An Analysis of Refuse Derived Fuel as an Environmentally Acceptable Fuel Alternative for the Cement Industry

Description: Resource recovery is an attractive alternative to the waste disposal problem. The chief by-product of this process, refuse derived fuel (RDF) can be co-fired in traditional coal burning facilities. The cement industry is a potential user of RDF. This study, based on a test burn done at Texas Industries Inc. in Midlothian, Texas, demonstrated the technical, environmental, and economic feasibility of using RDF fuel in a cement kiln. Technically, the cement showed no deleterious effects when RDF was substituted for coal/natural gas at 20% by Btu content. Environmentally, acid rain gases were reduced. Economically, RDF was shown to be a cost effective fuel substitute if a resource recovery facility was erected on site.

An Analysis of the Participant Selection Process Under the Comprehensive Employment and Training Act: Texas and Louisiana

Description: Federal guidelines required prime sponsors under the Comprehensive Employment and Training Act, or CETA, to serve the "significant segments" of the eligible population. This study analyzes whether prime sponsors in Texas and Louisiana correctly identified and served those segments. This study finds that eligible ethnic groups were properly identified and were served equitably; age and gender distinctions, however, were inadequately observed in the providing of services.

The Bahá'í Principle of Religious Unity and the Challenge of Radical Pluralism

Description: The Bahá'í principle of religious unity is unique among the world's religious traditions in that its primary basis is found within its own sacred texts and not in commentaries of those texts. The Bahá'í principle affirms the existence of a common transcendent source from which the religions of the world originate and receive their inspiration. The Bahá'í writings also emphasize the process of personal transformation brought about through faith as a unifying factor in all religious traditions. The apparent differences between the world's religious traditions are explained by appealing to a perspectivist approach grounded in a process metaphysics. For this reason, I have characterized the Bahá'í view as "process perspectivism". Radical pluralism is the greatest philosophical challenge to the Bahá'í principle of religious unity. The main criticisms made by the radical pluralists are briefly examined.

Bird Bones and a Hatched Egg

Description: A fifty page manuscript of poetry and a critical introduction detailing the poet's aesthetics. Using the idea of the double-image and eroticism, the poet places her work in the category of the surreal. She describes the process of writing poetry born of fragmentary elements as a feminist emergence of agency. The manuscript is composed of four sections, each an element in the inevitable breakdown of a love relationship: meeting, love-making, birth of a child, death. Quotes from various authors of anthropological and fictional texts begin each section to reinforce thematic structure in a process of unveiling the agency of the narrator. The poems are organized as a series, beginning and ending with sequence poems.

Blood and Earth: Indivisible Territory and Terrorist Group Longevity

Description: The study of terrorism has been both broad in scope and varied in approach. Little work has been done, however, on the territorial aspects of terrorist groups. Most terrorist groups are revolutionary to one degree or another, seeking the control of a piece of territory; but for the supportive population of a terrorist group, how important is the issue of territory? Are the intangible qualities of territory more salient to a given population than other factors? Are territorially based terrorist groups more durable than their ideologically or religiously motivated cohorts? This paper aims to propose the validity of the territorial argument for the study of political terrorism.

Desorption/Diffusion of Benzene After Simulated Ground Water Remediation

Description: A study was undertaken to examine the desorption/ iffusion of benzene after simulated ground water remediation in aquifer material of differing carbon content using column experiments and comparing the results to batch experiments and adsorption empirical relationships. It was hypothesized that the organic carbon of the aquifer material will affect desorption/diffusion. Results from the column experiment indicated no significant difference in the increase benzene concentrations after remediation between aquifer materials of differing carbon content, however, a significant increase in benzene concentration was observed for all aquifer material. Fair agreement of retardation factors was observed between empirical relationships and batch and column experiments. However, the desorption phase of the batch experiment showed hysteresis and seemed to differ from the column experiment.

Dichotomy in American Western Mythology

Description: The fundamental dichotomy between savage and civilized man is examined within the archetypal Western myth of American culture. The roots of the dichotomy are explored through images produced between 1888 and 1909 by artists Frederic Remington and Charles Russell. Four John Ford films are then used as a basis for the "dichotomous archetype" approach to understanding Western myth in film. Next, twenty-nine "historical" and "contemporary" Western movies are discussed chronologically, from The Virginian (1929) to Dances with Wolves (1990), in terms of the savage/civilized schema as it is personified by the roles of archetypal characters. The conclusion proposes a potential resolution of the savage/civilized conflict through an ecumenical mythology that recognizes a universal reverence for nature.

The Effects of Pulp and Paper Mill Wastewaters on Phytoplankton Primary Productivity in the Red River, Louisiana

Description: Responses of phytoplankton productivity in the Red River to unbleached pulp and paper mill wastewaters were monitored using in situ ^14C incubation. Preoperational studies, conducted prior to the discharge of mill wastewaters varied seasonally, but revealed similar productivity trends when compared with postoperational studies, conducted after mill discharges began entering the Red River. Carbon assimilation rates measured downstream of mill discharge were generally greater than upstream levels in both preoperational and postoperational studies. Selected physical, chemical, and biological parameters varied seasonally, but showed similar upstream-downstream values and preoperational-postoperational values. Total Organic Carbon (TOC), Dissolved Organic Carbon (DOC), and Biochemical Oxygen Demand (BOD_5) were positively correlated with postoperational productivity rates. Apparent color was negatively correlated with productivity rates.

Effects of Suspended Solids on Bioavailability of Chemicals to Daphnia magna and Pimephales promelas

Description: Three suspended solids types containing a range of physicochemical characteristics were used to determine the effect of suspended solids on the bioavailability of acenaphthene, 1,2,4,5-tetrachlorobenzene, zinc, and chlordane to Daphnia magna and Pimephales promelas. Generally, the bioavailability of zinc and chlordane decreased due to interactions with all suspended solids types while bioavailability of acenaphthene and 1,2,4,5-tetrachlorobenzene were not clearly reduced. Partition coefficients and slope of dose-response curves related chemical characteristics and organism sensitivity, respectively, to experimentally determined results. It is believed that the biologically available form of these chemicals to Daphnia magna and Pimephales promelas resides in the aqueous phase.

The Emergence of the Individual in Eleventh and Twelfth Century Europe: Cistercians to Cowboys

Description: The purpose and scope of this paper is to discuss the emergence of the individual in the eleventh and twelfth centuries in light of the societal changes occurring at the time, and to establish the fact that this beginning of individualism can be seen particularly in the arts of the time. The evidence presented gives rise to the supposition that the society of the eleventh and twelfth centuries can be defined as humanistic, given that humanism implies a concern with and a concentration upon life on earth as opposed to life in heaven.

Ephippia Production, Activation, and Use of Ex-Ephippio Neonates of Ceriodaphnia Dubia as Toxicity Test Organisms

Description: Ceriodaphnia dubia is widely used as a test organism in monitoring water quality. At the present time, cultures must be continuously maintained in the laboratory. In an attempt to avoid continuous culture and maintenance, the hatching of ephippial eggs of C. dubia would provide test organisms when needed. In order to determine the parameters required for maximum hatching, approximately ninety-four thousand ephippia were exposed to a variety of conditions ranging from light and temperature regimes to drying and freezing. A low hatching yield occurred which is believed to be caused by diminished ephippia viability and/or fertility. To evaluate factors influencing the viability and fertility rate, stains of embryos were examined as were male to female ratios and mating experiments.

Excuses for the Universe

Description: We create fictions--personal and literary--to cope with fear, and it is our choice whether or not these inventions affirm life. This collection presents many ways of "making excuses for the universe," both from a personal standpoint and also by using the voices and visions of created characters. The collection contains a section of family poems and three sets of character poems: Beverly and Nanci, Strange Mary, and Blue Donna. Following each section are two related poems for transition or amplification. The poems show a progressive change in writing techniques, especially experimentation with sound, as well as pursuing the central theme that perception is a desirable goal, well worth the price.

The Geologic and Archaeological History of the Dickie Carr Site 41PR26

Description: This thesis is an analysis and synthesis of the geologic and archaeological history of the Dickie Carr site, 41PR26, on Mill Creek in north central Texas. Included are analyses of the stratigraphy, sedimentary environments, and soils of the locality. A regional comparison is made with respect to the Late Quaternary geology of the upper Trinity River basin, Texas to interpret the geologic data. Two stratigraphic units were identified that record the Pleistocene-Holocene transition. The buried lower unit is comprised of terrace, floodplain, and channel deposits with extensive pedogenesis. The unit is Late Pleistocene in age and contains the remains of Mammuthus columbi. The upper stratigraphic unit is comprised of terrace and floodplain sediments with well-expressed pedogenesis. The unit is Early Holocene in age with Late Paleoindian and Late Archaic occupations. The archaeological components are compared and contrasted with documented sites from the Elm and East Forks of the Trinity River. The occupations are examined in a geoarchaeological context. The Late Paleoindian occupation is post-depositional and located in terrace deposits. The Late Archaic occupation is syndepositional and located in floodplain deposits.

A Gobber Tooth, A Hairy Lip, A Squint Eye: Concepts of the Witch and the Body in Early Modern Europe

Description: This thesis discusses early modern European perceptions of body and soul in association with the increasing stringency of civilized behaviour and state formation in an effort to provide motivation for the increased severity of the witch hunts of that time. Both secondary and primary sources have been used, in particular the contemporary demonologies by such authors as Bodin, and Kramer and Sprenger. The thesis is divided into five chapters, including an Introduction and Conclusion. The body of the thesis focuses on religious, scientific, and secular beliefs (Ch. 2), appearance and characteristics of witches (Ch. 3), and the activities and behaviours/actions of witches, (Ch. 4). This study concentrates on the similarities found across Europe, and, as the majority of witches persecuted were female, my thesis emphasizes women as victims of the witch hunts.

The Implications of National Culture on American Knowledge Work Teams: A Model of a Collaborative Corporate Culture to Support Team Functioning

Description: In order to remain competitive, many American businesses implement team-based work strategies. In many cases, however, teams fail in American organizations, which may be in part due to a conflict between American culture and the cooperative environment necessary for teams to function effectively. By comparing the literature regarding American culture, challenges faced by teams, and then corporate culture, it becomes evident that there are aspects of American culture that pose challenges but also that an appropriate corporate culture can mediate some areas of incompatibility. A collaborative corporate culture can induce cooperation among employees without asking employees to work in a manner that is counterintuitive, thus gaining the benefits of teams.

Improving Scientific Learning and Supporting Civic Engagement for Undergraduate Non-science Majors

Description: In prior research focusing on teaching and learning science, a definitive trend toward a new approach for undergraduate non-major science courses has emerged. Instruction should be refocused from information-transfer to giving students experiences that allow them to explore and engage in their new knowledge and find ways to integrate it into their everyday lives. One technique is to focus class material on real issues of interest and relevance. Course development that allows for civic engagement and self discovery connects learning to the lives of students and their communities. This study used a quasi-experimental design to see if students who engaged in their learning had improved learning gains, increased motivation, and ability to relate it to their lives. The results showed that students were more motivated to connect the subject to their lives when they engaged through civic engagement projects. Techniques used in this research can be used in the future to develop science courses that focus on the needs of 21st century learners.

Inflation in Venezuela: The Case for No Single Cause

Description: The study was designed to examine the causal relationship between the Venezuelan inflation and the monetarist variables--money supply--and the structuralist variables-- exchange rate and balance of payments. The data (1964-1982) was gathered from the International Financial Statistic Yearbook, 1983 and the Statistical Yearbook, 1974, 1982. Chapter I is an introduction to the research problem. Chapter II does a review of the related literature. Chapter III deals with the methods and procedures for treating the data. Chapter IV presents an statistical analysis of the data. And, Chapter V contains a summary of the study and its findings, conclusions and recommendations. The study only found a significant relationship between inflation and the monetarist variables money supply and GNP, though supporting the monetarist theory. A similar investigation is suggested, but selecting a longer time period, other.variables, and more refined methodologies and analysis.

Measuring the Effects of the TYC Gainesville Resocialization Program on Juvenile Offender Resiliency Levels

Description: An analysis of the effects of resocialization programming on juvenile offender resiliency levels was conducted with 220 juveniles committed to a maximum security facility. Data were examined on the subjects' age, race/ethnicity, length of time at the facility, level of resocialization, and resiliency score. The resocialization programming contains cognitive and social components that would be instrumental in augmenting juvenile offender resiliency levels. Analysis of the variables did not show a significant increase in juvenile offender resiliency levels. The results did display that students who were at the facility longer and who were in the older age groups had higher levels of resocialization.

Modest Musorgsky's Early Songs: Uncommon Lyricisms Within a Simple Framework

Description: Modest Musorgsky is considered a composer of masterful vocal, symphonic, and piano works. His songs and song cycles distinguish themselves as evocative of the broad spectrum of Russian experience. However, Musorgsky's early songs have not received as much attention as his larger works, such as Boris Godunov or Pictures at an Exhibition. Musorgsky's early songs, from 1857-1867, show the composer's affinity for lyrical expression, be it brightly melodious, impassioned, or within a comical or satirical vein. He portrays Russian life through a mixture of different genres such as the Russian romance, the ballad, the operatic aria, and also vaudeville. This study focuses on Musorgsky's choice of texts, his penning of several of them, and the way he incorporates them within each song.

Multiple Regression Equations to Estimate Mean Nutrient Concentrations in Streams of North Central Texas from Landsat Derived Land Use

Description: Nutrients are of critical concern in water quality assessment. The development of empirical models to estimate mean nutrient concentrations, based on satellite derived land use, could aid water resource managers. Models using land use acreages outperformed those using percentages, and discrete urban land uses were superior to lumped urban. Regressions of the combinations of two, three and four of the eight possible land use variables were investigated. Sensitivity analyses, with one stream deleted each series, identified robust combinations of variables at each level. Although uncertainty exists regarding the final regression coefficients, five of the six actual measured nitrate and total phosphorus mean concentrations were within the 95 percent confidence limits.
