L'utilisation des reliefs naturels dans l'art gravé et sculpté pariétal du paléolithique supérieur français
2005
Pendant toute la durée du Paléolithique supérieur, en Espagne et en France principalement, les artistes ont réalisé des figurations en utilisant les reliefs naturels et la morphologie des parois de grottes ou d'abris-sous-roche. Ce phénomène artistique, qui a toujours préoccupé les préhistoriens, a suscité les interrogations et les interprétations les plus diverses de la fin du XIXe siècle jusqu'à présent : origine de l'art, préoccupations magico-religieuses, organisation spatiale et sanctuarisation de l'espace souterrain, structures pariétales, chamanisme, techno-cultures, etc. Pendant longtemps, ce que les formes rocheuses pouvaient avoir d'évocateur a été considéré comme la raison d'être…

STUDY OF THE INTERNAL DYNAMICS OF NON PLANAR PYRAMIDAL MOLECULES IN VIBRATIONALY VERY EXCITED STATES.
2007
From the U (p+1) formalism, we built a Hamiltonian adapted to the stretching modes of nonplanar XY3 molecules having the C3v group of geometrical invariance. This Hamiltonian is then coupled with two possible Hamiltonians describing the bending modes of these molecular system: a) based on the U (p+1) approach, a bending Hamiltonian is developed and the interaction between the bending and the stretching modes is taking into account through adapted 2:1 resonance coupling operator defined as a Us(4) x Ub(4) enveloping algebra operator ; b) based on the standard normal modes formalism, a bending modes Hamiltonian is expanded and the 2:1 interaction is taken into account as a tensorial product o…
Algebraic study of pyramidal molecules in the very excited vibrational states.
2005
In the frame of the algebraic formalism U(p+1), we developed the method to build a vibrational Hamiltonian corresponding to a set of three identical oscillators. In order to test the model, we apply it to the molecules of stibine and arsine. We introduce a supplementary intermediate group K(3) inspired by the similar formalism used in nuclear physics. This group K(3) gives additional labels for classification of the energy levels. The eigenvalues of these invariant operators distinguish the local states of the molecule. Then we study the coupling of the vibrational modes of stretching and bending for the non plane XY3 molecules. We present the construction of an algebraic operator of coupli…
Théorie des spectres rovibroniques des molécules octaédriques : Hamiltonien et moments de transition
2002
This thesis is devoted to the treatment of rovibronic couplings of octahedral species for which the Born-Oppenheimer approximation is broken down. By using the octahedral formalism, a full effective rovibronic model is extended from works about molecules in a non-degenerate electronic state. This effective model is dedicated to molecules with an odd or an even number of electrons and it has been successfully applied to V(CO)6 and ReF6. For both of them we have four interacting vibronic sublevels attributed to a dynamical Jahn-Teller effect and giving rise to very complicated spectra. This model is validated by the overall agreement between predicted and observed band profiles. Moreover, an …
Origins of the outperformance of venture backed initial public offerings : a French study
2010
In this thesis, we analyze the contractual relationship between private equity investors and entrepreneurs/managers of small and medium sized firms. More specifically, we focus on the real contribution of these financial intermediaries to the Initial Public Offering (IPO) performance of financed firms. While considering venture capitalists’ involvement in the governance of financed firms as the main explaining factor, we use the Corporate Governance theory as the relevant theoretical framework. Thus, we firstly point out the agency theory perspective and secondly the resource and knowledge based view perspective to examine the determinants of venture capitalists’ involvement and the impact …
Masculinité transnationale et corps-mâle dans les romans d’Abdellah Taïa
2016
I romanzi dello scrittore marocchino d'espressione francese Abdellah Taïa esaminano con attenzione la maschilità nel contesto migratorio. Omosessuale ed esiliato, Taïa cerca di costruire la sua identità sessuale secondo il modello occidentale; così facendo, contribuisce alla creazione di una maschilità islamica transnazionale che si decentra, pur restando ancorata all'eredità culturale delle sue terre d'origine. L'articolo si propone di interrogare le modalità di tale costruzione identitaria a partire dagli studi di Connell sulla maschilità egemonica e dalla psicoanalisi lacaniana applicata alla dimensione immaginaria del corpo. The novels of the French Moroccan writer Abdellah Taïa examine…
