Assessment Of The Utilization Of Healthcare Services Specific To Pregnancy-Related Complications In Rural And Medically Underserved Georgia, Diana L. Aguirre

College of Graduate Studies: Theses & Dissertations

Maternal mortality is a continuing issue, with rates for the state of Georgia (3.7 per 100,000 live births) are higher than that of the US rates (2.9 per 100,000 per live births) (Centers for Disease Control and Prevention, National Center for Health Statistics, n.d., 2023). However, maternal mortality may not account for health disparity factors, apart from access to quality care and physiological issues, which is a factor in pregnancy-related deaths, Pregnancy-related death, as defined by the US Centers for Disease and Control (CDC), is a death of a woman that occurs during or within one year of pregnancy that …

Submerged Aquatic Vegetation Response To Submarine Groundwater Discharge, Brielle K. Robbins

College of Graduate Studies: Theses & Dissertations

Ecosystem services provided by seagrass meadow communities in Florida Bay propagate economic opportunity and carbon sequestration among many other benefits. Recent seagrass die-off events have threatened Florida Bay’s ecosystem and its ability to provide these services. These impacts fuel ongoing research investigating the complex causes of seagrass die-offs. While previous research has described how water quality parameters can lead to seagrass die-offs, there is still much to be explored regarding the proximate causes for these water quality changes. The aquifers underneath the bay may hold the missing pieces in our understanding of die-off events, as submarine groundwater discharge (SGD) can …

The Effects Of Cucurbitacin B And Silmitasertib On Metastasis And Itga6 Using The Zebrafish Tumor-Xenograft, Alexandra Griffis

College of Graduate Studies: Theses & Dissertations

Ninety percent of cancer deaths are resultant from the metastasis of cancer cells. When cancer cells translocate through blood vessels or the lymphatic system, they may form tumors outside of their primary site. The processes of metastasis can begin quickly; after onset, metastasis is unforgiving, as it does not participate with the body’s physiological systems in an orderly way. In the past, our lab produced results indicating that a cell adhesion molecule, Integrin Alpha-6, may contribute to cancer cells' ability to metastasize. Integrins mediate interactions between the cell and the Extracellular Matrix (ECM), regulating cell attachment and cell migration. With …

Loggerhead Sea Turtle (Caretta Caretta) Nesting Experience, Seasonal Variation, And Hatching Success On A Georgia Barrier Island, Luke Sundquist

College of Graduate Studies: Theses & Dissertations

Loggerhead sea turtles nest commonly on the Georgia barrier islands and serve critical roles in human cultures, coastal economies, and multiple ecosystems. However, their global populations are declining and dependent on conservation efforts and informed management of natural and anthropogenic threats. Nesting offers a unique opportunity to research and protect this valuable marine species in terrestrial habitats. Microsatellite DNA sampling from eggshells can consistently identify nesting females from eggshells, allowing tracking of nesting behaviors for large populations over multiple years. Using this novel technology, we compared maternal investment and nest site-selection between first-time nesting neophytes and experienced remigrants. We sampled …

Middle Savannah River: An A/R/Tographic Ecopedagogical Ethnography Experimenting With Rhizomatic Perspectives, Lisa Augustine-Chizmar

College of Graduate Studies: Theses & Dissertations

This research is an experiment in perspective. Using the four commonplaces (Schwab, 1978), I practiced letting the Savannah River teach me what there is to know about the water, the land, the people, and the other entities that depend on ki through artistic, ethnographic, and ecopedagogical lenses. The ethnographic findings describe the social actors that depend on ki and give a voice to the River. The a/r/tographic findings display the River on a canvas map through two hundred years using paint, clay, photography, video, abstract acrylics, and fabric. Together, these methods contribute to a unique ecopedagogical journey. This word cloud …

The contents of blood can provide information about the physiological condition and health of vertebrates. This study seeks to better understand the stress physiology and blood bacteria presence of the sand tiger shark (Carcharias taurus), as sharks are known to have unique physiology and immune systems. In this study the blood metabolites glucose, lactate, and ketones (3-hydroxybuteric acid and acetoacetate), were used to understand how biotic and abiotic factors affect the acute stress response to capture and handling. Metabolite concentrations from blood plasma were analyzed using colorimetric assays. Glucose and ketones showed no significant responses to capture and …

For Black Girls, By Black Girls: Examining The Experiences Of Black Women In Historically White Learning Spaces And Reimagining Spaces With Our Needs In Mind, Florence Takeshia Brown

College of Graduate Studies: Theses & Dissertations

This study examined the experiences of Black women in historically white learning spaces and our needs in reimaged learning spaces developed for us. The conceptual framework for this study was Black Feminist Thought, critical geography, and Afrofuturism. Using sister circle methodology, participants discussed the simultaneous racialized and gendered experiences that Black women navigate in learning spaces and how technology and Afrofuturism could be beneficial in creating spaces for Black women. Despite our achievements in academic spaces, Black women experience microaggressive environments that have traumatic impacts on our psychological health and our overall experiences in learning environments. Our successes are acts …

The Relationship Between Age, Sport, And Years Coaching On Knowledge, Confidence, Preparedness, And Intention To Intervene With Youth Athletes Experiencing Mental Health Challenges, Allyson P. Looby

College of Graduate Studies: Theses & Dissertations

Introduction: Mental disorders can affect all ages and populations, but there is an increasingly high prevalence in the pediatric population. It is estimated that 1 in 5 youth between the ages of 9-17 experiences some degree of impairment from a diagnosable mental health disorder (Merikangas et al., 2010). Youth are often not equipped to seek professional support; making parents, teachers, and coaches key to detection and referral to professional help (Ng et al., 2021). The environment youth sports creates gives coaches the opportunity to have a greater impact on youth mental health (Das et al., 2016). Purpose: Determine if age, …

Investigating Salinity Intrusion Effects On Sapelo Island, Georgia Using Benthic Macroinvertebrate Bioindicators, Raymond Paul Kidder Ii

College of Graduate Studies: Theses & Dissertations

Coastal wetlands are threatened by the compounding effects of sea level rise and historical land modification. Historically, much of Sapelo Island, Georgia was deforested and drained using a series of ditches and canals to create arable land fit for agriculture and to provide drainage to the inhabited parts of the island. Today, this network of artificial channels is believed to be facilitating the movement of saltwater from the nearby estuary into freshwater areas on the interior of the island. This study aimed to better understand the frequency and magnitude of salinity intrusion events along with their resulting impacts to the …

Secondly, a …

Dna Methylation And The Response To Infection In Introduced House Sparrows, Melanie Gibson

College of Graduate Studies: Theses & Dissertations

Epigenetics is the study of molecular modification of a genome without changing its base pairs. The most studied type of epigenetic mechanism is DNA methylation, which is capable of turning a gene “on” or “off.” Epigenetic potential is the capacity to which an individual can have methylation on its genome. The more CpGs available, the greater the epigenetic potential. In invasive species, genetic variation has been observed to be paradoxical: not much of it exists on a genomic level, but epigenetically, phenotypic variation can occur. The focus on shift in gene expression in this study is on Toll-Like Receptor 4 …

Understanding The Feasibility Of Improving Interfacial Properties In Direct Ink Writing Of Silicone-Polyurethane Resin Hybrid Material, Ayobami Samuel Akinfenwa

College of Graduate Studies: Theses & Dissertations

The progress in materials engineering and the ability to make various models possible have made soft robotics a popular alternative to traditional robotics. Still, soft robots need various parts, like Printed Circuit Boards (PCBs), batteries, cables, fittings, and more, to work correctly or to get attached to other complex parts. These parts can have different material properties, like elastic moduli, strength, etc. Because of these differences, mechanical failures happen at the points where two materials meet, making soft robots less durable and less lasting in real-life situations due to failure. Conventionally, the fabrication of soft robot parts is through moulding. …

Nasal Accumulation And Metabolism Of Δ9-Tetrahydrocannabinol Following Aerosol (‘Vaping’) Administration In An Adolescent Rat Model, Alexa Torrens, Christina M Ruiz, Maricela X Martinez, Alex Mabou Tagne, Pritam Roy, Dakota Grimes, Faizy Ahmed, Valeria Lallai, Victoria Inshishian, Malia Bautista, Yen-Chu Chen, Marilyn A. Huestis, Aditi Das, Christie D Fowler, Stephen V Mahler, Daniele Piomelli

Institute of Emerging Health Professions Faculty Papers

Passive aerosol exposure to Δ9-tetrahydrocannabinol (THC) in laboratory animals results in faster onset of action and less extensive liver metabolism compared to most other administration routes and might thus provide an ecologically relevant model of human cannabis inhalation. Previous studies have, however, overlooked the possibility that rodents, as obligate nose breathers, may accumulate aerosolized THC in the nasal cavity, from where the drug might directly diffuse to the brain. To test this, we administered THC (ten 5-s puffs of 100 mg/mL of THC) to adolescent (31-day-old) Sprague-Dawley rats of both sexes. We used liquid chromatography/tandem mass spectrometry to quantify the …

Phonological Decoding Skill In Braille Readers: Implications For Dyslexia, Lindsay N. Harris, Luis E. Lopez, Ailing Li, Alecia Santuzzi

CISLL Publications

Highly developed phonological decoding ability is essential for leveraging the phonological decoding self-teaching loop to efficiently build a reading lexicon. In the present study we compared the phonological decoding abilities of blind braille-reading (n = 29) and sighted print-reading (n = 22) adults to investigate the possibility that braille’s complexity reduces instances of successful decoding and self-teaching. Such a disturbance of the learning loop would amplify any underlying cognitive deficits in braille readers and contribute to the high rates of learning disability diagnosis observed in blind children. Contrary to expectations, we found that braille readers had a higher …

Bypass Language En Route To Meaning At Your Peril, Lindsay N. Harris, Charles A. Perfetti, Elizabeth Hirshorn

CISLL Publications

The learning account of the puzzle of ideography cannot be dismissed as readily as Morin maintains, and is compatible with the standardization account. The reading difficulties of deaf and dyslexic individuals, who cannot easily form connections between written letter strings and spoken words, suggest limits to our ability to bypass speech and reliably access meaning directly from graphic symbols.

We split the HRS into two sections, the High-Transmission Beamline (HTBL) and the …

Cleaning The Variable Mess: A Population Genomics Approach To Understanding The Evolutionary History Of A Complicated Plant Group, Claire Marino

Honors Theses

The Solanum dioicum clade is a group of Australian bush tomatoes consisting primarily of species native to Western Australia and the Northern Territory whose species delimitations tend to be quite unclear. Since David Symon’s monograph A Revision of the Genus Solanum in Australia was published in 1981, little additional progress has been made in clarifying these relationships. In this project, a population genomics approach was used to analyze the relationships and delimitations between three species within the S. dioicum clade: Solanum dioicum, S. carduiforme, and S. ossicruentum. The use of population genomics methods is advantageous to understanding …

A Theoretical And Computational Model For Aquaponics Systems, Isabella M. Digiulio

Honors Theses

Aquaponics, a sustainable farming technique combining the principles of aquaculture and hydroponics, suffers from uncertainty in its optimal operating conditions, preventing large-scale adoption of this technology. Relying on experimentation or full-scale testing to address these uncertainties is an approach that is material, labor, time, and cost intensive. As a result, aquaponics would benefit from a complete computational model of the system. This would allow for information to be gained without long and expensive experiments, but rather with knowledge of system operations and a modeling software package. In this study, the Activated Sludge Model 1 (ASM1) matrix framework, traditionally used in …

Deposited Cigarette Smoke As A Driver Of Oxidation And Partitioning Processes On Indoor Surfaces, April Hurlock

Honors Theses

Despite the large amount of time that individuals spend indoors during their lives, very little attention was paid to the chemistry that occurs on indoor surfaces until recently. Although not visible to the naked eye, physical and chemical processes, such as partitioning and oxidation, are occurring on virtually every indoor surface in a typical household. Indoor pollutants, ranging from skin oils to environmental cigarette smoke, drive a lot of these processes. The transformation of indoor surfaces by indoor pollutants can increase chemical exposure risks as new irritants or carcinogens can be introduced to the surfaces. In this thesis, I describe …

Congress Is From Mars & Courts Are From Venus: Reconceptualizing Our Understanding Of Interbranch Relations, Lauren Hanson-Figueroa, Alexandra Piccirillo, Amy Steigerwalt

Emory Law Journal

In this Article, we argue for a reconceptualization of how to understand legislative-judicial relations in the United States. We propose that the Legislative and Judicial Branches of the U.S. government broadly reflect gender-stereotypical relations and divisions of labor in terms of both function and design. Congress was intended to be agentic and public, securely positioned as the public, lawmaking body; it fits the prototypical definition of Arendt’s “space of appearance.” The Legislative Branch can be conceptualized as men in a patriarchal culture, given agency and invited to action. In contrast, the courts reside in a more private sphere, toiling away …

The Effects Of Age On Working Memory Capacity And Neural Function, Jasmin P. Joshi

CMC Senior Theses

Do age-related differences in working memory capacities predict specific neural responses? Theories of working memory (WM) suggest that there are different types of WM processes that are associated with specific neural networks and WM declines with age. Event-related potentials (ERPs) evoked by certain tasks are also associated with specific cognitive functions. This study investigates whether specific types of working memory capacities are related to corresponding neural indices of attention and context updating (P3; visual oddball task) or semantic (N400; word-pair paradigm task) processes. In addition, it examines whether age affects this relationship. Younger adults (n=30; ages 18-23) and older adults …

Effect Of Aromatase Inhibitors On Bone Mineral Density In Black African Women With Breast Cancer, Dayib Said Buthul

Master of Medicine in Imaging and Diagnostic Radiology

Introduction: Aromatase inhibitors (AIs) are a commonly used type of endocrine therapy for post-menopausal women with breast cancer. In clinical trials with a predominant Caucasian population, it has been shown to cause reduction in bone mineral density of up to 1.5% and 3.2% in total hip and 2.6% and 4% in lumbar spine after 1 and 2 years of AI therapy respectively. Previous studies have shown that black women tend to have higher bone mineral density reserve compared to Caucasians. To the best of our knowledge no study has described the effect of AIs on bone mineral density in black …

Meta-Narrative Review Of Pd-L1 By Immunotherapy On Triple-Negative Breast Cancer, Hannah Lazo, Tyler Harris, Hao Truong, Alina Masroor

Research Methods Poster Session 2023

Triple-negative breast cancer (TNBC) is an aggressive form of subtype breast cancer and there are currently new treatments being discovered such as the combination of immunotherapy and chemotherapy. In immunotherapy against triple-negative breast cancer, checkpoint inhibitors like PD-1/PD-L1 treat TNBC by blocking the “off” signal that prevents T-cells from killing cancer cells. As a group, we conducted a meta-narrative review collecting results from primary sources such as clinical trials and human experimental studies to support our research question on how PD-L1 inhibitor treatments compare to other treatments in patients with TNBC. The review included articles searched from Embase, Pubmed, EMBASE, …
