La diffusion de la notion de 'formation tout au long de la vie' dans les discours politiques amène à un renouvellement des interrogations sur la formation continue des adultes. Les outils de mesure se sont progressivement adaptés à cette nouvelle donne; c'est le cas de l'Enquête sur les Forces de Travail (EFT) d'Eurostat mise en oeuvre en Belgique par l'INS. Grâce à l'exploitation inédite de certaines variables de l'enquête, nous avons voulu approcher les dynamiques individuelles qui sous-tendent la participation à diverses formes de formation continue. Ces dynamiques peuvent en effet être abordées sous l'angle de l'accès, de l'investissement en temps et des objectifs poursuivis par les personnes, mais également par le biais des résultats obtenus, par exemple, en termes d'amélioration du niveau de qualification. En amont et en aval du processus de formation, motivations initiales et situations sur le marché du travail peuvent aussi permettre de mieux cerner le fonctionnement de la formation continue.

In the North Sea Ekofisk oilfield, oil is located in a 300 m thick layer of porous chalk (n = 40-50%) at a 3000 m depth. After the initial phase of depletion an enhanced oil recovery procedure was carried out by injecting sea water (waterflooding). An unexpected consequence of this waterflooding has been the occurrence of a seafloor subsidence, corresponding up to now to a decrease of the seafloor level of approximately 10 m. It is now well recognised that hydro-mechanical coupling involving multiphase fluid interactions (oil and water) is determinant for the interpretation of the phenomenological aspects associated with the chalk compaction and the related subsidence observed in the North Sea oilfields (Ekofisk reservoir) when water flooded. The subsidence due to waterflooding is interpreted as a collapse phenomenon due to suction decrease, typical of loose and low plasticity unsaturated soils when wetted under load. On the other hand, time-dependent stress-strain behaviour of geomaterials is one of the major concerns in soil mechanics and, in effect, subsidence includes creep effects. A multiphase approach, including creep effects under controlled suction levels, is proposed in this paper; the preliminary results of this study are presented and discussed. Attention will be focused at first on the theoretical approach, supplying the essential elements for the work, and on the interpretation of the experimental results. This will provide secondly the base for formulation and validation of the constitutive law proposed for the description of the time-dependent mechanical behaviour of the chalk. [less ▲]

We present a method to evaluate the pion structure functions from a box diagram calculation. Pion and constituent quark fields are coupled through the simplest pseudoscalar coupling. The gamma^* pi -> q \bar q cross-section is evaluated and related to the structure functions. We then show that the introduction of non-perturbative effects, related to the pion size and preserving gauge invariance, provides us with a straighforward relation with the quark distribution. It is predicted that higher-twist terms become negligible for Q^2 larger than about 2 GeV^2 and that quarks in the pion have a momentum fraction smaller than in the proton. We enlarge the discussion concerning this violation of the momentum sum rule, emphasizing that the sum rule is recovered in the chiral limit and also when the finite size condition is not imposed.

Our ability to recognise the usual horizontal orientation Of Our own face (mirror orientation) as compared with another very familiar face (normal orientation) was examined in experiment 1. Participants did not use the same kind of information in determining the orientation of their own face as in determining the orientation of the other familiar face. The proportion of participants who reported having based their judgment on the location of an asymmetric feature (eg a mole) was higher when determining the orientation of their own face than when determining that of the other familiar face. In experiment 2, participants were presented with pairs of manipulated images of their own face and of another familiar face showing conflicting asymmetric features and configural information. Each pair consisted of one picture showing asymmetric features of a given face in a mirror-reversed position, while the facial configuration was left unchanged; and one picture in which the location of the asymmetric features was left unchanged, while the facial configuration was mirror-reversed. As expected from the hypothesis that asymmetric local features are more frequently used for the judgment of one's own face, participants chose the picture showing mirror-reversed asymmetric features when determining the usual orientation of their own face significantly more often than they chose the picture showing normally oriented asymmetric features when determining the orientation of the other face. These results are explained in terms of competing forward and mirror-reversed representations of one's own face. [less ▲]

We have measured the in-plane anisotropy of the vortex mobility in a thin Pb film with a square array of antidots. The Lorentz force, acting on the vortices, was rotated by adding two perpendicular currents and keeping the amplitude of the net current constant. One set of voltage probes was used to detect the vortex motion. We show that the pinning landscape provided by the square antidot lattice influences the vortex motion in two different ways. First, the modulus of the vortex velocity becomes angular dependent with a lower mobility along the diagonals of the pinning array. Second, the vortex displacement is preferentially parallel to the principal axes of the underlying pinning lattice, giving rise to a misalignment between the vortex velocity and the applied Lorentz force. We show that this anisotropic vortex motion is temperature dependent and progressively fades out when approaching the normal state. [less ▲]

La confrontation de la structuration de base du système politique européen au vécu des jeunes réfugiés albanophones et aux discours qu'ils produisent amène à poser la question de leur double affiliation d'origine et d'arrivée en cherchant une solution dans une dynamique de transfert mimétique du groupe de référence au groupe d'apartenance. Deux modèles se dégagent de cette confrontation, l'un "Léonardo di Caprio" composé d'un hybride incarnant les migrations et le rêve américano-européen de l'acquisition d'une force de travail échangeable sur le marché du travail mondial et l'autre "Mohammed Atta", hétéroéférentiel cherchant à passer inaperçu dans les mailles du contrôle de la richesse, jouant la banalité pour poser un acte de révolte.

BACKGROUND: It is commonly stated that risk factors for postoperative nausea are the same as for vomiting. The authors designed a prospective study to identify and differentiate the risk factors for postoperative nausea and vomiting in various surgical populations in a clinical audit setting. METHODS: The study included 671 consecutive surgical inpatients, aged 15 yr or more, undergoing various procedures. The study focused on postoperative nausea visual analog scale scores every 4 h and vomiting episodes within 72 h. Both vomiting and retching were considered as emetic events. Patient-, anesthesia-, and surgery-related variables that were considered to have a possible effect on the proportion of patients experiencing postoperative nausea and/or vomiting were examined. The bivariate Dale model for binary correlated outcomes was used to identify selectively the potential risk factors of postoperative nausea and vomiting. RESULTS: Among the 671 patients in the study, 126 (19%) reported one or more episodes of nausea, and 66 patients (10%) suffered one or more emetic episodes during the studied period. There was a highly significant association between the two outcomes. Some risk factors were predictive of both nausea and vomiting (female gender, nonsmoking status, and general anesthesia). History of migraine and type of surgery were mainly responsible for nausea but not for vomiting. The predictive effect of risk factors was controlled for postoperative pain and analgesic drugs. CONCLUSION: This study shows that differences exist in risk factors of postoperative nausea and vomiting. These could be explained by differences in the physiopathology of the two symptoms. [less ▲]

This study describes for the first time the development and validation of a sensitive and specific radioimmunoassay (RIA) for equine osteocalcin (OC) quantification using purified equine OC as standard, tracer, and immunogen for antibody formation in rabbits. The assay allowed to measure equine serum OC levels with a sensitivity of 0.2 ng/mL. Immunoreactive serum OC values of clinically normal, different-aged horses ranged from 3.68 to 127.31 ng/mL. Intra- and inter-assay coefficients of variation (CV) were 6.2 and 8.2%, respectively. Serial equine scrum sample dilutions were linear. The recovery of equine OC from equine serum samples ranged from 93.88 to 107.9%. There was a tight correlation between OC values measured with the equine- specific OC RIA and two commercially available bovine-specific OC RIA kits. However, highest serum OC values were obtained with the equine-specific OC RIA. In conclusion, our equine-specific OC RIA is sensitive, linear, accurate, precise, and reproducible. The assay allowed to quantify OC in equine serum samples and might, therefore, be used to monitor equine osteoblast activity associated with bone diseases, exercise, therapy forms or diet. [less ▲]

The Rogaland Anorthosite Province comprises three major massif-type anorthosites, two smaller-sized anorthositic-leuconoritic bodies, as well as a large layered, dominantly noritic intrusion. A mangero-noritic intrusion is found in the northeastern part of the province and major acidic intrusions are located to the far southeast. The Rogaland Anorthosite Province was emplaced into the Sveconorwegian orogenic belt of southwest Scandinavia at 931±3 Ma. Emplacement took place at around 5.5 kbar producing a thermal aureole with osumilite and pigeonite isograds and evidence for dehydration melting. The early history of the hosting terrane most likely dates back to Gothian or late Pre-Gothian times and contain evidence for numerous episodes of folding and deformation. Contact metamorphism was superimposed on a crustal volume, which had been exposed to Sveconorwegian granulite facies metamorphism between 1024 and 970 Ma. Deformation patterns, mineral compositional considerations and geothermobarometry imply that the Rogaland anorthosites crystallized along a P-T trajectory starting at 10-13 kbar, and were emplaced in a mushy state. The possibility that primitive jotunites may be parental to the andesine anorthosites have recently been substantiated, and experimental data show that these jotunites most likely formed by melting of gabbronoritic sources in the lower crust. The 230 km2 Bjerkreim-Sokndal Layered Intrusion also derive from jotunitic parents, and jotunites form a continuous liquid line of descent filling the gap between basic and acidic rocks in Rogaland. This intrusion contains a >7000 m thick layered cumulate sequence, consisting of virtually all the rock types belonging to the anorthosite kindred. The intrusion morphology, layering and compositional variation result from a variety of magma chamber processes, which are discussed in detail. The Rogaland Anorthosite Province also hosts numerous Fe-Ti oxide deposits of variable size, grade and composition. The oxide deposits have been divided into three basic types based on their oxide-phosphate association; type 1: ilmenite-only, type 2: ilmenite + magnetite and type 3: ilmenite + magnetite + apatite. This excursion guide provides detailed itineraries to most parts of the Rogaland Anorthosite Province, with in-depth descriptions of more than 40 key localities, The itineraries cover the various anorthosites, the Bjerkreim-Sokndal Layered Intrusion, jotunitic and acidic intrusions, the hosting metamorphic complex, as well as Fe-Ti oxide and sulfide deposits.
