This paper describes the depiction of Colorado animals and their environments through earthenware. Laura Newby describes the process and inspirations behind the pieces and describes each one in turn.

The duality of repulsion and attraction is present in all aspects of life, neither existing exclusive of the other. This awareness has manifested itself in the need for creating work addressing the complexity of this duality and finding a balance that relates to human experience. The purpose of his problem in lieu of thesis was to combine my concept of the attractive, present in my early graduate work, with explorations on the concept of repulsion, to heighten the visual and psychological dynamic of the whole.

This exploratory study drew from research in family art therapy assessment by Kwiatkowska (1978), Landgarten (1987), Kurinsky (1986), and Wilson (1988). The objectives of this study were to develop a theoretically consistent art therapy assessment tool for Adlerians to use in initial family therapy interviews and to evaluate its effectiveness in a field test with families of adolescents. Accounts of the families' perceptions of their AFAAT experience and the researcher's and three trained family therapists' interpretation of the six families were provided. An overview of the six families' perceptions of their AFAAT experience, their interactions, their art works, and hypotheses about indicators of adolescence as seen in their art works were also described. Although compelling anecdotal information about families of adolescents and their art work was obtained from the study, the validity and reliability of the AFAAT, as established in this study, is insufficient. Recommendations for improvements to the AFAAT and ideas for future studies to refine and utilize it more effectively concluded the study.

This research focused on discovering the most valued books in adult religious education through a survey of professors of adult religious education and in bibliographies of recent dissertations in adult religious education. Three groups of adult religious educators participated in the survey: the religious adult educators who are members of the adult sections of the Association of Professors and Researchers of Religious Education and North American Professors of Christian Education, and professors of adult religious education in Southern Baptist theological seminaries. In addition the author surveyed the adult religious education dissertation bibliographies for the period 1980-1995 to discover the most frequently cited adult religious education books. The author developed a listing of 312 adult religious education books published in English. Then a jury of three experts in the field choose seventy-seven books which they valued. From this list the three groups of professors choose books according to three criteria: textbooks they used in adult religious education courses, books they recommended as additional reading, and books they valued in the field.

Virtually disregarded in contemporary discussions of cello performance and pedagogy is the name of Luigi Silva (1903-1961). Though he did not achieve fame as a performer to the same degree as his peers Leonard Rose (1918-1984), Emanuel Feuermann (1902-1942) or Gregor Piatigorsky (1903-1976), Silva had an internationally-acclaimed performing career. Owing to his formidable technique on the instrument, he was known as the "Paganini of the cello." Through Silva's unparalleled ability to analyze technical problems in his students' playing and assist his student have populated faculties of most of the major American post-secondary schools of music and many of the principal chairs in important symphony orchestras. Of even longer-lasting significance is his enormous contribution to the literature for cello of over 100 transcriptions and scholarly editions of standard cello repertoire. By combining his own incredible artistry on the instrument and his extraordinary enthusiasm for teaching with his transcriptions of such works as the 24 Paganini Caprices, Silva helped raise the standard of cello technique to an unprecedented level and has impacted in one way or another every cellist in the twentieth century. This dissertation document describes the influences Silva's transcriptions and editions have had on cello playing and teaching in the …

Twenty-nine (Group One, June 8,1995) grass carp (Ctenopharyngodon idella) and five (Group Two, April 18, 1996) grass carp were radio-tagged to monitor movement patterns and habitat preferences on North Lake, a 335 hectare multi-use reservoir located in Irving, Texas. Overall fish mean Average Daily Movement (ADM) rates were 49.2 meters/day (during Half One, 6/8/95-11/30/95) and 5.3 meters/day (during Half Two, 12/14/95-6/6/96). Aquatic macrophtye distribution data were obtained. Radio-tagged grass carp were located in Hydrilla verticillata infested areas increasingly throughout the study, however, percent frequency of Hydrilla along 15 transects did not decrease. Radio-transmitters were equipped with temperature-sensors (10-35 Celsius range). Results indicated that radio-tagged grass carp showed no avoidance of areas of North Lake with elevated water temperatures. Radio-tagged grass carp dispersed quickly from stocking point, then moved into littoral areas infested with Hydrilla. After an initial movement period, most fish remained in a localized area.

In the leukemia case the unseparated B and T lymphocytes had a high translocation frequency even after 0.0014, respectively. After purging all clones from the data, the translocation frequencies for Bio 8 and Bio 23 were 0.00750.0014 and 0.0073 metaphases were scored for chromosomal aberrations,, specifically reciprocal translocations, using fluorescence in situ hybridization (FISH). Metaphase spreads were used from two healthy, unexposed individuals (not exposed to radiation, chemotherapy or radiotherapy) and one early B- precursor acute lymphocytic leukemia (ALL) patient (metaphase spreads from both separated T lymphocytes and unseparated B and T lymphocytes were scored). All three individuals had an abnormally high translocation frequency. The high translocation frequencies resulted from clonal expansion of specific translocated chromosomes. I show in this thesis that by purging (discounting or removing) clones from the data of unexposed individuals, one can obtain true background translocation frequencies. In two cases, Bio 8 and Bio 23, the measured translocation frequency for chromosomes 1, 2 and 4 was 0.0124 purging all of the clones from the data. This high translocation frequency may be due to a low frequency of some clones and may not be recognized. The separated T lymphocytes had a higher translocation frequency than expected.

Atmospheric iron (Fe) is thought to play an important role in cloudwater chemistry (e.g., S(IV) oxidation, oxidant production, etc.), and is also an important source of Fe to certain regions of the worlds oceans where Fe is believed to be a rate-limiting nutrient for primary productivity. This thesis focuses on understanding the chemistry, speciation and abundance of Fe in cloudwater and aerosol in the troposphere, through observations of Fe speciation in the cloudwater and aerosol samples collected over the continental United States and the Arabian Sea. Different chemical species of atmospheric Fe were measured in aerosol and cloudwater samples to help assess the role of Fe in cloudwater chemistry.

Synthetic aperture radar (SAR) has become an important tool for remote sensing of the environment. SAR is a set of digital signal processing algorithms that are used to focus the signal returned to the radar because radar systems in themselves cannot produce the high resolution images required in remote sensing applications. To reconstruct an image, several parameters must be estimated and the quality of output image depends on the degree of accuracy of these parameters. In this thesis, we derive the fundamental SAR algorithms and concentrate on the estimation of one of its critical parameters. We show that the common technique for estimating this particular parameter can sometimes lead to erroneous results and reduced quality images. We also employ time-frequency analysis techniques to examine variations in the radar signals caused by platform motion and show how these results can be used to improve output image quality.

Among the many types of organic films, covalently-attached organosulfur monolayers have attracted a great deal of attention. The authors have focused their interest on the fundamental characterization of spontaneously adsorbed organosulfur monolayers. An introductory chapter presents general aspects of monolayer preparation and characterization, followed by a few examples that illustrate the range of applications of these films. This thesis contains two papers. In the first paper, three analogous monolayer precursors are studied to determine their similarities and differences in the monolayer structure. A GC-MS analysis of products form the chemisorption process and open circuit potential measurements are used to derive possible mechanisms behind monolayer formation. The second paper focuses on monolayers formed from thioctic acid, including its characterization and application to cytochrome c electrochemistry. Although thiols and disulfides have been extensively studied as monolayer precursors, thioctic acid is particularly interesting because the disulfide functionality of this asymmetric molecule is contained in a strained five-membered ring. Given the ring strain, steric bulk and asymmetry of the molecule, the study of these monolayers lend insight into the factors important for the formation of organosulfur monolayers. This thesis concludes with a general summary and directions for future studies. 40 refs.

Pure stands of Ryegrass were in their third year of growth in the field, exposed to either ambient (355 {mu}mol mol{sup -1}), or elevated (600 {mu}mol mol{sup -1}) atmospheric CO{sub 2} concentration. A Free-Air CO{sub 2} Enrichment (FACE) system was used to maintain the elevated CO{sub 2} concentration whilst limiting experimental constraints on the field conditions. The theoretically predicted increase in the net rates of CO{sub 2} uptake per unit leaf area (A {mu}mol mol{sup -1}) as a consequence, primarily, of the suppression of photorespiration by CO{sub 2} a competitive inhibitor of RubP oxygenation by Rubisco, was observed for the Lolium perenne studied. Also observed was a general decline in leaf evapotranspiration (E) consistent with observations of increased water use efficiency of crops grown in elevated CO{sub 2}. Enhancement of leaf A in the FACE grown L. perenne ranged from 26.5 1 % to 44.95% over the course of a diurnal set of measurements. Whilst reductions in leaf E reached a maximum of 16.61% over the same diurnal course of-measurements. The increase in A was reconciled with an absence of the commonly observed decline in V{sub c}{sub max} as a measure of the maximum in vivo carboxylation capacity of the …

This study examines the waste of cotton gins as a potential alternative energy source, on account of its heat content, availability, and low emission rates. To confirm that this potential energy source meets minimum industrial fuel standards, this research has carried out an investigation of some important physical characteristics and toxic element analysis of cotton gin waste. Using cotton gin waste as fuel is an attractive solution to the problems of disposing of a surplus agricultural waste as well as supplementing fuel must meet both environmental emission standards and industrial fuel standards, the physical and chemical characteristics of cotton gin waste and its toxic element concentrations are important for its objective evaluation as a fuel. Constituent components, moisture contents, and ash contents of four separate parts of cotton gin waste were determined and evaluated closely following the American Society for Testing and Materials (ASTM) test methods. The three most toxic heavy metals, Arsenic (As), Chromium (Cr), and Lead (Pb), chosen for quantitative analysis were determined by using an inductively coupled plasma atomic emission spectrometry and a microwave oven sample digestion method.

Public concern with respect to declining traditional values, character, and family structure in the midst of increased crime, violence, and drug use have brought American education into the political arena and under intense scrutiny. The purpose of this study was to investigate whether or not differences exist in the values fostered in private schools, public choice schools and public attendance-zone schools and whether or not there are differences in the values that are identified by students as compared with teachers. The theoretical framework for the study is based upon the beliefs that values form the foundation of human behavior and that schools influence the values of societies in which they exist.

This thesis examines the portraiture of Elisabeth Vigée-Lebrun and Adélaide Labille-Guiard within the context of their time. Analysis of specific portraits in American collections is provided, along with an examination of their careers: early education, Academic Royale membership, Salon exhibitions, and the French Revolution. Discussion includes the artists' opposing stylistic heritages, as well as the influences of their patronage, the French art academy and art criticism. This study finds that Salon critics compared their paintings, but not with the intention of creating a bitter personal and professional rivalry between them as presumed by some twentieth-century art historians. This thesis concludes those critics simply addressed their opposing artistic styles and that no such rivalry existed.

This study examines the thirteenth century Artesian trouvère Adam de la Halle in the manuscript Paris, Bibliothèque Nationale f.fr 25566 as it pertains to the oral/literate model for explaining characteristics of musical traditions. The fortuitous collaboration of a single scribe with a single composer on a musical collection encompassing a cross-section of thirteenth-century styles and idioms make this repertoire uniquely appropriate to a comparison of musical oracy and literacy.

The purpose of this study is to determine the impact on student use of electronic information systems when teachers have been given instruction on their use. By providing teachers with a solid introduction to the technology, a handy reference book, and an easy-to-use evaluation tool, it is expected that they will incorporate information found on the internet into their lessons at least twice a month. In addition, teachers will allow students to access information on their own, provided computers and Internet access are available, at least once a month.

This research examines how experience and missing information affect judgments of tax return preparers. Tax return preparers may often be faced with the problem of incomplete information, and their responses to this problem may be conditioned by whether or not they recognize information is missing. Based on the Holland et al.'s cognitive theory of induction as applied to tax judgment by Marchant et al., it was hypothesized that experienced tax preparers would correctly classify more items as to their relevance to a specific tax issue than novice tax preparers. Additionally, it was hypothesized that the strength of recommendations of tax preparers who had no relevant information missing would be greater than the strength of recommendations of tax preparers who had relevant information missing and were prompted that information was missing. Lastly, it was hypothesized that prompting that relevant information was missing would have a greater effect on the strength of recommendations of tax return preparers with lesser specific experience than it would on the strength of recommendations of tax return preparers with greater specific experience. The results suggest that experienced tax preparers do recognize the relevance of information to a greater degree than novice tax preparers. There was no significant …

The problem in this study was to determine the relationship between the scores on the three parts (reading, writing, and mathematics) of the Texas Assessment of Academic Skills Test (TAAS) and the academic success of first-year students at Clarendon College, Clarendon, Texas. High school grade-point average and gender were also included in the study. The purpose of the study was to develop an equation to predict first-year college grade-point average at Clarendon College . The predictor variables were the three parts of the TAAS Test (reading, writing, and mathematics) , high school grade-point average, and gender. The equation was developed through multiple correlation/multiple regression multivariate procedures. All statistical analyses were calculated through sub-programs of the Statistical Package for the Social Sciences (SPSS). The study was limited to using only 1992/1993 Texas high school graduates who had entered Clarendon College in the fall semesters of 1992 and 1993 directly following high school graduation. A search of Clarendon College records produced 115 students from these groups who fully met all standards defined for the study. Two predictor equations were developed. One developed through a simple regression command included all five predictor variables. The second equation was produced through a stepwise procedure. This …

The Substance Abuse Subtle Screening Inventory was constructed to screen for substance abuse patterns despite non-admittance of respondents. Predictive validity studies of the SASSI are limited, and are not available for probationers. Participants were 147 male and 54 female probationers mandated to treatment. Overall differences among SASSI scales were significant for treatment compliance and outcome. Higher SASSI scales were found among those probationers who were compliant/successful. Individual scales were not significantly different, however, a trend was revealed; those respondents who scored higher tended to comply/succeed in treatment. The SASSI alone accurately classified 59.7% of respondents. In summary, the SASSI's use in predicting treatment outcome is limited and should be employed with concomitant data.

The purpose of this study was to follow the development of children with reading disabilities only, reading disabilites and ADHD, ADHD only, and a comparison group from the ages of 3 to 18. Differences were examined on the following variables: (a) Antecedent variables- Reynell Developmental Language Scales, Temperament, and Family Adversity; (b) School-age variables- behavioral and academic self-concept ratings; and (c) Psychological adjustment variables at age 18- self-reports of delinquency. Children from the reading disabled groups exhibited receptive language deficits, were from families who during the early childhood years had less resources to cope with problem situations, exhibited difficult temperamental characteristics, and had negative academic self-concepts. Distinctions were also noted between a "pervasive" and "situational" presentation of behavioral problems. During late adolescence the reading disabled groups exhibited similar levels of delinquency as their non-disabled peers. The implications of this study and directions for future research are discussed.

The worlds of Dickens's novels and of Darwin's science reveal striking similarity in spite of their involvement in different areas. The similarity comes from the fact that they shared the ethos of Victorian society: laissez-faire capitalism. In The Origin of Species, which was published on 1859, Charles Darwin theorizes that nature has evolved through the rules of natural selection, survival of the fittest, and the struggle for existence. Although his conclusion comes from the scientific evidence that was acquired from his five-year voyage, it is clear that Dawinian nature is reflected in cruel Victorian capitalism. Three novels of Charles Dickens which were published around 1859, Bleak House, Hard Times, and Our Mutual Friend, share Darwinian aspects in their fictional worlds. In Bleak House, the central image, the Court of Chancery as the background of the novel, resembles Darwinian nature which is anti-Platonic in essence. The characters in Hard Times are divided into two groups: the winners and the losers in the arena of survival. The winners survive in Coketown, and the losers disappear from the city. The rules controlling the fates of Coketown people are the same as the rules of Darwinian nature. Our Mutual Friend can be interpreted as …

The purpose of this study was to re-examine the issue of whether adult children of alcoholics experience more depression, anxiety, and lower self-esteem than do children of non-alcoholic families. This study is a replication of the study of David Dodd, entitled A Comparison of Adult Children of Alcoholic Families with Adult Children from Non-Alcoholic Families. 1990. The measures used in this study were as follows: Children of Alcoholics Screening Test, the Beck Depression Inventory, the State-Trait Anxiety Inventory, the Coopersmith Adult Self-Esteem Inventory, and a questionnaire developed by this writer designed to obtain family history regarding not only alcoholism, but other issues of family dysfunctionality as well. The subjects for this study were 231 students enrolled in the counselor education program at this university, all aged 19 or older. Of the 230 subjects, 31 were male and 199 were female. Eleven males identified themselves as children of alcoholics, as measured by the Children of Alcoholics Screening Test, and 60 females identified themselves as children of alcoholics. Thus, a total of 71 subjects in this study were identified as children of alcoholics. T-tests were conducted to see whether any differences existed between the male and female groups. No significant differences were …

Some salespeople cope with the chronic stress that accompanies sales jobs better than others. That is, while all salespeople possess some ability for coping with job stress, some coping mechanisms work better than others. Thus, it is critically important to identify the coping mechanismwhich are associated with the most positive organizational outcomes (i.e., higher performance, increased retention). Research on the coping mechanisms of salespeople is in its exploratory stage. Increased knowledge concerning how salespeople cope with chronic job stress would help researchers and managers to clarify why certain job outcomes occur instead of others (i.e., performance, retention, and burnout). This study proposes and tests a set of relationships pertaining to the dimensionality and the outcomes of salespeople's coping styles. The model identifies the antecedents of coping style and proposes three types of coping style salespeople employ to reduce job stress- emotion focused coping (EFC), problemfocused coping (PFC) and action oriented coping (AOC). It also elucidates the outcomes associated with EFC and PFC styles. The empiricalfindingssuggest that among salespeople, those who use PFC possess a more pronounced internal locus of control, perceive higher social support, and project higher continuance commitment, and higher self efficacy than those who use EFC. The findings …

A mail survey of Nigerian immigrants in Dallas, Texas, and Chicago, Illinois, was conducted during October and November 1995. Four hundred and sixty-eight Nigerian immigrant families in the two cities were selected by systematic sampling through the telephone books. Return rate was approximately 40% (187). The variables included in the study were media exposure variables, general demographics, immigration traits, U.S. demographics, Nigerian demographics, and political and cultural traits. New variables which had not been included in previous studies were also tested in this study: television talk shows, talk radio, diffuse support for the U.S. political system, authoritarianism, self-esteem, and political participation. This study employed multiple regression analysis and path analysis of the data. This study found that Nigerian immigrants have high preference for television news as their main source of political information. This finding is in consonance with previous studies. Nigerian immigrants chose ABC news stations as their number one news station for political information. Strong positive associations existed between media exposure and length of stay in the United States and interest in U.S. politics. Talk radio positively associated with interest in U.S. politics and negatively associated with length of stay in the United States. Thus, this finding likely means …
