    Using exergy to analyze the sustainability of an urban area

    No full text
    The extended exergy analysis method, taking into account the mean life time cycle of building, has been applied to evaluate the sustainability of an urban area. The impact of the emissions due to the life cycle of the buildings has been evaluated. Two thermodynamic indexes, gI and gII showing, respectively, the first and second law efficiency of buildings, have been proposed as thermodynamic indexes. The applied methodology provides a single thermodynamics environmental criterion for the selection of technological alternatives, strategies and designs that produce lower environmental impacts connected to higher exergy indexes gII

    This research provides an integrated methodological approach based on the combined use of spatial syntax modelling and eyetracker analysis techniques for lighting sustainability aimed to adaptive reuse of all the spaces with high historical, architectural, philological value of Cultural Heritage (CH). MosLESS (Modelling Sustainable Lighting with Eyetracker and Spatial Syntax techniques) is the proposed method, that can suggest fundamental guidelines for dynamic and static lighting in the museographic and museological areas, but also for reuse, conservation and enhancement of historical and CH buildings integrated with efficient energy management and conservation and protection needs. The National Museum of San Matteo in Pisa (Italy) was the pilot project. Particular environments were chosen for the experimental measurement campaigns carried out to assess dynamic and static visual fields, vision and perception. Methodological approach and results can be useful tools for exhibition planning with important energy, social and cultural effects. A further objective of the research will be to facilitate cultural exchanges, communication and new procedures for the digital management of the transmission or modification of museographic and exhibition projects, up to relations with public clients, as well as integrated management of information and decision-making processes

    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

    La pianificazione energetica e i processi di Decision Making debbono inglobare le conoscenze scientifico ambientali per garantire uno sviluppo economico garantendo il rispetto dell'ambiente. Nel lavoro vengono presentate velocemente le principali metodologie di analisi termodinamiche usate nella modellistica ambientale insieme ad alcuni esempi di ricerca scientifica appositamente sviluppati per i decisori politic

    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

    Get PDF
    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

    Dispelling the Myths Behind First-author Citation Counts

    Get PDF
    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
