Book Of Empire: The Political Bible Of U.S. Literary Modernism, Barry Hudek

Electronic Theses and Dissertations

“Book of Empire” reveals that contrary to what is often suggested by scholars, modernism is not a moment of secularization and declining faith and that the Bible is actually a resource for mounting a radical critique of empire, nation-building, and racial oppression that defies conservative notions supporting those undertakings. For Willa Cather, William Faulkner, and Zora Neale Hurston, the Bible is a source of moral authority they use to challenge the imperialist, colonialist, and nativist projects of the twentieth-century U.S. In rebranding the Bible as politically radical, these writers are not denying the authority of the Bible, but are re-appropriating …

Asymptotic Properties Of Polynomials Orthogonal Over Multiply Connected Domains, James A. Henegan

Electronic Theses and Dissertations

We investigate the asymptotic behavior of polynomials orthogonal over certain multiply connected domains. Each domain that we consider has an analytic boundary and is, in a strong sense, conformally equivalent to a canonical type of multiply connected domain called a circular domain. The two most general results involve the construction of a series expansion and an integral representation for these polynomials. We show that the integral representation can be utilized to derive more specific results when the domain of orthogonality is circular. In this case, we shed light on the manner in which the holes in the domain of orthogonality …

Responses Of The Ocellated Turkey (Meleagris Ocellata) To Human Disturbance, Thomas Hughes Martin

Electronic Theses and Dissertations

Habitat loss and habitat degradation are major drivers of the current biodiversity crisis. Nowhere else are these threats more severe than in the tropics. Because the tropics are estimated to contain as much as 60% of all the species on Earth, they are critically important for the conservation of biodiversity. To conserve species we need to understand both the factors that lead to extinction and how the taxa that persist are able to adapt to the rapid anthropogenic change of their environment. The Ocellated Turkey (Meleagris ocellata) is a Neotropical galliform bird of conservation concern because it faces a rapidly …

Leadership And Subordinate Engagement: A Meta-Analytic Examination Of Its Mechanisms Using Self-Determination Theory, Henry Young

Electronic Theses and Dissertations

Although past research has suggested ineffective leadership to be the most common reason for low levels of employee engagement, little is known about the mediating mechanisms underlying this relationship. To address this gap in research, I tested a theoretical model based on Self-Determination Theory (SDT; Deci & Ryan, 2000) in which two focal mechanisms, leader-member exchange (LMX) and empowerment, functioned in sequential order to predict the relationship between Full Range Leadership and subordinate engagement. Results showed that transactional leadership had positive and negative indirect effects on engagement, suggesting that transactional leadership comprises a "double-edged sword" as a predictor of subordinate …

Since of the enormous content, I shall only pay particular attention to Copernicus and Newton in which the emerging sciences transformed the cosmos on what Alexandre Koyré calls from a "closed world to infinite universe". As an interdisciplinary approach, I used the methods and inquiries …

Advanced Liquid Crystal Displays With Supreme Image Qualities, Haiwei Chen

Electronic Theses and Dissertations

Several metrics are commonly used to evaluate the performance of display devices. In this dissertation, we analyze three key parameters: fast response time, wide color gamut, and high contrast ratio, which affect the final perceived image quality. Firstly, we investigate how response time affects the motion blur, and then discover the 2-ms rule. With advanced low-viscosity materials, new operation modes, and backlight modulation technique, liquid crystal displays (LCDs) with an unnoticeable image blur can be realized. Its performance is comparable to an impulse-type display, like cathode ray tube (CRT). Next, we propose two novel backlight configurations to improve an LCD's …

Cafeteria Culture: An Anthropological Approach To Lunchtime In A Central Florida Elementary School, Emily Herrington

Enhanced Ablation By Femtosecond And Nanoseond Pulses, Haley Kerrigan

Electronic Theses and Dissertations

Laser ablation of GaAs by a combination of femtosecond and nanosecond pulses is investigated as a means of enhancing material removal by a femtosecond pulse in the filamentation intensity regime. We demonstrate for the first time increased ablation of GaAs by ultrafast laser pulse plasmas augmented by nanosecond pulse radiation from a secondary laser. Material removal during laser ablation is a complex process that occurs via multiple mechanisms over several timescales. Due to different pulse durations, ablation by femtosecond and nanosecond pulses are dominated by different mechanisms. Ablation can be enhanced by optimally combining a femtosecond and nanosecond pulse in …

A Major Dna Double Strand Repair Pathway And Cancer-Associated Circulating Proteins Are Effecters Of Epigenetic Revision., Brittany Allen

Electronic Theses and Dissertations

DNA methylation is a vital epigenetic process that acts as a major control mechanism for gene expression. In addition to its essential role in many normal cellular processes, it is also implicated in a wide variety of disease states and processes including cancer. Along with genetic mutations, aberrant DNA methylation patterns, specifically the inappropriate DNA methylation or demethylation of CpG residues, may activate oncogenes or suppress tumor suppressor genes, respectively. These changes can generate or facilitate the progression of tumorigenesis and tend to accumulate throughout the development of cancer. Although they play such a major role in cancer and in …

Carbon Nanotube (Cnt) Metallic Composite With Focus On Processing And The Resultant Properties, Md Muktadir Billah

Electronic Theses and Dissertations

Metal-carbon nanotubes (CNTs) composites are the promising advanced materials that are being developed to take the advantage of the exceptional properties of CNTs. Because of the intrinsically strong in-plane atomic SP2 bonding CNTs offer high young's modulus (1.0–1.8 TPa), high tensile strength (30–200 GPa) and high elongation at break (10–30%). The thermal conductivity of individual single-walled carbon nanotube (SWCNT) and multi-walled carbon nanotube (MWCNT) are about 6000 W/m-K and 3000 W/m-K, respectively. Therefore it is expected that by incorporation of CNTs in metal matrices multi-functional composites can be used ideally as thermal interface materials, light-weight high-strength structural materials, electric components, …
