Nascita e sviluppo del distretto biomedicale mirandolese: un excursus storico-economico (1962-2012)
No full textQuesto capitolo mostra che il distretto biomedicale di Mirandola è sorto e si è sviluppato grazie ad una combinazione originale di due settori manifatturieri che già erano presenti nella zona o in territori adiacenti: la meccanica e la lavorazione delle materie plastiche.
Il distretto nacque negli anni Sessanta su iniziativa di un farmacista della zona, Mario Veronesi, che diede vita ad una serie di aziende, cedute dopo pochi anni a multinazionali, e a processi di spin-off, che alimentarono la proliferazione di piccole imprese biomedicali nella zona, sia finali che di subfornitura. A tale processo si accompagnò, a partire dalla metà degli anni Settanta, lo sviluppo di un know how locale distintivo, che consentì di abbandonare la produzione per imitazione di prodotti statunitensi.
I caratteri peculiari del distretto biomedicale mirandolese – che lo distinguono da molti altri distretti industriali italiani sono la specializzazione high tech e la presenza precoce, sin dalle origini, di grandi multinazionali che hanno rilevato le imprese locali più promettenti. Le multinazionali hanno rappresentato un ponte tra il distretto e i mercati globali, in quanto, grazie alla loro organizzazione commerciale, i prodotti fabbricati a Mirandola hanno potuto essere venduti in tutto del mondo. Esse, inoltre, hanno consentito alle imprese mirandolesi di disporre di risorse adeguate per la ricerca e sviluppo di nuovi prodotti e di realizzare collaborazioni con istituzioni di ricerca ed ospedali esterni all’ambito local
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

No full textAppropriate 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
