Comparison Of Suicidality Among Heterosexual And Sexual Minority Individuals, Ashley R. Pate

Honors Theses

Previous research suggests that sexual minority individuals have a higher risk of suicidal ideation and suicide attempts than do heterosexual individuals. Little research has been done to determine what may cause these differences and how living in a conservative region may contribute to it. This study sought to compare risk factors for suicidal ideation among heterosexual and sexual minority college students in southern Mississippi. To do so, suicidal ideation was examined, as well as thwarted belongingness (TB) and perceived burdensomeness (PB) – two robust predictors of suicidal ideation. It was hypothesized that sexual minorities would have elevated TB, PB, and …

I Love My Team! Factors Leading To Relationship Formation With A Sports Team, Carly L. Odom

Honors Theses

The sports industry is highly profitable, with a large and diverse fan base. Many people claim to be loyal to different teams, but what moves a more ‘casual fan’ to the team ‘fanatic’ status? Prior research in sports marketing focuses on elements such as geography and family history, while general marketing research considers the impact of behavioral and emotional loyalty (Chaudhuri and Holbrook, 2001). This focus on strict loyalty can, however, be limiting. Examining the factors within the larger relationship context gives us more insight into extreme fans (Pimentel & Reynolds, 2004), as well as the more casual fan. Prior …

Language Attitudes And The Learning Environment: The Effects Of Regional Dialect On Perceptions Of Teacher Credibility, Marissa C. Mcgillis

Honors Theses

The purpose of this study was to investigate how differences in regional dialect affect students’ perceptions of teacher credibility. In a broader sense, the research aimed to improve teacher-student interactions by identifying communication barriers created through cultural differences. 109 students at the University of Southern Mississippi who identified as natives to the American South participated in the study. 52 of the participants listened to a lecture given by a Standard American English speaker, and the other 57 participants listened to the same lecture delivered in American Southern English. Both groups completed a survey with twelve seven-point semantic differential scales, measuring …

An Analysis Of Visitor Safety In The Natchez Trace Parkway, Devin S. Mcgee

Honors Theses

The following study focuses on the safety of visitors travelling the Natchez Trace Parkway and their general safety while on Parkway property. The aim of the study was to conduct qualitative research in order to assess the hazards and risks that may befall the visitors of the Natchez Trace Parkway and how to combat these risks in the most direct way possible. A sample of recreational and law enforcement rangers took part in a questionnaire regarding their opinions of the level of safety at the park, and a diluted risk assessment was conducted while travelling through the section of the …

A Study Of Object Play In Captive Bottlenose Dolphins (Tursiops Truncatus), Victoria L. Johnson

Honors Theses

Behaviors related to play are positively reinforcing as they promote the continued exhibition of play behaviors in a variety of animal species. Play in animals is thought to contribute to the development and practice of skills animals require across their lifespan (i.e., foraging, mating, etc.). In bottlenose dolphins (Tursiops truncatus), several categories of play can be observed such as solitary play, social play, locomotor play, predatory play, and object play. The aim of the present study was to observe how variables of age-class, sex, object type, and play sociality influenced dolphin object play by utilizing video data from a …

Laterality Preferences Completing A Tool-Use Task In Asian Small-Clawed Otters (Aonyx Cinereus), Stephanie E. James

Honors Theses

Laterality is defined as the occurrence of each cerebral hemisphere having asymmetric control over the different sides of the body, leading to preferences to use one side of the body over the other for various behaviors. Many types of laterality exist, but handedness is the form that is most predominantly assessed. Handedness in animals is of special interest to laterality researchers, as humans were once thought to be the only species that exhibited lateralized hand preferences. The aim of the current study was to determine if Asian small-clawed otters exhibit significant paw preferences in behaviors associated with completing a tool-use …

Phylogenetic Relationships Of The Genera Of Achariaceae Based On Analyses Of Morphological And Dna Data, Corey L. Pagart

Honors Theses

Achariaceae are a mostly tropical family of flowering plants consisting of about 29 genera and 150 species of trees and shrubs. Although they are closely related to passionflowers (Passifloraceae), violets (Violaceae), and willows and cottonwoods (Salicaceae), phylogenetic relationships of the genera remain unclear because the only studies have been focused on particular genera or had limited sampling. Few studies of the family in general have been conducted, except for some on species that produce chaulmoogra oil, a commonly used historical treatment for leprosy. For my study, I investigated the relationships of the genera within the family using morphological and molecular …

An Analysis Of Dvořák’S Symphony No. 6, Ii, Using Neo-Riemannian Transformation Techniques, Mary Hannah Mallett

Honors Theses

Music theory is often used to analyze compositions and provide insight into the inner workings of the literature. Any new type of analysis provides a different view of the work and they can all be used to better understand the work, composer, and performance practice. This analysis uses Neo-Riemannian Transformation Theory to highlight some of the voice leading within Dvořák’s Sixth Symphony. The Sixth Symphony currently has never been analyzed using Neo-Riemannian Transformation Theory. The entire second movement was analyzed using a traditional harmonic analysis and then the author selected three excerpts, containing voice leading that could be classified using …

Effects Of Marsh Fragmentation And Patch Area On Fish And Nekton Assemblages In Mississippi, Jennifer R. Main

Honors Theses

Fragmentation divides continuous habitat into smaller patches. Fragmentation can also produce smaller populations of species, because fragmentation can split a population into smaller groups. Both terrestrial and aquatic ecosystems suffer from fragmentation. There are a variety of fishes that live along marsh, each depending upon the marsh for protection, food, and sometimes even competition. Species richness of fishes can be altered due to marsh fragmentation. I predict islands with a larger patch index should have a higher species richness of fishes. For this study, fish assemblages at 20 islands of marsh were sampled in the months of June and July …

Effects Of Temperature Gradient, Substrate Composition, And Canopy Cover On The Spatial Distribution Of Topminnow Species: Fundulus Notatus And Fundulus Olivaceus, Austin M. King

Honors Theses

Hybrid zones are locations where two interbreeding species coexist and hybridize. The spatial distribution of ecologically similar species is of primary interest in understanding the formation and stability of hybrid zones. These hybrid zones are of significance as they allow for insight into how speciation occurs naturally within the environment. A variety of factors may play a role in determining the spatial distributions of species within hybrid zones. Examples of these factors include variations in temperature gradients, substrate composition, and changes in canopy cover. Fundulus olivaceus and Fundulus notatus are generally found within upstream and downstream habitats respectfully. These habitats …

Understanding Narcissistic Personality Traits And Aggression: The Roles Of Self-Esteem And Gender, Regis S. Junearick

Honors Theses

The present study investigated the established relationship between narcissistic personality traits and aggression (e.g., Barnet & Powell, 2016; Baumeister et al., 2000; Bushman & Baumeister, 1998). Specifically, the study aimed to understand this relationship in a more nuanced fashion and proposed that 1) the relationship is indirect through self-esteem (mediation) and 2) the relationship is stronger in males than in females (moderation). Participants were 269 undergraduate students from the University of Southern Mississippi. A battery of self-report measures [Narcissistic Personality Inventory (NPI; Raskin & Terry, 1988), Pathological Narcissism Inventory (PNI; Pincus et al., 2009), Rosenberg Self-Esteem Scale (RSES; Rosenberg, 1965), …

Solving The Yang-Baxter Matrix Equation, Mallory O. Jennings

Honors Theses

The Yang-Baxter equation is one that has been widely used and studied in areas such as statistical mechanics, braid groups, knot theory, and quantum mechanics. While many sets of solutions have been found for this equation, it is still an open problem. In this project, I solve the Yang-Baxter matrix equation that is similar in format to the Yang-Baxter equation. I try to solve the corresponding Yang-Baxter matrix equation, ������=������, where X is an unknown ������ matrix, and ��=[0����0] or [0−��−��0], by using the Jordan canonical form to find infinitely many solutions.

Paleoecological Analysis Of The Clayton Formation (Paleocene) Near Malvern, Arkansas, Brenna J. Hart

Honors Theses

The Clayton Formation is a section of the Midway Group immediately above the Cretaceous-Paleogene boundary that contains marine fossils from the Paleocene Epoch. The formation is composed of glauconitic sand, clay, marl, and limestone. Fossils within the formation commonly occur in clay or are concentrated in conglomeratic lag lenses. To assess paleoecology of the region during the Paleocene, the Clayton Formation was sampled for fossil content at a distinctly visible exposure along Interstate 30 near Malvern, Arkansas, that was excavated as part of a landslide mitigation project. Complimentary sites were sampled nearby along the Ouachita River and behind a shopping …

African-American Perceptions Of Community-Oriented Policing Programs, Adrian L. Griggs

Honors Theses

Reports of police killings of unarmed African-American men have been commonly featured on the news in recent months. Protests in response to those incidents have occasionally turned into riots, and the tension between the minority community and police remains unchanged. There is always a racial variable implicit whenever the African-American community policing debate arises. Researchers have conducted studies on this challenge and have examined differences in perceptions of police officers between African Americans and other racial groups. Studies have been conducted that examine why there might be less satisfaction with police among African Americans but have not considered how these …

The Preparation Of Synthetic Myod Mrna For Cellular Differentiation And Innate Immune Response Downstream Application, James D. Grenn

Honors Theses

The development of therapeutic immune responses from the manipulation of embryonic stem cells (ESCs) via induction of synthetic RNA with 5’ capped and 3’ poly(A)tailed ends would lead to development of stem cell therapy. A necessary step in attaining such a goal is to first produce an mRNA transcript from a plasmid containing the open reading frame (ORF) for a transcription factor for cellular activation.

In this research, the DNA plasmid pMD4 encoding MyoD was transcribed into synthetic mRNA. The plasmid was first amplified using Polymerase Chain Reaction (PCR), and analyzed using gel electrophoresis. The amplified template was purified via …

Efficient Denoising And Sharpening Of Color Images Through Numerical Solution Of Nonlinear Diffusion Equations, Linh T. Duong

Honors Theses

The purpose of this project is to enhance color images through denoising and sharpening, two important branches of image processing, by mathematically modeling the images. Modifications are made to two existing nonlinear diffusion image processing models to adapt them to color images. This is done by treating the red, green, and blue (RGB) channels of color images independently, contrary to the conventional idea that the channels should not be treated independently. A new numerical method is needed to solve our models for high resolution images since current methods are impractical. To produce an efficient method, the solution is represented as …

Religious Commitment, Job Satisfaction, And Social Acceptability Among Religious Groups, Kathryn E. Dozier

Honors Theses

This study seeks to develop a better understanding of the relationships between religious commitment, social support, and job satisfaction. This research specifically investigated the correlations between religious commitment and social support, religious commitment and job satisfaction, and social support and job satisfaction. After surveying undergraduate students from a southern university, there was no statistical evidence supporting the idea that the indicated combinations contributed to job satisfaction. The research did demonstrate, however, a correlation between religious commitment and social support. In addition, groups were tested for significant differences in levels of religious commitment, social support, and job satisfaction; the groups based …

Altering The Structure Of Carboxysomal Carbonic Anhydrase Csosca To Determine The Necessity Of The N-Terminal Domain In Csosca Function, Dana L. Dillistone

Honors Theses

In this project, a DNA construct was designed and developed to remove the first fifty amino acids of the CsoSCA protein in the chemolithotrophic bacterium Halothiobacillus neapolitanus. The csoS3 gene codes for a carbonic anhydrase enzyme (CsoSCA) that is unique to a structure called a carboxysome. Carboxysomes are polyhedral microcompartments where carbon fixation is housed. The carbonic anhydrase is a shell-associated protein that improves the catalytic efficiency of ribulose-bisphosphate carboxylase/oxygenase (RuBisCO), the enzyme that catalyzes the fixation of carbon. By deleting the first fifty amino acids of the carbonic anhydrase, the necessity of the amino acids in carboxysome function was …

Phylogenetic Relationships Of Salicaceae Based On Analyses Of Nuclear Dna Data, John Marshall Diffey

Honors Theses

Salicaceae are an economically and ecologically important family of flowering plants. The family includes willows and cottonwoods and was recently enlarged to include a large number of tropical species formerly placed in the family Flacourtiaceae. Relationships of these tropical relatives to willows and cottonwoods have been explored at a basic level using morphology and plastid DNA data, but to date no molecular phylogenies have been constructed with significant sampling of nuclear DNA, which sometimes results in a different picture of relationships because of its biparental inheritance. For this project, I sampled one region of nuclear DNA (GBSSI) across the family …

Jealousy And Romantic Relational Aggression Among Dating College Students, Ashlee A. Bryant

Honors Theses

Most of the research on relational aggression has been conducted with samples of older children and early adolescents and has focused primarily on same-sex peer relationships (Goldstein & Tisak, 2004). The aim of this study was to contribute to the relatively meager research on relational aggression in the context of college students’ romantic relationships by exploring the role of interpersonal jealousy. Participants included 377 undergraduate student volunteers (64 men and 313 women) ranging in age from 18 to 58 who were recruited through the Department of Psychology’s subject pool (i.e., Sona). The data were collected in the form of an …

How Parenting Style Relates To Adolescent Substance Abuse In An At-Risk Male Population, Bailee R. Brewer

Honors Theses

Parents have an important role in their children’s development. There is evidence that parenting behaviors such as parental involvement, monitoring of children, and inconsistent discipline play a role in adolescent substance use. The purpose of this study is to document perceptions of parenting behaviors among youth at a residential boot camp facility for at-risk adolescents, and to relate those perceptions to youths’ self-reported history of substance use. This study adds to previous research on parenting behavior by examining the parenting behaviors reported by troubled youth, rather than the more typically studied normative youth. Additionally, this study tests whether previously reported …

“Patriotism Is Not Enough”: Edith Cavell’S Life And Death In Anglo-American Context, Erin B. Blackledge

Honors Theses

In October 1915, British nurse Edith Cavell was killed by the Germans for aiding in the illegal liberation of Allied soldiers. In the wake of her death, the British government created a propaganda firestorm to garner both domestic and foreign support for the war. In particular, the propaganda featuring Cavell was highly gendered and over the course of multiple generations has generated a diverse, and often polarized series of social and political responses in both Britain and the United States. Through the examination of government documents, newspapers, and popular culture, such as film and children’s novels, this thesis examines the …

Recombinant Expression And Purification Of Amyloid-Β In E. Coli, Wisam M. Beauti

Honors Theses

Alzheimer’s disease (AD) is a common neurodegenerative disorder that affects people older than 65 years 1,2,5. It is characterized by the presence of extracellular plaque deposits that are seen specifically in the brains of AD patients 4,5. These plaques are mainly comprised of amyloid-β (Aβ) peptide aggregates. Aβ plaque production and deposition is believed to drive AD pathogenesis. Studying these proteins is crucial to understanding aspects of AD in order to develop possible therapeutic treatments. Recombinant expression of Aβ can also provide a handle to introduce mutations in the protein to further study their structure-function relationships. However, synthetic Aβ monomer …

The Effects Of Including Physical Activity In Classrooms With Children With Language Disorders, Shelby E. Auer

Honors Theses

As obesity becomes a rising concern in the United States and the importance of high test scores continues to add stress to students, physical activity opportunities are beginning to become less frequent in schools. The Center for Disease Control reports a total of 12.7 million children were classified as obese from 2011 to 2012 (CDC, 2015). While many researchers have also acknowledged this trend, the majority of studies focus on the correlation of physical activity in the classroom with increases in fitness and cognitive functioning levels among average population students, much like the research done by Webster, Russ, Vazou, Goh, …

Metagames: Postmodern Narrative And Agency In The Video Games Of Davey Wreden, Richard J. Andrews

Honors Theses

This study aims to determine how contemporary video games utilize self-reflexive narrative techniques to explore the strengths and weaknesses of video games as an artistic narrative medium. This study combines emergent digital game theory with established literary theory about self-reflexive narrative (also known as ‘metafiction.’) This synthesis is further informed by observing first hand player interaction with self-reflexive gaming platforms. A focus on the problems of ontology and epistemology for both gamers and readers allows comparison between treatments of these problems in both digital game theory and metafictional studies. My study compares these concepts and applies them to the operations …

Curating Curiosity: The Evolution Of Museological Theory In The Late Seventeenth Century At The Bibliothèque De Sainte-Geneviève, Erin L. Anderson

Honors Theses

The evolution of museological theory at the Bibliotheque de Sainte-Genevieve marks a transition in the history of collecting during the early modern period. Although the contents of the collection remained largely unchanged from earlier Wunderkammern, the acquisition, display, and organization of artifacts within the cabinet had evolved tremendously by the end of the 17th century and one can begin to see the collection as a predecessor of modern museological methodologies.

During the competition, a short survey will be offered to contestants and leaders to obtain accurate and anonymous feedback regarding the contest and the impact of this event on the regional 4-H members who participate. Specifically, the survey will focus on how the SIUC hosted Hippology and Horse Bowl contest prepares 4-H members for further competitions and if the contest encourages students to pursue an agricultural field, particularly at SIUC. During the organization of the event, number of …

Evolution Of Eusociality In Ants Hymenoptera: Formicidae, Michael S. Holm

Honors Theses

Eusociality can be seen in a variety of insect families, including the ants (Formicidae). There is no clear understanding on how it evolved but it is well understood that transitions between social phases must happen. Several theories and hypothesis have been presented but none of them completely encapsulate the whole evolution of eusociality. Several studies on ants focus on different aspects of their evolution in the eusocial context and provide good supporting data. Two major models, Alternate Inclusive Fitness Model and Worker Behavior Model, are good blueprints for future research. As more data is collected and studies were done, more …
