Vulture Scavenging Of Child-Sized Pig Carcasses In Central Florida: Utilizing Gis To Analyze Site Variables Affecting Skeletal Dispersal, Alexander Mitchell
Electronic Theses and Dissertations
Scavengers can significantly alter a forensic scene and consume, modify, disarticulate, and disperse bodies. However, little research exists regarding scavenging in Central Florida, specifically scavenging involving Black and Turkey Vultures (Coragyps atratus, Cathartes aura respectively). The purpose of this study is to examine the effects of vulture scavenging on consumption, disarticulation, and dispersal of child-sized carcasses in the Central Florida region. The research sample consisted of four pig (Sus scrofa) carcasses weighing approximately 25kgs that were deposited in two distinct sites (shaded and unshaded) at the Deep Foundations Geotechnical Research Site located on the UCF campus. Two field cameras were …
Role Of Sleep In Exposure Therapy For Posttraumatic Stress Disorder In Oif/Oef Combat Veterans, Franklin Mesa
Role Of Sleep In Exposure Therapy For Posttraumatic Stress Disorder In Oif/Oef Combat Veterans, Franklin Mesa
Electronic Theses and Dissertations
Exposure therapy is theorized to reduce posttraumatic stress disorder (PTSD) symptomatology by promoting habituation/extinction of fear responses to trauma-related cues. Empirical evidence indicates that emotional memory, including habituation/extinction learning, is enhanced by sleep. However, service members with combat-related PTSD often report disturbed sleep. In this study, quality of sleep and indicators of extinction learning were examined in veterans of recent wars who had completed an exposure-based PTSD intervention. Fifty-five participants were categorized into two groups based on self-reported quality of sleep: low sleep disruption severity (LSDS; N = 29) and high sleep disruption severity (HSDS; N = 26). Participants in …
Bmp-7 Inhibits P38 And Jnk Pathways And Increases M2 Macrophage Differentiation To Reduce Atherosclerosis In Apolipoprotein E-/- Mice, Heidi Shoulders
Bmp-7 Inhibits P38 And Jnk Pathways And Increases M2 Macrophage Differentiation To Reduce Atherosclerosis In Apolipoprotein E-/- Mice, Heidi Shoulders
Electronic Theses and Dissertations
We have previously shown that treating atherosclerosis with bone morphogenetic protein-7 (BMP-7) affects the presence of macrophage subtypes in vitro, however it remains unknown whether BMP-7 treatment affects development and progression of atherosclerosis in vivo at an early and mid-stage of the disease. We therefore performed a Day 5 (D5) and Day 28 (D28) study to examine BMP-7's potential to affect monocyte differentiation. Atherosclerotic plaque formation was developed using our standard method and ApoE-/- mice were sacrificed at D5 and D28 post-surgery. Treatment animals received intravenous injections of BMP-7 at 200µg/kg of bodyweight. Hematoxylin and Eosin morphological stain shows that …

Nightgaze: A Microbudget Visual Mixtape, Maillim Santiago
Electronic Theses and Dissertations
Nightgaze is a feature length visual mixtape created by May Santiago to fulfill the Masters of Fine Arts program at UCF. The mixtape is a study of autobigraphical depression in metaphorical visual tracks. Originally conceived as an experimental narrative, it has evolved into a form of essayistic distance within a narrative framework with experimental deviations. This thesis tracks the project from its original conception, through the pre-production, production, and post-production processes. It also formulates a plan for marketing and distributing the project.
Improved Interpolation In Sph In Cases Of Less Smooth Flow, Oddny Brun
Improved Interpolation In Sph In Cases Of Less Smooth Flow, Oddny Brun
Electronic Theses and Dissertations
We introduced a method presented in Information Field Theory (IFT) [Abramovich et al., 2007] to improve interpolation in Smoothed Particle Hydrodynamics (SPH) in cases of less smooth flow. The method makes use of wavelet theory combined with B-splines for interpolation. The idea is to identify any jumps a function may have and then reconstruct the smoother segments between the jumps. The results of our work demonstrated superior capability when compared to a particular challenging SPH application, to better conserve jumps and more accurately interpolate the smoother segments of the function. The results of our work also demonstrated increased computational efficiency …

From Pet To Pest? The Potential Global Range And Food Web Effects Of A Generalist Carnivore, Hannah Bevan
From Pet To Pest? The Potential Global Range And Food Web Effects Of A Generalist Carnivore, Hannah Bevan
Electronic Theses and Dissertations
The Nile monitor lizard [Varanus niloticus (Linnaeus, 1766)] is a generalist carnivore, native to Sub-Saharan Africa and the Nile River but now established in North America as a result of the pet trade. Once introduced, they are a potential invasive threat to native wildlife. Here, I create ensemble species distribution models (SDMs) to predict the global distribution of this generalist carnivore given current and future climate conditions. I then quantify the monitor's potential effects on 85 food webs representing >900 different species within the projected regions based on stomach content data. Climate, vegetation, and elevation data are used for 507 …

To thoroughly analyze Muslim soldiers' attitudes, the thesis explores the total experience of Muslim military service through the Soviet Union's and Red Army's policies toward Muslims and how Russian soldiers viewed their Muslim counterparts. To achieve this, the thesis summarized current scholarship on Soviet and Red Army policies toward Muslims. The thesis analyzed the oral histories and written accounts of Muslim soldiers and Russian soldiers to understand the perceptions of Russians and Muslim soldiers. A hierarchy of cultural backwardness underlined Soviet policies in …
The Russian Connection: How Russia Became A Leader In The World's Human Trafficking Market, Anthony De Mauro
The Russian Connection: How Russia Became A Leader In The World's Human Trafficking Market, Anthony De Mauro
Electronic Theses and Dissertations
This thesis assesses how the history of the USSR and its collapse affected the human trafficking market. By conducting a historical analysis of the Soviet Union, key aspects of Soviet society were determined that allowed for the human trafficking market to establish and operate extremely lucratively; a focus on some of the established factors of human trafficking including corruption, law enforcement, the economy, organized crime, and the dissolution of the Soviet government. While this thesis highlights the historical factors of Russian human trafficking, this thesis does not determine why human trafficking exists beyond the surface exploitation that human trafficking consists …
The Longitudinal Relationship Between Moderate Alcohol Use And Cognitive Aging Among Older Adults., Danielle Herring
The Longitudinal Relationship Between Moderate Alcohol Use And Cognitive Aging Among Older Adults., Danielle Herring
Electronic Theses and Dissertations
Cognitive aging appears inconsistent across cognitive domains, indicating that domains may not all decline at the same rate across individuals. Individual trajectories of cognitive aging can vary widely and are affected by numerous lifestyle and health factors. Alcohol use among older adults is known to confer both health risks, typically related to excessive use, and protective effects, often associated with moderate consumption. Moderate alcohol use has been linked with better cognitive functioning as well as a decrease in cardiovascular mortality and systemic inflammation, as compared to heavy or abstinent users. Given that extant research has identified C-reactive protein (CRP) as …
Neurological Profile Of Older Apoe-Pon1 Double Knockout Mice, Connie Mitra
Neurological Profile Of Older Apoe-Pon1 Double Knockout Mice, Connie Mitra
Electronic Theses and Dissertations
Atherosclerosis is a cardiovascular disease where plaques made up of lipids in the form of cholesterol ester build up in the carotid and innominate arteries that supply blood to the brain. Accumulation of the plaques limit the flow of blood and nutrients to the brain, leading to diminished oxygen supply, increased oxidative stress and cell death. All these have been implicated in Alzheimer's disease (AD). Alzheimer's disease, a chronic, progressive, age related neurodegenerative disorder is the most common form of dementia in the elderly accounting for 60-80% of the cases. Clinically, Alzheimer's disease is characterized by loss of memory, damage …
Diet And Migration In Coastal Oaxaca: Identifying Effects Of Political And Social Collapse Through The Utilization Of Stable Isotope Analysis, Jacklyn Rumberger
Diet And Migration In Coastal Oaxaca: Identifying Effects Of Political And Social Collapse Through The Utilization Of Stable Isotope Analysis, Jacklyn Rumberger
Electronic Theses and Dissertations
This study involves the investigation of diet and mobility among people living in the lower Río Verde Valley, Oaxaca, Mexico, during the Late Classic (AD 500-800) and Early Postclassic (AD 800-1200) periods. Specifically, this research focuses on how political and social collapse affected subsistence practices and diet, particularly maize agriculture and consumption, as well as human migration. Archaeological evidence suggests that Río Viejo, the region's largest urban center before AD 800, experienced multiple periods of political fragmentation and instability during its long history, specifically during the Early Classic (AD 250 - 500) and Early Postclassic periods, making it an ideal …
Role Of Kruppel-Like Factor 8 (Klf8) In Cancer And Cardiomyopathy, Satadru Lahiri
Role Of Kruppel-Like Factor 8 (Klf8) In Cancer And Cardiomyopathy, Satadru Lahiri
Electronic Theses and Dissertations
Cancer and cardiovascular diseases are two most fatal diseases causing innumerable death each year. Understanding the mechanisms underlying these diseases is critical for developing proper therapeutic approach. Kruppel-like factor 8 (KLF8) is a member of Kruppel-like family transcription factors that is overexpressed in many types of cancers. There is no report on role of KLF8 in cardiovascular diseases to date. KLF8 transcriptionally activates or represses a host of target genes to promote cancer cell proliferation, migration, invasion and epithelial to mesenchymal transition during tumor progression. Studies proposed in this thesis identified a novel posttranslational modification of KLF8 essential for its …
Multidimensional Room-Temperature Fluorescence Microscopy For The Nondestructive Analysis Of Forensic Trace Textile Fibers, Nirvani Mujumdar
Multidimensional Room-Temperature Fluorescence Microscopy For The Nondestructive Analysis Of Forensic Trace Textile Fibers, Nirvani Mujumdar
Electronic Theses and Dissertations
The purpose of this dissertation is to advance nondestructive methodology for forensic fiber examination. Non-destructive techniques that can either discriminate between similar fibers or match a known to a questioned fiber – and still preserve the physical integrity of the fibers for further court examination - are highly valuable in forensic science. A challenging aspect of forensic fiber examinations involves the comparison of fibers colored with visually indistinguishable dyestuffs. This is not an uncommon situation, as there are numerous indistinguishable fibers pre-dyed with commercial dyes of virtually identical colors. Minimal chemical structural variations are actually encouraged by the dye patent …
Individual Differences In Trust Toward Robotic Assistants, Tracy Sanders
Individual Differences In Trust Toward Robotic Assistants, Tracy Sanders
Electronic Theses and Dissertations
This work on trust in human-robot interaction describes a series of three experiments from which a series of predictive models are developed. Previous work in trust and robotics has examined HRI components related to robots extensively, but there has been little research to quantify the influence of individual differences in trust on HRI. The present work seeks to fill that void by measuring individual differences across a variety of conditions, including differences in robot characteristics and environments. The models produced indicate that the main individual factors predicting trust in robotics include pre-existing attitudes towards robots, interpersonal trust, and personality traits.
The Mauc Gene Encodes A Versatile Signal Sequence And Redox Protein That Can Be Utilized In Native And Non-Native Protein Expression And Electron Trnasfer Systems, Brian Dow
Electronic Theses and Dissertations
The redox-active type 1 copper site of amicyanin is composed of a single copper ion that is coordinated by two histidines, a methionine, and a cysteine residue. This redox site has a potential of +265 mV at pH7.5. Over ten angstroms away from the copper site resides a tryptophan residue whose fluorescence is quenched by the copper. The effects of the tryptophan on the electron transfer (ET) properties were investigated by site-directed mutagenesis. Lessons learned about the hydrogen bonding network of amicyanin from the aforementioned study were attempted to be used as a model to increase the stability of another …
Pyroglutamylated Amyloid Beta Peptides Enhance Non-Fibrillogenic Aggregation Of The Unmodified Peptide, Gregory Goldblatt
Pyroglutamylated Amyloid Beta Peptides Enhance Non-Fibrillogenic Aggregation Of The Unmodified Peptide, Gregory Goldblatt
Electronic Theses and Dissertations
Alzheimer's disease (AD) is accompanied by abnormal extracellular deposition of amyloid b (Ab) peptide. This has led to the amyloid cascade hypothesis, causatively relating Ab with AD. While Ab deposits assume a fibrillar cross-b structure, prefibrillar oligomers of Ab have been identified as the main cytotoxic agents in AD. Pyroglutamylated amyloid beta (AbpE) peptides are N-terminally truncated and pyroglutamylated (at Glu3 or Glu11) Ab molecules that display enhanced cytotoxicity and represent up to 50% of total Ab in AD brains. AbpE significantly enhances the toxicity of unmodified Ab by an unknown mechanism. Although in situ Ab populations are heterogeneous, the …

Supporting Situation Awareness Through Robot-To-Human Information Exchanges Under Conditions Of Visuospatial Perspective Taking, Elizabeth Phillips
Electronic Theses and Dissertations
The future vision of military Soldier—robot teams is one in which Soldiers and robots work together to complete separate, but interdependent tasks that advance the goals of the mission. However, in the near term, robots will be limited in their ability to successfully perform tasks without, at least, occasional assistance from their human teammates. A need exists to design, in robots, mechanisms that can support human situation awareness (SA) regarding the operations of the robot, which humans can use to provide interventions in robot tasks. The purpose of the current study was to test the effects of information exchanges provided …
From The Yellow Peril To The Model Minority: An Experimental Survey Examining Racial Attitudes Towards Asian Americans, Jenny Nguyen
From The Yellow Peril To The Model Minority: An Experimental Survey Examining Racial Attitudes Towards Asian Americans, Jenny Nguyen
Electronic Theses and Dissertations
Attitudinal research continues to show a more liberal trend in racial attitudes of Whites towards Blacks across a spectrum of issues (i.e. interracial marriage, residential integration, etc.) leading some to believe that we are moving into a post-racial society. However, a growing body of research has brought into question this utopian post-racial assertion. While Whites express support for racial equality in principle, they vehemently oppose race-targeted policies aimed to address racial inequality. This principle-policy gap has been consistently associated with persistent racial resentment; thus, contradicting the notion that of a post-racial era. Existing attitudinal research is often limited to the …

Role Of Klf8-Cxcr4 Signaling In Breast Cancer Metastasis, Debarati Mukherjee
Role Of Klf8-Cxcr4 Signaling In Breast Cancer Metastasis, Debarati Mukherjee
Electronic Theses and Dissertations
Krüppel-like factor 8 (KLF8) has been strongly implicated in breast cancer metastasis. However, the underlying mechanisms remain largely unknown. In this study we report a novel signaling from KLF8 to C-X-C cytokine receptor type 4 (CXCR4) in breast cancer. Overexpression of KLF8 in MCF-10A cells induced CXCR4 expression at both mRNA and protein levels. This induction was well correlated with increased Boyden chamber migration, matrigel invasion and transendothelial migration (TEM) of the cells towards the ligand CXCL12. On the other hand, knockdown of KLF8 in MDA-MB-231 cells reduced CXCR4 expression associated with decreased cell migration, invasion and TEM towards CXCL12. …
Resistance Exercise Elicits Selective Mobilization And Adhesion Characteristics Of Granulocytes And Monocyte Subsets, Adam Jajtner
Resistance Exercise Elicits Selective Mobilization And Adhesion Characteristics Of Granulocytes And Monocyte Subsets, Adam Jajtner
Electronic Theses and Dissertations
Resistance exercise eliciting muscle damage results in an immune response, leading to increases in circulating cytokines, and immune cell mobilization. Classical monocytes respond to muscle damage, however, little is known about the intermediate or nonclassical monocyte response to resistance exercise. Moreover, the impact of polyphenol supplementation in conjunction with resistance exercise on the innate immune response is unknown. The purpose of this study was to examine the immune response following resistance exercise with (PPB) and without (PL) polyphenol supplementation. Thirty-nine untrained men were randomized into three groups: PPB (n=13, 21.8±2.5yrs, 171.2±5.5cm, 71.2±8.2kg), PL (n=15, 21.6±2.5yrs, 176.5±4.9cm, 84.0±15.7kg) or a control …

Though I Know The River Is Dry, Victoria Campbell
Electronic Theses and Dissertations
Though I Know the River is Dry is a place-oriented collection of short fiction. The included stories follow female protagonists as they struggle with identity, relationships, and place in the world. The women in these stories frequently grapple with the fear of being loved in the wrong way, often unearthing a deeper examination of what it means to be tethered to a person or a place, along with the ramifications of these ties. All tangentially related to the island of Martha's Vineyard, place serves as a grounding element in this collection, as well as an entity with which the women …
Kidron Road And Other Stories, Jason Molohon
Kidron Road And Other Stories, Jason Molohon
Electronic Theses and Dissertations
Kidron Road and Other Stories is a collection of fiction that ranges from the soberly tragic to the magically real. The characters in each selection are molded by their choices, the choices of others, and the cruel whims of fate. I am fascinated by the way fatalism and free will intersect in the human experience. Therefore, my work often explores the paradoxical way lives are molded by past decisions while, at the same time, those decisions seem determined by outside forces.
Reconstructing Pregnancy, Sarudzayi M. Matambanadzo
Reconstructing Pregnancy, Sarudzayi M. Matambanadzo
SMU Law Review
Congress passed the Pregnancy Discrimination Act in 1978 to amend Title VII’s prohibition against sex discrimination to include discrimination on the basis of pregnancy, childbirth, and related medical conditions. More than thirty-five years after the passage of the Pregnancy Discrimination Act, courts have failed to fulfill its promise. This failure lies, in part, from a tendency to reduce pregnancy, with all of its social and cultural meaning, to its “purely” biological elements. For the purposes of the Pregnancy Discrimination Act, courts ground the legal conception of pregnancy in a form of biomedical essentialism that treats pregnancy as a universal given. …
Airborne Assassin: Why The Official Stockpiles Of The Smallpox Virus Must Be Destroyed, Kylie Thompson
Airborne Assassin: Why The Official Stockpiles Of The Smallpox Virus Must Be Destroyed, Kylie Thompson
Emory International Law Review
In 1980, after a successful immunization campaign, WHO declared that smallpox, a virus that ravaged the human race, was eradicated. Today, the smallpox virus officially exists within two government laboratories: the CDC and Vector. The issue of whether or not to destroy the official stockpiles of the smallpox virus has been vigorously debated. Recent incidents, such as protocol lapses and the discovery of a forgotten stockpile, have further pushed the issue. In an increasingly interconnected world, the outbreak of a highly contagious, eradicated disease is more than disconcerting. The threat of bioterrorism also cannot be ignored as smallpox has been …
Why Animal Welfarism Continues To Fail, Lori Marino
Why Animal Welfarism Continues To Fail, Lori Marino
Animal Sentience
Welfarism prioritizes human interests over the needs of nonhuman animals. Despite decades of welfare efforts other animals are mostly worse off than ever before, being subjected to increasingly invasive and harmful treatments, especially in the factory farming and biomedical research areas. A legal rights-based approach is essential in order for other animals to be protected from the varying ethical whims of our species.

This study reports the potential of cold atmospheric plasma (CAP) as a versatile tool for delivering oligonucleotides into mammalian cells. Compared to lipofection and electroporation methods, plasma transfection showed a better uptake efficiency and less cell death in the transfection of oligonucleotides. We demonstrated that the level of extracellular aqueous reactive oxygen species (ROS) produced by gas plasma is correlated with the uptake efficiency and that this is achieved through an increase of intracellular ROS levels and the resulting increase in cell membrane permeability. This finding was supported by the use of ROS scavengers, which reduced CAP-based uptake efficiency. In …
