    L’obiettivo della presente ricerca consiste nell’indagare le relazioni che intercorrono tra la tecnologia di manifattura additiva, alla scala dell’edificio, e la forma architettonica espressa dal sistema produttivo oltre ai materiali coinvolti nel processo e la funzione assunta dal manufatto. Il lavoro nella prima parte tratta dettagliatamente l’evoluzione delle tecniche utilizzate per le costruzioni in terra cruda. Questo excursus storico mira a validare il metodo additivo del Material Extrusion come nuova frontiera tecnica nel progetto e nella costruzione dell’architettura in terra cruda attraverso l’analisi di opere realizzate. La tesi prosegue prendendo in considerazione le metodologie progettuali e processuali necessarie per questa categoria di progetti affrontando criticamante il ruolo dell’architetto nell’era della progettazione computazionale e dei processi produttivi automatizzati nel settore edile. I risultati della ricerca si sostanziano in un modello che raccoglie alcuni criteri compositivi per consentire di operare nella progettazioe di shelter urbani prodotti attraverso tecnologia additiva con l’uso di materiali naturali in contesti di spazio pubblico in area mediterranea. Infine, in linea allo sviluppo di analoghe ricerche scientifiche internazionali, è stato realizzato un dimostratore architettonico a scala reale, avvalendosi delle attrezzature che il Politecnico di Bari offre nei suoi laboratori. In questo contesto, il processo di definizione formale, le tecnologie di realizzazione e i materiali impiegati collaborano sinergicamente per migliorare le condizioni termo-igrometriche dell’ambiente contribuendo, allo stesso tempo, al benessere di chi ne fruisce.The aim of the following research is to investigate the relationships between the Additive Manufacturing technology, at the scale of the building and: the architectural shape expressed by the production system; the materials involved in the process; the function taken by the product. In the first part, the research gives a detailed analysis of the evolution in the techniques used for constructions made of raw earth. The historical excursus aims to validate the additive method of Material Extrusion as a new technical frontier in the design and construction made of raw earth architecture through the analysis of existing projects. The thesis then moves on considering the design and process methodologies required for similar projects, analysing the role of the architect in the era of computational design and automated production processes in the construction industry. The results of the research lead to a model that brings together a set of compositional criteria for the design of urban shelters produced through additive technology and the use of natural materials in contexts such as the public space of Mediterranean cities. Lastly, in line with similar internWational scientific research, a full-scale architectural demonstrator was realised, using the equipment that the Polytechnic of Bari provides in its laboratories. In this context, the form-finding process, the construction technologies and the materials used, work together synergistically to improve the thermo-hygrometric conditions of the environment while contributing to the well-being of those who use it

    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

    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

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    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

    Author Under Sail The Imagination of Jack London, 1893-1902

    No full text
    In Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
