Il sistema naturale e agricolo
No full textIl volume, frutto di una ricerca collettiva tuttora in corso, pone due interrogativi: come riqualificare L’Aquila? Come rigenerare il suo tessuto socio-economico?
La frequenza dei fenomeni sismici nel nostro Paese ha ormai reso il problema della ricostruzione di una città non più una circostanza relegabile a una dimensione emergenziale, bensì un aspetto costante della ricerca architettonica e urbanistica italiana.
Il gruppo di studiosi guidato da Maria Cristina Forlani, dopo aver svolto un’attenta analisi del contesto naturale e costruito del capoluogo abruzzese, ha individuato nell’edilizia sociale l’ambito di studio e d’azione più promettente. Solo concentrandosi sulla rivalutazione di questo settore con un approccio eco-industriale (componenti edilizi da risorse locali riciclate e rinnovabili) sarà possibile sollecitare nuovamente l’economia cittadina. Tutto ciò presuppone la conoscenza approfondita del patrimonio collettivo, dalla quale soltanto può derivare un’analisi razionale delle sue funzionalità, e quindi un progetto credibile delle sue prestazioni future
L'ambiente costruito
No full textIl capitolo attiene alla fase di conoscenza sviluppata per acquisire le informazioni sulle caratteristiche degli abitanti nei complessi A.T.E.R. di Monticchio e Pretuto (Aq), dei sistemi costruttivi, dei fenomeni di degrado, dell'evoluzioone della domanda sociale e delle esigenze di intervento poste dalla normativa in vigore
OPTIMIZATION OF DURABILITY IN THE REUSE OF A STEEL ELEMENT OTTIMIZZAZIONE DELLA DURABILITA' NEL RIUSO DI UN ELEMENTO DI ACCIAIO
No full textIn the growing demand for environmental sustainability of buildings interventions, motivated by the depletion of non-renewable resources and by the occupation of the land, the reuse of materials resulting from demolition selective is a priority, presenting a particular relevance in the case of materials, such as steel, which require environmental and economic significative resources not only far the production ex-novo, but also far the recycling. It is proposed the definition of a methodological and operative procedure of reuse of a steel component, based on the current European legislation, depending on the degradation level and the residual performance, on the nominal life of the building in which there is the reuse and on the environmental conditions, in order to optimize the durability. We describe the comparison mode to evaluate the residual performance, the possible treatments that are possible to be made on site or in factory, emphasizing the important relationship between the preparedness treatments and the prevention treatments, the evaluation of the effectiveness of treatments and the construction methods for preventing the corrosion
PAESAGGI PERIFERICI Strategie di Rigenerazione Urbana
No full textIl volume è frutto di un’ampia ricerca, finanziata dal MIUR nell’ambito del programma PRIN 2008, condotta da cinque dipartimenti universitari italiani che hanno studiato strategie d'intervento finalizzate a rigenerare e valorizzare gli insediamenti di edilizia sociale realizzati nelle periferie urbane nella seconda metà del XX secolo.
La ricerca presuppone che oggi non è più sostenibile da un punto di vista sociale, economico e ambientale, sostenere uno sviluppo indiscriminato del territorio.
Lavorare sull’esistente diventa allora una priorità per salvaguardare il nostro futuro. Ripartire dalla rigenerazione dei paesaggi periferici è dunque la base della ricerca, che si è sviluppata e definita con i contributi degli autori, attraverso cinque macro-temi: identità urbana e sociale, connessione e accessibilità, rigenerazione, mutazione e qualità tecnico-ambientali.
Ognuno di questi contributi permette un’analisi puntuale delle problematiche e delle strategie di rigenerazione, che si condensano in casi studio emblematici per la realtà italiana come il quartiere Pilastro di Bologna o le Piagge a Firenze
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
