A method of introducing a controlled degree of skew and kurtosis for Monte Carlo studies was derived. The form of such a transformation on normal deviates is given. Analytic and empirical validation of the method is demonstrated. (Author/JKS)

At the conference, which brought together many university representatives from the Pacific Rim, papers were presented yielding both individual problems, perspectives, and successes in computer networks and also group needs and development. In the first section of this report the status reports of networking in the Pacific Rim are summarized. Next…

This report provides a technical description and operating guidelines for the IMSAI 8080 microcomputer in the Department of Secondary Education at the University of Illinois. An overview of the microcomputer highlights the register array, address logic, arithmetic and logical unit, instruction register and control section, and the data bus buffer.…

A family of models for the representation and assessment of individual differences for multivariate data called PINDIS (Procrustean Individual Differences Scaling) is presented. PINDIS sheds new light on the interpretability and applicability of a variety of multidimensional scaling models. (Author/JKS)

A Monte Carlo study investigated the ability of the ALSCAL multidimensional scaling program to recover true structure inherent in simulated proximity measures when data were missing. The program worked well with up to 60 percent missing data as long as sample size was large and random error was low. (Author/JKS)

An error is described that may occur in a posteriori testing, particularly when the original analysis of variance produces an F ratio that is just barely significant and the computer printout of the analysis does not provide the means that were used in the program. (Author/JKS)

Two revisions of computer-interactive multidimensional scaling data selection procedures are presented. One revision--based on randomly ordering the list of stimuli--improves the estimates of the multidimensional scaling parameters and the other permits more efficient data designs. (Author/JKS)

A Data Element Dictionary/Directory (DED/D) is a software tool that is used to control and manage data elements in a uniform manner. It can serve data base administrators, systems analysts, software designers, and programmers by providing a central repository for information about data resources across organization and application lines. This…

This report covers the PLATO IV activities during calendar year 1973 at the Computerized Training System. The work reported herein is supported by a program sponsored by the Advanced Research Projects Agency (ARPA) to evaluate the PLATO IV system for use in training, oriented to the needs of the Armed Services. The report presents a synopsis of…

Interim work is documented describing efforts to modify computer techniques used to recognize and process English language requests to an instructional simulator. The conversion from a hand-coded to a table driven technique are described in detail. Other modifications to a simulation based computer assisted instruction program to allow a gaming…

The repertory grid analyzed by new methods of computer analysis is a sensitive instrument allowing individuals to model any topic in terms of personal constructs. Useful computer programs include FOCUS, PEGASUS, MINUS, CORE, SOCIOGRIDS, and ARGUS. (Author)

This basic introduction to microcomputers provides the neophyte with the terminology, definitions, and concepts that explain the microcomputer and computing technology in general. Mathematical operations with binary numbers, computer storage, controlling logic, and the concepts of stack and interrupt are explained. (RAO)

In this study the advantages and problems involved in using Generalized Data Management Systems (GDMS) to expand the capabilities of information retrieval (IR) systems are investigated. In particular, the design of a Data Manager-1 (DM-1) based system for the Reliability Analysis Center (RAC) at Griffiss AFB, Rome, New York is studied. A design…

A year-long study of the Writing to Read System provided highly significant findings. Kindergartners and first-grade students in the program showed writing skills well above their grade levels. (MD)

Describes work performed under the Spelling Error Detection Correction Project (SPEEDCOP) at Chemical Abstracts Service to devise effective automatic methods of detecting and correcting misspellings in scholarly and scientific text. The trigram analysis technique developed determined sites but not types of errors. Thirteen references are listed.…
