A scientometric analysis of publications on Accelerator-based research from Nuclear Science Centre and Tata Institute of Fundamental Research, India
No full textThe study is based on the journal publications generated by the Nuclear Science Centre (NSC) [now known as Inter University Accelerator Centre] and the Accelerator Group at the Tata Institute of Fundamental Research (TIFR) during 1997-1999. The data was collected from the annual reports of the two institutions and analyzed using scientometric tools and techniques. The impact was examined with the help of Science Citation Index (SCI). The analysis highlights yearly output, publication in national or international journals, number of papers in SCI-journals and non-SCI journals, normalized impact factor (NIF) per paper, category-wise distribution of papers in different NIF ranges, the proportion of high NIF papers, papers above the average NIF. NSC is a facility exclusive for accelerator research and its Annual Report gives clear indication of the different specializations, hence the data for NSC is further analyzed in three subdivisions of nuclear physics, materials science, and radiation biology and others. However, such an analysis for TIFR was not attempted due to the lack of such information in its Annual
Report. From the study one can have an idea about the performance and impact of the research conducted in the two institutions
Archiving scientific literature : an experience with e-prints archive software
No full textThe world of academic publishing is undergoing many changes. Paper based publishing is being supplemented by electronic archives. In certain areas, preprint distribution has completely moved away from the paper-based system in to a fully electronic system called eprints, based on open archives. Arxiv.org, hosted by Los Alamos National Laboratory, is considered the premier example of such e-print archives in the area of physics research. The Open Archive Initiative (OAI) develops and promotes interoperability solutions that facilitate the efficient dissemination of contents amongst the different e-print archives. The e-prints or electronic pre-prints provide an almost wholly automated and highly efficient organizational framework and distribution mechanism, which is web based. E-print software, developed by the electronic and Computer Science Department at the University of Southampton (http://www.eprints.org) is one such tool, which helps us to build e-prints archive. In this paper, we have discussed the implementation of this software by archiving couple of papers published in the Journal of Indian Institute of Science
Library networks, consortia and the changing role of information professionals
No full textLibraries all over the world have seen remarkable changes due to the influx of new technology. The arrival of Electronic books and journals has made it mandatory for the information professionals to purchase their resources through consortia and it has become a very important feature of the academic library scene. Information professionals working in libraries have to gain experiences with new modes of delivering contents and the new genre of digital collections. We need concerted efforts in consortia building, electronic licensing, staff reduction as well as investments in staffs education and development so that users of the system have the access to much more content for the same funding. Attempts have been made here to examine the additional skills required for librarians and other traditional information professionals in managing new information environment specially as information system administrator or e-resources/ consortia manager
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
Digital library development : major issues of externally published contents
No full textA library may procure contents in various sources and forms to service their clients. In the predominantly paper based erstwhile environment all these contents were put to
similar types of use, and copyright restrictions were imposed based on the quantum of pages copied etc. In the electronic and digital perspective, owners of information are resorting to punitive measures regarding the use and contents in digital form. Some of the constraints faced by our libraries to engage in serious digital initiatives are three fold that of money, manpower and contents. Most of our libraries, particularly in the higher
education and research institutes solely depend on the information providers and publishers in the developed world to satisfy their urge for vital contents that inspire
indigenous research. Since contents are a major ingredient in digital library development, the pragmatic and viable way out for libraries is to judiciously judge them
as available in electronic forms in optical media or on Web and procure at least some of them for hosting locally. This paper presents some of the major issues involved in such a critical activity with some illustrative examples available like IEE/IEEE Electronic Library, Indian Standards on CD-ROM, Science Direct and Web access of Indian Academy of Sciences journals. The justification for selecting external contents has also been mentioned. A detailed checklist for evaluating contents is presented from various angles, like authenticity of content, user interface, search and display capabilities,
documentation and technical support, and Media dependent features
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
