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
La déglaciation du bassin du Lac Saint-Jean (Wisconsinien/Holocène, Québec, Canada) : enregistrement d'une régression forcée glacio-isostatique et de l'hydrodynamique d'un système fermé contrôlé par le vent
No full textIn this study, a certain number of continental enclosed basins including several depositional systems such as lakes, inland seas or lagoons have been grouped in a new sort of sedimentary system referred to as Wind driven Water Body. To characterize the sedimentary evolution and record of a WWB basin, an integrated sedimentological study has been carried out on the quaternary Saint-Jean basin (Québec, Canada) based on field onshore geology and offshore geophysics (CHIRP 2D).At the system-tract scale, the glacial to paraglacial sedimentation and the glacio-isostatic rebound controlled at first-order the lithofacies succession and large-scale architectures to generate an original Falling Stage System Tract (FSST). Within this FSST, since 8.5 cal. ka BP a WWB related sedimentary evolution overprinted the glacial to paraglacial evolution. This expressed in the form of the emplacement of an important coastal dynamics, occasionally accompanied by a lake-scale hydrodynamics at the origins of bottom currents during strong wind to storm events.Finally, the sedimentological analysis of the Saint-Jean basin brought numerous interpretations related to (1) the sedimentary evolution of WWB systems and (2) deglaciation sequences in previously glaciated domains. In addition, this work supplements the regional quaternary framework concerning the latest deglaciation evolution in southeast Quebec.Dans ce travail de thèse, certaines étendues d’eaux continentales regroupant plusieurs types de système de dépôt comme les lacs, mers intérieures et lagunes ont été regroupées au sein d'un nouveau groupe de système sédimentaire mentionnés sous l'appellation de Wind-driven Water Body (WWB).Afin de caractériser l'évolution et l'enregistrement sédimentaire d'un exemple de WWB, une étude sédimentologique intégrée du bassin quaternaire du Lac Saint-Jean (Québec, Canada) a été menée à partir d'une approche intégrant géologie de terrain et imagerie géophysique très haute résolution (CHIRP 2D). A l'échelle du cortège sédimentaire, le régime glaciaire à paraglaciaire de la sédimentation et le rebond glacio-isostatique ont contrôlé au premier ordre, à la fois la succession lithologique et les architectures grandes échelles du bassin pour générer un Cortège de Régression Forcée (CRF) atypique. Au sein de ce cortège de régression forcée fini-glaciaire, une dynamique de système WWB s'est progressivement affirmée à partir de 8,5 cal. ka BP. Elle s'est exprimée par la mise en place d'une dynamique littorale importante occasionnellement associée à une circulation interne générant des courants de fonds lors d'épisodes de vents forts.Finalement, l'analyse sédimentologique du bassin du Lac Saint-Jean a permis de dégager plusieurs interprétations ayant attrait (1) à l'évolution des systèmes WWB et (2) aux séquences de déglaciation en domaine précédemment englacé. De plus, ce travail représente une contribution à l'échelle régionale pour les modalités de la dernière déglaciation du Sud-Est du Québec
