La terramara di Pragatto (BO): primi dati sull’organizzazione spaziale del sito
No full textIl lavoro intende presentare i primi risultati relativi all’analisi dell’organizzazione spaziale del villaggio terramaricolo di Pragatto. Nello specifico, verranno presi in esame sia l’assetto generale del sito, sia la distribuzione interna delle strutture in una fascia, ampia circa 7.000 mq, indagata compiutamente tra il 2016 e il 2017. In tale area lo scavo ha raggiunto, sia a est che ad ovest i limiti
del villaggio: verso ovest è stato possibile ipotizzare l’esistenza, già nell’età del bronzo, di un corso d’acqua ad oggi coincidente con il Rio Carpineta, a est è stato invece messo in luce un più complesso e articolato sistema di delimitazione perimetrale, in cui, oltre al fossato, si sono individuati lembi di colluvio del terrapieno e, verso l’area abitata, tracce di gabbionature lignee confrontabili
con quelle scoperte dal Pigorini a Castione Marchesi.
Grazie all’analisi informatizzata dei dati relativi alle buche di palo rinvenute sul suolo basale del villaggio è stato, poi, possibile
giungere ad una prima ipotesi di ricostruzione della planimetria e distribuzione delle capanne, sulla base anche di quanto noto nei siti coevi quali Poviglio, Gaggio, Montale.
Sulla base di tali osservazioni è stata, infine, effettuata un’ipotesi per quanto riguarda la viabilità interna al villaggio e il suo rapporto con l’area perimetrale del sito, includente le tracce delle strutture lignee (“gabbioni”) e il fossato che delimita l’abitato ad oriente. In particolare, sono stati identificati dei tracciati interni che corrono in senso SSO-NNE, mentre un altro tracciato, perpendicolare
ai primi, sembra raccordarsi al varco che interessa ad est la struttura dei gabbioni, in corrispondenza di quello che potrebbe interpretarsi come uno degli accessi al villaggio.The work intends to present the first results of the excavation conducted in the Terramara di Pragatto between 2016 and 2017 and illustrate the spatial organization of the site. The area under investigation corresponds to a wide strip of about 7,000 square meters coinciding with the southern portion of the built-up area.
Excavation reached the settlement’s limits toward both east and west. A complex and articulated system of perimetric delimitation was defined in the eastern side, which included a moat, the edges of the embankment’s colluvium, and traces of a palisade and wooden gabions towards the inhabited area. For what concerns the stratigraphy the archaeological deposit is fully preserved
starting from levels dating to the Middle Bronze Age 3–early Late Bronze Age and it has two distinct phases of well-characterized and regularly spaced heaped dumps. The basal level revealed the existence of a first settlement phase, which, in the explored area, seems having included no dwellings, while long palisades delimitating empty areas have instead been found.
Thanks to the computerized analysis of the data relating to the post holes found on the basal soil it was then possible to arrive at a first hypothesis of reconstruction of the spatial organization of the village with particular regard to internal viability and its relationship both with the distributions of the huts and with the articulated system of perimetric delimitation

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
