Corrupt and Unequal, Both

Rick Hasen has presented the issue of money in politics as if we have to make a choice: it is either a problem of equality or it is a problem of corruption. Hasen’s long and influential career in this field has been a long and patient struggle to convince those on the corruption side of the fight (we liberals, at least, and, in an important sense, we egalitarians too) to resist the temptation to try to pass—by rendering equality arguments as corruption arguments, and to just come out of the closet. Hasen had famously declared that the corruption argument supporting Austin v. Michigan Chamber of Commerce was a fake and that the only basis for justifying the ban on corporate spending in Austin was equality, not corruption. And the U.S. Supreme Court famously (in our circles at least) agreed, in the process of striking down the ban on corporate spending in Austin and everywhere else. Thus, Hasen argues, it is a fool’s errand to fake the corruption argument. We need instead, Hasen has constantly counseled, a bit of egalitarian pride. Be true to ourselves, Hasen tells us, and give up the pretense of corruption talk

Energy conservation and numerical stability for the reduced MHD models of the non-linear JOREK code

In this paper we present a rigorous derivation of the reduced MHD models with and without parallel velocity that are implemented in the non-linear MHD code JOREK. The model we obtain contains some terms that have been neglected in the implementation but might be relevant in the non-linear phase. These are necessary to guarantee exact conservation with respect to the full MHD energy. For the second part of this work, we have replaced the linearized time stepping of JOREK by a non-linear solver based on the Inexact Newton method including adaptive time stepping. We demonstrate that this approach is more robust especially with respect to numerical errors in the saturation phase of an instability and allows to use larger time steps in the non-linear phase
