Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Retours d'expérience sur la conception centrée valeur de Cocoon (vers des arbres de vie)
Full text linkCette thèse porte sur la Conception Centrée Valeur (CCV) proposé par Gilbert Cockton dans le but d'aller au-delà de l'utilisabilité dans les systèmes interactifs. L'auteur propose un canevas pour la mise en oeuvre de la CCV. Cependant, les opérationnalisations restent partielles et sont réalisées par lui-même, d'où un manque de recul de la communauté vis-à-vis de la méthode. La thèse relate la conception centrée valeur de Cocoon, un système d'information mobile et sensible au contexte. Elle apporte des contributions à la fois sur les plans conceptuel et méthodologique. D'un point de vue conceptuel, elle introduit la taxonomie PIPE (Personnelle, Impersonnelle, Pérenne, Éphémère) pour la caractérisation de l'information. En outre, elle montre que les systèmes existants ne couvrent pas PIPE : ils sont surtout focalisés sur les informations impersonnelles. Alors, la thèse propose le concept d'arbre de vie et Cocoon. D'un point de vue méthodologique, la thèse apporte une compréhension meilleure de la notion de valeur. En outre, elle fournit un retour d'expérience sur la CCV accompagné de remarques et recommandations pour des mises en oeuvres futures plus performantes. Enfin, elle propose un canevas pour la construction des cartes de valeur et une stratégie pour l'estimation de la valeur.The thesis deals with Worth Centered Design (WCD) introduced by Gilbert Cockton. The author also introduced a framework aimed to support the WCD operationalization. However, this framework has been operationalized only partially until now and by Gilbert Cockton himself. The thesis relates our WCD experience with Cocoon, a mobile and context-aware information system. The thesis contributions are both conceptual and methodological. From a conceptual point of view, we introduce the PIPE (Personal, Impersonal, Perennial, Ephemeral) taxonomy for information characterization and show that existing systems only partially covers the PIPE information space: they focus on impersonal information. This notice motivated us to propose the life tree concept and Cocoon. From a methodological point of view, we offer a feedback to the community on an interesting concept method as well as recommendations for more efficient operationalizations. In addition, we introduce a framework for worth maps construction and a strategy for worth assessment.SAVOIE-SCD - Bib.électronique (730659901) / SudocGRENOBLE1/INP-Bib.électronique (384210012) / SudocGRENOBLE2/3-Bib.électronique (384219901) / SudocSudocFranceF
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
