Antonio De Bellis: Le (molto incerte) vicende biografiche e qualche considerazione
Get PDFThe Neapolitan 17th century was characterized by such great cultural and artistic ferment that it was labelled as the Golden Age. A myriad of architects, sculptors, painters and craftsmen created works of great value that changed the face of the Viceroyalty capital forever.
Among the most appreciated painters at the time, as shown by the many works that are now part of his catalogue, but for a long time fallen into oblivion, also for the almost total absence of documents, there is certainly Antonio De Bellis: an artist who has aroused the interest of scholars since the 1970s, also becoming part of the group of painters involved in the vexata quaestio on the identity of the Maestro degli Annunci ai pastori.
Often mistaken for Bernardo Cavallino, as proof of his works’ quality his artistic path has its roots in Caravaggesque naturalism as interpreted by Battistello, Filippo Vitale and Jusepe de Ribera. Following in this latter’s footsteps, like so many others, he participates in the coloristic revolution coming on the one hand, from Rome, with the rediscovery of the 16th century Venetian Masters by a group of French artists, first of all Poussin, and, on the other hand, from Van Dyck’s works, full of Mediterranean light.
Antonio De Bellis’ attempt to maintain the link with his formative painting style while adhering to these new instances, however, does not last long and so his final two canvases lack the mordant of his previous production.Il Seicento napoletano fu caratterizzato da un così grande fermento culturale e artistico da meritarsi l’appellativo di Secolo d’Oro. Una miriade di architetti, scultori, pittori e artigiani diedero vita a opere di grande pregio che cambiarono per sempre il volto della capitale del Viceregno.
Tra i pittori ai tempi più apprezzati, come dimostrano le tante opere che oramai fanno parte del suo catalogo, ma per tanto tempo caduti nell’oblio, anche per la quasi totale assenza di dati documentari, c’è sicuramente Antonio De Bellis: un artista che dagli anni ’70 del Novecento ha stuzzicato l’interesse degli studiosi entrando anche a far parte della rosa di pittori coinvolti nella vexata quaestio sull’identità del Maestro degli Annunci ai pastori.
Spesso confuso con il Cavallino, a riprova della qualità di molte sue opere, dal quale si discosta per un certo arcaismo persistente in tutta la sua opera, il suo percorso artistico affonda le radici nel Naturalismo di matrice caravaggesca, ‘napoletanizzato’ da Battistello, Filippo Vitale e dal deus ex machina della pittura di quel periodo nella città partenopea, Jusepe de Ribera. E seguendo le orme di quest’ultimo, come tanti altri partecipa a quella rivoluzione coloristica che arriva da un lato da Roma, tramite la riscoperta dei Maestri veneti del ‘500 da parte di un gruppo di pittori francesi, primo fra tutti Poussin, e dall’altro dalle tele piene di luce ‘mediterranea’ del Van Dyck.
Il tentativo di Antonio di mantenere il legame con i modi della sua formazione, pur aderendo a queste nuove istanze, non regge però a lungo e quelle che al momento sono ritenute le sue ultime due tele, non hanno quel mordente che aveva caratterizzato invece la sua produzione precedente
The rehabilitation of an aging masonry building with (new !) suspension floors
No full textThe rehabilitation of an early '900 Industrial Archaeology building in the centre of Rome has been constrained by conservation issues due to its standing onto a unique archaeological site where Archaeological Autorities excluded any foundation works; in the meanwhile the new urban plan allowed to increase the surfaces of the building dividing 7,5m height large halls with new floors. The project had thus to transform constraints into design characteristics: xlam collaborating with steel reticolar trusses for a new light roof and xlam-steel light floors hanging below trusses and connected to the surrounding masonries by kinematically amplified viscous dampers, optimized to reduce out-of-plane seismic displacements of walls while achieving the restraint of suspension floor movements. Aspects of Standards for this particular project are also discussed
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Synthesis of a mixed carboxylate-phosphinate AAZTA-like ligand and relaxometric characterization of its Gd(III) complex
No full textThe synthesis of the new polydentate ligand AAZ2A2PEt derived from the heptadentate polyaminocarboxylic ligand AAZTA (6-amino-6-methylperhydro-1,4-diazepine-N,N′,N″,N″-tetraacetic acid) in which two acetate groups were replaced by methyleneethylphosphinic pendant arms is reported. The relaxometric behavior of the corresponding mono-aquo GdIII complex was also investigated
Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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
