Accessible Human Computer Interaction: Video Games and Assisted Living for Persons with Severe Disabilities
Full text linkAccessible Human Computer Interaction is a very wide area of study, which covers many topics and addresses several interesting problems; but there is a common goal that researchers of this field usually share: to use technology for improving the quality of life of persons with disabilities. In fact, this thesis stems from the will of helping persons with disabilities in different moments of their lives (i.e., during their childhood and in their adult age), by using different interactive technologies. In particular, this document explores two challenges: first, the problem that children with motor disabilities face as they cannot access dynamic video games as their normally developing peers do, leading them to reduced participation at leisure and playful educational activities, and finally to a potential social exclusion. The second challenge is faced by professional caregivers that work with adults motor and cognitively disabled, within assisted living facilities. Such caregivers need to effectively monitor the people under their care, as well as to be alerted of potentially hazardous situations that happen to these persons while they are alone. This thesis contributes to the improvement of the quality of life of persons with motor and cognitive disabilities, by supporting them in specific situations through different moments of their lives: in their childhood, by allowing them to play dynamic video games; and in their adulthood while they live and are cared by caregivers in assisted living facilities. Moreover, the research presented in this document constitutes a potentially valuable contribution to bring together the technical capabilities of engineers and HCI researchers, with the experience and knowledge of healthcare professionals that work daily with persons with disabilitie
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
Supporting Caregivers in Assisted Living Facilities for Persons with Disabilities: a User Study
Full text linkResearch activities on designing healthcare support systems in the field of ambient assisted living are mainly focused on addressing two problems: improving the quality of life for people in their own homes, especially the elderly, and supporting nurses and physicians in hospitals. However, few papers focus on designing specific systems for supporting caregivers that work with persons with disabilities in the context of assisted living facilities (ALFs). This paper intends to contribute to filling this gap and presents a series of guidelines for designing systems that could effectively support caregivers in tasks such as monitoring ALF inhabitants, attending to their assistance requests and managing notes and reminders regarding daily activities. These design guidelines derive from the qualitative analysis of a comprehensive user study, carried out in northern Italy, of three focus groups conducted with a total of 30 caregivers in three different ALFs for persons with physical and cognitive disabilities
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
Template-based ontology population for Smart Environments configuration
Full text linkSmart Environment is one of several domains in which Semantic Web technologies are applied nowadays. Ontologies, in particular, are used as core modeling languages for representing devices, systems and environments. Developing such ontologies, that typically involve several device descriptions (individuals) and related information, i.e., individuals of classes contributing to the device model, is often done by a manual, time consuming, and error-prone approach. Flexible and semi-automatic tools are therefore needed to enhance ontology population and to enable end-users to fruitfully configure their Smart Environments without the intervention of an ontology expert. This paper presents a template based approach, which increases accuracy, ease of use, and time-effectiveness of the ontology population process by reducing the amount of user-given information of about an order of magnitude, with respect to the fully manual approach. User-required information only pertains device features (e.g., name, location, etc.) and never implies knowledge of Semantic Web technologies, thus enabling end-user configuration of smart homes and buildings. Experimental results with a prototypical implementation confirm the viability of the approach on a real-world use cas
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
