Cyanobacterial harmful algae blooms (cyanoHABs) are a growing concern worldwide due to damage of ecosystems and threats to human health. Previous research indicates that plant humics from aquatic and wetland vascular plants are effective inhibitors of cyanobacterial metabolism and growth and may be useful as control agents for mitigating cyanoHABs....
A sample of 398 rural and urban homemakers who participate in the Oregon State University Extension Home Economics study group program were surveyed to identify their perceptions of quality in fresh fish purchased for home use. The need for quality indicators on labels of fresh fish, and household practices pertaining...
We present student perceptions of a new first-year engineering programming class that was designed by informed research practices. While the College of Engineering at Oregon State University saw a lot of major switching in the first year, there were not many students switching into computer science (CS). This could have...
The Sapelo Island National Estuarine Sanctuary (will be referred to
as Sapelo Island Estuarine Sanctuary) has been in operation since 1976,
but to this date no management plan has been drafted or implemented. Management

The purposes of this study were to (a) provide insight into the use of item response theory (IRT) with psychomotor skills, (b) assess the psychometric properties of the Test of Gross Motor Development (TGMD) using IRT, and (c) provide a basis for future studies of the TGMD using IRT. The...
QCritic is a rule-based critic for analog bipolar circuits. It functions as a post-processor for the SPICE simulator, making use of netlist, current, and voltage data. The program was written in OPS83, and demonstrates good run-time performance on a VAX 11/780. At present, the system contains rules for analyzing circuits...
