In addition to its longstanding recognition as an influential evolutionary process, interspecific hybridization is increasingly regarded as a potential threat to the genetic integrity and survival of rare plant species, manifested through gamete wasting, increased pest and disease pressures, outbreeding depression, competitive exclusion, and genetic assimilation. Alternatively, hybridization has also...
This study was designed to assess the effects of approval seeking motivation and social cost upon conformity to group norms which were inconsistent with personal values. Utilizing the Asch conformity paradigm, 321 subjects were exposed to a group opinion which was contradictory to one of their personal values. The results...
Chromium spills on soils are causing severe groundwater contamination
problems. To increase the performance of cleanup methods, the chemical behavior
of chromium in soils and its transport through soils have to be understood. The
objectives of this research were to investigate the sorption characteristics of
chromium(VI) in soil and to...
Commercial production of soybeans in Oregon has been limited. In
1977, less than 1,500 acres were grown, primarily in the Columbia Basin
area. However, interest in soybeans as a possible "new crop" for Oregon
has arisen because of the (1) recent strong soybean price, (2) the high
cost of transporting...
Feedlot finishing of beef cattle in Southern Alberta involves
income risk due to the variability of prices of feeders, feed and
finished cattle. Several strategies are available to reduce this
risk, including hedging of cattle on feed, participation in a Federal-
Provincial government and producer established income stabilization
program for...
A model was developed to simulate winter wheat production on
irrigated farmland similar to that found near Hermiston, Oregon. The
simulated farm is irrigated with a side roll sprinkler system. A well
is located adjacent to the wheat field and the water is delivered by
an electrically powered pump. The...
