No full textL’isola di Sacca San Biagio a Venezia, deposito di ceneri del vecchio inceneritore della città, può diventare un’isola-laboratorio per lo studio di tecnologie verdi finalizzate al risanamento di siti inquinati. In questo lavoro sono riportati i risultati di una ricerca sullo stato della vegetazione spontanea dell’isola e sulla presenza di microrganismi benefici, i funghi micorrizici arbuscolari (MA), fondamentali per il biorisanamento dell’ambiente. Lo studio ha permesso la valutazione del processo in atto di colonizzazione spontanea dell’isola da parte della vegetazione e dei funghi MA ad essa associati. L’effetto positivo di tali funghi simbionti è stato messo in evidenza dalla presenza nel suolo dell’isola di significative quantità di glomalinrelated soil protein (GRSP), una proteina fungina di grande efficacia nel processo di trasformazione delle ceneri dell’isola in suolo fertile. L’identificazione delle specie fungine e la loro presenza nella comunità vegetale dell’isola di Sacca San Biagio rappresenta, inoltre, il primo passo verso l’acquisizione di ceppi fungini resistenti ai metalli pesanti, da utilizzare nei programmi
di rivegetazione o biorimedio di siti inquinati o fortemente disturbati

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
