    I serramenti in legno nell'involucro edilizio

    No full text
    Tra la fine del secolo XIX e l’inizio di quello scorso, l’impiego di nuovi materiali e di nuove soluzioni costruttive ha dato vita a due filoni di ricerca nell’ambito della cultura progettuale: il primo indirizzato sullo studio del benessere, o meglio del confort ambientale, ed il secondo nella ricerca di un rinnovato concetto di spazio architettonico e di una diversa funzionalità dell’edificio. Il tema della finestre, quale apertura di un involucro murario, assume una importanza basilare in questa nuova progettualità. La tecnologia svolge un ruolo fondamentale perché è capace di ridurre l’involucro edilizio ad un diaframma senza che venga a mancare la qualità fisica dell’abitare. Il passaggio dall’artigianalità all’industrializzazione richiede un nuovo modo di pensare perché il modello ideativo è strettamente legato a quello produttivo. In questo quadro la normativa, in cui confluiscono gli aspetti delle verifiche in fase di ideazione, esecuzione e della regola d’arte rappresenta il segno tangibile dell’esigenza collettiva di un controllo. La questione ruota fondamentalmente intorno a tre definizioni: “esigenze”, “requisito”, “prestazione” tutte sintetizzate nel concetto di qualità intesa come risposta alle esigenze in relazione a ciascun elemento edilizio. In particolare la qualità di un serramento dipende da una serie di requisiti legati a prestazioni come la regolazione energetica, la protezione dagli intrusi, la resistenza agli urti, ecc. finalizzate al benessere o alla sicurezza anche delle relazioni con la tradizione, con il contesto ambientale e culturale e con il gusto. A partire dalla classificazione e terminologia dei serramenti in legno e delle caratteristiche delle essenze lignee maggiormente utilizzate e della lavorazione relativa lo studio si sviluppa attraverso una panoramica approfondita, degli infissi e delle tecnologie di realizzazione dal primo quarantennio del XX secolo agli anni novanta dello stesso. Si studia quindi il ruolo del serramento nel confort degli ambienti abitati con particolare riferimento alle norme vigenti ed alle prove di accettabilità necessarie nella scelta di un infisso. Conclude il lavoro l’esperienza di una metodologia di recupero dell’infisso

    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

    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

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    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

    Protection of third parties in current legislation and preventive practice

    The problem of safety and the management of risks to third parties, which may be caused by a change in the mental or physical health of an employee, is one which affects a number of different areas (infectious diseases, psychiatric illnesses, conditions of drug and alcohol abuse, etc.). Italian legislation deals with the issue of fitness for work through a variety of laws, decrees and regulations which, because many of them were issued in different historical circumstances, are not always mutually harmonized. The growing complexity of the workplace makes the role of the Occupational Physician more complex, and to this person the law assigns the exclusive task of monitoring the health of employees in the cases covered by the current regulations. In our opinion, the Occupational Physician, to the best of his knowledge and conscience, having taken into consideration all the aforementioned factors, must take each case on its merits, in the most responsible manner possible, weighing up the complexity and delicacy of the aspects discussed earlier, and decide to deliver a verdict of fitness and/or to break or not to break the obligation of confidentiality, tending, in our view, to favour the need to safeguard collective health, or that of third parties, should there be a conflict of interest

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
