Mitteleuropa oltre il mito. Rinuncia, nostalgia, il caso Moor
2019
The paper focuses on the co-existence of national identities, the concepts of Central Europe as a geographic space, and Mitteleuropa as a cultural space. In particular, it examines the development of a cultural unity need after the fall of the Austrian Empire, namely from the time of independent small states after the WWI, to the time of the iron curtain that reshaped the continent into two halves, West and East, thus delating the spirit of Mitteleuropa. As Milan Kundera wrote in 1983, at end of WWII the civil frame of Central Europe disappeared, and only the idea of a cultural community survived for a long time. On the one hand, the "nostalgia" of Mitteleuropa, and the new policy after the…
Recent trends in salmonellosis epidemiology
1999
The taxonomy of the genus Salmonella and the recent trends in the epidemiology of salmonellosis have been reviewed. Global and Italian trends in salmonellae infections have been considered focusing on the application of molecular biology methods to the study of epidemic isolates, as in the case of S. Wien and the more recent S. Enteritidis pandemics. Interventions for salmonellosis prevention, and control measures including new rapid cultural methods for the detection of salmonellae in foods, have been summarized.
Changes in Onset of Vegetation Growth on Svalbard, 2000–2020
2022
The global temperature is increasing, and this is affecting the vegetation phenology in many parts of the world. The most prominent changes occur at northern latitudes such as our study area, which is Svalbard, located between 76°30′N and 80°50′N. A cloud-free time series of MODIS-NDVI data was processed. The dataset was interpolated to daily data during the 2000–2020 period with a 231.65 m pixel resolution. The onset of vegetation growth was mapped with a NDVI threshold method which corresponds well with a recent Sentinel-2 NDVI-based mapping of the onset of vegetation growth, which was in turn validated by a network of in-situ phenological data from time lapse cameras. The results show th…
Lo spazio ospedaliero: criteri progettuali e tendenze in atto
2010
The research defines features and architectural qualities of the contemporary hospital buildings and focalizes the spaces supporting the therapeutic activity. The study of typological and theoretical contributions and the analysis of representative examples of recent architecture explain the meaning of the changes. A system of evaluating architectural qualities is useful to understand the future development and set up the guidelines for design.
La investigación cualitativa en las revistas españolas de ciencias del deporte (2007-2011)
2015
El objetivo de este estudio fue determinar el estado de la investigación cualitativa en las ciencias de la actividad física y del deporte en España, a partir del análisis de 1057 artículos publicados entre 2007 y 2011 en revistas españolas del campo indexadas en Scopus. Los resultados indican que sólo el 3.5% de los trabajos recurre a la metodología cualitativa y que en su mayor parte utilizan la entrevista como técnica de recogida de datos. Se señala como conclusión que la investigación cualitativa en las ciencias de la actividad física y el deporte en España se encuentra todavía en estado embrionario. The aim of this study was to determine the status of qualitative research in sport scien…
Multiple testing in candidate gene situations: a comparison of classical, discrete, and resampling-based procedures.
2011
In candidate gene association studies, usually several elementary hypotheses are tested simultaneously using one particular set of data. The data normally consist of partly correlated SNP information. Every SNP can be tested for association with the disease, e.g., using the Cochran-Armitage test for trend. To account for the multiplicity of the test situation, different types of multiple testing procedures have been proposed. The question arises whether procedures taking into account the discreteness of the situation show a benefit especially in case of correlated data. We empirically evaluate several different multiple testing procedures via simulation studies using simulated correlated SN…
A Modification of Stone's Test for Trend for Binary Outcome
1998
STONE (1988) suggested the first isotonic regression estimator as a tool for drawing inferences on possibly increased cancer case counts among several subregions around a putative source. He assumed the case counts to be Poisson distributed and therefore introduced a rare disease assumption into his approach. However, when analyzing cross sectional data one would rather refer to prevalence estimates among these subregions around a point risk source (for example the origin of chemical fallout). Therefore we applied antitonic regression estimation in Binomial distributions to derive a test statistic and a p value to test for a possible trend in the observed prevalence data around the putative…

2020
Il saggio esamina le nuove tendenze della legislazione in materia di rigenerazione urbanistica, con particolare attenzione alla vicenda urbanistica del Comune di Palermo.
Time Trends in the Joint Distributions of Income and Age
2001
We propose a method of analyzing time changes of joint income-age densities. Change is decomposed into time invariant components which act on the densities as deformations with time varying strength. The functional form of these components is estimated non parametrically from cross sectional data. The method is applied to analyze British household data on income and age for the years 1968–95. It is learned that for the young and middle aged there is a trend towards increasing inequality, while during the early eighties there seems to occur a reversal in the evolution of the income distribution for the old.
Tendencia temporal y variaciones geográficas de la prevalencia de síntomas de rinitis alérgica en escolares de 6-7 años de ocho áreas españolas, segú…
2005
Antecedentes: Se presenta la fase III del estudio ISAAC (International Study of Asthma and other Allergies in Childhood) en escolares de 6-7 años de ocho áreas españolas para estimar la tendencia temporal y variaciones geográficas de los síntomas de rinitis alérgica. Material y método: Se comparan las prevalencias de síntomas de rinitis alérgica entre la fase I y fase III, efectuadas entre los años 1993-1994 y 2001-2002, mediante un cuestionario estandarizado y validado según metodología ISAAC, cumplimentado por los padres de los escolares. Participaron ocho centros de Asturias, Barcelona, Bilbao, Cartagena, Castellón, Madrid, Pamplona y Valencia. Se empleó la regresión de Poisson en el aná…
