Biophysical Factors Affecting Habitat Suitability For Crassostrea Virginica, Jason D. Tilley

Dissertations

Oyster reefs provide a variety of important ecosystem services. However, the mortality rate of eastern oyster, Crassostrea virginica, the dominant species that produces oyster reefs in the northern Gulf of Mexico, is increasing at an alarming rate due to a variety of abiotic and biological factors. I examined how biophysical factors, including the less-studied fatty acid profiles of the suspended particulate matter on which oysters feed, influenced morphometric condition of C. virginica.

I sampled suspended particulate matter (SPM) and oysters in-situ in the western Mississippi Sound, which historically supported the majority of oyster production in Mississippi waters. Sampling …

"Innumerable Small Crafts": Maritime Work In The Estuarian Gulf, 1865-1900, Kevin Grubbs

Dissertations

Maritime historians have argued for a highpoint in maritime activity during the antebellum years. This peak was fed by Americans travelling on tall wooden sailing ships in international trade, in the whaling industries, and as members of the US Navy. The prowess of the American Merchant Marine faded quickly in the middle of the nineteenth century due to military losses during the American Civil War and due to the rise of steamships and steel hulls. This peak was followed by another lesser peak in the Twentieth Century as American ships caught up with technological changes. World War One provided a …

Chronic Stressors, Obesity Pathogenesis, And The Moderating Effect Of Internalized Weight Stigma; A Quantitative, Illinois Study, Karyn Byrne

Dissertations

The obesity epidemic is a ‘wicked’ problem with a complex web of determinants and outcomes. While generally higher for minoritized populations, prevalence rates manifest in surprising, nonlinear patterns. There is no consensus regarding treatment protocols or mitigation efforts, except that current efforts remain largely ineffective. Much research evidence that a profusion of determinants of health support obesity pathogenesis through various physiological processes and mechanisms, including the allostatic load, mitochondria functioning, the gut microbiome, and epigenetics. Intervening to support markers of the allostatic load (immunity, inflammation, and metabolic health) may provide a more effective treatment outcomes than traditional approaches, which tend …

An Investigation Into What Contributes To High Rates Of Preschool Inclusion In Rural Kansas School Districts, Lena Mae Kisner

Dissertations

The inclusion of Kansas preschoolers with developmental delays in general early childhood environments has shown little growth over the past seven years. An initial examination of public data for federal fiscal years 2018, 2019, and 2020 showed inclusion rates in preschools in Kansas public school districts differed by special education administrative configuration (SEAC). Kansas uses three different types of SEACs (i.e., single district, special education cooperative, and interlocal). The special education cooperative (also known as cooperative) and interlocal SEACs had the lowest rates of inclusion in preschools and highest proportion of rural school districts. Despite the lower rates of inclusion …

Purposeful, convenience sampling was used to identify the 10 participants who met the study’s criteria. The semistructured, open-ended interview protocol was developed by a thematic research team of nine peer researchers and …

The Public Muse In Congress: The Punctuation Of American Federal Arts Policy, Elizabeth Deichmann

Dissertations

In 1989, American federal arts policy changed suddenly and drastically when the National Endowment for the Arts (NEA) gained unprecedented attention in Congress for controversial grant awards that supported two visual artists. Prior to this, federal arts policy was an insulated subsystem run by experts applying high art aesthetic standards to grantmaking. Informed by punctuated-equilibrium theory (PET), this investigation of congressional rhetoric shows that Republican policy entrepreneurs during this time effectively set a new, more negative tone about federal arts policy by harnessing conservative culture wars messages. The change in tone preceded federal arts policy’s arrival on the broader congressional …

The Lived Experience Of Afghan Women Refugees In Three Metropolitan Areas Of The Southeastern Us: A Phenomenological Study, Brenda Brown

Dissertations

The global refugee crisis has reached epic proportions. Statistics from the United Nations High Commissioner for Refugees (UNHCR, 2016) reported that in 2015 a record 65.3 million people worldwide, or 39,976 people per day, were displaced, either within their native countries or as asylees and refugees. Afghanistan, from 1980-2014, was the country with the largest number of outgoing refugees and it now ranks third in the world. At the opposite end of the continuum the United States remains the primary host country for refugees, asylees, and resettled refugees from all countries, including Afghanistan. The refugee experience is fraught with challenges …

Enshrining Memory: The Production Of An American Catholic Past, Emily Arledge

Dissertations

American Catholics throughout the nineteenth and twentieth centuries advocated for a canonized American. To promote a candidate, organizers of canonization causes collected objects related to the person’s life and curated exhibits to educate Catholics about the candidate. American shrines became intertwined with creating museums or heritage tourism sites for Catholics to encounter their faith and learn about their place within the nation’s history. This dissertation argues that shrines create an American Catholic public memory by interpreting the lives of saints and potential saints through the American past, situating themselves into a national story, and reproducing a saint’s memory for future …

Environments Of War: The Pacific Northwest And The Waging Of World War Ii, Katherine L. Macica

Dissertations

The Pacific Northwest served an essential role in America’s “Arsenal of Democracy.” Weapons and material produced in the Northwest proved essential to the Allied victory in World War II. These weapons served as agents of destruction abroad, but became agents of transformation for the places in which they were produced. This dissertation examines four of the most important resources and industries in Oregon and Washington to emerge or expand as a result of the war: hydroelectric power, forest products, shipbuilding, and aircraft manufacture. The wartime development of these industries profoundly reshaped the physical and economic landscape of the Pacific Northwest, …

Using Industry Sector Entropy To Predict Economic Community Disaster Resilience: Real-World Verification From The Covid-19 Pandemic, Thomas Brindle

Dissertations

The COVID-19 pandemic has presented an opportunity for disaster science researchers to gain insight into the underlying nature of community resilience through comparing the socioeconomic effects of government action to a common threat across urban population centers of varying economic compositions. For example, the negative effects of the COVID-19 pandemic on employment related to public health mitigation efforts in the leisure and hospitality sector of Las Vegas, NV, during the onset of the pandemic were well publicized. In comparison, other population centers of similar size but with different economic sector composition varied in the degree to which employment were affected, …

Why We Work: Exploring The Relationships Between Work Rewards, Burnout, And Intention To Leave For Professional Nurses, Jacqueline Christianson

Dissertations

Nurse burnout leads to attrition from hospital nursing positions and the nursing profession prior to typical retirement age. Yet some nurses choose to stay despite burnout. Previous research indicates that nurses stay due to the rewards they receive from work but the relationships between different types of work rewards, work-related burnout, and intention to leave are poorly described. The ability to implement or execute altruistic behaviors may also represent an under-recognized work reward. Thus, the purpose of this study is to investigate the relationships between work rewards, work-related burnout, and intention to leave nursing positions and the nursing profession and …

A Quantitative Study Of Perceived Fitness And Nutrition Levels Of Secondary Educators In Relation To Their Overall Job Satisfaction Program At A Private Midwestern University, Jessica Arico

Dissertations

The profession of education traditionally embodies an idea of educating children on math, science, social studies, and English along with other elective course areas. In recent decades, however, the burnout rates and mental health of educators have become a subject of media attention and the basis for many new professional development programs. The one element wholly ignored in this space is the physiological wellbeing of educators and the impact physical health has on mental health and job satisfaction. This study set out to provide a baseline for beginning the discussion and future research on the physiological impact on educators and …

The Aesthetics Of News: Narrative Construction And Media Illiteracy In Contemporary India, Shashidhar Nanjundaiah

Dissertations

Amidst the public’s declining trust in news, media prosumers—that is, media consumers who have also become producers of mediated texts—are not equipped with any credible alternative mechanism to better understand the world around them. Prior academic studies of news and its delivery have not adequately explored the ideological framework we need to confront this frightening situation. This dissertation does so. I problematize the narration of news as an aesthetic process. Such mass-mediated narration stitches together our world in ideological ways. A tidal flow of stories highlights and obscures selected truths in a frenzy of “new” news cycles, the frequency of …

Dissertations

Scientific advancements have led to significant improvements in cancer treatment and increased survival rates. However, cancer survivors often experience long-term effects, including cognitive impairments known as cancer-related cognitive impairment (CRCI). CRCI is a common and distressing side effect that affects affected individuals’ quality of life. The discipline of speech-language pathology (SLP) is well-positioned to assess and treat CRCI. Still, there is a gap in determining the most effective support for cancer survivors with CRCI. This mixed methods, three-paper dissertation implements exploratory, cross-sectional survey design to examine how speech-language pathologists and survivors view CRCI symptoms, its impact on daily functioning, and …

Social Spaces, Places, And Substance Use In Shaping Queer Identities, Alessandra Milagros Early

Dissertations

Research has suggested that queer people may be more likely than their cisgender heterosexual counterparts to use substances. Largely, these higher rates are commonly explained through frameworks of victimization or (ab)use that render substance use as a form of coping or inherently problematic. While some queer people do use substances to cope, the social spaces, places, and contexts in which use often occurs are often obscured or ignored. More recently, contemporary queer criminologists have explored queer substance use and have considered how it is intimately linked to social space, place, identity formation, and community building. This dissertation draws from queer …
