Microliths use in western mediterranean during VI-V Millenium BC
Get PDFGeometric microliths have been often considered as an important cultural and chronological marker for the study of lithic assemblages, especially for European Mesolithic and Neolithic. However, systematic studies on microlith function are still lacking. In this paper we present a synthesis of microwear analysis realized on a number of sites, in Western Mediterranean, dated between the VI-V millennium. Our objective is to investigate the significance and the recurrence of those instruments within a spectrum of different contexts. Results indicate that, within a global tendency for microliths use as hunting weapons, there is a certain degree of variability on the basis of environmental, economical and cultural factors that strongly influence their production and mode of use
Le travail de la poterie en contexte chasséen : des outils en silex pour la production céramique ?
No full textThis paper aims to review the data concerning use-wear traces on pottery-working flint tools. Some case studies in the context of the Southern Chassey are presented ; the tools are grouped by mode of operation to try to situate them in the chaînes opératoires of ceramic production. Finally, there is further reflection on the technological and social implications of the identification of these tools.Cet article a pour objectif de faire un point critique sur les données tracéologiques permettant de caractériser les outils en silex ayant travaillé la poterie. Quelques études de cas dans le contexte du Chasséen méridional sont présentées, les outils étant regroupés par mode de fonctionnement pour tenter de les replacer dans la chaîne opératoire de la production des céramiques. Enfin, une réflexion approfondie est menée sur les implications technologiques et sociales de l’identification de ces outils.Torchy Loïc, Gassin Bernard.

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
Le silex bédoulien sur les sites chasséens du Languedoc : étude fonctionnelle, statut des sites et réseaux de diffusion
Get PDFOur study focuses on the management of Bedoulian flint productions in the Chassey Culture, on importer and consumer sites in Languedoc, which are in the zone of mass diffusion and relatively close to each other, but far from workshop producer site. These sites are Le Pirou in Valros (Hérault), Armissan in Langel (Aude) and Auriac in Carcassonne (Aude). Management differences were observed between the different productions (with or without heat treatment ; between blades/ bladelets/ flakes and between different rhythms of knapping) and between different sites. The sous-systèmes techniques of plant cutting, skin, bone and ceramic working are discussed by addressing the issue of craft specialization. Different site statuses are identified through the representation of different functional classes. The strong representation of plant cutting at Le Pirou and Langel shows them to be related to agriculture, while the functional spectrum of Auriac reveals a very different status from the two others. The functional analysis introduced some ideas supporting the hypothesis of bladelets (knapped by pressure after heat treatment) redistribution site. Finally, the complexity of the diffusion of Bedoulian flint is approached through a demonstration of supply ease variability, revealing different levels of integration in exchanges systems.Notre étude porte sur la gestion des productions lithiques en silex bédoulien sur des sites chasséens languedociens importateurs et consommateurs compris dans l’aire de diffusion massive et relativement proches les uns des autres, mais éloignés des ateliers producteurs. Il s’agit des sites du Pirou à Valros (Hérault), de Langel à Armissan (Aude) et du fossé St2 d’Auriac à Carcassonne (Aude). Des différences de gestion ont été observées entre les différentes productions (avec ou sans traitement thermique ; entre lames/ lamelles/ éclats ; entre différents rythmes de débitage), mais aussi entre les différents sites. Les sous-systèmes techniques de la coupe des végétaux, du travail de la peau, de l’os et de la céramique ont pu être discutés en abordant la question de la spécialisation artisanale. Différents statuts de sites ont pu être mis en évidence grâce à la représentation des différentes classes fonctionnelles. La forte représentation de la coupe de végétaux sur les sites du Pirou et de Langel leur confère une vocation agricole, tandis que le spectre fonctionnel d’Auriac révèle un statut bien différent des deux autres. L’analyse fonctionnelle a introduit quelques pistes de réflexion confortant l’hypothèse d’un site redistributeur de lamelles débitées par pression après traitement thermique. Enfin, la complexité des réseaux de diffusion des silex bédouliens a été abordée par la mise en évidence d’une variabilité d’aisance d’approvisionnement révélant différents degrés d’intégration dans ces réseaux.Torchy Loïc, Gassin Bernard.

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
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
