Analizzare i dati connessi al settore dell’istruzione ha lo scopo di costruire un quadro su una delle principali trasformazioni delle migrazioni: l’incremento all’interno del sistema scolastico di alunni stranieri che costituisce un ricambio demografico delle coorti scolastiche.Nel saggio sarà presentata un’analisi delle presenze di alunni stranieri nei diversi ordini e gradi e nei differenti contesti territoriali della regione Sicilia, facendo riferimento in particolar modo agli ultimi dati di fonte Miur per l’A.S. 2016/2017.
Ivy and Bones: ruins and reversibility during the Blitz
2012
"Ivy and bones: ruins and reversibility during the Blitz" examines how the representation of the ruins of the Blitz is informed by the aesthetic and semiotic tension between abstraction, modernist purity and picturesque accretion. Subsequently building on the notion of reversibility, it explores the way wartime destruction and/or cultural decline is recorded as well as counteracted and compensated for in works by Elizabeth Bowen, Herbert Furst, Claire Leighton, Rose Macaulay, John Piper, and Virginia Woolf. The trope of reversibility provides a template to consider some of the sites where aesthetic conflicts are re-enacted, from blitzed spaces to the printed page as threatened modernist art…
Contrôle de nano-antennes optiques par une commande électrique : tuner plasmonique et transduction
2011
Optical nano-antennae are the new class of components to control light/matterinteraction at the nanoscale. These devices are operating in the visible to near infraredpart of the spectrum. The properties of these nano objects are controlled by theform, the size and the material.In the radio frequency domain, the tuner changes dynamically the operatingwavelength of the antenna. In this thesis work, we search to transfer this conceptto the nanoscale. The principle is to change the load impedance of the antenna, i.e.changing the optical index of the dielectric medium around the nano-object. Forthat we used anisotropic liquid cristal molecules. The value of the optical index iscontrolled by appl…

Les scolarités des enfants d'immigrés de la sixième au baccalauréat : différenciation et polarisation des parcours
2009
09024; Texte soumis à publication dans une revue à comité de lecture; Cet article revisite le débat sur la réussite scolaire des enfants d'immigrés en France, à partir du panel d'élèves entrés en 6ème en 1995 et suivis pendant dix ans. L'analyse complète des scolarités dans le secondaire, à travers les performances à l'entrée et à la fin du collège, les orientations au lycée puis les diplômes obtenus, fournit une image contrastée de ces parcours. Les élèves issus de l'immigration ont un niveau bien plus faible que les français d'origine à l'entrée en 6ème. Une grande partie des inégalités se joue dès le primaire, mais elles ne se creusent pas au collège. Les enfants de la seconde génération…
Le calendrier des inégalités d'accès à la filière scientifique
1999
International audience; The firts grade o french upper secondary school (lycée) is very important in terms of school careers, especially as regards with social and gender differenciations. This paper examines the process (periods and mechanisms) which explains the unequal access to scientific baccalauréat of boys and girls in one hand, and white and blue collar children in the other hand. The main differenciation is linked with the options courses choices which appear to be strongly determinant for the future school careers. School team answers to the demands expressed by the families in the middle and at the end of the school year also participate to these differenciations. They tend to re…
Self-portrait of an Orator as a Poet : images and Poetic references in Aelius Aristides' work
2022
Aelius Aristides is one of the major representatives of the Second Sophistic : his speeches are exemplary of the development of epidictic rhetoric in the imperial period. Everything in his work, including what he himself says on the subject, gives the image of an orator devoted body and soul to rhetoric and confident in the powers of prose. This is also the portrait that most studies since the 19th century have confirmed.However, poetry plays an important role in Aristide's speeches : they contain many poetic images and references. Moreover, Aristide writes poems and gives us fragments of them. He does not hesitate to refer to his own verses in speeches from both the beginning and the end o…
: Contextuel influence in choosing curriculum pathways in secondary schools : the school effect.
2004
The results of this research highlight the inequal nature of the process of choosing school careers upper secondary schools according to the school attended by the pupils, notably according to the social background within the school. If important social and academic differences appear in the pupils' study choice, they are mainly ratified by the staff (who tend even sometimes to emphasize them). Thus, the choice appears to be an internal process which come under the policy teach school, which consists in part in managing the social background of the pupils by allocating the later more or less equally between the different tracks available.
Coherent master equation for laser modelocking
2020
Modelocked lasers constitute the fundamental source of optically-coherent ultrashort-pulsed radiation, with huge impact in science and technology. Their modeling largely rests on the master equation (ME) approach introduced in 1975 by Hermann A. Haus. However, that description fails when the medium dynamics is fast and, ultimately, when light-matter quantum coherence is relevant. Here we set a rigorous and general ME framework, the coherent ME (CME), that overcomes both limitations. The CME predicts strong deviations from Haus ME, which we substantiate through an amplitude-modulated semiconductor laser experiment. Accounting for coherent effects, like the Risken-Nummedal-Graham-Haken multim…
