Dans nos sociétés en réseaux qui se caractérisent par un pluralisme normatif, on peut faire société sans partager des valeurs communes. Le fonctionnement des institutions scolaires illustre les nouveaux modes de régulation des tensions, de la diversité, de l'intégration, etc. désormais à l’œuvre. C'est dans ce contexte que le concept de médiation a fait son apparition dans nos écoles, comme dispositif d'apaisement ou de maintien du lien social. La diffusion de tels dispositifs doit beaucoup à la création de services centraux puis locaux de médiation, tout comme au travail de nombreux médiateurs qui ont progressivement investi le champ scolaire. Cet ouvrage constitue une exploration du développement de leur fonction et il rend compte de la culture professionnelle qui les anime. Cette exploration conduit à s'interroger sur le processus de diffusion de la médiation scolaire tout en contextualisant cette dernière dans le spectre plus large de la médiation en général, un concept désormais répandu dans les champs familiaux, judiciaires, sanitaires, administratifs, politiques et sociaux les plus divers.

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 ▲]

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.

Fengycin is characterized by its strong antifungal and low hemolytic activities. It has also been recently demonstrated that it has plant elicitor properties and is also able to enhance the elicitors’ activity of surfactin. The cell target of its biological activities is supposed to be plasma membrane. In spite of these interesting biological activities, fengycin has not been extensively investigated probably because of the difficulties related to its production. In a first time; we have characterized the interfacial properties of fengycin by tensiometry measurements and demonstrated that this surface activity was pH-dependent. In a second time; we have investigated the interactions of the lipopeptide with membrane lipids using model membranes such as Langmuir monolayers and multilammelar vesicles (MLVs). Our results indicate that the lipopeptide was able to penetrate into different lipid monolayers showing a preference for sterol-containing monolayers. In order to better understand the mechanism of the interactions of fengycin with membranes at the molecular level, MLVs with or without fengycin have been analyzed by spectroscopic techniques. We have shown that conformational changes of the lipopeptide occurred in the presence of lipids and they were more significant in the presence of sterol. Moreover, tyrosine residues of the lipopeptide seem to play an important role in these interactions. In conclusion, we have determined that the surface-active behavior as well as the conformation of fengycin depends on its environment. We have also showed that the lipopeptide does not interact with all class of lipids in the same way and presents a preference for sterols. The presence of key groups within peptide cycle has also been supposed for the biological activities of the lipopeptide. [less ▲]

From 2004 to 2009, two colonies of Malachite Kingfisher were monitored by ringing the nestlings and adults, counting eggs and observing parental activity at the nests. Results show that 10 % of nests were destroyed by people in the Symphonies site as against 78 % in the Monastery site. Consequently, the number of nests available for breeding is lower at Monastery than at Symphonies. The number of fledged chicks per nest at Symphonies was twice that at the Monastery. Site fidelity is higher for the adults in the Symphonies site (26 %) than at the Monastery (11 %). This suggests that the Monastery site is less favourable to the survival of the Malachite Kingfisher than the Symphonies site. The best strategy to protect this species seems to be the maintenance of a good number of nesting sites. [less ▲]

This paper aims at proposing a synthetic taxonomy of key success factors (KSF) for SME's in the luxury industry. Both typologies of KSF for SME's in overall on the one hand, and for companies of the luxury industry on the other hand, constructed on a basis of a critical literature review regarding the two domains concerned (SME's performance management and performance management of companies of the luxury industry) are gathered to propose a single synthetic taxonomy of KSF for SME's of the luxury industry.

Design of wind turbines requires the coupled analysis among the mechanical, control and aerodynamic subsystems. Different from previous research, which either uses a complicated mechanical model with a simple control system model, or vice versa, this paper studies the coupling of subsystems’ dynamics using a high-fidelity aeroelastic model of wind turbine and a detailed analytical model of control generating systems. A monolithic time integration approach is applied so that better numerical accuracy and stability are achieved. Control strategies on power optimization are discussed taking into account the influence of structural flexibility. Simulation examples are given on both stable and turbulent wind situation.
