Indicatori di pratiche cultuali nel sito fortificato dell’età del Bronzo di Portorusso (Otranto-Le): evidenze archeologiche e analisi dei residui organici
No full textLe ricerche condotte tra il 2015 e il 2016 nell’abitato fortificato di Portorusso hanno consentito di mettere in luce un ambiente coperto localizzato a ridosso del muro difensivo, all’interno del quale, in prossimità di piastre da focolare, erano stati deposti oggetti particolari come contenitori ceramici miniaturistici, ornamenti in osso, manufatti in lega di rame o conchiglie. L’analisi integrata delle evidenze archeologiche, insieme alla caratterizzazione chimica dei residui organici contenuti all’interno di cinque recipienti ceramici ha consentito di chiarire alcuni aspetti funzionali di questo ambiente suggerendo una sua destinazione cultuale
Radiocarbon dates and XRF analyses from two prehistoric contexts in the Badisco area (Otranto –Le)
No full textWe presents the results of a radiocarbon dating and XRF (X-ray Fluorescence) measurements performed on organic samples and pottery recovered from “Grotta dei Cervi” and “Cunicolo dei Diavoli” caves, two important prehistoric contexts located in the area of Porto Badisco, Southern Italy. The radiocarbon dating analyses allowed to assess the funeral use of the “Cunicolo dei Diavoli” cavity during the Copper Age and to clarify the long debated chronology of one of the pottery style widely diffused in Southern Italy during the Neolithic and namely the Macchia a Mare/Zinzulusa style. This was obtained through the analysis of a charcoal fragment extracted from a jug ascribed to this ceramic style. At the same time XRF (X-ray Fluorescence), non destructive analyses allowed to identify as cinnabar a red pigment used to decorate pottery recovered in the “Grotta dei Cervi” and dated to the 5th millenium B
THE COPPER AGE MOUND NECROPOLIS IN SALVE, LECCE, ITALY: RADIOCARBON DATING RESULTS ON CHARCOALS, BONES, CREMATED BONES, AND POTTERY
Full text linkArchaeological surface surveys carried out near Salve in southern Italy led to the identification of about 90 stone mounds spread over an area of about 100 ha. Systematic archaeological investigations allowed to identify the mounds as funeral structures with some having megalithic features. In the necropolis, both the inhumation and cremation rituals are evident, in some cases within the same mound. This article presents the results of an accelerator mass spectrometry (AMS) radiocarbon dating campaign carried out on different kinds of samples recovered from several structures: unburned and cremated bones, charcoals, and organic residues extracted from pottery sherds. The results allowed to assess the chronology of the site and to shed new light on the different funeral practices in Copper Age southern Italy
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
Radiological tooth/pulp ratio in canines and individual age estimation in a sample of adult neolithic skeletons from Italy
Full text linkThe estimation of an individual's age at the time of death is one of the most important components in anthropological studies and is the basis for demographic studies on ancients. However, the different methods commonly used in anthropology for adult age estimation at death provide results with a high level of uncertainty. The consequence is the inability to develop demographic studies with a good degree of reliability. A non-destructive method currently available is the analysis of the apposition of secondary dentine on which Cameriere's method is based
