Il ruolo urbano delle biblioteche
No full textLe biblioteche, nel corso della storia, grazie alla loro capacità di costituirsi come centralità hanno modellato lo spazio socio-culturale della città ed influenzato molte dinamiche urbane. È accaduto in passato, basti pensare (tra le tante) alle vicende che hanno coinvolto il Cassaro (intrinsecamente legato alla presenza del Collegio Massimo dei Gesuiti, poi Biblioteca Nazionale e infine Regionale) e, in modo diverso, a certi fenomeni in atto oggi in alcuni quartieri della città con le diverse sezioni territoriali della Biblioteca Comunale.
Esiste, dunque, un rapporto di omologia tra la struttura urbana e le biblioteche che, se ripensate, possono farsi motrici della rigenerazione urbana e delle nuove dinamiche di sviluppo culturale di Palermo.Over history, thanks to their ability to constitute themselves as centralities, libraries have modelled the socio-cultural space of the town and influenced many urban dynamics. This has happened in the past, among many others it is enough to think about the events which have involved the Cassaro (intrinsically linked to the presence of the Collegio Massimo dei Gesuiti, then Biblioteca Nazionale and lastly Biblioteca Regionale) and, in a different way, about certain phenomena underway today in some areas of the town with different territorial sections of the Biblioteca Comunale. Thus, there exists a homology relationship between the urban structure and the libraries which, if rethought, can become agents of urban regeneration and of new cultural development dynamics of Palermo
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
Althusser e gli apparati ideologici di Stato. Ideologia ed egemonia: un confronto con Gramsci
No full textL'articolo analizza gli apparati ideologici di Stato di L. Althusser leggendoli come più o meno indiretta filiazione delle strutture di produzione di consenso e di egemonia tipiche di Antonio Gramsci. Vengono, su questa falsariga, analizzati i diversi significati del temine ideologia in Gramsci e Althusser
Clinical manifestations of cuticular drusen. Current perspectives
Full text linkCuticular drusen are part of the spectrum of age-related macular degeneration (AMD) with particular clinical and multimodal imaging characteristics. This drusen sub-population shares several high-risk single nucleotide polymorphisms with AMD. Despite this feature, they can manifest at a relatively young age, presenting with a female preponderance. Multimodal imaging is essential for characterizing such lesions, using a combination of color fundus photographs, optical coherence tomography (OCT), fluorescein angiography (FA), and fundus autofluorescence (FAF). The classic starry-sky pattern visible on FA and the typical central hypoautofluorescent lesion with hyperautofluorescent rim on FAF is consid-ered the result of a central retinal pigment epithelium (RPE) erosion from these triangular elevations of the RPE-basal lamina. This finding may also be responsible for the typical choroidal hypertransmission appreciated through OCT. The clinical course of cuticular drusen may be relatively benign at early stages, with small drusen presenting at a young age. However, the presence of clinical phenotypes characterized by diffuse involvement and/ or accompanying large drusen in patients older than 60 years may confer a significant risk for either macular neovascularization or geographic atrophy
