Ꭰꮎꮰꭶ (Missing): A Phenomenological Study Of Native American Student Experiences In The Law School Setting, Christina Allene Shaw
Graduate Theses and Dissertations
The legal landscape for Native American people in the United States is ever evolving and highly nuanced, with its historical foundation anchored into the classical pilasters of American legal jurisprudence. Federal Indian law scholars place that historical foundation within the written opinions of Chief Justice Marshall dating back to the 1820s and 1830s (Fletcher, 2024). Although few law students will likely find themselves closely examining the unassigned readings of the Marshall Trilogy or contemporary federal Indian law, there is one small group of students in law school doing exactly that: Native American law students. American Indians and Alaska Natives are …

Ecological Elemental Homeostasis And Stoichiometric Shifts: Biotic Responses To Ionic And Viral Stress, Samuel Anthony Tooru Dias
Ecological Elemental Homeostasis And Stoichiometric Shifts: Biotic Responses To Ionic And Viral Stress, Samuel Anthony Tooru Dias
Graduate Theses and Dissertations
Anthropogenic activities are reshaping the elemental composition of freshwater ecosystems, often creating stoichiometric imbalances that influence the growth, physiology and interactions of aquatic organisms. Ecological stoichiometric theory (EST) provides a framework for examining these changes by linking organismal elemental regulation to broader ecosystem processes. While traditionally focused on elements, such as carbon (C), nitrogen (N), and phosphorus (P), emerging stressors highlight the need to expand this framework to be more elementally inclusive for the examination of novel interactions. My dissertation integrates abiotic (salinization) and biotic stressors (viral infection) into an EST framework to evaluate how these factors alter elemental regulation …

Performance And Feasibility Of Pasture Rangeland And Forage Insurance In The Delta Region, Walker Bradley Davis
Graduate Theses and Dissertations
Despite being available nationwide since 2016, enrollment in Pasture, Rangeland, and Forage (PRF) insurance remains low in many regions of the country. The program's performance also presents regional discrepancies, with loss ratios varying significantly. Studies that have simplified the complexity of interval selection for producers have been shown to positively affect PRF enrollment. Such studies remain limited in several forage-producing areas. This study aims to address the lack of information in Arkansas specifically. Arkansas has among the nation's lowest participation rates and loss ratios. Low loss ratios signal that participants pay more in premiums than received in indemnities and may …
Polymer-Enhanced Nanopore Sensing, Eugene Gyasi Agyemang
Polymer-Enhanced Nanopore Sensing, Eugene Gyasi Agyemang
Graduate Theses and Dissertations
The resistive pulse technique characterizes single analytes by detecting fluctuations in the ion current as they pass through a narrow orifice connecting two electrolyte-filled chambers, each containing a single electrode. The amplitude, shape, frequency, and duration of these fluctuations primarily provide information about the analyte’s size, shape, concentration, and net surface charge, respectively. One configuration for resistive pulse measurements is of an electrolyte-filled nanopipette immersed in a bath, where the nanopipette tip acts as the nanoscale orifice. It was previously shown that incorporating the large quantities polymer polyethylene glycol (PEG 8K, 50% w/v) into the external electrolyte bath dramatically enhanced …
