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
The multimodal expression of subordination in English
No full textÀ partir d'un corpus vidéo de conversation spontanée en anglais, notre travail de thèse s'attache à déterminer si plusieurs types syntaxiques de constructions subordonnées expriment le même degré d'intégration à leur environnement co-textuel, d'une perspective multimodale. La littérature syntaxique décrit les subordonnées comme des formes dépendantes, qui spécifient ou élaborent le contenu d'une autre proposition. En montrant que les constructions sous étude n'expriment pas une dépendance uniforme à leur environnement selon la façon dont les locuteurs utilisent les modalités prosodique et gestuelle pour exprimer plus ou moins de démarcation, les résultats en production comme en perception suggèrent d'une part que les appositives sont produites avec davantage de rupture que les autres types syntaxiques, et d'autre part que la création d'une rupture s'appuie majoritairement sur des moyens davantage prosodiques que gestuels.Based on a video recording of conversational British English and within the framework of Multimodal Discourse Analysis, this study tests whether three different syntactic types of subordinate structures are evenly integrated to their environment. Subordinate constructions have been described in syntax as dependent forms elaborating on primary elements of discourse. Beyond showing that subordinate constructions are not evenly dependent on their environment depending on how speakers use the prosodic and kinetic modalities to express greater (in)dependency, our results in production as in perception suggest on the one hand that appositive clauses show more break than the other syntactic types, and on the other hand that the creation of a break mainly relies on prosodic cues
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
Gestural correlates to the OVER AND OVER expression
No full textInternational audienceThis study identifies stable gestural correlates to the OVER AND OVER adverbial phrase in American English. This expression involves lexical iteration and adds aspectual information. Speakers have been shown to rely on co-verbal gestures to communicate aspectual information, along with lexical and grammatical means. However, most of the research has focused on hand gestures. Cyclic gestures have particularly been linked with meanings of motion, either physical or metaphorical, as well as continuity. We use video datasets of spoken American English belonging to the Distributed Little Red Hen Lab as part of the UCLA Library Newscape Archive. We determine which formal features participate in the expression of iteration, in a variety of articulators (hands, head, eyebrows)
Vocal and visual boundaries in speech: insights from spontaneous conversation
No full textInternational audienceIn this talk, I will give an overview of my work that looks specifically at the expression of boundaries in speech. I will refer to different groups of studies. First, a series of observational studies investigating the use of boundaries to signal parentheticals and appositive relative clauses in spontaneous speech (Lelandais & Ferré 2014; Lelandais & Ferré 2016; Lelandais 2020). Second, an experiment which investigates the role of prosody and gesture in the perception of boundaries in speech (Lelandais & Thiberge, submitted). Third, an ongoing exploratory study in which I propose an alternative view of coordination to that of traditional syntax, based on the presence or absence of boundaries. The goal of this project is to build a multiparameter framework that accounts for coordination in different interactional contexts. Finally, I will mention short-term developments and perspectives
