La seconda vita di Cassiodoro e la "Collectio Avellana"
No full textFrom 503 to 537/538 Cassiodorus was a senator and politician in Ravenna.There he pursued a long and prestigious career in the loyal service of the Ostrogothic kings. He gave up politics between 538 and 540, when he was around 55 years old. It is not certain where Cassiodorus resided in the decade 538-549. In 550 he appears as vir religiosus in the retinue of Pope Vigilius who was residing in Constantinople and was debating with Emperor Justinian (the dispute concerning the ‘Three Chapters’). Contrary to the opinion of A. Momigliano and some scholars to date, we assume that Cassiodorus abandoned politics for good around 537/538 and that towards the end of the first phase of the Gothic War the former dignitary of the Ostrogothic kings placed himself under the tutelage of Pope Vigilius: in this way he escaped the reprisals of the Byzantines and Ostrogoths. Cassiodorus had noambitions of reintegration into the ruling elite and became vir religiosus in thepope’s retinue, whose strategy he espoused. He followed Vigilius to Constantinople, not as a fugitive, nor as a prisoner, but as one of pope’s collaborators and supporters. Finally, we suggest that between 545 and 547 Cassiodorus was collecting in Rome the selection of documents that were to become the Collectio Avellana, in the aim of supporting the pope in the dispute of the ‘Three Chapters’ in the East. The Collectio was not intended for publication, and after the return of the defeated pope from Constantinople the Collectio lost interest for its author and was neither updated nor published
Dal manoscritto medievale ai modelli tardoantichi. Indizi nel codice V della Collectio Avellana
No full textIl presente lavoro intende offrire un piccolo contributo alla riflessione sulla
fisionomia originaria dei modelli librari e documentari della Collectio Avellana;
un riesame del paratesto dei dispositivi di emanazione imperiale presenti
nel codice V, confrontato con i materiali tardoantichi superstiti (papiri
documentari, manoscritti tardoantichi delle codificazioni), anche di recente
acquisizione, permette di verificare la sostanziale regolarità delle soluzioni
di impaginazione adottate e di ipotizzare, per alcuni testi singoli e/o dossier
più uniformi graficamente, più fasi di copia che per altri, più conservativi
nella ‘mise en page’ e nell’uso di strategie distintive

No full textGli exceptores fra tarda antichità e alto medioevo. Aspetti istituzionali, sociali e culturali
No full textThis contribution aims to offer a picture of the "exceptores" and their transformations between Late Antiquity and the early Middle Ages (fifth-eighth centuries). After some general considerations concerning not only Italy, but also Gaul and Egypt, the discussion focuses then on Ravenna. The core of the investigation consists of a complete re-examination of the so-called 'Ravenna papyri". Such documents – and the "editiones gestorum" in particular – are here used to illustrate social profiles, institutional links as well as cultural and professional skills of the "exceptores". From there, the article tries at the end to reflect on the possible contribution that the documentary practices of the "exceptores" can offer to a better understanding of the "Collectio Avellana"

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
