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
Analyse clinique de la polykystosetrenale autosomique dominante
No full textLa polykystose rénale autosomique dominante (PKAD) est due à la mutation des gènes PKD1 ou PKD2 pouvant aboutir à l'insuffisance renale terminale. Nous avons étudié les caractéristiques cliniques de 533 patients polykystiques bretons. La survie renale est meilleure chez les patients PKD2, les femmes, ceux dont l HTA ou les douleurs kystiques sont apparues apres l'âge de 35 ans. 81% des patients sont hypertendus. Seuls 51% ont une tension artérielle systolique inferieure à 140 mmHg. Les manifestations de la PKAD sont identiques selon le genotype PKD1 ou PKD2 mais apparaissent plus precocement pour les premiers. Les hommes polykystiques ont un terraincardio-vasculaire plus à risque que les femmes. Les patients au stade 1 de la maladie rénale presentent des reins plus petits, moins fréquemment d HTA, de complications cardio-vasculaires. Le diagnostic de polykystose au stade initial, dans certains cas par analyse genetique, permettrait d entreprendre précocement les mesures de protection cardio-vasculaires et ralentissant, voire à l avenir bloquant l'évolution de la PKAD.BREST-BU Médecine-Odontologie (290192102) / SudocSudocFranceF
Evaluation des troubles du rythme cardiaque dans une population des dialysés brestois
No full textLa première cause de mortalite chez le patient dialyse est d ordre cardio-vasculaire. La fréquence des décès par mort subite est importante puisqu elle est estimée entre un quart à un tiers de la mortalité globale des dialyses. Nous avons réalisé une etude des troubles du rythme cardiaque dans notre population de patients dialyses (37 patients). Ils ne présentent pas plus d arythmies supra-ventriculaires que des témoins non insuffisants rénaux mais ayant des comorbidités cardiovasculaires (32 témoins). Par contre, les dialysés développent significativement plus d extrasystoles polymorphes (p = 0,002). Ces troubles du rythme sont retrouvés pendant la séance de dialyse mais aussi à distance de la période dialytique. La variabilité sinusale est inferieure a 80 millisecondes pour 53% des dialyses, ce qui temoigne d un risque de mortalité cardiaque majeur. Nous avons ensuite comparé la nature et la fréquence des troubles du rythme chez 17 patients sous deux techniques de dialyse: l AFBK (Biofiltration avec profil de potassium) et l hémodialyse au bicarbonate. Nous n avons pas identifié de différence significative, Notre étude suggère que les patients hémodialysés présentent plus de troubles du rythme ventriculaires graves, exposant ainsi à un risque plus important de mort subite.BREST-BU Médecine-Odontologie (290192102) / SudocSudocFranceF
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
