A Wolf In Military Clothing: A Case Study Examination Of Lone Wolf Terrorism And The Roles And Responsibilities Of Government Agencies, Peter Bandel Jan 2012

A Wolf In Military Clothing: A Case Study Examination Of Lone Wolf Terrorism And The Roles And Responsibilities Of Government Agencies, Peter Bandel

Electronic Theses and Dissertations

Since the fall of September, 2011, there has been a major increase in awareness and study of global terrorism. Academia, the media, politicians, and the average citizen all have varying definitions, ideas, and concerns about terrorism. The focus has mainly been on international terrorism. Terrorist organizations like Al Qaeda have permeated the discussion. However, there is a growing concern of the "lone wolf terrorist." A lone wolf terrorist acts without a terrorist organization and is capable of having his/her own radical agenda with the audacity and simplicity to carry it out solely and enact great damage. The focus in the …

Quantifying The Impacts Of Oyster Reef Restoration On Oyster Coverage, Wave Attenuation And Seagrass Fragment Retention In Mosquito Lagoon, Florida, Stephanie Garvis

Electronic Theses and Dissertations

The goal of this project was to determine the effects of oyster reef restoration on oyster coverage, wave height dissipation and seagrass recruitment. First, to assess the current versus historical coverage of natural, dead and restored oyster reefs within Mosquito Lagoon, aerial photographs from 2009, provided by Saint Johns River Water Management District, were digitized using ArcGIS software. Live reefs, restored reefs and dead reefs were screen digitized using a reef ‘signature’ in order to estimate the area of each type of reef. The 2009 maps were used as a guide to digitizing the historical aerial photographs (1943, 1951, 1967, …

Expression Of Lipase From Mycobacterium Tuberculosis In Nicotiana Tobacum And Lactuca Sativa Chloroplasts, Bethany Lloyd Jan 2012

Expression Of Lipase From Mycobacterium Tuberculosis In Nicotiana Tobacum And Lactuca Sativa Chloroplasts, Bethany Lloyd

Electronic Theses and Dissertations

Tuberculosis (TB), caused by the bacterium Mycobacterium tuberculosis (M. tuberculosis), is a global threat and the leading cause of death among individuals infected with HIV. TB treatment requires multi-drug cocktails, due to the increasing rates of drug resistance of the bacterium. With multi-drug cocktails, strains have been documented to be resistant to all major drugs in the fight against TB. Since the strains are drug resistant, it calls for an increasing need for vaccine and treatment development for the purpose of preventing and managing the disease. The most widely distributed vaccine against TB is Bacillus Calmette-Gue´rin (BCG). Apart from being …

Cerium Oxide Nanoparticles Act As A Unique Catalyst And Scavenge Nitric Oxide And Peroxynitrite And Decrease Rns In Vitro And In Vivo, Janet Dowding

Electronic Theses and Dissertations

Cerium oxide nanoparticles (CeO2 NPs)(nanoceria) have been shown to possess a substantial oxygen storage capacity via the interchangeable surface reduction and oxidation of cerium atoms, cycling between the Ce4+ and Ce3+ redox states. Reduction of Ce4+ to Ce3+ causes oxygen vacancies or defects on the surface of the crystalline lattice structure of the particles, generating a cage for redox reactions to occur. The study of the chemical and biological properties of CeO2 NPs has expanded recently, and the methods used to synthesize these materials are also quite diverse. This has led to a plethora of studies describing various preparations of …

A Study Of The Degradative Capabilities Of The Bimetallic System: Mg(Pd/C) As Applied In The Destruction Of Decafluoropentane, An Environmental Contaminant, Douglas Tomlin Jan 2012

A Study Of The Degradative Capabilities Of The Bimetallic System: Mg(Pd/C) As Applied In The Destruction Of Decafluoropentane, An Environmental Contaminant, Douglas Tomlin

Electronic Theses and Dissertations

Pollution from hydrofluorocarbons (HFC) poses a serious challenge to the environmental community. Released from industrial operations, they have contaminated both the atmosphere and groundwater and are considered persistent in both media.1 For over the past 20 years, the practice of synthesizing hydrofluorocarbons as alternatives to chlorofluorocarbons (CFC) has been conducted in an effort to reverse the effects of stratospheric ozone layer depletion. 2,3 However, in doing so these new fluorinated compounds exhibited an unexpected property as a potent global warming greenhouse gas (GHG) with radiative forcing potentials in the range of 100 to 10,000 equivalents greater than carbon dioxide.4 Conversely, …

Conservation And Population Biology: Genetics, Demography And Habitat Requirements Of The Atlantic Coast Beach Mice, Haakon Myklevoll Kalkvik Jan 2012

Conservation And Population Biology: Genetics, Demography And Habitat Requirements Of The Atlantic Coast Beach Mice, Haakon Myklevoll Kalkvik

Electronic Theses and Dissertations

The conservation biology field seeks to preserve biodiversity and the processes shaping that variation. Conservation biology is intimately tied to evolutionary research, in order to identify evolutionary distinct lineages that may be in danger of disappearing. Interestingly, patterns and processes of lineage divergence and persistence change with respect to spatial and temporal scale. I seek to evaluate biodiversity, the factors that have shaped this heterogeneity, and how this variability persists. To accomplish this I used a phylogeographic approach as well as niche and population modeling on the Peromyscus maniculatus species group found widely distributed in North America. My emphasis was …

Manipulation Of Host Signal Transduction Pathways And Cytoskeleton Functions By Invasive Bacterium Listeria Monocytogenes And Chlamydia Trachomatis, Shahanawaz Jiwani Jan 2012

Manipulation Of Host Signal Transduction Pathways And Cytoskeleton Functions By Invasive Bacterium Listeria Monocytogenes And Chlamydia Trachomatis, Shahanawaz Jiwani

Electronic Theses and Dissertations

Infectious disease remains one of the leading causes of morbidity and mortality worldwide. Many bacteria that cause disease have the capacity to enter into eukaryotic cells such as epithelial cells and tissue macrophages. Gaining access into the intracellular environment is one of the most critical steps in their survival and/or in pathogenesis. The entry mechanisms employed by these organisms vary considerably, but most mechanisms involve sabotaging and manipulating host cell functions. Invasion of epithelial cells involves triggering host signal transduction mechanisms to induce cytoskeleton rearrangement, thereby facilitating bacterial uptake. My work focuses on understanding the molecular mechanisms employed by bacterial …

Beyond Building A Tree: Phylogeny Of Pitvipers And Exploration Of Evolutionary Patterns, Allyson Fenwick Jan 2012

Beyond Building A Tree: Phylogeny Of Pitvipers And Exploration Of Evolutionary Patterns, Allyson Fenwick

Electronic Theses and Dissertations

As generic and higher-scale evolutionary relationships are increasingly well understood, systematists move research in two directions: 1) understanding specieslevel relationships with dense taxon sampling, and 2) evaluating evolutionary patterns using phylogeny. In this study I address both foci of systematic research using pitvipers, subfamily Crotalinae. For direction one, I evaluate the relationships of 96% of pitvipers by combining independent sets of molecular and phenotypic data. I find the inclusion of species with low numbers of informative characters (i.e. less than 100) negatively impacts resolution of the phylogeny, and the addition of independent datasets has no effect on or a small …

Assessment Of Molecular Interactions Via Magnetic Relaxation: A Quest For Inhibitors Of The Anthrax Toxin, Oscar Santiesteban Jan 2012

Assessment Of Molecular Interactions Via Magnetic Relaxation: A Quest For Inhibitors Of The Anthrax Toxin, Oscar Santiesteban

Electronic Theses and Dissertations

Anthrax is severe disease caused by the gram-positive Bacillus anthracis that can affect humans with deadly consequences. The disease propagates via the release of bacterial spores that can be naturally found in animals or can be weaponized and intentionally released into the atmosphere in a terrorist attack. Once inhaled, the spores become activated and the anthrax bacterium starts to reproduce and damage healthy macrophages by the release of the anthrax toxin. The anthrax toxin is composed of three virulent factors: (i) anthrax protective antigen (APA), (ii) anthrax lethal factor (ALF), and (iii) anthrax edema factor (AEF) that work in harmony …

Defective Dynamics Of Mitochondria In Amyotrophic Lateral Sclerosis And Huntington's Disease, Wenjun Song Jan 2012

Defective Dynamics Of Mitochondria In Amyotrophic Lateral Sclerosis And Huntington's Disease, Wenjun Song

Electronic Theses and Dissertations

Mitochondria play important roles in neuronal function and survival, including ATP production, Ca2+ buffering, and apoptosis. Mitochondrial dysfunction is a common event in the pathogenesis of neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) and Huntington's disease (HD); however, what causes the mitochondrial dysfunction remains unclear. Mitochondrial fission is mediated by dynamin-related protein 1 (DRP1) and fusion by mitofusin 1/2 (MFN1/2) and optic atrophy 1 (OPA1), which are essential for mitochondrial function. Mutations in the mitochondrial fission and fusion machinery lead to neurodegeneration. Thus, whether defective mitochondrial dynamics participates in ALS and HD requires further investigation. ALS is a fatal …

Novel Immunogens Of Cellular Immunity Revealed Using In Vitro Human Cell-Based Approach, Brian Schanen Jan 2012

Novel Immunogens Of Cellular Immunity Revealed Using In Vitro Human Cell-Based Approach, Brian Schanen

Electronic Theses and Dissertations

In the last 150 years, tremendous headway has been made in our understanding of the human immune system. Pioneers in the field such as Paul Ehrlich, Elie Metchnikoff, Louis Pasteur, Robert Koch and Walter Reed carried out seminal studies that established the groundwork for our understanding of humoral and cellular immunity in humans. However, this direct line of evidence into human immunology was diverted in the mid-20th century with the adoption of a model which allowed for investigators to use a reductionist-approach with the promise to resolve immunity at a molecular level. This revolutionary model was the scientific commercialization of …

Somatechnologies Of Body Size Modification: Posthuman Embodiment And Discourses Of Health, Meghan Griffin Jan 2012

Somatechnologies Of Body Size Modification: Posthuman Embodiment And Discourses Of Health, Meghan Griffin

Electronic Theses and Dissertations

This project focuses on persistent gaps in philosophies of the body: the enduring mindbody divide in accounts of phenomenology, the unfulfilled promises of representing and inhabiting the body in online and virtual spaces, and the difference between health as quantified in medical discourse versus health as lived experience. These tensions are brought to light through the electronic food journal genre where the difficulty in capturing pre-noetic, outsideconsciousness aspects of experience and embodied health are thrown into relief against circulating cultural discourses surrounding health, body size, self-surveillance, and self-care. The electronic food journal genre serves as a space for users to …

Hidden Variable, Heather Harms Jan 2012

Hidden Variable, Heather Harms

Electronic Theses and Dissertations

Hidden Variable is a novel that blends linear storytelling with the novel-in-stories form. It poses questions about the nature of identity as well as the feasibility of personal power, particularly with respect to disorders of the mind. Darla Pierson, the novel’s protagonist, is a woman in crisis. She is steeped in selfloathing brought on by the knowledge that she has, in effect, become her dead father—a genius with an epic libido, habitually using and discarding people. Her father has another habit that Darla doesn’t share: being struck by lightning. After the second strike kills him, Darla makes a conscious attempt …

Medical School Prerequisite Courses Completed At Two-Year Colleges By Medical School Matriculants: An Analysis At The University Of Central Florida, Erin Myszkowski Jan 2012

Medical School Prerequisite Courses Completed At Two-Year Colleges By Medical School Matriculants: An Analysis At The University Of Central Florida, Erin Myszkowski

Electronic Theses and Dissertations

Many medical school admissions personnel and pre-health advisors advise premedical students not to take the medical school prerequisite courses at two-year colleges because they believe the courses are less academically rigorous than the same courses at four-year institutions (Losada, 2009; Marie, 2009; Thurlow, 2008, 2009a, 2009b). According to this belief, premedical students who complete the medical school prerequisite courses at a two-year college could be at a disadvantage in regard to medical school admission compared to those students who complete the medical school prerequisite courses at a four-year institution. In an effort to analyze these perceptions, this study examined factors …

The Machine, The Victim, And The Third Thing: Navigating The Gender Spectrum In Margaret Atwood's Oryx And Crake And The Year Of The Flood, Lindsay Mccoy Anderson Jan 2012

The Machine, The Victim, And The Third Thing: Navigating The Gender Spectrum In Margaret Atwood's Oryx And Crake And The Year Of The Flood, Lindsay Mccoy Anderson

Electronic Theses and Dissertations

This thesis explores Atwood's depiction of gender in Oryx and Crake and The Year of the Flood. In an interview from 1972, Margaret Atwood spoke on survival: "People see two alternatives. You can be part of the machine or you can be something that gets run over by it. And I think there has to be a third thing." I assert that Atwood depicts this "third thing" through her characters who navigate between the binaries of "masculine" and "feminine" in a third realm of gender. As the female characters—regardless of their passive or aggressive behavior—engage in a quest for agency, …

Harvesting The Seeds Of Early American Human And Nonhuman Animal Relationships In William Bartram's Travels, The Travel Diary Of Elizabeth House Trist, And Sarah Trimmer's Fabulous Histories, Leslie Blake Vives Jan 2012

Harvesting The Seeds Of Early American Human And Nonhuman Animal Relationships In William Bartram's Travels, The Travel Diary Of Elizabeth House Trist, And Sarah Trimmer's Fabulous Histories, Leslie Blake Vives

Electronic Theses and Dissertations

This thesis uses ecofeminist and human-animal studies lenses to explore human animal and nonhuman animal relations in early America. Most ecocritical studies of American literature begin with nineteenth-century writers. This project, however, suggests that drawing on ecofeminist theories with a human-animal studies approach sheds light on eighteenth-century texts as well. Early American naturalist travel writing offers a site replete with human and nonhuman encounters. Specifically, naturalist William Bartram's travel journal features interactions with animals in the southern colonial American frontier. Amateur naturalist Elizabeth House Trist's travel diary includes interactions with frontier and domestic animals. Sarah Trimmer's Fabulous Histories, a conduct …

Life History Response To Infection And The Potential For Dishonest Signals In The Ground Cricket, Allonemobius Socius, Emily Copeland Jan 2012

Life History Response To Infection And The Potential For Dishonest Signals In The Ground Cricket, Allonemobius Socius, Emily Copeland

Electronic Theses and Dissertations

In order to maximize fitness, individuals must partition their limited resources among competing physiological processes, creating negative statistical associations between processes known as “life-history trade-offs”. Evidence indicates that individuals tend to decrease their reproductive investment when confronted with a significant immunological challenge in order to increase investment in immune defense. This trade-off is often accompanied by a significant decrease in the sexual signal, which provides an honest signal of the male’s infection status to potential mates. However, if individual residual reproductive value is low, they may instead increase their reproductive investment to maximize reproductive success before the end of their …

Two Conceptions Of The Mind, Benjamin J. Aguda Dec 2011

Two Conceptions Of The Mind, Benjamin J. Aguda

HIM 1990-2015

Since the cognitive revolution during the last century the mind has been conceived of as being computer-like. Like a computer, the brain was assumed to be a physical structure (hardware) upon which a computational mind (software) was built. The mind was seen as a collection of independent programs which each have their own specific tasks, or modules. These modules took sensory input "data" and transduced it into language-like representations which were used in mental computations. Recently, a new conception of the mind has developed, grounded cognition. According to this model, sensory stimulus is saved in the original format in which …

Spatial Ability And Experts Of Needlework Crafts An Exploratory Study, Shannon Kyle Tedder Bailey

HIM 1990-2015

In the Surface Development Test, self-perceived Sewing Expertise was significant in predicting participants' test scores. For the Paper Folding Test, Knitting and Crocheting Expertise were significant, suggesting expertise may mitigate age effects.; Spatial ability has been a topic of much research and debate over the past few decades. Yet, there are gaps in the current literature. Spatial ability refers to the aptitude of an individual to mentally rotate objects, visualize spaces, and recognize patterns (Linn & Petersen, 1985). A highly spatial task that is not addressed in research literature is crafting. Crafting may refer to knitting, crocheting, sewing, and other …

Using Gis To Determine The Influence Of Wetlands On Cayuga Iroquois Settlement Location Strategies, David J. Birnbaum Dec 2011

Using Gis To Determine The Influence Of Wetlands On Cayuga Iroquois Settlement Location Strategies, David J. Birnbaum

HIM 1990-2015

The archaeological record of the Iroquois supports that settlements were regularly relocated during the protohistoric period (1500-1650 A.D.). With the use of Geographic Information Systems (GIS) computer software, archaeologists may analyze variables potentially resulting in or influencing the movement of settlements. Through the use of spatial analysis, I argue that Cayuga Iroquois settlement locations were influenced by the environmental characteristics of their surrounding landscape. Specifically, wetlands are believed to have influenced settlement location choices in central New York state. This study examines the spatial relationships between wetland habitats and protohistoric period Cayuga Iroquois settlements where swidden maize agriculture comprised most …

What Is The Importance Of Age At Menarche On Adult Height Relative To Other Known Factors?, Pamela M. Kacerosky Dec 2011

What Is The Importance Of Age At Menarche On Adult Height Relative To Other Known Factors?, Pamela M. Kacerosky

HIM 1990-2015

Objectives: To analyze the association between age at menarche, as a measure of sexual maturation, and adult height from ten published studies. Methods: Compared published measurements of age at menarche, adult height, and within-sample relationships observed in ten studies, for women from several societies and socioeconomic backgrounds, living in the 20th century, Results: In these studies, early maturers were taller during pre-puberty, but had shorter adult height then later maturers. Late maturers experience a longer period of pre-pubertal growth and a delayed age of peak height velocity, leading to an extended overall time of growth, until adult stature was obtained. …
