Venerare la Vera Croce: osservazioni sulla stauroteca bizantina di Grado
No full textLa stauroteca d’argento dorato del Tesoro di S. Eufemia a Grado è stata generalmente considerata nella storia degli studi come un prodotto delle officine bizantine dell’inizio del VII secolo. La tradizione ha collegato il suo arrivo nella città adriatica alla donazione fatta dall’imperatore Eraclio (610-641) al patriarca gradese Primigenio. Mentre la provenienza dall’Oriente bizantino è indiscutibile, l’attribuzione cronologica deve essere ripensata sulla base di considerazioni stilistiche (per quanto possibile, dato il precario stato di conservazione dell’oggetto), tipologiche, paleografiche e documentarie. Viene qui condotta una
nuova disamina delle fonti archivistiche di età medievale e moderna, delle testimonianze grafiche e dei modelli di riferimento per ricostruire la possibile forma originaria del reliquiario e la sistemazione del suo prezioso contenuto. Su un piano più ampio, questo articolo mira a esaminare i rapporti culturali e artistici tra Bisanzio e l’Italia nel Medioevo, attraverso le vicende che legarono il patriarcato di Grado a Venezia e al Mediterraneo orientale.The gilded silver staurotheke from the Treasury of St. Euphemia in Grado has been generally considered in scholarship to be a product of the Byzantine workshops of the early 7th century. Tradition has associated its arrival in the city on the Adriatic with the donation made by Emperor Heraclius (610-641) to the Grado patriarch Primigenius. While its provenance from the Byzantine East is indisputable, its chronological attribution must be reconsidered based on stylistic (as far as possible, given the object’s poor state of preservation), typological, palaeographical and documentary considerations. A new investigation
of medieval and modern archival sources, graphic evidence, and models is hereby conducted in order to reconstruct the possible primitive form of the reliquary and the arrangement of its precious contents. More broadly, this article aims to explore the cultural and artistic relations between Byzantium and Italy in the Middle Ages, through the events that tied the Patriarchate of Grado to Venice and the Eastern Mediterranean
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
