    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    Full text link
    We 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

    Content analysis of medical college library websites in Pakistan indicates necessary improvements

    Background: Library websites are important for marketing library services and providing access to electronic resources.Objectives: To determine the extent and quality of medical college (school) library websites in Pakistan, according to predetermined criteria.Methods: A checklist of 40 items was developed from the literature on academic library website evaluation as well as observation of known best practice. The checklist was used on the 45 medical college websites that fitted initial inclusion criteria.Results: Of the possible 114 candidates for inclusion, 52 institution websites contained no information about the library, 17 only provided minimum details, leaving 45 medical college library websites that could be included. Library websites lack uniformity, and most of the important features as only three library websites contained more than 20 items from the checklist. The Agha Khan University Medical College, Karachi library website contained the highest (27) number of items.Discussion: The findings indicate the design of medical college library websites is generally inadequate in Pakistan. The websites are not performing a useful role in communicating with faculty and students. The findings point to inadequate website design skills among librarians or the lack of co-operation with professional website designers.Conclusions: Marketing of library services and good customer relations demand improvements in the information architecture of medical college library websites as well as continued maintenance of the content to ensure that it is up to date

    Pakistan Library and Information Council

    The aim of this chapter was to propose a Pakistan Library and Information Council (PLIC) to regulate the LIS profession and to draft the Act of the proposed PLIC. Acts of councils of other professions in Pakistan were studied for this purpose. Websites of ALA, CILIP, and ALIA were also consulted to get the idea of the working of professional bodies in the field of LIS. The proposed PLIC will be a statutory professional body set up under an Act of parliament. It will register the professionals and will establish code of conduct for their members. The council will be responsible for accreditation of professional training institutions. It will also devise and maintain standards for the professional organizations. A draft of Act of proposed PLIC is presented as an Appendix to this study for suggestions from LIS experts. It is recommended that a Committee may be formulated to review the draft before presenting it to the competent authorities.</jats:p

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We 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
