The Role Of Habitat Management In Shaping Predation, Animal Color, And Gene Flow In A Metapopulation Of Florida Scrub Lizards (Sceloporus Woodi), Richard William Orton Jan 2017

The Role Of Habitat Management In Shaping Predation, Animal Color, And Gene Flow In A Metapopulation Of Florida Scrub Lizards (Sceloporus Woodi), Richard William Orton

College of Graduate Studies: Theses & Dissertations

Anthropogenic disturbance is known to affect biological diversity at the community, species, and genetic levels. Habitat fragmentation, in particular, has been shown to impact predator abundance and distribution, impede dispersal, and augment genetic drift. In small populations, which often result from habitat fragmentation, the effects of human disturbance may be disproportionately expressed. Small populations are more susceptible to selection pressures and random drift because genetic and phenotypic frequencies can become rapidly fixed, in comparison to larger populations. In turn, fixation of maladaptive alleles or morphs can accelerate extinction. For example, cryptic color polymorphism can be maintained by apostatic selection, where …


Antibiotics And Antibiotic-Resistant Bacteria In Coastal Plain Streams, Jason Duff Jan 2017

Antibiotics And Antibiotic-Resistant Bacteria In Coastal Plain Streams, Jason Duff

College of Graduate Studies: Theses & Dissertations

Streams across the United States and globally are influenced by environmental contamination, including antibiotics, which enter streams due to widespread use and multiple pathways into the environment. Antibiotics are also likely to enter streams in mixture with other contaminants that alter the effects on aquatic organisms. Furthermore, antibiotic-resistant bacteria enter streams through similar pathways as antibiotics with implications for natural microbial communities. Therefore, understanding the presence and effects of antibiotic-contaminant mixtures and antibiotic-resistant bacteria in streams is important for resource management.

Chapter one describes an experiment that tested the hypothesis that the antibiotic tetracycline (TC) alone influences phytoplankton communities differently …


Cultivating Ecological Literacy And Rethinking Our Connections To Nature, Sean Fretwell Jan 2017

Cultivating Ecological Literacy And Rethinking Our Connections To Nature, Sean Fretwell

College of Graduate Studies: Theses & Dissertations

In this dissertation I explore the complex, often contested, relationships between humankind and nature. I consider the changing state of these relationships as they are influenced by factors rooted in science, technology, and economics. I also examine these relationships as they relate to human activities with agriculture. Considering the present state of environmental crisis and the abundance of evidence indicating the deleterious activities of humankind as primary causes for the many global calamities, I argue for revising industrially-driven ideologies; particularly those driven by the economic paradigm of capitalism and self-interest. Additionally, I submit that a return to kinship with nature …

The Effect Of Acute Thermal Stress On Gene Expression Levels Of Hsp70 In The Antarctic Notothenioid, Notothenia Coriiceps, Eudiah Ochieng Jan 2017

The Effect Of Acute Thermal Stress On Gene Expression Levels Of Hsp70 In The Antarctic Notothenioid, Notothenia Coriiceps, Eudiah Ochieng

Honors College Theses

The waters of the West Antarctic Peninsula are known as one of the most cold, stable environments on earth and organisms living within, such as the fish Notothenia coriiceps, have become highly specialized over evolutionary time. However, water temperatures in this environment have been steadily warming over the past two decades due to global climate change. In addition to the challenges created by increasing temperatures N. coriiceps will also be faced with difficulty meeting oxygen demands to carry out metabolic processes due to the decrease solubility of oxygen in warmer environments. Heat stress proteins (Hsps) are critical molecules that …


An Analysis Of White-Tailed Deer, Odocoileus Virginianus, Killed In Deer Vehicle Accidents On Bulloch County, Ga Roadways, Mackenzie P. Payne 4003933 Jan 2017

An Analysis Of White-Tailed Deer, Odocoileus Virginianus, Killed In Deer Vehicle Accidents On Bulloch County, Ga Roadways, Mackenzie P. Payne 4003933

Honors College Theses

White-tailed deer, Odocoileus virginianus, are native to Georgia. With over 1.2 million individuals in the state, White-tailed deer have been implicated in a large number of motor vehicle collisions (ca. 1 million) each year. It is unknown, however, if deer are more likely to be killed: 1) if they are of particular ages (or classes), and 2) in areas with specific road characteristics. We addressed these two questions by collecting the remains of 20 White-tailed deer killed in deer vehicle collisions (“deer vehicle accidents” - DVAs) in Bulloch County, GA. When a deer was located, the road characteristics were …


School Shootings Perpetrators' Self-Reported Motives: A Qualitative Analysis Of Manifestos And Other Writings, Stephanie A. Miller Jan 2017

School Shootings Perpetrators' Self-Reported Motives: A Qualitative Analysis Of Manifestos And Other Writings, Stephanie A. Miller

Honors College Theses

The motivations behind perpetrators decisions to commit a school shooting are important to study because they are rare events which contain high public concern, are difficult to predict and have been increasing in recent years. This study examined the self-reported motives of nineteen perpetrators of school shootings throughout the world by examining their manifestos and other writings. If no self-reported motives were found then statements made in the perpetrators writings were used to decide what factors may have motivated them to commit their act. In particular, we looked at what motivations the perpetrators expressed in their writings and which motivations …


Blow Fly (Diptera: Calliphoridae) Responses To Different Colors Of Baited Traps, Oluwadamilola Olufunso Oke Jan 2017

Blow Fly (Diptera: Calliphoridae) Responses To Different Colors Of Baited Traps, Oluwadamilola Olufunso Oke

Honors College Theses

Blow flies (Diptera: Calliphoridae) are usually the first insects to colonize human remains. By determining the time of colonization, a postmortem interval (PMI), or “time of death”, can be estimated. To develop more accurate PMI estimates, it is important for forensic entomologists to understand the cues that Blow flies use to locate vertebrate remains. The purpose of this study was to determine whether Blow flies use visual cues, in addition to olfactory cues, to locate carrion. Two colors of fly traps, clear and green, were constructed and chicken gizzard used as bait. Three Blow fly species exhibited a significant preference …


Testing The Optomotor Response In Sepia Bandensis, Lauren E. Thompson Jan 2017

Testing The Optomotor Response In Sepia Bandensis, Lauren E. Thompson

Honors College Theses

Cephalopods (octopus, squid, and cuttlefish) have commonly been used as models to test visual function and camouflage due to their similarity in eye morphology with humans and because of their readily observable changes in body color in response to visual stimuli. Most studies have used a single species, Sepia officinalis, to make broad conclusions about camouflage and vision. However, these generalizations may not be applicable to all species. Here, I have examined visual function of the dwarf cuttlefish (Sepia bandensis), which differs from S. officinalis in habitat, geographic range, and size. Using the optomotor response, I quantified …


Dealing With Students’ Plagiarism Pre-Emptively Through Teaching Proper Information Exploitation, Mariya Chankova Jan 2017

Dealing With Students’ Plagiarism Pre-Emptively Through Teaching Proper Information Exploitation, Mariya Chankova

International Journal for the Scholarship of Teaching & Learning

The present contribution looks into the much discussed issue of student plagiarism, which is conjectured to stem from problems with information searching and exploitation, underdeveloped exposition skills and difficulty in using sources, especially concerning quotations and references. The aim of the study is to determine how effective pre-emptive measures can be if information exploitation and writing from sources are approached as skills that need to be taught. The results show that addressing source use as a skill tends to gradually if slowly reduce the number of plagiarized assignments submitted by students.

College of Graduate Studies: Theses & Dissertations

In an attempt to create more effective chemotherapeutic compounds, the naphthoquinone adduct, 12,13-dihydro-N-methyl-6,11,13-trioxo-5H-benzo[4,5]cyclohepta [1,2 b]naphthalen-5,12-imine (hereafter called TU100) was synthesized. Inspired by its unique and novel mechanism of action, a series of structural derivatives were synthesized to explore structure-activity relationships. The analogues exhibited different cytotoxicity profiles, revealing the indicated regions are involved in cell death induction. Furthermore, the analogues had dramatically different effects on cellular ATP production, suggesting different molecular targets. Synthesis, biological activity, and SAR study of these analogues will be revealed.


Development Of A Molecular Assay For Caribbean Coral Identification, Elijah D. O'Cain Jan 2017

Development Of A Molecular Assay For Caribbean Coral Identification, Elijah D. O'Cain

College of Graduate Studies: Theses & Dissertations

As coral cover has declined throughout the Caribbean, interest in the role that recruitment processes play in reef recovery has increased. Studies investigating these processes have been hampered by the inability to identify many species of coral larvae or recently settled recruits using morphology. In this study, the utility of targeting the non-coding internal transcribed spacer (ITS) regions with a multiplex PCR assay to identify common Caribbean coral species was explored. To design this assay, a database of ITS sequences was developed for 17 Caribbean scleractinian coral species that are important reef builders and/or common in the Florida Keys. It …


Mercury Cycling In Sulfur Rich Sediment From The Brunswick Estuary, Travis William Nicolette Jan 2017

Mercury Cycling In Sulfur Rich Sediment From The Brunswick Estuary, Travis William Nicolette

College of Graduate Studies: Theses & Dissertations

Mercury is potentially toxic to the environment. Mercury is absorbed into anaerobic sediments of surface waters, which may be converted to methylmercury, a toxic form of mercury that bio-accumulates in aquatic biota. Sources of mercury in the environment vary, but the production of methylmercury is common in sulfur-rich sediments containing mercury. In such environments, sulfur reducing bacteria (SRB) produce methylmercury as a by-product. The metabolic process uses energy from the reduction of sulfate to sulfide. This study focuses on determining the methylmercury production and release potential from sulfur-rich sediments extracted from different areas of the Brunswick Estuary. Previous studies note …


Optimization Methods For Tabular Data Protection, Iryna Petrenko Jan 2017

Optimization Methods For Tabular Data Protection, Iryna Petrenko

College of Graduate Studies: Theses & Dissertations

In this thesis we consider a minimum distance Controlled Tabular Adjustment (CTA) model for statistical disclosure limitation (control) of tabular data. The goal of the CTA model is to find the closest safe table to some original tabular data set that contains sensitive information. The measure of closeness is usually measured using l1 or l2 norm; with each measure having its advantages and disadvantages. According to the given norm CTA can be formulated as an optimization problem: Liner Programing (LP) for l1, Quadratic Programing (QP) for l2. In this thesis we present an alternative …


The Effect Of Social Influence On Perception Of Tornado Warnings, Jason A. Parker Jan 2017

The Effect Of Social Influence On Perception Of Tornado Warnings, Jason A. Parker

College of Graduate Studies: Theses & Dissertations

Tornado activity annually results in many deaths throughout the U.S. As a result, the emergency alert system (including tornado warnings) has made considerable advancements throughout the past few decades. However, continued improvements could be made to warning content that aid to facilitate adaptive decision-making by increasing individuals’ motivation to respond. One method that could increase adaptive responses to warnings is by including the modality of descriptive social information within the warning. Research suggests that normative social influence acts as a powerful motivator for individuals to conform toward the witnessed or perceived behaviors of others. The current study examined the impact …


Silver Nanoparticle Fate And Accumulation In The Aquatic Food Web Of Stream Microcosms, Stefan J. Petersen Jan 2017

Silver Nanoparticle Fate And Accumulation In The Aquatic Food Web Of Stream Microcosms, Stefan J. Petersen

College of Graduate Studies: Theses & Dissertations

Silver nanoparticles (AgNPs) are used in 25% of all nano-enabled products and applied for anti-microbial properties. Silver nanoparticles are discharged into aquatic environments through wastewater discharge, runoff, and chemical spills. Once in aquatic environments silver nanoparticles have the potential to harm aquatic organisms. While the fate of silver nanoparticles in lentic systems has been investigated, limited information is available for the fate of silver nanoparticles in flowing environments. The purpose of this study was to compare the fate of AgNPs following a one-time pulsed application simulating a chemical spill, or small repetitive applications simulating effluent discharge, in artificial stream communities …


The Construction Of A Transatlantic Subject: Family And Nation In "Sola" By María José De Chopitea, Valeriya F. Fritz Jan 2017

The Construction Of A Transatlantic Subject: Family And Nation In "Sola" By María José De Chopitea, Valeriya F. Fritz

The Coastal Review

This article explores the articulation of exile identity in the novel Sola by María José de Chopitea published in Mexico in 1954. Until now, critics have approached this text as lacking ideological argument. I propose an alternative reading of the novel as an ideologically charged narrative that articulates the nation beyond state borders and in terms of a transatlantic bond between Mexico and the Spanish Republic. Sola creates space in the nation for Catalan female writers who were previously excluded due to both their gender and their status as political exiles and cultural minorities.


Educación, Escritura Y Memoria: Las Armas De La Alteridad Frente Al Discurso Oficial Y La Desmemoria En "Por El Cielo Y Más Allá", Emilio L. Ramon Jan 2017

Educación, Escritura Y Memoria: Las Armas De La Alteridad Frente Al Discurso Oficial Y La Desmemoria En "Por El Cielo Y Más Allá", Emilio L. Ramon

The Coastal Review

Por el cielo y más allá invites the reader to reflect upon populist discourses paving the way for discrimination and marginalization; especially those aimed at a different gender, ethnic group, national origin or even an academic sub-specialty. Those who were persecuted in the past are now the ones harassing, and use the ambiguity of words as their tool. Words, in turn, enslave but also help set the others free. The memories of those marginalized are perpetuated through education, letters, poems and songs. They oppose the official discourse and invite the reader to avoid monolithic discourses and embrace tolerance and diversity.

AMTP Proceedings 2017

A sample of 205 university students provided input regarding an array of 32 issues germane to both green marketing and green consumption. A diverse array of behaviors and opinions were articulated. Respondents reported a high propensity to engage in recycling, donating used goods, and purchasing products with a longer life expectancy. They favored environmentally-friendly actions such as focusing on cleaner and more efficient energy alternatives. There was a strong belief that individuals can make a difference. A comparison of business and nonbusiness students documented significant differences on two of the 32 issues under investigation with nonbusiness students expressing greater concern …


Treatment Choice Among Combat Veterans, Zachary Clayborne Dietrich Jan 2017

Treatment Choice Among Combat Veterans, Zachary Clayborne Dietrich

College of Graduate Studies: Theses & Dissertations

A plethora of research has investigated PTSD treatment outcomes among Veterans of foreign wars. However, research has suggested mixed treatment efficacy. Although investigations into factors that may help predict treatment outcomes are emerging, to date no study has evaluated treatment choice among Veteran populations. Previous treatment choice studies have yielded qualitative and quantitative information that can be useful in clinical decision-making. This study looks to build upon the treatment choice literature with combat Veterans to evaluate for underlining characteristics of cohorts that will help build upon existing knowledge. It has been suggested that treatment benefits Vietnam Era Veterans more than …

The Effect Of Loving-Kindness Meditation On Physiological And Psychological Reactions To Violent Stimuli, Joseph A. Garcia Jan 2017

The Effect Of Loving-Kindness Meditation On Physiological And Psychological Reactions To Violent Stimuli, Joseph A. Garcia

College of Graduate Studies: Theses & Dissertations

In the past, meditation research has focused primarily on mindfulness meditation, but little research has examined Loving-Kindness Meditation (LKM). LKM may be an important addition to treatment or preventative programs for people at risk of exposure to violence or aggression in their lives or work. The current research aims to add to the currently growing body of literature concerning LKM and compassion based meditation practices. The researchers sought to determine if a 12-week course in LKM would have any effect on galvanic skin response (GSR) and heart rate in beats per minute (BPM) during the presentation of a video containing …


Assessing The Genetic Status And Factors Leading To The Decline Of The Roanoke Bass (Ambloplites Cavifrons), Jackman C. Eschenroeder Jan 2017

Assessing The Genetic Status And Factors Leading To The Decline Of The Roanoke Bass (Ambloplites Cavifrons), Jackman C. Eschenroeder

College of Graduate Studies: Theses & Dissertations

Although numerous factors have led to the staggering declines in freshwater biodiversity throughout the United States and the world, habitat alteration and introduced species pose some of the greatest challenges to conservation efforts. Learning more about how these two factors lead to the decline of an endemic organism could help prevent the future loss of unique species and the premature conclusion of evolutionary trajectories. Roanoke bass (Ambloplites cavifrons) is a sport fish endemic to portions of the Roanoke, Chowan, Tar, and Neuse river basins of North Carolina and Virginia. This species has been in decline for many years, …


Dual Task Testing Of The Adaptive Combination View In Spatial Reorientation, Donald G. Sullens Jan 2017

Dual Task Testing Of The Adaptive Combination View In Spatial Reorientation, Donald G. Sullens

College of Graduate Studies: Theses & Dissertations

If an organism is trained to approach a location within an enclosure the organism will approach the correct location and it’s geometrically identical location within the environment upon removal of any features. This phenomenon has been turned spatial reorientation, and further studies on how, and to what, organisms reorient have conducted in the last several decades. In the reorientation literature, two theories have surfaced to fill the void left by the rejection of the initial reorientation theory, the Geometric Module theory. I attempt look to discern if the synonym judgement dual task will hinder reorientation in a similar or different …


The Effect Of Repetitive Head Impacts On Postural Control Over The Course Of A Single Season, Katelyn E. Grimes Jan 2017

The Effect Of Repetitive Head Impacts On Postural Control Over The Course Of A Single Season, Katelyn E. Grimes

College of Graduate Studies: Theses & Dissertations

INTRODUCTION: Recently neurocognitive dysfunction has been linked to poor postural control in concussed athletes. While the detrimental effect of repetitive head impacts on cognitive function have been shown to mirror the effects of concussive injury, very little research has investigated the physical consequences of repetitive head impacts. PURPOSE: To observe the effects of RHI on postural control, both static and dynamic, in NCAA Division I athletes over the course of a single season. METHODS: 9 NCAA Division I football athletes (CON) were recruited from a single university as the experimental group, as well as 9 NCAA Division I baseball players …

College of Graduate Studies: Theses & Dissertations

Nanotechnology is easily becoming one of the fastest growing markets around the globe. Synthetic nanomaterials have many unique chemical and physical properties, mainly due to their huge specific surface area and chemical makeup. Specifically, titanium dioxide (TiO2) nanomaterials have high stability, anticorrosive and photocatalytic properties. These nanomaterials have applications for semiconductor photocatalysis, treatment of water, as a photoactive material in nanocrystalline solar cells, and medicine. However, not much is known about the toxicity of TiO2 in the nanofiber form. The objective of the present study is to investigate the adverse effects associated with acute ingestion of TiO …


The American Pastoral Tradition And The Stories Of Breece D'J Pancake, Christopher Blackburn Jan 2017

The American Pastoral Tradition And The Stories Of Breece D'J Pancake, Christopher Blackburn

College of Graduate Studies: Theses & Dissertations

In the late twentieth century, Breece Pancake carried on the American pastoral tradition by both featuring and modifying characteristics of early American pastoral literature. Breece Pancake does not directly imitate his predecessors, but instead brings the spirit of the nearly 200-year-old tradition in which he participates to a twentieth-century audience. Part of the enduring relevance of the literature in the American pastoral tradition, including The Stories of Breece D’J Pancake, is that at the heart of these stories is a theme that has defined and continues to shape the American experience: the struggle with living in liminal spaces.


My Life Is A Manifesto: From Rich, To Poor, To Teacher, Angela M. Pieniaszek Jan 2017

My Life Is A Manifesto: From Rich, To Poor, To Teacher, Angela M. Pieniaszek

College of Graduate Studies: Theses & Dissertations

This inquiry travels through stages of my education and life in order to explore the following three questions: How do a teacher’s values and personal experiences translate into teaching lives and teaching acts? How do teachers and students live counterstories inside and outside of the classroom? How do class, gender and place impact teaching and learning? Building on the works of critical theorists, (Apple, 2004; Ayers, 2004; Delpit, 2006; Freire, 2005; hooks, 1994; Kincheloe, 2004; Kincheloe & Pinar, 1991; Kozol, 1992; Watkins, 2001,2004), autobiographical studies (He, 2003, 2010; Miller, 2005; Pinar, 1994; Schubert & Ayers; 1990) and memoirs (Angelou, 1993; …


Examining The Effects Of Enclosure Size At Training And At Test In Spatial Reorientation, Zebulon K. Bell Jan 2017

Examining The Effects Of Enclosure Size At Training And At Test In Spatial Reorientation, Zebulon K. Bell

College of Graduate Studies: Theses & Dissertations

Previous research has begun to shed light on the differentiated influence of enclosure size on cue use during reorientation (Sturz, Forloines, & Bodily, 2012). Namely, the question remains of why both feature (i.e., objects or landmarks in the enclosure) and geometric (i.e., shape of the enclosure) cues are differentially affected by enclosure size, and the extent to which local (i.e., wall lengths and corner angles) and global (i.e., principal axis of space) geometric cues are affected by enclosure size. Further, it remains unclear whether training size, testing size, or the relationship between training and testing size influences the use of …
