Il tesoro di Montella e i contrassegni dei massari nella monetazione aurea veneziana
Get PDFIl contributo sintetizza il tema dei contrassegni adottati dai massari, ovvero dai sovrintendenti alla zecca di Venezia, per marchiare i ducati d’oro coniati nella Repubblica Serenissima. Il fenomeno della marchiatura delle emissioni veneziane è stato già in passato oggetto di ricerche limitate però al sistema di segni adottato per le monete argentee. Minor attenzione è stata data invece alle marchiature impresse dai massari sulle emissioni auree, anche per via dell’esiguo numero di segni conosciuti attestato per queste emissioni. La recente pubblicazione da parte di Matteo Broggini del cosiddetto tesoro di Montella, un corpus di almeno 210 monete d’oro tra cui sessanta ducati veneziani databili tra il XIII e XIV sec., oggi conservato presso il Museo Archeologico Nazionale di Napoli, ha tuttavia permesso l’identificazione di nuovi tipi di segni, incrementando così il repertorio di marchi noti. Sulla base di un’analisi del nuovo materiale, effettuata alla luce dei dati provenienti da conii più tardi già noti in precedenza agli studiosi, gli autori ci offrono una sintesi della storia dello sviluppo del sistema di segni adottato dai massari veneziani a partire dall’introduzione del ducato nel 1284 fino alla fine del Trecento. Particolare attenzione viene data alla tendenza di tali segni a diventare sempre più complessi per permettere di distinguere tra loro i marchi dei singoli massari. In tale fenomeno è da ricercare la causa dell’abbandono verso il 1400 dell’impiego di un sistema di marchiature dei massari sui ducati aurei veneziani
La città, il signore, l’imperatore : segni di identità su monete medievali e moderne: alcuni esempi
No full textItalian city coinages were usually identified by local symbols such as the fleurdelis for Florence or the city-gate for Genoa, while some other coinages continued traditional imperial epigraphic types (Milan). The images of local saints became more prominent on the silver “grossi” (13th century onwards). Between the late 13th and the early 14th centuries, new lords progressively gained power over vast Italian territories, usually through the imperial vicariate; some of their coins display a small eagle, others a heraldic device such as the “biscia” (snake) in Milan or the “scala” (ladder) in Verona.
This paper intends to focus on how the new lords adapted or replaced local signs of identity and developed their own coin iconography. After an introduction by Lucia Travaini, Maila Chiaravalle deals with the Milanese coinage, illustrating the use of the images of St. Ambrose and the “biscia” over a long period. The “biscia”, a symbol of the Visconti family, first appeared as a secondary element in the legends of the earlier Visconti coinages, whose rule started in 1329; later, with Galeazzo II and Bernabò (1354-1378), the iconographic message became more complex as the Visconti power expanded even outside of Lombardy: the “biscia” became therefore more prominent in the field of largely used coins such as the “grosso”, “pegione” and “sesino”. Finally, Federico Pigozzo examines in detail two cases showing how different the fortune of a “stemma” could be: 1) in Verona, the personal “stemma” of Cangrande della Scala (1308-1329) disappeared rapidly from local coinage; 2) in Trento, the “stemma” adopted at the time of Bishop Nicolò of Brno (1338-1347) became the symbol of the Episcopal Principality of Trento and even of the Commune of Trento, and at present has been adopted as “stemma” of the “Provincia Autonoma di Trento”
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
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
