This study examined television viewing habits and preferences of impulsive and reflective third grade and seventh grade children. Amount of television desired and reported as viewed were compared at each grade level. Impulsivity was also compared with preference for and reported exposure to each of five most commonly viewed television program types, which were situation comedy, movie, cartoon, action drama, and game show. The initial sample consisted of 46 seventh graders and 39 third graders from one middle school and two elementary schools in Pima County, Arizona. Impulsivity was measured using the Matching Familiar Figures test. Ten impulsive and ten reflective subjects were identified at each grade level. One subject furnished uninterpretable data and was dropped from the study. Subjects were asked to use copies of TV Guide magazine as viewing diaries during two one-week periods. Subjects were asked to mark in blue all programs they wished to view, and in red all programs viewed. Background data were secured from school records, and subjects completed questionnaire items regarding family size and structure, viewing circumstances, and attitudes toward television. Impulsive and reflective children were compared in overall amount of television programming selected and reportedly viewed. Differences were small, with impulsive children selecting and viewing less than reflective children at the third grade level and more than reflective children at the seventh grade level. Correlation coefficients were calculated between impulsivity and the selection and viewing of each of five popular program types. Most correlations were small. Correlations in the range of 0.35 to 0.60, however, did occur in certain cases. Selection and viewing of game shows by seventh graders showed a positive correlation with impulsivity, while selection and viewing of cartoons by third graders showed a negative correlation. A second set of correlation coefficients was calculated based on the response latency component of impulsivity. This second set reflected essentially the same relationships indicated by the first. Data from school records and questionnaire items did not enhance the interpretation of relationships between impulsivity and television use.

This study was a survey of the chronically mentally ill cases served by the Public Fiduciary of Pima County, Arizona made to determine differences between and among these cases in numbers, finances, living arrangements, and the nature of their involvement with the Public Fiduciary according to age, sex, ethnic group, and mental disorder. Information was collected on 89 chronically mentally ill cases. Summaries and statistical analyses were made of the collected information. Schizophrenia in its various forms was found to be the dominant illness. Over half of the cases lived in unsupervised settings. Almost half of the cases received supplemental security income. Three-fourths of the cases received a total income of less than 350 dollars per month. The percentage of Hispanic people in the sample was higher than in the percentage of this group in the general population of Pima county. (Abstract shortened with permission of author.)

Mining activity is suspected of contributing sulfate and total dissolved solids (TDS) to ground water downgradient of the Pima mining district. High ionic concentrations in tailing impoundments suggest that tailings-pond recharge may be a source of the contamination. Experiments indicated that sulfate is not significantly produced by inorganic sulfide oxidation in the tailings ponds. Tailings pond water chemistries were compared with historical water quality analyses in the Pima district. The U.S.G.S. computer program PHREEQE modeled saturation indices for anhydrite, calcite, fluorite, and gypsum in water chemistries throughout the study area. Well water downgradient of the mines had lower saturation indices than tailings pond water which discredits the claim that tailings-pond recharge is acquiring salts as it percolates to the aquifer. Evidence supports the opinion that tailings pond seepage is contributing to the sulfate and TDS content in ground water downgradient of the ponds.
