    In this panel session, citizen science practitioners, researchers, and facilitators share their unique responses to the question What is good citizen science, for whom, and why?, with the aim of informing and developing citizen science theory and practice

    Flanders Ahead, Wallonia Behind (But Catching up): Reconstructing Communities Through Science, Technology and Innovation Policymaking

    Drawing on a documentary analysis of two socio-economic policy programs, one Flemish (“Vlaanderen In Actie”), the other Walloon (“Marshall Plans”), and a discourse analysis of how these programs are received in one Flemish and one Francophone quality newspaper, this article illustrates how Flanders and Wallonia both seek to become top- performing knowledge-based economies (KBEs). The paper discerns a number of discursive repertoires, such as “Catching up,” which policy actors draw on to legitimize or question the transformation of Flanders and Wallonia into KBEs. The “Catching up” repertoire places Flanders resolutely ahead of Wallonia in the global race towards knowledge, excellence, and growth, but suggests that Wallonia may, in due course, overtake Flanders as a top competitive region. Given the expectations and fears that “Catching up” evokes among Flemish and Walloon policy actors, the repertoire serves these actors as a flexible discursive resource to make sense of, and shape, their collective futures and their regional identities. The article’s findings underline the simultaneity of, and the interplay between, globalizing forces and particularizing tendencies, as Flanders and Wallonia develop with a global KBE in region-specific ways

    An experimental realisation of steady spanwise forcing for turbulent drag reduction

    Full text link
    We present an experimental realisation of spatial spanwise forcing in a turbulent boundary layer flow, aimed at reducing the frictional drag. The forcing is achieved by a series of spanwise running belts, running in alternating spanwise direction, thereby generating a steady spatial square-wave forcing. Stereoscopic particle image velocimetry is used to investigate the impact of actuation on the flow in terms of turbulence statistics, performance characteristics, and spanwise velocity profiles, for a waveform of λx+=401\lambda_x^+ = 401. An extension of the classical spatial Stokes layer theory is proposed based on the linear superposition of Fourier modes to describe the non-sinusoidal boundary condition. The experimentally obtained spanwise profiles show good agreement with the extended theoretical model. In line with reported numerical studies, we confirm that a significant flow control effect can be realised with this type of forcing. The results reveal a maximum drag reduction of 26% and a maximum net power savings of 8%. In view of the limited spatial extent of the actuation surface in the current setup, the drag reduction is expected to increase further as a result of its streamwise transient. The second-order turbulence statistics are attenuated up to a wall-normal height of y+100y^+ \approx 100, with a maximum streamwise stress reduction of 44% and a reduction of integral turbulence kinetic energy production of 39%

    An RRI for the Present Moment: Relational and ‘well-up’ innovation

    The ultimate framing of the first iteration of RRI as enabling smart, inclusive, sustainable growth had as much to do with the financial crisis then engulfing the Eurozone as meeting the goals of the Lisbon Treaty. Now we have come to the end of Horizon 2020, it is presently unclear how RRI will continue to be addressed as it is mainstreamed into Horizon Europe. In this Perspective, we will argue that discussions about placing responsibility at the centre of innovation should not solely be aimed at promoting GDP-measured growth. Our vision must be longer, more global, more transformative. In this short piece, we explore the possibilities arising through extending ‘responsibility’ to an a-growth approach to innovation, one which emphasises the relational dimensions of responsible innovation through the concept of ‘well up’ economics
