Abdominal Subcutaneous and Visceral Adipose Thickness Are Independently Associated with Insulin Resistance
No full textAbdominal Subcutaneous and Visceral Adipose Thickness Are Independently Associated with Insulin ResistanceView session detail Author Block: SIMONA BERTOLI, ALESSANDRO LEONE, ANGELA SPADAFRANCA, RAMONA DE AMICIS, LAILA VIGNATI, GIORGIO BEDOGNI, ALBERTO BATTEZZATI, Milan, Italy Regional fat distribution rather than overall obesity has been recognized as the link between obesity and diabetes. The measurement of abdominal subcutaneous and visceral adipose thickness (SAT and VAT) by ultrasonography (US) is simple, inexpensive and non-invasive. We have recently shown that both VAT and SAT are associated with metabolic syndrome and its components but their association with insulin resistance (IR) remains unclear. To investigate such association, we carried out a cross-sectional analysis of 4108 Caucasian adults followed as outpatients at the International Center for the Assessment of Nutritional Status (ICANS) in Milan. They were aged 18-87 years, were mostly females (71%) and had a median body mass index (BMI) of 28.7 (25.4 to 32.7). VAT and SAT were assessed by US using a validated protocol. HOMA-IR was used as surrogate index of IR. HOMA-IR was used as surrogate index of IR. 25,1% of the sample was detected to have IR (HOMA-IR > 3,6). The associations of VAT and SAT with IR was examined using multivariable linear regression with fractional polynomials. LogeHOMA was independently associated with VAT (cm), SAT0.5 (cm) and age-2 (years) but not with sex (R2 = 0.452, RMSE = 0.49) (Figure). We conclude that US-VAT and SAT are independently associated with IR in a large sample at different level of BMI

A new bibliometric index based on the shape of the citation distribution.
No full textIn order to improve the h-index in terms of its accuracy and sensitivity to the form of the citation distribution, we propose the new bibliometric index [symbol in text]. The basic idea is to define, for any author with a given number of citations, an "ideal" citation distribution which represents a benchmark in terms of number of papers and number of citations per publication, and to obtain an index which increases its value when the real citation distribution approaches its ideal form. The method is very general because the ideal distribution can be defined differently according to the main objective of the index. In this paper we propose to define it by a "squared-form" distribution: this is consistent with many popular bibliometric indices, which reach their maximum value when the distribution is basically a "square". This approach generally rewards the more regular and reliable researchers, and it seems to be especially suitable for dealing with common situations such as applications for academic positions. To show the advantages of the [symbol in text]-index some mathematical properties are proved and an application to real data is proposed
A geometric model for the analysis of citation distributions
No full textIn this paper, we present an empirical study for modeling the citation distribution of papers of individual authors. We analyzed the citation records of applicants to the so called “Abilitazione Scientifica Nazionale” (ASN), a new procedure, based on scientific qualification criteria, for the recruitment of academic staff in Italy. We analyzed citation records of 131 physicists who were applicants in the ASN for a full professorship in the specific area of Condensed Matter Physics, using different mathematical models, namely: zeta, geometric, logarithmic and Pareto (of the first kind). Each model was “estimated”, on the basis of the observed citation pattern, via minimum Kullback-Leibler distance method. The geometric distribution was also considered by using a trimmed version of the estimator. As a measure of the effectiveness of the model, we computed the Kolmogorov-Smirnov distance. The most remarkable result is that the geometric distribution can provide an adequate tool for the modelization of the citation distribution of an author. Model fit may be further improved by adopting the trimming method

Painting in Vernacular. Languages at the Crossroads in Sixteenth-Century Venice
No full textIdentifying the questione della lingua as a moment of rupture for the cultural scenario of sixteenth-century Italy, the paper addresses Aretino’s reaction to the anachronistic ideas of Pietro Bembo, which urge the author to promote a language derived from the experience of nature, in contrast with tradition. In such context, the Tuscan writer finds in Titian’s style his pictorial counterpart. An analysis of the principles that characterize the naturalistic poetics adopted by both painter and poet leads to a mutual comparison of Aretino’s Humanità di Christo and Titian’s depiction of Magdalen, where words and brushstrokes tend towards each other
Words For/Against Power. Pietro Aretino’s Poetical Devices as Demystification of the Present
No full textInvestigating the Ragionamento (1534) and the Dialogo (1536), this paper aims at reviewing Pietro Aretino’s relationship with power, both political and cultural. The author takes advantage of his poetical abilities as means of self-affirmation and political blackmail, developing between Rome and Venice a new poetic language, in which metaphor takes on a value that is anything but literary. Aretino wants to establish a concrete relationship with the recipients of his texts through the very act of writing. To do so, he credits the idea of a physicality and complete reality of all the elements that make the message possible, creating political images that reveal the vile nature of the corrupted authority
