    Construction and Validation of ‘Science Culture Index’

    Get PDF
    Countries world-wide routinely collate statistics on STS performance indicators such as R&D expenditure, science publications, citations and impact, high-tech employment, and penetration of hightech goods. In parallel there have been several, but often isolated, attempts to define complementary public understanding of science (PUS) indicators including concepts such as scientific literacy, public sentiment, interest, and attitudes. This has been somewhat successful, but also controversial. Thus, little progress has been achieved to explicitly combine STS performance indicators and PUS indicators in a composite index of science culture. This exercise draws conceptual and methodological material used in the construction of such a composite index based on a combined data base of EU (32 countries) and India (23 States). On the basis of these 55 state units the theoretical basis, feasibility and validity of a globally portable index of science culture is demonstrated. Details of the analytical options considered and decisions made, particularly in regard to integration of two data sets, identifying and defining indicators, constructing composite indices and finally its validation has been discussed. The discussion inevitably involves a degree of EU-India specific analyses, however, the methodological issues and suggested solutions are of broader interest to researchers on the topic in other contexts.science culture, EU, India, public understanding of science, STS, indicators

    Sobolev metrics on shape space of surfaces

    Let MM and NN be connected manifolds without boundary with dim(M)<dim(N)\dim(M) < \dim(N), and let MM compact. Then shape space in this work is either the manifold of submanifolds of NN that are diffeomorphic to MM, or the orbifold of unparametrized immersions of MM in NN. We investigate the Sobolev Riemannian metrics on shape space: These are induced by metrics of the following form on the space of immersions: G^P_f(h,k) = \int_{M} \g(P^f h, k)\, \vol(f^*\g) where \g is some fixed metric on NN, f^*\g is the induced metric on MM, h,kΓ(fTN)h,k \in \Gamma(f^*TN) are tangent vectors at ff to the space of embeddings or immersions, and PfP^f is a positive, selfadjoint, bijective scalar pseudo differential operator of order 2p2p depending smoothly on ff. We consider later specifically the operator Pf=1+AΔpP^f=1 + A\Delta^p, where Δ\Delta is the Bochner-Laplacian on MM induced by the metric fgˉf^*\bar g. For these metrics we compute the geodesic equations both on the space of immersions and on shape space, and also the conserved momenta arising from the obvious symmetries. We also show that the geodesic equation is well-posed on spaces of immersions, and also on diffeomorphism groups. We give examples of numerical solutions.Comment: 52 pages, final version as it will appea

    New report for the European Commission identifies indicators for responsible research and innovation

    Get PDF
    Professor Martin W. Bauer has been working as part of a small panel of experts who have recently published a new report on Indicators for promoting and monitoring responsible research and innovation. The report on Responsible Research and Innovation (RRI) is concerned with Science becoming more responsive to and better aligned with the values, needs and concerns of Society. Within the European Union, policy indicators are a preferred tool for monitoring, evaluating and self-criticising policies, so in 2014 an expert group was set up to design and select possible indicators for RRI as well as evaluating existing RRI-like indicators
