Telling New Tales: Modernizations Of Chaucer In The Eighteenth Century, Eric Duane Larson

Graduate Theses and Dissertations

Any review of medieval culture and literature in the British eighteenth century requires some consideration for the modernizations of Chaucer’s Canterbury Tales. Effectively a collaboration that spanned the entire century, this project began with Dryden and Pope and continued in earnest with lesser-known poets like George Ogle and William Lipscomb. The resulting modernization of every Chaucerian tale between 1700 and 1795 revisits medieval themes, but it also displays contemporary anxieties through presentations of language, content, style, and rhetorical intent that are sometimes vastly different from Chaucer’s originals.

The modernization project is worthy of study, in particular because it reflects, across …

Hoc Est Corpus Meum: The Eucharist In Twelfth-Century Literature, Lindsey Zachary Panxhi

Graduate Theses and Dissertations

In “Hoc Est Corpus Meum: The Eucharist in Twelfth-Century Literature,” I analyze the appearance of the Eucharist as a sacred motif in secular lais, romances, and chronicles. The Eucharist became one of the most controversial intellectual topics of the High Middle Ages. While medieval historians and religious scholars have long recognized that the twelfth century was a critical period in which many eucharistic doctrines were debated and affirmed, literary scholars have given very little attention to the concurrent emergence of eucharistic themes in twelfth-century literature. This is unfortunate, since the Eucharist emerges as an intriguing motif, appearing in fantastic encounters …

Geospatial Analysis Of Droughts, Rice And Wheat Production, And Agrarian Vulnerability: A District-Level Study Of The Self-Calibrated Palmer Drought Severity Index In India, Aaron Michael Shew

Graduate Theses and Dissertations

Droughts have affected more people than any other natural disaster in the last century, causing billions in economic damages and millions of deaths. As the Sea Surface Temperatures (SST) have heated in the Indian Ocean, drought patterns across South Asia have changed; the Indian monsoon has become more volatile and less predictable. In this study, monthly self-calibrated Palmer Drought Severity Index (sc-PDSI) data for the time period between 1950 and 2009 were interpolated to India’s districts; then the data were analyzed for changes in frequency and severity. The data were further evaluated using Anselin’s Local Moran’s I Statistic to elicit …

The study looked at institutions classified as very high, high, or research universities by the Carnegie Classifications, and which offered online masters programs focused on preparing students for positions in educational administration or leadership roles. The study used an electronic survey and content analysis through institutional policy and quality assurance documents to develop a recommendation for institutional level quality …

Synthetic Aperture Radar Interferometry Analysis Of Ground Deformation Within The Coso Geothermal Site, California, Erik Vaughn Brawner

Graduate Theses and Dissertations

Earth’s surface movement may cause as a potential hazard to infrastructure and people. Associated earthquake hazards pose a potential side effect of geothermal activity. Modern remote sensing techniques known as Interferometric Synthetic Aperture Radar (InSAR) can measure surface change with a high degree of precision to mm scale movements. Previous work has identified a deformation anomaly within the Coso Geothermal site in eastern California. Surface changes have not been analyzed since the 1990s, allowing a decade of geothermal production impact to occur since previously assessed. In this study, InSAR data was acquired and analyzed between the years 2005 and 2010. …

Beyond "Main Street": Small Towns In Post-"Revolt" American Literature, Rachael Price

Graduate Theses and Dissertations

“Beyond Main Street” examines the impact and legacy of the literary movement that Carl Van Doren, in an infamous 1920 article from The Nation, referred to as the “revolt from the village.” This movement, which is widely acknowledged to encompass such writers as Edgar Lee Masters, Sherwood Anderson, and Sinclair Lewis, pushed back against the primacy of the heretofore-dominant pastoral tradition when it came to depictions of rural America. These authors sought to create a more accurate portrayal of the small town, one that, while not completely eschewing the pastoral, also exposed the more seedy side of village life. Critics …

Thermodynamic Modeling Of Aqueous Geochemistry Of Chlorine Salts: Application To Stability And Habitability Of Liquid Brines On Mars, Amira Elsenousy

Graduate Theses and Dissertations

The WCL (Wet Chemistry Lab) instrument on board the Mars’s Phoenix Lander has identified the soluble ionic composition of the soil at the landing site. Two important ions were detected at the landing site; perchlorates (ClO4-) with a concentration of ~ 2.4 wt% and chlorides (Cl-) with a concentration of 0.54 wt%. Between chloride and perchlorate ions three other oxidized ions exist and called chlorine ions: hypochlorite ClO - (ox. state +1), chlorite ClO2- (ox. state +3) and chlorate ClO3- (ox. state +5). These oxidized ions might be existed as intermediate species on the surface of Mars but remained undetected. …

Validation Of Soil-Test-Based Phosphorus And Potassium Fertilizer Recommendations For Rice And Soybean, Matthew Scott Fryer

Graduate Theses and Dissertations

The science of soil-testing for nutrient management and fertilizer recommendations is widely accepted among scientists and agronomists. Although this science is unsurpassed in predicting soil nutrient availability, soil-test interpretations are seldom validated. Major research objectives for irrigated soybean [Glycine max (L.) Merr.] and direct-seeded, delayed-flood rice (Oryza sativa L.) were to: i) validate the accuracy of Mehlich-3 soil-test P (STP) and K (STK) interpretations and ii) published critical tissue-P and -K interpretations in predicting the yield response to fertilizer at different significance levels (p≤0.05 to 0.25), iii) examine how seed nutrient concentrations are influenced by fertilization and crop response to …

Towards Systematic Selection Of Terrain- And Ground Cover-Specific Lidar Filtering Parameters, Vance Green

Graduate Theses and Dissertations

Accurate automated classification of LiDAR point clouds is a well-known problem and proper parameterization of the classification algorithm is essential to creating useful bare-earth terrain models. Parameterization is particularly important in areas characterized by extremely low relief, such as the Little Red River Irrigation Project Area in central Arkansas. In this kind of landscape, analyses such as hydrological flow models are sensitive to small changes in the topography, and therefore prone to errors in the classification of the LiDAR point cloud and the digital elevation models (DEMs) derived from it. Developing effective project-specific parameters requires a high degree of knowledge …

Modifying A Cow-Calf Biophysical Simulation Model For Analyses Of Alternative Enterprises, Jennifer L. Lutes

Graduate Theses and Dissertations

Cow-calf producers in the United States, tasked with providing beef calves for the beef industry, have had a multitude of difficulties to overcome in recent years. Producers in northwest Arkansas were negatively impacted by high hay prices coupled with low beef cattle market prices due to severe drought experienced in portions of 2010, 2011, and 2012. During this time they also faced high grain prices, due to a record low harvest, combined with portions of the corn harvest diverted from human and animal feed to ethanol production. Tight lending policies of this time, reminiscent of the housing market crash in …

Geospatial Workflows And Trust: A Use Case For Provenance, Rachel Frances Linck

Graduate Theses and Dissertations

At first glance the Astronomer by Vermeer, Tutankhamun’s burial mask, and a geospatial workflow may appear to have nothing in common. However, a commonality exists; each of these items can have a record of provenance detailing their history. Provenance is a record that shows who did what to an object, where this happened, and how and why these actions took place. In relation to the geospatial domain, provenance can be used to track and analyze the changes data has undergone in a workflow, and can facilitate scientific reproducibility. Collecting provenance from geospatial workflows and finding effective ways to use this …

Civil War Unionists And Their Legacy In The Arkansas Ozarks, Rebecca Ann Howard

Graduate Theses and Dissertations

More than a thousand men from northwest Arkansas served in the Union Army during the American Civil War. The conflict devastated a region that had previously enjoyed impressive economic growth. The years of suffering during the war eventually left the region largely depopulated. As people returned to the region after the war was over, unionists and their families fought not only to rebuild, but to secure the benefits they felt their loyalty to the federal government deserved. As unionists became Republicans in the decades after the war, Arkansas became a securely Democratic state. But Arkansas’s native Republicans leveraged their wartime …

Lithologic Controls On Bedrock Channel Morphology In The Buffalo River Basin, Evan A. Thaler

Graduate Theses and Dissertations

The longevity of high relief terrains in passive margin systems remains an explained phenomenon in geomorphology. Current landscape evolution models assume an equilibrium state between rock uplift rates and erosion rates. However, analysis of chi gradients of bedrock channels across several lithologies in the Buffalo River Basin reveals disequilibrium in the basin controlled by the presence of a thick interval of Pennsylvanian sandstone that caps many of the plateaus in the basin. Headwater channels beneath the caprock tend to have higher chi gradient values in all lithologies than headwater channels in basins where the sandstone caprock is absent. High chi …

“Maybe It Was You”: The Implications Of Southern Gothic Elements Of Criminality, Sexuality, And Race In Truman Capote’S In Cold Blood, Shirley Ellen Rash

Graduate Theses and Dissertations

Truman Capote’s In Cold Blood is frequently the subject of critical analysis of its genre, its factual accuracy, and its style. Previous critical examinations of the text often briefly acknowledged the thematic connections between this text and Capote’s previous southern gothic work but do so without substantially delving into these similarities. For many, the text’s Kansas setting prevents the book from properly being considered southern gothic because Kansas is commonly perceived as the most quintessentially wholesome and American of states while the U.S. South is frequently deemed the site of taboo and undesirable activity. This thesis questions this dichotomy and …

Architectures For A Future South: Posthumanism And Ruin In The Novels Of Cormac Mccarthy, Joshua Ryan Jackson

Graduate Theses and Dissertations

This thesis reads the novels of Cormac McCarthy as posthuman southern literature to explain why fiction from the South after World War II could no longer convey a sense of place during postmodernity: that is, because the region's culture and economy were transitioning from predominantly humanistic thinking (i.e., believing that humans [and especially southern humans] are supreme beings) to predominantly posthumanistic thinking (i.e., believing that humans are not as supreme as they think they are). It argues that we can trace this ideological change over time via structural shifts in the South’s architectural record, which we see in the ruins …

Socially Constructing Drug Addicts From The Poor: A Critical Discourse Analysis, Kalynn Susan Amundson

Graduate Theses and Dissertations

Welfare drug testing was authorized by the Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA) of 1996, and has subsequently garnered extensive legislative interest in numerous states. This policy raises several questions, which are the subjects of the two journal articles and one manuscript included in this dissertation.

The first article addresses the question of a possible confluence of War on Drugs and Welfare Reform policies as evidenced through welfare drug testing policy, and indicated by continuity in policymakers’ rhetoric. This study examines federal-level policymakers’ debate discourse in these two policy streams. The analysis finds themes of the Social pathology, …

A New Hope? A Critical Assessment Of Gentrification And Hope In Memphis, Tennessee, Daniel Russell Gadeke

Graduate Theses and Dissertations

Gentrification is the manifestation of the Social change within urban residential neighborhoods as a result of uneven development in cities. These gentrification processes are a contextually dependent phenomenon, which vary both spatially and temporally when compared betwixt cities. Since the 1990s, local and state governments have developed more creative discourses for the promotion of gentrification which have overshadowed the positive outcomes of gentrification. The adoption of neoliberal policies has attacked many forms of the Keynesian welfare-state, most notably federal public housing. The United States’ Department of Urban Housing and Development’s (HUD) initiative Homeownership Opportunities for People Everywhere (HOPE VI) emerged …

Solubility And Detectability Of Hydrocarbons On The Surface Of Titan, Sandeep Singh

Graduate Theses and Dissertations

Titan’s thick atmosphere is enriched with organic compounds and its surface holds reservoirs of hydrocarbons. This makes Titan the only other candidate in our solar system (apart from Earth) to have stable liquid at the surface. The stability and characteristics of liquid and ices on the surface of Titan are of high importance in understanding its surface-atmosphere interactions. Titan’s hydrological cycle is similar to what we see on Earth, with the exception of methane (CH4) and ethane (C2H6) taking the place of water. The smoggy atmosphere veils the surface of Titan from the view of Cassini spacecraft, except at seven …

Monochamus Titillator Oviposition And Intraspecific Competition In Shortleaf Pine Bolts, Ryan Patrick Rastok

Graduate Theses and Dissertations

Monochamus titillator (Coleoptera: Cerambycidae) feed on trees in the family Pinaceae as adults and larvae. Adults feed on healthy twigs and branches and oviposit on stressed, dead, or dying trees. Prior to oviposition, females construct pits on the bark surface using their mandibles. The number of eggs laid beneath bark, where oviposition pits have been constructed, varies greatly. Developmental time and adult body size also vary greatly. I investigated oviposition and intraspecific competition with the goal of determining the degree to which various insect densities and oviposition times impact the following: 1) oviposition pit construction; 2) egg deposition; 3) emergence, …

Immigrant Cosmopolitanism: Jewish-American Immigrant Narratives And Modernist Cosmopolitan Aesthetics, Mindy Renee Trenary

Graduate Theses and Dissertations

I propose to show in this study how Jewish-American authors of mass media immigrant works from the first three decades of the 20th century utilize a form of modernist cosmopolitan aesthetics to challenge notions that these works are unworthy of study and appreciation. These authors, not happy with the classifications and aesthetics available to them as immigrant authors, borrow from other ideologies and aesthetic schools to create an aesthetic system meeting the needs of immigrant individuals. In theory, this system, which I have termed 'immigrant cosmopolitanism,' meets the needs of these individuals and capitalizes on the authors' diverse backgrounds and …

Redefining Access To Public Space: Community Relations In A New Immigrant Setting, Aaron Isaac Arredondo

Graduate Theses and Dissertations

This article examines how and to what extent charging an entrance fee at a public recreational space in a new immigrant setting affects the participation of Latino and migrant population groups at The Jones Center for Families (JCF) in Springdale, Arkansas. This study also documents how participants respond to the entrance fee system by looking at their available options to spend leisure time when living in an area with limited financial resources and recreational facilities. Using qualitative data collected in Northwest Arkansas (NWA), this study looks at how the transformation of JCF from a public to quasi-public space redefines relations …

Effect Of Nitrogen Fertilizer Rates And Two-Spotted Spider Mite Incidence On 'Strawberry Festival' Strawberry Cultivar Performance, Megan E. Mcgovern

Graduate Theses and Dissertations

The decline in strawberry (Fragaria x ananassa Duch.) production in Arkansas over the last 50 years has sparked an interest in the use of season extension techniques to improve yield and fruit quality. High tunnel strawberry production has the potential to become a profitable and sustainable production system; however, information on nutrient and pest management is limited.

The overall objective of this study was to determine the response of ‘St. Festival’ strawberry cultivar to different nitrogen fertilizer rates in order to develop a fertilization program for strawberries grown under high tunnel production systems. Experiments were conducted at the University of …

Economic Literacy: Measuring The Economic Human Capital Of Arkansas K-12 Teachers, June Marie Freund

Graduate Theses and Dissertations

Economic literacy is recognized as a deficit quality in the United States, no more prevalent than during the last great recession. It is paramount the K-12 educational system lead the movement to educate the public on economic content and issues, as it is the one institution that has direct contact with all citizens. The question then must be asked, how economic literate are teachers entrusted with the responsibility of imparting economic knowledge to his/her K-12 grade level student. A sample of Arkansas teachers at each grade level K – 12 were tested using national normed economic literacy tests designed to …

Reducing Nutrient Runoff From Poultry Production Facilities Using Locally-Sourced Iron And Aluminum Byproducts, Sheri Lynn Herron

Graduate Theses and Dissertations

Phosphorus (P) inputs to fresh waters can accelerate the eutrophication process. Agricultural nutrient runoff has been shown to be a contributor of P and nitrogen (N). Broiler production areas were evaluated for their potential to contribute P and N to runoff. Broiler house dust (BHD) samples were analyzed and compared to broiler litter (BL), rainfall simulations were conducted on plots adjacent to broiler house fans to evaluate nutrient enrichment in runoff from deposited dust, and runoff was automatically sampled at two culverts draining the land around broiler houses. Following this, an on-farm byproduct containment and nutrient removal structure was designed …

Lidar And Machine Learning Estimation Of Hardwood Forest Biomass In Mountainous And Bottomland Environments, Bowei Xue

Graduate Theses and Dissertations

Light detection and ranging (lidar) has been applied in various forest applications, such as to retrieve forest structural information, to build statistical models for identification of tree species, and to monitor forest growth. However, despite significant progress in these areas, the choice of regression approach and parameter tuning remains an ongoing critical question. This study focused on choosing the right spatial generalization level to transform lidar point clouds to 2D images which can be further processed by mature image processing and pattern recognition approaches. It also compared the prediction ability of popular machine learning algorithms applied to aboveground forest biomass …

Stable Isotopes As A Tool To Characterize Carbon Cycling And Develop Hydrologic Budgets In Mantled Karst Settings, Katherine Knierim

Graduate Theses and Dissertations

Isotopes of water (δ2H/δ18O), carbon dioxide (δ13C-CO2), and dissolved inorganic carbon (δ13C-DIC) were used to explore water quality, trace carbon cycling, and quantify recharge sources through mantled karst and into Blowing Spring Cave (BSC). Of the possible sources of contamination in the BSC recharge area, septic-tank effluent was hypothesized to degrade water quality at the spring outlet of BSC because of the dominance of septic tanks for waste treatment, unsuitable topography and soil for septic-tank absorption fields, increased nitrate and chloride concentrations concomitant with increased urbanization, and increased Escherichia coli with discharge. Carbon cycling between the soil and BSC was …

Aerial Thermography In Archaeological Prospection: Applications & Processing, Autumn Chrysantha Cool

Graduate Theses and Dissertations

Aerial thermography is one of the least utilized archaeological prospection methods, yet it has great potential for detecting anthropogenic anomalies. Thermal infrared radiation is absorbed and reemitted at varying rates by all objects on and within the ground depending upon their density, composition, and moisture content. If an area containing archaeological features is recorded at the moment when their thermal signatures most strongly contrast with that of the surrounding matrix, they can be visually identified in thermal images.

Research conducted in the 1960s and 1970s established a few basic rules for conducting thermal survey, but the expense associated with the …

Impact Of Professional Learning Community Design On Teacher Instruction, Carol Jeanette Turner

Graduate Theses and Dissertations

This descriptive case study closely examined a professional learning community in an Arkansas middle school. The site was selected because the school was removed from the state's school improvement list after implementing professional learning communities. The purpose of the study was to determine how the design of a professional learning community impacts teacher instruction in a middle school setting. The literature reviewed included historical perspective, definitions and characteristics of professional learning communities, teacher professional development, and teacher effect on student achievement. Eight teachers, one principal, and one instructional facilitator were interviewed about the professional learning communities in their school. The …
