La fortuna del capitello ionico nella Gortina imperiale: i modelli microasiatici e le rielaborazioni in marmo grigio locale
Get PDFLe indagini archeologiche nella città di Gortina hanno riportato in luce alcuni capitelli ionici di modello microasiatico in marmo importato, databili alla seconda metà del II sec. d.C., ma anche un gran numero di capitelli ionici in marmo grigio locale, con ogni evidenza prodotti in loco tra la fine del II e gli inizi del III sec. d.C. Si tratta di membrature riutilizzate in edifici più tardi e spesso reimpiegate come materiale da costruzione o rifunzionalizzate in vari modi. La loro relativa abbondanza, per alcuni versi insolita, testimonia non solo la peculiare fortuna del tipo nella capitale cretese, ma anche la grande attività degli atelier di scalpellini locali, almeno a partire dalla seconda metà del II secolo. Il contributo cercherà, attraverso l’analisi di alcuni esemplari, di delineare le caratteristiche di questi capitelli di Gortina e le ragioni della loro fortuna, all’interno della dialettica tra modelli decorativi di importazione e tradizione locale.Excavations in the site of Gortyna brought to light some Ionic capitals related to Asia Minor models, dating from the second half of the 2nd century AD; they are realized either in imported marble or in the local one, carved in loco between the late 2nd and the early 3rd centuries. These capitals were reused in later buildings and often reemployed as building materials or re-functionalized in many ways. Their somehow unusual abundancy proves not only the success of the type in the Roman Crete capital, but also the flourishing activity of local craftsman ateliers from the second half of the 2nd century AD. The current article aims to describe the features of this local Ionic capital typology and the reason for their success, in the wider dialectic relationship between imported decorative models and local tradition
Elementi di un modellino architettonico in pietra dal Santuario di Contrada Mango a Segesta
Get PDFNel 1957, in occasione di una campagna di scavo in Contrada Mango di Segesta, Vincenzo Tusa rinvenne due frammenti litici di membrature architettoniche miniaturistiche, appartenenti ad un fregio dorico e ad una cornice, parimenti dorica. In questa sede, oltre a proporre un’analisi dettagliata dei due frammenti, si cercherà di avanzare alcune ipotesi sul contesto della loro realizzazione, sulla loro funzione e sull’eventuale monumento di riferimento, con una rapida disamina della problematica legata ai paradeigmata architettonici nell’antichità.In 1957, during an excavation campaign in Contrada Mango of Segesta, Vincenzo Tusa found two lithic fragments of miniaturistic architectural elements, belonging to a Doric frieze and a Doric horizontal geison. In this contribution, as well as offering a detailed analysis of the two fragments, we will try to put forward some hypotheses on the context of their production, on their function and on their reference monument, with a rapid examination of the problems linked to the architectural paradeigmata in the antiquity
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

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
