Genetic Relationships Using Mitochondrial Versus Nuclear Markers: Is The Catfish Rag1 Gene Suitable For Species Differentiation In The Family Pangasiidae?, Huong Thanh Hoang

Graduate Theses and Dissertations

The Mekong River located in Southeast Asia is a global “hotspot” for aquatic biodiversity. It includes an extensive variety of fish species second only to the Amazon River in South America. Recent studies have revealed the impacts of anthropogenic and climate factors on this river system. Such impacts can result in the formation of barriers, which divide a species population and impede gene flow between separated sub-populations. Barriers influence evolutionary trajectories resulting in the generation of geographic variants or subspecies from an ancestral population. Catfish (Teleostei: Siluriformes) are a key species of the Mekong River ecosystem and are an essential …

Evidence has shown that certain cover crops can increase beneficial insects and suppress disease in the following cash crop. They can also provide important resources to pollinators. In order to build a better understanding of …

Chasing The Genetics Of Ascites In Broilers Using Whole Genome Resequencing, Alia Parveen

Graduate Theses and Dissertations

We are using whole genome resequencing to identify chromosomal regions associated with resistance or susceptibility to ascites, a form of pulmonary hypertension syndrome, meat-type chickens. Previous Genome Wide Association Studies (GWAS) based on Single Nucleotide Polymorphisms (SNPs) have identified regions on chromosomes 2, 9 and Z. Despite several GWAS and further genotyping, there are no reliable or potential markers for ascites phenotype. We have completed screening of Copy Number Variations (CNVs) and Single Nucleotide Polymorphisms in ascites resistant and susceptible birds from the relaxed, REL, line derived from a commercial elite broiler line. DNA samples from resistant and susceptible birds …

Analyzing Multigene Stacking And Genome Editing Strategies In Rice, Bhuvan Pathak

Graduate Theses and Dissertations

Crop improvement through biotechnology is an integrated effort, incorporating multiple approaches like integration of genes, editing of native genes, and removal of selection marker genes. Before streamlining the protocols, the efficiency and feasibility of the individual approach and their components must be tested. This study evaluated following approaches: 1) stacking an array of genes into a single locus by site-specific integration via Cre-lox recombination in rice, 2) determining the efficiency of I-SceI and the CCR5-ZFN in the targeted excisions of gene fragments in rice and Arabidopsis, and 3) determining the efficiency of CRISPR/Cas9 in generating targeted mutations for genome editing …

Schooling And Civic Behavior: A Global Perspective, Ian Kingsbury

Graduate Theses and Dissertations

National governments confront different challenges to the goal of creating model citizens, as well as different ambitions in the type of citizen that they wish to create. The United States government faces a tension in determining the role of education in shaping the social order. As a liberal democracy that extols the virtue of individual liberty, the United States should allow educational pluralism to flourish. Paradoxically, however, a nation of immigrants might require an education system that turns students into “proper Americans” who honor the precepts of liberty, equality, and self-government. I draw from domestic and international studies to inform …

Anti-Inflammatory Effects Of Cruciferous And Apiaceous Vegetables In C57bl/6j Mice Colon, Rosa Moreno Narvaez

Graduate Theses and Dissertations

Previous studies have demonstrated chemo-preventive potential of cruciferous and apiaceous vegetables against colon cancer. Colon inflammation is one condition closely related with colon cancer initiation. Therefore, we wanted to compare if total western diet (TWD) was as pro-inflammatory as died-induced obesity (DIO) and a better dietary model for human conditions, and determine if diet supplementation with cruciferous (broccoli, watercress and cabbage) or apiaceous vegetables (celery and parsnip) could reduce dietary inflammation, and which vegetable was more effective.

Male CBL57/6J mice were fed chow for seven days, on day eight, mice were assigned to one of the following diets: American Institute …

Assessing The Impact Of 3d Printed Terrain On Teaching Topography In Introductory Earth Science Labs, Jay Alan Cockrell

Masters Theses

Learning to effectively read topographic maps is challenging for students, as these maps contain 3D representations of terrain displayed on a 2D surface map. This project assessed student learning when 3D terrain printed from a portion of the laboratory quadrangle map currently in use was introduced into an earth science course for non-science majors. Using a quasi-experimental design with nonequivalent groups across two semesters, performance on the Modified Topographic Map Assessment (MTMA) administered as a pre- and posttest was used to compare learning outcomes between the traditional lab and the 3D print lab intervention. Students in the traditional (n = …

An Evaluation Of Unmanned Aerial Systems And Structure-From-Motion For Fluvial Large Wood Sensing And Risk Assessment, Daniel Gerke

Masters Theses

This research aims to show Unmanned Aerial System (UAS) and Structure-from-Motion (SfM) technology can, in combination, improve on traditional large wood (LW) monitoring techniques. More temporally and economically efficient data collected at a finer spatial resolution and greater spatial extent will increase the effectiveness of management plans and risk assessment for LW by providing decision-makers with a complete picture of the river.

Contemporary practices are too inefficient in time and labor for large-scale monitoring of fluvial LW with anything more than the most general management or risk assessment in mind. The paradigm of river research, the river continuum concept (RCC), …

Finding And Analyzing De Novo Mutations In The Exomes Of Parent-Offspring Trios Of Spontaneous Chiari Malformation Type 1 Patients, Brian Leon Ricardo

Arts & Sciences Graduate Student Theses and Dissertations

Chiari Malformation Type 1 (CM1) is a neurodevelopmental disorder that occurs when one of the cerebellar tonsils herniates past the foramen magnum causing headaches, motor or sensory deficits, sleep apnea, and difficulty swallowing. This disorder is estimated to affect 1% of the population but due to the need of neuroimaging for diagnosis and the presence of asymptomatic patients there is still uncertainty about the exact proportion of the population affected. CM1 often presents itself with other neurodevelopmental disorders such as syringomyelia, scoliosis, and known genetic syndromes such as Klippel-Feil and Marfan syndromes. Twin, family, and familial clustering studies have established …

The Quiet Classroom Game With An Indiscriminable Contingency In A High School, Stefanie Schrieber

Master's Theses

The Quiet Classroom Game (QCG) is an interdependent group contingency utilized to decrease classroom noise levels, increase student engagement, and decrease disruptive behaviors in the classroom setting. The purpose of the current study was to investigate the effects of the QCG in three high school classrooms in the Southeastern United States. Classrooms were recruited based on teacher reports of excessive noise and high rates of disruptive behavior. A multiple baseline design with two intervention phases was utilized to examine the effects of the intervention. The first phase was the QCG alone, and the second phase was the QCG with an …

Localized Method Of Approximate Particular Solutions For Solving Optimal Control Problems Governed By Pdes, Kwesi Acheampong

Master's Theses

In this thesis, the method of approximate particular solutions(MAPS) and localized method of approximate particular solutions(LMAPS) with polynomial basis, and radial basis functions are proposed and applied on the optimal control problems(OCPs) governed by partial differential equations(PDEs).

This study proceeds in several steps. First, polynomial basis and radial basis functions are used to globally approximate solutions for the PDEs which have been combined into a single matrix system numerically from the optimality conditions of the OCPs. Secondly, polynomial and radial basis functions are used to locally approximate particular solutions for the same matrix system numerically. We use these approaches to …

Processing Speed For Action And Semantic Memory, Tyler A. Surber

Master's Theses

Previous research suggests that the processing of affordances may require more perceptually relevant information than words can provide (Surber et al., 2018; Chainay & Humphreys, 2002). The present study investigates this hypothesis with the shoebox task used in Bowers and Turner (2003). A list of 81 object nouns (targets) and associated features (primes: affordance, semantic, and non-associates) was compiled from the McRae, Cree, Seidenberg, and McNorgan (2005) norms. Affordances denote possibilities for action in relation to the object (e.g. chair – sit), whereas semantic features indicate definitional characteristics (e.g. chair – has legs). Affordances and semantic features served as primes …

Localized Method Of Approximate Particular Solutions For Solving Fourth-Order Pdes, Lionel Amuzu

Master's Theses

In the past, dealing with fourth-order partial differential equations using the Local Method was not reliable due to difficulties in solving them directly. An approach such as splitting these equations into two Poisson differential equations was adopted to alleviate such challenges. However, this has a limitation since it is only applicable to Dirichlet and Laplace boundary conditions. In this paper, we solve fourth-order PDEs directly using the LMAPS. The improvement on the accuracy of this method was as a result of the proposed distribution of boundary conditions to alternating boundary points. And, also the use of suitable shape parameter; calculated …

Multi-Point Flux Approximations Via The O-Method, Christen Leggett

Master's Theses

When an oil refining company is drilling for oil, much of the oil gets left behind after the first drilling. Enhanced oil recovery techniques can be used to recover more of that oil, but these methods are quite expensive. When a company is deciding if it is worth their time and money to use enhanced oil recovery methods, simulations can be used to model oil flow, showing the behavior and location of the oil. While methods do exist to model this flow, these methods are often very slow and inaccurate due to a large domain and wide variance in coefficients. …

Distribution, Abundance, And Trophic Ecology Of Anguilliform Leptocephali In The Northern Gulf Of Mexico, Lillian Collins

Master's Theses

All species of anguilliform eels have pelagic leptocephalus larval stages, which provides a means of monitoring the population dynamics of these otherwise cryptic and hard to study species. The goals of this study were to: 1) describe the distribution and abundance of anguilliform eel leptocephali across the northern Gulf of Mexico, and 2) examine the trophic ecology of leptocephali using stable isotope values of carbon and nitrogen (δ13C and δ15N). A 25-year (1990-2014) ichthyoplankton dataset provided by the National Oceanic and Atmospheric Administration (NOAA) Southeast Area Monitoring and Assessment Program (SEAMAP) was used to examine interannual variations in leptocephalus distribution, …

Changes In Antarctic Bottom Water Formation During Interglacial Periods, Samuel Glasscock

Master's Theses

In the modern Southern Ocean and during the last interglacial period, Marine Isotope Stage 5, there are observations that point to reduced Antarctic Bottom Water (AABW) formation. These reductions are believed to be driven by an increase in the strength of the Southern Ocean density stratification due to surface water freshening. Any reduction in AABW formation has important implications for global climate as AABW plays a vital role in the cycling of carbon in the world’s ocean. The primary question this study seeks to answer is do these AABW reductions occur during any of the other interglacials of the past …

The Thiol Specific Antioxidant (Tsa1) Gene Is Required For Survival In Macrophages And Oxidative Stress Resistance In Histoplasma Capsulatum, Lauren Kennedy

Master's Theses

Histoplasma capsulatum(Hc) is a pathogenic fungus that causes one of the most common invasive fungal respiratory diseases, Histoplasmosis. Histoplasmaundergoes a dimorphic shift from mold to yeast which is crucial to pathogenesis of the organism.

The thiol specific antioxidant gene, Tsa1,is strongly upregulated in the yeast (pathogenic) morphotype. This data led to the hypothesis that this gene plays a role in protecting Hcfrom host mediated oxidative attack. To characterize Tsa1 function, a knockdown strain (tsa1-RNAi) was created by RNAi gene silencing. Expression of Tsa1in the tsa1-RNAistrain was reduced to 10% that …

The Variability Of High-Frequency Motions And Their Interactions With The Mesoscale On The Mississippi Shelf, Jordan Earls

Master's Theses

In this study, we examine the spatial and temporal variability of high-frequency and low-frequency motions across the Mississippi Shelf and how the high-frequency motions are modulated by low-frequency mesoscale motions. For this purpose, we use Acoustic Doppler Current Profiler (ADCP) measurements collected at nearshore (23 m), mid-shelf (60 m), and shelf break (88 m) stations. High-frequency motions are defined as motions with periods less than 36 hours, whereas mesoscale motions have larger periods. The collected datasets are analyzed through bandpass filtering, least square harmonic analysis, spectral analysis, and empirical orthogonal functions (EOF). We find that along-shelf barotropic mesoscale motions contain …

Development And Employment Of Environmental Dna Methods For The Detection Of Bull Sharks (Carcharhinus Leucas) In A Freshwater And Estuarine Interface In The Mobile-Tensaw Delta And Mobile Bay, Alabama, Katherine Schweiss

Master's Theses

Species conservation and management is influenced by the quality of monitoring methods employed, especially when targeting elusive, but ecologically significant species, like elasmobranchs. Bull Sharks (Carcharhinus leucas) are highly mobile predators that rely on estuaries and freshwater rivers for maturation, resources, and refuge; their ability to withstand changing environmental conditions may mean they are linking ecosystems through their habitat usage and movements. Rather than setting nets or attaching acoustic monitoring devices, which can be expensive, time-consuming, and invasive, the analysis of environmental DNA (eDNA) for tracing species presence was used to target C. leucasDNA. The present research …

Early Recruitment Of Crassostrea Virginica To Restored And Natural Oyster Reefs In The Western Mississippi Sound: Larval Supply And Post-Settlement Success, Leah Morgan

Master's Theses

The eastern oyster (C. virginica) is a foundation species that improves water quality, protects shorelines, provides refuge for other organisms, and contributes to commercial fisheries. Successful early recruitment of eastern oyster is vital for resupplying adult populations in the face of habitat loss. Coastal oyster populations are challenged by freshwater input, hypoxia, predation and overfishing. Consequently, substantial efforts have been dedicated toward oyster restoration within the northern Gulf of Mexico. The overall objective of this study was to consider the role and importance of early recruitment to oyster restoration in western Mississippi Sound. During the summer 2018 recruitment period, we …

Elevated Adhd Symptoms As A Predictor Of Rule Violations Among Male Juvenile Offenders, Kathleen Lolley Ramsey

Master's Theses

Youth with ADHD are disproportionately at-risk for engaging in criminality and aggression relative to the general population, and this may be a function of underlying executive function deficits associated with self-regulation. More specifically, youth with ADHD may be susceptible to difficulties with behavioral regulation (impulsivity) and emotional regulation (e.g., managing feelings of anger). The current study sought to expand on previous research to examine the relationship between ADHD symptoms and aggression and the potential moderating effects of anger control among institutionalized youth. Archival data comprising a sample (N=119) of male adolescents who were admitted to a maximum-security residential facility were …

Archaeobotanical Analyses Of The Winterville Mounds Site (22ws500) And Other Southeastern Ceremonial Complexes, Dana Hauffe

Master's Theses

The prehistoric Southeast region of the United States has had very limited archaeobotanical research focused on botanicals’ medicinal or ritualistic characteristics. An analysis of reported botanical remains recovered from Winterville Mounds (22WS500) and seventy- two other Late Woodland and Mississippian sites, from seven states, was conducted to identify their potential medicinal and ritual use of seventy-five botanicals based on reported ethnobotanical evidence. By classifying botanicals into four classes, modeled after the dissertation of Dr. Michele Williams in 2000, taxon frequency and feature ubiquity is configured and utilized to identify the possible ceremonial and medicinal use plants. At Winterville Mounds Site …

Effects Of Water Table Depth And Edaphic Characteristics On Plant Diversity In A Southern Mississippi Pitcher Plant Bog, Patrick Kirby

Master's Theses

This study examined the effects that water table depth and soil characteristics have on plant species richness and species composition within pitcher plant bogs across seasons. Eight piezometers were installed at random distances to monitor long-term water table depth and pressure fluctuations along a ~710-meter line transect traversing upland and bog habitats. Vegetation sampling quadrats (n=128) were set up near each piezometer. Cover data and water table depths were collected in spring and late summer. Soil samples collected from each treatment group were used to obtain soil texture and nutrient data. The summer collection period yielded a total gdiversity of …

Expanding The Fear Of Loss Of Vigilance Theory: Using Intolerance Of Uncertainty, Responsibility For Harm, And Fear Of Sleep To Predict Nocturnal Panic Attacks, Nicole S. Smith

Master's Theses

Nocturnal panic involves experiencing panic attacks out of a sleeping state without obvious causes such as nightmares or loud noises. Roughly half of patients with panic disorder will experience nocturnal panic in addition to panic attacks while awake, or daytime panic. Like daytime panic, nocturnal panic also occurs in other disorders such as PTSD. The Fear of Loss of Vigilance theory is currently the only model available to explain nocturnal panic. It suggests that nocturnal panickers fear states in which they cannot easily react to or protect themselves from danger. Prior research using a self-report measure to differentiate nocturnal and …

Estimating Body Mass Through Bone Mineral Density Studies Using Dexa (Dual-Energy X-Ray Absorptiometry), Kaitlin Harstine

Master's Theses

Identification of a decedent is one of the primary goals of forensic anthropologists. In order to do this, one must build a biological profile based on the remains that are provided. Sex, age, ancestry, and stature are four of the most common, however a fifth addition piece of information that could be beneficial is body mass. The goal of this research is to explore the relationship between bone mineral density (BMD) and body mass, using data collected from dual x-ray absorptiometry (DEXA) scans of 107 collegiate football athletes. Athletes are a good fit for this study because they have achieved …

The Quiet Cafeteria Game, Mary Ware

Master's Theses

Due to the prevalence of disruptive behavior in schools, educators are required to allocate time and resources to manage student behavior problems (Murphy, Theodore, Aloiso, Alric-Edwards, & Hughes, 2007). Disruptive behaviors take place in the classroom and other non-classroom settings, which can negatively impact the academic success of students. Specifically, noisemaking is a disruptive behavior that educators report as being one of the most concerning disruptive behaviors, thus, increasing the need for effective interventions to address disruptive behavior in non-classroom settings (Sun & Shek, 2012). The current study evaluates the effects of a decibel-level based interdependent group contingency, the Quiet …

Involuntary Signal-Based Grounding Of Civilian Unmanned Aerial Systems (Uas) In Civilian Airspace, Keith Conley

Master's Theses

This thesis investigates the involuntary signal-based grounding of civilian unmanned aerial systems (UAS) in unauthorized air spaces. The technique proposed here will forcibly land unauthorized UAS in a given area in such a way that the UAS will not be harmed, and the pilot cannot stop the landing. The technique will not involuntarily ground authorized drones which will be determined prior to the landing. Unauthorized airspaces include military bases, university campuses, areas affected by a natural disaster, and stadiums for public events. This thesis proposes an early prototype of a hardware-based signal based involuntary grounding technique to handle the problem …
