Mapping Relational Algebra Operators Into Sql Queries: A Database Case Study, John N. Dyer, Camille F. Rogers

Information Systems & Analytics: Faculty Publications

Relational algebra operators and mapping to resulting structured query language (SQL) queries are among the most important concepts and skills for students taking a course in database design and implementation, especially those majoring in IS/IT. The most typical relational algebra operators mapped to foundational SQL include unions and intersections, as well as other relational operators applied to these operators, including differences and various joins. Unfortunately, few textbooks or external resources provide ample opportunity for students to apply the full set of most common relational algebra operators mapped to resulting SQL over a single unified case. Most database textbooks exemplify each …

History Of Concussion And Current Functional Movement Screen Scores In A Collegiate Recreational Population, Jordan M. Dorrien

College of Graduate Studies: Theses & Dissertations

Introduction: 1.6-3.8 million concussions occur annually related to sport.¹ Although neurometabolic alterations in the brain last 7-10 days following a concussion, an increased Cortical Silent Period (CSP) has been found to persist after 19 months.^2,3 Further, movement impairments have been noted years after injury.⁴ The Functional Movement Screen (FMS) assesses mobility and stability in the body.⁵ The purpose of this study was to assess if FMS scores correlate to history of a concussion in healthy college club sport participants. Methods: Health history and FMS score were collected on 55 participants (38 male, …

Using A Delayed Match-To-Samples Task To Investigate The Isolated Processing Of Geometric Shapes And Their Corresponding Shape Words, Joshua E. Edwards

College of Graduate Studies: Theses & Dissertations

Evidence suggests an isolated system dedicated to processing geometric information (Spelke, Lee, & Izard, 2010), but isolating geometric processing from semantic processing has remained difficult. Recently, Sturz, Edwards, and Boyer (2014) utilized a delayed match-to-sample (DMTS) task to present participants with a sample composed of a shape, shape word, or a bi-dimensional stimulus composed of a shape and a shape word. After a delay, participants were required to identify the sample shape or the sample word by selecting between two shapes or two shape words. Results suggested that sample shapes did not interfere with selecting a correct match in the …

The Anatomy Of Disgust And The Sublime In Metamodern Painting, Claudia L. Furlow

College of Graduate Studies: Theses & Dissertations

The works in this series explore the application of Platonic binary oppositions of life/death and attraction/repulsion using Renaissance painting techniques that include the application of solvent and linseed oil glazes, as well as Galkyd Lite and MSA Gel, to assist in the realistic replication of the flesh of animals that meet death at the hand of humans, by attack of other animals, or through mishaps with motor vehicles. Informed by the work of Ambrosius Bosschaert the Younger, Jan Fyt, Rembrandt van Rijn, Théodore Géricault, Francis Bacon, Joel-Peter Witkin, Walton Ford, Jenny Saville, and Victoria Reynolds, this study documents the evolution …

Confabulation, Ruth Lakhani

College of Graduate Studies: Theses & Dissertations

I create work that is an investigation of memory- individual memories from a single location over a span of time. Over time, these individual memories are layered on top of each other to become remembered as one. When the boundaries between the original and successive memories become unstable and unreliable false memories are produced.

My sculptures are non-literal representations of selected interior details from my memories of a place that I visited regularly throughout my life. This place that I am inspired by has undergone several different stages of repair, from when the house was first constructed up to the …

Assessment Of Electrode Configurations Of Electrical Impedance Myography For The Evaluation Of Neuromuscular Diseases, Khondokar Mohammad Fazle Rabbi

College of Graduate Studies: Theses & Dissertations

Electrical impedance myography (EIM) is a painless, noninvasive approach to measure the neuromuscular disease status. EIM parameters- resistance (R), reactance (X) and phase (θ) depend significantly on subcutaneous fat thickness, muscle size and inter electrode distance. The objective of this research is to find an electrode configuration which can minimize the effects on EIM parameters due to subcutaneous fat thickness variation. In this study, a model of human upper arm was developed using finite element method (FEM), which has already been established as an appropriate approach for the analysis of non-symmetrical shape for assessing alternations of muscle in disease-induced changes …

Design And Implementation Of An Interactive Animatronic System For Guest Response Analysis, Brian Burns

College of Graduate Studies: Theses & Dissertations

In theme park based entertainment applications, there is a need for interactive, autonomous animatronic systems to create engaging and compelling experiences for the guests. The animatronic figures must identify the guests and recognize their status in dynamic interactions for enhanced acceptance and effectiveness as socially interactive agents, in the general framework of human-robot interactions. The design and implementation of an interactive, autonomous animatronic system in form of a tabletop dragon and the comparisons of guest responses in its passive and interactive modes are presented in this work. The dragon capabilities include a four degrees-of-freedom head, moving wings, tail, jaw, blinking …

Helping To Resolve Taxonomic Conflicts Within The Genus Amblyomma (Acari:Ixodidae) From A Molecular Perspective, Paula Lado

College of Graduate Studies: Theses & Dissertations

This work sought to reassess the taxonomic status of Amblyomma parvum Aragao, 1908 and of the A. maculatum group of ticks Camicas, 1998. By using different molecular markers, 12SrDNA, 16SrDNA, DL, COI, COII (mitochondrial) and ITS2 (nuclear), I analyzed the systematic relationships between these taxa and their closest relatives. Phylogenetic analyses by maximum parsimony, maximum likelihood, and Bayesian analysis were performed in order to determine relationships among species and populations, and to determine the evolutionary history of these ixodids. The data obtained supported the hypothesis of cryptic speciation occurring within A. parvum, with the northern populations of Central America being …

Female Social Rank And Steroid Production In Semi-Free Ranging Lemur Catta On St. Catherines Island, Georgia, Tiffany Burgess

College of Graduate Studies: Theses & Dissertations

Many mammalian species live in complex social groups that profoundly affect the behavior and ecology of their members. In ring-tailed lemurs (Lemur catta) these groups are characterized by female dominance, where females have priority over males for food, grooming, and space. Among females there is also a linear dominance hierarchy. L. catta have a strong matrilineal social core due to females staying within their natal group and males dispersing at sexual maturity. Daughters “inherit” their mother’s social rank. However, it is not known if the matrilineal lines are maintained through learned dominant/aggressive behavior or inherited via genetically determined hormonal …

Myosinx Is Required For Craniofacial Development In Danio Rerio, Cole Yancey

College of Graduate Studies: Theses & Dissertations

Craniofacial development is the process of laying early cartilage and bone patterns in the anterior region of the embryo, which ultimately results in shaping the structure of the face and head of an organism. Craniofacial abnormalities in humans, such as cleft lip and palate, are among the most common of all birth defects. Therefore, investigating the molecular mechanisms involved in craniofacial development will help us understand both evolutionary processes and genetic diseases. Craniofacial cartilage and bone structures are almost entirely derived from neural crest cells. Neural crest are a pluripotent migratory stream of cells that originate from the early developing …

Ammonia Oxygen Demand Determination For The Design Of An Oxygenation System In A Water Supply Reservoir, Armond Jenkins

College of Graduate Studies: Theses & Dissertations

The Occoquan Reservoir is a eutrophic reservoir that is part of an indirect potable reuse system. To protect the reservoir water quality, a high quality nitrified product water from a water reclamation facility and an oxygenation system are used during periods of thermal stratification to prevent the onset of anaerobic conditions above the sediments. During the stratified warmest months of the year, oxygen depletion rates exceed nitrate and artificial oxygen supply rates near the dam resulting in ammonia accumulation in the water column. Field observations and laboratory experiments revealed that sediment ammonia release rates ranged from 170-542 mg/m²∙day. …

Excessive Tanning As A Presentation Of Body Dsymorphic Disorder, Jennifer Headrick

College of Graduate Studies: Theses & Dissertations

Body dysmorphic disorder (BDD) involves a potentially debilitating preoccupation with an imagined or minor flaw in one’s appearance (American Psychiatric Association, 2013; Phillips, 2005). Common body areas of preoccupation include the skin, face, hair, and muscles (Castle, Ross, & Kyrios, 2006; Mosley, 2009; Phillips, 2005; Veale, 2003). With the publication of the Diagnostic and Statistical Manual of Mental Disorders—5th edition (APA, 2013), BDD was moved from the Somatoform Disorder classification to the new diagnostic category of Obsessive-Compulsive and related disorders. A new example of preoccupation with skin tone and an associated behavior of excessive tanning were added to the BDD …

The Physiological Stress Response Caused By Hypoxia And Reperfusion Injury In Striped Bass (Morone Saxatilis) And Nile Tilapia (Oreochromis Niloticus), Amanda C. Reynolds

College of Graduate Studies: Theses & Dissertations

Approximately five million people in the United States are affected by cardiovascular related diseases yearly contributing to 300,000 annual deaths, making CVD the leading cause of mortality worldwide. It has been suggested that apoptosis (programmed cell death) contributes to the pathogenesis of cardiovascular diseases. When blood flow is reduced or cut off from the heart, usually by a thrombus, this results in oxygen deprivation (hypoxia) to the cardiomyocytes (heart cells). In response to this hypoxic stress, cardiomyocytes will undergo apoptosis. Since many species of fish can survive levels of hypoxia that would be fatal to mammals, fish are an ideal …

Public Health Implications Associated With The Practice Of Utilizing Tires To Singe Meat In Three Major Cities Of Ghana: A Concurrent Mixed Methods Study, Tempest D. Hill

College of Graduate Studies: Theses & Dissertations

Utilization of automobile tires to singe meat (e.g., cows) intended for human consumption presents public health risks due to hazardous chemicals released into the environment and meat. This has become a common practice in some African countries such as Ghana. The objective of this study was to investigate the awareness and perception of the residents in three major cities of Ghana (Cape Coast, Kumasi and Accra) using the Health Belief Model and Social Ecological Model. Survey participants (n=196) and focus group discussion members (n=37) completed the study. Data collected from study participants included meat consumption, awareness of the use of …

Genetic Structure Of Ixodes Scapularis Say 1821 (Acari: Ixodidae), The Blacklegged Tick, By Microsatellite Analysis, John Ludwig

College of Graduate Studies: Theses & Dissertations

The blacklegged tick, Ixodes scapularis (Acari: Ixodidae) is the subject of intense research due to its economic importance from being a vector of several diseases. Previous studies have examined its taxonomic status and more recently, its genetic structure. This study embarked upon resolving the questions surrounding the genetic structuring of the tick, by using different molecular markers. Molecular data were first phylogenetically analyzed by using four different mitochondrial and nuclear markers (12SrDNA n=483, Dloop n=432, ITS2 n=156, Actin n=117). A Bayesian tree was inferred from the concatenated mitochondrial dataset, whereas nuclear gene markers were found to be uninformative. Nine microsatellites …

Young, Gifted, Black, And Blocked: A Critical Inquiry Of Barriers That Hinder Black Students' Participation In Gifted And Advanced Placement Programs, Elizabeth Anne Evans

College of Graduate Studies: Theses & Dissertations

This inquiry explores the underrepresentation of Black students in the Gifted and Advanced Placement (AP) Program from the perspective of the student. This study focused primarily on the barriers students perceived that hindered their participation. In addition, I explored the role teachers and guidance counselors play in Black students’ decisions to enroll or drop out of AP classes, and how the history and institution of gifted educations has aid and excluded Black students. Five Black high school students, four male, and one female, were interviewed.

Theoretically, my study was grounded in two distinct inquiries; Critical Theory (Kincheloe & McLaren, 2008) …

The Reproductive Cycle Of The Guatemalan Beaded Lizard, Heloderma Charlesbogerti, Wade C. Carruth Iii

College of Graduate Studies: Theses & Dissertations

Reproductive information, including seasonality in behavior and physiology, is key to our ability to breed species for maintaining assurance colonies or for future introductions. Limited scientific data is available about the reproduction of Helodermatid lizards. Several species of helodermatid lizard are uncommon, rare, or simply exist at low population densities and in need of the development of conservation programs and management. Most helodermatid reproductive data collected to date has been done on deceased animals using histological techniques. Until this study, no hormones have been analyzed, and individual animals have not been followed through a complete cycle. The purpose of this …

Computational Fluid Dynamics Modeling Of The Effects Of Water Injection In A Diesel Engine, Rabun Z. Wallace

College of Graduate Studies: Theses & Dissertations

Water injection has been used in internal combustion engines for many years. It has been used to cool combustion temperatures, reduce emissions, and in some instances clean carbon buildup from the cylinder. Research has shown that the water to fuel mass ratio is most effective between 20-30%, so the upper and lower limit were used for simulations in Converge CFD. To validate the CFD model, a case without water injection was compared to experimental data from Sandia National Laboratory. The predicted in-cylinder pressure and heat release rate showed good agreement with the experimental data. Cases were run with the injection …

Understanding Each Other - Developing Positive Relationships With Challenging Students, Ann M. Van Buskirk Ph.D., Kimberly Oliver Robinson Ph.D.

Georgia Association for Positive Behavior Support Conference

Everyone has encountered someone who is hard to like and may not "fit" well with our own personality. As parents, we do not choose the temperament of our children, and as educators we often do not choose the students in our classroom. Studies have suggested that for every 10 students, 2-3 will be a "perfect match" for the teacher, 6-7 may be a “good fit” and often at least one student will present significant challenges for her or his teacher. Many of the challenges faced by parents and educators in working with students are exacerbated by lack of understanding and …

Using Ti-Nspire To Engage Preservice Mathematics Teachers In An Exploratory Geometry Module, Alesia D. Mickle, Pier A. Junor Clarke

Proceedings of the Annual Meeting of the Georgia Association of Mathematics Teacher Educators

In the mathematics classroom, most preservice mathematics teachers possess basic skills to use technology as an instructional strategy in communicating content standards. However, today’s demands for preservice teachers to engage in a variety of “best teaching practices” in their preservice teaching and edTPA requirements can oftentimes place the acquisition of technical skills and integration of new technology in content curriculum far from the forefront of their minds. Ertmer, Conklin, Lewandowski, Osika, Selo, and Wignall (2003) acknowledged preservice teachers’ desires to gain the adequate technical skills necessary to use technology in teachers’ daily tasks of facilitating and managing their classrooms. They …

Challenges Posed By Tick-Borne Rickettsiae: Eco- Epidemiology And Public Health Implications, Marina E. Eremeeva, Gregory A. Dasch

Environmental Health Sciences: Faculty Publications

Rickettsiae are obligately intracellular bacteria that are transmitted to vertebrates by a variety of arthropod vectors, primarily by fleas and ticks. Once transmitted or experimentally inoculated into susceptible mammals, some rickettsiae may cause febrile illness of different morbidity and mortality, and which can manifest with different types of exhanthems in humans. However, most rickettsiae circulate in diverse sylvatic or peridomestic reservoirs without having obvious impacts on their vertebrate hosts or affecting humans. We have analyzed the key features of tick-borne maintenance of rickettsiae, which may provide a deeper basis for understanding those complex invertebrate interactions and strategies that have permitted …

Gang Risk Factors And Academic Readiness In A Southern Middle School, James Martinez, Jeremy Tost, Shani Wilfred, Larry Hilgert

Georgia Educational Researcher

The current Georgia study examines middle-school-aged gang and non-gang members regarding the risk factors of gang membership and potential effects of these risk factors on academic achievement. Participants, 406 eighth grade students from a suburban middle-school, completed a 42-item survey assessing an array of demographic and risk factor variables. In addition, students provided self-report information regarding their success on national standardized testing used to measure academics readiness. Of the 28 variables analyzed, lower academic readiness was associated with ethnicity and/or gang membership. Findings are discussed in light of the complexity of the gang issue and the importance of recognizing the …
