    Monitoring Northern Adriatic Seashore At Jesolo Resort

    Full text link
    Jesolo is the main seaside resort on the northern Adriatic seashore, and among the most important along the whole Italian coast, attracting millions of international tourists every year. It is located in northwest Italy, close by the Venice lagoon. During late fall and winter, it is exposed to intense wind storms that cause severe sediment mobilization and, in some cases, beach reshaping events. Considering its economic relevance and the multiple activities taking place on the sea (tourism, fishery, diving, etc.), Jesolo beach is an ideal candidate for implementing research activities aimin to investigate marine and coastal dynamics. The development of innovative modeling and monitoring approaches will lead to more efficient coastal planning and management, in the wake of the increasing awareness about coastal vulnerability issues, including climate change-related phenomena. In the framework of the Italian Flagship Project RITMARE—the Italian Research for the Sea, Subproject 3 (Coastal Waters), Workpackage 4 (Coastal Oceanographic Modeling), the Jesolo littoral zone has been identified as the Strategic Test Area for the study of coastal dynamics and for the collection of a time series of integrated measurements to support comprehensive, detailed insight on coastal circulation, wave dynamics, sediment transport and coastal erosion. The research plan, launched in spring 2013, envisaged the deployment of an acoustic system for the continuous measurement of vertical 3D current profiles and wave spectral parameters approaching the coast. A video monitoring system was installed for a high-frequency survey of the key morphological metrics along the coastal reach. Thisis flanked by a morphobathymetric survey plan allowing a high-detail description of morphological variations, a thorough estimate of sediment fluxes and the validatio of the video monitoring system. The research area covers approximately 1.5 square kilometers, ranging nearly 1 kilometer in the long-shore direction and 1.5 kilometers in the cross-shore direction, reaching an offshore depth of 10 meters and enclosing the whole active beach. The data collected will be used for calibrating of a standard alkaline battery in these conditions is approximately 100 days, but the bottleneck for system maintenance is caused by severe biofouling occurring in the shallow working environment, requiring at least monthly upkeep inspections

    The use of integrated wave-current-sediment numerical tools to model coastal dynamics: an applications in the North Adriatic Sea

    The paper presents a preliminary implementation of a 3-D integrated, wave-current-sediment numerical model in a shallow water area of the NW Adriatic Sea, with the aim of assessing the erosion patterns and bottom morphology modifications that may be induced by severe marine conditions. The numerical modeling results show how complex, integrated numerical tools are becoming suitable both for preliminary investigations and for effective littoral management activities as well

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    Hybris. I limiti dell'uomo tra acque, cieli e terre

    No full text
    La parola hybris significa violenza, oltraggio, arroganza: è una parola degli uomini e indica la violazione di un limite, di una misura, di fronte agli dei, agli altri uomini, di fronte alla natura. È la violazione di un kosmos e di una armonia, una assenza di consapevolezza e di responsabilità. È avanzare in equilibrio su un filo fragile con la superbia e la sventatezza che lo possono spezzare. Hybris, allora, tra gli entusiasmi della tecnologia e le inquietudini ecologiche diviene una parola adatta per il nostro presente, ne avvertiamo sempre più le conseguenze in ogni nostra azione, sempre più forte il pericolo per la nostra stessa esistenza. È forse buona cosa pensarci. Ne discutiamo in questo libro unendo in maniera inconsueta le parole dei classici antichi e i pensieri della scienza moderna, per cercare di comprendere, a partire dall'idea di Prometeo che ha donato agli uomini il fuoco, le lettere e i numeri, se v'è ancora qualche equilibrio possibile tra la nostra hybris e il mondo che ci circonda

    Variations on the Author

    “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

    Appropriate Similarity Measures for Author Cocitation Analysis

    Full text link
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
