Responses of 111 doctoral clinical psychology students to Garfield and Kurtz' (1973) Testing Attitude Scale were subjected to a 2 x 2 factorial analysis. Attitudes toward psychodiagnostic testing were found to be related both to academic versus nonacademic professional expectations (academics scoring more negatively, M = 32.69, than nonacademics, M = 37.19), F (1, 107) = 5.994, p < 0.016, and to internship training exposure (non-interns scoring more negatively, M = 34.64, than interns, M = 38.80), F (1, 107) = 10.321, p< 0.002. Results paralleled previous research on academic and nonacademic working psychologists' attitudes. Similarities in students' and role models' attitudes were discussed in terms of Kelman's (1953; 1958), Festinger's (1957), and Bem's (1970) attitude theories. Results seemed to imply continued controversy over both the desirability of producing psychodiagnostically oriented clinicians, and also traditional paradigms of psychodiagnostic training.

Seven species of planktonic microcrustacea were identified from the North Texas State University Golf Course Pond. Total adult microcrustacean community density, biomass and biocontent, and seasonal cycles of each species were compared with northern populations. Species diversity and evenness indices were highest in summer and lowest in spring. Variations in microcrustacean density showed a positive correlation with density of phytoplankton. Temperature had a direct effect on metabolic rates of two species of copepods. Metabolic rates of pond species were lower at common temperatures than those of northern populations. An estimate of annual energy flow through the pond ecosystem showed cladocerans contributed the greater percentage of total energy to the next trophic level.

The purposes of the study were to compare ratings of perceived exertion of aerobic dance and treadmill performances under equal work loads and to compare ratings of perceived exertion by males and females in aerobic dance and treadmill work. Subjects were twenty-six college men and women in co-educational conditioning classes. Heart rates were monitored after work bouts and perceived exertion was determined using Borg's RPE scale. Data were analyzed by a two-way analysis of variance with repeated measures. Conclusions of the investigation were: (1) aerobic dance is perceived as less strenuous than the treadmill under equal work loads, and (2) males and females perceive aerobic dance as less strenuous than the treadmill under equal energy bouts.

Data on the life cycle of Hydropezrla crosbvi were collected from January, 1974, to March, 1976, in Clear Creek, Denton County, Texas. Laboratory investigation helped in establishing instar number, egg incubation and description, and first instar descriptions. Adult Hydroperla crosbyi emerge in February - March when water temperature increases to a mean of 15 C. Eggs undergo a diapause, hatching when decreasing water temperature reaches 18 C in October - November. Maximum growth occurs when water temperatures are coldest. Male and female nymphs undergo ca. 12 and 14 instars, respectively. Larvae of Simuliidae and Chironomidae are the preferred food items of nymphs throughout the growth season.

The purpose of the study have been: (1) to provide an explanatory, descriptive, and analytic viewpoint of the functions and structure of crisis intervention centers (2) to provide an intensive investigation of counseling and treatment practices in crisis intervention centers and (3) to relate the experiences that the writer has encountered as a resident counselor at Help House Inc. (twenty-four hour drug and crisis intervention center in Denton, Texas) to sociological, psychological, social psychological and philosophical constructs that deal with or pertain to crisis intervention, particularly in the area of drug use. The study indicates how participatory observation serves as an aid in acquiring insight into sociological areas such as crisis intervention centers. The role of the participatory observer is most important because concepts and theories arise out of actual situations.

To better understand abiotic dynamics in Southern reservoirs receiving heated effluents, water was analyzed before and after impoundment in 330 ha North Lake. Macronutrients, metals, and chlorinated hydrocarbons were measured. Concentrations of nutrients and metals in sediments were quantified in this 2 yr study. River water prior to impoundment contained 16 times more total phosphorus, and supported 23 times more Selenastrum capricornutum cells in an algal assay than reservoir water. The reservoir has essentially no drainage and since evaporation is high, the concentrations of many dissolved solids have increased since the reservoir was filled in 1958. North Lake is now phosphorus limited. Apparently altered chemical equilibria have caused precipitation or adsorption of phosphorus with calcium and iron.
