The Relationships Between Sleep Quality, Health-Related Quality Of Life, And Injury In High School Student Athletes, Karleigh Kirsch

College of Graduate Studies: Theses & Dissertations

Various physiological and lifestyle factors make shorter sleep durations more prevalent in young people, leaving them at risk of sleep deprivation. In addition to overall poorer health outcomes and decreases in well-being, lack of sleep has known effects on performance, neurocognitive functioning, and recovery from exercise. This creates a greater potential for sport-related injury to occur. The purpose of this study was to investigate the relationships between sleep quality, health-related quality of life, and injury in high school student athletes. The sample consisted of 100 high school athletes (M age = 15.86, SD = 1.25 years). Participants completed a …

The Influence Of Faculty Peer Network Communication In The Diffusion Of A Centralized Cure, Nicole L. Scheuermann

College of Graduate Studies: Theses & Dissertations

Course-based undergraduate research experiences (CUREs) provide students the benefits of undergraduate research participation by incorporating authentic scientific research into laboratory courses. CUREs are a relatively young pedagogy and are therefore innovative. Roger’s (2003) diffusion of innovations (DOI) framework posits that the diffusion of innovations, such as CUREs, is a highly social process. Most existing CURE research has focused on the impacts to students and the critical elements of CURE design. Investigation into instructor peer network communication is largely absent from the existing CURE literature. This study investigates the structure and function of a CURE community – the Malate Dehydrogenase CURE …

Mortality In Interspecific Hybrids Of Nasonia Vitripennis And Nasonia Giraulti, Bonnie Cobb

College of Graduate Studies: Theses & Dissertations

Nasonia is a parasitoid wasp genus that serves as an emerging model for studying speciation due to an incompatibility between nuclear and mitochondrial genomes between sister taxa. Short generation times, easy rearing in a lab setting, producing large amounts of progeny, and whole genome sequencing make Nasonia is an excellent candidate for studying incomplete reproductive isolation. Nasonia have five chromosomes and exhibit haplo-diploid sex determination in which fertilized eggs develop into diploid females and unfertilized eggs develop into haploid males. Recessive phenotypes are hidden in diploid females but are laid bare in haploid males as there is no interaction between …

Investigating The Effect Of A Facultative Symbiont, Hamiltonella Defensa, On Pea Aphid, Acyrthosiphon Pisum, Fecundity And Behavior In Elevated Co₂ Atmospheres, Tyler J. Follman

College of Graduate Studies: Theses & Dissertations

As atmospheric carbon dioxide (CO₂) levels continue to rise, it is important to study how economically important organisms, like the pea aphid, Acyrthosiphon pisum, will react to these conditions. The pea aphid feeds on the phloem of crop plants like alfalfa, peas, and fava beans, where it not only directly harms the plant but also can spread plant viruses. A wide variety of factors can influence pea aphid fecundity and behavior. Some of these factors are abiotic, like atmospheric conditions, and some are biotic, like microorganisms with which the pea aphid has a mutualistic relationship. In this thesis, …

Correlates Of Risky Sexual Behaviors Among African American Females In Juvenile Detention Centers, Eghosa E. Asemota

College of Graduate Studies: Theses & Dissertations

Introduction: In comparison to other demographics, research shows that African American female adolescents are over-represented in the United States Juvenile Justice System. Studies in this vulnerable population demonstrate higher rates of engagement in unsafe sex, and its attendant negative consequences of HIV infections, sexually transmitted diseases, and mistimed pregnancies. There is a paucity of studies that have specifically examined risky sexual behaviors amongst African American females in Juvenile Detention Centers. Objective: The aim of this study is to assess the relationship between the individual, family, peer, and societal factors, and engagement in risky sex among Black female detainees in Juvenile …

The Synthesis And Biocatalytic Reduction Of Beta-Keto Alkynes, Rhema M. Francis

College of Graduate Studies: Theses & Dissertations

The preparation of enantiopure homopropargyl alcohols (but-3-yn-ols) is of high importance to the scientific community. They are employed as valuable pharmaceutical intermediates and are opportune to generate antiviral nucleoside analogues. Chiral inducement of these molecules thus far has been poor (low ee) and has constituted a key challenge for asymmetric synthesis in the last few decades. Enzyme-catalyzed enantioselective reductions of ketones have become popular to produce thus-prepared synthons on an industrial scale. Among them, biocatalysts (dehydrogenases, reductases) emerge as a biodegradable option for chemical transformations, in comparison to chiral catalysts that employ highly toxic metals. This research investigates the catalytic …

Non-Inferiority Testing: Kernel Estimation And Overlap Measure, Larie C. Ward

College of Graduate Studies: Theses & Dissertations

In non-inferiority testing, the decision of whether a proposed treatment is non-inferior to a reference treatment depends on model assumptions and choices of acceptable tolerance limits. Here, we consider a method that employs kernels to estimate the probability density functions of both the experimental and reference populations from two independent samples. Based on these densities, we introduce a quantity called the overlap coefficient or overlap measure. A bootstrap technique is helpful in exploring the distribution and variance empirically. We derive the distribution of this measure and define a hypothesis test that can be applied to the non-inferiority setting under some …

The Need For Social Support From Law Schools During The Era Of Social Distancing, Michele Okoh, Inès Ndonko Nnoko

Law students have been faced with unparalleled stress during the syndemic. They must cope with being students during the COVID-19 pandemic but also must deal with stress related to social and political unrest. This essay recommends that law schools apply social support theory in developing interventions to effectively address the needs of law students now and in the future.

Social support theory focuses on the value and benefits one receives from positive interpersonal relationships. These positive relationships impact both mental and physical health and promote beneficial short and long-term overall health. However, not all supports are the same, and social …

Common Use, Lineage, And Lethality, Darrell A. H. Miller, Jennifer Tucker

Faculty Scholarship

Political and legal debates over assault rifles, large-capacity magazines, and other lethal technology are characterized by increasing rancor and hostility. Lack of a common vocabulary to describe the topics of debate, much less facilitate a constructive dialogue, only aggravates this trend. Sorely missing from the current debate is a shared vocabulary for what the public policy and the constitutional doctrine are aiming to achieve. Part I of this Article outlines the state of Second Amendment doctrine with respect to which and what type of arms are protected, and the confused language and goals of that doctrine. Part II provides a …

Structural And Functional Characterization Of Two Poly(Aspartic Acid) Hydrolases, Amanda Jansch

College of Graduate Studies: Theses & Dissertations

Due to the accumulation of polymers in the environment, biodegradable alternatives should be used in place of commonly used polymers like poly(carboxylates). Poly(carboxylates) are water-soluble polymers (WSPs) that make up a variety of consumer products, such as detergents, descaling agents, and superabsorbent materials commonly found in diapers and feminine hygiene products. While the visible accumulation of these products may not be obvious, it is necessary to reduce the amount entering the environment. Poly(aspartic acid) (PAA) is an alternative WSP that is biodegradable through the action of three different enzymes, PahZ1_KT-1, PahZ2_KT-1, and PahZ1_KP-2. Originally …

Synthesis Of Functionalized Aromatic Heterocyclic Compounds And Its Applications In Organized Self-Assemblies, Emmanuel T. Fasusi

College of Graduate Studies: Theses & Dissertations

1,2,3-triazoles due to their structure, possess good optical properties and are capable of molecular recognition by their supramolecular capabilities of utilizing weak forces of interaction (such as hydrogen bonding, dipole interaction) in establishing a close association with targets. They are easy to synthesize, which opened the opportunity for a wide pharmaceutical application, mostly as pharmacological scaffolds. However, challenges such as poor water solubility, inefficient drug delivery and increased toxicities due to frequent dosing of drugs are commonly faced which reduces the efficacy of the drugs. It is therefore important to have “delivery vehicles” which could help transport the drugs to …

States' Public Health Funding And Population Health Outcomes: An Examination Through A Socio-Ecological Lens, Maureen K. Akubu-Odero

College of Graduate Studies: Theses & Dissertations

The US public health system has been underfunded for decades, despite its significant mandate of improving overall population health outcomes. This ecological study evaluates the association between state public health funding and population health outcomes and the role of state public health funding in reducing state-level health disparities. The findings show that the relationships between public health investments and improvements in health outcomes and health disparity in states are moderated by socioeconomic contextual factors. The findings suggest a need for continued and increased public health investments, tailored to community needs and context

Among these BMPs, bioslope has been becoming more popular due to its applicability for roadway embankments and areas with limited ROW constraints. It removes pollutants effectively by physical filtration and chemical adsorption …

Nitrate Removal During The Shoulder Months In The Occoquan Reservoir: A Comprehensive Study, Km Risaduzzaman

College of Graduate Studies: Theses & Dissertations

The artificial nitrate addition by the Upper Occoquan Service Authority (UOSA)’s Water Reclamation Facility (WRF) to the Occoquan Reservoir during the warmer months has been proven to be an efficient way of maintaining the water quality of the reservoir. During the warmer months, the water body became thermally stratified, resulting in hypolimnetic anoxia and the subsequent release of undesired matters from the reduced sediments. At the end of the warmer months, the temperature began to decrease, and by the beginning of winter, oxygen became ubiquitous in water because of fall turnover. This condition remained stable until the following thermal stratification; …

Applying Conservation Genomic Techniques To Guide Management Of The Reticulated Flatwoods Salamander (Ambystoma Bishopi), Miranda Gaupp

College of Graduate Studies: Theses & Dissertations

The Reticulated flatwoods salamander (Ambystoma bishopi) is a federally endangered amphibian endemic to the longleaf-pine ecosystem of the southeastern U.S. This study used analyses of single-nucleotide polymorphism (SNP) data, collected from 2,255 unique individuals across 5 breeding seasons, spread across the known extant range of A. bishopi, to characterize the genetic diversity and demographics of populations, genetic relationships among populations, and patterns and spatial extents of gene flow, and to evaluate potential effects of management on A. bishopi’s resiliency.

Epigenetic Buffering In Introduced House Sparrows, M. Ellesse Lauer

College of Graduate Studies: Theses & Dissertations

Epigenetic buffering, as an environmentally induced increase in variance of epigenetic states that increases phenotypic variation to buffer populations against decreased fitness, may be a factor that resolves the genetic paradox of introduced species. DNA methylation is a molecular mechanism that could facilitate epigenetic buffering by changing in response to environmental stress. Therefore, epigenetic buffering can be detected through increased variance in DNA methylation in novel or heterogeneous environments. Introduced house sparrows (Passer domesticus) have well-documented phenotypic changes with low genetic diversity, high epigenetic diversity, and high variance in DNA methylation that provide a characteristic signature of epigenetic buffering. …

Neosublime, Reframing The Philosophical, Kathy Varadi

College of Graduate Studies: Theses & Dissertations

Why have the sunsets and sunrises become so amazingly colorful and awe inspiring recently? Eighteenth century philosophers said such events were examples of the sublime. They defined the sublime as that which is the most absolutely great combined with an underlying element of fear usually caused by the actions of God. This infers that the sublime is something that you can’t fully understand or wrap your head around and leaves you speechless and spell bound. Contemporary art critics say that the sublime is no longer applicable to art because it has been overused. I disagree, and in my art, I …

Behavior And Chemical Signals As Markers Of Colony Identification In Argentine Ants (Linepithema Humile), Stephanie A. Rohrbach

College of Graduate Studies: Theses & Dissertations

Argentine ants, Linepithema humile, are a highly successful invasive species around the globe and are especially prominent in states such as California and the southeastern United States. L.humile have a unique form of unicoloniality, called “supercolonies”. L. humile can detect colonymates through scent markers in their outer cuticle. With these chemical markers, ants will exhibit high aggression if they smell different from one another. In our study, we performed aggression assays among ten different nest sites and analyzed their CHCs through gas chromatography mass spectrometry, or GC-MS, analysis. For our behavior results, while within-nest interactions displayed low aggression as …

Modelling Muscle Activation Using Emg Signal, Mercy U. Okonna

College of Graduate Studies: Theses & Dissertations

(EMG) is a method for measuring muscle activity by an electrical signal, and is useful in studying motor control, postural control, and in physical therapy. A current research topic is creating an algorithm that can use the EMG signal to reliably classify a muscle as active or inactive. This thesis presents a classification algorithm for leg muscles with a single activation spike while walking.

The algorithm is based on moving averages and a convex combination of mean signal strength in active and inactive …

Hemocyte-Mediated Immune Response To A Bacterial Infection In The Cat Flea (Ctenocephalides Felis), Melanie Muñoz

College of Graduate Studies: Theses & Dissertations

Despite their continued medical and veterinary importance, the vectorial capacity of fleas (Order Siphonaptera) is often underestimated. Fleas are best described as ectoparasites of a variety of mammalian and aviary hosts. In humans, fleas are infamous for the transmission of several detrimental agents, including those that cause plague, murine typhus, and cat-scratch disease. Although their significance in flea immune responses remains unknown, phagocytic immune cells, known as hemocytes, are important players in the cell mediated immune response of insects. Among invertebrates, hemocytes provide defense against foreign microbes via phagocytosis, cellular encapsulation, and the production of humoral immune factors. As mentioned …

Ecology Of Black-Legged Ticks (Ixodes Scapularis) At Fort Drum Military Installation, New York, Lucas Eli Price

Graduate Theses, Dissertations, and Problem Reports (ETD)

The number of confirmed cases of Lyme disease in the United States of America has risen from 12,801 cases reported in 1997, which is the earliest year these data are available, to 23,453 confirmed cases in 2019. In the eastern United States, black-legged ticks (Ixodes scapularis) are the primary vector of Lyme disease, which is caused by the spirochete bacterium, Borrelia burgdorferi. Tick abundance tends to be highest in dense forest habitats and where wildlife diversity is low. Because wildlife species have varying levels of competency as reservoir hosts, sources of tick bloodmeals influence Lyme disease ecology. …

Eco-Material Rifts In South Asian Anglophone Fiction, Muhammad Manzur Alam

Graduate Theses, Dissertations, and Problem Reports (ETD)

I examine how South Asian Anglophone fiction represents the evolution and derangement of postcolonial ecologies, especially how unrelenting colonial and capitalist interventions affect the symbiotic relationship between subaltern people and nonhuman entities. The conceptual methodology develops from Karl Marx’s theory of “metabolic rift,” which illustrates how capitalist exportation of crops causes loss of important soil nutrients because the nutrients are consumed in distant locations and not returned to the original soil. My concept of “eco-material rifts” extends Marx’s idea to contend that the “rifts” have grown into more complicated and difficult to remediate modes of material rifts today. I scrutinize …

Factors Influencing Brook Trout Population Dynamics And Resilience In Central Appalachian Headwater Streams, Christopher W. Schwinghamer

Graduate Theses, Dissertations, and Problem Reports (ETD)

Central Appalachia has a unique history of human perturbation due largely to its historical economic reliance on extractive industry and timber harvest. Legacy impacts from these historic disturbances along with contemporary stressors in the form of continued industry, changing climates, altered land use, habitat fragmentation, and introduced species can present great threats to the region’s aquatic ecosystems. Brook Trout Salvelinus fontinalis are a species that has recreational and economic importance to the communities of central Appalachia but declines in size and abundance have been observed.

Analyzing The Viability Of Direct Pcr For Use In Conjunction With Cyanoacrylate Enhanced Fingerprints, Coral M. Smith

Graduate Theses, Dissertations, and Problem Reports (ETD)

Efficient methods for DNA analysis are desperately needed in laboratories due to the influx in DNA analysis requests. The current DNA processing methods are costly, time consuming, and involve multiple tube changes, increasing the risk of contamination. However, the use of direct PCR can simplify the DNA analysis process by eliminating the extraction, purification and quantitation steps. Presently, the FBI Quality Assurance Standard 9.4 requires all evidence samples to be quantitated. As a result, the direct PCR method of DNA processing cannot be implemented on evidence samples at this time. Direct PCR presents the opportunity to provide efficient DNA analysis, …
