The presence and significance of salmon for prehistoric and aboriginal people of the Columbia Plateau is a matter of considerable debate among anthropologists, archaeologists and historians. Data from over 100 archaeological sites are scrutinized in the light of an example salmon fishery developed from ethnographic and archaeological information on aboriginal...
Pacific Northwest prairies have become significantly reduced in extent, and in the Willamette Valley of Oregon, less than one percent of native upland prairies remain. Many species have been impacted by this extreme loss of habitat, including Castilleja levisecta (golden paintbrush), a threatened hemiparasitic forb species endemic to the Pacific...
In this thesis, in order to understand why Buddhists in Southeast Asia protect rainforests and to establish a solid foundation for Buddhist environmental ethic, my first two tasks are to draw a clear picture regarding two major environmental concepts--nature and anthropocentrism--in Buddhism and to defend the claims that the Buddhist...
This thesis analyzes the emerging technology of hydraulic fracturing and shale gas extraction process through a pluralistic philosophical approach. Rather than defending traditional values in nature, such as intrinsic value, I defend a metaphilosophical pragmatism centered on policy implications. I argue that different philosophical positions will, most of the time,...
Using the historical range of forest conditions as a reference for managing landscapes has been proposed as a "coarse-filter" approach to biodiversity conservation. By emulating historical disturbance processes, it is thought that forest management can produce forest composition and structure similar to the conditions that once supported the native biota....
The 2002 Biscuit Fire burned through more than 200,000 ha of mixed conifer/
evergreen hardwood forests in southwestern Oregon and northwestern
California. The remarkable size of the fire and the diversity of conditions through
which it burned provided an opportunity to analyze the correlates of burn severity
across vegetation types...
National statistics indicate that over ten thousand persons
each year become disabled from spinal cord-injury. The need for
research in this area is evident.
The objectives of this study were:
1. To determine any relationship between selected attitudes
and activity levels with self-concept;
2. To identify certain demographic variables that...
The purpose of this study was to determine the accuracy of placing
adults in reading materials based on scores from a word-opposite test.
The population was randomly selected from students attending
developmental education classes at three Oregon community colleges.
The Word Opposite Reading Placement Instrument (WOPI) was derived
from a...
The central purpose of this study was to develop a model for
the examination of productivity in Adult Basic Education. To that
end, an instrument developed for use in the field of business was
adapted for use with an educational audience. It examined the

The purpose of the study was to determine if a self-assessment procedure provides data with acceptable accuracy for use in Adult Basic Education placement diagnostic batteries. Several factors descriptive of the population and the treatment were studied: 1. The overall degree of accuracy in computation and word pronunciation. 2. The...
Historically, brewers have used dry-hopping (a cold extraction of nonvolatile and volatile chemicals from hops into fermenting or finished beer) to increase the microbial stability and shelf life of their beer. As hoppy beer styles have gained in popularity over the last decade (2007-2017), the objective of dry-hopping has turned...
Across the U.S. social activism is on the upsurge, offering possibilities for a revolution against capitalism. However, these possibilities are potentially undermined by entrenched factionalism amongst the left. At root, such in-fighting is fostered by the creation of false dualistic frameworks on the transition out of capitalism and into the...
There have been years of stalled K-12 school finance reform efforts in Idaho, yet it was unclear what key Idaho education interest groups currently thought about how Idaho funds its public schools. Therefore, this project explored the institutional perspectives and beliefs of K-12 Idaho education stakeholders regarding the Idaho K-12...
Boron sprays produced fruit set increases in 'Barcelona'
hazelnut orchards in 1984 and in 1985. The absolute fruit set was
correlated with leaf B content but not with nut B. With relative
fruit set (RFS), B content of nuts in May (r = 0.63**) was more
strongly related to set...
The initial research question for this study asked whether single women were having their employment needs met by the union in a university setting. Twelve single women who were members of a union at a university participated in semi-structured interviews about their experiences with the union. To the surprise of...
Hypermediation, as described by Jay Bolter and Richard Grusin in their book Remediation, is a style of writing, recording, presenting, etc. that “makes us aware of the medium or media and (in sometimes subtle and sometimes obvious ways) reminds us of our desire for immediacy” (34). This mode of production...
Marine systems undergo changes in community composition over time as a result of a variety of environmental and anthropogenic factors. Understanding these community changes and the factors that drive them is critical for ecosystem management of marine resources. The Gulf of Alaska (GOA) is a large marine ecosystem that includes...
This thesis is comprised of two manuscripts that relate to forest-based management strategies in the context of market-based climate change mitigation policies. The work questions the appropriateness of a singular focus on carbon sequestration given the albedo effect and its possible countervailing climatic impacts. Through a review of salient literature...
Experiments were conducted to determine: (1) effects of pretransplant
stolon formation on performance of potato transplants in
the field and greenhouse; (2) effects of parent plant nodal position
on productivity of rooted nodal cuttings; and (3) relationships
between photoperiod and stolon formation.
The effects of early stolon formation on Russet...
The purpose of this thesis is to provide an overview of the use of solitary confinement and related techniques of isolation in juvenile correctional facilities in the United States. Given that scholars, correctional employees, incarcerated youth, and activists define solitary confinement in varied ways, this thesis attempts to synthesize those...
One of the basic questions facing transportation planners and road managers is how to provide and maintain a road system that provides efficient access to the forest while limiting adverse effects roads can have on water and soil resources. The purpose of this study is to develop decision support models...
In order to assess the importance of RNA synthesis in the induction
and antibody-producing phases of immune responses, actinomycin
D was used to inhibit the primary and secondary in vitro immune
responses of mouse spleen cells against heterologous erythrocytes.
The presence of actinomycin D (0.1 or 0.125 μg /ml) throughout...
Brushless Doubly Fed Machines (BDFM) have potential advantages in variable
speed generation and adjustable speed drive applications. The most significant of these
advantages is a reduction in the power electronic converter rating, and therefore a
reduction in overall system cost. Presently, efforts are being directed at optimizing the
design of...
The phenomenon of phantom limb pain has been well documented for centuries, but little clinical work has been done to alleviate it. Physician and neuroscientist Vilayanur S. Ramachandran began researching this condition nearly two decades ago, and has discovered a promising alternative treatment: mirror-box therapy. This therapy is not yet...
Civic participation has been perceived to be an important aspect in the City of Portland. Portland‟s civic engagement model and the high level of public participation from Portlanders have drawn praises. Not all communities, however, have been included in the democratic process, which should be accessible to all Portlanders. Communities...

I understand that my thesis
Price premiums and discounts are currently paid for various classes of wheat in the US marketplace. These premiums and the known heterogeneity of grain protein across landscapes beg the question of whether grain could be separated on the farm to maximize revenues. Theoretically, the concavity or convexity of a price...
Old-growth dry-mixed conifer forests are valued as habitats for late seral forest species, for the
ecosystem services and landscape diversity they provide, and for their aesthetic appeal. The
structure of these forests has been heavily altered by historic logging of overstory ponderosa
pine and Douglas-fir. Additionally, changes in fire regime...
This work examines the varied populations which have inhabited the South Fork region from prehistoric times to the present.
It disclosed that even though almost no archaeology has been done
in the area, data from contiguous regions suggest that persistent
and careful archaeological investigation should reveal valuable
and informative sites...
During years 2005, 2006, and 2007 ewes of predominantly Polypay breeding were bred to either Dorper or Polypay rams for spring lambing. Ewes were assigned to single-sire mating groups based on age and genotype. Internally generated replacements were added to the flock for the 2007 lambing season and bred to...
It has long been recognized by the legal community that when an immigrant seeks relief from deportation proceedings through the United States’ immigration courts, the proceedings they undertake are best seen as a game of chance depending on the Immigration Judge who is randomly assigned to their case. This thesis...
Habitat for wildlife species that depend on sagebrush ecosystems is of great management concern. Evaluating how management activities and climate change may affect the abundance of moderate and high-quality habitat necessitates the development of models that examine vegetation dynamics, but modeling tools for rangeland systems are limited. I developed state-and-transition...
It can be reasonably assumed that lamprey eel harvesting has systematically and periodically occurred along the Siletz River and its tributaries for as many hundreds, or thousands, or tens of thousands of years that human families and lamprey eel populations have coexisted in the Siletz Valley ecosystem. This report is...
• Premise of study: In the mixed evergreen forests in the western United States, Arbutus menziesii is able to quickly resprout following disturbance and, as such, act as a nurse tree during forest regeneration. The mechanism for this nurse tree effect has frequently been ascribed to mycorrhizal fungi, but no...
Lamprey eel harvesting has systematically and periodically occurred along the Siletz River and its tributaries for as many as hundreds, or thousands, or tens of thousands of years that human families and lamprey eel populations have coexisted in the Siletz Valley ecosystem. Historical, cultural, and biological information for the twentieth...
Widespread habitat degradation and uncharacteristic fire, insect, and disease outbreaks in forests across
the western United States have led to highly publicized calls to increase the pace and scale of forest restoration.
Despite these calls, we frequently lack a comprehensive understanding of forest restoration
needs. In this study we demonstrate...

Large-scale commercial thinning of young forests in the Pacific Northwest is currently promoted on public lands to accelerate the development of late-seral forest structure for the benefit of wildlife species such as northern spotted owls (Strix occidentalis caurina) and their prey, including the northern flying squirrel (Glaucomys sabrinus). Attempts to...
The influence of atmospheric humidity and free water on germination and germ tube growth of Botrytis cinerea Pers. ex Fr. was studied. Relative humidities (RH) were maintained inside insulated humidity chambers with sulfuric acid solutions of the appropriate concentrations. Insulation was necessary to reduce the incidence of condensation caused by...
Conservation of wildlife depends on an understanding of the interactions between animal movements and key landscape factors. Habitat requirements of wide-ranging species often vary spatially, but quantitative assessment of variation among replicated studies at multiple sites is rare. We investigated patterns of space use for 10 populations of two closely...
