Sediment Bound Trace Metals in the White Rock Creek Watershed, Dallas and Collin Counties (open access)

Sediment Bound Trace Metals in the White Rock Creek Watershed, Dallas and Collin Counties

Areas were sampled in the White Rock Creek Watershed to examine sediment bound trace metal distributions and sorption relationships. A Kruskal-Wallis AOV found significant among area differences for most metals, and SNK-like multiple comparisons were used to group these areas. Kruskal-Wallis AOVs similarly found among area differences for sediment components that bind trace metals (Fe and Mn oxides and organic carbon) and physicochemical conditions that influence metal sorption (particle size and pH). Multiple correlation found numerous relationships among trace metals, sediment components, and physicochemical conditions. Statistical relationships indicate that metal partitioning to various sorption factors is metal specific. White Rock Creek Watershed trace metal concentrations are comparable to those in many urban watersheds.

Implementing Municipal Water Conservation Policy: Goals, Practices and the Case of Texas (open access)

Implementing Municipal Water Conservation Policy: Goals, Practices and the Case of Texas

This study examines whether water conservation is actually being incorporated into municipal water management practices. The development of a conservation policy from a general goal declaration to specific programmatic practices is reviewed for a Texas state water agency, the Texas Water Development Board. From January 1986 through September 1989, 102 political units in Texas applied to the Board for water-related loan funds and thus were required to implement municipal water conservation plans. Two aspects of this conversation policy are assessed: one, the Board's procedural arrangements for the development and review of water conservation plans, and two, the conservation plans of each political unit. It is concluded that Texas state water managers, and local manager also, have yet to incorporate conservation as a significant planning tool for the achievement of water management goals.

An Analysis of Refuse Derived Fuel as an Environmentally Acceptable Fuel Alternative for the Cement Industry (open access)

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

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.

Dichotomy in American Western Mythology (open access)

Dichotomy in American Western Mythology

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.

A Narrative Herstory of Women's Studies at the University of North Texas (open access)

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

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.

The Denton Mare (open access)

The Denton Mare

Some men are born to greatness, others to great tragedy. This novel is a fictional account of one of those men: the notorious Texas outlaw, Sam Bass. Set in the Old West of the 1870s, the story primarily concerns itself with events in the train robber's life from the time he owned and raced the Denton Mare to the now famous shoot-out in Round Rock, Texas. It is a story of crime and betrayal told through the eyes of Bass and one of his close confederates, Jim Murphy.
