Characterizing The Utility Of Atonik On Improving Rice Response To Herbicides, Srikanth Kumar Karaikal May 2023

Characterizing The Utility Of Atonik On Improving Rice Response To Herbicides, Srikanth Kumar Karaikal

Graduate Theses and Dissertations

Biostimulants can improve plant tolerance to abiotic stress by improving plant growth and development. Herbicides cause abiotic stress to crops shortly after application, which may affect yield. Preliminary tests showed that rice yield benefits from Atonik seed treatment or tank-mixture of Atonik with foliar herbicides. Experiments were conducted in the field and greenhouse to: (1) determine if seed treatment with Atonik improves rice tolerance to pre-plant herbicides; (2 and 3) evaluate the effect of Atonik seed treatment on rice response to pre-emergence and delayed pre-emergence herbicides; and (4) determine if Atonik improves crop safety of foliar-applied herbicides. Field studies were …

Ecological, Evolutionary, And Temporal Dynamics Of Animal Mortality Events, Simon Patrick Tye May 2023

Ecological, Evolutionary, And Temporal Dynamics Of Animal Mortality Events, Simon Patrick Tye

Graduate Theses and Dissertations

Global declines of animal abundances are emblematic of the Anthropocene. Recent animal declines have increasingly involved more frequent and intense die-offs within populations, or mass mortality events (MMEs). These extreme demographic events can lead to rapid changes in biological communities, either by imperiling the affected population or influencing populations remaining within communities. To date, there is still limited information about the effects of predator MMEs on immediate ecological dynamics within communities and rapid evolutionary dynamics within remaining populations that may ensue. Moreover, few approaches exist to predict future occurrences of predator MMEs across broad spatial scales. To address these gaps, …


Cartographic Analysis Of Earth-Sun Relationships In Ancient Amazonia, Jackson Bennett Critser May 2023

Cartographic Analysis Of Earth-Sun Relationships In Ancient Amazonia, Jackson Bennett Critser

Graduate Theses and Dissertations

The alignments of ancient man-made earthworks across the Amazon Basin, known as geoglyphs, have recently been discovered to predate early societal dates. Although much research indicated that the Amazon was uninhabitable until the last 1000 years (Meggers 1971), new evidence suggests this is not the case. The application of advanced cartographic and GIS technologies were implemented to link solar ‘marker’ days (e.g. solstices, equinoxes) with the alignment of geoglyphs, megaliths, stone architecture, and broader city forms to discover and analyze previously unknown Earth-Sun relationships across the Amazon Basin to conceivably sophisticated urban and architectural plans. The study of these geoglyphs …


The Role Of Partisan Politics On Support For Public Institutions Of Higher Education, Jason G. Ramage May 2023

The Role Of Partisan Politics On Support For Public Institutions Of Higher Education, Jason G. Ramage

Graduate Theses and Dissertations

Over several decades, a greater share of the expense of earning a college degree has shifted to students and their families as appropriations to public institutions of higher education have declined as a percentage of the overall cost to educate a student. Tuition has greatly outpaced inflation during this period, while inflation-adjusted household income has remained relatively flat. Despite all the benefits that accrue to both the college graduate and society as a whole, for the less affluent, a college education is becoming increasingly difficult to attain. Many decide the financial barriers are simply too great and elect not to …


The Terroir Of Swiss Cheese: A Temporal And Geomorphological Investigation Of The Martian Co2 Sublimation Pits, Racine D. Cleveland May 2023

The Terroir Of Swiss Cheese: A Temporal And Geomorphological Investigation Of The Martian Co2 Sublimation Pits, Racine D. Cleveland

Graduate Theses and Dissertations

Observations by NASA Mars Global Surveyor showed evidence of rough topography on the South Pole of Mars. The topography is the result of CO2 sublimation processes that occur through the changing seasons on the red planet. These sublimation areas are known to scientists as Swiss Cheese Features (SCF). SCF are erosional degradation pits that have been studied for over two decades. Studies show that these SCF increase in area over time, but these values are collected by hand on a per feature basis. Models for the pit evolution have also played a part in understanding these SCF. This work is …


A Public Policy Approach To Life After Service For U.S. Military Veterans: Mental Health, Homelessness, And Reintegration, Eric D. Button May 2023

A Public Policy Approach To Life After Service For U.S. Military Veterans: Mental Health, Homelessness, And Reintegration, Eric D. Button

Graduate Theses and Dissertations

This dissertation, through a public policy lens, examines life after U.S. military service as it relates to reintegration, the ability of state-level veteran-specific mental health programs to address veterans’ mental health challenges, and states’ ability to address veteran homelessness. First, I use 2019 Centers for Disease Control and Prevention (CDC) Behavioral Risk Factors Surveillance Survey data, along with various measures of state-level characteristics, to examine the influence of relevant state-level policies on veterans’ mental health outcomes. Based on multi-level modeling results, findings suggest that the presence of at least one state-level veteran specific mental health program may be a mitigating …


An Ecological Perspective Of American Rodent-Borne Orthohantavirus Surveillance, Nathaniel Mull May 2023

An Ecological Perspective Of American Rodent-Borne Orthohantavirus Surveillance, Nathaniel Mull

Graduate Theses and Dissertations

Orthohantaviruses are a global group of viruses found primarily in rodents, though several viruses have also been found in shrews and moles. Many rodent-borne orthohantaviruses are capable of causing one of several diseases in humans, and the mortality associated with these diseases ranges from < 0.1% - 50% depending on the specific etiological virus. In North and South America, orthohantavirus research was ignited by an outbreak of severe disease in the Four Corners region of the United States in 1993. However, despite the discovery of over 20 orthohantaviruses in the Americas, our understanding of orthohantavirus ecology and virus-host dynamics in this region is still limited, and orthohantavirus surveillance is generally restricted in scope to select regions and small portions of host distributional ranges. In Chapter I, I present a literature review on the current understanding of American rodent-borne orthohantavirus ecology. This review focused on under-studied orthohantaviruses, addressing gaps in knowledge by extrapolating information from well-studied orthohantaviruses, general rodent ecology, and occassionally from Eurasian orthohantavirus-host ecology. There were several key conclusions generated from this review that warrant further research: 1) the large number of putative orthohantaviruses and gaps in orthohantavirus evolution necessitate further surveillance and characterization, 2) orthohantavirus traits differ and are more generalizable based on host taxonomy rather than geography, and 3) orthohantavirus host species are disproportionately found in grasslands and disturbed habitats. In Chapter II, I present a prioritized list of rodent species to target for orthohantavirus surveillance based on predictive modeling using machine learning. Probable orthohantavirus hosts were predicted based on traits of known orthohantavirus hosts using two different types of evidence: RT-PCR and virus isolation. Predicted host distributions were also mapped to identify geographic hotspots to spatially guide future surveillance efforts. In Chapter III, I present a framework for understanding and predicting orthohantavirus traits based on reservoir host phylogeny, as opposed to the traditional geographic dichotomy used to group orthohantaviruses. This framework establishes three distinct orthohantavirus groups: murid-borne orthohantaviruses, arvicoline-borne orthohantaviruses, and non-arvicoline cricetid-borne orthohantaviruses, which differ in several key traits, including the human disease they cause, transmission routes, and virus-host fidelity. In Chapter IV, I compare rodent communities and orthohantavirus prevalence among grassland management regimes. Sites that were periodically burned had high rodent diversity and a high proportion of grassland species. However, rodent seroprevalence for orthohantavirus was also highest in burned sites, representing a trade-off in habitat management outcomes. The high seroprevalence in burned sites is likely due to the robust populations supported by the high quality habitat resulting from prescribed burning. In Chapters V and VI, I describe Ozark virus and Sager Creek virus, two novel orthohantaviruses discovered from specimens collected during Chapter IV. Both chapters report full genome sequences of the respective viruses and compare both nucleotide and protein phylogenies with related orthohantaviruses. Additionally in Chapter VI, I support the genetic analyses with molecular and ecological characterizations, including seasonal fluctuations in host abundance, correlates of prevalence, evidence of virus shedding, and information on host cell susceptibility to Sager Creek virus.


Factors That Affect Home Range Of Timber Rattlesnakes (Crotalus Horridus) In Northwest Arkansas, Bannon Gallaher May 2023

Factors That Affect Home Range Of Timber Rattlesnakes (Crotalus Horridus) In Northwest Arkansas, Bannon Gallaher

Graduate Theses and Dissertations

Conservation of animal populations requires knowledge of their habitat and spatial needs. Quantifying spatial requirements involves the analysis of home range. We examined the effects of sex, body size (SVL), body condition (log mass/log SVL), and year on home range in Timber Rattlesnakes (Crotalus horridus) in Northwest Arkansas. Individual locality data from an ongoing, 22+ year radio-telemetry study in Madison Co., Arkansas were analyzed using both minimum convex polygon (MCP) and Kernel Density Estimates (KDE). Plots of the number of sequential observations versus home range (MCP and KDE) determined that a minimum of 25 locations per individual per active season …


Readiness To Lead: Novice School Leaders' Perceptions Of The Impact Arkansas Fellowship Experience On Their Preparedness To Assume School Leadership Roles, Allison Prewitt May 2023

Readiness To Lead: Novice School Leaders' Perceptions Of The Impact Arkansas Fellowship Experience On Their Preparedness To Assume School Leadership Roles, Allison Prewitt

Graduate Theses and Dissertations

Research provides increasing evidence that school leadership correlates with school performance (Herman et al., 2016). The leadership skills of K-12 school administrators are linked with student achievement. Evidence indicates that school leaders’ roles continue to evolve as accountability measures change (Grissom et al., 2021). Historically, principal preparation programs emphasized developing management skills. According to research, this is insufficient to prepare instructional leaders for the complex social context of contemporary education (Hernandez et al., 2012; Kerston, 2010; Levine, 2005; Lynch, 2012; Miller, 2013; Zubnzycki, 2013). Unfortunately, most principal preparation programs (PPPs) have not kept pace with the expanding role of principals …


Freedom, Abortion, And Hypocrisy: The Effect Of Hypocrisy On Pro-Life Abortion Attitudes, Emily M. Vance May 2023

Freedom, Abortion, And Hypocrisy: The Effect Of Hypocrisy On Pro-Life Abortion Attitudes, Emily M. Vance

Graduate Theses and Dissertations

Previous research suggests that highlighting the gap between inconsistent values can result in long-term attitude change (Rokeach, 1971), that feeling hypocritical might prompt pro-attitudinal behavior (e.g., Dickerson et al., 1992), and that a reactance decoy makes participants more receptive to subsequent persuasive messages (Schumpe et al., 2020). Drawing from these findings, the purpose of the present study was to investigate whether the impact of induced hypocrisy on pro-life abortion attitudes, an attitude commonly grounded in the value of freedom, depended on a reactance decoy. Consistent with Aronson et al.’s paradigm (1991), participants first publicly advocated for the importance of personal …

A vision for the future included senior leader’s perspectives on three elements of the university: the university’s mission and purpose, academics, and student services. Their experience in higher education combined with their …


Effects Of Landscape And Yard Features On Mammals In Residential Yards In Northwest Arkansas, Emily Johansson May 2023

Effects Of Landscape And Yard Features On Mammals In Residential Yards In Northwest Arkansas, Emily Johansson

Graduate Theses and Dissertations

The human footprint is rapidly expanding, and wildlife habitat is continuously being converted to human residential properties. Most wildlife residing in developing areas are displaced to nearby undeveloped areas. However, some animals can coexist with humans and acquire the necessary resources (food, water, shelter) within the human environment. This may be particularly true when development is low intensity, as in suburban yards. Due to the wide variety in how homeowners utilize their yards, they can be considered individually managed “greenspaces.” These yards can provide a range of food (e.g., bird feeders, compost, gardens), water (bird baths and garden ponds), and …


A Narrative Research Study On How Brazilian Women Executives Build A Sense Of Community And Belonging When Transferred To The United States, Silvia Regina Siqueira May 2023

A Narrative Research Study On How Brazilian Women Executives Build A Sense Of Community And Belonging When Transferred To The United States, Silvia Regina Siqueira

Graduate Theses and Dissertations

According to the American Immigration Council (2021), 14 percent of the United States population is foreign-born. Immigrants have enriched American culture and enhanced our influence in the world. People feel a need to belong and have an inherent desire for deep, lasting, and meaningful connections (Baumeister & Leary, 1995). Research suggests that humans are fundamentally and pervasively motivated by a need to belong and the desire to form and maintain enduring interpersonal attachments (Allen, Kern, Rozek, McInerney & George, 2021). These authors also define immigrants’ sense of belonging in terms of how they make sense of their social identification with …


Biology, Monitoring, Sampling, And Management Of Rice Billbug, Sphenophorus Pertinax, In Furrow-Irrigated Rice, Chase Alan Floyd Dec 2022

Biology, Monitoring, Sampling, And Management Of Rice Billbug, Sphenophorus Pertinax, In Furrow-Irrigated Rice, Chase Alan Floyd

Graduate Theses and Dissertations

Furrow-irrigated rice hectares have increased annually for the last five years in the predominant long-grain rice producing states. Initial implementation of the system began in the 1980’s, but lack of rice blast (Magnaporthe grisea, Hebert) resistant cultivars made the system a nonviable option for rice producers. Hybridization of rice cultivars with less susceptibility has begun to increase the interest of producers to implement a furrow-irrigated rice production system due to the cost saving opportunities that it may provide. Elimination of the flood from large sections of the rice fields in a furrow-irrigated system alters management strategies and pest complexes compared …


Dream Border, Pardis Ahmadpour Mobarake Dec 2022

Dream Border, Pardis Ahmadpour Mobarake

Graduate Theses and Dissertations

Dream Border is the result of my lived experience of relocation. The exhibition addresses the duality of being on the border between reality and imagination. In this place, the present, past, and future exist simultaneously. By engaging with personal narratives, childhood memories, as well as Iranian cultural and literary visual elements, I search for universal concepts in relocation. These works evoke the imposition of power and the many phenomena that the contemporary world endures despite globalization, such as anxiety, fear, and oppression on a small or large scale, which compel people to relocate. Uncertainty in the process of migration and …

The first chapter developed a baseline of past and current flood inventory in Panama, which required the use of flood historical data, thematic cartography, and Geographic Information Science (GIS). This chapter shows Panama has experienced floods in varying degrees. Through the spatial and temporal distribution of floods from …


Interfacial Engineering Of Nickel-Rich Layered Oxide Cathodes Via Atomic Layer Deposition (Ald), Xin Wang Dec 2022

Interfacial Engineering Of Nickel-Rich Layered Oxide Cathodes Via Atomic Layer Deposition (Ald), Xin Wang

Graduate Theses and Dissertations

Layered nickel-rich cathodes LiNixMnyCozO2 (NMCs, x + y + z =1, x ≥ 0.6) are regarded as one of the most promising cathode materials for next-generation lithium-ion batteries (LIBs), given their remarkably reduced cost and increased capacity compared to the conventional LiCoO2 cathode. However, the deployment of these Ni-rich cathodes has been hindered by the continuous loss of practical capacity and reduction in average working voltage, inherently due to their interfacial, structural, and thermodynamic instability. To address these issues, interfacial engineering via surface modification has been well-recognized as an effective strategy and a large number of coating materials have been …


Improving Building Cfd Peak Pressure Computation Using Les With A Focus On Inflow Turbulence Methods And Grid Spacing Size., Zahra Mansouri Dec 2022

Improving Building Cfd Peak Pressure Computation Using Les With A Focus On Inflow Turbulence Methods And Grid Spacing Size., Zahra Mansouri

Graduate Theses and Dissertations

Structural failures by extreme winds often leads to economic losses and even deaths. Proper design of buildings requires accurate estimation of wind loads to prevent structural damage. Using routine guidelines generally leads to the underestimation of buildings’ peak pressures, in which most failures occur. To estimate wind loads more accurately three different methods (i.e., field measurement, wind tunnel (WT), and computational fluid dynamics (CFD)) are in use. A well-validated CFD provides more flow field details at lower costs compared to field measurements and WT. As strong winds are extremely turbulent, the effects of turbulence in wind should be incorporated into …

The Evolution Of X-Ray Binaries And Their Accretion States, Lacey A. West Dec 2022

The Evolution Of X-Ray Binaries And Their Accretion States, Lacey A. West

Graduate Theses and Dissertations

X-ray binary systems (XRBs) consist of a compact object component (e.g., black hole or neutron star) that accretes matter from a companion star. Although the extent to which XRBs contributed to the early heating of the intergalactic medium is still under investigation, it is estimated that XRBs dominated the X-ray radiation field before the reionization epoch. The study of XRB emission is therefore crucial to our understanding of the very early universe. Furthermore, studying the abundance and radial distribution of each XRB type within a galaxy can be revealing of the host galaxy’s local properties, structure, and evolution. XRB spectra …


Movie Reviews Sentiment Analysis Using Bert, Gibson Nkhata Dec 2022

Movie Reviews Sentiment Analysis Using Bert, Gibson Nkhata

Graduate Theses and Dissertations

Sentiment analysis (SA) or opinion mining is analysis of emotions and opinions from texts. It is one of the active research areas in Natural Language Processing (NLP). Various approaches have been deployed in the literature to address the problem. These techniques devise complex and sophisticated frameworks in order to attain optimal accuracy with their focus on polarity classification or binary classification. In this paper, we aim to fine-tune BERT in a simple but robust approach for movie reviews sentiment analysis to provide better accuracy than state-of-the-art (SOTA) methods. We start by conducting sentiment classification for every review, followed by computing …

The Internal Debate: How National Identity Created The Russo-Ukrainian Conflict, Logan James Weisenfels

Graduate Theses and Dissertations

The longstanding conflict in Ukraine has prompted more attention, discussion, and research into the relationship between Ukraine and Russia. This relationship dates back to medieval times, but its importance to contemporary issues begins in the 19-20th Centuries and come to a head after the fall of the Soviet Union. This analysis seeks to understand how and why Ukrainian national identity gradually became a solidified civic identity after the Maiden Revolution and annexation of Crimea in 2014. This starts with providing a short history between Russia and Ukraine, that looks at certain events and regions in their shared history, and are …


Enhancing Human Schwann Cells Reparative Behavior Using Heparin/Collagen Layer-By-Layer Coatings, Luis Carlos Pinzon-Herrera Dec 2022

Enhancing Human Schwann Cells Reparative Behavior Using Heparin/Collagen Layer-By-Layer Coatings, Luis Carlos Pinzon-Herrera

Graduate Theses and Dissertations

When a peripheral nerve injury (PNI) occurs, the gold standard for tissue regeneration is the use of autografts. However, due to the secondary effects produced by multiple surgeries involved in the removal and implantation of autografts for very small lesions, it is possible to replace them with the use of Nerve Guide Conduits (NGCs). However, NGCs are limited to short lesions (less than 1 cm). This limitation is caused by the absence of compounds in the extracellular matrix (ECM) that autografts can provide. Since much of the regenerative process takes place on the NGC surface, our work aims to modify …

A Case Study Examining Women In Leadership At A College Of Osteopathic Medicine, Sloane Gibson Kelley Dec 2022

A Case Study Examining Women In Leadership At A College Of Osteopathic Medicine, Sloane Gibson Kelley

Graduate Theses and Dissertations

Dr. Andrew Taylor Still, the founder of osteopathic medicine, actively promoted gender parity in the field from its inception, at a time when few medical schools accepted women into their programs, and even fewer all-female medical schools existed (Quinn, 2017; Simpson & Weiser, 1996). Although an almost equal number of male and female students are enrolled in osteopathic medical schools, men far outnumber women in positions of leadership. While the data for the number of women deans and department chairs at osteopathic medical schools does not exist, research by the Association of American Medical Colleges (2021) showed that 24% of …
