This study describes the learning projects of a sample of engineers between the ages of 25 and 35 employed by a single employer in Port Worth, Texas. The problem of this study was the nature and extent of the continuing education programs of young engineers and the implications of these programs to their job requirements and possible employer assistance. The purposes of this study were to determine the number and types of learning projects undertaken each year by engineers with degrees, the number of hours spent by the subjects, the problems experienced, the resources used, the amount of job-related learning projects undertaken, the locations used to pursue learning projects, and whether the learning projects were amenable to assistance from employers.

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.

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 Major sources include such unpublished data as production and financial records of the theatre, contracts, correspondence, minutes of the board of directors, and interviews.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.

In this study, the relationship between maximal aerobic capacity (VO₂max) and left ventricular function was examined in two distinct age groups. A young group (20 - 30 years of age) and an elderly group (over 60 years of age) were compared. Left ventricular function was examined over wide variations in preload accomplished by 5º head-down tilt (TILT) for ninety minutes and lower body negative pressure (LBNP) to -40 mm Hg. with two-dimensional echocardiography. A greater response to an increase in preload (TILT) was related to high VO₂max levels in the young subjects but not in the elderly groups of subjects, suggesting that lower VO₂max levels of the elderly population affected the mechanism of response to the increased levels of preload. Additionally, in the elderly, greater reductions in ventricular volume reflected increased peripheral pooling due to decreased venous tone and/or increased venous compliance during LBNP and were related to increased VO₂max. In the young, VO₂max does not appear to affect the response to reduced preload.
