Tracing Hazing Across Adolescence: Examining How Prior Hazing Experiences Shape Hazing Motivation And Tolerance Among Newly Initiated Ifc Fraternity Members, John Michael Vanhorn May 2026

Tracing Hazing Across Adolescence: Examining How Prior Hazing Experiences Shape Hazing Motivation And Tolerance Among Newly Initiated Ifc Fraternity Members, John Michael Vanhorn

Theses and Dissertations

Hazing remains pervasive and underreported, disproportionately affecting adolescent and emerging adult men, particularly within athletic teams and fraternity contexts. Although hazing is most often studied within collegiate organizations, many students encounter hazing behaviors prior to college, yet little is known about how these early experiences shape later hazing perceptions, motivations, tolerance, and masculine norms. Grounded in Bronfenbrenner’s Process-Person-Context-Time (PPCT) model, this dissertation conceptualizes hazing as a developmental process shaped by repeated social interactions, individual characteristics, contextual environments, and time across adolescence and emerging adulthood. Using a two-paper approach with a quantitative, longitudinal survey design, study 1 examined fraternity new members’ …


Improving And Supporting Flight Instructor’S Decisions For First Solo, Isabella Piasecki May 2026

Improving And Supporting Flight Instructor’S Decisions For First Solo, Isabella Piasecki

Theses and Dissertations

Flight instructors have the burden of determining when a student is ready for their first solo flight, and many have expressed uncertainty over their own decision-making skills during this phase of a student’s training. Prior studies have examined flight instructors’ pre-solo decisions in other countries, but no such study has been conducted with American flight instructors. For this study, current flight instructors with multiple prior endorsements for a student pilot’s first solo were interviewed to identify the more abstract concepts they use to guide their decision. Qualitative themes were identified from their experiences. Using this information, a checklist was developed …


Delayed Timing Of Spring Application Of Nitrogen In Corn, Elizabeth Mae Worley May 2026

Delayed Timing Of Spring Application Of Nitrogen In Corn, Elizabeth Mae Worley

Theses and Dissertations

Application timing of nitrogen (N) fertilizer within the corn growing season can be crucial to crop nutrient uptake and availability. A lack of region-specific timing recommendations may result in inefficient fertilizer use and inconsistent yield responses. The objectives of this study were to determine how late in the growing season a first and second N fertilizer application can be pushed until corn yield is impacted and investigate whether Growing Degree Days (GDDs) should be used as better estimate of timing for N application than calendar date or growth stage. First applications were able to be delayed until V4-V6 growth stages …

Assessing Biotic And Abiotic Drivers Of Hybridization And Species Delimitation In A Highly Reticulate Syngameon, Nicholas John Engle-Wrye May 2026

Assessing Biotic And Abiotic Drivers Of Hybridization And Species Delimitation In A Highly Reticulate Syngameon, Nicholas John Engle-Wrye

Theses and Dissertations

Hybridization, or the flow of genetic materials between varieties or species, shapes evolution by generating novel genotypes, altering allele frequencies, and driving diversification. Yet, the rate at which hybridization occurs is heterogeneous across the tree of life and the ecological and evolutionary factors that govern its occurrence remain poorly understood. This dissertation examines how conserved biotic and abiotic niches influence hybridization and uses integrative methods to delimit species boundaries within Heuchera (Saxifragaceae), a genus notable for widespread interspecific gene flow and cryptic morphological diversity. Results reveal that hybridization is most frequent where pre- and postzygotic barriers are weak, as with …

Monotone Traveling Waves In A General Discrete Model For Populations With K-Generation Long-Term Memory, Austin Kernel Sanders May 2026

Monotone Traveling Waves In A General Discrete Model For Populations With K-Generation Long-Term Memory, Austin Kernel Sanders

Theses and Dissertations

We investigate the spatial dynamics of a population modeled by a general discrete integrodifference equation incorporating k-generation long-term memory. While classical models rely solely on the im- mediately preceding state to determine population growth and dispersal, introducing multiple past states causes the associated evolution operator to lose compactness. Consequently, standard fixed- point theorems are insufficient to prove the existence of traveling wave solutions. We overcome this difficulty by constructing a time-independent moving frame operator and employing the monotone iteration method. By assuming the fecundity function is locally Lipschitz, bounded, and nondecreasing on a specified interval, and by relaxing continuity requirements …

Sentential Structures In Alexander Scriabin's Op. 8 Etudes, John Paul West May 2026

Sentential Structures In Alexander Scriabin's Op. 8 Etudes, John Paul West

Theses and Dissertations

Historically, the sentence has proven to be one of the most versatile and pervasive forms in music, appearing since the mid-sixteenth century with occurrences too frequent to quantify. Sentential musical phrases emerged from music and poetry during the late-sixteenth and early-seventeenth centuries with the same short-short-long rhythmic impulse, originating from poetic and sing-song texts. Although the sentence is most often tied to the Classical period, it is not associated with any single era. Patterns of sentential phrases were already apparent and plentiful before the late eighteenth century, and composers used it as a device to expand musical form throughout the …


Optional Freedom: The Idea Of Voluntary Slavery In Antebellum Law And Literature, Vinh T. Pham May 2026

Optional Freedom: The Idea Of Voluntary Slavery In Antebellum Law And Literature, Vinh T. Pham

Theses and Dissertations

This thesis elaborates “voluntary slavery” as a problem for thought for both proslavery legalists and literary writers in the antebellum period. It takes as its point of departure the passage of Southern laws throughout the 1850s that provided free Black persons the option to petition for self-enslavement to a master/mistress of their choice, and the safeguards within them that led a significant number of such petitions to be rejected. Given the political tensions of the 1850s, why would legal practitioners actively impede the option of self-enslavement? Implicit in these rejections is the possibility that self-enslavement was in some way a …
