La necropoli altomedievale di Castel Trosino. Con un contributo sulle monete di Emanuela Spagnoli
No full textI volumi raccolgono l’insieme della documentazione archeologica rinvenuta presso il sito di Castel Trosino (Ascoli Piceno), che è oggetto di scavo fin dal 1893. Il primo volume si compone di un ampio saggio introduttivo, che rende conto della storia degli scavi e delle ricerche succedutesi in più di un secolo di studi su questo territorio, e del preciso e dettagliato catalogo dei reperti. Il secondo volume riporta le tavole relative ai reperti e offre un ricco apparato fotografico a colori che permette di analizzare ogni dettaglio degli oggetti più importanti. Il contributo sulle monete completa la ricca e complessa offerta scientifica del testo

Portus: An Archaeological Survey of the Port of Imperial Rome
No full textIn AD 42, the Emperor Claudius initiated work on the construction of a new artificial harbour a short distance to the north of the mouth of the Tiber. The harbour facilities were enlarged at the instigation of the Emperor Trajan at the beginning of the second century AD, and Portus remained the principal port for the City of Rome into the Byzantine period. The surviving archaeological remains and comments by ancient sources make it clear that Portus lay at the heart of Rome's maritime façade. As well as being a key Mediterranean centre for passengers and for the loading, unloading, transshipment and storage of products from across the Empire, it was also designed to make an ideological statement about the supremacy of Rome in the world. Portus is, thus, of key importance to understanding Rome and her relationship to the Empire. The project that forms the subject of this book was designed to use non-destructive techniques of topographic and geophysical survey in combination with systematic surface collection to provide a new understanding of the plan of Portus. The work was undertaken between 1997 and 2002 as a collaboration between the Soprintendenza per i Beni Archeologici di Ostia, the British School at Rome, and the Universities of Southampton, Durham and Cambridge. This volume presents the full results of the survey and uses them as the basis for a re-evaluation of the whole port complex. The geophysical survey results are interpreted in the context of earlier work at the site in order to offer new perspectives on the character and development of the site
La documentazione ceramica dell'Italia centro-meridionale nell'alto medioevo: quadri regionali e contesti campione
No full textAnalisi di ceramiche provenienti da tre contesti altomedievali: Roma, Crypta Balbi (VIII secolo), Otranto, area portuale e San Vincenzo al Volturno (Molise), fasi di IX-XI secolo. I contesti sono stati scelti, tra le rare stratificazioni di questo periodo, con un duplice scopo: creare delle prime serie ceramologiche e mettere a confronto ambiti diversi per funzione e posizione geografica
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
