly electronic journals. The purpose of this paper is to
identify and discuss different issues related to preserving scholarly electronic
journals. The following issues are discussed: differences between print and
digital media, shift in the responsibility of archiving, copyright and intellectual
property rights, cost of archiving, expertise, selection, redundancy,
organizational issues, etc. Technical issues and challenges related to digital
preservation include a lack of practical implementations of preservation
standards and a lack of technical knowledge, in general, of what information is
required to support the digital preservation process within organizations.
Nevertheless, digital preservation has received considerably more prominence
in recent years, gaining the attention of entities such as national libraries,
national archives and other organizations
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
The Importance of Aggregators for Libraries in the Digital Era
Get PDFAggregators are one of the important content providers for libraries. Libraries have been working with publishers and aggregators for many years; however, the issues related to aggregators are not well documented. Aggregators have been helping libraries to facilitate their services to users but they have some disadvantages for libraries such as the lack of library influence in selecting individual titles; the lack of control over the contents of aggregator packages and the confusion of library users when accessing different packages. This paper defines different types of aggregators and discusses their importance for libraries in the digital era. The paper provides a useful overview to researchers in any field, enabling them quickly to achieve a clear picture of aggregators in the electronic environment
