In the space of just a few years the concept of Responsible Research and Innovation (RRI), or in Dutch Maatschappelijk verantwoord innoveren (MVI), has gained considerable ground: NWO has an MVI-program that has so far funded three rounds of research proposals; Horizon 2020 regularly refers to RRI; and there is now a new journal devoted to RRI. In this panel we focus on the following questions: • How could the concept become so popular in such a relatively short time? • What, if anything, is new in RRI, when we compare it to e.g. CTA, participatory TA, Public Engagement, etc? • If we want to make research and innovation more responsible and responsive to society’s needs, what are the opportunities and obstacles? • What are the conditions for successful mainstreaming of RRI? Panel members Frank Kupper (Athena Institute) Hub Zwart (Centre for Society and the Life Scences), Michiel van Oudheusden (author of a dissertation on Flemish RRI initiatives), and Tsjalling Swierstra (co-founder of the Journal for RI) share their thoughts with colleagues in the audience.

The outcome of the interaction between the solar wind and the Jovian magnetic field bears many differences compared to the Earth's case. At Earth, the solar wind is the major particle and energy source in the magnetosphere. At Jupiter, the tremendous volcanism on the moon Io is the main plasma source and Jupiter's rapid rotation (relative to its size) is the main energy source for the particles populating its magnetosphere. Combined with a weaker solar wind pressure and a larger Alfvén Mach number as the distance from the Sun increases, all these parameters modify the relative importance of large scale Dungey reconnection and viscous interaction at the magnetopause. In order to study these differences, here we present a statistical analysis of magnetopause waves and flux tube event on the Jovian magnetopause, based on in-situ measurement from the spacecraft that flew-by or orbited around Jupiter. Moreover, variations of the solar wind have significant impact on the Jovian magnetospheric current systems and such changes reflect on the aurora. In this presentation, we will also review the recent findings concerning the aurora at Jupiter and their relationship with the solar wind. [less ▲]

The ionosphere has always been a major limitation for GNSS positioning applications. Free electrons in the ionosphere perturb the propagation of GNSS radio signals involving both refraction and diffraction effects. In particular, small-scale ionospheric irregularities generated by different physical processes may cause scattering effects on GNSS signals, producing rapid fluctuations of the signal phase and amplitude as a result. Such scintillations of GNSS signals are responsible for critical consequences regarding applications, such as precise positioning, due to many resulting effects: cycle slips, signal power fading, receiver loss of lock and poor resulting satellite geometry. Ionospheric Scintillation Monitoring Receivers collect high-rate GNSS data. Specific scintillation parameters, such as the well-known S4 and Phi60 indices, are built on high-rate measurements performed on GNSS signals and provide additional information to characterize the intensity of such an event occurring at a specific geographic location at a given time. Spatial Statistics belong to the field of Spatial Analysis, Geography and GIS (Geographic Information System). This discipline allows to perform analyses of data which are localised in space. Ionospheric Scintillation observations achieved by ISMR stations can be characterized by a set of attributes (S4, Phi60, Rate of TEC, etc.) including also the geographic location of their respective Ionospheric Pierce Point (IPP). By combining the simultaneous Multi-GNSS ISMR measurements from a network of ISMR stations, we can obtain a spatially denser data set, able to support spatial statistics tests. The idea of our research is to provide a spatio-temporal analysis of ionospheric scintillation events over Equatorial regions by applying spatial statistics on ISMR Multi-GNSS measurements. In particular, by using spatial statistics, we aim to resolve specific issues regarding ionospheric scintillation data from an ISMR network established in Brazil. The research consists in spatially describing the data set, detecting and measuring potential spatial autocorrelation, determining the scale of the spatial dependency and finally producing an interpolated scintillation sky map at a given time. In terms of applicability of the methodology, our research project consists in exploiting the spatio-temporal analysis performed on ionospheric scintillation data in order to improve the performances and the reliability of Absolute GNSS Positioning algorithms under moderate ionospheric scintillation conditions. By assessing correlations existing between specific ISMR data and classic GNSS observations, the method could be extended to a more general usage which would be independent of ISMR measurements.

This powerpoint presentation was used as teaching material in a seminar given as part of the course “Compléments de fabrication mécanique et FAO” at Université catholique de Louvain. It outlines important current issues in the developments of additive technologies for the processing of metallic materials by discussing two case studies from researches carried out by the Metallic Materials Science Unit (ULg). In particular, two different metallic alloys, i.e. stainless steel 316L and Ti-6Al-4V, have been processed by laser beam melting under similar conditions, and their microstructures and mechanical behaviours have been compared in details. Under the investigated conditions, Ti-6Al-4V exhibits a more complex behaviour than stainless steel 316L with respect to the occurrence of microstructural and mechanical anisotropy. Moreover, Ti-6Al-4V appears more sensitive to the build-up of internal stresses when compared with stainless steel 316L, whereas stainless steel 316L appears more prone to the formation of “lack of melting” defects. This correlates nicely with the difference in thermal conductivity between the two materials. Thermal conductivity was also shown to increase strongly with increasing temperature. [less ▲]

Models with reciprocal inhibition are ubiquitous in the literature. For instance, common rhythmic motor behaviors produced by central pattern generators (CPGs) involve half-center oscillators, which consist of two inhibitory neurons that are not endogenous oscillators, but produce rhythmic outputs when reciprocally connected (Marder & Calabrese 1996). Models of thalamocortical spindle oscillations also suggest that the rhythm originates from the thalamic reticular nucleus, which consists in interacting inhibitory nonoscillatory neurons (Wang & Rinzel 1992).

Durch die Artikel 32-34 des Versailler Vertrags wurden die beiden deutschen Grenzkreise Eupen und Malmedy nach einer umstrittenen Volksbefragung im Jahr 1920 Belgien zugeschlagen. Dabei wies der Kreis Malmedy eine Besonderheit auf: er war zwei- bzw. dreisprachig Deutsch-Wallonisch-Französisch. Tatsächlich waren rund 10.000 Wallonen seit den Entscheidungen des Wiener Kongresses von 1815 Bürger Preußens und später des Kaiserreichs gewesen. Der Beitrag fragt nach ihrer Identität im Kaiserreich, wo sie zu Kollateralopfern der gegen größere Minderheiten gerichteten Germanisierungspolitik wurden, woraus ein wallonischer Kulturpartikularismus an der deutsch-belgischen Grenze resultierte. Dabei wird auch deren Offenheit während des langen 19. Jahrhunderts deutlich, die durch intensive grenzüberschreitende soziale, wirtschaftliche und auch kulturelle Kontakte gekennzeichnet ist. Der Beginn des Ersten Weltkriegs wurde deshalb als umso dramatischer empfunden. Die Haltung der Bevölkerung in der so genannten Preußischen Wallonie während des Kriegs ist jedoch bisher von der Forschung kaum in den Blick genommen worden. Deutlich lässt sich jedoch der Einfluss eines sich nunmehr erheblich beschleunigenden Nationalisierungsprozesses an der Grenze zum besetzten Belgien ausmachen. Auf der Grundlage der im Staatsarchiv Eupen erhaltenen Bestände des Kreisarchivs Malmedy im Kreis sollen die Auswirkungen des Krieges auf die kleinste Minderheit im Westen dargestellt werden. Gefragt werden soll nach Misstrauensbekundungen „von oben“, nach potentiellen Loyalitätskonflikten, z.B. in Form von Desertionen, ggf. nach Nachkriegsvorstellungen der Betroffenen und nach einem Wandel von Zugehörigkeitsgefühlen. Besonderes Augenmerk wird dabei auf jene (überaus seltenen) Akteure gelegt, die schon vor 1914 einen Anschluss des Gebietes an Belgien gefordert hatten und die sich der besonderen Aufmerksamkeit der preußischen Behörden gewiss sein konnten. Kaum zu überschätzen ist auch die Bedeutung der Pfarrer, die in einer als streng katholisch geltenden Region erheblichen Einfluss auf das politisch-gesellschaftliche Leben und – selbstverständlich – auf die Trauerarbeit für gefallene Soldaten (deren Zahl sich auf einige Hundert beläuft) nahmen. Nicht zuletzt stellt sich die Frage nach der Erfahrung des Kriegsendes und der darauf folgenden Besatzungszeit durch britische Truppen, die im August 1919 von belgischen Soldaten abgelöst wurden. Diese Fragen sind bisher, so sie denn überhaupt gestellt worden sind, zumeist aus der Perspektive des Staatenwechsels von 1920 beantwortet worden. Der Kampf einiger Akteure für die Behauptung einer wallonischen Identität innerhalb des Kaiserreichs wurde in der belgisch-nationalen Historiographie zu einem Kampf für die Eingliederung durch Belgien umgedeutet, die Zugehörigkeit zu Preußen zum dark age der lokalen Vergangenheit erklärt – wobei die Zugehörigkeit zur französisch-wallonischen Sprachgemeinschaft hier eine andere Ausgangslage schaffte als für ebenfalls an Belgien abgetretenen deutschsprachigen Gemeinden um die Städte Eupen und St. Vith. Diese Narrative entfalteten ihre durchschlagende Wirkung jedoch erst nach dem Zweiten Weltkrieg und der 1940 erfolgten Wiedereingliederung Eupen-Malmedys durch das „Großdeutsche Reich“. Der Beitrag unternimmt den Versuch, die Entwicklung der Jahre 1914-1920 nicht von ihrem Ende her zu betrachten, wobei der – bisher vernachlässigten – erfahrungsgeschichtlichen Perspektive besondere Bedeutung zukommt. Insofern zielt er ebenfalls darauf ab, die Grenzgeschichte aus der Zentrum-Peripherie-Perspektive zu lösen und – auch sehr kleine – Grenzregionen als Akteur (und nicht als bloßes Objekt) zu fassen.

Les familles recomposées font face à de multiples transitions.Au cœur de ces transitions, différents processus de redéfinition interactionnelle et mythique sont attendus. Parmi ceux-ci, la construction des nouvelles appartenances qui prévoit la gestion des ruptures ainsi que la construction de nouveaux repères affectifs et sociaux. Dans la pratique psychothérapeutique, nous rencontrons souvent des couples et des familles qui ont « mal » aux transitions et qui se proposent comme « suspendues » entre un passé non reproductible et un futur imperceptible. A travers des situations cliniques et de recherche avec des familles recomposées, l’intervention portera sur l’intérêt d’aborder ces transitions complexes à travers le concept de perte ambiguë. Ce travail prévoit, non pas tant une élaboration définitive des précédentes appartenances mais bien une co-création de ponts affectifs entre le passé et le présent, l’écriture de nouveaux scripts pour le futur ainsi que la gestion d’appartenances multiples et ce, également à travers la re-dynamisation de ressources et de potentialités évolutives chez les couples, familles et leurs réseaux.

The study of procedural learning abilities in children with Specific Language Impairment (Procedural Deficit Hypothesis, PDH; Ullman & Pierpont, 2005) remains a relatively unexplored field of research. Since most evidence comes from studies using tasks which involve learning of sequenced patterns, research using other procedural learning paradigms (like motor adaptation tasks) is needed to further evaluate the PDH in children with Specific Language Impairment (SLI). Therefore, in this study, we examined the ability of children with and without SLI to learn, consolidate and generalize a mirror-tracing task, a paradigm that does not involve sequence learning and had never been used in SLI. Children with SLI and typical developing (TD) matched children participated in the study. Children with SLI were included if they scored below -1.25 SD of the expected normative performance in at least 2 language areas. Both groups had to trace ten 5-pointed stars seen only in mirror-reversed view in two learning sessions separated by a one-week delay. The transfer phase consisted in tracing a new figure. The time required to complete the tracing, and the number of errors committed were recorded. Full results will be presented and discussed during the presentation of the paper. [less ▲]
