Biotic and abiotic factors interact with dominant plants —the locally most frequent or with the largest coverage— and non-dominant plants differently, partially because dominant plants modify the environment where non-dominant plants grow. For instance, if dominant plants compete strongly, they will deplete most resources, forcing non-dominant plants into a narrower niche space. Conversely, if dominant plants are constrained by the environment, they might not exhaust available resources but instead may ameliorate environmental stressors that usually...

Best Practices for Performance Measurement in Transportation Operations and Maintenance

Bryan Gibson, Rachel Catchings, Chris Van Dyke, Steve Waddle & Doug Kreis
Public agencies benefit from measuring their performance as it helps to focus employee and organizational activities. State departments of transportation have become more performance-oriented over the past two decades and routinely collect data on highway safety, infrastructure condition, system operations, project delivery, winter maintenance, transit, bicycle and pedestrian facilities, and customer service. While the Kentucky Transportation Cabinet (KYTC) use performance measures in a variety of areas, the agency wants to adopt new metrics related to...

THE EFFECTS OF USING CONSTANT TIME DELAY TO TEACH DIGRAPHS TO ELEMENTARY STUDENTS WITH MILD DISABILITIES

Sara Schuer
Constant time delay (CTD) is a near-errorless response prompting procedure that involves a presentation of a stimulus, a delay interval, and a controlling prompt. The purpose of this study was to determine the effectiveness of teaching vowel/consonant digraph sounds to children with mild disabilities using constant time delay. A multiple probe (conditions) across behaviors design, replicated with three students, was used. The results indicated that CTD is effective in teaching vowel/consonant digraphs to elementary students...

Research on Power System State Estimation Problems – Series-Compensated Transmission Line Parameter and Load Model Parameter Estimation

Yiqi Zhang
Transmission line and load model parameters are essential inputs to power system modeling and simulation, control, protection, operation, optimization, and planning. These parameters usually vary over time or under different operating conditions. Thus, reliable estimation methods are desired to ensure the accuracy of those parameters. This research focuses on estimation for transmission line parameters and the ZIP load model. The proposed estimation methods can use both online measurements and historical data of a specified duration....

THE EFFICACY OF ACCELERATING UNDERPREPARED COMMUNITY COLLEGE STUDENTS USING A COREQUISITE LIBERAL ARTS MATHEMATICS COURSE

Drew Wilkerson
Every year, millions of first-time students enroll in community colleges underprepared for college-level work in mathematics. Typically, these students are referred to a sequence of developmental courses designed to remediate their skills and prepare them for college-level work. Recently, educators and policy makers have questioned the efficacy of these courses, especially since most students assigned to remedial courses never complete the sequence and enroll in college-level courses. Calls to reform developmental mathematics have included changes...

Fluid Dynamics

James Evans
Water has remained a subject of all kinds of musical works since at least the middle ages. These musical works lack the concrete representational capacity of paintings, photographs, and films, relying instead on more abstract metaphorical constructs to convey water imagery. Current scholarship on water music typically centers on Romantic and Impressionist works and does not examine the process of signification by which musical signs portray water. The principal goal of this study is to...

2020 Kentucky Transportation Cabinet Maintenance Customer Survey

Bryan Gibson, Katherine Connair, Chris Van Dyke, Clark Graves & Doug Kreis
The Kentucky Transportation Cabinet (KYTC) periodically surveys drivers to understand their perceptions of the agency’s maintenance activities. In 2020, Quadratics in conjunction with the Kentucky Transportation Center surveyed 2,400 licensed drivers throughout the state to gauge their perceptions of highway maintenance, identify areas of strength and weakness, and discern how drivers obtain information on traffic and weather conditions. Survey participants answered questions about five areas of highway maintenance — roadside features, pavement surfaces, shoulders, drainage,...

THE ROLES OF THE ACTIN NETWORK AND CO-OPTED HOST FACTORS IN TBSV REPLICATION

Melissa Molho
Positive-stranded (+) RNA viruses are the largest family of viruses that infect plants, causing important economic losses in different crops. Tomato bushy stunt virus (TBSV), a small positive-stranded RNA virus, has emerged as a model virus to study virus-host interactions. TBSV encodes for only five proteins, therefore, to infect the host cell TBSV co-opts selected host components and subverts specific molecular pathways. Firstly, I performed a proteomic screening using Arabidopsis proteins. I found that TBSV...

Glenna Erin Joyce
Arabinoxylan (AX) is a major structural polysaccharide found in the cell walls of monocots such as cereal grains and pasture grasses. The variety of AX structural components and substitution patterns contribute to AX structural diversity between different monocot species as well as plant tissues. The rumen is the first digestion site of masticated food material in cattle and provides 70% of energy to host through fermentation of forage. There are many species of pasture grasses...

“IT’S THE ONLY THING WE HAVE”

Richard Carter
Women who secretly warn one another via informal communications about men in their environment who may engage in some kind of misconduct are participating in a whisper network. This dissertation employs the narrative paradigm to understand how these networks function in the context of professional actors. Interviews conducted with actors who have worked in a variety of communities were analyzed in order to better understand how whisper networks function as warning systems that must be...

DEVELOPMENT AND CLINICAL VALIDATION OF KNOWLEDGE-BASED PLANNING MODELS FOR STEREOTACTIC BODY RADIOTHERAPY OF EARLY-STAGE NON-SMALL-CELL LUNG CANCER PATIENTS

Justin Visak
Lung stereotactic body radiotherapy (SBRT) is a viable alternative to surgical intervention for the treatment of early-stage non-small-cell lung cancer (NSCLC) patients. This therapy achieves strong local control rates by delivering ultra-high, conformal radioablative doses in typically one to five fractions. Historically, lung SBRT plans are manually generated using 3D conformal radiation therapy, dynamic conformal arcs (DCA), intensity-modulated radiation therapy, and more recently via volumetric modulated arc therapy (VMAT) on a C-arm linear accelerator (linac)....

MULTIPLE PROTEINOPATHIES AND THEIR ROLE IN COGNITIVE IMPAIRMENT AND NEURODEGENERATIVE DISEASES

Shama Karanth
Most age-related neurodegenerative disorders are associated with the aggregation of misfolded and aberrant proteins. Alzheimer’s disease (AD) is one of the most common neurodegenerative disorders and is highly prevalent in older adults. Neuropathologically, AD is characterized by the accumulation of amyloid-β (Aβ) plaques and neurofibrillary tangles (NFTs). Other misfolded proteins, including α-synuclein and transactive response DNA-binding protein 43 (TDP-43), are also commonly observed in aged brains. Aberrant α-synuclein has been associated with Parkinson's disease, Dementia...

Luke Cummings
This thesis is composed of two essays regarding the dairy industry of North America. The first essay aims to evaluate the adoption of an MCP pricing system in the Appalachian FMMO. Producers in Georgia, Kentucky, Tennessee, and North Carolina have formally voiced concern about adopting MCP due to concerns over reduced milk value. Using cow-level production data from Kentucky, the effect on farm level prices can be estimated. It is determined Jersey cow herd’s milk...

Novel Methods for Characterizing Conditional Quantiles in Zero-Inflated Count Regression Models

Xuan Shi
Despite its popularity in diverse disciplines, quantile regression methods are primarily designed for the continuous response setting and cannot be directly applied to the discrete (or count) response setting. There can also be challenges when modeling count responses, such as the presence of excess zero counts, formally known as zero-inflation. To address the aforementioned challenges, we propose a comprehensive model-aware strategy that synthesizes quantile regression methods with estimation of zero-inflated count regression models. Various competing...

Beyond the Notation

Brent Johnson
Music is a subjective art form that is enhanced by emotional connection and understanding of the relationship of line and phrasing to both the performer and the audience. Performers and conductors are charged with making artistic decisions about the expressive qualities of a phrase within moments of seeing the notation for the first time. In the development of wind ensembles, there is often a disconnect between the technique and accuracy of a musician’s performance and...

He is known for fusing his African American musical tradition of Jazz and blues with the classical European musical tradition. This study explores one of Still’s most famous song cycles, “Songs of Separation,” in the arrangement for string quartet, voice, and piano. This document considers...

Race Youth in Twentieth-Century American Literature and Culture

Claire Lenviel
Race Youth in Twentieth-Century American Literature and Culture argues for the centrality of black youth, both real and literary, to the trajectories of African American literature and its repudiation of white supremacy. Drawing on research into the rise of the adolescent and teenager as distinct social categories, I argue that age-based subjectivity should inform how we read race-based subjectivity. My first chapter explores how early twentieth-century black periodicals push back against white supremacist theories of...
