New Experience: An Ethnographic Study Of Students Who Transfer From A Low-Performing Public School District To A Better-Performing Public School District In Missouri, Yolanda J. Campbell

Dissertations

School districts in Missouri are responsible for public K-12 education and must be accredited to educate children. As a result, there is an evoking interest, demanding attention in Missouri public schools' quality and the students who transfer from unaccredited, critically low-performing schools to accredited, significantly betterperforming schools. These students have a higher risk of failing academically or dropping out of school and transitioning successfully into adulthood. Therefore, through this study, students, parents/guardians, and teachers tell their stories to empower the public to work together to raise all students' achievement in school, close the poverty and opportunity gap in education, and …

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 …

White Voters And Minority Animus In The Era Of Trump, Zachary Schwartz

Dissertations

Overt and blatant racism of the type that was once used to justify Jim Crow laws and other forms of de facto segregation against Blacks has largely been forced into the margins of society. However, the reduction of overt racism that casts whites as biologically superior to Blacks can be easily confused with a reduction of racism in totality. The election and continued popularity of Donald Trump demonstrates that the conversation on race in the United States needs much more analysis. On multiple occasions during his campaign and presidency, Trump made inflammatory remarks on race and immigration, and yet suffered …
