Relating Climate Change To The Nesting Phenology And Nest Environment Of Marine Turtles, Monette Schwoerer
Relating Climate Change To The Nesting Phenology And Nest Environment Of Marine Turtles, Monette Schwoerer
Electronic Theses and Dissertations
Ectotherms (including marine turtles) being especially sensitive to climate, are at risk to the accelerated rate of human-driven climate change. This study addresses two concerns associated with marine turtles and climate change – the relationship between the timing of marine turtle nesting and sea surface temperature; and the concern over the feminization of marine turtle populations due to rising sand temperatures. Previous studies of loggerhead sea turtles (Caretta caretta) and green sea turtles (Chelonia mydas) have documented the relationship between sea surface temperatures and nesting phenology. Earlier nesting behaviors in both species have been associated with warmer sea surface temperatures. …
Twentieth Century Maya Worldview, Mackenzie See
Twentieth Century Maya Worldview, Mackenzie See
Electronic Theses and Dissertations
Maya Folktales offer insight into how twentieth century Maya worldview is a hybrid of indigenous Maya and European beliefs. Analysis was conducted on twenty-eight Maya folktales from the highlands of Guatemala found in folklore anthologies. Stories like The Spirits of the Dead in folklore anthologies can reveal new perspectives on how the Maya feel about rituals spaces, the fabric that separates the land of the dead from the land of the living, and the importance of showing respect to the dead in one’s community. Other stories, show the connection the Maya feel with their heritage and the connection they feel …
Juvenile Ornamentation: Its Evolution, Genetic Basis, And Variation Across Habitats, Angela Tringali
Juvenile Ornamentation: Its Evolution, Genetic Basis, And Variation Across Habitats, Angela Tringali
Electronic Theses and Dissertations
Ornamental traits are considered honest advertisements of fitness, and their evolution is usually explained in terms of sexual selection. This explanation remains unsatisfactory in some instances, for example, juvenile birds whose plumage is molted prior to adulthood and breeding. I first evaluate whether juvenile plumage reflectance signals dominance status in the Federally Threatened Florida scrub-jay (Aphelocoma coerulescens) using a combination of observational and experimental methods. Then I estimate the heritability, non-genetic maternal and environmental effects, and strength of selection on juvenile plumage reflectance using archived feather samples and a pedigree constructed from historical nest records. Finally, I compare plumage reflectance …
Which Way To The Jook Joint?: Historical Archaeology Of A Polk County, Florida Turpentine Camp, Deborah Ziel
Which Way To The Jook Joint?: Historical Archaeology Of A Polk County, Florida Turpentine Camp, Deborah Ziel
Electronic Theses and Dissertations
The extraction and distillation of pine sap for the naval stores industry reached its apex of production in the early decades of the twentieth century. Post-emancipation, the industry employed African American labor in the long leaf pine forests of the southeastern United States under a system of debt peonage that replaced the master-slave dynamic with a similar circumscriptive construct. Laborers rented company housing and were paid in scrip, a monetary system that limited their purchase of the basic goods of subsistence to the company commissary at inflated prices, resulting in an endless cycle of debt. Despite the oppressive circumstances of …
Meme World Syndrome: A Critical Discourse Analysis Of The First World Problems And Third World Success Internet Memes, Robert Chandler
Meme World Syndrome: A Critical Discourse Analysis Of The First World Problems And Third World Success Internet Memes, Robert Chandler
Electronic Theses and Dissertations
This thesis applies the theory and method of Critical Discourse Analysis (CDA) to examine the ideological components of the First World Problems (FWP) and Third World Success (TWS) Internet memes. Drawing on analytical concepts from CDA and related perspectives, such as multimodal discourse analysis and social semiotics, the paper analyzes the visual and textual elements of a sample of the FWP and TWS memes. The paper argues that the text and images featured in the memes are ideologically salient and discursively construct oppositional binaries between “us” and “them” in terms of wealth disparity.
Textual Analysis Of The Portrayals Of The Roma In A U.S. Newspaper, Sabrina Deaton
Textual Analysis Of The Portrayals Of The Roma In A U.S. Newspaper, Sabrina Deaton
Electronic Theses and Dissertations
This study examined the media portrayals of Roma in the United States by taking a closer look at ―Gypsy crime‖ articles in a purposive sample of newspaper articles. These newspaper articles give details of ―confidence‖ crimes and name the alleged perpetrators as Roma or members of the ethnic minority group commonly known as Gypsies. A textual analysis was conducted of 23 articles appearing in the South Florida Sun-Sentinel from August 16, 2011 to February 8, 2013 covering fraud charges against several members of the Marks family. This primary evaluation narrowed the initial sample to nine articles that contained references to …
Changes In Neolithic Subsistence Patterns On Flores, Indonesia Inferred By Stable Carbon, Nitrogen, And Oxygen Isotope Analyses Of Sus From Liang Bua, Jordon Munizzi
Electronic Theses and Dissertations
Despite an abundance of archaeological material recovered from sites in Island Southeast Asia, the timing and route by which cultigens first arrived in Wallacea remains unclear. Many of the staple crops now grown on these islands were domesticated in mainland Asia, and were deliberately introduced by humans at an unknown point during the Holocene, through several possible routes. In this study, the δ 13C, δ15N and δ18O values of subfossil bones and teeth attributed to Sus celebensis and Sus scrofa are analyzed. These materials, which span the last 5160 years at Liang Bua, Flores, Indonesia are used to determine if …
Modeling Survival Of Immature Loggerheads (Caretta Caretta) And Green Turtles (Chelonia Mydas) From 10 Years Of Mark-Recapture Data At The Florida Power And Light St. Lucie Plant, Andrew Sterner
Electronic Theses and Dissertations
Loggerheads (Caretta caretta) are listed as Threatened and green turtles (Chelonia mydas) are listed as Endangered under the United States Endangered Species Act. While green turtle nest production in Florida has increased markedly in recent years, loggerhead nest production has followed a more tenuous path. Reasons for these differences are unknown. Limited demographic information is available for these species of conservation concern. I used Barker models, which incorporated mark-recapture, live-resight and dead recovery data, implemented in Program MARK. These models were used to estimate apparent survival for immature loggerhead (
Imperial Japan's Human Experiments Before And During World War Two, Alan Vanderbrook
Imperial Japan's Human Experiments Before And During World War Two, Alan Vanderbrook
Electronic Theses and Dissertations
After Japan occupied Manchuria in 1931, Ishii Shiro created Unit 731 and began testing biological weapons on unwilling human test subjects. The history of Imperial Japan’s human experiments was one in which Ishii and Unit 731 was the principal actor, but Unit 731 operated in a much larger context. The network in which 731 operated consisted of Unit 731 and all its sub-units, nearly every major Japanese university, as well as many people in Japan’s scientific and medical community, military hospitals, military and civilian laboratories, and the Japanese military as a whole. Japan’s racist ultra-nationalist movement heavily influenced these institutions …
Virtual Coaching Of Novice Science Educators To Support Students With Emotional And Behavioral Disorders, Dennis Garland
Virtual Coaching Of Novice Science Educators To Support Students With Emotional And Behavioral Disorders, Dennis Garland
Electronic Theses and Dissertations
Due to a multitude of convergent circumstances, students labeled in the disability category of emotional and behavioral disorders (EBD) experience high rates of academic and behavioral failure. Such failure frequently leads to the students’ dropping out of school, involvement in the judicial system, or a combination of those outcomes. Science is an academic content area that has the potential to enhance behavioral and academic success of students with EBD. Researchers, nonprofits, and business leaders have provided an impetus for nationwide reform in science education. Concurrently, a corpus of legislation has influenced the preparation of new teachers to use evidence-based teaching …
The Politics Of The Righteous: A Religious And Political History Of Conservative Neo-Evangelicals In Central Florida, Rustin Lloyd
The Politics Of The Righteous: A Religious And Political History Of Conservative Neo-Evangelicals In Central Florida, Rustin Lloyd
Electronic Theses and Dissertations
In 1953 a small, seemingly insignificant, church was founded in Winter Park, Florida. By the early 1970s, Calvary Assembly of God, a church that had started with a dirt floor, was declared one of the fastest growing churches in America with membership easily reaching over several thousands.1 In the late 1970s and 1980s, it became a major religious and political force in central Florida so much so that it had received visits from then presidential hopefuls Pat Robertson and Vice President George Bush. The changes that took place at Calvary Assembly, both politically and religiously, provided a microcosm of the …
Disturbance-Based Management And Plant Species Change In Massachusetts Sandplain Heathlands Over The Past Two Decades, Kirsten Martin
Disturbance-Based Management And Plant Species Change In Massachusetts Sandplain Heathlands Over The Past Two Decades, Kirsten Martin
Electronic Theses and Dissertations
Massachusetts sandplain heathlands are habitats of conservation concern, harboring many rare plant species and providing habitat for animals that depend on openlands. These heathlands are threatened by human development, shrub encroachment in the absence of disturbance, and potentially increasing soil nutrient levels. Sandplain heathlands are managed with prescribed fire, in order to maintain their open structure and maintain species diversity. In order to assess how past management was correlated with species change, I used a data set that spanned twenty years from three different heathlands in Massachusetts. I looked for correlations between management and species change. Correlations between species change …
The Contribution Of Visceral Fat To Positive Insulin Signaling In Ames Dwarf Mice, Vinal Menon
The Contribution Of Visceral Fat To Positive Insulin Signaling In Ames Dwarf Mice, Vinal Menon
Electronic Theses and Dissertations
Ames dwarf (df/df) mice are homozygous for a spontaneous mutation in the prop1 gene due to which there is no development of anterior pituitary cells – somatotrophs, lactotrophs and thyrotrophs, leading to a deficiency of growth hormone (GH), prolactin (PRL) and thyrotropin (TSH). They tend to become obese as they age, but still live longer and healthier lives compared to their wild-type littermates, being very insulin sensitive, showing no signs of diabetes and cancer. These mutant mice also have high circulating levels of anti-inflammatory and antidiabetic adiponectin. Plasma levels of this adipokine usually decrease with an increase in accumulation of …
The Perception And Measurement Of Human-Robot Trust, Kristin Schaefer
The Perception And Measurement Of Human-Robot Trust, Kristin Schaefer
Electronic Theses and Dissertations
As robots penetrate further into the everyday environments, trust in these robots becomes a crucial issue. The purpose of this work was to create and validate a reliable scale that could measure changes in an individual’s trust in a robot. Assessment of current trust theory identified measurable antecedents specific to the human, the robot, and the environment. Six experiments subsumed the development of the 40 item trust scale. Scale development included the creation of a 172 item pool. Two experiments identified the robot features and perceived functional characteristics that were related to the classification of a machine as a robot …
The Moral Oppression Of The Teaching Profession: Learning To Transcend, Rebecca Smith
The Moral Oppression Of The Teaching Profession: Learning To Transcend, Rebecca Smith
Electronic Theses and Dissertations
This thesis is both descriptive and philosophical, and at its core, it justifies the need for social foundations of education courses and programs in the university setting. It begins by analyzing the meaning of oppression and the part knowledge plays in confining the individual. The analysis then draws upon Patricia Hill Collins' theory of intersecting oppressions to get at the complexities and restrictions of working in the public schooling institution. It works through the ways in which sexist, classist, and racist practices afflict everyone in the institution through the bureaucratic mechanism and collateral oppression. The four components that make up …
Investigation Of A Novel Magnesium And Acidified Ethanol System For The Degradation Of Persistent Organic Pollutants, Phillip Maloney
Investigation Of A Novel Magnesium And Acidified Ethanol System For The Degradation Of Persistent Organic Pollutants, Phillip Maloney
Electronic Theses and Dissertations
For centuries chemists have sought to improve humankind’s quality of life and address many of society’s most pressing needs through the development of chemical processes and synthesis of new compounds, often with phenomenal results. Unfortunately, there also are many examples where these chemicals have had unintended, detrimental consequences that are not apparent until years or decades after their initial use. There are numerous halogenated molecules in this category that are globally dispersed, resistant to natural degradation processes, bioaccumulative, and toxic to living organisms. Chemicals such as these are classified as persistent organic pollutants (POPs), and due to their negative environmental …
Cerium Oxide Nanoparticles Sensitize Pancreatic Cancer Cells To Radiation By Promoting Acidic Ph, Ros, And Jnk Dependent Apoptosis, Melissa Wason
Cerium Oxide Nanoparticles Sensitize Pancreatic Cancer Cells To Radiation By Promoting Acidic Ph, Ros, And Jnk Dependent Apoptosis, Melissa Wason
Electronic Theses and Dissertations
Side effects of radiation therapy (RT) remain the most challenging issue for pancreatic cancer treatment. In this report we determined whether and how cerium oxide nanoparticles (CONPs) sensitize pancreatic cancer cells to RT. CONP pretreatment enhanced radiation-induced reactive oxygen species (ROS) production preferentially in acidic cell-free solutions as well as acidic human pancreatic cancer cells. In acidic environments, CONPs favor the scavenging of superoxide radical over the hydroxyl peroxide resulting in accumulation of the latter whereas in neutral pH CONPs scavenge both. CONP treatment prior to RT markedly potentiated the cancer cell apoptosis both in culture and in tumors and …
Stereotypes, Perceptions Of Similarity, And Cultural Identity: Factors That May Influence The Academic Achievement Of Immigrant Students., Tamara Fagan
Electronic Theses and Dissertations
For decades, the United States has been known as the nation of immigrants due to the increasing number of immigrant students in the public school system. Although the population of immigrant students steadily increases annually, American society still pressures immigrants into acculturation to fulfill the United States ideals of academic achievement despite the United States claim of multiculturalism (Malcolm & Lowery, 2011). This research focuses on 1st - and 2nd generation immigrant students’ strife of acceptance in U.S. culture, while sill preserving their own native culture, and the influence it has on academic achievement. The researcher interviewed eight (8) adult …
Interpreting Diet And Nutritional Stress In Napoleon's Grand Army Using Stable Carbon And Nitrogen Isotope Analysis, Sammantha Holder
Interpreting Diet And Nutritional Stress In Napoleon's Grand Army Using Stable Carbon And Nitrogen Isotope Analysis, Sammantha Holder
Electronic Theses and Dissertations
A mass grave containing the remains of at least 3269 Napoleonic soldiers from 1812 was discovered in Vilnius, Lithuania in 2001. Stable carbon and nitrogen isotopic analyses were performed on collagen from 78 femoral samples to explore dietary variation within the sample. Starvation and nutritional distress were also evaluated through the examination of nitrogen enrichment in bone collagen. Clinical studies have demonstrated that enriched nitrogen isotope values can indicate periods of nutritional stress and starvation; however, this is the first study to examine its use as a diagnostic indicator of starvation in a historical population using bone tissue. According to …
Wetland Diversity In A Disturbance-Maintained Landscape: Effects Of Fire And A Fire Surrogate On Aquatic Amphibian Survival And Species Depauperateness., Joyce Klaus
Electronic Theses and Dissertations
Disturbance is one of the central concepts explaining how diversity arises and is perpetuated in ecological time. A good model system for testing hypotheses related to disturbance is the longleaf pine ecosystem in the southeastern U.S. because in this ecosystem frequent, low-severity fires acts as a disturbance that maintains a unique vegetation structure and high species richness. Vegetation structure influences animal distributions; in fire-dependent ecosystems many animals rely on open-structured, fire-maintained vegetation but shrubs and trees encroach into fire-dependent ecosystems where fire has been excluded. Prescribed burning and mechanical removal are commonly used as restoration tools to control encroachment. To …
Gender Differences And Fast Food Preferences Among U.S. College Students, Donald Persaud
Gender Differences And Fast Food Preferences Among U.S. College Students, Donald Persaud
Electronic Theses and Dissertations
The intent of this research is to examine the relationship of corporate fast food and health within the context of gender. It tests the hypothesis that Western perceptions of masculinity and femininity inform a differentiated pattern of food preference, which will correlate with health as measured by Body Mass Index (BMI). The targeted sample population for the study is the undergraduate community of the University of Central Florida, and fast food is a chosen dietary medium because it is an increasingly ubiquitous source of caloric energy in the American foodscape, representative of the mass production model applied to cuisine in …
The Effects Of Diagnostic Aiding On Situation Awareness Under Robot Unreliability, David Schuster
The Effects Of Diagnostic Aiding On Situation Awareness Under Robot Unreliability, David Schuster
Electronic Theses and Dissertations
In highly autonomous robotic systems, human operators are able to attend to their own, separate tasks, but robots still need occasional human intervention. In this scenario, it may be difficult for human operators to determine the status of the system and environment when called upon to aid the robot. The resulting lack of situation awareness (SA) is a problem common to other automated systems, and it can lead to poor performance and compromised safety. Existing research on this problem suggested that reliable automation of information processing, called diagnostic aiding, leads to better operator SA. The effects of unreliable diagnostic aiding, …
Biogeography And Systematics Of The Nerodia Clarkii/Nerodia Fasciata Clade In Florida, Gregory Territo
Biogeography And Systematics Of The Nerodia Clarkii/Nerodia Fasciata Clade In Florida, Gregory Territo
Electronic Theses and Dissertations
Biogeography provides a window into the evolutionary history of populations, and helps explain the diversity and distribution of life through time. Viewed from a systematic perspective, biogeographic studies generate convincing arguments to explain the relationships among organisms and categorize them into useful taxonomies. When taxonomies do not reflect evolutionary histories, inaccurate representations of biodiversity confound future studies and conservation efforts. Two thamnophiine snakes, Nerodia clarkii and Nerodia fasciata, harbor unique morphological and ecological adaptations that obscured natural groupings, leading to controversial taxonomic delimitations. Additionally, population declines documented in N. clarkii compressicauda and N. clarkii taeniata led managers to list N. …
Estimated Diets, Diet Overlap, And Winter Habitat Associations Of Four Grassland Sparrows In Florida Dry Prairie, Marianne Korosy
Estimated Diets, Diet Overlap, And Winter Habitat Associations Of Four Grassland Sparrows In Florida Dry Prairie, Marianne Korosy
Electronic Theses and Dissertations
North American grassland birds show long-term population declines that generally exceed the declines of other bird groups. Efforts to conserve grassland birds require knowledge of diet and habitat requirements during both the breeding and nonbreeding periods of annual life cycles. This dissertation investigated sparrow habitat associations within two defined plant communities of the dry prairie ecosystem, the dry-mesic and wet-mesic prairie, for four prescribed fire treatments over two consecutive winters. Grasshopper and Henslow’s sparrows showed higher relative abundance in wet-mesic prairie and Bachman’s Sparrows were more abundant in dry-mesic prairie across all fire treatments. Abundances of Grasshopper and Bachman’s sparrows …
The Role Of Mitochondrial Omi/Htra2 Protease In Protein Quality Control And Mitophagy, Camilla Ambivero
The Role Of Mitochondrial Omi/Htra2 Protease In Protein Quality Control And Mitophagy, Camilla Ambivero
Electronic Theses and Dissertations
Omi/HtrA2 is a mitochondrial serine protease with a dual and opposite function depending on its subcellular localization. Most of the previous studies focused on Omi/HtrA2’s pro-apoptotic function when the protein is released to the cytoplasm. It is becoming apparent that the main function of Omi/HtrA2 is within the mitochondria, where it has a pro-survival role. However, its mechanism is still poorly understood. To this end, we used the yeast two-hybrid system to dissect the Omi/HtrA2 pathway by identifying novel interactors and substrates. Our studies revealed a novel function of Omi/HtrA2 in the regulation of a deubiquitinating (DUB) complex. In addition …
Characterization Of Motility Alterations Caused By The Impairment Of Dynein/Dynactin Motor Protein Complex, Swaran Nandini
Characterization Of Motility Alterations Caused By The Impairment Of Dynein/Dynactin Motor Protein Complex, Swaran Nandini
Electronic Theses and Dissertations
Transport of intracellular cargo is an important and dynamic process required for cell maintenance and survival. Dynein is the motor protein that carries organelles and vesicles from the cell periphery to the cell center along the microtubule network. Dynactin is a protein that activates dynein for this transport process. Together, dynein and dynactin forms a motor protein complex that is essential for transport processes in all the vertebrate cells. Using fluorescent microscope based live cell imaging techniques and kymograph analyses, I studied dynein/dynactin disruptions on the intracellular transport in two different cell systems. In one set of experiments, effects of …
Remediation Of Polychlorinated Biphenyl (Pcb) Contaminated Building Materials Using Non-Metal And Activated Metal Treatment Systems, Tamra Legron-Rodriguez
Remediation Of Polychlorinated Biphenyl (Pcb) Contaminated Building Materials Using Non-Metal And Activated Metal Treatment Systems, Tamra Legron-Rodriguez
Electronic Theses and Dissertations
PCBs are recalcitrant compounds of no known natural origin that persist in the environment despite their ban by the United States Environmental Protection Agency in 1979 due to negative health effects. Transport of PCBs from elastic sealants into concrete, brick, and granite structures has resulted in the need for a technology capable of removing these PCBs from the materials. This research investigated the use of a nonmetal treatment system (NMTS) and an activated metal treatment system (AMTS) for the remediation and degradation of PCBs from concrete, brick, and granite affixed with PCB-laden caulking. The adsorption of PCBs onto the components …
Terrorism: The Effect Of Positive Social Sanctions, Curtis Hibbert
Terrorism: The Effect Of Positive Social Sanctions, Curtis Hibbert
Electronic Theses and Dissertations
Research shows that relative deprivation, mental illness, culture, ideology, and various forms of social learning are often identified as factors that can lead an individual to terrorism. However, understanding the value of influences in the form of positive social sanctions through social contact has not been fully explored throughout terrorist studies. In regards to influencing behavior, positive social sanctions elicit a desired behavior which is reinforced through praise or rewards. By utilizing a case study approach, this thesis looks to determine the significance of positive social sanctions through social contact on select individuals who have committed an act of terror …
Dangerous Instincts, Kirsten Holt
Dangerous Instincts, Kirsten Holt
Electronic Theses and Dissertations
Dangerous Instincts is a collection of poems unified thematically by recurring and interstitial questions of the wilderness, the natural sciences - particularly astrophysics - the occult, and the mythic universe. These poems explore the mystical implications of the natural world and its meaning in the aesthetic consciousness, particularly in a highly secular century. Implied is the poet’s selfdiscovery and search for the divine. The collection emerges, not simply as interpretation, but a means of coming to terms with the fear of and compulsion to question the universe, and through those questions find illumination in the ordinariness of lived life and …
Zora, Genevieve Tyrrell
Zora, Genevieve Tyrrell
Electronic Theses and Dissertations
This mixed-media memoir uses a variety of forms from short epigrammatic essays to straightforward stories and graphic narratives to explore the author’s coming-of-age experiences augmented by chronic illness. Trying to succeed in the film industry, romance, and family situations, the young female narrator navigates the often unexpected or disappointing consequences of having an autonomic nervous system disorder. Relationships between conflicting identities emerge—between healthy versus sick self, projected/envisioned versus actual self, and tough versus vulnerable self—as the narrator journeys toward a more complete and accepting self-understanding.
