Discusses the 1995 OCLC/NCSA Metadata Workshop that met to define a standard set of data elements for describing network-accessible information resources. These document data elements had to be simple enough for authors and publishers to use, to facilitate discovery and retrieval, and to be useful as a basis for descriptive cataloging. (JKP)

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…

This paper presents a simple 4 bit computer processor design that may be built using TTL chips for less than $65. In addition to describing the processor itself in detail, we discuss our experience using the laboratory kit and its associated machine instruction set to teach computer architecture to high school students. (Contains 3 figures and 5…

In addition to the input/output record format, the program flowchart, the program listing, and the program test output, eight documentation items are suggested in order that they may serve as a base from which to start teaching program documentation. (Author/AG)

An order-analysis procedure, which uses graph theory to extract efficiently nonredundant, unidimensional chains of items from multidimensional data sets and chain consistency as a criterion for chain membership is outlined in this paper. The procedure is intended as an alternative to the Reynolds (1976) procedure which is described as being…

The research program is designed to accomplish two primary objectives: (1) to obtain a basic understanding of the digital encoding algorithm under certain general conditions, and (2) to determine explicitly what kinds of practical digital encoding equipment should be used for the various tasks which require it. In order to accomplish these…

To provide a guide for both layman and computer specialists to the multiple definitions and language of computers, this glossary provides terms which have application in a wide number of areas related to computers. Each term is accompanied by a number which refers the user to the source from which each definition for that term originated. An…

SLIP (Symmetric List Processing) is a list processing system designed to be added to a higher order language (PL-1 in this version) so that the user has available to him list processing powers. The primary value of such a system is its data handling power. Through SLIP, one can set up lists of data, scan those lists, alter them, and read or write…

In releasing individual data for statistical analysis by outsiders, deletion of direct personal identifiers is sometimes insufficient to preserve confidentiality. This study discusses procedures for analyzing data from confidential files while preserving individual anonimity. Recommendations for specific procedures are made. (Author/JKS)

A program (FORMULA) is described which translates the systematic chemical names of steroids to structural formulas which, with a suitable graphic output device could be used for direct typesetting. (10 references) (Author)

A method of developing computer catalogs is proposed which does not require unit card conversion but rather the accumulation of data from operating programs. It is proposed that the bibliographic and finding functions of the catalog be separated, with the latter being the first automated. (8 references) (Author)

The computerized conversion of Wiswesser Line Notations to Ring Codes, using a two-part approach, and the set of computer programs generated for the conversion of ring systems are described. (9 references) (Author)

Some details are given explaining start up and conversion costs when library mechanization is undertaken. Cost trends for labor and computer equipment are briefly described which underscore the economics to be expected with the application of data processing in the library. (Author/NH)
