Walking Through Florence to Discover the Stone-Built Cultural Heritage
No full textBathed in the charm of centuries of history and architectural beauty, the city of Florence is a kind of open-air museum which represents the historical memory of the city, from the Middle Age to modernity. The countless masterpieces are mainly made of the rocks outcropping close to the city and surrounding areas. Thus, Florence is characterized by the colours of its stone-built cultural heritage, the warm ochraceous and the cerulean grey of the Pietraforte and Pietra Serena sandstones, but also the white of marbles, the green of serpentinites, and the red of limestones. In addition, other natural lithotypes, together with artificial materials, were used to realise columns, decorations, claddings, masonry finishing, etc. To deepen the knowledge of the stone materials of Florence, the progressive web app “Florence RockinArt” may help us; it is addressed to all those who are interested in discovering the monuments of Florence by carefully observing the stone materials that make up them. The web app contains short historical and architectural notes on the main monuments but, first of all, detailed geological, mineralogical, and petrographic characteristics of the natural and artificial materials of which they are constituted. The best way to visit this charming city is on foot, getting the chance to walk into the history. In this paper, we suggest a selection among the most significant and suggestive walks through the city such as, for instance, looking for the differences between the sandstones Pietra Serena and Pietraforte, the search for churches decorated with the three colours, white, red, and green, or the hunt for little used polychrome materials
System Integration for Masonry Quality Assessment: A Complete Solution Applied to Sonic Velocity Test on Historic Buildings
No full textThe preservation of Built Cultural Heritage requires a careful diagnosis of the problems that characterize the historical masonries, through investigations aimed at assessing the quality of natural or artificial stone materials of which they are made. In particular, the diagnostics of masonry through Non-Destructive Techniques (NDT) is useful to deepen the knowledge of the construction characteristics, evaluate the state of conservation, and to monitor the effectiveness of the restoration interventions. Among the NDTs, the Sonic Velocity Test is largely used for evaluating the consistency of masonry and allowing the on-site identification of internal defects like fractures, voids, and detachments. The research involves the development of a complete management solution for the sonic measurements of different types of masonry and load-bearing elements. This solution consists of a website-based collaborative platform, a mobile/desktop application, and a reporting tool, which allows data processing from the on-site survey to their visualization and dissemination. The application of this system has been carried out by the LAM Laboratory of the Department of Earth Sciences (University of Florence) to evaluate the masonry quality in several historical civil and religious buildings and to improve the approach to diagnostics of Cultural Heritage
Integrated survey procedures: a methodological approach for documentation and representation applied to Emilia-Romagna theatres
No full textAfter the earthquake that struck the Emilia-Romagna Region in 2012, the need to activate efficient procedures for heritage conservation emerged. This paper presents a procedure for the integrated documentation of cultural heritage, starting from the current evaluation procedures, standards and tools for surveying seismic damage, namely the Form A (churches) and Form B (palaces) forms used by MiBAC (Ministry for Cultural Heritage). By adopting current tools, several information and details related to the historical, geo-morphological, stratified and structural data are lost. Starting from ongoing PhD research coordinated by the DIAPReM Centre of the University of Ferrara in collaboration with the Agenzia per la Ricostruzione dell'Emilia-Romagna-Sisma 2012, this contribution aims to deepen integrated survey procedures and management of digital tools. This contribution presents the overall methodological approach and a possible application on the Teatro Borgatti in Cento, Ferrara. Therefore, analysing the current scenario and State of the Art, a preliminary assessment of multilevel interpretation of damaged heritage will be illustrated as well as a possible management of seismic risk developing an interoperable and integrated BIM platform
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
