Investigating Culicoides Diversity, Distribution, And Behavior In Arkansas, Cassandra Steele
Investigating Culicoides Diversity, Distribution, And Behavior In Arkansas, Cassandra Steele
Graduate Theses and Dissertations
Culicoides biting midges (Diptera: Ceratopogonidae) are globally important vectors of pathogens affecting livestock and wildlife. In the United States (US), transmission of bluetongue virus (BTV), epizootic hemorrhagic disease virus (EHDV), and vesicular stomatitis virus (VSV) results in economic losses and periodic mortality events of wild and domestic ruminants. Culicoides sonorensis is the confirmed vector of BTV and EHDV in the western regions of the US, however this species is uncommon throughout much of the eastern and southeastern US, where hemorrhagic diseases remain endemic. There are likely other putative vector species responsible for pathogen transmission. This research investigated Culicoides diversity, distribution, …
Characterization Of River Cane Morphology, Density And Biomass In Sun And Shade In Stream Riparian Zones In Northwest Arkansas, Emily Shy-Anne Carter
Characterization Of River Cane Morphology, Density And Biomass In Sun And Shade In Stream Riparian Zones In Northwest Arkansas, Emily Shy-Anne Carter
Graduate Theses and Dissertations
River cane, or Arundinaria gigantea Walter (Muhl.), ecosystems serve as ecological and cultural keystones, offering wildlife habitat, streambank stabilization, and construction/craft material for Native groups who utilize river cane. However, these ecosystems have declined substantially because of overgrazing, land conversion, and fire suppression, resulting in reduced patch size and culm morphology. Historically widespread across floodplains and riparian zones, canebrakes, or monotypic forests of river cane, have been restricted to small fragments. This study evaluated how canopy cover influences light availability, culm morphology, density, and biomass of river cane across eight riparian sites in Northwest Arkansas to inform restoration efforts. Light …

Graduate Theses and Dissertations
The proliferation of commercial probe data vendors has posed both opportunities and challenges for transportation agencies regarding the choice of reliable vehicle probe data for decision making purposes. Probe data is a form of passive mobility data representing a small fraction of the traveling population. Vendors aggregate mobility data from different sources including GPS enabled smartphones, telematics systems, and connected vehicles. They possess unique data collection methodologies, sampling mechanisms, and expansion algorithms which introduce variability in derived traffic performance measures like speed and volume. The overall objective of this work is to assess similarities and differences among probe data vendors …
Univariate And Bivariate Binary Spatial Regression Models With Application To Plant Abundance Data, Amir Hamza Akash
Univariate And Bivariate Binary Spatial Regression Models With Application To Plant Abundance Data, Amir Hamza Akash
Graduate Theses and Dissertations
Analyzing species distributions is of prime interest in ecological research. Prevalence of a species usually depends on several environmental and topographic features not all of which can be quantified or measured. Spatial random effects play an important role as a surrogate for missing features that can explain similarity in species prevalence patterns between neighboring locations. In this thesis, we focus on a dataset on abundance of plants in the southern part of South Africa. First, we build a hierarchical Bayesian model for binary regression, using the probit link, on presence/ absence of a species based on available covariates. Since the …

Drawing Conclusions: Autonomy And Mental Maps In Denmark And The Faroe Islands, Erik Steven Breidinger
Drawing Conclusions: Autonomy And Mental Maps In Denmark And The Faroe Islands, Erik Steven Breidinger
Graduate Theses and Dissertations
This dissertation develops and tests a comparative heuristic device called optimal autonomy to explain when and how autonomous territories, or simply autonomies, become durable components of the global system of sovereign states. Drawing on a mixed‑methods case study of Denmark and the Faroe Islands, the study operationalizes optimal autonomy as a heuristic device using three interacting metrics: territorial delineation, national distinction, and state dependence. Using semi‑structured interviews with public officials and a mental‑mapping experiment with university students, this research shows that optimal autonomies are not made from single institutional designs but rather a dynamic equilibrium between maximal territorial delineation, medial …
Online Sports Betting Legalization And The Reallocation Of Retail Investor Information Search Toward Lottery-Type Stocks, Jared Richard Stark
Online Sports Betting Legalization And The Reallocation Of Retail Investor Information Search Toward Lottery-Type Stocks, Jared Richard Stark
Graduate Theses and Dissertations
I examine whether the legalization of online sports betting is associated with a reallocation of retail investors' information search across stocks around firm earnings announcements (EAs). Prior work links legalization to a reallocation of household capital, but its association with information search has not been examined. Exploiting the staggered timing of legalization following Murphy v. NCAA, I use four treated and four matched control states over 2017-2024 and measure search using state-level Google Trends data for firm tickers. Treated and control states are already on different trajectories before any legalization, which confounds the average-level comparison. The association I can document …
Arkansas’ Crippled Children’S Homes & The Politics Of Polio, Rylie Ford
Arkansas’ Crippled Children’S Homes & The Politics Of Polio, Rylie Ford
Graduate Theses and Dissertations
Most of the work in the field of disability history has centered on the Northeastern part of the United States and regions with large urban centers, therefore, excluding Southern and rural perspectives. This omission is particularly problematic when roughly 79% of the Black population in the United States lived in the South in 1940. The aim of this study is to contribute a Southern perspective to disability studies and Black medical history by tracing the development of services and aid for children with physical disabilities in Arkansas. Employing the frameworks from the social model of disability and Black disability politics, …

Fugue State: The Body Politic Of Identity Theatre, Sean Patrick Ryan
Graduate Theses and Dissertations
This paper will cover my approach as an actor and a creator in two separate productions during my time at the University of Arkansas. The first is a solo theatre piece that I devised under the tutelage of Michael Landman. This work, Half Brother, is a piece of theatre that takes an abstract approach to exploring the familial and psychological ripples that can occur in the life of a queer person when a parental unit takes on a political and religious identity that is oppositional to the LGBTQ community. It exposes the effect this transformation has on the child, their …
Grazed Pasture Effects On Greenhouse Gas Emissions In The Ozark Highlands, Tyler Buchanan
Grazed Pasture Effects On Greenhouse Gas Emissions In The Ozark Highlands, Tyler Buchanan
Graduate Theses and Dissertations
In the United States (US), grazinglands serve as the main foundation for the livestock industry, and, in Arkansas specifically, pastures are essential for rotational grazing and dairy operations. Climate change is increasingly becoming a concern in the agriculture industry, largely caused by anthropogenic activities increasing greenhouse gas (GHG) concentrations in the atmosphere, at least partly due to the nutrient recycling that occurs from animal manure additions in grazinglands. Therefore, quantifying GHG emissions from pastures is essential to better understanding the impacts of grazing on the environment. The objective of this study was to quantify and evaluate the potential effects of …
Modeling Bicycle Ridership In Northwest Arkansas, Nelofar Qulizada
Modeling Bicycle Ridership In Northwest Arkansas, Nelofar Qulizada
Graduate Theses and Dissertations
In a global comparison, the U.S. ranks second lowest in bicycle use for urban trips, surpassed only by Brazil. This underutilization signals missed opportunities to improve public health, environmental sustainability, and community connections. In Northwest Arkansas (NWA), a region actively investing in active transportation infrastructure, efforts were underway to reverse this trend. However, a key question remained: Were these investments effectively boosting bicycle ridership? To address this question, communities required reliable methods to measure cycling activity. Traditionally, this involved stationary counters placed at strategic locations to monitor ridership patterns. While accurate, these counters had limited spatial coverage. In contrast, emerging …

Graduate Theses and Dissertations
The increased usage of unmanned aircraft systems (UAS) for various applications has broadened access to high-resolution aerial imaging, a field with deep roots in geography, remote sensing, and geospatial science. Radiometric correction in satellite imagery has its origins in the early decades of Earth observation, with foundational work beginning alongside the launch of the first multispectral satellites and evolving through decades of research into atmospheric correction, sensor calibration, and reflectance modelling. As UAS adoption grows, research into atmospheric attenuation effects on UAS imagery becomes necessary. Empirical line calibration converts digital number values to surface reflectance and is used here to …
Misusing Mariátegui: The Strategic Use Of José Carlos Mariátegui By Peru’S Sendero Luminoso, Shaylee Luedders
Misusing Mariátegui: The Strategic Use Of José Carlos Mariátegui By Peru’S Sendero Luminoso, Shaylee Luedders
Graduate Theses and Dissertations
The Peruvian Communist Party - Sendero Luminoso (SL) was a violent communist guerrilla group that was active in Peru in the 1980s and early 1990s. SL’s guiding ideology was “Gonzalo Thought,” named for the Party’s leader, Abimael Guzmán, who was known to his followers as Presidente Gonzalo. Greatly inspired by Marxism-Leninism-Maoism, Gonzalo Thought also drew heavily from the work of José Carlos Mariátegui, an early 20th-century socialist Peruvian intellectual. One of Mariategui’s key ideas held that the Inca Empire was communist and that living Indigenous Peruvians retained this pre-modern “communist spirit.” For him, this meant that authentic Peruvian institutions and …
Unveiling Factors Influencing Extract Yield From Milled Rice In Brewing, Matthew Aitkens
Unveiling Factors Influencing Extract Yield From Milled Rice In Brewing, Matthew Aitkens
Graduate Theses and Dissertations
Rice (Oryza sativa L.) presents a locally sourced, climate-resistant starch source for the brewing industry. As barley faces increased uncertainty due to rising temperatures, Arkansas-grown rice offers a more stable and cost-effective alternative starch source. However, the use of milled adjunct rice by brewers has remained limited, largely due to knowledge gaps about cultivar-specific properties relative to brewing. Chapter 1 provides an overview of rice as a brewing adjunct, reviewing the physiochemical properties important to brewing success. These properties include kernel size, kernel breakage, amylose content, and gelatinization temperature. Mashing strategies for multiple different brewing layouts are overviewed, showing practical …
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 …

From Classroom To Courtroom: How Educational Strains Shape Juvenile Delinquency, Hailey Elizabeth Houston
Graduate Theses and Dissertations
Juvenile delinquency is a significant social issue with consequences that extend into adulthood and impact future success of youth. Although prior research has explored various factors that affect juvenile delinquency, notable gaps remain – notably a lack of literature on how educational strain effects juvenile delinquency with a focus on rural areas. This study addresses these gaps by examining the effects of educational strain, such as poor academic performance and lack of teacher support, on rural adolescents’ engagement in juvenile delinquency. Data for this study was obtained from the 2023 National Survey on Drug Use and Health (NSDUH), an online …
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 …

No Place But Here, Dillon Bryant
Graduate Theses and Dissertations
The writing in this document is a dovetailing of fragments ranging from critical inquiry, analysis, scripts, and other observations that relate to the body of work in “No place but here”. It is an accompanying document attempting to enrich the visual work rather than a direct illustration. The installation of “No place but here” at the Rogers Creamery is an investigation utilizing collage, text, and other constructed photographs, images, and objects to play with and against familial and broader narratives of power, control, and ambiguity associated with the American West. Underpinned and intersected by interior questions revolving around artifice, connection, …
An Experimental Study On Gendered Leadership Effects In Neighborhood Climate Protests, Farzana Fahmee
An Experimental Study On Gendered Leadership Effects In Neighborhood Climate Protests, Farzana Fahmee
Graduate Theses and Dissertations
Leaders are at the frontline as they determine the attitude that audiences have towards social movements and the level of attention they are willing to give to those movements. This paper investigates the influence of a neighborhood environmental protest leader’s gender on perceived leadership and democratic participation. The study relies on self-categorization theory, social identity theory, and the concept of issue-fit to assert the possibility of women gaining from the cultural connection between environmental care and femininity, while also experiencing backlash due to the masculine coding of leadership. A post-test online experiment involving 189 university students was conducted in which …

Of Dunes And Ice: A Surface-Atmosphere Investigation Of Mars Co2 Sublimation Features And Titan Aeolian Fields, Racine D. Cleveland
Of Dunes And Ice: A Surface-Atmosphere Investigation Of Mars Co2 Sublimation Features And Titan Aeolian Fields, Racine D. Cleveland
Graduate Theses and Dissertations
This dissertation investigates a central question: How do planetary boundary layer processes manifest in observable surface geomorphology, and how can planetary imagery be used to quantify those effects? The planetary boundary layer (PBL) governs near-surface exchanges of momentum, heat, and volatiles, yet direct atmospheric measurements remain spatially and temporally limited on most planetary bodies. By analyzing geomorphic features preserved in high-resolution imagery, this work quantifies how boundary-layer processes leave measurable signatures on planetary surfaces. For Mars, high-resolution images from the Mars Reconnaissance Orbiter (MRO) HiRISE instrument were used to map CO2 sublimation features, or Swiss Cheese Features (SCFs), on the …

Geospatial Analysis Of The Influence Of Wastewater Disposal On The Induced Seismicity In Oklahoma, Usa, Kristine Nagy
Graduate Theses and Dissertations
Seismic records over the past decade and a half have indicated a significant increase of earthquakes in the state of Oklahoma and the evidence has strongly suggested the rise is likely caused by substantial wastewater disposal operations, a subsequent process of oil and natural gas extraction. This study investigated the relationship between wastewater disposal via injection wells, and its influence on inducing earthquakes in Oklahoma by employing Geographic Information System (GIS) tools for geospatial data integration and spatial analysis using United States Geological Survey (USGS) earthquake data and Underground Injection Control (UIC) Class II well data sourced from the Oklahoma …
Writing Through The Plague: Memory, Trauma, And Survival In Arabic And English Narrative, Zainab Abbood Jawhar Aldaoseri
Writing Through The Plague: Memory, Trauma, And Survival In Arabic And English Narrative, Zainab Abbood Jawhar Aldaoseri
Graduate Theses and Dissertations
This thesis examines how Arabic and English literary and intellectual traditions responded to the Black Death as a shared yet differently articulated experience of collective trauma. Drawing on trauma theory, particularly the work of Cathy Caruth and Dominick LaCapra, it analyzes how plague narratives function as cultural mechanisms for processing mass suffering. Through a comparative study of Arabic historiographical, theological, medical, and poetic texts alongside English allegorical, mystical, autobiographical, and satirical writings, this project argues that both traditions developed distinct narrative strategies to render the trauma of plague intelligible. Arabic plague literature, represented by figures such as Ibn Khaldūn, Ibn …
Old-Growth Surveys And Landowner Outreach In The Cross Timbers Of Oklahoma, Jon Webb
Old-Growth Surveys And Landowner Outreach In The Cross Timbers Of Oklahoma, Jon Webb
Graduate Theses and Dissertations
The Cross Timbers ecoregion represents a critical ecologic transition zone, spanning approximately 17 million acres across Oklahoma, Texas, Kansas, and Arkansas. Situated between eastern deciduous forests and the southern Great Plains, the Cross Timbers are dominated by drought-tolerant post oak (Quercus stellata) and blackjack oak (Quercus marilandica). Despite retaining some of the most extensive old-growth forests in the eastern United States, this ecoregion remains threatened by urban expansion, agricultural conversion, altered fire regimes, and eastern red cedar (Juniperus virginiana) encroachment. This project sought to identify, survey, and document large, previously un-surveyed or unreported tracts of old-growth Cross Timbers in Oklahoma, …
Groundwater Responses To Tidal Restoration At Pelican Marsh And Sea-Level Rise In Elkhorn Slough, California, Julie E. Nelson
Groundwater Responses To Tidal Restoration At Pelican Marsh And Sea-Level Rise In Elkhorn Slough, California, Julie E. Nelson
Graduate Theses and Dissertations
Coastal wetlands represent a dynamic but vulnerable terrestrial-aquatic interface with future resilience controlled by historic hydrologic alterations, sea-level rise, and groundwater extraction. In diked coastal settings, poor tidal connectivity can degrade habitat from the impoundment of freshwater or hypersaline surface waters. Restoring tidal connectivity could foster marsh revitalization, but altering the surface hydrologic system could lead to unwanted salinity intrusion in shallow aquifers. Saline groundwater intrusion degrades freshwater quality and, while inevitable with sea-level rise, could be accelerated with tidal marsh restoration. To investigate this, I developed a steady-state groundwater flow model of Pelican Marsh, a diked, muted tidal marsh …
