Belgium, like many European Countries, has a serious challenge in the housing sector. The Federal planning bureau estimates the increase of the population by one million inhabitants by 2030, which represent 600,000 additional family requiring accesses to new housing facilities. There is a significant housing shortage for individual, single parent families, seniors and students. Population ageing (mainly due to increase life expectancy) combined with a constant grow rate of individuals living in collective households, leads to a substantial increase of demand of collective households. Furthermore, the stringent European performance environmental regulations for the building sector require that by 2020, all new construction are zero or nearly zero energy, (equivalent to 15 kWh/m2/year), with 60% efficient on-site coverage by renewable energy. The shortage of vacant land and the increasing energy performance requirements is pushing the idea of urban densification and zero energy construction households. [less ▲]

Faire l’histoire de l’édition en Belgique à partir de l’apparition du livre imprimé soulève un certain nombre de problèmes en fait de délimitation du domaine et de construction de l’objet. Les plus évidents touchent aux avatars politiques et linguistiques que les territoires formant l’État belge ont connus du XVe siècle à la fin du XXe siècle. D’autres proviennent du rapport de force très inégal qui s’est établi, à partir de la première moitié du XIXe siècle, entre le système de production du livre en Wallonie et à Bruxelles et l’édition française, avec les effets que ce rapport y exercera durablement en termes d’identité culturelle et de rayonnement, de structures de production et de diffusion, mais aussi de créneaux privilégiés. Ces problèmes et d’autres encore – dont témoigne une historiographie volontiers cantonnée à « l’histoire du livre et de l’imprimerie » – méritent d’être réexaminés dans la perspective de la publication imminente d’une Histoire de l’édition en Belgique profilant, du XVe au XXIe siècle, ses principales lignes de faîte. Histoire de l’édition et de ses pratiques – non du livre et de ses techniques. Histoire de l’édition dans toute son extension et à différents niveaux – non de la seule édition littéraire ou lettrée. Histoire d’un espace des possibles ayant su, dans certains secteurs, tirer force et spécificité de contraintes puissamment subies. [less ▲]

Why ask a person to answer a problem item, when you a priori know they won’t be able to solve it? It is a waste of time and resources, and you won’t gain any new information; this is both inefficient and ineffective. In contrast, computerized adaptive testing (CAT) is based on the principle that more information can be gained when one tailors the test towards the level of the person being tested. Computational and statistical techniques from item response theory (IRT) and decision theory are combined to implement a test that can behave interactively during the test process and adapts towards the level of the person being tested.The implementation of such a CAT relies on an iterative sequential algorithm that searches the pool of available items (a so-called item bank) for the optimal item to administer based on the current estimate of the person’s level (and optional external constraints). The subsequent response on this item provides new information to update the person’s proficiency estimate. This selection-responding-updating process continues until specified stop criteria have been reached. The consequence of such an adaptive test administration is that you get an individualized tailored test that is more efficient and more effective. Because you have less of a mismatch between the level of the test and the level of the test taker, there is a lesser burden for the latter and a higher precision for the former, and this with fewer items than a traditional fixed item-set test format. Furthermore, because it is computerized and sequential, test performance can be continuously monitored and reported directly after test completion. Item response models come into play to ensure comparable scores of these individual tailored tests by putting them on the same measurement scale and to precalibrate,the psychometric parameters of the items that are part of the item bank on which the sequential iterative algorithm operates. The workshop intends to tackle issues encountered during the setup of a computerized adaptive test, starting from the design towards the actual delivery of a CAT. [less ▲]

L'approche du jeu vidéo, non sous l’angle de la technique ou de l'étude des joueurs, mais comme un ensemble de pratiques et de phénomènes culturels, donne lieu à un double mouvement : d'une part la reconnaissance d'une culture commune qui fait médiation et d'autre part la création d'écarts de différentes natures entre les acteurs, les discours et les esthétiques : écarts de légitimité entre des pratiques ludiques instituées et d’autres plus périphériques (sur lesquelles se centreront les présentes communications), écarts rhétoriques produits par les joueurs qui se réapproprient les œuvres vidéoludiques pour les détourner, écarts identitaires présents dans les discours des amateurs, qui se définissent par des stratégies de distinction (par rapport aux professionnels, aux artistes, etc.) et écarts posturaux, mobilisés par les différents acteurs de la presse vidéoludique afin de se singulariser – notamment pour permettre une existence économique. Cet ensemble de problématiques seront traitées au sein d’un panel de communications, à travers différentes perspectives disciplinaires : la rhétorique et la sémiotique, la sociologie de la littérature et l’analyse des réseaux, et l’approche communicationnelle inspirée des « cultural studies ».

Interface essentielle entre le joueur et l’univers vidéoludique, l'avatar soulève la question du rapport au corps dans le jeu vidéo. En effet, la fonction d’incarnation permise par l’avatar – et qui est soulignée par l’étymologie même du terme – ajoute à la relation entre le corps et l’esprit du joueur une dimension nouvelle : celle du corps virtuel, qui déploie sa matérialité propre au sein de l’univers fictionnel. Ce corps « autre », dont le joueur prend possession, constitue une des conditions de son « insertion » dans le monde virtuel. Fondée sur une approche communicationnelle et nourri d’un pan de la pensée phénoménologique (à travers, notamment, la Phénoménologie de la perception de Maurice Merleau-Ponty), cette intervention entend questionner la problématique du rapport au corps au sein de l’univers du jeu.

Notre exposé sur la féminisation se centre principalement sur l’acquisition de patterns féminins dans le cadre d’une prise en charge chez les personnes souffrant de dysphorie de genre. Nous discutons de la voix en tant qu’identité de genre et de l’importance pour certaines personnes d’être perçue comme femme. Féminiser la voix est un défi tant les contraintes anatomo- physiologiques peuvent mener la vie dure à nos techniques de prises en charge. La recherche s’attèle à enrichir nos outils techniques pour une rééducation efficace et satisfaisante. A la lumière de la littérature scientifique, nous faisons le point sur les traitements chirurgicaux et orthophoniques, et proposons une prise en charge en 9 étapes. Celle-ci aborde les points suivants:
 Geste vocal sain, soutien respiratoire, hauteur tonale, résonance, courbes intonatives, contrastes intonatifs, volume, débit, articulation, langage et comportements non verbaux. [less ▲]

Digital textbooks, their recent version, completely new in terms of form and presentation, have risen not only numerous economic or sociological, but also educational and pedagogical issues. Should the digital textbook replace the traditional, printed version? Or do we rather speak of a product altogether different, built on novel principles of subject matter exploitation and shaped according to a teaching philosophy that intensifies activism, interactivity, progression and creativity? We attempt to answer the two above mentioned questions by analyzing three FLE textbooks for A1 level learners. [less ▲]

This paper investigates whether conditional accounting conservatism has informational benefits to financial market participants. Using a large sample of French firms over the period 2001-2014, we report that accounting conservatism improves the firm information environment by providing verifiable information. We specifically document that increases in accounting conservatism are associated with more accurate analyst earnings forecasts, less dispersed forecasts and less volatility in forecast revisions. We also provide evidence that increases in firm accounting conservatism lead to subsequent increases in stock market liquidity, tested on the price impact dimension. Overall, our findings are in line with conservatism being useful to financial markets participants such as financial analysts and investors. [less ▲]

A current research topic, that is developed in this presentation, is the study of disturbance of circadian hormonal cycles and the secretion of melatonin. Traumatic brain injury is associated to hypopituitarism in up to 10-35% of cases, depending on the dynamic tests used to diagnose hypopituitarism (Valdés-Socin & al 2009, Valdés-Socin & al 2015).Melatonin secretion and hormonal rhythms are severely disturbed in acute TBI patients (Seifman & al. Front Neurol 2014).Light is the primary variable that entrains the main circadian clock in the central nervous system. The retinohypothalamic tract generates an overt 24-hour rhythm. These coordinated outputs are conveyed through to the rest of the body via neuroendocrine (ie melatonin and ACTH-cortisol secretion), autonomic (sympathetic and parasympathetic pathways) and behavioral pathways (feeding, locomotor activity, etc).Finally, we will discuss some recent data connecting light pollution and nocturnal human activity with the metabolic syndrome (chronobesity).

This article aims to explore the transition process of informal camps on the French border to a sustainable state, similarly to « ghettoization ». I observe this issue as a result of a securitizationprocess. I started from the assumption that the ethical and cultural dimensions have particular relevance in this process. This issue requires a transversal analysis, of policies and speeches of actors at local, national and international levels. This is a question of integration policies at the local level more than a question of national or European immigration models. I aim to highlight the local the local level relevance, where the integration is primarily implemented, and therefore local and regional context should matter as much as the national model for the analysis of integration (Martiniello, 2013). In Calais, due to the lack of local immigration policies the civilian population has been pushed to react, they started to build temporary camps, this initiative increased the social exclusion. The civil associations gained more relevance and followers by Facebook, what changes the engagement that pass from local to transnational. In Calais the migratory flow and the informal camps called jungles are known since 1999, until May 2014 these camps around the city center possessed temporary vocation, and were destroyed and rebuilt daily. Therefore, this is also a matter of security speeches. The definition of the context as a crisis situation made possible an agreement between the associations and the government, that amidthe destruction of small camps and concentrated all refugees in a single area, 6.1 kilometers from the city. The political decisions concerning the space occupied by these individuals aimed to make them invisible, placing them far from the city and limiting their access to city services, which by consequence led to the construction of a ghetto. When a situation is defined as a crisis, it passes immediately to the state security sphere, where atypical actions, (as border militarization, mass expulsions, police repression), can be employed to protect the «political community» and eliminate the source of the crisis. This means that in a context defined as a crisis, temporality gains an important dimension, as evokes short term solutions, mobilizing more efforts in building urgency camps than in the areas related to integration. On the other hand the temporary camps, while urgent measures will endure and be normalised, becoming durable spaces of exclusion. The originality of this proposal is to discuss how local policy decisions and non-state actors worked together with a system of temporary camps for the implementation of a complex, semi-permanent exclusion system. This is a matter of contextual perception as a crisis situation, which is designed by production of speeches, and will determine the nature and timeliness of actions and political elaborations. The idea of the refugee crisis is then mobilized to justify emergency actions and security policies; such as closing borders, construction and maintenance of camps as an emergency response. [less ▲]

Human Chorionic gonadotropin (hCG) is a complex glycoprotein with several bioactive forms. These five variants comprise placental forms (hyperglycosilated hCG is the first form, then after 10 weeks of pregnancy total hCG takes over), cancer promoter forms (hCGb, hyperglycosilated hCGb), and a pituitary form (sulfated hCG). Current routine laboratory tests do not discriminate between these multiple variants of hCG. Low persistent detectable levels of hCG may be associated with various benign and malignant conditions, such as quiescent gestational trophoblastic disease, raised pituitary hCG, or false positive elevation caused by circulating heterophilic antibodies. Clinico-biological discussion are mandatory to avoid erroneous diagnosis and treatment.In this review we summarize and discuss the different causes of false positive hCG assay. We suggest that current gynecological protocols for the diagnosis and treatment of trophoblastic disease should consider the inclusion of hCG test in urine and/or a test for heterophilic antibodies, when appropriate to avoid unnecessary studies and treatment.

En 1972, L’Université de Liège inaugure STARESO: une station pour les recherches sous-marines et océanographiques. Posée sur la presqu’île de La Revellata, la station accueille depuis plus de 40 ans, des scientifiques de notre Université et du monde entier. La Méditerranée est considérée comme un mini océan, modèle pour comprendre l’océan mondial. Elle abrite une très grande biodiversité terrestre et marine mais c’est aussi une des mers les plus touristique au monde, zone subissant la littoralisation, la surpêche, la pollution... Les indices pour la détection de la pollution et pour la gestion des milieux marins permettent de visualiser, de montrer de manière synthétique et rapide, l’état des écosystèmes. A partir de STARESO, zone encore protégée de l’activité humaine, des indices définissant l’état des écosystèmes (DCE), des indices paysagers (qualité et valeur patrimoniale), des indices de pollution (teneur en éléments traces) et de colonisation par des espèces envahissantes ont été mis au point, validés scientifiquement et proposés aux gestionnaires du milieu marin. Après une description du site d’étude, du contexte écologique, cet exposé présente ces indices, les limites et les champs d’application en milieu marin. [less ▲]

Our studies have demonstrated that the thymus programs central self-tolerance to neuroendocrine functions through transcription of neuroendocrine-related genes in thymic epithelial cells (TECs). However, thymic neuroendocrine precursors are not secreted but processed as the source of neuroendocrine self-antigens that are presented by thymic proteins of the major histocompatibility complex (MHC). This process, highly specific of the thymus, has allowed an integrated and harmonious coevolution of the neuroendocrine and immune systems when recombination-activating genes and the subsequent adaptive immune response have emerged in cartilaginous fishes some 450-500 millions years ago. All the members of the insulin gene family are expressed in murine TECs under the control of AutoImmune Regulator (AIRE) according a precise hierarchy: Igf2 >Igf1>Ins2>Ins1. Igf2 transcription is defective in TECs of autoimmune diabetes-prone BB rats, and tolerance to insulin is severely impaired in Igf2-/- mice as well as in Igf2-loxP/Foxn1-cre mice with Igf2 deletion targeted in TECs. In addition, the diabetogenic coxsackievirus B4 (CV-B4) is able to persistently infect human and murine TECs and to inhibit Igf2 transcription and IGF-2 synthesis in a murine medullary TEC line (coolaboration with D. Hober, Laboratory of Virology, CHRU and University of Lille 2, France). These studies show that: 1° IGF-2 is the dominant tolerogenic precursor of the family and mediates cross-tolerance to insulin; 2° a thymus dysfunction plays a crucial role in the development of the diabetogenic autoimmune response; and 3° a thymic infection by CV-B4 is implicated in type 1 diabetes (T1D) pathogenesis. Most probably due to its very low level of expression in the thymus, the protein insulin is highly immunogenic and is the primary autoantigen tackled in T1D. On the basis of the tolerogenic properties of IGF-2, we are currently working on the development of a negative/tolerogenic self-vaccine against T1D. [less ▲]

Our studies have demonstrated that the thymus programs central self-tolerance to neuroendocrine functions through transcription of neuroendocrine-related genes in thymic epithelial cells (TECs). However, thymic neuroendocrine precursors are not secreted but processed as the source of neuroendocrine self-antigens that are presented by thymic proteins of the major histocompatibility complex (MHC). This process, highly specific of the thymus, has allowed an integrated and harmonious coevolution of the neuroendocrine and immune systems when recombination-activating genes and the subsequent adaptive immune response have emerged in cartilaginous fishes some 450-500 millions years ago. All the members of the insulin gene family are expressed in murine TECs under the control of AutoImmune Regulator (AIRE) according a precise hierarchy: Igf2 >Igf1>Ins2>Ins1. Igf2 transcription is defective in TECs of autoimmune diabetes-prone BB rats, and tolerance to insulin is severely impaired in Igf2-/- mice as well as in Igf2-loxP/Foxn1-cre mice with Igf2 deletion targeted in TECs.

Cette présentation aura pour but de proposer quelques pistes de réflexion autour de l’historiographie de la bande dessinée, que l’on envisagera de facto comme plurielle. Plus particulièrement, il s’agira de se pencher sur les façons dont les auteurs eux-mêmes participent à l’écriture de cette histoire dans la diversité de leurs pratiques. Alors que la bande dessinée pourrait être décrite comme un « art sans mémoire » (Groensteen, 2006), les différentes modalités de son inscription dans le temps et de la transmission de son passé constituent aujourd’hui une des questions cruciales de la recheche en bande dessinée. Prolongeant cet intérêt et en le confrontant à la perspective littéraire de L’Histoire littéraire des écrivains (Debaene, et al., 2013), cette présentation suggère que regarder à l’histoire et la mémoire de la bande dessinée telle qu’elle est transmise, véhiculée, réinventée ou rejetée par ses auteurs constitue un changement de perspective qui nous invite à prendre acte de la pluralité des histoires du médium.

The Hubble Space Telescope's high resolution observations of the Jovian aurorae in the UV domain have provided us with a wealth of new information in the recent years. Not only do we have now access to details down to a couple hundreds kilometers, but we can also analyze changes on timescales of tens of seconds. These images and spectra have taught us that the aurorae are made of many different features, each of them associated with a different process in the Jovian magnetosphere. This magnetosphere significantly differs from the Earth's one, being dominated by the rapid rotation of Jupiter and the plasma originating from Io's volcanism. The satellite footprints are the auroral signature of the electro-magnetic interaction between the Galilean moons and the magnetospheric plasma rotating around Jupiter. In the case of Io, Europa and Ganymede, this signature takes the form of a chain of spots followed by an elongated tail of emission. The tentative identification of a Callisto footprint will also be discussed. Poleward of Io's footprint, patches of emission of various sizes have been associated with injections of hot coming from the outer magnetosphere into the middle magnetosphere. These spots ares thus important markers of the plasma circulation in the Jovian magetnosphere. In the same auroral region, more diffuse emissions are associated with pitch angle scattering in the magnetospheric area where dipolar magnetic field lines become elongated. The most striking feature of the Jovian aurorae is the main emission. This structure sometimes appears as a continuous auroral oval, but it can also display much more complex patterns, especially on the dusk side. Moreover, the brightness strongly changes with local time, as a response to the variability of the corotation enforcement currents and the partial ring currents in the middle magnetosphere. Directly poleward of the main emission, patches regularly appear on the night and dawn sides, in a region generally devoid of any emissions (the polar dark region). Such patches are thought to be a signature of the reconnection process that allows the release of the plasma coming from Io into the magnetotail. The dusk side of the area enclosed in the main emission, called the active region, is the locus of intense and transient (sometimes, even quasi-periodic) flares as well as more stable arcs and diffuse patches. Poleward of this area, stable filaments can sometimes be seen along the noon to midnight axis. Finally, the polar-most region, tentatively associated with open field lines, display rapidly fluctuating patches of emissions. All these polar emissions are very poorly understood and will thus be the subject of fascinating investigations from the Juno spacecraft, arriving around Jupiter on July 4th. [less ▲]

La danse et le cinéma sont proches par leur souci constant de l’organisation du temps et du mouvement. Ils n’ont d’ailleurs cessé de dialoguer tout au long du vingtième siècle. Dès les premières danses serpentines captées par les caméras Lumière et Edison en 1895, le filmage du corps du danseur devient un enjeu important. La rencontre du cinématographe et de la chorégraphie permet en effet de nouvelles formes d'agencement des corps et d’audacieuses figures de mouvements. En somme, lorsque la danse et le cinéma se rencontrent, on assiste à la réinvention du geste, de la représentation corporelle et du mouvement lui-même, ce que l’on verra à travers les exemples donnés par quelques maitres du ballet et du cinéma, comme Fred Astaire, Gene Kelly, Wong Kar-wai ou Quentin Tarantino.

1. Manuscript submitted to Elementa Last year we submitted a manuscript about air-ice CO2 fluxes measured in continuous with a chamber over the ice during INTERICE V experiment. The results show that sea ice shifts from: (i) a sink during ice crystals formation, (ii) a source during ice growth, (iii) return to a sink during ice melt. We attempt to reproduce these fluxes with the 1Dimension model developed by Martin and Sebastien in Moreau et al. (2015). The inversion between outward CO2 fluxes during ice growth and inward CO2 fluxes during ice melt depicts well the observations. However, the model strongly underestimates the fluxes during the cold phase if the formation rate of gas bubbles is low. Since ice is permeable throughout the cold phase, higher gas bubble formation rates lead to higher CO2 fluxes. The contribution of gas bubble buoyancy to upward flux was the main hypothesis of this manuscript. 2. TA-DIC compilation With the code developed by Martin (and others), we computed profile of DIC normalized to the mean ice salinity. We observe a reverse C shape with a depletion at the surface and more scattered data at the bottom. It’s striking to observe that at mid-depth (0.5 m), all data sounds to converge at the same value (around 480 µmol/kg). It makes us confident with the fact that we can gather data and compare them. The mean DIC value in the middle of the cores is similar to the sea surface water DIC in Antarctica. Our idea is that these value are due to simple brine rejection and that there is a depletion at the top and at the bottom. The bottom depletion is subject to biogeochemistry processes. While the top depletion may be due to the CO2 release during ice formation which lead to a potential CO2 flux out of the ice. For the time beeing, we aim to derive a budget of CO2 flux from this compilation. This will be presented at the next BEPSII meeting. 3.

In this paper, we consider a regression model in which the tail of the conditional distribution of the response can be approximated by a Generalized Pareto distribution. Our model is based on a semiparametric single-index assumption on the conditional tail index while no further assumption on the conditional scale parameter is made. The underlying dimension reduction assumption allows the procedure to be of prime interest in the case where the dimension of the covariates is high, in which case the purely nonparametric techniques fail while the purely parametric one are too rough to correctly fit to the data. We propose an iterative algorithm in order to perform their practical implementation. Our results are supported by some simulations. To illustrate the proposed approach, the method is applied to a novel database of operational losses from the bank UniCredit [less ▲]

L’architecture moderne et contemporaine en Wallonie et à Bruxelles reste, en dépit de la vitalité de sa production, le parent pauvre de la culture belge francophone. Mise à l’écart de toute investigation historique approfondie et d’un propos appréhendable par tous, il en résulte qu’elle demeure méconnue – voire rejetée – du grand public autant que des élus, faisant encore l’objet de frilosité dans les politiques de protection patrimoniale. C’est au départ de ce constat que la collection de guides a été initiée, avec l’ambition de publier des livres alliant rigueur scientifique et vulgarisation, associant les enjeux des politiques patrimoniales et touristiques régionales, et couvrant à terme l’ensemble du territoire de la Belgique francophone. En 2014, la parution du premier volume sur Liège, avec près de 400 bâtiments commentés, a posé les jalons méthodologiques de la collection, avant Mons & Coeur du Hainaut (sorti en avril 2015), Charleroi (septembre 2016) et Tournai (2017). Notre exposé se structure autour de deux axes. Le premier entend revenir sur les fondamentaux du projet en se concentrant sur les aspects méthodologiques et l’ambition de la collection. Sur quelles bases définir la modernité en architecture ? Comment positionner ce guide parmi les publications similaires en Europe ? Quels sont les outils développés et exploités pour le travail d’identification et de sélection ? Comment traduire formellement ces enjeux dans la structure des livres ? La seconde partie présente une sélection de réalisations, illustrant la formidable caisse de résonance que Liège, ville européenne de dimension moyenne, a rencontré avec les grands courants de l’architecture moderne et contemporaine.

Most often data from psychological, educational or medical research are collected by administering questionnaires to the participants. Such questionnaires are usually made of the same set of items (i.e. questions) and are designed to precisely target the studied latent trait: this is referred to as "linear testing". However, linear testing can be counterproductive in some specific situations. For instance, not all items can accurately target the latent trait (e.g., "easy" items are not informative for "highly able" participants), so that the duration of the test can be uselessly extended. Adaptive testing is an emerging paradigm that aims at selecting and administering each item on the basis of previously selected items and the responses of the participants. The selectuion of the item is made optimally so that the most informative item for the respondent is chosen. This permits, among others, to better target the true latent trait to be estimated, shortening then the test duration. In this talk, linear and adaptive testing will be sketched from an educational testing approach. Then, selected examples from the psychological, educational and medical litterature will be briefly reviewed to illustrate the potentially usefulness of adaptive testing. Pros and cons of this method will also be outlined. [less ▲]

We investigate multiqubit permutation-symmetric states with maxi- mally mixed reduced density matrices in the symmetric subspace [1]. Such states can be viewed as particular spin states, namely anticoher- ent spin states [2]. Using the Majorana representation of spin states in terms of points on the unit sphere [3], we analyze the consequences of degeneracies of the Majorana points and of a point-group symmetry in their arrangement on the existence of anticoherent spin states. We provide different characterizations of anticoherence and establish a link between point symmetries, anticoherence, and SLOCC classes [4]. We consider in detail the case of small numbers of qubits and solve the 4-qubit case completely by identifying and characterizing all 4-qubit anticoherent states. [1] D. Baguette, T. Bastin, and J.

We derive a markovian master equation for the internal dynamics of an ensemble of two-level atoms including the quantization of their motion. Our equation provides a unifying picture of the effects of recoil and indistinguishability of atoms beyond the Lamb-Dicke regime on both their dissipative and conservative dynamics. We give general expressions for the decay rates and the dipole-dipole shifts for any motional states, generalizing those in Ref. [1]. We find closed-form formulas for a number of relevant states (gaussian states, Fock states and thermal states). In particular, we show that dipole-dipole interactions and cooperative photon emission [2] can be modulated through the external state of motion. As an application of our general formalism, we study the spatial Pauli blocking of two fermionic atoms beyond the Lamb-Dicke regime [3]. [1] G. S.

The conference is an initiative of the GERPHAU lab, research group for Philosophy, Architecture, Urban (Architecture School of Paris La Villette, UMR 7218 CNRS-Lavue), in partnership with Cité de l'Architecture et du Patrimoine and philAU (a scientific thematic network : Philosophy, Architecture, Urban). This conference is also supported by ARENA(Architectural Research in Europe Network Association), a shared platform that aims to promote, support, develop and disseminate high-quality research in all fields of architecture in the widest sense. The proposal of the conference AT THE TURN OF THE EXPERIENCE is to start with the hypothesis that the architecture could be conceive as a way of enquiring on this new experience of the world. Because it provides precisely access to the experience modalities of the building world, we argue that it could in return reveal such a processing paradigm shift in the making of human settlements. We invite to re-invest and re-question its representation apparatus that it used to deploy on territories in order to translate in fictions and projects what these ones could become. To discuss about these apparatus just as such these possible translations, the conference is addressed to all researchers and practitioners, architects and creators, the experienced ones and the experiencing ones as well, whose works attempt to question what we build and to share what we face.

Despite the numerous studies on gay families, the current literature that has focused specifically on gay adoptive parent families remains rather limited. In Europe the laws on adoption by same-sex couples change radically from a country to another one. That’s why the experience of these families can be very different according to their country of residence. What are the main stressors that gay adoptive parents have to face? What are the strategies of coping built by these families? This exploratory research examines the stressors and the coping strategies of 18 gay adoptive families (12 from France, 6 from Belgium) with children aged from 3 to 10. Participants were recruited via adoption agencies. Belgian parents adopted their children through national full joint adoption. Conversely, French participants became parents through international adoption as “single parents” (even if they were in a relationship, just one of the partners was legally involved in the adoption). Semi-structured interviews were conducted with parents. Using grounded theory methods, analyses revealed that parents face different stressors such as the homophobia by social workers, the lack of support by families of origin and social context, the afraid of not being considered parents "like the others" and the worry about discrimination of their children. In the French sample, these stressors were increased by a long procedure in which the “legal parent” had to lie about his sexual orientation and the other parent had to hide himself in order to assure the success of the adoption procedure. This can have a negative impact on the couple's relationship, on the feeling of legitimacy about parental role, in the relationship with the child and with the extended family. To cope with these stressors, many adaptive strategies have proved to be useful: don’t hide the sexual orientation to the children, join adoption associations, share experiences with other gay parents, take care of the couple relationship, being in touch with accepting people and protect themselves from discriminatory people. This comparison between Belgian and French families’ experience allows us to understand the impact of the legal status on the life of gay parents and their children. [less ▲]

CHU de Liège The pineal gland is known by Anatomists since the middle ages. Andrea Vesalius described it in the chap VII of his monumental book "De humani corporis fabrica (1555)". René Descartes had the intuition that the pineal gland is a "third eye" and that is how his illustrator Florent Schuyl represented it in figure 34 of Descartes book "De Homine" (1662). As for the artists, some of them illustrated from their paintings some craniotomies in which the surgeon performs the extraction of the stone of madness. Thus, "the extraction of the stone of madness" from Pieter Huys, is exposed in the Museum of the Périgord (1561). Jan Sanders showed the same subject in his painting "The surgeon" (1550) exhibited in the Museo Nacional del Prado, Madrid. During the 20th century the anatomy and the physiology of the pineal gland will be revisited: it appears so that the pinealocytes are in close relationship to the photoreceptors. In certain animal species (birds, reptiles) the pinealocytes are also photosensitive: their pineal gland is directly sensitive to light. In addition, in humans, the pinealoblastomes may occur related to the "trilateral retinoblastoma syndrome" caused by mutations in the RB1 gene (13q14.2) (Plowman & al Clin Oncol 2004). These patients present with retinoblastoma in both eyes but also in the pineal. This only strengthens the intuition of Descartes as the pineal as a "third eye". As for the genetic and hereditary aspect, we had the opportunity as well as other authors, to describe the family presentation of pineal lesions with hypersecretion of melatonin (Allouch & al 2002). With the greater availability of Radiology and brain scans, it was discovered with interest that the pineal gland is often calcified. This calcification can be observed since the second decade of life. It is not yet established if the pineal gland should be considered a"stone of madness " however it is a sort of “cerebral lithiasis”. Indeed, during this oral presentation, we will show some data linking the pineal gland and the light to seasonal depression. "Folly" induced by the long winter nights can be prevented from light therapy treatment. Severe head trauma is associated to Hypopituitarism up to 10-35% of cases, depending on the dynamic tests used to diagnose hypopituitarism (Valdés-Socin & al 2009, Valdés-Socin & al 2015). A current research topic is the study of disturbance of circadian hormonal cycles and secretion of melatonin. The secretion of melatonin occurs at night, and its synthesis is made in the pineal gland and then discharged to the general circulation. However, there is a quantitatively most important melatonin production at the level of the digestive tract. This melatonin would have essentially a paracrine effect. The administration of melatonin in humans results in variable pharmacokinetics due to its hepatic metabolism and its urinary excretion. Membrane melatonin MT1 and MT2 receptors use G proteins transduction. They are distributed mainly in the CNS at the level of the retina, hypothalamic nuclei and the pineal gland. They are also found in the periphery and in endocrine glands. A third melatonin receptor or MT3 is intracellular: this is the quinone reductase enzyme that has an important role in protection against oxidative stress (Lucchetti & al FASEB 2010). A current research topic is the role of a variant MT2 receptor (Variant rs 10830963) in diabetology. Patients harbouring this variant has been shown to have a a decrease in the early phase of insulin secretion(Langenberg & al Diabetologia 2009), and have a higher fasting morning glycemia, and consequently, an increased risk of developing a type 2 diabetes. These findings were demonstrated in a meta-analysis involving 170 000 patients (Mao & al PLOS one 2012). The same variant has been identified in patients at risk of developing glucose intolerance and gestational diabetes (al Diabetologia 2012, Liao, Walford & al PLO one 2012) Melatonin is synthesized in the pineal gland from the conversion of tryptophan to serotonin. Enzymes such as alkylamine N-acetyltransferase (NAT) and of acetylserotonin O-methyltransferase (ASMT) ensure the synthesis of melatonin from serotonin. Apart from melatonin which can be prescribed as such in Belgium, there are synthetic analogs of melatonin such as CIRCADIN. AGOMELATONINE is available in France (lab SERVIER). VALDOXAN is a structural analogue of melatonin developed as a sedative antidepressant daily, which must be taken at sunset. It is a MT1 and MT2 melatonin receptor agonist and antagonist of the serotonin 5HT2C receptors. We can also mention RAMELTEON (TAKEDA lab), which is registered as an hypnotic. Références B Claustrat.
