Le anfore e gli opercula
No full textThe oldest example among the amphorae found in 1987, in the Corte Abate Elia, is datable to the middle of the 3rd century BC, and is of ‘Ionian-Adriatic’ production. It is residual in that context, as are the ‘Italic’ products of the 2nd - 1st centuries BC and those imported from North Africa in the Early Imperial period and Late Antiquity. The bulk of the material consists of Byzantine and Mediaeval amphorae. Among the opercula are some mould-made pieces and some turned on a fast wheel
Cittadella Nicolaiana - 1 archeologia urbana a Bari nell'area della basilica si san Nicola. saggi 1982-1984-1987
Full text linkThis paper is a first summary and update on the data of the graves and skeletal remains found in St. Nicholas Citadel (Bari, South Italy) during the excavation work of 1982, 1984 e 1987. In particular, it deals with the anthropological and paleopathological study of human bones, updating methods and comparisons, and provides a preliminary picture of the sample of individuals. Particular attention is focus on the craniometric investigation
I contenitori da trasporto e la circolazione delle merci
No full textThe amphorae discovered in the Cittadella Nicolaiana (1982, 1984, 1987) are assessed in relation to previous discoveries made in Bari and its hinterland, and elsewhere in the Puglia. Particular attention is paid to coastal and underwater sites so as to obtain evidence for reconstructing trade routes, and for assessing the capacity of the port of Bari. The trade network (in wine, oil and salsamenta) extended over a wide time span from the Hellenistic period to the Middle Ages
Le anfore, gli opercula e i “Late Roman Unguentaria”
No full textThe amphorae found in the 1982 and 1984, in Piazza San Nicola, are related to ‘Italic’ products and to a group imported from Africa and from the East Aegean, datable from the mid-2nd century BC to the 12th/early 13th century AD. The amphorae of the early and full Middle Ages are quantitatively significant. Opercula made on a fast potter’s wheel and one copy of a Late Roman Unguentarium of the Late Antique period are also documented
Sull’epigrafia cristiana di Roma. Bilanci e prospettive alla luce di un trentennio di ricerche (1993-2022)
No full textA synthesis about the last thirty years of search and studies of Christian epigraphy of Rome in Late Antiquity, and a glance to the future perspectives of the discipline
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
