Distribution And Characterization Of The Soybean Cyst Nematode, Heterodera Glycines (Hg) Types In South Dakota, Krishna Acharya
Electronic Theses and Dissertations
The soybean cyst nematode (SCN), Heterodera glycines Ichinohe, is an endoparasitic nematode and one of the major pests of soybean (Glycine max L.) in the United State and all over the world where soybean is grown. SCN is ranked first among the biological factors that cause yield loss in soybean. The estimated yield loss by this nematode is $1b annually in the United States alone. SCN is thought to have been first found in China. It was first identified in the United States in 1954 in North Carolina and in South Dakota in 1995. To date, SCN continues to spread …
Ice Concentration Linked With Extractive Stirrer (Icecles), Nujud Omar Maslamani
Ice Concentration Linked With Extractive Stirrer (Icecles), Nujud Omar Maslamani
Electronic Theses and Dissertations
Clean water is very important for human health. Therefore, drinking water contamination is a significant research concern, especially with the increasing global population. Some contaminants, such as pesticides, can cause health effects even at low levels. Therefore, trace and ultratrace analysis of contaminants in drinking water is essential. Ultratrace analysis typically requires highly effective sample preparation methods and/or highly sensitive instruments. There are currently advanced sample preparations techniques available to analytical chemists that may allow trace analysis of certain analytes. These include liquid-liquid extraction (LLE), solid phase extraction (SPE), solid phase micro extraction (SPME), and stir bar sorpitive extraction (SBSE). …

Effects Of Visitors And Enrichments On Behavior Of Captive Red Wolves’ (Canis Rufus) At The Great Plains Zoo, Sioux Falls, South Dakota, Kylee S. Shotkoski
Electronic Theses and Dissertations
Red wolves (Canis rufus) are the first animals to maintain a wild population from captive, released individuals. A captive breeding program for red wolves was started before complete extirpation, and 4 breeding pairs were released in Alligator River National Wildlife Refuge (North Carolina) in 1987 and a small wild population still exists there. Currently, there are several captive breeding facilities for red wolves within the Species Survival Plan (SSP) program. The Great Plains Zoo in Sioux Falls, South Dakota participates in the SSP program. My study was initiated to create a natural history background and evaluate interaction between …
A Physiological Assessment Of Wetland Habitats For Spring-Migrating Ducks In The Agricultural Landscapes Of The Southern Prairie Pothole Region, Adam K. Janke
Electronic Theses and Dissertations
The conversion of grassland and wetland ecosystems in the Prairie Pothole Region (PPR) has been a pervasive challenge for conservationists dating back to the early 1900s. The legacy of ever-increasing agricultural intensity in the southern portions of the PPR, including eastern South Dakota, has left many wetland ecosystems in a matrix of intensive agricultural production. With little surrounding nesting cover, these wetlands are thought to have limited potential for waterfowl reproduction but may still play an important role facilitating migration of waterfowl en route to northern breeding areas during spring. My research sought to understand the contributions of wetlands in …

Understanding The Impact Of Non-Thermal Processing And Co2 Assisted Extrusion On Antioxidant, Textural And Functional Properties Of Corn, Sorghum And Apple Pomace Based Extrudates, Umesh Chandra Lohani
Electronic Theses and Dissertations
Currently, there is a worldwide demand for antioxidant rich foods in diet, especially ready to eat foods, i.e. cereals and snacks. In recent years, the research has got momentum to valorize the underutilized crops, i.e. millet, sorghum and industrial food by-products, i.e. fruit pomace to incorporate into main stream of human diet due to their enrichment in nutritional as well as bioactive compounds like phenolic and flavonoid antioxidants. However, most of the phenolic compounds in plant are present in the bound form with the carbohydrates, lignin, pectin and proteins which reduces their ability to function as good antioxidants. Therefore, in …
An Examination Of The Lived Curiosity Experiences Of Traditionally-Aged Freshmen Pursuing And Education Degree, Susan Kelly
An Examination Of The Lived Curiosity Experiences Of Traditionally-Aged Freshmen Pursuing And Education Degree, Susan Kelly
Electronic Theses and Dissertations
The benefits of being curious continue beyond infancy and early childhood. Curiosity has been linked to academic achievement, memory, and lifelong learning. Yet curiosity type behaviors in academic settings are infrequently observed. This is a concern because some of the students graduating from the educational system will be the teachers responsible for fostering conditions that spark curiosity and exploration for future students. These prospective teachers' lived curiosity experiences will influence their future teaching beliefs and practices. Yet few studies have been conducted that illuminate the lived curiosity experiences of prospective teachers. The research question that guided this study was, what …

The Lived Experiences Of Elementary Students With Disabilities Self-Advocating Through Speaking And Writing, Lindsey Massengale
The Lived Experiences Of Elementary Students With Disabilities Self-Advocating Through Speaking And Writing, Lindsey Massengale
Electronic Theses and Dissertations
Writing and self-advocacy skills are important for all students, including individuals with disabilities. Within the K-12 setting, those skills are taught, but emphasis changes as students progress through the grade levels. At the elementary level, writing is more prominent; whereas, in high school, self-advocacy becomes a focus. In this study, the researcher used a phenomenological research design to explore the lived experiences and preferences of elementary students with disabilities and their use of self-advocacy strategies in the inclusive setting, both in writing and speaking. The phenomenon was explored over an eleven-week period in a second grade, inclusive classroom. The conceptual …

Setting The Agenda For Stem Literacy In Higher Education: A Content Analysis Of The Chronicle Of Higher Education, Maya Abdallah
Electronic Theses and Dissertations
Enhancing achievement in Science, Technology, Engineering, and Mathematics (STEM) is a long-standing national concern. The current national agenda, to instill an "all hands on deck" approach to creating a STEM literate citizenry, calls for broadening the scope of inclusion in STEM efforts. A critical population, higher education administrators, faculty, and staff are a valuable resource to advancing this agenda. Under the proposed Agenda Setting Communication Theory (ASCT) model developed for this study, their level of exposure to needed information is an important indicator of their potential participation in this agenda. As the leading news medium for the higher education community, …
Bullying Victimization, Feared Second Language Self, And Second Language Identity: Reconceptualizing The Second Language Motivational Self System, Hilal Peker
Electronic Theses and Dissertations
Factors affecting English learners' (ELs) motivation and identity have been explored in second language (L2) learning contexts; however, research examining L2 motivation and identity under the effect of bullying victimization is rare although ELs are one of the populations that are physically and psychologically affected from bullying. Using a unique perspective by merging L2 motivation, L2 identity, and bullying concepts under social ecological framework, this dissertation study is the first study investigating the relationship between bullying victimization, L2 Motivational Self System, and L2 identity. The data were derived from 1022 ELs through a self-report survey that was adapted and tested …
Evaluation Of The Expectancy Challenge Alcohol Literacy Curriculum (Ecalc) For High School Students, Alyssa Dietz
Evaluation Of The Expectancy Challenge Alcohol Literacy Curriculum (Ecalc) For High School Students, Alyssa Dietz
Electronic Theses and Dissertations
Prevention efforts targeted at children and adolescents are important because alcohol consumption contributes to the three leading causes of death in this among 12-20 year-olds: unintentional injury, homicide, and suicide. Research on the causes of alcohol misuse traditionally focused on pharmacological and genetic explanations, but models have expanded to include cognitive processes in the development of alcohol use patterns. Alcohol expectancies, or beliefs about the effects of alcohol, are an important influence on drinking behavior. Expectancies exist prior to the initial drinking experience, predict the onset of alcohol consumption, differentiate both children and adults in terms of light- and heavy-drinking …
Superwholock: An Analysis Of Subculture In A Microblogging Setting, Dean Short
Superwholock: An Analysis Of Subculture In A Microblogging Setting, Dean Short
Electronic Theses and Dissertations
While subcultural research has always been a common focus of sociological research, most such studies focus on deviant subcultures. This has led to a glut of information on countercultures and criminal subcultures, but relatively little study of less visible subcultures. While there is a great deal of research on the sociology of sport, including sport fandom, there is very little on other fandom subcultures. While this makes sense, as they are niche subcultures, the popularity of formerly niche entertainment is expanding rapidly. Much of this fandom renaissance owes its existence to the Internet, and its ability to bring geographically separate …
Don't Let The World Rot: Anarchism, Hardcore Music, And Counterculture, Pearson Bolt
Don't Let The World Rot: Anarchism, Hardcore Music, And Counterculture, Pearson Bolt
Electronic Theses and Dissertations
Hardcore music is intrinsically anarchistic. The hardcore music scene represents a radical departure from contemporary society. Rejecting the materialism, militarism, and hedonism of the mainstream music scene—and, by extension, modern culture—hardcore music presents an alternative lifestyle rooted in solidarity, equality, and liberty. Indeed, the culture of the hardcore scene approaches a transitive, nomadic model of an anarchistic commune built on resistance as a way of life. In this study, I identified the ways music and lyrics craft attitudes and environments for revolt and rebellion, cultivating critical thinking and disobedience in equal measures. In order to understand the hardcore community, I …
Pasture Management, The Red Imported Fire Ant (Solenopsis Invicta) And Dung Beetle Mediated Ecosystem Services, Christen Steele
Pasture Management, The Red Imported Fire Ant (Solenopsis Invicta) And Dung Beetle Mediated Ecosystem Services, Christen Steele
Electronic Theses and Dissertations
Grazing animals in Florida deposit over 20 million metric tons of dung per year, making dung a significant non-point source of pollution (extrapolated from Fincher, 1981). Degradation of this dung occurs naturally, primarily due to a diverse group of beetles (Order Coleoptera) primarily in the families Scarabaeidae and Geotrupidae(hereafter dung beetles). Dung that is not degraded becomes a non-point source of pollutants and may be leached into water bodies. Additionally, dung provides an incubation site for the pests and parasites of both humans and livestock. Thus, as dung beetles consume and degrade dung, they provide a multitude of ecosystem services …

Vulture Scavenging Of Child-Sized Pig Carcasses In Central Florida: Utilizing Gis To Analyze Site Variables Affecting Skeletal Dispersal, Alexander Mitchell
Electronic Theses and Dissertations
Scavengers can significantly alter a forensic scene and consume, modify, disarticulate, and disperse bodies. However, little research exists regarding scavenging in Central Florida, specifically scavenging involving Black and Turkey Vultures (Coragyps atratus, Cathartes aura respectively). The purpose of this study is to examine the effects of vulture scavenging on consumption, disarticulation, and dispersal of child-sized carcasses in the Central Florida region. The research sample consisted of four pig (Sus scrofa) carcasses weighing approximately 25kgs that were deposited in two distinct sites (shaded and unshaded) at the Deep Foundations Geotechnical Research Site located on the UCF campus. Two field cameras were …
Role Of Sleep In Exposure Therapy For Posttraumatic Stress Disorder In Oif/Oef Combat Veterans, Franklin Mesa
Role Of Sleep In Exposure Therapy For Posttraumatic Stress Disorder In Oif/Oef Combat Veterans, Franklin Mesa
Electronic Theses and Dissertations
Exposure therapy is theorized to reduce posttraumatic stress disorder (PTSD) symptomatology by promoting habituation/extinction of fear responses to trauma-related cues. Empirical evidence indicates that emotional memory, including habituation/extinction learning, is enhanced by sleep. However, service members with combat-related PTSD often report disturbed sleep. In this study, quality of sleep and indicators of extinction learning were examined in veterans of recent wars who had completed an exposure-based PTSD intervention. Fifty-five participants were categorized into two groups based on self-reported quality of sleep: low sleep disruption severity (LSDS; N = 29) and high sleep disruption severity (HSDS; N = 26). Participants in …

Bmp-7 Inhibits P38 And Jnk Pathways And Increases M2 Macrophage Differentiation To Reduce Atherosclerosis In Apolipoprotein E-/- Mice, Heidi Shoulders
Electronic Theses and Dissertations
We have previously shown that treating atherosclerosis with bone morphogenetic protein-7 (BMP-7) affects the presence of macrophage subtypes in vitro, however it remains unknown whether BMP-7 treatment affects development and progression of atherosclerosis in vivo at an early and mid-stage of the disease. We therefore performed a Day 5 (D5) and Day 28 (D28) study to examine BMP-7's potential to affect monocyte differentiation. Atherosclerotic plaque formation was developed using our standard method and ApoE-/- mice were sacrificed at D5 and D28 post-surgery. Treatment animals received intravenous injections of BMP-7 at 200µg/kg of bodyweight. Hematoxylin and Eosin morphological stain shows that …

Nightgaze: A Microbudget Visual Mixtape, Maillim Santiago
Electronic Theses and Dissertations
Nightgaze is a feature length visual mixtape created by May Santiago to fulfill the Masters of Fine Arts program at UCF. The mixtape is a study of autobigraphical depression in metaphorical visual tracks. Originally conceived as an experimental narrative, it has evolved into a form of essayistic distance within a narrative framework with experimental deviations. This thesis tracks the project from its original conception, through the pre-production, production, and post-production processes. It also formulates a plan for marketing and distributing the project.
Improved Interpolation In Sph In Cases Of Less Smooth Flow, Oddny Brun
Improved Interpolation In Sph In Cases Of Less Smooth Flow, Oddny Brun
Electronic Theses and Dissertations
We introduced a method presented in Information Field Theory (IFT) [Abramovich et al., 2007] to improve interpolation in Smoothed Particle Hydrodynamics (SPH) in cases of less smooth flow. The method makes use of wavelet theory combined with B-splines for interpolation. The idea is to identify any jumps a function may have and then reconstruct the smoother segments between the jumps. The results of our work demonstrated superior capability when compared to a particular challenging SPH application, to better conserve jumps and more accurately interpolate the smoother segments of the function. The results of our work also demonstrated increased computational efficiency …

The research evaluates violations, which occurred while arrestees were assigned to GPS in 2009 and 2013; the programs first year and the most recent with complete data available. The results found limited factors that could be identified as predicting violations for those who violated the GPS, but the qualitative interviews shed much more light on the value of the program. The qualitative interviews were conducted with various …
From Pet To Pest? The Potential Global Range And Food Web Effects Of A Generalist Carnivore, Hannah Bevan
From Pet To Pest? The Potential Global Range And Food Web Effects Of A Generalist Carnivore, Hannah Bevan
Electronic Theses and Dissertations
The Nile monitor lizard [Varanus niloticus (Linnaeus, 1766)] is a generalist carnivore, native to Sub-Saharan Africa and the Nile River but now established in North America as a result of the pet trade. Once introduced, they are a potential invasive threat to native wildlife. Here, I create ensemble species distribution models (SDMs) to predict the global distribution of this generalist carnivore given current and future climate conditions. I then quantify the monitor's potential effects on 85 food webs representing >900 different species within the projected regions based on stomach content data. Climate, vegetation, and elevation data are used for 507 …

To achieve this, the thesis summarized current scholarship on Soviet and Red Army policies toward Muslims. The thesis analyzed the oral histories and written accounts of Muslim soldiers and Russian soldiers to understand the perceptions of Russians and Muslim soldiers. A hierarchy of cultural backwardness underlined Soviet policies in …
The Russian Connection: How Russia Became A Leader In The World's Human Trafficking Market, Anthony De Mauro
The Russian Connection: How Russia Became A Leader In The World's Human Trafficking Market, Anthony De Mauro
Electronic Theses and Dissertations
This thesis assesses how the history of the USSR and its collapse affected the human trafficking market. By conducting a historical analysis of the Soviet Union, key aspects of Soviet society were determined that allowed for the human trafficking market to establish and operate extremely lucratively; a focus on some of the established factors of human trafficking including corruption, law enforcement, the economy, organized crime, and the dissolution of the Soviet government. While this thesis highlights the historical factors of Russian human trafficking, this thesis does not determine why human trafficking exists beyond the surface exploitation that human trafficking consists …
The Longitudinal Relationship Between Moderate Alcohol Use And Cognitive Aging Among Older Adults., Danielle Herring
The Longitudinal Relationship Between Moderate Alcohol Use And Cognitive Aging Among Older Adults., Danielle Herring
Electronic Theses and Dissertations
Cognitive aging appears inconsistent across cognitive domains, indicating that domains may not all decline at the same rate across individuals. Individual trajectories of cognitive aging can vary widely and are affected by numerous lifestyle and health factors. Alcohol use among older adults is known to confer both health risks, typically related to excessive use, and protective effects, often associated with moderate consumption. Moderate alcohol use has been linked with better cognitive functioning as well as a decrease in cardiovascular mortality and systemic inflammation, as compared to heavy or abstinent users. Given that extant research has identified C-reactive protein (CRP) as …
Neurological Profile Of Older Apoe-Pon1 Double Knockout Mice, Connie Mitra
Neurological Profile Of Older Apoe-Pon1 Double Knockout Mice, Connie Mitra
Electronic Theses and Dissertations
Atherosclerosis is a cardiovascular disease where plaques made up of lipids in the form of cholesterol ester build up in the carotid and innominate arteries that supply blood to the brain. Accumulation of the plaques limit the flow of blood and nutrients to the brain, leading to diminished oxygen supply, increased oxidative stress and cell death. All these have been implicated in Alzheimer's disease (AD). Alzheimer's disease, a chronic, progressive, age related neurodegenerative disorder is the most common form of dementia in the elderly accounting for 60-80% of the cases. Clinically, Alzheimer's disease is characterized by loss of memory, damage …
Diet And Migration In Coastal Oaxaca: Identifying Effects Of Political And Social Collapse Through The Utilization Of Stable Isotope Analysis, Jacklyn Rumberger
Diet And Migration In Coastal Oaxaca: Identifying Effects Of Political And Social Collapse Through The Utilization Of Stable Isotope Analysis, Jacklyn Rumberger
Electronic Theses and Dissertations
This study involves the investigation of diet and mobility among people living in the lower Río Verde Valley, Oaxaca, Mexico, during the Late Classic (AD 500-800) and Early Postclassic (AD 800-1200) periods. Specifically, this research focuses on how political and social collapse affected subsistence practices and diet, particularly maize agriculture and consumption, as well as human migration. Archaeological evidence suggests that Río Viejo, the region's largest urban center before AD 800, experienced multiple periods of political fragmentation and instability during its long history, specifically during the Early Classic (AD 250 - 500) and Early Postclassic periods, making it an ideal …
Role Of Kruppel-Like Factor 8 (Klf8) In Cancer And Cardiomyopathy, Satadru Lahiri
Role Of Kruppel-Like Factor 8 (Klf8) In Cancer And Cardiomyopathy, Satadru Lahiri
Electronic Theses and Dissertations
Cancer and cardiovascular diseases are two most fatal diseases causing innumerable death each year. Understanding the mechanisms underlying these diseases is critical for developing proper therapeutic approach. Kruppel-like factor 8 (KLF8) is a member of Kruppel-like family transcription factors that is overexpressed in many types of cancers. There is no report on role of KLF8 in cardiovascular diseases to date. KLF8 transcriptionally activates or represses a host of target genes to promote cancer cell proliferation, migration, invasion and epithelial to mesenchymal transition during tumor progression. Studies proposed in this thesis identified a novel posttranslational modification of KLF8 essential for its …
Multidimensional Room-Temperature Fluorescence Microscopy For The Nondestructive Analysis Of Forensic Trace Textile Fibers, Nirvani Mujumdar
Multidimensional Room-Temperature Fluorescence Microscopy For The Nondestructive Analysis Of Forensic Trace Textile Fibers, Nirvani Mujumdar
Electronic Theses and Dissertations
The purpose of this dissertation is to advance nondestructive methodology for forensic fiber examination. Non-destructive techniques that can either discriminate between similar fibers or match a known to a questioned fiber – and still preserve the physical integrity of the fibers for further court examination - are highly valuable in forensic science. A challenging aspect of forensic fiber examinations involves the comparison of fibers colored with visually indistinguishable dyestuffs. This is not an uncommon situation, as there are numerous indistinguishable fibers pre-dyed with commercial dyes of virtually identical colors. Minimal chemical structural variations are actually encouraged by the dye patent …
Individual Differences In Trust Toward Robotic Assistants, Tracy Sanders
Individual Differences In Trust Toward Robotic Assistants, Tracy Sanders
Electronic Theses and Dissertations
This work on trust in human-robot interaction describes a series of three experiments from which a series of predictive models are developed. Previous work in trust and robotics has examined HRI components related to robots extensively, but there has been little research to quantify the influence of individual differences in trust on HRI. The present work seeks to fill that void by measuring individual differences across a variety of conditions, including differences in robot characteristics and environments. The models produced indicate that the main individual factors predicting trust in robotics include pre-existing attitudes towards robots, interpersonal trust, and personality traits.
