African American Men’S Health: Regulating Race-Related Stress Through Cognitive Flexibility, Brian P. Littleton

Dissertations

African American men have one the highest preventable mortality and morbidity rates in the United States (Rich, 2000; U.S. Department of Health and Human Services, 2015). Moreover, there is substantial health disparity between African American men and White men in the United States (Smedley, Stith, & Nelson, 2003). It has been stated that pervasive racism and discrimination are the most significant contributors for the disparity. Studies have shown race-related stress, which is derived from experiencing racism, discrimination or having internalized feelings as the result of an individual’s racial status, has been associated with blood pressure, emotional distress, and physical health …

Transitioning Children With Autism From One-On-One Discrete-Trial Settings To Special Education Classrooms, Jennifer L. Freeman

Dissertations

The goal of an early intensive behavioral intervention (EIBI) program is to teach each child the skills necessary to make meaningful progress in less-restrictive environments (Fox, Dunlap & Crushing, 2002). However, few studies have detailed the steps necessary for a “successful” transition into these educational settings. We transitioned two children, who received 20 hours a week of one-on-one discrete-trial therapy and attended a half-day special education pre-school classroom, to a full-time educational setting. With the goal of aiding each during his/her transition, this study used the Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP) (Sundberg, 2008), particularly the barriers and …

Three Essays Assessing Global Value Chain Fragmentation On International Trade Using The World Input-Output Database, Johanna Retana Attoh

Dissertations

The growing fragmentation of supply chains across countries have changed the way nations engage in international trade. Conventionally, studies have used data on exports to measure trade flows; however, the use of this type of data imposes many assumptions that might misrepresent the real world. For instance, the assumption that the supply chain of a product is confined in only the domestic country does not take into consideration the increasing number of foreign inputs needed to produce a final good. In this dissertation, I use the World Input-Output Database (WIOD), since this dataset allows one to track and decompose the …

Optimization Methodology For Cvt Ratio Scheduling With Consideration Of Both Engine And Cvt Efficiency, Steven Beuerle

Masters Theses

A transmission ratio schedule is developed to optimize the fuel consumption for an automotive continuously variable transmission (CVT) connected to an internal combustion engine (ICE). Although the optimal operating line (OOL) generated from an engine brake specific fuel consumption (BSFC) map can be used to generate a CVT ratio schedule that yields maximum engine efficiency, it was found that OOL-based CVT ratio scheduling does not necessarily offer the best fuel economy because optimal CVT efficiency does not always correspond to OOL tracking. To develop a CVT ratio schedule that can offer the best fuel economy, a novel ratio-scheduling methodology is …

“A Course No One Wants To Teach”: A Brief History Of The Undergraduate Writing Methods Course, Christine E. Tulley

Teaching/Writing: The Journal of Writing Teacher Education

In this essay, I untangle two historically embedded challenges within the undergraduate writing methods course that continually reestablish divisions between theory and pedagogy (and often English and education departments by association) for preservice teachers. The two issues are:

1. The lack of status of the undergraduate writing methods course within English departments, entrenched by the historically marginalized reputations of both rhetoric and composition and English education programs; and

2. Internal disputes within the field of rhetoric and composition over a theoretical versus pedagogical emphasis for the undergraduate writing methods course, and external debates between the fields of rhetoric and composition …

Reimagining Instructional Practices: Exploring The Identity Work Of Teachers Of Writing, Melody Zoch, Joy Myers, Claire Lambert, Amy Vetter, Colleen Fairbanks

Teaching/Writing: The Journal of Writing Teacher Education

This article provides a cross-case analysis of three teachers who participated in a two-week professional development (PD) on the teaching of writing that addressed their own identities as writers. This is an area that is commonly overlooked and how teachers view themselves as writers may play an important role in how they help their students to think of themselves as writers, may shape the conversations they have about writing, and may influence the kinds of writing opportunities they provide. Drawing on an identity perspective, the findings illustrate how the opportunity to construct and enact writing identities shaped how the teachers …
