Responses of phytoplankton productivity in the Red River to unbleached pulp and paper mill wastewaters were monitored using in situ ^14C incubation. Preoperational studies, conducted prior to the discharge of mill wastewaters varied seasonally, but revealed similar productivity trends when compared with postoperational studies, conducted after mill discharges began entering the Red River. Carbon assimilation rates measured downstream of mill discharge were generally greater than upstream levels in both preoperational and postoperational studies. Selected physical, chemical, and biological parameters varied seasonally, but showed similar upstream-downstream values and preoperational-postoperational values. Total Organic Carbon (TOC), Dissolved Organic Carbon (DOC), and Biochemical Oxygen Demand (BOD_5) were positively correlated with postoperational productivity rates. Apparent color was negatively correlated with productivity rates.

The Life of Ben and Other Poems consists of two sections. The first, The Life of Ben, is a series of seventeen poems about the life of a first-generation American and his family's immigration. The second section, Other Poems, includes twenty-one poems on a variety of themes.

Federal guidelines required prime sponsors under the Comprehensive Employment and Training Act, or CETA, to serve the "significant segments" of the eligible population. This study analyzes whether prime sponsors in Texas and Louisiana correctly identified and served those segments. This study finds that eligible ethnic groups were properly identified and were served equitably; age and gender distinctions, however, were inadequately observed in the providing of services.

This screenplay dramatizes the controversial career of German film maker Leni Riefenstahl during ten years of her association with the Nazi Party. Beginning with the premiere of her first film in 1932, this account chronicles her rise as a film director of such films as Triumph of the Will and Olympia to her arrest after World War II on charges that she had been a Nazi sympathizer. Besides delineating the character and talents of Leni Riefenstahl, this screenplay addresses the difficult question of the relationship between politics and art.

The paper documents the need for an effective technology to teach problem-solving. It asserts that a behaviorological analysis of problem-solving can speed the development of an effective technology to teach problem-solving behavior. A behaviorological definition of problem-solving is proposed. The history of behaviorological approaches to problem-solving is traced and suggestions are offered that may facilitate further empirical and theoretical work. One application of a behaviorological analysis to the teaching of problem-solving is illustrated by some preliminary data on the effectiveness of a technique for teaching a type of problem-solving behavior. Suggestions for further research are provided.
