This study develops an improved method for understanding
economic production relationships in small scale
fisheries. This method postulates that gross revenue is a
function of physical input quantities, and is based upon
the transcendental logarithmic function to derive factor
share equations for each of the five inputs in the model....
Among other mechanisms, the Chilean fishing act established a system of extraordinary fishing permits (EFP) to access the fisheries in stage of recovery or incipient stage of development. The EFP entitles its holder the right to catch during 10 years a fraction of the global annual quota. The right is...
The present article describes the changes that took place, in terms of efficiency and distributional issues, within
Chile’s central-southern pelagic fishery industry when the administrative regime evolved from controlling the
fishing effort to assigning individual fishing quotas. These changes are described through a set of indicators that
reveal variations in...
The demersal fishery of southern Chile is a complex system including multiple species, fishing fleets and markets. Fishing activity is conducted under a rights-based system for southern hake (Merluccius australis) and hoki (Macroronus magellanicus), where a TAC is allocated in an even manner among fleets and operators. New management approaches...
This paper illustrates a case study to identify problems and actions to build the basis for an integrated fishery management plan, considering stakeholders participation. The application was made on the southern complex multispecies groundfish fishery, where operate various scales of production under a right-based fishing system. A multimethological approach (Mingers,...
This thesis focuses on the economic efficiency of alternative habitat, streamfiow, and land use
allocations within a major drainage of the Pacific Northwest. Specifically, productivity of present habitat
and streamfiow conditions is evaluated with respect to anadromous fish species (chinook salmon and
steelhead trout) in the John Day River Basin,...
The alternators in today's automobiles are of the claw-pole or Lundell
construction, which is a readily manufactured, low-cost derivative of the conventional
rotating dc field synchronous generator. The efficiency of the Lundell system is low due
to a complicated magnetic circuit of predominantly solid steel and a high windage rotor...
A sucrose density-gradient ultracentrifugation technique for
obtaining microsomes has been developed. This technique has
advantages over the classic differential centrifugation technique, in
that it is faster, is better suited to work with small quantities of
tissue, and offers the opportunity to work with a defined microsomal
sub-cellular fraction, rather than...
The Brushless Doubly-Fed Machine (BDFM) has recently become an
important research topic in the field of variable-speed AC drives. In
recent studies, the BDFM has shown significant potential for improving the
reliability and performance of AC drive systems, as well as reducing total
system cost. While the BDFM offers several...
