I bronzi degli Etruschi e dei Celti nella Valle dell'Idice
No full textIl volume contiene 11 articoli di archeologi e restauratori consacrati al tema dei manufatti di bronzo usciti dalle ricerche archeologiche nella valle dell'Idice e trovati in contesti funerari all'interno di necropoli di comunità celtico-etrusche del settore appenninico tosco emiliano, a sud-est di Bologna. Vasellame, parures, specchi, utensili caratterizzanti il periodo del IV e III sec. a.C. e restaurati per uno studio e per un'esposizione permanente nel Museo "L. Fantini" a Monterenzio, sono l'occasione di ricucire i legami tra l'Etruria toscana e quella padana nel corso dei duecento anni che corrispondono all'egemonia dei Celti Boi.
Studi tecnologici permettono di ricostruire la catena opeerativa che hanno portato alla fabbricazione antica di alcuni manufatti (vasi a "gabbia" e kyathoi "a rocchetto")
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
Cavalli in tombe - Tombe di cavalli in necropoli lateniane d'Italia
No full textSintesi relativa al tema della presenza di tombe di cavalli nell'area spaziale di necropoli riferite ai Celti d'Italia. Alla presenza di scheletri si associa o si sostituisce quella di elementi di bardatura di cavallo o di elementi metallici pertinenti alla struttura (generalmente le ruote) del carro. Sono esaminati i casi di presenze analoghe durante la prima e seconda età del ferro e per l'età di La Tène i territori dei Cenomani e dei Senoni; nel territorio dei Boii questa pratica per il momento non sembra attestata
