The Continuing Anglican Metamorphosis: Introducing The Adapted Integrated Model, John L'Hommedieu

Electronic Theses and Dissertations

The purpose of this thesis is to develop and test the Advanced Integrated Model, a typological model in the tradition of Weber’s interpretive sociology, as an asset in explaining recent transformations in American Episcopal-Anglican organizations. The study includes an assessment of the church-sect tradition in the sociology of religion and a summary overview of Weber’s interpretive sociology with special emphasis on the nature and construction of idealtypes and their use in analysis. To illustrate the effectiveness of the model a number of institutional rivalries confronting contemporary Episcopal-Anglican organizations are identified and shown to be explainable only from a sociological perspective …

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 …

Front-Line Registered Nurse Job Satisfaction And Predictors: A Meta-Analysis From 1980 - 2009, Deborah Anne Saber

Electronic Theses and Dissertations

Front-line registered nurses (RNs) make up the workforce that directly affect the care of patients in a variety of different healthcare settings. RN job satisfaction is important because it is tied to retention, organizational commitment, workforce safety, patient safety, and cost savings. The strongest predictors have been difficult to determine because workplaces differ, numerous tools to measure satisfaction exist, the workforce is diversified by generations and work positions, and ongoing policy changes directly impact the work of the front-line RN. The strength and stability of the workforce depends on an accurate understanding of the predictors of job satisfaction for the …

High-Efficiency Blue Phase Liquid Crystal Displays, Yan Li

Electronic Theses and Dissertations

Blue phase liquid crystals (BPLCs) have a delicate lattice structure existing between chiral nematic and isotropic phases, with a stable temperature range of about 2 K. But due to short coherent length, these self-assembled nano-structured BPLCs have a fast response time. In the past three decades, the application of BPLC has been rather limited because of its narrow temperature range. In 2002, Kikuchi et al. developed a polymer stabilization method to extend the blue-phase temperature range to more than 60 K. This opens a new gateway for display and photonic applications. In this dissertation, I investigate the material properties of …

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 …

Why Do Individuals Act Fairly Or Unfairly? An Examination Of Psychological And Situational Antecedents Of Organizational Justice, Deshani B. Ganegoda

Electronic Theses and Dissertations

Most studies on organizational justice have focused on individuals’ reactions to justice. As such, a key question has been left largely unanswered: Why do individuals act fairly or unfairly? The present research adopted a person-situation interactionist approach (Trevino, 1986) to examine psychological and situational antecedents of individuals’ fair behavior. The social identity model of deindividuation (SIDE; Reicher, Spears, & Postmes, 1995) and side-bet theory of continuance commitment (Becker, 1960) was used to examine how organizational identification and continuance commitment might influence employees’ fair or unfair behavior depending on an organization’s justice climate. Based on SIDE, it was hypothesized that organizational …

Trade Secrets, Rachel Kolman

Electronic Theses and Dissertations

Trade Secrets is a collection of fourteen short stories that explores characters falling in and out of relationships and coping in unusual and even comedic ways. These characters are often obsessive and do not trust one another. They think life is funny, and discover that love is funny, and yeah, sex can be funny too. They don’t feel the right things when they’re supposed to. They find love, and lose love. They find hope, and lose hope. They escape sometimes, but more often are unable to go anywhere. These stories consider relationships through the disconnection between reality and fantasy, exploring …

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 …

Laser Filamentation Interaction With Materials For Spectroscopic Applications, Matthew Weidman

Electronic Theses and Dissertations

Laser filamentation is a non-diffracting propagation regime consisting of an intense core that is surrounded by an energy reservoir. For laser ablation based spectroscopy techniques such as Laser Induced Breakdown Spectroscopy (LIBS), laser filamentation enables the remote delivery of high power density laser radiation at long distances. This work shows a quasiconstant filament-induced mass ablation along a 35 m propagation distance. The mass ablated is sufficient for the application of laser filamentation as a sampling tool for plasma based spectroscopy techniques. Within the scope of this study, single-shot ablation was compared with multi-shot ablation. The dependence of ablated mass on …

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

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

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 …

Maritime Pirates And Foreign Terrorist Organizations: Complicit Against The United States And Nato?, William Lusk

Electronic Theses and Dissertations

Maritime piracy, a phenomenon which has plagued free maritime trade for thousands of years, has entered a new age of sophistication and global reverberation. These acts of illegal criminal activity in the late twentieth and early twenty-first centuries yield a significant profit margin for the perpetrators while creating considerable cost for ransom payments, security measures, capital, and human life. The classification of maritime pirates, as either criminals hoping to gain financial income or terrorists hoping to usher in political change, is warranted and compelling. If maritime pirates conduct their operations to institute political change, it is possible that flags of …

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 …

Urban Particulate Matter Activates Akt In Human Lung Cells, T. L. Watterson, B. Hamilton, Randy S. Martin, R. A. Coloumb Jr.

Civil and Environmental Engineering Faculty Publications

The normally picturesque Cache Valley in northern Utah is frequently reported to have the worst particulate (PM) air pollution in the United States. Numerous epidemiological studies conducted elsewhere have associated PM exposure to a variety of cardiovascular diseases and early mortality. We have previously shown that Cache Valley PM (CVPM) is pro-inflammatory, through a variety of mechanisms involving the release of inflammatory cytokines, unfolded protein response, ER stress, and C-reactive protein (CRP). This study was undertaken to determine whether Cache Valley PM (CVPM) would activate Akt, an upstream mechanism common to these events. Human lung (BEAS-2B) cells were treated with …

Geographical Assessment Of Microalgae Biofuels Potential Incorporating Resource Availability, Jason C. Quinn, Kimberly Catton, Sara Johnson, Thomas H. Bradley

Mechanical and Aerospace Engineering Faculty Publications

Previous assessments of the economic feasibility and large-scale productivity of microalgae biofuels have not considered the impacts of land and carbon dioxide (CO2) availability on the scalability of microalgae-based biofuels production. To accurately assess the near-term productivity potential of large-scale microalgae biofuel in the US, a geographically realized growth model was used to simulate microalgae lipid yields based on meteorological data. The resulting lipid productivity potential of Nannochloropsis under large-scale cultivation is combined with land and CO2 resource availability illustrating current geographically feasible production sites and corresponding productivity in the US. Baseline results show that CO2 transport constraints will limit …

Spatially Localized Measurement Of Thermal Conductivity Using A Hybrid Photothermal Technique, Zilong Hua, Heng Ban, Marat Khafizov, Robert Schley, Rory Kennedy, David H. Hurley

Mechanical and Aerospace Engineering Faculty Publications

A photothermal technique capable of measuring thermal conductivity with micrometer lateral resolution is presented. This technique involves measuring separately the thermal diffusivity, D, and thermal effusivity, e, to extract the thermal conductivity, k = (e²/D)^1/2. To generalize this approach, sensitivity analysis is conducted for materials having a range of thermal conductivities. Application to nuclear fuel is consider by performing experimental validation using two materials (CaF₂ and SiO₂) having thermal properties representative of fresh and high burnup nuclear fuel. The measured conductivities compare favorably with literature values.

Parametric Study Of The Frequency-Domain Thermoreflectance Technique, C. Xing, C. Jensen, Z. Hua, Heng Ban, D. H. Hurley, M. Khafizov, J. R. Kennedy

Mechanical and Aerospace Engineering Faculty Publications

Without requiring regression for parameter determination, one-dimensional (1D) analytical models are used by many research groups to extract the thermal properties in frequency-domain thermoreflectance measurements. Experimentally, this approach involves heating the sample with a pump laser and probing the temperature response with spatially coincident probe laser. Micron order lateral resolution can be obtained by tightly focusing the pump and probe lasers. However, small laser beam spot sizes necessarily bring into question the assumptions associated with 1D analytical models. In this study, we analyzed the applicability of 1D analytical models by comparing to 2D analytical and fully numerical models. Specifically, we …

Biophysics, Environmental Stochasticity, And The Evolution Of Thermal Safety Margins In Intertidal Limpets, W. Wesley Dowd, M. W. Denny

Biology Faculty Works

As the air temperature of the Earth rises, ecological relationships within a community might shift, in part due to differences in the thermal physiology of species. Prediction of these shifts – an urgent task for ecologists – will be complicated if thermal tolerance itself can rapidly evolve. Here, we employ a mechanistic approach to predict the potential for rapid evolution of thermal tolerance in the intertidal limpet Lottia gigantea. Using biophysical principles to predict body temperature as a function of the state of the environment, and an environmental bootstrap procedure to predict how the environment fluctuates through time, we create …

Electrospun Chitosan Nanofibers For Virus Removal, Bingyu Bai

Dissertations, Master's Theses and Master's Reports - Open

Electrospinning uses electrostatic forces to create nanofibers that are far smaller than conventional fiber spinning process. Nanofibers made with chitosan were created and techniques to control fibers diameter and were well developed. However, the adsorption of porcine parvovirus (PPV) was low. PPV is a small, nonenveloped virus that is difficult to remove due to its size, 18-26 nm in diameter, and its chemical stability. To improve virus adsorption, we functionalized the nanofibers with a quaternized amine, forming N-[(2-hydroxy-3-trimethylammonium) propyl] chitosan chloride (HTCC). This was blended with additives to increase the ability to form HTCC nanofibers. The additives changed the viscosity …
