Shoreline mobility and human occupation in the Emirate of Abu Dhabi during the Holocne
No full textLes littoraux d’Abu Dhabi, et plus largement ceux du golfe Arabique, ont joué un rôle majeur dans le développement des populations humaines au cours de l’Holocène. Parallèlement, ces milieux apparaissent également comme des espaces très vulnérables. En plus d’être soumis aux variations climatiques régionales, ils ont été fortement exposés aux mobilités des lignes de rivage, contrôlées en partie par les variations du niveau marin. L’étude de ces fluctuations s’avère ainsi essentielle pour reconstituer les évolutions paléogéographiques des littoraux dont dépendaient les sociétés. La thèse présente une synthèse de ces variations et des changements paléoenvironnementaux associés, soutenue par l’apport de nouveaux résultats issus d’un travail de terrain, par l’examen des recherches déjà publiées et par un travail de modélisation reposant sur la création de Sea-Level Index Points, à Abu Dhabi mais aussi sur l’ensemble de la rive sud du Golfe. Selon une approche géoarchéologique, l’étude cherche simultanément à replacer les sites dans leurs contextes paléoenvironnementaux. En dépit de variations métriquement réduites, les résultats indiquent des impacts considérables sur la morphologie des littoraux, marqués par de très faibles élévations. Ils permettent également d’expliquer en partie la répartition des sites archéologiques. Enfin, ils attestent de l’existence de variations relatives du niveau marin, résultant de dynamiques de surrection et de subsidence des masses terrestres. Les trajectoires identifiées traduisent de fortes disparités régionales et mettent en lumière la complexité et l’imbrication des mécanismes isostatiques, néotectoniques et diapiriques.The coastlines of Abu Dhabi, and more broadly, those of the Arabian Gulf, have played a major role in the development of human populations during the Holocene. At the same time, these environments appear to be highly vulnerable. In addition to being subject to regional climatic variations, they have also been heavily influenced by shoreline mobilities, partially controlled by sea-level fluctuations. Studying these fluctuations is therefore essential for reconstructing the paleogeographic evolution of the coasts upon which societies depended. This thesis presents a synthesis of these variations and associated paleoenvironmental changes, supported by the contribution of new fieldwork results, a review of previously published research and modelling work based on the creation of Sea-Level Index Points, both in Abu Dhabi and across the entire southern shore of the Gulf. Adopting a geoarchaeological approach, the study integrates archaeological data to replace archaeological sites within their paleoenvironmental context. Despite relatively small metric variations, the results indicate significant impacts on shoreline morphology, marked by very low elevations. They also enable archaeological maps to be put into perspective. Lastly, they confirm the existence of relative sea-level variations resulting from landmass uplift and subsidence. The identified trajectories reveal substantial regional disparities and underscore the complexity and interplay of isostatic, neotectonic and diapiric mechanisms
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
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
