Perspectives and challenges in e-learning: towards natural interaction paradigms
Full text linkThe role of Information and Communication Technologies (ICTs) in educational
development has been world-wide recognized as a priority in order ‘‘to reinforce academic
development, to widen access, to attain universal scope and to extend knowledge, as well as to
facilitate education throughout life’’ (Council of Ministers of Education, Canada, Report of
the Canadian Delegation to the UNESCO World Conference on Higher Education, Paris,
October 5–9, 1998. http://www.cmec.ca/international/unesco WCHE98report.en.pdf). As a
consequence, developments in ICTs have had a significant impact on conventional higher
education, as the university of the 21st century takes shape. By analyzing traditional learning
models as opposed to new e-learning paradigms, this paper provides a global overview on
future learning systems, from bothtech nology- and user-centered perspectives. In particular,
the visual component of the e-learning experience is emphasized as a significant feature for
effective content development and delivery, while the adoption of new interaction paradigms
based on multi-dimensional metaphors and perceptive interfaces is presented as a promising
direction towards more natural and effective learning experiences

Artificial Vision in Road Vehicles
No full textThe last few decades have witnessed the birth and growth of a new sensibility to transportation efficiency. In particular the need for efficient and improved people and goods mobility has pushed researchers to address the problem of intelligent transportation systems. This paper surveys the most advanced approaches to (partial) customization of the road following task, using on-board systems based on artificial vision. The functionalities of lane detection, obstacle detection and pedestrian detection are described and classified, and their possible application in future road vehicles is discussed
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
