The marine and freshwater fishery resources of West Africa are some of the most productive in the world, and hold vast potential to provide economic prosperity and food security for the developing nations of that region. Nevertheless, the realized social benefits from fishery resources to West African nations have fallen...
Working waterfronts across the nation are under pressure. Land use priorities of local governments are changing in response to population growth, new economic pressures, and shifting policy and politics. In Oregon, the decline of fisheries and timber in economic importance followed by the growth of tourism and retirement services has...
The Arctic has long been considered to be a pristine environment, far
from population centers and pollution sources. The detection of synthetic
organochlorine compounds in various elements of the Arctic food web has confirmed
the global dispersion of pollutants, particularly of persistent compounds such as
organochlorines and heavy metals. Levels...
A structural model of the Pacific halibut fishery is developed. Hypothesis tests
are developed within the framework of the "new empirical industry organization" for
the exertion of market power by Pacific halibut processors in both the exvessel market
and the wholesale market. The relationship of market power exertion and IPHC's...
Quantitative assessments of many West coast rockfish stocks of both major and
minor importance to commercial fisheries have shown varying declines in abundances. The population sizes of less-abundant, co-occurring unassessed species may also be
declining. However, determining stock status of the many non-targeted, minor species with high levels of certainty...
All animals that interact with fishing gear are not necessarily captured, and all animals that are captured are not necessarily retained. Fishing practices and gear configuration, management regulations, and markets dictate which animals ultimately are retained or discarded. The impact of a fishery and the efficacy of management regulations can...
Many parallel machines, both commercial and experimental, have been/are being designed with toroidal interconnection networks. For a given number of nodes, the torus has a relatively larger diameter, but better cost/performance tradeoffs, such as higher channel bandwidth, and lower node degree, when compared to the hypercube. Thus, the torus is...
Parallel solutions for two classes of linear programs are
presented. First we parallelized the two-phase revised simplex
algorithm and showed that it is possible to get linear improvement in
performance. The simplex algorithm is the best known algorithm for
solving linear programs, and we claim our result is the best...
Understanding seasonal migration and localized persistence of populations is critical for effective species harvest and conservation management. Pacific salmon (genus Oncorhynchus) forecasting models predict stock composition, abundance, and distribution during annual assessments of proposed fisheries impacts. Most models, however, fail to account for the influence of biophysical factors on year-to-year...
