Coalition oversight and blame avoidance in Greece

This article examines the behavior of Greek political parties before, as well as during, the recent austerity period. Drawing on coalition oversight and blame avoidance literature, it argues that the unpopularity of austerity governments leads to extreme levels of dissent within the coalition. I operationalize this ‘intra-coalition opposition’ behavior using parliamentary questions, a legislative institution that has not been studied in the context of coalition politics. The analysis demonstrates that junior members in unpopular austerity governments increase their use of parliamentary questions to a degree that matches or even exceeds the formal opposition. However, intra-coalition dissent is conditional on the type of unpopular government policies, and on the ideology of coalition members. Specifically, using a new method of text analysis, I show that while the socialist Panhellenic Socialist Movement uses its parliamentary questions to avoid or minimize the blame associated with austerity policies, the conservative New Democracy does not, because left-leaning parties are electorally vulnerable to austerity measures. The results have implications for studying dissent in coalition politics in general, and the politics of austerity in particular

A mathematical formulation of the boundary integral equations for a compressible stokes flow

A general boundary integral formulation for compressible Stokes flows is theoretically described within the framework of hydrodynamic potentials. The integral equation is implemented numerically to the study of drop expansion in compressible viscous flows. Marker point positions on the drop interface are involved by using the boundary integral method for calculation of fluid velocity. Surface discretization is adaptive to the instantaneous drops shapes. The interplay between viscous and surface tension and its influence on the evolving emulsion microstructure during its expansion is fundamental to the science and technology of foam processing. In this article the method is applied for 3D simulations of emulsion densification that involves an uniform expansion of a viscous fluid containing spherical drops on a body centered cubic lattice (BCC)

Direct numerical simulations of emulsion flows

In this paper, three-dimensional boundary integral computer simulations of emulsions in shear flows are described. Results for ordered BCC emulsions with dispersed-phase volume fractions below the critical concentration are presented. Complex rheological features including: shear-thinning viscosities, normal stress differences, and a nonlinear frequency response are also explored. For deformable drops, pair wise collision produces net cross-flow displacements that govern self-diffusion of drops. We compute trajectories of two interacting drops in shearing and present interesting numerical simulations of three dimensional gravity-induced motion of two drops. The results also demonstrate the feasibility of simulating high-volume-fraction emulsions and foam
