Hoarding unworked flints within humid microenvironments. New evidence from the Mesolithic of the Southern Alps
No full textA hoard composed by six blocks of flint has recently been discovered inside a peat bog on the Cansiglio Plateau (Venetians Pre-Alps). the blocks were collected in sources situated 25 km far from the plateau and in almost all cases they were tested before being carried onto the site. Owing to the preliminary state of the fieldwork, only a few hypotheses regarding the significance of the hoaerd can be proposed here, above all in relation to an adiacent Epigravettian open-air site. comparisons with other hoards in Europe highlight the peculiarity of this kind of structure
Épigravettien récent et Mésolithique ancien dans un contexte préalpin: les données du haut Plateau du Cansiglio (Italie du Nord)
No full textLes auteurs présentent les résultats préliminaires de recherches entreprises sur le plateau de Cansiglio (Préalpes de la Vénétie) et livrent quelques réflexions sur les occupations humaines de ce secteur pendant l'Holocène ancien. Plusieurs sites sont connus mais seuls Palughetto (Epigravettien) et Casera Lissandri (Sauveterrien) ont
étéfouillés. Ce dernier, situé à 1060 m d'altitude, représente un cas inéditpour le modèle d'occupation mésolithique du sud des Alpes.
Les observations archéologiques nous permettent d'aborder plusieurs aspects:
— mode d'occupation;
— approvisionnement ou circulation des matières premières lithiques et leur exploitation ou mise en réserve surplace;
— fonction du site (à travers la structure de l'industrie lithique)
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
