«El si butta per zerto un bel poltron»: Luigi Pulci a Milano
No full textDopo aver ricostruito, per quanto le fonti consentano di fare, i vari soggiorni di Luigi Pulci a Milano e le sue relazioni con l'ambiente milanese, che ebbero significativi riverberi sulla sua opera letteraria, il saggio si concentra su altri personaggi, strettamente collegati all'autore del Morgante, che in quegli stessi anni frequentavano assiduamente la corte sforzesca. Anche le testimonianze di Piero Vespucci, Benedetto Dei e Giovanni Ridolfi, infatti, contribuiscono a delineare un ritratto della città di Milano e della sua corte come poteva apparire agli occhi dei visitatori fiorentini dell'epoca
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
An update on several indicators of the quality of data flow in a cancer registry in Vercelli (Piedmont, Italy)
No full textThe first estimates of cancer incidence in the city of Vercelli in Piedmont (Italy) are now available for the years 2002 to 2005 and preliminary data are also available up to 2009. With respect to previously published results, the cancer database has been integrated with information from additional data sources to ensure that it will become, in the near future, a sound basis of information upon which to build an accredited cancer registry. An evaluation was therefore performed of two indicators of the quality of data flow: the proportion of cases with histological confirmation of diagnosis and cancer mortality to incidence (M/I) ratios. Both show an improvement with respect to 2005 but need to be significantly improved to reach the levels of excellence and accuracy that a registry must necessarily possess. Local health authorities will need to ensure staff availability and facilitate access to key data sources to fully evaluate cancer epidemiology in the area

No full textEpidemiology of tumour mortality from 2000 to 2005 in the province of Vercelli (Italy).
No full textThe main aim of this study was to assess the burden of cancer disease in residents of Vercelli (northern Italy), by analysing mortality data and hospital discharge forms. This was done in order to verify whether, as widely suspected among the city's population, an increased risk of cancer exists in the area, due to the large number of existing agricultural and industrial activities. Tumour mortality rates were compared with mortality data from the tumour registries of the province of Biella and of the city of Turin to identify a possible excess number of cases in Vercelli.An increased mortality rate was observed with respect to reference values (mortality registry of the city of Turin) for several tumours; more specifically results revealed a significantly increased mortality rate due to colorectal tumours, leukemias and nervous system tumours in both genders. Excess mortality was detected in males but not in females for esophageal cancer, non melanoma skin cancers, pancreatic, laryngeal, prostatic, renal and bone cancers. Conversely, in females, the standard mortality ratios (SMR) were found to be statistically significant for renal and laryngeal cancers and for Hodgkin's lymphom
