Managing The Mood: How Managerial Communication Shapes The Experience Of Emotional Labor Among Restaurant Employees, Brynn Olverson

Electronic Theses and Dissertations

Restaurant work is emotionally demanding work for servers and bartenders. Organizational Support Theory (Eisenberger et al., 1986) suggests that employees’ perceptions of their organizations’ support can bolster the negative side effects of such work. However, past instruments used to measure these perceptions do not distinguish between types of emotional experience, nor separate perceptions of emotional support from other forms of support. Likewise, OST notes that supervisors play a key role in influencing perceptions of organizational support, but more work is needed to determine specific communicative behaviors that can increase perceptions of organizational support. The study at hand proposes that managers' …

The Fertilization President: A Rhetorical Analysis Of The United States’ Rebirth Of Pronatalism, Kara Vetch

Electronic Theses and Dissertations

The United States experienced one of the lowest birth rates in decades in 2024 and has been blamed by policymakers for poor economic and societal outcomes.

Discovery Of The Multi-Ion Bridge Intermediate: A Computational Exploration Of The Mechanism For Azomethine Ylide Formation From N-Oxides, Martin J. Neal

Electronic Theses and Dissertations

Density functional theory (DFT) provides a method for calculating the ground-state energies of complex molecular systems through evaluating the electron density instead of the full wave function. When results match either experimental outcomes, calculations with DFT offer a computationally efficient method to help explain chemical phenomena. The transformation of tertiary amine N-oxides to azomethine ylides, a simple route to the precursor for 1,3-dipolar cycloadditions that result in the pyrrolidine scaffolds found in natural products, has received only minimal attention due to concerns that its mechanism includes a highly electrophilic intermediate. Utilizing DFT to model the mechanism of the conversion …

(Un)Intended Consequences Of Race In Medicine: The Ethics Of Race-Based Medical Practice And The Perpetuation Of Structural Racism, Allegra Merriweather

Electronic Theses and Dissertations

This dissertation proposes that race-based medicine acts as a form of structural racism that is ethically indefensible. While it may be claimed to be a neutral diagnostic tool, the medical use of race as a biological proxy only further enforces the very hierarchies it purports to remediate, reinscribing inequity from conception to death. Building off Jacques Ellul’s work on Technique, we interpret race-based medicine as a self-perpetuating system that values procedural expediency over moral accountability. In nine chapters, the analysis follows the ways this technique is manifested in genetics and assisted reproduction, where commodified racial selection preserves social hierarchies; in …

Sue Gunter And The Battle For Equity In Women’S Athletics At Sfa, Derek S. Allen

Electronic Theses and Dissertations

From the 1950’s through the 2000’s, women’s college basketball would move from a category of inappropriate activity to selling out large arenas and being broadcast to millions of viewers on national TV. Such a result came largely from federally mandated stipulation contained within Title IX, accelerated a fight for equity and acceptance, and advanced the cause for women’s athletics more than any other initiative. However, that alone would have failed to grow the popularity of a sport such as women’s basketball if it did not produce a quality product for fans. Beyond the need for resources comparable to men’s athletics, …
