Large wood (LW) pieces are recognized as an important habitat component for salmon freshwater habitat. As such, they are often used in stream habitat restoration practices despite a lack of knowledge about their impacts on spatial and temporal hydraulic characteristics relevant to fish habitat. In this thesis we present results...
Low-tech habitat restoration techniques, including Stage 0 treatments, are increasingly applied but often lack robust evaluation of their effects. In 2018, one kilometer of the South Fork McKenzie (SFMK) River, OR was modified to the Stage 0 condition for the benefit of ESA-listed Chinook by raising the incised channel to...
Health officials have recently been sounding the alarm that depression will soon
surpass many of the major medical conditions in causing disability among adults. Recent
demographic and health trends are generating public health concern about depression.
First, the prevalence of chronic conditions has dramatically increased over the last several
generations....
Wet meadow ecosystems are a useful natural laboratory in which to explore feedbacks between biogenic and geologic controls on valley bottom landforms. Characterized by flat valley floors flanked by higher-gradient hillslopes, these meadows are singular both in that they represent depositional features in what is primarily an erosional environment, and...
Co-teaching and collaboration are an increasingly popular service model for English as a second language (ESL). In this model, the language specialist, sometimes called the ESL teacher, works together with a content teacher, each using their respective expertise to meet the needs of students who are identified as English learners...
Shallow subsurface flow and surface runoff are spatially and temporally variable in forested environments. The location and timing of this runoff depends on both site characteristics (e.g., vegetation, soil texture, geology, and topography) and on time-varying conditions (e.g., soil water content, precipitation type, duration, magnitude, and intensity). Forest management activities...
Neisseria gonorrhoeae is the sexually transmitted pathogen responsible for millions of cases of gonorrhea worldwide each year. Rapidly-spreading antibiotic resistance is diminishing the ability to effectively treat a disease with significant consequences to female and male reproductive health, as well as to neonatal well-being. A protective vaccine has the potential...
The scientific endeavors that took place at Hanford Engineer Works, beginning in World War II and continuing thereafter, are often overlooked in the literature on the Manhattan Project, the Atomic Energy Commission, and in regional histories. To historians of science, Hanford is described as an industrial facility that illustrates the...
M. avium subsp. hominissuis (MAH) and M. abscessus subsp. abscessus (MAB) both belong to the clinically important non-tuberculous mycobacterial (NTM) group that infect immunocompromised patients with AIDS and individuals with underlining lung conditions such as bronchiectasis or cystic fibrosis. The main challenge of treating MAH and MAB patients is an...
Residents in South Falls City, a small town in the foothills of Oregon's Coast Range, battle intense flooding during the rainy season. Disagreements about surface water management pit neighbor against neighbor, but preliminary evidence suggests that groundwater flooding is an underlying cause. OSU researchers pair the emerging literature on groundwater...
