A Performance Guide for Pearls I and Pearls II by Roland Szentpali
This dissertation is a performance guide for the euphonium solos Pearls I and Pearls II, written by Roland Szentpali. This performance guide allows performers to better understand the jazz styles within each movement and provides them with a resource for performing these particular pieces as well as other jazz influenced pieces. This performance guide is specific to euphonium repertoire and written for euphonium performers and educators. This is also a resource for a solo work in the repertoire that is performed regularly as well as a new work that will soon be published. A brief history of the development of euphonium repertoire and the influence of jazz is provided. The performance guide analyzes each movement and provides insight to extended techniques, common performance problems, errata, and jazz styles that each movement is based on. The guide also provides several suggestions for interpretation and for performance preparation. Illustrations from the scores have been provided for each example.
Using Financial Rankings to Identify Characteristics of Libraries Serving Highly Profitable Private Law Firms
This purpose of this study was to develop evidence of a relationship between law libraries and private law firm profitability for law library administrators to use when making strategic decisions that influence the value of their libraries. The highest ranked administrator at each private law firm listed on the 2008 Am Law 200 was invited to complete an online benchmarking survey. The adjusted sample population totaled 179 firms. Fifty-one valid surveys were completed for a 28.5% response rate. Descriptive and statistical analyses were conducted using 26 independent variables (law library characteristics) and a single dependent variable, Revenue per Equity Partner, developed from data published for the Am Law 200. The most significant contributions of this study are: development of important law library financial and return on investment benchmarks; a listing of characteristics that have been empirically shown to impact law firm productivity; identification of optimum reporting structure for the law library administrator. Six characteristics positively impact Revenue per Equity Partner: to whom the library Administrator reports, number of library staff per library, number of Library staff per library, range in hourly bill rate for library staff time, practice areas most often supported. Two monetary measures were also established. The cost benefit of an Am Law library to its firm is $1.00 : $1.68. Each Am Law Library staff member is worth $295,000 in Revenue per Equity Partner to a firm. Law library practitioners can use the results to support evidenced-based strategic decision making in the administration of any private law firm library. Faculty and students in law librarianship programs will have a greater understanding of how to manage law libraries and collections to provide maximum value to their law firms. Benefits to library and information science research include validation of the research design and benchmarking as a theoretical framework for ...
Hepatotoxicity of Mercury to Fish
Tissue samples from spotted gar (Lepisosteus oculatus) and largemouth bass (Micropterus salmoides) were collected from Caddo Lake. Gar and bass livers were subjected to histological investigation and color analysis. Liver color (as abs at 400 nm) was significantly correlated with total mercury in the liver (r2 = 0.57, p = 0.02) and muscle (r2 = 0.58, p = 0.01) of gar. Evidence of liver damage as lipofuscin and discoloration was found in both species but only correlated with liver mercury concentration in spotted gar. Inorganic mercury was the predominant form in gar livers. In order to determine the role of mercury speciation in fish liver damage, a laboratory feeding study was employed. Zebrafish (Danio rerio) were fed either a control (0.12 ± 0.002 µg Hg.g-1 dry wt), inorganic mercury (5.03 ± 0.309 µg Hg.g-1 dry wt), or methylmercury (4.11 ± 0.146 µg Hg.g-1 dry wt) diet. After 78 days of feeding, total mercury was highest in the carcass of zebrafish fed methylmercury (12.49 ± 0.369 µg Hg.g-1 dry wt), intermediate in those fed inorganic mercury (1.09 ± 0.117 µg Hg.g-1 dry wt), and lowest in fish fed the control diet (0.48 ± 0.038 µg Hg.g-1 dry wt). Total mercury was highest in the viscera of methylmercury fed zebrafish (11.6 ± 1.86 µg Hg.g-1 dry wt), intermediate in those fed inorganic diets (4.3 ± 1.08 µg Hg.g-1 dry wt), and lowest in the control fish (below limit of detection). Total mercury was negatively associated with fish length and weight in methylmercury fed fish. Condition factor was not associated with total mercury and might not be the best measure of fitness for these fish. No liver pathologies were observed in zebrafish from any treatment.
Ultrafast Laser Sampling of a Plant Tissue and ion Conductivity Measurement for Investigation of Light Stress Generation Mechanisms
In this study we applied ultra-short laser pulses on a biological sample (Arabidopsis), in order to cut it precisely in a square pattern and subsequently use it for studying stress generation mechanisms. For this purpose, we utilized femtosecond laser pulses at 100 fs pulse width and 80 MHz repetition rate. We took two processing parameters into consideration such as laser power, laser exposure time which is related to the stage speed. Therefore, we were able to find the laser optimum conditions for ablation of biological tissues. The mutant and wildtype (control) obtained from laser cutting with a size of 500 µm × 500 µm were directly transferred (in-situ with laser cutting) into a microfabricated chamber containing ~500 nanoliters deionized water for measuring ion conductivity. The ion conductivity is a signature of cell-death mechanisms caused by various stresses. A light with intensity of 100 µmol was exposed to the samples for 2 hours and 20 minutes as a source of stress. A quantitative electrical analysis with high accuracy was assured by utilizing a microchamber, which enables a measurement in nanoliter volume. We measured the impedance which is reciprocal of conductivity using a lock-in amplifier and a precise current source at frequency of 130 Hz. Initially high impedance of mutant sample tended to drop within 2 hours and finally approached the constant value which signified that the cell death mechanism was complete. However, the wildtype sample demonstrated approximately constant impedance (conductivity) during the experiment.
Strategic Versus Sincere Behavior: The Impact of Issue Salience and Congress on the Supreme Court Docket
The theory proposed here is that the Supreme Court behaves in a strategic manner at the agenda-setting stage in order to vote sincerely on the merits. To test this, I measure the impact issue salience and ideological distance between Congress and the Supreme Court has on the agenda. The results indicate that whether the Supreme Court behaves either sincerely or strategically depends on the policy area. The strategic nature of the Supreme Court at the agenda-setting phase may be in large part why some research shows that the Court behaves sincerely when voting on the merits. By behaving strategically at the agenda-setting phase, the Court is free to vote sincerely in later parts of the judicial process.
The Piano as an Orchestra: The Accompanist and the Twentieth-Century Orchestral Reduction
The musical developments of the 20th century have expanded the role of the accompanist. As the compositional output of our time increases, and the opportunity to perform as soloist with an orchestra diminishes, piano reductions of an orchestral score are becoming the most frequent vehicle for concerto performances of twentieth and twenty-first century instrumental literature. While the current state of research provides solid support to many accompanists, it is in the area of instrumental accompanying, especially with regard to the challenges of playing a reduction of an orchestral score with an instrumental soloist, that the lack of discourse becomes strikingly evident. It is the goal of this study to provide the instrumental accompanist with concrete, practical approaches and considerations in order to perform an orchestral reduction in a manner consistent with the integrity of the score. Problems such as identifying the represented orchestral instruments, delineating importance of musical lines, and basic uses and misuses of pedal, articulation, and rubato are discussed. The pianist is led through ways of deciphering and negotiating specific passages, in order to guide the accompanist through the possible pitfalls and challenges unique to many orchestral reductions. By focusing on twentieth century reductions, providing examples of problems and discussing ways to solve them, the pianist will able to apply these to any reduction encountered, not just those specifically illustrated here. These basic principles of discerning common problems and appropriately reconciling them are then applied in a more advanced form to Robert Nelson's Concertino for Baritone Saxophone (1996). Through commentary from the composer, and a comparison of the orchestral score to the reduced piano score, the accompanist will explore detailed techniques of performing this work in a manner that upholds the original “orchestral” intent of the music.
Team performance: Using financial measures to evaluate the effect of support systems on team performance.
Organizations invest in team-based systems in order to generate innovative practices that will give them a competitive edge. High-performing teams require training and other support systems to gain the skills they need as well as to create and maintain an environment conducive to their success. The challenge for managers is to make resource allocation decisions among investment alternatives to maximize team effectiveness and still ensure a financial return for company investors. This study has three objectives. The first objective is to investigate whether there is a positive relationship among organizational environment, team potency (the team's collective belief it will succeed) and team performance. Results indicate that the presence of four organizational support systems influences team potency and performance. These support systems are the Design and Measurement, Rewards, Training and Communications Systems. In addition, results indicate that team potency is a mediating variable between the Design and Measurement and Communications Systems and team performance. These results suggest that companies are able to influence team performance by investing in environmental support systems. The second objective is to examine whether team members and managers view the organizational environment differently. Results indicate that managers view the Training and Communications Systems as more important, while teams perceive the Design and Measurement System and the Rewards System to be more important to their success. Since the systems that team managers view as important may influence their investment decisions, these differences may suggest a resource alignment issue. Third, a measure of team effectiveness based on financial measures is introduced. Published literature emphasizes attitudinal, behavioral and operational measures of performance. A financial measure offers a method of evaluating performance that is similar to methods used in capital budgeting and may be consistently applied across different types of teams with different purposes. The data collection process was performed by ...
Synthesis of Crown Ether/Ammonium Salt for Electron Transfer Study
The theoretical model of Beratan and Onuchic predicts a large attenuation of ET rates through hydrogen bonds; however, the effect of individual hydrogen bond on electron transfer reaction has not been systematically studied. The organic complexes in this study are a series of crown ether/ammonium salt, which incorporate a redox partner on each component of the complex. The dimethoxynaphthalene redox donor was attached to the crown ether and a series of ammonium salts was synthesized which bear substituted quinone and naphthoquinone acceptor. The complexes characterization and preliminary electron transfer rate measurement were completed with UV/Vis and steady-state emission spectroscopy.
Faculty Members' Readiness for E-learning in the College of Basic Education in Kuwait
E-learning exposes students and instructors to different learning models such as constructivism rather than the traditional learning. E-learning as a part of today's technology has proven that it is appropriate for most students' mentalities and is a mind tool which promotes different learning models, such as problem solving strategy, collaborative learning, and critical thinking. The Public Authority for Applied Education and Training (PAAET) in Kuwait consists of more than 10 academic colleges with a total number of 120 faculty members. The College of Basic Education (CBE) is one of them. The implementation of e-learning at the College of Basic Education requires that all the learning community members, instructors and students, understand that an e-learning course is like a learning community with the privilege of sharing knowledge, opinions, experiences related to class subject, and productive outcomes that are beneficial to this learning community. This study indentified the statistically significant differences in demographic characteristics of e-learning adopters and non-adopters among faculty members at CBE, examining faculty members' attitudes and skills toward e-learning readiness. The study will explore perceived barriers that face e-learning at CBE. Applying the Rogers diffusion of innovation theory, the influence of 4 factors was examined regarding faculty readiness for e-learning at CBE. Chi-square techniques, t-tests, and factor analysis were conducted to analyze the data and answer research questions. Statistically significant differences were identified among e-learning adopters and non-adopters regarding age difference and department discipline, both technical and non-technical.
The Works for Clarinet Commissioned by the Concours International d'Exécution Musicale de Genève: A Critical Survey and Performance Guide
Beginning in 1939, the Concours International d'Exécution Musicale de Genève (CIEM; Geneva International Music Competition) is unique among international music competitions in its multidisciplinary approach. To date, fifteen works have been commissioned for clarinet for the years in which the clarinet was involved. The most well-known of these works is the unaccompanied work by Heinrich Sutermeister, Capriccio for Solo Clarinet in A, written in 1946 for the 1947 competition. This work is a staple in the unaccompanied clarinet repertoire. However, the other fourteen works commissioned for the competition are little known and to date no document has been prepared that examines each of these works in the context of the competition and clarinet literature. While perhaps less notable, works were also commissioned for a sight reading portion of the competition for many of the years in which the clarinet was a discipline chosen for the competition, two of which were published. These works are examined as well. This survey provides a critical, analytical, historical, performance-related and biographical review of the published and unpublished works commissioned for the clarinet by CIEM. The composers, competitors and the significance of these works and winners in the clarinet literature and history are included. A chapter is dedicated to each piece which includes performance considerations, critical, analytical, and historical information as well as biographical information regarding the composer and the competitors where available.
Functional Neural Toxicity and Endocrine Responses in Mice Following Naphthalene Exposure
Polycyclic aromatic hydrocarbons (PAHs) are a well studied and diverse class of environmental toxicants. PAHs act via the aryl hydrocarbon receptor (AhR), and studies have suggested that PAHs may elicit neurological and estrogenic effects. Doses of PAHs between 50 to 150 ppm may elicit neurotoxicity in rodent models. The present study investigated the effects of naphthalene on in vivo steroidogenesis in Swiss Webster male mice, and in vitro neural function of Balb-C/ICR mice frontal cortex neurons. These data suggest that naphthalene may not elicit steroidogenic effects at concentrations ranging from 0.2 to 25 mg/kg/day, following a 7 day subcutaneous dosing regime. In addition, naphthalene may cause functional toxicity of frontal cortex neurons at concentrations of 32 to 160 ppm naphthalene.
Well-Being and Academic Success in Gifted College Students: Early-College Entrants and Honors College Students
As a society, we seek to have our young people, including the gifted, be healthy and happy, and go to good schools with good teachers. Framed by Sayler's theoretical model of giftedness and thriving, this study examined psychological constructs (i.e. general self-efficacy, theories of intelligence, hope, gratitude, religiosity, disposition, and resiliency) to determine their mediating effect on personal well-being and academic success in gifted college students. The 213 subjects for this study included gifted college students from two distinct programs at the University of North Texas. One hundred twenty-two participants were students from the Texas Academy of Mathematics and Science (TAMS). TAMS is an early-college entrance program allowing gifted students to enter college after their sophomore year of high school. Ninety-one participants attended the UNT Honors College. Honors College students are gifted students who enter college after high school graduation. Latent transition, latent class, general linear model repeated measures, and regression analyses were used in the examination of the data. Results of the study revealed that positive disposition and hope-agency were significantly related to the development of personal well-being for gifted students during their first year of college. The ability to identify pathways to goals and the self-theory of intelligence as a fixed trait were significantly related to academic success during the first year at college. Knowledge of psychological constructs that are facilitative of the positive personal well-being and academic achievement helps parents, teachers, administrators, and counselors prepare gifted students for success in college.
"The Wider View": Engaging a New Generation of Singers through African-American Art Song
Through studying the poetry and its context, the lives of the poets and composers, and the musical choices which emerged from these combined influences, students of the "Millennial" generation may experience a deeper connection to art song and its role in defining and reflecting national character. Not yet a part of the traditional canon of American art song, the songs of African-American composers are of particular value in this regard, offering teachers, students, and recitalists less frequently-performed repertoire to explore. Representing a broad spectrum of literary and cultural influences, these songs are just as diverse, multi-faceted, and full of variety as any other body of art song repertoire and richly contribute to the past and present life of the genre. Going beyond the music and the words can only reinforce the study of technique and enrich the studio experience, while at the same time providing a multicultural learning environment which more accurately reflects the America in which these same students will become the singers and voice teachers of tomorrow.
Mechanisms of rapid receptive field reorganization in rat spinal cord
Rapid receptive field (RF) reorganization of somatosensory neurons in the rat dorsal horn was examined using extracellular single unit recording. Subcutaneous injection of lidocaine into RFs of dorsal horn neurons results in expansion of their RFs within minutes. The expanded RFs appear adjacent to or/and proximal to original RFs. Out of 63 neurons tested, 36 (58%) show RF reorganization. The data suggest that dorsal horn of spinal cord is one of the initial sites for RF reorganization. The neural mechanisms of this effect are not well understood. We propose that changes in biophysical properties (membrane conductance, length constant) of the neurons resulting from lidocaine injection contribute to RF reorganization. Iontophoretic application of glutamate onto dorsal horn neurons that show lidocaine induced RF's expansion were used to test the model. Application of glutamate produced reduction of reorganized RFs in 9 of 20 (45%) tested cells. Application of NBQX produced no effect on either original or expanded RFs indicate that RF shrinkage effects of glutamate involve NMDA receptors. The results are consistent with the prediction of the proposed model. Subcutaneous injection of capsaicin into tactile RFs of low threshold mechanoreceptive dorsal horn neurons produced no effect on the RF sizes that are consistent with other studies. Following the injection, the original RFs were completely silenced (46%) or remained responsive (54%).
Reflections of Other/Reflections of Self
This Thesis collection contains a critical preface and five stories. The preface, “Reflejos y Reflexiones” (translated: Images and Thoughts), addresses the issues of writing the cultural or gendered Other; these issues include methodology, literary colonialism, a dialogue between works, and creating distance through defamiliarizing the self. “Perennials” is the story of Noemi Tellez, an immigrant to the U.S. who must choose between working and taking care of her family. In “Load Bearing” Luis, the eldest child, faces his family and friends on one of his last days before moving away to college. “La Monarca” deals with Lily's, the youngest daughter, struggle to mediate a place between her friends and her family. In “Reflections in the River,” Arabela, the second youngest, faces the ghost of an unwanted pregnancy and La Llorona. “La Cocina de Su Madre” is the story of Magda, the oldest daughter, and her own teenage girl, Natalia, as they attempt to find themselves in a new town after moving a thousand miles from home.
Leadership Frames of Female Presidents of American Research Universities
This study used case studies to examine the leadership frames of female presidents of four-year, public and private, coeducational research institutions both from the Intensive and Extensive Carnegie classifications within the United States. The population (N=30) surveyed was sent the Leadership Orientation Questionnaire (Self) developed from the previous research conducted by Lee Bolman and Terrance Deal. The Bolman and Deal leadership frame theory condensed existing organizational theories into a four-frame perspective consisting of a structural, human resource, political, and symbolic frame. Bolman and Deal theorized that the ability to use more than one frame is considered to be critical to the success of leaders and intensify that leader's capacity for making decisions and taking effective actions. The Leadership Orientation Questionnaire (Self) contains five sections that include rating scales for personal demographics, the four frames, eight leadership dimensions, and management and leadership effectiveness. The research questions sought to identify the demographic characteristics and academic histories of the survey participants and the associations between these variables, the leadership frames represented among the survey participants, and how many, and which, of the four frames the survey participants use collectively. This study allowed its participants to examine their perceptions of their own leadership frames in order to analyze the frame that dominates the way certain universities communicate. Thirteen of the thirty presidents (43%) completed and returned the survey. Survey participants who had 20 or more years of experience were more likely to exhibit the human resource or symbolic frame as their dominant style; presidents whose years of experience numbered less than 20 years exhibited a mulitframe perspective in their decision-making process. Overall, this research found that the survey participants exhibited most often the human resource frame, followed by the symbolic, structural, and political frames.

To Determine Whether or Not the Colleges of Texas are Preparing their Students of Industrial Arts to Teach Effectively in the High Schools of Texas
This is a study to determine whether the colleges of Texas are preparing their students of industrial arts to teach effectively in the high schools of Texas. The objectives of this study are to draw conclusions as to whether or not the colleges of Texas are preparing their students of industrial arts to teach effectively in the modern high schools; to show the training of industrial arts teachers; and to determine to what extent industrial arts are offered in the high schools of Texas.
Ability Estimation Under Different Item Parameterization and Scoring Models
A Monte Carlo simulation study investigated the effect of scoring format, item parameterization, threshold configuration, and prior ability distribution on the accuracy of ability estimation given various IRT models. Item response data on 30 items from 1,000 examinees was simulated using known item parameters and ability estimates. The item response data sets were submitted to seven dichotomous or polytomous IRT models with different item parameterization to estimate examinee ability. The accuracy of the ability estimation for a given IRT model was assessed by the recovery rate and the root mean square errors. The results indicated that polytomous models produced more accurate ability estimates than the dichotomous models, under all combinations of research conditions, as indicated by higher recovery rates and lower root mean square errors. For the item parameterization models, the one-parameter model out-performed the two-parameter and three-parameter models under all research conditions. Among the polytomous models, the partial credit model had more accurate ability estimation than the other three polytomous models. The nominal categories model performed better than the general partial credit model and the multiple-choice model with the multiple-choice model the least accurate. The results further indicated that certain prior ability distributions had an effect on the accuracy of ability estimation; however, no clear order of accuracy among the four prior distribution groups was identified due to an interaction between prior ability distribution and threshold configuration. The recovery rate was lower when the test items had categories with unequal threshold distances, were close at one end of the ability/difficulty continuum, and were administered to a sample of examinees whose population ability distribution was skewed to the same end of the ability continuum.
The Relationship Among Gender, Gender Role Attitudes, and the Anticipated Commitment to Career, Marriage, Family, and Housework
The relationships between gender, gender role attitudes, and participants' anticipation of future life roles (career, marriage, family, and homecare) were examined. Participants consisted of 297 single college students between the ages of 17-29 years (M = 20). Females reported significantly (p< .01) more egalitarian gender role attitudes than males. Significant results were found for the relationship between gender and anticipated life roles (p< .01) as well as between gender role attitudes and anticipated life roles (career role value, r = .14 and marital role value, r = - .18). The study findings suggest a possible gender conflict for females with more egalitarian gender role attitudes and behavior intentions and their male counterparts.

The Relationship of the Turnover of Teachers and College Training
A study to determine whether there is any relationship between teacher training and college training, between turnover of teachers and departmental training, and between grade point average, honor society students, and turnover of teachers.
Managerial self-awareness and its impact on leadership in high-performing managers.
Managerial self-awareness is thought to impact leadership. A multi-rater feedback instrument was used to gather performance data on 70 managers in a large multi-national airline in regards to five leadership dimensions: making sound decisions, driving for results, effective communication, self-management, and innovation. Difference scores between self and direct reports were calculated and used as the operational definition of managerial self-awareness. T-tests were run to examine the difference between high performers and average performers. No significant differences were found. Additionally, correlational measures between the five leadership competencies and the managerial self-awareness measure indicated statistically weak relationships.
Filial Therapy with Immigrant Korean Parents in the United States
This study was designed to determine the effectiveness of filial therapy training in: (a) increasing immigrant Korean parents' empathic behavior with their children; (b) increasing immigrant Korean parents' acceptance level toward their children; and (c) reducing immigrant Korean parents' stress related to parenting.The experimental group, consisting of 17 immigrant Korean parents in the United States, received 10 weekly 2-hour filial therapy training sessions and participated in weekly 30-minute play sessions with one of their children. The control group, consisting of 15 immigrant Korean parents in the United States, received no treatment during the ten weeks. All the parents were videotaped playing with their child before and after the training as a means of measuring change in empathic behavior. The two written self-report instruments completed for pretesting and posttesting purposes were the Porter Parental Acceptance Scale and the Parenting Stress Index. Analyses of covariance revealed that the immigrant Korean parents in the experimental group had significant changes in 10 of 12 hypotheses, including (a) a significant increase in their level of empathic interactions with their children; (b) a significant increase in their attitude of acceptance toward their children; and (c) a significant reduction in their level of stress related to parenting. This study supports the use of filial therapy for promoting the parent-child relationship in immigrant Korean families in the United States. Filial therapy helps immigrant Korean parents to be therapeutic agents for their children. It helps them regain their own power as parents and restore positive relationships with their children.
Comparing Five Empirical Biodata Scoring Methods for Personnel Selection
A biodata based personnel selection measure was created to improve the retention rate of Catalog Telemarketing Representatives at a major U.S. retail company. Five separate empirical biodata scoring methods were compared to examine their usefulness in predicting retention and reducing adverse impact. The Mean Standardized Criterion Method, the Option Criterion Correlation Method, Horizontal Percentage Method, Vertical Percentage Method, and Weighted Application Blank Method using England's (1971) Assigned Weights were employed. The study showed that when using generalizable biodata items, all methods, except the Weighted Application Blank Method, were similar in their ability to discriminate between low and high retention employees and produced similar low adverse impact effects. The Weighted Application Blank Method did not discriminate between the low and high retention employees.
Working Whiteness: Performing And Transgressing Cultural Identity Through Work
Early in Richard Wright's Native Son, we see Bigger and his friend Gus &#8220;playing white.&#8221; Taking on the role of &#8220;J. P. Morgan,&#8221; the two young black men give orders and act powerful, thus performing their perceived role of whiteness. This scene is more than an ironic comment on the characters' distance from the lifestyle of the J. P. Morgans of the world; their acts of whiteness are a representation of how whiteness is constructed. Such an analysis is similar to my own focus in this dissertation. I argue that whiteness is a culturally constructed identity and that work serves as a performative space for defining and transgressing whiteness. To this end, I examine work and its influence on the performance of middle class and working class whiteness, as well as how those outside the definitions of whiteness attempt to &#8220;play white,&#8221; as Bigger does. Work enables me to explore the codes of whiteness and how they are performed, understood, and transgressed by providing a locus of cultural performance. Furthermore, by looking at novels written in the early twentieth century, I am able to analyze characters at a historical moment in which work was of great import. With the labor movement at its peak, these novels, particularly those which specifically address socialism, participate in an understanding of work as a performative act more than a means to end. Within the context of this history and using the language of whiteness studies, I look at how gendered whiteness is transgressed and reinforced through the inverted job-roles of the Knapps in Dorothy Canfield's The Home-Maker, how work can cause those who possess the physical attributes of whiteness to transgress this cultural identity, as the Joads in The Grapes of Wrath demonstrate, and how the ascribed identities as non-white for Sara in The ...
Developmental Stressors and Associated Coping Skills in the Development of Disordered Eating in College Females
There is a lack of clarity in the current literature in how potential etiological factors interact and result in disordered eating. The purpose of this study was to examine an expanded model of Personality, Social Support, Appraisal/Coping Processes, Abuse History, Internalization of Sociocultural Standards, Psychological Disturbances, and Body Disparagement in the development of disordered eating. The current model was evaluated using 276 women in their transition to college, a time period highly associated with symptoms believed to increase a woman's risk for the development of disordered eating including perceived difficulty coping, weight gain, and negative affect. Structural equation modeling was used to allow simultaneous examination of the causal relationships between the factors. Structural analyses confirmed that college women with previous stressful experiences appraised the adjustment to college as more stressful and reported feeling less able to cope with the transition. Those women who identified the transition as overwhelming were also aware of increased negative mood and psychological states since beginning the school semester. Further, women with previous traumatic sexual experiences appeared to be at additional risk for increased negative affective symptoms. The resulting model confirmed that those women who experience negative mood states and those that endorse strong internalization of cultural values regarding attractiveness encountered increased dissatisfaction and disapproval of their bodies. Finally, women with higher levels of body concern engaged in more eating behaviors associated with disordered eating. The roles of personality functioning and perceived social support could not be identified in the developmental model. The predictive links between constructs in the resulting model provide meaningful information regarding the transition to college and associated risks for development of disordered eating. Validation of the model in an independent sample would provide confirmation of these relationships and longitudinal research examining females' attitudes across crucial developmental periods might provide important information regarding ...
Water Quality Aspects of an Intermittent Stream and Backwaters in an Urban North Texas Watershed
Pecan Creek flows southeast through the City of Denton, Texas. Characterized as an urban watershed, the basin covers approximately 63.5 km2. Pecan Creek is an intermittent stream that receives nonpoint runoff from urban landuses, and the City of Denton's wastewater treatment plant, Pecan Creek Water Reclamation Plant, discharges effluent to the stream. Downstream from the City of Denton and the wastewater treatment plant, Pecan Creek flows about 6,000 m through agricultural, pasture, and forested landscapes into Copas Cove of Lake Lewisville, creating backwater conditions. Pecan Creek water quality and chemistry were monitored from August 1997 to October 2001. Water quality was influenced by seasonal, spatial, climatic, and diurnal dynamics. Wastewater effluent discharged from the Pecan Creek Water Reclamation Plant had the greatest influence on water quality of the stream and backwaters. Water quality monitoring of Pecan Creek demonstrated that dissolved oxygen standards for the protection of aquatic life were being achieved. Water quality modeling of Pecan Creek was completed to assess future increases in effluent flow from the Pecan Creek Water Reclamation Plant. Water quality modeling indicated that dissolved oxygen standards would not be achieved at the future effluent flow of 21 MGD and at NPDES permitted loadings. Model results with application of a safety factor indicated that the maximum allowable concentrations for a 21 MGD discharge would be 2.3 mg/L of ammonia and 7.0 mg/L of biochemical oxygen demand at summer conditions. Drought conditions that occurred from 1998 to 2001 reduced water levels in Lake Lewisville and impacted dissolved oxygen water quality in Pecan Creek. Water quality observations made during the period of drought allowed for the development of a model to estimate the zone of the dissolved oxygen sag in Pecan Creek based on reservoir elevation. Finally, monitoring results were analyzed with nonparametric statistical procedures to detect water ...
Civil Asset Forfeiture in the Fight Against Drugs (Policy Analysis)
Even if the main criminals of an organization are incarcerated, they will be replaced by others who would continue illegal activities, unless their financial assets are removed. Thus, civil forfeiture intends to dismantle the economic infrastructure of drug trafficking networks. Civil forfeiture considers the property as guilty, rather than the owner, and it may exist even if there is not a criminal action. Therefore, it is claimed that police agencies have chosen easy targets, such as wealthy drug users rather than major drug traffickers. Consequently, it has been particularly challenged on the basis of the Excessive Fines, Double Jeopardy, and Due Process Clauses. The use of criminal forfeiture instead of civil forfeiture and the elimination of the equitable sharing provision are considered to be the primary solutions.
Use of GIS and Remote Sensing Technologies to Study Habitat Requirements of Ocelots, Leopardus pardalis, in south Texas
The goals of this study were to use Geographic Information Systems (GIS) and remote sensing technologies to gain a better understanding of habitat requirements of a population of ocelots in south Texas, and then apply this knowledge to form a predictive model to locate areas of suitable habitat in Willacy and Cameron counties, Texas. Satellite imagery from August 1991 and August 2000 were classified into four land cover types: closed canopy, open canopy, water, and urban/barren. These classified images were converted into digital thematic maps for use in resource utilization studies and modeling. Location estimates (762 from 1991 and 406 from 2000) were entered into a GIS in order to extract information about home range and resource selection. Each animal's home range was calculated using both Minimum Convex Polygon (MCP) and Kernel home range estimators (95% and 50%). Habitat parameters of interest were: soil, land cover, human density, road density, and distance to closest road, city and water body. Ocelots were found to prefer closed canopy and avoid open canopy land cover types. Ocelots preferred soils known to support thorn scrub, an indication of the importance of this habitat. Landscape metrics associated with habitat used by ocelots were determined through the use of Patch Analyst, an extension for ArcView 3.2. Contrary to expectations, ocelots utilized areas with greater fragmentation than random areas available for use. However, this use of highly fragmented areas was an indication of the degree of fragmentation of suitable habitat in the area. Further investigation of patch size selection indicated that ocelots used large sized patches disproportionately to availability, indicating a preference for larger patches. A model was created using the resource selection and habitat preference GIS database from 1991. This model was used to identify areas of “optimal”, ”sub-optimal”, and “unsuitable” habitat for ocelots in 2000. ...
Wisdom and Law: Political Thought in Shakespeare's Comedies
In this study of A Midsummer Night's Dream, The Merchant of Venice, and Measure for Measure I argue that the surface plots of these comedies point us to a philosophic understanding seldom discussed in either contemporary public discourse or in Shakespearean scholarship. The comedies usually involve questions arising from the conflict between the enforcement of law (whether just or not) and the private longings (whether noble or base) of citizens whose yearnings for happiness tend to be sub- or even supra-political. No regime, it appears, is able to respond to the whole variety of circumstances that it may be called upon to judge. Even the best written laws meet with occasional exceptions and these ulterior instances must be judged by something other than a legal code. When these extra-legal instances do arise, political communities become aware of their reliance on a kind of political judgment that is usually unnoticed in the day-to-day affairs of public life. Further, it is evident that the characters who are able to exercise this political judgment, are the very characters whose presence averts a potentially tragic situation and makes a comedy possible. By presenting examples of how moral and political problems are dealt with by the prudent use of wisdom, Shakespeare is pointing the reader to a standard of judgment that transcends any particular (or actual) political arrangement. Once we see the importance of the prudent use of such a standard, we are in a position to judge what this philosophic wisdom consists of and where it is to be acquired. It is just such an education with which Shakespeare intends to aid his readers.
Political Misuse of Domestic Intelligence: A Case Study on the FBI
Domestic intelligence is very important in preventing disorder while ensuring unity and security during a time of national crisis. However, if uncontrolled, domestic intelligence can be subject to political misuse, which causes serious damage both to individuals and to democratic institutions. There are various theoretical explanations for political misuse of domestic intelligence. The political use of domestic intelligence is best explained by the sociological theory of unfulfilled needs. On the other hand, political counterintelligence can be best explained by Threat Theory. In order for a domestic intelligence organization to be effective, its organizational discretion must be limited by establishing clear legislation that is not secret, on the focus, limits, and techniques of domestic intelligence. This system must be supported by a multi-level control mechanism.
Influence of design and coatings on the mechanical reliability of semiconductor wafers.
We investigate some of the mechanical design factors of wafers and the effect on strength. Thin, solid, pre-stressed films are proposed as a means to improve the bulk mechanical properties of a wafer. Three-point bending was used to evaluate the laser scribe density and chemical processing effect on wafer strength. Drop and strike tests were employed to investigate the edge bevel profile effect on the mechanical properties of the wafer. To characterize the effect of thin films on strength, one-micron ceramic films were deposited on wafers using PECVD. Coated samples were prepared by cleaving and were tested using four-point bending. Film adhesion was characterized by notched four-point bending. RBS and FTIR were used to obtain film chemistry, and nanoindentation was used to investigate thin film mechanical properties. A stress measurement gauge characterized residual film stress. Mechanical properties of the wafers correlated to the residual stress in the film.
The Effects Of The Allocation Of Attention Congruent With Lateralized Cognitive Tasks On EEG Coherence Measurements
The single task condition of the Urbanczyk and Kennelly (1991) study was conducted while recording a continuous electroencephalographic (EEG) record. Attention was allocated by instructed lateral head orienting and eye gaze either congruently or incongruently with lateralized cognitive tasks. Thirty university subjects retained a digit span or a spatial location span for a 20 second retention interval. EEG data were extracted from the 20 second retention intervals and interhemispheric coherence was calculated for homologous sites in the temporal, parietal and occipital regions of the brain. There was a main effect for group, with congruent orienting producing greater coherence values than incongruent orienting. This effect of attention on alpha coherence values was found in the low alpha (8-10 Hz) frequency band. This provides evidence that the lower alpha frequency band is reflective of manipulations of attention. The higher coherence measures for the congruent orienting group indicates that homologous regions of the two hemispheres are more coupled into a single system when lateralized attention activates the same hemisphere performing the cognitive task. In the higher alpha frequency band (11-13 Hz) group, sex, site and task interacted. This provides evidence that the higher alpha band is more affected by cognitive processing of the specific task undertaken. An interhemispheric brain system, affected by the lateral orientation of attention, may underlie psychometric intelligence's general &#8220;g&#8221; ability (Spearman, 1927.)

The Solo Compositions for Trumpet of Fisher Aubrey Tull: An Analysis of Structural, Technical, and Stylistic Elements for Performance Preparation, with Three Recitals of Selected Works by Bozza, Fasch, Haydn, Tomasi, and Others
The compositions of Fisher Aubrey Tull are widely performed and many have become standard repertoire. Tull's compositions encompass a multiplicity of performance media including works for orchestra, chorus, symphonic band, jazz band, brass choir, and solo and chamber works. Tull's compositional output for the trumpet is prolific and is acknowledged to be music of high quality. An examination of Trumpet and Brass Programs, compiled and published annually by the International Trumpet Guild, shows Tull's solo and ensemble works for trumpet to be frequently performed. Furthermore, his compositions for trumpet have been performed and recorded by internationally acclaimed artists including Vincent DiMartino, Terry Everson, Håkan Hardenberger, Anthony Plog, Carl "Doc" Severinsen and Allen Vizzutti.This study investigates Fisher Tull's eight solo works for trumpet, which include: Vignette for Trumpet and Piano (1954); Concerto No. 1 for Trumpet and Orchestra (1964); Concerto No. 2 for Trumpet and Band (1974); Three Bagatelles for Trumpet and Piano (1975); Eight Profiles for Solo Trumpet (1978); Rhapsody for Trumpet and Band (1980); Sonata for Trumpet and Piano (1986); and Chromutations for Solo Trumpet (1988). Histories of each composition are chronicled. An analysis of formal organization and significant style features examines musical structure, harmonic language, rhythmic character, instrumentation, and orchestration. A discussion of technical concerns specific to the trumpet that addresses range, tessitura, articulation, flexibility, endurance and the use of extended techniques is included. Performance suggestions, pertaining to technical and artistic issues, offer the reader specific recommendations as an aid in performance preparation. Finally, the significance of Fisher Tull's works for trumpet and his impact on the trumpet literature is assessed. Evidence suggests that his prolific compositional output, diversity of forms, and musical quality rank him as one of the most significant composers for the trumpet in the twentieth century.
The Federal Constitution and Race-Based Admissions Policies in Public Charter Schools
The primary questions addressed in this dissertation are whether race-based admissions policies in charter schools are constitutionally permissible, and if not, how could an admissions policy be designed so that it would promote school diversity without violating the law? These questions are important because there are significant numbers of philosophers and scholars who hypothesize that student body diversity not only enhances educational outcomes but also is a necessary component of civic education in a liberal democracy. The researcher takes no particular stance on the benefits of educational diversity, focusing instead on the constitutional questions raised by the use of race-sensitive policies in the interest of diversity. The primary methodology used throughout is legal research, though the literature review includes references to political philosophers and social scientists as well as primary legal sources. Chapter I outlines the most frequent arguments made in favor of school diversity and suggests that the judicial philosophy expressed by the Supreme Court over the last twenty-five years has moved away from the philosophy expressed in Brown v. Board. In Chapter II, Supreme Court precedent on affirmative action policies is analyzed, focusing mainly on the decision of the divided Court in University of California Board of Regents v. Bakke. Chapter III provides a detailed analysis of how six different Federal Circuit Courts interpreted Bakke, highlighting numerous recurring judicial themes and concerns. In Chapter IV, existing charter school laws are examined state by state. Chapter V suggests several policy options for those interested in promoting a diverse charter school student body.
Neckbones and Sauerfowches: From Fractured Childhood in the Ghetto to Constantly Changing Womanhood in the World
A collection of five memoiristic essays arranged about themes of family, womanhood and the African-American community with a preface. Among the experiences the memoirs recount are childhood abandonment; verbal and emotional child abuse; mental illness; poverty; and social and personal change. Essays explore the lasting impact of abandonment by a father on a girl as she grows into a woman; the devastation of family turmoil and untreated mental illness; generational identity in the African-American community. One essay describes the transition from the identity-forming profession of journalism to academia. The last essay is about complicated and conflicting emotions toward patriotism and flag-waving on the part of a black woman who has lived through riots, little known police shootings of students on black campuses, and many other incidents that have divided Americans.
"Ch'io t'abbandono" by Felix Mendelssohn Bartholdy: A Dramatic Image of the Education and Aptitudes of the Composer
The unpublished concert aria, "Ch'io t'abbandono," by Felix Mendelssohn Bartholdy (1825), is representative of the adolescent composer's developing musical aesthetic. In this study, Mendelssohn's education, work ethic, and perfectionism are revealed, paradoxically, as both the catalysts for the piece's composition and also the reasons it was not published during Mendelssohn's lifetime. An exploration of the text, form, thematic usage, and performance demands of the aria yields specific examples of his uniquely balanced romantic-classicist style. A consideration of possible original performers of the piece, Franz Hauser and Eduard Devrient, leads to further discussion about the nature of the work as both a reflection of Mendelssohn's romantic self-expression and his appreciation for the Baroque melismatic style. The significance of the aria, both stylistic and biographical, is further delineated by a presentation of possible motivations for its composition. The musical setting of the text, as well as the text itself, indicates both Mendelssohn's awareness of himself as a maturing adolescent composer and his desire to be a composer of operatic works, a desire that was never fully realized.
Performing the Trumpet works of Donald Erb; A Guide to Preparation, Interpretation and Practices: A Lecture Recital, Together with Three Recitals of Selected Works by Purcell, Hindemith, Holmes, Friedman, Koetsier and Others
This study is a guide to the performer on practices associated with the trumpet music of Donald Erb. It examines the following solo and duo compositions for trumpet: the as yet unpublished Sonatina for Trumpet and Piano (1954); Four Duets for Trumpets (1960); Diversion for Two for trumpet & percussion (1966); Concerto for Trumpet and Orchestra (1980); Remembrances for two trumpets (1994); and Dance, You Monster, To My Soft Song for solo trumpet (1998). A history of each composition and information concerning the performers who premiered them are documented. An examination of particular harmonic, melodic and rhythmic elements found frequently in these pieces follow. The pieces are further assessed for difficulty through an investigation of extended technical demands, range, endurance and articulation. Additional discussion focuses on the use of mutes, tempos and dynamics as well as suggestions for the preparation and performance of these works. The dissertation concludes with a review of Donald Erb's legacy as a composer and teacher. A comprehensive discography and complete list of Mr. Erb's compositions are included in appendices.
Understanding Ancient Math Through Kepler: A Few Geometric Ideas from The Harmony of the World
Euclid's geometry is well-known for its theorems concerning triangles and circles. Less popular are the contents of the tenth book, in which geometry is a means to study quantity in general. Commensurability and rational quantities are first principles, and from them are derived at least eight species of irrationals. A recently republished work by Johannes Kepler contains examples using polygons to illustrate these species. In addition, figures having these quantities in their construction form solid shapes (polyhedra) having origins though Platonic philosophy and Archimedean works. Kepler gives two additional polyhedra, and a simple means for constructing the “divine” proportion is given.
Supply chain relationships in apparel retail product development.
The purpose of this study was to investigate supply chain relationships within the apparel retail product development process under a single site case study setting. Relationship determinants (i.e. drivers, facilitators and barriers) that facilitated or impeded the degree of collaborative efforts between the retailer and the supply chain members were identified. As the retailer integrated its product development process with its suppliers, a triangular relationship was formed between the retailer, the overseas manufacturers, and the designated suppliers. The study found that the retailer sought operational efficiency in its business relationships with supply chain members, but continued to seek long-term commitment in these relationships to establish a virtual vertical company.
Mentoring the first-year superintendent in Texas public schools.
This study determined what mentoring experiences first-year superintendents have had and what they need from a mentoring relationship. Structured interviews and field notes were used in this qualitative study focused on Texas first-year superintendents' perceived needs from mentors. Three patterns of mentoring relationships were found: 1) no mentor in the first year, 2) mentor-protégé relationship - those who developed mentoring relationships early in a career with a more senior person in the same school system, and 3) mentoring relationships of convenience - young relationships which developed outside the same system. Skills and knowledge areas novice superintendents identified as critical for mentor assistance were school finance, development of effective relationships with groups that have expectations of the superintendent while also improving student achievement, and working within the politics of the position. Mentor characteristics novice superintendents considered necessary for a positive effect on job success include: trustworthiness, confidentiality, empathy, encouraging, active listening, and integrity. An attitude in which the mentor problem solved with the protégé, and did not give an immediate solution was displayed. Mentors actively and frequently initiated contact. Ideas were freely exchanged, giving the protégé undivided attention while not making the protégé feel inferior. The effects that previous mentoring experiences had on novice superintendents influenced whether they chose to mentor another person. Most reported seeking or engaged in a new mentoring relationship. Differences in areas where help was needed among first-year superintendents associated with district size were reported. Assistance in finance was needed regardless of district size, gender, or ethnicity. Superintendents in small districts reported needing assistance in specific skill and knowledge areas. Those in larger districts reported mentor assistance in problem-solving processes to accomplish a task. Differences in needs of first-year superintendents based on gender or ethnicity were identified but generalizations could not be made due to small numbers. ...
Effects of Sublethal Copper Exposure on Escape Behavior and Growth of Rana pipiens Tadpoles
This research is designed to test how sublethal exposure to copper affects tadpole predator-escape behavior and how quickly tadpoles recover. After exposure, tadpoles were separated. Escape behavior was recorded for two-thirds of exposed tadpoles while one-third of the exposed population was measured weekly to determine growth and recovery. Control tadpoles were consumed within 15 minutes whereas those exposed to higher concentrations were consumed at a slower rate, which does not support the hypotheses. Although the rate of predation was lower, tadpoles exposed to higher Cu concentrations were on average, 1.47 cm in total body length. Those exposed to 0.93 mg/L averaged 0.86 cm. After being placed into clean water, treatment tadpoles recovered after 20 days.
Pilgrim Carnival
This thesis explores an experimental music approach to writing autobiography. As a composition, Pilgrim Carnival took place as a travelling series of events. The central event was a sound installation for a blindfolded audience. This essay is a description of that series of events as well as a discussion of similar precedents in interdisciplinary art. Beginning with Luigi Russolo and Marcel Duchamp, aspects of autobiography are examined in both noise music and the concept of the ready-made artwork. Body Art of the 1970s, particularly the work of Marina Abramovic, is also tied into the idea of the ready-made artwork as an explicitly autobiographical example. The hybrid form of Pilgrim Carnival and the concept of ready-made autobiographical music create ongoing potential for new work.
Transnational Organized Crime and the Drug Business
This study analyzes the activities of the organized crime groups involved in the drug business, as well as examining national and international efforts to control these groups. Specifically, this study addresses the following questions: How is organized crime connected to the international drug business?; What are the major transnational organized crime groups involved in the international drug business?; What is the nature of the drug problem as it relates to organized crime internationally?; What international cooperative law enforcement efforts currently exist to deal with organized crime and the drug business? Findings indicate that efforts to create an effective international law enforcement network are needed to meet the challenges of drug trafficking and globalized crime. To date, such efforts have largely been unsuccessful.
The Nineteenth Century Oboe Concertino: An Overview of its Structure with Two Performance Guides
Music written for oboe and orchestra in the nineteenth century falls into three categories: Classical Concerto, Opera Fantasy, and Concertino. The classical, or standard, three movement, sonata-ritornello format was only sparingly used. Instead, composers chose more the experimental forms of the Opera Fantasy and Concertino. The Opera Fantasy was used as a way for oboe players to play popular opera arias of the time, while showcasing their virtuosity and expression. It is in the Concertino where composers expanded the oboe repertoire to its highest form in the nineteenth century, experimenting with structure, and using the oboe to the height of its expressive powers. In addition to discussion on the Concertino in general, performance guides have been provided for two concertinos, Concertino for Oboe and Winds, by Carl Maria von Weber and Concertino for Oboe and Orchestra, Op. 18, by August Klughardt. Information is provided regarding composer biography, compositional/historical perspective, technical and stylistic considerations, and structure. By examining the two very different pieces, one from the beginning of the nineteenth century and one from the end, the evolution of the Concertino can be seen, as well as gaining an understanding of the wide variety of repertoire written for the oboe in the nineteenth century.
