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
LIBRARY NETWORKS AND CONSORTIA IN INDIA
No full textThe modern communication technologies have become essential for libraries and information centers for resource sharing in recent time. It is all due to that libraries are transforming them selve to information centers as well as to knowledge centre. The ICT is used by libraries to automation, to use for access and dissemination of information to users. Networks of libraries promotes to resources sharing, usage of library collection, problem solving of and delivery of information. The joint efforts of libraries can minimize the problem of duplications of collections. The best example is set by the Research Library Group (RLG) was founded in 1974 jointly by Columbia University, Harvard University, Yale University and New York Public Library. It is a libraries corporation in which some universities and research institutions participate in its information resource management programmes. The group adopted Bibliographic Automation of Large Library Operations using a Time Sharing System (BALLOTS) of Stanford University. The RLIN (Research Libraries Information Network) system was base on RLG"s four principal programmes – Collection Management and Development; Shared Resources; Preservation and 2 Technical Service and Bibliographic Control. The primary goal of the institutions in RLG was to inform RLG"s programmes and services to its members, to build a shared on-line database of their library collections, and cooperation in the acquisition, delivery, and preservation of information. In June 2006, RLG merged with OCLC. Its catalog became part of OCLC"s WorldCat. Eureka databases were migrated to OCLC"s FirstSearch service. By networking of libraries and information centers, modern communication technologies play a dominant role in the operation of resource sharing systems and consortia. It can be through Use of computer and communication network for resource sharing, Use of National, International databases through communication networks and Introduction of full-text CD based Systems through Article Delivery over Networked Information System (ADONIS)
