The theory of realizational morphology presented by Stump in his influential book Inflectional Morphology (2001) describes the derivation of inflected surface forms from underlying lexical forms by means of ordered blocks of realization rules. The theory presents a rich formalism for expressing generalizations about phenomena commonly found in the morphological systems of natural languages. Thi...

I review several bodies of empirical urban theory relevant to the archaeological analysis of ancient cities. Empirical theory is a type of “middlerange theory” (following Robert Merton): sets of concepts and methods that are less abstract, and have greater empirical content, than high-level social theory. The categories of theory reviewed here include environment-behavior theory, architectural ...

We derive a stochastic nonlinear continuum equation to describe the morphological evolution of amorphous surfaces eroded by ion bombardment. Starting from Sigmund s theory of sputter erosion, we calculate the coefficients appearing in the continuum equation in terms of the physical parameters characterizing the sputtering process. We analyze the morphological features predicted by the continuum...

The first morphological learner based upon the theory of Whole Word Morphology (Ford et al., 1997) is outlined, and preliminary evaluation results are presented. The program, Whole Word Morphologizer, takes a POS-tagged lexicon as input, induces morphological relationships without attempting to discover or identify morphemes, and is then able to generate new words beyond the learning sample. Th...

We study the variation of sputtering yields with surface morphologies under the assumption of a specially prescribed surface shape. Compared with a flat surface, we show that surface morphology can cause a decrease in the sputtering yield and an increase in the incident angle where sputtering yield is maximum. Based on Sigmund’s theory, an analytical formula for the morphology dependent sputter...
