Architetture per il restauro: l'anastilosi
No full textIl volume propone una riflessione sull’anastilosi nella sua più ampia accezione e come tema specifico di restauro. L’argomento è affrontato dal punto di vista concettuale e terminologico, partendo dalle definizioni di anastilosi ‘diretta’ e ‘indiretta’, fino alle declinazioni della ‘ricostruzione’ e alle nuove possibilità offerte dall’‘anastilosi virtuale’. Non si tralasciano inoltre considerazioni sul significato di ‘frammento’ e di ‘rudere’ nell’ambito della tutela del patrimonio storico e artistico.
I saggi si articolano fra storia, teoria e prassi, rimandi all’attualità e a prospettive future, aspetti tecnico-diagnostici ed efficaci esemplificazioni, nel comune interesse per il trattamento dei resti di un antico edificio per garantirne la conservazione, la ‘reintegrazione dell’immagine’, un ruolo nel contesto in cui sono stati prodotti o una ricollocazione museale.
Ne deriva un significativo quadro d’insieme sull’anastilosi come pratica di restauro, soprattutto in campo archeologico, anche depositaria di valori museografici diversamente declinabili
La basilica-memoriale di Mosè sul monte Nebo, in Giordania, tra anastilosi e ricostruzione
No full textIl saggio ripercorre le vicende costruttive del memoriale di Mosè sul monte Nebo in Giordania, dalle campagne di scavo degli anni Trenta del Novecento allo stato attuale. Sulla base delle fonti bibliografiche e delle acquisizioni delle esplorazioni archeologiche del 2012-2014, sono analizzate le operazioni di anastilosi ‘indiretta’ delle colonne e di ricostruzione del perimetro murario della basilica. Questi lavori definiscono, a partire dai primi decenni del XX secolo, l’ambito progettuale entro il quale si collocano i diversi interventi di ricomposizione dell’impianto a tre navate, finalizzate a garantire la leggibilità del monumento (con suoi valori testimoniali e simbolici) e il suo utilizzo per le funzioni religiose. Nel 2016, il restauro di Roberto Sabelli si fonda sul riconoscimento dell’edificio nel suo raggiunto ‘equilibrio formale’. Il progetto adotta delle soluzioni figurative di qualità per adeguare il santuario ai contemporanei usi liturgici e museali, nel rispetto delle sue trasformazioni e dell’anastilosi indiretta delle colonne, storicizzata nel processo di modifica.The essay traces the constructive events of the Moses memorial on Mount Nebo, Jordan, since the excavation campaigns of the 1930s to the present state. The “indirect” anastylosis of the columns and the reconstruction of the wall are here analyzed on the basis of bibliographical sources and the acquisitions of the archaeological explorations of 2012-2014. Starting from the first decades of the twentieth century, these works define the design context within which the various interventions for the recomposition of the three-nave system are located, aimed at guaranteeing the legibility of the monument (with its testimonial and symbolic values) and the its use for religious services. Roberto Sabelli’s restoration in 2016 was based on the recognition of the building’s achieved “formal balance”. The project adopts quality figurative solutions to adapt the sanctuary to contemporary liturgical and museum uses, respecting its transformations and the indirect anastylosis of the columns, historicized in the modification process
L'anastilosi fra errori, mistificazioni e correzioni
No full textAnastylosis is a restoration technique, concerns about the reconstruction, not necessarly complete, of structures or buildings built without mortar, of which contiguous elements have been found. The characteristics of these elements must allow a ’certain’ relocation, based on material evidence. The distinctive element of the anastylotic operation concerns precisely in reassembling of the pieces guided by the objective testimony provided by the fragments themselves, which are scrupulously detected and studied in their geometric and material qualities. As it’s well known, this procedure has some interpretation problems and is less 'objective' than it appears. Some examples of anastylosis with incorrect execution are analyzed in an attempt to identify the origin of the errors, more or less aware of
Le reintegrazioni virtuali
No full textLe reintegrazioni virtuali rappresentano un veicolo di comunicazione visiva per trasmettere informazioni e comunicare il nostro patrimonio culturale. Esse consentono all’osservatore una lettura ‘guidata’ grazie al processo di sintesi, di gerarchia e di astrazione effettuato per colmare situazioni lacunose, sottolineare tracce ancora presenti o ricostituire contesti non più visibili secondo espressioni critiche, pedagogiche, sociali o creative
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
