TLS e UAS 3D data integration for the knowledge and representation of a mid-18th century architecture: the Teatro Massimo Bellini in Adrano (CT)
Full text linkThis study, conducted on the Teatro Massimo Bellini in Adrano (CT), is part of a wider research aimed at the knowledge, valorization, and fruition of the theatrical and cinematographic heritage of Catania and its municipalities, through digital surveying techniques. This architectural heritage represents a powerful bond to the past for the city and its inhabitants. However, its typological connotations are often neglected or changed. Therefore, understanding these architectures is an essential step in their protection.The Teatro Massimo Bellini is located within a historicized urban space near the historic municipal garden, behind the ancient axis of Garibaldi Street, where the Mother Church and the Norman castle stand.Previous investigations conducted on the theater are purely historical-literary. No archival documents have currently been found to testify about its original stylistic formal and geometric characteristics, especially of the spaces that have been rearranged over time.Due to its typological and geometrical characteristics, we decided to proceed through an integrated survey, which could provide the necessary data for the graphic reconstruction of the building, ranging from an urban scale to a detailed scale.The presented study aims to experiment and integrate LIDAR (TLS) and SfM techniques (UAS) to obtain a three-dimensional data model useful to document the entire spatiality of the opera and its urban context. Indeed, the integration between terrestrial laser scanning (TLS) and Unmanned Aerial Vehicle (UAV) digital photogrammetry techniques is tested and verified.DOI: https://doi.org/10.20365/disegnarecon.29.2022.6</p
La sala e la scena del Teatro Massimo Bellini di Catania: “punti di vista” tra percezione e razionalità
No full textIl presente studio indaga il concetto dì “punto di vista” nella progettazione delle architetture teatrali di fine Ottocento valutando come sia mutevole, nello stesso spazio architettonico, il significato di percezione visiva della scena teatrale e dello spazio della sala, quindi del coinvolgimento degli spettatori alla narrazione scenica e contestualmente alla partecipazione sociale.
Vengono analizzate le scelte progettuali attuate all’epoca per la realizzazione degli spazi destinati alla platea e alla scena del teatro massimo Bellini di Catania, attraverso il raffronto tra i documenti di archivio del progetto, i dati ottenuti da rilievo digitale laser scanning e l’analisi dei tracciati geometrici regolatori e della visibilità dello spettatore, operata per confronto con la tipologia del teatro all’italiana.
La ricerca si serve del modello digitale tridimensionale utile a documentare l’impianto “a ferro di cavallo” dello spazio reale della platea e la sua separazione da quello illusorio della finzione scenica attraverso il boccascena, che riprendeva la struttura del scaenae frons rinascimentale, incorniciata dall’arcoscenico, funzionale a inquadrare lo spazio della visione.
Il rilievo e le analisi condotte a posteriori chiariscono le scelte progettuali attuate dai progettisti in un periodo in cui la figura dello spettatore era dominante ed in cui il teatro riveste una doppia funzione spettacolare, che riguardava sia lo spazio della scena sia lo spazio occupato dagli spettatori
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
