Conditioning of the raw materials on discoid exploitation strategies during the Early Middle Palaeolithic: the example of Payre level D (South-East France)
No full textIn the last decades, a growing attention was paid toward the exploitation of other lithic raw materials than flint. In this context, the lithic assemblage of Payre level D, dated to the end of the MIS 6, offers the opportunity to make some considerations about the modalities of a discoid technology on various lithic raw materials. Payre is a very well-known Middle Palaeolithic site located on the right edge of the Middle Rhône valley. Three main archaeological levels attest an intense human frequentation of the site between the end of MIS 8 and the beginning of MIS 5. The rich faunal and lithic assemblages, recovered during systematic excavations from 1990 to 2002, have been deeply analysed for a precise understanding of the site formation processes and the modalities of the human occupation of the area. The exploitation of different local and semi-local raw materials made Payre an interesting case to observe how lithic resources with different petrographic characteristics were exploited by the Neanderthal groups. The present work aims to observe how the lithic raw materials have affected the discoid reduction sequences. This knapping method is widely attested in archaeological level D, the last large phase of human occupation at Payre. Among the different raw materials exploited (flint, vein quartz, quartzite, basalt and limestone), the discoid method is just applied on flint and vein quartz. The new technological analysis carried out focuses for the first time on the characteristics of the discoid technology present in level D and on the differences in discoid reduction sequences depending on the raw materials. The results indicate some expedients used to apply discoid reduction strategies on vein quartz and adapt this technology to the features of a coarse-grained stone. The use of such expedients testifies a large capability to manage not only the raw materials but also of the discoid method itself. Results allow to make considerations on some of the criteria proper to the technological definition of the method

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
Bioglio, Valle Mosso, Valle San Nicolao, Pettinengo. Alta Valsessera e valle Dolca. Frequentazione preistorica di alta quota: risultati della campagna di ricognizione
No full textNel luglio 2013 è stata effettuata una campagna di ricognizione di cinque giorni nell’ambito del progetto “Survey Alta Valsessera”, volto a individuare eventuali occupazioni mesolitiche nel territorio alpino biellese, sotto la direzione scientifica della Soprintendenza per i Beni Archeologici del Piemonte e del Museo Antichità Egizie in collaborazione con l’Associazione culturale 3P-Progetto Preistoria Piemonte e il DocBi-Centro Studi Biellesi. Questa vallata è oggetto del pluridisciplinare “Progetto alta Valsessera”
promosso da alcuni decenni dal DocBi, al quale la Soprintendenza
per i Beni Archeologici del Piemonte ha in passato partecipato con le ricerche sulle fortificazioni di fra’ Dolcino di inizi XIV secolo, sugli impianti siderurgici di XVIII secolo e su una trappola per lupi
