Microfinance In Latin America: Poverty Alleviation And The Impact Of Institutional Mimicry, Lindsay Jouben

Graduate Theses, Dissertations, and Problem Reports (ETD)

Microfinance has become a program of choice in the international development community. The World Bank has promoted microfinance programs under the idea that poverty alleviation can be accomplished by mainly providing credit. [1] As such, these policies are often replicated throughout the developing world. This replication is done through international organizations adopting a standard of best practices for the microfinance field. Best practices consist of a complex set of standard by which all banks must adhere if they receive funding from the World Bank or International Monetary Fund. These best practices, following neoliberal economics, lay out how microfinance should operate …

A Spatially Distributed Investigation Of Stream Water Temperature In A Contemporary Mixed-Land-Use Watershed, Jason P. Horne

Graduate Theses, Dissertations, and Problem Reports (ETD)

Stream water temperature is an important physical variable that influences many biological and abiotic water quality processes. The land-use/land-cover (LULC) types and corresponding variability in stream water temperature (Tw) processes in contemporary mixed-land-use watersheds necessitate research to advance management and policy decisions. Water temperature was analyzed from 21 gauging sites using a nested-scale experimental watershed study design. Results showed that forested land use was significantly negatively correlated (α = 0.05) with mean and maximum Tw. Agricultural land use was significantly positively correlated (α = 0.05) with maximum Tw except during the spring season. Mixed development and Tw were significantly correlated …

Structural Transformations Of Synaptic Partners During Growth And Competition Of The Giant Nerve Terminal, The Calyx Of Held, In The Medial Nucleus Of The Trapezoid Body In The Developing Postnatal Mouse, Dakota Richard Jackson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Across many parts of the nervous system, initial neural circuit assembly involves stereotyped stages of early axonal proliferation within target territories, selective reinforcement of a subset of inputs and the removal of exuberant or unneeded connections via either activity or experience-dependent mechanisms, in a process referred to as synaptic competition. The mechanisms and associated structural transformations that underlie and define these stages of neurodevelopment have been examined in a variety of brain regions including the peripheral neuromuscular junction, the central climbing fiber innervation of cerebellar Purkinje cells and retinal ganglion cell innervation of the thalamic lateral geniculate nucleus. Each of …

Improving The Biological Control Of Persicaria Perfoliata (Polygonaceae) Using Rhinoncomimus Latipes Korotyaev (Coleoptera: Curculionidae), Jaewon Kim

Graduate Theses, Dissertations, and Problem Reports (ETD)

Persicaria perfoliata (L.) H. Gross (Polygonaceae; Mile-a-minute weed) is a rapid-growing invasive vine introduced from eastern Asia to northeastern United States in the 1930s. This vine has been invaded in disturbed areas and reforestation sites in 15 states in the U.S. and forms dense, monocultural patches that may inhibit natural forest regeneration. To control this weed, a host-specific biocontrol agent, Rhinoncomimus latipes Korotyaev (Coleoptera: Curculionidae) has been released in the P. perfoliata invaded states in the U.S. during the past 15 years. Currently, R. latipes is released by hand to the invaded area where the presence of the weed is …

Genetic And Biochemical Characterization Of Ergot Alkaloid Synthesizing Fungi And Their Symbionts, Matthew Duane Maust

Graduate Theses, Dissertations, and Problem Reports (ETD)

Ergot alkaloids are fungal tryptophan derived toxins which affect mammalian circulation and neurotransmission. These compounds are biosynthesized by a conserved genetic pathway, known as the ergot alkaloid synthesis (EAS) pathway by fungi belonging to the ascomycete families Trichocomaceae and Clavicipitaceae. Several Ipomoea species and related plants in the morning glory family harbor vertically transmitted symbiotic fungi in the genus Periglandula, also members of Clavicipitaceae, that produce ergot alkaloids. Metabolomic analysis of seeds identified a previously uncharacterized glycoside form of the pharmaceutically important ergot alkaloid, ergonovine. Several species belonging to the fungal genus Metarhizium have recently been shown to have the …

The Effects Of Internal Physiology On Polyphenic Horn Development In The Dung Beetle Onthophagus Taurus, Naomi Garrett Williamson

Graduate Theses, Dissertations, and Problem Reports (ETD)

An organism’s phenotype can be affected in development by alterations to gene expression based on environmental inputs. Nutrition is one such environmental input and the central regulator of development of large horn or small horn phenotypes in the dung beetle species, Onthophagus taurus. However, little is known about the nature of chemical compounds that are critical to this plastic horn development. To better understand these compounds, we are utilizing an untargeted metabolomic approach as well as a targeted gene approach. Through the metabolomic approach, it was uncovered that environmental conditions tend to have a greater impact on metabolomic composition …

Evaluating Inorganic Feed Phosphate Type And Further Potential Of Phytase Supplementation Using A Commercial Broiler Model, Angela Elsie Lamp

Graduate Theses, Dissertations, and Problem Reports (ETD)

Optimizing feed formulation of poultry diets may be achieved by proper utilization of nutrients and feed additives. This will provide a less expensive and nutrient efficient diet to the bird. An experiment was conducted to evaluate early broiler performance, tibia mineralization, and mineral digestibility of broilers fed diets that differed in inorganic feed phosphates (IFP) but that were formulated to be either similar in dietary non-phytate phosphorus (nPP) and calcium to phosphorus ratio (Ca:P), total mineral content, or calculated prececal digestible phosphorus (CPDP). Dicalcium phosphate (DCP), monodicalcium phosphate (MDP), monocalcium phosphate (MCP), and defluorinated phosphate were used in formulations with …

Environmental Contaminants, Parasitism, And Neoplasia In White Perch Morone Americana From Chesapeake Bay, Usa, Mark Arnold Matsche

Graduate Theses, Dissertations, and Problem Reports (ETD)

White perch are an abundant demersal fish species in freshwater and oligohaline habitats of the Chesapeake Bay. An avoidance of salinity > 12-15 ppt generally restricts the distribution and movements of fish to within tributaries in the mid to lower Bay, which over time has resulted in the formation of at least three separate stocks in Chesapeake Bay. Sub-populations of white perch that are partially isolated may serve as sentinels of the conditions or stressors in the tributaries in which they reside. Fish are exposed to a variety of environmental contaminants and other anthropogenic stressors that can vary in magnitude based …

Regional Variation On Loanword Adaptation In Japanese, Yuki Hattori

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis examines the variations of loanword abbreviations in Japanese dialects. When adopting foreign words into Japanese, phonological grammar is applied creating loanwords. When loanwords are introduced, Japanese phonological rules determine how to pronounce the new words; Japanese truncation styles are applied to shorten and abbreviate loanwords. Much like native Japanese words, regional variations can be observed in loanword abbreviations. In order to discover how variations are created, this study compares two dialects: the eastern Japanese dialect (standard dialect) and the western Japanese dialect (Kansai dialect). Despite a recent decrease in popularity, the Kansai dialect is still one of the …

Frontal Brain Injury: Effects On Flexibility, Impulse Control, And Attention, Christopher Matthew O'Hearn

Graduate Theses, Dissertations, and Problem Reports (ETD)

Traumatic Brain Injury (TBI) is defined as an impact to the head, penetration of the skull, or rapid deceleration of the skull, resulting in an alteration of brain function or neurological deficit. Cognitive deficits are common following TBI and often go unresolved due to a lack of effective treatments. These deficits often perseverate into the chronic post injury phase, so the development of rehabilitative strategies is imperative. Behavioral flexibility, impulse control, and attention are a few cognitive processes that are commonly affected by TBI. The current research compares these processes between rats with and without a severe frontal brain injury …

It’S All Fun And Games Until Somebody Dies: Grief, Mortality Salience, And Coping In Meaningful Permadeath, Mckay Steven West

Graduate Theses, Dissertations, and Problem Reports (ETD)

Because part of the enjoyment of video game experiences is rooted in their ability to afford players to fail but still reattempt gameplay with relatively little consequence, the appeal of playing games with permadeath seems paradoxical. This dissertation proposed that players’ motivations for playing these games with permadeath stem from an enhanced sense of appreciation garnered by players through the meaningfulness of permanent character death, rather than just through simple, hedonic enjoyment. Enhanced appreciation was expected to arise from permadeath through the grief players experienced toward the loss of their characters and through their contemplation of their own mortality. Grief …

C-Jun Nh2-Terminal Kinase Signaling Controls Cellular Mechanisms Of Guided Cortical Interneuron Migration, Skye Eleanor Smith

Graduate Theses, Dissertations, and Problem Reports (ETD)

The cerebral cortex is an intricately organized brain structure responsible for high-level functions including sensory perception, movement, memory, language, and cognition. During corticogenesis, cortical excitatory neurons and inhibitory interneurons migrate from their respective progenitor zones into the developing cerebral cortex, deposit in the correct cortical layer, and establish connections with their appropriate synaptic partners. The balance between excitation and inhibition is critical for cortical circuitry development and function. Aberrant migration of inhibitory interneurons can alter the formation of cortical circuitry and lead to several neurodevelopmental disorders including epilepsy, autism spectrum disorder, and schizophrenia. Therefore, elucidating the mechanisms responsible for inhibitory …

Navigation Under Obstacle Motion Uncertainty Using Markov Decision Processes, Jennifer Quyen Nguyen

Graduate Theses, Dissertations, and Problem Reports (ETD)

In terms of navigation, a central problem in the field of autonomous robotics is obstacle avoidance. This research explores how to navigate as well as avoid obstacles by leveraging what is known of the environment to determine decisions with new incoming information during execution. The algorithm presented in this work is divided into two procedures: an offline process that uses prior knowledge to navigate toward the goal; and an online execution strategy that leverages results obtained offline to drive safely towards the target when new information is encountered (e.g., obstacles). To take advantage of what is known offline, the navigation …

Fast Decision-Making Under Time And Resource Constraints, Kyle Gabriel Lassak

Graduate Theses, Dissertations, and Problem Reports (ETD)

Practical decision makers are inherently limited by computational and memory resources as well as the time available in which to make decisions. To cope with these limitations, humans actively seek methods which limit their resource demands by exploiting structure within the environment and exploiting a coupling between their sensing and actuation to form heuristics for fast decision-making. To date, such behavior has not been replicated in artificial agents. This research explores how heuristics may be incorporated into the decision-making process to quickly make high-quality decisions through the analysis of a prominent case study: the outfielder problem. In the outfielder problem, …

Nutrient Cycling-Tree Species Relationships In Appalachian Forests, Philip Michael Crim

Graduate Theses, Dissertations, and Problem Reports (ETD)

Since the colonization of North America by Europeans, ecosystems in Appalachia and across the continent have been in a prolonged state of flux. Areas particularly rich in natural resources, such as Appalachia, have historically borne the brunt of these swift changes, often with devastating consequences. Downwind of much of the power generation facilities of the Ohio Valley, Appalachian forests have been geographically predisposed to high rates of acidic deposition, a circumstance mitigated by the passage of Clean Air Legislation beginning in the 1970s. Nevertheless, decades of elevated nitrogen (N) and sulfur (S) inputs had a profound impact on the ecology …

The Effects Of Acute Photobiomodulation On Anaerobic Exercise Performance, Jillian Danielle Forsey

Graduate Theses, Dissertations, and Problem Reports (ETD)

Optimal performance in sport requires a balance between training stress and recovery. Therapeutic modalities that allow athletes to maintain this balance while training hard are in high demand, but many lack research. Photobiomodulation is a red and near-infrared light therapy that is proposed to enhance exercise performance and hasten recovery. The purpose of this study was to examine the effects of acute whole body photobiomodulation, applied pre-exercise, on anaerobic exercise performance.

Forty-eight healthy, active subjects participated in this single-blind, crossover study. Subjects visited the lab three times to complete a repeat Wingate test, with one week between each visit. All …

Tobacco Cessation In A Dental School Setting, Kerri T. Simpson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction

Tobacco use remains the single largest preventable cause of death in the United States. Currently, the prevalence of tobacco use is 20.7% in adults (≥18 years old) and 31.2% among high school students. According to various studies, over 60% of Americans want to quit tobacco, but it takes a person several attempts to quit before they are successful. There is limited data in the literature that discusses the effectiveness of tobacco cessation programs in US dental schools. Therefore, information on the effectiveness of a tobacco cessation program in a dental school setting could benefit this state and the problem …

Becoming The Lion's Historian, Khadija-Awa Diop

Graduate Theses, Dissertations, and Problem Reports (ETD)

This professional project examines the ways in which French colonial documentaries were used in conjunction with governmental legislation to enforce dominant narratives and repress marginalized perspectives about the nature of colonialism and the roles of the French and West Africans in its execution. Through the limitations and powers of documentary filmmaking, this project explores the ways in which counter narratives can allow media professionals today to remedy the one sided dominant narratives about marginalized communities that have existed for decades. The culmination of this project is in the creation of a documentary treatment and sizzle reel that will be the …

Recalling The Georgic: Land, Labor, And Literature In American Ecological Consciousness, Sam Horrocks

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation argues that environmentalism and the environmental humanities are limited by an overinvestment in the discursive mode of pastoral, which provides the ecological logic of industrial urbanization by viewing the environment from the perspective of a leisured and alienated spectator. The pastoral mode enables environmental injustice by separating the realms of ecology and economy through a conventional elision of issues of labor and economics, rendering environmentalism unable to effect change within the spheres most important to ameliorating the pollution crisis. The pastoral mode thus frustrates the overarching goal of ecocriticism and environmentalism: we seek an ontological reunion of nature …

Bullets, Breeding, And Biodiversity: An Analysis Of Trophy Hunting In South Africa's Green Wildlife Economy, Dave E. Knieter

Graduate Theses, Dissertations, and Problem Reports (ETD)

Using a political ecology framework, I explore the relationship between international trophy hunting and South Africa’s private wildlife ranching industry. I interrogate the intersection of colonialism, capitalism, and conservation, which at its nexus are the discourses, policies, and logics that greenwash the production of nature. The proceeding chapters highlight a number of specific themes that problematize the neoliberalization of nature, including (i) the contradictions of imposing a market value to nonhumans; (ii) the operationalization of socioeconomic and environmental frameworks to justify trophy hunting and the breeding of nonhumans for profit; (iii) the use of African landscape and wildlife imagery to …

Behavioral Functions Of Stimuli Correlated With Transitions Between Rich And Lean Schedules Of Reinforcement, Cory Whirtley

Graduate Theses, Dissertations, and Problem Reports (ETD)

Disruptions in operant behavior in the form of extended pausing reliably occur when there is a discriminable transition from a relatively rich schedule of reinforcement to a relatively lean schedule (i.e., a rich-lean transition). The present experiments assessed the reinforcing and aversive functions of the stimuli correlated with the transitions between rich and lean schedules using observing and escape procedures. In both experiments, pigeons’ key pecks were reinforced with food on a compound schedule with two FR components. Completing the FR in the rich component produced a large reinforcer; completing the FR in the lean component produced a small reinforcer. …

Developmental Mechanisms For The Diversification Of Polyphenic Morphs In The Head Horn Of Onthophagine Beetles (Coleoptera: Scarabaeidae Onthophagus Taurus): Plasticity Through Nutrition, Logan Paul Zeigler

Graduate Theses, Dissertations, and Problem Reports (ETD)

Developmental plasticity is the phenotypic variation between organisms that is caused by environmental interactions affecting the developmental systems of organisms. The research focused primarily on nutrition-responsive developmental plasticity. In this research we used the nutritionally determined head horn development of Onthophagus taurus to better understand the developmental mechanisms and genetic underpinnings of nutrition-responsive trait development. We focused specifically on altering the availability of specific nutrition-related primary metabolites, cholesterol and palmitic acid, identified in the activity of The Hedgehog pathway, a critical pathway in head horn development. By altering diet composition using cholesterol, reducing transcript expression of an acyltransferase gene, rasp …

Assessment Of Protein Quality, Lipid Metabolism, Hepatic Transcriptome And Safety Of A Silver Carp (Hypophthalmichthys Molitrix) Derived Sarcoplasmic Protein Powder., Derek Cole Warren

Graduate Theses, Dissertations, and Problem Reports (ETD)

Fishery resources are currently operating either near optimal yield or at levels with elevated risk for fish stock depletion. A solution for overcoming limitations of natural fish resources is through utilization of less desirable fish species and fish processing by-products. Water-soluble sarcoplasm proteins consist of 25 – 30% of protein in carp, are lost in wash water during processing and can be recovered and freeze-dried to produce a protein-rich powder (CSP). The objective of this project was to evaluate the protein quality and safety of CSP, assess diets consisting of CSP or commercial milk proteins effects on lipid metabolism, and …

The Wiring Logic Of Identified Serotonergic Neurons Across Olfactory Networks In Drosophila, Kaylynn E. Coates

Graduate Theses, Dissertations, and Problem Reports (ETD)

Serotonin is a ubiquitous neuromodulator that confers flexibility in networks to modulate a wide array of behavioral and physiological processes. However, due to the complexity and heterogeneity of serotonergic systems, it has been challenging to determine the patterns of connectivity as well as the physiological contexts that influence individual serotonin neurons. In this dissertation, I use two serotonergic neurons which innervate the Drosophila olfactory system, the CSDns, as a model to explore these broad questions comprehensively using anatomical approaches. I first show that the CSDns have distinct connectivity relationships with populations of antennal lobe principal olfactory neurons and that their …
