Predictive Ability Of A 3d Body Scanning Mobile Application For Metabolic Health Risk, Caleb Brandner

Master's Theses

There is an increasing prevalence of obesity within the US and rising rates of metabolic syndrome among those aged 20-39 concurrent with a decrease in the reception of primary care. Limitations to healthcare including access, cost, and availability, highlighting the need for simple, efficient, and accessible cardiometabolic health risk screening. Given the surge in smartphone ownership over the last decade, this study sought to determine the predictive ability of a mobile 3D-optical (3DO) body composition assessment application in determining metabolic health risk. A total of 62 participants (female: 36) underwent traditional anthropometric measurements, 3DO body scanning using a smartphone application, …

Social Anxiety And Relational Aggression In The Peer Relationships Of College Women, Summer Boggs

Master's Theses

Relational aggression (i.e., a type of aggression in which the aggressor harms others by damaging their relationships, reputation, and/or feelings of social acceptance) is common among emerging adults and has been linked to several adverse correlates. Research on relational aggression among college students has found some evidence that it is positively associated with social anxiety; however, the specific components of social anxiety and the possible mechanisms through which this relationship may operate are unclear. The current study examined the relationship between social anxiety and relational aggression among college women (N = 292), focusing on fear of negative evaluation (FNE) …

Beyond The Clinic: Modified Internet-Delivered Parent-Child Interaction Therapy, Terreca Cato

Children who attend Head Start children are at increased risk for emotional and behavioral disorders. A variety of systemic factors contribute to their increased risk for problematic developmental outcomes. Parent-Child Interaction Therapy (PCIT) is an evidence-based intervention for improving positive parenting skills and children’s outcomes. This study included a multiple baseline design across participants and tested the effects of Internet-Delivered Parent-Child Interaction Therapy (I-PCIT) on improving Head Start mothers’ use of the Effective Commands that are part of the Parent Directed Interaction component of PCIT. Seven total mothers were recruited to participate in this study. Four mothers did not complete …

Estimation Of Mortality Rates For The Gulf Menhaden Stock And Reference Point Implementation For The Fishery, Catherine Wilhelm

Master's Theses

The Gulf menhaden stock is the target of a large commercial fishery in the Gulf of Mexico. To address the needs of both the stock and fishery, I performed two studies. I first addressed the natural mortality rates currently used in the Gulf menhaden stock assessment. To update these rates, I used data from a tagging study conducted from 1970 to 1988. Adult and juvenile menhaden were tagged, released, and recovered in fish processing plants. To evaluate the data, I built a Bayesian model using the negative binomial distribution to estimate natural mortality, catchability, and the overdispersion factor parameters. I …

Understanding The Impacts Of Topobathymetric Data On Storm Surge Model Predictions, Sydni Crain

Master's Theses

The topobathymetric characteristics of a region are regularly altered by natural and anthropogenic causes. This directly impacts the resulting storm surge during a hurricane. The primary goal of this research was to gain a better understanding of the impact that topography and bathymetry have on storm surge models, particularly the Advanced Circulation (ADCIRC) Model. Hurricane Zeta (2020) and Hurricane Ida (2021) were chosen as case studies; therefore, the Gulf of Mexico (GOM) was chosen as the study site. This research was completed by comparing ADCIRC storm surge results which were based on older, lower-resolution data with results derived from more …

Effects Of Increased Shoe Collar Height And Limb Dominance On Landing Knee Biomechanics In Collegiate Volleyball Players, Lindsey Legg

Master's Theses

Athletic footwear with higher collar heights are worn to restrict ankle motion. Reduced ankle dorsiflexion has been associated with increased frontal plane knee motion. Volleyball players wear mid-cut shoes (MC) that have an increased collar height rising slightly superior to the talocrural joint and malleoli. The purpose of this study was to determine the effect of MC and limb dominance on knee landing mechanics. It was hypothesized that participants would land with greater initial contact (IC) and peak frontal joint plane angles and moments and smaller IC and peak sagittal plane joint angles and moments at the knee in MC …

Caregiver Augmentative And Alternative Communication (Aac) Education And Training: A Survey Of Caregiver And Slp Perspectives, Michelle Hasenkampf

Master's Theses

Speech-language pathologists (SLPs) must address caregiver education and training throughout early intervention, including when implementing augmentative and alternative communication (AAC). Previous research has made recommendations describing practices for SLPs in this area, such as incorporating direct instruction and caregiver participation, as well as addressed how recommendations compare to implementation of these strategies in actual practice. Two parallel surveys were created to examine SLP and caregiver experiences and opinions of various topics and methods utilized in AAC caregiver education and training. 19 SLPs and 5 caregivers completed the surveys. SLPs notably exhibited differences in practice and opinions related to the methods …

Freckled Darter (Percina Lenticula) And Other Fishes’ Usage Of Wood Pile Habitat, Noah Daun

Master's Theses

Effectively sampling habitat with the proper techniques is essential for our understanding of the animals that use the habitat, both for individual species and entire species assemblages. Percina lenticula is a species of special concern in the state of Mississippi due to low numbers of historical records. This species is known to inhabit wood pile habitat in rivers, a habitat that has been under-sampled historically due to inefficiency with most commonly used gear. Seines are typically not effective at sampling wood piles, resulting in sampling bias underestimating the number of P. lenticula and potentially other species utilizing such habitats. This …

Driving Demands Of A Successful Protest: A Comparative Analysis Of Drivers That Leads To A Successful Outcome Of Protest, Prince Tetteh

Master's Theses

The 2020 Global Peace Index found that there has been a drastic increase of civil unrest incidents worldwide since 2011. According to the Index, there were 282% more riot cases and 821% more general strikes across the world, with Europe having the most riots, protests, and strikes. Extant literature suggests that protest is a web of interconnected demands that sends a weak signal to policymakers or the intended target. I examine some of the drivers of protest that are likely to impact the chances of protesters demands being met either in part or in full. I further analyze how each …

Determining The Refractive Index Of Phytoplankton Via Direct Measurement Of Cellular Structures, Michael Kamowski

Master's Theses

The refractive index of phytoplankton has never been directly measured before despite its importance towards studying the optical characteristics of marine particles. Previous attempts to measure it have been done through indirect methods. While these methods have proven useful, they contain assumptions about the particles morphology and composition that cause for uncertainty with the measurements. Through the use of the 3D Cell Explorer, a high precision holotomographic microscope, the RI of phytoplankton can be directly measured for the first time. With volume measurements, the phytoplankton were found to not display a single bulk RI, instead the bulk RI was different …

Comparative Analysis Of Rhizosphere And Endosphere Microbiome Of Different Blueberry Species (Vaccinium Sp.), Niladri Bhowmik

Master's Theses

Blueberries are an important agricultural commodity in all over the United States. Due to its health benefits, there is a huge demand globally, thus expanding the industry. Breeding programs are essential to maintain such industries. Challenges that play a role in contemporary breeding programs are various biotic and abiotic stress factors. Studies have shown that microorganisms are recruited by plants to alleviate them during stressful conditions. Though blueberries have been cultivated for about 100 years, how the microbiome has been affected due to this is poorly understood. We hypothesized that interspecific crosses and artificial selection have significantly changed the microbiome …

Predicting Suicide Risk Among Youths Using Machine Learning Methods, Saswati Bhattacharjee

Master's Theses

Suicide is the second leading cause of death among youths in the USA. Although machine learning approaches have provided great potential for predicting suicide risk using survey data, prediction accuracy may not meet the need for clinical diagnosis due to the intrinsic characteristics of datasets. In this study, I perform a comparative study of six classification algorithms including naïve Bayes (NB), logistic regression (LR), multilayer perceptron (MLP), AdaBoost (Ada), random forest (RF), and bagging using YRBSS dataset and investigate the effectiveness of several data handling techniques to improve the overall performance of suicide risk prediction.

The dataset consists of 76 …

New Insights Into The Paleovegetation Of The Ancient Underwater Forest Located In The Northern Gulf Of Mexico, Karla Lizarraga Garcia

Master's Theses

A well-preserved remnant of an ancient bald cypress forest (hereafter, Underwater Forest) constitutes the only known archive of a glacial refuge on the once exposed continental shelf of the Northern Gulf of Mexico. This forest existed around 41-72 yBP (MIS 3-5) according to the existing dating methods applied on previous studies. As the climate conditions and sea levels changed, the vegetation of this glacial refuge shifted from bald cypress forests to open marshes, altering the vegetation dynamics. The present research analyzed four new cores (21DF-5A, 21DF-5B, 15DF-6, and 16DF-3A), which provided additional insights into the vegetation that once existed in …

Introspective Accuracy For Social Cognition Across The Psychosis Spectrum: Influence Of Sleep Disturbance, Cassi Springfield

Master's Theses

People with schizophrenia-spectrum and bipolar disorders can have impairments in introspective accuracy (IA; ability to accurately estimate one’s own abilities). Research suggests that positive, negative, and depressive symptoms may be related to IA, but findings are mixed. Examining sleep disturbance as a determinant of IA may help explain these mixed findings. The current study aimed to explore the relationships between sleep disturbance, symptoms, and IA in participants across the psychosis spectrum. Participants completed diagnostic, symptom, and sleep disturbance assessments. Participants also completed social cognitive tasks, estimated their performance on the tasks (used to calculate IA), and indicated their confidence in …

Hydrothermal Fluid Transport Pathways Along Fractures And Veins At Brothers Volcano, Southern Kermadec Arc, Robert Atnip

Master's Theses

Hydrothermal fluid flow in fractures and veins is a key component in the mineralization of economic metals within calderas. But there are several methods by which fractures can form. Regional extension, episodic caldera collapse, and fluid overpressure all have the potential to create brittle features. Current studies focus on the formation of fractures and veins by these methods, but do not focus on the preferred movement of hydrothermal fluids through brittle features, nor which features are more dominant in active hydrothermal systems. This thesis introduces multiple studies to better understand which method of fracture creation dominates Brothers volcano. Data from …

Brazilian Camming: The Monetization Of Intimacy In Online Sex Work, Fernanda Veiverberg

Master's Theses

This thesis addresses a form of online feminized labor in Brazil, which employs digital technology to relieve the urges for intimacy and monetary insecurity. Camming is a genre of online sex work, in which cam models sell their body image and attention online through computer-mediated interactions. It constitutes a profitable activity that employs body performance without physical contact between model and client, typical in most categories of sex work such as prostitution, and where the clients are not mere spectators as within the pornography industry because camming requires authenticity and communication. For that, I explored three conceptual spheres that combined …

The Role Of Emotion Regulation And Alexithymia In The Relationship Between Sleep And Social Functioning, Lillian A. Hammer

Master's Theses

Poor sleep quality has been tied to worse social functioning outcomes, including greater loneliness, fewer social interactions, and lower social integration. While the relationship between sleep quality and social functioning has been investigated, other factors likely play a role in this complex relationship. Specifically, alexithymia and the use of different emotion regulation strategies may serve as moderators in the relationship between sleep and social functioning. Alexithymia and emotion regulation strategies are both related to sleep quality and social functioning. Yet, the impact of these emotional processes on the relationship between sleep and social functioning remains unexplored. Data for this study …

Gender Differences In Personality Dysfunction And Aggression In A Sample Of At-Risk Youth, Chloe O'Dell

Master's Theses

Youth with antisocial and borderline traits in adolescence have been found more likely to commit violence and experience negative outcomes later in life. There is evidence for gender differences in the manifestations of dysfunctional personality features (antisocial and borderline traits) and functions of aggression, but little research has sought to assess unique gender differences that may help unravel the sequelae of personality dysfunction in youth. Accordingly, this exploratory study examines gender differences in associations between antisocial features, borderline features, and proactive and reactive functions of aggression in a sample of at-risk youth. Four hundred and sixty-four adolescents (M_age = …

The Influence Of Range Shifts And Wind Energy On The Atlantic Surfclam (Spisula Solidissima) And Ocean Quahog (Arctica Islandica) Fisheries On The U.S. Outer Continental Shelf, Stephanie Stromp

Master's Theses

The Atlantic surfclam, Spisula solidissima, is a biomass dominant bivalve of the Northwestern Atlantic. The surfclam’s historic range extended from Cape Hatteras to Georges Bank, but recent decades of warming bottom water temperatures have caused the surfclam to shift its range to cooler waters north and offshore within the range of the ocean quahog, Arctica islandica. An ecotone now exists over much of the offshore range of the surfclam in which surfclams and ocean quahogs co-occur. Regulations prohibit fishers from landing both species in the same catch, limiting fishing to locations where the target species can be sorted …

The Relations Between Rumination, Thought Control, And Suicidal Thinking, Morgan Buerke

Master's Theses

Despite the far-reaching impact of suicide on our communities, we need more research to understand how suicidal thoughts develop, and what leads to their maintenance. As suggested by the depression distress-amplification model (Capron et al., 2013), emotion-regulation strategies such as rumination may cause or worsen suicidal ideation by amplifying the distress associated with negative thoughts. In addition, ruminative thoughts are often described as difficult to control, which may lead people to think about suicide as an escape from these uncontrollable thoughts. The current study examined the relationship between certain forms of rumination (i.e., brooding, reflection, anger rumination, and suicidal rumination) …

Benthic Habitat Mapping Of Mountain Top Bank Within The Northern Gulf Of Mexico Through Integrated Geophysical And Visual Data Analysis, Bethany Pertain

Master's Theses

Mesophotic coral ecosystems (MCEs) are among the seafloor ecosystems that have been poorly studied throughout the world’s oceans, but they are a vital and diverse ecosystem that should be prioritized for future mapping and ecological studies. Priority should be given to them because they possess natural, social, and economic values, and face a variety of threats, all of which, if not better understood will result in the loss of this unique ecosystem. Insights into these ecosystems, among other deep-sea environments, are lacking due to difficulty accessing them, inherent lag between data collection by an autonomous system and observation by a …

Beginnings Of The Nuevo South: Mexican Migration In 1970s And 1980s Mississippi, Isabel Loya

Master's Theses

Mexicans and Mexican Americans have been present in Mississippi since the early twentieth century with a large increase in the 1970s. The majority of the scholarship surrounding Mexican migration focuses on the 1990s leaving a historiographical gap concerning this earlier period of significant population growth. This thesis argues that Mexican migrants during the 1970s and 1980s were uniquely affected by Mississippi’s racial climate due to their ambiguous status in a Black and white society, where they fit in neither category. The examination of tactics by businesses, like B.C. Rogers Poultry plant, show the impact recruitment had on migrants’ living conditions …

The Implications Of Sexual Assault Awareness On Sexual Overperception Bias, Zach Buckner

Master's Theses

Heterogeneity has recently emerged in research investigating men’s overperceptions of women’s sexual receptivity, namely that such overperceptions are less robust than previously considered. Various social movements (e.g., #MeToo) could be a modern-day contextual factor that has reduced men’s tendency toward overperception. In this study, participants viewed hypothetical information regarding sexual assault perpetration committed by men or women (or control information) before rating opposite-sex targets on perceived sexual interest in them and reporting individual differences in just and dangerous world. The results indicate that individuals who hold stronger beliefs in an unjust world are more sensitive to perceived threats from potential …

I Was Looking For God: A Study Of Wehrmacht Personnel And Their Personal Relationships With Religion, Christopher Bishop

Master's Theses

The Wehrmacht was Germany’s fighting force in the field during World War II. Its brutality and discriminatory practices rivaled that of the Nazi paramilitary and police units dispatched alongside them in newly conquered areas during this conflict. Coming from a society that was not at all unfamiliar with Christianity, some within the Wehrmacht related to Christianity in some form and attempted to use it to either justify actions or make sense of the world around them.

While considerable scholarship exists on the Nazi Party’s relationship to Christianity as a convenient propaganda tool for both soldier and civilian alike, the historiography …

The King And His Court: The Culture Of Royal Power And The Creation Of The Angevin Empire Under Henry Ii, Joseph Jarrell

Master's Theses

Legal codes, literature, history, and violence were necessary aspects of royal power that in conjunction with resources gained from familial inheritance and a fortunate marriage allowed King Henry II to build, govern, and legitimize his rule over the Angevin Empire, as well as attempt to create an Angevin dynasty. Examining these subjects advances ideas about medieval royal culture and its relation to political power and legal power in the twelfth century Angevin Empire.

Historiography has long examined this period as the histories of great men, but recent trends have examined the interplay of power, politics, and gender during the Middle …

Disability Identity In Samuel Taylor Coleridge's Letters, Jackson Fields

Master's Theses

This thesis focuses on letters written by British Romantic author Samuel Taylor Coleridge, who wrote about his chronic illness during the period of emerging modern ideas of disability. Coleridge’s letters are valuable to readers in the twenty-first century because they enable us to track the formation and negotiation of Coleridge’s disability identity. As one of the most important thinkers and authors in the English language, Coleridge has a lot to teach us about how one can understand their illnesses, medical authority, and the influences of disability on friendships and social roles. This thesis considers Coleridge’s letters to his loved ones …

Hide And Seek: An Exploration Of Antipredator And Predator Avoidance Mechanisms In Orthopodomyia Signifera In Response To Predation From Toxorhynchites Rutilus, Nathaniel Dahlberg

Master's Theses

There have been many observations of larval Orthopodomyia signifera coexisting with the predator Toxorhynchites rutilus. There are three hypotheses that could explain how Or. signifera resists predation from Tx. rutilus. The first hypothesis states that larvae adapt behavioral changes that limit predation. The second hypothesis states thoracic setae serve as a physical defense that prevents Tx. rutilus from grasping Or. signifera. The third hypothesis states Or. signifera possess a chemical defense indicated by aposematic coloration. To test the first hypothesis larval Or. signifera were exposed to conspecific and heterospecific predation cues and their behavior was observed. Both cues …

The Influence Of Spatialheterogeneity On Ocean Quahog (Arctica Islandica) Population Dynamics Along The Mid-Atlantic Bight, Jillian Sower

Master's Theses

The ocean quahog (Arctica islandica) support an economically important fishery in the US, though little is known about their life history traits. To determine how these traits vary geographically, the age frequencies and growth rates from two New Jersey sites (NJ1 & NJ2) as well as Georges Bank (GB) and Long Island (LI) were analyzed. Though sexual dimorphism in bivalves is rare, recent research has shown that A. islandica display distinct differences in sizes between males and females, with females reaching larger sizes than those of males. To determine when this difference in size occurs, the growth rates …

Finding Balance: A Content Analysis Of How Newspaper Authors Framed Simone Biles Before, During, And After The 2020 Olympic Games, Hadley Howell

Master's Theses

Simone Biles was considered the GOAT, Greatest of All Time, going into the 2020 Olympic Games. However, after the COVID-19 pandemic, the Larry Nassar trial, and the weight of the world on her shoulders, Biles would withdraw from the women’s gymnastics team final competition for mental health reasons. Thus, the following study examines how Biles was framed in the ten most circulated newspapers in the United States before, during, and after the 2020 Olympic Games. Results show that an author’s race and gender, topic of the article, type of article, and if an article contained an image or not ultimately …

Impacts Of The Poultry Industry In Mississippi, Sara Watts

Master's Theses

This thesis examines the impacts of the poultry industry in seven counties in the Piney Woods region of South Mississippi: Wayne, Jones, Forrest, Lamar, Jefferson Davis, Marion, and Pike. Current research indicates that the poultry industry has a significant impact on the cultures and economies of rural towns throughout the United States. There is no current research that examines the effects of the poultry industry on residents of the Piney Woods. This thesis addresses that gap in the research and contributes to current understanding of how the industry molds and impacts the lives of those intimately associated with it.

I …
