Quelques données sur les occupations mésolithiques du clos de Poujol (Aveyron)
Full text linkABSTRACT Results of archaeological investigations conducted at Clos de Poujol (Aveyron, France) in 1990 are presented in this paper, with an outline of the site potential. The deepest sediments of the recorded archaeological stratigraphy (G) include Early Neolithic and Mesolithic occupation levels. The collected lithic assemblage from the Gj deposit, submitted to detailed analysis, is presented here ; reliable contexts (structures) appear to be highly relevant for the assessment of the variability of Sauveterrean industries. Furthermore, preliminary results of geoarchaeological, archaeobotanical and archaeo- zoological analyses are presented.RÉSUMÉ Cet article présente les premiers résultats des recherches archéologiques effectuées au Clos de Poujol (Aveyron, France) en 1990. L'ensemble sédimentaire le plus profond (G) comporte des horizons néolithique ancien et mésolithiques. Les premiers éléments des analyses géoarchéologiques, carpologiques et archéozoologiques sont présentés. L'ensemble lithique du dépôt G/ est étudié en détail et sa signification évaluée. Il apparaît que l'analyse des industries définies dans des contextes de dépôts très précis (structures) pourrait apporter des réponses aux questions que pose la variabilité des assemblages lithiques sauveterriens.Bobœuf Marc, Bridault Anne.

Les occupations mésolithiques et du néolithique ancien sur le site de la Grange à Surgères (Charente-Maritime)
No full textThe archaeological site of La Grange présent one fo the very rare stratigraphy in the région of Poitou-Charentes where can be encountered levels from middle Mesolithic period up to the Early Neolithic. The artefacts were founded in a fluvial deposit, no more than 50 cm thick, which also contained various hearth and an occupation level. Despite some taphonomic disturbance, the characteristic éléments from Middle Mesolithic, Late Mesolithic and Early Neolithic organise themselves in a logical cultural sequence.Le site de La Grange présente l'une des rares stratigraphies régionales couvrant toute la période Mésolithique jusqu'au début du Néolithique ancien, voire la seule en Poitou-Charentes qui fut étudiée en détail. Les vestiges archéologiques sont contenus dans un dépôt argileux, épais tout au plus de 50 cm, correspondant à une dynamique fluviatile faible, de type bras mort, où alternent phases d'inondation et d'exondation reliées à chacune des occupations successives du site. Un sol d'occupation très riche en mobilier osseux et quelques structures de combustion ont été dégagés. Bien que des phénomènes taphonomiques propres aux établissements de bord de berge inondable de ce type ait généré une forte compaction des vestiges archéologiques, les éléments caractéristiques des occupations du Mésolithique moyen, puis récent et du Néolithique ancien, s'étagent logiquement dans la stratigraphie.Laporte Luc, Marchand Grégor, Sellami Farid, Oberlin Christine, Bridault Anne.

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
