This publication is part of the "Space in the Seventies" series and reviews the National Aeronautics and Space Administration's (NASA) earth orbital scientific research programs in progress and those to be pursued in the coming decade. Research in space physics is described in Part One in these areas: interplanetary monitoring platforms, small…

Various reported measures of clustering in free recall are reviewed under categories of algebraic versus probabilistic approaches. Shortcomings in these measures are outlined and a new multi-dimensional measure is advanced which overcomes many of the deficiencies noted. (Author)

This report is one of three publications from the task analysis study of ornamental horticulture conducted at Cornell University. It was designed to develop a procedural model for task analysis in the area of agribusiness. The personal interview method was used to collect data from businesses within nine identified areas of ornamental…

The article discusses an aspect of conductivity, one of the electrical properties subdivisions, and describes a tester that can be shop-built. Breakdown voltage of an insulation material is specifically examined. Test procedures, parts lists, diagrams, and test data form are included. (MF)

An instrument is presented for student rating of a physical education teacher's basic instructional program, covering (1) knowledge, clarity, and enthusiasm, (2) organization and presentation, (3) instructor-student interaction and rapport, and (4) general evaluation. (MJB)

The National Science Foundation's College Science Instrumentation Program (CSIP) provides four-year colleges with money to buy modern instruments. Accomplishments of the program during its first year (including 234 awards totaling $5.5 million) and future directions are summed up by Robert F. Watson, head of the CSIP program. (JN)

Reviews techniques for online coupling of high-performance liquid chromatography with mass spectrometry, emphasizing those suitable for application to nonvolatile samples. Also summarizes the present status, strengths, and weaknesses of various techniques and discusses potential applications of recently developed techniques for combined liquid…

A project was designed to expose students to the complexities of designing an instrumentation and control system for the overall plant design. Project objectives, format, and student activities, accomplishments, and shortcomings are described. (JN)

The purpose of this study was to determine the practicality of infrared photographic analysis to air pollution agencies, by the detection of plant damage from pollutants before they are visually identifiable. Results showed that photomicrographic imaging using infrared radiation should be considered a viable surveillance tool in similiar…

The Construction procedures and working drawing of an impact tester for wood or plastics materials testing. (GR)
