Interactive reflexive and embodied exploration of sound qualities with BeSound
No full textThe embodied and reflexive interaction paradigms separately proved to be eective for learning music in childhood. However, nowadays, there is a scarcity of research addressing the joined adoption of these paradigms, both from a theoretical and a technological point of view. BeSound supports children to explore - by means of their own body - rhythm, melody, and harmony and to creatively combine them together. Firstly, the child is engaged in a game in which she has to mimic the movement of the characters of stories BeSound tells her; then she can ad-lib a music dialogue with the characters. Each character was previously associated with a component of Laban's Eort and it was described through a set of whole-body movement features. These features are automatically detected, analysed, and used to control the music response of BeSound
Designing multimodal interactive systems using EyesWeb XMI
No full textThis paper introduces the EyesWeb XMI platform (for eXtended Multimodal Interaction) as a tool for fast prototyping of multimodal systems, including interconnection of multiple smart devices, e.g., smartphones. EyesWeb is endowed with a visual programming language enabling users to compose modules into applications. Modules are collected in several libraries and include support of many input devices (e.g., video, audio, motion capture, accelerometers, and physiological sensors), output devices (e.g., video, audio, 2D and 3D graphics), and synchronized multimodal data processing. Specific libraries are devoted to real-time analysis of nonverbal expressive motor and social behavior. The EyesWeb platform encompasses further tools such EyesWeb Mobile supporting the development of customized Graphical User Interfaces for specific classes of users. The paper will review the EyesWeb platform and its components, starting from its historical origins, and with a particular focus on the Human-Computer Interaction aspects

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
Towards a Multimodal Repository of Expressive Movement Qualities in Dance
No full textIn this paper, we present a new multimodal repository for the analysis of expressive movement qualities in dance. First, we discuss guidelines and methodology that we applied to create this repository. Next, the technical setup of recordings and the platform for capturing the synchronized audio-visual, physiological, and motion capture data are presented. The initial content of the repository consists of about 90 minutes of short dance performances movement sequences, and improvisations performed by four dancers, displaying three expressive qualities: Fluidity, Impulsivity, and Rigidity
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
