Modifiche idrochimiche e di portata sorgentizia indotte da sovrasfruttamento: il caso delle sorgenti di Cancello (Campania)
No full textLa falda di base della dorsale carbonatica di Cancello alimentava due grosse scaturigini (Mofito e Calabricito) caratterizzate da un chimismo sensibilmente diverso rispetto a quello tipico di tali acquiferi. La Valle Caudina separa detta dorsale dai Monti di Durazzano, a nord, anch'essi carbonatici e ritenuti idrogeologica-mente non collegati ai rilievi meridionali. Tra l'altro, la falda di base di Durazzano (intercettata dai due campi pozzi di P/te Tavano) evidenzia un chimismo assai diverso rispetto a Cancello. Un altro campo pozzi è stato poi realizzato nella dorsale di Cancello. Col tempo le sorgenti si sono esaurite ed i dati raccolti fanno ritenere che tale evento sia legato anche agli attingimen-ti dai pozzi di Ponte Tavano: tra l'altro il chimismo di queste acque ha via via assunto connotazioni prossime a quello che caratterizzava le sorgenti Mofito e Calabricito
Aquifer pollution vulnerability in the Sorrento peninsula, southern Italy, evaluated by SINTACS method
No full textA groundwater contamination vulnerability map of the aquifers of the Sorrentine peninsula, Italy, has been produced using a Geographical Information System (GIS). The parametric method SINTACS has been applied in this prevalently karstic area. This method allows a detailed definition of vulnerability, providing a specific set of weights for karstic, fissured and porous hydrogeological environments. The final map shows the influence of the morphological and lithological setting on the contamination vulnerability assessment
Overview of the hydrogeology of the “Conca di Acerno” (SA)
No full textThe study of available and acquired data yielded the follow
ing main results about groundwater flow system in the Acerno basin (Conca di Acerno), sometimes in disagreement with pre-vious studies:
• two different groundwater flows have been identified: the first one in the carbonate bedrock (feeding the Ausino, Ausinetto and Avella spring group) and the other one in the river and lake sediments of the basin (feeding the Olevano spring and the lea-kages through the Tusciano riverbed;
• a significant flow increase in the Tusciano river has been identified coming from the right bank of the river Tusciano;
• analyses of chemical, isotopic and piezometric data showed that occurs an interaction between the two aquifers, and between these and the hydrographic network;
• the limits of the groundwater basin feeding the Acerno spring group have been established more accurately, especially on the basis of the carried out hydrogeological balance. In fact, the area of the groundwater basin has been reduced and, to the east, brought to correspond with the position of an important tec-tonic lineament, located south of the Mt. Raia della Licina;
• level with the river Tusciano, major tectonic lineaments act as a groundwater flow barrier toward south

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
