Ethnic segregation in a metropolitan area of Italy: the case of Palermo
2015
La segregazione residenziale etnica in Italia è una questione emergente, che sarà fondamentale nella definizione e attuazione di politiche urbanistiche e sociali. Questo articolo si focalizza sull’analisi del fenomeno nel comune di Palermo. Utilizziamo i dati della popolazione residente in città nel 2011 in tutti i quartieri suddivisa per etnia. Facciamo dapprima ricorso a tecniche di analisi spaziale tradizionale al fine di descrivere la segregazione residenziale degli stranieri e, tra le altre misure, calcoliamo l'indice di dissimilarità di Duncan e Duncan. Successivamente, applichiamo un approccio metodologico recentemente proposto in letteratura che consente di correggere la distorsione…
First measurement of proton's charge form factor at very low $Q^2$ with initial state radiation
2017
We report on a new experimental method based on initial-state radiation (ISR) in e-p scattering, in which the radiative tail of the elastic e-p peak contains information on the proton charge form factor ($G_E^p$) at extremely small $Q^2$. The ISR technique was validated in a dedicated experiment using the spectrometers of the A1-Collaboration at the Mainz Microtron (MAMI). This provided first measurements of $G_E^p$ for $0.001\leq Q^2\leq 0.004 (GeV/c)^2$.
Desinformando, que es gerundio. Trabajando con fake news en la clase de ELE
2022
El propósito de esta propuesta didáctica consiste en trabajar las cuatro destrezas de los estudiantes a través de fake news, haciendo especial hincapié en la expresión y comprensión escrita, al tiempo que se desarrolla la competencia informacional de los discentes. En cuanto al trabajo de la expresión escrita, este se centrará principalmente en la composición de noticias falsas, tanto de forma individual como colaborativa, empleando para ello procesadores de texto en línea y la autocorrección mediante retroalimentación indirecta.
Znaczenie rodziny w życiu skazanych poszkodowanych - opinie, oceny i potrzeby
2020
The questions addressed in the present paper concern the family relations of persons deprived of freedom who – remaining in the prison environment – have been degraded, that is convicts occupying the lowest rung in the informal penitentiary system, so-called victimized prisoners. They make a specific community, rejected and humiliated by other inmates. The necessity to ensure safety to them and help them protect their personal characteristics generates difficulties in activities of rehabilitative character. The aim of the research was to show the family relations of people degraded in the prison environment – a subject that has not been studied to date. The method of diagnostic survey was u…
Comparison of the accumulation of fibre breaks occurring in a unidirectional carbon/epoxy composite identified in a multi-scale micro-mechanical mode…
2010
National audience; A model to predict fibre break accumulation that takes into account all physical phenomena at the origin of the fibre break (i.e. the random nature, stress transfer due to breaks, fibre debonding and viscosity of the matrix) shows clearly that the failure of a unidirectional composite structure results in the formation of random fibre breaks which at higher loads coalesce into clusters of broken fibres. The object of the study is to experimentally confirm this scenario. Many techniques exist to detect the failure of carbon fibre composites, however none of them offer a resolution that allows this goal to be achieved in a non-destructive manner and in three dimensions.

BOTH MALE AND FEMALE SEXUAL ORNAMENTS REFLECT OFFSPRING PERFORMANCE IN A FISH
2010
Secondary sexual characters are often expressed in both sexes (mutual ornamentation), but are less often studied simultaneously. We studied the adaptive signaling function of male and female ornamentation in a mutually ornamented fish, the whitefish Coregonus lavaretus. In an experimental design in which nongenetic environmental effects were minimized, we found that highly ornamented females, males, and their parental combinations had offspring with better swimming performance and predator-avoidance ability than less ornamented individuals or combinations. Furthermore, highly ornamented females had larger offspring that also had higher yolk volume than less ornamented individuals. Offspring…
Autorità amministrative indipendenti e istituzioni politiche: questioni problematiche
2019
Le Autorità indipendenti rappresentano un modello di regolazione estraneo alla tradizione giuridica italiana, e, per questo, la loro collocazione ordinamentale ha suscitato, e continua a suscitare, dubbi e incertezze, riproponendo questioni fondamentali che appaiono tutt’altro che sopite. Inoltre, le dinamiche connesse al funzionamento delle Autorità indipendenti hanno evidenziato una notevole capacità evolutiva, per cui il loro ruolo ha conosciuto importanti mutamenti, assumendo caratteristiche diverse rispetto al funzionamento della forma di governo, e comportando nuovi assetti nelle relazioni con gli organi della legislazione, oltre che con gli organi della giurisdizione. Autonomia funzi…
Charge fluctuations and electric mass in a hot meson gas
2006
Net-Charge fluctuations in a hadron gas are studied using an effective hadronic interaction. The emphasis of this work is to investigate the corrections of hadronic interactions to the charge fluctuations of a non-interacting resonance gas. Several methods, such as loop, density and virial expansions are employed. The calculations are also extended to SU(3) and some resummation schemes are considered. Although the various corrections are sizable individually, they cancel to a large extent. As a consequence we find that charge fluctuations are rather well described by the free resonance gas.
Contrast sensitivity perimetry tests along the cardinal directions in color space: Correlation with the properties of the neural mechanisms mediating…
2014
It is well-known the advantages of measuring chromatic and achromatic contrast sensitivity for detecting pathologies. But these measurements are rarely used in clinical practice, due the complexity of the measurements and the examinator specialization. In fact, there is not a complete characterization of the response of the visual pathways to achromatic and chromatic spatio-temporal frequency stimuli. We have designed a new experimental device that facilitates these measurements and allow us to characterize the visual response in healthy patients. In this paper, we evaluated the responses of the visual pathways in healthy patients.
Inverting the Wollaston Illusion: Gaze Direction Attracts Perceived Head Orientation
2021
In the early 19th century, William H. Wollaston impressed the Royal Society of London with engravings of portraits. He manipulated facial features, such as the nose, and thereby dramatically changed the perceived gaze direction, although the eye region with iris and eye socket had remained unaltered. This Wollaston illusion can be thought of as head orientation attracting perceived gaze direction when the eye region is unchanged. In naturalistic viewing, the eye region changes with head orientation and typically produces a repulsion effect. Here we explore if there is a flip side to the illusion. Does the gaze direction also alter the perceived direction of the head? We used copies of the o…
