Intergenerational Factors That Contribute To Millennial Church Engagement, Parker Sanderson

Electronic Theses and Dissertations

Millennial church attendance has declined since the beginning of the new millennium. Intergenerational ambivalence has been known to contribute to this phenomenon. Through this action research, the researcher sought to determine what intergenerational factors have led to millennials’ continued or discontinued attendance within churches. A phenomenological qualitative approach centered around interviews for this study was used to determine these intergenerational factors. The sample was taken from a 1,100-member church in a major Texas metropolitan area. The goal was to help church leaders decrease relational distancing and reduce ambivalent factors to increase millennial engagement in this local congregation.

Effect Of Macrophage Expressed Α7 Nicotinic Acetylcholine Receptor (Α7nachr) On Migration Of Macrophages During Inflammation, Kasey Keever

Electronic Theses and Dissertations

Sepsis is a life-threatening condition characterized by overwhelming inflammation, resulting in organ system damage, leading to a high mortality rate. Care in the clinical setting is supportive, and there are no approved sepsis-specific treatments. In septic mice, activation of the cholinergic anti-inflammatory pathway decreases cytokine secretion by leukocytes and improves survival. The cholinergic anti-inflammatory pathway is a reflex of the parasympathetic nervous system, converging on the α7 nicotinic acetylcholine (α7nAChR) at the surface of macrophages. Signaling through the receptor blocks NF-kB activation, thus cytokine secretion. Receptor activation has other effects on macrophages, including modulating their migration to …

In order to answer this overarching question, the researcher focused her study on two areas: first, what were the possible push factors that influenced parents to remove their children from public schools, and secondly, what were the pull factors that lead parents to choose learning pods over other school choice options. Through the data collected …

A History Of Complex Simple Lie Algebras, Avrila Frazier

Electronic Theses and Dissertations

In 1869, prompted by his work in differential equations, Sophus Lie wondered about categorizing what he called “closed systems of commutative transformations,” while around the same time, Wilhelm Killing’s work on non-Euclidean geometry encountered related topics. As mathematicians recognized this as a division of abstract algebra, the area became known as “continuous transformation groups," but we now refer to them as Lie groups.

Patterns and structures emerged from their work, such as describing Lie groups in connection with their associated Lie algebras, which can be categorized in many important ways. In this paper, we focus on Lie algebras over the …

Environmental Exposures And Aging., Daniel Chris Gomes

Electronic Theses and Dissertations

In recent years, research into air pollution has shown that exposure to certain components in air pollution, primarily PM2.5 can accelerate biological aging and thereby lead to increased susceptibility to multiple diseases. We hypothesize that prolonged exposure to air pollutants can result in premature aging leading to extensive tissue dysfunction and susceptibility to diseases. To examine this, we exposed mice to PM2.5 for 9, 15, and 21 days, then measured the telomere lengths, cellular senescence, and histone methylation patterns of multiple cell types. We found consistently increased telomere attrition, cellular senescence and advanced age-consistent histone methylation patterns in groups exposed …

Study Of The Effects Of Chronic Cadmium Exposure On The Pathogenesis Of Pulmonary Arterial Hypertension., Dakotah Dominique Cathey

Electronic Theses and Dissertations

We reported pulmonary artery hypertension (PAH) patients had elevated levels of Cd in both blood and urine, therefore, this study tested whether Cd directly induces PAH or facilitates PAH pathogenesis in mouse models. C57/6J mice were initially exposed to drinking water with or without 5ppm Cd for 8 weeks. Then, half the mice in both control and Cd groups were given SU5416 and hypoxia (SuHx) for 4 weeks to induce PAH, resulting in 4 subgroups: Control, Cd, PAH, and Cd+PAH. Diastolic and systolic functions of the left and right ventricles (LV, RV) were examined with echocardiography before and after PAH. …

Genetic Risk Scores For Hypertension And Chronic Kidney Disease In African Americans., Aastha Kakar

Electronic Theses and Dissertations

Hypertension (HT) and chronic kidney diseases (CKD) are complex conditions, disproportionally prevalent among African Americans (AA) and are influenced by multiple genetic as well as environmental factors. Genetic risk scores (GRS) enable the analysis of the combined effects of multiple single nucleotide polymorphisms (SNPs). This study investigates the association of blood pressure (BP) and CKD GRS with BP, hypertension (HT) and CKD; early-onset HT and CKD; and investigates interactions of the GRSs with environmental measures in AA. We observed a significant association between the BP-GRS with HT, SBP and DBP. The odds of HT for one standard deviation (s.d.) increase …

Formalizing The Faustian Bargain Within The Healthcare Domain: An End-Of-Life Approach., Rachel Appel

Electronic Theses and Dissertations

A Faustian Bargain refers to an individual making a “deal with the devil,” exchanging something moral or sacred for an unattainable earthly good. The Faustian Bargain has been used to describe a ubiquitous social dilemma inherent to human civilization: exchanging individual liberty for public goods (e.g., security) provided by societal leaders and governments (Ostrom, 1980). Research on Faustian Bargains often examines tradeoffs between outcome utility (i.e., value derived from the outcomes of a decision) and procedural utility (i.e., value derived from being involved in the decision process (e.g., Frey et al., 2004). Much of the research on Faustian Bargains has …

Automated Usability Evaluation Utilizing Log Files And Data Mining Techniques., Sima Shafaei

Electronic Theses and Dissertations

Usability evaluation is one of the essential aspects of software production.

Quantifying Impacts Of Climate Change On Headwater Streamflow Regime In Robinson Forest: Insights From 35-Years Of Data Collection., Lauren Brown

Electronic Theses and Dissertations

Climate change may shift patterns of streamflow permanence in headwater systems by altering the frequency, magnitude, duration, timing, and rate of change of surface streamflow, impacting both local ecosystems as well as regional water budgets and availability. While much uncertainty surrounds modeling-based methods to quantify the impacts of climate change on water budgets, long-term hydrologic data collected from headwaters in experimental research forests serve as critical evidence to reduce such uncertainty. The objective of this study is to quantify shifts in frequency, magnitude, duration, timing, and rate of change of streamflow in two headwater catchments with relatively little recent disturbance …

Genetically Engineering Gingipains For High Yield Large Scale Purification., Andrew E. Fuchs

Electronic Theses and Dissertations

Porphyromonas gingivalis is a keystone oral pathogen in the progression of periodontal disease and has been implicated in the etiology of many other systemic human diseases. P. gingivalis produces primary virulence factors termed the gingipains, a group of cysteine proteases. There is a high demand for high purity gingipains for downstream in vitro studies where P.g. is implicated, both oral and systemic. Gingipain production candidate mutant P.g. strains were generated to isolate each gingipain for large scale purification and the purified gingipains characterized. Two mutants were determined not to be viable for large scale purification of gingipains, each for different …

“I Became Myself”: Exploring Cultural Learning Through Stories And Storytelling., Leah Halliday-Johnson

Electronic Theses and Dissertations

Despite broad acknowledgement in education that culturally responsive teaching is essential to meeting learners’ needs, defining and operationalizing culturally responsive teaching remains a challenge. Along with being designed to meet the needs of students from diverse racial and cultural backgrounds who have traditionally been underserved, one commonly identified feature of culturally responsive teaching is building on students’ cultural assets to promote their learning. And while stories and storytelling are among the most common teaching tools, storytelling pedagogies tend to use stories to deliver content or to assess student learning. This dissertation explores collaborative story sharing as an approach to helping …

Investigating The Effects Of Subchronic Dietary Zinc Supplementation On Diet-Induced Metabolic Dysfunction-Associated Steatotic Liver Disease., Oluwanifemi Esther Bolatimi

Electronic Theses and Dissertations

Zinc deficiency is associated with metabolic dysfunction-associated steatotic liver disease (MASLD). Previous studies show zinc supplementation improves steatosis, but its therapeutic effects in established MASLD remain unclear. We developed a model to characterize the effects of zinc supplementation on high-fat diet (HFD) induced MASLD and hypothesized established MASLD would be attenuated. Mice were fed control diet or HFD for 12 weeks and then grouped into normal or zinc-supplemented diets for 8 additional weeks. At euthanasia, plasma and liver tissues were collected for phenotypic analysis. Twelve weeks of HFD altered glucose clearance and body composition. Eight weeks of subsequent zinc supplementation …

Environmental Exposures And Male Reproductive Outcomes., Damilola Rukayat Owoade

Electronic Theses and Dissertations

Male sexual dysfunction comprises various conditions, including erectile dysfunction (ED) and ejaculatory dysfunction. Testosterone deficiency (TD), which has been linked to some of these sexual dysfunctions, is characterized by low production of testosterone by the testes. These male reproductive outcomes may develop due to exposure to various risk factors, including environmental exposures. These environmental exposures may include volatile organic compounds (VOCs) and tear gas. This dissertation aims to examine the effects of tear gas exposure and VOCs on male reproductive outcomes. The association between tear gas exposure and male reproductive outcomes was assessed using data obtained from an online anonymous …
