Interactive Maps of Chorems Explaining Urban Contexts to Align Smart Community’s Actors
No full textThe actualization of the three pillars of the Open Government paradigm, namely transparency, participation and collaboration, motivates the importance for a smart city administration to share decisions with citizens to receive real support and legitimize the decisions made. A way to engage citizens is to make available government data as open. This allows achieving a higher transparency in decision-making that also fosters citizens to support the strategic objectives of the city and improve the individual and collective quality of life. The goal of this paper is to show the effectiveness of chorems as a communication and support tool for understanding the dynamic realities of a territory. When used to visually synthesize urban contexts, maps of chorems can produce a territorial schematic representation, which eliminates details not useful to the map comprehension, and emphasizes relevant information to enable decision makers, experts and ordinary citizens to share knowledge about complex phenomena occurring in urban areas. A use case is built, which describes how the urban heat island phenomenon and the factors involved in its development are analyzed through a set of chorems and operators. This phenomenon is invisible but typically present in most of the modern cities. It is composed of different urban elements present on the urban territory and its understanding implies technical and scientific knowledge not common among citizens and administrators. By visually interacting with chorems, it is possible support data manipulation by expert users, and data interpretation by citizens, thus aligning the different actors of a smart community towards a shared sustainability goal
Geo-education as a valuable support to children with learning difficulties
No full textIn recent years, the way some subjects are now taught has changed to provide students with a thorough understanding of the dynamics and interconnections in the world, with an increasing emphasis on geography. However, so far, little has been done to provide adequate learning tools to support such an important transformation, and particularly for children with learning difficulties. This paper proposes the integration of advanced geospatial technology into traditional interactive learning tools as a way to describe experiences that help students understand phenomena and improve their skills. The system is the result of a usability engineering process aimed at providing users with learning difficulties an effective learning experience, by iteratively analyzing their expectations and needs with respect to georeferenced content. The results were encouraging and showed that improved learning can actually be achieved using the system
The Italian solution for the cadastre of technological infrastructures
No full textThis paper aims at showing the implementation of the Italian cadastre of technological infrastructures, its maintenance and updating. SINFI (National Infrastructure Federated Information System) is the identified platform devoted to the coordination and management of national infrastructures in the framework of the broadband and ultra-broadband Italian strategy. Among its functions, it facilitates sharing of infrastructures, thanks to coordinated management of the under- and over-ground technological networks and related interventions; it also offers a single dashboard that efficiently manages and monitors all interventions. Previously, the need for such a platform was put in relation to the rational use of the underground and the implications onto the management of public land: consequently, even on the mobility infrastructures and transportation systems, as well as risks for people and manufactured goods, but also to prevent potential economic damages from accidental breakage of pipes and ducts. The increased awareness in terms of safety and civil protection has further expanded its importance, linking, for example, its availability to environmental issues (such as hydrogeological instability) to the context of critical infrastructure management (see Directive 2008/114 / EC) Last but not least, the availability of such a register is necessary to publicly check choices on sustainable development, according with the UN 2030 Agenda for Sustainable Development, signed in September 2015 by the Governments of 193 UN Member Countries, specifically with respect to the themes of Strategic Development Goals 9 (“Build Resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation”) and 11 (“Make cities and human settlements inclusive, safe, resilient and sustainable”). The paper aims at providing solid answers to a multiplicity of operators / stakeholders in this respect / application framework, thanks to the availability of a national information system specifically dedicated to the over- and under-ground network infrastructures - the SINFI1
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
