From Phenology To Yield Zones: Functional Clustering Of Satellite Time Series For Crop Growth Monitoring, Ikram Morso
From Phenology To Yield Zones: Functional Clustering Of Satellite Time Series For Crop Growth Monitoring, Ikram Morso
Graduate Theses and Dissertations
Remote sensing and land surface phenology provide a strong basis for characterizing crop development, but their usefulness for within-field yield-zone delineation depends on whether crop development is analyzed as a phenological trajectory and whether the resulting zones are evaluated with spatially defensible statistics. These questions are especially relevant in soybean production because soybean is one of the most important row crops in the United States and the country’s dominant oilseed crop. This relevance is strong in Arkansas, where soybean is a major component of agricultural production. In soybean production, within-field yield variability reflects the combined influence of soil properties, stand …

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 …

Lumbopelvic Kinematics And Muscular Co-Contractions In Walking Prior To And Immediately Following A Bout Of Prolonged Standing., Stephanie Cotariu
Lumbopelvic Kinematics And Muscular Co-Contractions In Walking Prior To And Immediately Following A Bout Of Prolonged Standing., Stephanie Cotariu
Graduate Theses and Dissertations
Background: Prolonged standing is a common daily activity in a wide array of occupations, and approximately 44% of sample populations develop low back pain (LBP) during prolonged standing. Prolonged standing-induced LBP developers (“Pain Developers”) are three times more likely to develop clinical LBP and can therefore be considered a pre-clinical LBP population. Changes in typical gait have been observed in LBP patients, and walking has been hypothesized as being protective or preventive against LBP development. However, it is unknown whether Pain Developers exhibit similar kinematic adaptations to chronic LBP patients during common daily activities, such as walking. The exact muscular …

Experimental evaluation highlighted the effects of task scheduling and blocking operations on the ESP32, and polling-based communication latency within the Modbus bridge. These findings reveal the architectural and computational trade-offs involved in extending Solid to constrained or protocol-bound …
Effects Of Wetting And Drying On Nutrient Mobilization In Aquatic Systems, Karessa Grace De La Paz
Effects Of Wetting And Drying On Nutrient Mobilization In Aquatic Systems, Karessa Grace De La Paz
Graduate Theses and Dissertations
Wetting and drying cycles are a fundamental, but underexplored, control on nutrient mobilization and transport in aquatic ecosystems. Such intermittency impacts approximately 60% of the world's streams and rivers, and the extent is expected to increase with future climate change. Additionally, aging reservoir infrastructure is driving restoration efforts, like large-scale drawdowns, that can expose benthic sediments to extended dry periods before refilling. Despite the prevalence of wet-dry cycles, how they influence nutrient transport and mobilization across different aquatic ecosystems remains poorly understood. To address this gap, this thesis presents two complementary studies exploring nutrient dynamics in Arkansas aquatic ecosystems that …

People are changing why they use social media, what used to be a way to unwind and stay in touch with old friends is now being used for something much different. This study looks into how young adults (ages 18–25) perceive and retain information from social media compared to traditional media. As social media increasingly functions as both an entertainment and news source, the distinction between it and traditional journalism continues to diminish. Using a quota sample of 300 participants, data were collected through a Qualtrics survey measuring media engagement, usage, perceived credibility, and knowledge retention. Participants were exposed to …
Religion, Crime, And The Mediating Effects Of Social Control And Self-Control, Parker Bowman
Religion, Crime, And The Mediating Effects Of Social Control And Self-Control, Parker Bowman
Graduate Theses and Dissertations
Past research on the relationship between religion and crime has found the two variables have a significant negative correlation. Currently, there are two main mechanisms used to explain this relationship: social control and self-control. Social control theorists argue that participation in religious organizations decreases criminal behaviors by increasing social bonds. Self-control theorists argue that religious norms and values decrease criminal behavior by increasing an individual's self-control. While both mechanisms have been well supported by research, there remains the question of which is the stronger mediator of the religion-crime relationship. This study seeks to answer this question by comparing the effects …

Just Because They Can, Doesn’T Mean They Will: College Students’ Use And Non-Use Of Alcohol Protective Behavioral Strategies, Patrick Walter Mcclain
Just Because They Can, Doesn’T Mean They Will: College Students’ Use And Non-Use Of Alcohol Protective Behavioral Strategies, Patrick Walter Mcclain
Graduate Theses and Dissertations
College students engage in high levels of alcohol consumption, which can increase their risk of alcohol-related negative consequences. To address this, researchers developed Alcohol Protective Behavioral Strategies (APBS), which are actions that students can take before or while drinking to limit their alcohol use and/or reduce their likelihood of experiencing drinking harms. However, students’ APBS use could depend on their perceived usefulness of these strategies, whether they engage in high-risk drinking, or both. Therefore, the present study aims to investigate: (1) what percentage of students (a) perceive each APBS as useful and (b) implement the APBS they find useful, (2) …
