(CPFV) fishery. The CPFV fishery provides a variety of trip types to
support recreational anglers targeting several species including, tuna,
rockfish, yellowtail, and shark. Trips vary by fishing location, by length of...
This paper develops a count data model of target species and bycatch
production for an arbitrary number of species that handles correlation
between species and over time. The model is applied to a large observer
dataset for fishing trips taken from 1990 to 2008 for roughly 150 vessels
participating in...
Recent aggregate models of recreational participation have largely focused
on demand systems and choice models utilizing cross sectional data. While
these strategies may be advantageous for the estimation of welfare
measures, they have left unexplored the relationship between recreation
participation and general temporal economic trends. This research shifts its
focus...
Choices are often limited as the most popular alternatives reach capacity and sell out; thereafter, selection is over less preferred choices. In the context of nonmarket goods, willingness to pay (WTP) welfare measures provide an estimate of the value of characteristics – often calculated through the modeling of preferences using...
Fishery management actions focused on the conservation of non-target species may impact the productivity of fisheries in terms of target species. This article studies California’s drift gillnet swordfish (Xiphias gladius) fishery and investigates the impact of a recent regulatory measure aimed to protect leatherback turtles. A parametric approach is used...
Purchases made by marine recreational anglers are an important source of economic activity in coastal areas around the United States. In recognition of the economic contributions anglers make to coastal state economies, NOAA Fisheries conducts surveys every three to five years in order to gather data on expenditures made by...
Unilateral conservation of a transboundary resources, notably bycatch species, can lead to production, trade, and conservation leakages, losses in net benefits to society, and, paradoxically, increased rather than the intended decline biodiversity loss. A 2001 time-area closure of a key fishing area for the California-Oregon drift gillnet fleet harvesting swordfish...

This ethnography describes RV [recreational vehicle] seasonal migration as an adaptive, transhumant strategy. The study population is retired, transhumant migrants, who are members of a nation-wide, membership camping organization. Fieldwork was conducted over a period of seven months at two sites located on the West Coast. These sites reflect northern...
American meteorology was synonymous with subjective weather forecasting in the early twentieth century. Controlled by the Weather Bureau and with no academic programs of its own, the few hundred extant meteorologists had no standing in the scientific community. Until the American Meteorological Society was founded in 1919, meteorologists had no...
This talk will introduce the special session on the Economics of Bycatch. It will provide an overview of the session. It will then discuss in general terms a variety of incentive-based approaches to managing bycatch that give vessels greater flexibility to devise cost-effective solutions of their own making. These include...
This project hypothesizes that the use of multiple ground-based remote sensing methods can collectively characterize the geophysical signatures of four marked human burials at the Confederated Tribes of Siletz Indians historic period cemetery. If the geophysical signatures of the marked burials can be characterized, these signatures may be used to...

Advances in VLSI array processing have led to many new
parallel structures for real-time Digital Signal Processing (DSP)
applications. Among all the architectures, systolic arrays have played
an important role because systolic arrays have regular, local
interconnections with modular structure. In ordinary systolic arrays,
however, all processing operations and data...
