My Child’S Keeper: Child Vulnerability And Quality Of Life On Parental Stress And Grit, Abigail Armstrong

Master's Theses

There is a reciprocal relationship between parenting stress and child distress that has been well documented (e.g., Rechenberg, Grey & Sadler, 2017). These effects generalize to physical outcomes such that higher maternal depression has been associated with poorer child health-related quality of life (HRQOL; Jaser, Whittemore, Ambrosino, Lindemann, & Grey, 2008). In the same way that parental distress has been shown to affect the child, parental perceptions of child vulnerability in children with chronic illness has also been associated with negative outcomes, including child depressive symptoms (Mullins et al., 2004), increased health care use (Spurrier et al., 2000), and increased …

Development And Use Of An Environmental Dna Tool To Monitor Recovery Of The Critically Endangered Smalltooth Sawfish, Pristis Pectinata, In The Northwest Atlantic, Ryan N. Lehman

Master's Theses

The Critically Endangered Smalltooth Sawfish, Pristis pectinata, was once common in the tropical and subtropical waters of the Atlantic Ocean; however, following global declines in range and abundance over the past century, individuals were restricted to the waters of south and southwest Florida (SWFL) by about the 1980’s. Recently, public encounter reports have emerged in historically occupied habitats in United States waters, suggesting individuals are present in, or re-occupying, these areas, although the status of P. pectinata outside of SWFL is not currently well understood. Targeted environmental DNA (eDNA) surveys were chosen to assess the occurrence of P …

Exploring Dissociation As A Facilitator Of Suicide Risk Using Virtual Reality, Nicole Caulfield

Master's Theses

Research shows that suicidal behavior is not a result of a single cause or single event, but instead is an interaction of facilitators. One potential facilitator that needs further exploration is dissociation. Dissociation has been consistently linked to suicidal behavior, and treatment for dissociative disorders seem to be associated with a reduction of suicidal ideation and suicide attempts. Prior theories have posited that dissociation increases the possibility of a suicidal act because of intensified disconnect from the body. However, these theories do not indicate whether dissociation is a facilitator of suicide risk by increasing suicidal ideation, attempt behaviors, and capability …

Assessment Of Genetic Diversity In Largetooth Sawfish, Pristis Pristis, Populations Over The 20th Century, Ann Fearing

Master's Theses

The Critically Endangered Largetooth Sawfish, Pristis pristis, experienced global declines in range and abundance over the past century and Australia is now their last stronghold. This research aimed to understand whether these declines have been accompanied by a reduction in levels of genetic diversity. Using P. pristis tissue samples sourced from natural history specimens, three fragments (616-bp, 386-bp, 141-bp) in the mitochondrial DNA (mtDNA) control region were PCR-amplified. At each fragment, significant genetic structure was found in P. pristis overall (Φ_ST=0.946, N=9; 0.813, N=54; 0.771, N=99). The Indo-West Pacific and Atlantic/Eastern Pacific each harbor genetically distinct lineages of …

Hate Speech, Habitus, And Identity Signaling On 4chan’S Politically Incorrect Board, Jonathon Geiger

Master's Theses

Websites, such as 4chan, have provided a place for extremism and hate speech to flourish through anonymous discourse. One group that has been especially important to this growth has been the alt-right. The alt-right is a far-right white nationalist movement that is known for engaging in trolling, creating memes, and generating conspiracy theories. Past research has focused on the amounts of hate speech and characterizing content on the website. However, past studies have not looked at the experience of using the website through the combination of participant observation and content analysis. Here I show that the extensive use of hate …

Nutrition At Tipu: A Comparative Analysis Of Juvenile Health In Maya Populations, Sydnie A. Bianchi

Master's Theses

The site of Tipu in west central Belize provided a foothold for Spanish missionaries in the 17^th century. The effects of contact on adults among the 550 burials recovered in the cemetery there have been well studied, but the children have received less attention. Therefore, this study examined juvenile health through four markers: Linear Enamel Hypoplasia (LEH), a non-specific marker of health disruptions; Porotic Hyperostosis (PH), an indicator of anemia; and Periostitis, an indicator of infection. Some 131 individuals were evaluated using criteria developed by Steckel, Sciulli, and Rose (2002). The results were compared to Late Classic Copán (Storey, …

The Impact Of A Casve-Cq Enhanced Intervention On Group Career Counseling Outcomes, Kendall L. Klumpp

Master's Theses

This study aimed to investigate the effect of using the CASVE Cycle Questionnaire (CASVE-CQ) on career group intervention outcomes, specifically career decidedness, negative career thoughts, career decision-making difficulties, and career decision-making self-efficacy. Participants included 45 undergraduate students who receive scholarships from a student retention program which includes a career group intervention as a requirement to receive the scholarship. It was predicted that the use of the CASVE-CQ would result in greater increases in career decidedness and career decision-making self-efficacy, as well as greater decreases in negative career thoughts and career decision-making difficulties compared to those receiving the same intervention that …

Investigating The Timing Of Initial Louann Salt Flow And Its Relationship With The Gilbertown Fault Zone, Southwest Alabama, Avery Rosenbalm

Master's Theses

The Mesozoic Louann Salt extends through the northern GOM, extending onshore from eastern Texas to western Alabama and Florida. Along the landward terminus of the salt is a system of peripheral faults, including the Gilbertown Fault Zone bordering the Mississippi Interior Salt Basin to the north and east. This study sought to constrain the timing of fault movement and determine its relationship to the baswinward evacuation of Louann Salt through the use of a 3D seismic survey and well logs. By mapping Mesozoic formations and the peripheral fault system, lateral changes in formation thickness were used to generate fault expansion …

Rapid Implicit Diagonalization Of Variable-Coefficient Differential Operators Using The Uncertainty Principle, Carley Walker

Master's Theses

We propose to create a new numerical method for a class of time-dependent PDEs (second-order, one space dimension, Dirichlet boundary conditions) that can be used to obtain more accurate and reliable solutions than traditional methods. Previously, it was shown that conventional time-stepping methods could be avoided for time-dependent mathematical models featuring a finite number of homogeneous materials, thus assuming general piecewise constant coefficients. This proposed method will avoid the modeling shortcuts that are traditionally taken, and it will generalize the piecewise constant case of energy diffusion and wave propagation to work for an infinite number of smaller pieces, or a …

A Call To Arms: A Comparative Study Of Mississippi And Kentucky Citizens During The Secession Crisis, 1859-1861, Amy Myers

Master's Theses

Many studies of the American Civil War have considered why Mississippi leaders voted to secede, while Kentucky politicians remained in the Union. Scholars have previously focused on political elites to understand the underlying motivations behind each state’s decision. These same scholars have often confined their studies to a synthesis of why secession occurred nationally or at the state level. The question remains as to what the common citizen saw and believed when faced with secession and if their views matched their delegates.

This study utilizes the governors’ papers of John J. Pettus and Beriah Magoffin, the Jefferson Davis papers, and …

Contribution Of Submarine Groundwater Discharge To Select Biogeochemical Fluxes In St. Louis Bay, Mississippi, Haley Spaid

Master's Theses

This thesis assesses the role of submarine groundwater discharge (SGD) in St. Louis Bay, Mississippi. Located along the northern Gulf of Mexico, St. Louis Bay (SLB) is a semi-enclosed bay that is important to the local area for recreation and tourism. SGD is the movement of any water into the water column across the sediment-water interface. In coastal environments, SGD can be a source of a variety of substances including nutrients and pollutants. In this study, a steady state mass balance approach was used to quantify SGD flux for SLB using ²²³Ra, ²²⁴Ra, and Ba. Using the water …

Microplastic Abundance, Distribution And Impacts On Sargassum-Associated Juvenile Fishes In The Gulf Of Mexico, Olivia Lestrade

Master's Theses

Microplastics are a concern in marine environments because they are highly durable, ubiquitous, and can be mistaken for food and ingested by small organisms. Pelagic Sargassum, an important habitat for larval and juvenile stages of many fish species, is found in large surface aggregations, and may provide complex structure in which microplastics become trapped. This could lead to greater risk of microplastic ingestion by fish early life stages associated with Sargassum habitats. To better understand the impacts of microplastics within Sargassum communities, this study examined 1) microplastic concentrations and ingestion by juvenile fishes associated with Sargassum; 2) the microbial …

Sediment Provenance Of Tsunami Deposits: Implications For Assessing The Relative Intensity Of Paleotsunamis From The Sendai Coastline Of Japan, Tiffany Otai

Master's Theses

The 2011 Tohoku tsunami impacted the northeastern coast of Japan and caused unexpected damages due to the underestimation of this type of hazard. Of particular importance is the fact that geologic evidence for a predecessor event, the Jogan tsunami (CE 869), could have forecasted the severity of the 2011 Tohoku event. While the timing of tsunamis is important for effective hazard mitigation, outside of the 2011 Tohoku event, the intensity of past tsunamis remains unclear. To understand paleotsunami intensity, it is important to document characteristics of modern analogues like the 2011 event. This study utilizes surface distributions of foraminifera from …

Korngold's Dream States: An Analysis Of Transitional Passages In Erich Wolfgang Korngold's Opera "Die Tote Stadt", Tyler Brandon

Master's Theses

This thesis aims to compare Korngold’s treatment of altered states of reality in his 1920 opera Die tote Stadt to that of other composers and apply a theoretical approach to explain the transitions between the diegetic realms, or multiple narrative levels, that the work is contained within. These are outlined by William Cheng in his article entitled “Opera ‘en abyme’: The prodigious ritual of Korngold’s ‘Die tote Stadt.’” An overview of Cheng’s article is provided, recounting the claims that he posits and the analyses that he uses to explain the transitions between these diegetic realms. Next, other instances of altered …

Measuring Implicit And Explicit Attitudes Toward Transracial Adoption, Lillian Spadgenske

Master's Theses

Attitudes toward Transracial Adoption, or TRA (i.e., White individuals adopting a child of a different race than their own) have been largely positive in a few experimental studies conducted, with only one study (Tinkler & Horne, 2011) employing an implicit measure, the Implicit Association Task (IAT). The current study has focused on assessing attitudes toward TRA families with Black versus Asian children using both explicit and implicit (the IAT) measures of bias. In addition, religiosity was tested as a moderator of the attitudes toward TRA adoption. It was found that individuals had much more supportive attitudes toward transracial families on …

Diagonalization Of 1-D Schrodinger Operators With Piecewise Constant Potentials, Sarah Wright

Master's Theses

In today's world our lives are very layered. My research is meant to adapt current inefficient numerical methods to more accurately model the complex situations we encounter. This project focuses on a specific equation that is used to model sound speed in the ocean. As depth increases, the sound speed changes. This means the variable related to the sound speed is not constant. We will modify this variable so that it is piecewise constant. The specific operator in this equation also makes current time-stepping methods not practical. The method used here will apply an eigenfunction expansion technique used in previous …

Assessing The Nursery-Role Function Of Pelagic Sargassum For Juvenile Fishes In The Northern Gulf Of Mexico, Courtney Stachowiak

Master's Theses

Sargassum, a genus of holopelagic brown algae, floats at the ocean’s surface using air-filled bladders and forms a complex comprised of two species, S. natans and S. fluitans. Oceanic processes (e.g., Langmuir circulation, etc.) aggregate Sargassum into mats and weedlines, and primarily distribute the algal complex throughout the North Atlantic Ocean and the Gulf of Mexico (GOM). These floating habitats provide shelter and feeding opportunities for a diverse community of invertebrates and fishes. Sargassum is a presumed nursery habitat for juvenile stages of commercially- and recreationally-targeted fishery species. In this study, I estimated the standardized abundances of juvenile …

Navigating Hate: The Public Deliberation Of Matthew Shepard And Hate Crime Legislation, Abigail Barnes

Master's Theses

Since Matthew Shepard’s murder in 1998, his narrative has been recirculated to justify a federal hate crime statute and Shepard has been used as a symbol for the demand for hate crime legislation. This study seeks to evaluate how Shepard is used in public deliberation, the role of private organizations in the public deliberation of hate crime legislation, and the discursive history of the Shepard-Byrd Hate Crime Prevention Act of 2009. Through a rhetorical criticism, this study finds that the nuances of Shepard’s narrative are abandoned in order to construct him as a “permissible” symbol for LGBTQ+ protections. However, if …

Stability Analysis Of Krylov Subspace Spectral Methods For The 1-D Wave Equation In Inhomogeneous Media, Bailey Rester

Master's Theses

Krylov subspace spectral (KSS) methods are high-order accurate, explicit time-stepping methods for partial differential equations (PDEs) that also possess the stability characteristic of implicit methods. Unlike other time-stepping approaches, KSS methods compute each Fourier coefficient of the solution from an individualized approximation of the solution operator of the PDE. As a result, KSS methods scale effectively to higher spatial resolution. This thesis will present a stability analysis of a first-order KSS method applied to the wave equation in inhomogeneous media.

Validation Of An Inertial-Measurement-Unit System For Calculating Hip And Knee Flexion Angles During Gait, Joonsun Park

Master's Theses

Technological advances regarding Inertial Measurements Units (IMUs) have positioned this type of sensor as an alternative for camera-based motion capture. This study introduces a new IMU based system (IMU_sys) to measure hip and knee flexion angles. PURPOSE: To validate the use of a five-sensor IMU_sys for the measurement of knee and hip flexion angles during gait in adults and pediatrics at two different time points. METHODS: Bilateral hip and knee flexion patterns (LH, RH, LK, and RK) of twenty-two healthy participants (12 adults and 10 pediatric) between the ages of 8 – 35 years were investigated. Participants …

Determining The Trophic Role Of Red Snapper (Lutjanus Campechanus) In Mississippi State Waters Using Stomach Content And Stable Isotope Analysis, Branden Kohler

Master's Theses

The goal of this study was to determine the diet composition, trophic position and ecological role of red snapper (Lutjanus campechanus) in Mississippi state waters utilizing stable isotopes (δ¹³C and δ¹⁵N) and stomach content analysis. Stable isotope analysis of fish and their prey can provide information on species-specific basal resource utilization, diet composition and trophic position which can improve food web models and inform fisheries management decisions. Particulate organic matter (POM), the presumed base of the food web, red snapper muscle tissue, and red snapper stomach contents were collected from 25 sites in 2016 and …

Effects Of Infection Of The Protist Parasite, Dermomycoides Sp., In Dusky Gopher Frog Tadpoles, Jaime Smith

Master's Theses

Infections of the protist parasite, Dermomycoides sp. are thought to have caused several years of low recruitment in the dusky gopher frog (Rana sevosa) populations. I evaluated the effects of density of the infective zoospores, host developmental stage, and tadpoles' ability to acquire resistance to Dermomycoides sp. on dusky gopher frog tadpoles. Tadpoles were exposed to zoospore densities of 0, 250, 500, and 750 zoospores/µL at Gosner stage 25, and we found no significant differences among treatments in tadpole mortality. In evaluating susceptibility by development stage, I exposed R. sevosa to 50 zoospores/µL as eggs, embryos, hatchlings, and …

Assessing The Recalibration Interval For Nearshore Sediment Assemblages After Hurricane Irma: Implications For Developing Long-Term Records Of Overwash Deposits, Stephen Mitchell

Master's Theses

Surface distributions are commonly collected to assist with overwash interpretation; however, many of these are first established immediately after a major overwash event as part of a post-event field survey. This study documents the impacts of Hurricane Irma, a Category 5 storm, on nearshore sediments off the coast of Anegada (British Virgin Islands) using distributions of Homotrema rubra, an encrusting foraminifer with a defined provenance in coral reef ecosystems. Over four sampling intervals spanning 2 years, from six months pre-Hurricane Irma to 18 months post-Hurricane Irma, surface sediment was collected from three shore-perpendicular transects on both the northern and …

Anger, Relational Victimization, And Vengeance In The Context Of Relational Aggression, Alison Poor

Master's Theses

Relational aggression involves the aggressor harming the victim’s social status, reputation, and/or relationships. This form of aggression is a relatively new topic in the literature that would benefit from additional research with emerging adults. The present study examined two models involving relational aggression in a college student sample (N= 247). First, we predicted, based on the general aggression model, that anger rumination would partially mediate the relationship between trait anger and relational aggression. Second, based on the rejection-aggression link, we predicted that vengeance would partially mediate the relationship between relational victimization and aggression. We tested each model separately …

Non-Religious Employee's Perceptions Of Microaggressions And Their Relationship With Job Satisfaction As Moderated By Calling, Jessica Schultz

Master's Theses

The purpose of this study was to investigate the relationships between microaggressions, person-organization fit (P-O fit), job satisfaction, and calling in non-religious individuals. Established research demonstrates that job satisfaction is predicted by P-O fit (Dawis, 2005). Research with minority groups has found that microaggressions are negatively related to P-O fit and job satisfaction (Lyons, Velez, Mehta, & Neil, 2014). However, research has yet to examine these interactions with a non-religious population. Previous investigations have found that calling is positively correlated with both P-O fit and job satisfaction (Duffy & Dik, 2013; Duffy, Allan, & Dik, 2011; Hirschi, 2012), suggesting the …

Does Race Matter? An Examination Of Defendant Race On Legal Decision Making In The Context Of Actuarial Risk Assessments, Riley Davis

Master's Theses

Numerous examples show how consideration of extra-legal factors, like defendant race, in legal decision-making are contributing to the overrepresentation of minorities in the legal system. Because triers of fact may be less familiar with risk assessment results presented by expert witnesses, there is a need to examine how legal decision-making is being affected by race in this context. This study aimed to examine whether individuals are in fact relying on race as a factor above empirically supported expert opinions of actual violence risk predictions. The sample consisted of 280 participants recruited from Amazon’s Mechanical Turk. To test the primary hypothesis …

Creative Expression Through The Gift Of God: The Intertwining Of Creativity And Religion Of The Poor Clares In New Orleans, Louisiana, Maureen Tierney

Master's Theses

This thesis looks at the relationship of art and creativity among the Poor Clares in New Orleans, Louisiana. Through the six sisters, the project addresses the way that religion influences the art that each sister produces. While each sister has had a different experience that drew them to religious life and their artwork, they all agree that their creativity is a gift from God, and this shapes how they engage with their art.

The literature gives an understanding to the role of the artist, and how to understand the nuance in an artist’s choice, when “why” something is produced is …

Finding Identity Through Survival: The Impact Of The Hurricanes In Zora Neale Hurston’S Their Eyes Were Watching God And Jesmyn Ward’S Salvage The Bones, Crystal F. Giles

Master's Theses

This paper attempts to convey the importance of the hurricane symbol in Zora Neale Hurston’s Their Eyes Were Watching God and Jesmyn Ward’s Salvage the Bones. In both novels, the authors use the imagery of setting combined with the characterization of poor women of color in order to emphasize both the effects of environmental disaster on vulnerable communities and also the inherent power of their protagonists to overcome systemic racism combined with natural disaster. The climax of Zora Neale Hurston’s novel revolves around the deadly 1928 Okeechobee Hurricane in Florida, and the rising action of Jesmyn Ward’s novel peaks …

The Wakefield Phenomenon: A Rhetorical Examination Of The Resurgence Of The Anti-Vaccination Movement In The 20th & 21st Century, Karen Boger

Master's Theses

This thesis explores the phenomenon of the anti-vaccination movement and existing publications documenting significant points in its resurgence in the late 20^th and early 21^st century following the now redacted publication by the former Dr. Wakefield asserting a correlation between children receiving vaccinations and children exhibiting the onset of developmental disorders, with Autism Spectrum Disorder (ASD) garnering the most public attention. With increasing numbers of parents delaying or forbidding their children from receiving vaccinations, along with the re-emergence of previously eradicated disease outbreaks and casualties, questions about the salience of Wakefield’s anti-vaccination statements arise. Investigation here is key …
