Computational modeling of user activity in full-body interaction environments for ASC children: multimodal analysis of social interaction behaviors through psychophysiology, system activity, video coding, questionnaires, and body cues
No full textFull-body Interaction experiences based on Mixed Reality (MR) systems are already playing an important role in encouraging socialization behaviors in children with Autism Spectrum Condition (ASC), as seen in the state of the art of this thesis. However, the data from these systems is multimodal in nature and complex to analyze. Fusion and analysis of this data is crucial to achieve a complete understanding of how these resources interact with each other. In this PhD Thesis, given the characteristics of full-body interaction, we developed new multimodal data gathering and evaluation techniques to better understand the effectiveness of the experience developed in our Full-body Interaction Lab (FuBIntLab) called Lands of Fog. This is a large-scale MR, full-body interaction environment, which allows two children to play face-to-face and explore the physical and virtual worlds simultaneously. Specifically, we developed an experimental setup for comparing Lands of Fog with a control condition based on LEGO construction toys, which includes: recording psychophysiological measures synchronized with other data sources such as observed overt behaviors and system logs of game events. In order to capture accurate psychophysiological data, we developed a wearable that is child-friendly and robust to movement artifacts in the context of ambulatory full-body interaction. In order to integrate observed overt behaviors with other data sources, we designed and developed a novel video coding protocol and an adapted coding grid conceived for Social Interaction Behaviors (SIBs) in ASC children. Using a repeated measure design, we collected data from seventy-two children (36 ASC/non-ASC dyads) from the city of Barcelona, with ages between 8-12 years old (N = 12 female, N = 60 male). Data from these trials has been organized into a public database and processed based on a semi-automatic software pipeline developed within this project. Based on this data we developed three different computational models for modelling SIBs in children with ASC during Lands of Fog sessions, compared to LEGO sessions. The results of this research support the idea that full-body interaction MR environments are capable of fostering SIBs in children with ASC with similar success as the LEGO setting, with an added advantage of being more flexible. Findings reported here shed new light on developing a tool that is mediating, guiding, and supporting the progress of the children in terms of practicing SIBs and providing structure and assistance to therapists.Programa de doctorat en Tecnologies de la Informació i les Comunicacion

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
