Un faciès solutréen particulier en Aquitaine : le Solutréen de Montaut (Landes) / Solutrean Local Facies in Aquitania : Montaut (Landes) Solutrean Site
No full textSolutrean local facies in Aquitania : Montaut (Landes) solutrean site. This presentation concerns the bifacial Solutrean pieces of the site of Montaut (Landes). This
site discovered by Mascaraux en 1889, seems now, totally destroyed. P.E. Dubalen (a local prehistorian and naturalist, first curator of the Museum of Natural History of Mont-de-Marsan) dug there and collected an abondant lithic assemblage. Then the site was surveyed by J. de Lapoterie and Letailleur and by M. Neuville. Besides the Solutrean remains, they were Gravettian, Aurignacian and Azilian indices. The material collected in Montaut is scattered in several public and some private collections. We present here, the mode of manufacture ot these pieces and their morphological variability, particularly the shape of their proximal end. This site is replaced in the close regional context, where similar elements have been in most cases, wrongly mentioned.Cette présentation concerne les pièces bifaciales du gisement de Montaut (Landes). Ce gisement découvert par F. Mascaraux en 1889, semble aujourd’hui complètement détruit. Il fit également l’objet des recherches de P.E. Dubalen (préhistorien et naturaliste landais, fondateur du Muséum d’Histoire naturelle de Mont-de-Marsan) qui y recueillit une abondante série lithique. Il fut aussi prospecté par J. de Laporterie et Letailleur, puis par M. Neuville et outre la série solutréenne, il a livré des indices de Gravettien, d’Aurignacien et d’Azilien. Le matériel recueilli à Montaut est dispersé dans différentes collections pour la plupart publiques. Notre propos portera plus particulièrement sur le mode de fabrication de ces pièces et leur variabilité morphologique, notamment en ce qui concerne le traitement de la base et nous replacerons ce gisement dans le contexte d’autres gisements du piémont pyrénéen où des éléments similaires ont souvent été signalés à tort.Lenoir Michel, Merlet Jean-Claude.

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
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
Sorde-l’Abbaye – Abri du Grand Pastou
Get PDFL’année 2017 a marqué l’achèvement de l’opération d’évaluation-diagnostic menée à l’abri du Grand Pastou depuis 2014. La campagne 2017 s’est focalisée sur la partie du gisement considérée comme la mieux conservée, c’est-à-dire une étroite terrasse au-devant de l’abri, dominant un talus de 20 m en pente raide (60°). La fouille des niveaux magdaléniens a été menée à son terme, le socle rocheux ayant été atteint. En ce point du gisement, les dépôts sont épais de 115 cm. Ils sont formés surtout d..
