: Suite aux récents bouleversements économiques et sociaux touchant les pays de l’Union Européenne, de nombreux partenariats entre services publics d’emploi et agences d’emploi privées se sont développés et complexifiés, suivant une logique de gestion mixte du marché de l’emploi. Cette communication porte sur l’étude d’un partenariat public-privé entre un service public régional belge et un organisme de formation. À partir des apports conceptuels et théoriques de la sociologie de l’action publique et de la littérature propre aux agences d’emploi privées et aux partenariats public-privé, nous analyserons la capacité d’un dispositif public à assurer la remise à l’emploi de son public-cible. Pour ce faire, nous étudierons son rôle et ses effets sur les trajectoires professionnelles des demandeurs d’emploi y recourant. [less ▲]

Au cours de ces dernières années, le souci d’allier flexibilité et sécurité au travail a conduit à l’essor considérable des métiers de l’intermédiation (Orianne et Maroy, 2008). En particulier dans le domaine de l’accompagnement et du développement de carrière, divers dispositifs privés d’aide et de suivi ont vu le jour afin de contribuer à l’amélioration des conditions de travail et d’assister les travailleurs dans leurs transitions professionnelles. Par leur action, ces nouveaux dispositifs n’hésitent pas à complexifier les temporalités sociales en créant de nouvelles opportunités d’emploi et en redéfinissant les rythmes de carrière. À l’aide d’une étude de cas dans le secteur du recrutement belge, nous analyserons la capacité d’un processus de mise en emploi à remplir de tels objectifs dans un contexte de gestion mixte du marché du travail. Approchée d’une manière qualitative (entretiens semi-directifs et observations), nous étudierons l’apport de cette agence de placement au travers d’un cadre théorique qui intègre les concepts de dispositif (Foucault, 1977 ; Peeters et Charlier, 1999 ; Raffnsoe, 2008) et de réseaux sociaux (Grossetti 2005, 2008 et 2011). Nous montrerons qu’un plus de régir l’offre et la demande de travail, ce dispositif d’intermédiation, par son système de cooptation et son accompagnement de carrière, assure la fluidification du marché et sécurise la dynamique des transitions professionnelles.

Belgian rivers are fragmented by numerous obstacles which considerably limit the free access of fish to functional habitats. Fish-passes are major tools used to increase stream continuity and improve connectivity in the upstream direction. Using two modern multispecies fish-passes, this study aims to investigate multiyear abundance of holobiotic potamodromous fish and their seasonal movement patterns in relation with environmental factors. The fish passes were monitored continuously during 5 and 7 years and are located in two Belgian streams: the (19.3m³.s-1) and the Berwinne (1.9m³.s-1). Results revealed the presence of 20 different fish species, 14 species in the Berwinne and 19 species in the occurrence, salmonids and cyprinids species were predominant. A great interspecific and intraspecific variability in capture periodicity and in terms of stimulation by combination of factor environmental was observed. This study highlights the complexity and the omnipresence of holobiotic potamodromous fish movements at different life stages, in medium size river and brings new information on fish passes efficiency and use by these poorly known species.

From age 30 onwards, kidney function physiologically decreases although this deterioration cannot yet be called chronic kidney disease. The latter appears in those exposed to cardiovascular risk factors associated with inflammation and oxidative stress. A diffuse atherosclerosis then develops Patients with a decreased glomerular filtration rate, especially below the threshold of 45 ml/min, are characterised by a poor physical heath and by cognitive disorders, leading to frailty. In these conditions, a management strategy to reduce the increased risk of acute kidney injury should be outlined and the need for renal replacement therapy be considered. One must try to maintain the best possible quality of life, promoting in some situations a conservative approach. [less ▲]

Place attractiveness is an important property to consider when modelling the spatial behaviour of a serial offender. Small spatial units are privileged in the recent literature to study the crime concentration-urban backcloth relationship, with the drawback of focusing on a single city. However, the urban backcloth is also shaped by the inter-cities and city-hinterland relationships. Our objective is to model the concentration of sexual offences for entire Belgium, at the very precise scale of the statistical sector in order to take into account the role of the urban hierarchy. Methods: We analyse the ViCLAS data for Belgium between 2004 and 2011. Specifically, we study the relationship between the concentration of initial contact scenes and socio-economic characteristics and facilities of the statistical sector, using two spatial models. First, we computed a spatial lag zero-inflated model (ZINB) in order to evaluate the global predictive capacities of the model. Then, a Poisson geographically-weighted regression (GWR) was run to study the spatial heterogeneity for each of the explanatory variables. Results: The zero-inflated negative binomial model with spatial lag recovers the neighbourhood environmental quality, the concentration of economic and cultural activities, and drinking places as major significant factors (Mc Fadden’s pseudo-r² of 0.2). The Poisson geographically-weighted regression underestimates the crime concentrations but highlights the spatial heterogeneity [less ▲]

Saltwater contamination constitutes a serious problem in Saloumestuary, due to the intermittent and reverse tide flows of the Saloum River. This phenomenon is caused by the runoff deficit, which forces the advance of saltwater 60 km upstream, contaminating surface water and thus causing the degradation of biodiversity and large areas of agricultural soils in this region. The present study aims to evaluate the consequences of saltwater contamination in the last three decades in this estuary by assessing the land-cover dynamics. Thus, latter consists of tracking the landscape-changing process over time to identify land-cover transitions. These transitions are closely related to the ecosystem-setting condition and can be used to assess the combined impacts of both natural and human-induced phenomena over a given period of time. In this study, special attention was given to mangrove degradation and to temporal progression of the salty barren soils locally called ‘‘tan’’. The loss of mangrove areas to tan and the general increase in salty barren soil areas can reflect the increase in the level of salinization in the study area over the time period under consideration. To fulfill this objective, four Landsat satellite images from the same season in the years 1984, 1992, 1999, and 2010 were used to infer time series land-use and land-cover maps of the Saloumestuary area. In addition to satellite imagery, rainfall records were used to evaluate climatic variation in terms of high-to-low precipitation during the time span considered. Spectral analysis indicated that from 1984 to 2010, mangroves and savanna/ rain-fed agriculture are converted to ‘‘tan’’ (denuded and salty soils). In addition, these results showed that significant changes in land use/land cover occur within the whole estuary system and reflecting therefore environmental degradation, such as land desertification and salinization, and vegetation degradation which reflect the advanced of salinity [less ▲]

The existence of an endophenotype of autism spectrum condition (ASC) has been recently suggested by several commentators. It can be estimated by finding differences between controls and people with ASC that are also present when comparing controls and the unaffected siblings of ASC individuals. In this work, we used a multivariate methodology applied on magnetic resonance images to look for such differences. The proposed procedure consists of combining a searchlight approach and a support vector machine classifier to identify the differences between three groups of participants in pairwise comparisons: controls, people with ASC and their unaffected siblings. Then we compared those differences selecting spatially collocated as candidate endophenotypes of ASC. [less ▲]

Estimated subglottic pressure (ESGP) is part of the aerodynamic measurements included in the vocal profile. It is an indication of vocal effort and can guide the therapist in his clinical approach. We aim to examine the clinical interest of the ESGP by observing its values according to voice pathology, age, gender and sound pressure level. We also examine the relationships between PSGE, DSI and VHI. Method:The study includes 418 patients (M:118/W:300). Each patient’s file consists of VLS, acoustic, aerodynamic and perceptual measures. The ESGP was collected through the Phonatory Aerodynamic System Model 6600 (KayPentax). Patients produced 3 sequences of / ipipi / at low (IL), conversational (IC) and high (IH) intensity. Patients were grouped according to the ENT’s diagnosis. Results: Patients without vocal lesions (MTD) had a significantly lower ESGP compared to patients with nodules, polyps, inflammation, edema (IL, IC), cysts (IC) or scar (IC). Patients with vocal fold atrophy had a lower ESGP than those suffering from nodules and polyps at conversational and high intensity, but were not differentiated at low intensity. Amongst patients without lesions (MTD), a positive correlation appeared between ESGP and intensity; which was not the case for patients with lesions. At high intensity, men had a significantly higher ESGP than women. At low intensity, we noted a positive correlation between the VHI scores and ESGP levels. At low and conversational intensity, we observed a negative correlation between DSI and ESGP scores. Conclusion: This study highlights the importance of considering ESGP in the vocal profile. As expected, patients with vocal pathology produce high ESGP. However, the correlations between intensity and ESGP vary depending on the patient's pathology. In addition, ESPG values allow the clinician to distinguish MTD and healthy patients and thus could help the therapist in his clinical approach. [less ▲]

This paper presents experimental results of the full 3-axis force vector and 3-axis moment vector acting on a propeller, commonly used for a Vertical Take Off and Landing Micro Aerial Vehicle (VTOL MAV). Measurements were carried out in a wind tunnel using a high resolution 6-axis force/moment sensor embedded in a customized test rig at several wind speeds, propeller rotational speeds and angles of the propeller shaft with respect to the air stream. Results show strong moments acting on the propeller in forward flight and unstable conditions in descending flight. Power calculations reveal a decrease in power consumption during slow forward flight and how motor efficiency can be maximized. [less ▲]
