This study seeks to show how a member of an empowered group is able to argue
on behalf of a disempowered group. Other theorists in the field of other-directed
protest have claimed that these protestors have a negative effect on the
disempowered group and only serve to raise their own...
Sweet corn (Zea mays L.) yields in the Willamette Valley of Oregon have been declining since the early 1990’s. Studies were done to determine if there is a relationship between ear weight and several disease parameters including necrotic crowns or stalk nodes, nodal root rot, radicle root rot, and sub-crown...
Disease detection through traditional techniques such as scouting fields on foot, molecular assays, or morphological identification of plant pathogens is time consuming and costly. Disease diagnosis in the field can be extremely subjective, and largely depends on the experience and knowledge of pathogen identification and disease quantification. This thesis provides...
Knowledge concerning trade wind cumulus, one of the most dominant cloud types
on the planet, has become increasingly important when considering global issues such as climate change due to their potential influence on the Earth’s energy budget. In this project, using data from the Rain in Cumulus over the Ocean...
This literature review will outline HPV vaccination rates among those ages 13-17, barriers to HPV vaccination and highlight physician recommendation, the strongest predictor of HPV vaccine uptake. It was found that only about 54.2% of adolescents between the ages of 13 and 17 are up to date with HPV vaccination...
This review aimed to identify the factors that influence human papillomavirus (HPV) immunization initiation and completion among adolescents and young adults. A review of literature pertaining to HPV vaccination was performed that used data published after 2012. It was found that the average HPV vaccination rate in the United States...
Commercial radish seed producers in the Willamette Valley of Oregon have observed a late season wilt in their seed fields. Twenty-two fields were surveyed for wilt in the Willamette Valley during June through August 2012 and 2013. Plants exhibiting wilt symptoms were collected from the fields and examined for vascular...
After an unusually high incidence of Fusarium canker was observed in commercial hop fields of the Pacific Northwest, field surveys were conducted and revealed that canker incidence ranged from 20 to 60% of bines sampled in six commercial fields, as well as wide-spread Hop stunt viroid infection in these six...
A necrosis at the tip of cones was observed on hop (Humulus lupulus), cultivar "Nugget", grown in Oregon in the early 1990's. Fusarium sambucinum and F. avenaceum were recovered from symptomatic cones in 1998 and preliminary inoculation experiments suggested both Fusarium species could cause hop cone necrosis. Studies were carried...
The purpose of this study was to investigate the primary factors affecting colony size, reproductive success, and foraging patterns of Double-crested Cormorants (Phalacrocorax auritus albociliatus) nesting at East Sand Island in the Columbia River estuary, the largest colony of this species on the Pacific Coast of North America. This colony...
