Foraging arm preference was tested in two species of starfish: Asterias vulgaris and Luidia clathrata. No evidence was found for a species-wide preference or for a preference by individual sea stars, but trials were impacted by illness and resulting low sample size.
Effects Of Temperature On Enzyme Activity Of Aquatic Litter-Associated Fungi, Nicholas Bautz
Effects Of Temperature On Enzyme Activity Of Aquatic Litter-Associated Fungi, Nicholas Bautz
Honors Theses
The decomposition of leaf litter in aquatic ecosystems is carried out mostly by microorganisms, including bacteria and fungi. Fungi, known as aquatic hyphomycetes, dominate microbial communities in the decomposition of leaf litter. These fungi produce extracellular enzymes that aid in the sequestration of carbon and nutrients and lead to the breakdown of complex plant polymers. We evaluated the effects of temperature on extracellular enzyme activity within the framework of the Metabolic Theory of Ecology (MTE). The activity of β-1,4-glucosidase and β-1,4-xylosidase was estimated fluorometrically using artificial substrate analogs. Phenol oxidase activity was estimated spectrophotometrically from oxidation of L-DOPA (L-3,4-dihydroxyphenylalanine). We …

Through examining and exploring literature available on the topic, a need and argument for additional funding is constructed. Current partnerships are explored and methods of improvement, including an employee training course, are proposed. A new partnership with the …
Rain Gardens: The Return Of Ecosystem Services, Katie Dehaan
Rain Gardens: The Return Of Ecosystem Services, Katie Dehaan
Honors Theses
In the modern world impervious surfaces, especially in urban areas, abound. These include roads, highways, sidewalks, parking lots, and roofs that have replaced permeable surfaces, mainly open land, forests, and wetlands. Rainwater runs off of these surfaces collecting pollutants on its way to permeable areas. Rain gardens collect and process rainwater. Native plants with deep root systems process large volumes of rainwater and the microorganisms living in the soils and roots can process pollutants. The purpose of my research was to find out what variables affect species presence or absence in rain gardens. Species presence or absence at the time …
The Macroevolution Of Diadromous And Non-Diadromous Clupeiformes., Lindsey Dehaan
The Macroevolution Of Diadromous And Non-Diadromous Clupeiformes., Lindsey Dehaan
Honors Theses
Migration is a common life history strategy across the animal tree of life. This behavior is energetically demanding and may trigger strong selection for the evolution of an optimal ecomorphology to lessen energetic costs, yet the ecomorphology of migratory aquatic species remains poorly understood. Previous studies have demonstrated that migratory fishes exhibit predictable phenotypic patterns in body size evolution in response to evolving migration: migratory fishes are larger than non-migratory fishes. Migratory fishes may also have functional traits (e.g. fin shape) associated with locomotion that have experienced similar selective forces and exhibit predictable evolutionary patterns, resulting in migratory lineages sharing …
Is Natural Selection Shaping Florida Manatees? : An Investigation Into The Body Shapes Between The Subspecies Of The West Indian Manatee, Juliane Johnson
Is Natural Selection Shaping Florida Manatees? : An Investigation Into The Body Shapes Between The Subspecies Of The West Indian Manatee, Juliane Johnson
Honors Theses
The West Indian manatee (Trichechus manatus) is currently divided into two subspecies: the Antillean (T. m. manatus) and Florida manatee (T. m. latirostris). Florida manatees are found at the northern extreme of the species range, primarily inhabiting the waters around the Florida peninsula, while the Antillean manatee inhabits the remaining range from the Caribbean islands to eastern Brazil. Only in the range of the Florida manatee does water temperature drop below 20°C during the winter, and these manatees have to seek warm water refuge for thermal regulation. Allen's rule predicts that in colder climates animals will adapt to have smaller …
Oil Preference In Ants And Arthropod Diversity In Urban Environments, Itzel Guzman-Hernandez
Oil Preference In Ants And Arthropod Diversity In Urban Environments, Itzel Guzman-Hernandez
Honors Theses
The success of certain ant species in urban areas is largely unknown. Available food in the environment could affect the composition of ants in urban areas due to a possible relationship between ant physiology and diet. I tested the oil preference of ants as a function of available arthropod prey in urban environments. I hypothesized that as arthropod diversity decreased, ant abundance at oil baits would decrease. Oil is an important nutrient that can affect ant body functions and activities. Ant foraging activities have been found to be affected by lipid depletion. A food source where ants can obtain oil …

Relations Between Self-Regulation, Divergent Thinking, And Perceived Stress In Emerging Adults, Haven Wright
Honors Theses
This study investigated the relationships between self-regulation and stress, self-regulation and creativity, and perceived stress as a mediator for the relationship between self-regulation and creativity. Questionnaires were administered to undergraduate students to individually access each construct. Creativity was measured through divergent thinking and self-regulation was measured through the SRS and effortful control. Regression analyses were run to determine the relationships between the constructs. A negative association was found between effortful control and stress. Individual positive relationships were found between effortful control and all of the creative thinking styles except convergent-unpleasant. Lastly, the indirect effect of effortful control on the convergent-unpleasant …
Exploring Self-Determination And Recreational Sports Participation For Adolescents With Disabilities, Samantha K. Papp
Exploring Self-Determination And Recreational Sports Participation For Adolescents With Disabilities, Samantha K. Papp
Honors Theses
Self-determination is a vital skill for individuals with disabilities and provides significant benefits, such as more positive adult outcomes and greater quality of life. Recreational sports participation is another fundamental aspect of life for individuals with disabilities, as it leads to increased physical activity, enhanced self-esteem, and improved peer acceptance. Despite the well-researched benefits of both self-determination skills and recreational sports participation, a literature review revealed few studies that examined the relationship between self-determination and recreational sports participation for individuals, particularly adolescents, with disabilities. This mixed methods study was designed to fill this void, using questionnaires, interviews, and observations to …
Towards The Synthesis Of An Artificial Fluorescent Siderophore, Ashley Burns
Towards The Synthesis Of An Artificial Fluorescent Siderophore, Ashley Burns
Honors Theses
Siderophores are molecules capable of binding ferric ions with high affinity (Ka = 1052). This thesis outlines our attempts to synthesize an artificial siderophore, which incorporates a signaling group to help monitor the uptake of ferric ions. The artificial siderophore is a tripodal molecular receptor synthesized in a five-step procedure with a proposed final sixth step. Rhodamine 6G azide (95.0% yield) was formed from rhodamine 6G and the synthesis of 2-azidoethanamine was modified from the literature. The tripodal arm portion of the sensor was successfully synthesized by protecting the catechol of 2,3-dihydroxybenzaldehyde to form 3-formyl-1,2-phenylene dimethanesulfonate (98.8% yield). The reduction …

This thesis examined the current research on eating disorders and risk factors associated with their development. Through an online survey, information from freshman, sophomore, junior, senior, and graduate students at The University of Southern Mississippi regarding their current eating behaviors, feelings toward food and body, and demographic information was collected. Data collected indicated the student population’s level of …
In For A Shock?: Discretion And Disparity In Program Assignment, Brianna Mathis
In For A Shock?: Discretion And Disparity In Program Assignment, Brianna Mathis
Honors Theses
Due to the massive prison population in America, correctional agencies are considering alternatives to standard incarceration. These programs are designed to redirect individuals from serving a prison sentence, and are instead assigned to a program specifically targeted at reducing offenders’ likelihood at recidivating. Typically, the main focus of these programs centers on education, job training, and various types of counseling. The Mississippi Department of Corrections (MDOC) has implemented two programs that aim at reducing recidivism: the first was the Regimented Inmate Discipline Program (RID), which was later replaced with the Recidivism Reduction Program (RRP). While both programs were intended to …

This study investigates whether adult ESL programs in northern Mississippi are satisfactorily meeting those needs. Literature in the areas of second language acquisition, pedagogy, and adult ESL classroom research is reviewed, along with statistical background information relevant to the investigated geographic region. A qualitative methodological approach is employed, utilizing online, anonymous surveys to measure program characteristics and student …
Understanding Evolutionary Relationships Between Sedges Genus Rhynocospora, Abidell T. Thomas
Understanding Evolutionary Relationships Between Sedges Genus Rhynocospora, Abidell T. Thomas
Honors Theses
The relationships among species in the genus Rhyncospora, a member of the flowering plant family Cyperaceae, are of value to study as they are essential plant components to our ecosystem. Sedges are necessary for wetland preservation, land-sea barriers, and in many cases serve as a natural water detoxifier. Rhyncospora is a prime genus to ask questions about their phylogeny because their evolutionary history is poorly understood for them to be so prevalent. To understand the relationships between a specific group of sedges (genus Rhyncospora) I utilized nucleotide sequence data in a phylogenetic approach. Phylogenetics is the study of …

Searching For A Voice: An Introduction To Transgender Voice And Communication Therapy, Nicholas Brock
Searching For A Voice: An Introduction To Transgender Voice And Communication Therapy, Nicholas Brock
Honors Theses
Over the last 50 years, the cultural shift in the ideologies that shape the minds of individuals have primarily focused on social progressivism. Specifically regarding the United States, prominent leaders such as Harvey Milk pushed for social freedoms for members of the LGBTQ+ community. While Milk and his following fought for freedom and recognition, other leaders and supporters of the LGBTQ+ movement across the world were also fighting with fire in their hearts in their search for social justice. Barriers broke and glass ceilings shattered during these movements, but there is more to be done, today. As recognition of the …
The Impact Of Anti-Opioid Print Messages On High-Sensation-Seeking Personalities And Behaviors: A Comparative Study Of Public Service Announcements And Research, Allison B. Gordon
The Impact Of Anti-Opioid Print Messages On High-Sensation-Seeking Personalities And Behaviors: A Comparative Study Of Public Service Announcements And Research, Allison B. Gordon
Honors Theses
The rate of opioid overdose deaths has dramatically increased over the past several years. Efforts to reach users to describe the negative consequences of use appear to have little effect on users. This research seeks to understand how mass media messages, specifically printed public service announcements (PSAs), can reverse the upward trend of opioid use by targeting the attitudes and motivations of high-sensation-seekers. The hypothesis suggests a positive correlation between some advertisements and expressed intention to avoid trying or using opioids. Samples included students at Eastern Kentucky University in the Nursing, Psychology, and Sociology departments in addition to accredited, professional …

Research suggests that the social determinants of health should be evaluated in order to combat health disparities for disadvantaged populations. The five social determinants of health are economic stability, education, health and healthcare, neighborhood and built environment, and social and community context. Research has been done concerning built environment’s impact on health, however little research has been done on college student’s perception of their campus built environment and how it impacts their health. The purpose of this study is to determine if there is a relationship between negative perceptions of built environment and poor student health statuses, and if so …
The Influence Of The Law In American Literature And Culture, Emily Johnson, Steven Hamelman
The Influence Of The Law In American Literature And Culture, Emily Johnson, Steven Hamelman
Honors Theses
This piece explores the relationship between law and its influence within American literature and the overall culture. Themes of discrimination, corruption, greed, advocacy, and incriminating evidence, present in the analyzed texts and films, greatly plays into the American public’s perception of their judicial system. Is it truly the law influencing American literature and culture, or is it the sentiments of the masses influencing the legal field itself? This work aims at analyzing this question, while also making a point to explain what American citizens can do with such influence and knowledge.

Synthesizing Multifunctional Iron Oxide Nanodrugs And Developing A Model For Their Size Analysis Using Dynamic Light Scattering, Olivia George
Honors Theses
The growth of targeted drug delivery methods in modern cancer treatments has been the result of an increase in the quantity of drugs available, which is directly affected by the methods used in drug development. These drugs vary in size, shape, and mechanism of operation, so the characterizing techniques used must be adaptable to a variety of particle types. In this thesis, a variety of complex nanostructures were synthesized and characterized using dynamic light scattering (DLS), which is a rapid, non-destructive, and simply-operated size characterization method that does not introduce artifacts from sample preparation. The DLS data was then analyzed …
A Historical Analysis Of Non-Normative Embodiment Through The Lens Of Frankenstein’S Creature, Ashley H. Hobson
A Historical Analysis Of Non-Normative Embodiment Through The Lens Of Frankenstein’S Creature, Ashley H. Hobson
Honors Theses
A trend to historicize the field of Disability Studies has emerged in recent years. However, little research has been done to place different societies and generations in conversation with one another. This thesis will utilize various adaptations of Mary Shelley’s Frankenstein in order to explore shifting anxieties concerning non-normative embodiment through the vessel of the Creature. I examine the Creature’s changing physical form next to scientific and medical literature of the period to explore connotations of disability and otherness within that society. I consider the manifestation of anxieties towards non-normative embodiment through Mary Shelley’s 1831 Frankenstein, James Whale’s 1931 …
Academic Feminists Analyses Of Female Celebrities From The 1980s To Today, Brittany A. Carey
Academic Feminists Analyses Of Female Celebrities From The 1980s To Today, Brittany A. Carey
Honors Theses
This thesis examines the history of academic feminists and their changing debates over race, class, sexism, and sexual preference from the 1980s to the present. In the 1980s, white feminists tended to focus on sexism in the workplace and class discrimination, while black feminists focused instead on the racism and classism that black women faced both inside and outside of academia. More recently, millennial feminists, in both third- and fourth-wave feminism, have continued to focus on racial discrimination within feminism (and broader society) while also examining women’s sexual preferences. However, they have stopped focusing on sexism in the workplace and …
Women’S Resistance: Patient Pathographies And Medical Authority, Anna Claire Elliott
Women’S Resistance: Patient Pathographies And Medical Authority, Anna Claire Elliott
Honors Theses
In recent years, illness narratives have risen in popularity. Women’s medical narratives in particular have gained momentum in the literary world, and they often share commonalities including the inherent theme of medical resistance and an emphasis on the power dynamic between patients and physicians. This thesis will examine two pathographies, Susanna Kaysen’s Girl, Interrupted and Porochista Khakpour’s Sick, in the contexts of gender and disability studies, as well as theories of illness narratives. I examine how each text resists medical authority, and I also closely survey the physician-patient relationships within each text. The themes of gender and disability emerge …

The rock type, composition, structures, and fossils were identified at each site; unit thicknesses were measured, and stratigraphic relationships were analyzed for available exposures. Using GPS coordinates, each site was mapped on Google Earth Pro. The data collected at each site, aerial photographs, and topographic maps were used to identify each formation. The variability between previous works and this study was analyzed. The primary rock type found in the Tallahatta Formation is siliciclastic silty claystone and sandstone; some …
Microrna Identification And Target Prediction In The Whitefly (Bemisia Tabaci), Alexis Aleman
Microrna Identification And Target Prediction In The Whitefly (Bemisia Tabaci), Alexis Aleman
Honors Theses
RNA interference, referred to as RNAi, is a biological phenomenon whereby knock-down of gene expression can be achieved through the use of RNA molecules, including small interfering RNAs (siRNAs) and microRNAs (miRNAs). The use of miRNAs is an endogenous pathway that results in the degradation of the miRNA strand’s complementary messenger RNA (mRNA), preventing the translation of the mRNA and therefore the production of the proteins necessary for gene expression. While RNAi is a biological phenomenon that occurs naturally, it is also a method that can be used and manipulated in the laboratory to try to control the expression of …
Antibiotic Resistant Bacteria Isolated From Michigan Birds - A High School Learning Experience, Cody Benfant
Antibiotic Resistant Bacteria Isolated From Michigan Birds - A High School Learning Experience, Cody Benfant
Honors Theses
Bacteria, extremely small prokaryotic cells, are everywhere throughout the world. One striking thing about bacteria is their size: comparing a 2-micrometer bacterial cell to a 6-foot-tall human is similar in scale to comparing a 6-foot-tall human to the distance between Chicago, IL and Denver, CO! Despite their small size, bacteria are found in almost every ecosystem and environment imaginable. From deep sea hydrothermal vents to the clouds miles in the sky, there are trillions of bacteria flourishing in all of Earth’s ecosystems, performing many important functions in global nutrient cycles. While the majority of bacteria are beneficial to humans, …
