- 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.
- 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.
- An Algorithm for the PLA Equivalence Problem
- The Programmable Logic Array (PLA) has been widely used in the design of VLSI circuits and systems because of its regularity, flexibility, and simplicity. The equivalence problem is typically to verify that the final description of a circuit is functionally equivalent to its initial description. Verifying the functional equivalence of two descriptions is equivalent to proving their logical equivalence. This problem of pure logic is essential to circuit design. The most widely used technique to solve the problem is based on Binary Decision Diagram or BDD, proposed by Bryant in 1986. Unfortunately, BDD requires too much time and space to represent moderately large circuits for equivalence testing. We design and implement a new algorithm called the Cover-Merge Algorithm for the equivalence problem based on a divide-and-conquer strategy using the concept of cover and a derivational method. We prove that the algorithm is sound and complete. Because of the NP-completeness of the problem, we emphasize simplifications to reduce the search space or to avoid redundant computations. Simplification techniques are incorporated into the algorithm as an essential part to speed up the the derivation process. Two different sets of heuristics are developed for two opposite goals: one for the proof of equivalence and the other for its disproof. Experiments on a large scale of data have shown that big speed-ups can be achieved by prioritizing the heuristics and by choosing the most favorable one at each iteration of the Algorithm. Results are compared with those for BDD on standard benchmark problems as well as on random PLAs to perform an unbiased way of testing algorithms. It has been shown that the Cover-Merge Algorithm outperforms BDD in nearly all problem instances in terms of time and space. The algorithm has demonstrated fairly stabilized and practical performances especially for big PLAs under a wide …

- 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.
- 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.
- 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.
- 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.
- Artists' Books: An Investigation Into Another Genre of Artistic Expression
- For centuries, books have been a traditional way to display prints. Contemporary artists' books have become more than simply a method of displaying prints and have, in fact, become a relevant medium for artistic expression. It has been important to my work that each of my artist's books have functioned as a unified whole, all parts of complementing each other and strengthening the overall concept.
- Assessing Regional Gully Erosion Risk: A Remote Sensing and Geographic Information Systems Approach
- Gully erosion has been established as a major source of sediment pollution in the upper Trinity River watershed in north-central Texas. This fact, along with a lack of models appropriate for a large-area gully erosion analysis established a need for a gully erosion study in the upper Trinity basin. This thesis project attempted to address this need by deriving an index indicative of gully erosion risk using remote sensing and geographic information systems (GIS) methodology. In context of previous field studies, the coarse spatial resolution of the input GIS data layers presented a challenge to prediction of gully prone areas. However, the remote sensing/GIS approach was found to provide useful reconnaissance information on gully risk over large areas.
- Assessing the Effects of a Municipal Wastewater Treatment Plant Effluent on Zooplankton, Phytoplankton and Corbicula Flumina in a Constructed Wetland

- An Assessment of Learning Outcomes of Students Taught a Competency-Based Computer Course in an Electronically-Expanded Classroom
- This study sought to determine whether there was a difference in subject matter knowledge as measured by a pretest and posttest, a difference in final course grade as a numeric score, and a difference in attitudes toward computers between students in a competency-based ("hands-on") computer applications course taught in an electronically-expanded classroom compared to students taught in a traditional classroom setting. In addition, students taught in the electronically-expanded classroom completed a questionnaire assessing attitudes toward the presentation method. Another purpose of this study was to evaluate the feasibility of applying distance education techniques to teach what was, in essence, an on-campus course. The vehicle for this investigation was an electronically-expanded classroom. The electronically-expanded classroom utilized distance education technology (video, audio, and computer networking) to connect two classrooms in the one building. Students in these two classrooms were the treatment group. Students taking the course in a traditional setting functioned as the comparison group. A total of 109 participants completed the study. Results of the study revealed no significant difference in scores on the subject matter posttest, the final course grade as a numeric score, and attitudes towards computers posttest between students taught the course in an electronically-expanded classroom and students taught the course in the traditional classroom. Results of the survey to measure satisfaction with the presentation method revealed that students in the receive room were slightly more satisfied than students in the send room with the presentation method, but the difference was not significant. The survey indicated that participants in the study were sensitive to technical problems, especially audio-related difficulties. While participants noted some dissatisfaction with audio quality, it had no apparent effect on learning outcomes and attitudes for this study. The study concluded that students taking a course in an electronically-expanded classroom have learning outcomes and attitudes toward …
- An Assessment of Storm Water Toxicity from the Dallas/Fort Worth Metroplex and Denton, Texas
- With the advent of national storm water regulations, municipalities with populations greater than 100,000 are required to obtain National Pollutant Discharge Elimination System Permits (NPDES) for storm water discharges. In addition to the sampling required for the permit process, the City of Fort Worth contracted with the University of North Texas' Institute of Applied Sciences to conduct acute toxicity testing using Pimephales prcmelas and Ceriodaphnia dubia on storm water samples received from the Dallas/Fort Worth Metroplex. A Toxicity Identification Evaluation (TIE) was performed on four samples that exhibited acute toxicity to C. dubia. High levels of metals as well as diazinon were some of the probable toxicants found.
- Attention and Information Processing Variables in Hypothetically Psychosis-Prone College Students
- Considering the explanations of schizophrenia that presume schizophrenia spectrum disorders (e.g., schizotypal personality disorder, schizoaffective disorder, etc.) to be genetically related to schizophrenia, the purpose of this study was to investigate the attention and information processing abilities of individuals who have been identified as schizotypal or psychosis-prone (i.e., schizophrenia spectrum functioning in individuals who do not have schizophrenia). Research indicates that persons identified as psychosis-prone may show attention and information processing deficits similar to individuals with schizophrenia. The identification and description of individuals who later decompensate into schizophrenia would advance the understanding of schizophrenia and its causes. The Chapman's PER-MAG scale (Perceptual Aberration-Magical Ideation) was used to identify 35 hypothetically psychosis-prone college students (schizotypy group) and 42 normal college students (nonschizotypy group) out of the 806 volunteer subjects. Their attention and information processing abilities were measured by COGLAB (a multiparadigmatic cognitive test battery that represents a continuum of cognitive functions, from preattentional to attentional, to conceptual). Their social adjustment was measured by the Premorbid Adjustment Scale (PAS). The hypotheses of the study were that the hypothetically psychosis-prone subjects would perform poorer than controls on COGLAB measures and that COGLAB measures of a more molar nature would better predict social adjustment than would the more molecular tasks. The results of the study did not support the hypotheses as there were no significant differences between the schizotypy group and the nonschizotypy group and the measures of a more molar nature did not better predict social adjustment. Further research might consider increasing the sample size, applying more stringent cut-off criteria for the schizotypy group, and verifying the validity of using PER-MAG, COGLAB, and PAS with this population. Further research also needs to clarify the ways in which those identified as psychosis-prone process information like (or unlike) nonschizotypes and how their current social functioning …
- Attributional Style as a Predictor of Academic Success for Students with Learning Disabilities and Attention Deficit Disorder in Postsecondary Education
- Thirty one students with learning disabilities (LD) and/or with Attention Deficit Hyperactivity Disorder (ADHD) completed a combined Academic Attributional Style and Coping with Academic Failures Questionnaire. The reformulated learned helplessness model (Abramson, Seligman, & Teasdale, 1978) predicted that students with negative attributional styles (i.e., internal-stable-global attributions) experienced motivational, cognitive, and emotional deficits. The present study examined college achievement (grade point average) of students with LD and/or ADHD. The Prediction that students with LD and/or ADHD with negative attributional styles would achieve less academic success than comparable students with positive attributional styles (i.e., extenal-unstable-specific attributions) was supported by the research results.
- Autographs 1928 : Four Songs for Soprano and Chamber Ensemble
- Autographs 1928: Four Songs for Soprano and Chamber Ensemble is a composition of approximately 16 minutes' duration and is scored for mezzo-soprano, flute, oboe, clarinet, horn in F, viola, violoncello, one keyboardist (piano and celesta), and two percussionists (marimba, xylophone, chimes, timpani, bass drum, temple blocks, triangle, and slapstick). The work consists of four songs and four readings with texts from Walls's maternal grandmother's autograph book. The composition opens with a reading and alternates between readings and songs. The music is intended to reflect the playful, tender and humorous nature of the lyrics.
- Benjamin West's St. Paul Shaking the Viper from his Hand After the Shipwreck: Altarpiece of 1789 and Designs for Other Decorative Works in the Chapel of St. Peter and St. Paul, The Royal Naval College, London
- This thesis analyzes Benjamin West's altarpiece St. Paul Shaking the Viper from His Hand After the Shipwreck and his designs for thirty-three related artworks in the Royal Naval College Chapel, Greenwich, England, as a synthesis of the major influences in his life and as an example of both traditional and innovative themes in his artistic style of the late eighteenth century. This study examines West's life, the Greenwich Chapel history, altarpiece and decorative scheme, and concludes that the designs are an example of West's stylistic flexibility and are related thematically to his Windsor Royal Chapel commission.
- Biodegradation of Certain Petroleum Product Contaminants in Soil and Water By Selected Bacteria
- Soil contamination by gasoline underground storage tanks is a critical environmental problem. The results herein show that in situ bioremediation using indigenous soil microorganisms is the method of choice. Five sites were selected for bioremediation based on the levels of benzene, toluene, ethylbenzene and xylene and the amount of total petroleum hydrocarbons in the soil. Bacteria capable of degrading these contaminants were selected from the contaminated sites and grown in 1,200 I mass cultures. These were added to the soil together with nutrients, water and air via PVC pipes.
- Biological and Toxicological Responses Resulting from Dechlorination of a Major Municipal Wastewater Treatment Plant Discharge to the Trinity River
- Federal regulations such as the Clean Water Act (P.L. 92-500), and its amendments, direct the Environment Protection Agency (EPA) to implement programs to control the releases of conventional pollutants and toxics into the waterways of the United States. The EPA began requiring treatment plants to conduct toxicity tests (biomonitoring) of their effluent discharges. To control toxicity caused by chlorination of wastewater discharges, the EPA also began requiring some treatment facilities to dechlorinate their wastewater before discharging. This research was funded by the EPA to document the changes that occurred in the Trinity River from the dechlorination of the effluent from Ft. Worth's Village Creek municipal wastewater treatment plant. The study occurred over a two year period beginning in August 1990. A wide variety of biological field assessments and toxicological assays were used to measure various responses. Seven river stations, covering approximately twenty river miles, and the treatment plant effluent were assessed. Two of the river stations were upstream from the treatment plant and used as reference sites. The remaining five river stations were downstream from the treatment plant, spread out over seventeen river miles. The study evaluated the impact of chlorination prior to dechlorination, which served as a baseline. Responses determined during dechlorination were compared to the baseline data. An overall improvement in species richness and diversity was seen at those river stations which had previously been adversely impacted by chlorine. Aquatic toxicity tests, such as those required to be used by dischargers, were conducted during this study. Periodic toxicity was observed with these tests in the effluent and river samples after dechlorination was initiated. Those tests, along with in situ toxicity assays, proved to be good predictors of biological community responses.
- Biopsychosocial Factors Related to Health among Older Women
- Older adults are more vulnerable to the ill effects of life stress due to physiological changes associated with aging that result in decreased immunocompetence. Stressors interacting with an aging immune system may produce further declines in health. Variables shown to modulate the effect of stressors on neuroendocrine and immune function and health include social support, personality, coping style, and health locus of control. A comprehensive model is proposed that includes: life stressors, social resources, psychological resources, interaction between stressors and social resources, neuroendocrine and immune function, and symptomatology. This model was evaluated using structured equation modeling. Participants were 97 active, community dwelling, older women, ranging in age from 60 to 93 years.
- Black Nationalism Reinterpreted
- Black nationalism responded to America's failure to examine the effects of slavery's legacy. Its aims represent those issues that were either unsupported by or in opposition to the goals of the civil rights leadership. In particular, the civil rights movement dismissed any claims that the history of slavery had a lasting effect on African-Americans. This conflict developed because of mainstream America's inability to realize that the black community is not monolithic and African-Americans were differentially affected by slavery's legacy. It is those blacks who are most affected by the culture of poverty created by America's history of slavery who make up today's inner-city populations. Despite successes by the civil rights movement, problems within lower-class black communities continue because the issues of the black underclass have not yet been fully addressed.

- Cell-Free Recovery and Isotopic Identification of Cyanide Degrading Enzymes from Pseudomonas Fluorescens
- Cell-free extracts from Pseudomonas fluorescens NCIMB 11764 catalyzed the degradation of cyanide into products that included C02, formic acid, formamide and ammonia. Cyanide-degrading activity was localized to cytosolic cell fractions and was observed at substrate concentrations as high as 100 mM. Two cyanide degrading activities were identified by: (i) the determination of reaction products stoichiometries, (ii) requirements for NADH and oxygen, and (iii) kinetic analysis. The first activity produced CO2 and NH3 as reaction products, was dependent on oxygen and NADH for activity, and displayed an apparent Km for cyanide of 1.2 mM. The second activity generated formic acid (and NH3) pfus formamide as reaction products, was oxygen independent, and had an apparent Km of 12 mM for cyanide. The first enzymatic activity was identified as cyanide oxygenase whereas the second activity consists of two enzymes, a cyanide nitrilase (dihydratase) and putative cyanide hydratase. In addition to these enzymes, cyanide-grown cells were also induced for formate dehydrogenase (FDH), providing a means of recycling NADH utilized by cyanide oxygenase.
- Characterization of Tolerance and Cross-tolerance between Noncompetitive N-methyl-D-aspartate (NMDA) Antagonists in Rats Trained to Self-administer Ketamine
- Ketamine and phencyclidine (PCP) are noncompetitive antagonists of the N-methyl-D-aspartate (NMDA) type of ligand-gated glutamate receptors. Both agents have high abuse liability, and may produce dependence. Tolerance to the reinforcing effects of drugs of abuse is widely regarded as a key component of the dependence process. Therefore, the present study was conducted to examine whether tolerance develops to the reinforcing effects of ketamine, and whether PCP and dizocilpine, a noncompetitive NMDA antagonist with negligible abuse liability, produce cross-tolerance to the reinforcing effects of ketamine. Further, identification of the neural mechanisms that underlie tolerance to the reinforcing effects of drugs may yield information regarding drug dependence.

- Chronically Ill Children: Maternal Stress and Psychological Symptomatology
- This study used a parenting stress and coping model to identify predictors of symptomatology for 13 8 mothers of medically compromised children. This model proposed that: child characteristics (severity of the chronic illness and child related parenting stressors); parent characteristics (self-esteem, sense of competence, and parents' perceived stress/distress); and environmental characteristics (social support, general life stressor events, and demographic variables) contribute to psychological symptomatology for these mothers. Multiple regression analysis found a relationship between general life stressor events, severity of the children's chronic conditions, lower satisfaction with social support, lower self-esteem, and younger mothers' ages and greater symptomatology. Trends toward significance were found for more parenting stress and lower parenting sense of competence predicting greater symptomatology. Predicted relationships between family socioeconomic status and parenting daily hassles and symptomatology were not supported.
- Climate Change 1995: IPCC Second Assessment Report
- The Intergovernmental Panel on Climate Change (IPCC) completed its Second Assessment Report in December 1995. The major conclusions are that greenhouse gas concentrations are increasing, the global climate has been changing, and will likely continue to change, probably due to human influence.

- In this USGRP Seminar, Dr. Epstein discusses the implications of climate change and the emergence of diseases and viruses such as the hantavirus, dengue fever, ebola, cholera, malaria, and eastern equine encephalitis. These signals of global change can be costly to health, commerce, tourism, and transportation.
- Climate Change: State of Knowledge
- This brief report describes that the Earth's climate is predicted to change because human activities are altering the chemical composition of the atmosphere. The buildup of greenhouse gases-primarily carbon dioxide, methane, nitrous oxide and chlorofluorocarbons-is changing the radiation balance of the planet. The basic heat-trapping property of these greenhouse gases is essentially undisputed. However, there is considerable scientific uncertainty about exactly how and when the Earth's climate will respond to enhanced greenhouse gases. The direct effects of climate change will include changes in temperature, precipitation, soil moisture, and sea level. Such changes could have adverse effects on ecological systems, human health, and socio-economic sectors.
- Climate Change: The Evidence Mounts Up
- This article was published in Nature and summarized the presentations of a six-day symposium held 3-8 July 1995 on Climate Variability and Forcing over the past mellennium. Our present climate is unusually warm, and the pattern of warming over the past century strongly suggests an anthropogenic influence from greenhouse gas and sulphate aerosols. That was the message emerging from a week-long symposium examining climate variability over the past 1,000 years, which brought together results from a growing array of observational techniques, analyses of natural records and model results.
