New Reports Of Smilodon And Panthera From North American Cave Sites With Reviews Of Taxonomy, Biogeography, And History, Matthew Bushell

Electronic Theses and Dissertations

In this study, three new reports of large felids from the Pleistocene are presented and discussed. A single partial left dentary from Jawbone Cave represents the first confirmed presence of S. fatalis in east Tennessee and was sampled for radiocarbon dating. Wind Tunnel and Chilly Bowl Cave are among the first records of P. onca to be identified confidently from Arkansas. Chilly Bowl Cave also produced two trackways attributable to Panthera sp., one set potentially belonging to P. atrox. In addition to the description of these remains and the caves they were found in, taxonomic histories for both S. fatalis …

Exploring Sexual And Reproductive Health Care In Central Appalachia Through The Experiences Of Transgender And Gender Non-Binary People, Chase Harless

Electronic Theses and Dissertations

Background: Transgender or nonbinary (TNB) individuals in the United States experience higher rates of sexual and reproductive health disparities when compared to their cisgender counterparts, along with lower access to care. TNB people in the south experience higher rates of disparities. Societal, interpersonal, and individual barriers contribute to these disparities in the TNB population. However, there is a paucity of research examining the sexual and reproductive health experiences of TNB people living in Central Appalachia.

Flood Hydrology In Tropical Coastal Catchments: Linking Watershed Dynamics To Mangrove Sedimentation, Shannon L. Jones

Electronic Theses and Dissertations

Coastal flooding is expected to be more frequent and severe from amplified flooding from sea level rise (SLR) and upstream anthropogenic activity, particularly in tropical regions. Improved hydrologic modeling and characterization are needed to better understand, predict, and manage flooding where these amplifications are expected. Yet tropical catchments are often ungauged or have limited hydrogeomorphic data. Thus, locally calibrated models that incorporate local knowledge and alternative data can be used to provide greater information. This doctoral dissertation quantifies relationships between land use, precipitation, discharge, and downstream sediment accretion in a representative ungauged catchment using a locally calibrated rainfallrunoff model validated …

Permanent Supportive Housing (PSH) is a formal intervention which seeks to offer stability and support to young people. This three-manuscript dissertation uses community-engaged mixed methods to understand sense of community, sense of place, and third places among young adults in PSH in Grand Junction, Colorado.

The first manuscript used longitudinal mixed methods to understand how PSH residents’ (N = 27) sense of community shifts over 1.5 years of living in PSH. We found that residents’ sense …

A Participatory Drone Mapping And Critical Physical Geography Of Water Security For Irrigation In Northern Ghana, Dinko Hanaan Dinko

Electronic Theses and Dissertations

Dam discourse frequently incorrectly assumes that their emergence unilinearly translates to an expansion of economic opportunities while not considering how dams become sites for the reproduction of inequality and injustice. This dissertation investigates how the politics of irrigation water access are nested in a complex web of physical materialities of the 'natural' environment and power relations, with lived consequences on differentiated social identities in semiarid Ghana. The research draws on transdisciplinary perspectives from political ecology, embodiment, critical physical geography, and mixed methods, including interviews, focus group discussions, surveys, participatory drone mapping, and laboratory analysis of soil biochemical properties.

Water Literacy In Drought-Prone Regions: Case Studies From Aurora, Colorado, Usa And Cape Town, Western Cape, South Africa, Meghan Mccarroll

Electronic Theses and Dissertations

Water managers around the world must reevaluate their approach to water security as challenges continue to grow. Supply-focused paradigms that aimed to capture, control, and commodify water resources are increasingly unreliable and often depend on environmentally and socially damaging practices. Of particular concern are regions experiencing climate shocks and aridification from rising global temperatures. In order to stretch limited water resources using equitable water policies, conservation programs, and alternative water sourcing, water managers must invest in a water literate citizenry. Water literacy is the culmination of water-related knowledge, attitudes, and behaviors. The benefits of a water literate citizenry abound, including …

Determining Background Deep-Time Critical Zone Conditions In Mississippi Preceding The Onset Of Paleocene-Eocene Hyperthermals, Savannah Reese Rathbun

Electronic Theses and Dissertations

Hyperthermals are periods of extremely rapid global warming. In order to understand the magnitude of hyperthermals, a more complete understanding of background conditions must be established. My goal is to study the paleoclimatic conditions that existed prior to the onset of Paleocene- Eocene hyperthermal events in order to establish background conditions. Relatively thick Paleocene and Eocene sedimentary units ideal for this study are present in the Mississippi Embayment (MSE), a major southwest- dipping sedimentary basin in the Gulf of Mexico coastal region of North America. The MSE contains an extensive record of Paleocene strata that were deposited prior to the …

Extended Cross-Referenced Analysis Using Data From The Landsat 8 And 9 Underfly Event, Garrison Gross

Electronic Theses and Dissertations

The Landsat 8 and 9 Underfly Event occurred in November 2021, where Landsat 9 flew beneath Landsat 8 in the final stages before settling in its final orbiting path. An analysis was performed on the images taken during this event, which resulted in a cross-referenced with uncertainties estimated to be less than 0.5%. This level of precision was due in part to the near-identical sensors aboard each instrument as well as the underfly event itself, which allowed the sensors to take nearly the exact same image at nearly the exact same time. This initial calibration was applied before the end …

Quantitative Change Analysis Of Undisturbed Lands In Eastern South Dakota: 2012-2021, Riley W. Wollschlager

Electronic Theses and Dissertations

The actual rate of loss of undisturbed prairie and woodland in eastern South Dakota is unknown, and the landscape composition of the region continues to change. Undisturbed land is land with no proven prior cropping or other disturbance history. Agriculture, development, recreation, and other land use practices create disturbances resulting in the further conversion of undisturbed prairies and woodlands. Previous work by South Dakota State University (SDSU) quantified the remaining undisturbed land in eastern South Dakota as of 2012 (Bauman et al 2016). Farm Service Agency (FSA) common land unit (CLU) and National Agricultural Imagery Program (NAIP) imagery were the …

The Development Of Dark Hyperspectral Absolute Calibration Model Using Extended Pseudo Invariant Calibration Sites At A Global Scale: Dark Epics-Global, Padam Bahadur Karki

Electronic Theses and Dissertations

This research aimed to develop a novel dark hyperspectral absolute calibration (DAHAC) model using stable dark targets of "Global Cluster - 36" (GC-36), one of the clusters from "300 Class Global Classification." The stable dark sites were identified from GC-36 called "Dark EPICS-Global" covering the surface types viz; dark rock, volcanic area, and dark sand. The Dark EPICS-Global shows a temporal variation of 0.02 unit reflectance. This work uses the Landsat-8 (L8) Operational Land Imager (OLI) , Sentinel-2A (S2A) Multispectral Instrument (MSI) , and Earth Observing One (EO-1) Hyperion data for the DAHAC model development, where well-calibrated L8 and S2A …

It’S Just A Way Of Life: A Symbolic-Interactionist Approach To Inequalities In The Contemporary American South, Angela Rankin

Electronic Theses and Dissertations

The contemporary American South is characterized by significant inequalities that are deeply- embedded into the social fabric of the region. These inequalities are dictated by cultural and social dynamics that have shaped the Southern region over time; however, they are reinforced daily through the individual agency of Southern social actors. This thesis aims to analyze Southern inequalities through a symbolic-interactionist focused lens and data collected from semi-structured, qualitative interviews conducted with over 70 White Southerners in two places within the American South- Oxford, MS, and Memphis, TN. In this thesis, I argue that White Southern actors actively use their individual …

Oh Men Of Justice! Petitioning In Protectorate Bahrain 1919-1939, Ashleen Williams

Electronic Theses and Dissertations

In 1934, Bahraini petitioners wrote to the Ruler of Bahrain to demand protection for the rights of individuals. The petition was not the first, nor was it the last, to demand rights in Bahrain during the interwar period. This study examines petitioning and claim-making in protectorate Bahrain. A close reading of petitions submitted by different Bahrain communities from 1919 to 1939 demonstrates Bahrain was shaped by multiple competing and cooperating priorities. This study identifies three stages of petitioning in the interwar period: petitioning for protection, petition for rights, and nationalist petitioning. Using a framework of jurisdictional ambiguity, the dissertation shows …

Reimagining The Radical: Gender, Genre, And Anti-Fascism In Women's Writing At Mid-Century, Allison Nick

Electronic Theses and Dissertations

This dissertation looks at the work of four women writers—Martha Gellhorn, Elizabeth Bowen, Pearl S. Buck, and Rebecca West—who are united in their transnational commitment to critiquing the global rise of fascism and the fraught democratic imperatives of their own countries. “Reimagining the Radical” focuses on the temporal gap between modernism and postmodernism and is inspired by work from scholars like Marina MacKay, Lyndsey Stonebridge, and Beryl Pong to claim and define mid-century literature. By rethinking the bounds of modernism, “Reimagining the Radical” also seeks to fill the gaps in feminist history—between the suffragism of the early 20th century and …

Houses That Try To Be Haunted: A Look At Ursuline Convent And The Lalaurie Mansion, Kallye Virginia Smith

Electronic Theses and Dissertations

New Orleans, Louisiana, has a reputation for being one of the most haunted cities in America. Two of the most supposedly “haunted” buildings in the city are the Ursuline Convent, said to be home to vampires, and the Lalaurie mansion, said to be home to ghosts. Whether or not these spaces qualify as “haunted” is irrelevant; what this thesis concerns itself with is why these spaces are still being discussed today. Both contain a long and storied past that date back to the early days of New Orleans, with the convent being around as early as the 1730s and the …

The Presence And Prevalence Of Underqualified High School Science Teachers In Mississippi, Shelby Ann Watson

Electronic Theses and Dissertations

With growth in STEM postsecondary programs and careers positioned as a national priority, ensuring that K-12 science classrooms are staffed with highly qualified teachers is an important step towards building student interest in STEM and preparing students for STEM careers. However, previous studies of out-of-field teaching have indicated that schools and districts across the country are hiring large numbers of underqualified teachers to fill high-needs positions, such as secondary science and mathematics. Complicating the issue is the fact that data regarding teacher shortages, vacancies, and underqualified teaching are often incomplete or inaccessible. Prior studies have found that underqualified teaching is …

Voices From Below: The Politics Of Leprosy Control In Southeastern Nigeria, 1926-1960, Odinakachukwu Kingsley Eze

Electronic Theses and Dissertations

Leprosy was an endemic disease in colonial Southeastern Nigeria but became an epidemic between the 1920s and 1940s. Unlike malaria and sleeping sickness, its endemicity did not impede European penetration at the dawn of the twentieth century. However, its spread across Nigeria intensified during colonial rule, with acute prevalence in regions hitherto prone to the disease. Therefore, from the 1920s to 1960, Southeastern Nigeria became the epicenter of British policies tailored towards preventing, curing, and eradicating leprosy disease in Nigeria. Existing research has established the involvement of different actors in this course–including Christian missionaries, colonial officials, specialized agencies, and international …

Psychometric Properties Of The Spanish Ucla Ptsd Reaction Index For Dsm-5€“Brief Form In Puerto Rico Following Hurricane Maria, Evan Edward Rooney

Electronic Theses and Dissertations

Trauma exposure among youth is a significant public health issue and is associated with psychiatric symptoms and impaired functioning. Natural disasters, such as hurricanes, have become an increasingly salient source of traumatic exposures for youth. However, not all youth exposed to traumatic experiences go on to develop posttraumatic stress symptoms or other maladaptive reactions. Given the high need for psychological support and low resource context engendered by hurricanes, efficient and evidentiary tools for assessing risk are needed to effectively identify youth most in need of services. The present study will use a sample of 96,108 Puerto Rican youth (Grades: 3-12; …

A Storyteller's Remove: Place-Noticing In Welty's Disturbed Landscapes, Lucy Gaines

Electronic Theses and Dissertations

Mississippi author Eudora Welty’s particular attunement to her characters’ place and time earned her canonization among southern authors bound by a peculiar sense of place. Our understanding of place, though, is rapidly evolving, spreading theoretical roots across disciplines and striving to keep up with global environmental change. Adopting frameworks from ecology, sociology, and comparative literature, this work seeks out the common denominators between Welty’s sense of place and our present perspectives, training our eye to notice relationships previously unconsidered. Unmistakable throughlines in Welty’s writing and photography offer fertile grounds for tracing place theory through visual and critical analysis, and find …

Methods For Improving Potassium Fertilizer Recommendations For Corn In South Dakota, Andrew J. Ahlersmeyer

Electronic Theses and Dissertations

Corn (Zea mays L.) is a vital commodity in South Dakota’s agricultural sector. Optimal corn production occurs when there are sufficient mineral nutrients in the soil, especially potassium (K). Applications of K fertilizer are used when soil test K (STK) levels are deficient. Therefore, producers need reliable, thoroughly tested fertilizer recommendations to make profitable decisions and maintain environmental stewardship. South Dakota K fertilizer recommendations have not been updated in nearly 20 years. Simultaneously, changes in corn genetics, management practices, and climate patterns suggest that the critical soil test value (CSTV) for STK may have shifted in that same time frame. …
