During the late 1990s, as the debate over affirmative action escalated, Texas moved into the national limelight. After the U.S. Court of Appeals for the Fifth Circuit found the use of race or ethnicity in college admissions unconstitutional in Hopwood v. Texas, the state embarked on a bold experiment. In 1997, the Texas legislature passed H.B. 588, commonly termed the Top Ten Percent Law, which...

We obtain a characterization of the Lie algebras admitting abelian complex structures in terms of certain affine Lie algebras aff(A), where A is a commutative algebra.

2) MHM(pt) is the category of graded polarizable rational mixed Hodge structures, such that rat is the forgetful functor 3) M ∈MHM(X) admits a weight filtration W • satisfying -morphisms preserve W • strictly -Gr k M is semisimple -W • on pt is the usual weight filtration 4) MHM(X) has a duality functor D For a morphism s : X → Y DMHM(X) has functors f∗, f!, f∗, f , that are sent by rat and Dmo...

Interpersonal Comparisons of Utility: An Algebraic Characterization of Projective Preorders and Some Welfare Consequences It is shown that any completely preordered topological real algebra admits a continuous utility representation which is an algebra-homomorphism (i.e., it is linear and multiplicative). As an application of this result, we provide an algebraic characterization of the projecti...

OBJECTIVES To determine outcomes and markers of serious illness for febrile patients presenting to an adult emergency department. METHODS A prospective cohort study of patients presenting to the emergency department with a temperature >or=38 degrees C. Medical staff obtained demographic data and risk factor profiles while assessing each febrile patient. All were followed up to determine death...

Obstructions of rational commensurability of reducible surface automorphisms are given. There are 3-manifolds admitting different surface bundles structures with monodromies not rational commensurable.

When inquiries to the Cardiff Centre of the National Poisons Information Service were compared with hospital admissions in the eight health authorities in Wales the findings suggested fewer admissions in the area within which the centre is situated and showed a more extensive use in that area than elsewhere. High inquiry rates were associated with high hospital admission rates when the eight ar...

We prove that for each closed smooth spin 4-manifold M there exists a closed smooth 4-manifold N such that M#N admits a conformally flat Riemannian metric.
