Risk stratification in prostate cancer treated with radiation therapy: A window of opportunity for new clinical trials
No full textGli studi sulla poesia del Quattrocento
No full textAll’interno di un volume interamente dedicato alle opere di Marco Santagata, il contributo si focalizza sugli studi relativi alla poesia del Quattrocento, perseguiti a partire dall’inizio dell’attività di studioso e proseguiti lungo tutto l’arco della vita. Viene perciò analizzato il volume sulla "Lirica aragonese", sottolineandone le novità, relative in particolare ai caratteri del primo petrarchismo aragonese; segue l’approfondimento sugli studi della lirica feltresco-romagnola, doviziosi di spunti e riflessioni, anche teorici, sul nascere del petrarchismo cortigiano quattrocentesco; infine vengono ricordate le ricerche sulla poesia pastorale modenese, legate all’esame dei "Pastoralia" di Boiardo, studiati nel loro insieme ma anche analizzati in dettaglio, con arricchimenti sostanziali.Within a volume entirely dedicated to the works of Marco Santagata, the contribution focuses on studies related to fifteenth-century poetry, pursued from the beginning of his scholarly activity and continued throughout his life. The volume on “Aragonese Lyric” is therefore analyzed, emphasizing its novelties, relating in particular to the characteristics of early Aragonese Petrarchism; this is followed by an in-depth study of the studies of “Montefeltro lyric”, full of ideas and reflections, including theoretical ones, on the birth of fifteenth-century courtly Petrarchism; finally, the research on Modenese pastoral poetry is recalled, linked to the examination of the “Pastoralia” of Boiardo, studied as a whole but also analyzed in detail, with substantial enrichments
«Il salto degli Orlandi» (e quello dei Marchi)
No full textIl saggio analizza una delle prime prove del Marco Santagata narratore: il racconto intitolato "Il salto degli Orlandi", il quale ha avuto due edizioni corrispondenti a due diverse redazioni (la prima in rivista, su «Paragone. Letteratura», s. III, XLIX, 17-18, 1998, pp. 36-65; la seconda in un volume a sé, Palermo, Sellerio 2007, pp. 115-66, che porta lo stesso titolo e raccoglie tre racconti precedentemente editi). Confrontando sobriamente le due versioni del testo, se ne analizza l’intreccio di natura fortemente metaletteraria (il racconto è fondato sulle ipotetiche peripezie extra-testuali dei due Orlandi: quello di Boiardo e quello di Ariosto), mostrando come esso ci aiuti a comprendere la complementarità tra i due versanti dell’attività letteraria di Marco Santagata (1947-2020), lo studioso e il narratore

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
Inter-patient image registration algorithms to disentangle regional dose bioeffects
No full textRadiation therapy (RT) technological advances call for a comprehensive reconsideration of the definition of dose features leading to radiation induced morbidity (RIM). In this context, the voxel-based approach (VBA) to dose distribution analysis in RT offers a radically new philosophy to evaluate local dose response patterns, as an alternative to dose-volume-histograms for identifying dose sensitive regions of normal tissue. The VBA relies on mapping patient dose distributions into a single reference case anatomy which serves as anchor for local dosimetric evaluations. The inter-patient elastic image registrations (EIRs) of the planning CTs provide the deformation fields necessary for the actual warp of dose distributions. In this study we assessed the impact of EIR on the VBA results in thoracic patients by identifying two state-of-the-art EIR algorithms (Demons and B-Spline). Our analysis demonstrated that both the EIR algorithms may be successfully used to highlight subregions with dose differences associated with RIM that substantially overlap. Furthermore, the inclusion for the first time of covariates within a dosimetric statistical model that faces the multiple comparison problem expands the potential of VBA, thus paving the way to a reliable voxel-based analysis of RIM in datasets with strong correlation of the outcome with non-dosimetric variables
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
