Urban regeneration of villages as an opportunity. Tools and methods in the case study of Mogoro in Sardinia.
No full textIl contributo illustra lo studio condotto sui tessuti alterati in prossimità del centro storico del comune
rurale sardo di Mogoro, con l’obiettivo di valorizzare l'identità architettonica e urbana del villaggio e
riqualificare i tessuti edilizi sul piano della qualità abitativa. La visione processuale che connota le
trasformazioni e gli adattamenti delle strutture insediative e degli spazi dell’abitare e l’interpretazione
della crisi della vita in città possono consentire di rivalutare le condizioni abitative strutturali dei centri
minori (ecologia dello spazio domestico, bassa densità, ampi spazi aperti pubblici e privati,
distanziamento sociale, coesione e sostegno sociale etc), come opportunità per un rinnovato rapporto
tra uomo e paesaggio. Il Piano per il centro matrice di Mogoro recepisce lo stato di necessità
dell’insediamento regionale e propone un sistema di regole aperto e flessibile che accoglie i processi
modificativi coerenti e compatibili con la tradizione. Questo principio d’inclusività è alla base della
strategia che mira a condizioni d’abitabilità di sempre maggiore qualità dei centri minori,
mantenendone vivo il dinamismo, aspetto oggi rilevante se riletto alla luce della profonda crisi che le
città attraversano, aggravata dagli effetti della pandemia.
Sul piano metodologico l’oggetto della conservazione non coincide in modo esclusivo con il costruito
in quanto tale, ma in quanto espressione dei principi insediativi. La modificazione si attua dentro una
strategia operativa interna ai processi in atto, con l’obiettivo non di cristallizzarli, ma d’indirizzarli e
ricondurli a una logica di sistema, anche utilizzando la capacità edificatoria residuale potenzialmente
decisiva, come leva per produrre risultati concreti. Sul piano operativo l’approccio generale è
sistemico e interscalare, seppure attraverso una declinazione attuativa agopunturale nelle azioni.
L’analisi tipo-morfologia dei tessuti, l’individuazione di aree ed edifici da conservare, e la definizione
di un sistema di "regole" e di tipologie d’intervento ammissibili per il recupero si traduce in un sistema
di abachi analitici, delle trasformazioni e delle mitigazioni come strumenti di progetto. La definizione
del quadro strategico per la rigenerazione dei tessuti si completa con una sequenza coordinata di
progetti pilota con l’obiettivo della riattivazione sostenibile di alcuni vuoti urbani, unitamente alla
valorizzazione della rete storica dei pozzi come carattere identitario dello spazio pubblico
Projects for a “disconnected” heritage. A new identity for archaeological landscapes system of Marmilla
No full textThis paper is part of a broader research framework that aims to develop strategies for knowledge and intervention on the huge prehistoric and protohistoric archaeological heritage of Sardinia, focusing on the historical region of Marmilla. The method is based on the analysis of the relationships between the site and the rural landscape and the systematization of archaeologies with existing multi-layered settlement networks. Specifically, this paper triggers a process that aims to bring attention back to the places of the archaic, proposing services and routes that can promote their visibility and, consequently, make them known and appreciated, activating a virtuous mechanism of valorization. The objectives of the work are reconstructing the identity of the places and preserving this unique heritage. Through the reinterpretation of existing features, a current and contemporary response is proposed to interpret the sites' needs in relation to accessibility in the broadest sense of the term. Some sites already appear to be partially equipped with accommodation and reception facilities, but these are often oversized or poorly functioning. Architectural and landscape design then becomes a necessary tool for fruition and enhancement, through actions that are focused on the maintenance and updating of existing buildings of proximity, the insertion of new minimal devices, paths, and coverings in archaeological areas, but also on the issue of the management of excavated material and processes related to the needs of the archaeological site. At the same time, however, the project is also a tool for general consideration, verification and fine-tuning of possible approaches and paradigms. The principles of intervention invoke the concepts of enclosure, by redefining access thresholds and limits, land and soil manipulation, and excavation, as a means through which to bring out the materiality and massiveness of the built environment and to provoke deep relationships between the present landscape and archaeology. The case studies are part of a network of archaeological sites from the Nuragic period (1700-800 B.C.) that are strongly interconnected and are located in Marmilla, a historical region of central Sardinia. We find Sa Scaba 'e Cresia in Morgongiori, Nuraghe Cuccurada in Mogoro, Sa Domu 'e S'Orcu in the jara of Siddi, Nuragic Villagio Brunk 'e s'Omu in Villaverde, Nuraghe Su Mulinu in Villanovafranca, Nuraghe Santu Miali in Pompu and the Sacred Well of Sant'Anastasia in Sardar
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
Re-qualification and anti-seismic structural adjustment of modern architecture buildings in the historic centresThe case of the former University Paediatric Clinics in Cagliari
No full textRiqualificare l’architettura moderna, spesso inserita in ambiti storici consolidati di assoluto valore, è ormai diventata una priorità di intervento delle nostre città. Contestualmente al ripensamento in senso spaziale, architettonico, tecnologico-prestazionale, si pone l’esigenza/urgenza dell’adeguamento strutturale antisismico. Edifici d’avanguardia per il momento storico in cui sono stati concepiti scontano proprio la loro stessa genesi sperimentale che, anche nei casi d’eccellenza, rende necessari l’adeguamento normativo, prestazionale e più in generale d’uso contemporaneo. Il contributo illustra, attraverso il caso studio del progetto di riqualificazione (condotto con la consulenza scientifica del DICAAR) delle ex-cliniche pediatriche dell’Università di Cagliari, una metodologia di intervento integrata per il ripensamento dello spazio, associato a un’ipotesi di variazione di programma d’uso strutturalmente più gravoso con conseguente adeguamento antisismico. Un approfondito progetto di conoscenza condotto con tecniche non distruttive e con prove di carico ha permesso di ricostruire la caratterizzazione ma-terico-strutturale dell’edificio e la sua dimensione tecnico-costruttiva che, in man-canza di documenti di archivio, è stata un’imprescindibile base conoscitiva per l’intervento a tutte le scale.The re-qualification of modern architecture buildings, often embedded into consolidated historical areas of absolute value, has become a priority in our cities. Together with the spatial, architectural, technological and performance redevelopment, there is a need/urgency for seismic structural adjustment. These buildings, that were pioneering in their conception, suffer from their own experi-mental genesis which requires regulatory and performance adjustment even in cases of excellence. More in general, actions to adapt these building to contemporary uses are more than urgently needed. Through the case study of the redevelopment project (carried out with the expert advice of DICAAR) of the former University paediatric clinics of Cagliari, the paper illustrates a methodology of integrated intervention which aims to rethinking spaces, together with a hypothesis of use-programme which involves heavier structural modifications, with consequent anti-seismic adjustment. In the absence of archive documents, a thorough knowledge process was conducted involving non-destructive techniques and load tests. This allowed the reconstruction of the material-structural characterisation of the building and its technical and constructive dimension, that were pivotal for the full-scale intervention
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
