Introduction
No full textPreface to a collection of scholarly research originatingfrom a workshop entitled “Multimodal Perspectives on Language Teaching and Research” held in May 2015 at the University of Pisa. The aim of the workshop was to explore multimodality from both analytical and practical perspectives, with contributions grounded in discourse analysis, conversation analysis, pragmatics, and corpus linguistics, as well as applications for teaching and learning. The workshop was sponsored by the Department of Philology, Literature, and Linguistics, and organised by the Corpus Research Unit of the University of Pisa Language Centr
Chapter Three: A multimodal analysis of interaction in academic lectures: A case study
No full textAcademic lectures have long been the hallmark of higher education, representing an oral instructional channel through which knowledge is transmitted from experts to novices. Studies dedicated to lecture discourse have highlighted numerous linguistic features used by lecturers not only to explain disciplinary concepts, but also to interact with students on an interpersonal level in order to facilitate learning. Among the latter are questions, comprehension checks, and imperatives, as well as language features linked to informality, including idiomatic expressions and humour. However, relatively little research has been done on the contribution of other semiotic resources beyond the verbal mode to construct interpersonal meanings between lecturers and students in the context of higher education.
Using a case-study approach, this chapter aims to shed light on the interplay between verbal and non-verbal modes during interpersonal episodes in an academic lecture, and how this may work towards enhancing understanding. On the verbal level, the analysis focused on the lecturer’s use of interactional devices, i.e. comprehension checks, imperatives, idioms and puns. On the non-verbal level, the co-occurrence of prosodic stress, gaze direction, and hand/arm gesturing with interactional language were investigated. The data consist of the digital video recording and corresponding transcript of a political philosophy lecture available on Yale University’s Open Courses website. The multimodal annotation software ELAN (Wittenburg et al. 2006) was implemented to identify the co-occurrence of verbal and non-verbal elements during interpersonal episodes in which the lecturer engages with students in the audience. With particular reference to gesturing, the study adopted an analytical framework based on description (Querol-Julián 2011) and function (Kendon 2004; Weinberg et al. 2013). The multimodal analysis of interpersonal features in lecturer-audience interaction contributes to a better understanding of how verbal and non-verbal features can work synergistically to reinforce meanings, thus improving comprehension and promoting a learning-friendly classroom atmosphere
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

No full textDispelling 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
