Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Terra e territorialità in Sicilia in età classica: l’apporto delle fonti epigrafiche
No full textLes inscriptions grecques de Sicile datées entre la fin du vie et la fin du ive siècle av. J.-C. donnent des informations sur l’importance de la terre comme ressource déterminante des rapports entre les colonies grecques de Sicile, et sur le territoire comme lieu d’exercice du pouvoir. À partir de l’analyse des textes épigraphiques, il est possible de réfléchir à une dynamique commune, qui est bien décrite par les sources littéraires et qui est aussi suggérée par la documentation archéologique : la terre est soit une ressource qui pousse les hommes à instituer de nouvelles colonies et qui encourage des rapports entre les centres de la Sicile, soit un lieu et un instrument de l’exercice du pouvoir des tyrans à travers les processus de territorialisation (fondation de colonies), déterritorialisation (transfert des peuples), tout en restant un élément clé de la conscience identitaire du citoyen.Greek inscriptions from Sicily dating between the end of the 6th and the end of the 4th century BC. give us some information about the importance of the land as a resource that affected the relationship between Greek Sicilian colonies and about the territory as a place of power. From the analysis of epigraphic texts it is possible to reflect on a general dynamic, which is well described by the literary sources and which is also suggested by the archaeological data: the land is a resource which induces men to found new colonies and which encourages relations between the Sicily places and at the same time an instrument of the tyrants’ power through the processes of territorialization (colonies foundation), deterritorialization (peoples removal), and also a key element of the identity sensibleness of each citizen
