The relationship between therapist behaviors and outcome for middle- and lower-class couples in marital therapy.

Treated a sample of 77 distressed middle- and lower-class couples by 19 therapists using conjoint therapy. Batteries of tests that assessed marital satisfaction and communications skills were given pre- and posttherapy plus 3 and 6 months later. Couple and therapist therapy behavior were assessed using audio tapes of interview sessions. A variety of sex and social class differences were found that correlated with therapy outcome. The overall thrust of the findings suggests that no one marital therapy technique will be appropriate for the different sexes and with those of different SES backgrounds.

Temperature and manganese as determining factors in the presence of diatom or blue-green algal floras in streams.

Diatoms are usually the major component of the algal flora in many streams, although green and blue-green algae may be present. These experiments were designed to determine if high temperature or a shift in the chemical composition of the water might bring about a dominance of blue-green algae and/or green algae rather than a dominance of diatoms in the algal flora.The results of these experiments indicate that an average temperature of 34 degrees to 38 degrees C results in a shift of dominance in the algal flora from diatoms to blue-green algae. Furthermore, a blue-green and green algal flora of species typically found in organically polluted water in favored if the manganese content is a few parts per billion. If the manganese content averaged 0.02-0.043 mg/liter in the natural stream to 0.04-0.28 mg/liter in the recycled water experiment, a diatom flora remained dominant.
