The curriculum was designed in alignment with the Cognitive Theory of Multimedia Learning (CTML), Empowerment Theory (ET), and Social Cognitive Theory (SCT) frameworks. These frameworks were used to determine the selection and sequencing of learning activities. As reflected in CTML principles, the use of texts, images, infographics, and videos enhances knowledge retention and information comprehension and helps prevent cognitive overload. Through activities, homework, and family engagement, the principles of ET were incorporated into the curriculum to facilitate participants’ perceived control over food-related decisions. Additionally, by applying the principles of SCT, the curriculum incorporates scenario-based questions, opportunities to engage with peers, …

To Chew Or Not To Chew: Effect Of Aposematism On Caterpillar Predation, Emily Kuehnl, Sadie Bivens, Rebekah Rowe, Olivia Halvorsen

Curiosity

Understanding predator-prey interactions offers insight into ecological dynamics and the selective pressures shaping traits that drive adaptive strategies. Aposematism is a well-established defense mechanism that combines conspicuous coloration with unpalatable chemical deterrents. This strategy is particularly effective against visually oriented avian predators, yet less is known about arthropods and mammals, which rely on other sensory cues. This study seeks to broaden the understanding of the effectiveness of aposematism by examining whether warning coloration in caterpillars will deter predation by birds, mammals, and arthropods. To achieve this, plasticine caterpillars representing cryptic (brown) and aposematic (yellow) phenotypes were deployed to trees in …

Motherhood Within The Patriarchal Family: Reconstructing Feminism Through "Frankenstein", Yasamin Osqueezadeh

Curiosity

In 1792, pioneering English feminist Mary Wollstonecraft published “A Vindication of the Rights of Woman,” arguing that women’s rights could only advance if women moved into the male-dominated public sphere, leaving behind household-centered education, traditional marriage structures, and the nuclear family dynamic. In 1818, Wollstonecraft’s daughter Mary Shelley published “Frankenstein,” in which she explored and critiqued women’s permanent and unacknowledged status as caretakers within their households. Whereas Wollstonecraft aimed to dismantle marriage completely, Shelley simultaneously argued to preserve the notion of family and marriage while also reconstructing the gender roles within those dynamics. Through the lack of female representation from …

Effects Of Uv Exposure On Fecundity, Survival, And Performance Of A Stored Grain Pest, Callosobruchus Maculatus, Colby Christensen, Fielding Mumford, Spencer Brinton, Anna Goates, Md Mirajul Islam

Curiosity

Seed beetles (Callosobruchus maculatus) are a pest of stored leguminous grains that can dramatically decrease yields. Management strategies to control infestations of C. maculatus are important for economic and food security. Radiation exposure is one possible management strategy that has shown promise. In two separate course-based undergraduate research experiences (CUREs), we tested how exposure to UV-C light affects C. maculatus fecundity, survival, and performance. Callosobruchus maculatus individuals were exposed to UV-C at two different life-stages: parent and egg exposure during oviposition and larval exposure during development. Whereas UV exposed two-week old eggs experienced slightly increased mortality, no significant …

Seed Endophyte Bacillus Atrophaeus Colonizes Root And Shoot Tissues Providing Antifungal Activity During Wheat Seedling Establishment, Anagha Wankhade, Zhiting Xu, Ashlynn Clark, David Britt

Biological Engineering Student Research

Seed-associated endophytes become active during germination, playing important roles as early colonizers of plant tissues and contributing to plant health while residing in a protective niche. In this study, we characterized a wheat-derived bacterial isolate, JunSE1L, to determine its functional traits and ecological role in the plant microbiome. The isolate was identified as Bacillus atrophaeus based on 16S rRNA analysis. JunSE1L exhibited nutrient-dependent plasticity in colony architecture, forming robust hydrophobic biofilms and pellicles under rich nutrient availability while swarming and forming thin, often dendritic colonies under defined nutrition. JunSE1L produced highly surface-active compounds that lowered the surface tension of water …

Klimczak, Robert Kay Cooper Jr., Wonkyung Kniffen, Maya Hareli, Cory Crane, Caroline J. Easton

Psychology Student Research

Digital mental health interventions (DMHIs) can help bridge treatment gaps experienced by young adults with co-occurring substance misuse and depression. However, it remains unclear whether engagement with these interventions differs for young adults with co-occurring conditions compared to those experiencing substance misuse or depression alone. To investigate this issue, we assessed working alliance and subjective engagement with a digital avatar-assisted cognitive-behavioral therapy (CBT) treatment platform (RITch^®CBT), comparing young adults with substance use, depression, and the co-occurrence of the two. A secondary data analysis was conducted on a sample of 99 young adults aged 18–28 years who presented at …

Measuring Disability Prevalence In Healthcare: A Study Comparing Two Disability Measures, Kristen L. Milefchik, Rhonda K. Dailey, Sharon Milberger

Developmental Disabilities Network Journal

People with disabilities experience significant health disparities and interventions are needed to address them. Measuring disability prevalence is an essential aspect of designing effective, data-driven healthcare strategies. Accurately measuring disability prevalence is challenging given disability is a complex phenomenon, with biological, social, environmental, and cultural components. Previous studies have compared a variety of disability status measurements and found that measurements were incongruent with each other. This study examines the concordance between disability status using two different measures: the nationally recognized American Community Survey (ACS-6) functional difficulty questions and one disability identity question. We used data from 3,621 adult patients participating …

Seasonal Body Composition And Neuromuscular Changes In High School Wrestlers: Medicine Balls For Fatigue Testing, Courtney Mccall Condie Carroll

All Graduate Reports and Creative Projects, Fall 2023 to Present

This study examines the effects a single wrestling season has on high school athletes’ body composition, muscle quality, membrane capacitance, and neuromuscular performance, and whether instrumented medicine balls are sensitive enough to serve as a field test for chronic fatigue. Twenty-five high school wrestlers (males=18, females=7) were recruited and assessed pre-season (Pre), mid-season (Mid), and end-of-season (Post). Outcome measures included body mass, fat-free mass, fat mass (via bioelectrical impedance spectroscopy), echo intensity (EI, via B-mode ultrasound) of the vastus lateralis (VL) and biceps brachii (BB), and countermovement rotational and backward-overhead throws with medicine balls instrumented with accelerometers.  Repeated measures ANOVA …

Long Term Changes In Elk Group Size And Composition (2002-2023) In Relation To Wolf Hunting Sucess, Kennedy Price

Undergraduate Honors Capstone Projects

Elk (Cervus elaphus) in Yellowstone National Park exist within a predator-prey system shaped by long-term interactions with wolves (Canis lupus). This predator-prey system represents an important model for understanding how predation influences ungulate behavior and social organization. Predators affect prey behavior through direct and indirect interactions and may cause long-term changes. What this study strives to answer is if predator success can have long term effects on prey grouping behavior and age-sex structure. In a previous study, wolves were found to be most successful hunting medium sized group of elk (20-49 individuals) in Yellowstone National Park. …

Developing Training And Streamlining Training Management Process For Smithfield Fire Department Employees In Aha, Naemt, And Aap Certifications, Michael Christopher Popa Ii

Undergraduate Honors Capstone Projects

The rapid operational expansion of the Smithfield Fire Department and EMS (SFD)—marked by a 300% increase in call volume and a transition to a fully professional, independent paramedic service—exposed critical systemic inefficiencies in clinical preparedness and personnel credentialing. This project addresses the "HALO Paradox," wherein high-acuity, low-occurrence emergencies require expert-level proficiency that cannot be maintained through call volume alone. Historically, the agency relied on fragmented, external continuing education (CE) that incurred high financial costs, lacked equipment standardization, and created administrative bottlenecks during biannual recertification cycles. The central objective of this capstone was to engineer a sustainable, in-house training infrastructure that …

Behind The Smile: A Qualitative Study On Dentist Burnout And Workplace Satisfaction In Cache Valley, Luke Thomas Hatch

Undergraduate Honors Capstone Projects

This qualitative research study examined satisfaction, stressors, and burnout among dental professionals in Cache Valley, Utah. Eight practitioners at various points in their careers were interviewed with a range of specialties including general dentistry (n = 3), pedodontics (n = 3), oral and facial surgery (n = 1), and orthodontics (n = 1). Analysis of the interviews showed that level of clinical autonomy was a primary factor influencing burnout levels. Stress levels in more experienced practitioners and owners tended to be lower than those who worked in multiple practices (multi-doctor) or with corporations. Individuals in these environments reported higher levels …

Nutrition Teaching Methods In Communities, Emery Fayth Rowles

Undergraduate Honors Capstone Projects

Community is a vital part of non-formal education. A sense of, longing for, and responsibility towards community draws individuals to participate in local services and classes. Community has been shown to have positive impacts on learning, self efficacy, and health.

Many of the techniques used in education mirror techniques used in building community—such as the use of small group discussions and cultural sensitivity—but with distinct differences in mindset. Most educational approaches see the acquisition and use of knowledge as the key purpose of the program and evaluate participants on an individual basis. This approach makes sense for programs meant to …

A Survey On Digital Reading Materials And Personal Study Of Christian Religious Texts, Teancum Price

All Graduate Theses and Dissertations, Fall 2023 to Present

Religion, including reading from religious texts such as scriptures, are a part of the daily lives of many people. Modern technology has influenced the way that this religious reading takes place, but its effects have not yet been studied. Existing research of the effects of technology on reading focus on topics such as reading comprehension, but the study of religious texts is often focused on achieving a religious experience, so the existing research does not capture the whole scope of these changes. In our study, we surveyed two universities (Utah State University and Abilene Christian University) to ask individuals how …

Spatial And Seasonal Concentrations Of Atmospheric Halogens Around The Great Salt Lake (2023/2024), Himalaya Sapkota

All Graduate Theses and Dissertations, Fall 2023 to Present

The Great Salt Lake (GSL), located in northern Utah, is one of the world's saltiest lakes and an essential resource for industry. It is also a significant hotspot for halogen emissions, including chlorine (Cl) and bromine (Br) from both natural and human sources. Although their concentrations in the atmosphere are low, they influence tropospheric chemistry by forming criteria pollutants such as ozone and particulate matter. These pollutants are detrimental to air quality, impacting public health and property. This study investigates the spatial and seasonal variability of halogen species (gas- and particulate-phase of Cl and Br) in the Northern Wasatch Front …

Impact Of Inhibiting Mitochondrial Calcium Uptake On Calcium Homeostasis And Postmortem Metabolism In Porcine Muscle, Fatema Rahaman Mishu

All Graduate Theses and Dissertations, Fall 2023 to Present

After harvesting the animal, pork muscle continues to undergo changes as it turns from muscle into meat. During this early period, the muscle uses up energy and produces acid, which lowers pH and can affect important quality traits such as color and how well the meat holds water. A key driver of these early changes is calcium, a natural mineral inside muscle cells that helps control contraction and energy use. In this study, we tested whether mitochondria (the cell’s “powerhouse”) help control calcium after harvest and, in turn, influence early postmortem changes in pork. We used a research compound (DS16570511) …

A Mixed-Methods Investigation Of Physician Compassion In Consultations For Chronic Primary Pain, Sarah Daehler

All Graduate Theses and Dissertations, Fall 2023 to Present

Chronic primary pain refers to physical pain that has no apparent organic cause, cannot be explained by another condition, and has associated psychological distress or functional impairment. Chronic primary pain is common and can significantly interfere with functioning, including occupational or social functioning. Research has shown that physicians struggle to treat this population, with many physicians reporting feeling unequipped and many patients feeling that their physicians are unhelpful and dismissive. Compassion may play a key role in improving these difficult interactions. The present study analyzed a sample of 99 participants with chronic pain and 100 healthy controls to learn more …

Utilizing Pine Needles To Compare Spatial Profiles Of Polycyclic Aromatic Hydrocarbons (Pahs) In Two Urban Areas, Autumn Jensen

Undergraduate Honors Capstone Projects

Polycyclic aromatic hydrocarbons (PAHs) are an important class of semivolatile air pollutants known for their adverse health impacts. This research used conifer needles as passive air samplers to create spatial maps of two Utah cities (Rose Park and Spanish Fork) to compare overall PAH exposure and identify any differences in their congener profiles or PAH “fingerprints”. Conifer needles were chosen due to their prevalence as a passive air sampler in previous research and their ubiquity in urban and suburban environments. Second year needles were collected and the concentrations are considered to be an annually averaged view of the PAH concentrations …

Uncertainty toward vaccination, long recognized as a public health concern in human medicine, is increasingly recognized within veterinary contexts, posing risks to both animal and community health. This literature review examines the development, causes, and implications of reduced vaccine confidence in veterinary medicine, with emphasis on small animal and some large animal practices. The review combines historical and current research to explore how vaccination perceptions have evolved among veterinarians and clients, and how factors such as the COVID-19 pandemic have shaped current attitudes.

The literature highlights recurring themes surrounding vaccine reluctance in veterinary settings. Client perceptions of safety, efficacy, and …

Effects Of Tourist Feeding On The Gut Microbiome And Ecophysiology Of Endangered Northern Bahamian Rock Iguana (Cyclura Cychlura), Erin Lucy Lewis

All Graduate Theses and Dissertations, Fall 2023 to Present

The lifespan and reproduction of an animal depends on maintaining a healthy physiology. The proportion of individuals that survive to an age at which procreation can occur is important to long-term stability of populations and contributes to species survival. Health in an animal is measured in a variety of ways, including through monitoring of the body’s physiological systems, as well as its ability to respond to invading pathogens, and through the different types of bacteria present in the gut. Relationships among those different health metrics have been discovered in recent years and have been found to play important roles in …

Exploring Cognitive Load Theory In The Post-Secondary Engineering Classroom, Gabriel Q. Van Dyke

All Graduate Theses and Dissertations, Fall 2023 to Present

Engineering programs often emphasize subject-matter expertise over pedagogical training, which can leave students struggling with course demands and contribute to retention challenges. This study applied Cognitive Load Theory (CLT) to examine how undergraduate engineering students experience the cognitive demands of their coursework compared to non-engineering classes. Using a sequential explanatory mixed methods design, cognitive load surveys were followed by interviews to address two research questions: (1) What are the differences in intrinsic and extraneous cognitive load levels between engineering courses and non-engineering courses taken concurrently by undergraduate engineering students? (2) How do engineering students perceive the unique challenges or benefits …

Beyond Morphology: Testing Molecular Assessment Of Macroinvertebrate Communities In Alpine Streams Of The Teton Range, Usa, Joshua Vollmer

All Graduate Theses and Dissertations, Fall 2023 to Present

Alpine streams and the macroinvertebrate communities that reside within them are threatened by the rapidly changing climate. Long-term monitoring of these communities is required to understand how they are changing and to predict their future trajectories. Historically, stream monitoring and assessment has been performed by collecting and identifying individuals using their morphological traits. However, in alpine aquatic ecosystems, distinct macroinvertebrate species often lack the morphological differences that allow them to be distinguished. DNA metabarcoding, an alternative method for identification which uses genetics instead of morphological differences, is not impacted by this issue, and therefore, may be better suited for alpine …

Effects Of Beaver Dams On Components Of Riverscape Health And Biodiversity In The Great Basin, Cashe C. Rasmussen

All Graduate Theses and Dissertations, Fall 2023 to Present

Networks of rivers and their floodplains (i.e., low-lying areas adjacent to rivers and streams that could plausibly flood) have been degraded, reducing the availability of freshwater and habitat for people and wildlife. Therefore, land managers are pursuing cost-effective restoration strategies, including partnering with beavers (Castor canadensis), to promote the health of these ecosystems and associated benefits. However, our understanding of beaver-mediated restoration benefits remains incomplete. Here, we compared locations along streams with and without beaver dams to measure the benefits of beavers in the Great Basin of the Western United States. We measured the effects of beaver dams …

An Autohistoria-Teoría Of A Pasifika Neptantlera, Belinda 'Ofakihevahanoa Fotu

All Graduate Theses and Dissertations, Fall 2023 to Present

This study was an autohistoria-teoría, a type of autoethnography, where I focused on my writing process as a Pasifika researcher creating a middle- grade fiction. As the researcher, my questions delved into how I engage in writing for a majority-culture dominated publication house in a Western-world writing genre while maintaining the cultural significance of the ancient Pasifika mythologies I reproduced and recontextualized in the novel.

Evaluating The Feasibility, Acceptability, And Preliminary Efficacy Of An Online Acceptance And Commitment Therapy Program To Improve Dietary Quality In Highly Stressed Adults, Francesca M. Knudsen

All Graduate Theses and Dissertations, Fall 2023 to Present

Stress can negatively affect both mental and physical health, which can increase the risk for chronic illness. When people feel stressed, they may also find it harder to make healthy food choices, which can further impact their health. Despite this, there are limited treatments designed to help people improve their dietary quality while managing stress. Acceptance and commitment therapy (ACT) is an evidence-based psychological approach that helps people respond more effectively to difficult thoughts and emotions while behaving in ways that are aligned with their personal values. This study tested whether a brief, online ACT-based program, combined with coaching phone …

Freshwater Mussel Reintroduction And Recolonization Habitat Modeling Using Hydraulic, Sediment And Geomorphic Parameters, Megan Elizabeth Dinicola

All Graduate Theses and Dissertations, Fall 2023 to Present

Freshwater mussels are an important group of aquatic animals that live within the riverbed, but their populations have been drastically reduced by habitat alteration and other anthropogenic activities. In an effort to bolster populations, river managers and biologists are using mussel reintroductions as part of their restoration efforts but there are gaps in our understanding of where to reintroduce mussels within a river to see them create self-sustaining populations. This research helps shrink this gap by better understanding the physical habitat needs and population expansion potential of subadult freshwater mussels, or the size of mussel that hatcheries grow for reintroduction, …
