Geolocation Of Monitoring Wells Using Small Unmanned Aircraft Systems, Joel Deyoung

Graduate Theses and Dissertations

Groundwater monitoring wells are commonly installed on a property as part of an environmental investigation to observe hydrological subsurface conditions, facilitate the collection of groundwater samples, and predict the flow of groundwater across a site. In addition to their installation, monitoring wells should be surveyed or mapped as accurately as possible. Traditional surveying techniques have employed the use of global navigation satellite systems (GNSS) technologies or other surveying equipment. A common surveying approach is to use real-time kinematic (RTK) GNSS to accurately measure the coordinates of each monitoring well on the site.In recent years, drones, or small unmanned aircraft systems …

Assessing Impacts Of Winter-Hay Feeding On Soil And Forage Nutrient Dynamics In A Rotationally-Grazed Pasture System In Arkansas, Lawrence Gordon Berry Iv

Graduate Theses and Dissertations

More than 38 % of United States’ rural land area was used for grazing (i.e., pastureland or rangeland) ruminant animals in 2017, constituting the largest private land use group. The expansive nature of these lands means that grazing and pasture management decisions have potential to impact water quality as well as profit margins. As a result, beef producers are under increased pressure from economic and environmental standpoints to limit application of nutrients beyond those required to grow the forage needed for animal consumption. At the same time, a large amount of nutrients is recycled back to pasture systems directly from …

Oklahoma Public Comprehensive Universities: The President's Role In Financial Management And Fundraising, Mark Bradley Shields

Graduate Theses and Dissertations

Oklahoma public comprehensive university presidents face many challenges. Among the top challenges is the quest for adequate funding of their institutions, including adequate levels of support from state resources. For Oklahoma’s public comprehensive universities and their leaders, the low levels of public support by the state have become a pattern, rather than an anomaly. The statewide reductions in appropriations for higher education funding have had a disproportionate effect on Oklahoma’s public comprehensive universities because they have fewer diversified revenue sources. As a result, Oklahoma public comprehensive university presidents have been forced to become more adept at budgeting, financial management, fundraising, …

Managing Climate Change And Weather Extremes For Nature-Based Tourism Organizations In The United States, Siyao Ma

Graduate Theses and Dissertations

Weather and climate serve as profound motivators for tourism travels. Much of the United States (US) has experienced a warming trend as well as higher extreme weather frequency, and the trends are projected to be continued. Consequently, the changing climate is expected to have both direct and indirect impacts on tourism decision-making and travel patterns due to the complex relationship between climate, weather, and outdoor recreation. Climate resources capture the integrated effects of varied meteorological variables that interact with humans in different ways and can be categorized along a spectrum of quantifiable values. This dissertation proposed a Camping Climate Index …

Spatial Assessment Of Urban Growth In Cities Of The Decapolis; And The Implications For Modern Cities, Wade A. Pierson

Graduate Theses and Dissertations

The Levant’s Decapolis was a network of ten cities in Greco-Roman Israel, Jordan, and Syria that established a thriving economic community. The Decapolis was home to ancient and modern cities like Damascus (Dammásq) and Amman (Philadelphia). Despite the various origins of these cities, Roman administration and their city planners oversaw the implementation of idealized Roman city form throughout the region. Three Decapolis cities represent intriguing examples of the larger confederation. Philadelphia (Amman), Gerasa (Jerash), and Gadara (Umm Qais) represent cities of common original urban form which developed drastically diverse urban morphologies over time.

Spatial analyses of these cities required working …

Rewriting Web 2.0 Discourses Of The Local For Socio-Spatial Literacy Theory, Erin Daugherty

Graduate Theses and Dissertations

This dissertation seeks to provide a framework for engaging with two spatial concepts that have been foundational to theorizing literacy across time but have often been taken for granted as passive backdrops to the social action of literacy practice: the notions of “the local” and “the global.” By interrogating the histories, both past and ongoing, of these two spatial concepts as they are interwoven into the sociocultural paradigm of literacy theory, research, and pedagogy, this project identifies new ways that literacy researchers and educators can attend to spatial concepts so as to promote and encourage literacy research and learning that …

Envisioning A New Pakistani Home: Gender, Class, And Identity In Women’S Urdu Journals, 1947-1960, Mehreen Jamal

Graduate Theses and Dissertations

The women’s journals published in Urdu during the first decades of Pakistan were vital to understanding the middle-class aspirations for a new national identity, since independence raised concerns among the dutiful citizens for the reformation of the new society, particularly concerning private lives. The writers and readers of these journals belonged to a generation whose lives and ideas had been formed by the Muslim reform literature of late nineteenth and early twentieth centuries. From the independence of Pakistan in 1947 to roughly the 1960s, writers in women’s journals engaged in refashioning the ideas of a new Pakistani middle-class respectability, foreseeing …

Over the last three to four decades, …

Racial Terror Lynching In Northwest Arkansas: Recounting Of The Story Of Three Enslaved Males Lynched In 1856 In Washington County - Documentary, Obed Lamy

Graduate Theses and Dissertations

While Northwest Arkansas is considered as diverse and progressive today, it also shares a common history of racial violence, and yet almost unknown, with the Southern United-States. Little is being said about the slave plantations in Elkins, racial cleansing in Springdale, or public spectacle lynchings in Fayetteville. This is because white people who hold political and economic power also control how history is written and decide what is to be learned from their perspectives. Marginalized communities, especially Black people, have not always had agency to tell their own stories. The lynchings of three enslaved males, Anthony, Aaron, and Randall, in …

Investigating The Role Of Social Capital And Everyday Communication In Campus Community Resilience During The Covid-19 Pandemic, Kaleb A. Turner

Graduate Theses and Dissertations

This thesis investigated the role of social capital and everyday communication in campus community resilience capacities during the COVID-19 pandemic. This study conceptualized the university community as a micro-community that experienced sharp disruption as a result of the COVID-19 pandemic. In the same way that traditionally conceptualized communities harness communication to build resilience, this study provides evidence that micro-communities, such as the university campus, have the same potential. Focus groups with students, faculty, and staff, as well as one-on-one semi-structured interviews with students, resulted in 557 pages of single-spaced transcripts that provided rich data to understand this community resilience context. …

Examining The Demographic And Situational Characteristics That Predict News-Media Coverage Of Bias Homicides:, Caitlin Tidwell

Graduate Theses and Dissertations

Recent trends indicate that incidents of hate crime have become increasingly more violent since 2017, resulting in an overall increase in incidents of bias homicide specifically. Knowledge of bias crime among the general public largely derives from news media sources and, unfortunately, research that illustrates how the media covers and/or portrays bias crime incidents remains underdeveloped. Using theories of strategic news making, the current study examines the types of bias homicide incidents that receive media coverage by constructing a unique database of newspaper articles from prominent, national papers for 216 bias homicides that occurred between 2000 and 2019 drawn from …

Role Of Reptile-Invertebrate Interactions In Enigmatic Reptile Declines, Meredith Swartwout

Graduate Theses and Dissertations

Reptile populations are declining world-wide and the mechanisms behind many of these declines remain enigmatic. Food web interactions (i.e., reduced prey availability or increased predation) have been implicated behind some reptile declines. However, relatively little is known about predation on lizard and snake eggs, despite egg survival being important for population dynamics of some species. Ants are important predators of squamate reptile eggs in tropical and temperate systems. In Costa Rica, long-term declines in terrestrial anole lizards were linked with reduced leaf litter depth, a factor that could influence egg vulnerability to ant predation. Fire ants (genus Solenopsis) are aggressive …

The Impact Of Media Algorithms On The Habermassian Public Sphere And Discourse, Kendal Heavner

Graduate Theses and Dissertations

Media algorithms are increasing in use among popular social networking sites (Geiger, 2009).Algorithms are used to sort a users’ social media feed based on relevance and interest rather than content publish time (Geiger, 2009). Widely accepted and recognized as influential in the media sector, algorithms create a highly personalized experience for the individual viewer. However, some scholars argue the specified curation of media based on a user’s personal preferences leads to a “filter bubble,” an online-based self-fulfilling prophecy in which users’ pre-existing opinions are continually reaffirmed. Because of this, this thesis will examine the intersection of algorithms and media theory. …

A Methodological Framework To Evaluate Community Perceptions Of Economic And Safety Impacts Attributed To Highway Bypass And Widening Projects, Karla Diaz-Corro

Graduate Theses and Dissertations

Transportation practitioners have proposed the construction of highway bypass and widening projects in rural communities to address traffic-related problems that include noise pollution and congestion, among others. In the past, the construction of bypass projects has led community residents to raise concerns about potential decreases in business activity for businesses located along the bypassed road. For transportation organizations, it is essential to understand the economic, social, and safety impacts of transportation projects in terms of public perceptions as public input is a required part of the project planning phase. Moreover, it is recommended that agencies perform retrospective analyses of project …

Providence Lost: Natural And Urban Landscapes In H. P. Lovecraft's Fiction, Dylan Henderson

Graduate Theses and Dissertations

S. T. Joshi, the preeminent scholar of weird fiction, considers H. P. Lovecraft a “topographical realist,” noting that, in his later fiction, Lovecraft creates realistic and painstakingly detailed settings. In “Providence Lost: Natural and Urban Landscapes in H. P. Lovecraft’s fiction,” I explore the significance of Lovecraft’s topographical realism and trace its evolution through Lovecraft’s career. I argue that Lovecraft’s early fiction, the tales, that is, that he wrote from 1917 to 1924 under the influence of Edgar Allan Poe and Lord Dunsany, pays little attention to the natural landscape, though Lovecraft does, in story after story, allude to fabulous, …

Gentrification And Income Segregation In Fayetteville, Arkansas, Willie Benson

A Mixed-Methods Analysis Of Biofuels, Teresa Cristina Garcia

Graduate Theses and Dissertations

Brazil has the largest sugarcane acreage in the world (FAOSTAT, 2020) and is the world leader in the production of sugarcane-based ethanol (Sousa Junior et al., 2017). Due to the technical experience in the production of biofuels and the availability of sugarcane straw and bagasse, the country has a great potential to commercially produce second-generation ethanol (E2G) (Nyko et. al., 2010). In 2017, Brazil enacted a new National Biofuels Policy, called RenovaBio, to expand the production and use of biofuels in the country. This dissertation combines three essays that explore biofuels law and policy with a special focus on Brazil. …

Quantifying The Simultaneous Effect Of Socio-Economic Predictors And Build Environment On Spatial Crime Trends, Alfieri Daniel Ek

Graduate Theses and Dissertations

Proper allocation of law enforcement agencies falls under the umbrella of risk terrainmodeling (Caplan et al., 2011, 2015; Drawve, 2016) that primarily focuses on crime prediction and prevention by spatially aggregating response and predictor variables of interest. Although mental health incidents demand resource allocation from law enforcement agencies and the city, relatively less emphasis has been placed on building spatial models for mental health incidents events. Analyzing spatial mental health events in Little Rock, AR over 2015 to 2018, we found evidence of spatial heterogeneity via Moran’s I statistic. A spatial modeling framework is then built using generalized linear models, …

The Surveillance Of Gastrointestinal Parasitic Nematodes Of Northwest Arkansas Dairy Cattle Using Traditional And Genetic Parasitological Identification Procedures, Eva M. Wray

Graduate Theses and Dissertations

Traditional and genetic parasitological identification procedures were compared using naturaland artificial nematode parasite infections in Holstein steer calves. The traditional parasitological procedures measured fecal egg counts, coprocultures with subsequent larval collection and adult nematodes collected at necropsy. The genetic identification procedures measured ITS-2 sequences extracted from different stages of nematode development: raw feces, concentrated nematode eggs, third stage larvae and adults. The primary nematodes observed were Cooperia oncophora, Cooperia punctata and Ostertagia ostertagi. The traditional techniques were not significantly different from one another, while the genetic sequencing showed variation amongst the different procedures. The raw feces sequences showed the most …

Graduate Theses and Dissertations

Climate change affects water resources differently across geospatial regions in the United States (U.S). There is a concern of how water availability will be affected by changes in long-term temperature and precipitation patterns, specifically in major production regions for eight fruit and vegetable crops. The effects on surface water available for irrigation use and supply stress in five regions containing 31 Agricultural Statistics Districts (ASDs) were assessed. The Water Supply Stress Index Model was used and modified to project water available for irrigation use across nine climate scenarios driven by historical data, five General Circulation Models, two population scenarios, and …

Commodity-Based Freight Activity On Inland Waterways Through The Fusion Of Public Datasets For Multimodal Transportation Planning, Magdalena I. Asborno

Graduate Theses and Dissertations

Within the U.S., the 18.6 billion tons of goods currently moved along the multimodal transportation system are expected to grow 51% by 2045. Most of those goods are transported by roadways. However, several benefits can be realized by shippers and consumers by shifting freight to more efficient modes, such as inland waterways, or adopting a multimodal scheme. To support such freight growth sustainably and efficiently, federal legislation calls for the development of plans, methods, and tools to identify and prioritize future multimodal transportation infrastructure needs. However, given the historical mode-specific approach to freight data collection, analysis, and modeling, challenges remain …
