The Taphonomy Of Teaching Skeletons, Emily T. Siddell

Honors College Theses

Human remains have been used in teaching contexts since the mid-1600’s and this practice still continues today. After human skeletal remains have been used in teaching contexts they are sometimes sold, repurposed, or improperly disposed of. This creates the potential for these remains to end up in forensic contexts and would need to be identified as being teaching specimens. The purpose of this research project is to understand the impacts of the methods that are used to clean and prepare skeletal teaching specimens, as well as the impacts of the subsequent use and curation of the human remains. The materials …

Portraits Of A Rural Georgia High School Stem Program, Jonathan L. Garner, Gwen Scott Ruttencutter, Forrest R. Parker Iii

Georgia Educational Researcher

This research examined school personnel’s strategies and practices responsible for increasing student science proficiency at a certified rural high school STEM program. In the United States, difficulties have developed in adequately preparing students for careers in STEM sectors, especially in secondary education. This trend has led to increased difficulties for high school graduates competing globally for high-paying jobs. Rural schools have been especially susceptible to inadequately preparing their students academically. I used qualitative research portraiture to generate a mental image of the STEM program at the selected high school. I interviewed three teachers and two administrators in a certified rural …

Enhancing Flight Delay Predictions Using Network Centrality Measures, Joseph Ajayi

College of Graduate Studies: Theses & Dissertations

Accurate prediction of flight delays remains a formidable challenge within the aviation industry, owing to its inherent complexity and the interconnectivity of its operations. Traditional flight prediction methods frequently utilize meteorological conditions—such as temperature, humidity, and dew point—alongside flight-specific data like departure and arrival times. However, these predictors often fall short of capturing the nuanced dynamics that lead to delays. This thesis introduces network centrality measures as novel predictors for enhancing the binary classification of flight arrival delays. Furthermore, it emphasizes the application of tree-based ensemble models, which are recognized for their superior ability to model complex relationships compared to …

Hybridization And Duplex Stability Of Peptide Nucleic Acid Containing An Azobenzene Switch, Carmen J. Velasquez

College of Graduate Studies: Theses & Dissertations

Light-driven molecular switches that can be turned on and off on demand have found many biological applications. For DNA, RNA, and synthetic derivatives, the switch can be used to interfere with a hybridization event with a complementary strand. To explore this potential, we have synthesized three light-sensitive PNA which have an azobenzene group (PNA-5azo5 and PNA-4azo4), and two azobenzene groups (PNA-2azo5azo2) as part of the PNA backbone. UV experiments were used to verify the conversion to the cis-isomer from the initial trans state for all of the single-stranded Azo-PNA ( PNA-5azo5, PNA-4azo4, and PNA-2azo5azo2) by irradiating at 365 nm …

The Relation Between Disordered Eating And Perceived Stress, Tori E. Byars

College of Graduate Studies: Theses & Dissertations

Disordered eating behavior encompasses a spectrum of maladaptive eating patterns, including emotional eating, binging, restricting, and other similar behaviors. Perceived stress is the extent that an individual perceives their demands exceed their ability to cope. Existing research has demonstrated a positive relation between high ratings of perceived stress and disordered eating behaviors (King et al., 2009; Skead et al., 2018). The current study aimed to expand this research by examining the relation between disordered eating and stress in students, workers, and those who partake in both commitments. Utilizing a single survey, participants completed assessments including the Perceived Stress Scale, the …

This study investigated the relationships among Attention-Deficit Hyperactivity Disorder (ADHD) symptoms and common comorbid struggles for clients, including Generalized Anxiety Disorder (GAD) symptoms, and executive functions, especially emotion regulation. ADHD and GAD are prevalent mental health conditions, are commonly comorbid with each other, and are both correlated with relative deficits in executive functions. Executive functions comprise higher-order cognitive processes like planning, inhibition, initiation, and monitoring, as well as emotion regulation. Prior research established connections among ADHD symptoms, GAD symptoms, and emotion regulation but did not examine which specific facets of emotion regulation were most relevant. The current study aimed to …

A Novel Magnetorheological Pump Concept For Insulin Delivery, Mohammad Towhidul Islam Rimon

College of Graduate Studies: Theses & Dissertations

Over the past 25 years, awareness of type 1 diabetes has significantly increased, leading to a comprehensive understanding of various aspects, including its genetics, epidemiology, and disease burden. According to the Type 1 Diabetic Index, about 8.7 million people around the world live with this long-term autoimmune disease characterized by insulin deficiency and resultant hyperglycemia. However, the increased availability and utilization of artificial pancreas systems could potentially save 673,000 lives by 2040. Although, the advancement of diabetes technology offers Type 1 diabetic patients more tools to enhance glycemic management and achieve effective outcomes, many patients are still hesitant to adopt …

Variation In The Fear Response Of Atlantic Sand Fiddler Crabs (Leptuca Pugilator) To Anthropogenic Disturbance, Katrina L. Buttram

College of Graduate Studies: Theses & Dissertations

Leptuca pugilator is a common inhabitant of southeast Georgia salt marshes. This study examined the boldness of Leptuca pugilator across environmental conditions and human impacts. Here, boldness was defined as time taken to reemerge from a burrow after a fear stimulus. I hypothesized that crabs would vary in their boldness based on their surroundings, reproductive timing, and sex. Field and experimental trials were conducted to isolate which factors most influence boldness. Field trials were conducted at four sites varying in human influence throughout the breeding season. During each survey, vegetation height, substrate temperature, average burrow width, burrow count, and distance …

Their Country: Black Women, Three Chords, And The Truth, Dmetri J. Smith

College of Graduate Studies: Theses & Dissertations

ABSTRACT

Country music has long overlooked and at times outright erased the contributions of people of African descent. The past and present contributions of Black women are particularly ignored. Country music— a racially contested space centered in Nashville, Tennessee— is imbued with themes referencing the “good ole days” that were dangerous times for anyone who was not White, male, cisgender, and heterosexual. The genre has only become slightly more welcoming to those who are not part of the dominant class. And yet, there are Black women who feel called to use country music as their storytelling medium. My research shows …

Understanding The Role Of Recalcitrant Organic Phosphorus Mineralization On Harmful Algal Blooms At The Sediment-Water Interface Of Freshwater System, Tasnuva Farnaz

College of Graduate Studies: Theses & Dissertations

Over the past few decades, an enormous number of resources have been allocated to reduce the amount of phosphorus (P) entering the environment from both point and non-point sources. Nevertheless, the decrease in external P loading has not always resulted in a simultaneous decrease in the occurrence of harmful algal blooms (HABs) in waters contaminated with phosphorus. A two-part study is currently being conducted to investigate and measure the role of legacy recalcitrant P forms in the overall pool of soluble reactive phosphorus (SRP). However, the objective of this particular study is to evaluate the potential of Organic Phosphorus (PO) …

Cultivation Of A Commercially Important Macroalga (Ulva Sp) For Polyculture Research In Coastal Georgia, Kyle Mundy

College of Graduate Studies: Theses & Dissertations

The Georgia coast has shown great potential for large-scale oyster aquaculture, and the rate at which the sector has grown demands implementation of novel techniques to ensure sustainability and success in the face of climate change. One practice – integrated multi-trophic aquaculture (IMTA) or polyculture – is known to have positive effects on the health and quality of farmed organisms and the surrounding environment through low pH/alkalinity amelioration, while also being a unique and viable way for a farming operation to diversify its products. To date, there has been no such attempt at investigating or demonstrating macroalgae culture in Georgia. …

Transcriptional Induction Of Immune Pathway Genes And Subsequent Antibacterial Activity In The Digestive Tract Of The Cat Flea (Ctenocephalides Felis)., Katie A. Weber

College of Graduate Studies: Theses & Dissertations

Fleas (Order Siphonaptera) are ectoparasites that serve as vectors of several human diseases (cat scratch disease, flea-borne spotted fever, murine typhus, and plague). Typically, these pathogens are acquired through the ingestion of a host-derived bloodmeal; thus, the lumen of the gut is the first barrier encountered by imbibed pathogens. During the early stages of infection, microbes come into contact with surrounding midgut epithelial cells which trigger a series of host responses to combat local infection. Specifically, pathogen recognition leads to intracellular signaling and an increase in the production of antimicrobial peptides (AMPs) via the IMD and Toll immune pathways. While …

Aggressive And Non-Aggressive Behaviors In Mixed And Non-Mixed Dorymyrmex Smithi And Dorymyrmex Bureni Colonies Of Southeastern Georgia, Usa, Renee K. Nowicki

College of Graduate Studies: Theses & Dissertations

Dorymyrmex species, ‘pyramid’ or ‘cone’ ants, are Dolichoderines distributed across North America. Two relatively well-studied species, Dorymyrmex smithi and Dorymyrmex bureni, are commonly found throughout southeastern Georgia. These species are part of a socially parasitic relationship while simultaneously having starkly different colony structures. Dorymyrmex smithi is a polydomous, polygynous species with colonies that are often expansive, at times having hundreds to thousands of nests per colony. Dorymyrmex smithi is a temporary social parasite of D. bureni, a monodomous, monogynous species. The specific mechanism of this parasitism is currently unknown. Preliminary behavioral assay data from a limited number of …

Understanding The Impact Of Process Interruption On Mechanical Properties In Metal Additive Manufacturing: A Comprehensive Investigation, Poojith C. Chigurupati

College of Graduate Studies: Theses & Dissertations

Metal additive manufacturing techniques enable rapid prototyping and on-demand manufacturing while improving supply chain resiliency. Changes in microstructure and micro-mechanical characteristics of 3D printed metal parts occur due to the influence of process interruptions on melting-solidification cycles during the layer evolution in additive manufacturing processes. The process interruption can deteriorate the structural integrity of the 3D printed parts and generate micro-flaws in the interruption region. Manufacturing post-processing techniques such as Heat-Treatment methods can enhance the mechanical properties of the parts. Since variations commonly happen at the layer level, the investigation of mechanical properties must be done such that these variations …

Testing Differential Predation As A Mechanism Of Color Polymorphism In A Cryptic Lizard., Justin A. Sanclemente

College of Graduate Studies: Theses & Dissertations

Selection via predation is a strong evolutionary force on small organisms, producing unique phenotypic adaptations. In cryptic species, different populations may exhibit color polymorphisms to better match multiple substrates or backgrounds. Here, I conducted a clay model study in the Ocala National Forest of Florida (USA) to test predation as a selective mechanism for color polymorphism in the Florida scrub lizard (Sceloporus woodi). Clay models were constructed to resemble light and dark morphs of S. woodi and placed on contrasting substrates in longleaf pine and Florida scrub stands. It is hypothesized Florida Scrub Jays (Aphelocoma coerulescens) …

Evaluating Reactive Gliosis In The Brain Of Adult Zebrafish Following The Ingestion Of Nanopolystyrene., Hannah A. Kelehear

College of Graduate Studies: Theses & Dissertations

Polystyrene nanoplastics are one of the most pervasive environmental contaminants and have been shown to infiltrate multiple organ systems following ingestion. Studies in several animal models and humans have demonstrated that nanoplastics can cross the blood-brain barrier. Additionally, there is evidence that plastics will induce an inflammatory response in the brain involving reactive gliosis of microglia and astrocytes. This process has yet to be thoroughly investigated in the zebrafish model system in the context of micro-/nanoplastic ingestion. In the current study, we examined microglial and astrocytic phenotypes in the adult zebrafish telencephalon after consuming food contaminated with 44 nm polystyrene …

Beyond The Strong Black Woman: Navigating Resilience And Mental Health Using Social Media For Culturally Tailored Resources, Muchaneta N.M. Chikawa

College of Graduate Studies: Theses & Dissertations

Society views the strength of Black women as commendable as it shows positive qualities such as resilience and perseverance. While these traits are characterized as positive, Black women’s survival in American society has heavily depended on their strength, resulting in mental health illnesses such as anxiety and depression. The idea that Black women must exude strength and fortitude through adversity is labeled the Strong Black Woman Schema (SBWS). The SBWS is a race-gender schema that prescribes culturally-specific feminine expectations for Black women.

There are limited culturally-tailored resources for Black women to address mental health at collegiate institutions. As a result …

Analyzing Prominent Genes In Acute Lymphocytic Leukemia (All), Shima Z. Omar

Honors College Theses

Acute lymphocytic leukemia (ALL) is the most common type of childhood cancer. Leukemia is a type of cancer that involves the bone marrow and blood. This research study examined prominent genes in the disease. Two groups of genes, tumor suppressor and cell differentiation, were compared using statistical analysis to compare their binding potential and epigenetic potential. It is most likely that I failed to detect significant differences either because these genes’ function in the disease etiology is not strongly contexed to changes in expression, or that the magnitude of the differences were too slight to be detected with these methods. …

Contemplation Of Improvement Efforts To Manage Combined Sewer Overflows †, Younghan Edwin Jung, Myung Jeong, Hwandon Jun, Trevor Smith

Civil Engineering & Construction: Faculty Publications

Combined sewer overflow (CSO) is a significant environmental concern and public health risk (e.g., water contamination, eutrophication, and beach closure). The Environmental Protection Agency (EPA) has introduced the National Pollutant Discharge Elimination System (NPDES) permitting program to regulate and address this matter. This program mandates the control of CSOs for more than 700 municipalities obligated to devise Long-term Control Plans (LTCPs) to curb combined sewer overflows and reduce them to safe levels. The LTCP involves diverse strategies, including sewer separation, green infrastructure improvements, and conventional gray infrastructure upgrades. This study investigates several municipalities’ solutions for CSO problems that use conventional …
