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

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
Acquisition et apprentissage de la phonologie anglaise par les francophones : le rôle des segments et suprasegments
No full textResearchers increasingly highlight the crucial role of prosody in communication, speech comprehensibility, and the detection of a foreign accent. Thus, the learning and teaching of English as a foreign language would benefit from prioritising the suprasegmental, or prosodic, features (i.e., stress, rhythm, and intonation), rather than the segmental features (i.e., consonants and vowels) as many teachers tend to do, all the more so as prosodic errors often have a more detrimental effect than segmental errors. The present doctoral thesis starts from the hypothesis that French-speaking learners of English could improve their oral skills (production and perception) more if they were primarily taught the prosodic characteristics of the target language, rather than putting the segments in the foreground. Our experimental study compares the impact of a “prosody-based” teaching approach with that of a “segment-based” approach on non-beginner French learners of English. Although the two teaching methods enabled the participants to improve their L2 production and perception skills, compared with a non-treated control group, neither of the two methods enabled them to improve their oral skills more than the other, suggesting that it is important to include segmental and suprasegmental aspects alike in the teaching of English as a foreign language.De plus en plus de chercheurs s'accordent à dire que la prosodie a un rôle crucial dans la communication, la compréhensibilité du discours et la détection d'un accent étranger. L'apprentissage et l'enseignement de l'anglais langue étrangère bénéficieraient ainsi à mettre au premier plan les traits suprasegmentaux, ou prosodiques (accent, rythme et intonation), plutôt que les traits segmentaux (consonnes et voyelles) comme le font beaucoup d'enseignants, d'autant que les erreurs prosodiques ont souvent un effet plus néfaste que les erreurs segmentales. Cette thèse de doctorat part de l'hypothèse que les francophones apprenant l'anglais pourraient davantage améliorer leurs capacités à l'oral (production et perception) si on leur enseignait avant tout les caractéristiques prosodiques de la langue cible, plutôt que de mettre en avant les segments. Notre étude expérimentale compare ainsi l'impact d'une approche « prosodique » avec l'impact d'une approche « segmentale » sur des apprenants français non-débutants. Bien que les deux méthodes d'enseignement aient permis aux participants de s'améliorer en production et perception L2, en comparaison avec un groupe de contrôle n'ayant pas reçu de cours, aucune des deux méthodes ne leur a permis d'améliorer leurs capacités à l'oral davantage que l'autre, ce qui montre l'importance tout aussi forte d'inclure les aspects segmentaux que suprasegmentaux dans l'enseignement de l'anglais langue étrangère
