Under President Nicolas Sarkozy, France has embarked on a major defence transformation with far-reaching implications for relations with the United States, NATO and European defence more broadly. The new White Paper on French Security and Defence, released in June 2008 after months of internal debate, jettisons a number of precepts and policies that have dominated French defence thinking since the mid l960s. The most controversial change announced in the White Book is Sarkozy's decision to allow France to return to NATO's integrated military command, from which General de Gaulle withdrew France in l966. Sarkozy's decision to bring France back into the Alliance's integrated military structure would have significant security benefits both for France and NATO. It removes an important irritant that has hindered good relations between the United States and France and opens up new possibilities for improving US-European cooperation more broadly. Cooperation between NATO and the EU in particular should become easier with France inside NATO's integrated command. (Survival / SWP)

Measures to prevent vulnerable individuals from radicalizing and to rehabilitate those who have already embraced Islamist extremism have been implemented in several Middle Eastern, Southeast Asian, and European countries. This monograph describes and assesses the strengths and weaknesses of these programs and proposes steps that can be taken to promote and accelerate deradicalization processes

The often tense relationship between Saudi Arabia and Iran has been at the center of many of the major political shifts that have occurred in the Middle East since the fall of Saddam Hussein. This book surveys Saudi-Iranian relations since 2003, focusing on how they have affected and been affected by the major events in the Persian Gulf and the Levant, as well as the implications for U.S. policy in the region.

Dong, Hui et. al. ; Because of strong and spatially highly variable interstellar extinction and extreme source crowding, the faint (K ≥ 15) stellar population in the Milky Way's nuclear star cluster is still poorly studied. RR Lyrae stars provide us with a tool to estimate the mass of the oldest, relative dim stellar population. Recently, we analysed HST/WFC3/IR observations of the central 2.3 × 2.3 arcmin2 of the Milky Way and found 21 variable stars with periods between 0.2 and 1 d. Here, we present a further comprehensive analysis of these stars. The period- luminosity relationship of RR Lyrae is used to derive their extinctions and distances. Using multiple approaches, we classify our sample as 4 RRc stars, 4 RRab stars, 3 RRab candidates and 10 binaries. Especially, the four RRab stars show sawtooth light curves and fall exactly on to the Oosterhoff I division in the Bailey diagram. Compared to the RRab stars reported by Minniti et al., our new RRab stars have higher extinction (AK > 1.8) and should be closer to the Galactic Centre. The extinction and distance of one RRab stars match those for the Milky Way's nuclear star cluster given in previous works. We perform simulations and find that after correcting for incompleteness, there could be not more than 40 RRab stars within the Milky Way's nuclear star cluster and in our field of view. Through comparing with the known globular clusters of the Milky Way, we estimate that if there exists an old, metal-poor (-1.5 < [Fe/H] < -1) stellar population in the Milky Way nuclear star cluster on a scale of 5 × 5 pc, then it contributes at most 4.7 × 105 M⊙, i.e. ~18 per cent of the stellar mass. © 2017 The Authors. ; The research leading to these results has received funding from the European Research Council under the European Union's Seventh Framework Programme (FP7/2007-2013)/ERC grant agreement no [614922].

We used 4-yr baseline Hubble Space Telescope/Wide Field Camera 3 IR observations of the Galactic Centre in the F153M band (1.53 μm) to identify variable stars in the central ~2.3 arcmin × 2.3 arcmin field.We classified 3845 long-term (periods from months to years) and 76 short-term (periods of a few days or less) variables among a total sample of 33 070 stars. For 36 of the latter ones, we also derived their periods (< 3 d). Our catalogue not only confirms bright long period variables and massive eclipsing binaries identified in previous works but also contains many newly recognized dim variable stars. For example, we found δ Scuti and RR Lyrae stars towards the Galactic Centre for the first time, as well as one BL Her star (period < 1.3 d). We cross-correlated our catalogue with previous spectroscopic studies and found that 319 variables have well-defined stellar types, such as Wolf-Rayet, OB main sequence, supergiants and asymptotic giant branch stars. We used colours and magnitudes to infer the probable variable types for those stars without accurately measured periods or spectroscopic information. We conclude that the majority of unclassified variables could potentially be eclipsing/ellipsoidal binaries and Type II Cepheids. Our source catalogue will be valuable for future studies aimed at constraining the distance, star formation history and massive binary fraction of the Milky Way nuclear star cluster. © 2017 The Authors. ; The research leading to these results has received funding from the European Research Council under the European Union's Seventh Framework Programme (FP7/2007-2013) / ERC grant agreement no [614922].

Les objectifs du site P2Vie sont de mettre à profit les nouvelles technologies de l'information et de la communication pour réunir dans un système d'informations les éléments destinés au senior, permettant ainsi d'améliorer la prévention du vieillissement et d'optimiser la prise en charge des sujets dont l'état nécessite de recourir au système de soins. Plus spécifiquement, ce projet a permis de définir trois grands objectifs: la constitution d'un serveur d'informations médicales, celle d'un serveur d'informations socio-administratives et l'élaboration d'un carnet de santé électronique géré par le senior. Les perspectives attendues sont la mise en place d'un partenariat avec un site santé afin de proposer ce service au grand public.

How can we explain that some Popular education militants are also referring to the Information Society and thus seem to join this plan, carried to a great extent by merchants and the authorities ? Which are the stakes at work in this "meeting" ? Popular education, in addition to a long and plural history, is not homogeneous. However, Popular education is marked by a common philosophy aiming at developing social, cultural and political people's emancipation. In the mean time, political and economic authorities need to get the support of social actors to carry out the Information Society. Within this framework, associations would be the relay of the development of this society ; the necessary social mediator of this plan. Meanwhile, Popular education movements are seeking ways to appropriate this concept in order to make it able to serve the interests of Popular education. But they also question the specific purposes of this model. Indeed, the reference to the Information Society allows the militants of Popular education to update their traditional matters, and also to come out of the crisis they are facing. Lastly, if this meeting seems, at first sight, to generate consensus, the inherent conflicts in the confrontation of the values and identities do not therefore disappear and question the real stakes at work.
