EXPERIMENTAL DATA ANALYSIS AND COMPARISON WITH THE NUMERICAL RESULT FOR THE SINGLE DEVICE TESTS
No full textIn the frame of the SPIDER (Strands Pre-stressing far Internal Damping of Earthquake Response) Project a new system far the protection of buildings against the earthquake is studied. The project studies the application of pre-stressed cables in series with tension spring dampers: damper-cable system (DCS). The cable is fixed at one of the ends to the basement of the building and, at the other end, to the upper part of the building. The shock absorber, coupled in series with the cable, is located close to the basement far easy installation and maintenance. The cable is connected with a special device at each of the floor. This device allows the cable to slip inside and move with respect to the structure. In this report the experimental results obtained during the test carried out at Enel.Hydro on the single DCS in the straight and deviated configuration ara analysed and compared with the results obtained with numerical analyses performed with ABAQUS code. The results are compared with the ones obtained with the model proposed by the system manufacturers and with a modified model, developed analysing the tests results, that batter reproduces the DCS behaviour.

A Life Cycle Assessment Pilot Study in an Italian Dairy Company
No full textA research project to apply LCA methodology to an Italian dairy firm was recently carried out. The main project objective was to develop a simplified methodology for introducing environmental concerns based on a life cycle approach in industry decision-making. The company was selected on the basis of the economic importance of the agro-industrial branch in Emilia-Romagna region and its technological representativeness. The entire activity is carried out under the technical and scientific supervision of ENEA (Italian National Agency for New Technology, Energy and the Environment), ERVET S.p.A. (Regional Agency for Industrial Policies), the Department of Business Administration and the Department of Applied Chemistry and Material Science of Bologna University.In this paper the methodological approach and the preliminary results of the study are discussed
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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
