Academic Performance And Educator Efficacy In Supporting Military-Connected Adolescents Among High Schools In A Georgia School District, Megan Louise Jones

Theses and Dissertations

The effects of a parent’s military service on their children are well-researched in the post-9/11 era, particularly for elementary-aged students. However, research involving adolescents is much narrower, despite 25% of all military dependents ranging between 9th and 12th grade. These students are already enduring major changes as adolescents, but military-connected adolescents are also navigating the many stressors of their family’s military affiliation. These students are oftentimes burdened by frequent moves, parental deployment, and acclimation to their circumstances. While the military family is acutely aware of the heightened stressors that potentially create chaos among the family unit, teachers’ awareness of these …

Spin Wave Devices For Embedded Applications And Information Processing, Raisa Fabiha

Theses and Dissertations

Device miniaturization is a prerequisite for modern day electronics. Spintronics offers immense potential in energy efficient data storage, solid states devices, ultrafast computing and other electronic applications because of their low power consumption, non-volatile nature and unique activation mechanism. The conventional nano-antennas used for wireless communication, biomedical and wearable devices and IoT applications are limited by the traditional Harrington limit. As we attempt to miniaturize the antenna size beyond its emitted wavelength (also called “subwavelength” antenna), its gain and efficiency plummet. To overcome this challenge, the researchers have proposed magnetoelectric antennas. The ultra-thin film based magnetoelastic antennas suffer from eddy …

The Role Of Sleep And Social-Ecological Supports In The Association Between Racial Discrimination And Cardiometabolic Risk In Black Youth, Jelaina R. Shipman-Lacewell

Theses and Dissertations

Black youth are at an increased risk for poor short and long-term cardiometabolic health, including obesity, hypertension, and type 2 diabetes. Racial discrimination and poor sleep are theorized as key factors contributing to cardiometabolic health. While adult studies support sleep as a pathway through which discrimination is associated with health, there is a critical gap in our knowledge of this pathway in youth. Socio-ecological supports may protect Black youth against stressors, including racism. However, studies of the protective nature of these factors in Black youth have primarily focused on psychological and behavioral outcomes. Thus, the current study built upon previous …

From Suicidal Ideation To Suicide Attempt: Clarifying The Role Of Painful And Provocative Events, Mallory Stephenson

Theses and Dissertations

The Interpersonal-Psychological Theory of Suicide hypothesizes that capability for suicide is acquired in part through exposure to physically painful and/or fear-inducing experiences, referred to as painful and provocative events (PPEs). Studies of PPE exposure offer an opportunity to characterize potential targets for suicide prevention and inform efforts to identify individuals at elevated suicide risk. However, the literature on PPE exposure and risk for suicidality has been limited by a reliance on cross-sectional designs, lack of genetically informed research, inclusion of risk-taking behaviors as potential PPEs, and focus on risk over resilience. In this dissertation, we aimed to address these knowledge …

The Influence Of Flavor On The Abuse Liability Of A Heated Tobacco Product And Its Feasibility As A Menthol Cigarette Substitute, Augustus White

Theses and Dissertations

Heated Tobacco Products (HTPs) purport to expose people that use cigarettes to fewer of the harmful or potentially harmful constituents of tobacco while still delivering reinforcing amounts of nicotine (Auer, Concha-Lozano et al., 2017). An exemplar of the HTP class, IQOS, and its three varieties of “HeatSticks” have been authorized by the Food and Drug Administration (FDA) as “Modified Risk Tobacco Products” (MRTP). However, as the FDA is planning to ban menthol as a characterizing flavor in cigarettes, questions remain regarding whether characterizing flavors should be permitted in HTPs (FDA, 2022e). New evidence regarding HTP abuse liability (i.e., the likelihood …

Interviews were conducted to investigate the similarities and differences among all participants …

The Sexually Dimorphic Role Of Connexin 43 In Bone Remodeling And Disuse-Induced Bone Loss, Gabriel A. Hoppock

Theses and Dissertations

Bone loss is frequently experienced by individuals undergoing long-term disuse, such as prolonged bedrest, immobilization due to paralysis or injury, and conditions such as spaceflight. Under normal physiological conditions, bone remodeling is balanced by bone-forming osteoblasts and bone-resorbing osteoclasts, and the activity of osteoblasts and osteoclasts is orchestrated by osteocytes. Osteocytes are the most abundant cell type found in bone and ample evidence suggests they are bone’s main mechanosensory cell type. Therefore, understanding osteocyte biology and responses to mechanical signals, or lack thereof during unloading, may lead to new therapeutic targets to combat bone loss during disuse. Previous data has …

Online Racism And Mental Health Symptomatology Among Black Adolescents: A Longitudinal Examination, Stephen M. Gibson

Theses and Dissertations

Online racism (i.e., racism perpetrated and embedded within media and platforms on the Internet) is increasingly becoming a public health concern. Recent empirical evidence demonstrates that over a three year period, Black adolescents reported experiencing at least one online racial discriminatory incident, including exposure to racist images or videos within digital spaces (Tynes et al., 2020). One way in which Black adolescents are exposed to online racism is through the consumption of digital news media on the coverage of racially traumatic events (e.g., murders of Black men and women by police officers, racial hate crimes committed against Black people) and …

Exploring The Relationship Of Intact Limb Knee Joint Loading With Step Lengths And Step Length Symmetry In Individuals With Lower Limb Amputation, Edward D. Syrett

Theses and Dissertations

Individuals with unilateral lower limb amputation (LLA) frequently experience intact limb knee pain, dysfunction, and osteoarthritis. These problems can worsen pre-existing reductions in mobility and quality of life that this population regularly experiences. It is widely accepted that knee joint loading is implicated in the development of knee joint issues, and intact limb knee joint load alterations are thought to be widespread in individuals with LLA. Prior work suggests that gait deviations frequently present in this population may be a contributory cause of these altered forces. These deviations can take many forms, but individuals with LLA commonly demonstrate alterations in …

Spatial Transcriptomics Unravels Palmitoylation And Zonation- Dependent Gene Regulation Of Aeg-1 In Mouse Liver, Alissa Saverino

Theses and Dissertations

Obesity-induced metabolic dysfunction-associated steatohepatitis (MASH) leads to hepatocellular carcinoma (HCC). Astrocyte-elevated gene-1/Metadherin (AEG-1/MTDH) plays a key role in promoting MASH and HCC. AEG-1 is palmitoylated at residue cysteine 75 (Cys75) and a knock-in mouse representing mutated Cys75 to serine (AEG-1-C75S) showed activation of MASH- and HCC-promoting gene signature when compared to wild-type littermates (AEG-1-WT). The liver consists of 3 zones, periportal, midlobular, and pericentral, and zone-specific dysregulated gene expression impairs metabolic homeostasis in the liver, contributing to MASH and HCC. Here, to elucidate how palmitoylation influences AEG-1-mediated gene regulation in regards to hepatic zonation, we performed spatial transcriptomics (ST) in …
