Economic theory predicts that individual migration decisions for working-age adults will depend on area differences in wages, housing costs, and amenities. While the importance of wages and amenities is well-established from previous empirical studies, evidence regarding housing costs is far less conclusive. We develop and test a new method for...
"This study examines the ways in which land-use regulations in general and Oregon's land-use planning system in particular may affect property values. The study is focused on Oregon, but it is framed within the broader context of research in economics. Our analysis of Oregon land value data finds no evidence...
Forty-nine genera and ninty-eight species of Lichenized fungi are reported from the H. J. Andrews Experimental Forest (Oregon). Substrates, growth form, and type of phycobiont are indicated for each taxon.
To increase the knowledge needed to successfully implement the ecosystem-based approach to fishery management, this dissertation investigates important issues within the economics of choice and the economics of displacement. In particular, a discrete choice model of the fishing location decision in the Newport, Oregon bottom trawl groundfish fishery is estimated...
To protect and restore environmental quality, efficient and effective conservation policies are needed. Designing policies require a sound understanding of the contributions of natural endowments to economic vitality, and the performance and impacts of conservation programs. This dissertation consists of three essays, and addresses several issues relevant to these two...
The H. J. Andrews Experimental Forest in the Cascades of
central Oregon provides a unique opportunity to study spatial
climate patterns on a relatively small scale. Historical
records at the 64 square-kilometer site provide a spatiallydense
30-year dataset. Thermal regimes at the H. J. Andrews
are generally known but the...
Chitosan based hemorrhage control dressings provide effective external hemorrhage control while having few side effects. Known residual contaminants present in chitosan formulations include endotoxins and proteins known to stimulate gene expression in the liver. This study investigated gene expression in the liver using rat bio-compatibility models to gain knowledge regarding...

This paper presents a framework for analyzing efficient spatial allocation of forest
management efforts - fuel treatment and harvest - under the risk of fire. The framework
integrates a fire behavior model and a spatially-explicit stochastic dynamic optimization
model. I investigate the effects of spatial interaction across plots during forest...
This dissertation used land rent theory and an economic model of land-use conversion to examine the main drivers of the deforestation occurred in Antioquia,Colombia, between 1980 and 2000. Land-cover information at a semi-fine scale (1:25,000)
obtained largely from aerial photography was employed to calculate deforestation. In addition, free international databases...
