“Dialogical Offense:” A Postcolonial Womanist Deconstruction Of The Colonial Experience Of African American Women Through U.S. Institutional Apparatus Known As Criminal Justice Policy, April Michelle Woodson

Electronic Theses and Dissertations

The Black female experience in the United States is a colonized existence. This project’s analysis is specific to the North American U.S. geographic space and is not a diasporic project. Black women suffered from the greatest increase in the percentage of inmates incarcerated for drug offenses in the 1980’s and 1990’s which is the period of criminal justice policy formation and implementation on which this project is focused.

This project is uniquely situated in the overlap between womanist ethics and postcolonial feminist imagination and extends scholarship in both discourses by showing that there is an interwoven line between the colonial-to-contemporary …

Urban Green Space: Mitigator Or Multiplier Of Inequality In The Denver Metropolitan Area?, Joshua Charles Baldwin

Electronic Theses and Dissertations

Studies have shown that communities of color and low-income populations are likely to live in neighborhoods that lack access to quality green spaces, unable to directly benefit from the environmental, recreational, and cultural services they provide. The goal of this research was to determine if the green space inequality patterns seen globally and nationally exist in the Denver Metropolitan Area. Using an existing green space dataset, ecosystem services fieldwork, GIS digitizing, and bivariate correlation analysis I uncovered numerous green space inequalities based on proximity, acreage, and quality. Key findings included 1) Lakewood’s Hispanic and less-educated populations have relatively little access …

School Facet Through Surrounding Factors: A Geospatial Analysis Of Community Social Capital Impacting Elementary Schools, Sajjid Budhwani

Electronic Theses and Dissertations

School performance rating is an important factor which not only provides a quick snapshot of how the students are performing on various measurement indicators but also decides a school’s future course of actions, strategies, resources, and its existence. Despite its significant importance, the school performance framework does not consider where the schools are geographically located and the surrounding factors within which they operate. The researcher of this study presented a landscape of the surrounding factors and its impact on the elementary schools within Denver Public Schools district. In this study, the surrounding factors are geospatially analyzed to determine the extent …

Climate Change And Seed Security Among Smallholder Farmers In Northern Ghana, Michael Biwalib Madin

Electronic Theses and Dissertations

Smallholder agriculture is highly susceptible to climate variability and change. According to recent projections by the Intergovernmental Panel on Climate Change, this sensitivity would likely increase in the coming decades, with more erratic rainfall, prolonged dry periods, shorter growing seasons, and seed germination failures. In the African context, the mechanisms through which these ecological stressors would affect seed security are poorly understood. Drawing upon a case study of semi-arid Ghana, this study examines climate change impacts on seed security among smallholder farmers. It adopts a mixed-methods approach with intensive fieldwork in two farming communities. Conceptually, the study uses a political …

Rock Glacier Development In The San Juan Mountains, Brandon K. Bailey

Electronic Theses and Dissertations

Rock glaciers are common landform features found in deglaciated alpine areas. They are commonly used in the study of climatic changes throughout the Holocene and the reconstruction of neoglacial chronologies. For this research, Schmidt hammer rebound values, weathering rind thicknesses, and the length of lichen thalli diameters found on rock glacier surfaces are used to investigate their effectiveness as field-based relative age determination techniques. Additionally, the ability to identify periods of neoglacial activity using these methods is assessed in two neighboring cirque basins in the San Juan Mountains of Colorado. 41 field sites across three rock glaciers are established with …

Using Multi-Source Data To Assess The Dynamics Of Socioeconomic Development In Africa, Xuantong Wang

Electronic Theses and Dissertations

Frequent and rapid spatially explicit assessment of socioeconomic development is critical for achieving the Sustainable Development Goals (SDGs) at both national and global levels. In the past decades, scientists have proposed many methods for monitoring human activities on the Earth’s surface on various spatiotemporal scales using Defense Meteorological Satellite Program Operational Line System (DMSP-OLS) nighttime lights (NTL) data. However, the DMSP-OLS NTL data and the associated processing methods have limited their reliability and applicability for systematic measuring and mapping of socioeconomic development. This research utilizes Visible Infrared Imaging Radiometer Suite (VIIRS) NTL and the Isolation Forest (iForest) machine learning algorithm …

Genomic And Culturomic Analysis Of Gut Microbiota Function And Salmonella Enterica Expansion, Gavin Fenske

Electronic Theses and Dissertations

Enteric bacteria that are resident in the hindgut of mammals are critical in immune development, digestion, and colonization resistance against pathogens. One of the major pathogens that gut commensals provide resistance against is Salmonella enterica, a major foodborne pathogen capable of infecting almost every warm-blooded animal. Given the interplay between pathogens and commensals in the gut lumen, the gut microbiota of pigs was studied by combining two disparate techniques: shotgun metagenomics and high throughput culturomics. Metagenomics readily identifies major taxa present in samples and can give an estimation to total genetic catalogue from an environment. However, many rare or …

Cold-Water Prey Fish Monitoring And Ecology In Lake Oahe, Nicholas B. Kludt

Electronic Theses and Dissertations

In Lake Oahe, a large mainstem Missouri river reservoir that spans 375 river kilometers in central North and South Dakota, naturalized Rainbow Smelt are the primary forage species for a regionally important Walleye Sander vitreus fishery. Walleye condition in Lake Oahe is highly correlated to Rainbow Smelt relative abundance through time, the latter species being typified by erratic abundance trends since accidental introduction in 1971. Cisco Coregonus artedii were introduced in the early 1990s to augment the cold-water prey base. We evaluated Lake Oahe cold-water prey base monitoring and dynamics through: 1.) a comparison of two hydroacoustic survey designs, 2.) …

Higher Temperatures Have Contrasting Effects On Different Components Of Forage Quality For Caribou In Northern Alaska, Heidi Becker

Electronic Theses and Dissertations

Rising temperatures in the Arctic may affect vegetation, which in turn can affect herbivores, such as caribou, that rely on these plants for forage. Several plant traits contribute to forage quality, including digestibility, nitrogen content, and antiherbivory secondary compounds, but the effect of temperature on these traits individually and combined is unclear. I conducted a three-component study on the effect of higher temperatures on the forage quality of graminoids, deciduous shrubs, and evergreen dwarf shrubs on the North Slope of Alaska. The components included: 1) short and long-term experimental warming, 2) natural temperature variation between south and north-facing slopes, and …

Vicarious Methodologies To Assess And Improve The Quality Of The Optical Remote Sensing Images: A Critical Review, Sakib Kabir

Electronic Theses and Dissertations

Over the past decade, number of optical Earth observing satellites performing remote sensing has increased substantially, dramatically increasing the capability to monitor the Earth. The quantity of remote sensing satellite increase is primarily driven by improved technology, miniaturization of components, reduced manufacturing, and launch cost. These satellites often lack on-board calibrators that a large satellite utilizes to ensure high quality (e.g., radiometric, geometric, spatial quality, etc.) scientific measurement. To address this issue, this work presents “best” vicarious image quality assessment and improvement techniques for those kinds of optical satellites which lacks on-board calibration system. In this article, image quality categories …

Responses Of Land Surface Phenology To Wildfire Disturbances In The Western United States Forests, Jianmin Wang

Electronic Theses and Dissertations

Land surface phenology (LSP) characterizes the seasonal dynamics in the vegetation communities observed for a satellite pixel and it has been widely associated with global climate change. However, LSP and its long-term trend can be influenced by land disturbance events, which could greatly interrupt the LSP responses to climate change. Wildfire is one of the main disturbance agents in the western United States (US) forests, but its impacts on LSP have not been investigated yet. To gain a comprehensive understanding of the LSP responses to wildfires in the western US forests, this dissertation focused on three research objectives: (1) to …

Electronic Theses and Dissertations

Precision agriculture can play an important role in preserving the environment and improving the economic conditions of agricultural producers. This thesis analyzes the determinants of adoption and adoption intensity of precision agriculture technologies in South Dakota. This analysis uses survey data collected from 199 farms distributed over 28 different counties in South Dakota, accounting for approximately 500,000 acres of tillable agricultural land, to (1) discover the factors impacting precision technology adoption; (2) compare and contrast several characteristics among adopters and non-adopters; and (3) develop probit, count, and negative binomial models to determine the significance of explanatory variables impacting precision technology …

Utilizing Rhizospheric And Bacterial Endophytes For Use As Potential Bio-Fertilizers For Sustainable Agricultural Production, Vincent Peta

Electronic Theses and Dissertations

Brassica carinata crop production offers an exciting alternative approach to the energy crisis when looking at novel ways to power our motor vehicles. Bacterial endophytes, while residing in host-plant tissues, offer a wide array of plant growth promotion benefits such as nitrogen fixation to impart nitrogen (N) nutrition, phosphate (P) solubilization to make soil-bound phosphate more mobile in soil for plant uptake, can suppress pathogenic microbes such as fungus and produce plant growth hormones to offset stress incurred by the plant. Previous literature has shown that there is large interest in studying endophytes from economically important crops such as wheat, …

Evolutionary History Of Subterranean Termites In The Geographic And Ecological Context Of The Appalachian Mountains In The United States, Chaz Hyseni

Electronic Theses and Dissertations

Termites in the genus Reticulitermes (Blattodea: Rhinotermitidae) are distributed across the eastern United States, including the southern Appalachian Mountains, a region incredibly rich in biodiversity. The eastern subterranean termite, Reticulitermes flavipes, has been uninentionally introduced to South America and Europe, and is predicted to further expand its geographic range. My goal was to determine how eco-evolutionary processes, operating at both long and short timescales, may have contributed to R. flavipes becoming an invasive species. I examined geographic and environmental influences at historical and contemporary timescales. To do this, I first determined the extent of niche divergence among three geographically overlapping …

Post-Soul Speculation: An Exploration Of Afro-Southern Speculative Fiction, Hilary Word

Electronic Theses and Dissertations

ABSTRACT This thesis is an examination of female authored, post-soul, Afro-Southern speculative fiction. The specific texts being examined are My Soul to Keep by Tananarive Due, Stigmata by Phyllis Alesia Perry, and Sing, Unburied, Sing by Jesmyn Ward. Through exploration of these texts, I posit two large arguments. First, I posit that this thesis as a collective work illustrates how women-authored Afro-Southern speculative fiction based in the post-soul era embodies and champions womanist politics and praxis critical for liberation through speculative elements. Second, I assert that this thesis is demonstrative of how this particular type of fiction showcases the importance …

Instant Schools: The Frenzied Formation And Early Days Of The Mississippi Private School Association, Ernest Flora Iv

Electronic Theses and Dissertations

The founding leadership of the Mississippi Private School Association (MPSA) used individual experience and extensive networking via the Citizens’ Council along with the community’s belief and desire to maintain white-only schools to create a coalition of quickly formed but well-resourced private schools. This political and social clout afforded them the ability to create a large, powerful organization almost “instantly” during a pivotal moment of southern educational history. Scholar Kenneth T. Andrews called the establishment of all-white academies in Mississippi, “a countermovement strategy that floout of the prior history of organized white resistance to the civil-rights movement.” The significance of this …

Electronic Theses and Dissertations

This phenomenological study provides qualitative data in the areas of university image, campus visits, and college choice. The purpose of the study was to examine the value of university image and campus visits in students’ college choices. Twenty matriculated freshmen at the University of Mississippi who participated in campus visits as prospective students and who applied for admission in the months of October through April were selected via purposeful sampling to participate in open-ended interviews about the images that they hold of the university, their campus visit experiences, and their college choice processes. The data collected show that students place …

The Summer Melt Of Rural First-Year Students, Deidre F. Ruffin

Electronic Theses and Dissertations

For many rural students, the future seems limited, and immediate dreams of college attendance appear to be just out of reach. Rural college-bound students are often faced with parental figures with lower educational attainment than the national average, geographic isolation, declining community infrastructure, and negative social dynamics tied to race, class, and income inequality. In this qualitative case study, I will examine the perceived barriers which contribute to summer melt of rural students. Summer melt is a term applied to students that apply to college, are accepted to college, but melt away from the enrollment cycle in the summer months …

Burning With Potential: Understanding The Relationship Between Biochar And Agriculture Of The Northern Glaciated Plains Ecoregion, Kaitlyn Abrahamson

Electronic Theses and Dissertations

Achieving global sustainable agriculture is one of the most incredible challenges of this century, yet many continue to try to solve this problem through the development of precision technologies. Biotechnologies, such as biochar, can perform like a precision technology while protecting agricultural land from soil erosion and fertility loss. The Northern Glaciated Plains ecoregion of the United States is little researched in the benefits from the use of biochar through improved soil nutrient capture and water retention, crop health improvements, and yield increases. The study plot has four sections of corn stover biochar and eight sections of control sections. This …

Biophysical And Socioeconomic Impacts Of Farmer Managed Natural Regeneration In Burkina Faso, Basnewende Brice Fulgence Zoungrana

Electronic Theses and Dissertations

Human actions such as overgrazing, the development of cities at the expense of forests, high intensity and poor agricultural management, and so forth, reduce the resources available for future generations. Because Earth has limited resources, it is important to judiciously use and manage natural resources. Human actions towards nature are the focus of my research in Africa. Increased demands for grazing, agriculture, and ecosystem services led some farmers in developing countries to use unsustainable practices, which may lead to low incomes and poor food nutrition for households. Farmer managed natural regeneration (FMNR) may be a solution to these issues. FMNR …

"Frontline In Mental Healthcare": A Discourse Analytic Clinical Ethnography Of Crisis Intervention Team Trainings For Corrections, Daniel Gruner

Electronic Theses and Dissertations

Throughout the criminal justice system operates a discourse of corrections-reform. This responds to prisoner trauma and resistance by converting them into reforms that strengthen prisons and the larger carceral system while discounting issues of race and class that might undermine institutional legitimacy. The recent adoption of Crisis Intervention Team (CIT) Trainings in corrections is exemplary of corrections-reform discourse. ‘Crisis’ comes from the Greek krinein, meaning ‘to decide.’ The crisis in mental health in prisons involves deciding when to implement what “services” or “programming” for whom.

In this discourse analytic clinical ethnographic study, I focus on the trans-disciplinary corrections …

God, Land, Identity: Divine Fluidity And A Spatial Ecclesiology In West Africa, Clement Kanu

Electronic Theses and Dissertations

African theology is burdened with a major problem of identity, which stems from the lack of African history and memory in African theology. African theologians in the face of the delicate dilemma of creating a theology that is both African and Christian, have fallen into the epistemological compulsion to impose western Christian theological categories as foundational to African theology. Inculturation thus presupposes the already alien space on which the structures of the present ecclesiology is anchored. The result is a peripheral inculturation, a consumer ecclesiology, always seeking to solve its local pastoral problems in accordance with alien incongruous codes and …

Electrospun Fibers And Nanoparticles For The Prevention Of Sexually Transmitted Infections., Kevin Michael Tyo

Electronic Theses and Dissertations

Human immunodeficiency virus-1 (HIV-1) and herpes simplex virus 2 (HSV-2) affect hundreds of millions of people worldwide, with women disproportionately impacted by these infections. Currently, only oral pre-exposure prophylaxis (PrEP) is approved specifically for the prevention of HIV-1, but is challenged with adverse side effects associated with long-term use. Topical delivery platforms, such as gels and films, deliver agents directly to the female reproductive tract, but are limited in providing transient-release. The technology of polymeric electrospun fibers may serve as alternative topical delivery platform to the female reproductive tract. In these studies, we fabricated electrospun fibers comprised of different polymers …

Do Lgbtq-Identified, Postsecondary Writing Instructors Come Out In Their Classrooms?, Michael Baumann

Electronic Theses and Dissertations

My dissertation investigates how and why LGBTQ-identified, postsecondary writing instructors perform intersectional identities in their classrooms. Scholars in the field of rhetoric and composition have examined these critical questions as early as 1974 and several times since. However, oppressive, regressive sexual politics; a maelstrom of contemporary public confessions made possible and prolific through new media; and an increasingly intersectional landscape of queer people all provide exigency to update our coming out conversation. This dissertation is the analytical writeup of a national study that I conducted in 2018. I surveyed approximately 100 LGBTQ-identified postsecondary writing instructors in the United States and …

Towards A Theory Of Human Mobility And Wall-Building: A Comparative Analysis Of Hadrian's Wall And The Iron Curtain., Timothy Heine

Electronic Theses and Dissertations

This thesis contributes a theory on human bordering practices that encompasses diverse types of borders and border experiences. In order to flesh out the factors underlying human wall-building, it is vital to first understand the mobile nature (both as an innate characteristic and adaptive strategy) of our species. A clearer appreciation of the biology of human mobility elucidates the seemingly counterintuitive process of the establishment of cultural boundaries. Such an inquiry into the available inter-disciplinary literature on the topics of human mobility and wall-building reveals much about the manner in which humans interpret and utilize space, the variety of walls …

Childhood Abuse, Religiosity, And Opioid Use: Findings From The National Epidemiologic Survey On Alcohol And Related Conditions Data, James E. Lewis

Electronic Theses and Dissertations

Religiosity is adopting a belief system surrounding concepts of purpose, meaning, and value through an institution that has already defined these concepts prior to the individual member attending and that member’s degree of participation. Religiosity does have protective factors against negative health outcomes. This protective influence was evaluated in this study. Data from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions were examined to learn about the relationship between protective effects of religious participation on substance abuse, and whether this association weakened for individuals who have experienced higher levels of childhood abuse. A binary logistic regression …

Communications And Methodologies In Crime Geography: Contemporary Approaches To Disseminating Criminal Incidence And Research, Mitchell Ogden

Electronic Theses and Dissertations

Many tools exist to assist law enforcement agencies in mitigating criminal activity. For centuries, academics used statistics in the study of crime and criminals, and more recently, police departments make use of spatial statistics and geographic information systems in that pursuit. Clustering and hot spot methods of analysis are popular in this application for their relative simplicity of interpretation and ease of process. With recent advancements in geospatial technology, it is easier than ever to publicly share data through visual communication tools like web applications and dashboards. Sharing data and results of analyses boosts transparency and the public image of …

The Gendering Of Death Personifications In Literary Modernism: The Femme Fatale Symbol From Baudelaire To Barnes, Amanda Mcnally

Electronic Theses and Dissertations

The time of modernity, defined here as 1850-1940, contributed to massive changes in the representation of the feminine in literature. Societal paradigm shifts due to industrialism, advances in science, psychology, and a newfound push for gender equality brought transformation to the Western World. As a result of this, male frustrations revived the ancient trope of the femme fatale, but the modern woman—already hungry for agency, tired of maligned representation in heinous portrayals of skeletons, sirens, and beasts—saw a symbol begging for redemption rather than the intended insult. Women of the nineteenth century infused texture to a two-dimensional accusation that argued …

Online Ultrasound Programs: Program Directors’ Perspective, Ashley Morgan

Electronic Theses and Dissertations

This study focused on opinions of diagnostic medical sonography program directors concerning online education within an allied health field that is clinically based. Although the study is centered around sonography, the findings can be applied to many online programs with clinical aspects. There was limited information concerning online education within a clinically based healthcare field, therefore the literature review focused on distance or online education in general. The participating program directors used online/distance learning terms interchangeably. The objective of this study was to identify factors that attributed to or hindered the progress of an online program in diagnostic medical sonography. …
