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...
This study describes and analyzes Oregon Trail related
exhibits of eleven museums and two interpretive centers
that are geographically located along the Oregon Trail
from Baker City, Oregon to Portland, Oregon. The exhibits
were featured at the facilities during the 1993 Oregon
Trail Sesquicentennial, a celebration that was initiated
and...
Over the last 25 years structural adjustment programs have challenged Ecuador's ability to provide adequate social services and employment opportunities. In the wake of these policies, many women have turned to non-governmental agencies for possible solutions and assistance. Empowerment programs as a form of development work in particular have been...
Micronesians are in the process of becoming independent nation-states after nearly a
century of colonial rule, including four decades of U.S. administration as the Trust
Territory of the Pacific Islands. Pressures to attain self-sufficiency have led many of these
island nations to embrace tourism as an economic development strategy. Meanwhile,...
As dams approach the end of their useful life, there is need to predict where and how accumulated sediment will move following their removal to estimate impacts on aquatic habitat and infrastructure. Flume studies suggest that sediment pulses disperse in place for most dams, but it is hypothesized that a...
Ungulate behavior has been studied extensively but direct observation of free-ranging animals over long periods of time and large geographic areas is often prohibitively difficult. Improved technology, such as GPS collars fitted with motion-sensitive activity monitors, provides researchers with a potential tool to remotely collect fine scale activity and location...
This thesis examines the concepts of power and participation and how they are intertwined in the examination of the urban planning systems in Curitiba, Brazil. Power is identified as both the planning system's ability to affect the daily lives of the city's residents and the power of individuals and groups...
The purpose of this annotated bibliography is to guide middle school and high school students into critical thinking about environmental issues. Through keen observation of their bioregion and through an integration of interdisciplinary literature which focuses on Oregon writers, students will be challenged to think, write, and discuss current issues...
Seeding is a vital tool to facilitate recovery of degraded ecosystems, but low seedling recruitment rates limit the utility of this practice in a range of ecosystems across the globe. Plant functional traits impact individual fitness through effects on growth, reproduction and survival. Consequently, seed and seedling trait variation among...
Groundwater nitrate contamination is a well-documented issue in the Southern Willamette Valley (SWV) of Oregon, as a Groundwater Management Area (GWMA) has recently been declared. As a GWMA, groundwater nitrate monitoring must occur until regional concentrations are below 7 mg/L NO3-N. However, the presence of temporal variability can make it...
Coho salmon (Oncorhynchus kisutch) migration and spawning are unique components of the salmon life cycle because they require synchrony of behavior with other individuals as well as with acceptable fluvial conditions. As with other organisms that exhibit group mating behavior, it is likely that environmental cues trigger coho salmon movement...
The purpose of this thesis is to understand the experiences that Nahua children, in rural Mexico, have as they attend schools that are primarily influenced by formal Western education in relation to their own ways of learning and knowing. This research took place over the course of three months within...
Ocean acidification (OA) is the result of increasing concentrations of anthropogenic carbon dioxide (CO₂) emissions, leading to a suite of alterations to specific parameters of ocean chemistry, which can negatively impact many marine organisms and ecosystems. Understanding how to measure and monitor the chemistry of OA will require specialized education...
Despite advances in the understanding of rain-on-snow storms and their resulting peak flows, little is understood about the response of snowmelt to precipitation and the relative timing of the two at multiple temporal scales within such events. To address this issue, climate, snowmelt, and streamflow data were analyzed for 26...
The Valley of Oaxaca, Mexico was home to one of the most intensively-studied archaic states in the New World. Centered at the hilltop city of Monte Albán, the Zapotec State first arose around 500 BC and eventually encompassed much of the present-day state of Oaxaca. But by the Late Classic...
This thesis examines two neighborhood emergency preparedness programs: the Linn-Benton Neighborhood Emergency Training (LB NET) program in Corvallis, Oregon, U.S.A., and the Women's Neighborhood Networking Program (WNNP) in Uzhhorod, Ukraine. In Corvallis, the LB NET began in 1996, in part out of concerns that in a large disaster the local...
