1976 Go 1dsmi th ABSTRACT A modification of the theory of generative phonology is suggested in this thesis in the introduction of parallel tiers of segments (or "autosegments"). This is shown, in the first chapter, to resolve certain formal and substantive problems in the current theory. A detailed analysis of Igbo, a tone lang­ uage of Nigeria, is(More)
Despite their apparently divergent accounts of higher cognition, cognitive theories based on neural computation and those employing symbolic computation can in fact strengthen one another. To substantiate this controversial claim, this landmark work develops in depth a cognitive architecture based in neural computation but supporting formally explicit(More)
Acknowledgements I would like to begin by acknowledging the invaluable support of my advisor, Mark Johnson, whose level of knowledge and expertise I can only hope to achieve someday. Special thanks are also due to my other committee members: to Tom Griffiths, for arriving at Brown in the nick of time (among many other feats), and to Katherine Demuth and(More)
The topic of the syntax-phonology interface is broad, encompassing different submodules of grammar and interactions of these. This chapter addresses one fundamental aspect of the syntax-phonology interface in detail: the relation between syntactic constituency and the prosodic constituent domains for sentence-level phonological and phonetic phenomena. Two(More)
This paper describes in detail several explicit computational methods for approaching such questions in phonology as the vowel/consonant distinction, the nature of vowel harmony systems, and syllable structure , appealing solely to distributional information. Beginning with the vowel/consonant distinction, we consider a method for its discovery by the(More)
All reasoning is search and casting about, and requires pains and application. 1 Introduction The perspective that I will describe in this paper is the result of some work over the last ten years or so aimed at building an automatic morphological analyzer— that is, an explicit algorithm that takes natural language text as its input, and produces the(More)
Water vapor profiles from NASA's Lidar Atmospheric Sensing Experiment (LASE) system acquired during the ARM/FIRE Water Vapor Experiment (AFWEX) are used to characterize upper troposphere water vapor (UTWV) measured by ground-based Raman lidars, radiosondes, and in situ aircraft sensors. Initial comparisons showed the average Vaisala radiosonde measurements(More)
CONTEXT In 1997, Congress authorized the US Food and Drug Administration (FDA) to grant 6-month extensions of marketing rights through the Pediatric Exclusivity Program if industry sponsors complete FDA-requested pediatric trials. The program has been praised for creating incentives for studies in children and has been criticized as a "windfall" to the(More)
