Bottles, Butterflies, And Biomass: Recycled Glass Sand, Microbial Additions, And Herbivory Effects On Milkweed Growth, Kealey Skinner

Honors Theses

Plant-soil-microbe interactions are integral components of ecological networks and drive ecosystem function from the bottom-up. Whereas herbivores regulate ecosystem function from the top-down, having opposing and potentially complementary effects on ecosystem function. My thesis sought to understand how below-ground microbial communities contribute to herbivore preference and plant biomass across varied soil substrates. My thesis asked: how do substrate and soil microbial communities influence herbivore preference and plant biomass accumulation on swamp milkweed (Asclepias incarnata)? To address this question, seedlings of A. incarnata were sown in 2.5 cm wide × 10 cm deep pots filled with either natural beach sand or …

Comparative Investigation Of Bacterial Adhesion On Medical Device Thermoplastics, Dev V. Mehta

Honors Theses

This project will focus on determining if differences in bacterial cell wall composition influences adhesiveness to thermoplastic materials used to construct patient orthotic splints. Bacteria with decreased adhesion are unable to remain bonded to orthotic splints, increasing its ability to transfer to a patient’s wound, leading to an infection. Antibiotic resistant bacteria used in this investigation included gram-positive cocci vancomycin-resistant (VRE) Enterococcus faecalis, methicillin-resistant Staphylococcus aureus (MRSA), and gram-negative rods extended-spectrum beta-lactamase (ESBL) Escherichia coli and Pseudomonas aeruginosa. Each test bacterium is a major pathogen causing healthcare-associated infections (HAIs). Saline, artificial perspiration, and ascites fluids were used to determine the …

Capacity Reduction Factors For Steel Beam Ends With Holes, Kevin Saleh Makubuli

Masters Theses

The presence of holes at steel beam ends can decrease the nominal resistance (capacity) of beam ends. Codes such as AASHTO LRFD and AISC include equations for evaluating the nominal resistance of steel beam ends. While these equations are appropriate for as-designed beam ends, they may not apply to deteriorated beam ends, such as those with holes. Thus, this study aims to develop procedures to calculate the capacity of steel beam ends with holes. First, the FEA of an as-designed beam is performed for capacity evaluation (numerical result). The latter is compared with the analytical result (as-designed beam capacity) to …

The Trade-Off Between The Fear Of Judgment (Stigma) And The Intention To Engage With Ai-Driven Hiv/Aids Information: Evidence From Bangladesh And Nigeria, Abdullah Mohaimen

Masters Theses

This study explores the relationship between Fear of Judgment (FOJ), understood as perceived stigma, and Intention to Engage (EI) with an AI-driven chatbot providing HIV/AIDS information. Stigma often discourages individuals from seeking information or discussing sensitive health issues, creating barriers to prevention and education. AI chatbots offer a potential solution by enabling anonymous, accessible, and non-judgmental interactions. This study examines whether FOJ reduces users’ willingness to engage with such technology and whether cultural context shapes this relationship. Data were collected from young adults in Bangladesh and Nigeria (N = 56) through an anonymous online survey using a simulated chatbot, Lifeline. …

Distribution Mapping And Modeling Of The Invasive Japanese Knotweed, Jossalyn Rogalski

Masters Theses

This thesis investigates the distribution of invasive Japanese knotweed across Michigan. This plant poses significant challenges to land management due to its rapid growth, environmental impacts, and difficulty of removal once established. Using geographic information systems (GIS), remotely sensed data, and secondary environmental datasets, this research maps current infestations and analyzes key factors influencing the species’ growth and dispersal, such as soil composition, hydrology, land use, and a range of environmental variables, including climatic (annual mean temperature, temperature seasonality, annual precipitation, precipitation seasonality), elevation, vegetation and hydrological indices (NDVI, EVI, NDWI), percent tree cover, and distance to roads.

Transformer Vulnerability To Geomagnetically Induced Currents Using Layered Soil Conductivity Models, Junior A. Sterling

Masters Theses

Geomagnetically induced currents (GICs) pose a significant threat to modern power transformers connected to long high-voltage transmission systems, particularly in regions with low subsurface electrical conductivity. During geomagnetic disturbances (GMDs), time-varying magnetic fields induce surface electric fields that drive quasi-DC currents through grounded transformer neutrals. These currents can bias transformer cores, leading to saturation, waveform distortion, and potential system instability. Despite extensive research, the role of regional Earth conductivity in shaping electric fields and transformer response remains an area requiring deeper investigation.

This study analyzes how contrasting Earth conductivity profiles influence GIC magnitude and transformer saturation risk using two representative …

Does The Party Label Matter? Partisanship, Election Timing, And Ballot Drop-Off In Municipal Elections, Joelle Francis Whitaker

Masters Theses

This project examines if party labels drive participation in municipal elections. Progressive Era reforms removed partisan labels in attempts to weaken party machines and simplify local governance. Many cities continue to implement these reforms today. However, existing research suggests that party labels provide important informational and mobilizing cues that should increase turnout, especially in low-information elections. Using a comparison of four Michigan municipalities, this paper evaluates how partisan and nonpartisan systems shape local election turnout. The results show that the relationship is more complicated than expected. While party labels will still matter for how voters make decisions, election timing emerges …

Separating And Identifying Delta-8-Thc And Delta-9-Thc On Gc/Ms, Ann Schmidt

Honors Projects

Delta-8-THC and delta-9-THC are two psychoactive compounds found in marijuana products which are only distinguishable from each other by alternating the location of a single double bond.  This makes them a challenge to separate and identify as different compounds using the GC/MS.  These isomers are legally recognized as the different compounds, so being able to identify delta-8 and delta-9 THC separately is crucial to forensic analysis. The goal of this research project is to optimize an Intuvo 9000 GC connected to a standard MS to be able to separately and prominently identify delta-8-THC and delta-9-THC in a sample.  This was …

The Carolina Rain Porch: A Southern Vernacular Considered, Jackson M. Dent

All Theses

The “rain porch,” also known as the “Carolina porch,” is a distinctive vernacular porch type concentrated in South Carolina’s Pee Dee region and sporadically found in neighboring states. Despite its strong regional identity, the form has received little sustained scholarly attention. This thesis presents a comprehensive study of the rain porch, examining its origins, chronology, geographic distribution, and architectural variation. Defined by an extended porch roof supported by free-standing columns set forward of porch deck, the rain porch represents a purposeful environmental adaptation within nineteenth-century domestic architecture. The research integrates archival sources, National Register of Historic Places survey data, mapping, …

Taking A Deeper Look: Attributing Tonal Values Of Photolumens To Their Emulsions Using Scanning Electron Microscopy, Anna M. Moore

All Theses

This thesis examines whether tonal variation in photolumens made with historic silver gelatin photographic papers can be linked to differences in elemental composition. Photolumens are cameraless photographic images created by placing objects directly on light-sensitive paper and exposing them to ultraviolet light. Because expired and historic darkroom papers often produce unpredictable colors and tones, this study asks whether visually defined tonal groups also show measurable chemical differences.

Twenty historic paper samples were exposed, documented, and sorted into five tonal groups based on visible image characteristics. Each sample was then analyzed using scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS) …

The Dam Plan Matters: Proactive Policy And Nature-Based Solutions For Deliberate Dam Removal, Leah Kaisner

All Theses

Throughout the United States, the dam infrastructure is aging out of their lifespan. This increases risk of loss of life and property, particularly with dam failure. Dam aging necessitates proactive planning methods is needed to prepare communities for dam removal effects rather than responding to failure disasters. This thesis studies how city planners and local officials can use nature-based solutions, river restoration, and resilient policy tools to prepare for upstream dam removal. I created a Dam Removal Preparedness (DRP) Framework for integrating nature-based solutions, resilient policy, and restoration methods and used it as a scoring system to assess community plans’ …

Developing A Decision-Making Tool For Breast-Feeding Mothers Whose Babies Have A Cow's Milk Protein Allergy, Rachel M. Griffith

Human Nutrition and Hospitality Management Undergraduate Honors Theses

Cow’s milk protein allergy (CMPA) is one of the most common food allergies in infancy, affecting an estimated 2–3% of infants, including those who are breastfed. Many symptoms of CMPA overlap with gastrointestinal disorders and lactose intolerance, leading to frequent misdiagnosis and unnecessary maternal dietary restriction. Breastfeeding mothers who eliminate dairy to manage suspected CMPA often face nutritional deficiencies, emotional strain, and financial burden, while infants risk poor growth if symptoms are not properly addressed. Breastfeeding is viewed as the optimal source of nutrition for infants providing many cognitive benefits and positive maternal effects like decreased stress and risks of …

Prospective Memory Skills Of College Students With And Without Adhd, Nicole Llamas-Carrillo

Theses & ETDs

Attention Deficit/Hyperactivity Disorder (ADHD) is associated with impairments in executive functioning (EF), working memory, and time related processing. These deficits create challenges in prospective memory (PM) which is the ability to remember a future task. PM is essential for everyday functioning, and prior research has shown that adults with ADHD already experience PM difficulties, and expands on the difficulties ADHD individuals have with planning. It has been suggested that temporal myopia (TM), a cognitive bias prioritizing immediate goals rather than future goals, is expanding on explaining why individuals with ADHD are vulnerable to PM difficulties. The higher the TM (also …

Theses & ETDs

This study examined the relationship between conservative political ideology and key aspects of romantic relationships, including gender role attitudes, expressions of intimacy and affection, communication styles, and partner preferences. Based on prior research suggesting that conservatism is associated with traditional social values and relationship behaviors, four hypotheses were proposed predicting significant associations between political conservatism and these variables. A sample of 334 adults in the United States completed an online survey consisting of the Attitudes Toward Women Scale, Index of Sexual Satisfaction, Affectionate Communication Index, Communications Patterns Questionnaire, and the Ideal Partner and Ideal Relationship Scale. ANOVA analyses were conducted …

The Proximal Effects Of Blood Flow Restriction On The Infraspinatus Muscle Cross-Sectional Area And External Rotation Strength, Adam James Zavalney, Noah Matthew Gaffy, Tyler Grensteiner

Physical Therapy Scholarly Projects

Purpose/Hypothesis: Blood flow restriction (BFR) is a method of training that utilizes a tourniquet style cuff to limit the amount of blood flow to a working muscle during exercise. This method of training allows an individual to train at lower intensities while still gaining similar results to more traditional types of training. It has been shown in research that low intensity BFR has several benefits to structures distal to the level of the tourniquet, but minimal research has been conducted to investigate the benefits to proximal structures. This study is aimed at examining the proximal effects of BFR training on …

Using narrative inquiry, six Filipino American family units (6 children; 8 parents) participated in individual and joint dyad interviews and Culturally Responsive Musical Inquiry (CRMI), in which families co-composed an original song. Findings indicate that K–12 schooling …

The Legitimacy Of International Law: A Kantian-Rawlsian Account, Taeyang Lee

Philosophy

This paper aims to answer the question of whether international law has legitimacy and value despite the absence of global centralized coercive enforcement and whether the concept of legitimacy developed in domestic law theory can be applied to international law. By avoiding the two extremes that claim that international law is nothing more than a non-binding agreement, or that it requires the centralized enforcement of a world government, I will defend a middle position that explains the moral binding force of international law when it satisfies conditions of legitimacy. Drawing on Kant's Universal Principle of Right and Ripstein's three defects …

Examining Institutional And Personal Barriers To Women's Participation In The U.S. Foreign Service In Comparison To Scandinavian Countries, Isabella R. Thompson

Political Science Undergraduate Honors Theses

What explains women’s underrepresentation in the United States Foreign Service? The United States Foreign Service Act of 1980 claims that the foreign service needs to be “truly representative of the American people throughout all levels.” Women also constitute the majority in such fields as political science and international relations, which often lead to a career in foreign service. If there are no legal obstacles to women’s entry into foreign service and women are the majority in the education systems that lead to a career in foreign service, then why are women not participating? Existing explanations focused on structural factors such …

Comparatively Exploring Journalism And Oral Histories As Modes Of Advocacy For Marginalized Communities, Miceala R. Morano

Journalism Undergraduate Honors Theses

In this study, four oral history interviews produced at the Pryor Center and news stories produced by four local media outlets were comparatively analyzed using software program MAXQDA. Each was qualitatively coded for expressions of identity, community and advocacy. These three key themes were determined through bottom-up processing, meaning the overarching themes were selected after each interview was listened to twice.

The results of this process were then used to determine the key similarities and differences between oral history and journalism, and how both practices can be used to accurately capture the narratives of marginalized communities. These findings were combined …

Sex Differences In How Celebrity Crushes Bolster Self-Perceived Mate Value, Madyson M. King

Psychological Science Undergraduate Honors Theses

Previous research indicates that parasocial relationships provide surrogate connections for individuals to where they offer various psychological benefits. Some benefits include self-esteem and improved body image, which may be connected by such relationships facilitating attainment of one's ideal self. Given this benefit of social surrogacy, it could be possible that a vicarious romantic connection with a parasocial figure may similarly bolster one's mate value if that relationship were to move an individual closer to a personal ideal. We predicted that engagement with a celebrity crush would be associated with a heightened mate value. A community sample of men and women …

Negation And The Backfire Effect, Caden Fowler

Psychological Science Undergraduate Honors Theses

Quick! Do not think of a polar bear. Did you think of a white bear? As Russian author Fyodor Dostoevsky wrote in his 1863 essay “Winter Notes on Summer Impressions,” “[when tasked to not think of a polar bear] you will see that the cursed thing will come to mind every minute.” The consequence of negation without context (i.e., unlicensed negation; Levine & Hagaman, 2008) is what has come to be referred to as the “backfire effect,” a phenomenon where correcting misinformation strengthens belief in that information rather diminishing it (Ecker, et al., 2020). Fake news and misinformation in …

The Effects Of Cannabidiol (Cbd) On The Social, Cognitive, And Physical Facets Of Anxiety Sensitivity, Ezri Rathbun

Psychological Science Undergraduate Honors Theses

The current study investigated how repeated administration of 300mg of cannabidiol (CBD), when compared to a placebo, affects the social, cognitive, and physical facets of anxiety sensitivity (AS), a characteristic that reflects fear of the consequences of anxious arousal. Prior work suggests CBD may have anxiolytic effects that may be specific to the social aspects of anxiety. Thus, it was hypothesized that, that, relative to placebo, CBD would reduce self-reported AS-social concerns, but not AS-cognitive or AS-physical concerns, compared to baseline. Participants (N= 79; 52 women; M_age = 22.06) with elevated perceived stress were randomly assigned to 14 …
