In 1989 the US Department of Transportation (DOT), Federal Emergency Management Agency (FEMA), and US Environmental Protection Agency (EPA) released a set of models for analysis of chemical hazards on personal computers. The models, known collectively as ARCHIE (Automated Resource for Chemical...

This paper provides new estimates of depreciation rates for personal computers using an extensive database of prices of used PCs. Our results show that PCs lose roughly half their remaining value, on average, with each additional year of use. We decompose that decline into age-related...

Computers are becoming an affordable and effective tool for assisting with classroom instruction. This paper describes experiences utilizing a hypermedia presentation system for a farm management course. Some advantages as well as drawbacks and issues associated with using...

A dynamic programming algorithm is proposed for a class of nonpoint source pollution control problems. The inherently combinatorial nature of these problems--stemming from the discrete nature of the decision variables, which are production and conservation practices--gives them a special...

This paper presents a prototype model for a microcomputer generated integrated planning, budgeting, reporting, and management information system suitable for agricultural research organizations in developing countries.

This paper is intended to serve as a starting point for agricultural scientists and other researchers in developing countries in need of a citation database manager.

This paper is a 1984 update on cost-effective microcomputer data collection, management, and analysis techniques for developing country applications.
