No full textDuring the last years, the occurrences of degradation processes of underground water are continuously more frequent especially
as concerns the quality of this natural resource. Polluting processes produced by landfills consisting of urban and industrial refuses
are particularly critical for the type of contamination and for the intrinsic difficulty in applying any remedy. In the present research,
we estimate the environmental compatibility of the controlled landfills by applying an integrated method based on (i) the
hydrogeological behaviour of the area surrounding the landfill according to the map of the intrinsic vulnerability of the aquifer(s),
(ii) the setup, the management and the control of the landfill defined by its risk index. The application of this approach to several
landfills located in different geological conditions allowed us to evaluate the efficiency of the control system of the existing
landfills and the priority list of the intervention to be performed to improve the future management and to protect the surrounding
environment

No full textThe preliminary results aimed to defining the environmental conditions of the hydrographic basin and based on geochemical and hydrological methods are presented. The discussed case study is represented by the Reno river, northern Italy, where its environmental conditions are initially determined with a geochemical analysis of the solid suspended material and of the water in 8 monitoring stations. Additionally, a geochemical monitoring has been carried out for two of the major hydrographic sub-basins: a) Lavino river, with areal extension of 82,6 km2 and mean annual discharge of 0.62 m3/s (period 1998-2004) and b) Savena river, with areal extension of 168,9 km2 and mean annual discharge of 2.8 m3/s (period 2000-2004).
In particolar, the chemical analysis of the collected solid material by means of an X-rays method and of the waters by means of ICP-MS standard procedures allowed to define i) the principal mean concentrations of both water and sediments and their comparison with the Italian and European legislative limits; ii) the variations in ionic concentration of both sediments and water, therefore enabling to infer the degree of erodibility of the rocks outcropping within the hydrographic basins, their relation with the amount of precipitation and corrivation times of the water at the monitoring sections
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
