Degradation of Phenolic Acids by Azotobacter Species Isolated from Sorghum Fields

Description: Sorghum plants excrete phenolic acids which reduce subsequent crop yields. These acids accumulate in field soil by combining with soil and clay particles to form stable complexes which remain until degraded by bacterial metabolism. The amount of phenolic acids in soil samples were obtained by gas chromatography measurements, while Azotobacter populations were obtained by plate counts in 40 sorghum field samples from Denton County, Texas. One can conclude that increasing the Azotobacter population in the soil increased the degradation rate of phenolic acids proportionally. It is proposed that seed inoculation will introduce selected strains of Azotobacter into the soil. The presence of Azotobacter should increase crop size in subsequent plantings.

An Evaluation of the Denton County Safety Education Program in Denton, Texas

Description: The purpose of this study was to assess the effectiveness of the Denton County Safety Education Program. Subjects were 117 driving-while-intoxicated offenders who completed this alcohol reeducation program between June 1975 to June 1976. Questionnaires were used as evaluative measures. Data were analyzed in three steps: 1) two two-way ANOVAs with one repeated measure; 2) two Pearson product moment correlations; and 3) a Fisher's Z test. Conclusions of the investigation were that (1) both problem and non-problem drinkers benefited from the program; (2) change of attitude was an important factor in reducing recidivism; and (3) the program was successful in meeting its goals as a means of influencing drinking and driving behavior.

Oral Interpretation as a Catalyst for Social Awareness Ann's Haven: Hospice of Denton County

Description: This oral interpretation thesis studies the use of oral interpretation in social contexts. The context chosen was the Hospice movement, which deals with assisting terminally ill persons and their families through the stages of death and bereavement. A readers theatre script was compiled for "Ann's Haven: Hospice of Denton County," which was selected for the locus of this thesis. The script was presented to various civic groups for the purpose of informing the public and eliciting support for Ann's Haven. It was found that oral interpretation is a viable rhetorical tool and is well liked by audiences as a means of public enlightenment.
