Hab Cyanobacteria In Northeastern Sc Retention Ponds: Time Trends In Abundance And Relationship To Water Quality, Kathryn I. Hanson

Honors Theses

The accumulation of polluted runoff in retention ponds can create water quality conditions that favor development of harmful algal blooms, including toxin-producing cyanobacteria. This can present a health risk to pedestrians and nearby residents, as many such ponds are surrounded by walkways or housing complexes. Blooms can also cause harm to natural ecosystems, periodically causing hypoxic conditions and toxin buildups. This study aims to form a more complete understanding of the population dynamics of certain potentially harmful phytoplankton genera, in relation to water quality parameters in retention ponds. Sampling was performed in five ponds chosen to reflect a variety of …

Validation Of A Passive Sampler For Tracking Harmful Algal Toxins In Natural Waters, Hailee Eiker

Honors Theses

Algal blooms that produce toxins that are harmful to the health of people, animals, and the environment are known as harmful algal blooms (HABs). Recently, rising global temperatures, nutrient pollution, and an increase in the frequency of extreme hydrologic events have made HABs a bigger problem. This has all led to greater cultural eutrophication which is a major contributor to the spread of HABs. Cyanobacteria make up the bulk of HABs in freshwater systems, microcystins being among the cyanotoxins that are most frequently reported and studied. Taking grab samples of water is the current standard procedure for sampling cyanotoxins, however, …

Effect Of Downregulating Lactate Dehydrogenase In Alzheimer’S Disease Using A Drosophila Model, Hannah Higgins

Honors Theses

According to the CDC, approximately 5.8 million Americans suffered from Alzheimer’s disease (AD) in 2020. AD is characterized by progressive memory loss and typically develops after the age of 60. There are many studies that suggest different causes of Alzheimer’s such as oxidative damage, amyloid plaque buildup, and metabolic dysfunction. Lactate Dehydrogenase (LDH) is an enzyme that is found in many tissues within the body and functions within cellular metabolism. The enzyme catalyzes the reversible reaction that converts lactate to pyruvate coupled with the reduction of NAD+ to NADH. Pyruvate is then used in the Krebs cycle to create ATP. …

Recent Snap Participation In Farmers Markets: Market Representatives’ Perspectives, Laura Fincher

An Examination Of Income Elasticity Of Demand For American Professional Sports, Michael Hansen

Honors Theses

This study examines the economic factors of demand that affect Americans’ desire to purchase tickets for professional sporting events. Most notably, it illustrates how changing household disposable income affects demand for the quality and quantity of attendance to NBA, NFL, and MLB games. Utilizing the total annual attendance of every U.S.-based professional team in these three leagues over a nine-year period, as well as the cost of tickets and other attendance-related expenses (e.g., concession prices), we obtain the total income elasticity of demand. This study then breaks down income elasticity of demand into both its quantity and quality components through …

Benefits Of A Community Reentry Intervention For Reentry Self-Efficacy In Homeless Shelter Residents With Past Incarceration, Kathryn E. Hurley

Honors Theses

The U.S. has one of the highest levels of incarceration and recidivism in the world (American Civil Liberties Union, 2022; U.S. Department of Justice, n.d). Several factors contribute to recidivism, including the loss of monetary funds and loss of housing upon incarceration. Homelessness especially predicts recidivism. It has been found to increase the risk of recidivism by almost 50% (Jacobs & Gottlieb, 2020). Within the context of a long-term ongoing participatory community action research Project in homeless shelters (Reeb et al., 2024), this study examined the benefit of reentry support sessions within the homeless shelter environment, with an attempt to …

Features Selection In Regression Models Using Variance-Based Sensitivity Analysis, Jakob Spiller

Honors Theses

Variance-based sensitivity analysis serves as a crucial tool for assessing the variability of inputs on the output of complex mathematical models. In this thesis, we study Sobol indices, a class of variance-based sensitivity analysis, to quantify the importance of each input variable on the overall variability of the model output. We initially discuss Sobol’s first and total order indices. This includes a brief demonstration through two examples: the Sobol G-function and a polynomial function each with six input variables. These examples serve to highlight the theoretical foundations and practical applications of Sobol’s indices in analyzing model sensitivities. Mainly, we apply …

Differences In Dynamic Knee Valgus Using Kinesiology Tape In Female Athletes, Riley J. Williams

Honors Theses

Excessive dynamic knee valgus (DKV) is commonly known as improper alignment in the frontal plane combined with excessive hip adduction, internal rotation, and tibia external rotation (Besier, Gold, Delp, Fredericson, & Beaupré, 2008; Maykut, Taylor-Haas, Paterno, DiCesare & Ford, 2015). More specifically, DKV is a medial collapse of the knee resulting in a hip adduction and internal rotation, tibial abduction and medial knee displacement, which increases the ACL strain (Llurda-Almuzara et al., 2020). Namata et al. (2018), using a three-dimensional kinematic analysis, reported female athletes are more commonly known to obtain a greater knee valgus angle when participating in landing …

Autoethnography For Professional Growth In Science And Social Studies Pedagogy, Grace E. White

Honors Theses

A large body of research shows that reading and math instruction receive significantly more time, attention, and instructional minutes than science and social studies instruction in elementary classrooms(VanFossen, 2005; Wilkens, 2009; Blank, 2013; Rosenshine, 2015). In this study, I use an autoethnographic reflective research framework to combat the challenges of science and social studies professional growth while student teaching at a rural texas elementary school that has chosen to require only math and reading instruction from their teachers. It was found that science and social studies is most easily incorporated through the existing reading and math curriculum. The autoethnographic process …

Listeria monocytogenes is a pathogen with the capability of causing severe illness in individuals who consume contaminated foods. Many foods have been found to harbor the bacterium, but dairy products, produce, and other prepackaged foods are particularly susceptible to contamination. Contaminated foods are exposed to a variety of environmental conditions during packaging, processing, consumption, and digestion, all of which play an essential role in modulating the survival and pathogenesis of L. monocytogenes. Conditions of particular interest include cold storage, presence of food additives, and activity of antimicrobial enzymes such as lysozyme. My honors thesis research has focused on elucidating how …

The Effects Of Fatigue On Landing Forces In Competitive Female Irish Dancers, Anna G. Robinson

Honors Theses

Lower extremity injuries are highly prevalent within the Irish dance population, yet research surrounding potential determinants is scarce. Many movements, particularly jumps, in Irish dance are constituted by a one-foot landing with the ankle in a plantarflexed position and the knee fully extended. This unique landing technique is contrary to other forms of dance, such as ballet, where landings typically allow for some knee flexion in a plie-like position. Subsequently, this aesthetic constraint requires large amounts of strength and balance, in addition to forcing the structures of the foot and ankle to absorb the entire shock of the landing. This …

Far From First Kill: Sapphic Fan Campaigns + The Fight For Queer Television, Lake Best

Honors Theses

Over the decades, LGBTQ+ media has had a long history of, despite getting better, more popular, more powerful each time, being canceled, delayed, even simply never seen again. This has led to justified anger, sorrow, + distress from the queer fandom communities, who, already inspired by the sense of activism that their community is founded on, have created over 8 years of online fan campaigning to fight back, maybe even bring the shows from the grave to a new life. This case study will examine 6 of those campaigns, ranging from the birth of modern queer fandom in We Deserve …

Relationship Exploration Through Music: Music Therapy Treatment Considerations For Adolescents With Attachment Trauma, Jaylee A. Sowders

Honors Theses

Interpersonal relationships are key to navigating our understanding of ourselves, others, and the world. However, our ability to form and maintain healthy relationships depends greatly on our experiences as children. Attachment theory suggests that our initial relationships and their characteristics can impact our sense of comfort and safety in later attachments (Bretherton, 1992). Challenges and trauma in attachment at a young age may hinder a child’s development into adulthood where interpersonal relationships are key to navigating our academic, professional, and personal environments. If left unaddressed, these challenges can become exacerbated in adolescence as teenagers form more concrete understandings of themselves …

Modeling The Opioid Crisis In Virginia: A Differential Equations Model Assessing The Impact Of Medication-Assisted Treatment On The Addicted Population, Maniha Zehra Akram

Honors Theses

The opioid epidemic is prevalent in countless communities throughout the United States and has yet to be mitigated. Treatments for OUD (opioid use disorder) include Medication-Assisted Treatment (MAT) and treatment without medication (non-MAT), with the former being judged as more effective in terms of lower relapse rates, death rates, and criminal activity (U.S. Food & Drug Administration, 2023; SAMHSA, 2024). Motivated by the promising research on MAT, this paper models the relationship

between the treatment and addicted populations using a system of ordinary differential equations. In addition to producing closed-form equilibrium solutions, the model leads to the conclusion that expanding …

Autopathography Across Media: Trauma And Fluid Embodied Subjectivity, He (Kristen) Shen

Honors Theses

Illness memoirs with first-person point of view have gained more attention in recent years among medical sociologists and anthropologists. Different from traditional “case histories”written by doctors that are in danger of ignoring patients’ voices, autopathograhical works delineate narrators’ transformative experiences of persons to patients, emphasizing the importance of gaining social understanding of illness. Focusing on three works within the category of autopathography across genres and media forms in the late 1950s and contemporary periods, The Cancer Journals (1980) written by Audre Lorde, The Collected Schizophrenias (2019) written by Esmé Weijun Wang, and The Diving Bell and the Butterfly (2007) directed …

A selenate respiring bacterium, Dechloromonas sp. A34, was isolated from a seleniferous mining site in southeastern Idaho. A34 was of interest due to its ability to respire up to 20 mM selenate, the highest concentration tested. The strain has been proposed to represent a new species of bacteria within the Dechloromonas genera, with the prospective name Dechloromonas selenatirespirans (manuscript in preparation). Our research presents characterization of a putative periplasmic binding protein found within an operon that contains genes encoding a putative selenate reductase. The gene, named serX (selenate reductase gene X), is 855 base pairs and encodes a putative …

Maine As Modernism’S Vernacular Muse: The Ogunquit Artists Colony As Microcosm For The Transition To American Modernism, Lydia C. Burke

Honors Theses

Maine has played a vital but largely unacknowledged role in the development of American modernism as both an environmental and cultural repository of inspiration. By examining the artistic and pedagogical tensions present in the Ogunquit, Maine art colony, this thesis explores Maine as an inspiration point for many of the foundational artists and teachers of the American modernist art movement. The gap in literature addressing the question, “why Maine?” leaves a void in the scholarship of American history and art history. Setting the scope of its research within this vital question, this thesis argues that Ogunquit, Maine served as a …
