Florida Sand Skink And Blue-Tailed Mole Skink: Expanding Geographic Coverage Of Genetic Analysis For Conservation, Emma Simpson

College of Graduate Studies: Theses & Dissertations

The Lake Wales Ridge is important scrub habitat that has been increasingly altered since the post-Columbian settlement in Florida. This loss of habitat has caused extreme anthropogenic fragmentation within the Lake Wales Ridge resulting in isolation among extant scrub patches. To expand the geographic scope of previous studies and answer questions concerning population connectivity, we characterized genetic diversity and differentiation using cytochrome-b and microsatellite genetic markers for two endemic skink species: the Florida Sand Skink (Plestiodon reynoldsi) and Blue-tailed Mole Skink (Plestiodon egregius lividus). Both species display historical isolation between central and southern Lake Wales Ridge …

Does Insufficient Effort Responding Account For The Relationship Between Psychopathy And Social Desirability?, Logan F. Folger

College of Graduate Studies: Theses & Dissertations

This research investigated the relationship between self-report psychopathy and social desirability and whether insufficient effort responding may impact this relationship. It was hypothesized that insufficient effort responding is biasing the relationship. Therefore, the significant negative relationship between psychopathy and social desirability may approach zero after isolating insufficient effort responding data. Two studies were conducted to aid this investigation. The first study utilized the Monte Carlo method to simulate this relationship. The simulation had 1,000 trials using 1,000 participants with proportions of valid respondents ranging from 0.0 to 1.0 with increments of 0.1. The results showed that insufficient effort responding may …

The Perspective Of Riverkeepers And Environmental Groups On Poor Water Quality In Georgia, Jacob A. Crawford

Riverkeepers and environmental groups currently face the complex task of defending watersheds. In Georgia, these efforts are complicated by the vast geographical and racial diversity within the state. This study examined the riverkeepers and environmental groups need to improve advocacy abilities to defend communities they serve from poor water quality, what communities in Georgia are being impacted by poor water quality, what disconnects exist between riverkeepers, environmental groups, and governmental agencies, and how COVID-19 has challenged the riverkeepers and environmental groups. Using qualitative interviews with eleven riverkeepers and environmentalists, the findings suggest that collaboration with riverkeepers, enforcement of current policy, …

Ring Bose–Einstein Condensate Atomtronic Rotation Sensor, Oluwatobi I. Adeniji

College of Graduate Studies: Theses & Dissertations

We propose a design for an atomtronic rotation sensor consisting of an array of Bose– Einstein condensates (BECs) confined in a double–target–array potential. The purpose of the sensor is to measure the rotation speed, Ω_R, of the sensor’s rest frame with respect to the “fixed stars.” The atomtronic system consists of an ultracold gas of sodium atoms compressed, using laser light, into a thin horizontal sheet and subjected to a double–target– array potential within the horizontal plane. A “target” BEC consists of a disk–shaped condensate surrounded by a concentric ring–shaped condensate. A “double–target” BEC is two adjacent target …

Femininity Reclaiming Chivalry In The Harry Potter Series, Ashley M. Watson

College of Graduate Studies: Theses & Dissertations

This paper focuses on the reclaiming of chivalric values by female characters in the Harry Potter series by comparing them to Arthurian characters. Scholars have extensively compared the narrative of the Knights of the Round Table to the global phenomenon of the Harry Potter series, but in this paper I explore, through a feminist lens, a character comparison of the Harry Potter novels and Sir Thomas Malory’s Le Morte D’Arthur. I will show how female characters in modern literature reclaim chivalry. This is important because it exemplifies a shift in the position of women into a more active role. I …

Perplexions: Perceptions, Plexi And Prose, Amy B. Nelson

College of Graduate Studies: Theses & Dissertations

An understanding of our world is unique to each individual and their experiences. While experiences are often shared, we all process them according to our own schema. Through exploration into the multiple facets of plexiglass, my work examines trauma, loss and its lasting effect on a person's memory of the past, present and perception of the future. These experiences can cause an abrupt shift in personal schema and reshape one’s perception of the world. Through the combination of visual and linguistic stimuli, my trauma-informed work can be a catalyst for my viewers to discuss what they are experiencing and why. …

Generalization Of Net Benefit Of Diagnostic Tests Into Multi-Stage Clinical Conditions: A Collapsing Approach, Ferdous Ahmed

College of Graduate Studies: Theses & Dissertations

Evaluating diagnostic tests based on benefit-risk involves both the tests’ accuracy and the clinical implications of the diagnostic errors. Diagnostic tests are commonly classified into two stages: either positive or negative for a clinical condition (diseased or non-diseased). However, some diseases have more than two stages, such as Alzheimer’s. In diseases with more than two stages, the benefits and risks of the clinical consequences could differ from stage to stage. I could not find any investigations to account for the difference in benefits and risks of tests with more than two stages in the literature. The benefit to cost values …

Economic Aesthetics, Ashrafi Sultana

College of Graduate Studies: Theses & Dissertations

Contemporary socio-economic reality is like a robbery, where the wealthy people have all the money, and the workers live from hand to mouth. These systematic inequalities are happening through capitalist consumerism and creating a growing economic contrast globally. Rather than considering imitative freedom promoted by the mainstream media that drives us to power, greed, or ego-centric mentality, I believe human rights can direct us to real freedom. In current society, basic rights are being taken away from many, while a great number of us are trapped in our utopian reality without recognizing the truth. We are stimulated by our socio-economic …

Does Race Have An Influence On The Athletic Trainer-Coach Relationship, Cayce M. Sloan

College of Graduate Studies: Theses & Dissertations

Introduction: Interpersonal relationships are the most frequent types of relationships individuals maintain on a daily basis. Rapport provides the foundation necessary to build positive interpersonal relationships, specifically, collegial relationships such as the relationship between the athletic trainer and coach. However, facilitators and barriers exist that may hinder relationships. Specifically, race appears to influence relationships, but to date, it appears race has not been examined in the athletic trainer-coach relationship. Therefore, the purpose of this study was to examine the facilitators and barriers to building rapport in race-discordant athletic trainer-coach relationships and to examine the role race plays within the athletic …

Characterization Of Functionalized Carbon Nanotubes And Polystyrene/Cnt Composites Prepared With Microwave-Induced Polymerization, Allen Hulette

College of Graduate Studies: Theses & Dissertations

The use of carbon nanotubes in polymer composites can increase the mechanical properties of the resulting product. Carbon nanotubes are known to have chemical interactions that make them attracted to one another and fall out of solution. To reduce this agglomeration and disperse the mechanical properties throughout the composite, functional groups are covalently added to the carbon nanotubes. Another known property of carbon nanotubes is their ability to absorb microwaves and convert it into other forms of energy. This research investigates the effects of carbon nanotube absorption of microwaves and initiation of styrene monomer polymerization. Grignard reactions are used to …

Mortality In Interspecific Hybrids Of Nasonia Vitripennis And Nasonia Giraulti, Bonnie Cobb

College of Graduate Studies: Theses & Dissertations

Nasonia is a parasitoid wasp genus that serves as an emerging model for studying speciation due to an incompatibility between nuclear and mitochondrial genomes between sister taxa. Short generation times, easy rearing in a lab setting, producing large amounts of progeny, and whole genome sequencing make Nasonia is an excellent candidate for studying incomplete reproductive isolation. Nasonia have five chromosomes and exhibit haplo-diploid sex determination in which fertilized eggs develop into diploid females and unfertilized eggs develop into haploid males. Recessive phenotypes are hidden in diploid females but are laid bare in haploid males as there is no interaction between …

Using Ai-Enabled Gaze Tracking System To Understand Comprehension Patterns Of Computer Science Students, Bradley Boswell

College of Graduate Studies: Theses & Dissertations

Academic institutions and instructors lack the ability to accurately assess the moment-to-moment attentiveness of students in classrooms where students’ faces are obscured by computer monitors. This can cause the lectures of Computer Science, Information Technology, or other lab-based courses to be incorrectly-paced, which can lead to students having an overall poorer grasp of the subject material. We propose a system for real-time accurate detection of classroom attentiveness using monitor-mounted webcams and eye trackers, along with a Convolutional Neural Network machine learning model (NiCATS). Through the use of a neural network, we produce an initial attentiveness score based on student webcam …

Developing And Validating A Machine Learning-Based Student Attentiveness Tracking System, Andrew L. Sanders

College of Graduate Studies: Theses & Dissertations

Academic instructors and institutions desire the ability to accurately and autonomously measure the attentiveness of students in the classroom. Generally, college departments use unreliable direct communication from students (i.e. emails, phone calls), distracting and Hawthorne effect-inducing observational sit-ins, and end-of-semester surveys to collect feedback regarding their courses. Each of these methods of collecting feedback is useful but does not provide automatic feedback regarding the pace and direction of lectures. Young et al. discuss that attention levels during passive classroom lectures generally drop after about ten to thirty minutes and can be restored to normal levels with regular breaks, novel activities, …

Coping Self-Efficacy As A Moderator In The Relationship Between Trauma And Disordered Eating, Bethany Owens Raymond

College of Graduate Studies: Theses & Dissertations

Disordered eating behaviors are associated with a myriad of detrimental health and mental health consequences (Ackard et al., 2003; Bryla, 2003; Karkkainen et al., 2018; Quick & Byrd-Bredbenner, 2013). Previous research identifies trauma as a risk factor for disordered eating behaviors and eating disorders (Brewerton, 2007). For instance, individuals with eating disorders are more likely to report trauma than individuals with no such history (Lejonclou et al., 2014). However, because not all individuals with a history of trauma exhibit disordered eating, it is important to identify what factors might moderate this relationship. The current study aims to investigate coping-self efficacy …

Determining Cause Of Failure For Load Cells Supporting Vertical Pressure Vessels Subject To Wind Loading, Seth Nowak

College of Graduate Studies: Theses & Dissertations

Wind loads cannot be avoided during a natural disaster such as a hurricane and could affect the strength and stability of vertical pressure vessels during exposure. Vertical pressure vessels cater to large wind loads; therefore, it is imperative to study the effect of additional loading on the structures. In this study, three pressure vessels with volumes of 50 CuFt, 200 CuFt, and 1100 CuFt, supported by three equidistant load cells under their legs are individually analyzed to determine von mises stress to estimate yield failure criteria. Two load rating criteria, maximum load capacity and water-filled condition (critical condition) are utilized …

Impostorism On Campus: The Effects Of Stereotype Threat On State Inauthenticity And State Anxiety In Two Samples Of African American College Women, Gabrielle Y. Johnson

College of Graduate Studies: Theses & Dissertations

Despite the growing education levels of Black women, negative stereotypes of Black women persist and undermine the confidence of African American/Black college women in the classroom. Experimental evidence supports that stereotype threat, the fear of confirming a negative stereotype about one’s group when being evaluated by others, undermines the performance of high achieving Black students (Steele & Aronson, 1995). Research has found the impostor phenomenon to be experienced as thoughts of inauthenticity, in conjunction with fear of failure and being exposed as a fraud (Ibrahim et al., 2020). Therefore, being continuously exposed to situations that create feelings of state inauthenticity, …

License Plate Image Quality Enhancement Utilizing Super Resolution Generative Adversarial Networks, Mark Moelter

College of Graduate Studies: Theses & Dissertations

This thesis focuses primarily on enhancing the image quality of blurred license plates through the use of Super-Resolution Generative Adversarial Networks (SRGANs) [1]. We propose a synthetic dataset with SRGAN model to promote blurred image quality enhancement, and allow for model evaluation on a multitude of image input and output size combinations. SRGAN is mainly used for low-resolution image enhancement, but by heavily blurring the input images, the model is tested on its ability to blindly deblur and upsample images to the desired super-resolution (SR) size. The model enhances the image quality to nearly that of the reference images. The …

Synthesis And Characterization Of Multimetallic Clusters Featuring Iron, Cobalt, And 2,6-Bis(Trialkylsilylamino)Pyridines, Lynn Nguyen

College of Graduate Studies: Theses & Dissertations

Extended metal atom chain (EMAC) complexes are multimetallic complexes of three or more metals, often containing M-M bonds, with the metal ions arranged linearly. These complexes have significant potential as molecular wires. They can elicit unique physical properties and reactivities, sometimes a result of direct magnetic exchange between metal centers, especially when incorporating first row transition metals. The synthesis of the first linear, triiron (II) complex with 2,6-bis[(trimethylsilyl)amino]pyridine (H₂L^Me) featuring Fe-Fe bonding from our group, Fe₃L^Me₃, motivated the expansion of linear multimetallic EMAC complexes with Fe and Co, incorporating M-M bonds. …
