This article explores the concept of «ancillary trauma», through which a woman character who has not been subjected to racial violence becomes traumatized actions male either psychically or emotionally damaged as result racist actions. While Morrison sympathizes with what characters endure, texts suggest that, in many cases, these lash out against women their lives an attempt emulate white masc...

Let Ax = b be a large, sparse, nonsymmetric system of linear equations. A new sparse approximate inverse preconditioning technique for such a class of systems is proposed. We show how the matrix A−1 0 −A−1, where A0 is a nonsingular matrix whose inverse is known or easy to compute, can be factorized in the form UΩV T using the Sherman–Morrison formula. When this factorization process is done in...

The analytic element method, like the boundary integral equation method, gives rise to a system of equations with a fully populated coefficient matrix. For simple problems, these systems of equations are linear, and a direct solution method, such as Gauss elimination, offers the most efficient solution strategy. However, more realistic models of regional ground water flow involve nonlinear equa...

It should come as no surprise to readers of QEX that the scientific Search for Extra-Terrestrial Intelligence (SETI, sometimes called the search for the ultimate DX) was initiated by, and is still largely conducted by, radio amateurs. The world’s hams instinctively understand the nature of electromagnetic communications, as well as the nature of the “free space” (or “aether”) that fills the voi...

While sorting through mountains of articles and books about the works of Toni Morrison, I realized there existed a glaring omission in the literature: there was yet to be published a single volume that solely addressed the characterization of mothers in Morrison's narrative. Given that I compare portraits of maternity in novels by women authors of the Americas in my doctoral work, I was overcom...

The Supreme Court's recent decisions in United States v. Lopez and United States v. Morrison articulate a vision of federalism under which Congress's regulatory authority under the Commerce Clause is severely limited in favor of returning traditional areas of state concern, particularly criminal law enforcement, to local or state control. The Court's decisions in these cases coincide with ball...
