Le but de ce chapitre est d’interroger le champ de l’accompagnement des demandeurs d’emploi comme étant ou non un marché conventionnel. Pour ce faire, les concepts de marché, de quasi-marché, de marché public et de champ sont clarifiés dans un premier temps. Pour comprendre le fonctionnement du marché de l’accompagnement, il est nécessaire dans un deuxième temps d’examiner quatre dimensions qui sont le périmètre et le financement de celui-ci mais également la sélection des opérateurs externes par les services publics de l’emploi et les stratégies développées par les différents acteurs appartenant à ce marché. L’étude de ces dimensions qui s’appuie sur trois études de cas permet de montrer la singularité du marché de l’accompagnement. [less ▲]

We report observations of the recently discovered, nearby late-M dwarf WISE J072003.20-084651.2. New astrometric measurements obtained with the TRAPPIST telescope improve the distance measurement to 6.0 ± 1.0 pc and confirm the low tangential velocity (3.5 ± 0.6 km s[SUP]-1[/SUP]) reported by Scholz. Low-resolution optical spectroscopy indicates a spectral type of M9.5 and prominent Hα emission (< {{log }[SUB]10[/SUB]}{{L}[SUB]Hα [/SUB]}/{{L}[SUB]bol[/SUB]}> = -4.68 ± 0.06), but no evidence of subsolar metallicity or Li i absorption. Near-infrared spectroscopy reveals subtle peculiarities that can be explained by the presence of a T5 binary companion, and high-resolution laser guide star adaptive optics imaging reveals a faint (ΔH = 4.1) candidate source 0\buildrel{\prime\prime}\over{.} 14 (0.8 AU) from the primary. With high-resolution optical and near-infrared spectroscopy, we measure a stable radial velocity of +83.8 ± 0.3 km s[SUP]-1[/SUP], indicative of old disk kinematics and consistent with the angular separation of the possible companion. We measure a projected rotational velocity of v sin i = 8.0 ± 0.5 km s[SUP]-1[/SUP] and find evidence of low-level variabilty (˜1.5%) in a 13 day TRAPPIST light curve, but cannot robustly constrain the rotational period. We also observe episodic changes in brightness (1%-2%) and occasional flare bursts (4%-8%) with a 0.8% duty cycle, and order-of-magnitude variations in Hα line strength. Combined, these observations reveal WISE J0720-0846 to be an old, very low-mass binary whose components straddle the hydrogen burning minimum mass, and whose primary is a relatively rapid rotator and magnetically active. It is one of only two known binaries among late M dwarfs within 10 pc of the Sun, both of which harbor a mid T-type brown dwarf companion. We show that while this specific configuration is rare (≲1.6% probability), roughly 25% of binary companions to late-type M dwarfs in the local population are likely low-temperature T or Y brown dwarfs. Some of the data presented herein were obtained at the W. M. Keck Observatory, which is operated as a scientific partnership among the California Institute of Technology, the University of California and the National Aeronautics and Space Administration. The Observatory was made possible by the generous financial support of the W. M. Keck Foundation. [less ▲]

Context. Planetary companions of a fixed mass induce reflex motions with a larger amplitude around lower-mass stars, which adds to making M dwarfs excellent targets for extra-solar planet searches. The most recent velocimeters with a stability of ~1 m s[SUP]-1[/SUP] can detect very low-mass planets out to the habitable zone of these stars. Low-mass small planets are abundant around M dwarfs, and most of the known potentially habitable planets orbit one of these cool stars. <BR /> Aims: Our M-dwarf radial velocity monitoring with HARPS on the ESO 3.6 m telescope at La Silla observatory makes a major contribution to this sample. <BR /> Methods: We present here dense radial velocity (RV) time series for three M dwarfs observed over ~five years: GJ 3293 (0.42 M[SUB]⊙[/SUB]), GJ 3341 (0.47 M[SUB]⊙[/SUB]), and GJ 3543 (0.45 M[SUB]⊙[/SUB]). We extracted these RVs through minimum χ[SUP]2[/SUP]-matching of each spectrum against a stack of all observed spectra for the same star that has a high signal-to-noise ratio. We then compared potential orbital signals against several stellar activity indicators to distinguish the Keplerian variations induced by planets from the spurious signals that result from rotational modulation of stellar surface inhomogeneities and from activity cycles. <BR /> Results: Two Neptune-mass planets - msin(i) = 1.4 ± 0.1 and 1.3 ± 0.1M[SUB]nept[/SUB] - orbit GJ 3293 with periods P = 30.60 ± 0.02 d and P = 123.98 ± 0.38 d, possibly together with a super-Earth - msin(i) ~ 7.9 ± 1.4 M[SUB]⊕[/SUB] - with period P = 48.14 ± 0.12d. A super-Earth - msin(i) ~ 6.1 M[SUB]⊕[/SUB] - orbits GJ 3341 with P = 14.207 ± 0.007d. The RV variations of GJ 3543, on the other hand, reflect its stellar activity rather than planetary signals. Based on observations made with the HARPS instrument on the ESO 3.6 m telescope under the program IDs 072.C-0488, 082.C-0718 and 183.C-0437 at Cerro La Silla (Chile).Tables A.1-A.3 (radial velocity data) are available in electronic form at <A href="http://www.aanda.org/10.1051/0004-6361/201424253/olm">http://www.aanda.org</A> and at the CDS via anonymous ftp to <A href="http://cdsarc.u-strasbg.fr">http://cdsarc.u-strasbg.fr</A> (ftp://130.79.128.5) or via <A href="http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/575/A119">http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/575/A119</A> [less ▲]

We report the discovery of the planets WASP-20b and WASP-28b along with measurements of their sky-projected orbital obliquities. WASP-20b is an inflated, Saturn-mass planet (0.31 M[SUB]Jup[/SUB]; 1.46 R[SUB]Jup[/SUB]) in a 4.9-day, near-aligned (λ = 12.7 ± 4.2°) orbit around CD-24 102 (V = 10.7; F9). Due to the low density of the planet and the apparent brightness of the host star, WASP-20 is a good target for atmospheric characterisation via transmission spectroscopy. WASP-28b is an inflated, Jupiter-mass planet (0.91 M[SUB]Jup[/SUB]; 1.21 R[SUB]Jup[/SUB]) in a 3.4-day, near-aligned (λ = 8 ± 18°) orbit around a V = 12, F8 star. As intermediate-mass planets in short orbits around aged, cool stars (7[SUP]+ 2[/SUP][SUB]-1[/SUB] Gyr and 6000 ± 100 K for WASP-20; 5[SUP]+ 3[/SUP][SUB]-2[/SUB] Gyr and 6100 ± 150 K for WASP-28), their orbital alignment is consistent with the hypothesis that close-in giant planets are scattered into eccentric orbits with random alignments, which are then circularised and aligned with their stars' spins via tidal dissipation. Based on observations made with: the WASP-South (South Africa) and SuperWASP-North (La Palma) photometric survey instruments; the C2 and EulerCam cameras and the CORALIE spectrograph, all mounted on the 1.2-m Euler-Swiss telescope (La Silla); the HARPS spectrograph on the ESO 3.6-m telescope (La Silla) under programs 072.C-0488, 082.C-0608, 084.C-0185, and 085.C-0393; and LCOGT's Faulkes Telescope North (Maui) and Faulkes Telescope South (Siding Spring).Full Tables 2 and 3 are only available at the CDS via anonymous ftp to <A href="http://cdsarc.u-strasbg.fr">http://cdsarc.u-strasbg.fr</A> (ftp://130.79.128.5) or via <A href="http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/575/A61">http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/575/A61</A> [less ▲]

Bone marrow stem cells are endowed with in vitro multi-lineage differentiation abilities, and constitute an attractive autologous source of material for cell therapy. With regards to recent findings, adult mesenchymal stem cells (MSC) are commonly assimilated to neural crest stem cells (NCSC), both isolated from adult bone marrow. The objective of this study was therefore to highlight significant differences for membrane markers between those two cell types. Using the minimal criteria for defining multipotent mesenchymal stromal cells as previously described by The International Society for Cellular Therapy, we were quite surprised that no significant difference could discriminate MSC from NCSC. To define new markers, we first performed a microarray comparison. Based on those results, we validated selected targets by RT-PCR, then by immunocytochemistry. In parallel, we observed that NCSC had the unique property (compared to MSC) to grow as spheres, which could also be used as a purification protocol for NCSC from adult bone marrow. Altogether, we demonstrated that P75NTR was the most significant discriminating marker between MSC and NCSC, isolated from mouse adult bone marrow, which could be used as selecting marker in an enrichment protocol. Sphere formation could then be used as a purification protocol for NCSC. [less ▲]

Despite an increasing number of interactomic datasets already available for model organisms and humans, many aspects remain contradictory, debatable or unclear due to the lack of complete high-quality networks. It has, for instance, been proposed that macromolecule connectivity in interactome maps reflects functional importance, functional relatedness, pleiotropy, implication in diseases, and other important biological characteristics. The most notorious example of such relationships concerns so-called essential genes believed to correspond to highly connected hubs that are critical to network integrity. Such claims have led to debate in the literature because connectivity could also be explained by bias and uneven coverage of the interactome space. To provide fresh insight into these questions, we produced a new, systematic interactome map for S. cerevisiae, organism for which a plethora of systematic interactomic and functional data is available. This alternative view of the interactome network was generated by modifying our screening pipeline based on our empirically-controlled framework. Using a new high-quality ORFeome collection and a new assay version, we systematically performed three replicate yeast-two hybrid screens. This produced a map of 1,200 protein-protein interactions, which, while of similar size as previously published interactome maps, covers the entire proteome without bias. These interactions were subsequently successfully validated using an orthogonal protein complementation assay based on a split Gaussia princeps luciferase. The latest analyses of this new map and progress towards generating a first Yeast Reference Interactome map will be presented. [less ▲]

Nous sommes tous bien conscients de la problématique liée au remodelage osseux après extraction dentaire, en particulier dans la zone esthétique. Les conséquences cliniques sont telles que le recours à des techniques de régénération tissulaire est souvent nécéssaire pour la pose de l'implant et pour assurer des résultats esthétiques. Cet article vise à démontrer l'efficacité d'un protocole d'optimisation tissulaire basé sur la préservation du capital osseux et sur l'optimisation des tissus gingivaux lors d'une extraction dentaire dans la zone esthétique. L'objectif de cet article est de suggérer un processus décisionnel en matière de technique chirurgicale, reposant d'une part sur l'examen clinique initial et, d'autre part, sur une excellente compréhension du concept biologique.

Recent research has shown that many prospective thoughts are organised in networks of related events, but the relational dimensions that contribute to the formation of such networks are not fully understood. Here, we investigated the organisational role of emotion by using cues of different valence for eliciting event networks. We found that manipulating the emotional valence of cues influenced the characteristics of events within networks, and that members of a network were more similar to each other on affective components than they were to members of other networks. Furthermore, a substantial proportion of events within networks were part of thematic clusters and cluster membership significantly modulated the impact of represented events on current well-being, in part through an intensification of the emotion felt when thinking about these events. These findings demonstrate that emotion contributes to the organisation of future thoughts in networks that can affect people’s well-being. [less ▲]

Voici trois siècles, il se racontait dans la ville prussienne de Königsberg qu’un promeneur ne pouvait pas traverser successivement les sept ponts reliant les différentes parties de la cité sans emprunter deux fois le même pont. Leonhard Euler apporta en 1736 une démonstration élégante de cette affirmation. Il produisit ainsi l’une des premières applications des mathématiques à la construction d’itinéraires optimisés. Aujourd’hui, la modélisation mathématique est devenue un outil indispensable pour les décideurs dans le monde du transport et, plus généralement, pour la gestion et la planification des activités logistiques. Qu’il s’agisse de calculer l’itinéraire le plus rapide de Liège à Marbella, d’optimiser les tournées de livraison d’une chaîne de grande distribution, de charger des navires ou des avions en assurant leur stabilité, de réduire les stocks excédentaires d’une entreprise pharmaceutique, de fixer le prix de billets de TGV en fonction des places disponibles, dans chaque cas, les mathématiques, alliées à l’informatique, permettent de formuler de façon précise le problème rencontré et d’y apporter des réponses pertinentes. Cet exposé présentera quelques applications typiques des mathématiques dans le domaine de la logistique et fournira un aperçu des méthodes qui y sont mises en œuvre. [less ▲]

The purpose of the present study was to explore the ability of neglect patients to detect and exploit the predictive value of a cue to respond more quickly and accurately to targets on their contralesional side in a Posner spatial cueing task. The majority of the cues (i.e. 80%) were invalid, indicating that the target would appear on the opposite side, although patients were not informed of this bias. Our results demonstrate that some neglect patients were able to extract the cue’s predictability and use it to orient faster toward the left. This cueing effect was present even in patients who were subsequently unable to describe the predictive character of the cues, and thus was not modulated by reportable awareness of the cue-target relation.

En vue d’assurer la cohérence de la politique de l’emploi sur le territoire bruxellois, le volet transversal du « Pacte de Croissance Urbaine Durable », appelé aussi « New Deal » bruxellois, inventorie une série d’actions à mettre en œuvre de manière coordonnée. Pour cela, il définit un cadre permettant de développer des partenariats entre acteurs aussi différents que des administrations, des partenaires sociaux ou encore des cabinets ministériels, dépendant d’institutions tantôt régionales, tantôt communautaires, francophones ou néerlandophones. Il repense ainsi l’organisation de la coordination entre ces acteurs, sans pour autant toucher à la répartition institutionnelle des compétences sur le territoire bruxellois. L’évaluation présentée dans ce Cahier de l’IBSA livre un bilan de l’utilité de ces dispositifs de coordination, selon le point de vue des acteurs impliqués. Elle repose sur une comparaison de huit études de cas qui portent sur une période d’observation de trois ans, allant d’avril 2011 à mars 2014.
