Evolution Of Nematode Prey Chemotaxis Behavior Across Different Environments, Hailey R. Smith

Honors Theses

Climatic conditions in the near future are projected to be warmer, with more frequent and intense weather events. This will substantially alter the environments in which organisms must integrate specific information to find essential resources. Many organisms rely upon chemical signals to orient towards attractive resources through a mechanism called chemotaxis. How different environmental conditions, like temperature, impact this process will be important to understand as environments change. I conducted a laboratory evolution experiment with the model nematode Caenorhabditis elegans to see how success in chemotaxis assays changes over time when selected under different temperature regimes (normal laboratory temperature, increased …

Studying More, Not Less: Rethinking Test Anxiety In Undergraduate Biology Courses, Kailey E. Reeves

Honors Theses

This study investigates the relationships among test anxiety, study behaviors, and metacognitive evaluation in undergraduate biology courses. While prior research has established that study strategies and metacognition influence academic performance, less is known about how these factors interact with test anxiety in undergraduate Biology courses. Guided by the student approaches to learning (SAL) and metacognition frameworks, this study examines whether test anxiety is associated with the type and number of study strategies students use, as well as their ability to evaluate their own learning and preparedness. Using a convergent parallel mixed-methods design, data was collected from 205 students enrolled in …

The Impact Of Patient Navigation On The Hepatitis C Care Continuum In Underserved Populations: A Scoping Review, Deauntaye Jones

Honors Theses

Hepatitis C virus (HCV) remains a significant public health concern and is a leading cause of cirrhosis, hepatocellular carcinoma, and liver transplantation when left untreated. Although direct-acting antiviral therapies have made HCV curable for most patients, many underserved populations continue to experience barriers to diagnosis, linkage-to-care, treatment completion, and sustained virologic response (SVR). This study evaluated how patient navigation programs influence progression through the HCV care continuum among underserved populations. Relevant studies published between 2014 and 2025 were identified through searches of PubMed and Embase using terms related to HCV, patient navigation, linkage-to-care, underserved populations, and treatment outcomes.

How Ai Governance Differs Between Regime Type, Jackson T. Guillou

Honors Theses

This thesis will examine how artificial intelligence (AI) regulation and development differ across political regime types, arguing that governance outcomes are fundamentally shaped by institutional political structures. This thesis will draw on comparative frameworks analyzing democratic and authoritarian systems. This thesis will also include case studies of the European Union, the United States of America, China, and Russia. The study finds that democratic regimes tend to emphasize transparency, accountability, and rights-based regulation of AI. This often results in slow regulation of AI, but it is more ethically legitimate and constrained. In contrast, authoritarian regimes prioritize centralized control, strategic coordination, and …

Neurophysiological Signatures Of Perceived Control In The Human Brain: An Electroencephalography Study, Megan Staehling

Honors Theses

Perceived control is defined as the belief that one’s actions can influence the outcomes in the environment. It plays an important role in decision-making, motivation, and emotional regulation. Previous studies suggest that perceived control shapes how the brain processes both reward and punishment stimuli. However, the neural mechanisms underlying this process are still unclear. The present study examined the neurophysiological correlates of perceived control during a decision-making task. Electroencephalography (EEG) was used to record the neural activity of twenty-nine undergraduate students while they completed the Choice Task. Participants associated visual cues with different levels of control over trials involving monetary …

Controlling Fiscal Destiny: Evaluating The Effect Of State Tax Composition On Resilience During Defined Shock Period, Calloway R. Bills

Honors Theses

State governments operate under strict fiscal constraints that limit their ability to respond to economic downturns through borrowing or monetary policy, making tax composition a key determinant of fiscal stability. This paper evaluates how variation in state tax revenue composition affects fiscal resilience during economic shocks, focusing on the Great Recession. While prior research shows that individual tax instruments differ in cyclicality, less is known about how overall tax structure shapes revenue performance during and after shocks. Using a panel dataset of U.S. states from 1988 to 2024, this study measures resilience through two outcomes: the magnitude of revenue decline …

"For Their Effectual Exclusion": Oregon, Racial Exclusion, And Citizenship In The Mid-Nineteenth Century, Riley M. Littleton

Honors Theses

In light of Oregon’s admission to the Union as the only state to receive congressional approval with a racial exclusion clause in its constitution, this project seeks to examine the constitutional and cultural thought that ultimately led to the stamp of approval on the thirty-third state. In the past, Missouri had attempted a similar maneuver, seeking to bar free Black Americans from entry; Congress had not allowed it, believing that the provision violated the U.S. Constitution’s Privileges and Immunities Clause. This project investigates what changed congressional opinion between Missouri and Oregon’s respective times.

In researching contemporary literature to understand local …

Just War Theory And Coercive Non-Proliferation: Ethically Evaluating Nuclear Prevention Efforts, P. Walker Jacklin

Honors Theses

This thesis examines the ethics of coercively addressing non-nuclear states who are attempting to acquire nuclear weapons. Nuclear weapons pose a serious danger on a global scale, so ethical analysis should balance these consequences with the coerciveness of state intervention. Just War Theory provides a useful framework that balances these considerations.  Using the criteria of Just War Theory, this thesis examines two 21st century non-proliferation operations: Operation Orchard and Operation Midnight Hammer. I find that Operation Orchard fails the criteria of Just War Theory, while Operation Midnight Hammer satisfies the criteria. Making this determination is ethically risky, however, because our …

This program is analyzed through careful consideration of regulatory review and ethical theory. Key policies governing Expanded Access are examined alongside scholarly discussions of pediatric autonomy and parental authority.

A case study of ONC201, a now-approved investigational drug, is used to illustrate how Expanded Access …

How To Fail At Faith, Olivia R. Bacon

Honors Theses

How to Fail at Faith tells the story of Ruth, a girl in middle school who begins to doubt her faith in the Christian God. With these doubts come existential questions, fear, and, most strangely, a voice that narrates Ruth’s everyday activities inside her head. Ruth is scared this voice means she is only a character inside a story, but is even more scared to tell her parents about her internal struggles. As Ruth grapples with her faith, this “narrator” becomes a tangible support amid uncertainties. Ruth surrenders to trusting God after fighting her doubts, and discovers that her mysterious …

Peace Agreements, Provisions, And Profit: How Peace Agreement Provisions Impact Foreign Direct Investment Inflows, Wendi M. Sheehan

Honors Theses

There are many provisions that post-civil war states may include in peace treaties. This paper seeks to analyze the inclusion of three specific provisions– political power sharing and political institutions, rule of law/property rights, and infrastructure and reconstruction– and their impact on the resulting foreign direct investment inflows into a post-conflict nation over the course of ten years. I hypothesize that states that include one or more of these provisions will subsequently experience higher FDI inflows. To test this theory, I used the peace agreement information from the PA-X Peace Agreements dataset and FDI inflow information from the United Nations’ …

Bax Activation Through The N-Terminal Bh3-Like Domains Of Vdac1 And Vdac2, Autumn A. Peters

Honors Theses

Voltage-dependent anion channels (VDACs) are central to mitochondrial function by mediating metabolite diffusion across the mitochondrial outer membrane (MOM). Two isoforms­­­­­­­­­­­,­­­­­­­­­­­­­­­­­­­­­­­­­­­­ VDACs 1 and 2, are also implicated in apoptosis based on interactions with Bcl-2 family proteins that control this process, including Bax and Bcl-xL. Activation of the pro-apoptotic protein Bax by interaction with ‘BH3-only’ proteins, such as Bim or Bid, induces MOM permeabilization to signal apoptosis, yet accumulating evidence indicates VDACs 1 and 2 may also affect Bax. We discovered that the VDAC N-terminal domains contain high sequence similarity to the conserved BH3 domains within Bcl-2 family members that …

Energy Materials Health Monitoring With Interpretable Machine Learning, Osumanu Musah Mohammed

Honors Theses

Reliability and the lifecycle of energy materials have become key concerns for sustainable, decarbonized power systems [1]. More recent reports on photovoltaic (PV) device technologies, fuel cells, hydrogen storage, and novel composite materials have indicated that material deterioration is a constraint on large-scale exploitation and cost-effectiveness, rather than on energy conversion efficiency [2], [3]. The energy infrastructure of tomorrow needs to be smart and efficient; however, more to the point, it needs to be self-aware, self-diagnostic, and able to overcome any form of degradation before breaking down [4]. The US dilemma is also directly related to federal concerns. That is …

The Effect Of A Superficial Biochar Layer On Soil Radon Exhalation: A Preliminary Investigation Into A Passive Residential Radon Mitigation Strategy, Nicholas Richmond Nelson

Honors Theses

Residential radon exposure is a leading cause of lung cancer worldwide, yet home testing and mitigation remain infrequent. Active mitigation systems can be costly, and existing passive radon-resistant construction techniques, while cost-effective, are not always sufficient to reduce indoor radon to below the recommended EPA threshold of 4.0 pCi/L (148 Bq/m3). This initial work examines the potential for a superficial biochar layer placed beneath a house foundation during construction to reduce soil radon exhalation and subsequent indoor radon concentration. Biochar is also being explored as an admixture to concrete, and this study investigates radon transmission through concrete with varying biochar …

Recovering Sn From Ultrafine Tails At Mina San Rafael, Peru, Angelica Plenge

Honors Theses

San Rafael is currently the only mine producing tin (Sn) in Peru, operating two concentrators. In the first, called the San Rafael plant, tin concentrate is produced through gravity separation circuits consisting of jigs, spirals, and Mozley tables, followed by reverse flotation, where sulfides are floated while cassiterite (78.77% theoretical tin content) is depressed. Material containing tin values is then directed to a desliming circuit, where the pulp density is adjusted prior to sulfide reverse flotation. The tailings from this stage are subsequently processed through another flotation circuit but, in this case, the Sn is floated. Cycloning is applied throughout …
