Describes potential benefits of increased efficiency, optimization, and improved communication derived from school district use of facility-scheduling software. (PKP)

Provides a tutorial on differential item functioning (DIF) and reviews DIFPACK, a new software package that is specifically designed to test for the presence of DIF. DIFPACK allows the user to test for standard unidirectional DIF, DIF in dichotomous items, DIF in polytomous items, and disordinal, or crossing, DIF. (SLD)

Examined the knowledge used by motel office personnel to manipulate computer software for everyday tasks. Results suggest that many of the competencies identified were context-specific, and that it may not be possible to apply generic knowledge if the user cannot relate it to the context. (SLD)

A revision of the initialization strategy is suggested for OSMOD, a method of nonlinear principal component analysis for multivariate nominal and/or ordinal data. The revision is effective in diminishing the possibility of obtaining locally optimal solutions with categorical data provided by the original version of OSMOD. (SLD)

Discussion of lack of room when downloading long searches onto a word processor focuses on three remedies: (1) choosing the right word processor; (2) using a utility program, such as CHOP2 or SPLIT.EXE; and (3) using the EDLIN program, which is part of a DOS disk. (five references) (LRW)

Describes the object-oriented paradigm (modeling a system by the objects that constitute it and the class relationships between objects) and presents examples of its application to automated library systems, including a model of a hierarchical and relational bibliographic database. Advantages and disadvantages of the paradigm for information…

Introduces a new column on personal computing and discusses changing uses for personal computers. Recent developments in computing periodicals--including the introduction of "PC/Computing," a major new magazine--are considered. An annotated bibliography lists 35 articles from the 1988 literature. (MES)

Discusses the use of CD-ROM as a medium for distributing software and documentation. Companies that are distributing public domain software are examined, distribution of software supporting specific hardware is described, re-purposing of discs intended for programers and technical support personnel is discussed, and a directory of firms is…

Provides an introduction to the use of communications software for remote access between microcomputers. Areas discussed include hardware requirements for these applications, software features that should be considered, security issues, and some disadvantages of remote control software. A directory of remote control software packages is provided.…

Discusses the current problems associated with computer viruses that affect system and software users and the frequency with which they occur. System security is discussed, steps to take to safeguard against damage by computer viruses are suggested, and anti-viral programs, or vaccines, are described. (LRW)

Factors to consider when selecting software include (1) current use in business, (2) curriculum needs, (3) availability, and (4) cost. Evaluation criteria include (1) copyright, (2) documentation, (3) compatibility, (4) vendor support, and (5) ease of use. (JOW)

A computer-assisted, K-fold cross-validation technique is discussed in the framework of canonical correlation analysis of randomly generated data sets. Analysis results suggest that this technique can effectively reduce the contamination of canonical variates and canonical correlations by sample-specific variance components. (Author/SLD)

Discusses issues to be considered when networking multimedia CD-ROMs. Topics addressed include CD-ROM networking software; license concerns; configurations for CD-ROM servers; data caching; SCSI devices; CD-ROM drives; workstation configurations, including minimum requirements for five popular CD-ROM titles; and system setup troubleshooting tips.…

Discussion of electronic image processing focuses on the need for indexing to ensure adequate retrieval. Highlights include icons, i.e., reduced pictorial surrogates; file staging; indexing languages, including examples of thesauri; and pictorial languages, including a HyperCard system. (Contains eight references.) (LRW)

Presents research findings from an empirical study of design strategies and knowledge used in object-oriented (OO) software design by programmers both experienced and not experienced with OO programming. Results indicated that levels of experience with OO programming affect the design process. (Author/JKP)
