NADIA - NAvigation for DIsability Applications
No full textIl Progetto Nadia (NAvigation for Disability Applications), finanziato dall'Agenzia Spaziale Italiana ed affidato a un team composto da industrie, università e associazioni d'utenza, ha l'obiettivo di sviluppare un sistema prototipale che consenta agli utenti del progetto (disabili motori, ipo/non vedenti) una maggiore autonomia e una più sicura mobilità in ambito urbano, tramite l'utilizzo di tecniche di radionavigazione satellitare.
La presentazione descriverà le attività ingegneristiche finora effettuate e in particolare a partire dalla definizione dei requisiti utente, la progettazione del sistema e lo sviluppo dei suoi elementi critici (fra cui specifiche interfacce utente, algoritmi di comunicazione per migliorare la sicurezza, detezione di ostacoli e navigazione indoor
The NADIA Terminal User Interface for People with Motor Disabilities
No full textIn this paper, a user terminal interface is described realizing an application allowing autonomous and safe mobility of people on a wheelchair. The application has been developed in the framework of the NADIA research project, funded and promoted by the Italian Space Agency (ASI) and implemented by Thales Alenia Space Italia with the collaboration of a mixed team of companies, university and user associations. The project has brought to the realization of a system exploiting the combined use of satellite navigation technologies based on GPS, EGNOS and augmentation signals, of hybridized technologies and of specific and user-oriented services implemented by terrestrial infrastructures. The user terminal selected is a consumer laptop, due to its flexibility, processing power, possibility of connection to other devices needed for the application. The user terminal has been made suitable to provide NADIA services also to wheelchair users presenting different kinds and degrees of upper limb disabilities, by means of a proper hardware solution overcoming limitations of existing technical aids for PC accessibility, not intended to be used in an autonomous mobility scenario. Also thanks to a proper control scheme of the application implemented by the terminal software, users may be provided with NADIA services by means of commercially available switch sensors specifically devoted to exploit user-specific residual abilities. The development of the solution has been constantly guided by hints and feedbacks from user associations, partners in the project. The NADIA prototype system has been successfully tested in several occasions by wheelchair users with upper limb disabilities
A step forward towards increasing the mobility and participation of people with disabilities utilizing Satellite Navigation Technology Applications
No full textLarge groups of the population in Europe encounter significant difficulties in taking part in everyday life due to their functional limitations. The NADIA (NAvigation for DIsability Applications) Project, funded and promoted by the Italian Space Agency (ASI) and implemented by Thales Alenia Space Italia with the collaboration of a mixed team of companies, university and user associations, has made concrete steps forward in demonstrating that satellite navigation applications can have an important role in facilitating the mobility of people with disabilities. This paper describes not only some basic features of the system, but looks at how they are related to the process of defining user needs and requirements, highlighting the role of end users and of professional users of Assistive Technology (AT)
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
