This research focused on the experiences of 15 low income Mexican women immigrants participating in MAS and Superando, two family literacy programs at the center of these women's sociocultural change. This research sought to understand the extent to which participation in these two programs empowers women to create change in...
The Columbia River Channel Improvement Project (CRCIP) was constructed along 166.6 km (103.5 miles) of Columbia River (from River Mile 3 to 106.5), which was from Interstate 5 Bridge (between Portland and Vancouver) to the river mouth, before emptying into the Pacific Ocean. It deepened the river by 0.9 m...

Recent developments in Distributed Temperature Sensing (DTS) have allowed new insight into the surface-to-ground water interaction. The continuous temperature measurement by the DTS allows for cool water inflows to be located during warm summer months. These cool water inflows can then be differentiated between ground water and hyporheic exchange. The...
Popular botanical dietary supplements marketed for management of menopausal symptoms, including hops (Humulus lupulus L.), red clover (Trifolium pratense) and licorice (Glycyrrhiza uralensis), were evaluated for their potential to alter CYP-mediated drug metabolism clinically and pre-clinically. Both hops and red clover had been reported to inhibit certain cytochrome P450 (CYP)...
This thesis documents a period of ecological and cultural change on a Willamette Valley, Oregon landscape. In particular, this study examines the Peavy Arboretum area and the cultural changes that accompanied the transformation of the landscape from an oak savannah in the mid-nineteenth century to a dense Douglas-fir forest in...
The Northern California Current (NCC) ecosystem exhibits extreme seasonal, interannual and interdecadal shifts in the abiotic environment and shifts in primary and higher production. This variability is also apparent in the spatial structure of the ecosystem with nearshore-shelf waters (<150 m isobath) being highly productive and having a different community...
In February 1905 the Oregon State Academy of Sciences formed in
Portland to promote scientific research and diffusion of scientific
knowledge in Oregon. The founders also planned to assist in the
discovery and development of the state's natural resources. The
Academy was the first scientific society in Oregon with professional...
Ceratomyxa shasta is a myxozoan parasite of salmonids and requires the freshwater polychaete, Manayunkia speciosa to complete its life cycle. The parasite’s distribution is currently limited to the Pacific Northwest region of North America and has been reported to cause substantial losses of both wild and hatchery salmonids. The spatial...
Urban landscape water use is increasingly a focus of water conservation efforts. This is especially true in the arid and semi-arid regions of the western United States where increased demand, environmental concerns, and extended periods of drought have created chronic water shortages. However, until recently, little attention has been paid...
Climate change is causing people around the world to experience extreme temperature and air pollution events such as wildfires more frequently, and for longer periods of time. Extreme heat events have been widely associated with an increased risk of emergency room visits, occupational heat-related injuries and illnesses, and mortality overall...
