This study was an investigation to determine the instructional
media competencies that inservice teachers of secondary education
teaching disciplines recommend for pre-service teachers in their
discipline.
A literature review focused on four main questions:
1. What historical events mark the development of the field
of instructional media?
2. What are...
An important issue in engineering education is the availability of laboratory resources for student use. Using a computer network to link geographically distant students with laboratory teaching resources makes expensive and innovative equipment available to more students. At Oregon State University, we provide a working environment where remotely-located students can...
This annotated bibliography was compiled to provide a comprehensive list of sources on the ecological factors that affect forest regeneration. Abstracts from 494 publications are indexed by author, species, and subject, and are arranged into 4 major sections. Topics include the effects of biotic factors, abiotic factors, and stand and...
The development of modern industries calls for the
robotic manipulators with high speed and accurate tracking
performance. Many authors have paid attention to robust
control of robotic manipulators; however, only few authors
have also considered the control problem of manipulators
with power limitation.
In this dissertation, the robotic manipulator is...
Eight foodborne pathogenic and spoilage Gram-positive bacteria were
evaluated for their spontaneous resistance frequencies to the peptide
antimicrobial nisin. In brain heart infusion (BHI) medium, nisin resistance
frequencies were in the range of l06 to l08 when exposed to nisin at
concentrations 2 to 4 times the minimal inhibitory concentrations....
Objective of this study was to compare accuracy of
several travel cost methods, by employing Monte Carlo
simulations in the single site framework. Estimates from
five methods were compared to the "true" travel cost
coefficient and "true" consumer surplus. Each method was
ranked, using the root mean squared error (RMSE)...
