Is Athlete Activism a Predictor of Resilience?

Travis Scheadler
Several athletes have taken personal responsibility to engage in activism, often with hopes of bringing social and political change. While scholars have identified several barriers preventing athletes from engaging in activism (e.g., public criticism, status and job loss, withdrawal of funding, anticipated distress; Cunningham & Regan, 2012), other scholars have identified personal benefits from engaging in activism (e.g., improved confidence, self-concept, belief in change, agency, life meaning; Klar & Kasser, 2009; Rabkin et al., 2019)....

EXPERIENCES OF ADOLESCENTS IN THE GENERAL EDUCATION SETTING INTERACTING WITH PEERS WITH INTELLECTUAL DISABILITY

Katie Goldey
Social interaction is critical to health, quality of life, and linguistic and cognitive development. However, young people with intellectual disabilities are unlikely to have equitable opportunities for social interaction. This may be particularly true of adolescents. This study used qualitative phenomenological methods to examine the lived experiences of students in the general education setting interacting with their peers with intellectual disability. Twenty participants engaged in one on one interviews with the author. Interviews were recorded,...

disClosure, Volume 28: Affect

Robby Hardesty & Alina Hechler
The 2018-19 Editorial Collective is pleased to present the 28th volume of disClosure: A Journal of Social Theory. Our inspiration for this odd bundle of pages is rooted in the aesthetic of the self-printed zine. While we regret that we couldn't sneak into Miller Hall in the middle of the night to guerrilla-copy the entire issue on a late-80s black-and-white Xerox, we are proud to say that each page of this volume was assembled entirely...

MANAGEMENT OF SUGARCANE APHID (MELANAPHIS SACCHARI) USING BIOLOGICAL AND CULTURAL TACTICS IN KENTUCKY

Nathan Mercer
In 2013, a new aphid pest of sorghum, the sugarcane aphid Melanaphis sacchari Zehntner (Hemiptera: Aphididae), was found in the southern US, and caused significant yield loss in sorghum. Since then, M. sacchari has spread to most of the sorghum growing regions. Unmanaged populations can cause complete crop loss in grain, forage and sweet sorghum. M. sacchari cannot survive winters without a live plant tissue and must recolonize much of its pest range annually. Sweet...

THE IMPACT OF BONE MARROW TRANSPLANTION ON PATIENTS WITH PSYCHIATRIC DIAGNOSES

Brittany Galop
Objectives: We investigated whether there is a measurable difference in medication utilization for psychiatric conditions before and after bone marrow transplantation (BMT). Previous studies have identified a potential association between psychiatric conditions and immune function. We hypothesized that medication utilization for psychiatric diagnoses would be impacted by BMT. Methods: This study was a retrospective, quasi-experimental cohort design. De-identified data was compiled from the Truven database for patients ranging from January 2009 through December 2016. Two...

Nanomaterials for Double-Stranded RNA Delivery

Stuart Lichtenberg
RNA interference has enormous potential as a potent, specific, and environmentally friendly alternative to small molecule pesticides for crop protection. The use of exogenous double-stranded RNA offers flexibility in targeting and use in crops in which transgenic manipulation is not an option. The combination of RNAi with nanotechnology offers further advantages that are not available with dsRNA alone. In this work, I have evaluated several different combinations of nanomaterials and polymers for use in RNAi-based...

Cover Crops and Cover Crop Mixes

LANDON GIBBS
The potential nutrient cycling benefits from legumes (e.g. N2-fixation) and the high biomass potential of cereal rye are well known. Further studies are warranted to evaluate bi-culture mixtures and their effects on soil nutrient stratification and microbial enzyme activity because these two properties may be differently expressed (enhanced) by legume/grass mixes. The objectives of this study were: (1) show different cover crops and cover crop mixes containing grasses and legumes differentially stratify carbon and N;...

INFLUENCE OF WATER INJECTION RATE ON THE VORTECONE, AN IMPINGEMENT SCREEN, AND A CONVENTIONAL FILTER SCREEN CLEANING EFFICIENCY

Oscar Velasquez
Industrial produced respirable particles are known to affect the respirable tract of workers causing serious illness or even death. These particles can be found in any mining operation’s environment, new regulations by the Mine Safety and Health Administration (MSHA) in 2014 reduced the allowable limit of dust exposure for underground workers. Dust control practices have been improving over the years to lower the number of incidents caused by these particles. In underground mining, water sprays...

LOST & FOUND AN ELECTRO-ACOUSTIC MUSICAL COMPOSITION REFERENCING A DAY IN AN AFRICAN VILLAGE

George Essilfie
Electro-acoustic music composition makes it possible for composers to manipulate sounds with the computer with either alone or both live and prerecorded sounds. From the end of the 19th century when the first electronic devices for performing music were developed up till today, transformations in music technology keep surfacing and the possibilities with working with sounds have become endless. Electro-acoustic music has the ability to conjure mental images using vast sound manipulation techniques using the...

Instructor-Student Rapport as a Psychological Need for Students

Nicholas Tatum
There is a need to explore ways to better motivate students in instruction, as student motivation is an issue confronting teachers at all levels of education. Instructor-student rapport (ISR), a multidimensional concept comprised of students’ enjoyable interaction and personal connection with instructors, has potential to offer educators a tool for increasing these important student outcomes. Further, self-determination theory (SDT) may have utility for illustrating the psychological mechanisms through which instructors influence students by building rapport....

Xiaojia Ren
The rate of cancer patients is increasing as the development of science and technology. Twenty million cancer survivors are estimated living in the United States by 2025. However, many cancer survivors show cognitive dysfunction, negatively affecting the quality of life. These cognitive impairments are recognized as chemotherapy-induced cognitive impairment (CICI), also called "chemo brain" by cancer survivors, including the diminished ability of memory and learning, hard to concentrate and focus, as well as diminution of...

A COMPREHENSIVE ASSESSMENT OF CRISIS IN INDIVIDUALS WITH INTELLECTUAL DISABILITIES AND ITS IMPLICATIONS FOR PHYSICAL THERAPY

Kathleen Sutton
Advancements in medicine, policy, and societal attitudes have improved life expectancy, socialization, and participation for individuals with intellectual and developmental disabilities (IDD). However, inconsistent or a lack of services may drive healthcare utilization toward expensive emergency care services. This can negatively impact health outcomes and disrupt physical therapy treatment plans, limiting their effectiveness and further placing individuals with IDD at risk for crisis episodes. Because of its subjective nature, quantifying crisis is challenging using current...

Optimum Design of Axial Flux PM Machines based on Electromagnetic 3D FEA

Narges Taran
Axial flux permanent magnet (AFPM) machines have recently attracted significant attention due to several reasons, such as their specific form factor, potentially higher torque density and lower losses, feasibility of increasing the number of poles, and facilitating innovative machine structures for emerging applications. One such machine design, which has promising, high efficiency particularly at higher speeds, is of the coreless AFPM type and has been studied in the dissertation together with more conventional AFPM topologies...

SINGLE-DEGREE-OF-FREEDOM EXPERIMENTS DEMONSTRATING ELECTROMAGNETIC FORMATION FLYING FOR SMALL SATELLITE SWARMS USING PIECEWISE-SINUSOIDAL CONTROLS

Ajin Sunny
This thesis presents a decentralized electromagnetic formation flying (EMFF) control method using frequency-multiplexed sinusoidal control signals. We demonstrate the EMFF control approach in open-loop and closed-loop control experiments using a single-degree-of-freedom testbed with an electromagnetic actuation system (EAS). The EAS sense the relative position and velocity between satellites and implement a frequency-multiplexed sinusoidal control signal. We use a laser-rangefinder device to capture the relative position and an ARM-based microcontroller to implement the closed-loop control algorithm....

THE ECONOMICS OF MILK QUALITY MANAGEMENT PRACTICES AND MILK PRICING IN SIMULATED UNITED STATES DAIRY HERDS

Derek Thomas Nolan
Mastitis is considered one of the most common and costly diseases in the dairy industry. Intramammary infection status at a herd level is measured using somatic cell count (SCC). Understanding the total cost of an elevated somatic cell count can help influence dairy farmers to lower SCC and select management practices to produce higher quality milk. The first objective of our research was to determine if the cost of an elevated somatic cell count to...

Waking Sleep

Delmar R., Jr. Reffett
With the dawning of the twentieth century, writers and critics found themselves facing a social world undergoing massive change, the forces of capitalist modernity leaving the individual increasingly disaffected and disconnected from her surroundings. This social world, rent as it was by alienation, offered a hostile environment for the sort of coherence that had traditionally been prized by Western aesthetics since the Enlightenment. How could a literary work attain a degree of coherence while reflecting...

The Ecology and Behavior of Spring Migrating Indiana Bats (Myotis sodalis)

Piper Lee Roby
Migration of animals has been studied for decades and has included everything from large terrestrial and pelagic mammals traveling thousands of kilometers to many types of birds flying through several countries to insects going through multiple life cycles in a single migration. The migration of bats has been studied in broad terms to gather coarse information such as distance traveled, connecting summer and winter habitat, and a general understanding of timing. However, only recently have...

BEING AND STRUCTURE IN PLATO’S SOPHIST

Colin C. Smith
Being and Structure in Plato’s Sophist is a study of the metaphysical notion of being as it is at play in Plato’s dialogue the Sophist, and the senses in which Plato’s conception of being entails further accounts of ontological structure and goodness. While modern metaphysics primarily concerns existence, ancient metaphysics primarily concerns what grounds what, and in this dissertation I consider the nature and value of Plato’s understanding of being as a notion of ground...

THE ROLES OF POLAR CELL EXTENSIONS IN DROSOPHILA MICROPYLE FORMATION

Bradford Hull
The Drosophila micropyle is a conserved formation utilized to allow sperm passage past the robust eggshell structure for fertilization. Micropyle formation follows a unique acellular tubulogenesis method where it is secreted and shaped by specialized follicle cells including the border cells and polar cells. In late oogenesis, the polar cells form extensions that are necessary to create the micropyle pore through which sperm enters. Previous work established that polar cell extension presence is required for...

Nonparametric Analysis of Clustered and Multivariate Data

Yue Cui
In this dissertation, we investigate three distinct but interrelated problems for nonparametric analysis of clustered data and multivariate data in pre-post factorial design. In the first project, we propose a nonparametric approach for one-sample clustered data in pre-post intervention design. In particular, we consider the situation where for some clusters all members are only observed at either pre or post intervention but not both. This type of clustered data is referred to us as partially...
