A Critical-Constructivist Grounded Theory Exploration Of The Mental Health Experiences Of Individuals With Intellectual Disabilities In Post-Secondary Settings, Alyssa L. Decker
A Critical-Constructivist Grounded Theory Exploration Of The Mental Health Experiences Of Individuals With Intellectual Disabilities In Post-Secondary Settings, Alyssa L. Decker
Dissertations, 2020-current
Individuals with intellectual disabilities (ID) now have access to higher education, often through inclusive post-secondary education programs (IPSE), to increase employability and quality of life. IPSE programs, historically, have provided academic and life skill support and not mental health support within programs’ curricula. A recent review of IPSE programs reveals that if mental health services are included, they are often accessed through university health services. Transitioning from high school to college induces high levels of stress, which can exacerbate underlying mental health conditions. Mental health care is defaulted to an already overburdened college counseling center without the knowledge and skills …

All Peer-Reviewed Publications
Tunga penetrans (Linnaeus, 1758) (Siphonaptera: Tungidae) is an ectoparasitic flea whose adult females cause tungiasis by embedding into the host’s skin. Environmental, social and financial challenges in tungiasis endemic areas have left this disease neglected and lacking locally available control measures. One possible approach for controlling T. penetrans targets its off-host stages; however, surveillance tools for adult fleas are still lacking. Moreover, host-seeking cues and behaviour of adult T. penetrans remain largely unknown. In this study, we show that visual cues are attractive to adult T. penetrans. Newly emerged T.penetrans responded to light stimuli across a broad spectrum, ranging from …
Oak Savanna Expansion: Indigenizing Psu's Urban Landscape, Ash Herb
Oak Savanna Expansion: Indigenizing Psu's Urban Landscape, Ash Herb
University Honors Theses
Since time immemorial Indigenous Peoples have resided in what is now named Portland of the Pacific Northwest in the Willamette Valley. For hundreds of years, this forested Land has been colonized, razed to stumps and covered in cement in order to build the urban landscape. Due to such destruction on a broad scale, we are experiencing the results of climate catastrophe. By finding ways to reclaim our relationship with Land and returning to Indigenous epistemologies, our urban landscape has the opportunity to shift towards restoration and prosperity. Indigenous plants have existed here, supporting humans in a reciprocal relationship, for thousands …

Emergency Medical Services Mental Health: Causes Of Providers Leaving The Industry, Brian C. Selke
Emergency Medical Services Mental Health: Causes Of Providers Leaving The Industry, Brian C. Selke
Graduate Theses and Dissertations (2019 - present)
Employee resilience and mental health have become critical concerns in Emergency Medical Services (EMS) as workforce shortages increasingly threaten staffing stability and patient care. National Registry of Emergency Medical Technicians (NREMT) data indicates that more than 30% of eligible EMS providers did not recertify between 2020 and 2023, raising concerns about workforce sustainability. This study examines EMS providers’ intentions to leave the profession and identifies workplace factors associated with turnover. A statewide survey of more than 1,200 licensed EMS providers in Alabama was analyzed using regression techniques to evaluate the relationship between workplace conditions and turnover intentions. Results demonstrate that …
The Effect Of Specialty Malt On Dry-Hopping, Alexander Kivela
The Effect Of Specialty Malt On Dry-Hopping, Alexander Kivela
Master's Theses
Dry-Hopping is a modern and ever-increasing method to add hoppy flavors to beer. This is typically seen in pale ales and India Pale Ales (IPA’s). Most research has investigated the effect of dry-hopping only using pale malt, whereas most breweries used specialty malts to create a malty backbone to their beer.
The objectives of this research were to analyze the impact of specialty malts and their concentration on the efficacy of hop flavor and extraction, determined via gas chromatography and sensory analysis. Gas chromatography analysis was modeled after the ASBC Method Beer-48. Sensory analysis was performed via the 15cm line …
Impact Of Repeated Serotonin 6 Receptor Activation On Weight And Anxiety In C57bl/6j And Btbr Mice, Pedro Flores
Impact Of Repeated Serotonin 6 Receptor Activation On Weight And Anxiety In C57bl/6j And Btbr Mice, Pedro Flores
Electronic Theses, Projects, and Dissertations
Selective Serotonin Reuptake Inhibitors (SSRI) are the most common form of medication prescribed to people with anxiety disorders. One of the most common side effects is weight gain. This weight gain often leads to the suspension of treatment. This has led to studies focusing on specific serotonin (5-HT) receptor targets for modulating depression and anxiety. Studies examining 5-HT6 antagonist treatment have shown that they reduce body weight as well as produce brain specific changes. Less is known regarding 5-HT6 receptor agonists, although previous literature has shown that exposure to high doses produces weight loss but not at lower doses, while …
From Genes To Streams: Mitochondrial Approaches To Population Monitoring Of The Santa Ana Sucker Catostomus Santaanae, Mariana Antonio
From Genes To Streams: Mitochondrial Approaches To Population Monitoring Of The Santa Ana Sucker Catostomus Santaanae, Mariana Antonio
Electronic Theses, Projects, and Dissertations
This study was developed to use aquatic environmental DNA (eDNA) as a tool to detect the presence of the Santa Ana sucker (Catostomus santaanae), a federally threatened fish species, across the Santa Ana River in Southern California. Environmental DNA is any genetic material that an organism sheds into the environment. We can get an idea of what aquatic species are present when sampling water at a given site. We sequenced the complete mitochondrial genome (mitogenome) of the Santa Ana sucker and designed custom DNA primers to improve eDNA detection accuracy. These primers were selected based on high genetic …
Hope Kit Program, Monica Reuber
Hope Kit Program, Monica Reuber
Capstone Experience: Master of Public Health
Suicide is a leading cause of death in adolescents and young adults, with a disproportionate burden of those deaths in rural areas such as Kansas. High rates of depressive symptoms, suicidal thoughts, and suicidal attempts, combined with a shortage of mental health providers, emphasize the need for community-based intervention.
This capstone is designed to develop a plan for Hope Kits, a proposed suicide prevention program, among youth in grades 7-12 in Sheridan County, Kansas to improve coping skills, promote help-seeking behavior, and reduce suicide risks.
A logic model guides the program development, which aligns with available literature and Social Cognitive …

Evaluating The Discus Throw As An Ancient Greek Combat Training Tool Through Modern Performance Metrics, Daniel R. Porter
All Graduate Reports and Creative Projects, Fall 2023 to Present
This study’s purpose was to explore the correlations between peak velocity in a rotational throw with a medicine ball, peak force (PF) and rate of force development (RFD) in an isometric mid-thigh pull, time to failure in a plank test, and peak velocity in a sword thrust task, which was also tested for reliability. Twenty-seven recreationally trained male participants between the ages of 18-35 completed the study. The sword thrust task was significantly correlated with the medicine ball throw (p = 0.012, r = 0.475, r² = 0.226, 95% CI [0.724, 0.116]) and PF (p = 0.045, r …
Flexible Grazing: Evaluating Stocker Cattle As A Drought Management Tool For Utah Livestock Producers?, Ross Israelsen
Flexible Grazing: Evaluating Stocker Cattle As A Drought Management Tool For Utah Livestock Producers?, Ross Israelsen
All Graduate Reports and Creative Projects, Fall 2023 to Present
Drought is a persistent concern in the western United States, often leading to reduced forage production, overgrazing, and economic challenges for livestock producers. This study evaluates the economic feasibility of incorporating stocker cattle as a flexible drought management strategy under varying forage conditions across four Utah grazing locations: Park Valley, Nephi, Vernal, and Beaver. The Rangeland Analysis Platform (RAP) was used to estimate annual forage production and stocking rates from 2001 through 2025. Four stocking-rate scenarios (100%, 75%, 60%, and 50% cow–calf stocking rates) were evaluated using a Net Present Value (NPV) framework to compare the economic performance of traditional …
Isolation, Identification, And Enzymatic Screening Of Fungi From Utah Dryland Soils For Industrial And Waste Valorization Applications, Jessica Lorena Silva Cuero
Isolation, Identification, And Enzymatic Screening Of Fungi From Utah Dryland Soils For Industrial And Waste Valorization Applications, Jessica Lorena Silva Cuero
All Graduate Reports and Creative Projects, Fall 2023 to Present
Agricultural waste accumulation presents environmental challenges but also opportunities for biological valorization into value-added products. Fungi are particularly well-suited for this purpose due to their capacity to produce extracellular enzymes involved in the degradation of complex organic substrates. Dryland ecosystems represent a promising source for bioprospecting microbes capable of producing such enzymes. Drylands harbor a high diversity of extremophilic microorganisms that can withstand harsh conditions, extreme heat, UV, and low nutrients using unique adaptations. This suggests that these microbes are resilient and capable of surviving under varying conditions and still produce enzymes for biotransformation. The objective of this study was …

Food Insecurity And Parent Engagement In Pediatric Therapy: A Comparative Study Of Feeding, Speech-Language, And Combined Services, Kendra Kendra Rosales
Open Access Theses & Dissertations
Pediatric feeding disorders and food insecurity represent two compounding challenges for families navigating pediatric therapy services, yet their intersection has received little empirical attention. This study examined food insecurity rates across three pediatric therapy groups and explored the relationship between food insecurity and parent engagement in therapy. A cross-sectional online survey was administered to 175 caregivers of children actively receiving feeding therapy only (n = 34), speech-language therapy only (n = 93), or combined feeding and speech-language therapy (n = 48). Food insecurity was assessed using the USDA Household Food Security Survey Module: Six-Item Short Form, and parent engagement was …
Divergent Belowground Strategies Of Savanna Grasses Under Varying Fire Regimes, Abigail C. Schmidt
Divergent Belowground Strategies Of Savanna Grasses Under Varying Fire Regimes, Abigail C. Schmidt
All Graduate Theses and Dissertations, Fall 2023 to Present
Savannas are unique ecosystems, where trees and grasses live together across the landscape, not quite forming full forests or open grasslands. The ability for trees and grass to coexist is largely the result of widespread disturbances, such as fire. Fire in savannas is largely thought of in how it maintains plants above ground, however, fire also plays a key role in ecosystem and plant processes belowground. First, fire can change how soil nutrients, namely phosphorus, are cycled. Phosphorus is a key nutrient that plants need to function, and plants acquire phosphorus through their roots. Frequent fire can enhance phosphorus availability, …
Bridging Animal Production And Human Nutrition: How Production Ecology Shapes The Nutritional Quality Of Terrestrial Animal Foods And Human Omega-3 Status, Joseph Vinod Varre
Bridging Animal Production And Human Nutrition: How Production Ecology Shapes The Nutritional Quality Of Terrestrial Animal Foods And Human Omega-3 Status, Joseph Vinod Varre
All Graduate Theses and Dissertations, Fall 2023 to Present
The question at the center of this dissertation is simple: does the way food is produced change the quality of the food itself in ways that matter for human health? Across a series of studies on bison meat, eggs, and human dietary intervention, the answer was yes. This work began with a broad look at the modern food system and the nutritional consequences of industrialized diets. In particular, it focused on the growing imbalance between omega-6 and omega-3 fatty acids in the Western diet. This balance matters because omega-3 fats support heart, brain, and immune health, and diets high in …

Youth Agricultural Engagement And Its Association With Dietary Diversity, Household Food Insecurity, And Nutritional Status In Southwest Nigeria, Sherif Olasoji
All Graduate Theses and Dissertations, Fall 2023 to Present
Youth remain underserved in nutrition research, policy, and programming despite being an integral part of the food systems. While the nutrition-sensitive agriculture framework has been established, there is limited evidence demonstrating how youth engagement in agriculture can serve as a pathway to improve nutritional outcomes. The study assessed youth agricultural engagement and its association with household dietary diversity, household food insecurity, and nutritional status in southwest Nigeria.
Using a cross-sectional design, data on socio-demographic characteristics, agricultural engagement, dietary diversity, household food insecurity, body mass index, and skin carotenoids were collected from 143 youth aged 15 to 35 from Ekiti, Osun, …
Advancing Management Strategies For Two Promising Mason Bee Species (Osmia Ribifloris And Osmia Bruneri) For Berry Pollination, Miranda L. Jones
Advancing Management Strategies For Two Promising Mason Bee Species (Osmia Ribifloris And Osmia Bruneri) For Berry Pollination, Miranda L. Jones
All Graduate Theses and Dissertations, Fall 2023 to Present
Bee management can broadly refer to human manipulation of one or multiple parts of a bee’s lifecycle. Managing honey bees, commonly referred to as beekeeping, is responsible for providing most pollination for global food crops. However, using more than one bee species for crop pollination can have many benefits. Benefits include better crop pollination and insurance in case one bee species underperforms or its population collapses. Some bees within the genus Osmia are already widely managed for crop pollination because their developmental lifecycle allows bee managers to readily deploy pollinating bees in sync with varying crop blooms, and for certain …
Three Essays In Discrete Choice Analysis: Valuation, Attention Level, And Spatial Heterogeneity, Marcelo Pignatari
Three Essays In Discrete Choice Analysis: Valuation, Attention Level, And Spatial Heterogeneity, Marcelo Pignatari
All Graduate Theses and Dissertations, Fall 2023 to Present
Understanding how people value food labels and environmental goods is essential for designing policies, incentives, and market mechanisms that improve the well-being of the population. In this study, we found that a local label indicating that fruit was produced in Utah makes Utahns value strawberries, gala apples, and dried tart cherries more. An organic label has a similar effect, which is especially strong for dried tart cherries. In contrast, a freshness label only increases value for fruits with a shorter shelf life, such as strawberries. We also found that people who chose to access clarifying information about what these labels …
Integrating Space Use And Demography To Support Management Of An Endangered Alpine Ungulate, Danielle J. Berger
Integrating Space Use And Demography To Support Management Of An Endangered Alpine Ungulate, Danielle J. Berger
All Graduate Theses and Dissertations, Fall 2023 to Present
The places animals choose to live affect the food they find, the dangers they face, and the weather conditions they experience. These experiences influence whether individual animals survive and reproduce, which in turn affects the size and health of animal populations. Although scientists have long believed that animal movements play an important role in population trends, there has been limited real-world evidence showing this connection. Advances in GPS tracking technology now allow researchers to follow animals over long periods and better understand how movement influences survival. Using 20 years of GPS tracking data from the endangered Sierra Nevada bighorn sheep …

Incorporation Of Dairy Ingredients Into Chocolate And Caramel: Impact On Product Quality, Shelf Life, And Consumer Acceptance, Taelie Kennedy
All Graduate Theses and Dissertations, Fall 2023 to Present
Incorporating next-generation milk powders like milk protein isolate (MPI) and milk protein concentrate (MPC) into confections can increase protein content. Milk permeate powders (MPP) are byproducts of the production of high-protein dairy ingredients (MPC and MPI). Typically considered waste streams, growing awareness of sustainability has increased interest in the use of MPP in food. There is minimal research on the use of these ingredients in confections.
This study evaluated the effects of incorporating milk protein powders and MPP into chocolate and the effects of replacing granulated sugar with MPP in caramel on product quality and consumer acceptance.
Chocolate batches were …
The Effects Of Psychological Stress On Gut Health In Mice Fed Either A Healthy Diet Or The Total Western Diet, David Keenan Thomas Prescott
The Effects Of Psychological Stress On Gut Health In Mice Fed Either A Healthy Diet Or The Total Western Diet, David Keenan Thomas Prescott
All Graduate Theses and Dissertations, Fall 2023 to Present
The Total Western Diet (TWD), a rodent diet designed to model the typical American dietary pattern, has been shown to worsen inflammation and colitis severity in mice. Psychological stress has also been associated with increased intestinal inflammation, barrier dysfunction, and alterations to the gut microbiome. The goal of this study was to determine whether combining the TWD with psychological stress would further worsen colitis severity and alter the gut microbiome. To investigate this, mice were fed either a healthy control diet or the TWD and exposed to psychological stress using a social disruption stress model. Colitis was induced using established …

Impact Of Chronic Stress And Nutrition On Functional Connectivity And Neural Networks In Young Kichwa Children From The Ecuadorian Amazon Rainforest, Matthew L. Cook
All Graduate Theses and Dissertations, Fall 2023 to Present
Early childhood is a critical period for brain development. Positive and negative experiences during this time can have lasting effects on learning, health, and well-being. However, most research on children’s brain development has been conducted in wealthy, industrialized nations, leaving important gaps in our understanding of how children develop in other cultural and environmental contexts.
This study examined brain development in Indigenous Kichwa children living in two rural communities in the Ecuadorian Amazon Rainforest. The goal was to better understand how chronic stress and nutrition may influence a child’s developing brain during early childhood. Children participated in noninvasive brain assessments …
The Influence Of Habitat And Individual Specialization On Mountain Lion (Puma Concolor) Hunting Strategy In A Multi-Prey System, Hannah B. Klugman
The Influence Of Habitat And Individual Specialization On Mountain Lion (Puma Concolor) Hunting Strategy In A Multi-Prey System, Hannah B. Klugman
All Graduate Theses and Dissertations, Fall 2023 to Present
There is a growing recognition that animal species considered generalists (having a broad and varied diet), are actually specialists, a collection of individuals with different preferences and strategies known as specializations. The diet of a specialist depends on the variety and quantity of available food options, and their own ability to take what they need. Mountain lions (Puma concolor) are known for their ability and tendency to hunt large prey, such as elk (Cervus canadensis) and mule deer (Odocoileus hemionus), but despite the fact they overlap with other potential large prey, like feral horses …
Drought And Diet Breadth: Does Insect Specialization Influence Herbivory When Plants Are Under Stress?, Jakob Palmer
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 …
Formulation And Analysis Of Physiochemical And Sensory Properties Of Ready-To-Mix Whey Protein Phospholipid Concentrate Beverage, Chris Jaquin
All Graduate Theses and Dissertations, Fall 2023 to Present
Whey protein phospholipid concentrate (WPPC) is commonly recovered as a coproduct in filtration process whose aim is to obtain whey protein isolate (WPI) from whey protein concentrate (WPC). Whey protein phospholipid concentrate is high in milk fat globule membrane (MFGM), which has been shown in rodent and human studies to have a variety of physiological benefits, including an increase in exercise capacity. Whey protein phospholipid concentrate is currently considered as an underused dairy coproduct, with most of it either being disposed of or used as animal feed. This research consisted of incorporating WPPC in a protein shake–like beverage at a …
Gender And Bill Changes In Congress: An Analysis Of Women-Sponsored And Women's Issue Bills, Kipling B. Corry
Gender And Bill Changes In Congress: An Analysis Of Women-Sponsored And Women's Issue Bills, Kipling B. Corry
All Graduate Theses and Dissertations, Fall 2023 to Present
Women have faced historical disadvantages in American politics, generally, and in their positions as lawmakers. Bills in Congress, proposed by men and women alike, often undergo various textual changes before becoming law. This thesis explores how the gender of lawmakers and the gendered issues found within bills affect these changes. Are bills that are proposed by women disproportionately altered more than bills proposed by men? And are bills that concern women’s policy issues disproportionately altered more than bills that do not? This thesis investigates these questions by first presenting two original datasets and a full bill text file that introduce …
A Data-Driven Nutrient Density Scoring Framework For Beef Using Principal Component Analysis, Teja Vuppala
A Data-Driven Nutrient Density Scoring Framework For Beef Using Principal Component Analysis, Teja Vuppala
All Graduate Theses and Dissertations, Fall 2023 to Present
Beef is one of the most nutrient-rich foods in the human diet, providing high-quality protein, iron, omega-3 fatty acids, B vitamins, and a wide range of other compounds important to health. However, current nutrition scoring systems used on food labels were designed to compare different foods to one another — for example, beef versus broccoli — and do not work well for judging the nutritional quality of different beef samples relative to each other. A grass-fed steak and a conventionally-finished steak can carry nearly identical Nutrition Facts panels while differing substantially in their content of omega-3 fatty acids, vitamins, and …
Microbes In Pollination Systems: Effects On Pollinator Health, Floral Traits, Nectar Robbing, And Plant Fitness, Valerie Nicole Martin
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. …
Seizure Susceptibility And Morphological Analysis Of A Missense Mutation In Hcfc1a Protein, Jose Manuel Fabela
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 …
