Evaluating Elasmobranch Bycatch And Shark Depredation In The Georgia Shrimp Fishery, Matthew M. Scanlon
Evaluating Elasmobranch Bycatch And Shark Depredation In The Georgia Shrimp Fishery, Matthew M. Scanlon
Electronic Theses and Dissertations
The Georgia shrimp fishery has seen a dramatic decrease in profit and productivity since the 1980’s due to a number of economic factors. Additional, yet undocumented, pressures on this fishery include interactions between foraging sharks with trawl gear. Fishermen report that sharks frequently bite nets in an attempt to prey on netted fish, resulting in large holes in the gear. Further elasmobranch interactions with trawl gear occur as bycatch; shrimp trawls represent nearly 100% of elasmobranch commercial bycatch in Georgia state waters, the species composition of which is largely unstudied. Shark interactions with nets were detailed through fishery-dependent observations on …
The Effects Of Preceding Stimuli Formats On Proportional Reasoning Ability In Elementary School Students, Natalie D. Branch
The Effects Of Preceding Stimuli Formats On Proportional Reasoning Ability In Elementary School Students, Natalie D. Branch
Electronic Theses and Dissertations
The National Mathematics Advisory Panel (2008) described fraction knowledge as the most important, yet most underdeveloped foundational skill among students. Due to the complex nature of fraction education, this study sought to understand the underlying fraction problem-solving skill of proportional reasoning in the hopes of gaining insight into children’s problem-solving strategies in order to implement more focused educational designs. The current study examined the effects of stimuli formats on children’s proportional reasoning ability by presenting four conditions involving two formats (continuous and discrete). Previous research indicates that students perform better on continuous stimuli and the goal of this study was …
Environmental And Physiological Regulation Of Yellow Stingray Color Change, Theresa Rose Gunn
Environmental And Physiological Regulation Of Yellow Stingray Color Change, Theresa Rose Gunn
Electronic Theses and Dissertations
Many reef fishes exhibit dynamic coloration and body patterns that can change under nervous or hormonal control. Several species of benthic sharks and rays likely alter melanin in the skin to provide background matching for camouflage. The yellow stingray (Urobatis jamaicensis) is a benthically-oriented elasmobranch with elaborate spot patterns that provide effective camouflage within its habitats. This patterning, when coupled with the ability to alter melanin in response to background color, could increase background matching effectiveness in these species. The yellow stingray has been anecdotally noted to lighten or darken skin color.However, it is unclear whether this type …
Predictors Of Fish Assemblage Structure And Dynamics In Atlantic Coastal Plain Streams, Rebecca Scott
Predictors Of Fish Assemblage Structure And Dynamics In Atlantic Coastal Plain Streams, Rebecca Scott
Electronic Theses and Dissertations
Effective management of freshwater fishes requires a mechanistic understanding of the drivers of assemblage composition; in other words, what determines who is where and when. Stream fish assemblages are potentially influenced by environmental factors that act on multiple spatiotemporal scales, but the relative influence of these drivers may vary between geophysically distinct regions. This study sought to determine the patterns and drivers of fish taxonomic and functional assemblage composition in the coastal plain, a region possessing unique hydrologies, faunas, and physiochemical conditions. I addressed this goal using two complementary chapters, both of which utilized environmental and biotic data collected from …
The Miseducation Of Irie Jones In Zadie Smith's White Teeth, Amanda S. Medlock
The Miseducation Of Irie Jones In Zadie Smith's White Teeth, Amanda S. Medlock
Electronic Theses and Dissertations
In this essay, I will discuss Carter G. Woodson’s notion of the “mis-education” black Americans face and its applicability in British novelist, Zadie Smith’s, debut novel, White Teeth. This novel shows how mis-education affects four generations of female Caribbean migrants. My analysis emphasizes how this mis-education shapes the life of Smith’s character, Irie Jones. Throughout the text, Irie suffers from low self-esteem due to her cultural rootlessness. I attribute this rootlessness to the mis-education inherited from her female predecessors. Ultimately, I explore how instead of defeating this familial baggage, she falls victim to it.
Exploring Psychosocial Factors And Sexual Risk Behavior Of Men Who Have Sex With Men In The United States Military: Project Minds, Erin Jordan

Statement of the Problem: Men who have sex with men (MSM) are at disproportionate risk for HIV infection. While many studies have examined psychosocial factors associated with HIV risk among MSM, few have focused specifically on MSM in the military. The purpose of this exploratory study is to examine ways in which specific psychosocial factors are associated with sexual risk behaviors among MSM in the military.
Methods: Data were collected from 63 MSM who were active duty military personnel or veterans in the Southeastern US. Participants were recruited from geosocial mobile applications, social media platforms, and military LGBT organizations. Logistic …
The Effects Of Alcohol Priming On Age Perception And Attractiveness Ratings, Brooks B. Kolberg
The Effects Of Alcohol Priming On Age Perception And Attractiveness Ratings, Brooks B. Kolberg
Electronic Theses and Dissertations
Sexual assault and alcohol have often been linked together (Abbey et.al, 2004; Collins & Messerschmidt, 1993). Also, 29% of rape victims are between the ages of 12 and 17 (Greenfield, 1997). Research suggests people who are more impulsive are more likely to be sexually aggressive (Mouilso, Calhoun, & Rosenbloom, 2013); however, less is known regarding the underlying mechanisms of the relationship between alcohol and sexual assault of minors. This study addressed this knowledge gap by (1) examining the effects of alcohol priming on attractiveness ratings and age perception of individuals who could be perceived as adolescent, and (2) investigating the …

Modeling, Designing And Analysis Of A Standalone Pv Dc Microgrid System, Sharaf Sumaiya
Electronic Theses and Dissertations
The increasing concern about global warming, the upsurge of oil prices, and pollution of petroleum energy has led scientists to search for cost-effective energy sources, for example, photovoltaics. Recently DC microgrids have also drawn more consideration because of the expanding use of direct current (DC) energy sources, energy storages and loads in power systems. First, as a groundwork, the 1D organic solar cell has been investigated that leads to design 3D organic solar cell. Then design and analysis of a standalone solar PV system with dc microgrid has been proposed to supply power for both DC and AC loads. The …

In this thesis, we consider the properties of sparse trees and summarized a certain class of trees under some constraint (including with a given degree sequence, with given number of leaves, with given maximum degree, etc.) which have maximum Wiener index and the minimum number of subtrees at the same time. Wiener index is one of the most important topological indices in chemical graph theory. Steiner k�� Wiener index can be regarded as the generalization of Wiener index, when k = 2, Steiner Wiener index is the same as Wiener index. Steiner k�� Wiener index of a tree T is …
The Role Of Shame: A Creative Look At Justice, Gabrielle Lory
The Role Of Shame: A Creative Look At Justice, Gabrielle Lory
Electronic Theses and Dissertations
The current criminal justice system is often brought under scrutiny for its perceived lack of procedural justice, low rates of victim satisfaction and a pattern of sentencing disparities among populations of racial minorities and people of low socioeconomic status (Palmer, 2015; Hamilton, 2017; Cornwell & Waite, 2009). Alternative justice programs have been growing in number for decades, as well as continually developing their processes to improve outcomes for victims and ameliorate sentencing disparities. This study examines the extant literature on alternative sentencing programs, specifically restorative justice programs, to provide empirical evidence contributing to the development of a creative justice framework …
Isolated Mobile Malware Observation, Augustine Paul
Isolated Mobile Malware Observation, Augustine Paul
Electronic Theses and Dissertations
The idea behind Bring Your Own Device (BYOD) it that personal mobile devices can be used in the workplace to enhance convenience and flexibility. This development encourages organizations to allow access of personal mobile devices to business information and systems for businesses operation. However, BYOD opens a firm to various security risks such as data contamination and the exposure of user interest to criminal activities. Mobile devices were not designed to handle intense data security and advanced security features are frequently turned off. Using personal mobile devices can also expose a system to various forms of security threats like malware. …

Comparison Of Three Benthic Macroinvertebrate Passive Sampling Devices For Non-Wadeable Streams, Kelsey A. Laymon
Comparison Of Three Benthic Macroinvertebrate Passive Sampling Devices For Non-Wadeable Streams, Kelsey A. Laymon
Electronic Theses and Dissertations
Rivers and streams provide essential ecosystem services to the degree that the monitoring and maintenance of these systems becomes imperative. Biomonitoring provides managers and policymakers with the tools to make informed decisions, and macroinvertebrates are often the object of biomonitoring because they are ubiquitous in most systems and are known to be good indicators of water quality. However, methods for sampling macroinvertebrates in non-wadeable streams (i.e., large rivers) have not been standardized across states and regions and an established method for macroinvertebrate biomonitoring in large rivers of Georgia is not currently available. My study compared macroinvertebrates collected with three types …
Characterizing The Complex Relationship Between The Brown Widow Spider And Its Bacterial Endosymbiont, Wolbachia, Emily Knight
Characterizing The Complex Relationship Between The Brown Widow Spider And Its Bacterial Endosymbiont, Wolbachia, Emily Knight
Electronic Theses and Dissertations
The brown widow spider, Latrodectus geometricus (C. L. Koch 1841), has been found to harbor the maternally inherited bacterial endosymbiont Wolbachia pipientis (Hertig and Wolbach 1924), but endosymbiont infection frequency varies widely among Southeastern US populations. Wolbachia is known to manipulate the reproduction of its hosts through male feminization, parthenogenesis, male killing, and cytoplasmic incompatibility. In brown widows, Wolbachia does not alter sex ratios, but any other effects the symbiont has on the spider are unknown. In my first chapter, I assess if there is linkage between Wolbachia infection and maternally inherited mitochondrial DNA (mtDNA) in three brown widow populations. …

A Meta-Assessment Of An Institution's Administrative Assessment Processes, Cynthia Groover
A Meta-Assessment Of An Institution's Administrative Assessment Processes, Cynthia Groover
Electronic Theses and Dissertations
Many institutions establish assessment teams to assist faculty in developing their knowledge of and confidence in conducting academic program assessment, and some extend these teams to address administrative and student affairs assessment as well. These teams may function as more formal distributed leadership models, as described by Spillane (2006), or they may be less formal groups with little or no leadership roles. Regardless of their level of formality, these teams are often used to implement other resources such as rubrics, peer review, and feedback, but the effectiveness of these resources and processes is not commonly reviewed through an intentionally designed …

(Re)Learning To Question: Curriculum Studies And (Re)Thinking Science For The 21st Century, Anthony Jerome Stawiery
(Re)Learning To Question: Curriculum Studies And (Re)Thinking Science For The 21st Century, Anthony Jerome Stawiery
Electronic Theses and Dissertations
This dissertation proposes a science literacy which revisits the nature of science and how it has fallen away from its inquiry-based roots and has become a tool for oppression and exclusion. The epistemological roots of science begin with curiosity and questioning. Asking questions is also foundational to democratic society. A critical science literacy emphasizes the need to question and to remain curious. Such skills can be incorporated across multiple disciplines. Therefore, this dissertation proposes science literacy not as a literacy in the life or physical sciences, but as a methodology of inquiry, a skillset that nurtures curiosity and strengthens critique. …
A Journey To The Adic World, Fayadh Kadhem
A Journey To The Adic World, Fayadh Kadhem
Electronic Theses and Dissertations
The first idea of this research was to study a topic that is related to both Algebra and Topology and explore a tool that connects them together. That was the entrance for me to the “adic world”. What was needed were some important concepts from Algebra and Topology, and so they are treated in the first two chapters.
The reader is assumed to be familiar with Abstract Algebra and Topology, especially with Ring theory and basics of Point-set Topology.
The thesis consists of a motivation and four chapters, the third and the fourth being the main ones. In the third …
Does Observational Learning Influence Spatial Pattern Learning?, Matthew Bruster
Does Observational Learning Influence Spatial Pattern Learning?, Matthew Bruster
Electronic Theses and Dissertations
Previous studies have indicated both human and non-human animals come under control of a hidden spatial pattern when engaged in an open field search task, and rats appear to exhibit social learning in such tasks through the influence of a conspecific on their search behavior. Although human participants appear to perform similarly in both real-world and virtual environment versions of a spatial pattern search task, evidence from human participants for social learning in such a task remains lacking. The current experiments tested the influence of social learning (observational learning) on human performance in a spatial pattern learning task within a …
The Exertion Of A Choice: An Ecofeminist Vision ~ Aesthetic, Embodied, And Connected Learning, Sharon M. Eswine
The Exertion Of A Choice: An Ecofeminist Vision ~ Aesthetic, Embodied, And Connected Learning, Sharon M. Eswine
Electronic Theses and Dissertations
In this dissertation, I build upon Darwin’s (1859/1964) metaphor of the complex biological tangle of a river bank - plants, birds, insects, and earth - to paint a picture of transformative learning as aesthetic (Dewey, 1934/2005; Eisner, 1998, 2002b; Greene, 1995, 2001; Liston, 2001), and embodied (Dewey, 1958; Johnson, 2007; Shusterman, 2006), and thereby connected to the learner’s life experience, including his/her/their ecological, cultural, and historic situatedness. I call this complication of Darwin’s metaphor the ecofeminist tangled bank. For my purposes, an ecofeminist theoretical framework provides a means of analyzing oppressive conceptual frameworks that perpetuate hierarchy and domination, and which …
Examining The Collegiate Experiences Of African American Males With Same Race Mentors, Crystal L. Locke
Examining The Collegiate Experiences Of African American Males With Same Race Mentors, Crystal L. Locke
Electronic Theses and Dissertations
African American males have a more meaningful college experience when they are mentored with people with whom they can culturally relate (Brown, 2013; Moore & Tolliver, 2010). Although studies indicate African American males who had same race mentors display higher self-efficacy (Stefon, 2011), improved graduation rates (U.S. Department of Education, 2017), and a more positive college experience (Chen, Ingram & Davis, 2014), additional research in this area is needed.
Using a phenomenological approach, this qualitative study sought to determine the impact having a same race mentor had on the collegiate experiences of five African American males who successfully graduated from …

Introduction: Childhood obesity is a growing public health problem. In the US, over 13.7 million children are obese. Specifically in Georgia, childhood obesity among children between ages 10 – 17 is the 8th highest in the nation. Rural Georgia has disproportionately higher rates of overweight and obesity than urban areas of Georgia. Schools are an ideal venue through which to address childhood obesity because many US children consume up to half of their daily calories at school. The aim of this research was to determine the facilitators and barriers to implementing farm to school activities from the perspective of …
Multiclass Classification Using Support Vector Machines, Duleep Prasanna W. Rathgamage Don
Multiclass Classification Using Support Vector Machines, Duleep Prasanna W. Rathgamage Don
Electronic Theses and Dissertations
In this thesis, we discuss different SVM methods for multiclass classification and introduce the Divide and Conquer Support Vector Machine (DCSVM) algorithm which relies on data sparsity in high dimensional space and performs a smart partitioning of the whole training data set into disjoint subsets that are easily separable. A single prediction performed between two partitions eliminates one or more classes in a single partition, leaving only a reduced number of candidate classes for subsequent steps. The algorithm continues recursively, reducing the number of classes at each step until a final binary decision is made between the last two classes …

In this paper we present a survey of results on the Schrodinger operator with Inverse ¨ Square potential, La= −∆ + a/|x|^2 , a ≥ −( d−2/2 )^2. We briefly discuss the long-time behavior of solutions to the inter-critical focusing NLS with an inverse square potential(proof not provided). Later we present spectral multiplier theorems for the operator. For the case when a ≥ 0, we present the multiplier theorem from Hebisch [12]. The case when 0 > a ≥ −( d−2/2 )^2 was explored in [1], and their proof will be presented for completeness. No improvements on the sharpness …
Mindful Escapism, Kench Weathers
Mindful Escapism, Kench Weathers
Electronic Theses and Dissertations
This thesis examines the art work included in Kench Weathers’ MFA thesis exhibition. This work explores major themes such as the sacred, contemplation, optical illusion and paradox. The installations involve multiple three-dimensional geometric shapes that are formed with steel tubing (welded together). These works have various inspiration; both contemporary secular and sacred and are influenced by sacred paradox, both visual and ideological. The mixture of the two-dimensional with the three-dimensional creates multistable perception within the viewer. The work introduces visual and perceptual distortions of depth and dimensionality. These forms are nonrepresentational but act as a catalyst for the viewer. I …
