Improving Establishment Of Seeded Buffalograss, Luqi Li

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Buffalograss [Buchloë dactyloides (Nutt.) Engelm.] is a warm-season grass native to the North American Great Plains. Buffalograss is drought resistant, heat resistant and cold tolerant, and thus is well-adapted to many uses in areas that require low maintenance or erosion control. Since buffalograss is slow-growing, one challenge of establishing seeded buffalograss is to maximize seedling maturation and establishment before winter. We evaluated dormant seeding buffalograss in late fall and winter, when germination is not expected until soils warm in spring. We successfully dormant seeded ‘Sundancer’, ‘Bowie’ or ‘Cody’ buffalograss at 146 kg ha^-1 from late November though …

Animal Cities: Post-Human Urban Wildness, Jing Huang

Architecture Thesis Prep

This thesis contends that architecture should be designed in a way to foster closer human-animal relationships. Cities are typically designed solely with the human in mind, and over time, animals have been pushed out of the city, decreasing biodiversity. Peoples’ tendency is to separate themselves and domesticate animals, resulting in sterile and tame urban centers. This is a result of the different attitudes humans have cultivated towards animals; dirty/clean, pleasant/annoying, useful/useless, harmless/dangerous, awe/disgust, etc., and utilizing architecture as means of filtering the presence of those that are beneficial to us, rendering animals as an afterthought. In a way, humans have …

Modeling Trade-Offs Between Plant Fiber And Toxins: A Framework For Quantifying Risks Perceived By Foraging Herbivores, Meghan J. Camp, Lisa A. Shipley, Timothy R. Johnson, Jennifer Sorenson Forbey, Janet L. Rachlow, Miranda M. Crowell

Biology Faculty Publications and Presentations

When selecting habitats, herbivores must weigh multiple risks, such as predation, starvation, toxicity, and thermal stress, forcing them to make fitness trade-offs. Here, we applied the method of paired comparisons (PC) to investigate how herbivores make trade-offs between habitat features that influence selection of food patches. The method of PC measures utility and the inverse of utility, relative risk, and makes trade-offs and indifferences explicit by forcing animals to make choices between two patches with different types of risks. Using a series of paired-choice experiments to titrate the equivalence curve and find the marginal rate of substitution for one risk …

Fire And Flood Expand The Floodplain Shifting Habitat Mosaic Concept, W. J. Kleindl, Mark C. Rains, L. A. Marshall, F. R. Hauer

School of Geosciences Faculty and Staff Publications

The floodplain shifting habitat mosaic concept suggests that habitat patch dynamics are influenced by hydrologic disturbances driven by flood pulses of sufficient power to initiate incipient motion of the substratum and maintain cut-and-fill alluviation of the channel and banks. However, floodplain habitat mosaics are subject to other important landscape-scale disturbance regimes. In the Rocky Mountains of the USA and Canada, fire also affects floodplain habitat patch composition. The floodplain exists at the intersection of disturbance regimes that shape the riverscape and those that shape the landscape. We extended the shifting habitat mosaic concept by examining the effects of multiple disturbance …

Midfield Rf Signal Detector, Dawei Zhang

Electrical Engineering

This project is part of a Master’s thesis which looks at alternative ways to measure blood glucose. The Master’s thesis uses mid-field signals in order to match impedance and therefore lose less power as they travel through flesh. The goal of this senior project is to build a receiver for those signals and give accurate RSSI (received signal strength indicator) measurements. Mid-fields were originally explored by Stanford professor Dr. Ada Poon [3] who used the signaling technique to recharge the batteries of deeply implanted devices. Devices implanted near the surface of the skin were able to have their batteries recharged …

Effects Of Gender And School Size On Mathematics And Science Achievement For Students In Western Arkansas, Jason Edward Moore

College of Education Dissertations

The purpose of this dissertation was to research the effects of gender and school size on mathematics and science achievement for schools in western Arkansas. Related research revealed historical performance gaps in mathematics and science achievement between males and females, but also showed that those gaps have closed over the past few decades. However, the research also showed that there is still a large gap in the number of males and females working in Science, Technology, Engineering, and Mathematics (STEM) careers. This study also investigated this trend within western Arkansas to determine whether the gender gap in STEM is caused …

The Providence Alaska Cancer Center staff randomly selected the records of 200 cancer patients between 2010 and 2011, using the cancer tumor registry. Data were analyzed to answer four specific questions that addressed the 1) presence of a Primary Care Physician (PCP), 2) number and type of …

Taxing Working Memory: The Effects On Category Learning, Ashley Ercolino

HIM 1990-2015

In the past decade, the COVIS model (Ashby, Alfonso-Reese, Turken, & Waldron, 1998) has emerged as the only neuropsychological theory for the existence of multiple brain systems for category learning. COVIS postulates that there are two systems, explicit and implicit, which compete against one another. These two systems reply on two discrete networks: explicit, or rule based categorization relies on executive function and working memory while implicit, or information integration categorization is mediated by dopaminergic pathways. The purpose of this pilot study was to further provide evidence for the existence of multiple systems of category learning. In all three experiments, …

An Examination Of The Factors That Impact Elementary School Principal's Perceptions Of Their Leadership Role, Kathryn M. Kish

HIM 1990-2015

A growing body of research supports the idea that large-scale school reform efforts often fail to create sustained change within the public school sector. When implementing deep organizational change, both novice and veteran educators are challenged to learn new skills, reexamine their instructional practice and content knowledge, and re-shape their underlying beliefs and values about schools. This qualitative study explored principals’ perceptions of their leadership roles in the school system. Data collection was done through a series of three interviews with three elementary school principals in Central Florida. In addition to their perceptions, it also studied factors that may influence …

Family Struggles And Substance Use Among First Generation College Students, Barbara Vehabovic

HIM 1990-2015

The current study seeks to examine the relationship between family struggles, as measured by social class and parental marital status, and substance use among first-generation college students. 902 students from the University of Central Florida participated in an online questionnaire that assessed their social class, parents’ marital status, drug and alcohol use, as well as demographic variables. Results indicated a significant positive correlation between substance use and social class as well as generational status. Males were also more likely to use drugs and alcohol than females. A regression analysis indicated social class, gender, junior and senior academic years were all …

Role Of B Cell Receptor Signaling In Il-10 Production By Normal And Malignant B-1 Cells., Sara S Alhakeem, Vishal J Sindhava, Mary K Mckenna, Beth W Gachuki, John C Byrd, Natarajan Muthusamy, Subbarao Bondada

Microbiology, Immunology, and Molecular Genetics Faculty Publications

B-1 cells are considered innate immune cells, which produce the majority of natural antibodies. B-1 cell responses to B cell receptor (BCR) and Toll-like receptor ligation are tightly regulated owing to the cross-reactivity to self-antigens. CD5 has been shown to play a major role in downregulation of BCR responses in B-1 cells. Here, we provide evidence for another mechanism by which BCR response is regulated in B-1 cells. B-1 cells, as well as their malignant counterpart, B cell chronic lymphocytic leukemia (B-CLL) cells, produce interleukin-10 (IL-10) constitutively. IL-10 secretion by normal B-1 cells downregulates their proliferation responses to BCR ligation. …

An Epigenetic Toolkit Allows For Diverse Genome Architectures In Eukaryotes, Xyrus X. Maurer-Alcalá, Laura A. Katz

Biological Sciences: Faculty Publications

Genome architecture varies considerably among eukaryotes in terms of both size and structure (e.g. distribution of sequences within the genome, elimination of DNA during formation of somatic nuclei). The diversity in eukaryotic genome architectures and the dynamic processes are only possible due to the well-developed epigenetic toolkit, which probably existed in the Last Eukaryotic Common Ancestor (LECA). This toolkit may have arisen as a means of navigating the genomic conflict that arose from the expansion of transposable elements within the ancestral eukaryotic genome. This toolkit has been coopted to support the dynamic nature of genomes in lineages across the eukaryotic …

Study Of Homogeneous Mineral Acid Dehydration Of Monosaccharides In A Cstr, Siddharth Sharad Bhat

Dissertations - ALL

Simple sugars (Aldohexoses/pentoses), (Ketohexoses/pentose) when subjected to a dehydration reaction, produce various compounds. An example of one such compound is 5-hydroxymethyl furfural. Such chemical products may be used in subsequent processing steps (hydrolysis, aldol condensation, hydrogenation and dehydration) to produce similarly structured condensed compounds that form the basis of complex molecules used in various industries such as production of fuels, chemical reagents and fertilizers. Most studies focus on heterogeneous packed beds and batch reactors to carry out dehydration reactions. This study illustrates use of a Continuous Stirred-Tank reactor to carry out such dehydration reactions. In order to maintain the homogenous …

Deciphering The Neuroprotective Potential Of Interleukin-1Β (Il-1Β) Using In Vitro Murine Models Of Oxidative Stress, Twinkle Chowdhury

Dissertations - ALL

Interleukin-1β (IL-1β), a key cytokine driving neuroinflammation in the Central Nervous System (CNS), is enhanced in many neurological diseases/disorders, including but not limited to ischemic stroke, Parkinson's disease, Amyotrophic Lateral Sclerosis, Huntington's disease and Alzheimer's disease. The dominant view is that IL-1β contributes to and/or sustains pathophysiological processes. However, other studies demonstrate that IL-1β can play an important role in neural protection and repair. It may do so by modifying astrocyte behavior. Indeed, studies from our laboratory demonstrate that IL-1β increases the synthesis and release of the antioxidant molecule glutathione (GSH) from astrocytes and that IL-1β-treated astrocytes show increased resistance …

This transformation was accomplished via a recently developed tandem silylative coupling using RuHCl(CO)(PCy3)2. The reaction optimization, mechanistic hypothesis and substrate scope for the coupling with acrylates and vinyl boronates is described. The vinyl boronate scope and alkyne scope is presented, in addition to the selective derivatization of the …

Optimizing Acyclic Identification Of Aptamers, Caitlin M. Miller

Dissertations - ALL

The minimal human alpha-thrombin binding aptamer, d(GGTTGGTGTGGTTGG), has previously been successfully identified from a DNA library of randomized hairpin loop, m=15, with the High Throughput Screening of Aptamers (HTSA) technique, later termed Acyclic Identification of Aptamers (AIA). AIA eliminated the need for multiple cycles of in vitro evolution typically used for aptamer discovery by employing libraries with an over-representation of all possible sequences and high throughput sequencing. Although the method was successful at identifying the thrombin binding aptamer, improvements to partitioning and sample preparation inconsistencies encountered during replication attempts were necessary in order to maximize its value. Subsequent revisions and …

Effects Of Dissonance And Disruption On Risky Decisions, Wyn E. Taylor

Psychology Theses - Archive

All choices develop first from the basic sensory stimuli to which our systems attend, consciously and unconsciously. The cognitive processes which form the basis of decision- making and contextual shifting require attention to both novel and familiar environmental features; from the overwhelming stimulus that assault our senses, we must figure out which environmental features are safe to ignore and those to which we must attend. Separate fast, emotional and slower rational decision processes described by a number of dual-processing theories have found compelling support in neuroscience research examining selective attention gating mechanisms. Indeed, these two systems appear to exert substantial …

From Attention Deficit Hyperactivity Disorder To Substance Use Disorder: Perspectives From Recovering Addicts, Elena Potovsky

Dissertations, Masters Theses, Capstones, and Culminating Projects

People who have Attention Deficit Hyperactivity Disorder (ADHD) are often at high risk of acquiring Substance Use Disorder (SUD). When a diagnosis is determined for a school age child, the special education team mainly focuses on the most obvious problems that occur with ADHD: executive function issues, reading and writing impairments, and disruptive behavior. They may not realize how common it is for those identified with ADHD to also acquire SUD.

The literature revealed that there may be a shared genetic basis between ADHD and SUD, that there is commonly an early onset of SUD for those who have ADHD, …
