The immigrant nearing old age.
No full textVieillir immigré est devenu une situation commune à un nombre grandissant de personnes en France. En 2015, près d’1,5 million de personnes immigrées étaient âgées de 60 ans et plus. La constante augmentation du nombre d’immigrés âgés constitue une question sociale et politique en France, ce qui a été confirmé tant par les récents travaux de l’Assemblée nationale que par l’avancée des connaissances scientifiques. Le nombre de travaux produits sur des territoires différents, là où les migrants âgés sont plus ou moins présents démographiquement reste encore aujourd’hui restreint. Face à ce constat, l’objectif de cette thèse par articles est de proposer une lecture territoriale et gérontologique de la vieillesse en migration. Deux terrains d’étude ont été retenus dans le cadre du projet doctoral (premièrement, les villes d’Angers et de Cholet en Maine-et-Loire et deuxièmement, la Ville de Montreuil en Seine-Saint-Denis). Les terrains de recherche ont été l’occasion d’analyser les conditions de vieillissement des personnes immigrées dans des contextes spatiaux différents (analyse des données territoriales et du discours des acteurs médico-sociaux, associatifs et politiques intervenants auprès des immigrés vieillissants). Dans la continuité, une analyse des récits biographiques d’un échantillon de migrants âgés résidant en Maine-et-Loire a été effectuée pou mettre en exergue les enjeux sociaux et spatiaux structurant les expériences de vieillissement des immigrés. Les résultats de recherche produits témoignent de la nécessité d’appréhender l’hétérogénéité de ces publics et d’étudier leurs besoins en regard de leurs parcours et des espaces qui structurent leur (fin de) vie.In France, getting old as an immigrant became a condition shared by a growing number of people. In 2015, about 1.5million of immigrants are 60years old or more. In France, the constant increase in the number of elderly immigrants represents a social and political issue, a fact confirmed by the recent works of the national assembly as well as by the development of scientific research. Nonetheless, the diversity of studies dealing with different territories inhabited by elderly immigrants remains limited. Consequently, this thesis (structured around several scientific articles) aims at proposing a representation of the “migrating elderly”, articulating a territorial and gerontological approach. Two different territories were taken into consideration: Angers andCholet (Maine-et-Loire), and Montreuil (Seine-Saint-Denis).This selection provided the opportunity to analyse the aging conditions of migrating population which evolve according to different spatial contexts. In this study, we considered territorial data, medico-social accounts, as well as the work of associations and political interventions to elderly immigrants.In addition, biographical facts and stories from as ample of elderly migrants in Maine-et-Loire were analysed to highlight the political and social issues that structure the aging conditions of immigrants.The result of this work proves that it is still essentia lto take into account the heterogeneity of these populations. It also underlines the importance of understanding their needs in terms of their own life journeys (and the end of it) which is inextricable of the territory they occupy
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
