The goal of the study was to investigate the relationship between
nonverbal behaviors and frustration. As a part of the study an
instrument for the observation of nonverbal behaviors related to
frustration was developed.
The specific hypotheses investigated in this study were the
following:
Hypothesis One - A valid and...
Clearcutting is a sound silvicultural practice when exercised
in the proper environmental location. Foresters have learned through
bitter experience that clearcutting Douglas-fir forests, located on
droughty south-facing slopes, often leaves uncorrectable regeneration
problems. Thousands of acres of unproductive grass and brush throughout
the Douglas-fir region are unavoidable reminders of inappropriate...

LOCCOST is an interactive computer program that
predicts stump to mill logging costs, stumpage and net
present value of a harvest based on stand data, pond value
and logging parameters, entered by the user. The program is
intended for use by foresters to evaluate the economics of
different stand management...
Dispersal facilitates population health and maintains resilience in species via gene flow. Adult dispersal occurs in some species, is often facultative, and is poorly understood, but has important management implications, particularly with respect to disease spread. Although the role of adult dispersal in spreading disease has been documented, the potential...
Oregon's Special Farm Use Assessment program is investigated
in this paper for its effectiveness in preserving farmland from urban
sprawl. Basic research for this study was conducted in Jefferson
County, a rural central Oregon county. Data from a similar study conducted
in Washington County, an urbanizing northern Willamette Valley
county,...
A survey of partial cuts planted with bare-root seedlings, was conducted on the Prospect Ranger District, Rogue River National Forest, Oregon, during the 1977 summer season. The purpose was to assess stocking and its composition under present levels of canopy cover, and to determine relationships between canopy density and performance...
We evaluated the effect of capture depth and fish size on the ability of several Pacific rockfishes Sebastes spp. to resubmerge after hook-and-line capture and surface release. We observed fish as they were released into a bottomless floating enclosure, and we recorded submergence success within a 5-min time limit. Submergence...
