Title: ““An Overview of The Prevalence of Disordered Eating Habits and Eating Disorders In Female Collegiate Athletes: A Scoping Review””
Abstract: Eating disorders and disordered eating habits are increasingly common in sports, particularly among female collegiate athletes. Pressures to be aesthetically appealing or meet weight class requirements are factors that drive the onset of this issue. Other biological, sociocultural, and psychological factors have been identified as precursors. Although some research exists concerning these habits, no research to date examines the post-pandemic prevalence of these disorders in female collegiate athletes. The objective of this research is to provide an overview of the prevalence of disordered eating habits and eating disorders in female collegiate athletes since 2020. Our methodology used the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews checklist. We searched SportDiscus, APA PsychInfo, MEDLINE, Gale Academic One File, Health Premium Research Collection, ERIC, JSTOR, OmniFile, Sage, and ScienceDirect using the following search terms: female collegiate athletes AND (disordered eating OR disordered eating behaviors OR disordered eating habits OR feeding disorder OR eating disorder). All titles were uploaded to Covidence, a review software. Six reviewers screened titles and abstracts for inclusion with two reviewers per title. Two will resolve conflicts. All will extract data from the final studies to a spreadsheet: author, year of publication, journal title, objectives, study design, setting, participants, type of data collected, variables, main results relevant to the research question, and funding. Each study will be charted by two researchers; for conflicts, there will be a third reviewer. We will narratively summarize our findings for publication in a peer-reviewed scientific journal.

Title: “Muscle Oxygen Saturation In United States Collegiate Female Gymnasts During Floor Exercise”
Kinesiology
ABSTRACT: Muscle metabolism is often studied in athletes participating in traditional sports such as American football or basketball. However, there is little research in gymnastics and even less in female artistic gymnastics. Although gymnastics is usually classified as an anaerobic sport, the 90-sec floor routine demands contribution from the aerobic energy system. This contribution from the aerobic system is unstudied and can be a limiter of floor performance. The purpose of this observational study is to describe muscle oxygen saturation (SmO2) levels in the vastus lateralis and observe if there is a relationship between SmO2 levels and scores on the floor exercise. We hypothesize that higher SmO2 values will correspond to higher average floor routine scores. To be included, gymnasts must have participated in the 2023-2024 National Collegiate Athletic Association Division I (NCAA DI) season and were apparently healthy according to the American College of Sports Medicine guidelines. The head coach approached her team of 22 women; nine voluntarily consented. The study protocol included two days at the William & Mary Williamsburg Gymnastics training facility. On day one, consent forms were signed, we acquainted participants with the study, and we measured anthropometrics and demographics. On day two, the head coach decided the order of participation. Each gymnast performed their usual warm-up of about 15min. To the first gymnast, we attached a Moxy Monitor with Dynamic Tape to the vastus lateralis of her dominant leg. The Moxy Monitor uses near-infrared spectroscopy to measure real-time SmO2 at the capillary level. We synced the Moxy to PerfPro Studio software, which showed live SmO2 readings. The gymnast performed her floor routine. We then removed the Moxy from her and attached it to the next gymnast until all gymnasts were measured. We describe demographics and anthropometrics with counts, percentages, means, and standard deviations. We report average, minimum, and peak SmO2. We obtained each athlete’s 2023-2024 NCAA DI competition scores on the William & Mary public-facing website. We calculated an average of their floor scores throughout the season. Our sample characteristics were: 161.7 +/- 5.7cm tall, 63.0 +/- 7.3kg, 20.4 +/- 0.7yrs, 5 (55.6%) were right and 4 (44.4%) were left-leg dominant, 1 (11.1%) was a first-year, 2 (22.2%) were second-years, 6 (66.7%) were third-years, and 0 (0.0%) were fourth-years. Since there were fewer than 10 participants, to maintain confidentiality, we report the average of those nine values for SmO2 results. Average SmO2 was 45.1 +/- 9.7%, the average minimum SmO2 was 30.7 +/- 11.8%, and average peak SmO2 was 63.9 +/- 6.3%. We found a positive trend where high values of average, minimum, and peak SmO2 trended toward higher floor scores throughout the competitive season. Our results are the first to describe muscle oxygen saturation levels in NCAA DI female gymnasts. The variation in SmO2 values in gymnasts may indicate various limiting factors of performance: cardiac, respiratory, or muscular oxidative capacity. Future research must identify what is predictive of top floor performance, e.g., consistently high SmO2, or the ability to sustain low levels of SmO2. These results can benefit athletic stakeholders to identify potential physiological limiters and tailor training protocols for maximum performance.

Title: “The Ethics of Automation: How Many Jobs Should We Really Replace?”
Business
ABSTRACT: The rise of AI and robotics threatens to erase millions of jobs within our lifetime – but who decided this was inevitable? This hard-hitting presentation exposes the human cost of unchecked automation and demands urgent action. While corporations race to replace workers with cheaper, faster machines, we’re facing a crisis of unemployment, inequality, and lost purpose that could destabilize our entire society. Through shocking case studies—from Amazon’s ruthless warehouse robots to AI systems that discriminate against women and minorities—we reveal how automation is being weaponized against workers. The numbers don’t lie: 47% of U.S. jobs could vanish, with low-income workers bearing the brunt. But this isn’t progress—it’s corporate greed disguised as innovation.
We propose concrete solutions to take back control: mandatory robot taxes, worker protections, and strict bans on automating caring professions. The choice is ours. Will we surrender to a dystopian future of mass joblessness, or fight for an ethical automation revolution that puts people first? The time to act is now—before the machines take over for good.

Title: “Distribution of High Elevation Owls In The Davis Mountains, Texas”
ANRS
ABSTRACT: Several mountain ranges within the Chihuahuan Desert receive more precipitation and experience cooler temperatures than the surrounding lowland desert. This “sky island” effect allows for more diverse ecosystems within the mountain range, including canyon watersheds and pine forests, which support high-elevation bird species uncommon to the area. Due to the rugged and remote nature of the Chihuahuan Desert mountains, the distribution and occurrence of high-elevation species is poorly understood, especially for nocturnal birds. This study aims to evaluate the occurrence of nocturnal bird species in the Davis Mountains, particularly flammulated (Psiloscops flammeolus), northern saw-whet (Aegolius acadicus) and Mexican spotted (Strix occidentalis lucida) owls. Data collection will occur at the Davis Mountains Preserve between March and August, which spans the breeding seasons of the target species, when calls are more frequent. Data collection began in 2024 and will continue through 2025. Owls will be surveyed using autonomous recording units (ARUs). ARUs will be placed in locations where owls are expected to be, based on previous placement, terrain, and vegetation. There are 25 ARUs total, which will be set to record during peak call times (2-3 hours after sunset and before sunrise). Preliminary results show detections of all 3 target species at the Davis Mountains Preserve. Following analysis, ARU recording times and placement can be honed further based on frequency of owl calls and species/habitat associations.

Title: “Dung Beetle Diversity In Grazing Regimes of Desert Grasslands”
ANRS
ABSTRACT: Dung beetles (family Scarabaeidae) are keystone species and ecological assessors of rangelands. Dung beetles decompose feces by actively breaking down dung pats by burying and processing dung through tunneling underground, ultimately, incorporating nutrients into the soil, a crucial process for nutrient cycling in ecosystems. These invertebrates are significant to livestock operations as their coexistence with grazing ruminants is necessary to improve the overall health of grassland ecosystems. This study took place at the Mimms Ranch Unit of the Dixon Water Foundation, a 6,474.97 hectare property nestled in the Marfa Grasslands of Far West Texas. The ranch has rotational grazing regimes with a control continuous grazing pasture, allowing for the opportunity to compare the response of dung beetles to different grazing systems. Therefore, this study examines the presence and diversity of dung beetles between the different grazing systems. Beetles were collected in 120 randomized pitfall traps across two different soil types within each of the two grazing systems. We used an Analysis of Variance to see if there was a difference in amount of beetles between treatments (P > 0.05). Results suggest there is a difference between treatments with rotational regime having a higher number of dung beetles. While the data collected from this study shows there is a difference in response of beetles, further research is needed to correlate the relationship between grazing systems, vegetation, and dung beetles properly.

Title: “America At Work: The Lasting Le WPA In The Big Bend Region”
History
ABSTRACT: The Works Progress Administration (WPA), established in 1935 as part of President Franklin D. Roosevelt’s New Deal, was a transformative force in American history. Designed to combat unemployment during the Great Depression, the WPA provided millions of jobs that reshaped the nation’s infrastructure and cultural landscape, leaving a lasting imprint on communities both large and small. Through its ambitious public works projects, the WPA employed over 8.5 million people between 1935 and 1943. Workers built roads, bridges, schools, libraries, and parks, fundamentally improving the nation’s public infrastructure.
Beyond its immediate economic impact, the WPA helped strengthen national resilience during one of the country’s most challenging periods. By offering jobs to both skilled and unskilled workers, it instilled a sense of purpose and unity across the nation. Even after the program ended in 1943, its influence endured, with many WPA-funded buildings, roads, and artistic works still in use today. Towns such as Alpine, Texas, continue to house WPA-era structures, serving as a testament to its enduring legacy. More than a job creation effort, the WPA demonstrated how large-scale public investment could drive economic recovery and shape the future of a nation.

Title: “An Investigation Into Yukio Mishima’s “Sun and Steel: Aesthetics of the Collective Identity”
English
ABSTRACT: This paper considers the aesthetic theory of the body proposed in Yukio Mishima’s “confidential criticism,” “Sun and Steel.” Mishima argues that society has separated the mind from the body, creating individuals who reject the sun in favor of a nocturnal state. Therefore, given that the body reflects the state of the mind, Mishima illustrates that the body may be taught to achieve a classical physique the same way the mind obtains a classical education. However, Mishima carries his study of the body to the collective identity: the experience of tragedy, a sense of duty, and a self-awareness of death shared by others. Consequently, this paper seeks to unravel Mishima’s attempt to unify “art and action” within the collective body, death, and language.

Title:“The Case Defense for State of Georgia v. Cassandra Bjorge 2017 Appeall”
Criminal Justice
ABSTRACT: On April 8th 2017, Cassandra Bjorge and Johnny Rider murdered her grandparents, Wendy and Randall Bjorge, in their house in Lawrenceville, Georgia. The couple hadn’t originally fled the scene after Rider committed the murders, instead locking the doors and remaining in the house. Although they stayed in the house days after, once they decided to leave, they attacked Johnny’s sister’s house next, and it was there where they were shortly caught by the police and arrested. When Cassandra Bjorge was interrogated by police detectives, she casually admitted to being at her grandmother’s house and assuming guilt for not stopping Rider from killing her grandparents. Although the presentation is meant to show a representation of facts that lead to the guilt of Johnny Rider for murdering her grandparents, the thesis of the case is to prove why Cassandra should be found not guilty in an appeal due to definitive evidence that suggests the guilt of Johnny Rider. The prosecution team argue for death by electric chair or life in prison without parole for the ex-boyfriend to Cassandra Bjorge. Methods of conviction include the evidence to be proven in the presentation to find Rider guilty, and not Cassandra. Findings will indicate the heavily use of assault with deadly weapon to prove the involvement of her ex-boyfriend in committing the murders and the lack of evidence to support Cassandra Bjorge killed her grandparents. Findings call for the verdict being delivered as not guilty for Cassandra Bjorge given the fact that DNA tracings can only prove what matches to her story of her ex-boyfriend delivering the blows with a deadly weapon to have killed her grandparents. The verdict in the theory in this case would appeal for 30 years in the mental hospital for Cassandra Bjorge with possibility of parole after 25 years served. The presentation is going to accurately reflect that the sentencing for life in prison without parole be overturned due to lack of physical and forensic evidence.

Title: “Nursing School Chronicles: A Podcast Through The Eyes of Nursing Students”
Nursing
ABSTRACT: SRSU nursing students explore the differences and similarities between rural and urban nursing in a podcast. The students discuss the unique challenges faced in both settings, such as limited resources in rural areas versus the high patient volume in urban hospitals. The podcast highlights how nurses in rural areas often take on more responsibilities, including emergency care and working with fewer staff. In contrast, urban nurses have access to more advanced technology and specialized medical teams but may experience stress from overcrowded hospitals. Both types of nursing require strong problem-solving skills and the ability to adapt, but they each have distinct environments that shape the way care is provided. The episodes allow listeners to gain a deeper understanding of what it’s like to be a nursing student in both rural and urban areas, showing how each setting impacts patient care and nursing practices. Additionally, the podcast explores how nurses in both areas build relationships with their communities, with rural nurses often forming close connections with patients over time and urban nurses having the opportunity to care for a broader range of diverse populations. Through personal stories and expert insights, the podcast offers a comprehensive view of the nursing profession, emphasizing the importance of adaptability, teamwork, and empathy in both rural and urban settings.

Title: “The Effects of Ecotourism on Groundwater Resources in Brewster County, Texas”
Geology
ABSTRACT: Brewster County, located in Far West Texas, is culturally and geologically complex with diverse habitats and attractions, featuring the towns of Alpine, Marathon, Terlingua, and Lajitas, as well as the Rio Grande and the Big Bend National and Big Bend Ranch State Parks in the southern region of the county. Located within the Chihuahuan Desert, Brewster County receives ~ 17 inches of precipitation annually. Most public and private water supplies are sourced from the “igneous” aquifer and an unnamed Cretaceous aquifer. Via the Texas Water Development Board (TWDB) and the county’s Groundwater Conservation District (GCD), enabled by the Texas Water Code Chapter 36, Brewster County is able to monitor and regulate its groundwater use. With the rise in tourism in the county in recent years, there has been concern regarding long-term groundwater sustainability and availability. The population of the county is not projected to increase, but there is an evident increase in transient water users, presumably increasing transient groundwater consumption. Our research aims to estimate this increase in groundwater use through the Residential Gallons Per Capita Per Day equation developed by the TWDB, Texas Commission of Environmental Quality, and the Water Conservation Advisory Council. Using eCognition Object-Based Image Analysis and change-detection algorithms, we intend to conduct a longitudinal study to monitor the development of short-term rental properties in Terlingua and Lajitas. A qualitative study will also be conducted to gain insight into the local communities’ perspective on groundwater use in the region. All these components will provide the Brewster County GCD with essential information about the undocumented increase in transient groundwater use.

Title: “New and Old Technologies for Soil Erosion Control: Using Remote Sensing to Monitor the Effectiveness of Trincheras”
Geology
ABSTRACT: Wind and/or rainfall weather events displace topsoil when ground vegetation cover is scarce, leading to rangeland degradation and limiting the cycle of ecological processes. Understanding how and where soil erosion occurs is essential for targeting efficient management strategies for restoring rangeland ecological processes and vegetation communities. Remote sensing using fine scale imagery has accelerated rangeland research and presents an opportunity to monitor soil erosion processes. Our research goal is to explore the effectiveness of fine scale remote sensing at measuring displacement of topsoil volumetric data in drainage channels. We did this by estimating soil sediment accumulation within drainage channels using imagery acquired from a cellphone device. To test the accuracy of this method to detect soil accumulation, we added 41.4 liters of soil on the ground and took measurements before and after for comparison. Using a cellphone device, we captured oblique angle imagery taken from multiple perspectives of the channel before and after soil placement. We then constructed a 3D model using SFM (Structure-from-Motion) image processing to create surface and terrain models from before and after soil placement. We then used the surface and terrain models to calculate soil sediment accumulation. We estimated controlled soil addition to within .1 liters, which was within 99.998% accuracy. Following the feasibility test, we installed 100 trincheras across 20 different stream channels to represent different characteristics of slope and catchment area. This methodology can give us a volumetric data of soil accumulated at trinchera locations and guide land stewards to fine scale their management improvements in places where erosion control structures can maximize efficiency of topsoil retention.

Title:“Stream Discharge Estimates for Matonoso Creek, South Presidio County, Texas”
Geology
ABSTRACT: Matonoso Creek is a tributary to Alamito Creek, south of Marfa in Presidio County, Texas. This catchment is 6,617 hectares with a channel length of 32 km. We used 1 m digital elevation models (DEM), ArcGIS Pro and python scripting to assess the channel conditions in the creek and to estimate discharge at various locations along the channel. The ArcGIS Pro component created cross section graphs and contributing area for specific locations along the channel. After visual analysis of the cross sections, python code was used to determine the discharge at selected cross sections using estimated water surface elevations based upon cross section shape and visual identification of bank full stage. Manning’s equation was used for this step. The results will be used to assist in restoration projects designed to minimize channel erosion and to increase sediment deposition.

Title: “The Role of Soil Type and Grazing Systems in Shaping Desert Grassland Ecosystems”
Natural Sciences
ABSTRACT: Desert grasslands are critical ecosystems that support diverse wildlife species and provide valuable resources for livestock production. However, the Trans-Pecos is subjected to habitat degradation if managed incorrectly because of the variable precipitation in desert grasslands. The choice of grazing system has long been debated as to which has the most benefits in meeting a landowner’s goal and sustaining healthy rangelands. The two most common grazing systems, rotational and continuous, can modify and sustain rangeland health. Therefore, this project aims to identify and compare grass species cover, annual standing crop production, species composition, forage nutrition, and soil moisture between a long-term rotational, continuous, and deferred grazing system in a desert grassland of the Trans-Pecos. Grasses were collected at the end of the 2023 and 2024 growing season. Random stratified sampling was used to place 690 0.5 m2 plots in all grazing regimes confined to two soil types (Marfa-clay-loam and Musquiz-clay-loam). Volumetric soil moisture was taken along with all other floristic data at each plot. Linear regression analysis showed that a continuous system will increase soil moisture between all systems overall and has the greatest increase on Musquiz-clay-loam with little to no effect on Marfa-clay-loam. A rotational system with higher overall unique species decreases soil moisture on both soil types compared to the deferred and continuous. With further analysis, this study will reinforce the importance of considering soil types when developing grazing systems and allow for grazing to be used as a management tool to conserve and restore grasslands.

Title: “Spatial Ecology of Aoudad and Mule Deer: Responses to Population Management Efforts”
Natural Sciences
ABSTRACT: The interactions between non-native aoudad (Ammotragus lervia), native desert bighorn (Ovis canadensis), and mule deer (Odocoileus hemionus) are poorly understood. However, they are presumed to compete at greater population densities and may shift space use to mitigate resource competition. We sought to understand how aoudad population reduction affects the space use of both aoudad and mule deer, relative to preferred desert bighorn habitat. In April 2023, we captured and collared 40 aoudad and 40 mule deer in the Chinati and Quitman Mountain ranges in the Trans-Pecos and fit them with tracking collars that recorded locations every 2 hours. To assess aoudad and mule deer interactions, we lethally removed aoudad (n = 5,773) in the Chinati Mountains in August 2024. We estimated monthly space use patterns of both species using dynamic Brownian bridge movement models and compared space use pre- and post-aoudad removal. Aoudad ranges were larger (𝑥̅±SD; 5.99±3.50 km2, 5.62±3.64 km2) than mule deer (2.74±2.14 km2, 2.67±2.16 km2) in the Quitman and Chinati Mountains, respectively. In the Chinati Mountains, aoudad space use was similar pre- and post-aoudad removal (5.63±3.68 km2, 5.5±3.17 km2). However, range size shrank following aoudad removal from 2.77±2.19 km2 to 1.78±1.63 km2. Results suggest these two species have differential responses to the lethal removal of aoudad. Additionally, range stability among aoudad suggests population management may not negatively impact aoudad hunting but does not shift remaining aoudad from desert bighorn habitat. This may reduce competitive effects on desert bighorn, though its effects on disease risks are uncertain.

Title: “Grassland Habitat for Pollinators Under Various Mowing Regimes at Fort Davis National Historic Site”
Natural Sciences
ABSTRACT: Habitat loss and fragmentation are contributing to the global decline of pollinators, and species native to fragile desert ecosystems such as the Chihuahuan Desert are especially susceptible to these changes. Pollinators require structural heterogeneity for shelter, native flowering plants for pollen and nectar, and specific host plants for egg laying and larval rearing. Mowing, which removes floral resources and reduces structural diversity, is a management practice used to improve safety and visibility in areas of interest for tourism. Deferred or reduced mowing, however, can benefit pollinators and other insects. Managers at the Fort Davis National Historic Site are interested in balancing tourism goals with natural resource conservation through mowing regimes. Four treatment areas have been implemented at the site: (1) deferred mowing, (2) mowed regularly during monsoon season and as needed, (3) mowed once in the fall, and (4) deferred mowing with prescribed fire and mechanical brush removal. Our study objective is to quantify the impacts of the various mowing regimes on grassland vegetation and pollinator communities. We evaluated plant and insect pollinators at 75 plots across the four treatments in the summers of 2023 and 2024. To survey bees and beetles, we used bee bowl traps placed at the center of each plot and collected them after a 24-hour period. We caught caterpillars using sweep nets, and, to measure butterfly density, we used remote cameras programmed to take 10-second videos twice an hour. To determine how insect community composition varies among treatments, we will analyze data using principal coordinates analysis.

Title: “Preliminary Results: Police Cadets Perceptions of Ethical Boundraries in Hypothetical Misconduct Cases’”
Criminal Justice
ABSTRACT: This research project explores police officers’ perceptions of ethical boundaries through a quantitative approach utilizing a scenario-based survey methodology. The study will present participants with ten hypothetical scenarios involving ethically ambiguous policing behaviors and analyze responses to determine whether perceptions of ethical acceptability differ by race, age group, or ethnicity. Drawing on validated instruments such as the Klockars Integrity Questionnaire, this study aims to assess normative inclinations to resist misconduct across demographic lines. The use of scenario-based surveys has proven effective in minimizing response bias and enhancing the validity of findings in police ethics research (Kutnjak Ivković, Haberfeld, & Peacock, 2012). Further, the robustness and cross-cultural adaptability of the Klockars framework support its application in diverse populations (Alain, Rousseau, & Carrer, 2018). Finally, Maskály et al. (2020) confirm the methodological soundness of this approach by demonstrating the criterion validity of integrity measures in comparative contexts. The findings of this project will contribute to a deeper understanding of how individual characteristics may influence ethical decision-making in law enforcement and inform the development of more targeted ethics training programs.

Title: “Effects of Collective Memory on “La Marcha” of 1966 and the 3 Women Who Lived It”
History
ABSTRACT: I begin my presentation with the histography of the United States and how those attitudes and cultures are entrenched in our current curriculum and also our current cultures. These attitudes and cultures thus create the environment that hispanics were subjected to. From this viewpoint, I have three first-hand accounts from three brave women who lived this time period in history and show a much darker version of our past.

Title: “Photovoice Investigation on the Sources of Failure Amongst High-Achieving Latina Undergraduate Students“
Psychology
ABSTRACT: Some students fear failure to such an extent that it impedes completion of their degree (Nyikos, 2020). Stuart (2013) found that first generation female ethnic minority undergraduates in their first year develop fear of failure from shame and an overwhelming uncertainty of their future. Difficulties observed amongst the Hispanic population include trouble balancing the importance of family expectations and their education (Alva, 1991; Crisp et al., 2015). Limited studies utilizing Photovoice can help provide students with an outlet to examine their perspective of conflicts and bring attention to the mental health stressors (O’Malley & Munsell, 2020). This study used Photovoice to analyze images captured by participants that defined their fear of failure as they attempted to obtain their degrees. My hypothesis was that Latina’s are afraid of failure due to constituents such as family expectations, financial concerns, academia, and lack of mentorship. My second hypothesis was that students were struggling with fear of failure, while balancing their personal and academic lives. Preliminary interview findings revealed that participants struggled with uncertainty when faced with opposition during difficult situations; they struggled to deal with balancing the invisible stressors in their life revealing that they need more guidance and support in their endeavors. On the other hand, survey results revealed that as college students’ fear of failure increases, their ability to cope with stressful life situations diminishes.

Title: Exploring Mycorrhizal Dynamics: A Comparative Analysis of Rotational v. Continuous Grazing Systems”
ANRS
ABSTRACT: Desert ecosystems play a vital role in supporting ranching by providing essential ecosystem services despite how fragile they are. In regions where ranching, grazing, and wildlife management is viable, understanding how land management practices affect the ecosystem is essential. Desert grasslands, particularly those dominated by blue grama (Bouteloua gracilis), are vulnerable to degradation. Management practices can significantly influence plant communities and overall ecosystem health. Different grazing systems were developed to improve ecosystem health and productivity, though their effectiveness is a topic of debate. Blue grama helps maintain productivity in ranching operations as its health closely relates to underground processes, such as the symbiotic relationship with arbuscular mycorrhizal fungi (AMF). AMF enhances water and nutrient uptake and supports plant resilience. This study examines how different grazing systems – continuous and rotational – affect AMF communities in blue grama across two distinct soil types – Marfa and Musquiz clay loams. To assess these differences, mycorrhizal colonization was evaluated using the magnified gridline intersection method after staining roots. Statistical analyses, including ANOVA, were conducted to evaluate mycorrhizal colonization across plots with continuous and rotational grazing on Marfa and Musquiz clay loams. Rotational grazing resulted in higher mycorrhizal colonization compared to continuous grazing, suggesting that rotational grazing creates more favorable conditions for mycorrhizal fungi. For landowners and ranchers in the Chihuahuan Desert, this study emphasizes the importance of adopting sustainable land management practices that support the health of mycorrhizal communities. By prioritizing rotational grazing, ranchers can reduce soil compaction, maintain vegetation cover, and in turn support the symbiotic relationship between plants and mycorrhizal fungi.

Title: “Equine Industry Professionals Attitudinal Differences Toward Horse Gender”
Animal Science
ABSTRACT: In the Equine industry, from ranch horses to Olympic-competition horses, the animals have traditionally been selected for purpose based on animal gender. Except in very specific cases, females (mares) and castrated males (geldings) are much more commonly used than intact males (stallions). There has been limited research focused on the reasons behind those selections. The purpose of this research is to assess the perceptions of equine industry professionals in the United States in relation to the selection of horses based on breed, gender, and use. This project is the U.S. iteration of a multinational project that includes Australia and Brazil. The researcher will use a descriptive methodology with a QualtricsTM-based survey instrument. The population frame includes individuals across all sectors of the equine industry. Convenience sampling will be used. Links to the data collection instrument will be sent out via email to numerous university equine programs, veterinary clinics, and equine associations within the U.S. Respondents will be tasked with a scenario where they must allocate four hypothetical riders with differing genders and ages to three hypothetical horses of the same age and training level. Subjects will also be asked a series of questions to assess preconceived stereotypical bias towards horses based on gender of the animal. Additionally, selected demographic data will be collected from respondents in order to determine differences in attitudes and perceptions across different segments of the equine industry. The data will be categorized and analyzed using descriptive analysis, linear regression, and binomial generalized linear models.

Title: “From Father-Daughter Bonds to Coach-Athlete Dynamics: Exploring Female Athletes’ Interpersonal and Intrapersonal Relationship Connections”
Faculty Nominator: Dr. Alicia Trotman
Psychology
ABSTRACT: This research will broaden the growing research on father-daughter attachment styles/relationships, while also addressing how father-daughter attachment styles/relationships affect a daughter-athlete (Prewitt-White, et. al., 2016). Since the father is the first male in a daughter’s life, this relationship/attachment is crucial for understanding how female athletes create later interpersonal relationships with males in their lives. Athletes require compatibility with their coaches to identify a secure relationship (Jowett, etc. 2003). These relationships are both intrapersonal and interpersonal, which is how the relationship is viewed by both parties (interpersonal) and how the relationship is viewed by an individual (intrapersonal) (Jowett, etc. 2003). For female athletes, this includes how they navigate their interpersonal relationships with their male coaches and handle their intrapersonal disposition in terms of how they see themselves as athletes. Within this study, the research will explore if a collegiate level female athlete’s relationship/attachment to their father mirrors the relationship/attachment the female athlete has created with their male coaches in terms of three factors of secure attachment (degree of closeness, level of commitment, self-image). This research will add to the minimal bracket of research done on rural NCAA Division II female athletes.

Title: “Mitigating the Effects of Temperature Extremes to Aid Native Seed Germinatio”
Faculty Nominator:
Rangeland Management
ABSTRACT: A growing restoration practice for degraded rangelands is the application of native seeding. However, germination and survival of seedlings are highly variable with low success. Soil temperature is a primary factor influencing successful germination of seeds. Native seeding in the Chihuahuan Desert is subject to highly stochastic annual temperatures. Thus, it is important to find ways to maintain optimal temperatures for seed germination and survival. We utilized combinations of brush limbs and erosion-control straw blankets on a degraded site in south Brewster County, Texas. Temperature readings, taken every 30 minutes, were collected from July 27th of 2024 to March 1st of 2025 with HOBO soil temperature loggers. HOBO Loggers were buried within the top 12 cm of soil underneath treatments. Data showed that the combination of straw blankets and brush reduced temperatures overall during summer months and held temperatures constantly warmer during winter months. Data showcased that all treatments implemented had a substantial effect on maximum daily temperatures while having minimal effects on minimum daily temperatures. This study provides evidence that restoration practices such as these can potentially aid plant germination success by keeping seeds in more optimal temperatures.

Title: “Texas Tortoise’s Movement Patterns Across the Chaparral WMA”
Faculty Nominator:
Wildlife Management
ABSTRACT: Texas tortoise (Gopherus berlandieri) is found across portions of South Texas and Mexico, with a part of the population being found on the Chaparral Wildlife Management Area (WMA). This population has been systematically studied for over a decade, providing species indicators and trends. This study examines how habitat is utilized and how the Texas tortoise movement trends fluctuate from month to month. Over a 14-year period employees of the Chaparral WMA performed opportunistic captures of Texas tortoise, and recorded weight and length measurements, captured location information, and marked the shell with a unique identification code. This data was then analyzed in excel functions. It was found sex ratios were fairly even across the property, and tortoises were most active between April and October. During these months, tortoises experienced increased length and mass growth due to forage availability. Habitat preference correlated with moderately rocky soils and greater spacing between vegetation types (specifically less dense brush). Site fidelity was observed in a majority of recaptures, with females having a higher tendency to remain in a small area. The northwest portion of the Chaparral WMA was more heavily utilized than other portions due to meeting more of the observed habitat preference markers. While the data collected in this study is beneficial, more research is needed to truly understand how Texas tortoise utilizes its habitat. In future studies, it would be beneficial to collect temperature, precipitation, and any foraging behavior observed.

Title: “From Childhood to College: Coping with Parental Mental Illness and Attachment Challenges in a Rural Setting”
Faculty Nominator: Dr. Alicia Trotman
Psychology
ABSTRACT: Exploring the relationship between parents with Severe Mental Illness (SMI) and their children is important because many participants of Murphy et al. (2011) reported that the difficult and confusing relationship with their parents with SMI had powerful effects on their emotional distress and development. As noted before, Metz and Jungbauer (2021) highlighted that their participants often felt a strong sense of responsibility for the wellbeing of their parents, causing emotional exhaustion and even difficulties in setting boundaries. The objective of this study is to use a lived experience-based design to determine how children with SMI cope with their experiences and manage their close relationships. By employing a narrative inquiry through interviews, a lived experience-based design can be used to establish an authentic understanding of adult children in college who have experienced parental mental illness (Metz and Jungbauer 2021). This study expands previous research by using a narrative inquiry approach, focusing on an underrepresented population and highlighting strategies for resilience that may be instrumental in breaking the intergenerational cycle of mental illness. Specifically, the study aims to identify coping strategies, capture personal narratives, contribute to existing literature, and support strategies that may help mental health professionals, educators, and policymakers. My research question is: How do adult children with parental mental illness in a rural college cope with their experience, and manage their close relationships?

Title: “Livestock Tank Forage and Cover for Migratory and Wintering Grassland Birds in the Trans-Pecos”
Faculty Nominator:
Wildlife Management
ABSTRACT: Overwintering bird species in the Chihuahuan Desert grasslands have been undergoing population declines due to various forms of habitat degradation. Livestock tanks in the region could increase the odds of survival for birds by providing a source of food and water in an otherwise resource-limited region. Even when dry, tanks contain plant life that is unique from the typical grassland plant species surrounding them, offering a diverse location that acts as an attractant to overwintering birds. This study will identify the plants found in livestock tanks and outline their importance in terms of foraging value and cover to overwintering birds through Chihuahuan Desert grasslands. Methods include quarter meter squared quadrat sampling of vegetation seed production, line intercept methods to outline brush coverage, and a seed bank inventory from each tank. Collecting forage value inside and outside the tanks as well as cover percentages may assist in making management decisions for both wintering birds and livestock.

Title: “I’m Only Human: Investigating the Challenges that Female D2 College Athletes Undergo on Seeking Mental Health Services”
Faculty Nominator: Dr. Alicia Trotman
Psychology
ABSTRACT: Collegiate athletes face numerous challenges throughout their careers. According to Hilliard, Watson, and Zizzi (2022), these athletes experience intense demands due to their rigorous schedules, with the pressure to succeed both academically and athletically increasing the need for mental health services. However, research indicates that self-stigma and public stigma are significant barriers preventing athletes from seeking these services. Beyond stigma, other factors such as help-seeking behaviors, attitudes, and mental health literacy also influence their willingness to seek support. This study aims to explore why female collegiate athletes do not seek mental health services by examining three key variables: their knowledge of mental health, their help-seeking behaviors, and their attitudes toward seeking help. The research question guiding this study is: How do athletes’ mental health literacy, help-seeking behaviors, and attitudes toward seeking help influence their willingness to access mental health resources? The hypothesis suggests that female collegiate athletes with more open attitudes toward seeking help and higher mental health literacy are more likely to utilize mental health services.

Title: “Learning Law, Learning Bias? Implicit Associations Among Criminal Justice Majors”
Faculty Nominator: Dr. Alicia Trotman
Psychology
ABSTRACT: The criminal justice system deals with high-stakes decisions every day that can change a person’s life. These decisions can derail an individual, therefore changing their life forever and affecting their well-being (Pierce et al., 2023). These quick judgments can easily be influenced by many variables and factors surrounding things such as the situation or certain biases (Amodio, 2014). One significant bias is implicit bias, which refers to the unconscious attitudes or stereotypes that affect our understanding, actions, and decisions (Amodio, 2014). The objective of this study is to examine whether criminal justice education influences implicit bias among Latino/a students, specifically comparing criminal justice majors with students from other fields of study. The aims are to explore if criminal justice education reinforces or reduces implicit bias and to investigate if in-group bias exists within Latino/a criminal justice students. Additionally, the study seeks to provide insights for improving educational programs and reducing bias in the criminal justice system.

Title: ’Big 12 Collectives & How They Have Affected the Transfer Portal”
Faculty Nominator: Dr. Jessica velasco
Political Science
ABSTRACT: In 2021, after the NCAA v. Alston Supreme Court decision, states and universities were left to figure out how best to manage Name, Image, and Likeness (NIL). Those who pay attention to the world of collegiate athletics have been nervous and curious about how these changes would impact collegiate athletics. Studies are just starting to emerge, although assessing the impact of NIL policies is difficult due to the patchwork of policies and laws across the country. One largely unknown component of the NIL space is the collective. This study seeks to shed some light on collectives, their history, their role, and the relationship of these collectives to other variables and changes in the collegiate athletics space. To make the study scope manageable, the focus will be on the BIg 12 schools, which contain both public and private institutions from several states, including those with and without NIL laws. This will allow for a comparison of the relationship of the collectives to a number of school and state variables.

Title:“Investigating the Integration of Humanistic Ideals and Christianity on Performance and Personal Excellence for Collegiate Athletes”
Faculty Nominator: Dr. Alicia Trotman
Psychology
ABSTRACT: This study examines the role of Christianity in performance and personal excellence, focusing on collegiate athletes at a Division II rural institution. It builds upon the foundational models of Dodgen and McMinn (1993), Egli & Hoven (2020), and Mosl ey et al. (2013), using an integrated framework to understand how Christian athletes resolve their tensions with their faith with humanistic principles. While these athletes may not consciously recognize their use of such principles, their experiences may reveal an internal religiosity that complements their external religious expressions in relation to academic and personal excellence. A mixed-method approach will be utilized, incorporating quantitative measures (Intrinsic Religiosity Subscale, Duke Religion Index, Religious Life and Orientation Scale) and qualitatively guided interviews. I will explore the depth of internal and external religiosity that exemplifies their personal growth that is not only based in their faith but expressed using humanistic concepts like self-actualization. If this integration is present, I anticipate that Christian athletes will demonstrate a consistent commitment across their identities as athletes, students, and Christians, experiencing minimal tension between these roles. The balance of intrinsic and extrinsic religiosity may further illustrate how humanistic principles support their faith in fostering personal growth—both on the field and in the classroom.

Title: “Vertebrate Paleontology Methods in the Laboratory and Field: A Title III Internship”
Faculty Nominator:
Paleontology
ABSTRACT: The primary goal of my paleontology internship is to gain practical experience in various aspects of paleontological lab and field work. During my internship through Title III, I have assisted in preparing two significant dinosaur specimens: a large hadrosaurid from the Aguja Formation (Campanian) and material from a sauropod from the Javelina Formation (Maastrichtian). In the paleontology lab, I have gained experience in fine-scale fossil preparation, using a pneumatic air scribe, Dremel tool, and hand tools to effectively remove surrounding matrix from vertebrate fossils. In the field, I have learned how to properly apply jackets to large fossils using burlap and plaster to protect them during excavation and transport. I have also learned several techniques for fossil prospecting, including bulk screening in the field and traditional prospecting methods. Working with fossils in the lab and field have greatly improved my ability to identify vertebrate fossil bones. The hands-on experience facilitated by the Title III internship has provided me with a better understanding of fossil excavation and preparation in the field of paleontology.

Title: “What Happens When College Feels Like Chaos? Stress and Coping in Students with BPD Symptoms”
Faculty Nominator: Dr. Alicia Trotman
Psychology
ABSTRACT: Students with Borderline Personality Disorder (BPD) often struggle with emotional instability, impulsivity, and relationship challenges, which can create significant obstacles in managing academic stress and university life responsibilities. Despite being part of a larger student population, those experiencing BPD symptoms frequently find college stress overwhelming. While some students receive formal diagnoses and mental health care, many do not. Additionally, those with BPD symptoms may be unaware of their condition due to stigma, discrimination, and limited access to mental health services. Research by DiBenedetti et al. (2023) and Lamba et al. (2024) highlights the misunderstanding and lack of support that students with BPD symptoms face. Given these challenges, qualitative research focusing on students with BPD is essential to better understand their experiences and address their unique needs. My research study investigates these experiences and stress management of college students who exhibit symptoms of Borderline Personality Disorder (BPD). Current knowledge about BPD stems mainly from clinical environments but with this research I hope to investigate how students with emotional dysregulation try to succeed in college. This research will gather direct insights from students about their difficulties and their methods of coping through personal interviews that I will be conducting. The research will address a knowledge deficiency in current studies, and I hope to provide valuable information to develop improved support services for college students.

Title: “Leafing Stress Behind: A Root-iful Journey into Indoor Plant Therapy”
Faculty Nominator: Dr. Alicia Trotman
Psychology
ABSTRACT: Modern sedentary lifestyles and disconnection from nature have raised concerns about mental and physical health (Hassan & Deshun, 2023). This research investigates the impact of indoor plants on young adults’ mental well-being in classrooms. Many studies have examined the influence of plants on student learning and well-being, but few have focused on higher education (Bogerd et al., 2020; Daly et al., 2010). College students may experience attention difficulties in classes due to high expectations, test pressure, coursework, and other school activities (Bogerd et al., 2020). The stress associated with college demands can negatively affect students’ future outlooks and their ability to focus and learn. To improve the classroom environment and support student well-being, integrating nature into learning spaces is important. This study explores the potential benefits of indoor plants on health, attention, and perceived classroom environment. Using a quasi-experimental design, it compares two college classrooms within the same subject to evaluate these effects. Most findings will be analyzed and presented by the symposium date.

Title:“Fostering Community Engagement Through Service Learning: Interdisciplinary Perspectives on a Low-Cost, High Yield Student Project”
Faculty Nominator: Dr. Alicia Trotman
Psychology
ABSTRACT: Our study looks at a community service project where a group of college students studying psychology delivered elementary student-designed Valentine’s Day cards to residents of a nursing home. The project was intended as an example to encourage community service among college students. In retrospect, it was seen to be a success as an activity. Upon further evaluation, it was also seen to be an example of service learning that required a minimal investment of time and resources while benefiting three groups and three institutions, thus making it an exemplary model of a low-cost, high-yield service initiative. With an interdisciplinary approach, we explore the project from organizational and psychological perspectives. Organizationally, the project had efficient resource allocation and involved cross-institutional collaboration. From a positive psychology standpoint, the project aligned with research on well-being, gratitude, and social connectedness, benefiting all three participating groups. From a personality psychology standpoint, the project offered a chance to gain insights into traits associated with volunteerism, such as empathy and extraversion. Our analysis emphasizes the implications of designing and conducting small-scale service programs in educational settings, demonstrating how they can enhance student development and produce social capital. This paper contributes to discussions on experiential learning, service-based learning, and institutional partnerships. It provides a framework for replicating similar projects in higher education settings.

Title: “How Does Physical Activity Impact Older Adults in Reducing Fall Rates and Facilitating Faster Recovery”
ABSTRACT: As individuals age, they often experience a decline in muscle mass and strength, leading to mobility limitations. This can increase the risk of falls, which in turn may compromise functional independence and elevate mortality rates among older adults. To address these issues, we can do a well-structured physical activity plan which is essential for reducing fall risk and improving overall health. A 2020 study done by The International Journal of Behavioral Nutrition states that 30-50% decrease in the frequency of fall compared to sedentary participants. [2] Furthermore, older adults who maintain regular physical activity report quicker recovery times than those who are inactive. [1] To create an effective plan, the first key component implemented is aerobic exercise as it targets larger muscle groups and improves cardiovascular health. Activities like walking, cycling or swimming can promote endurance and support mobility. Second, functional training plays a crucial role in maintaining strength. This type of strength training focuses on movements that mimic daily tasks. Finally, balance exercises help strengthen stabilizing muscles and improve coordination, directly reducing the risk of falls.

Title: “Examining the Complex Relationship Between Sleep, Health, and Academic Performance in College Students”
Kinesiology
ABSTRACT: College students often face various challenges, including academic pressures, social transitions, and lifestyle changes that can impact their well-being and overall success. This research project investigates the complex interplay between sleep, health, and student success within a diverse college student population. Utilizing a cross-sectional study design, this research will employ validated questionnaires to assess multiple dimensions of sleep, including factors such as sleep duration and sleep quality, alongside health behaviors like physical activity and sedentary behavior, as well as psychosocial factors like stress, anxiety, and social support. Participants will also self-administer standardized health assessments to measure physiological health status, such as estimated cardiorespiratory fitness and heart rate variability measurements, to gain insights into their autonomic nervous system functioning. Student success will be evaluated through objective metrics such as GPA, satisfaction, and involvement in extracurricular activities. Results will provide descriptive characteristics of the student sample, including prevalence of sleep disorders, depression, and anxiety, as well as allow for the association among these variables on health and measures of student success. Understanding the dynamic relationships among these variables is critically important, as sleep disturbances and health issues can affect students from various backgrounds. This study aims to underscore the importance of holistic student well-being, highlighting how supportive interventions that foster healthier sleep habits can lead to improved student success. By focusing on the entire college demographic, the research seeks to inform educators and policymakers about the necessity for targeted support systems that can enhance overall student health and success.

Title: “Structural Analysis of Boquillas Canyon Fault, Big Bend National Park, Texas”
Business
ABSTRACT: The Boquillas Canyon Fault in Big Bend National Park records a complex history of deformation influenced by both Laramide contraction and subsequent Basin and Range extension. Located along the Rio Grande, this fault system provides an opportunity to investigate fault reactivation and the evolution of regional stress regimes. This study will integrate remote sensing with field-based structural analysis to refine the fault’s tectonic history. Measurements of bedding planes and slickenline orientations on exposed fault surfaces, combined with a lineament analysis of fault and fracture trends using ArcGIS, will help determine whether oblique deformation occurred during one or both of the recorded tectonic events. The presence of overprinted structural fabrics may also indicate reactivation along preexisting crustal weaknesses that could extend as far back as Precambrian tectonic events. By combining field observations with GIS-based structural analysis, this research aims to clarify the kinematics of the Boquillas Canyon Fault and its role in the region’s broader deformational history. Understanding how this fault accommodated strain over time will not only refine interpretations of tectonic processes in Big Bend but also provide insights into subsurface fault geometry. These structural controls have implications for groundwater flow and storage, making this study relevant for both tectonic reconstructions and hydrogeologic assessments in the region.

Title: “Outcompeting the Invader: Enhancing Native Species In Lehmann’s Lovegrass (Eragrostis lehmanniana) Dominating Rangelands”
ANRS
ABSTRACT: Non-native species like Lehmann lovegrass (Eragrostis lehmanniana) were introduced to the USA for erosion control and forage for cattle due to their resistance to drought, fire, and pests, making them highly adaptable to new environments. However, invasive plant species have a high capacity to spread and create monocultures, outcompeting native plant species (NPS) and reducing biodiversity, negatively impacting wildlife. This study aims to restore NPS and control Lehmann lovegrass in the Chihuahuan Desert. Research was conducted on Nine Point Mesa Ranch, Brewster County, Texas, across 200 plots, using treatments: seeding (S), soil disturbance (SD), and a combination of them (SDS), plus controls (C). Data were collected over 2 years (2022-2024) using line intercept transects to measure vegetation cover. Results indicate that controls had more bare soil presence, and litter increased across treatments by winter 2023 and 2024. Plant diversity improved with S and SDS versus controls. Lehmann lovegrass is the second most abundant of 23 introduced species at the site. The Redundancy analysis evaluated treatment effectiveness to achieve the project goal, showing relationships between treatments and species. In fall-2022 and winter 2022 and 2023, the relationships were positive for NPS and negative for Lehmann lovegrass across treatments while controls had more presence of the invader. In fall-2023, NPS and ERLE show a positive relationship with S and SDS, and the invasive keep its positive response with controls. In winter 2023 and 2024, Lehmann lovegrass shows positive response on controls and better response to SD, while NPS present positive relationships with S and SDS. Overall, S and SDS allow NPS to have a balanced competition with the invader, even if this has persistent invasive behavior.

Title: “Using Satellite Imagery to Estimate Carrying Capacity of Bighorn sheep on Elephant Mountain Wildlife Management Area”
ANRS
ABSTRACT: Elephant Mountain Wildlife Management Area (EMWMA) is the nursery population for ongoing desert bighorn (Ovis canadensis) restoration efforts in Texas. Consequently, the primary management objective is production of surplus animals for translocation. However, EMWMA also provides public hunting opportunities, particularly for mule deer (Odocoileus hemionus). Thus, maintaining a healthy mule deer population is also a key management goal. Estimating EMWMA’s carrying capacity of bighorn is essential to mitigate competition between bighorn and mule deer, as well as preserve habitat quality. Traditional methods of estimating carrying capacity are time-consuming, imprecise, and costly. Due to these constraints, assessments occur infrequently. However, carrying capacity is not constant through time, as environmental conditions vary from year to year, causing dramatic shifts in habitat quality. To keep pace with these shifts, biologists require an efficient method of assessing habitat quality and carrying capacity on an annual basis. Our objective is to leverage satellite imagery to monitor desert bighorn nutrition on EMWMA. Previous studies established a relationship between satellite vegetation indices and bighorn nutritional performance, but we expect this relationship to be density dependent, allowing us to estimate carrying capacity remotely. Because increased density reduces per capita resource availability, we hypothesize interspecific competition makes the slope of the relationship between vegetation greenness indices and fecal nitrogen inversely related to desert bighorn abundance. If this is the case, this density dependence can be leveraged to provide a framework for efficient monitoring of desert bighorn carrying capacity via satellite, providing managers essential information at little to no cost.

Title: “Comparing Presence/Absence Methods For Detecting Montezuma Quail“
ANRS
ABSTRACT: Montezuma quail (Cyrtonyx montezumae) are one of the most understudied gamebird species in North America. They can be found mainly in Mexico but also in certain areas of Arizona, New Mexico, and the Edwards Plateau and Trans-Pecos regions of Texas. Their unique coloration and behavior of crouching or flushing at the last second makes them difficult to study. We assessed 2 different presence/absence survey methods to determine which has a greater detection rate. The first method was the use of autonomous recording units (ARUs) to obtain acoustic recordings. The second method was visual detection of digs. The study was conducted on the Davis Mountains Preserve in Jeff Davis County. We randomly selected locations to place 20 ARUs during the breeding season. Each ARU recorded every day at 10 minute per hour intervals for 3 hours beginning at sunrise. We walked spiral patterns within a 200m-diameter circle around each ARU and documented dig presence. We used BirdNET to analyze ARU data that was recorded 3 days prior to each dig survey. Out of the 20 ARUs, we checked 16 of them twice and 4 of them once. There were a total of 22 detections, 8 of which had only vocalizations, 9 had only digs, and 5 had both detection methods. Using the Jaccard index statistic, we calculated a 0.227 similarity between vocalization and dig presence. Therefore, combining both methods is the best approach for evaluating the presence of Montezuma quail.

Title: “Foundation of Small Business”
Business
ABSTRACT: This fellowship project, “Foundations of Small Business,” builds upon my prior academic presentation on the definition and importance of small business in today’s economic and social landscape. Targeted toward a collegiate audience of scholars and educators, this initiative seeks to explore and present an applied, research-driven framework for guiding individuals through the process of starting and sustaining a small business. Rooted in both academic theory and real-world application, the project outlines key steps in launching a small business, including identifying market needs, developing a business plan, navigating legal and regulatory requirements, securing funding, and applying digital marketing strategies. By emphasizing the role of small businesses as engines of innovation, local job creation, and community resilience, the project invites academic discussion around entrepreneurship as a practical tool for economic empowerment—particularly for underrepresented or first-generation entrepreneurs.
Through the development of educational materials, case study analysis, and interactive modules, this project aims to foster a deeper understanding of small business formation among students and faculty, alike. The ultimate goal is to create a transferable, interdisciplinary model that can be integrated into college-level curricula and outreach programs. This fellowship will provide the foundation for future academic engagement, curriculum development, and potential research collaborations focused on entrepreneurship education. By blending scholarly insight with practical guidance, this project reinforces the vital connection between academic institutions and the communities they serve through entrepreneurial development.

Title: “Explaining the Relationship Between Elevation and Gut Microbiome Diversity of the Crevice Spiny Lizard (Sceloporus poinsettii) in The Christmas and Davis Mountains“
Biology
ABSTRACT: I will be investigating the effects between populations on gut microbe diversity of Sceloporus poinsettii, between the Christmas Mountains (~914m to 1,737m) and the Davis Mountains (~1,524m to 2,560m) of West Texas. The Davis Mountains are commonly referred to as a “Sky Island” ―a mountain range surrounded by West Texas desert. Its cool temperatures and moderate rainfall make it an ideal habitat for a range of species. However, the Christmas Mountains are arid, hot, and, though they receive almost as much rainfall as the Davis Mountains, evapotranspiration is much higher. The objectives of this project are (1) to analyze gut-bacteria of S. poinsetii in different habitat types, (2) to observe whether diet, habitat or both influence gut-microbial diversity, and (3) further identifying their key habitat features to better understand optimum habitat conditions. Diet has been looked at in some populations of S. poinsettii, but the microbial diversity based on diet and habitat are poorly understood. By analyzing gut microbiota, I hope to gather insight on how S. poinsettii persists in varying conditions. In this study, I will amplify the V4 region of the 16s rRNA bacterial gene via 16s amplicon sequencing. This will help identify highly conserved segments of bacterial DNA and will be compared with existing databases to help identify said bacteria. I expect to see significant differences in gut microbial composition as a result of habitat differences. This research will assist future studies to better understand how gut microbiota is affected by West Texas ecosystems.

Title: “La Catedral: A Brief Explanation of a Guitar Masterwork“
Music
ABSTRACT: Agustín Barrios Mangoré (1885-1944), the world-renowned guitarist and composer from Paraguay, rose to prominence in the early 20th century among notable contemporaries such as Emilio Pujol (1886-1980) and the famous Andres Segovia (1893-1987), both Spanish-born. Barrios’ immaculate technical abilities and keen compositional taste, teetering between nationalistic folk dances and modern impressionistic nocturnes, displayed his invaluable contribution to the classical guitar. La Catedral, widely considered one of his crowning achievements, was written circa 1914. Andante Religioso and Allegro Solemne, the second and third movements respectively, were inspired by the juxtaposition of the Cathedral of San Jose and the city of Montevideo, Uruguay. The slow and introspective second movement mirrors the processional within the walls of the Catedral as the worshipful priest walks through the sanctuary. Meanwhile, the scene completely changes as we suddenly exit the building and meet the fast-paced, sporadic and lively outside world in the third movement. Later in his life, he composed a prelude for this work – the Preludio Saudade – in 1938,to commemorate his wife Gloria. In present-day performances of this masterwork, the three movements are played together. This talk will aim to highlight the intentions of Barrios in his compositional choices whilst also marrying analytic interpretation with performance. The presentation will end with a full performance of the work, followed by a short Q&A. The presentation will be filmed.

Title: “Architectural Design and Home Planning”
Architectural/Interior Design
ABSTRACT: In this presentation, I will share my experience as a non-traditional student in a home design course highlighting the blend of excitement and anxiety that I felt as I navigated a technologically advanced learning environment. Leveraging employee benefits at Sul Ross, I seized the opportunity to take courses, thus reigniting my passion for home design and industrial technology after years away from academia. The architectural drafting and home planning course taught by Professor Carolyn Barrientes was particularly fulfilling as it allowed me to visualize my ideas through the Chief Architect software drafting program. The purpose of this final exam was to remodel an entire home. This experience not only brought my vision to life, but also offered an enlightening perspective on the design process.

Title: “From Textbook to the Workforce: Architecture and Construction at Sul Ross”
Architectural/Interior Design
ABSTRACT: In this presentation, I aim to explore my semester-long journey at Sul Ross as an industrial technology major. After I graduate, I plan to work as a construction manager and help people build their dream houses. Last semester, I studied under Carolyn Barrientes in a class called Architectural Drafting and Home Planning. Our final project for the semester was to build a house in a drafting software called Chief Architect. We were to come up with a “client profile,” which was a description of who our client was and what they would need out of the house we were designing. Using the Chief Architect software was very engaging. There were tons of decisions and applications to learn. This project was very fulfilling because I got to see what being a designer feels like, from start to finish. The stages of the project from speaking with the client for the first time to presenting the fulfilled design, and potentially to have a bank approve a loan, were a great experience.
Additionally, I am also a part of the Title III internship grant program and would very briefly like to speak about my experience there, as well. Following a company and learning from someone with years of experience has been invaluable. My professors and mentors have each been in my shoes and understand the importance of hands-on experience. I have made documents that can track the status of materials on a job site. I have learned how to “close-out” a house by getting the final touches on a newly built home finished. I have seen remodels and newly built duplexes and been able to say I had a hand in each of them. This program is very important for students who need that extra step outside the classroom and it has taught me amazing skills I can take with me through the rest of my career.
