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.

This dissertation presents the social virtual interface (SVI) model, which was born out of a need to develop a viable model of the complex interactions, information flow and information seeking behaviors among undercover officers. The SVI model was created from a combination of various philosophies and models in the literature of information seeking, communication and philosophy. The questions this research paper answers are as follows: 1. Can we make use of models and concepts familiar to or drawn from Information Science to construct a model of undercover police work that effectively represents the large number of entities and relationships? and 2. Will undercover police officers recognize this model as realistic? This study used a descriptive qualitative research method to examine the research questions. An online survey and hard copy survey were distributed to police officers who had worked in an undercover capacity. In addition groups of officers were interviewed about their opinion of the SVI model. The data gathered was analyzed and the model was validated by the results of the survey and interviews.

The purpose of this quantitative and qualitative study was to determine retrospectively marital satisfaction and stability following the near-death experience (NDE) of one of the marital partners, focusing on the role of Gottman's Sound Marital House (1999) in the couple's relationship before and after the NDE. The researcher used the Locke-Wallace Marital Adjustment Test (1959), the Weiss-Ceretto Marital Status Inventory (1980), and a modification of Gottman's Shared Meanings Questionnaire (1999). The first group of participants included 26 NDErs. To create as comparable a group as possible, the researcher designed a life-changing event (LCE) group of 26 people who used as their referent the non-NDE-related experience they considered their most life-changing one during their marriage. Sixty-five percent of the marriages in which the NDErs were involved at the time of their NDEs ended in divorce. This number is in contrast to the 19 percent of LCE participants whose marriages ended in divorce. Marital adjustment, marital stability, and meanings in marriage between retrospectively based pre-event and post-event composite scores were statistically significantly different between the NDErs and LCErs. Low effect sizes were identified for each of the instruments except the Weiss-Ceretto Marital Status Inventory, which had a moderate effect size. Strong correlations …

Developing effective literacy skill has become an increasingly critical skill in today's information age. Students with emotional/behavioral disorders (E/BD) routinely lack these skills and are not being taught how to read effectively. The field of special education needs more comprehensive and specific information about how to most effectively teach reading skills to students with E/BD. When reading interventions are conducted using student with E/BD, the interventions are generally drawn from the LD field. The assumption is that the reading interventions that have worked with students with LD will work equally well with the E/BD population. This study performed a meta-analysis to examine whether reading interventions are equally effective on the E/BD and LD populations. In addition, it will examine whether the instruction mode (e. g., peer, self, or teacher directed), gender, or grade group affects the success of the intervention. The meta-analysis found that the reading interventions for both disability groups had high effect sizes. In addition, neither disability group, teaching method, gender, nor grades were predictive of the variance in the effect size. These results indicate that reading programs that have been designed for students with LD are also effective for students with E/BD and furthermore, reading programs can …

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 …

The development of cholinergic neurons in mouse frontal cortex was studied both in vivo and in vitro by immunocytochemistry with an antibody to choline acetyltransferase (ChAT), the enzyme responsible for acetylcholine synthesis. While cortical cholinergic neurons have previously been characterized in rat cortex, up until very recently, intrinsic cortical cholinergic neurons were considered to be absent in mouse, and little is known about their development or phenotypic characteristics. The present study found no ChAT-positive neurons in mouse frontal cortex on postnatal day 0 (P0, the day of birth). On P7 there were few, faintly stained, ChAT-positive neurons. The numerical density of ChAT-positive neurons increased substantially with age, from none on P0, to 9.2 + 1.4 on P7, to 14.8 + 0.9 on P16, and 41.6 + 3.9 in adulthood. Considering that the numerical density of total neurons decreases during this postnatal period, the data represent a marked developmental increase in the percentage of cholinergic neurons. The development of cholinergic neurons showed very similar timelines in rat and mouse frontal cortex. Cultures prepared from mouse frontal cortex on embryonic day 16 were maintained for 25, 76, or 100 days in vitro (div). The percentage of ChAT-positive neurons was considerably higher than …

Although the most well-known collaborations of William Plomer and Benjamin Britten are the three church parables (or church operas) - Curlew River, The Burning Fiery Furnace, and The Prodigal Son - by the time of the completion of Curlew River in 1964, the librettist and composer had been working together for well over a decade. During that time, they had completed the opera Gloriana and had considered collaborating on three other projects: one a children's opera on Beatrix Potter's The Tale of Mr. Tod, one on an original story of Plomer's called "Tyco the Vegan," and one on a Greek myth (possibly Arion, Daedalus and Icarus, or Phaëthon). Far from being footnotes to the parables, these early collaborations established Plomer and Britten's working relationship and brought to light their common interests as well as their independent ones. Their successive early collaborations, therefore, can be thought of as a conversation through creative expression. This metaphor of conversation can be applied both to successive collaborations and to the completed Gloriana, in that the libretto and the music can be seen as representing different interpretations of both major and minor characters in the opera, including Elizabeth I and Robert Devereux, Earl of Essex. …

The portrayals of mothers and fathers in children's literature as companions, disciplinarians, caregivers, nurturers, and providers were documented in this research. The impact of time of publication, sex of author, award-winning status of book, best-selling status of book, race of characters, and sex of characters upon each of the five parental roles was assessed using descriptive statistics, cross-tabulation, and multinomial logistic regression techniques. A survey instrument developed for this study was completed for each of the 300 books randomly selected from the list of easy/picture books in the Children's Catalog (H.W. Wilson Company, 2001). To ensure all time periods were represented, the list was stratified by decades before sampling. It was expected that parental role portrayals would become more egalitarian and less traditional in each successive time period of publication. Male authors were expected to portray more egalitarian parental roles, and the race and sex of the young characters were not expected to influence parental portrayals. Award-winning books were expected to represent more egalitarian parental roles. Books that achieved the Publisher's Weekly all-time best-selling status were expected to portray parents in less egalitarian roles. Secondary analyses explored the prevalence of mothers' occupations, parental incompetence, and dangerous, solo child adventures. While …

The Individuals with Disabilities Education Act (IDEA) mandated that each child who qualifies for special education must have an individualized education program (IEP). Disciplinary issues and procedures under IDEA have been a source of concern among parents, schools, and advocates from disability groups. At issue are fundamental concerns about the protection of rights for students with disabilities, which must be balanced with the ability of school personnel to maintain safe school environments that benefits all students. This research examined the four survey questions related to discipline from a state-wide survey conducted by Education Service Center (ESC) Region 9 through a comparison of selected disability categories as they compare to the responses received from parents of students with the disability category of emotional/behavioral disorders (E/BD). In addition, the research examined the open-ended questions from surveys to determine the types of concerns reported by parents. Data accrued from a focus group of parents receiving special education services are also reported. Parents of students identified as having an E/BD rated their understanding of the school's discipline policy lower than parents of students from other eligibility categories. Almost 67% of parents of students identified as having E/BD stated that they knew that their child …

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.

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 …

This study explored public safety programs in publicly controlled American community colleges. The need for accurate and complete information in an era of homeland security and defense is paramount as government, education, the private sector, and the citizenry interact to ensure a safer nation. The general purposes of this study were to compile current descriptive information on public safety programs and curricula in America's publicly controlled community colleges, and to identify problems and prospects inherent in the administration of these programs. Information is critical as community colleges continue to struggle with decreased funding and seek alternative sources of revenue. Community colleges represent a tremendous network for course delivery, such as homeland security training, but struggle to obtain the attention or the funding from the federal government. A review of pertinent literature provided the foundation of a 100-item survey questionnaire that was mailed to a random sample of 200 public safety administrators at American community colleges. The study also included a review of archival data to further describe the programs. Of the 200 instruments sent, 97 (48.5%) were completed, returned, and useable. From the literature, the survey results, and the archival data, a comprehensive list of community colleges with public safety …

The purpose of this dissertation is two-fold: one is to analyze the narratives of Acis and Galatea written by Ovid, and the two libretti by Handel's librettists including Nicola Giuvo (1708) and John Gay (1718) with John Hughes and Alexander Pope; the other is to correlate this textual analysis within the musical languages. A 1732 pastiche version is excluded because its bilingual texts are not suitable for the study of relationships between meaning and words. For this purpose, the study uses the structural theory- -mainly that of Gérard Genette--as a theoretical framework for the analysis of the texts. Narrative analysis of Acis and Galatea proves that the creative process of writing the libretto is a product of a conscious acknowledgement of its structure by composer and librettists. They put the major events of the story into recitative and ensemble. By examining the texts of both Handel's work, I explore several structural layers from the libretti: the change of the characterization to accommodate a specific occasion and the composer's response to contemporary English demand for pastoral drama with parodistic elements, alluding to the low and high class of society. Further, Polyphemus is examined in terms of relationships with culture corresponding to …

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.

The present study examined the use of MacDonald's Expressions of Spirituality instrument with a younger and older adult sample. Specifically, MacDonald's proposed five factor model was assessed for fit with a sample of college age participants as well as a sample of adults over the age of 65. A confirmatory factor analysis was conducted to assess the fit of this model with samples, and this was followed by an exploratory factor analysis, and the results were considered in light of measurement equivalence and the definitions of the constructs of religiosity and spirituality. Further analyses examined levels of religiousness as well as relationships between religiousness/spirituality and potential correlates, such as postformal thinking, life events including changes and losses, emotional and physical well-being, and family upbringing, comparing young and older adult samples. Results of the confirmatory factor analysis revealed a solution with a better fit than MacDonald's model for both younger and older adults. While the number of factors were the same for both samples, item loadings and cross-loadings differed between the younger and older adult samples. Exploratory factor analysis yielded a four factor solution, with religiousness and spirituality items loading onto one factor. With regard to measurement equivalence, findings appear to …

Adherent Cu films were electrodeposited onto polycrystalline W foils from purged solutions of 0.05 M CuSO4 in H2SO4 supporting electrolyte and 0.025 M CuCO3∙Cu(OH)2 in 0.32 M H3BO3 and corresponding HBF4 supporting electrolyte, both at pH = 1. Films were deposited under constant potential conditions at voltages between -0.6 V and -0.2 V versus Ag/AgCl. All films produced by pulses of 10 s duration were visible to the eye, copper colored, and survived a crude test called "the Scotch tape test", which involves sticking the scotch tape on the sample, then peeling off the tape and observing if the copper film peels off or not. Characterization by scanning electron microscopy (SEM)/energy dispersive X-ray (EDX) and X-ray photon spectroscopy (XPS) confirmed the presence of metallic Cu, with apparent dendritic growth. No sulfur impurity was observable by XPS or EDX. Kinetics measurements indicated that the Cu nucleation process in the sulfuric bath is slower than in the borate bath. In both baths, nucleation kinetics does not correspond to either instantaneous or progressive nucleation. Films deposited from 0.05 M CuSO4/H2SO4 solution at pH > 1 at -0.2 V exhibited poor adhesion and decreased Cu reduction current. In both borate and sulfate baths, small …

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 …

The United States is in the middle of a gripping nursing shortage; a shortage that is putting patients' lives in danger. This study determined the impact community and tribal colleges in severely economically distressed counties of the United States have on the nursing shortage faced by health care facilities serving these areas. The initial sample of 24 institutions selected in the Ford Foundation's Rural Community College Initiative (RCCI) (1995-2000). Data were collected from the Fall 1998 National Study of Post Secondary Faculty to obtain characteristics of faculty and from the 2003 Integrated Postsecondary Education Data System (IPEDS) to obtain characteristics of students, both at all publicly-controlled community colleges, all tribal colleges, and the 24 RCCI colleges that included 18 community and six tribal colleges. A survey was sent to the directors/deans/chairs of the nursing programs to ascertain issues related to the nursing program, nursing faculty, and nursing students. Respondents were asked to identify the healthcare facilities used for students' clinical experiences. A survey was then sent to each of these facilities asking about rural health, and source of nursing staff. Findings: 1) 87% of these these rural healthcare facilities are experiencing a significant shortage of nurses, and they are challenged …

William Grant Still's musical achievements are legion. Because he was the first African American to break the color line in America's concert halls, Still earned the sobriquet "Dean of Negro Composers." Paradoxically, Still's reception suffers from this list of "firsts." The unintended consequence of cataloging his achievements venerates his position as an iconoclast while detracting critical attention from his music. Conversely, if we ignore the social context in which Still produced his music, we risk misinterpreting his compositional choices or trivializing the significance of his accomplishments prior to the Civil Rights Movement in America. Still's so-called symphonic trilogy-Africa, Symphony No. 1 ("Afro-American"), and Symphony No. 2 ("Song of a New Race")-is the subject of an intertextual analysis that demonstrates how extra-musical concerns, such as race, and musical elements can be brought into alignment. Chapter one discusses black music scholarship in general and Still scholarship in particular by tracing the development of black music historiography. The second chapter explores one of the various modes of inquiry used to study black music-intertextuality. The context for Still's self-titled racial and universal periods is the subject of chapter three. For the first time, arguments from both sides of the racial divide are reconsidered in …

As a very promising material of copper diffusion barrier for next generation microelectronics, Ru has already obtained a considerable attention recently. In this dissertation, we investigated ruthenium and ruthenium oxide electrochemical properties and the application as a copper diffusion barrier. Cu under potential deposition (UPD) on the RuOx formed electrochemically was first observed. Strong binding interaction, manifesting by the observed Cu UPD process, exists between Cu and Ru as well as its conductive ruthenium oxide. Since UPD can be conformally formed on the electrode surface, which enable Ru and RuOx has a potential application in the next generation anode. The [Cl-] and pH dependent experiment were conducted, both of them will affect UPD Cu on Ru oxide. We also found the Cu deposition is thermodynamically favored on RuOx formed electrochemically. We have studied the Ru thin film (5nm) as a copper diffusion barrier. It can successfully block Cu diffusion annealed at 300 oC for 10min under vacuum, and fail at 450 oC. We think the silicidation process at the interface between Ru and Si. PVD Cu/Ru/Si and ECP Cu/Ru/Si were compared each other during copper diffusion study. It was observed that ECP Cu is easy to diffuse through Ru barrier. …

This study identified tenure policies and practices among Council for Christian Colleges & Universities (CCCU) member schools. A survey of CCCU member schools was conducted; 65 usable questionnaires were received. A response rate of 69% was achieved. Schools also provided portions of their faculty handbooks addressing tenure. The purpose of the study was to determine (a) what CCCU schools grant tenure, (b) why they grant tenure, (c) specific tenure policies and practices, (d) what CCCU schools do not grant tenure, (e) why they do not grant tenure, (f) retention policies used in place of tenure, and (g) how CCCU schools' tenure policies compare with the American Association of University Professors (AAUP) guidelines. The data suggests that (a) the majority of CCCU schools (68%) grant tenure, (b) these schools represent nearly all religious affiliations within the CCCU, and (c) they are large in relation to CCCU schools that do not grant tenure. The predominant reasons given for granting tenure are protection of academic freedom, mutual commitment by institution and faculty, and recruiting / retaining quality faculty. The schools grant tenure based on teaching, scholarship, service, and the integration of faith and learning. Tenure success rates seem high. Thirty-two percent of the …

This dissertation studies different social aspects of terrorists and terrorist organizations in an effort to better deal with terrorism, especially in the long run. The researcher, who also worked as a Police Captain at Turkish National Police Anti-Terrorism Department, seeks solutions to today's global problem by studying both literature and a Delphi examination of a survey of 1070 imprisoned terrorists. The research questions include questions such as "What are the reasons behind terrorism?", "Why does terrorism occur?", "What ideologies provide the framework for terrorist violence?, "Why do some individuals become terrorists and others do not?" and "Under what conditions will terrorists end their violence?" The results of the study presents the complexity of the terrorism problem as a social experience and impossibility of a single solution or remedy for the global problem of terrorism. The researcher through his examination of the findings of the data, presented that terrorism is a social phenomenon with criminal consequences that needs to be dealt by means of two dimensional approaches. The first is the social dimension of terrorism and the second is the criminal dimension of terrorism. Based on this, the researcher constructed a conceptual model which addresses both of these dimensions under the …

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.

EEG biofeedback (neurotherapy) has been demonstrated as effective in the treatment of alcoholism, as evidenced by Peniston and Kulkosky's research efforts. These neurotherapy pioneers evaluated the efficacy of alpha-theta brain wave biofeedback as a treatment for chronic alcohol abuse, citing 80% abstinence rates as measured by improvements in psychopathology, serum beta endorphin levels, and long-term alcohol abstinence. Most research with alpha-theta EEG biofeedback has addressed alcohol addiction. Cocaine is now considered to be the most common drug problem of patients entering treatment for drug abuse. To date, only one controlled study has been published that researched alpha-theta neurofeedback in the treatment of "crack" cocaine addiction. The present study was an extension of a 4-year EEG-biofeedback treatment outcome project underway at a faith-based homeless mission in Houston, Texas, with male "crack" cocaine addicts. Changes in personality, attention, and impulsivity were measured following 30 sessions of a non-individualized EEG -biofeedback protocol. Experimental subjects received a variant of the Peniston-Kulkosky alpha-theta protocol for 30 sessions while controls received all elements of the experimental protocol except the EEG biofeedback. Assessment measures included the MMPI-2 and the IVA. Although experimental subjects showed greater mean improvement on most MMPI basic scales and all IVA Attention related …
