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
Suivi en continu des températures et conductivités des eaux thermales en contexte hyper minéralisé. Salins-Les-Thermes, Savoie
No full textThe specificity of the Salins les Thermes thermal waters and the site development disturb the acquisition of the water temperature and electrical conductivity from continuous monitoring. Since the accessibility of the measuring devices is limited at a short period of the year, the devices record the disturbances attributed to the clogging of the probes by iron oxides and to the probable degassing of CO2. These disturbances result in a phenomenon of oscillation at high frequency of measurements and a drift more or less marked according to the types of probes and their positioning.La spécificité des eaux thermales de Salins-les-thermes et l’aménagement du site perturbent l’acquisition des suivis en continu de la température et de la conductivité électrique des eaux. L’accessibilité aux dispositifs de mesures étant limitée durant une période de l’année, ces derniers enregistrent les perturbations attribuées au colmatage des sondes par des oxydes de fer et probablement au dégazage de CO2. Les perturbations se traduisent par un phénomène d’oscillation à haute fréquence de mesures et une dérive plus ou moins marquée en fonction des types de sondes et de leur positionnement.Malet Emmanuel, Dzikowski Marc, Fanget Bernard, Doublet Camille, Gasquet Dominique.

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
Contrôle du remplissage détritique tardiglaciaire à holocène d'une haute vallée alpine par les dynamiques de versant : l'exemple de la moyenne Maurienne (Savoie) [Late glacial holocène infill in a high alpine valley : the Maurienne valley (Savoie)]
No full textAlluvial fans represent the main geomorphological feature of the narrow Valley between the Saint Jean de Maurienne et Saint Michel de Maurienne glacial ombilics.
A sedimentary body reconstruction of the nested cones was carried out from the geomorphological and the geophysical data and from drillings managed by EDF and Alpetunnel.
Fossilised wood permitted a stratigraphie time calibration and a paleogeographic evolution is proposed. The late glacial fill is highly controlled by lateral torrential deposits, mud flows, rock collapses and landslides. These deposits have created a dam and permitted an upstream lacustrine deposit.Les cônes de déjection constituent le trait morphologique majeur de l'étroite vallée de l'Arc (Savoie), entre les ombilics de Saint-Jean- de-Maurienne et Saint-Michel-de-Maurienne.
Une reconstitution géométrique des différents corps sédimentaires constitutifs de ces cônes a été rendue possible grâce à une étude géomorphologique, à la synthèse des données de forages de diverses campagnes de reconnaissance pour EDF et Alpetunnel et à l'utilisation de résultats géophysiques.
Un calage stratigraphique a été établi à partir de datations de bois fossilisés puis une évolution paléogéographique est proposée. Elle montre que, dans cette partie de la vallée, le remplissage tardiglaciaire à holocène est fortement contrôlé par les dépôts torrentiels latéraux à laves, des écroulements rocheux massifs et des glissements de terrain. En barrant cette étroite vallée, ces dépôts gravitaires favorisent localement une sédimentation lacustre.Crouzet Christian, Nicoud Gérard, Fudral Serge, Rampnoux Jean Paul, Dzikowski Marc, Paillet André, Lacombe Patrick.
