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 …

Cindy McTee, Regents Professor of Composition in the College of Music at the University of North Texas, is one of America's leading composers. Her music is an eclectic blend of the "American" sound that is created by the use of a multiplicity of techniques. This document uses three of McTee's most recent (to date) works for wind band: Timepiece, Ballet for Band and Finish Line, to identify the primary stylistic characteristic's of the composer's music, which include: jazz influence; use of ostinati, pseudo-ostinati and machine-like rhythmic patterns and figures; creation of extended and angular melodic lines; progressive "walking" bass lines; and the use of octatonic and chromatic collections. Through the identification of stylistic characteristics, concise stylistic analysis of the works, interview transcript, list of composer's works to date, and selected discography, this document will add to the limited body of scholarly writing on the composer.

Given a real N by N matrix A, write p(A) for the maximum angle by which A rotates any unit vector. Suppose that A and B are positive definite symmetric (PDS) N by N matrices. Then their Jordan product {A, B} := AB + BA is also symmetric, but not necessarily positive definite. If p(A) + p(B) is obtuse, then there exists a special orthogonal matrix S such that {A, SBS^(-1)} is indefinite. Of course, if A and B commute, then {A, B} is positive definite. Our work grows from the following question: if A and B are commuting positive definite symmetric matrices such that p(A) + p(B) is obtuse, what is the minimal p(S) such that {A, SBS^(-1)} indefinite? In this dissertation we will describe the level curves of the angle function mapping a unit vector x to the angle between x and Ax for a 3 by 3 PDS matrix A, and discuss their interaction with those of a second such matrix.

This study modeled changes in pre-service teacher efficacy in mathematics and science over the course of the final year of teacher preparation using latent transition analysis (LTA), a longitudinal form of analysis that builds on two modeling traditions (latent class analysis (LCA) and auto-regressive modeling). Data were collected using the STEBI-B, MTEBI-r, and the ABNTMS instruments. The findings suggest that LTA is a viable technique for use in teacher efficacy research. Teacher efficacy is modeled as a construct with two dimensions: personal teaching efficacy (PTE) and outcome expectancy (OE). Findings suggest that the mathematics and science teaching efficacy (PTE) of pre-service teachers is a multi-class phenomena. The analyses revealed a four-class model of PTE at the beginning and end of the final year of teacher training. Results indicate that when pre-service teachers transition between classes, they tend to move from a lower efficacy class into a higher efficacy class. In addition, the findings suggest that time-varying variables (attitudes and beliefs) and time-invariant variables (previous coursework, previous experiences, and teacher perceptions) are statistically significant predictors of efficacy class membership. Further, analyses suggest that the measures used to assess outcome expectancy are not suitable for LCA and LTA procedures.

The issue of rising number of disasters, the overwhelming increase in number of older adults, and historically flawed evacuations presents real challenges. Disasters can strike anywhere, any time, and have devastating consequences. Since 1900, the number of Americans 65 and older has increased 12 times (from 3.1 million to 36.3 million). During the next two decades, the number of American baby boomers, now aged 45-64, who turn 65, will increase by 40%. As evidenced by recent disasters, the imperfections and vulnerabilities of flawed evacuations for older adults are still present. This study examined the level of willingness to evacuate among older adults in the event of a disaster. Despite the extensive literature on disasters and evacuation, some significant questions regarding evacuation and older adults have not been addressed. This study addressed the following concerns: (1) What is the willingness among older adults to evacuate when asked to do so by emergency management officials? (2) Does the call to evacuate being mandatory versus voluntary influence the willingness of seniors to evacuate? (3) Do preconditions (Gender, Marital Status, Age, Ethnic Origin, and Education Levels) influence the willingness to evacuate among older adults? The sample population consisted of 765 voluntary participants aged 60 …

The purpose of this study was to examine the relationship between resource allocation practices in specific categorical functions and student performance in reading and math. This study utilized quantitative research methods to study the effects of spending and performance over four years of analysis. Quantitative data was acquired utilizing information from the Texas Education Agency. The data was collected from 81 campuses and represented over 1,500 students. The study's outcomes reported that little or no correlation could be found between inputs (dollars spent in three categories) and outputs (student results in reading and math). However, subgroup analysis revealed that students from non- low socioeconomic (SES) households started out higher than their low SES counterparts, and low SES students performed worse over time in both reading and math. Math results decreased more dramatically than reading indicating a need for school-level training in data analysis to ensure that limited dollars are spent appropriately. The study recommends that principals and school administrators be especially knowledgeable in critical data analysis skills. The study further recommends that state policy-makers invest more heavily in early math instruction. In addition, the current study found that student achievement, in low-SES students, especially in mathematics is very alarming. Low …

With an increasingly technological and competitive world economy, more jobs require employees to have achieved the advanced skills and knowledge gained only through postsecondary education. The data regarding the supply and demand between the workforce and higher education present a challenge for community college technical programs. These are the programs charged training the new workforce. An effort to increase the persistence and three-year graduation rate for technical students is one of Tarrant County College District's initiatives to prepare students for the workforce. Therefore, the purpose of this study was to determine factors that contribute to the three-year graduation rates of students enrolled in technical programs at the Northwest Campus of the Tarrant County College District. A quantitative survey approach was selected for this study targeting 191 technical students. The results of this study showed that females, who had established a degree plan and declared a major during the first two semesters at the urban community college campus under study, graduated in three years. The graduation rates for males in this study were lower than for females. Also, technical students who were 18 to 35 years old were more likely to graduate. Students who did not complete a degree plan in …

The purpose of this study is to determine whether adult attachment style, psychological abuse in the marriage, conflict resolution strategies, and gender are associated with relational quality in childless couples in the early years of their marriage. Data were collected from 92 married couples who were recruited from university campuses, churches, and community organizations through e-mails, flyers, newspaper advertisements and mailings. Conceptualizing the interdependence of dyadic data from the actor-partner interdependence model (APIM), multilevel linear modeling (MLM) was used to analyze differences within and between couples. It was hypothesized that higher levels of attachment anxiety or avoidance, psychological abuse, and maladaptive conflict resolution strategies would be associated with lower relational quality. Results indicated that attachment avoidance had stronger associations with relational quality than did attachment anxiety, and that higher levels of attachment avoidance were associated with lower relational quality. Additionally, findings indicated a direct negative relationship between both actor and partner psychological abuse and the actor's relational quality. The discussion section addresses strengths and limitations of the present study as well as directions for future research.

This study examined the relationships between leadership practices of principals and strength of schools as sustainable professional learning communities. Strength of schools as professional learning communities was measured using the Professional Learning Communities Assessment; leadership practices were measured using the Leadership Practices Inventory both Self and Observer protocols. Findings indicated that neither principal's self-perceptions of their leadership practices nor teachers' assessments of their principals' leadership practices were related to strength of schools as professional learning communities. Findings did indicate ten specific leadership behaviors of principals that appear to be more highly related to strength of schools as learning communities. Further analysis which focused on the two strongest learning community schools and the two weakest learning community schools indicated that three specific leadership behaviors within Kouzes and Posner's practices of modeling the way and enabling others to act appear to be the most strongly related to reculturing schools as sustainable professional learning communities. Principals who set a personal example of what they expect of others are most likely to lead schools that function as strong learning communities. Additionally, principals who build consensus around a common set of values are also most likely to lead strong learning communities. Finally, principals who develop …

This study examines 797 Taiwanese pre-service early childhood teachers' diversity beliefs using the Personal and Professional Beliefs about Diversity Scales (PPBD). The purposes of this study are to: (a) validate the diversity belief's instrument, (b) investigate the relationship between diversity beliefs in both personal and professional contexts, (c) examine the group differences in diversity beliefs between pre-service teachers based on their demographic background, school characteristics, and cross-cultural experiences, (d) explore the influential determinants of diversity beliefs in the personal and professional contexts, and (f) identify the types of training early childhood pre-service teachers need regarding multicultural education in early childhood. The results indicate that (a) the professional context of PPBD is not robust to use in population outside the U.S. and needed to modify by adding more items based on current diversity literature and the cultural context in Taiwan, (b) school characteristics are the major contributors that foster pre-service teachers' diversity beliefs in both contexts, (c) school location is the most influential factor for the dependent variable of personal beliefs while experience of studying in another city and students' major become the salient factors for the professional beliefs about diversity, (d) the type of educational philosophy is contributing factor of …

During the 20th century, chamber works for harp expanded to include significantly different instrumentations, like flute, voice and harp. Indeed, a body of works for flute, voice, and harp began to develop mainly through the commissioning efforts of ensembles comprised of these instruments. This study of George Crumb's Federico's Little Songs for Children for flutes, soprano, and harp considers the unique advantages and challenges of this instrumentation and offers specific suggestions for performance. Attention to various compositional elements of Federico's Little Songs for Children, especially as they relate to the text, is also helpful in preparing to perform this work. The form, pitch material, and text-painting in the work allow for special opportunities to convey meaning to audiences in ways that do not rely on traditional tonal relationships. Accompanying the shift away from traditional tonal relationships, the development of the harp repertoire in chamber and solo settings during the 20th century also led to the development of many extended- techniques for this instrument. For the most part, these techniques have been described and given various notational symbols but not discussed in detail with regard to execution. Federico's Little Songs for Children itself requires several unique extended-techniques. Recommendations are given in …

This study examined the effectiveness of child centered play therapy (CCPT) with academically at-risk 1st graders. In this quasi-experimental design, twenty-one 1st grade students were assigned to the experimental group and 20 students were assigned to the no treatment control group. The children in the experimental group received two 30 minute play therapy sessions per week for the duration of eight weeks. Three hypotheses were analyzed. A two-factor repeated measures analysis of variances (SPANOVA) were performed on each dependent variable to determine if the experimental group performed differently from the control group across time according to the pretest and posttest results of the Young Child's Achievement Test (YCAT), the Pictorial Scale of Perceived Competence and Social Acceptance for Young Children (PSPCSAYC), and the Student-Teacher Relationship Scale (STRS). Additionally, partial η2 was calculated to determine practical significance. One hypothesis was retained at the .05 level of significance. Findings indicated that academically at-risk 1st graders who participated in CCPT scored statistically significant higher on academic achievement. Specifically, children assigned to the experimental group demonstrated a statistically significant increase in Early Achievement Composite (p = .03) when compared to children assigned to the no treatment control group. No statistical significant results were found …

This study explored the state of art education in Turkey as revealed by pre-service art education university instructors, and the potential of incorporating visual culture studies in pre-service art education in Turkey. The instructors' ideas about visual culture, and popular culture, the impact it might have, the content (objects), and the practices within the context of Turkey were examined. Visual culture was examined from an art education perspective that focuses on a pedagogical approach that emphasizes the perception and critique of popular culture and everyday cultural experiences, and the analysis of media including television programs, computer games, Internet sites, and advertisements. A phenomenological human science approach was employed in order to develop a description of the perception of visual culture in pre-service art education in Turkey as lived by the participants. In-person interviews were used to collect the data from a purposive sample of 8 faculty members who offered undergraduate and graduate art education pedagogy, art history, and studio courses within four-year public universities. This empirical approach sought to obtain comprehensive descriptions of an experience through semi-structural interviews. These interviews employed open-ended questions to gather information about the following: their educational and professional background; their definitions of art education and …

When Schenkerian theory began to influence scholarly circles in the United States, the primary - although not the only - work to which scholars had access was Schenker's last monograph, Der freie Satz. Reading textual passages and examining the many musical graphs in the companion volume of examples influenced their concept of the fundamental structure as Schenker understood it, as well as the relationship of the other levels (Schichten) to the larger structure. The problem is that most of the second generation of Schenkerian scholars were reading the 1956 second German edition, not the 1935 first German edition. The second edition had been altered for textual and musical content by Schenker's student, Oswald Jonas - so there is already a disconnect between the original version and the text scholars were reading at that time (the 1950s, 60s, and 70s). Furthermore, many younger North Americans were insufficiently fluent in German to be able to read the work in the original language. In order to make Schenker's treatise accessible to English-speaking scholars, Ernst Oster set about translating the work into English, a task completed in 1979 just after his death. The text was based on the second German edition (ed. Jonas, Vienna, …

New circuit design techniques that accommodate lower supply voltages necessary for portable systems need to be integrated into the semiconductor intellectual property (IP) core. Systems that once worked at 3.3 V or 2.5 V now need to work at 1.8 V or lower, without causing any performance degradation. Also, the fluctuation of device characteristics caused by process variation in nanometer technologies is seen as design yield loss. The numerous parasitic effects induced by layouts, especially for high-performance and high-speed circuits, pose a problem for IC design. Lack of exact layout information during circuit sizing leads to long design iterations involving time-consuming runs of complex tools. There is a strong need for low-power, high-performance, parasitic-aware and process-variation-tolerant circuit design. This dissertation proposes methodologies and techniques to achieve variability, power, performance, and parasitic-aware circuit designs. Three approaches are proposed: the single iteration automatic approach, the hybrid Monte Carlo and design of experiments (DOE) approach, and the corner-based approach. Widely used mixed-signal circuits such as analog-to-digital converter (ADC), voltage controlled oscillator (VCO), voltage level converter and active pixel sensor (APS) have been designed at nanoscale complementary metal oxide semiconductor (CMOS) and subjected to the proposed methodologies. The effectiveness of the proposed methodologies has …

Augeries is a multi-channel electro-acoustic composition for flute, clarinet, percussion, and tape. It is intended to be diffused through an 8-channnel playback system. Inspired by the first four lines of William Blake's Augeries of Innocence, Augeries captures the qualitative aspects of Blake's poetry by presenting the listener with an equally aperspectival aesthetic experience. The small-scale structure reflected on the large-scale form - the infusion of vastness and expansiveness into the fragile and minute. Augeries incorporates techniques of expansion and contraction, metonymic relationships, dilation and infolding of time, and structured improvisation to create an experience that is designed to explore the notion of musical time, and to bring to the listener the sense of time freedom. The critical analysis suggests that the increase in the notions of musical time, the aesthetics with which they conform, and the new time forms created, encapsulate communicative significance. This significance exists within a horizon of meaning. Semiotics illuminates an understanding of the structuring techniques used to render time as an area of artistic play. Understanding the aesthetics and mechanisms through which these techniques can be used constitutes a shared horizon of meaning. The concepts of cultural phenomenologist Jean Gebser, as explicated in The Ever-Present Origin, …

This study describes and implements a necessary preliminary strategic planning procedure, the Internal Environmental Scanning (IES), and discusses its relevance to strategic planning and university-sponsored lifelong learning program model selection. Employing a qualitative research methodology, a proposed lifelong learning-centric IES process based on Bryson's (2004) strategic planning model was tested at a large public university in the American Southwest with the intention of both refining the IES process for general use in the field as well as providing a set of useable reference documents for strategic planners at that university. The prototype lifelong learning IES process as tested proved to be highly effective in identifying and categorizing previously unrecognized lifelong learning programming and organizational structures and, was reasonably efficient in process execution. Lessons learned from the application of the prototype lifelong learning IES procedure led to the development of a revised scanning procedure. This revised procedure is considered more reliable and can be accomplished by a single investigator in as little as 35 production hours, providing a detailed snapshot of the total university lifelong learning system and a point of departure for the larger strategic planning effort.

The proposed study examined the relationship between parental anxiety, measured both subjectively (via self-report questionnaires) and objectively (via salivary cortisol) and the child's feeding progress. Children diagnosed with a feeding disorder were recruited with their parents at Our Children's House at Baylor (n=19; 11 females, 8 males). The patients and their parents were housed in the clinic for an eight-week intensive multidisciplinary pediatric feeding disorder treatment program. Calorie intake was recorded daily as outcome measures of treatment progression. Parental anxiety was measured by the Pediatric Inventory for Parents (PIP), state anxiety on the State Trait Anxiety Inventory (STAI), and by salivary cortisol at three different time points. The present study attempted to examine whether parental feeding (phase three of treatment program) would continue to cause a decrease in the child's caloric intake. In averaging ten meals prior to parental feeding in comparison to the average of ten meals following parental feeding, there was no significant difference as measured by a t-test. Paired t-tests examined parental anxiety from time one to time two and found that salivary cortisol increased significantly t(15) = -6.07, p = .000 from Time 1 (M = 2.30, SD = 1.64) to Time 2 (M = 5.24, …

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 …

Unlike other song composers of the 19th century, Pauline Viardot wrote in many languages and national styles. Her songs, "Haï Luli!," "In der Frühe," "Morirò," "La nuit monte/ Già la notte," "Canción de la Infanta," "Юноша и дьва," "Le Rêve de Jésus," are examples of Viardot's ability to compose in many languages and national styles.

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.

Despite the positive outcomes for inquiry-based science education and recommendations from national and state standards, many teachers continue to rely upon more traditional methods of instruction This causal-comparative study was designed to determine the effects of the Inquiry Institute, a professional development program that is intended to strengthen science teachers' pedagogical knowledge and provide practice with inquiry methods based from a constructivist approach. This study will provide a understanding of a cause and effect relationship within three levels of the independent variable-length of participation in the Inquiry Institute (zero, three, or six days)-to determine whether or not the three groups differ on the dependent variables-beliefs, implementation, and barriers. Quantitative data were collected with the Science Inquiry Survey, a researcher-developed instrument designed to also ascertain qualitative information with the use of open-ended survey items. One-way ANOVAs were applied to the data to test for a significant difference in the means of the three groups. The findings of this study indicate that lengthier professional development in the Inquiry Institute holds the most benefits for the participants.

Arnold Schoenberg's teaching career spanned over fifty years and included experiences in Austria, Germany, and the United States. Schoenberg's teaching assistant, Leonard Stein, transcribed Schoenberg's class lectures at UCLA from 1936 to 1944. Most of these notes resulted in publications that provide pedagogical examples of combined elements from Schoenberg's European years of teaching with his years of teaching in America. There are also class notes from Schoenberg's later lectures that have gone unexamined. These notes contain substantial examples of Schoenberg's later theories with analyses of masterworks that have never been published. Both the class notes and the subsequent publications reveal Schoenberg's comprehensive approach to understanding the presentation of the Gedanke or musical idea. In his later classes especially, Schoenberg demonstrated a method of analyzing musical compositions using illustrations of elements of the Grundgestalt or "basic shape," which contains the technical aspects of the musical parts. Through an examination of his published and unpublished manuscripts, this study will demonstrate Schoenberg's commitment to a comprehensive approach to teaching. Schoenberg's heritage of eighteenth- and nineteenth-century music theory is evident in his Harmonielehre and in his other European writings. The latter include Zusammenhang, Kontrapunkt, Instrumentation, Formenlehre (ZKIF), and Der musikalische Gedanke und die Logik, …

Nine universities in the United States with the greatest number of international students and having an accredited music program through the National Association of Schools of Music (NASM) were selected. Survey research methodologies were used to identify the status of the international music students from East Asia in U.S. higher education institutions and to determine their attitudes toward their schools. Among East Asian international music students at US higher education institutions, the results indicated that the professor's reputation, scholarships, and the program's reputation were perceived as the most influential factors impacting the program choice; a good relationship with professors, good feedback from professors, and emotional stability were perceived as the most influential factors impacting academic success; and the professor's teaching, the professor's expertise, and the improvement of musical skills were perceived as the most influential factors impacting students' satisfaction level. The most problematic issues reported were the language barrier and the cultural differences between their host and own countries. In addition, many of the East international music students in this study noted financial difficulties.
