Extended Pseudo Invariant Calibration Site-Based Trend-To-Trend Cross-Calibration Of Optical Satellite Sensors, Prathana Khakurel

Electronic Theses and Dissertations

Satellite sensors have been extremely useful and are in massive demand in the understanding of the Earth’s surface and monitoring of changes. For quantitative analysis and acquiring consistent measurements, absolute radiometric calibration is necessary. The most common vicarious approach of radiometric calibration is cross-calibration, which helps to tie all the sensors to a common radiometric scale for consistent measurement. One of the traditional methods of cross-calibration is performed using temporally and spectrally stable pseudo-invariant calibration sites (PICS). This technique is limited by adequate cloud-free acquisitions for cross-calibration which would require a longer time to study the differences in sensor measurements. …

Detection Of Change Points In Pseudo-Invariant Calibration Sites Time Series Using Multi-Sensor Satellite Imagery, Neha Khadka

Electronic Theses and Dissertations

The remote sensing community has extensively used Pseudo-Invariant Calibration Sites (PICS) to monitor the long-term in-flight radiometric calibration of Earth-observing satellites. The use of the PICS has an underlying assumption that these sites are invariant over time. However, the site’s temporal stability has not been assured in the past. This work evaluates the temporal stability of PICS by not only detecting the trend but also locating significant shifts (change points) lying behind the time series. A single time series was formed using the virtual constellation approach in which multiple sensors data were combined for each site to achieve denser temporal …

A Hydrologic Climate Study For An Arid Region, Ali Alsubeai

Electronic Theses and Dissertations

Water is the most precious natural resource in arid regions due to the limitation of water resources, expanding population, and increasing volumes of industrial and domestic waste. The purpose of this research was to evaluate methods to estimate water quantity in an arid region. The research consisted of three separate studies. In the first study, hydrologic models used to estimate water quantity were evaluated for suitability of use in arid regions. Most hydrologic models that have been used in arid regions were originally developed for humid regions. Rainfall events in arid regions can be characterized as short-term, high intense rainstorms …

Revitalization In The Alabama Black Belt: Cultivation Of A New Civic Hegemony In Rural Main Street America, Martha Grace Lowry Mize

Electronic Theses and Dissertations

One Alabama Black Belt community has sought to re-imagine itself as a future affluent space for new families, tourists, and diasporic communities—despite regional challenges—by supplanting traditional discourses and centering a new civic hegemony within local revitalization efforts. This research and thesis draws upon qualitative ethnographic methods: participant observation and interviews conducted in Marion, Alabama. Located in Perry County, Marion has approximately 3,000 inhabitants, the majority of whom are African-American. Marion was designated as a Main Street Community (June 2017) and began a series of revitalization initiatives to increase community pride and project confidence about future growth. The National Main Street …

Broccoli Over Brownies: Factors Affecting Healthy Food Choices For Low Income Residents Of Sioux Falls, South Dakota, Aileen Patricia Profir

Electronic Theses and Dissertations

The world is on the cusp of a nutritional crisis: malnutrition, in all its forms, now directly affects one in three persons on the planet. Chronic malnutrition is closely associated with a wide range of public health issues such as stunted growth, increased incidence of disease, school or work absences, and obesity. Access to proper nourishment for food insecure individuals is often evaluated as a measure of distance to market, yet a causal relationship between proximity to food resources and improved health outcomes is unclear. Multiple dimensions of food access influence fruit and vegetable consumption for those who are food …

Classification And Evaluation Of Extended Pics (Epics) On A Global Scale For Calibration And Stability Monitoring Of Optical Satellite Sensors, Juliana Maria Fajardo Rueda

Electronic Theses and Dissertations

As targets for the calibration and monitoring of optical satellite sensors, historically stable areas across North Africa have been used, known as Pseudo Invariant Calibration Sites PICS. However, two major drawbacks exist for these sites; first is the dependency on a single location to be always invariant, and second is the limited amount of observation achieved using these sites. As a result, longer time periods are needed to construct a dense data set to assess the radiometric performance of on-orbit optical sensors, and be convinced that the change detected is sensor-specific rather than site-specific. This work presents a global land …

Using New And Long-Term Multi-Scale Remotely Sensed Data To Detect Recurrent Fires And Quantify Their Relationship To Land Cover/Use In Indonesian Peatlands, Yenni Vetrita

Electronic Theses and Dissertations

Indonesia has committed to reducing its greenhouse gases emissions by 29% (potentially up to 41% with international assistance) by 2030. Achieving those targets requires many efforts but, in particular, controlling the fire problem in Indonesia’s peatlands is paramount, since it is unlikely to diminish on its own in the coming decades. This study was conducted in Sumatra and Kalimantan peatlands in Indonesia. Four MODIS-derived products (MCD45A1 collection 5.1, MCD64A1 (collection 5.1 and 6), FireCCI51) were initially assessed to explore long-term fire frequency and land use/cover change relationships. The results indicated the product(s) could only detect half of the fires accurately. …

Use And Improvement Of Remote Sensing And Geospatial Technologies In Support Of Crop Area And Yield Estimations In The West African Sahel, Kaboro Samasse

Electronic Theses and Dissertations

In arid and semi-arid West Africa, agricultural production and regional food security depend largely on small-scale subsistence farming and rainfed crops, both of which are vulnerable to climate variability and drought. Efforts made to improve crop monitoring and our ability to estimate crop production (areas planted and yield estimations by crop type) in the major agricultural zones of the region are critical paths for minimizing climate risks and to support food security planning. The main objective of this dissertation research was to contribute to these efforts using remote sensing technologies. In this regard, the first analysis documented the low reliability …

Quantifying The Impacts Of Land Use, Management And Climate Change On Water Resources In Missouri River Basin, Arun Bawa

Electronic Theses and Dissertations

A location-specific evaluation of hydrological landscape responses concerning past and projected climate and land use land cover (LULC) changes can provide a powerful intellectual basis for developing efficient and profitable agroecosystems, and overcoming uncertain and detrimental consequences of LULC and climate shifts. This dissertation assessed the impacts of land use, management, and climate change on water resources in the Missouri River Basin (MRB) through four specific studies that included: (i) to study the responses of leached nutrient concentrations and soil health to winter rye cover crop (CC) under no-till corn (Zea mays L.)-soybean [Glycine max (L.) Merr.] rotation, (ii) to …

Queer Subculture In The Conservative South: A Study Of Drag Performers In Mississippi, Christina Alison Huff

Electronic Theses and Dissertations

The amount of research on Mississippi LGBTQ communities is scarce. It is well established that ethnographic research on rural Southern queer communities is lacking, and that most LGBTQ research is conducted in metropolitan areas in the northern and western areas of the United States. This study investigates the lives of Mississippi drag performers through films, photographs, and audio documentaries. Specifically, these primary sources demonstrate that many LGBTQ members are thriving in historically conservative rural Southern areas by carving out spaces for their own existence.

Describing The Gut Microbiome Of Amblema Plicata, Lauren Lawson

Electronic Theses and Dissertations

Freshwater mussels are important for nutrient cycling and ecosystem health, as they filter feed on their surrounding water column. This form of feeding makes these bivalves especially sensitive to conditions in their environment. Gut microbial communities (microbiomes) have been recognized as important to both host organism and ecosystem health; however, how microbiomes are organized and influenced is still unclear. In this study, the gut microbiomes of 58 individuals of the freshwater mussel Amblema plicata were compared across two river basins, five rivers, and nine sites in the southeastern USA. Planctomycetes, Firmicutes, and Cyanobacteria were the most common phyla within all …

Blood Money: 12th Century Trade Wars And The Fourth Crusade, Alexander Evgeniy Stalowski

Electronic Theses and Dissertations

The historiography of the Fourth Crusade has neglected long-term macroeconomic developments and its influence on the Fourth Crusade within the Byzantine Empire and the Italian states of Venice, Pisa, and Genoa. It is well-established that the Venetians rerouted the crusading forces to Constantinople which caused political, religious, and economic challenges that altered the Mediterranean world. Yet, the trend of writing on political events and short-term microeconomics and macroeconomics from 1180 to 1204, has done great disservice to the larger trans-regional disputes that engulfed the Mediterranean during the eleventh and twelfth centuries. This thesis will attempt to fill the void of …

By exploring relevant literature and highlighting current initiatives, this work looks at the semantics of food justice and related terms, discusses challenges unique to the Mississippi Delta, and broadly characterizes public health models with the greatest potential for food justice advancement in this region. Pivotal to interpreting food justice not only for the Mississippi Delta or the Global South, but for any community, is a clear understanding …

Nature's Converts: Reading The Land And Nature In The Early American Conversion Narrative, 1727-1831, Cullen Rex Brown

Electronic Theses and Dissertations

This dissertation examines the connections between cultivating the land and cultivating the soul through select readings of early American conversion narratives composed between 1727-1831. Over a century after British Colonists colonized the shores of New England, members of the United Ministers of Boston championed the efforts of their descendants, who both cultivated the land and the Indigenous and new arrived souls emplaced within the North American landscape. As they told their readers in 1727, their dual cultivating efforts were worthy of universal adulation and imitation. And in 1836, the words of Reverend Nahum Gold echoed those of the United Ministers …

Gestures Of Dissent: Self-Fashioning Performance From Southern Women Writers During The Fin De Siécle, Elisa Fuhrken

Electronic Theses and Dissertations

This project explores Southern women writers during the latter half of the nineteenth-century who asserted and crafted a modernized identity by turning to various modes of transgressive performance and performance spaces. For women of the nineteenth-century, this meant extricating themselves from a domestic, sentimental identity and apprehending a more fluid, dynamic type of being. The modes of performance, such as spectatorship, orality, and gesture, allowed these women to express and articulate an alternative feminine identity while also engaging with an embodied epistemology. This thesis looks at three Southern women writers: Sherwood Bonner’s novel Like Unto Like and her travel letters …

Soul Liberation: Black Christian Intellectual Engagement With Black Power, Jemar Tisby

Electronic Theses and Dissertations

Throughout the Civil Rights movement, Black Christians figured prominently as clergy, leaders, and foot soldiers in the struggle. As a result, the presence of Black Christians during this phase of the Black activism is well-documented by historians. During the Black Power era, however, scholars tend to overlook the ongoing presence and significance of Black Christians in the movement. Soul Liberation corrects this omission by studying Black Christian engagement during the Black Power movement of the 1960s and 1970s.

The Perceptions That Um First-Generation College Students Have Regarding The Impact Of Campus Engagement On Their Success At The Institution, Martin B. Fisher

Electronic Theses and Dissertations

First-generation students are often underprepared for college and have lower persistence rates (Balemian & Feng, 2013), and they face a unique set of challenges in their transition to college that many of their peers do not (Pelco, Bell, & Lockeman, 2014). Consistent with national statistics, data obtained from UM’s Office of Institutional Research, Effectiveness, and Planning indicate first-generation students at UM persist and graduate at lower rates than their peers whose parents have a bachelor’s degree.

There are many reasons why first-generation students have lower success rates, and, for some students, a lack of engagement is one of them (Pascarella, …

This paper builds upon a historical framework of school gardening in American public education with particular focus on the connections between school gardens and agricultural education. This study offers a descriptive portrait of contemporary K-12 school gardens in South Dakota. Schools across the state were surveyed about their gardens to gain a better understanding of garden-based teaching in practice both in general education and agricultural …

The Biggest Winner: How Loss Aversion And Negativity Bias Can Increase Affective Polarization, Austin Cutler

Electronic Theses and Dissertations

Affective polarization is on the rise, which makes understanding the origins of it increasingly important. Some work finds that partisan sorting is associated with increased polarization, due to a lack of exposure to conflicting opinions as well as the ease of making generalizations about the opposing side (Iyengar2019-zg). Individuals with more closely aligned ideological and partisan identities are more likely to exhibit hostility towards the other party, and react more emotionally to information that threatens their party or issue stance (Mason2015). The aim of this paper is to analyze how contextual factors, specifically the partisan distribution of an area, can …

Stratigraphy And Geochemistry Of Paleocene-Aged Bauxites From North Mississippi, Timothy Brendan Clark

Electronic Theses and Dissertations

Bauxite is a heavily-mined aluminum ore that forms through the relative depletion of silica to aluminum. In North Mississippi, bauxite occurring within the Upper Midway and Lower Wilcox groups has been the subject of study for over a century. Despite the abundance and duration of research, controversy surrounds the subjects of bauxite genesis and economic value. The last detailed study of North Mississippi bauxite was in the 1980’s, so the goal of this project is to apply newly available technologies and modern hypotheses on bauxite formation to refine and obtain new data. Fieldwork observations yielded pisoliths, horizonation, and possible rhizoliths, …

The Meat Of The Gothic: Animality And Social Justice In United States Fiction And Film Of The Twenty-First Century, Amber Hodge

Electronic Theses and Dissertations

The Meat of the Gothic: Animality and Social Justice in United States Fiction and Film of the Twenty-First Century— situates twenty-first century US gothic narratives in relation to animal studies, even as it illuminates how these narratives interrogate the effects of historic and ongoing global systems of human oppression: slavery, imperialism, and capitalism. Instead of reacting to bias by asserting a claim to a humanity perpetually imbricated in divisions of class, race, and gender, present-day authors and filmmakers create characters who form communities that include nonhuman actors as a means of generating empowerment and critique. My approach to these narratives …

Economic Development Policy And Economic Growth In The American States, Mohammed Shariful Islam

Electronic Theses and Dissertations

The American states routinely adopt various economic development policies but those policies do not always contribute to economic growth in the state. Scholars identify several reasons to explain why the policies do not always work. First, policies that do not address market demand; rather, provide economic incentives to bring inward industrial investments do not contribute to economic growth because the cost it takes to create jobs by such industrial recruitments is too high. Second, policies that are adopted out of inertia chosen from traditionally practiced policies do not work because they are not evaluated for their effectiveness in terms of …

Teachers Perceptions Of Using Young Adult Literature As A Catalyst To Discuss Social Justice In Mississippi Classrooms, Shimikqua Ellis

Electronic Theses and Dissertations

ABSTRACT Educational inequality and racial injustice are serious challenges that educators continue to face. More educators are seeking social justice teaching practices and implementing culturally responsive pedagogies to address systemic inequities in schools. Literary scholars suggest that books should serve as mirrors and windows for readers. Diverse young adult literature is a powerful medium through which social injustices, racial inequities, and social problems can be addressed in the classroom. This study is designed to help teachers create a more inclusive classroom through using adolescent literature. Four teachers in diverse schools throughout Mississippi used The Hate U Give by Angie Thomas …

Designing For Democracy: How Democratizing States Design International Organizations, Marissa Wyant

Electronic Theses and Dissertations

Building on work by Paul Poast and Johannes Urpelainen that suggests that democratizing states are more likely to form new international governmental organizations rather than join existing ones, I ask the question: how do these states design the organizations they form, and how do those design choices compare to the choices made by consolidated democracies and by nondemocracies? I focus on three design choices made by states regarding membership constraints, voting procedures, and dispute resolution processes. By comparing and analyzing founding charters, I find that democratizing states were more likely to constrain access to membership into these organizations to regional …

Sea Level Rise Impacts On The City Of Cape Coral, Southwest Florida From 2020 To 2050, Jawata Afnan Saba

Electronic Theses and Dissertations

Sea level rise, a consequence of global climate change, has been affecting the U.S. coasts with flooding and exacerbated storm surges. Florida is highly vulnerable because it has low-lying topography and coastlines on both the Atlantic Ocean and the Gulf of Mexico. The City of Cape Coral, Southwest Florida, is known as a ‘waterfront wonderland’ with 400 miles of canals that provide waterfront property to the residents. Most of the canals are navigable, and many have access to the Gulf of Mexico. The city is vulnerable to sea level rise because of its canals, site between the Matlacha Pass and …

Quantification Of Climate Variability And Extreme Events In The Great Plains, Angelinah Ntsieng Rasoeu

Electronic Theses and Dissertations

Climate variability and extreme events continue to worsen resulting in significant impacts to society and the environment. Quantifying precipitation variability, streamflow, and extreme events at local scale is crucial for local planning and management due to spatial and temporal precipitation variability which influences streamflow and thus, water resources. This study uses statistical tools to analyze 1895-2019 (125 years) of historical precipitation data to examine how long-term precipitation varies annually, seasonally, and monthly, and create climate classifications. The results show that annual precipitation is increasing linearly over time ranging from 13.2 in (1976) to 43.1 in (2010) and 5 climate classes …
