La competenza docimologica per la valorizzazione dei talenti. Una ricerca con i futuri docenti di scuola primaria e dell’infanzia

2018

Educating gifted students must be a priority for educators and education systems if society is to capitalise on their potential to contribute to an economical and sustain- able future. Given the importance of teachers in supporting academic achievement, educating preservice teachers on how to cater for gifted students commences the process as they can foster the implementation of current teaching practices that draw on sub- stantial research into the education of gifted children. If Evaluation process becomes an instrument for the development of talent in the classroom pre-service teacher training in docimological skill is necessary. In the ed- ucational field, talent and excellence find th…

Imparare ad abitare il mondo. Senso e metodo della relazione educativa

2015

Il testo propone una riflessione di pedagogia fondamentale sulla relazione educativa, svolta attraverso una descrizione fenomenologico-ermeneutica delle categorie di incontro, riconoscimento, consegna, dialogo, attenzione. Si perviene, nella prima parte del libro, ad una definizione dell'educazione come relazionalità riconoscente, processo nel quale è determinante il ruolo dell'empatia e il cui termine è l'apprendimento di una competenza estenziale. Nella seconda parte, viene evidenziato il senso che questa speciale forma di relazione può assumere nell'amore di coppia, nella vita di famiglia, nello studio, nella comunicazione tra le culture. Dall’antologia emerge come in ampi settori della …

L'attaccamento ai luoghi come modello interpretativo delle relazioni dell'uomo con la cultura. Una ricerca su un campione di ragazzi tunisini della c…

2014

L'attaccamento al luogo è un essenziale bisogno umano in grado di nutrire il senso dell'identità di individui e collettività, a prescindere dai cambiamenti della società. Intento principale in questo lavoro di tesi è quello dell'integrazione, legato al fenomeno dell' intercultura. Il lavoro di tesi è riferito nello specifico nella città di Mazara del Vallo, centro nevralgico di incontro di culture. Ho scelto di indagare la percezione del luogo da parte della popolazione immigrata, coinvolgendo in particolare gli adolescenti che costituiscono la cosiddetta "seconda generazione", e confrontandone le opinioni con quelle espresse dai coetanei autoctoni. L'aspetto più propriamente statistico rig…

Price dispersion, competition, and the role of online travel agents: Evidence from business routes in the Italian airline market

2014

Abstract In this article, using data from the Italian airline market, we study the role of online travel agents (OTAs) in driving price dispersion as compared to the effect of airlines’ websites. Specifically, we investigate how distinctive factors between OTAs and airlines’ direct channels influence price dispersion. We find that after controlling for OTAs’ features related to airline competition, price dispersion should be lower in the OTA channel relative to airlines’ direct channels. On the other hand, we also find that OTAs’ features related to the presence of airline competition play in favor of higher price dispersion in such indirect channel.

Upward and Downward Limit Pricing: The Role of Post-Entry Competition

2005

Under asymmetric information, entry-deterring strategies by an incumbent monopolist can consist of deviations from its static monopoly price through downward deviations termed downward limit pricing, or upward deviations termed upward limit pricing. Our analysis shows that the mode of post-entry competition influences the range of situations in which an incumbent adopts a strategy of downward limit pricing instead of an upward one: this range is greater under price than under output competition; it is decreasing in the degree of product differentiation; and with homogeneous product only downward limit pricing emerges under price competition, while upward limit pricing can still take place w…

An Scalable matrix computing unit architecture for FPGA and SCUMO user design interface

2019

High dimensional matrix algebra is essential in numerous signal processing and machine learning algorithms. This work describes a scalable square matrix-computing unit designed on the basis of circulant matrices. It optimizes data flow for the computation of any sequence of matrix operations removing the need for data movement for intermediate results, together with the individual matrix operations’ performance in direct or transposed form (the transpose matrix operation only requires a data addressing modification). The allowed matrix operations are: matrix-by-matrix addition, subtraction, dot product and multiplication, matrix-by-vector multiplication, and matrix by scalar multiplication.…

A saturated strategy robustly ensures stability of the cooperative equilibrium for Prisoner's dilemma

2016

We study diffusion of cooperation in a two-population game in continuous time. At each instant, the game involves two random individuals, one from each population. The game has the structure of a Prisoner's dilemma where each player can choose either to cooperate (c) or to defect (d), and is reframed within the field of approachability in two-player repeated game with vector payoffs. We turn the game into a dynamical system, which is positive, and propose a saturated strategy that ensures local asymptotic stability of the equilibrium (c, c) for any possible choice of the payoff matrix. We show that there exists a rectangle, in the space of payoffs, which is positively invariant for the syst…

Crowd-Averse Cyber-Physical Systems: The Paradigm of Robust Mean-Field Games

2016

For a networked controlled system, we illustrate the paradigm of robust mean-field games. This is a modeling framework at the interface of differential game theory, mathematical physics, and $H_{\infty}$ - optimal control that tries to capture the mutual influence between a crowd and its individuals. First, we establish a mean-field system for such games including the effects of adversarial disturbances. Second, we identify the optimal response of the individuals for a given population behavior. Third, we provide an analysis of equilibria and their stability.

A Bayesian unified framework for risk estimation and cluster identification in small area health data analysis.

2020

Many statistical models have been proposed to analyse small area disease data with the aim of describing spatial variation in disease risk. In this paper, we propose a Bayesian hierarchical model that simultaneously allows for risk estimation and cluster identification. Our model formulation assumes that there is an unknown number of risk classes and small areas are assigned to a risk class by means of independent allocation variables. Therefore, areas within each cluster are assumed to share a common risk but they may be geographically separated. The posterior distribution of the parameter representing the number of risk classes is estimated using a novel procedure that combines its prior …
