A Comparison of Appalachian and Non-Appalachian Kentucky DUI Offenders

Megan F. Dickson, Megan Kissel & J. Matthew Webster
Background: Driving under the influence has been an overlooked consequence of the opioid epidemic. Although recent reports have highlighted the increased prevalence of DUI in rural communities and the extensive mental health problems and criminal and drug use histories among rural Appalachian DUI offenders, it is unclear how Appalachian DUI populations compare to DUI offenders in other regions. Purpose: To help fill this void in the literature, the current study uses a statewide sample to...

Modern computer software systems are complicated. Developers can change the behavior of the software system through software configurations. The large number of configuration option and their interactions make the task of software tuning, testing, and debugging very challenging. Performance is one of the key aspects of non-functional qualities, where performance bugs can cause significant performance degradation and lead to poor user experience. However, performance bugs are difficult to expose, primarily because detecting them requires specific...

Essays on Price Discrimination and Demand Learning

Benjamin Wallace
This dissertation consists of three essays examining how and why firms set prices in markets. In particular, this dissertation shows how firms may utilize nonlinear pricing to price discriminate, how firms may experiment with the prices they set to learn about the demand function in the market they serve in later periods and the effects of these pricing strategies on consumer welfare. In Essay 1, I show how firms in the milk market use nonlinear...

Mechanisms of Type-I IFN Inhibition

Fatai Oladunni
Equine herpesvirus-1 (EHV-1) is one of the most important and prevalent viral pathogens of horses causing a major threat to the equine industry throughout most of the world. EHV-1 primarily causes respiratory disease but viral spread to distant organs enables the development of more severe sequelae; abortion and neurologic disease. In order to produce disease, EHV-1 has to overcome the innate barrier of the type-I interferon (IFN) system in host cells. However, the underlying mechanisms...

The Effect of States of Emergency on Gubernatorial Approval Ratings

Meghan Steinbeiss
To what extent do unexpected, apolitical events affect governors’ popularity? Individuals’ attitudes towards government are often random, and executives at both the state-level and national-level are held accountable for events that they have little control over. In this study, I seek to understand how these unplanned events affect support for elected officials. Specifically, I examine the effect of the declaration of a State of Emergency on gubernatorial approval. I use an ordinary least squares (OLS)...

Next generation defense and commercial applications for structural steels require new alloys that eliminate or reduce critical elements from their composition to lower cost and improve manufacturability, while maintaining or exceeding high strength and toughness requirements. A new alloy, denoted as AF9628, has recently been developed for this purpose and its manufacturing characteristics and the material response in component manufacturing must be fully understood. In the present study, hardened AF9628 alloy was turned with a...

Pathological Tau as a Cause, and Consequence, of Cellular Dysfunction

Shelby Meier
Tauopathies are a group of neurodegenerative diseases characterized by the abnormal deposition of the protein tau, a microtubule stabilizing protein. Under normal physiological conditions tau is a highly soluble protein that is not prone to aggregation. In disease states alterations to tau lead to enhanced fibril formation and aggregation, eventually forming neurofibrillary tangles (NFTs). The exact cause for NFT deposition is unknown, but increased post-translational modifications and mutations to the tau gene can increase tangle...

Evaluation of Roadway Lighting Practices

Brian K. Howell, William Nicholas Staats, Austin William Obenauf & Jerry G. Pigman
Adequate roadway lighting allows better driver visibility during nighttime conditions. Research studies show that lighted roadways on average experience 28 percent fewer vehicles crashes on all roadway types. Most state DOTs have historically used High-Pressure Sodium (HPS) lights for their roadside lighting programs due to their wide availability and relatively low purchase costs. However, the short lifespan of HPS results in frequent replacement, leading to high life cycle costs. Light-Emitting Diode (LED) lights consume less...

Relation Prediction Over Biomedical Knowledge Bases for Drug Repositioning

Mehmet Bakal
Identifying new potential treatment options for medical conditions that cause human disease burden is a central task of biomedical research. Since all candidate drugs cannot be tested with animal and clinical trials, in vitro approaches are first attempted to identify promising candidates. Likewise, identifying other essential relations (e.g., causation, prevention) between biomedical entities is also critical to understand biomedical processes. Hence, it is crucial to develop automated relation prediction systems that can yield plausible biomedical...

The Role of Place in Community Cooperative Food Markets in Lexington, Kentucky

Emily Rodes
Food justice movements focus on providing communities with local, sustainable, culturally appropriate, healthy food while empowering local economic systems that allow for autonomy of both producers and consumers (Caruso, C., 2014; Cadieux, K., 2015; Hayes, C. & Carbone, E., 2015). However, current food justice movements often price out and leave behind large portions of the population. Research has shown that engagement with local food systems contribute to feelings of place attachment and a sense of...


Robert Jacob Sivy
English progressive rock band Gentle Giant is catalogued under the progressive (or “prog”) rock genre for a variety reasons, including unique instrumentation, virtuosity, and interesting/unconventional musical attributes. The complexity of their music is often warranted by the sophisticated concepts behind their albums and the deep messages of their songs. The Power and the Glory (TPatG), Gentle Giant’s sixth studio album, is a concept album that emphasizes the rise and corruption of power. What makes their...


John Hast
Globally, male ungulate species are heavily managed for their sporting and trophy qualities. North American elk (Cervus canadensis) are typically managed using a male-biased harvest regime, placing increased chances of mortality on males in these hunted populations. To manage for trophy quality animals that typically represent older age classes, wildlife managers have implemented many age-biased harvest regulations, including spike-only tags and antler point restrictions. Many of these age-biased harvest regulations have fallen short of their...

Women Into Advanced Manufacturing

Carissa Schutzman
Women still rarely choose to seek employment in advanced manufacturing. Lack of familiarity with manufacturing jobs and education programs, lack of role models, and too few experiential opportunities contribute to women not choosing manufacturing jobs as well as other jobs traditionally held by men (Reha, Lufkin, & Harrison, 2009; St. Rose & Hill, 2013; Starobin & Laanan, 2008). Nontraditional jobs for women often provide higher wages and more opportunity for advancement than traditional jobs for...

William Nicholas Staats
Executive Summary Researchers compared the 2013 to 2017 fatal crash data from the KSP database to the crash data from the FARS database to check the consistency and accuracy of alcohol and drug involvement reporting for drivers in the KSP database. The indications of alcohol and drug involvement in the FARS database were used as the ground truth due to the inclusion of laboratory test results confirming the presence of alcohol and/or drugs in a...

Mechanisms of Trinucleotide Repeat Instability During DNA Synthesis

Kara Chan
Genomic instability, in the form of gene mutations, insertions/deletions, and gene amplifications, is one of the hallmarks in many types of cancers and other inheritable genetic disorders. Trinucleotide repeat (TNR) disorders, such as Huntington’s disease (HD) and Myotonic dystrophy (DM) can be inherited and repeats may be extended through subsequent generations. However, it is not clear how the CAG repeats expand through generations in HD. Two possible repeat expansion mechanisms include: 1) polymerase mediated repeat...
