La storia degli studi nei gessi emiliano-romagnoli (XV-XIX secolo). Un primato mondiale
No full textThe article analyses, in a diachronic perspective, the history of the studies of Gypsum karst areas in Emilia-Romagna Region (Northern Italy), from its beginnings in the late 15th century to the 19th century. What emerges is a complex and interdisciplinary framework, in which some of the most important figures in the history of science (Georgius Agricola, Ulisse Aldrovandi, Luigi Ferdinando Marsili, Antonio Vallisneri, Lazzaro Spallanzani) stand out against the backdrop of the direct or indirect role played in this context by the University of Bologna, which was one of Europe’s leading academic institutions until the 19th century. The first investigations date back to the late 15th century, so Gypsum zones of the Emilia-Romagna were the first evaporitic outcrops studied in the world; analyses and publications have followed one another without interruption until today
La presenza umana nei gessi emiliano-romagnoli. Dal Medioevo a oggi
No full textThe article analyses, in a diachronic perspective, the evolution of the interactions between human communities and Gypsum areas in the Emilia-Romagna Region (Northern Italy) from the Middle Ages to the present. In the Middle Ages, the harsh Gypsum morphologies, suitable for defence, were preferentially home to castles or fortified settlements, while natural cavities were exploited as places of shelter, hermitage or sites for clandestine activities, such as the production of counterfeit coins. With the Modern age, the work of forgers continued to be attested in the caves, while the collection of rainwater in cisterns became systematic and carried on through large structures. In the Contemporary age lies the great transition of the evaporitic areas of Emilia-Romagna from anthropisation, to their centrality during the Second World War (with caves used as shelter for the population and artificial cavities excavated in Gypsum bedrock for military purposes), to depopulation, in some cases total, triggered by the Italian ‘economic miracle’. Depopulation brought to a renaturation of these areas, basis for the institution of present-day parks and reserves
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
LO ZOLFO ROMAGNOLO TRA NATURA E CULTURA
No full textLe plurisecolari vicende estrattive e industriali legate allo zolfo della Romagna sensu GAMBI (1950) e ZANGHERI
(1950), conclusesi nella prima metà degli anni Sessanta del Novecento in seguito alla chiusura degli ultimi
siti attivi, rivestono oggi una notevole importanza culturale, sia sul piano materiale (miniere molto articolate,
strutture di archeologia industriale, villaggi minerari, edifici, infrastrutture, ecc.) che immateriale (studi
scientifici a partire dal XVI secolo, rappresentazioni letterarie e cinematografiche, implicazioni sociali e politiche,
ecc.). L’articolo analizza, in una prospettiva diacronica, tali temi, con uno specifico focus sull’opera
pionieristica, geologica e cartografica, portata avanti dallo scienziato bolognese Luigi Ferdinando Marsili
agli inizi del Settecento. Attualmente, ad oltre cinquant’anni di distanza dalle ultime dismissioni, questo
patrimonio, assolutamente cospicuo, è alla base del senso di identità delle comunità locali, parte integrante
dei quadri ambientali ed è stato in parte recuperato e riconvertito ad usi didattico-museali
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
