Analisi archeozoologica e tafonomica preliminare di un campione faunistico dal sito di Ponticelli di Malalbergo
No full textI livelli relativi alle prime fasi di vita dell’abitato portato in luce in via Ca’ Bianca, datati al passaggio fra il Bronzo medio 3 e il Bronzo recente 1 (1450-1225 a.C.), hanno restituito un consistente numero di reperti faunistici, a testimonianza di un’intensa frequentazione dell’area destinata, in queste fasi, a scopi abitativi. Al momento sono stati analizzati in dettaglio circa 150 frammenti ossei selezionati in maniera mirata, ed in accordo con le indagini condotte sugli altri reperti archeologici, da tutti i contesti indagati (sito 5A, 5B e 5C) durante le operazioni di scavo. Questa analisi di dettaglio, seppur condotta su di un ristretto ma significativo campione faunistico, ha permesso però precise valutazioni tafonomiche che hanno contribuito alla ricostruzione di un piccolo tassello dell’economia del sito che si mostra, già da queste prime informazioni raccolte, spiccatamente legato alla cultura terramaricola, tipica di tutta la Pianura Padana
Subsistence of early anatomically modern humans in Europe as evidenced in the Protoaurignacian occupations of Fumane Cave, Italy
No full textDocumenting the subsistence strategies developed by early modern humans is relevant for understanding the success of their dispersal throughout Eurasia. Today, we know that there was not a single colonization event and that the process was progressive while coping with the MIS3 abrupt climatic oscillations. Modern humans expanded into the continent by adapting to different topographic situations and by exploiting resources in diverse ecological niches. The northern part of Italy is one of the first European regions where early modern humans are documented. Here, we present the subsistence regimen adopted by the Protoaurignacian groups in two different levels in Fumane Cave based on archaeozoological data. New radiocarbon dates confirm an overlap between Uluzzian and Protoaurignacian occupations, around 42 and 41,000 cal BP, and reveal that modern humans occupied the cave from GI10 to GS9, the last level coinciding with the Heinrich Event 4. The data indicate seasonal site occupations during late spring/summer and that prey exploitation was focused mostly on ibex and chamois, killed in nearby areas. The whole faunal assemblage suggests the presence of early modern humans in a cold environment with mostly open landscapes and patchy woodlands. The estimation of net primary productivity (NPP) in Fumane, compared with other contemporaneous Italian sites, reflects how the NPP fluctuations in the Prealpine area, where Fumane is located, affected the biotic resources in contrast to known Mediterranean sites. From a pan-European perspective, the spatiotemporal fluctuation of the NPP versus the subsistence strategies adopted by Protoaurignacian groups in the continent supports rapid Homo sapiens dispersal and resilience in a mosaic of environments that were affected by significant climate changes

Subsistence strategies during the Gravettian in the rock shelter of La Vina(Asturias, N Spain)
No full textThe rock shelter of La Vina, located on the northern Atlantic coast of the Iberian Peninsula, contains a rich archaeological sequence dated from the Mousterian to the Magdalenian. This site preserves an extended Gravettian occupation where a diversified assemblage of fauna, lithic and bone tools has been attested. In this
paper, we undertake the archaeozoological and taphonomic study of the macromammals found in the Gravettian levels X and IX of the Western Sector, recovered during the campaigns directed by Fortea between 1987 and
1992. The taphonomy indicates a high presence of fire-altered bone elements and butchery marks related to
ungulate skinning and disarticulation activities, with a low presence of carnivore modifications, being Cervus
elaphus, followed by Rupicapra rupicapra and Capra pyrenaica the most common taxa, therefore confirming the
anthropogenic origin of the bone assemblage. Given the high fragmentation of the infantile remains identified, a
biomolecular study by Zooarchaeology by Mass Spectrometry (ZooMS) was carried out to increase the taxonomic
data and unravel the hunting strategies and site seasonality. Proteomic results revealed a high presence of
newborn red deer and ibex, thus suggesting females herd captures during late spring/early summer
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
