Modern agricultural erosion was studied using ¹³⁷Cs from
fallout as an indicator of erosion/deposition. The study area was a
285 ha agricultural watershed in the hilly western margin of the
Willamette Valley, a high winter rainfall zone in which fall-planted
crops are commonly grown.
Objectives of the study were (i)...
Implementation of. the Fishery Conservation and Management Act of
1976 affords opportunities for fishery expansion and economic development
in the Oregon otter trawl fishery. The changes stimulated by the
Act should occur, according to social science theorists, by the
diffusion of innovations from innovative fishermen to less innovative
fishermen, with...
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,...
The semantic differential technique was used to
quantify four interest groups' perceptions of twenty-six
Alaskan scenes. The scenes represented both panoramic views
and views of Mount McKinley from different sites in southcentral
Alaska. The perceptions were measured on six semantic
scales ("ugly-beautiful", "dislike-like", "unpleasantpleasant",
"unstimulating-stimulating", "level-mountainous",
and 'monotonous-varied"), and the...
Moire patterns have been identified by printers as
undesirable screen patterns caused by incorrect angling of
overprinted halftones. These patterns are being examined by
cartographers as a possible alternative to traditional methods
of producing patterned areas on maps. Map design guidelines
are needed before the use of moires can become...
Rapid increases in the recreational use of
the Lower Deschutes River Canyon threaten the quality
and diversity of downriver recreational experiences.
The concept of recreation experience management is
discussed and recreation experience management zones
for whitewater boating are delineated and described.
The purpose of land use planning, as conducted by the Forest Service, is to allocate land uses. The techniques employed in the current planning process fail to take location of the land allocations into account in any systematic manner. The resulting solutions may be inconsistent with planning goals; the land...
This thesis examines one aspect of social change in Nepal. Contact
with the outside world since 1951 has provided a non-traditional
means of achieving access to highly valued occupations, resulting in
the formation of an emerging elite. High caste status is no longer
absolutely necessary to gain access to education,...
American railroads have faced a declining share of freight
traffic relative to other modes. Although a variety of reasons have been
identified for this decline, most experts agree that a contributing problem
is that the rail system is overdeveloped with unprofitable branchlines.
Many economic models have been utilized to analyze...
