Solar flares are powerful eruptions of energy from the Sun that can cause disruptions to technology here on Earth, like communication systems, GPS, and power grids. To help manage these risks, it’s important to accurately identify and classify these solar flares before they cause problems. In our research, we focused on improving how we classify solar flares by looking at large sets of complex data collected over time. We used several techniques to find the most important factors that help us tell different types of solar flares apart. Each method has its strengths, so instead of relying on just one, …

Examining The Impacts Of Demographics, Individual Experiences, And Perceptions On Range Anxiety And Electric Vehicle Road Trips, Joshua Ward

All Graduate Theses and Dissertations, Fall 2023 to Present

Range anxiety is perhaps the most widely cited barrier to electric vehicle (EV) adoption and use. Range anxiety is generally defined as a general fear that an EV has insufficient battery range or that there is insufficient charging infrastructure to travel from one place to another. Although this barrier is widely cited, there is little research that investigates how EV drivers experience range anxiety and how it might vary based on personal characteristics, perceptions, and experiences. Data on long-distance EV trips is also scarce in the United States and mainly limited to personal stories of an EV road trip.

To conduct my research, I evaluated undergraduate wildlife curricula offered by 42 accredited universities listed on …

Multidecadal Data Demonstrate The Role Of Climate And Natural History Traits In Shaping Butterfly Phenology, Gbolahan Anthony Reis

All Graduate Theses and Dissertations, Fall 2023 to Present

Climate change is transforming the natural world, altering the timing of key events in the lives of plants and animals, such as when flowers bloom or when butterflies take flight. These timing changes, known as phenology shifts, can disrupt ecosystems and species interactions, creating ripple effects through food webs and biodiversity. While scientists have studied these shifts for decades, much of the focus has been on simple metrics, like the first or last day a butterfly is seen flying each year. However, these measures do not tell the whole story of how climate change is impacting the entire flight season …

The Geoarchaeology Of An Early Agricultural Landscape On Clear Creek, Fremont Indian State Park, Utah, Michael D. Bianchini

Quantitative Evaluation Of Baseflow Separation Methods Using An Integrated Hydrologic Model: A Case Study In A Snow-Dominated Watershed, Jihad Othman

All Graduate Reports and Creative Projects, Fall 2023 to Present

Baseflow, commonly referred to as the groundwater contribution to streamflow, constitutes approximately 50% of streamflow in mountainous regions of the Western United States. Accurately quantifying the amount of baseflow is critical for water management and decision-making, as it significantly impacts stream water quality, low flow availability, and ecosystem health. Traditionally, baseflow has been estimated using conceptual and automated baseflow separation methods, which are known to be both arbitrary and ambiguous, posing a challenge to validate them. In this study, we developed an integrated hydrologic model that seamlessly integrated the exchange between surface and subsurface flows to physically quantify the baseflow …

Few effective herbicides are available to control invasive grass weeds in seed production systems. Indaziflam is a pre-emergence herbicide capable of providing annual weed control for 3-5 years after application. Indaziflam is not labeled for use in seed production as little is known of the effect it will have. The purpose of this study was to measure total seed yield, seed germination, seed mass, and seedling vigor when applying 0, 40, 77, and 93 g ai ha^-1 of …

Evaluating The Stress System Of The Grieving Brain: Corticotropin-Releasing Factors And Partner Loss In Female Coyotes, Rachel Tong Xin Ning

Undergraduate Honors Capstone Projects

Forming social bonds is fundamental in helping us foster connections with others. The loss of a loved one often results in grief, stress, and loneliness, and the stress response system of the body has been implicated in the physiological symptoms associated with grieving. Corticotropin releasing factor (CRF) is the hormone that initiates the stress response in the body and acts at two different receptor subtypes CRF receptor (CRFR)1 and CRFF2. Many studies on CRF and social loss have been conducted in monogamous prairie voles, but studies in longer-lived monogamous mammals could improve understanding of the effects of losing pair bonds. …

Asian American Reproductive Rhetorics: A Rhetorical Analysis Of "The Farm" By Joanne Ramos, Mckinlee Armstrong

Undergraduate Honors Capstone Projects

Rhetorical scholars have long analyzed the idea of choice in the context of reproductive rights and have concluded that individual choice does not override the systematic barriers women of color face in accessing reproductive healthcare. Most Asian American rhetorical artifacts that have reached this same conclusion are case studies. I propose that analyzing Asian American fiction, specifically The Farm by Joanne Ramos, is just as necessary because fiction demonstrates the barriers that might exist in the future and how to prevent them from happening. The framework I use to analyze this text is the Asian American rhetorical concept of restiveness, …
