La distinction des perspectives en première et troisième personnes est un apport récent et décisif de la phénoménologie à la psychopathologie (Parnas, Sass & Zahavi, 2012). La perspective en troisième personne, campée par les dernières versions du DSM ou par l’evidence based medicine, consiste en l’attribution depuis une position externe de signes cliniques repérés indépendamment du ressenti exprimé par le patient. L’exemple typique de ces signes est le délire et l’hallucination du schizophrène. Ces symptômes cristallisent les difficultés qu’éprouve le sujet à se reconnaitre affecté du trouble (l’anosognosie), et ce point est considéré par les modèles dominants comme une cible thérapeutique prioritaire. La visée de ces techniques, orthopédiques et psycho-éducatives, est que le patient parvienne à « reconnaitre » sa maladie. Selon cette perspective en troisième personne, il est attendu qu’il adopte, intègre la position propre à son évaluateur, et externe à sa subjectivité intrinsèque. La démarche opposée, celle de la prise en considération d’une perspective en première personne, interroge, considère et concentre son attention sur l’expérience subjective exprimée par le patient. Si l’on reprend l’exemple princeps de la schizophrénie, ce sont la « perte de l’évidence naturelle » des choses, un « trouble du sens commun » ou un « sentiment de diminution du soi » que verbalisent les patients. Ces signes cliniques, révélant l’expérience du soi, deviennent l’élément psychopathologique structurant et mettent en évidence une manière d’être-au-monde, ici schizophrénique. Le pari de cette journée d’étude consacrée à l’anorexie est de chercher à appliquer ce passage vers une perspective compréhensive en première personne pour les sujets affectés de ce trouble. Des travaux pionniers en la matière, bien que ne se réclamant pas de la phénoménologie, sont certainement ceux du psychiatre éthologue liégeois Albert Demaret (1979). Celui-ci, suggère, de façon quelque peu déconcertante, de ne plus focaliser l’attention prioritairement sur l’aspect purement médical relatif à la perte de poids et au refus alimentaire. Le comportement qui retient particulièrement son attention est l’altruisme (souvent alimentaire), qu’il considère comme « la composante la plus fondamentale du syndrome » (p. 152). Outre le fait de révéler les composantes adaptatives du trouble, son étonnant modèle permet d’entrer en consonance avec le discours des patients anorexiques qui, bien souvent, ne perçoivent pas leur minceur (mécanisme de déni) ou expriment que leur problématique ne se situe pas, selon eux, dans leur sous-alimentation. L’anosognosie anorexique et cet effroyable tendance à se priver d’alimentation au risque de mettre sa vie en danger, si l’on ouvre la porte à la perspective en première personne – si on laisse la parole au sujet –, laissent la place à un besoin (dont l’excessivité peut être reconnue) de s’occuper des autres, de les nourrir, mais aussi une hyper-attention au regard qu’on leur porte. L’investissement émotionnel et corporel des relations est souvent présenté comme étant insatisfaisant, voire comme étant l’élément moteur de leur mal-être. Ce pas de côté de la vision omnisciente du médical, assumant une remise en cause du pouvoir de domination qu’entraine la perspective en troisième personne, se révèle être un outil psychothérapeutique tout à fait pertinent. Il désacralise le problème de l’anosognosie, remet en cause le déni (ce mécanisme devient également celui de l’entourage de l’anorexique qui ne peut percevoir le surinvestissement altruiste), et ouvre la voie à une perspective intersubjective, co-construite. Cette journée d’étude a pour ambition de mettre en lumière cette préoccupation pour l’éprouvé anorexique, évoquer les modes de communication de ces patients et laisser place au discours qu’ils ont souvent du mal à livrer. Il se révèle que les apports de disciplines comme la philosophie ou l’anthropologie, ainsi que ceux de la pratique clinique sont des détours essentiels à ce programme d’étude. Nous discuterons également du symptôme anorexique lorsqu’il est secondaire à un psychotraumatisme (quelle place cette tendance à la restriction vient combler dans l’expérience de vie du sujet traumatisé). Cette journée est ouverte tant aux praticiens de terrain et personnes intéressées par les matières cliniques qu’aux chercheurs universitaires en sciences humaines. [less ▲]

Architecture refers to the overall shape of a tree and the spatial position of its components. Tree height determines the position in the forest canopy and access to light, while the amount and spatial distribution of the foliage depend on the depth and the width of the crown. The aim of this study is to understand how tree architecture varies across coexisting tropical tree species and relates to ecological strategies. Forty five coexisting tree species were sampled in the semi-deciduous forests of Northern Congo. Species were classified according to ecological strategies, specifically regeneration guilds: shade bearers (27 species), non-pioneers light demanding (14 species) and pioneers (4 species). For each species, 14–72 trees (968 trees in total) were measured over a large range of diameter (10–162 cm). At the tree level, we measured the diameter (D in cm), height (H in m), crown radius (Cr in m) and crown depth (Cd in m) and crown exposure index (CEI) was visually estimated. At species level, architectural traits were estimated at juvenile tree with diameter of 10 cm (H10, Cr10 and Cd10) and at adult stature with maximum diameter (Hmax, Crmax and Cdmax), life history traits (dispersal mode, phenology and regeneration guild) and functional traits (wood density and light requirement) were obtained. Our results showed a significant variation in tree allometry between coexisting species. The interspecific variation was related to light requirement (H-D allometry), dispersal mode (Cr-D allometry) and liana infestation (Cd-D allometry). Large-statured tree species were light demanding, deciduous and wind dispersed, while small-statured tree species were evergreen, dense wooded, and animal dispersed. Architectural traits strongly differed between regeneration guilds. [less ▲]

The Juno mission offers the opportunity to study Jupiter, from its inner structure, up to its magnetospheric environment. Juno was launched on August 2011 and its Jupiter orbit insertion (JOI) occurred on July 4th 2016. The nominal Juno mission involves 35 science polar-orbits of 14-days period, with perijove and apojove distances located at 0.06 Rj and 45 Rj, respectively. Juno-UVS is a UV spectrograph with a bandpass of 70<λ<205 nm, designed to characterize Jupiter UV emissions. One of the main additions of UVS compared to its predecessors (New Horizons- and Rosetta- Alice, LRO-LAMP) is a 2.54 mm tantalum shielding, to protect it from the harsh radiation environment at Jupiter, and a scan mirror, to allow for targeting specific auroral and atmospheric features at +/- 30˚ perpendicular to the Juno spin plane. It will provide new constraints on Jupiter’s auroral morphology, spectral features, and vertical structure, while providing remote-sensing constraints for the onboard waves and particle instruments. It will also be used to probe upper-atmospheric composition through absorption features found in the UV spectra using reflected solar UV radiation. For example, stratospheric hydrocarbons such as C2H2 and C2H6 are known to absorb significantly in the 150-180 nm regions, and these absorption features can be used to determine their abundances. We will present our search for the spectroscopic features seen in Jupiter’s reflected sunlight during the first perijove. [less ▲]

We present movies of the Hubble Space Telescope (HST) observations of Jupiter’s FUV auroras observed during the Juno approach phase and first capture orbit, and compare with Juno observations of the interplanetary medium near Jupiter and inside the magnetosphere. Jupiter’s FUV auroras indicate the nature of the dynamic processes occurring in Jupiter’s magnetosphere, and the approach phase provided a unique opportunity to obtain a full set of interplanetary data near to Jupiter at the time of a program of HST observations, along with the first simultaneous with Juno observations inside the magnetosphere. The overall goal was to determine the nature of the solar wind effect on Jupiter’s magnetosphere. HST observations were obtained with typically 1 orbit per day over three intervals: 16 May – 7 June, 22-30 June and 11-18 July, i.e. while Juno was in the solar wind, around the bow shock and magnetosphere crossings, and in the mid-latitude middle-outer magnetospheres. We show that these intervals are characterised by particularly dynamic polar auroras, and significant variations in the auroral power output caused by e.g. dawn storms, intense main emission and poleward forms. We compare the variation of these features with Juno observations of interplanetary compression regions and the magnetospheric environment during the intervals of these observations. [less ▲]

Juno-UVS is an imaging spectrograph with a bandpass of 70<λ<205 nm. This wavelength range includes important far-ultraviolet (FUV) emissions from the H2 bands and the H Lyman series which are produced in Jupiter’s auroras, and also the absorption signatures of aurorally-produced hydrocarbons. The Juno-UVS instrument telescope has a 4x4 cm2 input aperture and uses an off-axis parabolic primary mirror. A flat scan mirror situated near the entrance of the telescope is used to observe at up to ±30° perpendicular to the Juno spin plane. The light is focused onto the spectrograph entrance slit, which has a “dog-bone” shape, with three sections of 2.55°x0.2°, 2.0°x0.025°, and 2.55°x0.2° (as projected onto the sky). Light entering the slit is dispersed by a toroidal grating which focuses FUV light onto a curved microchannel plate (MCP) cross delay line (XDL) detector with a solar blind UV-sensitive CsI photocathode. The two mirrors and the grating are coated with MgF2 to improve FUV reflectivity. Tantalum surrounds the spectrograph assembly to shield the detector and its electronics from high-energy electrons. All other electronics are located in Juno’s spacecraft vault, including redundant low-voltage and high-voltage power supplies, command and data handling electronics, heater/actuator electronics, scan mirror electronics, and event processing electronics. The purpose of Juno-UVS is to remotely sense Jupiter’s auroral morphology and brightness to provide context for in situ measurements by Juno’s particle instruments. Here we present the first near-Jupiter results from the UVS instrument following measurements made during PJ1, Juno’s first perijove pass with its instruments powered on and taking data. [less ▲]

Baltic sub-populations of harbour porpoises Phocoena phocoena meet in in Southwestern waters in Spring when females reach the coastal areas for calving and nursing. In Autumn they separate again for reproduction : the Belt sea populations westwards in the Kattegat/Skarregat region, the Baltic proper population northwards in the central basin. The increased number of juvenile and newborn strandings along the German Baltic coasts give evidence for a possible existence of local calving grounds in this area. Calving and nursing habitats are the most important areas for management purposes. This project aimed to describe inhabitancy and diet of females and calves along the German Baltic coast, in order to achieve effective conservation measures. Nitrogen, carbon and, for the first time, sulphur stable isotopes (δ13C, δ15N and δ34S) were analysed in coastal species of fish and invertebrates in spring, autumn and winter 2015/2016 and in four different areas, to assess for seasonal and geographical variation of porpoises habitat use. The structure of ecological niches was inferred within and between communities using the SIBER model, and was compared to results from stomach content analysis. N, C and S values of fish and invertebrates strongly varied, seasonally and geographically, as a consequence of environmental factors characteristic of each sampling area. Additionally, each species presented large isotopic variability, suggesting possible intraspecific dietary specialisations. Females δ13C and δ34S signatures integrated both open-waters and coastal feeding, while juveniles presented a more coastal distribution. The absence of difference in δ15N values between age classes confirmed persistence of milk assimilation from the mothers. Niches structures and overlaps and stomach content analysis suggested gobies (Potamoschistus spp and Neogobius spp in particular), crabs and small coastal fish (ex. three-spined stickleback) as the main preys of juveniles. The integration of all three stable isotopes together permitted to well delineate even the highly dynamic food web of the Baltic German waters, confirming the use of sulphur isotopes in marine ecological studies.

Situer le récit d’anticipation dans l’histoire des pratiques culturelles, en particulier dans l’histoire littéraire, est une démarche problématique à plus d’un titre. L’une des résistances majeures est la tendance normative à réinterpréter les textes concernés en les classant soit dans les œuvres visionnaires géniales à sauver ponctuellement de l’oubli, soit dans les nombreuses prophéties non advenues ayant périmé à juste titre. Récit bref, roman ou essai fictionnel, le texte d’anticipation semble de la sorte condamné à cette réception binaire qu’il programme dans son pacte de lecture. Il s’emploie à traiter du futur alors même qu’il est étroitement lié à son premier contexte d’écriture par les réseaux éditoriaux, les supports médiatiques et les référents des représentations qui le composent. Cela contribue à le dater très fortement et à restreindre sa postérité à l’adéquation entre une visée prospective de la fiction et sa validation par l’Histoire. Le cas du récit d’anticipation invite ainsi à étudier la durée de vie de certaines productions culturelles au regard des constructions rétrospectives qui en sont faites : dans quelle mesure l’obsolescence contrainte d’un certain corpus littéraire peut-elle aider à penser la généricité dans l’histoire ? Les exemples choisis porteront sur un corpus francophone situé entre 1800 et 1950, période précédant l’émergence des collections françaises de science-fiction. On examinera spécifiquement les trois cas de figure suivants : les assises idéologiques du discours social (progrès, hygiénisme, saint-simonisme) chez Émile Souvestre (Le monde tel qu’il sera, 1846) ; l’anticipation mêlée à la satire journalistique dans l’œuvre d’Albert Robida et le tropisme du spectacle (théâtre, féérie, magie) dans l’esthétique du « merveilleux scientifique ».

La « rétromania » bat son plein dans le champ de la bande dessinée qui, aujourd'hui, ne compte plus les rééditions luxueuses des œuvres, canoniques ou oubliées, de son passé1. Les Sunday comics, pages dominicales des quotidiens américains où paraissaient en couleur le supplément de bande dessinée, ont fait l'objet d'une attention toute particulière, comme en atteste les rééditions à l'échelle originale réalisées par Sunday Press, magnifiant ces œuvres éphémères au sein d'ouvrages monumentaux. Art Spiegelman et Chris Ware, auteurs clés du roman graphique, ont directement été impliqués dans de tels projets, manifestant une continuité entre ces Sunday pages et leurs propres expérimentations avec la forme, illustrant bien l'adage de Spiegelman, « the future of comics is in the past ». La bande dessinée contemporaine, donc, semble être crucialement située à l'intersection d'une fascination rétrospective pour son passé, et d'une réinvention de ce passé, de l'exploration de « nouvelles » formes. Partant de ce contexte précis, qu'il s'agira d'approfondir, cette présentation examinera les Sunday comics comme « objets en mouvement » à travers l'œuvre de Cole Closser2, qui manifeste une « rétro-réflexivité3 » basée sur l'imitation non seulement du style de comic strips mais aussi sur l'évocation de leurs récentes rééditions. Closser mélange outils numériques et techniques obsolètes pour produire quelque chose qui veut se faire passer pour un objet du passé. L'œuvre de Closser ainsi met en avant les aspects matériels et haptiques liés à la reproduction de « vieux » comic strips, ainsi que le fétichisme lié à cette mise en scène matérielle de ces objets telle qu'on peut la trouver dans les designs des livres de Dan Nadel ou Chip Kidd4. Le cas de Closser est paradigmatique de la manière dont cette forme de rétro-réflexivité dépasse la question d'intertextualité pour interroger comment de « vieilles » bandes dessinées re-circulent en tant qu'objets au sein de la production contemporaine et donc au-delà du marché des collectionneurs. À partir du cas de Closser, cette présentation cherchera à mettre en lumière différents usages que ces objets du passé de la bande dessinée recouvrent au cœur du roman graphique contemporain, cartographiant un mouvement simultanément rétrospectif et orienté vers le futur.

Siting processes of high-level radioactive wastes remain a sensitive step for nuclear waste management organizations. At this stage, radioactive wastes programs become highly visible. Such concreteness increases controversies leading to modification or temporary standstill of the program (see e.g. strong local oppositions in the 80’s in Canada and in France). These controversies have often forced nuclear waste management organizations to include larger societal groups (civil society, NGO’s, parliamentarians, lay people,…) and to recognize the societal dimension of such issue. The program is thus recognized as a sociotechnical one, compelling authorities to a new approach to territorial development (Leloup 2010). At the local scale, new instruments and strategies have been adopted and implemented to tackle this territorial question. One of these tools is the local information committee. Considering nuclear waste management as an art of government (Dean, 2010), this presentation focuses on the siting processes of radioactive wastes programs and analyzes the coproduction between territory and program (Jasanoff 2004). It therefore studies the influence on the programs of the local publics through their local information committee in two specific cases: the French and the Canadian high-level radioactive wastes programs. To do so, it mobilizes official documents, participatory observations, two ethnographic fieldworks (Bure – France and Manitouwadge, Ignace, Schreiber and Nipigon – Canada), and semi-structured interviews. These interviews were conducted with French and Canadian nuclear waste management organizations’ member, regulators, local representatives and local consultation committee’s members. In analyzing such siting processes, we first analytically describe the shift from a national radioactive waste management program to a territorialized management in France and in Canada. Second, it aims at understanding the concrete and sometimes unanticipated effects of implementing a management program at the local level by focusing on the integration of local publics and stakeholders in the decision-making of such processes. Finally, it discusses the dual relationship between program and territory in these processes. Our results highlight that the territorial development of the high-level radioactive wastes programs started within R&D programs although the program was officially presented as “placeless” (Murphy 2009). They also show that the siting processes have been designed very differently. In Canada, the siting process has been co-designed with publics while the French national Parliament has imposed a siting location for the industrial project. Third, through the (in)actions of such local committees considered as invited critics (Wynne 2007), new socio-technical adjustments has occurred in these programs. Even though, we stress that the dichotomy between expert-based and participatory is still pregnant (for different reasons) and reinforce the dichotomy between nature/experts/underground and society/publics/ground.

Digital Humanities is flourishing in Belgium. There are Virtual Research Environments (VRE) for studying transnational intellectual collaborations in the area of social reform and the political and social history of the Belgian justice system. Tools being developed to digitally uncover the genetics of manuscripts or create a linked data structure to map networks across the ancient world. Furthermore, Electronic Literature across Europe is being mapped and video games are being studied using humanities research methods. The digitisation of artistic, historic and scientific collections is also a key priority in Belgium. With the Belgian Art Links and Tools platform, BALaT, the development of a Data Hub for Museums and Belgium’s digitised newspapers in Belgica Press being flagship examples. Alongside this rich tapestry of activities, Belgium is a Founding Member of DARIAH-EU, the Digital Research Infrastructure for the Arts and Humanities. The aim of DARIAH in Belgium is to develop and offer a sustainable portfolio of services enabling digital scholarship in the arts and humanities in Belgium and beyond. To realise this, partner institutions within Belgium are in the process of establishing Digital Humanities Research Centres which together will form a humanities-specific digital ecosystem, offering services both within their own institutions and to other institutions in Belgium. Additionally, selected services will be scaled-up for use within the European DARIAH community, and offered as in-kind contributions to DARIAH-EU. In this paper we will explore both the intra- and inter-institutional context of digital humanities centres in Belgium. Starting at the intra-institutional level, we will introduce two existing digital humanities research centres: the Centre Informatique de Philosophie et Lettres (CIPL, Université de Liège) in the French-speaking part of Belgium and the Ghent Centre for Digital Humanities (GhentCDH, Ghent University) in the Dutch-speaking part of Belgium. We will examine both the organisational goals of these centres and how they support digital humanities research within the university, with a particular focus on the collaborations they set up on an institutional level (for example with IT services and the library as well as between research groups). Furthermore, we compare these existing centres, with the newest digital humanities centre in Belgium, the Leuven Centre for Digital Humanities (LCDH) which is currently in the process of being established in the Dutch-speaking university and DARIAH partner institution, KU Leuven. Finally, we will analyse the opportunities and challenges in the inter-institutional context. While challenges such as the complex funding landscape and multilingual research environment should not be underestimated, there are many opportunities that can be celebrated. For example, collaborative training initiatives, such as Research Community Digital Humanities Flanders, which is open to members beyond Flanders, the annual DH Benelux conference which offers a platform for collaboration between digital humanities projects in Belgium, the Netherlands and Luxembourg and joint-funding opportunities such as the Belgian Research Action through Interdisciplinary Networks (BRAIN) programme. Additionally, activities for participation in DARIAH-EU, including preparing Belgian in-kind contributions and establishing DARIAH Working Groups not only addresses these challenges, but contributes to ensuring that digital humanities activities in Belgium thrive.

Dès ses premières tentatives d’expansion sur le marché domestique, le jeu vidéo est marqué du sceau d’une double obsolescence : obsolescence ​te​chnique, qui régulera de plus en plus la durée de vie des dispositifs de jeu, mais également​ es​thétique, poussant le consommateur à remplacer des machines que la succession rythmée des « générations » rend rapidement désuètes. Cette obsolescence double est renforcée par l’omniprésence dans les discours de la course à la technologie : la presse spécialisée entretient la promesse de « lendemains qui chantent » (Triclot, 2016), glorifiant l’avenir du jeu vidéo. Ce motif récurrent se diffuse également dans les médias généralistes — qui, pendant plusieurs décennies, puisent dans la dimension économique du médium un des seuls discours bienveillants le concernant (Delbouille, 2018) — ainsi qu’auprès du grand public. A contrario, plusieurs pratiques culturelles développées par les joueurs viennent répondre à cette fuite en avant : d​ u ​retrogaming ​ au ​retromaking, de l’émulation aux politiques de patrimonialisation du médium (Barbier, 2014), ces pratiques ​constituent autant de tactiques (De Certeau, 1990) de résistance face à cette stratégie industrielle. Elles permettent ​alors d’aborder différemment, par exemple, l'histoire du jeu vidéo ​— qui n'est encore généralement envisagée que par le biais de sa dimension technique. Par la rupture qu’elles semblent marquer ​avec les productions dominantes, ces pratiques se situent « en décrochage » par rapport​ ​à la temporalité de l’industrie. L’objet de cette communication, en faisant dialoguer ces deux dynamiques, est de constituer l'obsolescence en tant qu’outil d’analyse des enjeux culturels du jeu vidéo. En résistant à l'obsolescence, en refusant l'expiration d'anciennes ​« ​delivery technologies » (Jenkins, 2013), les amateurs (Hurel, 2017) affirment l'existence d'un média jeu vidéo à part entière. Quant aux acteurs industriels, en réintégrant ces pratiques de décrochage au sein de leur course technologique, ils semblent arpenter une ligne de crête ​— cherchant ​à bénéficier d'un statut culturel qui leur serait bénéfique, sans pour autant abandonner le cœur de leur moteur économique.

- Introduction: Graft-versus-host disease (GVHD) remains one of the major complications following haematopoietic stem cell transplantation (HSCT). Approximately 15% of the patients with chronic GVHD develop the sclerodermatous form of the disease characterized by multiple organ fibrosis and loss of skin elasticity. Several studies have shown the potential benefits of imatinib, a tyrosine kinase inhibitor (TKI), as a treatment of fibrosis in cGVHD due to its ability to inhibit simultaneously PDGF-R and c-Abl pathways which are both involved in fibrosis mechanisms. - Aims: Some early-phase clinical studies have assessed the impact of TKIs in patients with steroid-refractory cGVHD. Unfortunately, these studies yielded to conflicting results underlying the importance of re-assessing the impact of imatinib in scl-cGVHD pre-clinical models. This work investigates the possible benefits of imatinib on fibrosis in a murine model of sclerodermatous chronic GVHD (scl-cGVHD). - Methods and results: Lethally irradiated Balb/cJ mice (7 Gy TBI) were injected i.v. with 1.106 or 10.106 bone marrow cells and 2.106 or 70.106 splenocytes from B10.D2 donnor mice (Moderate and Classical scl-cGVHD models respectively). Mice were then treated with sterile water or imatinib (150 mg/kg/day) by oral gavage from day +7 to day +52 following transplantation. cGVHD severity was assessed three times/week with a scoring system encompassing 5 criteria (mice posture, weight loss, activity, hair loss, skin integrity ; 0-1-2 point(s)/criteria). Skin biopsies were performed on day +29 following transplantation to assess phosphorylation of c-Abl (TGF-β pathway) and PDGF receptor. Our results show that imatinib failed to prevent/improve GVHD with a similar evolution of the GVHD severity with no differences between groups (neither in moderate cGVHD model, nor in the classical cGVHD model). Mice weight loss during the experiments was also comparable between groups in both models of cGVHD. In the classical model, histological analyses indicate a significant reduction of the phosphorylation level of the PDGR receptor (p = 0.0079). In vivo cell proliferation assay with CFSE were also performed and showed a reduced proliferation of T cells and subsets (CD4, CD8 and Tregs) in spleen, lymph nodes, bone marrow and blood after imatinib treatment. Finally, FACS analyses performed on days +21 and +35 after transplantation did not show any differences in the absolute T-cell counts. - Conclusions: Although we have observed a decreased phosphorylation level of PDGR receptor and less proliferation of T cells and subsets in vivo, imatinib failed to alleviate scl-cGVHD both in moderate and classical murine models of scl-cGVHD.

On the cusp of the 1980s, when it became increasingly apparent that humanity had left its mark on every inch of the surface of the earth and altered its atmosphere, the idea of a strictly natural world became obsolete and needed to be reimagined. As a result, American environmentalist Bill McKibben presented in his essay The End of Nature (1989) the hypothesis of a postnatural world, a world in which nature has ended ‘both as a discrete biophysical entity and as a meaningful concept’ (McKibben, 1989). This presentation will aim at demonstrating how American civilisation ‘planned’ the obsolescence of both nature and the self through its yearning for progress, production and for the accumulation of manufactured products and wealth. Besides commenting on McKibben’s essay, I will draw parallels between other works such as Henry David Thoreau’s memoir Walden (1854) and Don DeLillo’s novel White Noise (1985) in order to illustrate how the evolution of the American process of self-realisation that was originally connected to the natural landscape led to the fragmentation of the self in the postmodern landscape as expressed, for instance, in Fredric Jameson’s book Postmodernism, or, the Cultural Logic of Late Capitalism (1991). I will also argue that Thoreau anticipated the notion that a construction of an identity based on a transcendental relationship with sublime nature was soon to be replaced by a transcendental experience with objects of consumption¬—or waste—or, more largely, with the postmodern sublime landscape. I will show that American literature may be at odds with Bernard London’s representation of consumer capitalism and with his description of planned obsolescence as a means of ‘salvation’ for the American people (London, 1932).

Health- and disease-related events may be of highly significance for patients and their relatives. Naming a medical diagnosis is one of them. It carries the inherent power of (re)configuring the individuals' life courses, which are moreover closely linked to those of their relatives, and especially blood families in the case of (hereditary) genetic diseases. Drawing on ethnographic observations and narratives from patients and relatives involved in some Belgian organizations concerned with genetic disorders, this paper is interested in the ways these concerned people make sense of the naming of a medical diagnosis event by (re)interpreting their past familial stories, trying to intervene in the present, and designing a desired future. Then, it explores the case of the annual charity TV show "Téléthon", which is an initiative launched at the initiative of some French-speaking patients’ organizations (POs) concerned with neuromuscular disorders in the aims at putting awareness on rare disorders and raising funds in order to support biomedical research, especially in the field of medical genetics. The point is to question the dynamic relationships between the individual and familial experiences and such collective mobilizations, that is to say the dynamic relationships between individual and collective dimensions of POs' evidence-based activism. The argument is that such forms of activism participate in the co-construction of "gene worlds" (Timmermans & Shostak, 2015), through the relations between various actors and institutions: POs, scientific and medical professionals, public health institutions, and healthcare systems.

Science communication is undergoing a considerable evolution in the Internet era. Open Access is at last letting researchers, scholars and students in developing countries acquire full access to scientific knowledge. Nowadays, this represents a bit less than half of the scientific literature, the other half being still hidden behind paywalls and unaffordable by them. Unfortunately, in order to preserve their highly profitable business model, the major publishing companies are flipping the model from "pay to read" to "pay to publish". This is the most important threat for African and other developing countries: the price to pay for reading freely is the loss of opportunity to communicate. A truly democratic future, at the international level, calls for publicly run open publication platforms accessible to all, submitted to open reviewing and immediately accessible. This novel communication tool can only be attractive upon two conditions: 1) it must be attractive enough so that the researchers become aware of the advantages it provides in terms of audience, visibility and potential citations; 2) the research/researcher evaluation processes must take the new paradigm in consideration and quit using the current indirect metrics (proxys) such as the journals impact factor. However, this indispensable change in the evaluation tradition must be adopted worldwide and at the same time if no scientific community, particularly the young generation, is to be sacrificed.

Face à l’extension du champ de l’intervention sur l’existant et au brouillage des limites entre rénovation et restauration d’édifices et d’ensembles allant du monument historique au bâti générique, ancien ou récent, il semble plus que jamais utile d’accepter la notion de bricolage conceptuel et de réfléchir à une « boîtes à outils » permettant aux futurs architectes de faire face à la complexité des enjeux de la réhabilitation. En effet, face à ceux-ci, les théories de la restauration monumentale qui sont enseignées dans les instituts et facultés d’architecture atteignent parfois leurs limites et nous semblent devoir être complétées par/confrontées à de nouveaux concepts ou théories susceptibles d’élargir et même de renouveler notre vision des choses. C’est ainsi que depuis plusieurs années, nous avons choisi de faire un pas de côté et d’interroger des champs aussi éloignés que la logique formelle, l’ontologie de l’art et les théories littéraires et travaillons actuellement à une anthologie critique de textes variés mais tous susceptibles d’intéresser les conservateurs (du patrimoine mobilier et immobilier) et donc aussi, les architectes intervenant sur l’existant. Parmi ces textes, oeuvres d’auteurs en grande partie méconnus dans le champ du patrimoine, « Identity, Origin and spatio-temporal continuity », du philosophe Théodore Scaltsas, professeur à l’université d’Edimbourg, et extrait d’une revue en grande partie écrite en langage mathématique, nous parait particulièrement intéressant à analyser lors du séminaire. En utilisant des exemples aisément transposables au milieu de l’architecture, il aborde notamment la question de l’intention d’une reconstruction de manière originale et interpellante, qui n’autorise plus les fréquents amalgames justifiant tout et n’importe quoi et émanant non seulement du monde économique mais aussi des milieux du patrimoine dits autorisés. Par ailleurs, il enrichit le débat sur l’authenticité d’une dimension peu prise en compte à ce jour et particulièrement éclairante dans le cas des productions modernes et contemporaines, qui constituent l’un des enjeux les plus actuels de la réhabilitation.

As Christopher Manes writes, ‘[n]ature is silent in our culture […] in the sense that the status of being a speaking subject is jealously guarded as an exclusively human prerogative’ (Manes, 1996). According to this view, nature is less silent than silenced, the difference lying in a refusal to have a relationship with the natural world because of the lack of adequate language to describe our relationship with our natural environment. Human faculties promoted by the Enlightenment have led humans to believe that our language ‘ha[s] no analogues in the natural world’. I will show that American authors such as Henry David Thoreau, John Muir, Aldo Leopold or Edward Abbey accounted for a multi-sensorial experience of nature that betrays an attempt to find a form of language that would relate humans to natural elements. Although nature does not ‘speak’, I will argue that humans were provided with their sensory perception that allows them to appreciate worldness and to develop a harmonious relationship with the rest of the world. I will also stress that our alienation from the natural world is as much a cultural problem as it is a consequence of Western consumer capitalism and supermodernity, as suggested, for example, in Don DeLillo’s White Noise (1985). Adopting an ecocritical approach, I will examine the ways in which we tend to perceive worldness as silent and how literary texts may revive worldness and world as essential concepts in the study of the relationship between literature and our physical environment.

Herodotus, in the Lydian logos of his first Book, more particularly in the context of the History about Croesus, relates that the Lydian king began his reign with a series of military campaigns against the Greek cities of Asia Minor. Ephesos was the first one to suffer and, according to the historian, it was during this campaign that the inhabitants of Ephesos have linked the city-walls to the Artemision, in order to dedicate the city to the goddess. In my presentation, I will reconsider the archaeological excavations of the Artemision and the city of Ephesos by the British and the Austrians. Uncovered fragments of Greek and Lydian inscriptions indicate that Croesus made offerings to the sanctuary. As for the Lydian inscription, I can propose a new reading in light of the works dealing with the Lydian kings’ onomastic. I will also reconsider the results of excavations searching for the Archaic City (not yet surely localised), for which no defensive wall has ever been uncovered so far. Thus, the comments of Herodotus and even Polyaenus cannot find any archaeological confirmation. Moreover, it appears that the episode of the rope linking the Artemision to the City of Ephesos has been an imagined story inserted by Herodotus in his Histories (then repeated by Polyaenus). Eventually, it seems that Croesus never besieged the city, with Ephesos surrendering to the Lydian king without any conflict. [less ▲]

A new type of Martian aurora, characterized by an extended spatial distribution, an altitude lower than the discrete aurora and electron precipitation up to 200 keV has been observed following solar activity on several occasions with the IUVS on board the MAVEN spacecraft. We describe the results of Monte Carlo simulations of the production of several ultraviolet and visible auroral emissions for initial electron energies from 0.1 to 200 keV. These include the CO2+ ultraviolet doublet (UVD) at 288.3 and 289.6 nm and the Fox–Duffendack–Barker (FDB) bands, CO Cameron and Fourth Positive bands, OI 130.4 and 297.2 nm and CI 156.1 nm and 165.7 nm multiplets. We calculate the nadir and limb intensities of several of these emissions for a unit precipitated energy flux. Our results indicate that electrons in the range 100-200 keV produce maximum CO2+ UVD emission near 75 km. We combine SWEA and SEP electron energy spectra measured during diffuse aurora to calculate the volume emission rates and compare with IUVS observations of the emission limb profiles. The strongest predicted emissions are the CO2+ FDB, UVD and the CO Cameron bands. The metastable a 3Π state which radiates the Cameron bands is deactivated by collisions below ~110 km. As a consequence, we show that the CO2+ UVD to the Cameron bands ratio increases at low altitude in the energetic diffuse aurora. [less ▲]

La diversité des grands prédateurs marins est souvent vue comme un indicateur de la santé des écosystèmes océaniques (Fröbisch et al.,  2013; Scheyer et al.,  2014; Kelley & Pyenson,  2015). Cependant, les moteurs, les causes des renouvellements fauniques sont souvent méconnus pour les animaux occupant les niveaux supérieurs des chaînes trophiques. Il est donc nécessaire d’identifier et de démêler les mécanismes qui dictent les fluctuations de la biodiversité fossile – y compris les multiples biais affectant ces données (ex. Benson et al.,  2010). Le Crétacé offre une occasion fantastique d’étudier cette relation, étant caractérisé par un climat globalement chaud mais variable et un assemblage diversifié de reptiles, ostéichtyens et néosélaciens qui régissaient les chaînes trophiques marines (Bardet et al.,  2014; Guinot & Cavin,  2015) et qui ont subi des perturbations majeures durant le Crétacé. L’approche choisie ici est résolument macroévolutive et exploratoire. Je combine révisions taxonomiques et analyses phylogénétiques avec des méthodes de reconstruction de la diversité (richesse taxonomique, disparité, diversité écologique) et la vitesse d’évolution dans le but de détecter et de quantifier les renouvellements majeurs des assemblages de reptiles pélagiques crétacés. Ensuite, ces variables sont confrontées aux données climatiques et une nouvelle approche pour rendre compte de la dynamique de ces fluctuations est proposée ici (voir également Fischer et al.,  2016). L’histoire des ichthyosaures et les pliosaures, les prédateurs dominants du Crétacé inférieur disparaissant « prématurément » (durant l’intervalle Cénomanien-Turonien), a été analysée au moyen de ces techniques quantitatives et montrent, contre toute attente, des trajectoires fort similaires avec un pic de diversité-disparité dans le Crétacé inférieur (de part et d’autre de l’Hauterivien) précédent des constrictions importantes de biodiversité vers l’Aptien et au Cénomanien. Les analyses indiquent que les taux d’extinctions chez les ichthyosaures se corrèlent avec l’importance des fluctuations climatiques, offrant une nouvelle perspective pour expliquer leur extinction abrupte durant le Cénomanien.

Structural boundaries in ecosystems play an important role both in the context of seascape architecture, ecological processes and biodiversity. The Mediterranean Seagrass Posidonia oceanica (L.) Delile is considered an ecosystem engineer species, forming habitats of great ecological value and providing many ecosystem services. This study aims to (1) determine whether there are differences between seagrass-sand corridors edges and the adjacent continuous meadow, and (2) investigate whether anthropogenic pressures can cause disturbances in the measured parameters along the edges and the meadow. We have developed a multidisciplinary approach combining plant physiology, faunal canopy community studies and seagrass structural parameters characterization. We performed in situ chlorophyll fluorescence measurements using a Pulse Amplitude Modulated (Diving-PAM) fluorometry in order to assess the photosynthetic rate of the shoots. Vagile macrofauna of the leaf stratum was sampled by a hand-towed net, and the major taxonomic groups were sorted, counted, and identified. Meadow’s biometric measurements and the epiphytic biomass were also determined. Regarding edge-meadow matrix, results have shown highest differences on matrix structural parameters such as shoot density and shoot type proportions. Shoot density was found to decrease in edges considerably. We found c.a to 60 % plagiotropic shoots on edges while in continuous meadow orthotropics were predominant (up to 90 %). Howerver vagile-fauna population densities and diversity did not differ significantly among stations studied, neither by sites. Photosynthetic rate and leaf surface values also did not show changes between edges and continuous meadow. However, results did show that plagiotropic shoots had higher photosynthetic rate than orthotropics, and also that epiphyte abundance sorted out to be much higher (up to 54 %) on edges. [less ▲]

Du fait de sa position stratégique entre l’Afrique du Nord et l’Afrique subsaharienne, le Niger est une terre d’intense mobilité par le départ et le transit de nombreux migrants dont le flux venait de tous les pays de l’Afrique de l’Ouest. Le contexte géopolitique actuellement dominé par l’insécurité dans la partie Est du pays et le nord du Nigeria voisin (guerre imposée par la nébuleuse Boko Haram) ; et l’instabilité des pays frontaliers à l’Ouest (Mali) et au Nord (Libye) poussent les populations à chercher refuge en migrant massivement (plus de 60% des migrants en direction du Maghreb et l’Europe passent par le Niger selon l’Organisation Internationale pour les Migrations) et irrégulièrement vers les grandes villes minières du nord du Niger (Agadez, Arlit, Djado et Dirkou) qui sont les portes d’accès au pays de l’Afrique du Nord et ensuite à la méditerranée afin d’atteindre les pays européens. A tous ces problèmes sécuritaires, s’ajoute le problème d’insécurité alimentaire et foncière qui oblige les populations rurales comme celles de la région de Tahoua à migrer pour un exode temporaire ou saisonnier qui finira par une migration de longue durée à force de prendre goût à l’aventure. Les ruraux qui font face aux déficits cycliques imposés par le changement climatique vont à la recherche du mieux-être et du complément alimentaire des ménages. Cet article traite de l’exode qui sera considéré comme une migration locale et en même temps une initiation à la migration régionale et intercontinentale. Il ressortira les impacts socio-économiques de l’exode agissant sur les ménages dans la région de Tahoua au Niger. [less ▲]

Introduction: Isoinertial contractions are effective to generate maximal force during the initiation of the movement whereas they do not provide an appropriate training stimulus to generate force once accelerative phase has been developed (1). Pneumatic resistance is one alternative that has been developed to overcome the aforementioned limitations associated with isoinertial contractions. This technique allow higher initial velocity and reduce the decrease of force towards the end of the concentric phase (1). There is some training interest by combining isoinertial and pneumatic loading. The aim of this study was to determine how different isoinertial-pneumatic ratio influence the force-velocity-power relationships during bench-press. Methods: Fifteen participants performed bench press at 30%, 45%, 60%, 75%, and 90% of their 1RM, with five isoinertial(I)-pneumatic(P) resistance ratio : 100%I/0%P, 75%I/25%P, 50%I/50%P, 25%I/75%P, and 0%I/100%P. Velocity, force and power were assessed using a linear transducer and mechanical parameters measured by the pneumatic ergometer. Force-, velocity- and power-time patterns were averaged over the push-off phase to build the corresponding force-velocity and power-velocity relationships for each resistance ratio. Results: The increase in pneumatic part in resistance ratio elicited higher movement velocity and lower force level from 0% to 80% of the concentric phase. The increase in isoinertial part in resistance balance resulted in higher velocity towards the end of the movement. As a consequence, the use of isoinertial resistance oriented the force-velocity relationship towards force, whereas pneumatic resistance elicited a more velocity-oriented profile. Conclusion: Pneumatic-oriented resistance could be used to develop initial velocity and force towards the end of the push-off. Isoinertial-oriented resistance should be used to develop maximal force and maximal power. Resistance modality could be modulated according to training objectives. Références : 1. Frost et al.

À la suite d’une analyse de la mise en débat du marxisme au sein des revues intellectuelles de l’immédiat après-guerre et d’une étude de la trajectoire idéologique d’un intellectuel particulier, Gérard Genette, au sein de l’espace des revues militantes, cette communication analyse le cas particulier de la revue Socialisme ou barbarie dans une double perspective d’analyse du discours et de philosophie politique. Notre hypothèse serait la suivante : les revues favoriseraient, par leur matérialité discursive et éditoriale, l’émergence de débats idéologiques plus ou moins polémiques et oppositionnels autour du marxisme. En replaçant la création de ces revues dans leur contexte socio-discursif, nous entendons interroger la manière dont les textes de présentation singularisent, tout en les reproduisant, un interdiscours et une socialité bien précis. Si l’étude des articles parus dans Les Temps Modernes et Critique de mai à décembre 1946 a pu mettre en relation une obsession discursive quant aux marxismes orthodoxes et hétérodoxes et à la montée historique du P.C.F., le contexte de création de Socialisme ou barbarie (1949) nous obligera à tenir compte d’événements politiques et culturels divers (Guerre froide, constitution des deux Allemagnes, création de la revue La Table ronde, parution d’articles consacrés aux évolutions politiques et idéologiques dans Les Temps Modernes, Critique et Esprit, Traité de Londres, création de la République Populaire de Chine, centenaire du Manifeste du parti communiste, etc.). Notre communication se concentrera plus particulièrement sur le texte de présentation de la revue dans ce qu’il dit d’une historicité discursive et idéologique précise. Les textes de positionnement et de repositionnement des revues permettent en effet de dégager un ensemble d’enjeux et de tensions à l’oeuvre au sein de la communauté intellectuelle. Leur caractère plus ou moins affirmatif, parfois à la limite du pamphlétaire, entraîne une série de traits rhétoriques significatifs (attaques ad hominem, questions rhétoriques, allo-attributions, registre polémique, vocabulaire de l’attaque-défense, ironie, etc.), traduisant des positions idéologiques, qu’il sera nécessaire d’analyser dans le premier texte de la revue de Castoriadis et Lefort. L’attention portée aux thématiques marxistes se justifie par la véritable croissance des discours à ce propos dans l’immédiat après-guerre et par le besoin réel qu’éprouvent les intellectuels français de se positionner par rapport au P.C.F. et aux autres mouvances marxistes. Un rapport particulier se crée dès lors entre le savoir et une certaine temporalité que le genre de la revue met en oeuvre au travers de son éclatement et de sa périodicité. En effet, par la transmission d’un état des travaux non abouti et par l’urgence de sa situation sociale, il permet de saisir sur le vif un savoir en cours d’élaboration, constituant ainsi une forme de « mémoire immédiate » faisant état d’une histoire des idées collectives. Le rythme des publications, les stratégies de positionnement idéologique, la circulation des concepts et la nécessité de répondre aux besoins des lecteurs rendent ces savoirs intrinsèquement dynamiques et critiques, dans une constante interaction entre le monde social et les idées qui le façonnent. Comme le note Yves Peyré, dans Les Revues littéraires au XXe siècle, on trouve, d’une part, un « acte militant à la racine même de la revue » et, d’autre part, la réponse à un besoin de mettre en scène, par une polyphonie de voix, un dialogue agissant sur la réalité sociale et se construisant par le profit de débats, de dissonances et de dissensions internes et externes.

The loose condition of "autism" is undergoing through a broad process of (re)definition under the aegis of genomic medicine, which promises to find (epi)genetic causes to autism, or at least to some forms of the Autism Spectrum Disorder. What is at stake is a scientific controversy about the very definition of the condition, i.e. the diagnosis itself. Whether it is considered primarily as a psychopathology or as a genetic disorder has consequences. It has implications regarding who would have the authority to diagnose the condition but also about the ways of taking care of persons with autism. In this paper, we depart from the paradox that some patients' organizations claim for a "geneticization" of the condition, so as to get rid of any sort of "psy-" related dimensions. It seems paradoxical because if the causes of autism are to be found in the genes, and hereby partly determined, it would seem to imply that the margins for effective therapy are narrowing down. We want to test the hypothesis that the more objective, "naturalized" a diagnosis is, the more it opens up possibilities for broadening the therapeutic reach outside the autist bodies, questioning the "milieu" of the disorder — the environment through which it is produced and the wealth of linkages and relationships through which living with autism could be eased. In other words, stressing that the diagnosis is a site to explore these contested dimensions of autism, its "geneticization" could lead to more active uptakes in patients care, whereas blurry diagnosis could not afford a similar reach. Following a pragmatic stance of an "art of consequences" (I. Stengers), we investigate the tensions raised by a genetic diagnosis which tends to "objectify" or "naturalize" the causes of the condition with respect to the lived experiences of persones with autism and their relatives, following some of the contested dimensions of a "politics of diagnosis" in their effects on affected autistic bodies and minds. To unfold those issues, our ongoing inquiry considers the interactions between various persons and institutions involved in the debate in Belgium. [less ▲]

Caryl Phillips's oeuvre has a social and political agenda: to give a voice to those who were forgotten by history and to make their story resonate through time and space. The musicalization of his writing seems to be a way to achieve this ambitious goal. My paper will be devoted to Phillips’s novel The Nature of Blood, in which music is present both thematically (with an explicit reference to Louis Armstrong and scenes of dancing) and formally. I will mostly explore the formal aspect by addressing the techniques with which Phillips musicalizes his literary text. In order to do so, I will rely upon Emily Petermann’s The Musical Novel: Imitation of Musical Structure, Performance, and Reception in Contemporary Fiction [2014]. In this monograph, she defines three different ways of imitating jazz music: sonic effects in prose (alliteration, rhyme, meter), structural patterns (the riff, the Call-and-Response pattern, chorus) and the performance situation (imitating orality, improvisation, use of repeated lexical items). All these features are present in Phillips’s novel. [less ▲]

In Europe, certification of the fire resistance of building construction elements can be assessed by experimental testing or by calculation. To date, both communities (testing and calculation) express the fire resistance results in a deterministic way, i.e. each fire resistance result consists in a single number as if there was no uncertainty. However, when asking different partners within a community to assess the fire resistance of a given element of building construction subjected to a given fire scenario (a so-called “round robin” exercise), the reported results exhibit a very significant variability. Recent efforts have been undertaken to evaluate the extent of the scatter for fire resistance results, i.e. a process of "uncertainty evaluation". This process recognizes the fact that, for a given element of building construction and a given fire scenario, only a probability distribution (as opposite to a deterministic value) can be attributed to the fire resistance result. This approach opens the door to probabilistic reporting as an alternative to deterministic one. [less ▲]

After a fire in a building, questions arise regarding the post-fire fire capacity of the structure. Assessment of post-fire capacity of structural elements should consider the residual safety level which, in the absence of codification, requires performing a full probabilistic analysis. Therefore, an easy-to-use method is presented which allows to make a probabilistic calculation, using only analytical formulas and a pre-calculated graph. The method is applied to a real case study, consisting of a fire that took place in an apartment building in Belgium, indicating sufficient load bearing capacity for further use. [less ▲]

This paper presents a computationally-effective macro element for predicting the complete shear response of RC deep beams. The element stems from a three-parameter kinematic theory (3PKT) for the shear strength and deformation capacity of deep beams under double curvature. The macro element consists of two rotational springs and one transverse spring to simulate the nonlinear flexural and shear behaviour of deep shear spans. The element is applied to two deep beams tested to shear failure under three-point bending. The results are used to study the effect of unsymmetrical shear failures on the pre- and post-peak behaviour of nominally symmetrical members. It is found that the post-peak response is sensitive to the unloading path of the shear resisting mechanisms as well as to the global roughness of the critical diagonal cracks. Based on these analyses, modifications to the constitutive relationships of the shear mechanisms are proposed, and the macro element is applied to a continuous deep beam. It is shown that the model adequately captures the complete behaviour of the beam, including the redistribution of forces following the shear failure in the critical shear span. [less ▲]

Les responsables des formations à la Médecine générale et de famille (MG/MF) des trois universités francophones de Wallonie et Bruxelles souhaitent prévoir la conservation et l’édition online des Travaux de Fin d’Etude (TFE) des Internes en formation. Assembler et publier un grand nombre de travaux montera la force et l’importance du travail fourni par les Internes. La mise à disposition publique nécessite donc un système d’indexation adéquat à la pratique de la MG/MFi. Il s’agit ici de littérature dite « grise » mais dont l’importance ne doit pas être méconnueii En bibliographie usuelle, les publications sont généralement indexées par les Medical subject Heading (MeSH) de la National Library of Medicineiii. Toutefois, il n’est pas aisé de standardiser l’indexation au départ d’une liste de plus de 25.000 MeSH non prévu spécifiquement pour l’exercice de la MG/MF. Dans le cadre de sa thèse de doctorat en médecine générale et de famille (ULg, Prof. Vanmeerbeek), l’auteur a développé un tel système d’indexation. Une nouvelle classification des items non-cliniques, développées sous le nom de Q-Codes a été élaboréeiv. Elle est associée à la Classification Internationale des soins Primaires, deuxième édition (CISP-2). Ces deux outils forment ensemble un instrument de catégorisation de l’activité et des publications en MG/MF. Il est connu sous l’acronyme 3CGP, ou Core Content Classification in GP/FM.v 3CGP offre moins de 900 codes. [less ▲]

e probability of perceiving two objects as being similar is a negative exponential function of the distance between them in an internal psychological space (Shepard 1987). Our experimental studies showed that this distance and hence the similarity between objects in the same category is modulated by their size, frequency, and manipulability. Our experimental work also revealed that object properties evoked by digit-word expressions modulate numerosity estimations such that “8 elephants” were judged to be more numerous than “8 ants”, for instance. ese ndings extend the literature on human perceptual biases (Binet 1890) by showing that words instantly access rich mental representations. Our latest experimental ndings established that various emotional states signi cantly impact measurement estimations. [less ▲]

The demethylating agent 5-azacytidine (AZA) has proven its efficacy as treatment for myelodysplastic syndrome and acute myeloid leukemia. In addition, AZA can demethylate FOXP3 intron 1 (FOXP3i1) leading to the generation of regulatory T cells (Treg). Here, we investigated the impact of AZA on xenogeneic graft-versus-host disease (xGVHD) and graft-versus-leukemia effects in a humanized murine model of transplantation (human PBMCs-infused NSG mice), and described the impact of the drug on human T cells in vivo. We observed that AZA improved both survival and xGVHD scores. Further, AZA significantly decreased human T-cell proliferation as well as IFN-γ and TNF-α serum levels, and reduced the expression of GRANZYME B and PERFORIN 1 by cytotoxic T cells. In addition, AZA significantly increased Treg frequency through hypomethylation of FOXP3i1 as well as increased Treg proliferation. The later was subsequent to higher STAT5 signaling in Treg from AZA-treated mice, which resulted from higher IL-2 secretion by conventional T cells from AZA-treated mice itself secondary to demethylation of the IL-2 gene promoter by AZA. Importantly, Tregs harvested from AZA-treated mice were suppressive and stable over time since they persisted at high frequency in secondary transplant experiments. Finally, graft-versus-leukemia effects (assessed by growth inhibition of THP-1 cells, transfected to express the luciferase gene) were not abrogated by AZA. In summary, our data demonstrate that AZA prevents xGVHD without abrogating graft-versus-leukemia effects. These findings could serve of basis for further studies of GVHD prevention by AZA in acute myeloid leukemia patients offered an allogeneic transplantation. [less ▲]

José Muñoz and Carlos Sampayo’s Constancio y Manolo (1976) is their seventh story featuring New York-based detective Alack Sinner. It depicts a Spanish family whose patriarch fought for the Republicans during the Civil War. It also mentions events that took place when Constancio y Manolo was being made: the US presidential election, the death of Francisco Franco and the consequent fall of Spanish dictatorship, and, albeit implicitly, the rise of a similar military, theocratic, and violent regime in the cartoonists’ native country, Argentina. The graphic style is heterogeneous, the main plot is fragmentary and numerous secondary stories interfere with its development; and yet, we are paradoxically dealing with a highlycoherent work. Muñoz and Sampayo’s poetics of fragments are put in the service of their own worldview, committed to resist against all mechanisms of oppression and expressing a deep empathy for all those left out of “economic progress”.

Le facteur kurde dans les conflits au Moyen-Orient.. Résumé, L’objectif principal de cette communication est de montrer les enjeux politiques et sécuritaires de l’implication des Kurdes dans les conflits au Proche et au Moyen-Orient. La participation des Kurdes à la résistance à l’État islamique et leur rôle déterminant dans le conflit en Irak et en Syrie ont fortement augmenté leur poids politique. Depuis le déclenchement du conflit en Syrie la question kurde est devenue un sujet de préoccupation pour certains pays de la région qui ont peur des conséquences de la naissance d’une entité fédérale dans le Nord de la Syrie. Ceci crée un dilemme de sécurité pour la Turquie et l’Iran qui ont des convergences d’intérêt sur la question kurde. C’est pourquoi nous constatons depuis quelques mois l’intensification de la guerre entre le PKK et la Turquie et l’entrée de l’armée turque dans le Nord de la Syrie, à quoi il faut ajouter la reprise de la lutte armée du PDKI dans le Kurdistan iranien. Ce qui montre le caractère transfrontalier du facteur kurde au Moyen-Orient [less ▲]
