Academic Lineage and Student Performance in Medical School
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 was public or private. Because the sample was not randomly selected and the data likely would not meet the assumptions of equal means and variance with the population, nonparametric analyses of variance and multiple comparison tests were completed to compare the groups of the independent variables over each dependent variable. The analyses revealed that for the sample of medical students selected for this study there was an association between academic lineage and student performance in medical school. Differences were found among Carnegie classifications on the dependent variables of cumulative medical school grade point average, class rank, failure rate, and score …
An Adaptive Linearization Method for a Constraint Satisfaction Problem in Semiconductor Device Design Optimization
The device optimization is a very important element in semiconductor technology advancement. Its objective is to find a design point for a semiconductor device so that the optimized design goal meets all specified constraints. As in other engineering fields, a nonlinear optimizer is often used for design optimization. One major drawback of using a nonlinear optimizer is that it can only partially explore the design space and return a local optimal solution. This dissertation provides an adaptive optimization design methodology to allow the designer to explore the design space and obtain a globally optimal solution. One key element of our method is to quickly compute the set of all feasible solutions, also called the acceptability region. We described a polytope-based representation for the acceptability region and an adaptive linearization technique for device performance model approximation. These efficiency enhancements have enabled significant speed-up in estimating acceptability regions and allow acceptability regions to be estimated for a larger class of device design tasks. Our linearization technique also provides an efficient mechanism to guarantee the global accuracy of the computed acceptability region. To visualize the acceptability region, we study the orthogonal projection of high-dimensional convex polytopes and propose an output sensitive algorithm for projecting polytopes into two dimensions.
Adhesion/Diffusion Barrier Layers for Copper Integration: Carbon-Silicon Polymer Films and Tantalum Substrates
The Semiconductor Industry Association (SIA) has identified the integration of copper (Cu) with low-dielectric-constant (low-k) materials as a critical goal for future interconnect architectures. A fundamental understanding of the chemical interaction of Cu with various substrates, including diffusion barriers and adhesion promoters, is essential to achieve this goal. The objective of this research is to develop novel organic polymers as Cu/low-k interfacial layers and to investigate popular barrier candidates, such as clean and modified tantalum (Ta) substrates. Carbon-silicon (C-Si) polymeric films have been formed by electron beam bombardment or ultraviolet (UV) radiation of molecularly adsorbed vinyl silane precursors on metal substrates under ultra-high vacuum (UHV) conditions. Temperature programmed desorption (TPD) studies show that polymerization is via the vinyl groups, while Auger electron spectroscopy (AES) results show that the polymerized films have compositions similar to the precursors. Films derived from vinyltrimethyl silane (VTMS) are adherent and stable on Ta substrates until 1100 K. Diffusion of deposited Cu overlayers is not observed below 800 K, with dewetting occurred only above 400 K. Hexafluorobenzene moieties can also be incorporated into the growing film with good thermal stability. Studies on the Ta substrates demonstrate that even sub-monolayer coverages of oxygen or carbide on polycrystalline Ta significantly degrade the strength of Cu/Ta chemical interactions, and affect the kinetics of Cu diffusion into bulk Ta. On clean Ta, monolayer coverages of Cu will de-wet only above 600 K. A partial monolayer of adsorbed oxygen (3L O2 at 300 K) results in a lowering of the de-wetting temperature to 500 K, while saturation oxygen coverage (10 L O2, 300 K) results in de-wetting at 300 K. Carbide formation also lowers the de-wetting temperature to 300 K. Diffusion of Cu into the Ta substrate at 1100 K occurs only after a 5-minute induction period. This induction period increases …
Adjustment of Kindergarten Children through Play Sessions Facilitated by Fifth Grade Students Trained in Child-Centered Play Therapy Procedures and Skills
This research study investigated the effectiveness of the application of child-centered play therapy procedures and skills by trained fifth grade students in play sessions with kindergarten children who had adjustment difficulties. Specifically, this research determined if play sessions with trained fifth grade students facilitated change in kindergarten children's self concept, internalizing behavior, and externalizing behavior and their parents' stress level.
Affective Reactions and Psychosocial Functioning in the Course of Psycho-Educational Assessment
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 with parents significantly predicted lower general self-concept scores, providing evidence that the manner in which parents verbally relate to their children may have significant impact for the mental health of children.
The Afro-British Slave Narrative: The Rhetoric of Freedom in the Kairos of Abolition
The dissertation argues that the development of the British abolition movement was based on the abolitionists' perception that their actions were kairotic; they attempted to shape their own kairos by taking temporal events and reinterpreting them to construct a kairotic process that led to a perceived fulfillment: abolition. Thus, the dissertation examines the rhetorical strategies used by white abolitionists to construct an abolitionist kairos that was designed to produce salvation for white Britons more than it was to help free blacks. The dissertation especially examines the three major texts produced by black persons living in England during the late eighteenth centuryIgnatius Sancho's Letters of the Late Ignatius Sancho (1782), Ottobauh Cugoano's Thoughts and Sentiments on the Evil of Slavery (1787), and Olaudah Equiano's The Interesting Narrative of the Life of Olaudah Equiano, or Gustavus Vassa, the African (1789)to illustrate how black rhetoric was appropriated by whites to fulfill their own kairotic desires. By examining the rhetorical strategies employed in both white and black rhetorics, the dissertation illustrates how the abolitionists thought the movement was shaped by, and how they were shaping the movement through, kairotic time. While the dissertation contends that the abolition movement was rhetorically designed to provide redemption, and thus salvation, it illustrates that the abolitionist's intent was not merely to save the slave, but to redeem blacks first in the eyes of white Christians by opening blacks to an understanding and acceptance of God. Perhaps more importantly, abolitionists would use black salvation to buy back their own souls and the soul of their nation in the eyes of God in order to regain their own salvation lost in the slave trade. But ironically, they had to appear to be saving others to save themselves. So white abolitionists used the black narratives to persuade their overwhelmingly white audience …
Alec Wilder's music for marimba: a performance guide, a lecture recital, together with three recitals of selected works of G. Stout, N. Zivkovic, D. Erb, W. Kraft, K. Abe, W. Penn and others
The intent of this dissertation is to provide a reference guide for any prospective performer of Alec Wilder's four works for marimba: Suite for Solo Guitar (1976), Suite for Trumpet and Marimba (1977), Suite for Flute and Marimba (1977), and Sextet for Marimba and Wind Quintet (1977). The first part of the dissertation provides background information pertaining to Wilder himself, the works for marimba, and theoretical aspects of Wilder's music. The second part addresses specific performance problems contained in the music. The dissertation culminates with the presentation of a performance edition of the marimba part of the previously unedited Sextet. This dissertation will facilitate and enhance future performances of these works. It is hoped that this document will serve to help perpetuate and sustain interest in these important compositions.
An Analysis of a Title I Inclusive Middle School Program in Texas over a Three Year Period: A Case Study
The purpose of this study was to describe a Title I inclusion program in a north Texas middle school, to evaluate the degree of its success as a high achieving program, and to analyze how closely it met the requirements of the Improving America's Schools Act of 1994. Data were collected from the learning facilitators and teachers at the middle school with the permission of the school district. This study began with extensive research on the nature of adolescents and the beliefs and characteristics of high achieving middle schools. It addressed the steps which were recommended in the literature to improve middle schools and benefit students that are at-risk of failing to master the curriculum at their grade level. The researcher concluded by reporting effective strategies being used in middle school at-risk programs. These are strategies noted by experts as successful in identified programs. The population for this study was seventh and eighth grade Title I students who attended middle school during the 1992-1993, 1993-1994, 1994-1995 and 1995-1996 school years. The data collected by the researcher are presented in two parts: the description of the Title I inclusion program; and the results of the Texas Assessment of Academic Skills tests in reading and math, the Shaw-Hiehle Math Tests, and the Gates-MacGinitie Reading Tests. Findings from this study suggest that the program met the requirements of a Title I program established by the federal government. The test scores for the middle school improved during the three years of the program. The Title I inclusion program met the requirements of the Improving America's Schools Act. Finally, the Title I students were successful working in classrooms with other students on challenging curriculum which met the State's content and performance standards. These findings have implications for other middle schools who are developing Title I …
An Analysis of Program Options for Gifted Middle School Students
The purpose of this study was to compare three different types of programming options for identified gifted and talented middle school students.
An Analysis of Status: Women in Texas, 1860-1920
This study examined the status of women in Texas from 1860 to 1920. Age, family structure and composition, occupation, educational level, places of birth, wealth, and geographical persistence are used as the measurements of status. For purposes of analysis, women are grouped according to whether they were married, widowed, divorced, or single.
An Analysis of the Ability of an Instrument to Measure Quality of Library Service and Library Success
This study consisted of an examination of how service quality should be measured within libraries and how library service quality relates to library success. A modified version of the SERVQUAL instrument was evaluated to determine how effectively it measures library service quality. Instruments designed to measure information center success and information system success were evaluated to determine how effectively they measure library success and how they relate to SERVQUAL. A model of library success was developed to examine how library service quality relates to other variables associated with library success. Responses from 385 end users at two U.S. Army Corps of Engineers libraries were obtained through a mail survey. Results indicate that library service quality is best measured with a performance-based version of SERVQUAL, and that measuring importance may be as critical as measuring expectations for management purposes. Results also indicate that library service quality is an important factor in library success and that library success is best measured with a combination of SERVQUAL and library success instruments. The findings have implications for the development of new instruments to more effectively measure library service quality and library success as well as for the development of new models of library service quality and library success.
Analyzing the Financial Condition of Higher Education Institutions Using Financial Ratio Analysis
The problem concerned the financial indicators used to evaluate the financial condition of the six sister higher education institutions under the authority of the Board of Regents of Oklahoma Colleges. The purposes were to determine the financial ratios that best indicate financial condition; to calculate those financial ratios for the six designated Oklahoma higher education institutions; and to evaluate and compare the financial condition of the six institutions. This study attempted to further the use of financial ratio analysis as an objective addition to subjective studies that examine an institution's definition of its mission, objectives, and goals and its own assessment of the degree to which its resources allow it to attain those goals. The data were obtained from the Integrated Postsecondary Education Data System; the financial reports were audited by independent certified public accountants and presented to the Board of Regents of Oklahoma Colleges; and John Minter Associates, Inc., provided the national norms. The set of financial ratios identified provides a means to study a single higher education institution through trend analysis and in comparison to national norms. It also works well with a sample of homogeneous institutions with interinstitutional comparison. The techniques are intended to provide a general profile of an institution’s financial health. Cause-and-effect ratio analysis has been proposed as another technique to aid administrators in determining changes in their financial statements and what may have caused them. The study identified a set of financial ratios that summarize the financial condition of a higher education institution. The ratios helped to analyze the financial solvency and viability of the six Oklahoma higher education institutions and focused on the ability of the institutions to meet current and future financial requirements. The importance of financial statement analysis should not be underestimated. The understandable format of financial ratios allows virtually any …
The Anglo-American Council on Productivity: 1948-1952 British Productivity and the Marshall Plan
The United Kingdom's postwar economic recovery and the usefulness of Marshall Plan aid depended heavily on a rapid increase in exports by the country's manufacturing industries. American aid administrators, however, shocked to discover the British industry's inability to respond to the country's urgent need, insisted on aggressive action to improve productivity. In partial response, a joint venture, called the Anglo-American Council on Productivity (AACP), arranged for sixty-six teams involving nearly one thousand people to visit U.S. factories and bring back productivity improvement ideas. Analyses of team recommendations, and a brief review of the country's industrial history, offer compelling insights into the problems of relative industrial decline. This dissertation attempts to assess the reasons for British industry's inability to respond to the country's economic emergency or to maintain its competitive position faced with the challenge of newer industrializing countries.
Animals-as-Trope in the Selected Fiction of Zora Neale Hurston, Alice Walker, and Toni Morrison
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 though one could argue that this goal is still present in contemporary African-American fiction. Animals-as-trope also functions to express the African-American woman writer's understanding that 1) all oppressions stem from the same source; 2) that the division between nature/culture is a false onethat a universal connection exists between all living creatures; and 3) that an ethic of caring, or relational epistemology, can be extended to include non-human animals. Twentieth-century African-American writers such as Hurston, Walker, and Morrison participate in what anthropologists term, "neototemism," which is the contemporary view that humankind is part of nature, or a vision that Morrison would …
The Applicability of SERVPERF in Judging Service Quality for Biomedical Information Professionals
The applicability of SERVPERF as a tool for judging the quality of services used by biomedical information professionals was tested using standard statistical procedures. Data was gathered nationally via a combination of electronic and non-electronic forms, from Area Health Education Center (AHEC) information professionals and the results consolidated to provide information for the study. It was determined that SERVPERF was applicable in making judgements about service quality for AHEC information professionals. Their perceptions about service quality tended to have a greater influence than did their level of actual satisfaction on whether or not they planned to use a particular service in the future. There is currently no validated tool available to ascertain the quality of services offered to these valuable members of the rural health care team. This dissertation proposes to provide such a tool, and to serve as a guide or template for other professionals seeking a means to judge service quality in their own disciplines.
Asleep in the Arms of God
A work of creative fiction in the form of a short novel, Asleep in the Arms of God is a limited-omniscient and omniscient narrative describing the experiences of a man named Wafer Roberts, born in Jack County, Texas, in 1900. The novel spans the years from 1900 to 1925, and moves from the Keechi Valley of North Texas, to Fort Worth and then France during World War One, and back again to the Keechi Valley. The dissertation opens with a preface, which examines the form of the novel, and regional and other aspects of this particular work, especially as they relate to the postmodern concern with fragmentation and conditional identity. Wafer confronts in the novel aspects of his own questionable history, which echo the larger concern with exploitative practices including racism, patriarchy, overplanting and overgrazing, and pollution, which contribute to and climax in the postmodern fragmentation. The novel attempts to make a critique of the exploitative rage of Western civilization.
Assembly of Pseudomonas putida Aspartate Transcarbamoylase and Possible Roles of the PyrC' Polypeptide in the Folding of the Dodecameric Enzyme
Aspartate transcarbamoylase (ATCase) of Pseudomonas putida consists of two different polypeptides, PyrB and PyrC' (Schurr et al, 1995). The role of the PyrC' and the assembly of PyrB and PyrC' have been studied. The ATCase made in vitro of P.putida PyrB with P.putida PyrC', and of E.coli PyrB with P.putida PyrC ' were generated under two different conditions, denaturation and renaturation, and untreated. It was found that PyrC' plays a role in the enzymatic regulation by ATP, CTP and UTP. In addition to playing a role in substrate binding, the PyrB polypeptide is also involved in effector binding (Kumar et al., manuscript in preparation). The most energetically preferred form of the P.putida WT is a dodecamer with a molecular mass of 480 kDa. The ratio between the PyrB and the PyrC' is 1:1. In studies of nucleotide binding, it was discovered that the P.putida PyrB was phosphorylated by a protein kinase in the cell extract. In the presence of 20 mM EDTA, this phosphorylation was inhibited and the inhibition could be overcome by the addition of divalent cations such as Zn2+ and Mg2+. This result suggested that the phosphorylation reaction required divalent cations. In the CAD complex of eukaryotes, phosphorylations of the CPSase and the linker region between ATCase and DHOase did not occur in the presence of UTP and it was hypothesized (Carrey, 1993) that UTP and phosphorylation(s) regulated the conformational change in the enzyme complex. Therefore, the same idea was approached with P.putida ATCase, where it was found that 1.0 mM UTP inhibited the phosphorylation of PyrB by more than 50%. These results suggested that the regulation of the conformational change of the P.putida ATCase might be similar to that of CAD. Furthermore, peptide mapping for phosphorylation sites was performed on P.putida ATCase WT, WT --11 amino acids …
Assessment and Analysis of Per Pupil Expenditures: a Study Testing a Micro-Financial Model in Equity and Student Outcome Determination
The purpose of this study was to examine district level financial data to assess equity across districts, to compare equity benchmarks established in the literature using selected functions from the state's financial database, and to determine the predictive value of those functions to the Texas Assessment of Academic Skills (TAAS) tests of 1997.
An Assessment of the Use of Seeding, Mowing, and Burning in the Restoration of an Oldfield to Tallgrass Prairie in Lewisville, Texas
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 summer forbs.
Attribution to Deviant and Nondeviant Social Roles
A questionnaire was used to study causal attribution to social roles as influenced by perceived deviance of the role, instructions to identify with the role, and participant gender. The perceived deviance or nondeviance of the roles was determined by a pilot study. The roles were varied randomly through 12 hypothetical events, and identification or nonidentification instructions randomly assigned. The participants were 194 male and female university students. Participants gave the cause of each event and rated the cause on five dimensions: internality, externality, stability, globality, and controllability. Causal attribution to deviant social roles was found to result in a significantly higher across-scales score and to be more internal, less external, and more global than attribution to nondeviant roles. Participant gender showed an interaction with deviance overall and on the dimensions of stability and globality due to significantly higher ratings by women participants than those by men. Identification instructions did not produce a significant effect.
Authors, Protagonists, and Moral Decision Making in Contemporary Young Adult Realistic Fiction: a Content Analysis
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 upon care or justice. Analysis of the data revealed: (1) Female writers employ an ethic of care and an ethic of justice for male protagonists involved in moral decision making. (2) Female writers prefer an ethic of care for female protagonists involved in moral decision making. (3) Male writers prefer an ethic of justice for male protagonists involved in moral decision making. (4) Male writers prefer an ethic of justice for female protagonists involved in moral decision making.
Benchmarks in American Higher Education: Selected Approaches for Distance Education Copyright and Intellectual Property Policies
An evaluation of American higher education distance education programs was conducted to explore how they approach intellectual property, copyright and information sharing/antitrust policy concerns for Internet-based programs. An evaluation of the current status of distance education and Internet-based training in higher education was conducted through a pilot study that included a random sample of 223 accredited institutions. Seventy-seven institutions responded to a survey, of which there were 14 Research I&II, 17 Doctorate I&II, and 46 Master's I&II institutions included in this study. A review of institutional policy approaches for these 77 institutions was conducted via Internet Web site and bulletin review. A multiple-case study was also conducted which included 10 of the top 30 accredited distance education institutions in America. Policy approaches were examined for all institutions and differences were discussed for public and private institutions as well as the following Carnegie Class institutions- Research I&II, Doctorate I&II and Master's I&II. Ten percent of all institutions that responded to the pilot study developed a written policy addressing antitrust/information-sharing concerns. Additionally, the data indicated that 22% of institutions in these Carnegie Class ranges published copyright and intellectual property policy on their institutions' Internet Web site. Ninety percent of the institutions in the case study advised of central control for the distance education program, as well as central control for copyright and intellectual property policy.
Biodiversity of Dragonflies and Damselflies (Odonata) of the South-Central Nearctic and Adjacent Neotropical Biotic Provinces
The south-central United States serves as an important biogeographical link and dispersal corridor between Nearctic and Neotropical elements of western hemisphere odonate faunas. Its species are reasonably well known because of substantial collections, but there has been no concerted effort to document the extent of biodiversity and possible geographic affinities of dragonflies and damselflies of this region. The recent discoveries of Argia leonorae Garrison, Gomphus gonzalezi Dunkle and Erpetogomphus heterodon Garrison from southern and western Texas and northern Mexico suggest that Odonata species remain to be discovered in this area, particularly from far south Texas and northern Mexico. I have documented a total of 12,515 records of Odonata found in 408 counties within the south-central U.S. A total of 73 species of damselflies and 160 species of dragonflies was revealed in the region. The 233 (197 in Texas) Odonata species are distributed among 10 families and 66 genera. Illustrated family, generic, and species-level keys are provided. Since the beginning of this work in the Fall of 1993, one species has been added each to the Louisiana and Oklahoma faunas, and 12 species have been added, previously unreported from Texas, including four new to the U.S. The area of highest Odonata biodiversity overall (161 spp.) is in the Austroriparian biotic province. The greatest degree of faunal similarity between the south-central U.S. and other intra-continental regions was observed for the eastern (64%) United States. Diversity is a function of area, and as expected, the numbers of breeding birds and Odonata, in each contiguous U.S. state are positively correlated (r=0.376, n=33, p=0.031). There is, however, no strong correlation between land area and species diversity within the region, but those natural biotic provinces (Austroriparian, Texan, Balconian) where aquatic systems and topographic heterogeneity are the greatest provide a broader spectrum of potential Odonata habitats and …
The Blurred Boundaries between Film and Fiction in Salman Rushdie's Midnight's Children, The Satanic Verses, and Other Selected Works
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 vision, with specific examples from Haroun and the Sea of Stories, "The Firebird's Nest," and numerous other articles, interviews, and essays involving Rushdie. In my conclusion I discuss some of the emerging similarities between film and the novel, born out of the relatively recent technology of video cassette recorders and players, and I examine the democratizing effects of this relatively new way of seeing.
Breast Cancer Screening Behaviors of Women of Mexican Descent: A Grounded Theory Approach
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.
Brief Symptom Inventory: Music and Non-Music Students
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.

Characterization of Low Barrier Hydrogen Bonds in Enzyme Catalysis: an Ab Initio and DFT Investigation
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 of a SSHB is about 10--11 kcal/mol that is still significantly stable compared with a traditional weak hydrogen bond that is only about 3--5 kcal/mol in any cases. These results indicate that SSHB can exist under polar environment. Possible reaction intermediates and transition states for the reaction catalyzed by ketosteroid isomerase were simulated to study the stabilizing effect of a SSHB on intermediates and transition states. It was found that at least one SSHB is formed in each of the simulated intermediate-catalyst complexes, strongly supporting the LBHB mechanism proposed by Cleland and Kreevoy. Computational results on the activation energy for …
Chaucer and the Rhetorical Limits of Exemplary Literature
Though much has been made of Chaucer's saintly characters, relatively little has been made of Chaucer's approach to hagiography. While strictly speaking Chaucer produced only one true saint's life (the Second Nun's Tale), he was repeatedly intrigued and challenged by exemplary literature. The few studies of Chaucer's use of hagiography have tended to claim either his complete orthodoxy as hagiographer, or his outright parody of the genre. My study mediates the orthodoxy/parody split by viewing Chaucer as a serious, but self-conscious, hagiographer, one who experimented with the possibilities of exemplary narrative and explored the rhetorical tensions intrinsic to the genre, namely the tensions between transcendence and imminence, reverence and identification, and epideictic deliberative discourse.

Client/Server Systems Performance Evaluation Measures Use and Importance: a Multi-Site Case Study of Traditional Performance Measures Applied to the Client/Server Environment
This study examines the role of traditional computing performance measures when used in a client/server system (C/SS) environment. It also evaluates the effectiveness of traditional computing measures of mainframe systems for use in C/SS. The underlying problem was the lack of knowledge about how performance measures are aligned with key business goals and strategies. This research study has identified and evaluated client/server performance measurements' importance in establishing an effective performance evaluation system. More specifically, this research enables an organization to do the following: (1) compare the relative states of development or importance of performance measures, (2) identify performance measures with the highest priority for future development, (3) contrast the views of different organizations regarding the current or desired states of development or relative importance of these performance measures.
Cognitive Interference in the Perception of Pitch and Loudness in a Five-note Musical Pattern
The purpose of the study was to explore whether musicians experience Garner interference among the auditory dimensions of pitch and loudness. Specifically, the study explored whether the dimensions of intonation and loudness, when presented to musicians in a five-note musical pattern, were perceived as integral or separable in nature.
A Comparative Analysis of Intensive Individual Play Therapy and Intensive Sibling Group Play Therapy with Child Witnesses of Domestic Violence
This study was designed to determine the effectiveness of intensive sibling group play therapy in: (a) improving the self-concept of child witnesses of domestic violence; (b) reducing internalizing behavior problems, such as withdrawal, somatic complaints, anxiety and depression, of child witnesses of domestic violence; (c) reducing externalizing behavior problems, such as aggression and delinquency, of child witnesses of domestic violence; and (d) reducing overall behavior problems of child witnesses of domestic violence. A second objective of this study was to compare the effectiveness of intensive sibling group play therapy and intensive individual play therapy on the above identified dimensions.
Comparative Biochemistry and Evolution of Aspartate Transcarbamoylase from Diverse Bacteria
Aspartate transcarbamoylase (ATCase) catalyzes the first committed step in pyrimidine biosynthesis. Bacterial ATCases are divided into three classes, A, B and C. Class A ATCases are largest at 450-500, are. dodecamers and represented by Pseudomonas ATCase. The overlapping pyrBC' genes encode the Pseudomonases ATCase, which is active only as a 480 kDa dodecamer and requires an inactive pyrC'-encoded DHOase for ATCase activity. ATCase has been studied in two non-pathogenic members of Mycobacterium, M. smegmatis and M. phlei. Their ATCases are dodecamers of molecular weight 480 kDa, composed of six PyrB and six PyrC polypeptides. Unlike the Pseudomonas ATCase, the PyrC polypeptide in these mycobacteria encodes an active DHOase. Moreover, the ATCase: DHOase complex in M. smegmatis is active both as the native 480 kDa and as a 390 kDa complex. The latter lacks two PyrC polypeptides yet retains ATCase activity. The ATCase from M. phlei is similar, except that it is active as the native 480 kDa form but also as 450,410 and 380 kDa forms. These complexes lack one, two, and three PyrC polypeptides, respectively. By contrast,.ATCases from pathogenic mycobacteria are active only at 480 kDa. Mycobacterial ATCases contain active DHOases and accordingly. are placed in class A1 . The class A1 ATCases contain active DHOases while class A2 ATCases contain inactive DHOases. ATCase has also been purified from Burkholderia cepacia and from an E. coli strain in which the cloned pyrB of B. cepacia was expressed. The B. cepacia ATCase has a molecular mass of 550 kDa, with two different polypeptides, PyrB (52 kDa) and PyrC of (39 kDa). The enzyme is active both as the native enzyme at 550 kDa and as smaller molecular forms including 240 kDa and 165 kDa. The ATCase synthesized by the cloned pyrB gene has a molecular weight of 165 kDa composed …
A Comparison of Multivariate Normal and Elliptical Estimation Methods in Structural Equation Models
In the present study, parameter estimates, standard errors and chi-square statistics were compared using normal and elliptical estimation methods given three research conditions: population data contamination (10%, 20%, and 30%), sample size (100, 400, and 1000), and kurtosis (kappa =1,10, 20).
The Computation of Ultrapowers by Supercompactness Measures
The results from this dissertation are a computation of ultrapowers by supercompactness measures and concepts related to such measures. The second chapter gives an overview of the basic ideas required to carry out the computations. Included are preliminary ideas connected to measures, and the supercompactness measures. Order type results are also considered in this chapter. In chapter III we give an alternate characterization of 2 using the notion of iterated ordinal measures. Basic facts related to this characterization are also considered here. The remaining chapters are devoted to finding bounds fwith arguments taking place both inside and outside the ultrapowers. Conditions related to the upper bound are given in chapter VI.
Conceptualizations of Young, Middle-aged, and Older Adults and the Ingroup-outgroup Complexity Effect
The purpose of the present study was to investigate Linville's (1982) ingroup-outgroup complexity hypothesis through descriptive card sorts created by young, middle-aged, and older adults regarding their own and other age groups.
Continuity Expectations in Vertical Marketing Systems: a Dyadic Perspective of Domestic and International Franchising
An emerging paradigm shift in the marketing discipline has prompted renewed research interest in the nature and scope of exchange. A common theme in the research to date is a departure from the traditional transactional orientation to a relational perspective of exchange. The relational emphasis is particularly germane to contractual Vertical Marketing Systems (VMS) where the emphasis is on long-term, mutually beneficial interaction between various channel members. The franchisor-franchisee relationship, a type of contractual VMS, is governed by norms that impact system efficiency and effectiveness. Despite the unprecedented growth of international franchising systems in the marketplace, a paucity of empirical attention has focused on cross-national franchisor-franchisee relationships. With many U.S.-based business format franchisors penetrating foreign markets, the primary purpose of the dissertation is to provide insights into tools which franchisors, and franchisees can use during the evolution of the exchange relationship. To identify differences across geographic boundaries, the dissertation simultaneously studies domestic and cross-border franchisor-franchisee relationships.
Counselor Effectiveness and Correlations With Select Demographic Variables for Masters Level Counseling Students
Counselor education programs are charged with the responsibility to train students to be effective counselors. Despite relative consistency in academic and clinical experiences, some students are less effective than others. It was the intent of this research to investigate possible relationships which may exist between students' background and experiences and their levels of demonstrated counselor effectiveness as measured by the Counselor Rating Form - Short Version (CRF-S) and the Supervisor Rated-Counselor Interaction Analysis (SR-CIA). It was hypothesized that counselor effectiveness would be negatively correlated with prior teaching experience and level of religious participation. Data was collected using a demographic survey from masters level counseling students participating in their practicum semester. Counseling tapes from each of the participants were collected towards the end of the semester. These tapes were then rated by doctoral students using the CRF-S and the SR-CIA. The total sample size was 28. Regression analysis was used to investigate the hypotheses. Three models were constructed. The dependent variables used were scores from the CRF-S, the SR-CIA and a third comprised of a normalized composite of CRF-S and SR-CIA termed COMPOSITE. Each model used, as the independent variables, years of teaching experience, and hours of religious participation. Results from regression analysis suggested that a negative correlation existed between counseling effectiveness and years of teaching experience and a positive correlation between counselor effectiveness and hours of religious participation. Statistically significant results were not achieved for any of the models tested. Further investigation was conducted using effect size analysis. Small to medium effect sizes were achieved, however, suggesting that the models were detecting a negative correlation between counselor effectiveness and years of teaching experience, and a positive correlation between hours of religious participation and counselor effectiveness.
Countable Additivity, Exhaustivity, and the Structure of Certain Banach Lattices
The notion of uniform countable additivity or uniform absolute continuity is present implicitly in the Lebesgue Dominated Convergence Theorem and explicitly in the Vitali-Hahn-Saks and Nikodym Theorems, respectively. V. M. Dubrovsky studied the connection between uniform countable additivity and uniform absolute continuity in a series of papers, and Bartle, Dunford, and Schwartz established a close relationship between uniform countable additivity in ca(Σ) and operator theory for the classical continuous function spaces C(K). Numerous authors have worked extensively on extending and generalizing the theorems of the preceding authors. Specifically, we mention Bilyeu and Lewis as well as Brooks and Drewnowski, whose efforts molded the direction and focus of this paper. This paper is a study of the techniques used by Bell, Bilyeu, and Lewis in their paper on uniform exhaustivity and Banach lattices to present a Banach lattice version of two important and powerful results in measure theory by Brooks and Drewnowski. In showing that the notions of exhaustivity and continuity take on familiar forms in certain Banach lattices of measures they show that these important measure theory results follow as corollaries of the generalized Banach lattice versions. This work uses their template to generalize results established by Bator, Bilyeu, and Lewis.
Cultural Influences on the ABC Implementation Under Thailand's Environment
This study examines the influences of culture on the implementation of a U.S.-based Activity-Based Costing (ABC) in three Thai organizations.
Current and Future Trends in Computer Use in Elementary School Settings
The study examined current and future trends in computer use in elementary school settings. A survey instrument was developed and validated for distribution to a random sample of 200 technology coordinators in the public school districts in the state of Texas from whom 95 responses were received. The survey instrument was used to obtain information about five areas of computer use in elementary schools. These areas are: physical configurations, instructional uses, implementation issues, training and staff development, and Internet use. The study found that all public school districts that participated in the study have acquired computer hardware in their elementary schools. In addition, some other advanced computer technology components are starting to be found in elementary schools, such as teacher workstations, CD-ROM, interactive video, computer multimedia, LCD panels, and laser printers. Respondents reported that elementary school teachers in their districts have incorporated computers into their classrooms as an instructional tool and many changes have occurred in teachers’ teaching styles due to computers. However, there are some problems that hinder the effective use of computers. The major problem is lack of training. A high percentage of respondents, 81.3%, indicated that the majority of their elementary school teachers had completed less than 30 hours of technology related professional development. Another problem was lack of funding which prevents most school districts from acquiring computer hardware and software. Currently, elementary schools in 87% of districts that participated in the study are connected to the Internet and the plan is that by the year 2001 all elementary schools will be connected.
Customer Induced Uncertainty and Its Impact on Organizational Design
How firms facing environmental uncertainty should organize their activities remains an important and challenging question for today's managers and organizational researchers. Proponents of contingency theory have argued that organizations must adjust their activities to fit the level of environmental uncertainty to ensure long-term survival. Although much work has been done on contingency theory, it is clear that our understanding of uncertainty is far from complete. One important aspect of today's organizations is their focus on service, mass customization, and continuous innovation. This focus often results in the customer being brought either into the organization or at least into closer contact with it. Even though the literature provides numerous evidences of the increasing customer focus, it is yet to empirically explain how the complications of customer-organizational interactions might create uncertainty for contemporary organizations. The traditional measure of uncertainty still considers customers as an environmental factor causing demand uncertainty while ignoring the complex nature of customer and organizational encounters. Seeking to further refine the concept of uncertainty and focusing on the contemporary business phenomena, this study develops measures aspects of customer induced uncertainty and examines their relationships with three organizational design variables. Specifically, this study explains the complicated nature of customer - organizational encounters that creates organizational uncertainty. Also, this study develops three operational measurement instruments for the three aspects of customer induced uncertainty. Finally, this study shows specific relationships between aspects of customer induced uncertainty and specific organizational design variables. This study conducted a mail survey of middle level managers. With a sample size of 118 the measurement instruments were shown to have validity and reliability using factor analysis and Cronbach's alpha. Regression analyses indicate the presence of specific rather than general relationship between customer induced uncertainty variables and organizational design variables. Regression results suggested that the relationships between customer induced …
A Descriptive Study of Students Who Were Accepted for Admission at West Texas A&M University But Did Not Enroll
Each year, institutions of higher education devote valuable financial and personnel resources in the hope of enhancing student recruitment and matriculation. The purpose of this study was to examine the demographic characteristics, the factors that influenced students’ decisions to apply for admission to a university, their educational intentions, and their reasons for not enrolling after they had been admitted. The subjects of the study were first-time freshmen accepted for admission to a mid-size, public, southwestern university who did not enroll for the fall 1997 semester. Statistically significant differences were found when comparing no-shows and enrolled students by gender, ethnicity, age, ACT/SAT score, and distance of their hometown from the university. There were more female no-shows, and more males enrolled than females; a greater percentage of no-shows reported the distance of their hometown to be more than 200 miles; and the mean test score for no-shows was higher. Factors important in the college selection process found to be statistically significant among the groups were: a greater percentage of Minorities than Caucasians reported the importance of the financial aid award or a scholarship offer; students living within 100 miles of the campus reported the proximity of the university as important, advice received from current or former students and high school counselors was more important to those living more than 100 miles from the campus. Cost of attendance and scholarships were important to students with the higher test scores. Statistically significant reasons cited by the no-shows for not enrolling were more Minorities than Caucasians reported financial difficulties and job demands; students living farther from the campus reported attending other universities while those living within 100 miles reported attending a community college. Recommendations the university studied could pursue include: developing a program to follow-up on the no-shows, directing more energy at recruiting students living …
Developing Criteria for Extracting Principal Components and Assessing Multiple Significance Tests in Knowledge Discovery Applications
With advances in computer technology, organizations are able to store large amounts of data in data warehouses. There are two fundamental issues researchers must address: the dimensionality of data and the interpretation of multiple statistical tests. The first issue addressed by this research is the determination of the number of components to retain in principal components analysis. This research establishes regression, asymptotic theory, and neural network approaches for estimating mean and 95th percentile eigenvalues for implementing Horn's parallel analysis procedure for retaining components. Certain methods perform better for specific combinations of sample size and numbers of variables. The adjusted normal order statistic estimator (ANOSE), an asymptotic procedure, performs the best overall. Future research is warranted on combining methods to increase accuracy. The second issue involves interpreting multiple statistical tests. This study uses simulation to show that Parker and Rothenberg's technique using a density function with a mixture of betas to model p-values is viable for p-values from central and non-central t distributions. The simulation study shows that final estimates obtained in the proposed mixture approach reliably estimate the true proportion of the distributions associated with the null and nonnull hypotheses. Modeling the density of p-values allows for better control of the true experimentwise error rate and is used to provide insight into grouping hypothesis tests for clustering purposes. Future research will expand the simulation to include p-values generated from additional distributions. The techniques presented are applied to data from Lake Texoma where the size of the database and the number of hypotheses of interest call for nontraditional data mining techniques. The issue is to determine if information technology can be used to monitor the chlorophyll levels in the lake as chloride is removed upstream. A relationship established between chlorophyll and the energy reflectance, which can be measured by satellites, enables …
Development and Validation of the Checklist for Differential Diagnosis of Attentional Problems
The current study discussed the development and validation of the Checklist for Differential Diagnosis of Attentional Problems (CDDAP), a tool for use with adults seeking diagnosis and treatment of an Attention Deficit Hyperactivity Disorder. Normative data are provided on three subject groups (ADHD adults, controls, and adults with other psychiatric disorders). Convergent validity was established with the SCL-90, and criterion validity established through comparing scaled scores with final diagnoses. Overall, this measure was accurate at differentiating adults with ADHD from controls and adults with other psychiatric disorders. Results indicated that the CDDAP was also able to identify other psychiatric disorders with 71 to 92% accuracy, depending on the disorder.
Development of Cardiovascular Regulation in Embryos of the Domestic Fowl (Gallus Gallus), with a Partial Comparison to Embryos of the Desert Tortoise (Gopherus Agassizii)
In adult vertebrates, cardiovascular regulation is accomplished by numerous systems with neural, hormonal and local components responsible for the majority of regulation. These regulatory components work in concert to maintain the essential function of blood perfusion to adult tissues. Given the essential nature of this function it is therefore surprising that the development of cardiovascular regulation during gestation is poorly understood. The majority of what is known is based on a single vertebrate model, the fetal lamb. The fetal lamb has been used in multiple studies due to the clear clinical applications and has been pivotal in understanding the onset of regulation in developing vertebrates. However, study on the fetal lamb is limited to the latter 40% of gestation and has the added complication of an in-utero developmental strategy. Therefore the primary focus of this dissertation was to characterize basic cardiovascular regulation in the chicken embryo to provided the needed information for it's use an alternative to the fetal lamb. Developing chicken embryos rely on both alpha and beta adrenergic tones to maintain normal heart rate and arterial blood pressure during incubation. However, on day 21, just prior to hatch, these animals lose both tones on arterial pressure suggesting the onset of adult regulation. Cholinergic tone, however, was absent throughout chicken development indicating that it must mature during the neonatal life. Adult cardiovascular reflexes become apparent late in chicken development with a clear baroreflex specifically operating initially on day. However, an adult response to changes in ambient gas tension was absent during incubation suggesting embryos possess unique regulatory systems that are absent in adult chickens. This mechanism is comprised entirely of adrenergic systems with no cholinergic action during change in ambient gas tension. Similar developmental patterns were determined in embryos of the desert tortoise suggesting fundamental differences between in-utero and …
A Different Drummer: A Chamber Opera
A Different Drummer is a chamber opera adaptation of Donald Davis's story "A Different Drummer" from his collection Listening for the Crack of Dawn, published by August House. The opera lasts about seventy minutes, and calls for a cast of three and an orchestra of sixteen players. It contains a prologue, epilogue and four scenes in a single act. The score is prefaced by a paper describing the musical strategies employed in setting the story as an opera. Three chapters describe the adaptation from short story to opera, the essential musical elements, and details of the application of the musical elements in each scene of the opera. The libretto is presented in the fourth chapter.
A Discrimination of Software Implementation Success Criteria
Software implementation projects struggle with the delicate balance of low cost, on-time delivery and quality. The methodologies and processes used to create and maintain a quality software system are expensive to deploy and result in long development cycle-time. However, without their deployment into the software implementation life-cycle, a software system will be undependable, unsuccessful. The purpose of this research is to identify a succinct set of software implementation success criteria and assess the key independent constructs, activities, carried out to ensure a successful implementation project. The research will assess the success of a software implementation project as the dependent construct of interest and use the software process model (methodology) as the independent construct. This field research involved three phases: (1) criteria development, (2) data collection, and (3) testing of hypotheses and discriminant analysis. The first phase resulted in the development of the measurement instruments for the independent and dependent constructs. The measurement instrument for the independent construct was representative of the criteria from highly regarded software implementation process models and methodologies, e.g., ISO9000, Software Engineering Institute's Capability Maturity Model (SEI CMM). The dependent construct was developed from the categories and criteria from the Delone and McLean (1992) MIS List of Success Measures. The data collection and assessment phase employed a field survey research strategy to 80 companies involved in internal software implementation. Both successful and unsuccessful software implementation projects (identified by the Delone/McLean model) participated. Results from 165 projects were collected, 28 unsuccessful and 137 successful. The third phase used ANOVA to test the first 11 hypotheses and employed discriminant analysis for the 12th hypothesis to identify the "best set" of variables, criteria, that discriminate between successful and unsuccessful software implementation projects. Twelve discriminating variables out of 67 were identified and supported as significant discriminators between successful and unsuccessful projects. …
