A close reading of popular discourses on women and the AIDS epidemic reveals patterns that could be described as attempts to produce and reiterate notions of normative and deviant sexuality. Prostitutes, one frequently depicted "kind" of woman, are presented as indiscriminate, polluting to men, and categorically different from "normal" women. Other women depicted in AIDS discourses are almost always HIV-positive mothers or pregnant women; these women are usually only of concern insofar as they may infect their babies. The themes of self-control, self-discipline, and personal responsibility may also be used to stigmatize women. Such discourses suggest that those who have AIDS are responsible for their own illness. They also deflect attention away from the socioeconomic contexts which may make it more difficult for some to avoid infection, away from the connections between poverty, illness, and disempowerment, and away from the systematic inequalities that characterize U.S. society.

This study sought to examine patterns of acculturation among a sample of 18 Mexican American college students and to compare them with participants' scores on a self-esteem scale, which was selected as a measure of adjustment. Mendoza's Cultural Life Style Inventory was used to assess acculturation due to its ability to provide a more precise profile of acculturation. Self-esteem was measured with the 10-item Rosenberg Self-esteem Scale. Although the findings did not indicate a statistically significant correlation between the two, the data contained in the acculturation assessments, particularly, suggested some interesting indications to the effect that while most have an overall dominant tendency of cultural shift, the tendencies exhibited in several individual dimensions more frequently tended to be cultural incorporation or cultural resistance. It was also noted that the self-esteem scores tended to be quite high.

The objective of this work is to estimate the effect of floods on the riparian vegetation communities of the Gila Box, Arizona, based on historical maps, satellite images, and GPS-referenced airborne video. The condition and extent of selected riparian vegetation communities in 1973, 1982, and 1991 are documented. Changes in riparian vegetation communities for the time period from 1973 to 1982 and from 1982 to 1991 are analyzed to assess the potential effect of floods that occurred in 1978 and 1983, respectively. The results indicate that the floods in 1978 and 1983 may have had an impact on the mesquite riparian community. The effect of floods on riparian vegetation is most apparent in the downstream portion of the Gila River. The information collected and presented in this work can be used to formulate effective management plans to the Gila Box area.

This thesis describes in-situ flow tests on bentonite borehole plugs installed in granite, as well as laboratory experiments on similar plugs. Prior to sealing, the hydraulic conductivity of the boreholes is tested. These measurements, together with core logs and borehole videologs, permit the selection of suitable seal test intervals. Standard waterwell sealing bentonite products and emplacement procedures are used for borehole sealing. Transient (short-term) and steady-state (long-term) testing determines the sealing performance of the plugs (although the premature termination of the "steady state" testing precluded full data collection). Laboratory and field experiments confirm the great difficulty of obtaining accurate performance values for bentonite plugs as installed, due to the simultaneous saturation, swelling, and consolidation effects. Conventional installation of readily available seals can provide adequate borehole seals. Bentonite plugs of this type are heterogeneous and weak. Improved testing procedures and analyses are needed if actual conductivity values are to be obtained in a reasonable testing time.
