Le “Avvertenze d’Arte“: prima carta italiana del restauro delle superfici architettoniche, dettata da Alfonso Rubbiani
No full textLe "Avvertenze d'arte" rappresentano la prima Carta italiana del restauro delle superfici architettoniche, che costituisce un'estensione della più nota Carta del restauro di Camillo Boito del 1883, presentata in occasione del Congresso nazionale Ingegneri e Architetti di Roma. Lo scopo innovativo e di perdurante attualità delle “Avvertenze d’arte”, nate sotto l’egida del Comitato per Bologna storico e artistica, risiede nell’intento di far comprendere che pur la semplice manutenzione delle superfici architettoniche non è un fatto meramente tecnico ma che esso consiste in un vero e proprio progetto di restauro architettonico, un atto critico da condurre mediante la comprensione circostanziata del significato linguistico, storico e tecnico dei differenti tipi di finiture. L’innovazione va ben oltre il concetto di ‘progetto del colore’ e di ‘ripristino’ delle superfici architettoniche laddove affronta, poi, due temi cruciali del restauro che sono quelli della conservazione delle “patine” e della “distinguibilità” degli interventi negli edifici del Quattrocento per salvaguardarne, mediante la necessaria accortezza tecnica, gli importanti valori storici e culturali.
Il senso dell’impianto concettuale che presiede alle “Avvertenze” è, indirettamente, quello della tutela diffusa del paesaggio urbano afferente all’intero centro storico che tanto stava a cuore al Rubbiani e al Comitato, impegnati, nello stesso periodo di emanazione delle “Avvertenze”, nella lotta per la salvaguardia della cinta urbica di Bologna, con tutte le sue mura e le sue porte
The restoration and repair of Bolognese timber ceilings: material culture and decoration
No full textPresentation of the research method about wooden historical
ceilings during the period included between the XVth and the
XVIIIth centuries. The method is based by the intersection of
indirect sources with the analysis of 50 real cases of ceilings,
chosen from the most significant inside some prestigious
historical buildings in the city of Bologna. Moreover, this method
has purposes to understand the several typologies, the historical
evolution, the constructive vocabulary, the relationship between
the techniques used and the decorative system for wooden
historical ceilings.
Analysis of indirect sources, with a particular focus on the
Bolognese ancient price lists (Spinelli and Angelotti) and on their
important contribute in order to define a typical constructive
vocabulary.
Panoramic classification of ceilings types present in Bologna
deriving from the analysis of 50 real cases, accurately surveyed
and studied into their main constituent parts, and from the
comparison with historical indirect sources. Introduction of
wooden ceiling finishings and decorations, studied in their
temporal evolution and in their artistic and technological functions.
A case of study, the reinforcement and restoration of ‘Serlio’s
Style’ ceiling in Palazzo Fava
Abitare gli spazi della conoscenza. La fabbrica classense
Full text linkLiving spaces of the ancient knowledge, means creating a physical bridge between past and future, that reveal itself in the regeneration of the historical architecture as a place of living documentary evidence, usable according to the needs of the contemporary community. As a result of the latest restoration works, supported by the local administration, Classense Library of Ravenna is the perfect example of these concepts. Works with a strong sustainable value for a social and environmental role, because they allow to recognizing this building, the monumental and cultural reference point of the city, which reflects the community identity and rediscovers, living spaces, a high level of perceptive and psychophysical comfort.
The Classense library was constituted in 1515 by the arrival in Ravenna of the Camaldolesi monks at the monastery and church of St. Nicholas and the Mercy of St. Bartholomew hospital, which were restored, extended and modified until 1798. Within the complex, that occupies a block of about 10.000 sqm, the works touch the area of the 16th century minor court that through time has undergone considerable changes hosting multiple functions, from the hospital to the convent and then school of Fine Arts.
Interventions of restoration and refurbishing, started in the public library in 2001, will be related to the detailed documentary studies that will allow to choose how to preserve and enhance the testimonies of the historical evolution of the building, even through the conservation of matter and traces and the removal of incongruous additions.
The building will be made safe, both under a static profile and for accessibility, according to the current regulations, and for the suitable arrangement of the plant system to the new features. Simultaneously to a study of functional reuse of the spaces and therefore the new entry flows and horizontal and vertical path in the rooms.
The restoration faces the contemporary choices using steel, wood, glass and brick for the new additions. The interior forniture in metal and wood were designed ad hoc, for storing books and to allow the passage of the technological components and lighting, necessary for the use of the spaces, in order to preserve the historical existing. The project of new geodetic false ceiling enhances the precious frescoes discovered by stratigraphictest
Tasselli sospesi a Bologna. Contributo alla costruzione di un atlante dell’architettura locale
No full textThe research about bolognese suspended ceilings was enveloped comparing the copious local production on the manuals with
the numerous data collected through survey campaigns and archivist investigations. From the research emerges that in Bologna,
as highlighted by Serlio in his treaty, exists a constructive and figurative glossary deserving to be collected and analyze, since
representative of a local reality, that stands out in the Italian panorama of that period.
The various typologies observed were analyzed and supported by graphic tables, synthetic and detailed, that highlight also the
relation between figurative language and constructive choices, in purpose to create a functional sensibility to their conservation
and seismic improvement project
Le Mura di Lucca: restauro e valorizzazione come premessa per lo sviluppo culturale del territorio
No full textLa conoscenza e la tutela delle cinte murarie urbane si intreccia con la memoria umana costituente l’identità locale della comunità da esse racchiusa. Un progetto che tenda alla valorizzazione di questi monumenti a scala urbana deve, quindi, permettere uno sviluppo economico e culturale del territorio che ha nel monumento il suo simbolo.
Il caso di studio delle mura di Lucca, unica cinta muraria totalmente conservata del Rinascimento italiano, può essere usato come esempio per la tutela e valorizzazione di molte altre cerchie urbane che necessiterebbero di interventi per la conservazione. Inoltre, tenendo conto della direzione per l’auto-sostentamento economico dei monumenti in cui anche il FAI (Fondo Ambiente Italiano), si vogliono promuovere nuove modalità di valorizzazione che non costituiscano mero sfruttamento del bene ma coinvolgano in una partecipazione diretta ai valori del paesaggio e del patrimonio culturale.
Il monumento simbolo della città deve poter avere un ruolo anche oggi per la città stessa: da un lato essa deve diventare un sistema in cui tutti i sui elementi costituenti lavorino in modo sinergico a raccontare l’identità culturale della città stessa; dall’altro si potrebbe andare verso a una visione del patrimonio culturale allargata a quella di “produzione di cultura”, che ritrovi la coscienza dei luoghi, dando uguale importanza alla tutela e alla promozione culturale.
La promozione di una fruizione attiva e proattiva, quindi non passiva, necessita di un coinvolgimento sempre maggiore dei residenti in un progetto di evoluzione dell’identità locale che potrebbe evidenziare l’esigenza di un dialogo fra le antiche architetture e nuove strutture. La sfida è quella di avere una tale comprensione del monumento da far sì che il nuovo siano legittimate dal passato contemporaneamente risponda alle esigenze di fruizione
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
