Pregiudizio classico e moderno nei confronti dei richiedenti asilo: un contributo alla validazione italiana della Prejudice Against Asylum Seekers Sc…
2021
In this study, we tested the validity of the Italian version of the Prejudice Against Asylum Seekers Scale (PAAS), which measures classic and modern prejudice toward asylum seekers. A sample of 740 participants (227 males and 513 females, aged 18-67) completed the scale. The results were consistent with the original 2-factor model providing an acceptable fit for the data. This study, however, suggests taking out two items from the scale. The two correlated factors showed significant associations with right-wing authoritarianism, social dominance orientation, and national identification. No gender differences emerged, but only those related to religious affiliation, age, and political orient…
Orientation and Alignment Echoes
2015
We present one of the simplest classical systems featuring the echo phenomenon---a collection of randomly oriented free rotors with dispersed rotational velocities. Following excitation by a pair of time-delayed impulsive kicks, the mean orientation or alignment of the ensemble exhibits multiple echoes and fractional echoes. We elucidate the mechanism of the echo formation by the kick-induced filamentation of phase space, and provide the first experimental demonstration of classical alignment echoes in a thermal gas of ${\mathrm{CO}}_{2}$ molecules excited by a pair of femtosecond laser pulses.
Antigüedad clásica y cultura nobiliaria en la España de finales del siglo XVIII. Autores y ediciones greco-romanas en la biblioteca de José Alvarez d…
2019
This article analyzes the reception of the classical world in the Spanish nobiliary culture at the end of the 18th century. Our objective is materialized through the study of the Greco-Roman books present in the unpublished catalog of the library of José Álvarez de Toledo, 11th Marqués de villafranca. From the examination of the authors and the different editions conserved by the aristocrat, the work tries to examine the influence of the classical world and its actuality in the development of the most advanced nobiliary culture of eighteenth- century Spain.
Turán type inequalities for generalized inverse trigonometric functions
2013
In this paper we study the inverse of the eigenfunction $\sin_p$ of the one-dimensional $p$-Laplace operator and its dependence on the parameter $p$, and we present a Tur\'an type inequality for this function. Similar inequalities are given also for other generalized inverse trigonometric and hyperbolic functions. In particular, we deduce a Tur\'an type inequality for a series considered by Ramanujan, involving the digamma function.
Verso una dimensione narrativa delle mappe
2021
Tra il pensiero e la costruzione dell’architettura il disegno ha un ruolo baricentrico per connettere i diversi protagonisti di una realizzazione e per coinvolgere la collettività facendo percepire inedite prospettive. La scrittura si rivela utile per esplicitare ciò che nella grafica è sotteso e per stabilire un ordine nuovo nel ragionamento progettuale. I rapporti fra segni e significati si moltiplicano nei sistemi informativi recenti in cui si ha la sensazione di poter dire moltissimo (dati numerici e spaziali) ma a volte sfugge quella sintesi indispensabile per una interpretazione concreta, finalizzata alla costruzione di possibili esperienze fisiche. Per l’esplorazione dell’uso di dive…
Psychological Approaches to Origins and Treatments of Somatoform Disorders
2010
Medically unexplained symptoms are the defining feature of somatoform disorders (SFD) as currently included in Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, and the International Classification of Diseases, Tenth Edition. Cognitive, behavioral, biological, and social variables are important to our understanding of SFD. Research in the past decade has highlighted the central role of (a) prolonged attention allocation to bodily sensations, (b) the dysfunctional role of catastrophizing symptoms as signs of severe illness, (c) neuroendocrine alterations, and (d) the influence of illness behavior (e.g., the avoidance of physical activity) on the maintenance and chronici…
Oscillatory integrals and fractal dimension
2021
Theory of singularities has been closely related with the study of oscillatory integrals. More precisely, the study of critical points is closely related to the study of asymptotic of oscillatory integrals. In our work we investigate the fractal properties of a geometrical representation of oscillatory integrals. We are motivated by a geometrical representation of Fresnel integrals by a spiral called the clothoid, and the idea to produce a classification of singularities using fractal dimension. Fresnel integrals are a well known class of oscillatory integrals. We consider oscillatory integral $$ I(\tau)=\int_{; ; \mathbb{; ; R}; ; ^n}; ; e^{; ; i\tau f(x)}; ; \phi(x) dx, $$ for large value…
C1-esterase inhibitor in ischemia and reperfusion.
2002
Summary Myocardial injury from ischemia can be aggravated by reperfusion of the jeopardized area. The precise underlying mechanisms have not been clearly defined, but proinflammatory events including complement activation play important roles. Cardioprotection by complement inhibition inter alia C1-esterase-inhibitor (C1-INH) was examined in several experimental models and under clinical conditions with ischemia and reperfusion. C1-INH reduced local anaphylatoxin release revealing the importance of the classical complement pathway. Inhibition of local complement activation was accompanied by improvement of myocardial function and perfusion of the previously ischemic myocardium. Leukocyte en…
A Lagrangian method for deriving new indefinite integrals of special functions
2015
A new method is presented for obtaining indefinite integrals of common special functions. The approach is based on a Lagrangian formulation of the general homogeneous linear ordinary differential equation of second order. A general integral is derived which involves an arbitrary function, and therefore yields an infinite number of indefinite integrals for any special function which obeys such a differential equation. Techniques are presented to obtain the more interesting integrals generated by such an approach, and many integrals, both previously known and completely new are derived using the method. Sample results are given for Bessel functions, Airy functions, Legendre functions and hype…
Interpositus nucleus inactivation reduces unconditioned response amplitude after paired but not explicitly unpaired treatment in rabbit eyeblink cond…
2001
The amplitude of unconditioned responses (URs) in unconditioned stimulus (US) alone presentations were measured in six rabbits during explicitly unpaired and classical conditioning treatments. After both phases of the experiment, the interpositus nucleus (IPN) was reversibly inactivated by a cold probe. URs after unpaired treatment were unaffected by inactivation but after acquisition of a robust level of conditioned responses (CRs), URs in US-alone test trials were reduced in amplitude compared with URs immediately before and after inactivation. The results suggest that the IPN has a role in CR-related reflex modification.
