No full textThree years of teaching using collaborative tools : patterns and lessons learned
Full text linkThe author has taught computer science (Programming 101 and Operating Systems 101) for about fifteen years. He introduced the use of a student-collaborated wiki website for his courses about ten years ago. Then, three years ago, he also began extensively using a collaborative editor (Gobby) in classroom, to let students actively participate during lessons. This paper describes the author’s course “workflow”, summarizes tools (wiki and collaborative editor) functionalities, collects some context pattern and tries to draw a few conclusions (lessons learned) about the course methodology
PUNTOnet Prototypes: Innovative Urban Services Supporting Healthy and Sustainable Behaviours
No full textThis paper describes the objectives and the outputs of a University- Industry research project, with the aim to innovate household waste collection and other urban services, through the design and development of prototype multifunctional station, in line with the principles of circular economy. It begins by presenting the potential of ordinary garbage bins to become an urban interface with the support of technology. In order to meet European recycling targets and optimize operational costs, trash containers need to achieve a greater intelligence, recognize users’ identity, record the type and the quantity of delivered waste. The specialisation and improvement of such awidespread service give the possibility to reinvent collection points as a smart and sensing zones, sharing their sophisticated technology equipment with other urban facilities.
The essay then looks at possible additional services for the city and displays the research group proposal dealing with mobility infrastructure. Finally, the paper closes with the description of the content of an experimental urban dashboard gathering all data coming fromthe prototypes, developed by the local utility group for the demo site, a small smart city of 10 000 inhabitants.This paper describes the objectives and the outputs of a University-Industry research project, with the aim to innovate household waste collection and other urban services, through the design and development of prototype multifunctional station, in line with the principles of circular economy.

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
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
