This thesis updates and expands on Johnson and Schwadel’s 2019 study by applying a two-level hierarchical linear model to General Social Survey data updated to include data from 2015-2022, capturing how political affiliation, education, race, and economic context interact with broader political and economic contexts to shape environmental attitudes over time.
The results show that political affiliation remains the strongest and most reactive predictor of environmental spending attitudes. Republican respondents are significantly more likely to oppose environmental spending, especially under …

Genomic Epidemiology Of Staphylococcus Aureus Sequence-Type 72, Sachitaa Senthilkumar

Honors Undergraduate Theses

Staphylococcus aureus (S. aureus, SA) is a gram-positive bacterial colonizer and pathogen commonly carried on the skin and in the anterior nares of humans. SA colonization may lead to a variety of non-invasive (e.g., skin and soft tissue infections, SSTIs) and invasive (e.g., bacteremia and osteomyelitis) infections. The SA population is comprised of multiple lineages that can be delineated through multi-locus sequence typing (MLST), which compares nucleotide sequences within seven housekeeping genes. Strains belonging to an MLST share a common evolutionary history and phenotypic characteristics like antibiotic resistance or virulence. As a result, the epidemiology of lineages can be …

High-Throughput Drug Screening For Disease-Modifying Arthritis Therapy, Janapriya Vijayakumar

Honors Undergraduate Theses

Current therapy for arthritis predominantly focuses on the symptoms rather than the underlying causes of disease progression. Thus, it is necessary to identify novel drugs which target the underlying molecular basis of such diseases. Using high-throughput cell-based drug screening, we screened 458 different compounds, narrowed down from 811 starting compounds from the NIH Mechanistic Set. We selected drugs from the Mechanistic Set following Lipinski's Rule of 5 to ensure optimal pharmacokinetic properties. The study used modified primary human chondrocytes (IIAM-PRG4Luc), which secrete a lubricin promoter-driven luciferase reporter. We use this luciferase expression as a proxy to measure lubricin, a compound …

Investigation Of Lubricin-Stimulating Fda-Approved Compounds For A Disease-Modifying Osteoarthritic Drug, Swathi S. Menon

passively listening, impact emotional regulation following exposure to a stressor. The goal was

to better understand whether active participation in music offers greater emotional benefits

compared to simply listening, as previous research often highlights music’s role in emotional

modulation but overlooks the influence of performance-based engagement. A total of 28

participants either played music or listened to music and then completed both pre- and post-

stressor measures assessing mood, mental task load, and heart rate. Contrary to the original

hypothesis, findings revealed that participants from the listening group …

Development Of A Proposed Selective Medium For The Isolation And Differentiation Of P. Sordellii, Dimyana Bottros

Honors Undergraduate Theses

Clostridium, a genus of anaerobic, spore-forming bacteria, includes clinically and ecologically significant species like Clostridium difficile and Paeniclostridium sordellii. C. difficile causes antibiotic-associated colitis, while P. sordellii is linked to fatal infections and spontaneous abortions. Recent studies found both species in marine sediments, suggesting their role in environmental and wildlife health disturbances, including the 2013 mass mortality of over 300 manatees in the Indian River Lagoon. However, isolating and differentiating P. sordellii is challenging due to the lack of selective media optimized for its growth. This thesis proposes a novel selective medium tailored to P. sordellii’s physiological …

Environmental Law And Social Mistrust- How The Repeal Of The Chevron Doctrine May Hinder The Epa And More, Rebecca R. Collins

Honors Undergraduate Theses

I am specifically studying the effects of a recent Supreme Court decision will have on administrative law and specifically on the EPA. Simply put, the decision is likely going to foster distrust within the EPA and decisions that are made within environmental law, as the shift goes away from scientific experts, but to less educated legal professionals who interpret the laws. In the past, people thought of the initial Chevron decision as incredibly beneficial for scientific matters and for the environment. Chervon was removed recently with another Supreme Court decision that made this idea obsolete, removing professionals from the power …
