The thesis discusses stability of procedures based on linear
computing formulas for numerical integration of an ordinary first-order
differential equation. The theorems are proved: (1) If the
procedure is asymptotically stable it is stable for small positive step
size if the Lipschitz number is negative; (2) Relative stability always
exists...

The hypotheses of this study stated the following:
Interaction with the computer game will significantly
increase the class means in: (1) mathematical
achievement, (2) attitudes toward mathematics, and (3)
graphing ability in high school advanced algebra.
ALGEBRA ARCADE is a computerized simulation game
played on a coordinate grid. One can...
Fifty-two one-meter plankton net samples from four stations off Newport, Oregon, were examined for composition and abundance of euphausiids and copepods. They provided data on dominance, species associations and environmental relationships. The euphausiid-copepod population off Oregon is composed of 12 numerically dominant species. These species occurred in most of the...
The Fishery Performance Indicators (FPIs) have been successfully applied to commercial fisheries around the globe and have uncovered key insights into fishery management success. We developed an extension of the FPIs to consider performance of recreational fisheries. The Sport FPIs were developed through multiple iterations of consulting, piloting and revision...
This paper examines the relationship between U.S. aquaculturists‟ intended actions to expand production capacity abroad and the factors influencing their choices. These factors include aquaculturists‟ perceptions of market conditions; regulatory climate; property rights; government leadership; and the comparative advantages of U.S. aquaculture, as well as the demographic characteristics of aquaculturists...
We carried out a detailed rock magnetic and paleomagnetic study of deep-sea sediments from selected intervals of Site 1233 in order to assess whether they contain reproducible evidence for submillennial-scale environmental, climatic, and geomagnetic field variability. Three 1.5-m sediment intervals from oxygen isotope Stages 1, 2, and 3 were sampled...
This paper is the result of a project that began with NAAFE 2015 special session on Fisheries Certification, which asked what forces are driving the market for sustainable seafood. Many previous studies looked at consumers' demand, but in this paper we looked at the entire supply chain (from producers to...
