Cette contribution s’intéresse à la mise en oeuvre de l’accompagnement des demandeurs d’emploi, en tant que politique sociale visant la (ré)insertion socioprofessionnelle des personnes éloignées de l’emploi par une lutte contre le chômage de longue durée et l’exclusion sociale. Plus précisément, elle porte un intérêt singulier aux relations de pouvoir qui s’exercent, dans les échanges et les interactions, entre les intermédiaires privés du marché du travail et leurs usagers, dès la phase de sélection des projets d’accompagnement. Cette contribution s’attèle dès lors à rendre compte des formes de contrôle qu’exercent les intermédiaires privés dans la concrétisation de leur action d’insertion lorsqu’ils sont contraints de respecter les orientations européennes en matière de profilage. Elle repose, par conséquent, sur l’analyse des ressorts et des effets de pouvoir en considérant l’influence de pressions institutionnelles induites par le contexte de rationalisation et d’efficacité à l’intérieur duquel la prise en charge des demandeurs d’emploi est réalisée.Ce faisant, cette contribution s’attache à illustrer l’influence de l’action d’intermédiation exercée sur les transitions des demandeurs d’emploi par la présence de deux effets de trappe, étayés par l’activation de mécanismes de filtrage à différents moments de l’accompagnement. Par ce biais, elle vise à rendre compte de la logique structurelle qui oriente les transitions professionnelles des usagers vers une forme de « précariat social » sur le marché du travail. Elle s’appuie, pour ce faire, sur une recherche empirique de nature qualitative, menée entre septembre 2013 et juin 2015, en Belgique Francophone, auprès de six structures privées spécialisées dans l’accompagnement vers et dans l’emploi.

Cette contribution porte un intérêt singulier aux enjeux relatifs à l’externalisation de l’accompagnement des demandeurs d’emploi, en tant que mesure d’activation, auprès d’organismes privés d’insertion socioprofessionnelle en Belgique francophone. Plus précisément, elle s’intéresse à l’influence de dispositifs techniques dans la concrétisation de leur mission de réinsertion. Pour ce faire, elle porte une attention particulière à l’analyse des relations de pouvoir qui s’exercent, à distance, entre les services publics de l’emploi et les prestataires privés, par le biais de technologies afin de coordonner et de contrôler l’activité déléguée. Elle s’attache, dès lors, à rendre compte des différentes formes de pression institutionnelle qui émanent de ces technologies, à différentes phases de l’accompagnement, sous-tendant un mouvement de standardisation de l’action publique. Par ce biais, cette contribution démontre à quel point la standardisation et les indicateurs chiffrés deviennent de véritables outils de pouvoir destinés à évaluer tant la performance des opérateurs privés que l’efficacité de leur action. Par ce gouvernement par les instruments, les organismes privés sont à présent confrontés à un nouveau modèle de gouvernance qu’il convient de s’approprier et/ou de contourner. Partant de ces constats, notre raisonnement sera guidé autour de deux questions : quel est l’effet de ces dispositifs techniques dans le travail quotidien d’accompagnement des opérateurs privés ? Et de quelle marge de manoeuvre disposent-ils pour se les réapproprier et contourner les contraintes qui en résultent ? De la sorte, cette contribution s’inscrit dans une approche analytique qui s’attache à rendre compte des jeux de pouvoir en présence, en appréhendant l’accompagnement au concret, saisi dans ses actions de suivi et d’opérationnalisation.

In this lecture, an approach based on principal component analysis (PCA) is considered for three purposes, namely damage detection, structural health monitoring and identification of nonlinear parameters in structural dynamics. The key idea of PCA is to reduce a large number of measured data to a much smaller number of uncorrelated variables while retaining as much as possible of the variation in the original data. The first problem to which PCA is applied here is the damage detection problem. When applied to vibration measurements, it can be shown that the basis of eigenvectors (called the proper orthogonal modes) span the same subspace as the mode-shape vectors of the monitored structure. Thus the damage detection problem may be solved using the concept of subspace angle between a reference subspace spanned by the eigenvectors of the initial (undamaged) structure and the subspace spanned by the eigenvectors of the current (possibly damaged) structure. The second problem concerns structural health monitoring of civil engineering structures when environmental effects (e.g. the influence of the variation of the ambient temperature) have to be removed from the structural changes. In this case, PCA may be applied on identified modal features (e.g. the natural frequencies) to separate the changes due to environmental variations from the changes due to damage sources. The third problem is related to the estimation of nonlinear parameters using model updating techniques. In this case, the most interesting property of PCA is that it minimizes the average squared distance between the original signal and its reduced linear representation. When applied to nonlinear problems, PCA gives the optimal approximating linear manifold in the configuration space represented by the data. The linear nature of the method is appealing because the theory of linear operators is still available. However, it should be borne in mind that it also exhibits its major limitation when the data lie on a nonlinear manifold. [less ▲]

Introduction With the stop jump, the counter movement jump (CMJ) is probably the most used jump in sport. In the literature, a number of studies use the counter movement jump to explore (neuro-)muscular fatigability [1-4]. However, due to the continuous [1-3] (or semi-continuous [4]) character of the test, the CMJ become drop jumps from the second one. Nevertheless, the drop jump isn't the most frequent jump type in sport. These evaluations, with (semi-)continuous jumps, don't reflect the sport reality and therefore a more effective (neuro-)muscular jumping fatigability evaluation must be validated. Methods Nineteen volleyball players (23,5 ± 3,3 years, 187,6 ± 6,6 cm, 77,5 ± 8,5 kg), with no history of (major) lower limb injury, submitted to two jumping fatigability tests, with seven days between each session, under the direction of a single researcher. The jumping fatigability tests consists of the repetition of 50 maximal CMJ at the rate of 33bpm. Between each CMJ, the subject were asked to make a full triple-extension and to wait the next auditory and visual signal of the metronome to start the hip-knee-ankle flexion. With these instructions, each jump remains a CMJ. Subjects were asked to leap as high as possible from the first to the last CMJ. The jumping height was recorder for each jump with three dimensional camera. The reproducibility was assessed by Standard Error of Measurement (SEM), Minimal Difference needed to be considered real (MD), Coefficient of Variation (CV), Pearson Correlation Coefficient (PCC) with 95% confidence interval, Effect Size Cohen (ES Cohen) with 90% confidence interval, paired Student's t-test, Intraclass Correlation Coefficient (ICC 2,1) with 95% confidence interval and Magnitude-Based Inferences (MBI). Results The results summary is available in the Table 1. In this table, only few parameters are presented and only for the partial sums of the first 10, 20, 25, 30, 40 and 50 jumps. Our analyses were based on the partial sums per interval of one jump and all statistical tests listed in "Methods" section have been considered. The partial sum with twenty-five CMJ have an excellent reproducibility (MBI with 0/99/1; ICC with 0.961 [0.902/0.985]; ES Cohen with -0.03 [-0.17/0.10]; PCC with 0.966 [0.911/0,987] and p-value < 0.0001). Moreover, it induce a great height decrease (-23%) and its duration (45.5 s) is similar to the recommendation for the knee fatigability isokinetic protocol [5]. MBI (+/trivial/-) Height decrease ICC (2,1) Test duration 10 0/100/0 -12,7% 0.967 18 s 20 0/99/1 -19,0% 0.964 36 s 25 0/99/1 -23,0% 0.961 46 s 30 0/98/1 -25,6% 0.955 55 s 40 0/98/1 -32,1% 0.950 73 s 50 0/98/2 -38,4% 0.943 91 s Table 1: reproducibility statistics results depending on the number of jumps considered (magnitude-based inferences (MBI) with percentage chances of better/trivial/worst retest vs test results; height jump decrease (last jump / better jump); ICC (2,1); test duration). Discussion Because of the (semi-)continuous character of a majority of fatigability jumping test [1-4], our test is the first, at our knowledge, to explore the reproducibility of a strict CMJ jumping fatigability task. Considering the statistical (relative and absolute) reproducibility results, twenty-five maximal CMJ seems to be the best compromise between reliability of the data and physiological interpretability of test's results. Indeed, its (relative and absolute) reproducibility is excellent and it induces a greater height decrease than shorter test while remaining similar in total duration than other fatigability tests which explore the anaerobic lactic system.

Simultaneously to the ESA Rosetta mission, a world-wide ground-based campaign provided measurements of the large scale activity of comet 67P/Churyumov-Gerasimenko through measurement of optically active gas species and imaging of the overall dust coma. We present more than 2 yr of observations performed with the FORS2 low-resolution spectrograph at the VLT, TRAPPIST and ACAM at the WHT. We focus on the evolution of the CN production as a tracer of the comet activity. We find that it is asymmetric with respect to perihelion and different from that of the dust. The CN emission is detected for the first time at 1.34 au pre-perihelion and production rates then increase steeply to peak about 2 weeks after perihelion at (1.00 ± 0.10) × 10[SUP]25[/SUP] molecules s[SUP]-1[/SUP], while the post-perihelion decrease is more shallow. The evolution of the comet activity is strongly influenced by seasonal effects with enhanced CN production when the Southern hemisphere is illuminated. [less ▲]

This report describes the treatments and discusses the cost effectiveness of a Negative Pressure Wound Therapy (NPWT) device on a gangrenous mastitis case. Mastitis is an inflammation of the mammary gland found mainly in lactating females. Coliforms (Escherichia coli), Staphylococcus spp (Staphylococcus aureus) and, to a lesser extent, Streptococcus spp are the most commonly isolated organisms in bitches. The bitch can be presented because of local signs of inflammation, puppies failing to thrive or even severe septic shock. While more common in ruminants, gangrenous mastitis is rare in the bitch. It is mostly due to Staphylococcus aureus, a gram positive and catalase positive bacteria producing alpha hemolysin. This toxin binds to ADAM10, a transmembrane protein, forming pores in the cell membrane, causing an acute inflammation via intracellular calcium flow, leading to severe oedema, necrosis and gangrene. Loss of skin integrity also comes from the cleavage of E-cadherin by ADAM10 after its toxin-mediated activation. A 8.7kg, 3-year-old neutered female Sheltie farm dog was referred to the Veterinary Clinic of the University of Liège for suspicion of septic peritonitis after an ovariohysterectomy on 4 dead puppies 36 hours earlier. They died during long lasting dystocia. Amoxicillin-acid clavulanic and enrofloxacin antibiotherapy had been initiated during surgery. The dog was in decompensated septic shock. The surgical wound was not reactive and no sign of peritonitis was seen by abdominal ultrasonography. The right inguinal and the two most caudal left mammary glands were swollen, crackling with a patchy blue discoloration. An acute fulminant mastitis with gangrenous involvement and sepsis was diagnosed. Fluids and continuous rate infusion of norepinephrine and dobutamine were administered to control severe hypotension. Metronidazole was added since Clostridium spp could not be excluded. Debridement was started as soon as the arterial pressure was stabilised and the wound was disinfected with hydrogen peroxyde for the 3 first days. While hydrogen peroxyde is indicated for catalase negative infections, the already started antibiotherapy prevented bacterial identification and sensitivity determination. Alginate-honey patches replaced wet to dry bandages after 4 days. After 7 days of progressive debridement, the wound was 15cm long, 13cm wide and 1.2cm deep. A NPWT device was placed under anaesthesia after extensive debridement. It was kept in place for one week with one renewal after 2 days under slight sedation. The wound was then surgically closed. Cutaneous sutures were removed 10 days later as cicatrization was satisfactory. NPWT is indicated in open wound management, for infection control and for stimulating granulation tissue production prior to reconstruction. It increases contraction in deep, three dimensional wounds. Closure rate is significantly shorter with NPWT than with standard wet to dry bandages. Cost of NPWT is comparable to standard bandages but more comfortable for the patient. Standards bandages require daily changes, sometimes for several weeks and under repeated anaesthesias, which may be debilitating for the patient and expensive for the owner. Conversely, NPWT is changed only once and allows earlier surgical closure of the wound. The main complication is vacuum loss, which is surgeon’s experience dependant. [less ▲]

For human-robot cooperation, intrinsic safety approaches aim at reducing the energy involved in the motion of the robotic system and at increasing the system compliance in order to reduce the risk of injury in case of an unexpected collision. Robots based on lightweight and inherently exible links exhibit attractive features in this context but the control of their motion then leads to a tremendous challenge. This paper presents a novel trajectory planning method for 3D robots which aims at improving the tracking accuracy despite the link exibility. [less ▲]

Additive manufacturing is more and more used in the field of industry. This technique is notably employed in investment casting process in order to build cores and models. Nevertheless investment casting remains not cost effective in case of prototypes and very small series due to the quite large amount time needed to build and dry the molds. Additive manufacturing may also be used to directly shape metal parts but several problems are still linked to this technique as the presence of local defects in parts and the limitation of the number of metal or alloy available for this technique on the market. We propose an intermediate method that permits to build directly molds and cores by additive manufacturing using equipment initially dedicated to build metal parts. This method presents the main advantage to cast with a large variety of metals or alloys using a single ceramic material and only one set of building conditions. The properties of the casted parts are very similar with those produced by investment casting. This technique also permits the unique advantage to control the design of the shell thickness and structure in order to have a better control of the thermal fluxes during metal cooling. This would potentially ensure a better control of some casting defects. The use of alumina processed by selective laser melting (SLM) is shown and its outstanding resistance to temperature differential is demonstrated through casting trials with two diffferent representative alloys. Casting trials in industrial conditions will be illustrated. [less ▲]

Using data mining methods, this paper presents a new means of identifying freshmen's profiles likely to face major difficulties to complete their first academic year. We aim at early detection of potential failure using student data available at registration, i.e. school records and environmental factors, with a view to timely and efficient remediation and/or study reorientation. We adapt three data mining methods, namely random forest, logistic regression and artificial neural network algorithms. We design algorithms to increase the accuracy of the prediction when some classes are of major interest. These algorithms are context independent and can be used in different fields. They rely on a dynamic split of the observations into subclasses during the training process, so as to maximize an accuracy criterion. Four classes are so built: high risk of failure, risk of failure, expected success or high probability of success. Real data pertaining to undergraduates at the University of Liège (Belgium), illustrates our methodology. With our approach, we are now able to identify with a high rate of confidence (90%) a subset of 12.2% of students facing a very high risk of failure, almost the quadruple of those identified with a non-dynamic approach. By testing some confidence levels, our approach makes it possible to rank the students by levels of risk and a sensitivity analysis allows us to find out why some students are likely to encounter difficulties.

Introduction The Belgian Foundation against Cancer proposes an adapted physical activity (APA) program for cancer patients and survivors, called Raviva (http://www.cancer.be/raviva-bouger-pour-se-sentir-mieux).The activities are supervised by instructors with inconstant trainings and experiences. Contrary to other countries, Belgian APA instructors do not necessarily need to follow specific education programs such those proposed by the ACSM (Schmitz et al., 2010) or other organizations that propose exercise guidelines for cancer survivors. The aim of this study was to identify good practices in APA for cancer patients and survivors concerning activity characteristics and instructors behaviors, from the point of view of the Raviva program participants. Methods Firstly, an online questionnaire was submitted to Raviva participants; 72 of them filled it in. Secondly, 3 video-stimulated recall interviews were conducted after 3 different Raviva sessions (fitness, yoga and aqua-aerobics), each time with another participant. Results and discussion The sessions characteristics that participants like the most are related to the choice and quality of the proposed exercises (22% of responses) and to the perceived benefits of the activities (20%). The most appreciated qualities for an instructor are related to his/her human qualities (43%) and his/her expertise (32%). What participants like least about the sessions is a poor organization (27%) and what they like least about the instructors is linked to bad choices of exercises (18%). The video-stimulated recall interviews confirmed these data and provided more precision. Finally, we noticed that differences in responses were observed depending on the type of activity participants took part in. These findings could help instructors adapt their practices to their participants’ needs in order to promote adherence to physical activity among this population. References Schmitz, K.

Road remains the most used mode in Europe. Even if it is appreciated for its responsiveness, flexibility, and quickness, road transport is however responsible for negative impacts on its environment like air pollution or climate change. Intermodal freight transport i.e. the transportation of goods using two or more modes of transport, in the same loading unit, without handling of the goods themselves is identified by the European Commission as an interesting solution for limiting the negative impacts of transport. In the classical conception of intermodal transport, pre- and post-haulage travels are supposed to be short, and to be performed by road transport, whereas the long-haul travel is done using rail or inland waterways (IWW). The objective of this study is to determine the impact on intermodal attractiveness of allowing other combinations of modes than the classical road-rail/IWW-road combination, during an intermodal travel. The goal is to determine the flow distribution of goods between direct transportation by road, rail or IWW, and any combination of these modes using intermodal transport. The novelty consists in taking into account three modes of transport in a mixed integer programming model, and to allow the transfer from any mode to any other at intermodal terminals where these modes coexist. For testing the hypothesis of intermodal transport attractiveness on medium to long distance, the model is applied to experimental data at the European level. [less ▲]

This contribution explores how actors redefine infrastructures through an analysis of a project of “modernisation” in the making. Nowadays several companies undertake serious reflexions about their work environments, tools and practices according to the “Bricks”, “Bytes” and “Behaviours” motto (De Leede, 2017). Relying on digital solutions they aim to enhance more flexible work practices in time and space. For that purpose various strategic and operational actors contribute actively to foreseeing the future of both facility, technological and social infrastructures. By means of adjustment mechanisms such as coordination meetings and alignment speeches, the actors take various actions in order to ensure the continuity of the organisation; they perform what Ribes and Finholt named the “Long Now”, an ongoing work to generate a “sustainable future” (2009, p. 377). Our interest lies in exploring simultaneously the incremental deconstruction of the existing infrastructures and the progressive construction of the forthcoming work environment. This innovation process may be seized by studying successive waves of problematisation using the actor-network theory. In the perspective of the ANT, an organisation is always a precarious agency made of both people and artefacts (Latour, 2005). Material issues, technological opportunities and constraints as well as power games emerge through the analysis of “controversies” which make parts of the infrastructures noticeable and subject to discussion and negotiation. Those controversies evolve through time, revealing various “range of visibilities” of people and things at different times in the process (Larkin, 2013, p. 336). Our research shows how actors simultaneously make sense of the existing infrastructure while enacting its future developments. We point out how the actors themselves perceive, describe and draw on the infrastructure in order to make sense of the strategic objectives, to conduct the change project and to maintain their institution. We shed light on the process of redefining and reshaping the infrastructure itself through controversies and adjustments. [less ▲]
