Stress As A Means Of Success: Investigating The Effect Of Stress Appraisals On Willpower, Ego Depletion, And Physiological Responses In College Students, Anna Minor

Honors College Theses

Stress impacts our emotions, cognition, behavior, and health. Although stress is abundant and unavoidable, recent research suggests our perception of stress can strongly influence its outcomes. The Biopsychosocial Model of Challenge and Threat (BPS) states that we appraise a stressful scenario in one of two ways: challenge or threat. A challenge appraisal involves a positive perception of stress and is associated with lower physiological output while a threat appraisal involves a negative perception of stress and increased physiological arousal. The current research seeks to apply the BPS to a cognitive task and consider its relation to willpower, ego depletion, and …

Predicting Capture And Survival Probabilities Of The Arizona Tiger Salamander: A Comparison Of Capture-Recapture Models, Brittney Nelson

Murray State Theses and Dissertations

Capture-recapture models are essential tools for estimating population dynamics in ecological studies. A fundamental component of these models is the capture history matrix, which records individual detection over time and serves as the basis for estimating survival and capture probabilities. This presentation explores three statistical approaches to these estimations: the Cormack-Jolly-Seber (CJS) model, the Hidden Markov Model (HMM) for CJS, and the Bayesian CJS model. The CJS model provides a likelihood-based framework for estimation, and the HMM CJS incorporates latent states into the model to account for uncertainty in detection. The Bayesian CJS extends this same analysis by integrating prior …

Equine Hair Cortisol Concentration And The Effects Of Season, Storage Method, And Personality Traits, Savannah M. Rivers, Grace A. Robertson, Thomas Powell, Lydia O'Sullivan, Shea Porr

Murray State Theses and Dissertations

Stress exists everywhere, for survival, adaptation is necessary. These adaptations directly reflected the stresses the animal experienced and demonstrated the ability to cope. An animal that could not cope could not survive. Stressful experiences resulted in behavior patterns for each animal. Consistent behavior can be defined as personality [1]; therefore, stress could directly influence personality by changing behavior.

Stress research helped analyze and identify animal personality traits, especially horses. Human-horse pairings partially relied on personality traits and, when considered, often led to improvements in welfare [2]. There are various tools to assess personality, one being Equine Personality Assessment [3]. The …

Out Of The Circle: Exploring Religious Ostracism In Cyberball, Ralph D. Stewart Iii

Murray State Theses and Dissertations

The purpose of this study was to investigate the psychological effects of social ostracism in group settings, particularly in relation to social identity theory (Tajfel & Turner, 1979) and the need to belong (Baumeister & Leary, 1995). Collective self-esteem, hostility, and belonging were examined to see if they changed significantly with the implementation of ostracism through the Cyberball paradigm (Williams, 2000). The relationship between ostracism, hostility, and religious fundamentalism was also explored. Though insignificant results from subsequent analysis were obtained, these results suggest weaker ostracism effects for interpersonal measures rather than intrapersonal measures consistent with findings by Hartgerink et al. …

Analyzing The Impact Of Geographic Location, Owner Knowledge, And Veterinary Guidance On Equine Vaccination Protocols, Colleen Mcanally

Murray State Theses and Dissertations

This study explored how equine owners decide which diseases their horses are vaccinated for based on their geographic location, the knowledge they have on specific equine diseases, and how much they rely on their veterinarian’s recommendations. A total of 55 horse owners throughout the United States completed an online survey. The results showed that while most owners vaccinate for common core vaccines including West Nile Virus, Tetanus, and Rabies, fewer vaccinated for risk-based vaccines like Leptospirosis. Many owners felt confident in their knowledge of national guidelines for annual core vaccinations, but only a small number of owners were able to …

Bridging Diversity And Discipline: Stakeholder Perceptions Of Dei And Technical Rigor In Agriculture Education, David A. Yarbrough

Murray State Theses and Dissertations

School-based agricultural education (SBAE) serves as a foundational model for preparing students through classroom instruction, Supervised Agricultural Experiences (SAEs), and FFA involvement. This study examined the perceptions of Georgia high school agricultural educators regarding how diversity, equity, and inclusion (DEI) initiatives impact technical rigor and traditional agricultural knowledge within SBAE programs. Educators reported that DEI efforts did not compromise technical rigor, and traditional elements, such as SAE and FFA, remained central to program success. These findings suggest that inclusion and tradition can coexist, with DEI seen as a complement rather than a conflict with SBAE goals. The results provide valuable …

Spatial Analysis Of American Chestnut (Castanea Dentata) Distribution And Ecology In Kentucky’S Federal Lands, Jacob Raymond Pease

Murray State Theses and Dissertations

Anthropogenic factors have been the cause of the decline of tree species across the globe. From unsustainable logging and development to disease and improper management, threats to forests have taken their toll. The American chestnut (Castanea dentata) was once an integral basal tree species in Appalachian forests, but chestnut blight drove the species to functional extinction by the mid-1900s. The recent creation of genetically modified chestnuts gives hope for future restoration of the species throughout its historical range. Despite blight resistance, effective restoration will require optimal site selection for finding and planting chestnuts, which will maximize limited resources. …
