Workshop “Il parco fluviale del fiume Irno”
No full textL’edizione 2015 del Seminario Internazionale Uniscape En-Route, dal titolo “Recovering River Landscapes”, ha previsto anche due design workshop di una giornata in cui i ricercatori e professionisti partecipanti hanno potuto affrontare il tema del paesaggio fluviale in due contesti molto diversi seppur poco distanti l’uno dall’altro. Un gruppo, coordinato dal prof. Vito Cappiello, si è infatti interessato del bacino del Sarno, un’area piuttosto famosa per frequenti crisi idrauliche ed idrogeologiche che presenta rilevanti valori ambientali originari ma anche fortissimi elementi di degrado ecologico e paesaggistico. Un altro gruppo, coordinato dallo scrivente, ha lavorato sulla valle del fiume Irno, ambito mediaticamente meno rilevante eppure in grado di offrire agli abitanti dei comuni attraversati un paesaggio ricco di valore e che costituisce un esempio unico in Campania di parco fluviale urbano effettivamente attivo

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
Radon migration in the soils of the Irno Valley (Southern Italy) inferred from radioactive disequilibrium
No full textRadon migration along vertical profiles in the soils of Irno River alluvial Valley (Southern Italy) was studied using radioactive disequilibrium between 226 Ra and 210 Pb. Fractional Radon loss, migration length, diffusion and emanation coefficient and Radon flux density were determined. Our results are in agreement with a migra- tion model by simple diffusion. The migration parameters are within typical values, except the Radon flux density, which is about one order of magnitude higher than the values reported in literature. The values of fractional Radon loss are sensitive to changes in the physical properties of the soil.JCR Journalope
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
Exploring a social-aware WebRTC-based P2P architecture for live video streaming
No full textIn the present work a feasibility study of a novel peer-to-peer architecture for live video streaming is proposed. It leverages both recent web technologies for peer implementation and overlay management, and the use of online social networks as integral part of the architecture itself.
The key points of the architecture are: (1) the use of WebRTC to setup and manage a P2P overlay, and to deliver audio/video streams; (2) the implementation of P2P clients as HTML5/Javascript web applications, without involving other centralized entities acting as servers, according to a nearly serverless model; (3) the use of online social networks to retrieve user information and relationships between them, in order to improve overlay and stream management, and as a place to announce their setup and broadcasting, and to increase the audience; (4) the use of social networks to implement the WebRTC signaling.
In this paper, after a brief excursus of the involved technologies, the proposed architecture will be introduced, and a first prototype will be presented with the aim of demonstrating the feasibility of the project. The authors will also introduce the elements of the architecture on which future efforts for subsequent enhancements and extensions will be focused
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
