Academic Achievement: Examining the Impact of Community Type at a Small Liberal Arts College in Texas
Hierarchical regression was used to determine if high school community type is an effective predictor of academic success when controlling for demographics, prior academic achievement, socioeconomic status, and current commitment or work habits for students entering Austin College in 1992,1993, and 1994 . Findings revealed that there is a relationship between attending high school in community types of rural and independent town controlling for the effects of SAT scores, high school rank, sex, and late application deposit on first semester grade point average. digital.library.unt.edu/ark:/67531/metadc279165/
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 on Step 1 of the United States Medical Licensure Examination. Further, it was found that admission selectivity was also associated with student performance in medical school for each dependent variable except failure rate. Finally, the study results indicated no association between public or private governing control and student performance in medical school. digital.library.unt.edu/ark:/67531/metadc2206/
N-Acylethanolamines and Plant Phospholipase D
Recently, three distinct isoforms of phospholipase D (PLD) were identified in Arabidopsis thaliana. PLD α represents the well-known form found in plants, while PLD β and γ have been only recently discovered (Pappan et al., 1997b; Qin et al., 1997). These isoforms differ in substrate selectivity and cofactors required for activity. Here, I report that PLD β and γ isoforms were active toward N-acylphosphatidylethanolamine (NAPE), but PLD α was not. The ability of PLD β and γ to hydrolyze NAPE marks a key difference from PLD α. N-acylethanolamines (NAE), the hydrolytic products of NAPE by PLD β and γ, inhibited PLD α from castor bean and cabbage. Inhibition of PLD α by NAE was dose-dependent and inversely proportional to acyl chain length and degree of unsaturation. Enzyme kinetic analysis suggested non-competitive inhibition of PLD α by NAE 14:0. In addition, a 1.2-kb tobacco (Nicotiana tabacum L.) cDNA fragment was isolated that possessed a 74% amino acid identity to Arabidopsis PLD β indicating that this isoform is expressed in tobacco cells. Collectively, these results provide evidence for NAE producing PLD activities and suggest a possible regulatory role for NAE with respect to PLD α. digital.library.unt.edu/ark:/67531/metadc279270/
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 to 10 min for partially oxidized Ta, 15 min for carbidic Ta and 20 min for fully oxidized Ta. digital.library.unt.edu/ark:/67531/metadc2255/
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. digital.library.unt.edu/ark:/67531/metadc278097/
Adlerian Personality Priorities of Siblings of Individuals with Tourette Syndrome
This study was designed to examine Adlerian personality priorities of siblings of individuals with Tourette Syndrome (TS). This study aimed to investigate whether a difference exists between TS siblings and siblings of those without disabilities on variables related to personality priorities. It was hypothesized that TS siblings would score significantly higher than the control group on the superiority and pleasing personality priorities and significantly lower on the comfort and control personality priorities. Both of the hypotheses were rejected. First, no significant difference was found between TS siblings and the control group on the superiority and pleasing personality priorities. Second, no significant difference was found between TS siblings and the control group on the comfort personality priority, and TS siblings scored significantly higher than the control group on the control personality priority. digital.library.unt.edu/ark:/67531/metadc278606/
Adolescent Pregnancy: Voices Heard in the Everyday Lives of Pregnant Teenagers
The purpose of this study is to examine the problems that pregnant teenagers encounter at school and at home while they are trying to complete their high school education. Data were collected by in-depth interviews. Twenty pregnant adolescents, who were between the ages of 15 through 18, and were participants in a special teen pregnancy program were interviewed. The major findings in this study included the respondents': 1) unstable family life histories, 2) denial that they were pregnant, 3) need for self-identity as an adult, 4) conflict with parents and 5) motivation to complete their high school education. This study points to the need for more research on the problems that pregnant adolescents encounter in their everyday lives. digital.library.unt.edu/ark:/67531/metadc279259/

Adult Attention Deficit Hyperactivity Disorder Personality Characteristics and Comorbidity
Attention-deficit/hyperactivity disorder (ADHD) is surrounded by confusion and controversy regarding its definition, course, etiology and treatment. Among adults, ADHD is rarely considered a diagnostic reality of primary importance and is often overlooked. This study provides descriptive validity for adult ADHD in distinguishing it from controls, and identifying both a pure condition and one wrought with comorbidity. digital.library.unt.edu/ark:/67531/metadc279399/
An Adult Educational Research Model for Developing an Evaluation System for Clergy
Formal job performance evaluation of a church's pastoral staff has been almost nonexistent in many churches. While business and education have been making strides in evaluation techniques during the past three decades, the church is just beginning to notice the need for this kind of accountability and ongoing professional development. In this research, the author applied the evaluation techniques of education to church pastoral staff members. Evaluation can be understood as both a formative process and a summative decision. The steps to planning an evaluation that will be both formative and summative are discussed. Qualifying the ministerial tasks through objective job descriptions will enable the church to quantify the job performance through evaluation. Suggestions are given for developing a ministerial evaluation instrument. In this research a model from educational evaluation was adapted for use in a local church setting. One denomination was selected to demonstrate the process of evaluation development. Denominational governments differ considerably. Therefore, the key stakeholders of the church for the chosen denomination were identified as pastors and church board members. These stakeholders were used as a "panel of experts." The Delphi technique was used to develop consensus from the participants concerning (1) the core skills of ministerial effectiveness and (2) the quality indicators to measure those core skills. This required two rounds, one for identifying the core skills and one for identifying quality indicators. Each round consisted of three surveys. The research identified seven core skills for ministerial effectiveness and a number of quality indicators to measure each core skill. The results were used to demonstrate how an evaluation tool could be developed from the data. This evaluation tool was the consensus of the panel of experts in this study. While the process is a model that could be similar for any church's "panel" of participants, the resulting core skills, quality indicators and evaluation tool would vary for each "panel". digital.library.unt.edu/ark:/67531/metadc277930/
Advanced Molecular and Microbial Techniques: a Complete Laboratory Notebook

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. digital.library.unt.edu/ark:/67531/metadc2210/
African-American Senior Administrators of Colleges and Universities in American Higher Education: Identification of Characteristics in Their Career Progression
This study identified and compared characteristics in the career progression of African-American college presidents of institutions in the continental United States. The study was concerned with personal, educational and professional characteristics of these senior level administrators. From a population of 141 individuals, 73 presidents participated in this study. Frequencies, means, percentages, chi-square, crosstabulations and analysis of variance (ANOVA) were employed in the analysis of data. The level of significance was set at 0.05. digital.library.unt.edu/ark:/67531/metadc277660/
The Afro-British Slave Narrative: The Rhetoric of Freedom in the Kairos of Abolition
Access: Use of this item is restricted to the UNT Community.
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 that slavery was as bad for them as it was for the African slave. And in the process, a corpus of black writing was produced that gives current readers two glimpses of one world. digital.library.unt.edu/ark:/67531/metadc2278/
AIDS Preventative Behavior Among Taiwanese University Students
This study used the Health Belief Model to examine the predictors of AIDS preventive behavior. The independent variables were the variables of individual perception, modifying factors (psychological variables), and likelihood variables. The respondents, the Taiwanese students of the University of North Texas, were influenced both by Chinese sexuality and Western values in their AIDS-risk behavior. The results revealed that 90% of the respondents were misinformed on the availability of AIDS vaccine. In addition, a majority of the students were either abstaining from sex or practicing monogamy. Using Pearson's correlation coefficient and multiple regression analysis, this study found that the psychological variables rather than cognitive variables significantly influenced the respondents' AIDS preventive behavior. Finally, suggestions were made for future research on AIDS, and for AIDS preventive behavior campaigns. digital.library.unt.edu/ark:/67531/metadc279286/
Alcohol Use, Violence, and Psychological Abuse in Intimate Relationships
Women in distressed relationships who had sustained severe psychological abuse and either no, moderate, or severe violence from their partner were included (N = 93). Men's and women's alcohol use did not differ with level of violence. Different patterns were found in the moderate violence group regarding women's beliefs about their partner's substance problem, men's psychological abuse, and the relationship of men's and women's quantity of alcohol use and times intoxicated. Uncertainty resulting from moderate violence may strengthen the emotional impact of psychological abuse. Even when psychological abuse is exacerbated by violence, women may use active coping techniques rather than drinking to cope with abusive relationships. The findings suggest that an inordinate focus on alcohol abuse may be ineffective in combating the problem of domestic violence. digital.library.unt.edu/ark:/67531/metadc279331/

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. digital.library.unt.edu/ark:/67531/metadc2245/
An Analysis of the Impact of Curriculum Management Audits on Public School Systems in Texas
The purposes of this study were to (1) identify the recommendations of Curriculum Management Audits conducted in Texas Public School systems, (2) determine the degree to which each of the recommendations had been implemented, and (3) determine the perceptions of stakeholders as to the factors instrumental in the real and potential impact of the audit. The researcher conducted interviews with superintendents and key central office administrators with a working knowledge of the audit report in each of the eleven Texas school districts studied. Respondents were asked to rate recommendations written for their districts using the following descriptors: Implemented, In Progress, Plan to Implement, Recommendation Modified, No Implementation. The ranking of recommendation implementation revealed that 85% of the recommendations made in the 11 audit reports reviewed in this study had received action toward implementation to some degree. Respondents were also asked to cite factors which facilitated or impeded recommendation implementation. Significant factors facilitating the implementation of recommendations were reported to be time, organizational structure/personnel and planning. The analysis of the collective recommendations revealed that school board policies were not adequate to direct the design, delivery and monitoring of curriculum when measured against audit Standard One criteria. School districts in Texas rely on the Texas Association of School Boards' policy division for policies. Findings indicate that greater alignment between the Texas Association of School Boards' policies and Curriculum Management Audit criteria must be sought in order for school districts in Texas to meet this Standard. System-wide planning, curriculum documents, and program-driven budgeting processes were other areas requiring attention of the school districts in the study. Evidence of the extent of implementation of recommendations suggests that school districts valued the audit report with its recommendations. It can be generally concluded that the Curriculum Management Audit had a positive impact on the involved school districts. digital.library.unt.edu/ark:/67531/metadc277718/
An Analysis of the Performance of a Clinical Sample of African American, Caucasian, and Hispanic Children on the WISC-III

Analysis of the Trypanosoma brucei Genome and Identification and Characterization of a Gene Family Encoding Putative EF-Hand Calcium-Binding Proteins
The flagellum of Trypanosoma brucei contains a family of antigenically related EF-hand calcium-binding proteins which are called the calflagins. Genomic Southern blots indicated that multiple copies of calflagin genes occur in T brucei. All of the copies were contained in a single 23 kb Xhol-Xhol fragment. Genomic fragments of 2.5 and 1.7 kb were cloned that encoded calflagin sequences. Two new members of the calflagin family were found from genomic clone sequences. The deduced amino acid sequences of the genomic clones showed the calflagin genes were arranged tandemly along the genomic fragments and were similar to previously described calflagins. The calflagin genes were related by two unrelated 3' flanking sequences. An open reading frame that was unrelated to any calflagin was found at the 5' end of the 2.5 kb genomic fragment. Each encoded protein (~24,000u) contained three EF-hand calcium-binding motifs and one degenerate EF-hand motif. In general, variability among the T. brucei calflagins is greater than related proteins in T. lewisii and T. cruzi. This variability results from amino acid substitutions at the amino and carboxy termini, and duplication of internal segments. digital.library.unt.edu/ark:/67531/metadc278592/
Analysis of Thermoplastic Polyimide + Polymer Liquid Crystal Blends
Thermoplastic polyimides (TPIs) exhibit high glass transition temperatures (Tgs), which make them useful in high performance applications. Amorphous and semicrystalline TPIs show sub-Tg relaxations, which can aid in improving strength characteristics through energy absorption. The a relaxation of both types of TPIs indicates a cooperative nature. The semicrystalline TPI shows thermo-irreversible cold crystallization phenomenon. The polymer liquid crystal (PLC) used in the blends is thermotropic and with longitudinal molecular structure. The small heat capacity change (ACP) associated with the glass transition indicates the PLC to be rigid rod in nature. The PLC shows a small endotherm associated with the melting. The addition of PLC to the semicrystalline TPI does not significantly affect the Tg or the melting point (Tm). The cold crystallization temperature (Tc) increases with the addition of the PLC, indicating channeling phenomenon. The addition of PLC also causes a negative deviation of the ACP, which is another evidence for channeling. The TPI, PLC and their blends show high thermal stability. The semicrystalline TPI absorbs moisture; this effect decreases with the addition of the PLC. The absorbed moisture does not show any effect on the degradation. The addition of PLC beyond 30 wt.% does not result in an improvement of properties. The amorphous TPI + PLC blends also show the negative deviation of ACP from linearity with composition. The addition of PLC causes a decrease in the thermal conductivity in the transverse direction to the PLC orientation. The thermomechanical analysis indicates isotropic expansivity for the amorphous TPI and a small anisotropy for the semicrystalline TPI. The PLC shows large anisotropy in expansivity. Even 5 wt. % concentration of PLC in the blend induces considerable anisotropy in the expansivity. Thus, blends show controllable expansivity through PLC concentration. Amorphous TPI + PLC blends also show excellent film formability. The amorphous TPI blends show good potential for applications requiring high thermal stability, controlled expansivity and good film formability. digital.library.unt.edu/ark:/67531/metadc279285/
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 stakeholder to acquire a basic comprehension of the most critical financial policies of institutions and their financial condition. digital.library.unt.edu/ark:/67531/metadc2194/

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. digital.library.unt.edu/ark:/67531/metadc279256/
Animals-as-Trope in the Selected Fiction of Zora Neale Hurston, Alice Walker, and Toni Morrison
Access: Use of this item is restricted to the UNT Community.
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 most likely attribute to the "folk." This perspective places their celebration of the continuous relations between humans and animals within a spiritual, indeed, tribal, cosmological construction. What makes these particular writers primarily different from their literary mothers, however, is a stronger sense that they are reclaiming the past, both an African and African-American history. What I hope to contribute with this dissertation is a new perspective of African-American women writers' literary tradition via their usage of animals as an expression of their "ethic of caring" and their awareness that all oppression stems from a single source. digital.library.unt.edu/ark:/67531/metadc2227/
Anti-Semitism and Der Sturmer on Trial in Nuremberg, 1945-1946: The Case of Julius Streicher
The central focus of this thesis is to rediscover Julius Streicher and to determine whether his actions merited the same punishment as other persons executed for war crimes. Sources used include Nuremberg Trial documents and testimony, memoirs of Nazi leaders, and other Nazi materials. The thesis includes seven chapters, which cover Streicher's life, especially the prewar decades, his years out of power, and his trial at Nuremberg. The conclusion reached is that Streicher did have some influence on the German people with his anti-Semitic newspaper Der Sturmer, but it is difficult to ascertain whether his speeches and writings contributed directly to the extermination of the Jews in World War II or simply reflected and magnified the anti-Semitism of his culture. digital.library.unt.edu/ark:/67531/metadc279213/
Anyone Lived in a Pretty How Hell: the Rhetoric of Universality in Bessie Head
This dissertation approaches the work of South African/Botswanan novelist Bessie Head, especially the novel A Question of Power, as positioned within the critical framework of the postcolonial paradigm, the genius of which accommodates both African and African American literature without recourse to racial essentialism. A central problematic of postcolonial literary criticism is the ideological stance postcolonial authors adopt with respect to the ideology of the metropolis, whether on the one hand the stances they adopt are collusive, or on the other oppositional. A key contested concept is that of universality, which has been widely regarded as a witting or unwitting tool of the metropolis, having the effect of denigrating the colonial subject. It is my thesis that Bessie Head, neither entirely collusive nor oppositional, advocates an Africanist universality that paradoxically eliminates the bias implicit in metropolitan universality. digital.library.unt.edu/ark:/67531/metadc278802/
The Apostasy (and Return) of Lenny Gorsuch
This comic romantic novel engages the question of how the Christianity of the southern, fundamentalist world of the Texas bible belt, finding its primary cultural assumptions about human existence challenged by the more confusing elements of a modern sensibility, a sensibility over-laden with strange-attractors, mechanistic psychologies, relativistic physics and ethics, evolutionary premises, newly proclaimed rights and freedoms, a deterioration in cultural political naivete, and the advent of an increasingly incomprehensible set of technologies, can survive. The "central" character is a young, slightly deformed man raised by his ostensibly "Christian" grandparents who, through a rather odd set of legal circumstances and physical events, not only become wealthy, but somewhat powerful in their immediate community. He finds himself involved with a young woman, raised in an equally "Christian" household, but, as is true of any romantic plot, the relationship between the two is destined, by virtue of circumstance and the meddling of other characters, to struggle and mishap. In the end, the text, in its own fashion, asserts that the Christian impulse can survive the modern era by virtue of one of its central tenets: faith, in the Christian world, is very much the same as life itself, a process of waiting and expecting. Its greatest threat, rather than something intrinsic to the modern period, is perhaps that of the dogmatism and misunderstanding of the characters who most loudly proclaim it to others. digital.library.unt.edu/ark:/67531/metadc278336/
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. digital.library.unt.edu/ark:/67531/metadc279133/
Application of Synthetic Peptides as Substrates for Reversible Phosphorylation
Two highly homologous synthetic peptides MLC(3-13) (K-R-A-K-A-K-T-TK-K-R-G) and MLC(5-13) (A-K-A-K-T-T-K-K-R-G) corresponding to the amino terminal amino acid sequence of smooth muscle myosin light chain were utilized as substrates for protein kinase C purified from murine lymphosarcoma tumors to determine the role of the primary amino acid sequence of protein kinase C substrates in defining the lipid (phosphatidyl serine and diacylglycerol) requirements for the activation of the enzyme. Removal of the basic residues lysine and arginine from the amino terminus of MLC(3-13) did not have a significant effect on the Ka value of diacylglycerol. The binding of effector to calcium-protein kinase C appears to be random since binding of one effector did not block the binding of the other. digital.library.unt.edu/ark:/67531/metadc277577/
Applications of Reductive Analytical Techniques in the Phrygian Settings of the Orgelbüchlein by J.S. Bach
This study aims to two problematic aspects of the Phrygian mode: a. the development of a harmonic pattern at the cadence that differs from that of the other modes and of the major and minor modes as well; b. the observation that the Phrygian scale inverts all of the intervallic properties of the Major scale. The result of these two observations is that when the reductive techniques of Heinrich Schenker are applied in the Phrygian repertory, melodic and harmonic properties are brought into conflict with each other. However, application of alternative models of the Ursatz developed by Lori Burns has certain benefits for demonstrating musical properties in the Phrygian repertory. digital.library.unt.edu/ark:/67531/metadc279049/
An Approach Towards the Total Synthesis of Clonostachydiol
The syntheses of the unsymmetrical 14-membered bismacrolides have been reviewed. A total synthesis of clonostachydiol, the latest to join this family, has been attempted using trimethylsilyl acetylene as the builiding block and palladium catalyzed reactions for the formation of key bonds. The alkyne groups were introduced by Stille coupling of trimethylstannylethynyltrimethylsilane with an acid chloride for one fragment and by addition of lithiotrimethylsilyl acetylene to an aldehyde for the other. Lactic acid derivatives were chosen as starting materials for both fragments, thus introducing two of the chiral centers. The remaining stereocenters were introduced using stereoselective reductions of ketones. digital.library.unt.edu/ark:/67531/metadc278800/
An Argument for the Reassessment of Stravinsky's Early Serial Compositions
Between 1952 and 1957, Igor Stravinsky surprised the world of music by gradually incorporating serialism into his style of composition. Although Stravinsky still used the neo-classical trait of making strong references to the music of earlier periods, musical analyses of this transitional period have focused on serial aspects to the exclusion of anachronistic elements. Evidence of Stravinsky's possible use of musical structures adapted from earlier times is found in his consistent use of musical figures that are closely related to the cadences of the late Medieval and Renaissance eras. By fully addressing these neo-classical traits in future analyses, music theorists will gain an additional perspective, which is helpful in understanding the music of Stravinsky's transitional period. digital.library.unt.edu/ark:/67531/metadc278325/
The Arrangement of Ezra Pound's Personae (1926) : An Interpretive Application of Editorial and Critical Theory
Pound foregrounded the importance of "shaping" poetic books through particular arrangements of individual poems by using his ideogrammic method as the crucial organizational principle for constructing Personae (1926). Critics have long understood Pound's use of the ideogrammic method in individual poems, but have so far ignored his application of it to the structuring of poetic books and sequences. Lea Baechler and A. Walton Litz, the editors of a 1990 edition of Personae (1926), however, have moved a crucial section of poems, and their rearrangement of the original text both disregards evidence of authorial intention and obscures Pound's innovative principles for arranging his shorter poems into meaningful sequences. digital.library.unt.edu/ark:/67531/metadc278644/
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. digital.library.unt.edu/ark:/67531/metadc2253/

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 and WT --34 amino acids from the N-terminus of the PyrB polypeptide. The results showed that the phosphorylation sites were located on the fragment that contained amino acid number-35 to amino acid number-112 from the N-terminus of the PyrB polypeptide. digital.library.unt.edu/ark:/67531/metadc278618/
Assessing Effects of an Environmental Education Field Science Program Fostering Responsibility at an Urban Middle School
The study investigated the ability of an extracurricular program to influence environmental responsibility of sixth and seventh graders. The Children's Environmental Attitude and Knowledge Survey (CHEAKS) was evaluated for appropriateness in assessing the worth of this particular environmental education strategy emphasizing water quality fieldwork and technology. CHEAKS is designed with psychometric reliability and validity that may be used in comparing disparate programs. Wilcoxon two sample tests were used to analyze data gathered from two student groups; one participated in an "Enviro-Mentals Club"; the other received no treatment. Analysis showed no significant change in environmental attitudes between groups, but did show significance (p <= 0.05) in environmental knowledge growth. Therefore, the investigated program had marginal success in influencing environmental responsibility. digital.library.unt.edu/ark:/67531/metadc277772/
