    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

    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

    Dispelling the Myths Behind First-author Citation Counts

    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

    A Cooperative Model for Preserving Historical Television News Content

    Get PDF
    The archival profession must begin to confront the many challenges inherent in the large-scale preservation of twentieth century audio/visual resources. A significant portion of our shared cultural heritage, including historical television news recordings, is at risk due to complicated copyright issues, degradation of the original media, the cost involved in digitizing audio/visual resources, and the difficulty of preserving high resolution digital video files. Cooperation between heritage institutions and content creators facilitated by a Custodial Partnership Model is the key to overcoming these significant challenges. The University of North Texas (UNT) and the Dallas/Fort Worth (Texas) affiliate station of the National Broadcasting Company (NBC 5/KXAS) have partnered to preserve the content of the oldest television news station in Texas. This unique partnership will not only preserve over 60 years of television news content through the digitization of original 16mm film and video, but it will also result in free public access to the digitized content online. This paper will explain this partnership from the perspective of both the library and the television news station, and it will provide s possible solutions to the issues of copyright, funding and access to audio/visual collections. Examples from the UNT-NBC 5/KXAS partnership will serve to illustrate the crucial need to preserve audio/visual collections and the challenges facing institutions preserving large scale audio/visual collections. Lastly, this paper introduces the Custodial Partnership Model, a new paradigm for future heritage institution/content creator partnerships and recommendations for future modes of cooperation
