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.

The physical education teacher is considered as a cornerstone of the physical activity promotion in the schools. This presentation proposes answers to three questions: (1) Why to promote physical activity at school? (2) Why the PE teacher should play a central role? (3) How the PE teacher could play such role? In conclusion, it is important to remember that (1) PE teachers should become the cornerstones of the PA promotion at school; (2) They have to be involved in PE as well as in the other dimension of PA at school; (3) They have to collaborate (they are not alone), and; (4) Pre service and inservice PETE has to be adapted to show the way and change the mentalities [less ▲]

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).
