Les services publics de l’emploi ont délégué leur mission d’accompagnement des chômeurs aux prestataires de service. L’article s’intéresse au déroulement des collaborations entre services publics et opérateurs privés d’emploi, en Belgique et en Suisse. Ces partenariats sont confrontés à deux épreuves qui sont le recrutement des candidats dans les projets de formation et la mesure des résultats de la prestation. Notre hypothèse initiale soutient l’idée que les jeux d’acteurs ont plus d’effet dans la résolution des situations critiques que le cadre de collaboration. La comparaison internationale nous permet de faire varier les modalités de création des partenariats et de montrer une articulation particulière entre jeux d’acteurs et cadre de collaboration.

Background Previous studies have separately reported impaired functional, structural, and effective connectivity in patients with disorders of consciousness (DOC). The perturbational complexity index (PCI) is a transcranial magnetic stimulation (TMS) derived marker of effective connectivity. The global fractional anisotropy (FA) is a marker of structural integrity. Little is known about how these parameters are related to each other. Objective We aimed at testing the relationship between structural integrity and effective connectivity. Methods We assessed 23 patients with severe brain injury more than 4 weeks post-onset, leading to DOC or locked-in syndrome, and 14 healthy subjects. We calculated PCI using repeated single pulse TMS coupled with high-density electroencephalography, and used it as a surrogate of effective connectivity. Structural integrity was measured using the global FA, derived from diffusion weighted imaging. We used linear regression modelling to test our hypothesis, and computed the correlation between PCI and FA in different groups. Results Global FA could predict 74% of PCI variance in the whole sample and 56% in the patients' group. No other predictors (age, gender, time since onset, behavioural score) improved the models. FA and PCI were correlated in the whole population (r = 0.86, p < 0.0001), the patients, and the healthy subjects subgroups. Conclusion We here demonstrated that effective connectivity correlates with structural integrity in brain-injured patients. Increased structural damage level decreases effective connectivity, which could prevent the emergence of consciousness. [less ▲]

The public employment services have contracted out their jobseeker guidance role to service providers. The paper focuses on how the collaboration between the public services and private employment operators is organised in Belgium and Switzerland. These partnerships have to contend with two challenges, which are the recruitment of candidates for training projects and the measurement of the results of the service. Our initial hypothesis supports the idea that stakeholder games are more effective in solving critical situations than the collaborative framework. The international comparison allows us to vary the partnership creation methods and to show a particular articulation between the stakeholder games and collaborative framework. [less ▲]

Single-family houses are a common form of housing in Europe. Most were built in the context of the suburbanization after World War II and are now facing challenges arising from generational changes as well as increasing living and energy standards (Fina, Planinsek and Zakrzewski, 2009). According to the hypothesis of this paper, in several EU regions, single-family houses may face future challenges arising from oversupply and lack of adaptation to current demand. To examine this, the paper analyses the present situation and discusses the prognosis for the challenges described above regarding the three neighbouring north-western European countries Belgium, Germany, and the Netherlands, based on available data and a review of country-specific characteristics of housing markets as well as national policies. Despite an impending mismatch between demand and supply, planning policies still support the emergence of new single-family houses. The comparison of Belgium, Germany, and the Netherlands shows the growing polarization between shrinking and growing regions and central and peripheral sites apparent at different stages in the three countries. While a high rate of vacancies is already registered for some regions in Germany (Effenberger, 2015), in the Netherlands this phenomenon can only be seen near the borders and in villages within the Randstadt conurbation (Hospers et al., 2015). In Belgium also, this phenomenon is not yet widespread, but in some suburban neighbourhoods dating from the 1950’s and 1960’s more and more single-family houses are becoming more difficult to sell, indicating an emerging mismatch between supply and demand (Chambre des Notaires de la Province de Liège, 2015). This article proposes some instruments which enable municipalities to intervene in single family housing neighbourhoods which are largely dominated by private ownership. These instruments are not yet widely established in single-family housing neighbourhoods but that may become important in the future [less ▲]

BACKGROUND: Adequate motor control is considered important for spinal stability and the prevention of low back pain in adulthood and in childhood. OBJECTIVE: Given that the sitting position can affect proprioception, this study aimed to evaluate the influence of using at school a triangular and dynamic cushion on schoolchildren’s trunk motor control. METHODS: Thirty 8-year-old schoolchildren were randomized into a control group (n=15) and a “cushion group” (n=15), in which the children used the cushion for one year and a half. At the end of this period, a 3D-analysis was used to assess lumbar spine proprioception by means of a trunk repositioning task performed blindfolded in a seated position in two conditions (on a stable and on an unstable surface). RESULTS: The schoolchildren in the cushion group performed better at the trunk repositioning task (p=0.02) and hold their lumbar lordosis (p=0.03) better than the control children, in both conditions (stable and unstable). CONCLUSIONS: This preliminary study suggests that daily use of a triangular dynamic cushion has a beneficial impact on children’s lumbar proprioception. Further studies are needed to confirm these results and investigate the effectiveness of its use to prevent low back pain in adulthood. [less ▲]

Based on the case study of Jeanne, the objective of this article is to study patterns of anorexic people’s specific subjectivity. We seek to identify, in a first-person perspective, the core vulnerability features of anorexic existence, beyond the dimension of food alone. The identification of a psychopathological structure results in a better understanding of Jeanne’s clinical situation and helps formulate psychotherapeutic and prophylactic recommendations. We suggest that so-called “denial” is a psychological mechanism that should be reconsidered. Denial is not a mechanism pertaining to anorexic subjects alone, but is also a process encountered both in the patient’s family and in the therapeutic environment. Anorexic denial is based on anosognosia and the refusal to see one’s own thinness, while other people’s denial consists in a widespread inability to perceive the altruism and intersubjective problematic on which the existence of an anorexic subject fundamentally depends.

Based on the analysis of a clinical case, namely a borderline patient displaying several self-realised tattoos, we’ll broach three principal characteristics of borderline existence. They are instantaneity, ubiquity and a sense of disappearing-body. Given this original understanding of the trouble, the issue of tattoo practice in borderline people, as well as the very particular relationship they maintain with their own body and other people, will be discussed. We’ll also highlight the dialectics between the objectification of the body, as an object which is likely to be manipulated and modified, and the objectivation of the body, as an object dotted with the special and determining power of being animated by a subjectivity. We’ll end by emphasising how the borderline personality find its place and is, in a way, in tune with the postmodern evolution of our current society. [less ▲]

Quasars are one of the most peculiar types of objects in astronomy. The supermassive black hole these harbour effectively makes the surrounding matter radiates an enormous amount of energy before getting in the vicinity of the black hole horizon out of which it will never escape. This ironically leads to the most luminous phenomenon in the Universe while being non-transient. It is hence quite natural to rely on these cosmic headlights, visible up to ages when the Universe was still very young, so as to achieve some of the currently most important cosmological applications, notably regarding the determination of the cosmological parameters $H_0$, $\Omega_\Lambda$ and $\Omega_m$. The Gaia mission, on its side, is one of a kind given the one billion of celestial objects it is intended to observe, among which more than half a million quasars are expected. Furthermore, owing to its exceptional astrometric precision, Gaia stands out to be extremely well suited for the detection of gravitational lens (GL) systems. In the latter, light rays coming from a distant background quasar are deflected by the presence of a massive galaxy being in the line-of-sight that leads to the production of multiple images of this background quasar upon a favourable alignment between the quasar, the galaxy and the observer. Supplemental constraints on the aforementioned cosmological parameters being then gained based on these GLs. Gaia hence provides an unprecedented opportunity to detect and characterize quasars as well as to identify GLs which ultimately bring a better understanding of the Universe we live in. This thesis is accordingly concerned with the development of software solutions dedicated to the determination of the astrophysical parameters (APs) of the quasars that Gaia will observe, on one hand, and to the recognition of the GLs among the billion of sources it will uncover, on the other hand. Although Gaia provides state-of-the-art astrometric and photometric observations, its capability in characterizing these celestial objects remains however restricted by the relatively low spectral resolution of the blue and red spectrophotometers upon which it is based as well as by the limited signal-to-noise ratio that is associated with faint objects, including quasars. In addition, the overwhelming amount of data that Gaia has to process translates into a stringent need for algorithms having both low numerical complexities as well as low memory usages. These restrictions and shortcomings along with the requirement for reliable APs were at the heart of this research that led to the development of two specifically designed methods that are the weighted principal components analysis and the weighted phase correlation method. The former of these methods allowed us to extract the most significant patterns out of quasars with a view of using these in the production of a spectral library of quasars as observed by Gaia. These were subsequently used in a fast and automated procedure designed to guess the redshift of the quasars within the Gaia mission through the latter mentioned method. Other APs that are the slope of the quasar continua, the total equivalent width of their emission lines and whether these encompass broad absorption lines or not, being then concurrently derived based on the results of these methods. Finally, the identification of GL candidates relies on the recognition of the structures and symmetries that are observed within lensed images through supervised learning methods. The specific method we choose to use, based on extremely randomized trees, was shown to yield a low contamination rate on simulated configurations composed of three images as well as a very high probability of detection in cases of four image configurations. Real observations out of the first Gaia data release were processed and resulted in the identification of candidates having three potentially lensed images which are currently waiting for confirmation using ground-based facilities.

This paper explores the entanglement between social status and the bestowal of heroic honours upon deceased political leaders and elite members in the late-classical and early Hellenistic period. Epigraphic and literary sources shedding light on the establishment, justification and social impact of heroic honours practised by different social groups will be discussed, to investigate the implications of the social status of cult agents and recipients upon the definition of the position of honoured humans in relation to the superhuman sphere. This will also imply exploring the types of relationships existing between private heroic foundations and royal divine foundations in the studied period. Contrary to a generally accepted assumption, it will be argued that heroization was common for members of elite families, while it was not the primary option to reward local political leaders, since their honours were principally modelled after godlike honours. For instance, when they came into existence during the mid-Hellenistic period, cults for high-ranking civic leaders were largely modelled on godlike honours for monarchs, but were decreed after death – it will be argued – to preserve a hierarchical distinction between the social status of their recipients. The posthumous bestowal explains why honours for great civic benefactors also drew on typically heroic honours, such as public burial inside the city. However, similar contaminations of heroic and divine honours had already been exploited for the worshipped deceased kings of the early Hellenistic period (e.g. Alexander at Alexandria, Demetrius at Demetrias), so that a certain mixture of divine and heroic features could be said to have been directly transferred from royal to non-royal leaders. In neither case, however, did the presence of heroic features imply that cultic honours for Hellenistic political leaders would be commonly labelled as heroic. A revealing case is that of the Hellenistic leader Aratus, whose “fitting honours” decreed at Sicyon (Polyb. 8.12-7-8; Plut., Arat. 53) are labelled as heroic by moderns only because they were decreed posthumously. Similarly, at Megalopolis, the posthumous honours for the commander Philopoimen comprised a public tomb in the agora – a typically heroic honour – but were labelled as “honours equal to the gods”, not as heroic. We must wait for the late-Hellenistic and Imperial period to trace a significant multiplication of honours for political leaders explicitly labelled heroic. [less ▲]

Grassland carbon budgets are known to be greatly dependent on management. In particular, grazing is known to directly affect CO2 exchange through consumption by plants, cattle respiration, natural fertilisation through excreta, and soil compaction. This study investigates the impact of two grazing methods on the net ecosystem exchange (NEE) dynamics and carbon balance, by measuring CO2 fluxes using eddy covariance in two adjacent pastures located in southern Belgium during a complete grazing season. Rotational (RG) grazing consists of an alternation of rest periods and short high stock density grazing periods. Continuous grazing (CG) consists of uninterrupted grazing with variable stocking rates. To our knowledge, this is the first study to assess the impact of these grazing methods on total net ecosystem exchange and CO2 exchange dynamics using eddy covariance. The results showed that NEE dynamics were greatly impacted by the grazing method. Following grazing events on the RG parcel, net CO2 uptake on the RG parcel was reduced compared to the CG parcel. During the following rest periods, this phenomenon progressively shifted towards a higher assimilation for the RG treatment. This behaviour was attributed to sharp biomass changes in the RG treatment and therefore sharp changes in plant photosynthetic capacity. We found that differences in gross primary productivity at high radiation were strongly correlated to differences in standing biomass. In terms of carbon budgets, no significant difference was observed between the two treatments, neither in cumulative NEE, or in terms of estimated biomass production. The results of our study suggest that we should not expect major benefits in terms of CO2 uptake from rotational grazing management when compared to continuous grazing management in intensively managed temperate pastures.

A travers une sélection de sources littéraires grecques et latines, datant de l’époque d’Alexandre jusqu’à la haute période impériale, on se propose de discuter quelques aspects de la thématique concernant l’existence (ou l’absence) de règles morales auxquelles la conduite des souverains devrait être sujette par rapport à la consommation de la nourriture et du vin. Plutôt que de prendre en considération l’aspect médical de la diète royale, l’étude se focalise sur ses implications sociales et symboliques : notamment, le rôle de la consommation sociale de la nourriture dans la définition d’une royauté qui accepte d’obéir à des règles partagées de modération et d’autocontrôle, promues et protégés par les élites, ou qui, par contre, prétend de manifester sa dimension charismatique à travers une conduite se plaçant consciemment au-delà des limites imposées aux sujets. Les textes analysés discutent le thème du rapport entre le souverain et la nourriture soit à travers les récits de banquets devenus célèbres dans la tradition historiographique et rhétorique, soit par le biais de scènes mythiques ou de banquets historiques imaginaires, où la fiction littéraire sert à thématiser le rapport entre le souverain et les élites ainsi que la mise en place d’une hiérarchie de cour. Un aspect crucial de cette analyse concerne l’identification des classes sociales appelées, dans les textes, à définir les règles du rapport entre le roi et la nourriture, ainsi qu’à exercer le rôle de contrôleurs du respect de ces règles. Un autre aspect à considérer est l’appartenance sociale des auteurs des textes qui prescrivent, approuvent ou stigmatisent certaines pratiques. Considérées ensemble, ces deux perspectives nous permettront de discuter les intérêts et l’agenda des groupes qui s’expriment à travers ces textes. Une attention particulière sera donnée à l’époque de transition entre la fin de la période hellénistique et le début du Principat, lorsque la réflexion sur la sobriété ou la tryphè (ou, selon une perspective critique, la débauche) du roi s’inscrit dans une discussion plus large sur le choix de continuité ou de rupture entre le modèle royal hellénistique et le type de pouvoir monarchique universel expérimenté par les premiers empereurs.

Adaptive facades are performance based envelopes that are able to respond dynamically to climatic conditions. One of the recognized adaptive façade technologies is electrochromic glazing. However, very few studies evaluated the performance of electrochromic glazing on the building level. Therefore, we selected a case study of a certified educational building with a nearly zero energy building performance that includes an electrochromic facade. The overall aim of the research is to understand the performance requirements of electrochromic glazing and its overall contribution to energy saving s and thermal and visual comfort improvement. The performance of the Swiss International School in Dubai was analyzed based on interviews with the design and build team, monitored data and post occupancy evaluation. A systematic process mapping took place to review the performance indicators, simulation tools and team responsibilities during the design, construction and operation stages of the building. The paper identifies the key performance criteria of electrochromic glazing in relation to energy and comfort. Finally, we assess the significance of using electrochromic glazing from a technical point of view and share the learned lessons for architects and facade engineers [less ▲]

Adaptive facades can ensure step-change progresses in the energy efficiency and the use of renewable energy while improving the comfort of the occupants. Therefore, the purpose of this structured interview is to assess advantages, disadvantages and future expectations considering the adaptive facades. This work is a part of actions of The COST Action TU1403 Adaptive Façade Network. The objective of this report is to gain an understanding of how experts currently define adaptive façade systems, which simulation tools they use, the major strengths, weaknesses, opportunities and treats of adaptive façade systems, key performance indicators they use and their vision for the future of adaptive facades. With this information gathered, it is anticipated that adaptive façade professionals will carry on assessment of adaptive facades. A qualitative study design was employed, using semi-structured interviews. Interviewees working in academia and practice were selected. The interviewees represented the range of possible adaptive facade professionals, from researchers and designers considered optimization in the assessment of adaptive facades. Also, every interviewed expert was asked to approve their responses and add any additional comment to their answers. [less ▲]

Following a brief overview and recapitulation of the ‘more Europe’ developments having taken shape in the wake of crisis, the chapter will proceed in summarising how Member States’ interests have been embedded directly within the post-crisis EU regulation framework. It will be submitted that two different and complementary kinds of ‘interest inclusion’ techniques can be distilled, more or less explicitly, within the newly created financial market supervision frameworks. The inclusion and presumed safeguarding of Member States’ interests by virtue of administrative law tools is not entirely unproblematic.
