Identifying Protective Factors Against Overweight And Obesity Within The Social Environment Of Women With Low Incomes., Monica M. Adams

Electronic Theses and Dissertations

Over two-thirds of the United States population have overweight or obese (OW/OB) weight statuses due in large part to an obesogenic environment that encourages unhealthful weight related behaviors. The obesogenic environment appears to place a larger burden on women with low incomes as they experience OW/OB disproportionately compared to other groups. Studies seeking to understand the impact of the obesogenic environment on this population have been deficit focused, largely examining environmental risk factors for OW/OB and ignoring protective factors against it. Most women with low incomes do not have an obese weight status and some women who have OW/OB statuses …

The Effects Of Self-Regulation Depletion And Race On The Willingness To Interact With Individuals With Mental Illness, Kenocha K. Epperson

Electronic Theses and Dissertations

Although the discrimination that Black individuals encounter is unique, it is similar in some ways to the discrimination experienced by individuals with mental illness (Corrigan & Wassel, 2008; Follmer & Jones, 2018; Jackson & Stewart, 2003). Research has found that these kinds of stigma can be overridden (Baumeister et al., 1998), but doing so requires self-regulation, which can be depleted (Gailliot et al., 2007). Because stigma exists against both Black individuals and those with mental illness, and because self-regulation is necessary to override those stigmas, the purpose of this project was to examine the relationships to which Black participants would …

Promoting Healthy Aging: An Investigation Of The Relationships Among Sport Satisfaction, Sport Identity, And Sport Commitment In The Well-Being Of Older Adults., Seonghun Lee

Electronic Theses and Dissertations

People are living longer and the aging population in the U.S. is showing significant growth, but it does mean they are necessarily living healthier lives. Public health representatives recommended people who want to live a healthy lifestyle as they get older need to regularly participate in sport and physical activity earlier in their life because it improves health and psychological and social well-being. However, approximately 80 percent of U.S. adults/older adults are insufficiently active; they participate for fewer than 150 minutes in moderate-intensity physical activity per week. To promote sport engagement, older adult sport and fitness service providers need a …

Development Of In Vitro Models To Study The Rapid Extraintestinal Dissemination Of Salmonella., Adarsh Gopinath

Electronic Theses and Dissertations

Salmonella appears in the bloodstream of mice in as little as 15 minutes after oral inoculation and establishes persistent colonies in the spleen and liver. While its pathway to blood is undetermined, this phenomenon is dependent on the activity of Salmonella pathogenicity island 2 (SPI-2) coded type III secretion system (T3SS) and CD18+ phagocytes. We hypothesize that dendritic cells associated with the basal face of the gut epithelium, that are naturally migratory and known to sample for luminal antigens directly transport Salmonella to the bloodstream. This process comprises of at least two phases, dissociation and reverse transmigration. We define dissociation …

The Emerging Oral Pathogen, Filifactor Alocis, Disrupts Neutrophil Functions To Enhance Survival And Dysregulate Inflammation., Irina Miralda Molina

Electronic Theses and Dissertations

Periodontitis is an irreversible, chronic inflammatory disease where pathogenic microbial communities accumulate in the gingival crevice. Advances in culture-independent techniques have facilitated the identification of new bacterial species in periodontal lesions, such as the Gram-positive anaerobe, Filifactor alocis. Neutrophils are a major component of the innate host response, and the outcome of their interaction with F. alocis may be a determinant of oral health status. While neutrophil functions typically protect the host against periodontal disease, oral pathogens have adapted to evade or disarm neutrophil microbicidal functions while promoting mechanisms that drive inflammation, which also provides a source of nutrients …

Aboveground-Belowground Interactions: Roles Of Soil Biotic And Abiotic Factors On Switchgrass's (Panicum Virgatum) Growth, Defense Against Herbivory And Cell Wall Chemistry., Binod Basyal

Electronic Theses and Dissertations

Plants constantly interact with their biotic and abiotic soil environments. Most terrestrial plants form beneficial associations with soil microbes such as arbuscular mycorrhizal (AM) fungi, which are widely known for their ability to transfer soil phosphorus and nitrogen to the host plants. They help plants tolerate drought stress and improve plant defense against herbivores such as plant-parasitic nematodes (PPNs). This dissertation investigates the role of AM fungi on switchgrass’s (Panicum virgatum) growth, cell wall chemistry, and defense against PPNs using a combination of growth chamber and field studies. Switchgrass is a native warm-season species which is gaining traction as candidate …

The Last Crusade: British Crusading Rhetoric During The Great War, Seth Walker

Electronic Theses and Dissertations

During the Great War many in British society started to utilize Crusading language and rhetoric to describe their experiences during the war. Those utilizing the rhetoric ranged from soldiers, journalists, politicians, to clergymen. The use of Crusading rhetoric tended to involve British nationalism, the region of Palestine, anti-Germanism, and more. Adding to the complexity, the soldiers’ and civilians’ rhetoric differed greatly between the two groups. While the soldiers focused on their personal experiences during the war, and often compared themselves to the British crusaders of old serving under Richard the Lionheart. The civilians had a less personal approach, and a …

A Baseline Measurement Of Alcohol Use And Its Relating Factors As It Pertains To Abilene Christian University, Emily Glaze
