A Discipline In Search Of A Voice: A Corpus Linguistic Study Of Evaluation Scholarly Literature, Aaron Wilson Kates

Dissertations

Linguists use the concept of discourse community (DC) to describe the speech of groups of people associated by some extrinsic purpose or interest (Swales, 1990). One defining feature of a DC is a shared lexicon. Scriven (1994), in his discussion of evaluation as a discipline, addresses the need for evaluation to have a “core subject” which would then allow, among other things, the development of “concepts and language to deal with core problems,” while noting that there exists a definite lack of clarity of language among evaluators (p. 147). Christie and Rose (2003) suggest that the lack of clarification around …

School Principals’ Awareness Of Their Emotional Intelligence And Connections To Leadership, Lourdes M. Pimentel Soto

Semi-Empirical Modeling Of Liquid Carbon's Containerless Solidification, Philip Chrostoski

Dissertations

Elemental carbon has important structural diversity, ranging from nanotubes through graphite to diamond. Previous studies of micron-size core/rim carbon spheres extracted from primitive meteorites suggest they formed around such stars via the solidification of condensed carbon-vapor droplets, followed by gas-to-solid carbon coating to form the graphite rims. Similar core/rim particles result from the slow cooling of carbon vapor in the lab. The long-range carbon bond-order potential was used to computationally study liquid-like carbon in (1.8 g/𝐜𝐦𝟑) periodic boundary (tiled-cube supercell) and containerless (isolated cluster) settings. Relaxations via conjugate-gradient and simulatedannealing nucleation and growth simulations using molecular dynamics were done to …
