In this dissertation, I examine how the spatial configuration of forest ownership influences the risk-mitigating behavior of public and private forestland owners over time. I determine whether or not the predicted equilibrium outcomes are socially optimal and, if not, whether the introduction of regulation, liability, or private insurance would lead...
A five year longitudinal study was begun in 1976 to find a
solution to the problem of early primary children who fail in school
and then adopt the failure syndrome. The study was conducted in four
elementary schools in Oregon which had distinctly different
socio-economic populations.
The tests used for...
Calls for increased farmer involvement in research and extension programs
have been numerous and well supported. One approach to integrate the collective
knowledge and experience of agricultural scientists and farmers is through whole
farm case studies (WFCS). An interdisciplinary team of 34 research and extension
personnel at Oregon and Washington...
Near-surface advanced argillic hydrothermal alteration zones, also referred to as lithocaps, are characterized by quartz, alunite, clays (pyrophyllite and kaolinite group minerals), and minor F-bearing aluminosilicates (i.e., topaz, zunyite, diaspore, and APS) that form where water-, SO2-, and HF-rich gas condenses into shallow groundwater, acidifies, and reacts with rocks. The...
The purpose of this study was to determine the effects of long-term weighted vest
exercise on hip bone mass, functional ability and static balance in elderly women. This was
a within subject exercise intervention study and included a 6-month control period.
Twenty-three subjects (age 85 ± 6) were recruited and...
Academics and practitioners agree that in water governance, the quality of a decision making process should influence the quality of the outcome and the degree to which it is accepted by interested parties. However, finding a feasible way to evaluate and then improve the quality of a decision making process...
This investigation consisted of two parts: A. stability, B.
bioavailability of vitamin B₆ in wheat. Three variables; whole wheat
flour (WHW), white flour (W) and W enriched with vitamin B₆ (WB₆)
were tested.
Stability of vitamin B₆ during bread making and storage of
bread and flour was determined. Bread was...
A concept image is that collection of all images, pictures, symbols, definitions
and properties associated with any given mathematical concept. One of the
most important components in the mental representation of concepts in the concept
image of advanced mathematical thinkers is visualization. This component, in
turn, is indispensable in the...
Four aspects of factors influencing the accuracy of nondestructive chlorophyll (Chl) and nitrogen (N) measurement in fresh leaves were studied: (1) optimum wavelength (OW) identification; (2) indices development and evaluation; (3) influence of leaf properties; and (4) influence of meter parameters and sampling technique. Results were used to develop indices...
