This follow-up study investigated the effect of a systems-oriented graduate
training program upon system thinking among practitioners who had completed training,
using a post-test only, treatment-comparison group design. The subjects consisted of
practitioners matriculated through two counselor-related programs at a medium-sized
college in the Northwest during the years 1985-1991. A...
It is crucial for the development of high quality products that design requirements are identified and clarified as early as possible in the design process. In many projects the design requirements and design specifications evolve during the project cycle. Shifting needs of the customer, advancing technology, market considerations and even...
This study evaluates the feasibility of retrofitting a rotary
dryer to a hog fuel boiler, using the boiler exhaust gases as the
drying medium.
Two simulation models were developed. As substantiated by experimental
measurement of existing boiler/dryer systems, each model
accurately predicts system performance given site-specific parameters
such as boiler...
Overcrowding is a serious problem in prisons and jails. Most
people who are in prison and jail have substance abuse
problems. Long-term, intensive, therapeutic community,
substance abuse treatment in prison has proven effective in
reducing arrests, amounts of incarceration and time until
first arrest. Jails, with their shorter times of...
Post-fire forest management commonly requires accepting some negative ecological impacts from management activities in order to achieve management objectives. Managers need to know, however, whether ecological impacts from post-fire management activities are transient or cause long-term ecosystem degradation. We studied the long-term response of understory vegetation to two post-fire logging...
