Coastline Mapping Using QuickBird Satellite Imagery
No full textIn this work we have been investigated the potential of the new Earthwatch QuickBird high resolution satellite (launched on October 2001) for deriving coastlines and analyzing coastal changes. A coastline mapping project has been carried out on "Sacca di Goro" lagoon (Ferrara province - Emilia Romagna region - Italy): a very interesting lagoon limited from the sea by a system of sand-banks. The Province of Ferrara has been acquired a new Quickbird image (panchromatic and multispectral, February 2003) of the “Sacca di Goro”, and this image has been geometrically corrected with different non parametric models (polynomial and rational function models) within PCI OrthoEngine 8.2 software.
Using corrected satellite imagery we have been obtained the shoreline (by manually interpretation)

No full textNel presente lavoro viene descritta la Stazione Mareografica Integrata di Porto Garibaldi (FE), recentemente realizzata dalla Provincia di Ferrara (2009) e pienamente operativa dall’inizio del 2010. Vengono descritte sommariamente le caratteristiche della Stazione e dei sensori installati. Viene inoltre illustrata la procedura individuata per l’elaborazione dei dati mareografici con l’applicazione di opportuni filtri per l’analisi di qualità del dato e l’estrazione dei livelli medio mare orario, giornaliero, mensile ed annuale
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
