Construction of migration project and reasons for emigrating in sub-Saharan African francophone population. An intercontinental study Europe-Africa

2012

Este estudio da cuenta de las razones de los ciudadanos de África subsahariana francófona para establecerse en Europa, y particularmente en Francia, mediante la creación de un marco comprensivo innovador que vincula tres ejes temáticos: la motivación, las migraciones, y África y sus relaciones con Europa. 155 participantes en ambos continentes respondieron a un cuestionario sobre su proyecto migratorio real o posible. Los resultados plantean un plano general de acercamiento a los imaginarios y la realidad de los migrantes en el contexto francés, marcado por la reflexión sobre la identidad nacional, los controles migratorios, un clima político reticente a la migración y un tejido social cara…

Enhancing Metastability by Dissipation and Driving in an Asymmetric Bistable Quantum System.

2018

The stabilizing effect of quantum fluctuations on the escape process and the relaxation dynamics from a quantum metastable state are investigated. Specifically, the quantum dynamics of a multilevel bistable system coupled to a bosonic Ohmic thermal bath in strong dissipation regime is analyzed. The study is performed by a non-perturbative method based on the real-time path integral approach of the Feynman-Vernon influence functional. We consider a strongly asymmetric double well potential with and without a monochromatic external driving, and with an out-of-equilibrium initial condition. In the absence of driving we observe a nonmonotonic behavior of the escape time from the metastable regi…

Highly occupied gauge theories in 2 + 1 dimensions : a self-similar attractor

2019

Motivated by the boost-invariant Glasma state in the initial stages in heavy-ion collisions, we perform classical-statistical simulations of SU(2) gauge theory in 2+1 dimensional space-time both with and without a scalar field in the adjoint representation. We show that irrespective of the details of the initial condition, the far-from-equilibrium evolution of these highly occupied systems approaches a unique universal attractor at high momenta that is the same for the gauge and scalar sectors. We extract the scaling exponents and the form of the distribution function close to this non-thermal fixed point. We find that the dynamics are governed by an energy cascade to higher momenta with sc…

Mi descrivi il tuo disegno del Mattoncino Lego? Un’esperienza didattica di matematica nella scuola dell’infanzia

2018

La consapevolezza dell’importanza di guardare, attraverso una lente di tipo matematico, i disegni prodotti dai bambini, considerandoli come strumento diagnostico per quello che D’Amore et al. (2004) chiamano come il “Campo di Esperienza” Spazio, Ordine e Misura, ha dato spunto a questo contributo che discute una sperimentazione didattica condotta in una sezione di scuola dell’infanzia (5 anni). All’interno della stessa è stato chiesto ai bambini di rappresentare dei mattoncini Lego con un disegno, e di descrivere successivamente i propri elaborati rintracciando e argomentando in essi eventuali segni di scarto numerico-spaziali rispetto al mattoncino osservato/manipolato, attraverso visioni …

Rappresentazioni tattili

2020

Sebbene molto spesso le persone con disabilità debbano accontentarsi di vivere parzialmente alcune esperienze, da diversi anni è aumentata l’attenzione dei siti museali verso la realizzazione di progetti e percorsi dedicati che consentano una fruizione tattile di opere e manufatti ai disabili visivi. Il contributo presenta due casi studio, che utilizzano modelli 3D per installazioni tattili. In presenza di deficit visivo, è importante rafforzare le facoltà percettive connettendo il tatto con i sensi residui e fornendo stimoli cognitivi diversi e paralleli. L’approccio multisensoriale, tattile e uditivo, realizzato grazie alla commistione tra modelli 3D e componenti elettroniche, favorisce l…

Harry Francis Mallgrave. L'empatia degli spazi. Architettura e neuroscienze

2015

Le informazioni che possiamo acquisire sul molteplice aspetto della realtà passano attraverso la percezione sensoriale che il nostro corpo ha dell’esterno. La relazione fra il corpo e l’architettura è proprio il tema centrale intorno al quale si snoda il libro di Harry Francis Mallgrave che, in quanto pioniere degli studi sull'applicazione delle neuroscienze alla teoria architettonica, svela attraverso "L’empatia degli spazi" la potenza e la forza del corpo nel costruire le forme della realtà. Information we can acquire on the multiple aspect of reality passes through sensory perception that our body has of the outside. The relationship between body and architecture is the central topic of …

Il disegno per la salvaguardia dell’architettura: la Centrale Termoelettrica di Giuseppe Samonà a Trapani

2019

Riflessioni grafiche per salvaguardare l’architettura. Nella Centrale Termoelettrica di Giuseppe Samonà, costruita a Trapani negli anni ’60, il concetto di spazio non inteso come mero luogo di lavoro, le relazioni armoniche che il manufatto instaura con il paesaggio, il linguaggio come esito del dualismo tra involucro e struttura e la lezione dei maestri del ‘900 sono tutti caratteri estrinsecabili attraverso il ridisegno critico. Un atto ermeneutico che tenta di definire il valore dell’edificio e diffonderne la conoscenza, al fine di scongiurarne l’oblio o, ancor peggio, la distruzione. Graphic reflections to safeguard the architecture. In the Thermoelectric Power Plant of Giuseppe Samonà,…

Intentionality of the Design Through the Redesign: Albanese House by Leone and Culotta

2020

Albanian house was designed in 1982 and takes its name from the one who commissioned the project from the studio of Culotta and Leone. The achievements of the study were studied, focusing in particular on the various projects related to single-family houses. Given the technological characteristics of the project, an analysis of the international context was also necessary, in particular the suggestions of the shingle style cottages were studied. In addition, the construction technology underlying the project, or the balloon frame, typical of the US context, was also studied. The project shows great attention to the exhibition, and to the relationship between inside and outside. The whole pr…

Representations of individuals in discourses of laïcité from Le Monde : confirming or challenging the republican framework of identity?

2017

In recent decades, the notions of laïcité and identity have been subjects of controversy in France. The two concepts have become sufficiently co-associated since the 1990s to ensure each almost systematically entails the other. Findings from previous studies have pointed out harmful implications of this pervasive association for minorities in France, especially Muslims. This study examines further the ways laïcité and identity are interwoven by exploring who is represented (and how) in newspaper articles from Le Monde dealing with laïcité. Informed by critical intercultural communication scholarship, intersectionality, and a Foucaultian approach to discourse, this study pays particular atte…

Cohabiting in Multiethnic Community: Forms, Representations and Images of the Diversity

2008

Modern culture, based on disinhibition of cultural trends and on heterodirection, is promoting openmindedness attitudes towards ethnic diversity, but on the other hand also new forms of social representations of the foreigner. Social representation is situated between the psychic field and the social one; it is the representation of oneself and of the other one, hanging between social categories and individual inner world. We will produce the results of a research on the representation of the foreigner, built on the type of prejudice prevailing among middle-low or middle-high educational qualification subjects, in which prejudicial attitudes seem to descend from precise mental images of the…
