Il contributo delle tecnologie digitali per la valorizzazione del patrimonio rupestre pugliese
No full textThe essay concerns the recent work carried out as part of a multidisciplinary research on some rocky churches in the southern Apulia, conducted in collaboration with the Chair of History of Medieval Art of the University of Salento and of the University of Bari. The work aims at the knowledge and the monitoring of the fresco paintings inside three rocky environments, two of which are located in Lama d’Antico, in Fasano (BR), and the other two in Vaste di Poggiardo and Giurdignano (LE). The contribution illustrates methods and data acquired during the fieldwork, carried out through a multidisciplinary approach. From the image-based Techniques for the survey in Camera-Scanner to the restitution of 3D models of the surfaces; from the virtual survey of paintings to the realization of a stereoscopic platform of fruition QVTR-based aimed at the visualization and the enhancement of the Apulian rocky heritage. All data were obtained through low cost technologies and processed in relatively short times, about two months, divided between fieldwork and processing in laboratory
Eligio, Martino e Giacomo. Santi d’Occidente nelle chiese rupestri pugliesi
No full textThe paper examines the life, the devotion, the iconography and the presence of three western saints – St. Martin, St. Eligius and St James the More – in the rupestrian churches of Apulia between Middle Ages and Modern Age. The iconographical study shows all its potential to understand devotional and spiritual dynamics in the rocky habitat
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
