Effects Of Increased Temperatures And Migratory Status On Passerine Chick Rearing Phenology And Caterpillar Prey Synchrony, Marissa Calvert

College of Graduate Studies: Theses & Dissertations

Many species across the globe have been observed to shift the seasonal timing of life history events in response to climate change-induced shifts in their local environments. However, individual species vary greatly in the direction and magnitude of these phenological shifts. Variation in phenological responsiveness to climate change among interacting species can lead to phenological asynchrony, with potential consequences for survival and population health. In years with increased spring temperatures, the timing of passerine chick rearing and of caterpillar activity may shift earlier or later in the year. Differences in the magnitude and/or direction of phenological shifts among passerines and …

G.W. Carver School, built in 1939 and funded by automaker Henry Ford, is mentioned briefly in multiple works that either relate to Ford or cover the general history of Richmond Hill. Utilizing oral history and archival documents, this study emphasizes the significant contribution the SLAGS program made to students at G. …

Unmasked, Unbroken, And Transgressional: A Womanist Approach To Black Female Educators' Experiences With Intersectionality And Their Quest To Teach For Educational Liberation, Ty-Ria S. Jenkins

College of Graduate Studies: Theses & Dissertations

This qualitative study examines the experiences of six Black female educators committed to educational liberation, using Baszile’s (2006) Black Self and Beauboeuf-Lafontant’s (2008) politicized mothering as frameworks. Grounded in Black feminist thought (Hill Collins, 2000) and womanist pedagogy (Walker,1983), it explores how these educators navigate race, gender, and systemic barriers in education. Through qualitative interviews and sista circles (Johnson, 2015), participants shared their journeys of self-realization, political clarity, and transgressional teaching practices.

Findings reveal that Black female educators embody three layers of the Black Self—emergence, absence “invisibility” and self-awareness—while also engaging in politicized mothering through maternal care, political clarity, and …

Impact Of Y-Mixer Geometry And Flow Rate Modulation On Chemical Gradient Generators In Microfluidic Devices, Elizabeth Thurston Hutton

College of Graduate Studies: Theses & Dissertations

Various microfluidic structures are devised to generate tunable, stable spatiotemporal chemical gradients for single-cell studies. This work addresses the role of Y-mixer junctions in generating nonlinear gradients by increasing the width of one arm (bias), which is suspected to cause premature diffusion within the mixer. This study introduced a cinching feature to narrow the wider arm locally and redefine the junctions of these biased Y-mixers using four novel geometries defined by a 5-micrometer drawing rule. Furthermore, three flow rate factors allowed us to explore the impact on the generated gradient landscapes. The results showed that the four novel designs similarly …

Synthesis Of Tu100 Analogs And Biological Assays, Feyisope Tonye Oladapo

College of Graduate Studies: Theses & Dissertations

TU100 (14-methyl-5H-5,12-epiminobenzo[4,5]cyclohepta[1,2-b]naphthalene-6,11,13(12H)-trione) exhibits exceptional chemotherapeutic properties. It operates via a distinct mechanism that triggers cell death to create cytotoxic effects while concurrently inhibiting topoisomerase I and II. Its efficacy rivals that of well-known chemotherapeutic drugs like Daunorubicin. The distinctive characteristics of TU100 have led to initiatives aimed at creating structurally similar compounds to discover even more effective bioactive alternatives.

The analog synthesis incorporated quinoxaline or its derivatives (diphenyl quinoxaline, dipyridinyl quinoxaline, and dibenzophenazine-10,13-dione) that have been shown to have promising chemotherapeutic effects. Synthesizing the hetero naphthoquinones required a multi-step synthetic process, so quinoxaline/ derivatives intermediates are first prepared, then the …

Quantifying Inositol Phosphate Dephosphorylation To Understand The Role Of Recalcitrant Organic Phosphorus Forms On Harmful Algal Blooms In Freshwater Systems, Iffat Tasnim

College of Graduate Studies: Theses & Dissertations

Organophosphorus such as phytic acid, a surrogate species of inositol phosphate (IP), may serve as a source for orthophosphate (OP) in freshwater. In absence of OP, competent aquatic microorganisms upregulate the production of specialized enzymes to obtain growth-sustaining OP from organic phosphorus (org-P) forms. The contribution of recalcitrant org-P to the OP pool has been overlooked due to the lack of capable tools to measure OP production from org-P accurately. The objective of this study was to quantify OP production from phytic acid (a surrogate form of recalcitrant org-P) to assess the contribution of recalcitrant org-P forms to the total …

The Relationship Between Nutrition Knowledge And Dietary Behavior Of Student-Athletes, Kerry A. Smith, Kathleen Fritch, James Rost, Amy Jo Riggs, Juliann Sergi Mcbrayer, Monika Krah

Georgia Educational Researcher

The purpose of this study was to examine the relationship between nutrition knowledge and dietary behavior while controlling for academic major, year, and gender among Division III student-athletes. Sufficient nutrition is essential for athletic performance, injury reduction, and overall health. However, student-athletes face unique challenges that can disrupt optimal nutrition, including poor nutrition knowledge and access to available resources. While several studies have examined the relationship between nutrition knowledge and dietary behavior, no known studies have addressed this among Division III student-athletes. This non-experimental correlational study examined dietary behavior using the Rapid Eating and Activity Assessment for Participants (REAP-S) and …

Are Blow Flies (Diptera: Calliphoridae) Active Nocturnally In South Georgia?, Breana R. Manning

Honors College Theses

Medicolegal forensic entomology uses insect colonization of remains to estimate minimum post-mortem intervals (mPMI). Blow flies (Diptera: Calliphoridae) are among the earliest colonizers, yet their nocturnal activity remains poorly understood. This study aimed to determine whether blow flies are active at night and whether artificial light influences their behavior. Using baited bottle traps in both artificially lit and unlit environments near Georgia Southern University, flies were collected over two trials in fall 2024. Of the 1,843 blow flies collected, only six were captured at night (0.003%), suggesting minimal nocturnal activity. Lucilia coeruleiviridis preferred unlit environments. In contrast, Cochliomyia macellaria was …

The Role Of Horizontal Gene Transfer In Antibiotic Resistance Amidst Prevalent Community And Healthcare-Associated Mrsa Rates, Gabrielle Nascimento

Honors College Theses

In recent decades, cases of community-acquired MRSA (CA-MRSA) and healthcare-associated MRSA (HA-MRSA) have been on the rise. The ability of antibiotic resistance to transfer between microorganisms greatly expands its threat to the effective treatment and containment of bacterial infections. The mecA gene is found on a mobile cassette within the Staphylococcal cell and encodes for PBP2a, an alternate version of penicillin-binding protein (PBP) with less binding affinity for β-lactam antibiotics, increasing resistance to the effects of antibiotics. The goal of this research is to investigate the horizontal transfer of the mecA gene between various Staphylococcus species as well as to …

Epigenetic Potential Remains Stable Over 100 Years After Introduction, Danielle Dawkins

College of Graduate Studies: Theses & Dissertations

Introduced species provide important insights into organismal behavioral responses. Epigenetic mechanisms are one of the various ways in which behaviors can be modified, particularly through DNA methylation. Through such mechanisms, phenotypic changes can occur in response to environmental changes, allowing an organism to be more plastic. Epigenetic potential (EP) represents the capacity for an organism to be epigenetically modified, and can be measured by counting CpG motifs; cytosine adjacent to guanine within a DNA sequence. Phenotypic plasticity as it relates to EP has been studied extensively in the house sparrow (Passer domesticus), a globally introduced songbird. It is …
