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
The Iron age ceramic in the Lower Aragon (Spain) during the Middle and Late Iberian : production, distribution, uses
No full textLa céramique ibérique à pâte claire et décorée de motifs peints en rouge fut fabriquée par les populations ibériques entre le VIème et la fin du Ier s. av. J.-C. Au IIIème s. av. J.-C., les décors peints de ces céramiques s’enrichirent avec une iconographie associant motifs géométriques, végétaux et figurés, et qui permis de distinguer plusieurs ensembles régionaux, dont le Bas-Aragon. Le Cabezo de Alcalá à Azaila donna son nom au style régional en raison de la richesse du matériel qui y fut découvert. Depuis, d’autres sites ont livré du matériel caractéristique de ce phénomène, sans que les éléments de définition n’aient intégré des aspects autres que l’iconographie.Dans cette étude, la notion de style est mise de côté en faveur de celle de faciès céramique, afin d’intégrer plusieurs aspects d’une étude céramique : la technique, la technologie, la morphologie et l’iconographie. En renouvelant l’approche de ce matériel, il est possible de proposer une actualisation de la définition du faciès céramique du Bas-Aragon entre le IIIème et le Ier s. av. J.-C. Des lots de mobiliers issus de différents contextes permettent d’analyser ces aspects depuis des perspectives différentes. L’atelier de production de céramique du Mas de Moreno à Foz-Calanda est le point de départ de toutes nos observations. Le matériel issu de contextes domestiques permet d’élargir la réflexion à l’échelle régionale avec les sites d’Azaila, d’Alloza, d’Alcorisa et d’Oliete.Certaines spécificités iconographiques permettent d’identifier des particularismes locaux ou régionaux. Un nouveau système de classification adapté à l’étude des déchets de production d’un atelier de poterie a été mis en place en ne retenant que les attributs morphométriques. Toutes les étapes de la chaîne opératoire sont analysées. Différents dossiers, qui portent à la fois sur les acteurs de la production et sur les utilisateurs, permettent d’aborder les dynamiques de constitution, d’évolution et les modalités de distribution.The light-paste and red painted Iberian ceramics was made by Iberian populations between the 6th and the end of the 1st century B.C. During the 3rd century B.C., those ceramics were enriched with geometric, vegetal and figurative patterns, which made it possible to distinguished several regional groups, including the Lower-Aragon. According to the important ceramics discovered in the Cabezo de Alcalá (Azaila), the name of the site was given to the regional style. Since then, other sites have delivered material characteristic of this phenomenon, but the iconography remained the only defining element. In this study, the notion of style will be set aside in favour of “faciès céramique”, in order to integrate different aspects from a ceramic study: technic, technology, morphology and iconography. By renewing this material approach, it is possible to submit an update of the definition of the “faciès céramique” of the Lower-Aragon between the 3rd and the 1st centuries B.C. Some material sets chosen in different contexts make it possible to analyse these aspects from different perspectives. The Mas de Moreno (Foz-Calanda) workshop is the start of our investigation. The material from domestic contexts enable to extend the reflection on a regional scale with the sites of Azaila, Alloza, Alcorisa and Oliete. Some iconographic specificities enable to identify local or regional particularities. A new classification system adapted to the study of production waste from a pottery workshop was implemented by retaining only the morphometric attributes. All the stages of the “chaîne opératoire” are analyzed. Various files, which relate both to production players and to users, open discussions about the dynamics of constitution, development and distribution methods
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
