Proceedings of the Seventh Annual Summer Conference. NASA/USRA: University Advanced Design Program

The Advanced Design Program (ADP) is a unique program that brings together students and faculty from U.S. engineering schools with engineers from the NASA centers through integration of current and future NASA space and aeronautics projects into university engineering design curriculum. The Advanced Space Design Program study topics cover a broad range of projects that could be undertaken during a 20-30 year period beginning with the deployment of the Space Station Freedom. The Advanced Aeronautics Design Program study topics typically focus on nearer-term projects of interest to NASA, covering from small, slow-speed vehicles through large, supersonic passenger transports and on through hypersonic research vehicles. Student work accomplished during the 1990-91 academic year and reported at the 7th Annual Summer Conference is presented

Major Total Conversion in English: The Question of Directionality

This research investigates the directionality of major total conversion in English, where major total conversion is defined as the process and at the same time as the result of deriving a new lexical item by altering the part of speech of the base without marking the alteration overtly, as in the presumed pair dry – to dry. The question is whether there is a reliable strategy for deciding which member of a pair is the base and which member is the converted counterpart. Various attempts had been made to resolve the controversial directional issue, but the results have been inconsistent. The investigation aims to discover whether or not there exists a coherent notion about how to decide directionality by considering four factors assumed in the literature to reflect directionality. A large corpus of potential examples of major total conversion was collected to act as test materials. The four factors were compared for each major total conversion pair to see to what extent there was agreement among them. Results showed the factors did not agree to the expected extent. The findings are discussed in detail and it is claimed the inconsistencies can often be explained with recourse to a few general principles. In conclusion, on the whole the four factors considered are consistent with one another. In other words, the notion about how to determine directionality in major total conversion is coherent and can be maintained for English
