The applicability of electromyographic biofeedback toward alleviating
test taking anxiety was examined along with the effects of
relaxation training on general anxiety, locus of control, test performance,
and muscle tension during a test. The Achievement Anxiety
Test (AAT) was administered to 271 freshman psychology students.
Students whose scores indicated high...
Overcrowding is a serious problem in prisons and jails. Most
people who are in prison and jail have substance abuse
problems. Long-term, intensive, therapeutic community,
substance abuse treatment in prison has proven effective in
reducing arrests, amounts of incarceration and time until
first arrest. Jails, with their shorter times of...
Narcolepsy is a complex of physiological and behavioral
symptoms. The most striking of these are: excessive daytime
sleepiness, extremely short latency to rapid eye movement (REM)
sleep, hypnogogic hallucinations; sleep paralysis, and cataplexy,
which is loss of skeletal muscle tonus in response to intense
emotions such as surprise, anger, laughter,...
An important inoculum source of Leptosphaeria maculans and L. biglobosa (syn Plenodomus spp.), the pathogens that cause black leg in Brassicaceae crops, is infected plant residues. The general acceptance of conservation tillage in the Willamette Valley, Oregon, USA, has enabled a build-up in the amount of residue on or near...

Producers in the Willamette Valley of Oregon are interested in growing canola as a rotational crop in grass seed and cereal rotations. Many other Brassicaceae seed crops also are produced within the valley. Concerns of seed persistence and volunteer contamination of Brassicaceae seed crops prompted the investigation of seed persistence...

Soil solarization is a pre-planting practice to reduce weed pressure by trapping solar energy using a transparent polyethylene film to heat soil. Soil solarization has been successfully used in regions with high solar radiation. The purpose of this research was to determine if soil solarization under Pacific Northwest conditions could...
Perennial ryegrass (Lolium perenne L.) is a widely grown cool season, bunch type, short lived perennial grass that is native to Europe, Asia, and North Africa, but has been adapted globally. Perennial ryegrass is quick to establish, has a long growing season, and produces high seed yield and forage or...
Imazamox-resistant wheat (Clearfield®) cultivars carry the Imi1 gene, which confers resistance to the imidazolinone (IMI) herbicide imazamox. Imazamox provides selective control of jointed goatgrass and other weeds in IMI-resistant wheat. Imi1 gene flow between IMI-resistant wheat and jointed goatgrass may occur via hybridization and backcross events. In 2009 and 2010,...
Italian ryegrass (Lolium perenne spp. multiflorum) is a common weed management problem in turfgrasses, cereals and non-crop areas in the United States. In Oregon, the number of populations with multiple-resistance continues to increase. To manage these resistant populations, the resistance patterns must be determined. In this study, five Italian ryegrass...
Hybrids between wheat and jointed goatgrass have long been presumed to be sterile; however, seed were found on hybrid plants in 1990. Field studies were conducted in 1995 and repeated in 1996. One to ten hybrid plants were planted in variable populations of wheat and jointed goatgrass to determine the...
