Describes the major aspects of a 20-lecture introductory course for environmental science students, showing how microcomputers can help teach dynamic systems concepts. Also discusses the continuous stirred tank reactor as a simple dynamic system, higher order systems, frequency response, nonlinear systems, and feedback control. (JN)

Addresses problems encountered by self-taught "talented amateurs" doing microcomputer systems work for libraries: not maintaining design control, not maintaining operational control, attempting to use someone else's database, having variety of diverse systems activity converging on common database, attempting to run whole show, and…

This essay examines ways in which microcomputers are currently used in libraries and suggests practical considerations for those about to embark on automation projects. Sources of information on library automation, the overselling of microcomputing power, systems analysis, and factors to consider in purchase justification are highlighted. Four…

Arguing that the production system for computer courseware has a strong impact on quality courseware development, this report offers an introduction into the relationships between instructional system design and software engineering, and investigates courseware quality as a means of identifying quality enhancement factors that can make the…

Discusses the evolution of mainframe and personal computers, and presents a case study of a network developed at the University of Iowa called the Iowa Computer-Aided Engineering Network (ICAEN) that combines Macintosh personal computers with Apollo workstations. Functional objectives are stressed as the best measure of system performance. (LRW)

Previous work assessing the effectiveness of computers in education has gone no further than acknowledging a network of interconnected variables (comprising a system) which contribute to computer impact and describing its component parts. An impact systems model developed by Glasman and Bibiaminov (1981) has been adapted to facilitate measurement…

This checklist provides guidance on how to measure adequacy of control and security of computer systems, identifies areas of risk, raises management and user awareness of their stewardship responsibilities, and reviews issues relative to system documentation, maintenance, integrity, and reliability. (MBR)

These five papers by speakers at the Small Computers in Libraries 1987 conference include: "Acquiring and Using Shareware in Building Small Scale Automated Information systems" (Samuels); "A Software Lending Collection" (Talab); "Providing Subject Access to Microcomputer Software" (Mitchell); "Interfacing Vendor…

The availability of micro-to-mainframe communications software has provided computer thieves with new tools. Explains how to establish and maintain proper electronic data processing controls. (MLF)

An office automation audit is a comprehensive review of the existing and planned office hardware, software, staffing, and management. Factors reviewed include: standards, physical setup, storage facilities, disaster recovery, equipment protection and utilization, software adequacy, and staff training and adequacy. (MLF)

A simulation model is developed to reflect characteristics of a typical information retrieval system on three specific microcomputer configurations using Cromemco System 3, Apple II, and Telima 1000. Systems are compared in terms of installation costs, think time, multiprogramming level, response time, and main storage utilization. Three…

Outlines the important factors to be considered in selecting a database management system for use with a microcomputer and presents a series of guidelines for developing a database. General procedures, report generation, data manipulation, information storage, word processing, data entry, database indexes, and relational databases are among the…

Research on using computers in teaching economics in Great Britain has led to the conclusion that they are most useful for simulating complex systems and providing the means to analyze data and not so useful for providing feedback on learning. A nationwide competition for secondary students is also discussed. (IS)

Undertaken at the request of the Ad Hoc Statewide Automation Committee, this report provides a common understanding for Maine librarians of current library networking and how it might apply to Maine. The current status of Maine libraries and their cooperative and automation activities is summarized; resource-sharing in other states is examined;…

The result of a two-week consultant mission to the South East Asian Ministers of Education Organization (SEAMEO) at Bogor, Indonesia, this study explored the feasibility of applying microcomputers to library and information work in the Clearing House for Information Division of BIOTROP, which has a regional responsibility for the collection,…
