Near-Death Experiences and the Theory of the Extraneuronal Hyperspace

Description: Abstract: It is possible and desirable to supplement the traditional neurological and metaphysical explanatory models of the near-death experience (NDE) with yet a third type of explanatory model that links the neurological and the metaphysical. I set forth the rudiments of this model, the Theory of the Extraneuronal Hyperspace, with six propositions. I then use this theory to explain three of the pressing issues within NDE scholarship: the veridicality, precognition and "fear-death experience" phenomena.

Adhesion/Diffusion Barrier Layers for Copper Integration: Carbon-Silicon Polymer Films and Tantalum Substrates

Description: 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 ...

The Afro-British Slave Narrative: The Rhetoric of Freedom in the Kairos of Abolition

Description: 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 ...

An Analysis of the Ability of an Instrument to Measure Quality of Library Service and Library Success

Description: 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.

Asleep in the Arms of God

Description: 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.

Benchmarks in American Higher Education: Selected Approaches for Distance Education Copyright and Intellectual Property Policies

Description: 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.

Cassette Systems for Creating Intergeneric Hybrid ATCases

Description: Cassette systems for creating intergeneric hybrid ATCases were constructed. An MluI restriction enzyme site was introduced at the carbamoylphosphate binding site within the pyrB genes of both Pseudomonas putida and Escherichia coli. Two hybrids, E. coli pyrB polar domain fused with P. putida pyrB equatorial domain and P. putida pyrB polar domain fused with E. coli pyrB equatorial domain, are possible. The intergeneric E. coli-P. putida hybrid pyrB gene was constructed and found to encode an active ATCase which complemented an E. coli Pyr- strain. These hybrids are useful for kinetic and expression studies of ATCase in E. coli.

Chemotactic Response of Lumbricus terrestris Coelomocytes to Larval and Adult Stages of Rhabditis pellio

Description: Experiments were performed to assess the suitability of Rhabditis pellio, a nematode found in earthworms, as a challenge organism for use in development of a biomarker assay to determine the potential of chemicals to suppress the immunocompetence of the non-specific immune system. To accomplish this goal, information on the life cycle of R. pellio was determined; including effects of incubation time and temperature on growth rates; along with information on the immune response elicited in the earthworm, Lumbricus terrestris. Immune parameters measured were coelomocyte migration toward and attachment to R. pellio larvae and adults. Preliminary background information showed that R. pellio has potential as a challenge organism for development of a biomarker assay.

Classification of Toolmark Surfaces on Zipper Teeth

Description: This study proposes the classification of the toolmark under the heads of zipper teeth as a subclass characteristic as outlined by the Association of Firearm and Toolmark Examiners (AFTE). Two separate cases in which zipper teeth were found at crime scenes prompted this study. Brass zipper teeth manufactured by YKK were taken from 20 pairs of jeans and studied using a Reichert comparison microscope at 4X power. Photographs were taken and over 750 comparisons made. It was found that the toolmarks on each side on the 20 zippers were unique and independent of all other sides. The observations made in this study indicate that classifying zipper teeth toolmarks as a subclass characteristic is valid.

Counselor Effectiveness and Correlations With Select Demographic Variables for Masters Level Counseling Students

Description: 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.

Cure Kinetics and Processing Parameters of Neat and Reinforced High Performance Epoxy Resins: Evaluation of Techniques

Description: Kinetic equation parameters for the curing reaction of a commercial glass fiber reinforced high performance epoxy prepreg composed of the tetrafunctional epoxy tetraglycidyl 4,4-diaminodiphenyl methane (TGDDM), the tetrafunctional amine curing agent 4,4’-diaminodiphenylsulfone (DDS) and an ionic initiator/accelerator, are determined by various thermal analysis techniques and the results compared. The reaction is monitored by heat generated determined by differential scanning calorimetry (DSC). The changes in physical properties indicating increasing conversion are followed by shifts in glass transition temperature determined by DSC and temperature-modulated DSC (TMDSC), thermomechanical (TMA) and dynamic mechanical (DMA) analysis and thermally stimulated depolarization (TSD). Changes in viscosity, also indicative of degree of conversion, are monitored by DMA. Thermal stability as a function of degree of cure is monitored by thermogravimetric analysis (TGA). The parameters of the general kinetic equations, including activation energy and rate constant, are explained and used to compare results of various techniques. The utilities of the kinetic descriptions are demonstrated in the construction of a useful time-temperature-transformation (TTT) diagram for rapid determination of processing parameters in the processing of prepregs.

As Darkness Falls: A Composition for Wind Ensemble

Description: As Darkness Falls is a composition that explores our interaction with several aspects of darkness through the use of musical imagery. The imagery attempts to reflect the moods, feelings, and impressions of a person as he or she interacts with darkness. The non-programmatic character of the composition allows listeners to superimpose their own experiences onto the musical tapestry in order to manifest a personal connection between the listener and the music. As Darkness Falls is a composition scored for a minimum instrumentation of piccolo, 6 flutes, 3 oboes, 3 bassoons, 9 B-flat clarinets, B-flat bass clarinet, 2 E-flat alto saxophones, B-flat tenor saxophone, E-flat baritone saxophone, 4 B-flat trumpets, 4 horns in F, 3 tenor trombones, bass trombone, 2 euphoniums, 2 tubas, timpani, and 4 percussionists. The music consists of three movements (slow-slow-fast) lasting a total of approximately seventeen minutes. The duration of each of the three movements is six minutes, four and one-half minutes, and six and one-half minutes, respectively. The document also contains an analysis of the work by the composer. The analysis explores the compositional style of the work, focusing on musical aspects within each movement that were governing parameters in the compositional process.

A Descriptive Study of Students Who Were Accepted for Admission at West Texas A&M University But Did Not Enroll

Description: 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 ...

Development of a Coaxiality Indicator

Description: The geometric dimensioning and tolerancing concept of coaxiality is often required by design engineers for balance of rotating parts and precision mating parts. In current practice, it is difficult for manufacturers to measure coaxiality quickly and inexpensively. This study examines feasibility of a manually-operated, mechanical device combined with formulae to indicate coaxiality of a test specimen. The author designs, fabricates, and tests the system for measuring coaxiality of holes machined in a steel test piece. Gage Repeatability and Reproducibility (gage R&R) and univariate analysis of variance is performed in accordance with Measurement System Analysis published by AIAG. Results indicate significant design flaws exist in the current configuration of the device; observed values vary greatly with operator technique. Suggestions for device improvements conclude the research.

Ecological Enhancement of Timber Growth: Applying Compost to Loblolly Pine Plantations

Description: This study explored the application of compost onto a small loblolly pine tree forest in northeast Texas. Its purpose was to determine if the application of various amounts of compost would provide for accelerated rates of growth for the trees. Soil parameters were also monitored. A total of 270 trees were planted and studied in a northeast Texas forest ecosystem. Compost rates of 5, 25, and 50 tons per acre with either soil or compost backfill were utilized and compared to a control without compost. Nonparametric and parametric ANOVA and Chi-Square tests were utilized. The results indicated that greater application rates retained greater moisture and higher pH levels in the soil. Compost applications also yielded a greater survival rate as well as larger tree height and diameter when compared to the control. The 25 ton/acre application backfilled in native soil achieved the greatest average in height and diameter when compared to the averages for the control plot. Greater growth differences for the 25S application can be attributed to additional nutrients coupled with a stable pH consistent with native soil acidity.

The Effects of a Tactile Prompting Device on the Requesting Behavior of a Child with Autism

Description: In the present experiment, a remote control tactile prompting device (RCT) was utilized to prompt a child with autism to recruit teacher models and play suggestions. A multiple baseline and reversal was used to assess the effects of the RCT across three play contexts. The results showed increases in the number of requests for models and suggestions as well as increases in the duration of interactive play between the child and therapist, the number of contextual statements emitted by the child, and the topography and contexts of the play behaviors emitted by the child. Findings are discussed in terms of the effectiveness and generality of the RCT and the issue of teaching a child to recruit versus teaching a child activity-specific behaviors.

The Effects of Age, Sex, and Class Stratification and the Use of Health Care Services among Older Adults in the United Kingdom

Description: As the population ages, providing health services for the growing number of older people will become an increasingly difficult problem. In countries where the health services are provided by the government, these problems are involved with complicated issues of finance and ethics. This is the case of the National Health Service, the government institution providing health care for the citizens of the United Kingdom. Knowing what social factors influence health care usage can be a link to match usage and funding. Literature has shown that health care utilization can be predicted by social factors, as well as the medical model, and from this orientation social variables were drawn from the 1994 General Household Survey. Social factors were analyzed to determine relationships that exist between certain types of health care use and these factors. Age, sex, and class, the three main factors shown in literature to affect usage, were then analyzed to determine if services are allocated on the basis of these factors or the basis of need from illness and disability. Results of the study show that of the predisposing variables, age, sex, and class, are associated with most types of health care use. From the enabling variables, both source of income and visits from friends and relatives are associated with most types of health care. Of the illness determinants, disability, limiting illness, restricted activity days and eyesight difficulty were all related to health care use. When intervening control variables were introduced, the intervening control variables of difficulty with activities of daily living and difficulty with instrumental activities of daily living had an explanatory effect on the use of home help, district nursing, consultations with a general practitioner at home, consultations with a general practitioner at a surgery or health clinic, and inpatient stays. These services were offered more according ...
