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.

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.

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 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.

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.

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.

A Narrative Herstory of Women's Studies at the University of North Texas

Description: In the late 1960's the academic field of Women's Studies was created to give women a more equal education and a more accurate reflection of their history and impact on society. At the University of North Texas the effort to implement Women's Studies was not begun seriously until the late 1980's. This paper covers the effort to establish Women's Studies at UNT. My thesis is that this has been a grassroots effort led by professors and students who succeeded not only in establishing Women's Studies but also in changing the face and feeling of the University, creating a more positive environment for women. The bulk of the paper is made up of narrative selections drawn from oral history interviews with key individuals.

No Fairy Godmothers: Essays on Life, Love, and Feminism

Description: Heterosexual romance and marriage are institutionalized ideals in our society, set forth, in part, through the portrayal of stereotyped gender roles in fairy tales, such as Cinderella, and by the mainstream media. This thesis explores the cultural messages aimed at women, which impose the necessity of altering oneself to achieve marriage, and offers feminist viewpoints. Using the form of the personal essay, I discuss the ideals of Cinderella, Prince Charming, marriage, and Happily Ever After as unrealistic, though still prevalent, given the popularity of books like The Rules: Time-tested Secrets for Capturing the Heart of Mr. Right, and Princess Diana as Cinderella icon. Essays on my own experience of marriage and divorce supplement the cultural issues, juxtaposing the personal and political toward a new paradigm for relationships.

Status Determinants for Professional Sports and Professional Athletes

Description: The purposes of the investigation were to determine if status of professional sports and professional athletes increases as male participation increases, if perceived status of 'athlete' increases with participation in sports that contain 'male' attributes, and if gender differences are related to status indicators. Sixty-eight students were administered a status-determinants questionnaire. A one-way ANOVA (gender) and a 2 x 12 ANOVA (gender x sport) were employed to determine status ratings of sports. A 3 x 2 (increase/decrease/no change x gender) Chi square was employed to determine status of sports, perceived masculinity of males/femininity of females, and status of the athlete related to gender attributes of sports.

A Survey of Landowner Attitudes Toward the Construction of Lake Ray Roberts

Description: Documentation of social impacts resulting from the construction of Lake Ray Roberts is to be incorporated into a two year post-impoundment study. Research objectives are to: 1) locate current residences of landowners and previous landowners who were displaced; 2) determine social impacts resulting from construction of Lake Ray Roberts; 3) document degree of satisfaction with current living conditions; 4) document landowners' degree of satisfaction associated with COE negotiations; 5) document landowners' observations. Landowners were identified by telephone and sent a mail-back questionnaire. Respondents were generally happy with current residences and communities. While courtesy and sufficient information were provided by the COE, respondents would have preferred for property settlements to be more consistent and timely.
