Human-Bat Interactions In A Disease Emergence Hotspot: Implications For Human Health And Bat Conservation, Reilly Tempest Jackson
Human-Bat Interactions In A Disease Emergence Hotspot: Implications For Human Health And Bat Conservation, Reilly Tempest Jackson
Graduate Theses and Dissertations
Bats are an ecologically important taxon that can host zoonotic pathogens. Globally, many bat species are synanthropic and live closely with humans, often roosting in man-made structures. The spatial overlap between humans and bats creates opportunities for human-bat contact, which can lead to human exposure to bat-borne pathogens and conflicts that cause bat mortality. Despite this risk, little is known about the drivers and characteristics of these human-bat interactions in buildings and work is needed to understand this aspect of the wildlife-urban interface. In Chapter I, I present a literature review that identifies the geographic and taxonomic trends in reported …

Evaluating Garment Fit Perception For Pregnant Women During 1st, 2nd, Or 3rd Trimesters, Nelima Zipporah Barasa
Graduate Theses and Dissertations
During pregnancy, women experience diverse physical body changes as the pregnancy progresses through different periods. It has been noted that anthropometric changes occur during pregnancy in a non-linear manner and can be measured using 3D body scanners at various stages of pregnancy. The changes are diverse, and impact pregnant women's garment fit differently as the pregnancy progresses through each trimester. Pregnant women have experience in dressing their pre-pregnant bodies in stylish garments and would similarly want to dress fashionably when pregnant. This has led to the need for garments that can accommodate body changes comfortably and fashionably without losing the …
Age, Size, And Composition Of Selected Old-Growth Shortleaf Pine Stands In The Upper Buffalo River, Arkansas, Willa Avery Thomason
Age, Size, And Composition Of Selected Old-Growth Shortleaf Pine Stands In The Upper Buffalo River, Arkansas, Willa Avery Thomason
Graduate Theses and Dissertations
Shortleaf pine (Pinus echinata) approaches the westernmost limits of its range in the Arkansas Ozarks. Despite heavy logging of shortleaf pine throughout its range during the 19th and 20th centuries, the species was not easily accessible for harvest and transportation in the most rugged areas of the Boston Mountains and, as a result, there are a few extant stands of old-growth shortleaf pine in the region. The shortleaf pine stands in the interior Boston Mountains are unusual in that they exist primarily above bluff lines at topographic breaks in the hardwood canopy and are not disturbed by fire as frequently …

When proteins aggregate to form amyloid fibers, the secondary structure of the protein converts from its native state to a cross-beta-sheet. Fibroblast growth factors (FGFs) possess an essential role in neuronal survival during development. In addition, they are involved in neural stem cell (NSC) proliferation. Fibroblast growth factors (FGFs) are well known to be synthesized in the central nervous system (CNS) and …
Adoption And Continued Use Of Irrigation Management Practices In Arkansas, Evelyn Osei
Adoption And Continued Use Of Irrigation Management Practices In Arkansas, Evelyn Osei
Graduate Theses and Dissertations
The paper assesses row crop producers continued use of irrigation management practices, namely the decision to continue rather than stop the use of irrigation practices, using a probit with a sample selection model. To better explain and increase user acceptance, we must understand why producers adopt and continue using irrigation management practices. Past studies have researched the adoption of management practices. However, it is also essential to consider what factors influence continued use and why producers discontinue irrigation practices after adoption. This is the first study to investigate factors influencing the continued use of irrigation management practices in Arkansas. Producers …
Habitat Associations Of Plains Spotted Skunk (Spilogale Interrupta) Across The Plains Ecoregion. And The Landcover Occupancy Models Of The Gray Fox (Urocyon Cinereoargenteus) In The Southeastern Plains Region In Arkansas, Michael Shaw
Graduate Theses and Dissertations
Much of the landscape of the United States has been altered by humans, leading to the eradication of most populations of large mammalian predators. Consequently, many species of mammalian mesopredators (medium-sized mammalian predators) have come to dominate the landscape. Species such as the gray fox (Urocyon cinereoargenteus) may appear to be on the rise and doing well due to their widespread range, but at a local scale may need monitoring and less is known in areas of its range. Others such as the plains spotted skunk have a wide range across the plains but are on the decline even with …

By harnessing energy from the surrounding environment, such as solar, thermal, vibrational, or RF sources, these sensors can potentially operate …
The Study Of The Polarization Domains Of Mbe-Grown Barium Titanate Thin Films And Nanodots Using Pfm, Mohammad Zamani-Alavijeh
The Study Of The Polarization Domains Of Mbe-Grown Barium Titanate Thin Films And Nanodots Using Pfm, Mohammad Zamani-Alavijeh
Graduate Theses and Dissertations
Polarization domains are the fundamental elements in ferroelectric materials that contribute to their properties. A natural polarization domain, which possesses a specific polarization direction or state, typically ranges in size from one unit cell to a few micrometers. Therefore, studying polarization domains requires the fabrication of materials and the measurement of ferroelectric properties at the nanoscale. In this study, molecular beam epitaxy (MBE) is employed to fabricate barium titanate (BTO) crystals, and piezoresponse force microscopy (PFM) is used to measure the properties of polarization domains at the nanoscale. In the beginning, this study identifies the reflection of high-energy electron diffraction …
Theistic Open Futurism: A Critical Philosophical Investigation, Elijah Hess
Theistic Open Futurism: A Critical Philosophical Investigation, Elijah Hess
Graduate Theses and Dissertations
In this dissertation I critically evaluate and develop a model of God I dub “theistic open futurism”—the view that an omniscient, omnipotent, and omnibenevolent being exists but fails to know future contingent statements because such statements are not true. Contrary to what their free will critics have supposed, I argue that theistic open futurists do not subscribe to a metaphysical vision of the future that is logically or religiously incoherent. With respect to the latter, I suggest that while some open theists have overstated their case concerning the amount of providential control God could have given the reality of an …

Assessment Of Dietary Energy And Amino Acid Diet Formulation In The Modern Broilers, Matheus Freitas Costa
Assessment Of Dietary Energy And Amino Acid Diet Formulation In The Modern Broilers, Matheus Freitas Costa
Graduate Theses and Dissertations
As a result of the advancement of genetics, understanding broiler requirements for dietary energy and amino acids is essential for improving live performance and carcass characteristics. The energy system used to formulate diets in poultry is based on metabolizable energy (ME); this equation can be described as the total amount of energy in the feed minus gases and feces. However, the net energy (NE) system may be the best depiction of the energy utilized by birds for production and maintenance purposes once the heat increment (HI) is measured. Thus, a series of studies were conducted to establish the responsiveness of …
Trojan Detection Expansion Of Structural Checking, Zachary Chapman
Trojan Detection Expansion Of Structural Checking, Zachary Chapman
Graduate Theses and Dissertations
With the growth of the integrated circuit (IC) market, there has also been a rise in demand for third-party soft intellectual properties (IPs). However, the growing use of such Ips makes it easier for adversaries to hide malicious code, like hardware Trojans, into these designs. Unlike software Trojan detection, hardware Trojan detection is still an active research area. One proposed approach to this problem is the Structural Checking tool, which can detect hardware Trojans using two methodologies. The first method is a matching process, which takes an unknown design and attempts to determine if it might contain a Trojan by …
The Effects Of Diet, Size, And Phylogeny On Primate Dental Proportions, Rudolph J. Wilkins
The Effects Of Diet, Size, And Phylogeny On Primate Dental Proportions, Rudolph J. Wilkins
Graduate Theses and Dissertations
It is generally appreciated that there is a relationship between the relative size of the incisors, mandible length, and diet in primates. More specifically, the differences in relative incisor size among primate species are believed to be evolutionary adaptations to their use during food processing and acquisition. While this satisfactorily explains relatively large incisors, it fails to address the relatively small incisor size seen in many taxa. One hypothesis is that there is a trade-off between molar size and incisor size in species with relatively short mandibles. The following study uses two-way ANOVA to evaluate the possibility that spatial constraint …

Determination Of P Availability In Feedstuffs And The Effect Of Feedstuffs And Anti-Nutritional Factors On Secretory Iga Production And Host Nutrient Losses In Poultry, Benjamin Parsons
Graduate Theses and Dissertations
The availability of P in feedstuffs and the effect of feedstuffs, feed additives, and anti-nutritional factors on secretory IgA (sIgA) production in chickens were evaluated. A rapid method was developed using the precision-fed rooster assay to evaluate phytic acid disappearance, P digestibility, and phytase efficacy. Further, exogenous phytase was found to be effective at degrading myo-inositol 1,2,3,4,5,6-hexakis, however, the enzyme was less efficient at P release from lower inositol phosphates. The availability of P in feedstuffs was found to be affected by dietary Ca content, where increasing Ca linearly reduced (P < 0.05) both phytic acid hydrolysis and P digestibility. For example, the standardized ileal digestibility of P was reduced from 73 to 47% in soybean meal when the dietary Ca content was increased from 0.30 to 0.75%. The digestibility of P in distillers dried grains with solubles (DDGS) and corn fermented protein (CFP), however, was high across all Ca levels (71 to 80%). Relative P bioavailability based on tibia bone ash was also found to be high for DDGS and CFP, being 81 and 78%, respectively. Upon further evaluation, it was observed that utilizing low dietary Ca levels (0.30%) when P digestibility in individual plant-based feedstuffs was determined overestimated the P digestibility in practical grower diets by up to 16 percentage units. Utilization of higher Ca levels (0.75%) when P digestibility in individual plant-based feedstuffs was determined, however, resulted in calcualted P digestibility values that were within 1 to 3 percentage units of the measured digestibility in practical grower diets. Aside from P, feedstuffs were also evaluated to determine their effect on sIgA production in the intestine. Roosters excreted approximately 6 to 30 mg of sIgA / 24 h. Further, the proportional contribution of sIgA to total endogenous amino acid (AA) losses ranged from 1 to 13%, with the greatest contribution being observed for Trp. The addition of casein to a protein-free diet increased (P < 0.05) sIgA production in both roosters and broiler chickens. There was no change (P > 0.05) in sIgA production compared with the protein-free diet …
Examining Task-Related Differences In The Error-Related Negativity (Ern) As A Function Of Cognitive Control Strategy And Trait Anxiety, Russell Mach
Graduate Theses and Dissertations
Anxiety disorders pose a significant challenge to daily living, workplace productivity, and healthcare systems. Extant research supports empirical links between anxiety and brain-level error monitoring. The ERN – or error-related negativity – is one widely studied correlate of anxious symptomatology. Relatively stable individual differences in the ERN are inferred from electroencephalogram (EEG) recordings time-locked to the commission of mistakes. However, the assumed interchangeability of ERNs elicited under different experimental conditions has not been thoroughly evaluated. Canonical tasks for measuring the ERN may cue specific strategies for cognitive control, possibly producing divergent findings across studies. In a sample of 108 undergraduate …
A Study Of Latino Undergraduate Students In Retention Cohorts At The University Of Arkansas, Ramon Balderas
A Study Of Latino Undergraduate Students In Retention Cohorts At The University Of Arkansas, Ramon Balderas
Graduate Theses and Dissertations
Higher education institutions do not have a history of being racially inclusive, and as a result, research and best practices around retention and student success have not been developed for underrepresented and minoritized students. Although there has been a surge in scholarship on diversifying higher education, literature, and identifying best practices focused on retaining students there is less research and literature that looks at Latino students. The study's purpose was to better understand Latino undergraduate student retention patterns at the University of Arkansas, a midwestern public four-year research university. The significance of the study was to assist UA administrators and …
Characterization Of Human Fibroblast Growth Factor 2 Variant To Determine Effects On Structure, Stability, And Cell Proliferation, Ryan Layes
Graduate Theses and Dissertations
Fibroblast growth factors (FGFs) are a family of cell signaling proteins conserved across multiple species. Each individual FGF elicits different cellular functions including, but not limited to, proliferation, migration, differentiation, angiogenesis, and wound healing. One of the most studied members, fibroblast growth factor 2 (FGF2), has demonstrated substantial wound healing capacity in a wide range of tissues including skeletal, muscular, neural, respiratory, epithelial, and cardiovascular. This ability makes FGF2 a potential therapeutic for a wide range of conditions and injuries. However, due to a short half-life at room temperature, therapeutic use of FGF2 is limited. It has been demonstrated that …
Verification Of Astm Centrifugation Equations For Soil Suction Determination, Esteban Maclein Miranda Pinzon
Verification Of Astm Centrifugation Equations For Soil Suction Determination, Esteban Maclein Miranda Pinzon
Graduate Theses and Dissertations
The unit correction constant (B) in the ASTM D6836 standard needs to be evaluated. The B-value was proposed to be 0.00548 instead of 0.00553. This apparent discrepancy led to an investigation comparing the predicted and measured suction values for high air entry (HAE) ceramic disks. A Beckman-Coulter Model J6-MI six-bay centrifuge and a WP4C Dewpoint Potentiameter were used in the testing program. HAE ceramic disks rated with bubbling pressures of 3-bar and 5-bar were used as analogue soil specimens. The HAE ceramic disks were spun in the small-scale centrifuge to apply prescribed suction amounts and then placed in the WP4C …
Estimation Of Gross Primary Productivity Of Rice In Arkansas Using The Vegetation Photosynthesis Model, Riasad Bin Mahbub
Estimation Of Gross Primary Productivity Of Rice In Arkansas Using The Vegetation Photosynthesis Model, Riasad Bin Mahbub
Graduate Theses and Dissertations
An estimate of the gross primary productivity (GPP) of rice fields can be instrumental to understand their harvest yield and to fulfill an array of agricultural monitoring needs. One of the most common satellite-based models to estimate GPP is the vegetation photosynthesis model (VPM). In this study, we use the VPM model for rice cropland in Arkansas and validate our findings against 16 site-years in-situ data (eddy covariance (EC)). At the site scale, results validated against 16 site-years have shown that the VPM with site information (R2 = 0.71, MAE = 2.90 g C m-2day- 1, and RMSE = 4.04 …

This study explores the key factors that drive milk producers to enter the milk market as sellers in Kyrgyzstan. The study utilizes the Life in Kyrgyzstan dataset, a nationally representative survey that tracks 3,000 households and 8,000 individuals throughout Kyrgyzstan. The results were analyzed with two different models: Heckman’s two-stage and the double hurdle models. The results show that regional location, ethnic group origin, risk awareness, dependency ratio, vehicle ownership, total value of assets, distance to agro market, and family shock occurrence significantly impact both market participation and the volume of milk sales. The findings hold great significance in establishing …
Explicit And Implicit Measurements Of Sensory And Emotional Responses To Stimuli In Children With Autism Spectrum Disorder, Asmita Singh
Explicit And Implicit Measurements Of Sensory And Emotional Responses To Stimuli In Children With Autism Spectrum Disorder, Asmita Singh
Graduate Theses and Dissertations
Autism Spectrum Disorder (ASD) is a developmental disability that causes significant social, communication, and behavioral challenges and it is often involved in sensory processing issues that lead to feeding problems. While our understanding of how sensory responses differ in people with ASD is limited, past studies indicated atypical responses to certain stimuli. If these stimuli can be identified, they could be good indicators to identify the risk of autism in young children. The main objective of this dissertation was to identify a specific stimulus leading autistic children to exhibit atypical responses in terms of sensory or emotional aspects. Children between …
Index Fund Ownership And Stock Price Efficiency: Evidence From Quarterly Earnings Seasons, Joe López Vilaró
Index Fund Ownership And Stock Price Efficiency: Evidence From Quarterly Earnings Seasons, Joe López Vilaró
Graduate Theses and Dissertations
While prior research argues that individual investors benefit from a switch to passive investment in index funds (French 2008, Bond and García 2022), higher levels of index fund ownership of firm shares lead to competing factors that influence a firm’s price efficiency (i.e., the speed and accuracy with which a firm’s stock price reflects investor consensus on the information provided about a firm). If relative investor sophistication increases as index fund ownership increases, there is a benefit to the firm’s price efficiency. Yet, more shares held passively limit the shares available for investors to actively incorporate firm news, adversely impacting …
Abolition’S Informal Gatekeepers: The Role Of County Courts In The Making Of Pennsylvania’S ‘Free’ Border, Amanda Mcgee
Abolition’S Informal Gatekeepers: The Role Of County Courts In The Making Of Pennsylvania’S ‘Free’ Border, Amanda Mcgee
Graduate Theses and Dissertations
Because Pennsylvania was the first state to implement legislation that slowly ended slavery within the state, contests over freedom and the enforcement of where it began and ended became an essential element of Pennsylvania’s border-making policies in the late eighteenth and early nineteenth century. The struggle over the territorial extent (by which I mean legal and geographical) of Pennsylvania abolition between enslavers intent on retaining their human chattel by any means necessary and enslaved men and women intent on asserting their freedom once they touched Pennsylvania “free soil” in turn, served to solidify the geopolitical boundary of the state in …
Enhancing Depression Screening And Treatment For Latinxs Residing In The U.S., Linda Esperanza Guzman
Enhancing Depression Screening And Treatment For Latinxs Residing In The U.S., Linda Esperanza Guzman
Graduate Theses and Dissertations
Introduction: In the U.S., Latinxs with Spanish as their preferred language encounter two prominent structural barriers impacting access to treatment for major depressive disorder (MDD). The first is that MDD symptoms commonly go undetected in Latinxs with Spanish compared to English as their preferred language. This might be perhaps because commonly used MDD screeners lack somatic symptom survey items culturally specific in how MDD may present among Latinxs with Spanish as their preferred language. The second structural barrier is that treatment access and completion rates are lower in Spanish-speaking than English-speaking Latinxs, perhaps due to treatments lacking the structure and …
Rice Material State Diagrams: Trends Of Contemporary Cultivars And Influence Of Nitrogen Application During Production, Evans Ameyaw Owusu
Rice Material State Diagrams: Trends Of Contemporary Cultivars And Influence Of Nitrogen Application During Production, Evans Ameyaw Owusu
Graduate Theses and Dissertations
Rice is typically harvested at high moisture content (MC) levels which necessitates drying to low MC levels for safe storage. However, drying at inappropriate temperatures and durations can lead to deterioration of kernel quality such as fissure formation. Kernels with these fissures are typically associated with reduced head rice yields and significant economic losses. Material state diagrams for rice have been created by the University of Arkansas Rice Processing Program (UARPP) as a tool to aid in predicting the ideal temperatures to use during drying and tempering (a process of holding rice at the drying temperature for some duration). The …
