Methods of Studying Mexican Peasant Personality: Rorschach, Tat and Dreams

This study has two aims. One is to use -the Rorschach test, the TAT, and dreams as means to understand the personality of a peasant woman living in Tzintzuntzan, Michoacdn, Mexico. The other aim is to compare the methods, their strengths and weaknesses. The results show that while the three methods give a consistent and complementary picture of the personality, each provides material that is not to be found in the other two. The most formal material on endowment and on character forces that block the full development of innate capacities is to be found in the Rorschach. The TAT provides the best material on interpersonal sensitivity. It also shows conscious goals and values more clearly than the other techniques. The dreams express emotions better than the other material. Each of the methods appears to have built-in limitations as well as possibilities.

Stabilized Constant Acceleration Mössbauer Drive

A closed feedback loop for the zero velocity drift of a constant acceleration Mössbauer spectrometer has been developed. Using a transducer with a built-in limit switch and the modified logic circuitry of a multi-scaler-analyzer, the feedback loop responds to the zero velocity drift of the entire system as a whole rather than to each component independently. A long-term zero velocity stability of ±0.001 mm/sec has been obtained.

Automation and the price of progress.

Our inability to cope with automation appears to be due to our misuse of intellectual talent in the arms and space race. There is not scientific and organizational strength to create useful work for the presently unemployed. Automation by itself has too many built-in limitations and there are too many unmet needs of our society for us to speak of a permanent problem.
