Cet article analyse les enjeux dissimulés derrière une polémique qui a débuté suite à un article de François Busnel, publié le 24 novembre 2010 dans l’Express-Lire, dans lequel ce dernier dénigre la littérature jeunesse et l’accuse de n’être qu’un "coup marketing". Cette publication a déclenché de nombreuses réactions chez les représentants de ce secteur. L'analyse proposée ici tâche de rendre compte, en confrontant les deux types de prises de parole, de l’impact que peut avoir l’objet d'une polémique (la littérature jeunesse, dans ce cas-ci) sur le déroulement de celle-ci.

S’il est un élément précoce de la socialisation politique des jeunes Belges, c’est la connaissance de l’obligation de voter dans ce pays. Peu de Belges ignorent, en effet, que le vote y est obligatoire et donc qu’une obligation de se rendre aux urnes, sous peine de sanctions – généralement peu ou mal connues –, incombe à chaque électeur du Royaume, même si dans les faits tous ne participent au scrutin. Pourtant, le vote obligatoire n’est pas une caractéristique commune des systèmes électoraux à travers le monde. À ce jour, on ne retrouve une telle obligation, assortie ou non de sanction, que dans trente et un États ou partie d’État. La Belgique fut précurseur en la matière et, même si ce pays ne s’est pas détourné du vote obligatoire en plus de cent ans d’existence, cette obligation continue de susciter un véritable débat. Dans la première partie de ce chapitre, nous revenons sur l’introduction du vote obligatoire en Belgique en présentant les arguments de ce débat. La deuxième partie aborde les principes et les sanctions consacrés par le droit positif tandis que la troisième partie explore les conséquences politiques du vote obligatoire. Tout naturellement, la conclusion de ce chapitre se penchera sur son avenir en Belgique. [less ▲]

Historically, the name of Natural Killer (NK) cells came from their natural ability to kill tumor cells in vitro. From the seventies to date, accumulating data highlighted the importance of NK cells in host immune response against cancer and in therapy-induced anti-tumor response. The recognition and the lysis of tumor cells by NK cells are regulated by a complex balance of inhibitory and activating signals. This review summarizes NK cell mechanisms to kill cancer cells, their role in host immune responses against tumor growth or metastasis and their implications in anti-tumor immunotherapies via cytokines, antibodies or in combination with other therapies. The regulatory role of NK cells in autoimmunity is also discussed. [less ▲]

As a result of the decentralization of health systems, some countries have introduced intermediate (provincial) levels in their public health system. This paper presents the results of a case study conducted in Kinshasa on health system decentralization. The study identified a shift from a focus on regulation compliance assessment to an emphasis on health system coordination and health district support. It also highlighted the emergence of a?managerial (as opposed to a bureaucratic) approach to health district support. The performance of health districts in terms of health care coverage and health service use were also found to have improved. The results highlight the importance of intermediate levels in?the health care system and the value of a more organic and managerial rationality in supporting health districts faced with the complexity of urban environments and the integration of specialized multi-partner programs and interventions.

Finite element models accurately compute the mechanical response of bone and bone-like materials when the models include their detailed microstructure. The aim of this paper is to develop and validate a biomechanical model for deer antler cancellous bone tissue based on X-ray microtomographic images. In order to simulate the mechanical behavior under compressive load using a finite element model, images obtained by X-ray microtomography were exported into Metafor, which is an non-linear finite element software initially developed at University of Liège for metal forming processes. This software has recently found biomedical applications. The ultimate goal is to compare model predictions with the mechanical behavior observed experimentally using the Skyscan material testing stage under compression mode. The creation of the biomechanical model mesh from segmented μCT images, its integration into the software Metafor and the simulation of a compression test are described in this paper. [less ▲]

Aims: We aim to investigate the long-term temporal evolution of the magnetic field of the solar-type star ξ Bootis A, both from direct magnetic field measurements and from the simultaneous estimate of indirect activity indicators. Methods: We obtained seven epochs of high-resolution, circularly-polarized spectra from the NARVAL spectropolarimeter between 2007 and 2011, for a total of 76 spectra. Using approximately 6100 photospheric spectral lines covering the visible domain, we employed a cross-correlation procedure to compute a mean polarized line profile from each spectrum. The large-scale photospheric magnetic field of the star was then modelled by means of Zeeman-Doppler Imaging, allowing us to follow the year-to-year evolution of the reconstructed magnetic topology. Simultaneously, we monitored the width of several magnetically sensitive spectral lines, the radial velocity, the line asymmetry of intensity line profiles, and the chromospheric emission in the cores of the Ca II H and Hα lines. Results: During the highest observed activity states, in 2007 and 2011, the large-scale field of ξ Bootis A is almost completely axisymmetric and is dominated by its toroidal component. The toroidal component persists with a constant polarity, containing a significant fraction of the magnetic energy of the large-scale surface field through all observing epochs. The magnetic topologies reconstructed for these activity maxima are very similar, suggesting a form of short cyclicity in the large-scale field distribution. The mean unsigned large-scale magnetic flux derived from the magnetic maps varies by a factor of about 2 between the lowest and highest observed magnetic states. The chromospheric flux is less affected and varies by a factor of 1.2. Correlated temporal evolution, due to both rotational modulation and seasonal variability, is observed between the Ca II emission, the Hα emission and the width of magnetically sensitive lines. The rotational dependence of polarimetric magnetic measurements displays a weak correlation with other activity proxies, presumably due to the different spatial scales and centre-to-limb darkening associated with polarimetric signatures, as compared to non-polarized activity indicators. Better agreement is observed on the longer term. When measurable, the differential rotation reveals a strong latitudinal shear in excess of 0.2 rad d-1. [less ▲]

This paper provides a new, exact controller for formation-keeping in the presence of attitude tracking requirements. Both orbital and attitude dynamics are simultaneously considered and continuous thrust propulsion systems are assumed. A leader satellite is assumed to be in a given Keplerian orbit around a central body and each follower satellite is required to stay in a prescribed, desired orbit with respect to the leader satellite, and at the same time, to exactly point to a specific spot in inertial space that may be fixed or time varying. The satellites are considered as rigid-bodies and for attitude dynamics quaternions are used to realize arbitrary orientations and avoid singularities. Unlike most studies, no linearizations and/or approximations are made in dynamics or the controllers. It is hoped that the novel controller provides a remarkable improvement over the current state-of-the-art in that the control force and torque to satisfy the given orbital and/or attitude constraints are obtained in completely closed form. This new, analytical solution can be easily used for on-orbit, real-time control with low computational burden. Furthermore, it is useful in estimating the magnitude of the required control inputs and results in some interesting consequences, including the separation principle, which describes when the orbital control can be completely decoupled from the attitudinal control required to be applied to the follower satellite. Extensive computational simulations are performed to demonstrate the simplicity of implementation and accuracy of the control method developed herein. [less ▲]

In both elasticity and poroelasticity, the nucleus of strain is usually used to refer to a singular solution such as the point force, the force dipole, the centers of rotation and dilation, etc. These fundamentals solutions constitute the building blocks for various problems of practical importance and are, therefore, relatively well understood. However, a comparison of the original elastic solution for the center of dilation with the classic Lamé solution reveals an unexpected dependence of the center of dilation solution on the Poisson’s ratio. This inconsistency is investigated by means of two alternative representations of the singularity and leads to the identification of a compressed zone inside the singularity. The poroelastic equivalent to this nucleus of strain is shown to be the superposition of the elastic one with drained material parameters and an instantaneous point fluid source associated with a finite volume of fluid that is expelled from the compressed region inside the singularity and is injected in the porous medium.
