African Refugee Parents' Involvement in Their Children's Schools: Barriers and Recommendations for Improvement: The purpose of this study was to examine involvement of African refugee parents in the education of their elementary school children. The setting of the study was Northern and Southern Texas. African refugee parents and their children's teachers completed written surveys and also participated in interviews. In the study's mixed-method design, quantitative measures provided data about parent involvement at home, parent involvement at school, frequency of parent-teacher contact, quality of parent-teacher relationship, parent endorsement of children's schools, and barriers to parent involvement. Qualitative data from the open-ended questions provided data on barriers and strategies to improve involvement. Sixty-one African refugee parents responded to the survey and also participated in an in-depth face-to-face or telephone interview. Twenty teacher participants responded to an online survey. Quantitative data gathered from the parent and teacher surveys were analyzed using frequency distributions and analyses of variance. Qualitative data were analyzed by summarizing and sorting information into different categories using Weft QDA, an open-source qualitative analysis software. From these data, I identified barriers to African refugee parent involvement in their children's schools, as well as challenges that teachers face as they try to involve African refugee parents. Results of analyses of variance revealed statistically significant differences in parent involvement between African refugee parents with limited English proficiency and those with high English proficiency. A key finding of the research was that, whereas the overall level of parent involvement for African refugee parents was low, a major barrier to involvement was language. Teachers and parents cited enrolment in English as a second language programs as the best strategy to enhance parent involvement of African refugees. Additionally, parents who reported higher education levels were more involved in their children's education both at home and at school. All groups of African refugee parents reported high endorsement of their children's …
Analysis of School Discipline with a Focus on Characteristics of Hispanic Adolescents with Learning Disabilities from a Low-Socioeconomic Area: The research reported herein examined the emotional and behavioral characteristics of adolescent Hispanic students with and without learning disabilities from a middle school in north central Texas. The data were based on all students enrolled at the campus (N = 986), but focused on 55 students of Hispanic descent with learning disabilities and 55 students without. The data accrued for this study utilized a school discipline database. In addition, a 43-item behavioral rating scale was completed on each student of the more focused group. Methods of data analysis were derived from descriptive statistics, one-way analysis of variance, and multiple regression measurements. The results indicate that Hispanic students with learning disabilities often exhibit more disruptive behaviors.
An Analytical Model of the Determinants and Outcomes of Nation Branding: Nation as a brand represents the intangible assets of a country, encompassing various dimensions such as politics, economics, culture, history, and technology. However, much of extant work in nation branding has been limited to the empirical investigations of its positioning and implementation for specific countries, while other scholarly works in nation branding are conceptual. Various factors associated with nation branding are discussed in the literature, but there is no organizing mechanism to connect these factors to explore the dynamics underlying nation branding. To fill this gap, this dissertation attempts to identify the relevant factors underlying the deployment of nation branding, and to develop models to assess the association among these factors. Hunt and Morgan's resource advantage theory serves as the theoretical foundation of this dissertation's framework. After establishing panel data models that link the factors of building and developing the nation brand, the strategic implications of nation branding are discussed. Archival data were used for economic factors such as economic development, tourism, export, and inward foreign investment, and cultural, political, infrastructural, and geographical factors. The primary data were collected for qualitative factors perceived reputable brand and perceived reputable industry. The Anholt-GfK Roper's 2008 Nation Brands IndexSM was incorporated into the model as a moderating variable to test its impact on the relationship between the dependent variables and the independent variables. A total of 24 nations were analyzed to build and validate the models. This dissertation makes several contributions to the nation branding literature. First, it clarifies the definition of nation brand and nation branding. Second, it builds a predictive econometric model to connect the critical determinant and outcome factors of nation branding. Finally, it discusses nation branding strategies in terms of resource advantage theory and provides crucial insights on the development and management of a nation brand that can be …
An Analytical Study: Applying Hindemith's Tonal Theory to Niels Viggo Bentzon's Third Piano Sonata, Op. 44: Niels Viggo Bentzon (1919-2000) is the most significant composer in the post-Nielsen period of Danish piano music. Bentzon's Third Piano Sonata, Op.44 was composed in 1946 and is considered by Mark L. Lehmann to be one of the great piano sonatas of the twentieth century. Not only does this sonata reflect Hindemith's ideas, but it also reveals Bentzon's unique style that successively empowers his innovative features. By applying Hindemith's theory, this study offers a way of understanding this piece and demonstrates the relevance of Hindemith's theory as a tool for analyzing the sonata. Chapter 1 presents the significance of the study, the state of research, the purpose of the study, and method. Chapter 2 provides a theoretical analysis of Bentzon's Third Piano Sonata, Op. 44. With a discussion of each movement, this analytical chapter traces Hindemith's influences: Bentzon organizes the four movements with a clear formal structure, a mediant relationship between the first movement and the rest of the movements, and a motivic coherence of each movement. Also, this chapter demonstrates how Bentzon follows Hindemith's way of chord construction and harmonic progression. This chapter provides insight into Bentzon's original style that facilitates an understanding of the tonal organization of each movement and illuminates Bentzon's intensity of expression through the use of quasi-improvisational passages, texture, dynamic fluctuations, and treatment of the full range of the piano. The last chapter concludes with a summary of Bentzon's compositional style based on observations from previous chapters.
Bidirectional Effects Between Engaged Lifestyle and Cognition in Later Life: Exploring the Moderation Hypothesis for Personality Variables.: Longitudinal data (N = 263) was used to investigate the bidirectional relationship between engagement (engaged lifestyle activities) and cognition (crystallized & fluid intelligence). Extroversion and openness to experience were also tested as moderators of the relationship between engagement and cognition. Results showed that the relationship between engagement at Wave 1 and cognition at Wave 2 did not differ from the relationship between cognition at Wave 1 and engagement at Wave 2. Testing for moderation with regression indicated that neither extroversion nor openness was moderating the relationship between engagement and cognition in either direction. Structural equation models provided further summary evidence that the relationships among engagement at Wave 1, extroversion, openness, and cognition at Wave 2 were not strong. However, a strong limitation to these results was the measurement error associated with a new measure of engagement.
Chamber Music with Double Bass: A New Approach to Function and Pedagogy.: The first part of the paper states the problem of the double bass not being incorporated into the chamber music program at many universities and the resulting lack of skills that can only be developed through this discipline. The double bass is trying to catch up with the other string instruments as it has been historically ignored, misunderstood and not as developed musically and technically. The historical background and current state of research are being examined to understand why this problem occurred in the first place, noting the vast amount of chamber music repertoire that is unknown and identifying some important but underperformed works. Further the pedagogical benefits of playing chamber music are discussed in order to realize the vital importance of integrating the double bass into the curriculum at major universities. Specific examples from the four major style periods are discussed in detail to show the benefits of studying this repertoire. Finally an implementation process is suggested to help change the current state of chamber music neglect as it pertains to the double bass.
Children's Spiritual Development: Analysis of Program Practices and Recommendations for Early Childhood Professionals.: The purpose of this study was to determine the extent to which faith-based preschools promote spiritual development in preschoolers. The participants in the study were faith-based early childhood teachers and administrators from seven states. Early childhood professionals representing 11 Christian faith traditions completed written surveys or online surveys. A total of 201 faith-based educators completed the survey; 20 respondents participated in semi-structured interviews. The concurrent triangulation mixed-method design provided data on 8 program dimensions which support children's spiritual development: prayer, Bible literacy, worship, building character, service opportunities, assessment, parental involvement and context. I analyzed quantitative data using descriptive and inferential statistics. All items were examined using mean, standard deviation, frequency, and percentages. Qualitative data gathered from semi-structured interviews were coded and analyzed using NVivo8® qualitative analysis software (QSR International, Inc., Cambridge, MA, http://www.qsrinternational.com). From this data I identified the extent to which faith-based preschool programs support children's spiritual development through the practices of prayer, Bible literacy, worship, building character, service opportunities, assessment, parental involvement and context. Data analyses revealed statistically significant differences in faith-based teachers' hours of training in children's spiritual development across all program practice dimensions. A key finding of the study was that training in children's spiritual development is important regardless of the education level of the early childhood professional. Qualitative data indicated no standardized spiritual development training in faith-based preschools represented in this study. The mixed-method analysis revealed that the 8 program practice dimensions were not always connected in a framework that supported children's spiritual development. Recommendations for professional practice include a program framework to support children's spiritual development in faith-based preschool programs; training for faith-based early childhood professionals in children's spiritual development; and formulating a definition of children's spiritual development.
Cultural and Technical Perspectives on Winter Landscape: Winter Landscape is an interactive composition for erhu (Chinese two-stringed fiddle), flute, piano, and Max/MSP interactive computer music system. The total duration of the piece is approximately 15 minutes. Winter Landscape serves to demonstrate one particular approach to exploring the possibilities afforded in an interactive paradigm within a cross-cultural context. The work is intended to convey my personality and identity as a contemporary Chinese composer through diverse cultural and musical influences drawn to this particular piece while creating a balance between traditional and modern sounds. The influences of Chinese philosophy (especially Chán) and the essence of Chinese traditional music play a prominent role as demonstrated in the formation of structures, expressions, and concept of Yun in the work; these influences also play a great role in determining the instrumentation and basic pitch structures of the work. However, this work is equally influenced by techniques and practices of modern Western classical music. These diverse influences hopefully have resulted in a unique work that truly does represent a cross-synthesis of these varying influences. In Winter Landscape, the interaction that takes place between the computer and the live musician is intended to reveal the responsive human/machine relationships. The computer constantly shifts its roles as a musical instrument, conductor, performer, and improviser to facilitate the sonic realization of the solemn, nebulous, and peaceful nature of Chán philosophy, thus exploring the cultural and musical potentials; meanwhile, the design of algorithmic structures simulate the modeling of human performance, enabling the computer with intellectual ability and musical expressivity as a decision-maker, resembling its counterpart-the live performer.
Cyberbullying: Responses of Adolescents and Parents toward Digital Aggression: Cyberbullying is a category of bullying that occurs in the digital realm which affects our students at astonishing rates. Unlike traditional bullying, where displays of aggression may be evident to bystanders, the ramification of cyberbullying occurs through unconventional ways (e.g., text messaging; online weblogs; video sharing), which results in many cases being camouflaged by the advancement in technology. Nonetheless, the effects of this digital form of peer aggression can be as detrimental as face-to-face bullying. The characteristics of cyberbullying and its influences on adolescents and parents of adolescents were examined. The data accrued is based on an anonymous survey through one of the following methods: (a) paper-pencil survey for adolescent group with 37-question items on the adolescent questionnaire and (b) web-based survey for the parent group with 22-question items on the parent questionnaire. Each survey was systematically coded according to the participating group and assigned code numbers (i.e., 1 represents adolescent group and 2 represents parent group) was provided to ensure confidentiality of the study. Survey examined individual variables among the two target groups: (a) adolescents between 13 and 17 years of age and (b) parents of adolescents between 13 and 17 years of age. Specifically, individual variables examined include (a) demographics, (b) personal experiences, (c) vicarious experiences, and (d) preventative resources. A total of 137 participants (62 adolescents; 75 parents) responded to the survey. Results indicated that 90% of the participants from the adolescent group have reported to experience either as victims or as bystanders of cyberbullying. In addition, 70% of the victims have been cyberbullied 1 to 2 times within a month period and 50% of the victims did not know the perpetrator. Secondly, 89% of parent participants indicated to be knowledgeable about the issues relating to cyberbullying and 89% reported to have no knowledge if their child …
Does the Knowledge of Unaudited Account Balances Adversely Affect the Performance of Substantive Analytical Procedures?: Auditors use substantive analytical procedures to make assertions about the adequacy and appropriateness of client balances. The analytical procedure process consists of auditors creating independent account expectations and corroborating unusual fluctuations through obtaining and evaluating additional audit evidence. Prior analytical procedure research has found that knowledge of clients' unaudited account balances biases auditors' expectations towards the current year figures. However, this research has failed to examine the impact of biased expectations on the subsequent stages of analytical procedures. This dissertation assesses the full impact of biased account expectations on auditors' use of analytical procedures. I experimentally test the hypotheses of my dissertation through administering an experiment to senior level auditors. After inducing an account expectation bias that favors the client account balance in half the participants, I examine the auditors' cognitive investigation into an unusual account fluctuation. The results indicate that a biased account expectation negatively affects auditors' judgment quality. In particular, a biased expectation leads auditors to favor hypotheses and additional information that supports the proposition that the client's balance is reasonably stated. Alternatively, auditors with unbiased account expectations are more willing to consider all hypotheses and are able to identify the most pertinent additional information to the decision task. As a result of the different decision strategies employed, auditors who form unbiased account expectations are significantly more likely than auditors with biased account expectations to identify the correct relationship among the underlying data and the proposed hypotheses during a substantive analytical procedure.
The Effectiveness of Business Leadership Practices among Principals on Student Achievement on Public School Campuses in Texas: The purpose of this descriptive study was to determine if business leadership practices by Texas public school principals have an impact on principals' campus student achievement in mathematics and reading, as measured by TAKS scores. The survey instrument was the Leadership Assessment Instrument (LAI), developed by Warren Bennis in 1989. The survey instrument was electronically distributed to a sample of 300 public school principals in Texas. Of the 300, 140 principals completed and returned the survey, for a response rate of 47%. The Statistical Package for the Social Sciences (SPSS), version 16.0, was used for the analysis of data, which included descriptive statistics, analysis of variance, and regression. In addition, reliability for the LAI was also calculated. The LAI consists of the following five categories of effective business practices: focused drive, emotional intelligence, building trust, conceptual thinking, and systems thinking. No significant relationships were found between principals' use of LAI elements and student achievement in mathematics and reading. However, the lack of significant relationships between the business model as used in public schools and student achievement reveals that current models of principal preparation programs do not result in school leaders who are adequately prepared to increase student achievement. Further research is recommended as public school leaders continue to seek alternative strategies and innovative practices to improve student achievement.
The Effects of Attendance at a Senior Center on the Quality of Life and Well Being of Grandparents Rearing Grandchildren.: The purpose of this study was to determine the effects of attendance at a senior center on the well being and quality of life of grandparents that were rearing grandchildren. Using convenience sampling, grandparents (N=130) who were rearing grandchildren were given a self administered demographic data survey along with an attendance at a senior center questionnaire, the Quality of Life Scale, the Well Being Scale by Liang, the UCLA Loneliness Scale, the Caregiver Burden Scale, and the Role Satisfaction Scale. An initial MANOVA (F 7, 69 = 2.72, p < .01) suggesting that senior center attendance affect the measures as a set was conducted and then a series of one way ANOVAs were carried out to test the hypothesis that attending a senior center has an effect on the dependent variables: well being, quality of life, role satisfaction, caregiver burden, loneliness, current health, and heath one year ago. Subsequently, a hierarchical regression analysis was conducted to find out whether frequency and quality of attendance of a senior center predicted quality of life, caregiver burden, well being, loneliness, and role satisfaction, controlling for the demographic data. The results of the MANOVA showed that the dependent variables: quality of life, caregiver burden, well being and role satisfaction were impacted positively by the attendance of a senior center. The results of the regression analyses showed that for each of the major dependent variables, after controlling for the demographic data, the quality and frequency of involvement at the senior center did not have a uniquely significant role in predicting the dependent variables. The results of this study shows that further research need to be conducted to answer other questions regarding grandparents who are rearing minor grandchildren and the affects that senior centers may have in assisting in the management of this new task that …
Effects of Background Music on Preschoolers' Attention.: Background music is often used in preschool classrooms with the belief that music makes children smarter and increases attention. The purpose of this study was to determine if background music increased children's focused attention during play activities. Focused attention occurs when children maintain attention to a task regardless of distractions. This quasiexperimental study investigated background music and play in a laboratory setting. I videotaped individual children during play with math manipulatives in a pretest-posttest research design with background music used as the treatment. Forty-three 3-, 4-, and 5-year-olds played for 15 minutes. The first 5 minutes of play had no music (pretest), the second 5-minute play episode had background music (treatment), and the final 5-minute play episode had no background music (posttest). Data were analyzed using one-way repeated measures analysis of variance. Findings revealed that the subjects paid less attention to the play task with background music than they did during the pretest, with no music. Another key finding was that children with more musical experiences at home, as reported by the Child's Home Musical Experience Survey (CHIMES), exhibited longer periods of focused attention with background music. This study confirmed previous research that 3-year-old children have shorter focused attention than 4- and 5-year-old children with and without background music. These findings have implications for teachers and parents that background music, instead of increasing attention in children, might indeed decrease children's focused attention during play activities.
An Evaluation Model for Identifying Lewisville and San Angelo, Texas, as Senior Ready Communities: This research portrays a paradigm for the assessment of aging services to support populations aging in place. The dissertation was designed to establish a model to identify and evaluate senior ready communities. Area specific social programs and services are identified. In order to meet the growing needs of aging populations, the dynamic representation of existing services and the need for services that could be developed in certain communities require reevaluation in current planning, restructuring, and/or community development.
Examining Career Transitions during Mid-Adulthood through the Lens of Bioecological and Microdevelopmental Research: Using hierarchical multiple linear regression, this study examined the predictive relationship between micro-career transitions and career related outcomes and how those relationships were moderated by equilibration style. Participants (n = 177) answered an online survey which included a variety of measures for control, predictor, moderator, and outcome criterion (i.e., demographic descriptors, Instrumentality, Openness, Job Insecurity, Social Support Satisfaction, Microtransitions, Equilibration Style, Job Satisfaction, Job Burnout, Life Dissatisfaction, and Career Optimism). Research questions addressed the nature of micro-career transitions (e.g., frequencies, average stress ratings, category types), their predictive relationship with job and career outcomes, and the moderating role of Identity Styles on that relationship. Micro-career transitions were described according to responses for the research sample (n = 638). Significant effects were discovered between microtransitions and career outcomes (p < .05 and .01). Equilibration styles were also established as having a moderating effect on the predictive relationship between microtransitions and career outcomes (p < .05 and .01). Interaction terms were decomposed to examine the direction of significant moderating effects. In all cases where interaction terms were significant, moderators enhanced the negative predictive relationship between microtransitions and career outcomes.
Factors of the Geriatric Depression Scale that may Distinguish between Four Cognitive Diagnostic Groups: Normal, Mild Cognitive Impairment, Dementia of the Alzheimer's Type, and Vascular Dementia: The purpose of the current study was to explore the relationship between cognitive status and depression in a sample of geriatric patients. Participants included 282 geriatric patients ranging in age from 65 to 96 years who were classified according to diagnosis as: DAT, VaD, MCI, and Norm. All were referred for neurocognitive testing from the Geriatric Assessment Program (GAP) at the University of North Texas Health Science Center (UNTHSC) in Fort Worth, Texas. This study sought to identify factor structures for two versions of the GDS using a geriatric sample of cognitively impaired and intact patients. It then compared these factors to each other to determine whether the GDS-15 is truly a shorter version of the GDS-30. These were then compared to a previously determined factor structure. This study explored whether the four-factors of the GDS-30 are able to differentiate cognitive diagnostic groups. Further, this study sought to identify whether the severity of cognitive decline impacted GDS factor score for each of the cognitively impaired groups. Results revealed a two-factor model of the GDS - 15 and a four-factor model with the GDS - 30. The GDS-15 factors did not differ from the first two factors of the GDS-30. Comparison between the GDS-30 factor structure and that reported by Hall and Davis (in press) revealed no significant differences despite the inclusion of a normal, non-demented group in the current study. Comparisons of subscale scores revealed that DAT patients tended to score lower than the other groups on all but the cognitive impairment subscale. Severity level analyses indicated that as severity of deficits increases, awareness of deficits decreases. This study found that although the GDS-30 is a good screening tool for depression in geriatric patients, it is not particularly useful in differentiating cognitive status group. Also, the GDS-15 was not found …
The Five Dimensions of Professional Learning Communities in Improving Exemplary Texas Elementary Schools: A Descriptive Study: This descriptive study investigated the development of the 5 dimensions of the professional learning community model in 5 economically disadvantaged and diverse Texas elementary schools, which demonstrated improvement in student achievement on the Texas Assessment of Knowledge and Skills (TAKS) over a 5-year period. Each of the schools were given the highest performance rating of Exemplary during the 2008 school year according to criteria developed by the Texas accountability system and had changed from an Acceptable rating in 2004. The purpose of this study was to determine the level of the development of the 5 dimensions of the professional learning community model in improving exemplary Texas elementary schools and to identify and compare the possible commonalities and differences existing between the schools on the 5 dimensions of professional learning communities. The 5 dimensions of the professional learning community model investigated in this study include: 1) shared and supportive leadership, 2) shared values and vision, 3) collective learning and the application of learning, 4) shared personal practice and 5) supportive conditions (collegial relationships and structures). The method used in this study was a mixed method approach that employed a questionnaire, individual principal and teacher interviews and school performance documents to collect data. The questionnaire data was analyzed through descriptive and analytical statistics while the interviews were investigated by identifying and documenting emergent patterns and themes. The findings from this study suggest that sustainable professional learning communities are evident in the high performing schools selected for this study. The study implies the culture of these schools is supported by relationships fostered by trust and mutual respect and their success is attributed to the collaborative, collegial and collective learning of the staff. Staff members from these schools are focused on student learning while campus leadership, grade level and vertical teams provide the structures …
Health Status and Access Disparities Among the Uninsured Working-Age Population in a Safety-Net Healthcare Network in Tarrant County, Texas: The objective of this research was to determine if healthcare access disparities exist across race and gender in a publically funded safety-net healthcare system in Texas. Data were examined from a representative random sample of 1468 adults aged 18-64 who were patients in this safety-net system in July and August of 2000 and were analyzed using binary logistic regression and chi-square measures of significance. Major Findings: On measures of health status - overall health rating (p =.051), limited employment (p =.000), energy level (p =.001), and worry (p =.012) - Anglos reported the worst health; Mexican Americans, the best health; with African Americans intermediate. Mexican Americans were more likely to have never had health insurance, and to also have had insurance in the past year; Anglos were least likely to have ever had insurance (p =.015) or to have had insurance in the past year (p =.000). On use of EDs (p =.028), problems getting prescription medicines (p =.029), and foregoing other necessities of life to pay for healthcare, Mexican Americans were least disadvantaged with African Americans reporting greatest use of EDs among both men and women, and Anglos the most problems with prescription medicines and foregoing care, especially among women. Logistic regression revealed that health status was the strongest predictor of problems accessing healthcare in all groups; the poorer health status of safety-net patients, the more problems they had accessing care. Patterns of poor reported health status and greater problems accessing care among Anglos relative to other groups is discussed in terms of social drift and relative deprivation.
Hypoxic and hyperoxic incubation affects the ductus arteriosus in the developing chicken embryo (Gallus gallus).: Developing chicken embryos have two ductus arteriosus (DA) that shunt blood away from the lungs and to the chorioallantoic membrane, the embryonic gas exchanger. In mammals, DA closure is stimulated by an increase in blood gas O2 that occurs as the animal begins to breathe with its lungs. The goal of this study was to determine the influence of O2 levels during incubation on the vascular reactivity and morphology of the O2-sensitive DA and to examine the effects of changing O2 levels during late incubation on the morphology of the DA from chicken embryos. In comparison to normoxia, hypoxia (15%) reduced venous O2 levels in day 16 and day 18 embryos and reduced aircell O2 values in day 16, day 18, and internally pipped (IP) embryos, whereas hyperoxia (30%) increased venous O2 levels and aircell O2 level in day 16, day 18, and IP embryos. In comparison to normoxia, hypoxia delayed closure of the DA, whereas hyperoxia accelerated DA closure. In comparison to the left DA from externally pipped (EP) normoxic embryos, the left DA from EP hypoxic embryos exhibited a significantly weaker contractile response to O2. The DA from day 18 hypoxic embryos exhibited a significantly weaker contractile response to norepinephrine and phenylephrine when compared with the DA from day 18 normoxic and hyperoxic embryos. The effect of incubation in hypoxia / hyperoxia during different developmental windows on the DA O2-induced contractile response was observed only in IP embryos that were incubated in normoxia for 16 days and were then moved to hyperoxia. Incubation in hypoxia / hyperoxia resulted in differences in embryo mass, yolk mass, and heart mass. There is an association between the decreased contractile response to O2 and delayed closure in the proximal portion of the DA from hypoxic embryos; as well as an increased contractile …
Identity Issues in Asian-American Children's and Adolescent Literature (1999-2007): Published research suggests that literature should transmit ethnic and societal values as well as reassure one's own confidence and self-respect. This study provides a model for examining Asian-American children's and adolescent literature critically from the perspective of identity issues. It examines fifteen award-winning Asian-American children's and adolescent titles written by writers of that culture and published in the United States from 1999 to 2007, with a focus on Chinese (Taiwanese) American, Korean American, and Japanese American books. As published studies indicate, self, social, and ethnic identities are significantly intertwined. Hence, a content analysis was conducted based on these three major groups of categories. The findings of the study demonstrate that even though the selected books cover all three aspects of the identity issues to a certain degree, a considerably greater number of depictions of ethnic identities are made over those of internal identities and social identities. Moreover, less than half of the main characters assume an active role in improving the difficult situation. Two major voids regarding the presentation of social identities are successful social integration and positive social interactions. Recommendations for teaching, writing, illustrating, publishing, and future research are suggested, including publishing more Asian-American books which present an optimistic outlook on life, active conflict-resolving behaviors, and a balance of gender among individuals with whom the main character interacts.
Impact of Forecasting Method Selection and Information Sharing on Supply Chain Performance.: Effective supply chain management gains much attention from industry and academia because it helps firms across a supply chain to reduce cost and improve customer service level efficiently. Focusing on one of the key challenges of the supply chains, namely, demand uncertainty, this dissertation extends the work of Zhao, Xie, and Leung so as to examine the effects of forecasting method selection coupled with information sharing on supply chain performance in a dynamic business environment. The results of this study showed that under various scenarios, advanced forecasting methods such as neural network and GARCH models play a more significant role when capacity tightness increases and is more important to the retailers than to the supplier under certain circumstances in terms of supply chain costs. Thus, advanced forecasting models should be promoted in supply chain management. However, this study also demonstrated that forecasting methods not capable of modeling features of certain demand patterns significantly impact a supply chain's performance. That is, a forecasting method misspecified for characteristics of the demand pattern usually results in higher supply chain costs. Thus, in practice, supply chain managers should be cognizant of the cost impact of selecting commonly used traditional forecasting methods, such as moving average and exponential smoothing, in conjunction with various operational and environmental factors, to keep supply chain cost under control. This study demonstrated that when capacity tightness is high for the supplier, information sharing plays a more important role in effective supply chain management. In addition, this study also showed that retailers benefit directly from information sharing when advanced forecasting methods are employed under certain conditions.
The Impact of Legal Sanctions on Recidivism Rates among Male Perpetrators of Domestic Violence: Using a Cox proportional hazards regression model, this dissertation explores three factors currently not addressed in the literature on men who batter women and who are court ordered to participate in a battering intervention program. These factors are the cumulative effects of civil and criminal legal sanctions (dose-response of sanctions) for domestic violence related offenses on recidivism, reduced opportunities to recidivate, and whether the number of legal sanctions imposed has an effect on how long a man maintains his non-recidivism status. Because one domestic violence case may involve multiple sanctions, this study uses the Legal Sanction Dose-Response Index to gauge the cumulative impact of civil and criminal sanctions upon recidivism of domestic violence. The Cox proportional hazards model indicates that the risk of recidivism is 45% lower for men who experienced two legal sanctions (typically arrest and probation) in response to the index case, relative to men who experienced one legal sanction (typically civil protective order). In other words, those with two legal sanctions are able to maintain their non-recidivism status longer relative to those with one sanction. Men with prior criminal court involvement for domestic violence related offenses are more likely to recidivate. Additionally, rather than incarceration reducing opportunities to recidivate, this study finds that incarceration for any offenses committed during the follow-up period is a predictor of recidivism of domestic violence related offenses. It is possible that, rather than incarceration reducing opportunities, recidivists are persistent and use whatever opportunities are available to them to commit domestic violence, despite legal sanctions.
The Impact of Surveillance Technology on the Behaviors of Municipal Police Departments: Citizen complaints about inappropriate use of force indicate negative police-public relations, unresponsive police services, and the unresponsiveness of police management to citizens' concerns. However, the effective delivery of key policing services depends on the performance of individual police officers. Surveillance technology can monitor and control the behavior of officers, ensuring that police officers provide high quality policing services that meet the needs of citizens. Examples of surveillance technology such as in-car cameras and CCTV can be used as an administrative tool to respond to citizen complaints by police chief executives. This research examines the effect of surveillance technology on the behavior of municipal police departments that is operationalized as the number of citizen complaints that were filed against municipal police departments. This research also examines the impact of surveillance technology on dismissed and sustained complaints by using 511 large municipal police departments in the U.S. from Law Enforcement Management and Administrative Statistics (LEMAS) 2003 dataset. Three different models are developed to evaluate the impact of in-car cameras and CCTV on the citizen complaints and their dispositions. Two ordinary least square regression (OLS) models and a Heckman selection model are used to analyze the data. The Heckman selection model is utilized to correct for selection bias in truncated data for sustained complaints after log transformation. The results suggest that the use of surveillance technology by the police is necessary, but insufficient, in reducing the number of complaints. The finding suggests that videotaped evidence, recorded by surveillance technology, increased the number of convictions of accused officers in municipal police departments. The analysis also suggests that municipal police departments that used CCTV only in 2003 received a higher number of citizen complaints, in comparison to municipal police departments without CCTV, both in 2000 and 2003. No evidence was found to indicate that surveillance …
In vitro Cultures of Morus alba for Enhancing Production of Phytoestrogens: Plant estrogens have long been associated with health benefits. The potential of tissue culture techniques for the production of several secondary metabolites has been known for many years. Tissue cultures stimulate the production or induce the biosynthesis of novel compounds not found in the mature plant. Tissue culture of Morus alba, family Moraceae, is known to contain phytoestrogens, was established on plant-hormone supplemented Murashige and Skoog (MS) medium. Petiole and the stem tissue from mature trees were the best explants for initiation and proliferation of calli. The best callus proliferation was obtained on MS medium containing 1-napthalene acetic acid (1mg/ml) and benzylaminopurine (0.5mg/ml) for M. alba. Comparison of phytoestrogens of Moraceae species from in vivo and in vitro tissue isolation were carried out. The estrogenic activities of callus extracts were assayed in an estrogen-responsive yeast system expressing the human estrogen receptor alpha. Male callus extracts had higher estrogenic activity than male and female extracts from in vivo and in vitro tissues. Isolation and characterization of phytoestrogens from above tissues were carried out using solid phase extraction, high perfomance liquid chromatography and mass spectrometry techniques. Biochanin A, an isoflavonoid, was isolated as one of the compounds in male callus extracts. Biochanin A has been known to have an antiestrogenic acitivity in mammals. Isoflavonoid compounds have been characterized as strong protein tyrosine kinase inhibitors in variety of animal cells. Isoflavones are structurally similar to estradiol, and display agonistic and antagonistic interactions with the estrogen receptor. Isoflavones possess therapeutic and preventive properties such as being used for postmenopausal osteoporosis, breast cancer, and inhibition of tumors.
Inferring Social and Internal Context Using a Mobile Phone: This dissertation is composed of research studies that contribute to three research areas including social context-aware computing, internal context-aware computing, and human behavioral data mining. In social context-aware computing, four studies are conducted. First, mobile phone user calling behavioral patterns are characterized in forms of randomness level where relationships among them are then identified. Next, a study is conducted to investigate the relationship between the calling behavior and organizational groups. Third, a method is presented to quantitatively define mobile social closeness and social groups, which are then used to identify social group sizes and scaling ratio. Last, based on the mobile social grouping framework, the significant role of social ties in communication patterns is revealed. In internal context-aware computing, two studies are conducted where the notions of internal context are intention and situation. For intentional context, the goal is to sense the intention of the user in placing calls. A model is thus presented for predicting future calls envisaged as a call predicted list (CPL), which makes use of call history to build a probabilistic model of calling behavior. As an incoming call predictor, CPL is a list of numbers/contacts that are the most likely to be the callers within the next hour(s), which is useful for scheduling and daily planning. As an outgoing call predictor, CPL is generated as a list of numbers/contacts that are the most likely to be dialed when the user attempts to make an outgoing call (e.g., by flipping open or unlocking the phone). This feature helps save time from having to search through a lengthy phone book. For situational context, a model is presented for sensing the user's situation (e.g., in a library, driving a car, etc.) based on embedded sensors. The sensed context is then used to switch the phone into a suitable …
The Influence of Giovanni Bottesini (1821-1889) on Pedro Valls (1869-1935): An Analysis of Homenaje à Bottesini (1906) by Pedro Valls: This document traces a link between Pedro Valls and Giovanni Bottesini by identifying traits of Homenaje à Bottesini that resemble techniques and musical characteristics of Bottesini's music, through the comparison of Valls' Homenaje à Bottesini to Bottesini's Fantasia sur La Sonnambula, focusing on the works formal, musical and idiomatic characteristics. This is supported by documented evidence of Bottesini's presence in Spain during Valls's lifetime and Pedro Valls contact with the Italian master of the double bass school of playing and teaching method. This study also proposes adjustments in the notation of Homenaje à Bottesini to more modern and player-friendly score indications, which will help its inclusion into the active double bass repertoire. This document examines performance practice(s) of the work and what advantages or disadvantages these practices have in playing the work, and to ultimately offer a clear pathway, a road map, to performers interested in delving into Pedro Valls's work, with a better idea of what Valls's style consists of and what approach to take when performing his works.
Intertextualization: An historical and contextual study of the battle villancico, El más augusto campeón.: This document addresses the cultural and significance of the battle villancico, El más augusto campeón, and its historical, social, and musical contexts within the villancico genre of the Latin American Baroque. This study focuses on the villancico, El más augusto campeón, and explores the possible origins of the text and its relevance to the political and social structure of Cuzco's San Antonio Abad Seminary. Other areas of investigation are the musical analysis of the score and performance practice issues that surface when making choices as a conductor. Considering the seminal position villancicos held in the catechization of the Incans, in part due to their popular nature, the study of a representative example of this significant genre lends further insight into how important the villancico was to the ordinary and feast services of Peruvian (and, by association, Latin American) churches. While within the villancico's textual and musical structure one reads the obvious reflection of peninsular Spanish Catholic culture, its application to the criollo subculture carries an even more striking relevance.
An Investigation Into the Factors Leading to the Closure of 40 Private Four-Year Colleges between 1965 and 2005: This study searches for a set of common indicators that contributed to the ultimate closure of 40 colleges and universities between 1965 and 2005. From research on related literature, a set of 31 contributing factors was identified by published experts and observers in higher education. That set of indicators was then used as a list of 31 questions answered by data found in newspaper articles, professional journals, published research work, published institutional records, data taken from the Department of Education, data taken from IPEDS, data published in historical recounts of the colleges of interest, etc. The data was accumulated in the form of yes/no responses to the 31 questions. Although the study involved only 40 colleges and universities this population represents the majority of institutions that pass the restrictions of limitations and delimitations described in the full document. The complete data set was processed using SPSS which produced ANOVA tables and level of statistical significance for each indicator question. The results indicate that out of the 31 original indicator questions there were two groups of statistically significant indicators. The larger group of indicators having statistical significance at the .05 level encompassed the smaller group having statistical significance at the .001 level. There were ten indicators in the first group with significance at the .05 level and seven in the second group with significance at the .001 level. Both groups conform to Bowen's revenue theory of cost associated with the operations of colleges and universities. The first group also has a cultural values component observed by a number of the experts cited in this study. The second is very tightly associated with Bowen's revenue theory of cost and Bates and Santerre's for profit theory of economics. Future research needs to be done to investigate the effect of such use of those …
Latent Transition Analysis of Pre-service Teachers' Efficacy in Mathematics and Science: 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.
Laying the foundation for successful non-academic writing: Professional communication principles in the K-5 curricula of the McKinney Independent School District.: Traditionally, K-5 students' writing has had a primarily academic aim-to help students master concepts and express themselves. Even if students take a professional writing course later, they typically do not have the opportunity to practice-over the long period of time mastery requires-the non-academic writing skills they will be required to use as part of their jobs and in their civic life. Based on a limited K-5 study, Texas' McKinney Independent School District is doing a good job of preparing students at the elementary-school level in the areas of collaboration and presentation. A fair job of helping elementary-school students understand the communication situation, define audience, clarify purpose, gather and evaluate resources, and test usability. [And] a poor job of helping elementary-school students with analysis and organization. With their teachers' help, K-5 students eventually grasp the communication situation and can broadly identify their audience and purpose, but they do not appear to select words, format, communication style, or design based on that audience and purpose. Their writer-based focus affects their presentations as well, although they do present frequently. If teachers routinely incorporated audience and purpose considerations into every aspect of communication assignments (format, communication style, design), students would be better prepared for non-academic communication. Texas pre-service teachers practice the types of documents they will write on the job but do not receive training in design or style. Likewise, they practice researching, collaborating, and presenting but receive little training in those skills. If Texas K-5 teachers are to supplement the curriculum with professional writing principles, as trends suggest they should, education programs need to focus on these principles in their pre-service teacher curriculum. Professional writing principles need to become part of ingrained writing patterns because these are the skills that will best serve students after they graduate, both in their careers and civic …
Letters, Liberty, and the Democratic Age in the Thought of Alexis de Tocqueville: When Alexis de Tocqueville observed the spread of modern democracy across France, England, and the United States, he saw that democracy would give rise to a new state of letters, and that this new state of letters would influence how democratic citizens and statesmen would understand the new political world. As he reflected on this new intellectual sphere, Tocqueville became concerned that democracy would foster changes in language and thought that would stifle concepts and ideas essential to the preservation of intellectual and political liberty. In an effort to direct, refine, and reshape political thought in democracy, Tocqueville undertook a critique of the democratic state of letters, assessing intellectual life and contributing his own ideas and concepts to help citizens and statesmen think more coherently about democratic politics. Here, I analyze Tocqueville's critique and offer an account of his effort to reshape democratic political thought. I show that through his analyses of the role of intellectuals in democratic regimes, the influence of modern science on democratic public life, the intellectual habits that democracy fosters, and the power of literary works for shaping democratic self-understanding, Tocqueville succeeds in reshaping democratic language and thought in a manner that contributes to the preservation of intellectual and political liberty within the modern democratic world.
Level Curves of the Angle Function of a Positive Definite Symmetric Matrix: 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.
A Longitudinal Examination of Factors Associated with Custodial Grandparenting: A Test of Moderated Mediation: The purpose of this study was to explore the following relationships: (a) how moderating factors (gender, age, ethnicity, social support, marital status, reason for role assumption and number of grandchildren in the home) can influence the mediating role of resiliency, and (b) how resiliency may mediate the negative effects of raising grandchildren (role demands, life disruptions, and difficulties with grandchildren) on grandparent adjustment over time. Resiliency was hypothesized to have the greatest effect on custodial grandparents who experienced the most stress (i.e., older, single, Caucasian males lacking social support and raising more than one grandchild). Mediation was assessed using structural equation modeling. Results indicated resilience mediated the relationship between role assumptions (i.e., role demands and life disruptions) and grandparent adjustment; however, resilience did not mediate the relationship between grandchild characteristics and grandparent adjustment. Due to the small number of custodial grandfathers (n = 14), non-married grandparents (n = 29), non-Caucasian grandparents (n = 10), the small number of grandparents who assumed the custodial role for less ambiguous reasons (n = 24), and the number of custodial grandparents with more than one grandchild residing in the home (n = 29) participating within the study, hierarchical multiple regressions were only conducted to test for moderated mediation for perceived social support and the age of the grandparent. Results indicated resilience mediates the relationship between life disruption and grandparent well-being for younger custodial grandparents and for custodial grandparents with perceived high social support.
The Map and the Territory in the Poetry of Wallace Stevens: In this dissertation, Wallace Stevens' imagination-reality problem as depicted in his poetry is discussed in terms of an eco-critical map-territory divide. Stevens's metaphor of "the necessary angel" acts to mediate human necessity, the map, with natural necessity, the territory, in order to retain contact with changing cultural and environmental conditions. At stake in this mediation are individual freedom and the pertinence of the imagination to the experience of reality. In Chapter 2, the attempt at reconciliation of these two necessities will be described in terms of surrealism. Stevens's particular approach to surrealism emphasizes separating and delineating natural necessity from human necessity so that through the poem the reader can experience the miracle of their reconciliation. In Chapter 3, this delineation of the two necessities, map and territory, will be examined against Modernist "decreation," which is the stripping bare of human perception for the purpose of regaining glimpses of the first idea of the external world. And in Chapter 4, Stevens's approach to the problem of the map-territory divide will be considered against his alienation or internal exile: balancing nature and identity through mediating fictions results in a compromised approach to the marriage of mind and culture in a historically situated place.
Metabolic, cardiac and ventilatory regulation in early larvae of the South African clawed frog, Xenopus laevis.: Early development of O2 chemoreception and hypoxic responses under normoxic (150 mmHg) and chronically hypoxic (110 mmHg) conditions were investigated in Xenopus laevis from hatching to 3 weeks post fertilization. Development, growth, O2 consumption, ventilatory and cardiac performance, and branchial neuroepithelial cells (NEC) density and size were determined. At 3 days post fertilization (dpf), larvae started gill ventilation at a rate of 28 ± 4 beats/min and showed increased frequency to 60 ± 2 beats/min at a PO2 of 30 mmHg. Also at 3 dpf, NECs were identified in the gill filament buds using immunohistochemical methods. Lung ventilation began at 5 dpf and exhibited a 3-fold increase in frequency from normoxia to a PO2 of 30 mmHg. Hypoxic tachycardia developed at 5 dpf, causing an increase of 20 beats/min in heart rate, which led to a 2-fold increase in mass-specific cardiac output at a PO2 of 70 mmHg. At 10 dpf, gill ventilatory sensitivity to hypoxia increased, which was associated with the increase in NEC density, from 15 ± 1 to 29 ± 2 cells/mm of filament at 5 and 10 dpf, respectively. Unlike the elevated rate, cardiac and ventilatory volumes were independent of acute hypoxia. Despite increased cardioventilatory frequency, larvae experienced an average of 80% depression in during acute hypoxia. Chronic hypoxia (PO2 of 110 mmHg) decreased mass-specific cardiac performance before 10 dpf. In older larvae (10 to 21 dpf), chronic hypoxia decreased acute branchial and pulmonary hypoxic hyperventilation and increased NEC size. Collectively, these data suggest that larvae exhibit strong O2-driven acute hypoxic responses post-hatching, yet are still O2 conformers. All acute hypoxic responses developed before 5 dpf, and then the effects of chronic hypoxia started to show between 7 and 21 dpf. Thus, the early formation of acute hypoxic responses is susceptible to the environment and can …
Moderators of the sociocultural internalization-body dissatisfaction relationship among female undergraduates.: The sociocultural model of eating pathology is an empirically-supported model explaining eating disorder etiology. The model poses that body dissatisfaction and subsequent eating pathology stems from the unrealistic standards formulated by Westernized society. Although the model has strong empirical support, variables within the model do not account for 100% of the variance in disordered eating. Thus, the current researcher attempted to explore potential moderating factors in the sociocultural model of eating disorders that may help to explain variance currently unaccounted for. In particular, the researcher focused on the relationship between sociocultural internalization and body dissatisfaction, given that this relationship has not been previously explored within the literature. Based on theoretical support, the researcher chose several potential variables to test, including perfectionism, neuroticism, body surveillance, and shame. Primary analyses tested each variable for moderating effects using hierarchical moderated regression, but no significant findings were shown. Results of post hoc analyses showed all variables had significant mediating effects, with the exception of self-oriented perfectionism. The discussion section addresses consistency with previous research, limitations of the present study, treatment implications and guidelines for future research.
Monitoring or moral hazard? Evidence from real activities manipulation by venture-backed companies.: Prior literature suggests two competing theories regarding the role of venture capitalists (VCs) in their portfolio companies. The VC monitoring hypothesis argues that VCs effectively resolve the managerial agency problem through close monitoring and restraining managers' earnings management behavior. The VC moral hazard hypothesis argues that VCs aggravate the private benefits agency problem by exerting influence over managers to artificially inflate exit stock price through earnings management. Using a sample of IPO firms between 1987 and 2002, after controlling for the magnitude of accruals manipulation (AM), I compare the magnitude of real activities manipulation (RM) between venture-backed and non-venture-backed companies. I find that relative to non-venture-backed companies, venture-backed companies show significantly less RM in the first post-IPO fiscal year. The results are robust after controlling for the VC selection endogeneity. The finding supports the VC monitoring hypothesis that VCs restrain managers' RM behavior. Furthermore, I document that venture-backed companies exhibit a significant difference from non-venture-backed companies only in the first post-IPO fiscal year. The difference between the two groups in either the IPO year or the second post-IPO fiscal year is not significant, or at best, is weak. This finding is consistent with the argument that VCs tighten their control during the lockup expiration period when insiders such as managers or founders have strong incentives to inflate earnings. By the end of the second post-IPO fiscal year when VCs exit the portfolio companies, their impact on portfolio companies' RM decreases dramatically which makes the difference between the two groups less significant. In addition, using a sample of venture-backed IPOs from 1987 to 2002, I find that companies backed by high-reputation VCs show significantly less RM than those backed by low-reputation VCs in the first post-IPO fiscal year. The results are robust to alternative VC reputation proxies. This finding is consistent …
Needs and Membership in Terrorist Organizations: One key to reducing terrorism may be to understand why individuals join terror groups, and to find ways to meet their needs through alternatives to discourage membership in terrorist organizations. The study introduces the hierarchy of needs framework to capture all previous pieces of explanations on why individuals join terror groups under one big umbrella, in order to see the big picture. It does not do a meta-analysis, but rather tests the framework. This study is designed to find out what perceived needs commonly motivate individuals to join terror groups in general and specific terror groups in particular. The research uses Turkey's terrorism experience as a case study which is supported with data from real terrorist in Turkey. Findings of the descriptive analyses show that majority joined a terror group due to social and affiliative needs. The remaining analyses (bivariate, cross-tabulation and binary logistic regression) show that confitents who perceived esteem and recognition were more likely to become members of other/leftist terror groups, and that rightist terror group members in Turkey tend to have higher education. Education mainly affects a confitent's perception of two needs: social and affiliation and self-actualization. Other demographic variables (age group, region of birth, marital status) die not yield any significant relation with membership in terror groups.
Negative affect and positive symptoms of psychosis.: The current study utilized structural equation modeling (SEM) to examine the factor-to-factor relations and temporal associations between disturbances in negative affect (NA) and positive symptoms of psychosis (PP). Data were drawn from a large, public-domain data set (MacArthur Violence Risk Assessment Study). A dimensional approach was used to conceptualize and identify latent variables of NA (depression, anxiety, and guilt) and PP (hallucinations, delusions, and thought disorder) among individuals with a diagnosis of primary psychotic disorder. Results showed that anxiety, guilt, and depressed mood modeled an NA latent variable, and that hallucinations and unusual thought content modeled a PP latent variable. As predicted, results revealed strong, significant cross-sectional (synchronous) associations between NA and PP at each measured time-frame, suggesting that NA and PP occurred concurrently within the sample. Contrary to predictions, no significant cross-lagged effect between NA and PP was identified (10 weeks and 20 weeks respectively).
Negotiating Interests: Elizabeth Montagu's Political Collaborations with Edward Montagu; George, Lord Lyttelton; and William Pulteney, Lord Bath: This dissertation examines Elizabeth Robinson Montagu's relationships with three men: her husband, Edward Montagu; George Lyttelton, first baron Lyttelton; and William Pulteney, earl of Bath to show how these relationships were structured and how Elizabeth Montagu negotiated them in order to forward her own intellectual interests. Montagu's relationship with her husband Edward and her friendships with Lord Lyttelton and Lord Bath supplied her with important outlets for intellectual and political expression. Scholarly work on Montagu's friendships with other intellectual women has demonstrated how Montagu drew on the support of female friends in her literary ambitions, but at the same time, it has obscured her equally important male relationships. Without discounting the importance of female friendship to Montagu's intellectual life, this study demonstrates that Montagu's relationships with Bath, Lyttleton, and her husband were at least as important to her as those with women, and that her male friendships and relationships offered her entry into the political sphere. Elizabeth Montagu was greatly interested in the political debates of her day and she contributed to the political process in the various ways open to her as an elite woman and female intellectual. Within the context of these male friendships, Montagu had an opportunity to discuss political philosophy as well as practical politics; as a result, she developed her own political positions. It is clear that contemporary gender conventions limited the boundaries of Montagu's intellectual and political concerns and that she felt the need to position her interests and activities in ways that did not appear transgressive in order to follow her own inclinations. Montagu represented her interest in the political realm as an extension of family duty and expression of female tenderness. In this manner, Montagu was able to forward her own opinions without appearing to cross conventional gender boundaries.
"Now His Time Really Seems to Have Come": Ideas about Mahler's Music in Late Imperial and First Republic Vienna: In Vienna from about 1918 until the 1930s, contemporaries perceived a high point in the music-historical significance of Mahler's works, with regard to both the history of compositional style and the social history of music. The ideas and meanings that became attached to Mahler's works in this milieu are tied inextricably to the city's political and cultural life. Although the performances of Mahler's works under the auspices of Vienna's Social Democrats are sometimes construed today as mere acts of political appropriation, David Josef Bach's writings suggest that the innovative and controversial aspects of Mahler's works held social value in line with the ideal of Arbeiterbildung. Richard Specht, Arnold Schoenberg, and Theodor Adorno embraced oft-criticized features in Mahler's music, regarding the composer as a prophetic artist whose compositional style was the epitome of faithful adherence to one's inner artistic vision, regardless of its popularity. While all three critics addressed the relationship between detail and whole in Mahler's music, Adorno construed it as an act of subversion. Mahler's popularity also affected Viennese composers during this time in obvious and subtle ways. The formal structure and thematic construction of Berg's Chamber Concerto suggest a compositional approach close to what his student Adorno described a few years later regarding Mahler's music.
Perceived Racial Discrimination and Psychiatric Outcomes among Asian Americans: The present study related generational status, family dynamics, and perceptions of racial discrimination (PRD) to acute psychiatric outcomes among a nationally representative Asian American sample (N = 2095), using data from the National Latino and Asian American Study (NLAAS). High self-reports of PRD were correlated with endorsement of clinical depression and suicidality as predicted. Regression analyses suggested that high PRD, low family cohesion, and high family conflict served as significant predictors of poor mental health independently, but moderator hypotheses predicting the interaction of these factors were not supported. Clinical and research implications are provided.
The perception of English language arts teachers about instructional changes following the implementation of the Texas Assessment of Knowledge and Skills test.: Accountability in education has been expanding for the past twenty years. As standards for curricular areas continued to develop, educational shareholders desired a way to measure student achievement contextualized by the established standards. Since 1964, policies expanded federal involvement with education, and with the No Child Left Behind Act in 2001, high-stakes testing became a significant part of public education. In Texas, testing transitioned in 2003 to the Texas Assessment of Knowledge and Skill (TAKS) test, an assessment that determines grade advancement for students, ratings for school districts, and additional compensation for some teachers. Along with the increasing expectations for student achievement, the need for effective instruction also increases. This dissertation studies how English language arts (ELA) teachers in four North Texas suburban high schools perceive instructional change following the implementation of TAKS. One hundred twenty-one teachers (n=121) were surveyed using an instrument broken into seven categories: student-centered instruction, student interest, instructional communication, time, classroom environment, teacher knowledge, and assessment. Participants were separated into two groups, teachers with one to six years of experience with a district or seven or more years with a district. Using a rating scale for each statement on the survey instrument, participants indicated the direction and magnitude of change or indicated no change occurred. When comparing an overall average frequency percentage for each possible rating for each category, the two highest percentages for both surveyed groups indicated no instructional change since the implementation of TAKS. However, when considering specific statements about professional growth and instructor knowledge, both groups were likely to rate a change as positive. Whereas, if the statement suggested instructional areas constricted by time, participants for both groups were likely to rate a change as negative. Additionally, an ANOVA indicated no significant difference between either of the participating groups.
Personal Properties: Stage Props and Self-Expression in British Drama, 1600-1707: This dissertation examines the role of stage properties-props, slangily-in the construction and expression of characters' identities. Through readings of both canonical and non-canonical drama written between 1600 and 1707-for example, Thomas Middleton's The Revenger's Tragedy (1607), Edward Ravenscroft's adaptation of Titus Andronicus (1678), Aphra Behn's The Rover (1677), and William Wycherley's The Plain Dealer (1677)-I demonstrate how props mediate relationships between people. The control of a character's props often accords a person control of the character to whom the props belong. Props consequently make visual the relationships of power and subjugation that exist among characters. The severed body parts, bodies, miniature portraits, and containers of these plays are the mechanisms by which characters attempt to differentiate themselves from others. The characters deploy objects as proof of their identities-for example, when the women in Behn's Rover circulate miniatures of themselves-yet other characters must also interpret these objects. The props, and therefore the characters' identities, are at all times vulnerable to misinterpretation. Much as the props' meanings are often disputed, so too are characters' private identities often at odds with their public personae. The boundaries of selfhood that the characters wish to protect are made vulnerable by the objects that they use to shore up those boundaries. When read in relation to the characters who move them, props reveal the negotiated process of individuation. In doing so, they emphasize the correlation between extrinsic and intrinsic worth. They are a measure of how well characters perform gender and class rolls, thereby demonstrating the importance of external signifiers in the legitimation of England's subjects, even as they expose "legitimacy" as a social construction.
Phosphorescent Emissions of Coinage Metal-Phosphine Complexes: Theory and Photophysics: The major topics discussed are all relevant to the bright phosphorescent emissions of coinage metal complexes (Cu(I), Ag(I) and Au(I)) with an explanation of the theoretical background, computational results and ongoing work on the application in materials and optoelectronic devices. Density functional computations have been performed on the majority of the discussed complexes and determined that the most significant distortion that occurs in Au(I)-phosphine complexes is a near and beyond a T-shape within the P-Au-P angle when the complexes are photoexcited to the lowest phosphorescent excited state. The large distortion is experimentally qualified with the large Stokes' shift that occurs between the excitation and emission spectra and can be as large as 18 000 cm-1 for the neutral Au(I) complexes. The excited state distortion has been thoroughly investigated and it is determined that not only is it pertinent to the efficient luminescence but also for the tunability in the emission. The factors that affect tunability have been determined to be electronics, sterics, rigidity of solution and temperature. The luminescent shifts determined from varying these parameters have been described systematically and have revealed emission colors that span the entire visible spectrum. These astounding features that have been discovered within studies of coinage metal phosphorescent complexes are an asset to applications ranging from materials development to electronics.
Physical Gesture, Spatialization, Form and Transformation in Watershed I/IV, for Solo Percussion and Real-time Computer Spatialization, by Roger Reynolds: Watershed I/IV, for Solo Percussion and Real-time Computer Spatialization was composed in 1995 by Pulitzer prize-winning composer Roger Reynolds. This work is a 25-minute choreographed music drama for one multiple-percussionist, in which Reynolds incorporates the musical transformation of percussion instrument families, the physical gestures of the performer, and the spatialization of processed sounds around the audience. This dissertation addresses several aspects of Watershed, which include: the expressive intent and extra-musical concepts; the formal organization, and several non-musical tools that Reynolds utilized in designing the piece (e.g. logarithmically derived sequences); the primary musical motives; the instrument setup and how the resulting physical gestures contribute to the musical intent; and the real-time computer spatialization. Throughout the document, specific musical passages are demonstrated with notated musical examples and embedded video/audio clips. In addition, transcripts of my interviews with composer Roger Reynolds, percussionist Steven Schick (premiere performer of Watershed) and engineer/technician Greg Dixon (engineer for my performances of Watershed IV) are also included.
The Politics of Sympathy: Secularity, Alterity, and Subjectivity in George Eliot's Novels: This study examines the practical and political implications of sympathy as a mode of achieving the intercommunicative relationship between the self and the other, emphasizing the significance of subjective agency not simply guided by the imperative category of morality but mainly enacted by a hybrid of discourses through the interaction between the two entities. Scenes of Clerical Life, Eliot's first fictional narrative on illuminating the intertwining relation of religion to secular conditions of life, reveals that the essence of religion is the practice of love between the self and the other derived from sympathy and invoked by their dialogic discourses of confession which enable them to foster the communality, on the grounds that the alterity implicated in the narrative of the other summons and re-historicizes the narrative of the subject's traumatic event in the past. Romola, Eliot's historical novel, highlights the performativity of subject which, on the one hand, locates Romola outside the social frame of domination and appropriation as a way of challenging the universalizing discourses of morality and duty sanctioned by the patriarchal ideology of norms, religion, and marriage. On the other hand, the heroine re-engages herself inside the social structure as a response to other's need for help by substantiating her compassion for others in action. Felix Holt, the Radical, Eliot's political and industrial novel, investigates the limits of moral discourse and instrumental reason. Esther employs her strategy of hybridizing her aesthetic and moral tastes in order to debilitate masculine desires for moral inculcation and material calculation. Esther reinvigorates her subjectivity by simultaneously internalizing and externalizing a hybrid of tastes. In effect, the empowerment of her subjectivity is designed not only to provide others with substantial help from the promptings of her sympathy for them, but also to fulfill her romantic plot of marriage.
Psychological Stress Reactivity and Recovery: The Role of Cognitive Appraisals, Ethnicity and Sex: The aim of this research was to investigate the role of sex, ethnicity and cognitive appraisals, separately and in combination, on the physiological stress response. One hundred and eight undergraduate students from two North Texas universities participated in the study. They were subjected to a laboratory stressor and heart rate, peripheral temperature and cortisol levels were measured pre-, during-, and post- stressor. Perceived stress and cognitive appraisals were measured via self-report. Multivariate analysis of variance tests were conducted to analyze the main and interaction effects during baseline, reactivity and post-stress recovery. Results indicated some significant main effects for sex and ethnicity but no consistent pattern of results or interactions among variables were revealed. The study's implications and areas of future research are discussed.
The relationship between computer-assisted instruction and alternative programs to enhance fifth-grade mathematics success on the annual Texas Assessment of Knowledge and Skills.: The purpose of this study was to determine the relationship between using computer-assisted instruction (CAI) and success on the Texas Assessment of Knowledge and Skills (TAKS) mathematics exam with fifth-grade students in Texas compared to the effect of alternative improvement approaches used by a control group. Research explored the use of SuccessMaker® CAI educational software (Pearson Education, Upper Saddle River, NJ, www.pearsoned.com) in public elementary schools in Texas. Successmaker® CAI was not a good predictor of passing percentage on the mathematics TAKS. Multiple regression analysis utilized in this quasi-experimental design study predicted a negative and not statistically significant change in the percentage of students passing the mathematics TAKS exam (B = -.448, p > .05). SuccessMaker® use exhibited a very small effect size (r = -.04) and accounted for less than 1% of the change in passing percentage (r2 = .0016).

Relationship between Fortune 500 companies with regulatory violations and/or criminal offenses and resulting stock values.: The purpose of this study was to determine whether publicly disclosed violations by U.S corporations, resulting in convictions or settlements, erode shareholder investment in the offending organizations. This study was designed to assess whether or not the shareholders' reactions to corporations' violations were related to a decline in organizations' stock valuations across sectors. In addition, this study attempted to assess whether or not shareholder support, expressed by stock prices, declined more after a corporation was prosecuted or reached a settlement for violations, as compared to corporations that disclosed earnings disappointments. Also, this study investigated the stock prices of violating corporations compared to the non-offending corporations from within the same business sector, as well as considered the percentage decline for repeat offenders for violation two compared to violation one. Opposite to hypothesis, results showed that stock prices for the violating companies were significantly greater 12 months after the violation compared to the other months and no significant differences in percent decline between the eight sectors on any of the five decline measures. There were also no differences between violating companies and their matched companies. Companies with a violation had significantly greater stock prices overall than those without a violation.
