STORIOGRAFIE ITALIANE DEL XII SECOLO. Contesti di scrittura, elaborazione e uso in una prospettiva comparata
Full text linkhe essays collected in this volume are dedicated to the pragmatic dimension of the writing of history in 12th-century Italy. All the contributions can be read by following a few guiding questions: why and by whom were chronicles written? In what spheres and with what objectives did they circulate? How were they used in the political arena? Through an innovative comparative perspective, which holds southern and central-northern Italy together, the main objective of the volume is to problematise, by means of concrete case studies, social and political significance of history writing in 12th-century Italy
Dai da Burcione alla Brina: diverse letture intorno a un castello
No full textIn Lunigiana, nonostante l’alta densità di castelli per km quadro visibili in loco e attestati dalle fonti, sono stati fatti pochi scavi archeologici e campagne di ricognizione programmati. Questo è un ovvio ed evidente svantaggio per chi studia il territorio. Le rare volte in cui allo studio della documentazione si è accompagnata un’indagine sul campo, i risultati sono stati quasi sempre di portata rivoluzionaria rispetto alle conoscenze pregresse che la comunità scientifica poteva vantare su questa piccola regione storica. Lo confermano le recenti indagini sulla Brina, castello e insediamento lunigianese attestato da una cospicua documentazione, noto per essere menzionato dalla cosiddetta “pace di Dante” del 1306 e fortunatamente oggetto di numerose campagne di scavo, che hanno messo in luce le varie fasi del castello e le tracce dell’insediamento anteriore. La comparazione dei dati emersi dalle indagini archeologiche con le attestazioni documentarie ha consentito non solo di avanzare ipotesi concretamente fondate e nuove sull’evoluzione degliinsediamenti e sul processo di incastellamento in Lunigiana, ma anche di rivedere gli studi sulla famiglia dei suoi domini, i da Burcione
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
Il sogno di Guido. Una vecchia geografia per un mondo nuovo
Full text linkAlberto Cotza dimostra come nella Pisa del XII secolo la produzione di opere storico-geografiche non si limitasse a una descrizione del presente geografico, ma facesse invece ampio uso di opere precedenti di almeno cinque secoli per proporre il proprio “orizzonte di attesa politico” e rivendicare il predominio sul Mediterraneo
Pace di Corso e gli altri mercanti. Pirateria, società e istituzioni a Pisa nella seconda metà del XII secolo
No full textNel corso della seconda metà del XII secolo il comune di Pisa definì la pirateria come un insieme di comportamenti illeciti, che potevano essere puniti dai tribunali cittadini. Il saggio analizza le implicazioni sociali e politiche di questa definizione, a partire dalla corretta contestualizzazione di un ben documentato assalto pisano al porto di Tunisi dell'estate del 1200. L'autore propone di considerare la definizione formale della pirateria come un fenomeno sociale. Questa definizione è al cuore del processo che portò il comune a diventare un'istituzione politica in grado di covernare l'accresciuta complessità sociale della città.In the second half of the 12th century the commune of Pisa defined piracy as a set of illicit behaviours, which could be punished by the city courts. This essay analyzes the social and political implications of this definition, starting from the detailed contextualization of a well-documented Pisan assault of the port of Tunis in the summer of 1200. The author suggest considering this formal definition of piracy as a social phenomenon. It aims to establish the commune as a political institution and to control the increased social complexity of the city
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
