Cathedral of Hope: A History of Progressive Christianity, Civil Rights, and Gay Social Activism in Dallas, Texas, 1965 - 1992
This abstract is for the thesis on the Cathedral of Hope (CoH). The CoH is currently the largest church in the world with a predominantly gay and lesbian congregation. This work tells the history of the church which is located in Dallas, Texas. The thesis employs over 48 sources to help tell the church's rich history which includes a progressive Christian philosophy, an important contribution to the fight for gay civil rights, and fine examples of courage through social activism. This work makes a contribution to gay history as well as civil rights history. It also adds to the cultural and social history which concentrates on the South and Southwestern regions of the United States.

Clutch
Clutch is the title of the creative portion of my thesis as well as the name of my theory 'clutch' which I outline in the preface section. The purpose of the clutch theory is to recognize modes of inspiration in the body, heart and mind so that the poet can consciously move beyond passive receptivity to engage inspiration more fully. Mechanically, to "clutch" does not mean to create inspiration, but it is the opportunistic, spirited encouragement of these moments of inspiration and, more importantly, the direction of the artist's own response in moving from inspiration to creation. The clutch process unfolds through three centers: body, heart and mind, where we initially encounter inspiration. And, through a discussion of three notable poets' work, Henri Cole, Li-Young Lee and T.S. Eliot, the relationship between a completed work and clutch as a process further explains the boundaries of each mode.

A Comparison of Miranda Procedures: The Effects of Oral and Written Administrations on Miranda Comprehension
Millions of custodial suspects waive their rights each year without the benefit of legal counsel. The question posed to psychologists in disputed Miranda waivers is whether this waiver decision was, knowing, intelligent, and voluntary. Mental health professionals must be aware of potential barriers to Miranda comprehension to provide expert opinions regarding a defendant's competency to waive rights. The current study examined how Miranda warning reading level, length, and method of administration affects Miranda comprehension. Recently arrested detainees at Grayson County Jail were administered oral and written Miranda warnings from the Miranda Statements Scale (MSS; Rogers, 2005) to measure their comprehension of the warnings. Surprisingly low levels of Miranda comprehension were found for most warnings. For all warnings at or above 8th grade, a substantial minority (27.1% - 39.6%) of defendants exhibited failed (i.e., < 50% understanding) Miranda comprehension. Regardless of other variables, oral administrations resulted in a substantially larger number of defendants with failed Miranda comprehension. Implications for public policy and clinical practice are discussed.

Comparison of Source Diversity and Channel Diversity Methods on Symmetric and Fading Channels.
Channel diversity techniques are effective ways to combat channel fading and noise in communication systems. In this thesis, I compare the performance of source and channel diversity techniques on fading and symmetric continuous channels. My experiments suggest that when SNR is low, channel diversity performs better, and when SNR is high, source diversity shows better performance than channel diversity.

Computational Epidemiology - Analyzing Exposure Risk: A Deterministic, Agent-Based Approach
Many infectious diseases are spread through interactions between susceptible and infectious individuals. Keeping track of where each exposure to the disease took place, when it took place, and which individuals were involved in the exposure can give public health officials important information that they may use to formulate their interventions. Further, knowing which individuals in the population are at the highest risk of becoming infected with the disease may prove to be a useful tool for public health officials trying to curtail the spread of the disease. Epidemiological models are needed to allow epidemiologists to study the population dynamics of transmission of infectious agents and the potential impact of infectious disease control programs. While many agent-based computational epidemiological models exist in the literature, they focus on the spread of disease rather than exposure risk. These models are designed to simulate very large populations, representing individuals as agents, and using random experiments and probabilities in an attempt to more realistically guide the course of the modeled disease outbreak. The work presented in this thesis focuses on tracking exposure risk to chickenpox in an elementary school setting. This setting is chosen due to the high level of detailed information realistically available to …

The Debate over the Corporeality of Demons in England, c. 1670-1700
According to Walter Stephens, witch-theorists in the fifteenth century developed the witchcraft belief of demon copulation in order to prove the existence of demons and therefore the existence of God. In England, during the mid-seventeenth century, Cartesian and materialist philosophies spread. These new philosophies stated there was nothing in the world but corporeal substances, and these substances had to conform to natural law. This, the philosophers argued, meant witchcraft was impossible. Certain other philosophers believed a denial of any incorporeal substance would lead to atheism, and so used witchcraft as proof of incorporeal spirits to refute what they felt was a growing atheism in the world. By examining this debate we can better understand the decline of witchcraft. This debate between corporeal and incorporeal was part of the larger debate over the existence of witchcraft. It occurred at a time in England when the persecution of witches was declining. Using witchcraft as proof of incorporeal substances was one of the last uses of witchcraft before it disappeared as a valid belief. Therefore, a better understanding of this debate adds to a better understanding of witchcraft during its decline.

Deliberative Democracy, Divided Societies, and the Case of Appalachia
Theories of deliberative democracy, which emphasize open-mindedness and cooperative dialogue, confront serious challenges in deeply divided political populations constituted by polarized citizens unwilling to work together on issues they collectively face. The case of mountaintop removal coal mining in Appalachia makes this clear. In my thesis, I argue that such empirical challenges are serious, yet do not compromise the normative desirability of deliberative democracy because communicative mechanisms can help transform adversarial perspectives into workable, deliberative ones. To realize this potential in divided societies, mechanisms must focus on healing and reconciliation, a point under-theorized by deliberativists who do not take seriously enough the feminist critique of public-private dualisms that illuminates political dimensions of such embodied processes. Ultimately, only a distinctly two-stage process of public deliberation in divided populations, beginning with mechanisms for healing and trust building, will give rise to the self-transformation necessary for second-stage deliberation aimed at collectively binding decisions.

Effect of a Stimulus Shaping Procedure on Fluent Letter Sound Acquisition.
Numerous studies have evaluated and confirmed many benefits of errorless learning and fluency-based procedures. The purpose of this study was to evaluate the benefits of combining an errorless learning procedure, stimulus shaping, and fluency-based procedures to teach see/say letter sound discriminations to three preschool children. Participants were taught 6 letter sounds using a hear/point stimulus shaping procedure followed by a see/say fluency-based procedure. A second letter set was taught using only the fluency-based procedure. Results showed that combining the procedures reduced the amount of teaching time by up to 40% and the percent of errors by up to 50%. This preliminary evidence shows exceptional promise in application of this combination of procedures to teach letter sounds to preschool children.

End of Insertion Detection in Colonoscopy Videos
Colorectal cancer is the second leading cause of cancer-related deaths behind lung cancer in the United States. Colonoscopy is the preferred screening method for detection of diseases like Colorectal Cancer. In the year 2006, American Society for Gastrointestinal Endoscopy (ASGE) and American College of Gastroenterology (ACG) issued guidelines for quality colonoscopy. The guidelines suggest that on average the withdrawal phase during a screening colonoscopy should last a minimum of 6 minutes. My aim is to classify the colonoscopy video into insertion and withdrawal phase. The problem is that currently existing shot detection techniques cannot be applied because colonoscopy is a single camera shot from start to end. An algorithm to detect phase boundary has already been developed by the MIGLAB team. Existing method has acceptable levels of accuracy but the main issue is dependency on MPEG (Moving Pictures Expert Group) 1/2. I implemented exhaustive search for motion estimation to reduce the execution time and improve the accuracy. I took advantages of the C/C++ programming languages with multithreading which helped us get even better performances in terms of execution time. I propose a method for improving the current method of colonoscopy video analysis and also an extension for the same to …

Formulaic sequences in English conversation: Improving spoken fluency in non-native speakers.
Native speakers often ignore the limitless potential of language and stick to institutionalized formulaic sequences. These sequences are stored and processed as wholes, rather than as the individual words and grammatical rules which make them up. Due to research on formulaic sequence in spoken language, English as a Second Language / Foreign Language pedagogy has begun to follow suit. There has been a call for a shift from the traditional focus on isolated grammar and vocabulary to formulaic sequences and context. I tested this hypothesis with 19 L2 English learners who received 5 weeks of task-based instruction and found substantial progress in oral fluency only for the experimental group. Differences between pretest and posttest oral fluency were examined by looking at the learners' speech rate and their mean length of run. Subjective evaluation of fluency by 16 native English judges confirmed the calculated measures.

FPGA Implementation of Low Density Party Check Codes Decoder
Reliable communication over the noisy channel has become one of the major concerns in the field of digital wireless communications. The low density parity check codes (LDPC) has gained lot of attention recently because of their excellent error-correcting capacity. It was first proposed by Robert G. Gallager in 1960. LDPC codes belong to the class of linear block codes. Near capacity performance is achievable on a large collection of data transmission and storage.In my thesis I have focused on hardware implementation of (3, 6) - regular LDPC codes. A fully parallel decoder will require too high complexity of hardware realization. Partly parallel decoder has the advantage of effective compromise between decoding throughput and high hardware complexity. The decoding of the codeword follows the belief propagation alias probability propagation algorithm in log domain. A 9216 bit, (3, 6) regular LDPC code with code rate ½ was implemented on FPGA targeting Xilinx Virtex 4 XC4VLX80 device with package FF1148. This decoder achieves a maximum throughput of 82 Mbps. The entire model was designed in VHDL in the Xilinx ISE 9.2 environment.

Grayson County, Texas, in Depression and War: 1929-1946
The economic disaster known as the Great Depression struck Grayson County, Texas, in 1929, and full economic recovery did not come until the close of World War II. However, the people of Grayson benefited greatly between 1933 and 1946 from the myriad spending programs of the New Deal, the building of the Denison Dam that created Lake Texoma, and the establishment of Perrin Army Air Field. Utilizing statistical data from the United States Census and the Texas Almanac, this thesis analyzes the role of government spending‐federal, state, and local‐in the economic recovery in Grayson County.

Immediate and Subsequent Effects of Fixed-Time Delivery of Therapist Attention on Problem Behavior Maintained by Attention
The purpose of the current study was to investigate the immediate and subsequent effects of fixed-time attention on problem behavior maintained by therapist attention utilizing a three-component multiple-schedule design. The treatment analysis indicated that fixed-time attention produced a significant immediate decrease in the frequency of physically disruptive behavior (PDB), represented by low frequencies of PDB in Component 2, as well as a continued subsequent effect, represented by lower frequencies of problem behavior in Component 3 when compared to Component 1. The possible behavioral mechanisms responsible for the observed suppression in Component 2 of the treatment analysis are discussed. Evidence of behavioral contrast was observed in Components 1 and 3 of the treatment analysis in conditions in which Component 2 contained a fixed-time schedule of stimulus delivery. In addition, limitations and future research are outlined.

Impacts of Blogging Motivation and Flow on Blogging Behavior
With the development of free and easy-to-use software programs, blogging has helped turn Web consumers into Web content providers. Blogging provides distinctive insight into comprehending e-consumer behavior explicitly with respect to social networking and information searching behaviors while facilitating a state of flow. The objectives of this study are to identify determinant dimensions of blogging motivations and flow, and to investigate the hypothesized relationships of the motivational blogging behavior. Analyzing data (n = 432) from a southwestern university, results reveal the critical dimensions of motivations, behaviors, and flow in blogging. Upon extending Hoffman and Novak's (1996) flow model, 14 out of 26 hypotheses were confirmed regarding the significant impacts of blogging motivations and flow on blogging behaviors. The findings revealed that the desire for information, enjoyment, and loyalty are the primary drivers for experiential blogging behavior. Specifically, information-seeking is the decisive motivation to urge experiential and e-shopping behavior concurrently. This study shows that indulgence and telepresence in flow might play pivotal mediating roles to promote the goal-oriented e-shopping behavior resulting enjoyment and loyalty-seeking motivations.

An Informational Theory of Midterm Elections: The Impact of Iraq War Deaths on the 2006 Election.
There has been much scholarly attention directed at the Iraq war's role in determining voter choice. I attempt to extend that research into voter turnout to determine what role the Iraq war played in 2006 voter turnout. This paper argues that turnout at the state level could be explained by the number of US deaths each state had sustained from the Iraq occupation at the time of the election. A theory of voter activation based on information availability is put forth to explain the relationship between national events and voter turnout wherein national events like the Iraq war will raise the amount of information voters have at their disposal, which will increase the likelihood of their voting on election day. Regression analysis comparing the turnout rates of the 50 states to their casualties in Iraq revealed no relationship between the two factors, indicating that something else is responsible for the high turnout of the midterm.

Interweaving History: The Texas Textile Mill and McKinney, Texas, 1903-1968.
Texas textile mills comprise an untold part of the modern South. The bulk of Texas mills were built between 1890 and 1925, a compressed period of expansion in contrast to the longer developmental pattern of mills in the rest of the United States. This compression meant that Texas mill owners benefited from knowledge gained from mill expansion elsewhere, and owners ran their mills along the same lines as the dominant southeastern model. Owners veered from the established pattern when conditions warranted. This case study focuses on three mills in Texas that operated both independently and as a corporation for a total of sixty years. One mill in McKinney dominated the economy of a small town and serves as the primary focus of this paper. A second mill in Waco served a diversified economy in the center of the state; and the third mill, built in Dallas was concentrated in a major city in a highly competitive job market. All three of these mills will illuminate the single greatest difference between Texas mills and mills elsewhere, the composition of the labor force. Women did not dominate the mill labor force in Texas nor did children, except in limited cases, make-up a …

Maternal employment: Factors related to role strain.
Past literature suggests that working mothers are at an increased risk for experiencing role strain compared to other employed adults. The current study investigated attitudes and beliefs of 783 working mothers of 15-month-old children using data from the National Institute of Child Health and Human Development's Study of Early Child Care and Youth Development. Working mothers' levels of role strain was associated with perceived social support, attitudes toward maternal employment, job and parental role quality, financial stress, and depression. Negative attitudes toward maternal employment predicted maternal separation anxiety, while positive attitudes toward employment did not affect separation anxiety. These findings have implications for the importance of decreasing role strain in working mothers.

Missionary Millennium: The American West; North and West Africa in the Christian Imagination
During the 1890s in the United States, Midwestern YMCA missionaries challenged the nexus of power between Northeastern Protestant denominations, industrialists, politicians, and the Association's International Committee. Under Kansas YMCA secretary George Fisher, this movement shook the Northeastern alliance's underpinnings, eventually establishing the Gospel Missionary Union. The YMCA and the GMU mutually defined foreign and domestic missionary work discursively. Whereas Fisher's pre-millennial movement promoted world conversion generally, the YMCA primarily reached out to college students in the United States and abroad. Moreover, the GMU challenged social and gender roles among Moroccan Berbers. Fisher's movements have not been historically analyzed since 1975. Missionary Millennium is a reanalysis and critical reading of religious fictions about GMU missionaries, following the organization to its current incarnation as Avant Ministries.

Modified epoxy coatings on mild steel: A study of tribology and surface energy.
A commercial epoxy was modified by adding fluorinated poly (aryl ether ketone) and in turn metal micro powders (Ni, Al, Zn, and Ag) and coated on mild steel. Two curing agents were used; triethylenetetramine (curing temperatures: 30 oC and 70 oC) and hexamethylenediamine (curing temperature: 80 oC). Variation in tribological properties (dynamic friction and wear) and surface energies with varying metal powders and curing agents was evaluated. When cured at 30 oC, friction and wear decreased significantly due to phase separation reaction being favored but increased when cured at 70 oC and 80 oC due to cross linking reaction being favored. There was a significant decrease in surface energies with the addition of modifiers.

NSAID effect on prostanoids in fishes: Prostaglandin E2 levels in bluntnose minnows (Pimephales notatus) exposed to ibuprofen.
Prostanoids are oxygenated derivatives of arachidonic acid with a wide range of physiological effects in vertebrates including modulation of inflammation and innate immune responses. Nonsteroidal anti-inflammatory drugs (NSAIDs) act through inhibition of cyclooxygenase (COX) conversion of arachidonic acid to prostanoids. In order to better understand the potential of environmental NSAIDS for interruption of normal levels COX products in fishes, we developed an LC/MS/MS-based approach for tissue analysis of 7 prostanoids. Initial studies examining muscle, gut and gill demonstrated that prostaglandin E2 (PGE2) was the most abundant of the measured prostanoids in all tissues and that gill tissue had the highest and most consistent concentrations of PGE2. After short-term 48-h laboratory exposures to concentrations of 5, 25, 50 and 100 ppb ibuprofen, 50.0ppb and 100.0 ppb exposure concentrations resulted in significant reduction of gill tissue PGE2 concentration by approximately 30% and 80% respectively. The lower exposures did not result in significant reductions when compared to unexposed controls. Measured tissue concentrations of ibuprofen indicated that this NSAID had little potential for bioaccumulation (BCF 1.3) and the IC50 of ibuprofen for inhibition of PGE2 production in gill tissue was calculated to be 0.4 µM. Short-term laboratory exposure to ibuprofen did not result in …

On the density of minimal free subflows of general symbolic flows.
This paper studies symbolic dynamical systems {0, 1}G, where G is a countably infinite group, {0, 1}G has the product topology, and G acts on {0, 1}G by shifts. It is proven that for every countably infinite group G the union of the minimal free subflows of {0, 1}G is dense. In fact, a stronger result is obtained which states that if G is a countably infinite group and U is an open subset of {0, 1}G, then there is a collection of size continuum consisting of pairwise disjoint minimal free subflows intersecting U.

Processing, Structure, and Tribological Property Interrelationships in Sputtered Nanocrystalline ZnO Coatings
Solid lubricant coatings with controlled microstructures are good candidates in providing lubricity in moving mechanical assembly applications, such as orthopedics and bearing steels. Nanocrystalline ZnO coatings with a layered wurtzite crystal structure have the potential to function as a lubricious material by its defective structure which is controlled by sputter deposition. The interrelationships between sputtered ZnO, its nanocrystalline structure and its lubricity will be discussed in this thesis. The nanocrystalline ZnO coatings were deposited on silicon substrates and Ti alloys by RF magnetron sputtering with different substrate adhesion layers, direct current biases, and temperatures. X-ray diffraction identified that the ZnO (0002) preferred orientation was necessary to achieve low sliding friction and wear along with substrate biasing. In addition, other analyses such as scanning electron microscopy (SEM), transmission electron microscopy (TEM), and selected area electron diffraction (SAED) were utilized to study the solid lubrication mechanisms responsible for low friction and wear.

Rete Mirabile: An Installation
Rete Mirabile is my new installation piece combining scientific principles with live computer generated music. The title is a Latin term meaning "Wonderful Net," which I use to refer to the highly convoluted network of biological data that drives my installation. The sonification of data, computer modeling of biological processes, kinetic sculptures, and user interactivity are central parts of the installation. The paper is organized as follows: First, brief history of the forerunners that inspired my work is given. This includes a short discussion on how John Cage and David Tudor influenced current artists works, and how those works have influenced my own work. Then I review current installation works that share similarities with my own. Finally, a detailed discussion and analysis of the construction and function concludes the paper.

The Rise and Fall of a Revolutionary Relationship: George Washington and Thomas Paine, 1776-1796
This study is a cultural and political analysis of the emergence and deterioration of the relationship between George Washington and Thomas Paine. It is informed by modern studies in Atlantic history and culture. It presents the falling out of the two Founding Fathers as a reflection of two competing political cultures, as well as a function of the class aspirations of Washington and Paine. It chronologically examines the two men's interaction with one another from the early days of the American Revolution to the Reign of Terror of the French Revolution. Along the way this study highlights the dynamics that characterized the Washington-Paine relationship and shows how the two men worked together to further their own agendas. This study also points to Thomas Paine's involvement with a web of Democratic Societies in America and to Washington's increasing wariness and suspicion of these Societies as agents of insurrection.
