This study used qualitative research, particularly life history analysis, to determine the personal pathways of success for Latino students who chose to enter a health science center for graduate study and who graduated. By giving voice to individual success stories of Latino students, some of the influences on the life pathways of these graduates were determined. For the purposes of this study, success was defined as graduation from a health science center with either a doctor of philosophy, doctor of public health or doctor of osteopathic medicine degree. Four research subjects agreed to participate in this study from a possible 11 students from the graduating class of 2004-2005 at this health science center. Data were gathered through multiple in-depth interviews of the students themselves over a period of no more than one month for each participant. Data were analyzed using the mind mapping technique and Padilla's unfolding matrix. Findings indicate that each participant traveled a different pathway to achieve educational success although similarities did exist across participants. The influences of family background, cultural background, educational background and personal perceptions and goals did affect the pathways of these four Latino graduates. While three of four participants indicated that family was the …

Let 1, 2, 3, 5, 8, … denote the Fibonacci sequence beginning with 1 and 2, and then setting each subsequent number to the sum of the two previous ones. Every positive integer n can be expressed as a sum of distinct Fibonacci numbers in one or more ways. Setting R(n) to be the number of ways n can be written as a sum of distinct Fibonacci numbers, we exhibit certain regularity properties of R(n), one of which is connected to the Euler φ-function. In addition, using a theorem of Fine and Wilf, we give a formula for R(n) in terms of binomial coefficients modulo two.

Numerous enzymatic reactions are controlled by the chemistry of metallic ions. This dissertation investigates the electronic properties of three transition metal (copper, chromium, and nickel) complexes and describes modeling studies performed on glutathione synthetase. (1) Copper nitrene complexes were computationally characterized, as these complexes have yet to be experimentally isolated. (2) Multireference calculations were carried out on a symmetric C2v chromium dimer derived from the crystal structure of the [(tBu3SiO)Cr(µ-OSitBu3)]2 complex. (3) The T-shaped geometry of a three-coordinate β-diketiminate nickel(I) complex with a CO ligand was compared and contrasted with isoelectronic and isosteric copper(II) complexes. (4) Glutathione synthetase (GS), an enzyme that belongs to the ATP-grasp superfamily, catalyzes the (Mg, ATP)-dependent biosynthesis of glutathione (GSH) from γ-glutamylcysteine and glycine. The free and reactant forms of human GS (wild-type and glycine mutants) were modeled computationally by employing molecular dynamics simulations, as these currently have not been structurally characterized.

This is an historical study of an institution of higher education that existed in St. Augustine, Florida from 1942-1949. The name of the institution was The University Foundation, founded by George J. Apel, Jr. This institution had several higher education divisions functioning under its umbrella. These divisions were the St. Augustine Junior College, the Graduate Division, the American Theological Seminary and the University Extension College with evening courses and Home Study courses for vacation study. The information collected for this study was accomplished primarily by the process of studying archives and conducting personal interviews. Since this is a qualitative research study, the collected information was processed through the use of multiple data-collection methods, data sources and analyses which insured the validity of the findings of the study. This process is known as information triangulation. The results of this study provide answers to the circumstances and identities of the key players which led to the formation of The University Foundation. Issues relating to the mission, revenue streams, faculty, curricula, and the ultimate demise of The University Foundation were also addressed in this study. Recommendations are included for higher education administrators, faculty, researchers, fund-raisers, and others whose efforts may be directed toward …

The need to establish appropriate, adequate, and decent educational facilities for school children across the nation has been well-established. The ability of school districts in each state to build these facilities has varied widely in the past. Historically, most facilities funding ability for school districts has come from the local community and has been tied to property wealth and the ability of the community to raise significant tax dollars to pay for school buildings. Responding to an expanding need for increased facilities funding and school funding litigation, the state of Texas added facilities funding mechanisms for public school facilities construction in the late 1990s. The purpose of this study was to determine whether or not the methods of facilities funding were equitable in the state of Texas. In this study, equity values were framed around three equity concepts established in school funding equity literature. These three concepts were (1) horizontal equity defined as the equal treatment of equals, (2) vertical equity defined as the unequal treatment of unequals, and (3) wealth neutrality defined as the absence of a relationship between school district wealth and the equal opportunity of students. The sample comprised 1,039 school districts in the state of Texas. …

This lecture recital seeks to prove that Sergei Taneyev's only piano concerto is a valuable addition to the piano concerto repertoire for historical and theoretical examination. Taneyev's biographical background proves he was one of the major figures in Russian musical life during the late nineteenth century. For one who had such an important role in music history, it is an unfortunate that his music has not been popular. Through letters to contemporary composers and friends, Taneyev's master teacher Tchaikovsky revealed why his music and piano concerto were not as popular as they should have been. This lecture recital examines Taneyev's compositional style and illustrates his influence in the works of his famous student Sergei Rachmaninoff through examples from Taneyev's Piano Concerto in E-flat Major and Rachmaninoff's Piano Concerto No. 2. Taneyev's Piano Concerto and Tchaikovsky's Piano Concerto No. 1 have both similarities and differences that resulted from the composers' close relationship. Letters between the teacher and student enlighten readers to the compositional process of the two piano concertos and demonstrates the value of Taneyev's Piano Concerto. A detailed theoretical analysis is included in this dissertation. The principal themes and motifs are presented with a detailed analysis of the structure of …

Among the commercial aluminum alloys, aluminum 319 (Al-7wt%Si-4wt%Cu) type alloys are popularly used in automobile engine parts. These alloys have good casting characteristics and excellent mechanical properties resulting from a suitable heat treatment. To get a high strength in the 319 type alloys, grain refining, reducing the porosity, solid solution hardening, and precipitation hardening are preferred. All experimental variables such as solidification condition, composition, and heat treatment are influence on the precipitation behavior; however, precipitation hardening is the most significant because excess alloying elements from supersaturated solid solution form fine particles which act as obstacles to dislocation movement. The challenges of the 319 type alloys arise due to small size of precipitate and complex aging response caused by multi components. It is important to determine the chemical composition, crystal structure, and orientation relationship as well as precipitate morphology in order to understand the precipitation behavior and strengthening mechanism. In this study, the mechanical properties and microstructure were investigated using transmission electron microscopy and three dimensional atom probe tomography. The Mn and Mg effects on the microstructure and mechanical properties are discussed with crystallographic study on the iron intermetallic phases. The microstructural evolution and nucleation study on the precipitates in the …

This dissertation examined the impact of Medicare Plan D on medication compliance in Medicare beneficiaries at University of Texas Health Center at Tyler, TX. Data were collected before and after the implementation of Plan D. The impacts of various types of benefits, such as private insurance, employer insurance and pharmacy assistance programs were evaluated in terms of impact on drug compliance. Medication compliance was found to increase in those respondents without Plan D. Plan D was found to be a predictor of those who spent less on basics in order to buy medications. Although compliance increased in general, these increases could not be attributed to the acquisition of a Plan D policy.

Reality TV is the most popular genre of television programming today. The number of reality television shows has grown exponentially over the last fifteen years since the premier of The Real World in 1992. Although reality TV uses styles similar to those used in documentary film, the “reality” of the shows is questioned by critics and viewers alike. The current study focuses on the “reality” that is presented to viewers and how that “reality” is created and may differ from what the participants of the shows experience. I appeared on two reality shows, Faking It and That's Clever, and learned a great deal as a participant observer. Within the study, I outline my experience and demonstrate how editing changed the reality I experienced into what was presented to the viewers. O'Connor's (1996) representation context web serves as a model for the realities created through reality television. People derive various benefits from watching reality TV. Besides the obvious entertainment value of reality TV, viewers also gather information via this type of programming. Viewers want to see real people on television reacting to unusual circumstances without the use of scripts. By surveying reality TV show viewers and participants, this study gives insight …

The interaction among firms in the supply chain is necessary for business process execution and relationship success. One phenomenon of great significance to buyer-supplier relationships is opportunism. Opportunism is defined as behavior that is self-interest seeking with guile. It is manifested in behaviors such as stealing, cheating, dishonesty, and withholding information. Opportunism negatively impacts relational exchange tenets such as trust, commitment, cooperation, and satisfaction. Furthermore, perceptions of opportunism negatively affect firm performance. In lieu of the known negative effects of opportunistic behavior on buyer-supplier relationships, why do agents continue to engage in opportunistic tactics with their exchange partners? A comprehensive examination is necessary in order to understand why sourcing professionals engage in acts of opportunism. Understanding why opportunism occurs will reveal how to deter it, and this remains a gap in the literature. Based on theories in economics, marketing channels, supply chain management, decision science, and psychology, a comprehensive model tested a set of factors hypothesized to drive the use of opportunistic tactics. Factors include buyer-supplier relationship-specific factors, environmental factors, individual personality-related factors, and situational factors. Data was collected via internet survey of sourcing professionals from private industry and government agencies. Common to many studies of ethics, respondents made choices …

The two major research questions were: “What is the current status of 20 prominent piano pedagogy programs?” and “what is the vision of an ideal future piano pedagogy program from the perspective of 20 piano pedagogy leaders?” Subjects were the leaders of the top 20 US university piano pedagogy programs. A survey study with interview questions was used as the instrument for the study. The results showed that faculty, curriculum, and teacher training were three top factors that contributed to the quality of the programs. Most interviewed subjects held a doctoral degree in music. The curricular content and degree options were diverse across the selected programs. The content of teacher training included private and group teaching. The perceived best qualifications of a piano pedagogy instructor were to have a balanced education. Most programs had small or little to no budget, however, the preparatory program was perceived to be an enhancement to teacher training program finances. The greatest challenges were faculty acquisition and financial limitations. Gaining more money was the most common improvement priority for programs. To envision an ideal future piano pedagogy program, most leaders stated that an ideal program should contain encourage: (1) collaborating with other divisions' faculty members …

The present study was a retrospective chart review (N=128) that investigated the efficacy of profiles derived from the three factors of the Eating Inventory® test (EI) - cognitive restraint, disinhibition, and hunger - to predict successful weight loss in post surgical laparoscopic banding patients at 6 and 9 months post surgery. Although the EI is commonly used in bariatric presurgical assessment, few studies have found consistent relationships between presurgical factor scores and subsequent weight loss in this population. Based on restraint theory, 7 profiles (high CR, super high CR, high D, super high D, high H, super high H, and null) were derived from the raw scores on the subscales of the EI and tested for weight loss predictive ability using direct logistic regression. Results were mixed with high CR, super high CR, and null profiles accurately predicting successful weight loss. Raw scores on the three factors (cognitive restraint, disinhibition, and hunger) were tested individually for predictive ability using direct logistic regression. Overall results indicated that the profile model accurately predicted more cases than the general factor model. This study significantly contributes to both the bariatric presurgical assessment literature and the restraint theory literature. Suggestions for future research are offered.

Balakirev's two early piano and orchestra works, Grande Fantaisie on Russian Folk Songs and Concerto Op. 1 in F# Minor, were composed in the middle of the nineteenth century when in Russia there were no particularly important works for piano and orchestra. Balakirev was still a teenager when he wrote these two pieces and unfortunately both remained unfinished. However the beauty and remarkable compositional achievement of these works should be highly recognized. There are six chapters in this essay. The general background, purpose and the state of research are discussed in the first chapter. The second chapter presents Balakirev's biographical information and the overview of his works for piano and orchestra is stated in Chapter III. Individual works, Grande Fantaisie and Concerto in F# Minor are discussed in the chapters IV and V, which including discussing compositional background, analysis and diagram of structural schemes. The last chapter concludes with Balakirev's contribution to Russian music and the development of the Russian concerto coming into its own. It deals particularly with Balakirev's approach to folk songs, which gives the concerto a unique Russian aesthetic, in addition to his ability to write in the European tradition.

The aspiration of this dissertation is to bring forth the significance of Shostakovich's Piano Sonata Op.12. This sonata is a hybrid of the German musical tradition, Russian Modernism, and Liszt's thematic transformation technique. It demonstrates Shostakovich's highly intellectual compositional skills influenced by the education that he received at St. Petersburg Conservatory as well as the exposure to modern music in the 1920s. This dissertation discusses composition techniques, such as the harmonic piers adapted from Alexander Scriabin, neighboring-tone technique, which involves the application of semitone cell throughout the piece, as well as the technique of thematic transformation borrowed from Liszt. These all come together by Shostakovich's design in the most controversial sonata form. The Piano Sonata Op.12 also sheds light on Shostakovich's early compositional style and proves its contribution to the evolution of sonata genre in the twentieth-century.

The Octuor pour instruments a vents (or Octet), written in 1922-1923 by Igor Stravinsky, is a piece in three movements for a curious assortment of instruments: two trumpets, two trombones, flute, clarinet and two bassoons. It is one of four influential chamber works for winds by Stravinsky to include trumpet. Of these pieces, the Octet contains the fewest number of players but is no less complex and important in Stravinsky's oeuvre. The Octet helped mark the beginning of the neoclassical period in twentieth-century music. Chapter 2 examines the life and musical background of the composer. It also reveals the history surrounding the origin of the Octet and its role in neoclassicism. Chapter 3 discusses the role of the Octet in the wind ensemble and orchestral repertoire, and includes a representative performance history, including the premiere. Chapter 4 provides analytical insights into the construction and format of the piece. Chapter 5 provides suggestions regarding style in Stravinsky's music, including interviews with important figures in the trumpet world. Chapter 6 concludes the guide with specific suggestions regarding preparation and performance of the Octet.

The purpose of this study was to conduct a survey to identify the beliefs and practices of conservative Protestant parents, which assisted in clarifying the assertions in the current literature regarding conservative Protestant parenting. Additionally, this researcher sought to determine the applicability of child parent relationship therapy (CPRT), a filial therapy model based upon the principles of child centered play therapy, for conservative Protestant parents by ascertaining the need for cultural modifications. Beliefs and practices of conservative Protestants were measured using the Protestant Parenting Inventory (PPI), an original instrument developed through a series of focus groups and pilot testings. The population comprised 148 mothers and fathers from 4 Southern Baptist churches in and around the Dallas/Fort Worth metroplex. Exploratory factor analysis was applied to the data in order to increase internal consistency estimates and percent of explained variance. Criterion coding of demographic data allowed a multiple regression analysis to determine which demographic variables were significant predictors of participant responses on the PPI. Descriptive statistics allowed the researcher to investigate the compatibility of conservative Protestants and CPRT. Results of this study both confirm and refute past findings regarding conservative Protestants. Results also revealed the need for some cultural modifications to CPRT …

This study was designed to determine the effects of two different schedule types on mathematics achievement in public high school students. The instruments used included the Texas Assessment of Knowledge and Skills, given annually to all students in grades 3 through 11, the Texas Algebra I end-of-course examination, given as a district option to Algebra I students, and student final course grades as determined by classroom teachers. The study compared students' performance in these three areas during the 2004-2005 academic year in one suburban school district in North Texas. The study considers the type of schedule, either traditional or 8-block, between students in teachers' classes who teach the same course on both schedules concurrently. This study also investigates a qualitative aspect by including a short opinion survey of teachers' perceptions regarding student academic performance, teacher satisfaction and retention, and the ability to accomplish curricular goals. Findings from this research suggest course schedule does not have significant effects on student academic performance as measured using analyses of covariance comparisons with a 0.05 alpha-level, leading to the conclusion that a particular course schedule does not adversely impact student performance on academic measures. However, in some comparisons conducted within the course of the …

The presence of deposits on the secondary side of pressurized water reactor (PWR) steam generator systems is one of the main contributors to the high maintenance costs of these generators. Formation and transport of corrosion products formed due to the presence of impurities, metals and metallic oxides in the secondary side of the steam generator units result in formation of deposits. This research deals with understanding the deposit formation and characterization of deposits by studying the samples collected from different units in secondary side system at Comanche Peak Steam Electric Station (CPSES). Fourier transform infrared spectrophotometry (FTIR), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) have been used for studying the phases, morphologies and compositions of the iron oxides formed at Unit 1 and Unit 2 of secondary side of steamgenerator systems. Hematite and magnetite were found to be the dominant phases of iron oxides present in the units. Fe, Cr, O, Ni, Si, Cl and Cu were found in samples collected from both the units. A qualitative method was developed to differentiate iron oxides using laser induced breakdown spectroscopy (LIBS) based on temporal response of iron oxides to a high power laser beam. A quantitative FTIR technique was …

The state of Texas passed the Student Success Initiative (SSI) in 1999 which requires all 3rd graders to pass the reading portion of the Texas Assessment of Knowledge and Skills (TAKS) test to be promoted to the 4th grade, and for 5th graders to pass the reading and math portions of the TAKS test to be promoted to the 6th grade. Beginning in spring 2008, 8th graders will also need to pass the reading and math portions of the TAKS test to be promoted to the 9th grade. The purpose of this study was to examine the academic performance of 3rd and 5th grade students who did not meet the passing standard on the TAKS test and were retained during the 2005-2006 school year. The population of this study included 33 3rd graders and 49 5th graders who were retained during the 2005-2006 school year due to not meeting the promotion requirements of the SSI. There was also a second population of 49 5th graders who were retained in 3rd grade during the 2003-2004 school year due to not meeting the promotion requirements of the SSI. These students were enrolled in the 5th grade for the first time during the …

In recent years scholars have begun to re-evaluate the works, writings, and life of Robert Schumann (1810-1856). One of the primary issues in this ongoing re-evaluation is a reassessment of the composer's late works (roughly defined as those written after 1845). Until recently, the last eight years of Schumann's creative life and the works he composed at that time either have been ignored or critiqued under an image of an illness that had caused periodic breakdowns. Schumann's late works show how his culture and the artists communicating within that culture were transformed from the beginning to the middle of the nineteenth century. These late works, therefore, should be viewed in the context of Schumann's output as a whole and in regard to their contributions to nineteenth-century society. Schumann's contributions, specifically to the genre of the song cycle from 1849 to 1852, are among his late compositional works that still await full reconsideration. A topical study, focusing on three themes of selections from his twenty-three late cycles, will provide a critical evaluation of Schumann's compositional output in the genre of the song cycle. First, Schumann's political voice will be examined. The political events that led to the mid-nineteenth-century revolutions inspired crucial …

Layered double hydroxides (LDH) have been principally known as anion-exchanging, clay-like materials for several decades, and continues to be the main driving force for current and future research. The chemical interactions of LDH, with transition metallocyanides, have been a popular topic of investigation for many years, partly due to the use of powder x-ray diffraction and infrared spectroscopy as the main characterization tools. Each transition metallocyanide has a characteristic infrared stretching frequency that can be easily observed, and their respective sizes can be observed while intercalated within the interlayer of the LDH. The ability of LDH to incorporate metal cations or any ions/molecules/complexes, that have a postive charge, have not been previously investigated, mainly due to the chemical and physical nature of LDH. The possibility of cationic incorporation with LDH would most likely occur by surface adsorption, lattice metal replacement, or by intercalation into the LDH interlayers. Although infrared spectroscopy finds it main use through the identification of the anions incorporated with LDH, it can also be used to study and identify the various active and inactive bending and stretching modes that the metal hydroxide layers have.

Admissions processes for health professions programs result in students entering these programs academically homogeneous. Yet some students have great difficulty with the programs. Research has shown a limited ability of traditional academic indicators to predict successful outcomes for health professions education. The purpose of this study was to examine the relationship between learning motivation and academic outcomes for students in health professions programs. The Modified Archer Health Professions Motivation Scale (MAHPMS) and a demographic survey were administered at orientation to 131 medical and 29 physician assistant students at the University of North Texas Health Science Center in the fall of 2005. At the end of the semester, the same version of the MAHPMS was administered, and final course grades and semester averages were collected. Descriptive statistics were analyzed for all the study variables. Analysis of variance was utilized to examine within subjects and between subjects differences for the learning motivation scores among programs and demographic categories. Linear regression analyses were used to determine the relationship between learning motivation scores and end-of-semester grades. And finally, logistic regression was performed to explore the ability of the motivation scores to predict academically high-risk students. Approximately three-fourths of the students indicated a preference for …

This study examined the current status of schoolwide positive behavior support efforts in Texas. The study specifically (a) examined the impact of statewide positive behavior interventions and supports (PBIS) training on the rates of discipline records, in-school ¬suspensions, out-¬of¬-school suspensions, disciplinary alternative education placements, and expulsions of public schools in Texas; (b) investigated the overall effectiveness of schoolwide positive behavior support; and (c) determined the differences between rates of discipline records, in-school ¬suspensions, out-¬of¬-school suspensions, disciplinary alternative education placements, and expulsions in schools participating in the Texas Behavior Support Initiative (TBSI): Schoolwide PBS Project when compared with matching schools who did not participate in the project. This study demonstrated that schools can significantly reduce problem behavior in their schools when implementing PBIS with fidelity. Creating effective systems of PBIS required training, coaching, and on¬site technical assistance by trained and experienced PBIS facilitators.

In 2005, composer Susan Botti won the coveted Prix de Rome in musical composition and spent eleven months in residency at the American Academy in Rome. That same year, the University of Michigan Wind Symphony, under the direction of Michael Haithcock, premiered her exciting new work Cosmosis at the College Band Directors National Association Conference in New York City. The bi-annual conference is a venue for the premiere of new works for wind ensembles and bands, and the 2005 conference saw the world premiere of nine works for winds and percussion, many of which were performed in the legendary Carnegie Hall. What made the debut performance of Cosmosis exciting and notable was the composer's own appearance as soprano soloist, and the inclusion of a chorus of women augmenting the ensemble of winds and percussion. Such a combination of elements is unique, and created a fresh and powerful sonority. Botti's inventive approach to composition has expanded the repertoire for both women's chorus and wind ensemble with this distinctive work. This study is intended to serve as a guide to the study and performance of Cosmosis. The information provides a detailed examination of the work from its conception to its premiere performance. …
