Linearly constrained pseudo-Newton method

Must Newton-type methods for linearly constrained optimization be either of the modified Newton or quasi-Newton variety? The contention of this paper is that explicity recomputing part of the projected Hessian may be superior to both approaches. A computational comparison with MINOS is presented.     

A realist before ‘realism’: Quincy Wright and the study of international politics between two World Wars

Contrary to conventional belief, IR theorist Quincy Wright and his cohort before World War II were neither idealists, legalists, nor moralists. Deeply grounded in the realism and pragmatism that marked the University of Chicago's interwar climate, Wright applied an ethically neutral and empirical approach to understanding international relations. Unlike the stereotypical interwar theorist, Wright eschewed legalism. He recognized that a struggle for power drove international politics and would continue to do so for the forseeable future. Above all, Wright embraced the complexities of international politics, rejecting monocausal explanations for war or simplistic frameworks for understanding international relations.
