The types and extent of regional phonetic and phonological variation in African American Vernacular English (AAVE), have, until quite recently, remained largely unknown and understudied, despite sociolinguists’ detailed knowledge of AAVE morphosyntax (Bailey & Thomas 1998). However, with the publication of the papers collected in Thomas & Yeager-Dror (in press), and a series of other recent pub...

A new Density-Functional (DF) formula is constructed for atoms. The kinetic energy of the electrons is divided into two parts: the kinetic self-energy and the orthogonalization energy where these concepts are borrowed from the pseudopotential theory. For the radial part of the orthogonalization energy which replaces the radial part of the Fermi-energy of the Thomas-Fermi model we derived the ex...
