AbstractThe fact that Veblen was a keen critic of the neo-classical concept of “economic man” is well known. However, the following issues have not been discussed in enough depth: how he rebuilt the traditional theory of human nature through his new methodology of economics, how much his methodological revision broadened the scope of economics, and what kind of phenomena Veblen’s economic theory elucidates. This article examines these issues and aims to show the logical connection between Veblen’s controversial proposal on the methodology of economics and his analysis of economic phenomena. Specifically, it reconsiders Veblen’s analysis of economic action using a unique concept of instincts, his logic of explaining the relation between society and human nature, his way of drawing history from the relativistic worldview, and his characteristic method of grasping the cause and effect of economic phenomena. Finally, it highlights the importance of modifying the concept of “economic man” by focusing on the qualitative aspect. Particular reference is made to the economic concepts of utility, efficiency, and intangibility.

The Magnetic Field

This paper considers the numerical optimization of a double ramp scramjet inlet using magnetohydrodynamic (MHD) effects together with inlet ramp angle changes. The parameter being optimized is the mass capture at the throat of the inlet, such that spillage effects for less than design Mach numbers are reduced. The control parameters for the optimization include the MHD effects in conjunction with ramp angle changes. To enhance the MHD effects different ionization scenarios depending upon the alignment of the magnetic field are considered. The flow solution is based on the Advection Upstream Splitting Method (AUSM) that accounts for the MHD source terms as well. A numerical Broyden-Flecher-Goldfarb-Shanno- (BFGS-) based procedure is utilized to optimize the inlet mass capture. Numerical validation results compared to published results in the literature as well as the outcome of the optimization procedure are summarized to illustrate the efficacy of the approach.
