Late Epigravettian and Mesolithic foragers of the eastern Alpine region: Animal exploitation and ornamental strategies at Riparo Biarzo (Northern Italy).
No full textThe eastern Alpine region of Italy represents a well-known area with regards to the study of Late
Pleistocene and Early Holocene forager adaptations in the whole peninsula. Caves, shelters and open-air
sites, which are numerous in this region, have yielded traces of human re-peopling from mountaineous
environments since the Late Glacial and until the Early Holocene. However, the archaeological record of
the region lacks evidence about long lasting forager occupations. Exceptionally for the eastern Alpine
sector, Riparo Biarzo (Natisone Valley, Julian Prealps) has yielded important evidence of continuous
forager frequentation from Late Pleistocene to Early Holocene.
The authors discuss the results of the analyses of animal remains and shell ornaments recovered in the
Late Epigravettian and Mesolithic units of the site and their significance for understanding continuity and
changes in the subsistence and symbolic strategies during these periods in the region.
Archaeological data indicate an abundance of wild boar remains during both the Late Pleistocene and
the Early Holocene at Biarzo, which makes hunting strategies at this site unique with regards to other
contemporary contexts of the eastern Alpine region. Also, modalities of selection, production and use of
ornaments in the same periods reveal the existence of established exchange networks, mobility strategies
and connectivity between the eastern Alpine and the North Adriatic regions during the Late
Epigravettian and throughout the Mesolithic

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
L'impiego dei rimontaggi ossei in due realtà del Paleolitico Medio: Abric Romani e Riparo Tagliente
No full textRiassunto - Lo studio e l’applicazione dei rimontaggi ossei, tecnica impiegata in archeologia a partire dagli anni ‘70 (De Mortillet 1881, 1894; Spurrell 1880) si basa sulla ricostruzione di elementi rotti o fratturati, al fine di stabilire i processi di formazione, risolvere questioni legate allo spostamento verticale dei resti, valutare i processi post-deposizionali (Hofman 1981, 1986; Van Noten et al. 1978; Villa 1982; Villa et al. 1985, 1986) e riconoscere le aree di attività dei neandertaliani (Larson, Ingbar 1992; Leroi-Gourhan, Brezillon 1972). Nel presente studio si propone l'applicazione di questa metodologia nei livelli musteriani I e Ja dell’Abric Romaní (Capellades, Spagna) e 37 di Riparo Tagliente (Verona, Italia). Dopo aver determinato la modalità di sfruttamento dei taxon su base tassonomica e tafonomica, i rimontaggi vengono effettuati in questo modo: analisi dei resti per singoli quadrati (differenziazione dei resti secondo taxon e taglia), per quadri adiacenti e globalmente, analizzando tutti i quadrati dell'area indagata. Una volta effettuato il lavoro pratico, tutti i dati vengono analizzati ed elaborati, per ottenere la distribuzione spaziale dei livelli indagati. Questa metodologia, anche grazie alla correlazione con i focolari e le strutture identificate, permetterà di valutare le differenze tra i pattern occupazionali, le attività di sussistenza, il livello di complessità dei gruppi, le aree domestiche, il periodo e la durata dell’occupazione, all'interno delle due realtà mediterranee.Summary - The study and the application of bones refitting, technique adopted in archaeology since the 70's, (De Mortillet 1881, 1894; Spurrell 1880) is based on the reconstruction of broken and fractured elements to determine formation process, to resolve question about remains vertical movements, to evaluate post-depositional process (Hofman 1981, 1986; Van Noten et al. 1978; Villa 1982; Villa et al. 1985, 1986) and to recognize Neandertal's activities areas (Larson, Ingbar 1992; Leroi-Gourhan, Brezillon 1972). The aim of this paper is to present the application of this metodology in Mousterian levels I and Jb of Abric Romani (Capellades, Spain) and 37 of Riparo Tagliente (Verona, Italy). Once you determine taxon exploitation, throught an anatomic, a taxonomic and a taphonomic study, refittings are made in this way: remains analysis for each squares (differentiation of anatomical elements depending on taxon and size), by closest square and in overview, by analysing all the squares of the area (considering greatest accumulation). Once the refittings are carried, all the data are analysed and processed to obtain the spatial patterns of investigated levels. Thanks to the correlation with hearths and structures identified, this kind of analysis, applied in two mediterranean sites, will evaluate the differences between occupational patterns, subsistence activities, domestic areas, level of group's sophistication and duration of employment
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
