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
Doing good business and quality journalism? Entrepreneurial journalism and the debates on the future of news media
As journalism finds itself in a process of accelerated transformations, Internet seems to be a place where both the reproduction of traditional models and a wide array of journalistic and business models experimentations happen at the same time. Here, at the intersection of changes in news models, job definitions and in career trajectories, the figure of the “entrepreneurial journalist” (BRIGGS, 2011) resurfaced and gradually gained in popularity over the last years in discourses celebrating innovation, flexibility and risk-taking. In this context, how can the figures of the journalist and the entrepreneur co-exist whereas commercial and journalistic activities have been historically strongly separated? How can business development be compatible with independent and objective news gathering when it is done by the same person? How do the notions of independent news writing and respect for the public interest – all strong elements of the journalistic ethics discourses – are negotiated by these actors? In this paper, we wish to explore these issues, first by contextualizing the rise of entrepreneurial journalism before presenting findings of an exploratory study about the ways the links between entrepreneurial and journalistic imperatives have been thought and presented in the existing journalistic literature in France and United States of America.</jats:p
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
«Du solide et du concret»: concentration de la propriété et convergence journalistique au sein du groupe Quebecor Média
Different merger and acquisition strategies by Quebecor Media—both vertical and horizontal integration in the news sector, followed in the 90s by a diversification of the group’s media ownership in the Web and television sectors—have led to the implementation of convergence policies for content and journalistic labour in and between each of the chains owned by the conglomerate in Quebec and the rest of Canada, with at the heart of this strategy the Web portal Canoe. These strategies are at their most advanced in the news chain Sun Corporation where in 2009 Quebecor created its own newswire (QMI) and rationalized its coverage of events by journalists. </jats:p
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
