Scraping hide in the early Upper Paleolithic: insights into the life and function of the Protoaurignacian endscrapers at Fumane cave
No full textEndscrapers are specialized tools that are usually recovered in great quantities in every Upper Paleolithic site in Europe. Although they make their first ephemeral appearance in the Middle – late Middle Paleolithic transitional technocomplexes, endscrapers commonly appear in tool-kits from initial and early Upper Paleolithic traditions onwards. Nevertheless, endscrapers and, in general, domestic tools have attracted relatively little attention in debates revolving around the significance of technological change, tool-function and tool-specialization after the end of the Middle Paleolithic. With the aim to overcome this paucity of information, here, we present the results of a techno-functional study performed on the large endscraper assemblage recovered from the early and late Protoaurignacian layers at Fumane Cave in northeastern Italy. We analyzed these artefacts using technological, morpho-metrical, typological and functional approaches. Despite the large morphological variability, use-wear traces reveal functional consistency and high levels of specialization for these tools. Almost all the use-wear traces we recorded developed from hide working with transverse motion. Moreover, we find no evidence that endscrapers were involved in the production of bone and antler tools during the late Protoaurignacian. Macroscopic and microscopic wear on the lateral edges of tools point to a considerable number of hafted endscrapers, which implies systematic time investment and planning depth. Comparison with the few endscrapers from transitional industries that have been analyzed highlights marked differences in the production, morphology and use of these tools and reinforces our view of the Aurignacian as a complex not directly related with preceding European traditions

Projectile points vs tools for dental treatment? From the impact fracture analysis to a new perspective of research: the case of Riparo Villabruna (Belluno – Italy)
No full textRiparo Villabruna (Sovramonte – Belluno – Italy) is a small shelter with Final Epigravettian lithic industry at 500m asl, located in the Dolomites of Veneto region and excavated in the 1988-89. The archaeological site is famous for the discovering of a burial, found during roadworks. The buried individual was an adult male of 25 years old and 170cm tall, recognized as a hunter-gatherer for the presence of funerary goods (a bone point, a backed knife, a flint blade and a core, a siltstone pebble and a lump of unidentified material). Direct radiocarbon dates in addition to dated charcoals found in the burial pit place the burial in the interval 14,400 – 13,800 cal yr BP. The dentition of this individual also documents the earliest evidence of dental caries intervention on a Late Upper Paleolithic modern human specimen. Using SEM, striations were observed that were interpreted as deriving from the manipulation of a large occlusal carious cavity of the lower right third molar, which also was confirmed experimentally. Those striations appear to have been produced ante-mortem with pointed flint tools during scratching and levering activities.
The results will be presented of a macro-fracture analysis that has been performed on part of the assemblage focused on an evaluation of the presence of impact-related fractures and the potential presence of projectile points in order to understand the function of the archaeological site. Some backed points proved to show a differing wear pattern and it was questioned whether these traces could correspond to dental caries intervention. In order to test this hypothesis, experiments were performed in combination with use-wear analysis to evaluate whether the observed damage patterns could indeed be caused by scratching enamel and dentine in view of dental treatment
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
