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

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
L'inconnu derrière la vague. Contribution à l'histoire des migrations polynésiennes en Mélanésie Australe : études exploratoires des variations phénotypiques sur 3000 ans d'histoire
No full textSeveral localities in Southern Melanesia display human societies with Polynesian linguistic and cultural features. They are defined as Polynesian Outliers because they are located outside the Polynesian Triangle. Their formation is interpreted as resulting from the settlement of individuals originating from Polynesia. Archaeological and bio-anthropological research, however, does not identify cultural and biological components related to Polynesian human groups in their sequences. The times, places, and settings of the introduction of Polynesian influences into the region thus remain to be defined. To this end, we analyzed the phenotype of 70 archaeological individuals from Vanuatu, New Caledonia, and Loyalty dated from 3000 to 150 BP. Different part of their skulls were analyzed to identify their population affinities, particularly with modern Polynesian populations. Then, we set out to reconstruct the parameters of migrations (directions, size of the groups involved, frequencies) in the framework of the mobilities practiced by the insular societies of the South Pacific. Our results combined with knowledge of the archaeological and funerary context of individuals, indicate the physical presence of individuals originating from Polynesia during the last millennium, including in localities that are not considered as Polynesian Outliers. We "meet" these individuals by reconstructing their biological identity (age, sex and health), but also their social identity (isolated or integrated), thanks to the analysis of other individuals surrounding them geographically and chronologically. Our results highlight phenomena of integration of women from Polynesia into local communities in southern Melanesia. Archaeological and oral tradition data allow us to put forward the hypothesis that this integration was achieved through matrimonial exchanges. These exchanges would have participated in the diffusion of Polynesian cultural characteristics over the generations while the Polynesian biological components would have diminished over time.Plusieurs localités de la Mélanésie australe présentent des sociétés humaines aux caractéristiques linguistiques et culturelles polynésiennes. Elles sont définies comme des Enclaves Polynésiennes car elles sont situées en dehors du Triangle polynésien. Leur formation est interprétée comme résultant de l'installation d'individus originaires de Polynésie. Les recherches archéologiques et bio-anthropologiques n'identifient pourtant pas de composantes culturelles et biologiques relatives à des groupes humains polynésiens dans leurs séquences. Les moments, lieux et cadres de l'introduction des influences polynésiennes dans la région restent donc à définir. C'est dans ce but que nous avons analysé le phénotype de 70 individus archéologiques du Vanuatu, de Nouvelle-Calédonie et des Loyauté datés de 3000 à 150 BP. Différentes portions de leur tête osseuse ont été analysées afin d'identifier leurs affinités populationnelles, notamment avec les populations polynésiennes modernes. Puis, nous nous sommes attachés à reconstruire les paramètres de migrations (directions, taille des groupes impliqués, fréquences) dans le cadre particulier des mobilités pratiquées par les sociétés insulaires du Pacifique Sud. Nos résultats combinés aux connaissances sur le contexte archéologique et funéraire des individus indiquent la présence physique d'individus originaires de Polynésie au cours du dernier millénaire, y compris dans des localités qui ne sont pas considérées comme des Enclaves Polynésiennes. Nous « rencontrons » ces individus par la reconstruction de leur identité individuelle (âge, sexe et santé), mais aussi sociale (isolé ou intégré), grâce à l'analyse des autres individus les entourant géographiquement et chronologiquement. Nos résultats mettent en évidence des phénomènes d'intégration de femmes originaires de Polynésie au sein des communautés locales de Mélanésie australe. Les données de l'archéologie et de la tradition orale nous permettent d'avancer l'hypothèse que cette intégration s'est réalisée dans le cadre d'échanges matrimoniaux. Ces échanges auraient participé à la diffusion de caractéristiques culturelles polynésiennes au fil des générations tandis que les composantes biologiques polynésiennes auraient diminué avec le temps
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
