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

Le Néolithique moyen en Languedoc oriental : caractérisation stylistique de la céramique, nouvelles réflexions sur la culture chasséenne
No full textOver the past three decades, the large number of diplomas and collective research projects, supported by the multiplication of preventive archaeology operations have led to a better appeciation of the middle Neolithic in Southern France. In the specific pottery and flint studies field, work on the Garonnais, the Aude valley, the Quercy, the Auvergne, the middle Rhone valley, the Alps and Provence have made it possible to better understand the chronology and the variability of the cultural expressions between 4500 and 3500 B.C. In Eastern Languedoc, a combined approach to the flint and ceramic industries was conducted from the late 1990s. Two parallel theses on both remains types were initiated, but only that on the flint industries was possible (Lea, 2002). However, a synthesis article was used for the first time to compare lithic periodization with a preliminary pottery’s seriation (Georjon and Lea, 2013).The present thesis thus corresponds to the culmination of a work initiated 20 years ago on the ceramic periodization of the Middle Neolithic in Eastern Languedoc. I selected a corpus of 11 series finely analyzed and augmented from various sets addressed more quickly. Most of these series are from my ceramic work on operations of preventive archaeology. Some are unpublished, others partially or entirely published. All the studies already carried out have been completely redone using a unified methodology.The issues developed in this thesis addresses three main aspects: the chrono-cultural and chrono-geographical approach of Eastern Languedoc in the context of the southern Middle Neolithic, the characterisation of ceramic productions and, more broadly, the overview of the Chasséen definition.Chrono-cultural and chrono-geographical issues are at the forefront: how to correlate my periodization with those that exist in the South? What is the place of Eastern Languedoc, a region with contrasting landscapes, limited to the east and west by two rivers of unequal importance (the Hérault and the Rhone) and to the north by the foothills of Massif Central, in the southern domain during this period? The treatment of this aspect is based on an accurate assessment of the archaeological contexts, composition and conservation status of the sets. A crossing of ceramic and lithic periodizations with 14C chronology is also proposed.The analysis of the means for producing the pottery is based on the technological studies available to my corpus.Depuis une trentaine d’années, l’appréciation du Néolithique moyen méridional a beaucoup progressé grâce à un grand nombre de diplômes et de projets collectifs de recherche sur le sujet, appuyés par la multiplication des opérations d’archéologie préventive. Dans le domaine des études céramiques et lithiques, notamment, les travaux sur le Garonnais, la vallée de l’Aude, le Quercy, l’Auvergne, la moyenne vallée du Rhône, les Alpes et la Provence ont permis de mieux appréhender la chronologie et la variabilité des expressions culturelles entre 4500 et 3500 av. J.-C. En Languedoc oriental, une approche conjuguée des industries lithiques taillées et de la céramique a été conduite à partir de la fin des années 1990. Deux thèses parallèles sur ces deux types de mobiliers ont été initiées, mais seule celle de V. Lea sur les industries lithiques a pu voir le jour (Lea, 2002). Un article de synthèse a néanmoins permis de confronter pour la première fois la périodisation lithique avec une sériation céramique préliminaire (Georjon et Lea, 2013). La présente thèse correspond donc à l’aboutissement d’un travail initié il y a 20 ans sur la périodisation céramique du Néolithique moyen en Languedoc oriental. J’ai sélectionné un corpus de 11 séries analysées finement augmenté de divers ensembles abordés plus rapidement. La plupart de ces séries sont issues de mes travaux d’étude céramique sur les opérations d’archéologie préventive. Certaines sont inédits, d’autres partiellement ou intégralement publiées. Toutes les études déjà réalisées ont été entièrement remodelées à l’aune d’une méthodologie unifiée.La problématique développée dans cette thèse aborde trois principaux aspects : l’approche chrono-culturelles et chrono-géographiques du Languedoc oriental dans le contexte du Néolithique moyen méridional, la caractérisation des productions céramiques et, plus largement, l’état des lieux de la définition du Chasséen.Les questions chrono-culturelles et chrono-géographiques sont au premier plan : comment la sériation que je produis est-elle corrélée aux différentes périodisations qui existent dans le Midi ? Quelle est la place du Languedoc oriental, région aux paysages contrastés, limitée à l’est et à l’ouest par deux fleuves d’inégale importance (l’Hérault et le Rhône) et au nord par les contreforts du Massif central, dans le domaine méridional durant cette période
