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
Les productions céramiques en Sardaigne au IVe millénaire av. J.-C. Nouvelles données sur le village de Su Coddu-Canelles (Selargius, Cagliari)
Get PDFCette étude fait partie du projet de recherche de l’Université de Sassari « Archéologie des habitats préhistoriques sardes », dirigé par Maria Grazia Melis. Le but principal est la reconstitution du cadre environnemental et socio-économique des phases finales du Néolithique sarde et du début du Chalcolithique, caractérisé par les ultimes aspects du « phénomène » Ozieri. La première étape de la recherche a été consacrée à l’analyse typologique de la céramique dérivée d’Ozieri des IVe et IIIe millénaires av. J.-C., et a impliqué la réorganisation des données publiées, l’élaboration d’une sériation et d’une hypothèse de séquence culturelle. Par la suite, la fouille du village de Su Coddu-Canelles (Selargius, Cagliari) a permis l’acquisition de données primaires et de nouvelles datations 14C, qui confirment la séquence déterminée par l’analyse typologique. Enfin l’étude morpho-technologique de la production artisanale a montré son caractère « opportuniste » qui nous amène à une nouvelle vision de l’organisation de la production et de l’économie du village.This study is part of the research project directed by the University of Sassari and called “ Archaeology of Sardinian Prehistoric Settlements ”, under the supervision of Maria Grazia Melis. The main purpose is to reconstruct the environmental and socio-economic development of the Sardinian Neolithic and Early Copper Age final stages, typified by the final aspects of the Ozieri “phenomenon”. The first stage of research was dedicated to the typological analysis of ceramics derived from Ozieri and dating back to the IVth and IIIrd millennia B.C., which involved reorganizing published data, designing a seriation and a hypothetical cultural sequence. Thereafter, the excavation of Su-Coddu Canelles village (Selargius, Cagliari) enabled the acquisition of primary data and new 14C dating confirming the sequence determined by typological analysis. Lastly, the morpho-technological study of craft production has shown its « opportunistic » nature, which brings up a new perception of the production organization and the economic structure of the village
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
Notiziario. S’Elighe Entosu (Usini, prov. di Sassari)
No full textIl progetto pluriennale di ricerca intorno alla necropoli a domus de janas di S’Elighe Entosu, iniziato nel 2006 (D’ANNA A., MELIS M. G., TRAMONI P., S’Elighe Entosu (Usini, prov. di Sassari), RSP LVII, 2007, p. 468.) ad opera dell’Università di Sassari, sotto la direzione scientifica di Maria Grazia Melis, è stato portato avanti negli anni 2007 e 2008 con diverse campagne di scavo e ricognizione nel territorio comunale. Un’ulteriore fase di attività sul campo è prevista tra la primavera e l’estate del 2009. La ricerca è condotta con la collaborazione di un’équipe del Laboratoire méditerranéen de Préhistoire (Europe – Afrique) (UMR 6636, MMSH, Aix-en-Provence), diretta da A. D’Anna. Tale collaborazione si sviluppa in piena sinergia sia a livello teorico sul piano metodologico e dello scambio di competenze, sia a livello pratico nella produzione di dati primari e nell’elaborazione di quadri di riferimento per la conoscenza delle società preistoriche e protostoriche
