    A partire da una strategia generale definita a livello di progetto, il risultato principale del progetto GEO.POWER consiste nella definizione di piani d’azione locali per lo sviluppo dell’energia geotermica a bassa temperatura che tenga in considerazione un set di linee guida relative alle migliori tecnologie disponibili e alle migliori applicazioni in edilizia residenziale ed industriale, alle condizioni geologiche ottimali legate alla resa degli acquiferi e dei terreni, all’analisi dei costi e dei benefici per sostenere e incentivare l’utilizzo diretto del calore da fonti geotermiche. In questo progetto risulta fondamentale il coinvolgimento delle Autorità di Gestione dei Programmi Operativi Regionali, ovvero le amministrazioni regionali, le quali condividono ed indirizzano lo sviluppo del progetto al fine di integrare i risultati tecnici di GEO. POWER all’interno del quadro programmatico regionale e di promuovere – attraverso il ruolo di regia che tradizionalmente rivestono - effetti moltiplicatori su tutto il loro territorio

    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

    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

    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

    Centrifuge tests to evaluate performance of the Po river banks during earthquakes

    On the behalf of the Italian Department for the Civil Protection, the Po River Basin Authority carried out a research project to evaluate the seismic hazard of about 90 km of the right bank of the Po river, from Boretto (Reggio Emilia Province) to Ro (Ferrara Province). The project aim is the assessment of 1) the regional seismic risk of the areas under study, 2) the soil properties of the embankment and the foundation ground via site investigation and laboratory tests, 3) the local seismic response of the ground foundation, 4) the liquefaction potential and 5) the stability under static and dynamic conditions of the bank. In order to investigate the seismic response of the embankment, a series of centrifuge dynamic tests on model embankments were performed using a single degree of freedom shaking table installed into the Italian centrifuge at ISMGEO. The models were reconstructed using silty and sandy soils retrieved in situ. Two soil profiles and two geometries were tested. Four time histories were applied to each model; the accelerograms were deduced from a local seismic response analysis carried out referring to one of the investigated site. The tests showed a significant tendency of the banks to amplify the input motions. The amplification is significant in a wide range of frequencies (from about 2.5 to 25 Hz) and increases from the base towards the top. The amplification is influenced by the soil inhomogeneity, especially near the top, also due to wave focalization. No signs of local instability were observed during tests. The experimental results are compared with the preliminary results of a numerical 2D response analyses of the banks

    Dispelling the Myths Behind First-author Citation Counts

    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods
