Computational and plotting problems are often encountered with the Johnson-Neyman analysis of covariance procedure (P. Johnson and J. Neyman, 1936) when using three covariates. Use of an appropriate design and contrast matrix for the general linear model and the Mathematica software system to overcome these problems is described. (SLD)

Geographic Information Systems (GIS) are a combination of maps and databases that provides geographical information not otherwise possible. The result of combining street data and geographic data is a precision map showing exact street locations. GIS can be used by delivery people, emergency vehicles, and taxicabs. (JOW)

Electronic meeting-support (EMS) software is a collection of computer tools that makes meetings more productive and is helping to redefine corporate and organizational decision making. EMS is groupware that speeds the pace of meetings, actively engages participants, and elicits high-quality input from participants. (JOW)

Discusses the ethical dilemmas related to computer-mediated evaluation. These include issues of anonymity, privacy, confidentiality, informed consent, the disposition of data, and "distance" evaluation. Among the challenges is the development of new notions of professional identity and responsibility. (SLD)

The New Media Consortium's Horizon Project is an ongoing research project that seeks to identify and describe emerging technologies likely to have a large impact in education and other industries around the world over a five-year time period. The chief products of the project are the "Horizon Reports", an annual series of publications…

Computer literacy has evolved from writing simple BASIC programs to using desktop productivity applications. The shift from mainframe to personal computer brought about the need to rethink computer literacy courses to introduce basic skills and familiarity using desktop productivity applications. While these skills remain important, the recent…

An Internet-based e-learning system offers many benefits over traditional learning environments. It provides a time, class size, and geographical location independent learning platform to students in addition to being able to consolidate e-learning content from a vast amount of Internet Web sites and deliver it to students. However, as the…

Computer-based career planning systems have been a reality for 25 years. Over this time span, the technology has changed dramatically--from very expensive, slow, low-storage mainframe computers to low-cost, fast, high-storage microcomputers. Similarly, the presentation made possible by the technology has changed from screens without color packed…

Decision Support Systems (DSSs) are computer-based decision aids to use when making decisions which are partially amenable to rational decision-making procedures but contain elements where intuitive judgment is an essential component. In such situations, DSSs are used to improve the quality of decision-making. The DSS approach is based on Simon's…

This paper describes how the computer program "Elections," was used to trace voting patterns during Super Tuesday, the U.S. presidential primary elections held on March 5, 1988. The voting results were entered into the computer as the primary returns were reported on national television. The computer mapping provided an improved means…

Notes on topics of interest, such as a new computer-based system designed to provide more anecdotal information about student performance than that provided on traditional report cards, and a security program in which after-hours security guards check in hourly by telephone with a computer. (JF)

Paper examines some of the problems and possibilities of interactive decision-making within the experimental context of an industrial problem production schedule. (Author)
