Lo spazio monumentale nella città tardoaantica. Architettura e immagine di piazze e vie colonnate nei grandi centri del Mediterraneo Orientale
Full text linkI portici pubblici delle città tardoantiche oltre a svolgere un importante ruolo urbanistico e sociale, veicolavano all’osservatore una molteplicità di messaggi inscindibilmente legati all’immagine delle loro fronti monumentali e alla funzione degli edifici a cui introducevano: potenza economica della città e delle sue élites, propaganda di matrice imperiale o religiosa, modelli urbani di riferimento.
Lo scopo di questa ricerca è stato quello di analizzare l’architettura delle piazze e delle vie porticate dei principali centri del Mediterraneo orientale, con particolare riferimento alle città della Grecia e della costa occidentale dell’Asia Minore, nell’intento di delineare i caratteri propri della monumentalizzazione di questi spazi tra IV e VI secolo d.C. Attraverso l’esame di alcuni tra i complessi scelti come casi studio (Macellum-forum di Durazzo; Via Arcadiana di Efeso; Hemicycle Building di Corinto; Foro di Teodosio a Costantinopoli), la ricerca ha posto particolare attenzione all’analisi e alla restituzione grafica dell’immagine delle piazze circolari e di quelle curvilinee dette a ‘sigma’, due tipologie architettoniche che insieme alle più comuni agorai a pianta rettangolare e alle vie colonnate costituirono i principali elementi del panorama urbano della nuova capitale Costantinopoli ed ebbero ampia diffusione nelle città tardoantiche delle province orientali dell’impero. Gli obbiettivi della ricerca sono stati i seguenti: (a) tracciare un quadro il più completo possibile delle caratteristiche architettoniche delle piazze porticate e delle vie colonnate presenti nelle città di Grecia ed Asia Minore, utilizzando come termini di confronto anche altri edifici presenti nelle città del Mediterraneo orientale; (b) evidenziare la valenza urbana e ideologica dello spazio porticato in età tardoromana sulla base della percezione visiva che se ne poteva avere in antico; (c) restituire graficamente gli elevati delle strutture e le prospettive possibili da determinati punti visuali scelti nei principali casi di studio al fine di comprendere come poteva essere percepita l’architettura degli spazi colonnati dagli antichi fruitori di strade e piazze.
Si tratta di un tema che per la sua vastità non è stato ancora trattato con una visione complessiva volta a considerare nel loro insieme i sistemi colonnati di strade e piazze soprattutto riguardo alle fasi tardoantiche, spesso ritenute meno interessanti delle più monumentali realizzazioni dell’età imperiale. Se da un lato, quindi, l’ampiezza del tema ha costituito uno dei limiti oggettivi della ricerca, in parte superato attraverso la scelta di specifici casi studio, dall’altro ha rappresentato un’occasione per riconsiderare e aggiornare lo stato delle ricerche rispetto a una serie di pubblicazioni sul tema edite ormai da oltre un ventennio.The public arcades of the late antique cities, besides playing an important urban and social role, conveyed to the observer a multitude of messages inseparably linked to the image of their monumental fronts and to the function of the buildings to which they gave access. These messages referred to economic power of the city and of its elites, imperial or religious propaganda or architectural models of reference.
The purpose of this research was to analyze the architecture of the squares and the porticoed streets of the main centers of the Eastern Mediterranean, with particular reference to the cities of Greece and the Western coast of Asia Minor, with the aim of outlining the characteristics of the monumentalization of these spaces between the 4th and the 6th century A.D.
Examining some of the complexes chosen as case studies (Macellum-forum of Durres, Via Arcadiana of Ephesus, Hemicycle Building of Corinth, Forum of Theodosius in Constantinople), the research has paid particular attention to the analysis and the architectural restitution of the image of the circular squares and the curvilinear ones called 'sigma plazas', two architectural types that together with the more common rectangular agoras and the colonnaded streets constituted the main elements of the urban landscape of the new capital Constantinople and had wide diffusion in the late-antique cities of the Eastern provinces of the empire. The objectives of the research were the following: (a) draw a complete picture of the architectural characteristics of the porticoed squares and of the colonnaded streets in the cities of Greece and Asia Minor, also referring to other buildings in the cities of the Eastern Mediterranean; (b) highlight the urban and ideological value of porticoes in the late Roman age on the basis of the visual perception that a person could have had in ancient times; (c) graphically reconstruct the buildings and the perspectives possible from certain visual points chosen in the main case studies in order to understand how the architecture of the colonnaded spaces could be perceived by the ancient users of streets and squares.
This is a topic that, due to its vastness, has not yet been treated with an overall vision aimed at considering collectively the colonnades of streets and squares, especially regarding the late-antique phases, often considered less interesting than the more monumental achievements of the imperial age. If on the one hand the amplitude of the topic has constituted one of the objective limits of the research, partly overcome through the choice of specific case studies, on the other hand it represented an opportunity to reconsider and update a research on this topic published over twenty years ago
Integrated methods for reconstructing the decoration and production process of the frigidarium wall-paintings, at the Sarno Baths, Pompeii
Full text linkThis paper explores the potentiality of investigating Roman wall decorations by integrating the visual examination of the technical aspects of wall paintings and plasterworks, to the virtual reconstruction. It also aims at reconstructing the process of making wall decorations and at identifying the decorators, as an occasional group of workers or a properly organized workshop. The frigidarium (i.e. the room with a cold-water pool) in the Sarno Baths was selected as case study, to apply this approach. The presence of several missing parts allowed the observation of the full stratigraphic sequence of paintings and plasterworks. The visual analysis and the identification of the tool-marks provided the necessary elements, to reconstruct the sequence of operations performed by the artisans, during the process of making. Features suitable to identify the contribute of different artisans to the decoration project were also identified. The accurate survey of the preserved portions of decoratio..

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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
