Psychological Mediation Of Minority Stress And Health: Exploration Of Risk Factors In Lgbq College Students, Kyndal Grammer

Electronic Theses and Dissertations

Decades of research have documented pervasive physical and mental health disparities among individuals holding a marginalized identity, including those who identify as lesbian, gay, bisexual, or queer (LGBQ). Heterosexism in the forms of harassment, rejection, and discrimination likely increases minority stress, which is theorized to contribute to documented health disparities. One group that may be particularly vulnerable to effects of heterosexist discrimination, harassment, and rejection is LGBQ college students, especially those who identify as first-generation and were raised in rural environments. The current study aimed to evaluate relationships between LGBQ discrimination, depression, and physical health outcomes at the bivariate level, …

Heavy Is The Arm That Wears The Cgm: An Investigation Of A Social Support Group Of Emerging Adults At A Type 1 Diabetes Camp, Mackenzie Dawes

All Theses

Type 1 Diabetes (T1D) is a chronic illness that can be profoundly isolating. T1D often fosters a sense of 'otherness' that is difficult for those without T1D to understand, due to the persistent necessity to monitor blood sugar levels, administer insulin injections, and navigate the ever-present risk of severe health complications if the T1D is mismanaged. For many young adults with T1D, the sense of isolation is magnified amidst the numerous life transitions characteristic of emerging adulthood. Establishing a community of peers with T1D can help mitigate the negative mental and physical consequences. Through semi-structured interviews, this study examines these …

The Effect Of Workload On Trust Repair: Testing A New Model Of Trust Repair, Jada Lester

All Theses

Given the importance of trust in human-automation interaction, there has been intense activity in understanding trust repair (Esterwood & Robert, 2021). However, despite the numerous trust repair studies, there is no coherent understanding of when and why trust repair works. A recently proposed theoretical model identified two unique categories of trust repair (central and peripheral) and the factors that might affect their success (Pak & Rovira, 2023). The current study tested a specific hypothesis arising from the theoretical model: variations in workload will affect central trust repair efficacy, but peripheral trust repair will be unaffected by workload. Participants engaged in …

For this research, 97 participants (35 attending surgeons and fellows, 32 …

The Impacts Of Wind On Coastal Trees, Julian Halil

All Theses

Trees in hurricane-prone areas are exposed to severe winds and flooding. We studied the physiological and structural responses of forested wetland trees in relation to wind stress. We evaluated the windfirmness of two forested wetland tree species. Baldcypress was chosen because of high survival in post-hurricane studies. In contrast, laurel oak co-occurs with baldcypress yet resists hurricane-force winds poorly. In a static winching study, we quantified the critical turning moment (Mcrit) required to topple both species. Mcrit increased with trunk diameter at breast height (DBH) and crown size. Baldcypress and laurel oak demonstrated similar Mcrit, but regression models indicate baldcypress …

A Transdisicplinary, Survivor-Centered Approach For Creating A System Dynamics Model Of Closed-Buyer Sex Trafficking Networks, Kemonte Yow

All Theses

One of the largest drivers of sex trafficking operations is the demand for commercial sex. To date, research from a quantitative side typically focuses on understanding how to best identify and remove victims from their trafficking situation and then support their healing and recovery. This may be because this is where data exists (in limited forms) to support quantitative modeling. This thesis broadens that scope to understand how demand for commercial sex impacts trafficking operations. In particular, this research implemented a transdisciplinary, survivor-centered approach to build a system dynamics model of a closed-buyer sex trafficking network, which is a network …

Children Of The Grave: The Rise, Fall, And Experience Of Heavy Metal Music During The Latter Cold War From 1969-1991, Shelby Sibert

Photobiomodulation Of Bovine Oocytes During Maturation Increases Atp Content And Enhances Subsequent Embryonic Development, Kendall Richey

All Theses

Bovine in-vitro production(IVP) of embryos is a growing field for producing offspring with desirable genetics in the cattle industries. While IVP is effective, oocyte cytoplasmic maturation is compromised, and bovine oocytes matured in-vitro have reduced metabolic activity than those matured in-vivo. Mitochondria are the central unit of oocyte metabolism, producing ATP through OXPHOS. Photobiomodulation is a light treatment reported to improve metabolic activity. In five experiments, we measured the effects of photobiomodulation treatment with red LED at 16-(L-16) and 20 h(L-20) of bovine oocyte in-vitro maturation on subsequent embryonic development, mitochondrial activity and nuclear progression. Bovine COCs were aspirated …

Domination In Graphs And The Removal Of A Matching, Geoffrey Boyer

All Theses

We consider how the domination number of an undirected graph changes on the removal of a maximal matching. It is straightforward that there are graphs where no matching removal increases the domination number, and where some matching removal doubles the domination number. We show that in a nontrivial tree there is always a matching removal that increases the domination number; and if a graph has domination number at least $2$ there is always a maximal matching removal that does not double the domination number. We show that these results are sharp and discuss related questions.
