Increasing temperatures in western North America are expected to result in a decline in winter snowpacks, earlier snowmelt, and a shift in the timing of streamflows, with an increasing fraction of streamflows occurring earlier in the water year and drier conditions during the summer. However, few streamflow datasets have associated...
The purpose of this study was to test the hypothesis that four-year
old children would better remember what happened in science
experiments, and the basic concepts involved in them, when presentation
of the experiments involved an element of surprise. Surprise
for this study was considered as a situation in which...
The process of biological nitrogen fixation involves the enzymic
reduction of atmospheric nitrogen (N₂) to ammonia (NH₃). The
enzyme which catalyzes this reduction, nitrogenase, does not exhibit
a high degree of substrate specificity. It also catalyzes the reduction
of acetylene (C₂2H₂) to ethylene (C₂H₄). The reduction of
C₂H₂ to C₂H₄...
PURPOSE/OBJECTIVE: Current theories of adaptation to disability do not address differences in adaptation to congenital compared to acquired disability. Although people with congenital disabilities are generally assumed to be better adapted than people with acquired disabilities, few studies have tested this, and even fewer have attempted to explain the mechanisms...
This dissertation investigates livelihood and land use change dynamics in a community at the farm-forest periphery in highland Ethiopia. I use interviews and livelihood assessment data to compare the strategies used by members of different wealth groups to negotiate and maintain access to forest resources, and integrate socioeconomic, bio-physical and...
The 158-year-old Commanding Officer's House at Fort Hoskins is one of only two such structures in Oregon representing the pre-Civil War era on the Western Frontier. From 1856-1861, it embodies a link in history between the prevailing ideology of western expansion and replication of Eastern cultural values into the frontier...
This thesis explores the use of Supplemental Nutrition Assistance Program (SNAP) benefits at the Corvallis and Albany, Oregon Farmers' Markets and its role in food access for SNAP participants. Utilizing a mixed-methods approach combining a farmers' market survey and household interviews, the study investigated who uses SNAP at the farmers'...
Students with disabilities are not being afforded the same access to sporting opportunities as their peers without disabilities. The purpose of this dissertation was to build on a foundation of information regarding collegiate adaptive sports through a Critical Disabilities Studies lens. Specific aims included: (1) identifying and describing intercollegiate, adaptive...
Techniques to measure vegetative maturity and dormancy
of deciduous nursery stock were investigated in red-osier
dogwood. Previous methods which were based on: survival
or tip dieback, change in level of ethylene production,
xylem water potential, and alteration of square wave traces
traces, provided no better indication of dormancy than did...
The primary foci of the study were to determine the relationships
among perceptual modality, temporality, and academic achievement,
and to develop implications for the academic counseling of
middle school students based on the findings.
The sample was composed of 613 students enrolled in Prineville
Junior High School. The Edmonds Learning...
