Describes research aimed at investigating dynamically evolving database environments and corresponding schemata that allow storage and manipulation of variable length data, a variable number of fields per record, variable length records and fields, and dynamically defined objects. Proposes a new framework for dynamic database environments.…

The purpose of this paper is to show how data mining may offer promise as a strategy for discovering and building alternative representations for the data underlying asynchronous discussion forums. Presently, the instructor's view of the output of a threaded forum is limited to reviewing a transcript or print version of the written dialogue…

Textbooks and websites today abound with real data. One neglected issue is that statistical investigations often require a good deal of "cleaning" to ready data for analysis. The purpose of this dataset and exercise is to teach students to use exploratory tools to identify erroneous observations. This article discusses the merits of such…

Today, collecting, evaluating, and analyzing data--the basic concepts of scientific study--usually involves electronic probeware. Probeware combines sensors that collect data with software that analyzes it once it has been sent to a computer or calculator. Science inquiry has benefited greatly from the use of electronic probeware, providing…

A description is given of the structure and functional characteristics of three types of interactive computer graphic systems, developed by the Department of Computer Science at Carnegie-Mellon; a high-speed programmable display capable of displaying 50,000 short vectors, flicker free; a shaded-color video display for the display of gray-scale…

Computer data on the technical level of devices, their speed rates, and computer languages of two Oakland County Michigan area centers' business data processing skill programs are discussed to provide information for other area centers on various hardware, software, and teachware. (BP)

The use of computers in hospital clinical nursing and implications for the education of nurses were studied with a sample of 130 hospitals. Of concern was how computers were used, which hospital personnel used computers in health care, costs to educate staff nurses, and who teaches nurses about computers. Questionnaires completed by hospital data…

An information society is one in which the expression "to earn one's daily bread by the sweat of one's brow" appears decidedly anachronistic. People have been seduced by the rhetoric of novelty and confused by the surface significance of terms which have become accepted parts of everyday speech. What do rubrics such as information society,…

An interactive, self-guided program for the joint post-processing of bibliographic citations from the federal information centers of the Department of Energy (DOE), the Department of Defense (DOD), and the National Aeronautics and Space Administration (NASA) is described. The program, presently installed on the Intelligent Gateway Processor of the…

Uses of personal computers, or microcomputers (micros), by college business offices are discussed, with attention to safeguards. An advantage of using micros is that business officers can develop their own applications with purchased software and need not depend on the data processing staff. The micros, which are located in the business office and…
