Territoires et acteurs des risques "naturels" en Amérique latine : les cas des villes de Managua (Nicaragua) et de Quito (Equateur) (Political decision makers and territories of the "natural" risks in Latin America. : the cases of Managua (Nicaragua) and Quito (Equator) cities))
No full textThe comparison between the Latin-American cities of Managua and Quito helps to understand the role of the political decision makers in the construction of the territories of risks. The article underlines the gap between hazardous areas and the territories of risks. Perception, and the way its developed, contributes to create these territories. The decision makers can even use them as alibis with the aim of developing convenient territorial processes.La comparaison des villes latino-américaines de Managua et de Quito sert à comprendre le rôle des acteurs politiques dans la construction des territoires des risques. L'article souligne le décalage entre l'inscription des aléas et les territoires du risque. Les représentations, par leur mode de production contribuent à créer ces territoires du risque. Elles constituent même parfois pour les acteurs politiques des alibis pour développer d'opportunes stratégies territoriales.Hardy Sébastien, Sierra Alexis.

Comprendre les enjeux pour établir les vulnérabilités des aires urbaines de haute altitude. Cas de La Paz et de Quito. (Understanding challenges to assess the vulnerabilities of high-altitude urban areas. The cases of La Paz and Quito)
No full textLa Paz and Quito are two metropolises located in the heart of the tropical Andes. They are frequently damaged by natural events. Vulnerability has been consequently imputed to the mountain tropicality. Nonetheless, tropical environment is only one vulnerability element between many others. The vulnerability of these Andean metropolises should be discussed according to their level of development, the form of their organisation and the ability to lose some elements of development.La Paz et Quito sont deux métropoles situées au cœur des Andes tropicales. Elles sont fréquemment endommagées par des événements d'origine naturelle. C'est pourquoi on attribue leur vulnérabilité à la tropicalité de montagne. Pourtant, le milieu n'est qu'un facteur de vulnérabilité parmi d'autres. La vulnérabilité de ces métropoles andines dépend fortement de leur mode de développement et de fonctionnement, et de la mise en exposition de certains enjeux.Hardy Sébastien, Sierra Alexis.

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
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
