This report refines and improves upon a conceptual model and a mathematical procedure, based upon a blend of Likelihood Function Estimation (LIFE) and utility theory. Empirical studies conducted by the Air Force Military Personnel Center in 1975 and 1976 have shown that the LIFE procedure can be very useful in the prediction and study of…

This report reviews what is known about the role of vocabulary knowledge or knowledge of word meanings in reading comprehension. It states that while an assessment of the number of meanings a reader knows enables a remarkably accurate prediction of an individual's ability to comprehend discourse, the reasons why word knowledge correlates with…

This bibliography, directed to researchers and practitioners in cable television (CATV), has two purposes. The first intent is to summarize chronologically earlier bibliographies; the second is to provide a comprehensive coverage of information which has more recently been made available. The 461 citations from 1973 through June 1976 are listed in…

This text, a revision and extension of the first three editions, consists of papers discussing the basic considerations in sampling air for specific purposes, sampler calibration, systems components, sample collectors, and descriptions of air-sampling instruments. (BT)

Unobtrusive measures in psychological experiments are discussed. Six levels of unobtrusiveness are (1) Complete Unobtrusiveness, (2) Hidden Mechanical Intervention, (3) Hidden Observer, (4) Impinging Mechanical Intervention Not Recognized as Experimental, (5) Impinging Observer, and (6) Unobtrusive Measures within an Experimental Setting. Each of…

One year after the Union of Soviet Socialist Republics' accession to the Universal Copyright Convention a survey by the National Science Foundation revealed certain trends in U.S.-U.S.S.R. negotiations for their rights to reproduce and translate scientific and technical journals. For some U.S. publishers (Scientific and professional societies,…

This paper provides the description, documentation and users' and programmers' guide for the keyword out of context (KWOC) library indexing system, with coding references, program flow charts, program listings, procedure flow charts and instructions for maintenance and operation. (Author)

The product and process goals for the schools of Kentucky are outlined in this brochure. The product goals relate to learning skills, an appropriate knowledge base, economic productivity and recreational satisfaction, functioning effectively as a citizen, human relations, and physical and mental health. The schools seek to attain process goals…

Use of the computer in the design and operation of broadband communication systems are discussed. The current status of computer aided design is reviewed, with consideration ranging from components to total systems and networks. Future applications of computers to design, simulation, operation, maintenance, and economic modeling and…

A model for the systematic generation of verbal instructional cues is presented. The model utilizes a task analytic procedure referred to as "Maneuver Analysis," which is outlined and applied to the maneuver Vertical S-A. The cues generated on this basis are compared to current operational cues as found in "How to Fly" manuals,…

The problem of generating verbal cues to facilitate psychomotor skill training is considered in the context of flight instruction. The flying task is conceptualized in terms of a pilot-aircraft closed loop control system. The control system model effectively illustrates the three types of informational stimuli necessary for the pilot's effective…

A technical, user and cost comparison study was undertaken to provide the Educational Resources Information Clearinghouse (ERIC) staff with data on silver halide, diazo, and vesicular type films for microfiche duplication. This information will allow ERIC to determine if diazo and/or vesicular films should be considered in producing ERIC duplicate…

A new formula is developed for the relative efficiency of two tests measuring the same trait. The formula expresses relative efficiency solely in terms of the standard errors of measurement and, surprisingly, the frequency distributions of true scores. Approximate methods for estimating relative efficiency may make this function routinely…

Least cost decision rules for transferring documents from primary to secondary storage are developed from a dynamic programing model of an information system. The program is constrained to provide for a minimum acceptable level of user benefits. Knowledge of the physical size of the primary storage area and the fraction of documents returned from…

In multivariate analysis of variance the canonical variates of one effect may be correlated with the canonical variates of another effect. When the two effects are an interaction and a main effect this correlation interferes with the interpretation of the main effect. When the two effects are both main effects the interpretation of the common…
