A Land-Use and Water-Quality History of White Rock Lake Reservoir, Dallas, Texas, Based on Paleolimnological Analyses

White Rock Lake reservoir in Dallas, Texas contains a 150-cm sediment record of silty clay that documents land-use changes since its construction in 1912. Pollen analysis corroborates historical evidence that between 1912 and 1950 the watershed was primarily agricultural. Land disturbance by plowing coupled with strong and variable spring precipitation caused large amounts of sediment to enter the lake during this period. Diatoms were not preserved at this time probably because of low productivity compared to diatom dissolution by warm, alkaline water prior to burial in the sediments. After 1956, the watershed became progressively urbanized. Erosion decreased, land stabilized, and pollen of riparian trees increased as the lake water became somewhat less turbid. By 1986 the sediment record indicates that diatom productivity had increased beyond rates of diatom destruction. Neither increased nutrients nor reduced pesticides can account for increased diatom productivity, but grain size studies imply that before 1986 diatoms were light limited by high levels of turbidity. This study documents how reservoirs may relate to land-use practices and how watershed management could extend reservoir life and improve water quality.

The Unique Challenges and Experiences of African¬-American Women Academicians at Predominantly White Institutions

This session addresses the unique challenges of African-American women academicians at predominantly white institutions. After assessing scholarly literature in this area, most research has and continues, to ignore the interrelationship between race, class and gender. This paper builds on existing literature by offering a discourse that addresses various challenges facing these women.

The Change from Red to White Meat: The Role of Technology

Since 1950, the composition of the U.S. meat diet has shifted markedly from red meats to poultry. For example, from 1970 to 1984, on a percapita basis, beef consumption has declined by 6.4 percent, while chicken and turkey consumptions have increased by 37.9, and 42.5 percent respectively (U.S. Department of Agriculture, 1985). The numerous studies of this phenomenon from the demand side (Chavas, 1983; Braschler, 1983; Nyankori and Miller, 1982; Moschini and Meilke, 1984; Wohlgenant, 1985, Thurman, 1987; Chalfant and Alston, 1988) have failed to achieve a consensus as to whether a change in taste contributed to this shift. One reason for the lack of consensus is that the very large price and quantity changes make it difficult to establish whether consumers are on a new indifference map. But there have been no comparable studies of the nature and causes of the technological change that has made these large consumption and price changes possible. A decrease in the relative price of poultry with respect to red meat is in any case a major explanation of recent shifts in meat consumption patterns. The main reason for such a decrease appears to be a higher rate of technical progress in the poultry industry than in the red meat industry. Substantial productivity gains in both the production and marketing of poultry over the last two decades appears to have been translated into lower retail prices for poultry. Although some productivity gains have taken place in the red meat industry, they have not matched the cost reductions in the poultry industry (Chavas, 1987). Thus, a consumption shift from beef to poultry could possibly be interpreted as a response to changing relative prices, the structural change having occurred in the meat industry. This would imply that, if the beef industry desires to maintain or expand its market, it should seek a decrease in the production and marketing costs of beef.

Teaching the History of Civil Rights at A Predominantly White Institution

Building on a 2003 pilgrimage to a dozen sites important in the Civil Rights Movement of the 1950's and 1960's, and conversations with movement leaders of then and now, the authors created an initiative at their 93% white campus to educate today's students about the heritage the civil rights struggle

Obstacles to Inter-Racial Understanding: Some Clinical Implications for Mental Health Practitioners in Predominantly White Institutions

in the context of predominantly white institutions. In this paper concepts such as projection, projective identification, splitting, scapegoating, superiority and denial will be employed to illustrate why racial prejudice is a deeply-rooted collective psychological disorder that affects even educated mental health practitioners. Clinicians have an ethical responsibility to demonstrate cultural sensitivity and empathy when working with minority clients, colleagues, staff and students, to examine and root out their own prejudices, and to encourage others to do the same.

The Shaping of a New Identity: Continuation of the Transformation Process of People of Color on White University College Campuses Into "White" People of Color

“Our study will show how the pyramidal structure as a permanent feature of every aspect of American society continues to function in the same manner at institutions of higher learning.”

"TEACHING FROM A CRITICAL, ANTI-RACIST PERSPECTIVE-BASED PEDAGOGY TO PREPARE WHITE STUDENTS FOR CULTURAL DIVERSITY: RESISTANCE AND CONSEQUENCES"

How are faculty of color retained once they are recruited? More importantly, how do factors such as white student resistance and negative disposition toward faculty of color impact the retention of faculty of color?
