Conclusions : Causality Between Plurality and Unity
No full textThe previous chapters convey the image of causal analysis in public policy and beyond as a fragmented field where research communities seldom learn from each other's findings. This chapter resumes the ontological, epistemological, and methodological evidence that causal analysis is characterized by a plurality of objects and ``incommensurable'' interpretations. It also argues that the same evidence pinpoints how this plurality is complementary at every level, and causal structures raise as the elements that link ontology and methodology and can organize heterogeneous findings to improve learning across accounts
Reduced basis approximation of parametrized optimal flow control problems for the Stokes equations
No full textThis paper extends the reduced basis method for the solution of parametrized optimal control problems presented in Negri et al. (2013) to the case of noncoercive (elliptic) equations, such as the Stokes equations. We discuss both the theoretical properties with particular emphasis on the stability of the resulting double nested saddle-point problems and on aggregated error estimates - and the computational aspects of the method. Then, we apply it to solve a benchmark vorticity minimization problem for a parametrized bluff body immersed in a two or a three-dimensional flow through boundary control, demonstrating the effectivity of the methodology.

Foundation and empire : a critique of Hardt and Negri
No full textIn this article, Thompson complements recent critiques of Hardt and Negri's Empire (see Finn Bowring in Capital and Class, no. 83) using the tools of labour process theory to critique the political economy of Empire, and to note its unfortunate similarities to conventional theories of the knowledge economy
Introduction: The Elephant of Causation and the Blind Sages
No full textWhat does a policy outcome hinge on? The response is vital to policy-making and calls for the best of our knowledge from a variety of disciplines—from economics to sociology and from political science to public administration and management. The response entails a stance about causation, however, and almost
every discipline has its own. Researchers are like the blind sages who had never come across the elephant of causation before and who develop their idea of the elephant by “touching” a different part of it. Which part of the elephant will you
happen to touch? Will you be able to listen to and understand what the other sages will tell you
