Se professionnaliser dans un dispositif de formation spécialisée
2013
Les nouvelles modalités de scolarisation des élèves handicapés interrogent les enseignants dans l’exercice de leur métier, en particulier ceux qui sont confrontés aux inscrits dans les troubles importants des fonctions cognitives. Les dispositifs de formation et d’accompagnement aident à identifier les compétences constitutives d’une nouvelle identité professionnelle enseignante et contribuent à initier et à enrichir ce processus de transformation identitaire. L’analyse des regards portés par les enseignants inscrits en formation spécialisée par alternance permet de mieux cerner les conditions requises afin que les leviers de transformation des postures et des pratiques professionnelles se …
How Do French Junior Secondary Schools Operate ? Academic Achievement, Grading and Streaming of Students
1989
International audience; This paper is concerned with the operation of Junior Secondary Schools in France. Students' school careers have been analysed in three sequential and cumulative components: student progress in learning in the junior secondary school, student grading by teachers, and student streaming, i.e., admission, or not, into a general form 3. For each of the three mechanisms described above, the authors examine whether they are influenced by the schooling context, which schooling context (school and/or classroom), and which characteristics of those contexts it is relevant to consider. Finally, they focus on the process by which the large social inequalities visible after the pu…
"Expanded" local mode approach and isotopic effect in polyatomic molecules
2014
In this thesis, on the base of the "expanded", local mode approach and general isotopic substitution theory we obtain sets of simple analytical relations between spectroscopic parameters (harmonic frequencies, anharmonic coefficients, ro-vibrational parameters, different kinds of Fermi and Coriolis-type interaction parameters) of the CH2D2, CH3D and CHD3 molecules. All of them are expressed as simple functions of spectroscopic parameters of the mother CH4 molecule. Test calculations with the isotopic relations show that even without including prior informations about the isotopic species, numerical results of calculations are in a good agreement both with experimental data and results of ab…

Thermodynamic limit of particle-hole form factors in the massless XXZ Heisenberg chain
2010
We study the thermodynamic limit of the particle-hole form factors of the XXZ Heisenberg chain in the massless regime. We show that, in this limit, such form factors decrease as an explicitly computed power-law in the system-size. Moreover, the corresponding amplitudes can be obtained as a product of a "smooth" and a "discrete" part: the former depends continuously on the rapidities of the particles and holes, whereas the latter has an additional explicit dependence on the set of integer numbers that label each excited state in the associated logarithmic Bethe equations. We also show that special form factors corresponding to zero-energy excitations lying on the Fermi surface decrease as a …
Stochastic algorithms for robust statistics in high dimension
2016
This thesis focus on stochastic algorithms in high dimension as well as their application in robust statistics. In what follows, the expression high dimension may be used when the the size of the studied sample is large or when the variables we consider take values in high dimensional spaces (not necessarily finite). In order to analyze these kind of data, it can be interesting to consider algorithms which are fast, which do not need to store all the data, and which allow to update easily the estimates. In large sample of high dimensional data, outliers detection is often complicated. Nevertheless, these outliers, even if they are not many, can strongly disturb simple indicators like the me…
Calcul direct d'une tesselation de la surface limite pour les schémas de subdivision uniformes
2017
International audience; Le peu d'utilisation des surfaces de subdivision dans les systèmes CAO est principalement lié au fait que la surface est le plus souvent seulement approchée par des niveaux de raffinement successifs, ce qui induit un manque de pré-cision. De plus, il est difficile d'intégrer la représentation des surfaces de subdivision dans le noyau géométrique (ensemble de primitives et d'outils) des applications CAO. C'est dans ce but que nous décrirons un formalisme général de construction de surfaces de subdivision basé sur les Systèmes Itérés de Fonctions. Le principal apport est que toutes les surfaces de subdivision classiques sont gérées de la même manière quel que soit le s…
