Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Métaphores de la lutte : variations dans les corpus francophones
No full textThe aim of this study is to analyze the various discursive manifestations of the
conceptual metaphor X IS WAR within media and institutional discourse in three French speaking areas, using the Sketch Engine textometric analysis platform. Numerous studies, starting with the founding work of Lakoff and Johnson (1980) have
highlighted the weight of conventional metaphor in argumentation techniques
and the orientation of public opinion; numerous debates have also highlighted
the potential drifts linked to the abusive use of metaphor, particularly war
metaphor (Jamet 2006; Semino 2021). However, everyday discourse is still often
populated with war metaphors, in a wide variety of fields. Our study focuses on
the discursive realizations of the word "lutte" (struggle, fight) as a linguistic expression linked to the conceptual metaphor of war: we will analyze privileged collocations of this
metaphor in the French language in three corpora based on media communication, as well as in three corpora of institutional discourse, in order to verify similarities and divergences in a diaphasic and diatopic perspective
Variations on the Author
Full text link“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 linkWe 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
Structure and career advancement in cardiology in Italy
No full textWomen are less present on the labor market and many studies have demonstrated the existence of gender differences regarding participation rate and career advancement of women. The process through which job-, career- and research-related choices are structured within the realm of Italian cardiology, is described in this study emphasizing the effects of productivity, gender and family commitments. In June 1996, a questionnaire was mailed to all members of the Italian societies of cardiology. It included mainly (pre-coded) set-choice questions concerning individual characteristics, career-related data, and information pertaining to teaching, scientific and research activity. Returned questionnaires numbered 1715 (21.4% of the total mailed), 83% were completed by males and 17% by females. For both hospital and academic careers, advancement in rank was influenced by variables denoting productivity, family and individual characteristics. Promotion to the upper ranks of the hierarchy was highly dependent upon time (once the effects of the covariates were eliminated). This is a situation that is typical of the internal labor market, that is, of an institution in which staff members are ranked on a hierarchical scale according to formal criteria that are "rigid" and institutionalized, partially and totally sheltered from competition. Therefore, once a member has gained access to the first level of the hierarchy, his/her professional career is to a certain extent pre-determined and the seniority ends up taking on importance in promotion decisions to an appreciable extent; in this field, the weight of seniority on promotion ranges between 30 and 50%

Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
