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

The brand management system : mediator in the relationship between market orientation and brand performance
No full textLes systèmes de management de marque (BMS) sont d’une importance centrale pour contrôler de façon efficace le management de marque et mettre en valeur la performance de l’entreprise. Une difficulté actuelle concerne l’évaluation des pratiques des managers de marque et leurs contributions à la performance. Cette recherche doctorale tente de pallier cette limite de plusieurs manières : (1) en identifiant les pratiques saillantes et composantes du BMS ; (2) en définissant une échelle de mesure du BMS ; (3) en testant son rôle médiateur dans la relation entre le concept d’orientation marché et la performance marque ; (4) en déterminant globalement , mais aussi sectoriellement, les pratiques saillantes du management de marque qui contribuent à la performance marque mesurée de façon subjective et objective, ainsi que les effets ; (5) en étudiant le rôle de variables qui pourraient modérer cet effet médiateur. Les résultats d’une analyse de sentier auprès de 359 managers de marque confirment l’existence de l’effet médiateur du système de management de marque. Nous démontrons qu’il existe également un chemin médiateur passant par cet effet et ayant un impact sur la performance subjective de la marque puis la performance financière objective. Les analyses multi-groupes mettent en avant des différences sectorielles dans la valorisation des pratiques du management de marque et de l’orientation marché, fournissant ainsi des éléments d’information pour la prise de décision du top management.Brand management systems (BMSs) are of prime importance to monitor an effective brand management and enhance firms’ performance. The lack of research about brand management practices makes the evaluation of their impact on performance difficult to assess. In order to fill this gap, this doctoral research tries to: (1) identify the BMS’s main practices and components; (2) define a BMS scale; (3) test the BMS mediating role in the relationship between market orientation and brand performance; (4) determine to what extent brand management systems contributes to brand performance, measured at subjective and objective levels, globally and in five sectors; (5) study the moderating effects of firms’ and sectors’ characteristics. The research was carried out with a sample of 359 managers. The results demonstrate the mediating effect of BMS on subjective brand performance to objective financial performance. Multigroup analyses show moderating effects which influence BMS and market orientation valuation, which provides relevant information for top managers’ decision making
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
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
