Essential and Flexible Expression: Strategies for Pronoun Use among Nonbinary-Identified Individuals

Description: Drawing on in-depth, semistructured interviews with 42 nonbinary-identified individuals in Texas, I examine both the relationship between pronouns and identity and how individuals use pronouns in interaction. Some individuals speak about their pronoun set as a crucial component of their gender identity, adopting what I refer to as an essential expression strategy, while others discuss their pronoun set as more loosely connected to their non-binary identity, adopting what I refer to as a flexibl… more

An Evaluation of Differential Attention on Preferred Topics of Conversation for Adults with Autism Spectrum Disorder

Description: Extensive speech on preferred conversation topics may limit conversations with others. For individuals with ASD, extensive speech on a topic may be a form of restricted or repetitive behavior that may be addressed through skill building. However, previous research suggests that skill building may not be necessary if the behavior is sensitive to differential reinforcement contingencies. To evaluate the effects of differential reinforcement in the form of attention on conversation topics, we repl… more

Exploring the Circularity of Fast Fashion Using Goal Framing Theory

Description: The COVID-19 pandemic has challenged fast fashion to circular products to prevent excessive overstock in responding to consumers' shift toward less consumption. These shifts are worth studying as consumers are willing to partake in pro-environmental behaviors, leading to a circular business model for fast fashion. This study explores how sustainable knowledge and consumer goals toward circularity can influence behavior toward circular consumption based on the goal framing theory. An online sur… more

The Extended Lydian Locrian Theory of Harmony

Description: The extended Lydian Locrian theory of harmony (ELL) is a system of analyzing harmonies and progressions according to their position along a vast spectrum of colors. The musical premise is that chords and progressions spanning upwards around the circle of fifths sound brighter, whereas chords and progressions spanning downwards around the circle of fifths sound darker. This simple premise gives rise to a complex but unified system of harmonic structures and relations, a system which provides a … more

An Extension of a Peer-Mentoring Training Program for College-Aged Students

Description: An important predictor of the success of a peer-mentoring program is the quality of the relationship between the peer mentor and the mentee. A previous study identified target outcomes, operationally defined target behaviors, and developed a computer-based instruction (CBI) training module to teach peer mentors relationship skills. The previous study suggested that the CBI training module increased target behaviors in pre-and post-tests that were typed. The current study replicated and extended… more

French and Canadian Inclusive Language Doctrine and Societal Attitudes

Description: One of the most important French grammar rules is the rule of superiority: Masculine subjects always trump feminine subjects when there are multiple subjects. Superiority is closely followed by the acceptance that all nouns have a grammatical gender, either masculine or feminine. Since 1984, and over the span of forty years, these rules have been challenged on multiple levels of French society. The research conducted over the course of this thesis focuses on the mentality and reactions of the F… more

How Much Does Sleep Vary from Night to Night? A Quantitative Summary of Intraindividual Variability in Sleep by Age, Gender, and Racial/Ethnic Identity

Description: Habitual (i.e., average or typical) sleep duration and sleep efficiency vary widely by demographic characteristics, including age, gender, and racial/ethnic identity. Despite a wealth of studies on demographic patterns in habitual sleep, these results are often based on cross-sectional surveys, which ask participants to retrospectively recall their "typical" or "recent" sleep. Yet, sleep is a highly dynamic behavior and may fluctuate substantially from night-to-night. This intraindividual varia… more
