Mass for AILM by Geonyong Lee: The Composer and the Elements of Asian Music (open access)

Mass for AILM by Geonyong Lee: The Composer and the Elements of Asian Music

Geonyong Lee, the composer of Mass for AILM, is a well-known composer in Asia whose main interest lies in choral music. He has composed numerous choral works which are highly diverse in their nature. This study introduces the choral composer Geonyong Lee to the West. The significance of Geonyong Lee's Mass for AILM is the display of Asian inflection in a traditional setting of the mass ordinary. Lee's Mass for AILM employs melodic and rhythmic aspects of traditional Philippine folk songs, a Japanese mode, traditional Korean music, and various Asian percussion instruments. This study explicates these Asian influences and how Lee utilized them in his Mass for AILM.

Development of a proposed toddler caregiver training program for South Korea. (open access)

Development of a proposed toddler caregiver training program for South Korea.

Based on the survey results of 150 South Korea toddler caregivers about training needs, I developed a relationship-based approach for a toddler caregiver training program. The training program was modified using suggestions provided by 6 South Korean professors, who were asked to review the program. Survey findings revealed that: (a) All participants (toddler caregivers) perceived that it is necessary for caregivers to attend training. However, most (72.2%) found that it was difficult to attend training programs more than 1 time per year because it was hard to find a substitute teacher (64%). Participants desired to attend training programs on toddler care because of the lack of in-service education (26%), curriculum (24%), and training programs (15.3%); (b) Caregivers who had the third-degree caregiver certification preferred to learn parent education more than child development. However, caregivers who had a higher degree of caregiver certification preferred to learn child development more than parent education; and (c) Caregivers who had more than 5 years of teaching experience preferred to learn about the teacher's role more than caregivers who had fewer than 4 years of teaching experience. Future studies need to evaluate the effect of this relationship-based training program for toddler caregivers in relation to …

British Prime Minister Tony Blair's Decision to Go to War in Iraq: An Evaluation of Motivating Factors (open access)

British Prime Minister Tony Blair's Decision to Go to War in Iraq: An Evaluation of Motivating Factors

Blair sent British troops to join U.S. forces in the invasion of Iraq in 2003 at great political cost to himself. What motivated him to take this step? Sources for this work include: autobiographies and biographies of individuals close to Blair; journal and newspaper articles and monographs on this topic; Prime Minister's speeches and press conferences. Part one is comprised of five chapters including the Introduction; Blair's years at school; Blair's early political career; and From Parliament to Prime Minister. Part two includes four chapters that analyze motivating factors such as, Anglo-American Relations; Blair's personality, faith, and his relationship with Gordon Brown; and finally, Blair's perception of Britain's Manifest Destiny. All of these factors played a role in Blair's decision.

The Museum of Coming Apart (open access)

The Museum of Coming Apart

This dissertation comprises two parts: Part I, which discusses use of second person pronoun in contemporary American poetry; and Part II, The Museum of Coming Apart, which is a collection of poems. As confessional verse became a dominant mode in American poetry in the late 1950s and early 60s, so too did the use of the first-person pronoun. Due in part to the excesses of later confessionalism, however, many contemporary poets hesitate to use first person for fear that their work might be read as autobiography. The poetry of the 1990s and early 2000s has thus been characterized by distance, dissociation, and fracture as poets attempt to remove themselves from the overtly emotional and intimate style of the confessionals. However, other contemporary poets have sought to straddle the line between the earnestness and linearity of confessionalism and the intellectually playful yet emotionally detached poetry of the moment. One method for striking this balance is to employ the second person pronoun. Because "you" in English is ambiguous, it allows the poet to toy with the level of distance in a poem and create evolving relationships between the speaker and reader. Through the analysis of poems by C. Dale Young, Paul Guest, …

Benjamin Britten's Sonata in C for Cello and Piano, Op. 65: A Practical Guide for Performance (open access)

Benjamin Britten's Sonata in C for Cello and Piano, Op. 65: A Practical Guide for Performance

Benjamin Britten is a renowned and prolific English composer, well known for his operas and vocal works. He did, however, also compose five works especially for the cello as a solo instrument of which the Sonata in C for Cello and Piano Op. 65 was the first. He was inspired by one of his musical contemporaries, the remarkable Soviet cellist, Mstislav Rostropovich. Rostropovich was famous for his amazing artistry which propelled him to become one of the most prominent cellists in the world during his time. Thus Britten, who had previously only composed for cello as part of ensembles, created this sonata specifically thinking of Rostropovich and his outstanding skill as a cellist. The premiere of the sonata took place in July 1961 at the Aldeburgh Festival and it was a great success. However, despite Britten's reputation as an outstanding composer and the significance of the sonata, this sonata has been performed infrequently. Britten utilized many challenging techniques and adapted them innovatively in the composition, and perhaps performers may be reluctant to choose this work due to the complexity and challenge inherent in the composition itself. The purpose of this dissertation is to provide a practical guide for students and …

An Attempt to Dissociate Effects of Response Requirements and Sample Duration in Conditional Discrimination Learning with Pigeons. (open access)

An Attempt to Dissociate Effects of Response Requirements and Sample Duration in Conditional Discrimination Learning with Pigeons.

Attempts to control various aspects of response requirements and sample viewing durations of sample stimuli show that an increase in both facilitates acquisition of conditional discriminations. Despite these attempts, few empirical data exist that demonstrate the relative contributions of both response- and time-dependent schedules. In addition, viewing opportunities of sample stimuli are present outside of the researchers' control, allowing for 'unauthorized sample viewing.' This study employed a titrating delay matching-to-sample procedure to systematically control various aspects of response requirements and sample viewing durations to independently assess their relative contributions towards conditional discrimination performance. Four pigeons worked on a titrating delay matching-to-sample procedure in which the delay between sample offset and comparison onset continuously adjusted as a function of the accuracy of the pigeons' choices. Results show sample viewing durations contribute most toward conditional discrimination performance. The data show 'unauthorized sample viewing' improved acquisition of conditional discriminations and should be a consideration in design of future research.

Development of a Real-time Pcr Assay for the Detection of Campylobacter Jejuni and Campylobacter Coli. (open access)

Development of a Real-time Pcr Assay for the Detection of Campylobacter Jejuni and Campylobacter Coli.

Campylobacter organisms are the most commonly reported bacterial causes of foodborne infection in the world, with Campylobacter jejuni and Campylobacter coli responsible for over 99% of reported infections. Traditionally, Campylobacter species detection is an arduous process, requiring a special incubation environment as well as specific growth media for an extended growth period. The development of a rapid and reliable diagnostic tool for the detection of Campylobacter species would be a valuable aid to the medical diagnostic decision process, especially to rule out Campylobacter infection during the enteric pre-surgical time period. Improved patient outcomes would result if this rapid assay could reduce the number of enteric surgeries. Assays performed during this dissertation project have demonstrated that both SYBR® green and hydrolysis probe assays targeting an 84 nucleotide portion of cadF, a fibronectin-binding gene of Campylobacter jejuni and Campylobacter coli, were able to detect from 101 to 108 copies of organism from stool specimens, did not detect nonspecific targets, and exhibited a coefficient of variation (CV) of 1.1% or less. Analytical validation of sensitivity, specificity and precision, successfully performed in these studies, warrants additional clinical validation of these assays.

A Comparison of Ferruccio Busoni's Two Original Piano Compositions, Indianische Fantasie for Piano and Orchestra, Op.44, and Indianisches Tagebuch Book I. (open access)

A Comparison of Ferruccio Busoni's Two Original Piano Compositions, Indianische Fantasie for Piano and Orchestra, Op.44, and Indianisches Tagebuch Book I.

This study compares Busoni's two original piano compositions, Indianische Fantasie for piano and orchestra (Indian Fantasy), op.44, and Indianisches Tagebuch (Indian Diary) Book I. They represent Busoni's late period of maturity and new aesthetical points of view on music. Both pieces are originated from Natalie Curtis's The Indian's Book, and particularly the Indian Diary is very closely related to the Fantasy, for three of the four pieces in the former work directly quote sections from the latter. To provide clear understanding of the composer's intention in creating two different versions from the same origin, this research examines how Busoni demonstrates his aesthetical ideas of new music in these two Indian piano compositions throughout structural and formal analysis. Busoni's adaption of Indian folk song in these works for the piano aimed at integrating Indian folk element with his personal harmonic language, both of which emphasized freedom in nature.

Cross Language Information Retrieval for Languages with Scarce Resources (open access)

Cross Language Information Retrieval for Languages with Scarce Resources

Our generation has experienced one of the most dramatic changes in how society communicates. Today, we have online information on almost any imaginable topic. However, most of this information is available in only a few dozen languages. In this thesis, I explore the use of parallel texts to enable cross-language information retrieval (CLIR) for languages with scarce resources. To build the parallel text I use the Bible. I evaluate different variables and their impact on the resulting CLIR system, specifically: (1) the CLIR results when using different amounts of parallel text; (2) the role of paraphrasing on the quality of the CLIR output; (3) the impact on accuracy when translating the query versus translating the collection of documents; and finally (4) how the results are affected by the use of different dialects. The results show that all these variables have a direct impact on the quality of the CLIR system.

The Sounds of the Dystopian Future:  Music for Science Fiction Films of the New Hollywood Era, 1966-1976 (open access)

The Sounds of the Dystopian Future: Music for Science Fiction Films of the New Hollywood Era, 1966-1976

From 1966 to1976, science fiction films tended to depict civilizations of the future that had become intrinsically antagonistic to their inhabitants as a result of some internal or external cataclysm. This dystopian turn in science fiction films, following a similar move in science fiction literature, reflected concerns about social and ecological changes occurring during the late 1960s and early 1970s and their future implications. In these films, "dystopian" conditions are indicated as such by music incorporating distinctly modernist sounds and techniques reminiscent of twentieth-century concert works that abandon the common practice. In contrast, music associated with the protagonists is generally more accessible, often using common practice harmonies and traditional instrumentation. These films appeared during a period referred to as the "New Hollywood," which saw younger American filmmakers responding to developments in European cinema, notably the French New Wave. New Hollywood filmmakers treated their films as cinematic "statements" reflecting the filmmaker's artistic vision. Often, this encouraged an idiosyncratic use of music to enhance the perceived artistic nature of their films. This study examines the scores of ten science fiction films produced between 1966 and 1976: Fahrenheit 451, Planet of the Apes, 2001: A Space Odyssey, THX-1138, A Clockwork Orange, Silent Running, …

Readiness scores as indicators of online faculty satisfaction. (open access)

Readiness scores as indicators of online faculty satisfaction.

The purpose of this study was to determine the relationships between online readiness scores and online faculty job satisfaction. Online readiness was assessed using the Readiness for Education At a Distance Indicator (READI) assessment. The READI assessment tool incorporated the independent variables of learning preference, technical competency, technical knowledge, personal attributes, on-screen reading speed and comprehension, and typing speed and accuracy. Online faculty job satisfaction was assessed using the National Study of Postsecondary Faculty (NSOPF) job satisfaction questions. Analysis of variance was used to determine whether there was a difference in satisfaction based on individual instructor learning preferences. Correlation coefficients were used to analyze the relationships between the remaining independent variables and online instructor satisfaction. The sample population (N=110) consisted of online faculty members at Tarrant County College. Most of the statistical analyses revealed non-significant results at the .05 alpha level. However, a significant difference in satisfaction with equipment and facilities was found based on instructor learning preference. Additionally, a statistically significant negative correlation was found between online instructor technical competency and satisfaction with benefits.

FISA and warrantless wire-tapping: Does FISA conform to Fourth Amendment standards? (open access)

FISA and warrantless wire-tapping: Does FISA conform to Fourth Amendment standards?

Electronic surveillance for foreign intelligence purposes was largely unregulated prior to 1978. The Foreign Intelligence Surveillance Act of 1978 (hereinafter "FISA") was enacted to implement a judicial authorization process for foreign intelligence electronic surveillance that would effectively balance competing needs for national security and civil liberty under the Fourth Amendment. This study examines the evolution of FISA and its effectiveness under the Fourth Amendment, as assessed by federal reviewing courts and scholars since the statute's enactment. The study concludes that the FISA electronic surveillance authorization process has been effective in providing a constitutional mechanism to obtain foreign intelligence information.

"A Tale of Two Weapons": Late Holocene Hunting Technology in North Central Texas (open access)

"A Tale of Two Weapons": Late Holocene Hunting Technology in North Central Texas

This research is an investigation of the Late Holocene technological transition from the spearthrower and dart to the bow and arrow in north central Texas. It is conducted through a theoretical approach that utilizes ethnographic research, experimental archaeology and the archaeological record to elucidate differences in the behaviors and hunting strategies of Late Archaic and Late Prehistoric groups. It first confirms that there was a transition. Second, a lithic analysis demonstrates that there are fundamental differences in the sizes of the stone dart and arrow points that relate to the propulsive requirements of the weapon systems. Third, it is shown these size differences constrain maintenance potentials and that indeed dart and arrow points exhibit stark differences in their life histories in spite of being employed for the same task. And finally, the faunal record suggests that this transition was associated with an increase in foraging efficiency.

Predicting Chemical and Biochemical Properties Using the Abraham General Solvation Model (open access)

Predicting Chemical and Biochemical Properties Using the Abraham General Solvation Model

Several studies were done to illustrate the versatillity of the Abraham model in mathematically describing the various solute-solvent interactions found in a wide range of different chemical and biological systems. The first study focused on using the solvation model to construct mathematical correlations describing the minimum inhibitory concentration of organic compounds for growth inhibition towards the three bacterial strains Porphyromonas gingivalis, Selenomonas artemidis, and Streptococcus sobrinus. The next several studies expand the practicallity of the Abraham model by predicting free energies of partition in chemical systems. The free energy studies expand the use of the Abraham model to other temperatures and properties by developing correlations for the enthalpies of solvation of gaseous solutes of various compounds dissolved in water, 1-octanol, hexane, heptane, hexadecane, cyclohexane, benzene, toluene, carbon tetrachloride, chloroform, methanol, ethanol, 1-butanol, propylene carbonate, dimethyl sulfoxide, 1,2-dichloroethane, N,N-dimethylformamide, tert-butanol, dibutyl ether, ethyl acetate, acetonitrile, and acetone. Also, a generic equation for linear alkanes is created for use when individual datasets are small. The prediction of enthalpies of solvation is furthered by modifying the Abraham model so that experimental data measured at different temperatures can be included into a single correlation expression. The temperature dependence is directly included in the model …

The Financial History of the War of 1812 (open access)

The Financial History of the War of 1812

The War of 1812 brought daunting financial challenges to the national government of the United States. At the onset of war, policymakers were still in the process of sifting through a developing body of American economic thought while contemplating the practicalities of banking and public finance. The young nation's wartime experience encompassed the travails of incompetent and cautious leadership, the incautious optimism that stemmed from several previous years of economic growth, the inadequacies of the banking system, and, ultimately, the temporary deterioration of the financial position of the United States. While not equivalent to great tragedy, the war did force Americans to attend to the financial infrastructure of the country and reevaluate what kinds of institutions were truly necessary. This study of the financing of the War of 1812 provides a greater understanding of how the early American economy functioned and the sources of its economic progress during that era. Financial studies have typically not been a primary focus of historians, and certainly with regard to the War of 1812, it is easy to understand a preoccupation with political and military affairs. To a large degree, however, economic realities and financial infrastructure determine a nation's capacity for growth and change …

James Rosenquist: Process, Representation, and the Simulacrum (open access)

James Rosenquist: Process, Representation, and the Simulacrum

American artist James Rosenquist is best known for his Pop Art paintings, which existing scholarship has studied in regard to its formal features and social and cultural significance. Rosenquist's manner of working, specifically his process, remains understudied. Focusing on three paintings and three corresponding collages, President Elect (1960-61, 1964), Star Thief (1980), and The Stowaway Peers Out at the Speed of Light (2000), this thesis considers features of Rosenquist's studio practice to propose a new interpretation involving the representational status and significance of the artist's collages and paintings that is elucidated by French theorist Jean Baudrillard's concept of the simulacrum. Additionally, the thesis addresses the treatment of Rosenquist's collages and paintings in publications and exhibitions since 1992 by suggesting how Baudrillard's ideas about the simulacrum clarify the museological narrativizing and consumption of the artist's work.

A systematic replication of the Family Connections parent-toddler training program. (open access)

A systematic replication of the Family Connections parent-toddler training program.

As more toddlers are being diagnosed with autism there is an increased need for very early intervention. Preliminary research on interventions suggests toddlers can make important developmental progress and that parents can be part of the intervention process. The purpose of this study was to systematically replicate a parent training program reported by Alai-Rosales et al. (2009). Specifically, the present study taught parents a set of teaching strategies that included arranging the environment, setting up learning opportunities, and using positive reinforcement. Baseline-intervention conditions were replicated across four parent-toddler dyads in order to assess the effects of training on parent and child behaviors. Results indicated increases in parent teaching behaviors, the child targeted behavior (facial orientation), as well as a non-targeted skill, joint attention. Findings are discussed in relation to the challenges of intervention and considerations for future research.

In good communication and in bad: A study of premarital counseling and communication skills in newlywed couples. (open access)

In good communication and in bad: A study of premarital counseling and communication skills in newlywed couples.

This study examined the effects of premarital counseling on newlywed communication. It was predicted that individuals who had participated in premarital counseling would have lower levels of demand/withdrawal communication and higher levels of spousal support. The effects of the format of the counseling were also examined. Individuals who had been married less than two years completed a survey measuring their marital satisfaction, levels of demand/withdraw, and perceived spousal support. Social learning theory was used as a theoretical lens. Results suggested that participating in premarital counseling has no affect on newlywed communication. Newlyweds who had been exposed to a group format during their counseling had higher marital satisfaction than those who had just participated in a one-on-one format with a counselor.

The Relationship Between TeacherInsight ™ Scores and Professional Development and Appraisal System Domain Scores (open access)

The Relationship Between TeacherInsight ™ Scores and Professional Development and Appraisal System Domain Scores

Many school districts and alternative certification programs use standardized interviews such as the TeacherInsight developed by the Gallup Organization. The TeacherInsight is a Web-based interview consisting of multiple choice and Likert-style items that produces a score between 0 and 100. The Gallup Organization claims that it helps hire the best teachers. The study analyzed the relationships between the TeacherInsight scores and the eight Professional Development Appraisal System (PDAS) domain scores for 527 teachers. The TeacherInsight scores produced a statistically significant correlation with only one of the eight PDAS domain scores. However, even that correlation (r = 0.14) was weak. All eight PDAS domain scores were only able to account for an additional 1.9% of the variance of TeacherInsight scores, above and beyond what was explained by the teachers' age, gender, years of experience, and highest degree earned. Another finding was that 47.4% of the teachers hired had TeacherInsight scores below the district recommended cutoff score of 67. The findings do not support the ability of the TeacherInsight to identify more effective teachers, based on Professional Development Appraisal System scores. The findings also cast doubt on the extent of consideration that principals in this district give the TeacherInsight scores during the …

Luminescence Resonance Energy Transfer-Based Modeling of Troponin in the Presence of Myosin and Troponin/Tropomyosin Defining Myosin Binding Target Zones in the Reconstituted Thin Filament (open access)

Luminescence Resonance Energy Transfer-Based Modeling of Troponin in the Presence of Myosin and Troponin/Tropomyosin Defining Myosin Binding Target Zones in the Reconstituted Thin Filament

Mechanistic details on the regulation of striated muscle contraction still need to be determined, particularly the specific structural locations of the elements comprising the thick and thin filaments. Of special interest is the location of the regulatory component, troponin, on the actin filament and how its presence influences the behavior of myosin binding to the thin filament. In the present study: (1) Luminescence resonance energy transfer was used to monitor potential conformational changes in the reconstituted thin filament between the C-terminal region of troponin T and myosin subfragment 1; (2) Location of troponin in previously derived atomic models of the acto-myosin complex was mapped to visualize specific contacts; and (3) Shortened tropomyosin was engineered and protein binding and ATPase assays were performed to study the effect of myosin binding close to the troponin complex. Analysis of the results suggest the following: (1) Irrespective of calcium levels, the C-terminal region of troponin T is located close to myosin loop 3 and a few actin helices that may perturb strong acto-myosin interactions responsible for force production. (2) Atomic models indicate myosin subfragment 1 cannot attain the post- powerstroke state due to the full motion of the lever arm being sterically hindered by …

Systematic Approaches to Predictive Computational Chemistry using the Correlation Consistent Basis Sets (open access)

Systematic Approaches to Predictive Computational Chemistry using the Correlation Consistent Basis Sets

The development of the correlation consistent basis sets, cc-pVnZ (where n = D, T, Q, etc.) have allowed for the systematic elucidation of the intrinsic accuracy of ab initio quantum chemical methods. In density functional theory (DFT), where the cc-pVnZ basis sets are not necessarily optimal in their current form, the elucidation of the intrinsic accuracy of DFT methods cannot always be accomplished. This dissertation outlines investigations into the basis set requirements for DFT and how the intrinsic accuracy of DFT methods may be determined with a prescription involving recontraction of the cc-pVnZ basis sets for specific density functionals. Next, the development and benchmarks of a set of cc-pVnZ basis sets designed for the s-block atoms lithium, beryllium, sodium, and magnesium are presented. Computed atomic and molecular properties agree well with reliable experimental data, demonstrating the accuracy of these new s-block basis sets. In addition to the development of cc-pVnZ basis sets, the development of a new, efficient formulism of the correlation consistent Composite Approach (ccCA) using the resolution of the identity (RI) approximation is employed. The new formulism, denoted 'RI-ccCA,' has marked efficiency in terms of computational time and storage, compared with the ccCA formulism, without the introduction of …
