Forget About Ferpa: How Foia Protects Student-Athlete Privacy In The Nil Era, Kamron Cox Jan 2024

Forget About Ferpa: How Foia Protects Student-Athlete Privacy In The Nil Era, Kamron Cox

Vanderbilt Journal of Entertainment & Technology Law

The start of the name, image, and likeness (NIL) era stirred public fervor about the new earning potential of high-profile student-athletes. Since institutional policies and state laws governing NIL require student-athletes to broadly disclose information about their NIL activities to their respective institutions, the several state laws that follow the approach of the federal Freedom of Information Act (FOIA) can jeopardize the privacy of student-athlete NIL information. Major universities have repeatedly resorted to the unreliable defense of the Family Educational Rights and Privacy Act as well as sporadic state legislation to protect student-athlete privacy in the new NIL space. However, …

Reimagining Hunting Through Women's Decision Space, H. Nash Jackson Jan 2024

Reimagining Hunting Through Women's Decision Space, H. Nash Jackson

Electronic Theses and Dissertations

Approximately 14.4 million people hunt in the United States, yet only 3.1 million (22%) of these hunters are women. To enhance women’s participation, many state natural resource agencies aim to reduce barriers and create pathways for women to hunt. Previously, researchers surveyed women to understand and describe barriers to their full participation in hunting. However, this methodology often just quantifies the different barriers without describing the interconnectedness and how the complexity of barriers can impact women’s participation in hunting. This thesis instead took an inductive research approach with the goal of better understanding women’s perspectives when faced with complex barriers. …

Do Agricultural Commodity Price Spikes Always Stem From News?, Zhouxin Li

Electronic Theses and Dissertations

This study delves into the occurrence and differentiation of significant price jumps in agricultural commodity markets, challenging the conventional belief that such movements are solely driven by exogenous factors. Existing literature has primarily focused on the impact of news on agricultural commodity prices, neglecting the distinction between endogenous and exogenous price spikes. I aim to identify and categorize both types of price spikes in corn, soybean, and wheat futures markets. I propose a comprehensive methodology involving the collection of agricultural news, non-parametric price jump detection, and differentiation between exogenous (newsdriven) and endogenous (non-news related) price spikes. By utilizing intraday price …

Computational Characterization Of Extracellular Electro-Osmotic Flow During Tissue Repair, Ashley Jorgensen-Blocker Jan 2024

Computational Characterization Of Extracellular Electro-Osmotic Flow During Tissue Repair, Ashley Jorgensen-Blocker

Electronic Theses and Dissertations

Electrical stimulation (ES) therapy promotes the healing of chronic epidermal wounds and suppresses the degeneration of articular cartilage. Despite the success of ES therapy, the underlying mechanisms by which ES promotes tissue repair are largely unknown, preventing the standardization and optimization of treatments. One proposed mechanism involves electro-osmotic flow (EOF), electrically driven water flow generated within close proximity to the cell surface. EOF induces the transport of macromolecules and removes metabolic wastes and inflammatory molecules from these dense tissues through interstitial flow. This dissertation investigates the application of weak electric fields (EFs) to non-excitable cells and the generation of EOF …
