The Experiences Of Military Parents Homeschooling Using Online Teaching Resources, Georgia George Watters
Walden Dissertations and Doctoral Studies
U.S. military members and their families relocate from one duty station to another on average once every 3 years. Children in military families change schools often, introducing potential problems such as struggling to make new friends, having trouble adjusting to new teaching styles, and losing academic credits due to the transition from one school to the next. Homeschooling that incorporates online resources can provide instructional continuity, social interaction opportunities, and submission of required periodic assessments. The primary purpose of this phenomenological study was to examine the experiences of military parents involved in homeschooling their children using online resources. The research …

Government Senior Executives' Perceptions Of Brain Drain On Leadership In The United States Virgin Islands, Shurla Jeffers-Knight
Walden Dissertations and Doctoral Studies
Highly qualified individuals are leaving the Caribbean and relocating to the United States and other developed countries. Researchers describe this resulting flight of human capital, or brain drain, from the Caribbean as a problem which has no clear definition or immediate solution. This phenomenological study explored perceptions of government senior executives in the United States Virgin Islands (USVI) of the cause and impact of brain drain. Burns' and Bass's transformational and transactional leadership theories were used as the framework for this study. Data were collected through a demographic questionnaire and semistructured interviews with a snowball sample of 10 participants. Data …
Beyond Elections: Ghana's Democracy From The Perspective Of The Citizenry, Ransford Osafo-Danso
Beyond Elections: Ghana's Democracy From The Perspective Of The Citizenry, Ransford Osafo-Danso
Walden Dissertations and Doctoral Studies
Ghana's democracy has been hailed by scholars, practitioners, and the international community in recent years as a shining example in the West African subregion as a result of the country's record of organizing successive elections with minimal or no violence. However, the evaluation of Ghana's democracy has predominantly focused on the elections and disproportionately captures the views of the political elite; conspicuously missing is the perspective of the ordinary Ghanaian. This presents an incomplete picture of Ghana's democracy, given the relevance of citizens' participation in democratic societies. To address this gap in knowledge, this qualitative case study explored the practice …

The Regulation Of Vitamin A Metabolism, Mark Adams
The Regulation Of Vitamin A Metabolism, Mark Adams
All ETDs from UAB
Bioactive vitamin A takes form as several molecules, among them all-trans-retinoic acid (RA) is the major form and influences a wide range of biological processes. RA must be synthesized through a two-step mechanism, where all-trans-retinol is first oxidized to all-trans-retinaldehyde by retinol dehydrogenases (RDHs) and retinaldehyde is further oxidized to RA by retinaldehyde dehydrogenases (RALDHs). The first step, retinol to retinaldehyde conversion is the rate limiting step and therefore a likely target of mechanisms that modulate RA synthesis. Despite this, many of the enzymes that are involved in retinol and retinaldehyde interconversion have yet to be identified and thus many …

Competition From New Neurons Drives Circuit Refinement In The Adult Dentate Gyrus, Elena W. Adlaf
All ETDs from UAB
The hippocampus encodes sensory information into memories. The dentate gyrus (DG) region is viewed as the entry point into the hippocampus, receiving sensory and spatial signals from perforant path axons of the entorhinal cortex (EC). Ever since researchers discovered a neurogenic niche in the subgranular zone (SGZ) of the DG in adult animals and humans, many studies have been aimed at discovering how these continually proliferating granule cells (GCs) contribute to the network. Immature GCs have dendrites that project densely into the molecular layer alongside mature GCs and there is morphological evidence that immature excitatory spines preferentially synapse onto existing …
Pathophysiology And Metabolic Dysfunction Following Polytrauma, Robert Mackay Akscyn
Pathophysiology And Metabolic Dysfunction Following Polytrauma, Robert Mackay Akscyn
All ETDs from UAB
Polytrauma, a combination of injuries to more than one body part or organ system, is common in modern warfare and in automobile and industrial accidents. The combination of injuries can include burn, fracture, hemorrhage, trauma to the extremities, and trauma to specific organ systems. These injuries are highly survivable when occurring singly. However, when they occur in combination the prognosis is worsened. To investigate the effects of combined injuries, we have developed a new and highly reproducible model of polytrauma. This model combines burn injury with soft tissue and gastrointestinal (GI) tract trauma. Male Sprague Dawley rats were subjected to …

Subsurface Parameter Estimation In Oilfield Modeling, Fatin Alawam
All ETDs from UAB
Inverse problems involving partial differential equations have many physical applica- tions. One of the most important applications is in petroleum reservoir modeling. The estimation of petroleum reservoir properties is an essential component in predicting reservoir behavior. Generally, oil and water are present together in petroleum reservoirs and the resulting reservoir model consists of two nonlinear partial differential equations. Much research deals with two phase flow in porous media assuming incompressibility, but a few researchers consider the weakly compressible case which generally applies when the reservoir model does not include a gas phase. In this thesis we assume the weakly compressible …

Regulation Of The Regulatory T Cell-Immunoglobulin A Pathway, Katie Lynn Alexander
All ETDs from UAB
A dysregulated immune response to the microbiota is a defined characteristic of Crohn's Disease (CD), a type of Inflammatory Bowel Disease (IBD). Understanding how homeo-stasis is maintained in the intestine despite the immense concentration of bacteria present is an active area of research. Regulatory T cells (Tregs) play an important role in mucosal tolerance by controlling inflammation and modulating immune responses initiated by T effector cells (Teffs). Tregs also provide vital survival factors to IgA+ B cells in the intes-tine in order to support Immunoglobulin A (IgA) responses as part of a protective Treg-IgA pathway, which functions to maintain mutualism …

Freshwater ecosystems play a central role in the environment. Through various processes such as nutrient recycling, groundwater recharging, and the attenuation of many pollutants these biological systems help to maintain environmental health. Unfortunately, many recent studies have identified emerging threats to these special environments and the life they sustain. One source of mounting concern is a group of compounds that interact with the endocrine systems of humans and wildlife. Known as endocrine disrupting chemicals (EDCs), these natural and synthetic chemicals may mimic or interfere with the action of natural hormones—thus disrupting the endocrine system. Multiple studies have reported negative effects …

Global Measures Of Gender Empowerment: A Case Study Of Sri Lankan Export Processing Zone (Epz) Workers, Peter Hancock, Sharon Middleton
Research outputs 2014 to 2021
This pape r focuses on global measures of gender empowerment released a n- nually by the UNDP and the World Economic Forum. It discusses and critiques these measures on a global level and juxtaposes this analysis against research conducted among women who work in Sri Lanka's Export Processing Zones (EPZs). Global measures of gender equality show that in Sri Lanka gender-based inequality is increasing, despite the nation dramatically improving its economy and poverty levels and meeting some of the Millennium Development Goals. To explain this contradiction, we sampled 2,304 women to explore how they experienced gender and empowerment and to …

Mechanisms Contributing To Differential Regulation Of Pax3 Downstream Target Genes In Normal Human Epidermal Melanocytes Versus Melanoma Cells, Danielle Bartlett, Glen M. Boyle, Mel Ziman, Sandra Medic
Research outputs 2014 to 2021
Melanoma is a highly aggressive and drug resistant form of skin cancer. It arises from melanocytes, the pigment producing cells of the skin. The formation of these melanocytes is driven by the transcription factor PAX3 early during embryonic development. As a result of alternative splicing, the PAX3 gene gives rise to eight different transcripts which encode isoforms that have different structures and activate different downstream target genes involved in pathways of cell proliferation, migration, differentiation and survival. Furthermore, posttranslational modifications have also been shown to alter the functions of PAX3.We previously identified PAX3 downstream target genes in melanocytes and melanoma …

The maintenance of glucose homeostasis within the body is crucial for constant and precise performance of energy balance and is sustained by a number of peripheral organs. Estrogens are known to play a role in the maintenance of glucose homeostasis. Aromatase knockout (ArKO) mice are estrogen-deficient and display symptoms of dysregulated glucose metabolism. We aim to investigate the effects of estrogen ablation and exogenous estrogen administration on glucose homeostasis regulation. Six month-old female wildtype, ArKO, and 17β-estradiol (E2) treated ArKO mice were subjected to whole body tolerance tests, serum examination of estrogen, glucose and insulin, ex-vivo muscle glucose uptake, and …
