The Impact Of Early Exposure To Engineering Concepts In The Form Of Family, School Classes, And Stem Extracurriculars On The Long-Term Sense Of Belonging In Undergraduate Women In Engineering, Hannah Lloyd

All Graduate Theses and Dissertations, Fall 2023 to Present

Engineering continues to struggle with the underrepresentation of women, and many women who begin engineering programs report feeling isolated or uncertain about whether they belong. A strong sense of belonging has been linked to greater confidence, persistence, and success in engineering. This study examined how early experiences with engineering before college may influence students' sense of belonging later in their undergraduate engineering programs.

Using survey responses from undergraduate engineering students across the United States, this study explored several types of early exposure to engineering, including family influence, school-based engineering and STEM courses, extracurricular programs such as robotics clubs and engineering …

"In Any Other Circumstance I Am Not In Work Mode. I Am Clocked Out": Chappell Roan And The Objectified Persona, Aubry Louise

All Graduate Theses and Dissertations, Fall 2023 to Present

It is known that celebrities have influence on their audience’s attitudes and behaviors. Within the last few decades, multiple celebrities have created distinctions between their public/stage self and their private self, however, less is known about the ways that they differentiate between the two. This paper looks at celebrity public persona’s and how these persona’s influence their audience. I use Kayleigh Amstutz, otherwise known as Chappell Roan, as my case study. This thesis offers an analysis of how Amstutz talks about Kayleigh differently than Chappell within social media posts, interviews, and commentary from media outlets. I use the concepts of …

Integrated Soil-Water Processes And Irrigation Management For Agricultural Water Optimization In Semi-Arid Regions, Tejinder Singh

All Graduate Theses and Dissertations, Fall 2023 to Present

Water is one of the most important resources for agriculture in the western United States. In semi-arid regions, farmers depend on irrigation to grow crops, but water supplies are becoming less reliable because of drought, declining snowpack, groundwater depletion, and increasing competition for limited water. Improving agricultural water use is therefore not simply about applying less water. It also requires understanding where water goes after it enters a field, how long it remains available to crops, and how farmers can use that information to make better irrigation decisions. This dissertation follows water through irrigated agricultural systems to better understand how …

Resilience, Hope, And Posttraumatic Growth Among Yazidi Refugees, Erin Elizabeth Larson

All Graduate Theses and Dissertations, Fall 2023 to Present

Although it has been more than a decade since the Islamic State of Iraq and Syria (ISIS) imposed genocide upon the Yazidi people, an ethnic minority indigenous to Kurdistan, research on the psychological health of this community is lacking. While traumatic experiences and the accumulation of stressors can overwhelm one’s capacity for resilience, making it especially difficult for refugees to adapt and recover from their experiences. Posttraumatic Growth Theory posits that individuals may overcome such challenges and even undergo positive life transformations. Data were collected from Yazidi young adults using an online survey and examined the associations between resilience, hope, …

Developing A New Uas Method For Estimating Heat Exposure On Western Us Trails, Jared Young

All Graduate Theses and Dissertations, Fall 2023 to Present

Heat exposure and the risks to human health that stem from it have been studied extensively in the context of urban and occupational settings. Less studied however, is the effect of heat exposure in a recreational setting such as on hiking trails. What makes this fact more surprising is that recreation, especially in the Western US, is extremely popular, with national parks such as Zion and Arches bringing in hundreds of thousands of visitors every year. With millions of recreationists exposed to the hazard of heat every year, it is critical that recreationists are made aware of the dangers they …

Drought And Diet Breadth: Does Insect Specialization Influence Herbivory When Plants Are Under Stress?, Jakob Palmer

All Graduate Theses and Dissertations, Fall 2023 to Present

Climate change will alter precipitation worldwide, causing more frequent and severe drought events worldwide. Drought affects many ecological processes, including plant-herbivore interactions, which are critical to biodiversity and ecosystem health. A variety of plant characteristics can influence herbivory – such as how hairy, nutritious, or toxic a leaf is – and drought has been shown to alter many of these traits. Unique characteristics of herbivore species are also important: herbivores can either feed on a variety of plants (generalists) or a group of closely related plants (specialists). Specialists can cope with traits of the plants they eat, while generalists are …

Fostering Safe Space For Children In Online Navigation And Parent-Child Interactions, Rizu Paudel

All Graduate Theses and Dissertations, Fall 2023 to Present

As children and teenagers spend increasingly more time online, digital devices have become a major source of family friction. Disagreements frequently arise over privacy boundaries, and online activities. When these conflicts are unresolved, they often lead to broken trust and secretive behavior, leaving children vulnerable to digital harms like cyberbullying, toxic content, or account hacking. Therefore, it is important to create a safe and open environment for children where in order for them to share their feelings with parents. This dissertation investigates the human and technological dynamics of parent-child interactions, developing new ways to support collaborative conflict resolution and online …

Patterns Of Presidential Executive Orders And Democratic Quality: Evidence From The United States, 2017-2025, Karyn Sofie Sanford

All Graduate Theses and Dissertations, Fall 2023 to Present

Democratic backsliding has become an increasingly prominent topic in political science, yet relatively little attention has been devoted to how observable expressions of executive authority correspond with changes in democratic quality. Using the United States as a case study, this study examines the relationship between presidential executive orders and democratic quality from 2017 to 2025. More specifically, it investigates whether characteristics of executive orders correspond with changes in democratic quality, measured using the Liberal Democracy Index and the Judicial Constraints Index from the Varieties of Democracy (V-Dem) Project.

Presidential executive order issued between 2017 and 2025 were collected from the …

A Cfd-Dem Framework For Characterizing Nanoparticle Adhesion Effects On Creeping-Flow Permeability In Composite Manufacturing, Gavin Stoker

All Graduate Theses and Dissertations, Fall 2023 to Present

Modern aircraft, spacecraft, and high-performance vehicles are increasingly built from composite materials, engineered combinations of plastics and fibers that are lighter and stronger than traditional metals. Researchers are now pushing these materials further by mixing in microscopic particles thousands of times smaller than a human hair, called nanoparticles, to make them even tougher and more resistant to damage. The challenge is getting those nanoparticles distributed evenly. During manufacturing, liquid plastic resin is pumped through a network of tightly packed fibers, carrying the nanoparticles along with it. But nanoparticles tend to clump together and stick to surfaces as they travel, clogging …

Microbes In Pollination Systems: Effects On Pollinator Health, Floral Traits, Nectar Robbing, And Plant Fitness, Valerie Nicole Martin

All Graduate Theses and Dissertations, Fall 2023 to Present

Flowers produce nectar to attract pollinators, but nectar is also a habitat for yeasts and bacteria that arrive via pollinators, robbers, and other visitors. These microbes consume nectar sugars and release byproducts that change the smell and taste of nectar. Whether these changes affect how pollinators find and choose flowers, and whether they ultimately affect how many seeds a plant produces, is not well understood. In this dissertation, I studied how a common nectar yeast and a plant-associated bacterium affect the scent of wildflowers, the behavior of bumble bees and hummingbirds, and plant reproduction in montane meadows in central Colorado. …

Cadmium Biosorption By Fusarium Venenatum And Its Application In Functional Permeable Materials For Metal Removal, Bradley Lawson

All Graduate Theses and Dissertations, Fall 2023 to Present

Heavy metals are pollutants of increasing concern as continued industrialization and urbanization have escalated the discharge of these toxins into aquatic environments. Cadmium (Cd) is a metal of particular concern due to its acute toxicity and high mobility in aquatic ecosystems. Given these characteristics Cd poses significant health risks to both humans and aquatic ecosystems. The continued development of sustainable, low-cost remediation technology is imperative to manage metal pollution.

This research explores the use of fungal-based remediation systems to remove Cd from contaminated water. Living biomass of the filamentous fungus Fusarium venenatum was evaluated as a biosorbent material for Cd …

Seizure Susceptibility And Morphological Analysis Of A Missense Mutation In Hcfc1a Protein, Jose Manuel Fabela

Open Access Theses & Dissertations

Missense mutations in the HCFC1 gene cause methymalonic acidemia with homocystinuria cblX type (MIM#309541). cblX is an X-linked disorder that is associated with multiple phenotypes such as metabolic defects, failure to thrive, intractable epilepsy, facial dysmorphia, movement disorders, and intellectual disability. The mechanisms underlying these phenotypes are not completely understood. Here we used a zebrafish germline mutant allele (hcfc1aco64/co64) to study seizure susceptibility and adult brain structural malformations. Previous studies have established neural progenitor cell defects and hypoactive mechanistic target of rapamycin (mTOR) in this allele. Given the known role of mTOR in seizure phenotypes, we hypothesized that missense mutation …

Optimizing Urban Forestry Through Green Infrastructure: Tree Health And Water Retention In Ciudad Juarez Rain Gardens, Tomas Rogelio Lizarraga Ruiz

Open Access Theses & Dissertations

Urban green spaces (UGS) in arid regions face significant challenges due to water scarcity and extreme thermal demand. This study evaluates the efficacy of Nature Based Solutions (NBS), rain gardens and median strips, in enhancing the physiological resilience of urban trees in Ciudad Juárez, Mexico. Using a comparative framework, the research monitored a native evergreen (Dermatophyllum secundiflorum) and an introduced deciduous species (Morus sp.) across six planting treatments. Statistical analysis reveals that green infrastructure (GI) acts as a critical physiological accelerant. Trees situated within rain gardens and medians significantly outperformed those in restricted pot and sidewalk settings, maintaining higher stomatal …

Transnational Indigenous Environmental Justice: A Distant Comparative Study Of Nepali And U.S. Environmental Policies And Counter-Archives In Technical Communication, Shankar Paudel

Open Access Theses & Dissertations

This dissertation investigates how institutional communication, state bureaucracy, and Indigenous sovereignty intersect within Rhetoric and Writing Studies (RWS) and Technical and Professional Communication (TPC). Current TPC research increasingly focuses on social justice; however, the field still lacks ethical frameworks to deal with the complicated dynamics of transnational Indigenous Environmental Justice Communication (IEJC). This study addresses this gap by examining how two distinct Indigenous communities - the Tharus of Chitwan, Nepal, and the Ysleta del Sur Pueblo Tigua Indians of El Paso, Texas - communicatively navigate, contest, and resist state environmental policies.

Grounded in decolonial Distant Comparativism, Mestiza Consciousness, Rhetoric of …

Mija, Yes You Can: Faith And Motherhood In The Making Of A Scholar, Alejandra Salgado-Hernandez

Open Access Theses & Dissertations

This autoethnographic study examines how motherhood, faith, and borderlands identity shaped persistence throughout my journey as a Chicana mother-scholar in the U.S.-Mexico borderlands. Grounded in Borderlands Theory and Chicana Feminist Epistemology, the study centers lived experience, testimonio, spirituality, emotion, and embodied knowledge as legitimate forms of inquiry. Data included reflective journals, personal memory work, and selected family contributions. Through iterative narrative and thematic analysis, I organized experiences chronologically, coded recurring patterns and critical incidents, tested candidate themes across sources, and interpreted the resulting themes through the study's theoretical and scholarly literature. Four interconnected themes emerged: living in nepantla through borderlands …

An Analysis Of Mating Strategies In Rotifers Inhabiting Temporary Habitats, Ariel Bollinger

Open Access Theses & Dissertations

Reproduction is critical for organisms inhabiting ephemeral aquatic habitats where desiccation risk favors rapid and successful mating. Monogonont rotifers rely on sexual reproduction to produce diapausing eggs that withstand harsh conditions. I investigated how mating behaviors vary among populations of five rotifer species based on the hydroperiod of their habitat: Epiphanes brachionus and E. chihuahuaensis were sampled from habitats with short (SH) and long (LH) hydroperiods; Euchlanis dilatata was collected from a short (SH) and a permanent habitat; and Plationus patulus and Sinantherina socialis were collected from a long (LH) and a permanent (Perm) habitat. I hypothesized that SH populations …

Socially-Minded Investors And Corporate Behavior, Merritt B. Fox, Menesh S. Patel

Faculty Scholarship

Many equity investors are concerned with the world’s worsening social and environmental problems and are losing faith in the capacity of political institutions to respond. Corporate behavior is often contributing to these problems. Some investors, at least if fully informed as to costs and benefits involved, would favor corrective changes to corporate behavior even where that would lessen their investment returns. Two important questions arise: (1) given existing law, are such willing-to-sacrifice equity investors currently affecting firm behavior; and (2) should there be legal reform that makes firms more sensitive to these willing-to-sacrifice investors’ preferences? This Article seeks to answer …

An Exploration Of The Psychological Impacts Of Code-Switching, Cristina Culler

Electronic Theses and Dissertations

This dissertation is an interpretative phenomenological analysis of the lived experiences of four Black American adults who have frequently engaged in code-switching. Historically, code-switching has been perceived as a necessary skill that helps marginalized folx adopt the norms and practices of the dominant culture. As a result, code-switching has become a routine practice specifically for Black Americans who often occupy white spaces. Since code-switching has been perceived as a skill, the oppressive origins of code-switching often go unnoticed. Therefore, this dissertation examines code-switching through a critical lens that deems this practice a product of racist ideologies that prioritize whiteness. Through …

Development And Evaluation Of Alternative Mandrel Materials For The Fabrication Of In-House Silicone Vascular Models, Cole Capitani

Master's Theses

Dr. Kristen Cardinal’s Tissue Engineering Laboratory at California Polytechnic State University, San Luis Obispo develops tissue-engineered blood vessel mimics (BVMs) for preclinical testing of neurovascular devices. These BVMs are reliant on silicone vascular models that define the vessel geometry, support endothelial cell attachment, and allow devices to be evaluated in a controlled in vitro environment. Previous work in the lab established injection molding as a viable method for fabricating silicone vascular models and utilized acrylonitrile butadiene styrene (ABS) for sacrificial mandrels. However, this workflow relied on the use of acetone for mandrel dissolution, required single-use mandrels, had extended post-processing times, …

In Memoriam: Liah Greenfeld A Reflection From The President Of The Comparative Civilizations Forum, Bibi Pelić

Comparative Civilizations Review

It is with sorrow and gratitude that the Comparative Civilizations Forum dedicates this special 2026 Fall issue of the Comparative Civilizations Review to the memory of Professor Liah Greenfeld, who passed away in May of this year.

Professor Liah Greenfeld was a sociologist, an anthropologist, a political scientist — and more than any single label can hold. Across four decades at Harvard and then at Boston University, she built a body of work, from Nationalism: Five Roads to Modernity to The Spirit of Capitalism to Mind, Modernity, Madness, that stepped outside the boundaries the modern academy likes to draw. …

Using Assessments Intentionally With Consideration For English Language Learners, Elizabeth Ropp

Masters Projects

Assessment systems in the United States are failing English Language Learners (ELLs), and it has become apparent that action must be taken to try and right this injustice. There is a wide achievement gap between native English speakers and non-native English speakers when it comes to performance on state, local, and classroom assessments. Unfortunately, many teachers report that they do not feel adequately prepared to support ELLs both on classroom assessments and on mandatory state or local tests. With an ever-growing increase in ELL enrollment in American schools, it is imperative that teachers are given tools to help them better …

Promotion Architecture: A Deal Fairness Model Of Restricted Price Promotions, Shangwen Yi, David Hardisty, Dale Griffin, Thomas Allard

Research Collection Lee Kong Chian School Of Business

This research examines the effectiveness of two common types of restricted price promotions: threshold promotions (conditional on spending more than a threshold amount; e.g., “Get $5 off on orders of $10 or more”) and capped promotions (limited to a maximum dollar value; e.g., “Get 50% off, up to $5 per order”). Results from seven pre-registered studies, including one field study, show that threshold promotions lead to higher purchase intentions and conversion rates (but potentially lower purchase amounts) than comparable capped promotions—even though capped promotions are equivalent in maximal economic savings for the consumer—when the trigger value (the spending amount at …
