Park "Pepper" Adams, III (1930-1986) is one of the most influential baritone saxophonists in the history of modern jazz. In addition to his time feel, his timbre, and other conceptual techniques, a great deal of Adams's improvisational style and vocabulary can be illustrated by his use of three motivic devices. These three motivic devices are: (1) his utilization of the sixth degree of the major scale as an important melodic pitch; (2) his use of a paraphrased portion of the melody of the popular song "Cry Me a River;" and (3) his use of the half-whole octatonic scale when the rhythm section sounds a dominant chord. This dissertation traces the way in which Adams applies these three motivic devices through four of his original compositions, "Enchilada Baby," "Bossallegro," "Lovers of Their Time," and "Rue Serpente." All four of these compositions were recorded by Adams on his 1980 album, The Master. In addition to the motivic analysis, a biography of Adams is included. Complete transcriptions by the author of Adams's improvised solos on the four compositions are included in the appendices.

This study sought to determine if the dominant learning styles of high school teachers is related to the amount of time computers are used in the classroom by students. It also examined the types of software used by those teachers, and their levels of technology adoption. Subjects (N=177) were from high schools in a large urban school district. Instrumentation included the Gregorc Style Delineator, a modified version of the Snapshot Survey and the Stages of Adoption of Technology. An ANOVA showed no statistical significance between teachers with different dominant learning styles in the numbers of minutes per week that computers were utilized in their classrooms with students. A chi square test showed no statistical significance in the types of software used in the classrooms of teachers with different dominant learning styles. A chi square test showed no statistical significance in the Stages of Technology Adoption of teachers with different dominant learning styles.

This dissertation introduces a Korean composer, Isang Yun (1917-1995), who embraced European traditions but retained Asian characteristics in his compositions. Attending the 1958 summer course in Darmstadt in Germany, Yun was strongly influenced by the avant-garde style of Boulez, Stockhausen, Nono, and Cage. In addition to his work as a composer, Yun distinguished himself, as one of the most important Asian composers to blend Eastern and Western music; and although his musical training focused on Western music, he continued the pursuit of Eastern sounds and philosophies throughout his musical life. Imprisoned in 1967 by the South Korean government, Isang Yun's music, particularly in later life, incorporates his beliefs on social and political issues together with musical ideas. Although his love of country was deep, Isang Yun was not allowed to return to South Korea, and he lived in Germany for the remainder of his professional life. In this study, my purpose is to investigate the development of Yun's musical ideas from his acceptance of Taoism four structures in the world: the Tao, heaven, earth, and man. The presence of both Western and Eastern influences in Yun's music provides the basic of his musical style, and analysis of Salomo für Altoflöte …

Wildland fires in the United States are not always confined to wilderness areas. The growth of population centers and housing developments in wilderness areas has blurred the boundaries between rural and urban. This merger of human development and natural landscape is known in the wildland fire community as the wildland urban interface or WUI, and it is within this interface that many wildland fires increasingly occur. As wildland fire intrusions in the WUI increase so too does the need for tools to assess potential impact to valuable assets contained within the interface. This study presents a methodology that combines real-time weather data, a wildland fire behavior model, satellite remote sensing and geospatial data in a geographic information system to assess potential risk to human developments and natural resources within the Austin metropolitan area and surrounding ten counties of central, Texas. The methodology uses readily available digital databases and satellite images within Texas, in combination with an industry standard fire behavior model to assist emergency and natural resource managers assess potential impacts from wildland fire. Results of the study will promote prevention of WUI fire disasters, facilitate watershed and habitat protection, and help direct efforts in post wildland fire mitigation and …

The integration of copper (Cu) and dielectric materials has been outlined in the International Technology Roadmap for Semiconductors (ITRS) as a critical goal for future microelectronic devices. A necessity toward achieving this goal is the development of diffusion barriers that resolve the Cu and dielectric incompatibility. The focus of this research examines the potential use of tungsten nitride as a diffusion barrier by characterizing the interfacial properties with Cu and evaluating its process capability for industrial use. Tungsten nitride (β-W2N) development has been carried out using a plasma enhanced chemical vapor deposition (PECVD) technique that utilizes tungsten hexafluoride (WF6), nitrogen (N2), hydrogen (H2), and argon (Ar). Two design of experiments (DOE) were performed to optimize the process with respect to film stoichiometry, resistivity and uniformity across a 200 mm diameter Si wafer. Auger depth profiling showed a 2:1 W:N ratio. X-ray diffraction (XRD) showed a broad peak centered on the β-W2N phase. Film resistivity was 270 mohm-cm and film uniformity < 3 %. The step coverage (film thickness variance) across a structured etched dielectric (SiO2, 0.35 mm, 3:1 aspect ratio) was > 44 %. Secondary ion mass spectroscopy (SIMS) measurements showed good barrier performance for W2N between Cu and SiO2 …

Density functional theory has been used in combination with the correlation consistent and polarization consistent basis sets to investigate the structures and energetics for a series of first-row closed shell and several second-row molecules of potential importance in atmospheric chemistry. The impact of basis set choice upon molecular description has been examined, and irregular convergence of molecular properties with respect to increasing basis set size for several functionals and molecules has been observed. The possible reasons and solutions for this unexpected behavior including the effect of contraction and uncontraction, of the basis set diffuse sp basis functions, basis set superposition error (BSSE) and core-valence sets also have been examined.

Effects of episodic exposures have gained attention as the regulatory focus of the Clean Water Act has shifted away from continuous-flow effluents. Standardized laboratory toxicity tests require that exposure be held constant. However, this approach may not accurately predict organism responses in the field following episodic exposures such as those associated with rain-driven runoff events or accidental pollutant discharge. Using a modified version of the 7-day short-term chronic test recommended by the US Environmental Protection Agency, Ceriodaphnia dubia were exposed to copper or cadmium for durations ranging from 1 minute to 24 hours. In addition, adult reproductive recovery and effects on second generation individuals was assessed following select copper exposures. Finally, cadmium exposures were compared in reconstituted hard water (RHW) and municipal treated wastewater effluent (TWE). Following exposure, organisms were transferred to clean RHW or TWE and maintained for the remainder of the test. No- and lowest observed effect concentrations (NO- and LOECs) increased logarithmically with respect to logarithmic decreases in duration regardless of metal, endpoint or water type. Effective concentrations of cadmium however, were usually higher than those of copper, especially in TWE. LOECs for C. dubia survival following 24-hour and 5-minute exposures to copper were 116 and 417 …

The purpose of this dissertation is to provide an introduction to the composer, Lawrence Weiner, and to his Concerto for Guitar and Orchestra, one of the many neglected guitar concerti that merits closer study and more frequent performances. Weiner, a prolific and prominent composer in the South Texas region, composed the concerto in 1986. The concerto was never published. This dissertation is the first attempt to study Weiner's Concerto for Guitar and Orchestra to date. This study provides insight into the compositional style of Weiner, and the understanding and performing of this work. The compositional language of this concerto is examined through an analysis of the aspects of form, harmonic/tonal scheme and thematic development. A performance edition and suggestions that are approved by the composer are also presented.

The older adult population in the United States is rapidly expanding both because of longer life expectancies as well as the aging of the baby boomers. While vision impairment is a growing concern among older adults, there have been few, mostly small studies, of the impact of vision impairment on this population. The present study uses a national data set, the Second Supplement on Aging (1994 -1996) from the National Health Interview Survey, in a cross-sectional study of 9,447 civilian non-institutionalized persons, aged 70 years and over at the time of their interview. The SOA II has been studied in the context of a social theory of aging that emphasizes interdependence through the life course using a stress process model that has been refined into a disability model. Disability is understood as a social construction outcome rather than as a medical outcome. Vision impairment is the stressor which is mediated by health (falls, functioning and self-health report), financial resources (education, income and having only public health insurance) and social support (marital, living along, having no living children, social activities in number and intensity). Depression is a possible, but not a necessary result of vision impairment. Disability may result when a …

The No Child Left Behind Act and National Council of Teachers of Mathematics' Principles and Standards both had a significant impact on the format and content of the Texas Assessment of Knowledge and Skills (TAKS) math test. Content analysis of the 2004 TAKS eighth grade math test identified the prevalence of linguistic complexity, mathematical rigor, and visual presentation factors and explored their relationship to student success on individual test items. Variables to be studied were identified through a review of literature in the area of reading comprehension of math word problems. Sixteen variables of linguistic complexity that have been significantly correlated with student math test performance were selected. Four variables of visual presentation were identified and ten variables of mathematical rigor. An additional five variables of mathematical rigor emerged from preliminary study of the 2003 TAKS math test. Of the 35 individual variables, only four reached a significant level of correlation with the percent of students correctly answering a given test item. The number of digits presented in the problem statement and number of known quantities both exhibited a significant positive correlation with the dependent variable. The number of times a student had to perform a multiplication operation had a …

During the years of the Holocaust, song literature was needed to fulfill the unique needs of people caught in an unimaginable nightmare. The twelve years between 1933 and 1945 were filled with a brutal display of man's inhumanity to man. Despite the horrific conditions or perhaps because of them, the Jewish people made music, and in particular, they sang. Whether built on a new or an old melody, the Holocaust song literature continues to speak to those of us who are willing to listen. This body of work tells the world that these people lived, suffered, longed for vengeance, loved, dreamed, prayed, and tragically, died. This repertoire of songs is part of the legacy, the very soul of the Jewish people. This study contains a brief look at the historical circumstances, and through the song literature of Hirsh Glick, Mordechai Gebirtig and Simon Sargon, life within the ghetto, the concentration camp, the decisions families had to make, the choices to fight back against incredible odds, the place of faith within this nightmare, and a look at the lives and works of the composers themselves.

Sandtray therapy, a modality of play therapy, has been used in a variety of ways as the treatment intervention with different theoretical approaches; however, there is a very limited amount of empirical research. The purpose of this research is to examine the effectiveness of group sandtray therapy at school with preadolescents identified with behavioral difficulties. This is a pretest-posttest control group design. Participants in the experimental group received sandtray therapy in group for ten weeks, and participants in the wait-list control group received no treatment intervention. The researcher compared two groups to examine the overall effectiveness of sandtray therapy as determined by the scores of the Child Behavior Checklist-Teacher Report Form (CBC-TRF), Parent Report Form (BASC-PRF), and Self Report of Personality (BASC-SRP). Based on teachers' reports, statistically significant difference existed between the two groups in terms of preadolescents' overall behaviors, externalizing behavior problems, and internalizing behavior problems after the ten week treatment intervention. The effect sizes were medium (d= .52-.59). According to parents' reports, a statistically significant difference was found regarding preadolescents' externalizing behavior problems, and the effect size was medium (d=.63). No statistically significant differences were found regarding preadolescents' total behaviors and internalizing behavior problems based on BASC-PRF. The …

The marimba is rapidly achieving greater importance as a solo percussion instrument. Solo compositions for the marimba have been commissioned and performed only in the last sixty years. The 1986 National Endowment for the Arts Solo Marimba Commission is considered one of the most important commissioning projects in the history of marimba literature. Two compositions created through this project, Velocities by Joseph Schwantner and Reflections on the Nature of Water by Jacob Druckman have become two of the most influential works in contemporary marimba music. This thesis will focus on a historical perspective of the project, as well as theoretical aspects and performance issues related to these two compositions. The National Endowment for the Arts (NEA) issued a consortium commissioning grant through the Percussive Arts Society (PAS) in 1986 to three internationally renowned marimbists, William Moersch, Leigh Howard Stevens and Gordon Stout. Three Pulitzer Prize winners were brought together to compose three new works for the marimba. The resulting pieces were: Reflections on the Nature of Water by Jacob Druckman, Velocities by Joseph Schwantner, and Islands from Archipelago: Autumn Island by Roger Reynolds. A brief history of the classical concert marimba and the development of solo marimba literature is provided …

Organizational innovation has been of central interest in recent years because of its importance for organizational survival and competitive advantage. Researchers in the field have divided the innovation process into stages in an attempt to understand the innovation process and the factors that affect it. However, empirical studies that examine the relationship between the stages are scarce. In addition, although business strategy is emphasized as an important factor in the innovation process, little is known about its role in the innovation process and its effect on the stages. This research provides empirical support for the relationship between the stages of the innovation process and the moderating effect of organizational strategy on the relationship between the stages within the two stage model of innovation. In this study, a direct, positive relationship is proposed between the innovation generation (first stage) and innovation outcome (second stage) stages of the innovation process. Dimensions of innovation outcome that are examined include innovation type (product innovation and process innovation), innovation radicalness and innovation frequency. Low cost, differentiation and market orientation strategies are proposed to be moderators on the relationship between the stages. To test the proposed relationships, a survey was mailed to executives who are involved …

Emotional Intelligence (EI) has been relatively unstudied after young adulthood. Yet there are a variety of reasons to expect that EI may be different at mid life than in young adulthood. Normative life experiences may lead to increases in EI, and as the array of different environments and experiences increases with age, one might expect greater individual differences in EI. Similarly, if EI is located somewhere at the intersection of personality and intelligence, as some have speculated, it may follow a course of structural differentiation similar to cognitive abilities. EI may be more closely linked to social variables such as loneliness and friendships at mid life, and its relation to established personality and ability factors such as the Big Five (Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness) and fluid and crystallized abilities may also vary with age. These hypotheses were investigated in samples of 292 young adults and 246 mid life adults, using the Schutte Self Report Emotional Intelligence Inventory, the NEO-Five Factor Personality Inventory, markers of crystallized and fluid ability from Horn's Crystallized/Fluid Sampler, and a variety of other measures. Mid life adults scored higher on overall EI scores, but evidenced no greater range of individual differences than did young …

Using factors of low income, parents' levels of education, and family composition as determinants of educationally at-risk status, study investigated differences between first generation, undergraduate college students from families in lowest quintile of income in the U.S, One group consisted of students from single-parent households and the other of students from two-parent households. Data were from CIRP 2003 College Student Survey (CSS) and its matched data from the Freshman Survey (Student Information Form - SIF). Differences examined included student inputs, involvements, outcomes, and collegiate environments. Included is portrait of low income, first generation college students who successfully navigated U.S. higher education. The number of cases dropped from 15,601 matched SIF/CSS cases to 308 cases of low income, first generation college students (175 from single-parent households and 133 from two-parent households). Most of the 308 attended private, 4-year colleges. Data yielded more similarities than differences between groups. Statistically significant differences (p < .05) existed in 9 of 100 variables including race/ ethnicity, whether or not English was first language, and concern for ability to finance education as freshman. Data were not generalizable to all low income, first generation college students because of lack of public, 4-year and 2-year colleges and universities …

Childhood sexual abuse (CSA) has been the subject of much recent controversy as a result of Rind, Tromovitch and Bauserman's (1998) meta-analytic examination of CSA, which found a weak relationship between CSA and self-reported psychopathology in college samples. There have been few studies of CSA which look beyond self-report. The present study is an exploration of the relationships between CSA, quantitative electroencephalographic (QEEG), neuropsychological, and psychological measurements in 24 high-functioning, unmedicated CSA adults who were matched for age, gender, and handedness with a group of adults without CSA (NCSA). The objectives of this study were to: 1) examine EEG abnormalities associated with CSA, 2) investigate QEEG cortical coherence in the groups using neuroelectric Eigen image (NEI) connectivity indices (Hudspeth, 1999), 3) integrate personality differences associated with CSA with EEG differences, and 4) better understand left versus right hemisphere functioning in CSA using intelligence testing. An examination of QEEG cortical coherence revealed moderate to large effect sizes indicating patterns of decreased connectivity between brain regions on the right frontally in the delta band, and frontally and centro-temporally on the right in the alpha band, and posteriorly in the alpha and beta bands, as well as in the cross-correlation; increased connectivity between …

Using data from a national survey, this study examines income and other key variables (division of labor and work-family conflict) and their relationship to marital satisfaction. This study builds upon the body of research regarding working couples and women's increased participation in the paid labor force as well as evaluates the findings in the context of data gathered from the recent United States census. Results from this study also are compared to the findings of other key studies. Emergent data may be used to prepare counselors to work more effectively with couple clients and to assist employers in the development of work life policies for dual career and dual earner employees. Results from the multiple regression revealed no direct effects of income on marital satisfaction. For this sample, increases in work family conflict contributed to less marital satisfaction as did the presence of children. Increased participation in household chores by respondents' partners contributed to increased marital satisfaction. No differences were observed by gender. Limitations of the study, recommendations for further research, and implications for practitioners also are addressed.

This dissertation is a study of the effect of Texas's charter high schools on diploma graduation and General Educational Development (GED) attainment. Utilizing data from the Texas Schools Project at the University of Texas at Dallas, the study follows a cohort of Texas students enrolled as 10th graders in the fall of 1999 and tracks their graduation outcomes through the summer of 2002 when they were expected to have completed high school. The analysis uses case study research and probit regression techniques to estimate the effect of charter school attendance on graduation and GED outcomes as well as the effect of individual charter school characteristics on charter students' graduation outcomes. The study's results indicate that charter school attendance has a strong negative effect on diploma graduation and a strong positive effect on GED attainment. In addition, the study finds that charter schools that offer vocational training, open entry/exit enrollment options, and charters that are operated in multiple sites or "chain" charters have positive effects on charter students' diploma graduation outcomes. Charters that offer accelerated instruction demonstrate a negative effect on diploma graduation. The study finds that charter school graduation outcomes improve as charters gain experience and that racially isolated minority …

In an extension of Louden's work, this study investigated identity development across the lifespan by applying Erickson's and Marcia's identity constructs to two developmental models, the selective optimization and compensation model and a holistic wellness model. Data was gathered from traditionally aged college freshmen and adults older than 60 years of age. Uncommitted identity statuses and work and leisure wellness domains were endorsed across both groups, suggesting that identity for these groups is in a state of fluctuation yet entailing participation as a productive member of society. Emerging adult findings imply that identity diffused and moratorium identity styles are more similar in terms of cognitive, behavioral, and emotional functioning than past literature suggests for this age group. Findings also indicate that identity development is not a process completed by older adulthood, but is an ongoing, lifelong process perhaps driven by contextual factors such as health changes, unpredictable life events, social support group changes, and others. Coping method utilization and overall wellness varied between the two age groups. Conceptually, the SOC model can be viewed as embedded within each of the wellness domains such that selection, optimization, and compensation activities may be carried out within each of the various domains and …

This study develops a model of collaboration choice among city governments. The theoretical model suggests that collaboration is a function of transaction costs that vary with different institutional arrangements utilized in cities, as well as the degree of competition between cities. This study argues that cities facing high transaction costs and high competition are less likely to participate in collaboration and to participate less deeply. Underlying these environmental factors are resource factors that create incentives for cities to collaborate for efficiency gains, which affect both the decision to collaboration and the depth of collaboration. Eleven hypotheses are presented to explain why cities choose to participate in collaboration in the first stage of the analysis and how deeply they collaborate in the second stage. Utilizing a Heckman model of this two-stage process, I find broad support for a number of variables that measure each of these theoretical constructs.

This study examined the degree to which University of North Texas (UNT) instructors involved in Web-based instruction are implementing teaching strategies as identified in Chickering and Gamson's (1987) model, seven principles for good practice in undergraduate education. In addition, the study examined training received by instructors in developing and delivering a Web-based course and the relationships between their training and reported use of the teaching strategies in the seven principles. The study also examined the relationship between the number of Web-based courses taught and the use of the teaching strategies. Seventy-two surveys were distributed, with a return rate of 90.3%. Results of the first three research questions were as follows: (a) Self-taught (49%) and UNT Center for Distributed Learning (CDL) (31%) were the most frequently used types of training in preparation for teaching a Web-based course, whereas peer taught (17%) and conferences/workshops (3%) were the least used; (b) the average number of Web-based courses taught by the instructors was M = 8.26; and (c) the most frequently used principles were "Gives prompt feedback" and "Communicates high expectations." UNT CDL assists faculty with the development and delivery of online courses, offering a series of training courses to better prepare faculty to …

Cyberterrorism and cybercrime present new challenges for law enforcement and policy makers. Due to its transnational nature, a real and sound response to such a threat requires international cooperation involving participation of all concerned parties in the international community. However, vulnerability emerges from increased reliance on technology, lack of legal measures, and lack of cooperation at the national and international level represents real obstacle toward effective response to these threats. In sum, lack of global consensus in terms of responding to cyberterrorism and cybercrime is the general problem. Terrorists and cyber criminals will exploit vulnerabilities, including technical, legal, political, and cultural. Such a broad range of vulnerabilities can be dealt with by comprehensive cooperation which requires efforts both at the national and international level. "Vulnerability-Comprehensive Cooperation-Freedom Scale" or "Ozeren Scale" identified variables that constructed the scale based on the expert opinions. Also, the study presented typology of cyberterrorism, which involves three general classifications of cyberterrorism; Disruptive and destructive information attacks, Facilitation of technology to support the ideology, and Communication, Fund raising, Recruitment, Propaganda (C-F-R-P). Such a typology is expected to help those who are in a position of decision-making and investigating activities as well as academicians in the area of …

Metal oxide reactions at metal oxide surfaces or at metal-metal oxide interfaces are of exceptional significance in areas such as catalysis, micro- and nanoelectronics, chemical sensors, and catalysis. Such reactions are frequently complicated by the presence of high electric fields and/or H2O-containing environments. The focus of this research was to understand (1) the iron oxide growth mechanism on Fe(111) at 300 K and 500 K together with the effect of high electric fields on these iron oxide films, and (2) the growth of alumina films on two faces of Ni3Al single crystal and the interaction of the resulting films with water vapor under non-UHV conditions. These studies were conducted with AES, LEED, and STM. XPS was also employed in the second study. Oxidation of Fe(111) at 300 K resulted in the formation of Fe2O3 and Fe3O4. The substrate is uniformly covered with an oxide film with relatively small oxide islands, i.e. 5-15 nm in width. At 500 K, Fe3O4 is the predominant oxide phase formed, and the growth of oxide is not uniform, but occurs as large islands (100 - 300 nm in width) interspersed with patches of uncovered substrate. Under the stress of STM induced high electric fields, dielectric …
