No full textThe TRIX index method was applied to historical data set of Senigallia Transect (Northern Adriatic Sea) to evaluate the eutrophication level in 3 stations characterised by different trophic conditions. Dissolved Inorganic Nitrogen (DIN) and Dissolved Inorganic Phosphorus (DIP) were used and TRIX index showed a significant positive correlation with DIN. In 1994 the trophic front expanded up to 15 nM, in an area usually external to trophic coastal front, and we correlate this phenomenon with meteo-climatic conditions of the period. The TRIX index was confirmed to be a valid method in the monitoring of the trophic level in coastal waters.E\u27 stato applicato l\u27indice TRIX per la valutazione del livello di eutrofizzazione sulla serie storica proveniente dal transetto di Senigallia (Adriatico settentrionale), su 3 stazioni caratterizzate da un differente grado di trofia. I parametri utilizzati per il calcolo dell\u27indice sono: azoto inorganico disciolto (DIN) e fosforo inorganico disciolto (DIP) come PO4. L\u27indice TRIX ? correlato significativamente, in modo positivo, soltanto con il DIN. Nel 1994 si ? manifestata la tendenza ad una espansione del fronte della zona trofica verso il largo fino a 15 nM, dove solitamente non si riscontravano fenomeni di eutrofia. L\u27indice si ? rivelato un valido strumento per il monitoraggio del livello trofico dell\u27Adriatico ed il fenomeno individuato dal TRIX nel 1994 trova un riscontro anche negli eventi meteo-climatici registrati in quel periodo

UPPER OCEAN THERMAL STRUCTURE AND FRONTS BETWEEN NEW ZEALAND AND THE ROSS SEA (AUSTRAL SUMMER 1994-1995 AND 1995-1996)
No full textThis paper describes the upper ocean thermal structure between New Zealand and the Ross Sea, and its evolution from the austral spring to summer 1994-95 on the basis of four high resolution XBT sections, and during the summer 1995-96 with two high resolution XBT sections. The area of investigation is almost completely (with the exception of the southernmost part) interested by the Antarctic Circumpolar Current (ACC). The main fronts (SubAntarctic Front, Polar Front and southern front) included in the ACC are individuated, and a new front, supposed to derive from a splitting of the SAF in a Northern SAF (NSAF) and a Southern SAF (SSAF), is identified. The NSAF is always located at the end of the Campbell Plateau, on the continental slope, and the SSAF is located around 58 °S, with the exception of the December 1994-January 1995 cruises. Going from spring to the end of the austral summer, the PF appears to retreat from north to south, while the southern front shows a stable position on the northern flanks of the Pacific-Antarctic and Southeast Indian Ridges. The thermal structure of the six sections reveals the presence of intense mesoscale dynamics, with cold nuclea of Antarctic Surface Water (AASW) detached from the PF and noticed up to 1000 km north of it
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
Seasonal evolution of the physical water properties observed from the Senigallia transect
No full textVariations 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
