Orbital Stability Results for Soliton Solutions to Nonlinear Schrödinger Equations with External Potentials

Joseph B. Lindgren
For certain nonlinear Schroedinger equations there exist solutions which are called solitary waves. Addition of a potential $V$ changes the dynamics, but for small enough $||V||_{L^\infty}$ we can still obtain stability (and approximately Newtonian motion of the solitary wave's center of mass) for soliton-like solutions up to a finite time that depends on the size and scale of the potential $V$. Our method is an adaptation of the well-known Lyapunov method. For the sake of...

EXPLORING THE QUALITY OF LIFE IMPACT OF THE BLUEGRASS DOUBLE DOLLARS PROGRAM

Rebecca L. Warta
Food Security is a situation that exists when all people, at all times, have physical, social, and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life (FAO, 1996). 17% of Kentuckians are food insecure (Kentucky Department of Agriculture, 2016). This study explored the quality of life (QoL) impact of the Bluegrass Double Dollars (BGDD) program on Supplemental Nutrition Assistance Program (SNAP) participants...

EVALUATING THE QUALITY OF ONLINE COURSES WITHIN THE KENTUCKY COMMUNITY AND TECHNICAL COLLEGE SYSTEM (KCTCS)

Kevin R. Dunn
The purpose of this exploratory, multi-phased iterative study was to explore the extent to which Kentucky Community and Technical College (KCTCS) faculty utilize quality standards during the design and continuous improvement of their online courses. The study also explored how leadership supports quality online instruction. More specifically, this study sought (a) to determine to what degree KCTCS quality assurance rubrics aligned with national quality standards, (b) to what degree did faculty use quality standards to...

THE XENOBIOTIC TRANSCRIPTION FACTOR CAP N COLLAR C REGULATES EXPRESSION OF MULTIPLE INSECTICIDE RESISTANT GENES

Megha Kalsi
Insecticide resistance is a global problem. Insecticide resistance management is very important, considering the time, effort, and cost of discovering and developing a new insecticide. There are diverse resistance mechanisms, but enhanced detoxification through overexpression of cytochrome P450s and target site insensitivity through mutation in insecticide binding site are the two most common mechanisms. The xenobiotic detoxification is divided into three successive phases (I, II and III), which ensures the metabolism and excretion of the...

Ethnic Xenophobia as Symbolic Politics

Annamarie M. Rannou
Xenophobia is examined almost exclusively as a prejudice of advanced western nations. I argue that the field of study of xenophobia must be re-conceptualized in order for comparative, cross-regional inquiry to take place. With a new concept of ethnic xenophobia, this dissertation examines the determinants and causal mechanisms of ethnic xenophobic activity across developed and developing countries. I integrate studies of xenophobia and theories of ethnic threat to explain that political elites rely on structural...
