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
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
Butchering behind closed doors : examining the breaking of social and family relationships. The case of the genocide against the Rwandan Tutsis in 1994
No full textComment peut-on en arriver à vouloir exterminer une partie de ceux que l’on a connus, y compris ses plus proches ?À l’exemple significatif entre tous de cette femme dans le camp de réfugiés de Ravucindu « hutue mariée chez les tutsis » qui pose son enfant et part, « laissant là mourir de faim son fils, parce que son père, seulement, est tutsi » ; à l’exemple encore de ce prêtre de père hutu, aujourd’hui emprisonné à Muhanga, et qui torture sa mère tutsie tous les jours, jusqu’à ce qu’elle se suicide ; ou ce jeune milicien qui attaque à l’épée un stade où se sont réfugiés des milliers de personnes puis retrouve par terre la carte d’identité de son oncle maternel et se demande en haussant les épaules : « Est-ce moi qui l’ai tué, celui-là ? ». Comment est-il possible de rompre de façon aussi massive des liens qui semblent indestructibles ? Car qui peut honnêtement dire qu’il pourrait un jour oublier ses amis, sa mère, son frère ou sa famille ?L’objet de cette thèse est d’essayer de comprendre le mécanisme des ruptures de liens sociaux et familiaux et leur rôle dans le cas du génocide des Tutsis du Rwanda de 1994. Un génocide qui fit près d’un million de morts en cent jours et dont 60% des victimes auraient été tuées par des personnes qu’elles connaissaient là où elles habitaient.Dominé par le souci de chercher une explication qui ait quelque portée générale, ce travail propose, à partir de données empiriques obtenues presque exclusivement de première main (par plusieurs enquêtes successives de terrain au Rwanda, au Bénin et en Afrique du Sud entre 2014 et 2017 ), un cadre d’analyse des ruptures de liens sociaux et familiaux qui peuvent rendre possibles des massacres perpétrés dans la sphère intime au sein d’un projet d’extermination totale d’un groupe par un autre groupe.À la question : « Comment une telle rupture de liens sociaux et familiaux a-t-elle été possible ? », cette thèse répond en mettant en évidence l’importance cruciale d’un processus de double identification. Elle ne nie pour autant nullement le rôle des divers avantages (matériels ou symboliques) dont ont pu bénéficier les génocidaires par leurs crimes dans un tel contexte, mais montre que ces identifications-mêmes ont pu jouer un rôle dans ce calcul coûts/avantages.How can we reach the point where we exterminate some of those we have known, including our loved ones?Like the significant example of this hutu woman, married to a tutsi, from the refugees camp in Raducindu, who left her child lying on the floor, letting him to starve to death, only because his father is a tutsi ; such as that priest, born from a hutu father, and now jailed, who tortured daily his mother, a tutsi, until she committed suicide; or like this young militiaman who slaughtered a crowd with a sword in a stadium where thousands of people had taken refuge and then found on the ground the ID card of his uncle, had a look at it, shrugged his shoulders and wondered "did I kill this one?": how conceivable is this massive severing of ties which seemed otherwise indestructible? Who can expect he would be able one day to forget his friends, his mother, his brother or his family?This dissertation examines the mechanism leading to the collapse of social and family ties and its role in the case of the genocide against Tutsis in 1994 in Rwanda. Close to 1 million Rwandan Tutsis were exterminated over a period of 100 days. It is estimated that 60% of these victims were killed by people they knew.The present work tries to offer an explanation of some general scope by building an analytical apparatus based almost exclusively on empirical data gathered during field research in Rwanda, Benin, and South Africa between 2014 and 2017. This analytical apparatus examines how -within a crisis context - ties can break and lead to massacres in the intimate space of social and family relationships.To the question: "how can such destruction of social and family ties be possible ? ", this dissertation responds by highlighting the pivotal importance of a dual identification process. By doing so, it does not exclude the role played by the various advantages (material or symbolic) which benefited those who committed the genocide, but it demonstrates that these identifications themselves may have weighed strongly in this cost/benefit calculation
