IMPORTANCE OF VARIOUS ROLES AND EVALUATION METHODS OF EXTENSION ECONOMISTS AS VIEWED BY EXTENSION ADMINISTRATORS, DEPARTMENT HEADS, AND SPECIALISTS

A survey of extension administrators, department heads, and extension specialists was conducted to determine the best methods for evaluating the performance of extension economists. The results demonstrate how different groups view the relative importance of the various roles played by extension economists and how important the specific attributes of extension economists are within each role. In general all three groups agree on the most important roles and attributes. However, important differences among the groups do exist about the relative importance of certain activities.Teaching/Communication/Extension/Profession,

Systems study for an Integrated Digital-Electric Aircraft (IDEA)

The results of the Integrated Digital/Electric Aircraft (IDEA) Study are presented. Airplanes with advanced systems were, defined and evaluated, as a means of identifying potential high payoff research tasks. A baseline airplane was defined for comparison, typical of a 1990's airplane with advanced active controls, propulsion, aerodynamics, and structures technology. Trade studies led to definition of an IDEA airplane, with extensive digital systems and electric secondary power distribution. This airplane showed an improvement of 3% in fuel use and 1.8% in DOC relative to the baseline configuration. An alternate configuration, an advanced technology turboprop, was also evaluated, with greater improvement supported by digital electric systems. Recommended research programs were defined for high risk, high payoff areas appropriate for implementation under NASA leadership
