Vetro e alimentazione fra Tardoantico e Medioevo: riflessioni a partire da alcuni casi di studio della Puglia centrosettentrionale
No full textLe indagini condotte negli ultimi anni in alcuni contesti urbani e rurali della Puglia centro-settentrionale (Canosa, Ordona, San Giusto, Faragola, masseria Pantano, San Lorenzo in Carmignano e Montecorvino) stanno consentendo di ampliare l’orizzonte delle conoscenze sui vetri tardoantichi, altomedievali e medievali, sostanzialmente poco noti in relazione al comparto territoriale in esame. Nonostante alcuni progressi registrati negli ultimi anni, emerge una sostanziale carenza di studi sistematici e di progetti di ricerca mirati; i materiali vitrei editi, rinvenuti in contesti stratigrafici affidabili, sono estremamente limitati. Parallelamente ad un ampio progetto archeometrico incentrato su indicatori di lavorazione, vasellame, tessere musive e sectilia in pasta vitrea, sono stati effettuati studi su aspetti morfo-tipologici finalizzati all’elaborazione di un atlante crono-tipologico delle forme vitree dal III-IV al XV sec. d.C.
In questa sede ci soffermeremo sugli aspetti funzionali dei manufatti vitrei, cercando di approfondire alcune linee di ricerca proposte in passato e di introdurre elementi di novità, alla luce dei dati emersi dalle ricerche più recenti e dal riesame di alcuni contesti editi significativi. Il contributo infatti si propone di esaminare, attraverso un’analisi integrata dei reperti vitrei e delle suppellettili da mensa di altro materiale, il ruolo e le funzioni assegnati al vetro nell’articolazione di un servizio da tavola, verificandone anche le modificazioni fra Tardoantico e Medioevo.
In età tardoantica e medievale, il repertorio morfo-tipologico del vasellame utilizzato sulla mensa, sia pur semplificato e polarizzato su alcuni tipi funzionali, continua ad apparire abbastanza articolato.
Si tenterà di proporre una lettura diacronica dei differenti tipi di corredi domestici documentati, presentando anche il vasellame ceramico coevo, proveniente dalle medesime stratigrafie. Si dispone infatti di contesti significativi relativi a cucine e a magazzini/dispense di abitazioni urbane e rurali che hanno restituito, accanto a nuclei cospicui di vetri, quantità consistenti di ceramiche da cucina, da mensa e da dispensa e un considerevole campione faunistico e archeobotanico.
Si cercherà di capire se la sostanziale identità tra produzioni urbane e rurali, emersa dagli studi ceramici, si rifletta anche nel vasellame vitreo o se il diverso status sociale possa aver influenzato le caratteristiche dei corredi domestici, seguendo l’evoluzione del trend da età tardoantica a età medievale. Più specificatamente si tenterà di cogliere eventuali analogie o differenze nei tipi di vasellame vitreo documentato nelle cucine e sulle tavole delle élites cittadine e rurali e in quelle dei ceti subalterni, anche con l’obiettivo di verificare se la caratterizzazione morfo-tipologica delle suppellettili possa essere ritenuta un indicatore di differenziazione sociale, pure in rapporto a usi alimentari socialmente diversificati
Perle Golasecchiane in materiale vetroso dai dintorni di Como
No full textWe will expound upon protohistoric vitreous material beads (faience, glassy faience and glass) from the Como area (eastern facies of the Golasecca culture, IX-IV centuries BC), that belong to the collections of the museum “P. Giovio” in Co-mo (Italy). Here, typological and technological aspects are examined: the research involves systematic archaeometric analy-ses, carried out by the Università di Padova - Dipartimento di Geoscienze. The aim is to point out the spread and the diffusion of glass beads, from the point of view of the well-known goods circu-lation framework in the Como area, their function and their cultural meaning
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
Le capselle paleocristiane di Mariano Comense
No full textIn 1574, the demolition of the altar of the Romanesque baptistery of St. John the Baptist in Mariano Comense led to the discovery of a stone capsule in the form of a sarcophagus, now kept in the parish archives; the reliquary contained fragments of figured silver-leaflets, the remains of a bone box, and textile fragments. The contribution reconsiders the capsella and its contents, also proposing a reconstruction of the bone cassette to which the silver laminettes were attached
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
