Mathematical Messiah: Robert Recorde and the Popularization of Mathematics in the Sixteenth Century
Robert Recorde (c. 1510-1557) was a pioneer in the teaching of mathematics in the English language. His attempt to popularize mathematics, in fact, was without precedent in any language. Mathematics in the 1500s was still exclusively reserved for mathematicians, and people in general had no interest in the subject. Within a hundred years after Recorde had popularized mathematics, however, this situation had changed. The scientific revolution of the seventeenth centuty occurred and mathematics became an indispensible aspect of man's knowledge. This thesis examines the background and development of Recorde's attempt to popularize mathematics and evaluates that attempt in terms of its relation to the position of science in the modern world.
God's Estranged Child: Self-Deprecating Images in Edward Taylor's Preparatory Meditations
Throughout his Preparatory Meditations, Edward Taylor used many images to deprecate himself. These images reflected his Puritan religious beliefs rather than an extremely low self-image. The themes of his poetry were taken from the Bible, but they reflected the many duties which befell him in conjunction with his ministry at Westfield. By using images which were most familiar to him and the rhetorical devices of the seventeenth century, Taylor sought to seek God's forgiveness by doing His will--confessing personal guilt, asking for forgiveness, and praising God's mercy. Because the meditations were directed only to God, Taylor never sought to publish them. Like the child he so desperately wanted to be looked upon as, he sought only his father's favor.
A Burkeian Analysis of the Rhetoric of Rebirth in Selected Television Commercials
The purpose of this study was to analyze the content of selected television commercials according to Kenneth Burke's theory of the rhetoric of rebirth. A supplementary Burkeian method called cluster analysis was also used. The analysis revealed, that the rhetoric of rebirth was incorporated in the commercials to stimulate guilt in the television audience. The products offered in the commercials supposedly purged this guilt, transforming the person to a new way of life. The analysis revealed meanings inherent in the word choices for various commercials as well as the potential impact of those words. The study isolated several underlying motifs in the substance of the commercials. The effect of the visual message may cause the audience to overlook the message of the words. Experimental research cited in this study confirms this hypothesis.

Clocks and Mirrors
The essays featured in this collection highlight the gaps, as well as parallels, between mental illness and the human condition. In "Appearances," the narrator struggles with her own visual identity especially after reflecting on her Mom's own lengthy history with the mirror. In "Migrations," the lyrical voice of the narrator carries the reader through the typical day of a clinically depressed female character. Lastly, "Attempting the Fall," addresses the issues society has with mental illness by following the narrator from her suicide attempt to the mental ward.
From Skeletons to Orchards
This thesis is a creative work that is segmented into three main phases in order to display the developing poetic growth and control in the work of Paul Andrew Thies. The first phase is titled "Skeletons and Rhinoceri." It was a phase where I focused on more classical forms of poetry, namely accentual and syllabical sonnets. This phase was greatly influenced by both Charles Baudelaire and William Butler Yeats. The second phase, titled "Clandestinies," was one in which I tried to develop a more dense form. Lord Byron and Pablo Neruda were the two main influences on my work at this time, largely in terms of imaginative exoticism and figurative energy. The third section of this thesis, titled "Graffiti in the Orchard," is an exploration of my current work as a poet. In this phase, Rainer Maria Rilke was the primary influence as I began to develop a more fluid and expressive style.
Homeland Security Roles and Responsibilities: an Examination of Texas Police Chiefs’ Perceptions
Research has shown that the police industry has entered into an era of homeland security. However, whether the core functions of policing have significantly changed since September 11, 2001, has been the topic of considerable debate. Using secondary data, the research identifies variables that are most influential in predicting whether Texas police chiefs understand their departments’ homeland security roles and responsibilities. The data was originally obtained in 2007 through self-administered surveys of police chiefs attending the Texas Chief Leadership Series (TPCLS) and the New Chief Development Program (NCDP).
Sex-Guilt and the Effects of a Subliminal Sex-Related Stimulus on the Libidinal Content of Fictional Narratives
Fictional narratives of 68 female undergraduates classified as either high or low on sex-guilt were rated for libidinal content following subliminal exposure to either a sex-related or a neutral stimulus. Separate dependent measures were obtained for libidinal derivatives bearing either a transparently "close" or a symbolically "distant" relationship to the sex-related stimulus. Subjects in the sex-related stimulus condition expressed significantly fewer close libidinal derivatives than subjects in the neutral condition. High sex-guilt subjects' distant derivative production revealed a near-significant trend toward repression in the neutral condition, but the greatest amount of expression in the sex-related condition. Type of defenses employed are discussed as a function of subliminally perceived stimulus threat.
The Depiction of Women and Negroes in the Fiction of Flannery O'Connor
This thesis is an investigation into the nature of the characterizations of women and Negroes in the fiction of Flannery O'Connor and the extent to which the attitudes, beliefs, and ideas contained in the background of the author influenced such portrayals. The thesis identifies these influences as her native South and the Roman Catholic Church and concludes that her misogynistic treatment of women and sympathetic handling of Negroes proceeds from values placed on both groups in such influences.
"An Encountered Moment"
This MFA graduate thesis explores the intersection of therapeutic photography, generational trauma, and Christian spirituality in promoting spiritual healing in disabled veterans diagnosed with post-traumatic stress disorder (PTSD). Drawing from personal experience, rigorous biblical training, and extensive research, I argue that incorporating faith-based practices and beliefs can complement existing PTSD support and enhance spiritual and mental well-being. Through the lens of generational trauma, the thesis analyzes the complex interplay between individual and collective trauma. It posits that the healing process is intrinsically linked to the restoration of the individual and community. I present a framework for therapeutic photography that incorporates Christian spiritual principles and offers practical guidelines for implementation in conjunction with therapeutic photography. The thesis concludes with a call to action for faith-based communities, mental health practitioners, and policymakers to recognize and address the spiritual and artistic therapeutic needs of disabled veterans with PTSD.
Patient Experience of Cultural Competency in a Hospital Setting
Anthropological research conducted in a local Texas hospital provides data to analyze cultural competency. Increasing health equity is a key aspect of cultural competency literature, hospital, and national goals. Examining the local context allows for the analysis of how one hospital can affect public health in the area by using patient-centered care. Using observational and interview data to create the ideal of the patient journey shows how patient families experience cultural competency. Overall, the patient families felt they experienced culturally competent healthcare, however from the hospital structure perspective there could more goals to attain.
Compositions Designed to Improve Sight Singing in Junior High School
The purpose of this study was to identify certain aspects related to sight singing which tend to cause difficulty in teaching junior high school students and to suggest exercises that might be used to aid in overcoming these difficulties, Data included a questionnaire to junior high school teachers in three states. Subjects researched and discussed were the physical, intellectual, and emotional development of the adolescent; the changing voice and the range and vocal limitations of junior high singers; and rhythmic, melodic, harmonic, and other aspects of sight singing. Included were vocal procedures to be used with young voices, suggestions for choosing and/or arranging appropriate music, and original compositions designed to meet the needs and interests of junior high school students.
Jean Millet's L'Art de bien Chanter (1666): a Translation and Study
Jean Millet's L Art de bien chanter (1666), describes the air de cour and its ornamentation as it existed in France during the first half of the seventeenth century. This work, translated for the first time into English and transcribed into modern notation, and B6nigne de Bacilly's Remarques curieuses sur l'art de bien chanter (1668) are the only detailed treatises explaining vocal ornamentation during this period. To clarify his ornamentation method, Millet introduces terms referring to placement of agrements, though few performers used them. Millet expresses the old style, popular under Louis XIII, and the provincial view. Bacilly's treatise deals with the air de cour under Louis XIV, which had a more Italian flavor. He gives aesthetic principles aiding the performer in placing and selecting ornaments. Though Millet and Bacilly describe the same practice, striking differences exist between the two air de cour styles.
Relationship of Internal-External Locus of Control and Performance in a Weight-Control Program
This study explores the relationship between internal-external locus of control and some characteristics of overweight subjects in a weight-control program in the summer and fall of 1973. Only white, female, over-weight, and obese subjects were used. From this study, it appears that Rotter's I-E concept applies to weight loss. This one significant finding lends support to research that internals control their impulses better than externals and that internals seem to learn and retain relevant information better than externals.
Rickshaw Man
This documentary film tells the story of Mohammad in India, and Mike in the United States, who are separated by social, economic, cultural, linguistic and religious differences, and yet there is an inanimate object that connects them-the rickshaw. The film examines how rickshaw men are viewed and treated by the society they live in and also illuminates the threads of commonality between these two men to show that they are not so different from each other after all.
The Effect of Teacher Approval/Disapproval on Students' On-Task Behaviors in a Selected Beginning Strings Class
The present study explored whether (a) positive or negative reinforcement would produce higher percentages of on-task student behavior at set timed intervals, (b) positive, negative, or total reinforcement would increase student attentiveness after reinforcement, and (c) if natural fluctuations in teacher approval/disapproval would have any bearing on percentages of student attentiveness. Findings of the 15-day study concluded that (a) positive reinforcement maintained significantly higher levels of student attentiveness over negative reinforcement, (b) negative reinforcement did not significantly lower percentages of student attentiveness, and (c) natural fluctuations in rates of teacher approval/disapproval had no apparent effect on the amount of on-task behavior in the beginning strings class.

Estimation of Aircraft Emissions for the Corpus Christi International Airport, Corpus Christi, Texas
Commercial aviation is a vital part of the United States economy. It generates over $1 trillion annually, which is more than 5% of the U.S. GDP, and produces approximately 10 million jobs. Every year there is an increase in commercial air traffic. This is attributed to expanding trade between states and other countries, which requires larger amounts of cargo aircraft in operation, and also catering to the growing number of middle and upper class passengers who travel for business and pleasure purposes. A rise in commercial aviation leads to the use of more aviation fuel on a monthly and annual basis. This in turn leads to escalated levels of combustion by-products from jet and turbofan engines into the atmosphere. The negative effects of these by-products range from producing poor air quality and consequent health hazards to contributing to global warming. This study is aimed at assessing the impacts of aircraft emissions on the local air quality in Corpus Christi using the Emissions and Dispersion Modeling System. Flight data for the study was obtained from the Department of Transportation's Research and Innovative Technology Administration. Analyses of the emissions were compared on monthly, annual, engine type and airline provider bases. Climatic, economic and anthropogenic factors were identified in the analyses.
A-(Substitutedbenzenesulfonyl)-Substitutedacetophenones
This thesis discusses the preparation of a-(o-nitro-p-methylphenylmercapto)-acetophenone by the reaction between acetophenone and o-nitro-p-methylbenzenesulfenyl chloride in boiling chloroform. The use of stannous chloride in glacial acetic acid for the reduction of nitro groups to amino groups was found generally satisfactory in spite of the difficulty often met with in isolating the amino product.
Microstructural Phase Evolution In Laser Deposited Compositionally Graded Titanium Chromium Alloys
A compositionally graded Ti-xCr (10≤x≤30 wt%) alloy has been fabricated using Laser Engineered Net Shaping (LENSTM) to study the microstructural phase evolution along a compositional gradient in both as-deposited and heat treated conditions (1000°C followed by furnace cooling or air cooling). The alloys were characterized by SEM BSE imaging, XRD, EBSD, TEM and micro-hardness measurements to determine processing-structure-property relations. For the as-deposited alloy, α-Ti, β-Ti, and TiCr2 (C15 Laves) phases exist in varying phase fractions, which were influential in determining hardness values. With the furnace cooled alloy, there was more homogeneous nucleation of α phase throughout the sample with a larger phase fraction of TiCr2 resulting in increased hardness values. When compared to the air cooled alloy, there was absence of wide scale nucleation of α phase and formation of ω phase within the β phase due to the quicker cooling from elevated temperature. At lower concentrations of Cr, the kinetics resulted in a diffusionless phase transformation of ω phase with increased hardness and a lower phase fraction of TiCr2. In contrast at higher Cr concentrations, α phase separation reaction occurs where the β phase is spinodally decomposed to Cr solute-lean β1 and solute-rich β2 resulting in reduced hardness.
Voice Onset Time Characteristics of Selected Phonemes in Young and Old Male Speakers
The purpose of the investigation was to compare mean voice onset time in young and old male subjects, as well as to examine variability of VOT productions with age for prevocalic bilabial, alveolar, and velar voiced and voiceless stop consonants. Forty-five Caucasion.males were divided equally into three.age groups. Ten tokens of six stimulus words were recorded and wide band spectrograms were made. Results of an analysis of variance revealed no significant differences in VOT with age when averages of the phonemes were used for analysis; however, a significant interaction between age and voiced phonemes was found when individual trials of phoneme productions were used for analysis.

"It's never been this bad...ever": An analysis of K-12 teachers' standpoints related to parent-teacher communication.
With the rise of "helicopter" parents within primary and secondary education, school officials nationwide have started to address how to manage parental involvement in the educational system, specifically with regard to parent-teacher communication. Beginning in the 1980s, school administrators actively implemented programs targeting increased parental involvement in K-12 public schools, though the use of contact and relationship building strategies, in order to substantiate school-teacher-parent communication and further parental influence over decision making processes. While administrators and parents may view parent-teacher interactions as productive, teachers' negative experiences with parents may lead to stress, burnout, and attrition. Researchers have indicated that between 20 and 50% of first through third year teachers leave the profession due to increased, long-term stress, unrealistic workload, and an overall feeling of decreased personal and professional fulfillment. Likewise, through educational reform initiatives to standardize curriculum and increase parental involvement within public schools, teachers' roles within the educational system have shifted from positions of power, to figureheads for the system. The purpose of this study is to examine public school K-12 teachers' standpoints as they relate to parent-teacher communication.
Students' and Teachers' Perspective of Purposes for Engaging in Physical Activity
Purposes for engaging in physical activities were examined from the perspective of university students enrolled in physical activity classes and kinesiology faculty. Data was collected from 473 students and 20 faculty members. Both groups completed the Personal Purposes and Meanings in Movement Inventory (PPMMI). Independent t-tests were conducted for each of the twenty-two purpose statements to determine differences between faculty and students in the rating of purposes. Students attending individual sport activity classes rated self-knowledge, transcendence, object projection/reception, awareness, competition, neuromuscular efficiency, movement appreciation, and muscular strength significantly lower (p<.01) than the faculty. Students attending team sport activities rated self-knowledge, transcendence, participation, object projection/reception, teamwork, awareness, competition, leadership, and expression significantly (pc.01) lower than the faculty. Students attending fitness activity classes rated self-knowledge, competition, leadership, transcendence, participation, teamwork, circulo-respiratory efficiency, and personal integration significantly (p<.01) lower than faculty.

The Influence of Interactivity and Online Store Atmospherics of a 3-D Retail Store in Second Life on Consumer Purchase Intentions
Second Life, a 3-D virtual world, has evolved as a shopping channel for both consumers and retailers. This channel of retailing offers interactive environment, allows designing atmospherics, and provides enjoyable shopping experience as compared to website stores. The purpose of the study was: (1) to identify the key features of Second Life stores and (2) to determine the relationship of the Second Life store features with consumer purchase intentions. The online survey was administered in Second Life by an external research agency, and 249 usable surveys were collected. The data were analyzed utilizing factor analysis and regression. Three key features of Second Life stores were explored in this study. These three features were: (1) interactivity via the two components of two-way communication and active control, (2) store atmospherics, and (3) shopping enjoyment. Regression analysis showed that shopping enjoyment and two-way communication (i.e., the presence of an avatar sales representative) were significant predictors of purchase intention in Second Life stores, while active control and store atmospherics did not influence purchase intentions.
Longitudinal Prevalence of Disordered Eating and Weight Control Behaviors in Female Collegiate Athletes
Female collegiate athletes have been established as a high-risk group for the development of eating disorders due to the high prevalence rates of clinical and subclinical eating disorders, which have ranged from 1.9% to 16.6% and 4.0% to 26.1%, respectively. Collegiate athletes appear to meet criteria for ED-NOS more often than anorexia or bulimia nervosa, and frequently engage in pathogenic weight control behaviors (e.g., dieting, excessive exercise). To date, only a few studies have examined the long-term stability of eating disorders in collegiate female athletes. The current study investigated the prevalence of eating disorders (i.e., eating disordered, symptomatic, and asymptomatic) and pathogenic weight control behaviors (e.g, binging, vomiting, laxative use) in 325 NCAA-DI female collegiate gymnasts and swimmers/divers across two time points – the beginning of their competitive seasons (Time 1) and during the final two weeks of their competitive seasons (Time 2). By Time 2, 90% of the athletes classified as eating disordered at Time 1 (n = 20) maintained clinical or subclinical eating disturbances. Of the 83 athletes originally symptomatic, 37.3% remained so and 10.8% became eating disordered. Significantly more athletes became satisfied with their bodies over the course of the season than became dissatisfied. The athletes reported using exercise and dieting/fasting as the most frequent forms of weight control behaviors, each of which were used less frequently at Time 2 than at Time 1. The results support overall stability of eating disorder behaviors and classification over the course of a competitive season. Limitations and implications are discussed.

Development, Implementation, and Analysis of a Contact Model for an Infectious Disease
With a growing concern of an infectious diseases spreading in a population, epidemiology is becoming more important for the future of public health. In the past epidemiologist used existing data of an outbreak to help them determine how an infectious disease might spread in the future. Now with computational models, they able to analysis data produced by these models to help with prevention and intervention plans. This paper looks at the design, implementation, and analysis of a computational model based on the interactions of the population between individuals. The design of the working contact model looks closely at the SEIR model used as the foundation and the two timelines of a disease. The implementation of the contact model is reviewed while looking closely at data structures. The analysis of the experiments provide evidence this contact model can be used to help epidemiologist study the spread of an infectious disease based on the contact rate of individuals.

The purpose of this study is to determine sound principles for custodial service in the small school.
The Goals of the Peace Corps
Agencies such as the Peace Corps are by nature benevolent, which means they are devised for the expressed purpose of granting aid to other persons. In this case, the avowed purpose is aid for the underdeveloped nations of the world. However, politicians lodged in governmental authority are not humanistic solely for the sake of helping others; there are political aims to be gained. What these aims are and how they affect the operation of a youth corps for peace is a major concern of this thesis.
Practical Approach to Protestant Church Music
The purpose of this study is to make the Protestant church workers more efficient in their use of music in religious work by giving them a clear conception of the kind of music to be used and by suggesting detailed plans and methods by which desirable results may be secured in the use of church music. Ideal standards have their place, but here it is proposed to be matter-of-fact, practical and concrete, and to secure immediate results with the average church member and choir singer as the final criterion in every phase of the work. The purpose is not to emphasize high ideals but to instruct and inspire all those who have leadership in the service of church music, that they may be able here to provide the greatest religious helpfulness that the use of music can bring the souls to whom they minister.

Shaping Appropriate Verbal Responses in a Social Situation With a Withdrawn Retarded Adolescent
"Shaping" or "method of successive approximation" is a procedure which may be applied to increase the frequency of a response which has a low operant level, or it may also be used to bring about responses which have not been previously emitted. In "shaping," the experimenter initially reinforces a response which is within the behavorial repertoire of the subject. Then, the experimenter reinforces only responses which approximate the behavior which is desired. The final behavior is then directly reinforced.

Reconstruction in Collin County, Texas, 1865-1876
This is a work of local history examining the course of Reconstruction in Collin County, Texas. National and state level surveys of Reconstruction often overlook the experiences of communities in favor of simpler, broader narratives. The work proceeds chronologically, beginning with the close of the Civil War, and tells the story of Collin County as national Reconstruction progressed and relies on works of professional and non-academic historians, oral histories, census data, and newspapers to present a coherent picture of local life, work, and politics. The results exemplify the value of local history, as local conditions influenced the course of events in Collin County as much as those in Austin and Washington D.C. The story of Reconstruction in Collin County is one of anomalous political views resulting from geographical exclusion from the cotton culture of Texas followed by a steady convergence. As Reconstruction progressed, Collin County began to show solidarity with more solidly conservative Texas Counties. The arrival of railroads allowed farmers to move from subsistence agriculture to cash crop production. This further altered local attitudes toward government, labor, voting rights, and education for Freedmen. By the end of Reconstruction, Collin County had all but abandoned their contrarian social and political views of the 1850s and 1860s in favor of limited rights for blacks and Redemption. The results show the importance of local history and how Collin County’s Reconstruction experience enriches and deepens how historians view the years after the Civil War. The author recommends further research of this kind to supplement broader syntheses.
Kinetic Investigation of the Gas Phase Atomic Sulfur and Nitrogen Dioxide Reaction
The kinetics of the reaction of atomic sulfur and nitrogen dioxide have been investigated over the temperature range 298 to 650 K and pressures from 14 - 405 mbar using the laser flash photolysis - resonance fluorescence technique. The overall bimolecular rate expression k (T) = (1.88 ± 0.49) x10-11 exp-(4.14 ± 0.10 kJ mol-1)/RT cm3 molecule-1 s-1 is derived. Ab initio calculations were performed at the CCSD(T)/CBS level of theory and a potential energy surface has been derived. RRKM theory calculations were performed on the system. It is found that an initially formed SNO2 is vibrationally excited and the rate of collisional stabilization is slower than the rate of dissociation to SO + NO products by a factor of 100 - 1000, under the experimental conditions.
