Peppa Pig
2014
Peppa Pig è la regina delle serie tv rivolte per prima infanzia. Le sue puntate sono trasmesse in tv più di cinquanta volte al giorno da Rai YoYo e altri canali tv. Rappresentano un intrattenimento immancabile e, per certi versi, ineludibile per i piccoli. Il successo di Peppa Pig supera gli argini della programmazione televisiva ed è diventato fenomeno di costume, proliferando nei media più diversi (cinema, tv, internet e quant’altro). Estende anche il potere di fascinazione al mondo delle merci: Peppa si vende in ogni forma e modo, dai quaderni alle magliette, dai pupazzi ai gadget portatili. Peppa è diventata una metafora dei nostri tempi. Ma cosa davvero ci chiede la simpatica maialina …
Whence pseudoscience? An epidemiological approach
2017
In this paper, we develop an epidemiological approach to account for the typical features and persistent popularity of pseudoscience. An epidemiology of pseudoscience aims at explaining why some beliefs become widely distributed whereas others do not and hence seeks to identify the factors that exert a causal effect on this distribution. We pinpoint and discuss several factors that promote the dissemination of pseudoscientific beliefs. In particular, we argue that such beliefs manage to spread widely because they are intuitively appealing, manage to hitchhike on the authority of science, and successfully immunize themselves from criticism.

A methodological approach to analyze the territorial appropriation of high-speed rail from interactions between actions and representations of local …
2019
International audience; Because it is difficult to separate the specific transport impact from other factors influencing economic and spatial development, the focus in research is increasingly on understanding the process by which territorial changes occur in order to explain how economic and social agents and local authorities have appropriated new transportation systems. This appropriation plays a crucial part in territorial dynamics. The diversity of economic and spatial changes produced by high-speed rail indicates the existence of multiple modes of appropriation which vary according to the location of stations, the mobilization of local stakeholders confronted with the transport operat…
Les effets de la réforme sur le sentiment de professionnalisation des futurs enseignants
2013
S’inscrivant dans un cadre européen, la formation des enseignants en France fait l’objet, depuis 2005, de réformes profondes dont l’enjeu porte sur un renforcement des compétences professionnelles et un adossement des savoirs enseignés à la recherche. Partant de données longitudinales recueillies auprès de 3 générations d’étudiants inscrits dans le nouveau master « enseigner, éduquer, apprendre » ouvert à l’université de Bourgogne en 2010, cette recherche met en lumière la façon dont les étudiants se destinant au professorat des écoles perçoivent la qualité de leur professionnalisation. Malgré le sentiment de ne pas être suffisamment préparés pour l’exercice de leur métier, le discours des …
Les foyers de protection judiciaire de la jeunesse et la prise en charge des jeunes auteurs de délit : représentations sociales et réflexions autour …
2018
The educators’ work in juvenile justice residential communities and their capacity of affective attunement to the adolescent's needs is essential for the creation of a protective and enriching context for the adolescent and his life trajectories. This article aims to explore the social representations of educators and young people in residential communities in Italy, through the analysis of their discourses gathered during focus groups. Our results reveal the need to compare these representations and work to narrow the gap between the caregivers and the users, in order to improve the relationship between the different protagonists of the interaction and, consequently, the possibilities of g…
A Kato's second type representation theorem for solvable sesquilinear forms
2017
Kato's second representation theorem is generalized to solvable sesquilinear forms. These forms need not be non-negative nor symmetric. The representation considered holds for a subclass of solvable forms (called hyper-solvable), precisely for those whose domain is exactly the domain of the square root of the modulus of the associated operator. This condition always holds for closed semibounded forms, and it is also considered by several authors for symmetric sign-indefinite forms. As a consequence, a one-to-one correspondence between hyper-solvable forms and operators, which generalizes those already known, is established.
Separation of representations with quadratic overgroups
2011
AbstractAny unitary irreducible representation π of a Lie group G defines a moment set Iπ, subset of the dual g⁎ of the Lie algebra of G. Unfortunately, Iπ does not characterize π. If G is exponential, there exists an overgroup G+ of G, built using real-analytic functions on g⁎, and extensions π+ of any generic representation π to G+ such that Iπ+ characterizes π.In this paper, we prove that, for many different classes of group G, G admits a quadratic overgroup: such an overgroup is built with the only use of linear and quadratic functions.
Instruction-based clinical eye-tracking study on the visual interpretation of divergence : how do students look at vector field plots?
2018
Relating mathematical concepts to graphical representations is a challenging task for students. In this paper, we introduce two visual strategies to qualitatively interpret the divergence of graphical vector field representations. One strategy is based on the graphical interpretation of partial derivatives, while the other is based on the flux concept. We test the effectiveness of both strategies in an instruction-based eye-tracking study with N = 41 physics majors. We found that students’ performance improved when both strategies were introduced (74% correct) instead of only one strategy (64% correct), and students performed best when they were free to choose between the two strategies (88…
La presa in carico residenziale: percorsi di ricerca nelle comunità per minori.
2012
Le comunità residenziali possono essere concepite come “campi esperienziali”, luoghi di esperienza condivisa all’interno dei quali, nel qui e ora della quotidianità e nell’intreccio di storie, esperienze, culture, visioni del mondo, orientamenti e bisogni diversi, gli “abitanti” della comunità, minori e operatori, intrecciano reti relazionali complesse. L’esplorazione di tali campi esperienziali e del loro funzionamento, la definizione di setting di lavoro clinico e formativo nei quali avviare percorsi trasformativi, è l’interesse che ha mosso il progetto di ricerca e intervento che qui presentiamo. Nella prospettiva della valutazione del lavoro clinico e della qualità dei servizi offerti a…
