L’esperienza più forte della mia vita”.Costantino Nivola, l’esilio e il mito della comunità
No full textCaso rarissimo di artista italiano che ha scelto di lasciare l'Italia in quanto antifascista, Nivola trova se stesso lungo le tappe di una migrazione che va oltre il trasferimento a New York, e ognuna delle quali implica l'acquisizione di un diverso linguaggio. Nelle prime fasi dell'esilio le parlate si sovrappongono e si confondono, così come i ruoli sociali. Al termine di questo itinerario e nel corso di circa un decennio, dalla crisalide di un operatore dal profilo professionale incerto, oscillante tra le posizioni di grafico editoriale, illustratore, pubblicitario, decoratore e aspirante pittore, sarebbe nata l'immagine del Nivola scultore, attentamente costruita negli anni cinquanta
Cardiac involvement in the adult primary vasculitides
No full textIntroduction: Heart involvement in vasculitis is rare, but potentially severe. The ascertainment of cardiac disease in vasculitis is complex and requires an integrated multidisciplinary approach involving the Rheumatologist, Radiologist, Cardiologist, and Heart surgeon. Areas covered: the authors searched PubMed using the keywords ‘heart’[Mesh] and vasculitis”[Mesh]. Expert opinion: Virtually any vasculitis can affect the heart, but cardiac involvement is more common in some vasculitides such as Takayasu arteritis, polyarteritis nodosa, and eosinophilic granulomatosis with polyangiitis. Immunosuppressive treatment and when indicated surgery can improve the prognosis
Biotherapies in large vessel vasculitis
No full textThe mainstay of therapy of large vessel vasculitides (LVV) remains glucocorticoids (GC). Although most patients initially achieve disease remission, relapses and GC dependence are seen in more than two-thirds of cases. Conventional synthetic disease-modifying antirheumatic drugs (DMARDs) showed little or no steroid sparing effects, while biological agents represent a valid therapeutic option in patients with severe and/or relapsing LVV
Epidemiology of Behçet Syndrome
No full textBehçet disease (BD) is a systemic inflammatory disease typically characterized by oral and genital ulcers and variable manifestations affecting other organs, mainly skin and eye. Published epidemiologic studies on BD are difficult to compare because of different study designs, settings, methods and the lack of universally accepted classification criteria: 16 different sets of classification/diagnosis criteria have been published so far; in the beginning of the chapter we compare different criteria subsets with estimates of sensitivity and specificity. After that, we review epidemiologic clinical studies (registries, hospital records, district databases): consistent data point to higher incidence and prevalence rates of BD along the ancient Silk Road (stretching from the Middle Est to the Far East and Mediterranean Countries) compared to a lower prevalence in Northern European Countries and United States genetic and environmental factors have been evaluated as well as age of onset, male-to-female ratio and systems involvement
Urban alternative cultural production in Turin: An ecological community approach
No full textFrom the ashes of the creative city paradigm, there is a growing awareness of the urban creative economy as an adaptive complex system of intertwined actors and institutions. Yet, especially in the European context, little attention has been given to understanding informal and alternative art spaces and venues that contribute to the vibrancy of the urban cultural scene. Drawing on the emerging creative and cultural ecology literature, the article proposes a conceptual and empirical framework to analyze alternative cultural production as an ecological community. After providing a conceptualization of distinct types of alternative cultural organizations, we investigate the economic, spatial, and relational structure of more than 50 art spaces in Turin, Italy, an industrial city that has experienced a radical urban transformation based on culture-led development strategies. Using both a quantitative and qualitative approach, our findings unveil a distinction between centers pursuing artistic specialization and those more oriented toward aggregating diversified cultural activities. The two types of organizations coexist within the community, but the difference in their mission and operation influences the organizational structure, the involvement in neighborhood revitalization, and features of the local network of collaborations. From a spatial perspective, while the centers tend to cluster in the main peripheral areas of social and urban transformation, the analysis points out possible different locational choices and spatial dynamics for the two types of organizations in distinct areas of commercial and real-estate-led transformation
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
