Les épisodes de gel du Rhône depuis l'An Mil. Périodisation, fréquence, interprétation paléoclimatique
No full textBy means of cautions historical research, ancient written sources allow us to work out the chronology of ice advents on the Rhône river and to determine the occurrences of such an event. The latter is a heat and hydrological pointer for some conspicuous winters since the year 1000. It joins with climatic history, and its frequency variations fit into tendencies, other climate flutters have revealed. The frost of the Rhône river so constitutes an important datum to the analysis of climatic arrangements which are peculiar to those periods.Les sources écrites anciennes, moyennant les précautions de la recherche historique, permettent d'établir la chronologie des apparitions de glace sur le Rhône et d' apprécier les manifestations de cet événement. Ce dernier est un indicateur thermique et hydrologique des hivers les plus remarquables depuis l'An Mil. Il s'intègre à l'histoire climatique et les variations de sa fréquence s'inscrivent dans des tendances que d'autres marqueurs du climat ont mis en évidence. Le gel du Rhône constitue ainsi une donnée importante de l'analyse des combinaisons climatiques qui ont caractérisé ces périodes.Jorda Maurice, Roditis Jean-Christophe.

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
Dynamiques fluviales et milieux de sédimentation du Rhône à l'amont immédiat de son delta
No full textThis article propounds to determine the river dynamics of the Rhone at the delta-head. It connects the knowledge of hydrosedimental dynamics and the local factors of their space distribution over the Rhone riverine environment ; to the characterisation of the suspended matters conveyed by the river, immediately above its costal plain. This evaluation of conveyed sedimentary stocks, temporaty got together or inherited in the delta-head area, is a mean point for the understanding of recent evolution of the supply conditions in the Camargue laminarian zone.Cet article propose de déterminer les dynamiques fluviales du Rhône en tête de son delta. Il associe la connaissance des dynamiques hydrosédimentaires et des facteurs locaux de leur répartition spatiale sur les milieux rivulaires du Rhône à la caractérisation des matières en suspension transitant par le Rhône en amont immédiat de sa plaine littorale, notamment au cours d'une crue caractéristique. Ce bilan des stocks sédimentaires en transit, stockés provisoirement ou hérités, en tête de l'aire deltaïque est essentiel à la compréhension de l'évolution récente des modalités d'alimentation de la frange littorale camarguaise.Roditis Jean-Christophe, Pont Didier.

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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
