This structural analysis examined fourteen television commercials using a method developed by Claude Levi-Strauss. The commercials were divided into two product groups, restaurant and cleaning products advertising, which made up the "myths" to be analyzed. Binary oppositions in each myth were identified and, according to the methodology, charted to reveal new relationships, and ultimately the hidden messages in the advertising. This study confirmed that television advertising does function in our society much the same as myth does in the primitive societies studied by Levi-Strauss. It offers answers to problems and upholds the existing order of things in that society, and it may function on more than one level to convey its messages.

This study consists of two parts, the completed videotape production and the production book. The videotape explores the history, organizational structure, and training requirements of the Dallas/Fort Worth Airport Department of Public Safety. A copy of the videotape is shelved in the North Texas State University Media Center Library. The production book describes background preproduction, production, and postproduction of the videotape. Problems, their effects, and solutions are described. The study concludes that an effective videotape can be produced in-house with limited time, equipment, and personnel, at a cost far less than commercially produced films. The study makes specific recommendations for guidelines and planning of future productions.

This study hypothesizes that the major barriers to expanded trade between the U.S. and Eastern Europe are systemic in nature. Using this approach, each political/ economic system is examined in an attempt to define the obstacles to foreign trade expansion, to describe the most important systemic and political factors at work, and to demonstrate how they have determined and will continue to shape the economic relationships between the U.S. and the countries of Eastern Europe. A final synthesis presents the two systems in a unified picture of the economic environment and concludes that significant trade expansion is unlikely in the near future due to basic systemic incompatibilities which impede the resolution of key foreign trade problems.

Biotransformation and biodegradation rate constants were determined for naphthalene, lindane, and phenol in water samples from three different sources. Rate constants produced from monitoring disappearance of the parent chemical (biotransformation) were compared to those obtained from mineralization of the chemical (ultimate biodegradation) by ¹⁴CO₂ evolution as well as acidification of the residual ¹⁴C-labeled compound (primary biodegradation). Rate constants were statistically different for the three chemicals. The water source affected the rate constants. When biomass measurements of the waters were considered and second-order rate constants were derived, there was no statistical evidence that this parameter gave a reliable rate constant statistic that could be useful in predicting the fate of any of naphthalene, lindane, and phenol in these waters.

The investigation is a historical survey tracing the development of Casa Mañana Musicals, Inc., Fort Worth, Texas, from its experimental beginning in 1958 as the first permanent musical arena theatre in the United States, through twenty-three subsequent seasons. The study includes a chapter on the origins of theatre and the influences behind its concept dating back to the 1936 Casa Mañana produced by Billy Rose. Subsequent chapters deal with the theatre's seasons and its struggle to gain acceptance. The theatre's more recent financial and labor problems are also considered. Major sources include such unpublished data as production and financial records of the theatre, contracts, correspondence, minutes of the board of directors, and interviews. Published sources include accounts in newspapers and periodicals.
