Civic participation powered by Ethereum: A proposal
No full textIn the last decade, ICT infrastructures for smart cities have become a reality and the number of projects affecting citizens' lives is growing. In particular, the technology supporting civic participation is mature, although many systems do not reach the needed critical mass, as they are not able to capture the interest of their intended target. To overcome this difficulty, we describe a proposal for encouraging citizens' participation by a reward mechanism based on a civic currency, powered by blockchain tokens, used to recognize civic engagement.
This paper briefly sketches the main features of the system and discusses the development of its proof-of-concept in the context of a university course following an agile process, highlighting the lessons so learned
Enlisting Students in Gamifying Software Testing Education: Results and Key Insights
No full textGamification aims to enhance motivation for a variety of routine tasks by incorporating game elements, such as scoring. In educational settings, students are often the players, and gamification can create a more engaging learning environment that motivates them to achieve academic success. In this paper, we describe an experimental software engineering course where we asked students enrolled in a Master's degree program in Computer Science to play the role of game designers and develop software prototypes for the gamification of software testing education. We outline and compare their three proposals to gamify learning in software testing, which reflect team members' diverse interests and inclinations. As a result, the proposals vary in nature, ranging from a gamified standard web application delivering exercises to a fully-fledged game. User testing provided a preliminary evaluation of their playability. Our lessons learned can guide other academics in designing similar assignments for software engineering students to develop gamification prototypes
OT cyber security frameworks comparison tool (CSFCTool)
No full textThis paper proposes a holistic cybersecurity online tool to support implementation activities of the “National Framework for Cybersecurity & Data Protection”, one of its contextualizations, as well as the fifteen “Essential Cybersecurity Controls”. It also aims at promoting its wide dissemination by SMEs. All the regulations, standards and national/international laws mentioned as “Informative References” for each Subcategory in the Framework Core are, in fact, made available through a web application where they can be consulted with a few clicks, guiding even less experienced users in the creation of their cybersecurity compliance projects. The research and analysis activities conducted with a systematic, global and conceptual approach - consistent with the original document - have been aimed at highlighting the substantial differences between IT/OT cybersecurity requirements in order to increase, through a comparative analysis, the cyber resilience of national critical infrastructures. Meanwhile, since an important step towards cyberspace security is a global increase in the level of cyber risk awareness, the tool aims to be used for education and training programs too, both at the corporate and academic levels, in order to bridge the skills gap in the job market between job seekers and employers. For this purpose, some of the main reference standards used for auditing, vulnerability assessment and risk management activities have been included
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
