The factors involved in calculating Standard Visual Range (SVR) are discussed, and a comparison is made between the visibility reported by airport observers and the photographic slide/ optical densitometer method of calculating SVR. Using slides of Houston, Texas, from the fall and winter of 1988-89, it was found that the altitude at which the contrast measurements are made significantly affects the SVR. Also an index for predicting high and low humidity was developed using the blue/red ratio of the log exposure of the sky, and sun/shade target condition.

Previous scholarship on labor rhetoric has concentrated on the impact of declining union membership and contemporary activist strategies on the part of unions. The press release is a common form of communication that organized labor employs in order to reach its publics. This study explores the press releases of the Texas State AFL-CIO to determine to what extent this level of labor discourse meets the criteria of a rhetorical genre. This study employs the methodology for generic criticism laid out by Foss for identifying genres. The study concludes that a genre of labor rhetoric exists and that the genre was used extensively to promote the Texas State AFL-CIO as a socially-conscious and politically motivated organization.

This thesis discusses Mexican immigration into Texas, and the communities in which the immigrants settled. The focus is on Dallas, with particular emphasis placed upon the women of Little Mexico, a specific barrio there. Sources include interviews with the subjects and their descendants, newspaper articles, journals, unpublished theses about Little Mexico, and books.

The incidence of both childhood sexual abuse and eating disorders is rising. A study of 422 undergraduate college females was undertaken using self report format to determine the incidence of childhood sexual abuse and eating disorders in a college population, and to determine the relationship between the two. In all, 57% of the women surveyed reported experiencing some form of sexual contact before the age of 14. Using the EDI-2 to assess risk of eating disorder development, 42% of these formerly abused women were found to be at risk for the development of an eating disorder. This was not found to be statistically different from the risk of eating disorder development experienced by the nonabused females in this population. However, there were differences found on the dimensions of Interpersonal Distrust, Interoceptive Awareness and Ineffectiveness, indicating that two of the major issues in eating disorder development for the abused women are trust both of themselves and of others, and self-esteem.

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.

The work traces the early history of the Texas State Department of Highways. Beginning with the first efforts to create a department, the study focuses on the period between 1917 and 1923. Much attention goes to the legislative background of the early actions of the department. Subsequently, the work examines various statistical measures of the department's performance. This includes comparisons between Texas and nearby states, and the national highs, lows, and averages. Concluding the study is an examination of the department's immediate goals and long range plans in the years after 1923. The general conclusion of the study is that the department played a useful role in the development of state roads in Texas.
