The purpose of this study was to examine a school district's responses to charter schools operating within its boundaries. The selected district was the only one in the state with two large academically competitive charter schools for at least two years. Four questions guided the research: In terms of instruction, finance, communication, and leadership, how has the traditional district been impacted due to charter school existence? The exploratory research was timely since charter schools are proliferating as tax-supported public choice schools. While many have speculated about free-market effects of charter school competition on systemic educational reform, the debate has been chiefly along ideological lines; therefore, little empirical research addresses this issue. Quantitative and qualitative methodologies were used to present a comprehensive case study. Twenty-six school officials and teachers were interviewed; 159 teachers and 1576 parents were surveyed. District, community, and state education department documents were analyzed. Since charter schools have existed in the district, numerous activities have taken place. Instructional initiatives included a high school academy, expanded technology, gifted and talented, tutoring, and dropout prevention. All elementary and middle schools required uniforms. The district's state accountability rating improved from acceptable to recognized. A leadership void was perceived due to students …

Hersh (1986) states, "One's conception of what mathematics is affects one's conception of how it should be presented. One's manner of presenting it is an indication of what one believes to be most essential in it." In this research study, three hundred ninety-seven urban early childhood teachers were given a survey that examined their attitudes toward mathematics and mathematics teaching, their views of mathematics, views of teaching mathematics, and views of children learning mathematics. The purpose of this study was to identify the attitudes and beliefs of early childhood teachers in two urban school districts to determine if mathematics reform efforts made a difference in teachers' attitudes and beliefs about mathematics and its teaching. Questionnaires were mailed directly to teachers in one school district and principals distributed questionnaires in the other. Summary scores were calculated for parts of the instrument. The researcher performed descriptive statistics, comparative analysis, and conducted frequency distributions, t-tests, ANOVA, and Pearson Correlations. Findings revealed that teachers with 30 or more years of teaching experience had more positive attitudes toward mathematics than teachers with 1-3 years of experience. African American teachers had more positive attitudes toward mathematics and its teaching than other ethnic groups. Teachers who held …

Predominantly darker than his other works, Cape Cod depicts Henry David Thoreau's interpretation of life as a struggle for survival and a search for salvation in a stark New England setting. Representing Thoreau's greatest test of the goodness of God and nature, the book illustrates the centrality of the subject of death to Thoreau's philosophy of life. Contending that Thoreau's journey to the Cape originated from an intensely personal transcendental impulse connected with his brother's death, this study provides the first in-depth examination of Thoreau's use of the five senses in Cape Cod to reveal both the eccentricities inherent in his relationship with nature and his method of resolving his fears of mortality. Some of the sense impressions in Cape Cod--particularly those that center around human death and those that involve tactile sensations--suggest that Thoreau sometimes tried to master his fears by subconsciously altering painful historical facts or by avoiding the type of sensual contact that aggravated the repressed guilt he suffered from his brother's death. Despite his personal idiosyncrasies, however, Thoreau persisted in his search for truth, and the written record of his journey in Cape Cod documents how his dedication to the transcendental process enabled him to surmount …

TOL plasmids encode enzymes responsible for utilization of toluene and related aromatic compounds by Pseudomonas putida, ultimately converting them to central metabolic intermediates. The nucleotide sequence for the 5.6 kb xylGFJQK region of the pDK1 TOL meta operon was determined. DNA sequence analysis revealed the presence of five open reading frames corresponding to xylG (1458 bp), xylF (846 bp), xylJ (783 bp), xylQ (936 bp) and xylK (1047 bp), encoding predicted protein products of 51.6, 31.3, 27.8, 32.8, and 36.6 kDa in size, respectively. The average G+C content of the xylLTEGFJQK region was 65.7%, somewhat higher than the 58.9% seen in the immediately upstream xylXYZ region and substantially more than the 50% G+C content reported for the upper TOL operon of this plasmid. Homology comparisons were made with genes and proteins of related catabolic plasmids. The dmpCDEFG and pWWO xylGFJQK regions exhibit consistently high levels of nucleotide and amino acid homology to pDK1 xylGFJQK throughout the entire region. In contrast, although the nucleotide sequence homology of the Acinetobacter atdCDE region to xylGFJ is high, the homology of atdFG to xylQK is markedly less. Such radical changes in homology between corresponding regions of different operons, combined with variable base and codon …

Two contrasting notions have been put forward on how social capital may influence individual effectiveness in organizations. Burt (1992) sets forth the informational and control advantages that are possible by building an open network characterized by large numbers of structural holes. In contrast, Coleman (1990) and Simmel (1950) have suggested that network closure, exemplified by large numbers of Simmelian ties, enables actors to develop trust, cohesiveness, and norms which contribute to effectiveness. Simmelian ties are strong, reciprocal ties shared by three actors. It is proposed that an actor's network cannot be dominated by both structural holes and Simmelian ties. Thus, this study examines whether a moderating variable is at work. It is proposed that the actor's task interdependence in the workplace influences the relationship between network closure and individual effectiveness. Actors in less task interdependent environments will benefit especially from the information and control benefits afforded by a network characterized by structural holes. Conversely, actors in highly interdependent environments will benefit especially from the creation of trust and cooperation that result from large numbers of Simmelian ties. Data was collected on 113 subjects in three organizations. Subjects were asked to rate the strength of their relationship with all organization members …

The purpose of this study is to analyze four late solo piano works of Franz Liszt that all bear the name "Mephisto" in their titles, in order to examine, identify and trace the development in the use of harmonic and melodic idioms that produced non-tonal or "omnitonic" effects, on the one hand, and to emphasize the need to duly accord Liszt a recognition of historical position as the nineteenth century's most influential avant garde composer whose attitude and approach had helped to shape much of the ideal of the atonal composition of this century, on the other. Chapter One presents the issues and the purpose of this study; Chapter Two investigates the principal forces that shaped Liszt's mature compositional style; Chapter Three identifies and discusses the requisites for tonal and atonal compositions; Chapter Four analyzes the four "Mephisto" dances: Waltz no.1 (1860); Polka (1883); Waltz no.3 (1883); and Bagatelle (1885). Chapter Five summarizes the findings from this study and attempts to identify in these late works of Liszt a pattern of conscientious, continuous, purposeful and progressive use of devices toward creating musical effect that would defy the established tonal requisites and undermine the tonal orientation in the composition. This study …

Nikolai Medtner's works evidence an intense interest in symmetrical designs. This concern is manifest at all levels, from the large scale proportions of his numerous ingenious sonata forms to the symmetrically constructed themes and motives. Medtner's works include several instances of palindromic themes and periods. Some palindromic contours are achieved through immediate inversion, creating expansive, symmetrical waves. One of Medtner's thumbprints, symmetrical contrary voice-leading, consists of two or more voices which systematically expand or contract in exact mirror fashion. The contrary movement is usually stepwise, and may be either chromatic or diatonic. Occasionally even larger intervals, such as thirds and fourths, are subjected to this favourite mirroring technique. Such symmetrical expansion and contraction often controls the harmonic progression of several consecutive bars. One of the most striking aspects of Medtner's music is his sophisticated harmonic language. He was fascinated with symmetrical harmonic designs, such as the tritone, the French sixth chord, and the octatonic scale, and made endless and increasingly intricate explorations into these stuctures and the ways in which these apparently nontonal, non-hierarchical forms could be coordinated with the fundamental hierarchy of asymmetrical tonal forms, including triads, major and minor scales, and tonic-dominant relations. Medtner's late work, the Grozovaya …

Using Tinto's longitudinal model of institutional departure as the theoretical basis for this research, the purpose was to determine what extent selected motivational factors measured by the College Student Inventory (CSI) predict academic success and persistence of at-risk students at the University of North Texas (UNT). The study focused on United States citizens and permanent residents entering UNT as at-risk first-time freshmen admitted via individual approval for the fall 1994 semester. The 409 subjects were enrolled in a developmental course titled Personal and Academic Effectiveness where the CSI was administered during the first 2 weeks of class. Selected predictor variables were tested in relation to the separate criterion variables of grade point average and enrolled status during the 2nd and 4th years of the study. Grade point averages and enrollment data for the 1995-96 and 1997-98 academic years were extracted from the student information management system. The research design employed appropriate multiple regressions, multiple correlations, multiple discriminant analyses, and bivariate correlations. Findings confirmed the ability of five CSI factors to predict grade point average (p < .05) of at-risk students over the time frames used in this study. Nine factors predicting enrolled status were also significant at the .05 level; …

This dissertation is an exploration of relationships between fiction and history as illuminated by historiographic fiction in general and the historiographic novel in particular. Here the term historiography is employed particularly in several of its many meanings: as the study of the materials and techniques of history, the study of what it means to be a historian, and the study of the philosophy of history. All of these are comprehended in the larger definition of issues pertaining to the writing of history. Four twentieth-century novels are presented and analyzed as historiographic novels. The common element in analysis of all the novels is the examination of historiographic material encoded in narrative, plot, characters, theme, structure or style. Each analysis focuses on one historiographic assumption or problem and brings in perspectives of historians or theorists of history as well as non-novelistic, critical perspectives of the authors themselves. E. M. Forster's Howards End (1910) is analyzed as an imaginative exposé of causality in historical thinking. All the King's Men by Robert Penn Warren (1946) is presented as a gloss on Isaiah Berlin's critique of Leo Tolstoy's second epilogue to War and Peace. Several essays by philosopher Eric Voegelin provide the theoretical framework for …

This research investigated the association between academic lineage and student performance in medical school. The purposes of the study were to: (1) determine whether the Carnegie classifications of medical school applicants' institutions of origin are associated with academic performance in medical school; (2) consider the relationship between the admission selectivity of the schools of origin and the academic performance of medical school students; (3) compare the performance of medical students from institutions under public governing control with students from privately controlled institutions; and (4) establish a model by which the relative academic strengths of applicants from a variety of undergraduate institutions can be understood more clearly based on the previous performance of medical students from schools with similar institutional characteristics. A review of the literature on medical school admissions was completed and used to develop this research. Medical students from the University of Texas Southwestern Medical Center at Dallas who enrolled between the years 1990 and 1994 and graduated or were dismissed between the years 1994 and 1998 were selected as the sample for the study (n=933). The undergraduate institution of origin for each student was coded based on its Carnegie classification, admissions selectivity group, and whether its governing control …

Every day, children throughout the United States are given psychological evaluations for many different clinical and psycho-educational purposes. Very little research has attempted to investigate children's responses to the experience of having intellectual and achievement tests administered. The goal of the current research was to explore the effect a psycho-educational evaluation has on children in areas of self-concept and anxiety. Dependent variables consisted of pre- and post-test measures of anxiety and self-concept. A total of 75 children in the 4th 5th and 6th grades were recruited after referral for evaluation and possible placement in the Talented and Gifted Program or Special Education. This study employed Analysis of Variance (ANOVA), t-tests, multiple regression analysis, and correlational analysis. Findings included initial evidence that children endorsed decreased anxiety after psycho-educational assessments rather than increased anxiety, suggesting that fear of unknown situations may be more anxiety provoking than the actual situation itself, potentially beneficial findings for psychology and psychometric professionals who evaluate children daily. Students endorsement of academic self-concept significantly predicted anxiety after a psycho-educational evaluation, indicating that students who feel capable in academic areas may endorse less anxiety after an evaluation than students who do not feel academically capable. Finally, negative verbal interaction …

In this dissertation, I show how 20th century African-American women writers such as Zora Neale Hurston, Alice Walker, and Toni Morrison utilize animals-as-trope in order to illustrate the writers' humanity and literary vision. In the texts that I have selected, I have found that animals-as-trope functions in two important ways: the first function of animal as trope is a pragmatic one, which serves to express the humanity of African Americans; and the second function of animal tropes in African-American women's fiction is relational and expresses these writers' "ethic of caring" that stems from their folk and womanist world view. Found primarily in slave narratives and in domestic fiction of the 19th and early 20th centuries, pragmatic animal metaphors and/or similes provide direct analogies between the treatment of African-Americans and animals. Here, these writers often engage in rhetoric that challenges pro-slavery apologists, who attempted to disprove the humanity of African-Americans by portraying them as animals fit to be enslaved. Animals, therefore, become the metaphor of both the abolitionist and the slavery apologist for all that is not human. The second function of animals-as-trope in the fiction of African-American women writers goes beyond the pragmatic goal of proving African-Americans's common humanity, even …

An examination of the effectiveness of seeding, burning, and mowing in the reestablishment of tallgrass prairie species on overgrazed and abandoned pastureland. The study site is a 20 acre tract on U.S. Corps of Engineers land below Lake Lewisville in Denton County, Texas. The site was partitioned into thirty-nine 40 by 40 meter plots with seeding (carried out in 1996) and management treatment (burning, mowing, and no maintenance carried out in 1998) randomly applied following a two level design. For each plot, nine stratified-random 0.1 m2 subplots were examined and shoot counts for each species recorded. The effects of the treatments on individual species and species richness were analyzed with a two-way ANOVA followed by a SNK multiple range test, both on ranked data. Community level analysis was conducted with both a MANOVA on ranked data and a Canonical Correspondence Analysis on raw data. Results indicate that seeding positively affected species richness, particularly when combined with either burning or mowing in the early spring. Mowing also significantly increased species richness in areas that were not seeded, while burning negatively affected species richness on unseeded plots. Treatments significantly affected community composition with treatments having the most clear effect on spring and …

The purpose of this study was to investigate if there is a difference in the way male and female authors of contemporary realistic fiction for young adults portray decision making by their male or female protagonists. Questions asked in the study were: (1) Do female writers of contemporary young adult realistic fiction employ an ethic of justice or an ethic of care for male protagonists involved in moral decision making? (2) Do female writers of contemporary young adult realistic fiction employ an ethic of justice or an ethic of care for female protagonists involved in moral decision making? (3) Do male writers of contemporary young adult realistic fiction employ an ethic of justice or an ethic of care for male protagonists involved in moral decision making? and (4) Do male writers of contemporary young adult realistic fiction employ an ethic of justice or an ethic of care for female protagonists involved in moral decision making? Content analysis was used as the method of collecting data. The sample consisted of 194 novels written from 1989 to 1998, 53 of which contained a moral dilemma. A discussion of the novels included examples of moral dilemmas, alternative solutions, dilemma resolutions, and resolutions based …

This dissertation explores the porous boundaries between Salman Rushdie's fiction and the various manifestations of the filmic vision, especially in Midnight's Children, The Satanic Verses, and other selected Rushdie texts. My focus includes a chapter on Midnight's Children, in which I analyze the cinematic qualities of the novel's form, content, and structure. In this chapter I formulate a theory of the post-colonial novel which notes the hybridization of Rushdie's fiction, which process reflects a fragmentation and hybridization in Indian culture. I show how Rushdie's book is unique in its use of the novelization of film. I also argue that Rushdie is a narrative trickster. In my second chapter I analyze the controversial The Satanic Verses. My focus is the vast web of allusions to the film and television industries in the novel. I examine the way Rushdie tropes the "spiritual vision" in cinematic terms, thus shedding new light on the controversy involving the religious aspects of the novel which placed Rushdie on the most renowned hit-list of modern times. I also explore the phenomenon of the dream as a kind of interior cinematic experience. My last chapter explores several other instances in Rushdie's works that are influenced by a filmic …

A culturally-based theoretical model about how cultural beliefs about cancer and breast cancer screening techniques influence the screening behaviors of women of Mexican descent was developed using grounded theory. Across levels of acculturation and socioeconomic status, 34 women (49 to 81 years old) were interviewed through focus groups. Women who hold more traditional health beliefs about causes, nature, and responsibility with regard to breast cancer are more likely to "feel healthy" and not engage in breast cancer screening. Women who hold more traditional beliefs about propriety of female and health care provider behavior are more likely to "feel indecent" and also not engage in screening. The cultural health belief model is integrated within a sociocultural and a socioeconomic context.

The present study is a comparison of music and non-music students with respect to their response patterns on the Brief Symptom Inventory as well as several demographic questions. The sample consisted of 148 non-music students and 141 music students at three levels: (1) freshmen/sophomore; (2) juniors/seniors; and (3) graduate students. Music students consisted of volunteers from several different music classes and non-music students were volunteers from non-music classes. There were no significant differences found among or between groups for the BSI subscales. However, music students were significantly less likely to have gone to counseling in the past and to seek professional counseling for future problems. Recommendations for psycho-educational interventions with musicians are discussed as well as suggestions for future research.

Hartree-Fock, Moller-Plesset, and density functional theory calculations have been carried out using 6-31+G(d), 6-31+G(d,p) and 6-31++G(d,p) basis sets to study the properties of low-barrier or short-strong hydrogen bonds (SSHB) and their potential role in enzyme-catalyzed reactions that involve proton abstraction from a weak carbon-acid by a weak base. Formic acid/formate anion, enol/enolate and other complexes have been chosen to simulate a SSHB system. These complexes have been calculated to form very short, very short hydrogen bonds with a very low barrier for proton transfer from the donor to the acceptor. Two important environmental factors including small amount of solvent molecules that could possibly exist at the active site of an enzyme and the polarity around the active site were simulated to study their energetic and geometrical influences to a SSHB. It was found that microsolvation that improves the matching of pK as of the hydrogen bond donor and acceptor involved in the SSHB will always increase the interaction of the hydrogen bond; microsolvation that disrupts the matching of pKas, on the other hand, will lead to a weaker SSHB. Polarity surrounding the SSHB, simulated by SCRF-SCIPCM model, can significantly reduce the strength and stability of a SSHB. The residual strength …

This paper explores the role of children and childhood in Nathaniel Hawthorne's fiction. Moreover, it asserts that the child and childhood are keys to a better understanding of Hawthorne's fiction.
