    APPROFONDIMENTO SUI FATTORI DI RISCHIO PER LA POLMONITE DA LEGIONELLA SPP: REVISIONE DEI CASI NOTIFICATI IN REGIONE EMILIA-ROMAGNA

    No full text
    OBIETTIVI: La polmonite da Legionella spp è associata alla presenza di diversi fattori di rischio, in particolare malattie cronico degenerative, fumo di sigaretta, assunzione di alcool e droghe, e in generale con fenomeni di immunodepressione. I dati ufficiali delle notifiche riportano tuttavia una percentuale di circa il 50% di persone che ammalano in assenza di co-morbilità. Scopo dello studio è revisionare le schede di sorveglianza per la legionellosi per verificare se la mancata segnalazione di fattori di rischio sia un fenomeno reale o legato a carenze nella compilazione della scheda e/o a errata diagnosi. METO DI: Lo studio, condotto con metodologia casocontrollo, prevede di revisionare le schede di sorveglianza per la legionellosi pervenute alla Regione Emilia Romagna nel triennio 2009-2011. La prima fase riguarda una attenta rilettura delle schede per estrapolare quelle in cui non vengono segnalati fattori di rischio noti in grado di spiegare la malattia (“casi”). Successivamente ad ogni caso viene associato un paziente con polmonite da Legionella portatore di fattori di rischio noti estratto casualmente dall’intera lista (“controllo”). RISULTATI: Lo studio è in corso e si concluderà nel mese di settembre. Da una prima indagine è emerso che oltre il 20% delle schede raccolte negli anni presi in considerazione riguardano soggetti apparentemente privi di fattori associabili all’insorgenza della malattia. Il medico di famiglia ed i sanitari che hanno avuto in cura il paziente nel periodo della polmonite vengono contattati per completare la scheda. Particolare attenzione viene data alle indagini laboratoristiche svolte per stabilire l’origine della polmonite (antigene urinario, metodo colturale, sierologia ecc.) oltre all’indagine anamnestica successiva alla polmonite per comprendere se siano comparsi sintomi di malattie cronico-degenerative non riscontrabili al momento dell’evento. CONCLUSIONI: I risultati di questa indagine possono rivestire particolare interesse per la mancanza di informazioni scientifiche sulle caratteristiche dei soggetti malati di legionellosi, ma apparentemente privi di fattori di rischio associati ad infezioni da opportunisti. In particolare, lo studio intende distinguere se al momento dell’esordio non fossero presenti malattie immunodepressive comparse solo dopo l’evento oppure se sia opportuno consigliare maggiore attenzione nella compilazione delle schede e nella attribuzione al germe legionella della polmonite in relazione al tipo di indagine laboratoristica utilizzata

    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

    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.
