This investigation has determined the presence of biological nitrogen fixation in two reservoirs in the southwestern United States: Lake Arlington and Lake Ray Hubbard. Subsequent tests have gathered baseline data on the effects of various biological, chemical, and physical parameters on in situ nitrogen fixation in these reservoirs. Of specific importance is the relationship between nitrogen fixation arid occasional blooms of blue-green algae which produce such problems as testes and odors in these water-supply impoundments.

The problem was concerned with determining what skills were necessary for the employment of the mentally retarded and what guidelines may be used in developing these skills in the secondary level industrial arts program. The study developed guidelines which should prove useful to an industrial arts instructor having mentally retarded students in his classroom. The guidelines were based upon the results of an industrial survey and available literature.

The problem of this study was to develop a proposal for the teaching of poetry for the purposes of contributing to the student's understanding and enjoyment. Surveys and summaries were made of scholarly writings on the junior college student, existential theories of education, and theories of poetry. A bibliography was constructed for each subject from resources of the North Texas State University library. Conclusions from each survey were derived from the selected resources and used to prepare the proposal for instruction of poetry.

The study conducted consisted of an interview with forty-eight varsity baseball coaches of the University Interscholastic League high schools within the Dallas-Fort Worth metroplex. Overall the coaches were found to be a highly qualified group of physical educators. Findings of the study included data on the playing experience, coaching experience, and educational backgrounds of the coaches. Physical education/ coaching areas investigated included: 1) medical-legal, 2) sociological and psychological, 3) kinesiological, 4) physiological, and 5) theory and techniques of coaching. Recommendations included continued professional involvement of coaches, further studies on professional preparation, a course in legal liability, and implementation of a "coaching endorsement".

The purpose of this study was to determine if seminary students, identified as conservative, moderate, or liberal in theological beliefs, were significantly different on the following personality variables: dogmatism, thinking introversion, theoretical orientation, aestheticism, complexity, autonomy, religious orientation, impulse expression, anxiety level, practical outlook, and personal integration. The instrument used to measure theological beliefs was the "Inventory of Theological Beliefs." Dogmatism was measured by the "Rokeach Dogmatism Scale." All other variables were measured by the Omnibus Personality Inventory.
