    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    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

    Identité et imaginaire social : l'exemple de Ticopó, Yucatán

    Ce mémoire présente les résultats d'une recherche effectuée à Ticopô, village maya situé dans la zone henequenera du Yucatân, au Mexique. Dans une approche constructiviste enrichie par l'apport de l'économie politique, l'auteure s'intéresse à la construction de l'identité de la femme maya au Yucatân, en lien avec l'imaginaire social. Un chapitre portant sur la construction des identités autochtones au Mexique permet de situer cet imaginaire social dans une perspective historique globale. L'auteure examine ensuite les processus par lesquels des hommes et des femmes mayas de différentes générations (enfants, jeunes et adultes) incorporent, contestent ou négocient des critères identitaires de toutes sortes (apparence physique, domaines d'activité, rapports sociaux, etc.) véhiculés par diverses manifestations symboliques de l'imaginaire social à Ticopô. Elle privilégie pour cela l'étude de manifestations symboliques locales : théâtre indigène (teatro indigena), événements importants dans l'année ou dans la vie d'une personne, histoires racontées et conseils donnés aux enfants.This Master's thesis presents the results of a research study conducted in Ticopô, a Maya village located in the henequenera zone of Yucatân in Mexico. Using a constructivist approach, enriched by the contribution of political economies, the author studies the construction of the identities of Maya women in relation with the social imaginary. A chapter focusing on the construction of aboriginal identities in Mexico helps put this social imaginary in a global historical perspective. The author then analyses the processes by which Maya men and women of different generations (children, teenagers, and adults) incorporate, oppose, or negotiate identity criteria of ail sorts (physical appearance, field of activities, social relations, etc.) conveyed by various symbolic manifestations of the social imaginary in Ticopô. The author's methodology favours the study of local symbolic manifestations: Aboriginal theatre (teatro indigend), important annual or one-time events in the life of a person, stories being told, and advice being given, to children

    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

    La migration et le développement dans une municipalité maya du Yucatán : Des possibilités envisageables, une accessibilité relative

    No full text
    Ce mémoire aborde les effets de la mondialisation économique sur une population rurale hautement marginalisée. Plus précisément, il met en relation les dynamiques du développement et de la migration dans une municipalité autochtone du sud du Yucatán au Mexique. En comparant la participation aux projets de développement générateurs de revenus et la possibilité de migrer, l’auteure tente de déterminer ce qui incite la population à se tourner soit vers les projets de développement, soit vers la migration. Le genre, l’appartenance ethnique – plus précisément les capacités langagières – et le statut socioéconomique s’avèrent des éléments fort révélateurs pour comprendre la participation à ces activités. Ainsi, les femmes les plus marginalisées, ciblées par les agents du développement, semblent échapper aux projets et avoir plus de difficulté à migrer. Cette recherche révèle aussi que le facteur ethnique joue un rôle important quant aux possibilités de migrer ou de participer à un projet de développement. Dans la communauté rurale de Chacsinkín, presque la totalité de la population parle la langue maya, mais la maîtrise de l’espagnol comme langue seconde est déterminante dans la participation à un projet de développement ou la migration. Enfin, les possibilités de participer à un projet de développement et de migrer sont influencées par le statut socioéconomique de chacun et chacune et sont plus faciles d’accès pour les personnes intégrées aux réseaux locaux les plus puissants sur les plans économique et politique.This thesis is about the effects of economic globalization on a highly marginalized rural population. More specifically, it examines the relations between development and migration in a municipality of Southern Yucatan, in Mexico. The author tries to reveal what fosters or hinders people to participate in development projects and to migrate toward national destinations or to another country. Gender, ethnicity – more specifically language capabilities –, and socioeconomic status are important elements for understanding participation in those activities. The most excluded women, targeted by development agencies, seem to be unable to take part in the projects and they migrate with more difficulties. Ethnicity also plays an important role. In the community of Chacsinkín, almost everyone speaks the maya language, but Spanish as a second language is a facilitating factor for participation in development projects and migration. Finally, participation in development projects and migration is influenced by socioeconomic status and are easier for those who are included in the most powerful political and economic networks

    Appropriate Similarity Measures for Author Cocitation Analysis

    Full text link
    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

    Full text link
    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
