A usage-based view takes grammar to be the cognitive organization of one’s experience with language. Aspects of that experience, for instance, the frequency of use of certain constructions or particular instances of constructions, have an impact on representation that are evidenced in speaker knowledge of conventionalized phrases, and in language variation and change. It is shown that particula...

Investigations of the motor organization of speech show that if we can identify individual segmental requirements, we can begin to predict the manner in which segments will influence each other in fluent speech. That is, we can model coarticulation as the outcome of temporal overlap (coproduction) among characteristic speech movements for successive segments (e.g., BellBerti & Harris, 1981; Fow...

Using the work by Bampi and Caviglia, we write the Weyl-Lanczos equations as an exterior differential system. Using Janet-Riquier theory, we compute the Cartan characters for all spacetimes with a diagonal metric and for the plane wave spacetime since all spacetimes have a plane wave limit. We write the Lanczos wave equation as an exterior differential system and, with assistance from Janet-Riq...
