La presse du XIXe siècle est attentive à instaurer un dialogue régulier et diversifié avec son lectorat, qui s’étend au fil du siècle à de nouvelles personnes : ouvrier, femmes, enfants. Or, la plupart du temps, ces voix et figures de lecteurs en journal sont fabriquées de toutes pièces : faux profils, rubriques convenues, individualisation artificielle d’une catégorie de destinataires, confusion entre les récepteurs et l’équipe de rédaction, etc. Les procédés varient entre les journaux qui donnent à voir des lettres de lecteurs, ceux qui exhibent l’interlocution elle-même et ceux qui jouent avec les discours supposés du lectorat. Ce dernier procédé conduit à examiner dans quelle mesure l’équipe de rédaction du journal se constitue, s’autodéfinit et se conforte à travers une rhétorique et une pragmatique concertées de la mention du lectorat : il s’agirait moins de donner la parole que de feindre de le faire, pour mieux s’exprimer dans l’entre-soi de l’espace déjà socialisé de la communication médiatique. Ce phénomène pose aussi la question d’une réception ressaisie à travers la textualité du journal et modulable par l’instance collective de production. Enfin, en créant son lectorat autant sinon davantage qu’il le désigne, le journal introduit de la médiation dans un discours adressé et, ce faisant, poétise les figures de destinataires et produit des effets de littérarité. On peut examiner la constitution des profils de lecteurs dans plusieurs périodiques de l’époque pour apporter des éléments de réponse à ces questions : - que nous apprennent ces stratégies discursives à propos de la collectivité du journal, attentive à programmer sa réception ? - dans quelle mesure les communautés médiatiques peuvent-elles véritablement accueillir le dialogue avec leurs lecteurs ? - y a-t-il des différences significatives entre petite et grande presses, la première étant certes davantage portée sur les logiques ludique et autoréférentielle, mais fonctionnant surtout en effectifs restreints dans sa production et sa réception ?

The project consists in investigating the role of the Belgian dynasty in scientific development since the beginning of the reign of king Albert I (1909), until the establishment of the National Council for Science Policy (CNPS) in 1959, during king Baudouin's reign, following the publication of the work of the "National Commission on Science" which released its conclusions in the same year. The study deals with the action of the sovereign and the networks he formed with his entourage (the queen, the crown prince, the advisers of the court, some close relations of the king, the ministers in charge of scientific affairs) in the field of science, along various research themes; how these people saw the role of science in society; what influence they had in the development of science (institutions, initiatives, projects); what relationships existed between the dynasty and the scientific institutions; what the relationships between the dynasty and the Congo were in the realm of science. This perspective, which focuses on three Belgian sovereigns of the twentieth century, should make it possible to assess the development and progressive implementation of the "science policy". To date, no study has been specifically devoted to this topic. [less ▲]

Chair: François Ladame (Swiss Soc) Presentations: Anders Carlberg (Swedish Assoc) / Sara Flanders (British Soc) / Petra Heymanns (German Assoc) / Despina Naziri (Belgian Soc) / Denny Panitz (Hellenic Soc) The EPF ad-hoc group on homosexuality (Anders Carlberg (Swedish Assoc.), Sara Flanders (British Soc.), Petra Heymanns (German Assoc.), François Ladame (Swiss Soc.), Despina Naziri (Belgian Soc.), and Denny Panitz (Hellenic Soc.)) will present the result of their thorough exploration of what Freud did say and didn’t say about homosexuality. To get there, we first did a chronological – and hopefully comprehensive – review of Freud’s writings on the issue. On a second step, we gathered the quotations according to a number of themes: bisexuality, narcissism, development, aggression and conflict, identification and Oedipus, and perversion/inversion. For the panel, the presentation on Freud’s thinking on homosexuality shall be organised around four “dimensions”: bisexuality, object choice, normality/pathology, and the quantitative factor, with a few “variables” impacting in various ways on each of them (narcissism, free aggressiveness, the socio-cultural context, and the historical meaning of perversion). Due consideration will also be given to the general theme of the Conference “too much – not enough”. As our results are questioning and challenging, enough time shall be kept for the discussion with the floor. [less ▲]

Developed by a European consortium led by the Centre Spatial de Liège in Belgium, the Extreme Ultraviolet Imager (EUI) is an instrument onboard the Solar Orbiter ESA M-class mission. At its 0.28AU perihelion, the spacecraft will be exposed to a 13 solar constants solar flux. EUI is protected behind the spacecraft heat shield but for three apertures for its telescopes looking at the Sun in the Extreme-UV. To better reject the unwanted visible light and protect 150nm thick EUV filters, Aluminum coated carbon-fiber-reinforced plastics entrance baffles are located at the front of the instrument. The residual absorbed heat by the entrance filters and baffles is evacuated through heat pipes to a dedicated spacecraft thermal interface. To verify its thermal design, the instrument structural and thermal model has been tested in a vacuum chamber with a solar simulator providing the 13 solar constants solar flux at the three entrance apertures and dedicated heaters to model the spacecraft heat shield feedthroughs. To assess the off-pointing performance of the entrance baffles, the instrument was mounted onto a rotating structure inside the chamber. The test setup, results and the thermal model correlation will be presented as well as the calibration of the solar simulator divergence and intensity. [less ▲]

Measurement and use of stable isotope ratios have a long history at the University of Liege (Belgium). Since at least 30 years, applications of stable isotopes in marine ecosystems have been developed within the Laboratory of Oceanology and, more recently, within the Chemical Oceanography Unit. In the Laboratory of Oceanology, one research axis is the measurement of stable isotope composition (C, N, S) in organic matter to delineate trophic web structure and to study animal diet, their trophic niches and their alteration by human activities. This methodology has been successively applied worldwide in different habitats and ecosystems (marine, freshwater, terrestrial) in temperate and tropical areas. Mediterranean food web and fish trophic ecology have received a particular attention. Coupling between trophic ecology and ecotoxicology is another area of investigation. This has been applied mainly to marine vertebrates and freshwater ecosystems. Stable isotope labelling is also used in our laboratory to study and quantify various ecological processes such as inorganic nitrogen incorporation and trophic transfers. The laboratory facilities, renewed in 2012 and managed by Dr. Gilles Lepoint, are composed of an elemental analyser (EA, vario MICRO cube, Elementar) and a gas chromatography (GC, Agilent) coupled to an isotope ratio mass spectrometer (IRMS, Isoprime 100). The GC is also equipped with a quadrupole mass spectrometer. In 2014, the Chemical Oceanography Unit, headed by Dr. Alberto Borges, has acquired and implemented an off-axis cavity ring-down spectroscopy (CRDS) for the measurements of δ15Nα, δ15Nβ, δ18O of N2O. This enables characterization of the N2O origin in a variety of aquatic environments including groundwater in Wallonia, rivers and lakes in Wallonia and Africa, coastal environments (Scheldt estuary, Lake Grevelingen, North Sea), Mediterranean seagrass beds, and Antarctic and Arctic sea-ice.

Polyspecific seagrass meadows are ubiquitous features of tropical coastal zones. These ecosystems are of critical ecological importance, and provide a wide range of socio-economical services to local populations. Meadows however undergo multiple threats linked to human activities (increased nutrient input, overfishing, invertebrate overharvesting, etc.). It is currently hard to assess how seagrass meadows could respond to anthropogenic impacts due to poor knowledge of their functional ecology. In an effort to unravel trophic interactions ruling the food webs associated to seagrass beds of the Toliara Great Reef (SW Madagascar), we studied resource segregation between two common Diogenidae hermit crabs (Dardanus scutellatus and Ciliopagurus tricolor) using stable isotope ratios. C, N and S stable isotope ratios of bulk muscle tissue were measured via CF-EA-IRMS (Elementar Vario MicroCube EA coupled to an Isoprime 100 MS). Interspecific differences were noted in isotopic composition of carbon (δ13C = -12.22 ± 1.73 ‰ for D. scutellatus, δ13C = -14.55 ± 0.73 ‰ for C. tricolor), nitrogen (δ15N = 4.73 ± 0.53 ‰ for D. scutellatus, δ15N = 5.20 ± 0.61 ‰ for C. tricolor) and sulfur (δ34S = 14.08 ± 2.32 ‰ for D. scutellatus, δ34S = 16.73 ± 1.49 ‰ for C. tricolor), suggesting that the two species do not feed on the same items. In addition, SIBER (Stable Isotope Bayesian Ellipses in R) modeling based on C and N data clearly showed that no overlap was present in the core isotopic niches of the two species. It also indicated that the isotopic niche of D. scutellatus was greater than the one of C. tricolor, implying that the former feeds on a greater number of items than the latter. While hermit crabs are generally considered as omnivorous species, this study highlighted differences in the foraging ecology of D. scutellatus and C. tricolor. These differences could help to limit competition for food between these two species, and facilitate their coexistence in Malagasy seagrass beds. [less ▲]
