Gestural patterns for the detection of autism in children
No full textEl autismo es uno de los trastornos de desarrollo más frecuentes y su prevalencia va en aumento. En México se estima que 1 de cada 115 niños tiene autismo. El diagnóstico del autismo es una tarea compleja, tardada y subjetiva, se basa en el auto-reporte y la observación de comportamientos. En los últimos años se han realizado investigaciones para encontrar marcadores bio-conductuales computacionales del autismo –un marcador bio-conductual computacional es una característica del autismo que se puede identificar por herramientas computacionales-. En particular se ha encontrado que la fuerza que usan los niños con autismo al jugar en una tableta es diferente a la fuerza que usan los niños neurotípicos. Sin embargo, los gestos realizados en una tableta rígida no brindan información suficiente para evaluar la fuerza que se usa. Las superficies elásticas representan una mejor oportunidad que las tabletas para evaluar aspectos relacionados con la fuerza. En esta tesis se propone la identificación del autismo en niños mediante el análisis de los gestos que realizan al usar una superficie elástica. Durante esta tesis se realizó un estudio en sitio donde participaron 46 niños neurotípicos y 26 niños con autismo. Todos los niños realizaron 7 actividades en una superficie elástica llamada Música Flexible, la cual es una superficie elástica que permite a los niños con autismo crear música y practicar patrones de movimiento. Para analizar los gestos que realizan los niños y evaluar si podemos distinguir autismo, se utilizaron técnicas de aprendizaje de máquina y se realizaron 3 experimentos. Los resultados indican que es posible distinguir entre niños con autismo de niños neurotípicos con una precisión de 97.2 % y una sensibilidad de 94.6%, utilizando la fuerza como variable de control cuando interactúan con una superficie elástica. Un análisis de los patrones gestuales de los niños con autismo al interactuar con una superficie elástica reveló que realizan gestos más pequeños, más angostos y más duraderos. Esto implica que los niños con autismo realizan menos gestos y usan menos fuerza que los niños neurotípicos.Currently, autism is one of the most frequent developmental disorders and its prevalence is increasing. In México 1 out of 155 children has autism. Etiology of autism is multifactorial and yet to be completely determined, consequently there is no cure for autism. Detection, the earliest the better, and subsequent remedial therapies is the only option. However, detection of autism is time-consuming, based on self-reporting and behavioral observation. As a consequence, the detection of autism is highly subjective. In recent years, research has been conducted to uncover the computational bio-behavioral markers associated to autism. A computational bio-behavioral marker is a behavioral feature able to be identified by computational tools. In particular, it has been found that children with autism use a different amount of force than neurotypical children when playing games with a tablet. However, a tablet using a rigid display can hardly uncover the amount of force its users use when manipulating its interface, making elastic surfaces a more appropriate technology to evaluate aspects related to force. In this work, we hypothesize that autism can be detected by analyzing the gestures used by children when interacting with an elastic surface. We conducted a deployment study where 46 neurotypical children and 26 children with autism used an elastic surface called Bendable Sound. Bendable Sound is a spandex fabric that allows children with autism to create music and practice movement patterns. We conducted 3 experiments analyzing our data by participant, gesture, and activity. We were able to distinguish between neurotypical and autistic children with 97.2% precision and 94.6 recall using only the interaction with an elastic surface as diagnostic tool. An analysis of the gestural movement patterns of children with autism shows that they tend to do smaller, narrower and slower gestures than neurotypicals. This implies that children with autism practiced fewer gestures and used less force than neurotypicals. This encouraging result seem to indicate that automated detection of autism is feasible
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
