Insediamenti residenziali pubblici e rigenerazione urbana. L’arte nei quartieri Ater di Roma
No full textThe contemporary city, the outcome of metropolization’s processes, while retaining unchanged, indeed increasing, its role as a driver for the economic growth of the country, at the same time feeds phenomena of socioeconomic, spatial and ecological-environ- mental polarisation and fragility. In particular, public peripheries are characterised by increasing marginal conditions, which often do not allow the maintenance of adequate levels of urban welfare, well-being and
quality of life for the local communities. The urban regeneration strategy, which constitutes the main reference for the intervention in the public peripheries, aims at construction of the public city and enhancement of the common goods, on which re-establish the structure and the image of the neighborhoods, the quality of the environment and of the public spaces, and the sense of belonging to the places. In this per- spective, urban art can represent the driver for urban
regeneration virtuous processes, because it refers to participatory and emotional artistic expressions that involve heterogeneous spaces and objects, giving voice to the instances that emerge from the territories. Many European public peripheries over the last decade have been the focus of regeneration projects based on art and identity re-appropriation, in order to rethinking them as cultural centres and destinations of alternative tourist flows, which physically and symbolically reconnect them to the urban system and give it back prospects of equity and quality of life.
The paper illustrates two public art projects aimed at the regeneration of public peripheries in Rome: Big City Life in Tor Marancia and Sanba in San Basilio. Both, started in 2014 by cultural associations initiati- ve, have involved, also financially, public and priva- te stakeholders, and have provided a participatory path to share the project with the local community since the early phases of conception
Spazio pubblico, arte, identità. Per una strategia di rigenerazione urbana
No full textLa riflessione al centro del volume “Spazio pubblico, arte e identità. Per una strategia di rigenerazione urbana”, che fa proprio l’interrogativo su quali siano le modalità di interazione tra spazio pubblico e pratica artistica, si contestualizza in un processo di approfondimento e di confronto, a tutto campo e multiscalare, dal contesto internazionale a quello nazionale, sul ruolo imprescindibile dello spazio pubblico, e più in generale della città pubblica, quale componente strutturale delle strategie di rigenerazione urbana riferite, in particolar modo, a contesti urbani e territoriali connotati da una significativa compresenza di componenti del patrimonio culturale. Tale riflessione consente di mettere a fuoco alcuni nodi tematici, che si configurano come significativi ambiti di innovazione disciplinare, centrali negli obiettivi e nelle politiche urbane europee, che da anni rivestono un ruolo rilevante nelle attività di ricerca e di sperimentazione, di disseminazione e di formazione che il Dipartimento di Pianificazione, Design, Tecnologia dell’Architettura, della Sapienza Università di Roma, sta svolgendo quale interprete proattivo e propulsivo delle istanze sociali, culturali, economiche e politiche, che scaturiscono dalle profonde trasformazioni indotte negli ultimi decenni nei territori delle città italiane ed europee dai processi di metropolizzazione del territori
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
Dynamical stability in random Boolean Networks
No full textIn this work we propose a new approach to the stability analysis ofRandom Boolean Networks (RBNs). In particular, we focus on two families ofRBNs with k=2, in which only two subsets of canalizing Boolean function areallowed, and we show that the usual measure of RBNs stability - sometimesknown as the Derrida parameter (DP) - is similar in the two cases, while theirdynamics (e.g. number of attractors, length of cycles, number of frozen nodes) aredifferent. For this reason we have introduced a new measure, that we have calledattractor sensitivity (AS), computed in a way similar to DP, but perturbing only theattractors of the networks. It is proven that AS turns out to be different in the twocases analyzed. Finally, we investigate Boolean networks with k=3, tailored tosolve the Density Classification Problem, and we show that also in this case theAS describes the system dynamical stability
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
