Apport des données altimétriques lidar à la compréhension des zones humides : Deux cas d'étude de mise en valeur antiques et médiévales
No full textAbstract
L’analyse des données altimétriques, acquises par télédétection lidar (laser aéroporté), permet de détecter des traces de mise en valeur des zones humides qui remet ces espaces au coeur du système productif des territoires du passé et non pas systématiquement à leur marge. Pour illustrer le potentiel de la technologie lidar pour l’archéologie des paysages, cet article présente deux cas d’étude l’un en Franche-Comté et l’autre en Languedoc oriental
Faciès mobiliers et espaces rituels, Les ensembles des sanctuaires laténiens du IVe au Ier siècle av. J.-C.
No full textCette contribution dresse en premier lieu un tableau de l’évolution générale des pratiques religieuses fondée sur la comparaison des faciès de mobiliers principalement métalliques dans les sanctuaires structurés d’époque laténienne. Après une définition de six faciès récurrents, elle juxtapose la composition des ensembles de lieux de culte avec leur architecture pour tenter de définir des pratiques relatives à des plans spécifiques. Une fois cette comparaison réalisée, l’étude s’attache à comparer les faciès de mobilier et la répartition des artefacts sur les lieux de culte en confrontant les données issues des différentes unités architecturales des sanctuaires de Corent et de Mirebeau-sur-Bèze. La réunion de ces différents aspects mène à un premier bilan de l’évolution des pratiques en fonction des plans des lieux de cultes et de leurs aménagements.
This study focuses, within structured sanctuaries, on the composition of assemblages and the distribution of the different categories of artifacts in cult places during the second Iron Age. First, the purpose of the study is to revisit the evolutionary vision of metal objects related to specific sacred architectures. The second objective aims to investigate the assemblages of different architectural units within sanctuaries. In order to identify recurring gestures and preferential places of deposit, the study compares the spatial distribution of specific artifacts. Finally, the combination of both methods intends to provide a better understanding of the deposit practices among the different sanctuaries architectural entitie
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
Making digital practices in archaeology meaningful : the example of the Bibracte excavation sites
No full textCette thèse explore la transition vers une archéologie numérique et ouverte. Elle se penche sur la faisabilité d'une fouille archéologique basée sur des logiciels libres, produisant des données transparentes, structurées et aux formats ouverts. Ces vingt dernières années correspondent en effet à une intensification majeure des usages de technologies numériques en archéologie, impactant la collecte, le traitement, la gestion, la conservation et la diffusion des données. L'approche de la science ouverte offre alors les solutions pour contrôler, exploiter et assurer la conservation de ces nouvelles données. Prenant pour cadre d'expérimentation quatre années de fouilles sur l'oppidum de Bibracte, ce travail examine ainsi les défis d'aligner la production de données sur les principes de la science ouverte, dès la phase de terrain. Il cherche également à sortir des considérations techniques pour éclairer les effets de l'archéologie numérique sur l'utilisateur et son environnement. Ce projet souhaite ainsi contribuer à la modernisation des méthodes archéologiques, en développant des pratiques numériques qui prennent en considération les objectifs des archéologues sur le terrain, en plus d'inscrire leur démarche dans un processus de maîtrise, de partage et de pérennisation de la connaissance archéologiqueThe thesis examines the move to open, digital archaeology. It investigates the feasibility of free software-based archaeological excavations producing transparent, structured data in open formats. Over the past two decades, the integration of digital technologies in the field of archaeology has increased considerably, affecting the collection, processing, management, preservation and dissemination of data. The open science approach offers solutions for the management, use and protection of this new type of data. This study uses a four-year excavation of the Bibracte Oppidum as a framework to test how open science principles can guide data production during fieldwork. Moreover, it aims to offer insights into the impacts of digital archaeology on its users and surroundings beyond technical concerns. The project aims to modernise archaeological methods by developing digital practices that consider fieldworkers' objectives and integrate their approach into a process of mastering, sharing and preserving archaeological knowledge
