Wind bands have been recording for over one hundred years. Through advancements in both technology and process, recordings have made a monumental impact on the wind band and its repertoire. These advancements have created clarity regarding the performance practice of pieces and helped to preserve the wind band repertoire. Many early works have gained masterwork status due, in large part, to the fact that recordings have preserved them. The increase in popularity of recording and, in particular, the wind band, warrants an investigation into the various aspects of the process. Additionally, gaining insight from wind band professionals who record will help to evaluate the contributions that recording has made to the education of performers and listeners, the preservation of repertoire and the artistic enhancement of the wind band. Each chapter explores aspects of the recording process and how those aspects have shaped the wind band, its repertoire and performance practice. Information from conductors, composers and engineers provide valuable insight pertaining to the educational, historical and artistic components of the recording process. The goal of all involved in the recording process should be the pursuit of technical perfection, which does not eclipse the ultimate musical goals of the project and the …

Abstract This dissertation investigates authentication techniques in some emerging areas. Specifically, authentication schemes have been proposed that are well-suited for embedded systems, and privacy-respecting pay Web sites. With embedded systems, a person could own several devices which are capable of communication and interaction, but these devices use embedded processors whose computational capabilities are limited as compared to desktop computers. Examples of this scenario include entertainment devices or appliances owned by a consumer, multiple control and sensor systems in an automobile or airplane, and environmental controls in a building. An efficient public key cryptosystem has been devised, which provides a complete solution to an embedded system, including protocols for authentication, authenticated key exchange, encryption, and revocation. The new construction is especially suitable for the devices with constrained computing capabilities and resources. Compared with other available authentication schemes, such as X.509, identity-based encryption, etc, the new construction provides unique features such as simplicity, efficiency, forward secrecy, and an efficient re-keying mechanism. In the application scenario for a pay Web site, users may be sensitive about their privacy, and do not wish their behaviors to be tracked by Web sites. Thus, an anonymous authentication scheme is desirable in this case. That is, a …

The Universalis Ecclesiae of 1508 authorized Spanish colonization of the Americas in return for the conversion of native populations to Christianity. From its inception therefore, the Mexican nation lived an alliance between Church and State. This alliance promoted the transfer of Castilian Catholicism to American shores. Catholic practices, specifically the ex-voto tradition, visualize this intermingling of religion and politics. The ex-voto is a devotional painting that expresses gratitude to a religious figure for his/her intervention in a moment of peril. It is commissioned by the devotee as a means of direct communication to the divine. This project analyzes 40 Mexican ex-votos for their reflection of political issues in Mexico. I assert that the Mexican ex-votos engage discussions of social politics. To support this argument, visualizations of socio-political discourses such as the Virgin of Guadalupe as a national religious symbol, police action and economic disparity were examined.

In order for America to retain its superior position in a global economy it is imperative that all students receive educational opportunities that will prepare them for the future. Currently, African-American economically disadvantaged students in the United States perform lower on standardized tests than their grade and age-level peers. Educators must find ways to improve the performance of students in this group in order to maximize future opportunities. Through a mixed-methodology approach, the current study finds three school factors that may positively impact the performance of African-American economically disadvantaged students: high expectations, student-teacher relationships and teacher effectiveness. Quantitative and qualitative analysis provides perspectives from principals primarily from a large urban school district on the impact of these factors on student performance.

Implicit in the call for educational reform in the teaching of social studies has been the suggestion that pursuing inquiry-based principles will lead to improvement in student achievement. The purpose of this study was to compare the effectiveness of two types of pedagogy: traditional and inquiry-based upon student achievement as measured by a standards-based, state administered examination. Second, this study examined the relationship between the treatment teachers' level of implementation and student achievement. A nonequivalent control group posttest and experimental design was used in this study. Subjects involved in this study include 84 secondary American history teachers and their respective students from a large urban public school district in Texas. The sample consisted of two groups, one taught by traditional/didactic instruction (n=48) and the other taught by inquiry-based pedagogy (n=36). Data for this study were collected using a classroom observation protocol based upon the level of use rubric developed by the concerns-based adoption model. An analysis of variance (ANOVA) (p<.05) was used to measure the effects of inquiry-based instruction and traditional pedagogy on student achievement. Student achievement results were measured by the Texas Assessment of Knowledge and Skills (TAKS) for American history, grades 8 and 11. The study found that …

Tree diameter data from 29 years of observations in six permanent plots was used to calculate the growth rate parameter of the FACET gap model for 39 species in the Imataca forests in Venezuela. The compound topographic index was used as a measure of differential soil water conditions and was calculated using geographic information systems. Growth rate values and topographic conditions typical of hill and valley were input to FACET to simulate dynamics at the species level and by ecological and functional groups. Species shade-tolerance led to expected successional patterns. Drought-tolerant/saturation-intolerant species grew in the hills whereas drought-intolerant/saturation-tolerant species occurred in the valleys. The results help to understand forest composition in the future and provide guidance to forest management practices.

In recent years, the accounting profession has faced increased scrutiny because of scandals involving management fraud (e.g., Enron, WorldCom). In response, Statement on Auditing Standards (SAS) #99 has expanded auditors' responsibility for detecting fraud, requiring auditors to gather significantly more information in their assessment of fraud. In addition, the Public Company Accounting Oversight Board (PCAOB) will focus on fraud detection through their inspections of registered accounting firms. In light of the increased emphasis on auditors' responsibility for detecting fraud, public accounting firms face the challenge of improving their fraud detection process, including their assessment of management fraud risk. Decision aids are one way for auditors to improve their assessment of management fraud risk. In fact, several studies from the decision aid literature suggest that aids are useful tools for a variety of tasks, including fraud risk assessment. At the same time, another stream of the decision aid reliance literature, which looks at people's willingness to rely on decision aids, suggests that individuals tend to be reluctant to accept the output given by an aid. Thus, the primary focus of this paper is on uncovering factors that would encourage one to voluntarily use and rely upon a decision aid. Toward that …

The impact of social influence from others on choices made by subjects and how this influence accumulates was studied by secondary analysis of reported experimental data. To explain this impact a link is proposed between social influence network theory (SINT) and status characteristics theory (SCT). The link formula transforms stay probabilities for different status relationships of subject with one disagreeing other agent into horizontal axis coordinate values while stay probabilities of subject given two disagreeing others are transformed into vertical-axis coordinate values corresponding to the horizontal axis values for further analyses. The results support the utility of the proposed link between the two theories.

Research has linked rape victim-blaming attitudes (VBAs) with gender role stereotyping, negative peer attitudes towards women, and acceptance of interpersonal violence. The current study analyzed longitudinal questionnaire data of college men (n=166) from White and Smith's (2001) study of college student victimization. Results indicate that VBAs can be conceptualized as either overt or covert, and that the covert VBA was more strongly correlated with alcohol use, sexualized peer attitudes, traditional gender stereotypes, need for sexual dominance, and perpetration of dating aggression. The covert VBA was also correlated with rape proclivity one year later, and partially mediated relationships between earlier variables and later rape proclivity. Additionally, endorsement of chivalry moderated the relationship between traditional gender stereotypes and the covert VBA, casting new perspective on the role of chivalry. Overall, results demonstrate the importance of targeting subtle expressions of VBAs in educational programs, and the need for longitudinal studies on rape attitude development.

The purpose of this research was to manipulate the component of confidence found in Keller's ARCS model to enhance the confidence and performance of undergraduate students enrolled in an online course at a Texas university using SAM 2003 software delivery. This study also tested whether the aforementioned confidence tactics had any unintentional effect on the remaining attention, relevance, and satisfaction subscales of the ARCS model as well as on learners' overall motivation for the class and the instructional materials. This study was conducted over a 5.5-week period with an initial sample of 81 total students. Two quantitative surveys were used to measure confidence and motivation: (a) the Course Interest Survey (CIS), and (b) the Instructional Materials Motivation Survey (IMMS). The results indicated that the treatment group showed statistically greater gains than the control group in terms of learner confidence on the CIS but not the IMMS. In terms of performance, the treatment group outperformed the control group on all of the individual posttest measures and on the overall aggregate mean performance score. The results showed no statistically significant difference on the attention subsection of the ARCS model. However, statistically significant differences were noted for the relevance and satisfaction subscales of …

This study compared strategy use and beliefs about language learning, and the relationship between beliefs and use reported by 428 monolingual Korean and 420 bilingual Korean-Chinese university students. This study also examined the influence of background variables (e.g., gender, self-rated English proficiency, and academic major) on learners' beliefs and strategy use. Data was collected using three questionnaires, the Strategy Inventory for Language Learning (SILL), the Beliefs about Language Learning Inventory (BALLI), and the Individual Background Questionnaire (IBQ). Data were analyzed using descriptive analyses, principal-component analyses, factor analyses, Pearson r correlation analyses, multivariate analysis of variance (MANOVA), and the Scheffé post-hoc test. Monolinguals reported using compensation strategies most, followed by cognitive, metacognitive, memory, social/practical practice, and affective strategies. Bilinguals preferred to use cognitive strategies most, followed by metacognitive and affective, compensation, memory, social, and independent practice strategies. Students from both groups reported low use of social and memory strategies. Despite a less favorable formal English education environment in the Korean-Chinese community and fewer English learning experiences, bilingual Korean-Chinese reported higher use of learning strategies, which indicates bilinguals' superior language learning abilities. Students from both groups had strong instrumental motivation for learning English. Bilinguals held stronger beliefs about the importance of formal …

The effects of two positive reinforcement procedures were evaluated to increase contact with, proximity to, and acceptance of new foods in a young child with autism. During baseline, two groups of six food items were presented. One group was intervened on. The first condition involved a changing criterion contingency and social attention as a consequence. The second involved a shaping contingency and access to videos as a consequence. The types of contact emitted, the amount of time spent contacting the food, and two affect topographies were measured. The second procedure resulted in increased duration and variety of contact, and increases of both affect topographies. Results are discussed in the context of food selectivity in autism, programming goals, and balancing intervention efficacy and restrictiveness.

In response to a growing teacher shortage, increasing numbers of secondary teachers are prepared through streamlined certification programs. For this reason, assessing candidates' content area knowledge gained from institutions of higher education across the United States is an important program admission factor as candidates must demonstrate content area knowledge by passing a Texas content area certification test (TExES). This study examines content knowledge for candidates enrolled in an online post­-baccalaureate program from September 1, 2002 through April 30, 2005. Academic transcript analysis and grades 8-­12 subject tests of the TExES were used as a proxy for subject matter knowledge for a sample of individuals seeking initial teacher certification in a post­-baccalaureate teacher certification at the University of North Texas. Descriptive data,linear regression, and logistic regression analyses were used to draw conclusions about the content area knowledge of the individuals in the sample. Scores on the TExES were used to determine the relationships between the content area knowledge of initial certification students and the number of content area courses completed, the grade point averages, and time elapsed between the completion of the last content area course and the student's initial attempt on the TExES. Results differed by the content area of …

The primary purpose of this study was to test the theory of experiential learning by measuring to what extent work experience predicts the work ethic characteristics of students in baccalaureate nursing programs at three regional universities in Texas, including Midwestern State University in Wichita Falls, Tarleton State University in Stephenville, and West Texas A&M University in Canyon. Work experience is the amount full-time or part-time on-the-job experience. Work ethic attributes are referred to as considerate, ambitious, dependable, and cooperative. Results generated in this study failed to reject the null hypotheses, which means that work experience, does not provide evidence of the ability to predict the development of work ethic characteristics in baccalaureate nursing students who participated in this research study. Knowledge generated in this study provided alternative directions for future research with respect to the relationship between work experiences and work ethic characteristics in nursing students. Such research may be useful to nursing educators and trainers in the design and delivery phases of the educational process for nurses.

Why is black partisan identification so one-sidedly Democratic forty years past the Civil Rights movement? A black/non-black political dichotomy manifests itself through one-sided African-American partisanship. Racial consciousness and Republican hostility is the basis of the black/non-black political dichotomy, which manifests through African-American partisanship. Racial consciousness forced blacks to take a unique and somewhat jaundiced approach to politics and Republican hostility to black inclusion in the political process in the 1960s followed by antagonism toward public policy contribute to overwhelming black Democratic partisanship. Results shown in this dissertation demonstrate that variables representing economic issues, socioeconomic status and religiosity fail to explain partisan identification to the extent that Hostility-Consciousness explains party identification.

Language can sometimes be an impediment in communication. Whether we are talking about people who speak different languages, students who are learning a new language, or people with language disorders, the understanding of linguistic representations in a given language requires a certain amount of knowledge that not everybody has. In this thesis, we propose "translation through pictures" as a means for conveying simple pieces of information across language barriers, and describe a system that can automatically generate pictorial representations for simple sentences. Comparative experiments conducted on visual and linguistic representations of information show that a considerable amount of understanding can be achieved through pictorial descriptions, with results within a comparable range of those obtained with current machine translation techniques. Moreover, a user study conducted around the pictorial translation system reveals that users found the system to generally produce correct word/image associations, and rate the system as interactive and intelligent.

This mixed design study surveyed members of the National Association of Student Personnel Administrators (NASPA) to determine the baseline for wellness among student affairs administrators and within the profession. In addition to describing the wellness levels of the administrators and comparing them to the wellness of the general population, the study explored how wellness is represented within the student affairs profession, as reflected in the literature and practice. Student affairs administrators' wellness was assessed utilizing the Five Factor Wel Wellness Inventory (Myers & Sweeney, 2004). Collectively, the administrators posted "well" scores on the six factors utilized in the study and scored higher than the norms reported for the 5F-Wel general population. However, there was a broad range of actual scores across individuals indicating that not everyone can be considered to be maintaining a well-balanced lifestyle. The administrators' wellness was not affected by their length of time in the student affairs profession but was negatively associated with the number of hours they worked per week. The administrators possessed a holistic view of wellness and could articulate the behaviors and conditions associated with achieving, and failing to achieve, balance. However, reported engagement in certain wellness behaviors (e.g., physical activity and healthy eating) …

This essay investigates the relationship between trance and various musical and poetic expressions that accompany trance when it is interpreted as sacred. In other words, the aim of this investigation is to interpret how experiences of the entrancing power of the sacred come to expression with the sounds of music and poetry. I articulate such an interpretation through the following four sections: I) a discussion of the basic phenomenological and hermeneutic problems of interpreting what other people experience as sacred phenomena, II) an account of the hermeneutic context within which modern Western discourse interprets trance as madness that perverts the rational limits of the self, III) an interpretation of the expressions of trance that appear in the poetry of William Blake, and IV) an interpretation of expressions of trance that appear in the music of Afro-Atlantic religions (including Vodu in West Africa, Santería in Cuba, and Candomblé in Brazil).

Positive psychology has become influential in research and practice. However, some have criticized positive psychologists who focus solely on the virtues of being positive. A tyrannical pressure to be positive may potentially exist in positive psychology, as well as mainstream United States culture. The following study explored perceptions of this theory using focus groups of individuals who differed in coping style, social desirability, and depression. Results suggest that individuals are affected by social pressures to be positive, and the expression of both positive and negative emotions is determined by social pressures, rules, context, and consequences. Although emotional expression, especially negativity, is contraindicated in several social contexts, there are also social, psychological, and physical benefits to all types of emotional expression.

The problem addressed is to ascertain how selected factors impacted the adjustment of undergraduate university students. Undergraduate university students (n=382) from the University of North Texas completed measures of basic student information, perceived level of family support and level of parental attachment, and perceived level of college student adjustment. Parental Attachment and Family Support were found to positively correlate to the level of adjustment to college. Analyses of these data reveal a statistically significant difference in student adjustment to college when comparing the participants by age, university classification, and living arrangement. Further analysis reveals that there is a statistically significant difference between gender, race, students' marital status, and parents' marital status when measuring the outcome of perceived family support. Perceived level of parental attachment differs significantly when comparing students by their race, marital status, and their parents' marital status.

Opto-electronic semiconductor technology continues to grow at an accelerated pace, as the industry seeks to perfect devices such as light emitting diodes for purposes of optical processing and communication. A strive for greater efficiency with shrinking device dimensions, continually pushes the technology from both a design and materials aspect. Nanosystems such a quantum dots, also face new material engineering challenges as they enter the realm of quantum mechanics, with each system and material having markedly different electronic properties. Traditionally, the semiconductor industry has focused on materials such Group II-VI and III-V compounds as the basis material for future opto-electronic needs. Unfortunately, these material systems can be expensive and have difficulties integrating into current Si-based technology. The industry is reluctant to leave silicon due in part to silicon's high quality oxide, and the enormous amount of research invested into silicon based circuit fabrication. Although recently materials such as GaN are starting to dominate the electro-optical industry since a Si-based substitute has not been found. The purpose of the dissertation was to examine several promising systems that could be easily integrated into current Si-based technology and also be produced using simple inexpensive fabrication techniques such ion implantation. The development of optically active …

The teacher professional development component of the will, skill, tool model of technology integration was tested for predictive validity in the cross-cultural context of data from Texas, USA, and data from Mexico City, Mexico. Structural equation modeling (SEM) analysis, path analysis, and multiple regression analysis, were statistical procedures employed. The analyses yielded positive results for the model's validity and reliability. The resulting model was found to be a reliable tool to evaluate technology integration among elementary and middle school teachers in Texas and in Mexico City. For the purposes of this study, the teacher professional development component of the will, skill, tool model of technology integration is referred to as the will, skill, tool model of technology integration (WiSTTI). This was one of the seven alternative models tested for goodness of fit across a total of 7 data samples. The structural equation modeling approach proved to be a good technique to find the best fit model in a cross-cultural environment. Latent variables and a set of parameters to judge the validity and reliability of each model were set for testing and retesting in an iterative process. Eventually a "new" modified version of the WiSSTI model was found to fit the …

Design of systems in the low-end nanometer domain has introduced new dimensions in power consumption and dissipation in CMOS devices. With continued and aggressive scaling, using low thickness SiO2 for the transistor gates, gate leakage due to gate oxide direct tunneling current has emerged as the major component of leakage in the CMOS circuits. Therefore, providing a solution to the issue of gate oxide leakage has become one of the key concerns in achieving low power and high performance CMOS VLSI circuits. In this thesis, a new approach is proposed involving dual dielectric of dual thicknesses (DKDT) for the reducing both ON and OFF state gate leakage. It is claimed that the simultaneous utilization of SiON and SiO2 each with multiple thicknesses is a better approach for gate leakage reduction than the conventional usage of a single gate dielectric (SiO2), possibly with multiple thicknesses. An algorithm is developed for DKDT assignment that minimizes the overall leakage for a circuit without compromising with the performance. Extensive experiments were carried out on ISCAS'85 benchmarks using 45nm technology which showed that the proposed approach can reduce the leakage, as much as 98% (in an average 89.5%), without degrading the performance.
