Résumé : International audience
We present a model of the spinal cord in controlling one degree-of-freedom arm movements. The model includes both neural and musculoskeletal functions in an integrated framework. The model has been implemented by an artificial neural network coupled with a computational model of muscle publicly available. The experimental results show that the model is able to regulate the position of the arm and to mediate reflex actions by integrating commands from CNS and signals from proprioceptors.

Résumé : International audience
Mobile-immobile mass transfer is widely used to model non-Fickian dispersion in porous media. Nevertheless, the memory function, implemented in the sink/source term of the transport equation to characterize diffusion in the matrix (i.e., the immobile domain), is rarely measured directly. Therefore, the question can be posed as to whether the memory function is just a practical way of increasing the degrees of freedom for fitting tracer test breakthrough curves or whether it actually models the physics of tracer transport. In this paper we first present a technique to measure the memory function of aquifer samples and then compare the results with the memory function fitted from a set of field-scale tracer tests performed in the same aquifer. The memory function is computed by solving the matrix diffusion equation using a random walk approach. The properties that control diffusion (i.e., mobile-immobile interface and immobile domain cluster shapes, porosity, and tortuosity) are investigated by X-ray microtomography. Once the geometry of the matrix clusters is measured, the shape of the memory function is controlled by the value of the porosity at the percolation threshold and of the tortuosity of the diffusion path. These parameters can be evaluated from microtomographic images. The computed memory function compares well with the memory function deduced from the field-scale tracer tests. We conclude that for the reservoir rock studied here, the atypical non-Fickian dispersion measured from the tracer test is well explained by microscale diffusion processes in the immobile domain. A diffusion-controlled mobileimmobile mass transfer model therefore appears to be valid for this specific case.

Résumé : Notre sujet de thèse porte sur la contribution des journalistes caribéens au processus démocratique à travers le traitement des événements socio-politiques majeurs entre 1989 et 2009. Il s’agit de la tentative du coup d’état de juillet 1990 à Trinidad-et-Tobago et du mouvement social de 2009 en Guadeloupe.Cette étude part d'un état des lieux des concepts de journaliste, de démocratie et de liberté de la presse. Cette thèse vise à interroger le terme « démocratie » et l'éthique des journalistes. Il existe des chartes déontologiques, édictées par la profession des journalistes, qui reprennent les principes démocratiques. Nous avançons donc l'hypothèse selon laquelle les journalistes sont de véritables acteurs du processus démocratique. Garants de la démocratie, ils ont aussi une responsabilité sociale envers les citoyens.Cette recherche vise à analyser les événements socio-politiques majeurs dans les deux territoires entre 1989 et 2009. A travers ces événements, il s'agit de montrer la manière dont les journalistes contribuent au processus démocratique. Notre méthodologie consiste à analyser les articles de presse et les entretiens semi-directifs avec les journalistes pour comprendre comment ils travaillent et comprendre leur concept de liberté de la presse.
The present research deals with the involvement of Caribbean journalists in the emergence of democracy through media coverage of the major socio-political events between 1989 and 2009. It is the attempted coup d’etat in Trinidad and Tobago in July 1990 and the social movement in Guadeloupe in 2009.This study starts by defining concepts such as journalists, democracy and freedom of the press. This thesis aims at examining the term “democracy” and journalists' ethics. There are democratic principles in the code of ethics written by journalists themselves. This leads me to think that journalists are indeed major actors in the democratic process. Indeed, they are the guarantors of democracy because they have a social responsibility towards citizens.This research aims at analyzing the major socio-political events in both territories between 1989 and 2009. Through these events, I would like to show the way journalists contribute to the democratic process. That is why I analyzed the articles of the newspapers and interviews with journalists were conducted, in order to know in detail the way they work and their concept of freedom of the press.

Résumé : On August 18th, 1967, H.M. Arvid Pardo, Malta's delegate at the UN, referred to the General Assembly with the question entitled: "Examination of the question of the reservation exclusively for peaceful purposes of the sea-bed and the ocean floor, and the subsoil thereof, underlying the high seas beyond the limits of present national jurisdiction, and the use of their resources in the interests of mankind." (1) This proposal was not the result of pure abstract thinking, but was, on the contrary, the wording of the necessity to adapt marine legislation to the current development state of the international society. However, this evolutive perspective does not exist only economically and technically speaking: it develops in the political field, especially in the development of the nations claim over marine spaces and the genesis of the principle of freedom of high seas. As in any dialectical perspective, legislation interferes with these de facto situations and imposes a number of directions to the study of a legal regime responding to the needs of a changing international society.
Le 18 août 1967, SE Arvid PARDO, représentant de Malte à l'ONU, saisit l'Assemblée Générale de la question intitulée : "Examen de la question de l'affectation à des fins exclusivement pacifiques du lit des mers ainsi que de leur sous sol, au-delà des limites de la juridiction nationale actuelle et de l'exploitation de leurs ressources dans l'intérêt de l'humanité". (1) Cette proposition n'était pas l'émanation d'une réflexion purement abstraite, mais traduisait au contraire la nécessité d'adapter le droit de la mer à l'état de développement de la société internationale. Cependant, cette perspective évolutive n'existe pas seulement sur le plan économique et technologique : elle se développe au niveau politique, particulièrement dans l'extension des prétentions étatiques sur les espaces maritimes et la genèse du principe de liberté de la haute mer. Comme dans toute perspective dialectique, le droit interfère sur ces situations de fait et impose donc a priori certaines orientations à l'étude d'un régime juridique répondant aux besoins d'une société internationale en pleine mutation.

Résumé : This study presents a unique database of 172 plagioclase Crystallographic Preferred Orientations (CPO) of variously deformed gabbroic rocks. The CPO characteristics as a function of the deformation regime (magmatic or crystal-plastic) are outlined and discussed. The studied samples are dominantly from slow- and fast-spread present-day ocean crust, as well as from the Oman ophiolite. Plagioclase is the dominant mineral phase in the studied samples. Plagioclase CPOs are grouped into three main categories: Axial-B, a strong point alignment of (010) with a girdle distribution of [100]; Axial-A, a strong point maximum concentration of [100] with parallel girdle distributions of (010) and (001); and P-type, point maxima of [100], (010), and (001). A majority of CPO patterns are Axial-B and P-type, in samples showing either magmatic or crystal-plastic deformation textures. Axial-A CPOs are less common; they represent 21% of the samples deformed by crystal-plastic flow. Although fabric strength (ODF J index) does not show any consistent variation as a function of the CPO patterns, there is a significant difference in the relationship between the ODF and pole figures J indices; the magmatic type microstructures have high (010) pole figures J indices, which increase linearly with ODF J index, whereas the high [100] pole figures J indices of plastically deformed samples vary in a more scattered manner with ODF J index. The multistage nature of plastic deformation superposed on a magmatic structure compared with magmatic flow, and the large number of possible slip-systems in plagioclase probably account for these differences. Calculated seismic properties (P wave and S wave velocities and anisotropies) of plagioclase aggregates show that anisotropy (up to 12% for P wave and 14% for S wave) tends to increase as a function of ODF J index. In comparison with the olivine 1998 CPO database, the magnitude of P wave anisotropy for a given J index is much less than olivine, whereas it is similar for S wave anisotropy. Despite a large variation of fabric patterns and geodynamic setting, seismic properties of plagioclase-rich rocks have similar magnitudes of anisotropy. There is a small difference in the aggregate elastic symmetry, with magmatic microstructures having higher orthorhombic and hexagonal components, whereas plastic deformation microstructures have a slightly higher monoclinic component, possibly correlated with predominant monoclinic simple shear flow in plastically deformed samples. Overall, plots for CPO strength (ODF J index), pole figure strength, CPO symmetry and seismic anisotropy show significant scattering. This could be related to sampling statistics, although our database is a factor of ten higher than the olivine database of 1998, or it could be related to the low symmetry (triclinic) structure of plagioclase resulting in the addition of degrees of freedom in the processes creating the CPOs.
