The Valuation of Riparian Fisheries in Southern and Eastern Africa
Turpie, Jane; Neiland, Arthur E.; Béné, Christophe - 2008
literature concerning economic valuations of river fisheries in eastern and southern Africa, extracting the best available … fisheries in eastern and southern Africa tend to be small-scale, labor intensive, artisanal fisheries. They have received … relatively little attention because they have limited commercial value compared to marine and lacustrine fisheries. However, they …

Multi-Market Trading for Cooperative Resource Management: An Application to Water Pollution and Fisheries
Horan, Richard D.; Shortle, James S. - 2011
Increasingly, environmental problems are recognized to involve linkages across multiple environmental variables (e.g., pollution and a fishery). Prior work on managing these complex, linked systems generally focuses on efficiency rather than implementation. However, implementation is important...

SEARCH, blackbox optimization, and sample complexity
Kargupta, H.; Goldberg, D.E. - 2009
The SEARCH (Search Envisioned As Relation and Class Hierarchizing) framework developed elsewhere (Kargupta, 1995; Kargupta and Goldberg, 1995) offered an alternate perspective toward blackbox optimization -- optimization in presence of little domain knowledge. The SEARCH framework investigates the...

Resource aggregation issues and effects in mixed model assembly
Burdett, Robert L.; Kozan, Erhan - 2003
In this paper we consider the problem of grouping machine and human resources in mixed model assembly process so that sequencing and scheduling decisions may be performed more efficiently. Resource aggregation can potentially and significantly improve production efficiency and throughput by...
