Silicic Volcanism At The Northern And Western Extent Of The Columbia River Basalt Rhyolite Flare-Up: Rhyolites Of Buchanan Volcanic Complex And Dooley Mountain Volcanic Complex, Oregon, Adam M. Large

Dissertations and Theses

Two mid-Miocene (16.5-15 Ma) rhyolite volcanic centers in eastern Oregon, the Buchanan rhyolite complex and Dooley Mountain rhyolite complex, were investigated to characterize eruptive units through field and laboratory analysis. Results of petrographic and geochemical analysis add to field observations to differentiate and discriminate the eruptive units. Additionally, new geochemical data are used to correlate stratigraphically younger and older basalt and ash-flow tuff units with regional eruptive units to constrain the eruptive periods with modern Ar-Ar age dates.

Previous work at the Buchanan rhyolite complex was limited to regional mapping (Piper et al., 1939; Greene et al., 1972) and brief …

Groundwater-Surface Water Interactions Near Mosier, Oregon, Cullen Brandon Jones

Dissertations and Theses

The town of Mosier, Oregon, is located near the east, dry end of the Columbia River Gorge, and the local area is known for cherry orchards that rely heavily on groundwater for irrigation. The CRBG groundwater system in Mosier has experienced groundwater declines of up to 60 meters due to over-pumping and or commingling. Declining groundwater levels have led to concerns over the sustainability of the resource, as it is the principle water source for irrigation and domestic use. Despite numerous previous studies of groundwater flow in CRBG aquifers here and elsewhere in the Columbia River basin, an aspect that …

Do Forest Commons Contribute To International Environmental Initiatives? A Socio-Ecological Analysis Of Nepalese Forest Commons In View Of Redd+, Harisharan Luintel

Dissertations and Theses

Forests in developing countries have the potential to contribute to global efforts to mitigate climate change, promote biodiversity and support the livelihoods of rural, local people. Approximately one-fourth of such forests are under the control of local communities, which primarily manage forests for subsistence and to meet their livelihood needs. The trend of bottom-up community control is increasing through the adoption of decentralization reforms over the last 40 years. In contrast, the United Nations has introduced the top-down program, Reducing Emissions from Deforestation and Forest Degradation (REDD+) for the conservation and enhancement of forest carbon and the sustainable management of …

Japanese Dialect Ideology From Meiji To The Present, Nao Okumura

Dissertations and Theses

The intent of this study is to examine the trajectory of ideology regarding standard Japanese and dialects from the historical perspective, and also to discuss the cause of the post-war shift of the ideology. Before the war, the government attempted to disseminate hyojun-go aiming at creating a unified Japan in the time when many countries were developing to be nation states after industrial revolution. After the Pacific war, the less strict-sounding term kyotsu-go was more often used, conveying an ideology of democratization. Yet despite the difference in the terms, speaking a common language continues to play a role of unifying …

Biofouling Management In The Pacific Northwest And Predation On Native Versus Non-Native Ascidians, Erin Suzanne Kincaid

Dissertations and Theses

Marine non-native species threaten economic and environmental health, making it crucial to understand factors that make them successful. Research on these species, therefore, allows for greater preparedness and informed management of biological invasions and increases understanding of elements structuring biological communities. Among the marine non-native species, and particularly the fouling community, non-native ascidians are a taxon of particular concern because they can crowd out native benthic species and smother mariculture products. This thesis addresses management for ascidians and other fouling organisms and includes research on the invasiveness of this taxon in addition to the invasibility of recipient fouling communities. On …

On Both Sides Of The Tracks: Light Rail And Gentrification In Portland, Oregon, Nathan Eric Rochester

Dissertations and Theses

This study draws on census data and geographic information systems (GIS) to investigate the relationship between light rail transit (LRT) infrastructure development and gentrification in Portland, Oregon. While recent research using comprehensive measures of neighborhood socioeconomic status (SES) supports a potentially causal link between transit development and gentrification, research into the effects of transit on property values alone tends to dominate the discourse. This study therefore seeks to build on previous research to develop an index measure of neighborhood SES and SES change based on measures of education, occupation, and income, using census data from 1980-2010. This multifaceted measure of …

Stranding Mortality Patterns In California Sea Lions And Steller Sea Lions In Oregon And Southern Washington, 2006 To 2014, Kessina Lee

Dissertations and Theses

As changing ocean conditions lead to declining fish stocks and movement of forage fish, sea lions on the Oregon coast are subject to the pressures of declining prey availability and increasing conflicts with commercial and recreational fisheries. An analysis of strandings of California sea lions, Zalophus californianus, and Steller sea lions, Eumetopias jubatus, from 2006 to 2014, included cause of death, changing ocean conditions, and anthropogenic activity. Causes of death included disease, injury, and human interaction, such as gunshot wounds, fisheries net entanglements and boat strikes.

Oregon and Washington strandings of California sea lions are primarily adult and …

Factors Driving The Concentration Of Ephemeral Flow, Gretchen Anne Guyer

Dissertations and Theses

In spite of decades of related research, stream channel initiation is still not well understood. Current theories of channel initiation are grounded in research conducted by Montgomery and Dietrich, largely in the transport limited, temperate, humid climate of the Pacific Northwest, USA. This field data driven work concluded that the drainage area required for channel initiation is directly correlated to the slope of the contributing area. However, there are a host of related variables that have yet to be examined in the field. This study revisits the slope-area relationship focusing on ephemeral overland flow in headwaters of both the Pacific …

The "Adam Cube" : Categorizing Portland, Oregon's Urbanization Using Gis And Spatial Statistics, Jeremy Grotbo

Dissertations and Theses

Transportation availability and land use intensity demonstrate a strong relationship, with intense development concentrated near significant transportation investment. Transportation networks evolved in response to emergent transportation technologies and changing urban land uses. The irregular distribution of transportation systems reinforced patterns of land use development, shaping urban form. Understanding the relationships between transportation and the intensity of land uses allows urban geographers and city planners to explain the urbanization processes, as well as to identify areas historically susceptible to future development. The goal of this research is to develop a quantitative framework for the analysis of the development of urban form …

On The Variability Of Pacific Ocean Tides At Seasonal To Decadal Time Scales: Observed Vs Modelled, Adam Thomas Devlin

Dissertations and Theses

Ocean tides worldwide have exhibited secular changes in the past century, simultaneous with a global secular rise in mean sea level (MSL). The combination of these two factors contributes to higher water levels, and may increase threats to coastal regions and populations over the next century. Equally as important as these long-term changes are the short-term fluctuations in sea levels and tidal properties. These fluctuations may interact to yield locally extreme water level events, especially when combined with storm surge. This study, presented in three parts, examines the relationships between tidal anomalies and MSL anomalies on yearly and monthly timescales, …

Is Scholarship Advancing?: An Analysis Of Fifteen Years Of Framing Research, Joseph Zachary Provencher

Dissertations and Theses

In 2011, Porismita Borah published "Conceptual Issues in Framing Theory: A Systematic Examination of a Decade’s Literature" to shed light on the status of framing research, and attempt to answer several scholars' criticisms of framing research practices (Carragee and Roefs 2004, D'Angelo, 2002, Entman, 1993). Borah argues that framing research has several areas of necessary improvement, and her prescription is for future research to be able to examine specific framing issues or effects, but also be able to connect with broader understandings of framing.

The following content analysis of framing research, conducted between the year 2000 and 2013, seeks to …

Assessing Sense Of Place And Geo-Literacy Indicators As Learning Outcomes Of An International Teacher Professional Development Program, Nancee Hunter

Dissertations and Theses

This research explores the multifaceted benefits that accrue from learning within an international, experiential context. It uses a qualitative, case study approach employing pre and post surveys, in-situ observations, and semi-structured photo-elicitation interviews to analyze the Center for Geography Education in Oregon’s (C-GEO) 2013 Overseas Teacher Institute--a professional development program that took 11 teachers to Russia, Mongolia, and China for a total of 17 days (plus two additional travel days) to learn about the cultural and physical geography of each place. The focus of the research is two-fold and examines processes involved in gaining, synthesizing and applying 1) a sense …

Travel Mode Choice Framework Incorporating Realistic Bike And Walk Routes, Joseph Broach

Dissertations and Theses

For a number of reasons--congestion, public health, greenhouse gas emissions, energy use, demographic shifts, and community livability to name a few--the importance of walking and bicycling as transportation options will only continue to increase. Currently, policy interest and infrastructure funding for nonmotorized modes far outstrip our ability to model bike and walk travel. To ensure scarce resources are used most effectively, accurate models sensitive to key policy variables are needed to support long-range planning and project evaluation, and to continue adding to our growing understanding of key factors driving walk and bike behavior. This research attempts to synthesize and advance …

Phylogeography Of Two Species Of The Genus Apochthonius Chamberlin, 1929, In The Pacific Northwest (Arachnida, Pseudoscorpiones), Brandi Lynn Welch

Dissertations and Theses

I used mitochondrial COI sequence data from forty one individuals to investigate phylogenetic relationships among populations of two morphologically similar species of the pseudoscorpion genus Apochthonius, A. minimus and A. occidentalis, in western Washington, Oregon, and northern California. My goal was to assess whether genetic structure in the two species was congruent with geography. Many plant and animal species in the Pacific Northwestern United States have shown patterns of genetic differentiation that follow both north-south and east-west trends, indicating that geologic and climatic events in the past separated populations to the extent that they became genetically differentiated. A distinct geographic …

Maternal Mortality: A Policy Comparison Between Nigeria And India., Rachel Quarles

Dissertations and Theses

A staggering number of women die from preventable deaths each year from causes related to pregnancy and childbirth. India hosts the greatest number of actual maternal deaths in the world, although Nigeria’s ratio of maternal deaths to live births is greater than India’s. This thesis focuses on the experience of these two countries in order to determine if India’s governmental policies, level of government corruption, and traditional practices directly lead to its comparably better maternal health statistics. India has demonstrated lower ratios of maternal mortality and more consistent improvement in maternal health indicators than Nigeria as a result of stronger …

The Incongruence Of Development Assistance: An Overview Of World Bank Policies, Elizabeth Garcia-Polanco

Dissertations and Theses

In post-conflict countries were instability has intensified, it becomes apparent how inadequate development assistance can be and why even after large sum of investments development assistance has not been able to completely alleviate poverty. For agencies like the World Bank that provide first hand assistance, we question whether there are prerequisites needed in order for their policies to be effective and whether these policies are targeting the core reasons for the countries’ poverty dilemma. African countries continue to hold intricate predicaments that may at times be too complicated to be analyzed without sufficient resources provided by the international community. While …

Globalization, Tourism And Sustainable Development: The Multifaceted Impact Of Tourism On Development And Poverty Alleviation In Brazil, Gaëlle Lopes Saraiva

Dissertations and Theses

Globalization is a popular concept deeply embedded in our era that represents the widespread intensification of transnational connections emblematic of this century. In general, this study aims to clarify the contradictory effects globalization exerts on development by specifically analyzing the particular impact of tourism in the emerging economy of Brazil. It is argued that the unequal distribution of tourism activities between urban and rural areas, and the prevalence of specific sizes and types of tourism are the main factors involved in sustaining unequal patterns of development across the country. The study concludes that public-private partnerships in tourism should prioritize the …

Health, Education And Children’S Rights: A Comparability Analysis Of Kenya And Brazil, Charlette Lopez

Dissertations and Theses

Developing adequate health care and education systems has been an ongoing struggle for the governments of both Kenya and Brazil. Despite moderate improvements in health and education statistics for both of these countries, there is clear evidence that these states will have to be actively engaged in order to overcome the challenges that lie ahead. Kenya and Brazil may differ in geographical location, history, culture, and socioeconomic status, but both countries are congruent in the challenges they face to provide sufficient access to quality health care and educational resources to the upcoming generations of children who are being failed by …

Change And Continuity: Turkish Foreign Policy Since 2002, Under The Justice And Development Party (Adalet Ve Kalkinma Partisi - Akp), Ustun Yuksel

Dissertations and Theses

This thesis analyzes the changes and continuity within Turkish foreign policy since 2002, under the Justice and Development Party (Adalet ve Kalkinma Partisi - AKP). In order to understand modern Turkish politics, it is important to realize Turkey’s aspirations of becoming a full member of the European Union and its subsequent push for strategic alliances with the Middle East and former Turkic republics from the Soviet Union. The evidence shows that Turkey has consistently strived to improve its relationship with the EU in its effort to become a full member state, but the EU’s reluctance to accept Turkey as an …

Desecularization Of The State As A Resistance To The Globalization: A Case Study Of The Criminalization Of Blasphemy In Russia., Artem Profis

Dissertations and Theses

A cultural aspect of westernization remains in the shadow of widely discussed economic and political ones. While many states are conforming to the Western rules of the global market game, the cultural characteristics and differences are less mutable and thus less easily compromised and resolved than political and economic ones. The dissolution of the U.S.S.R. has left behind a void in the Russian identity. After unsuccessful attempts to assume a Western liberal identity during the first half of the 90s, Russia has opted for tried and tested Orthodox Christianity to fill that void and to form a new post-Soviet Russian …

A Genetic And Biochemical Analysis Of Sulfolobus Spindle-Shaped Virus 1, Eric Alexander Iverson

Dissertations and Theses

Viruses infecting the Archaea exhibit a tremendous amount of morphological and genetic diversity. This is especially true for crenarchaeal viruses from the family Fuselloviridae, which possess spindle-shaped capsids and genomes that harbor a great number of uncharacterized genes. The functions of these unidentified gene products are of interest as they have the potential to provide valuable insights into the fusellovirus infection cycle and archaeal viruses in general. In an effort to better characterize the genetic requirements of the Fuselloviridae, we have performed genetic and biochemical experiments using the best studied fusellovirus, Sulfolobus spindle-shaped virus 1 (SSV1).

Using Landsat Tm Imagery To Monitor Vegetation Change Following Flow Restoration To The Lower Owens River, California, Lesley Crandell Bross

Dissertations and Theses

Rehabilitating river corridors to restore valuable riparian habitat consumes significant resources from both governments and private companies. Given these considerable expenditures, it is important to monitor the progress of such projects. This study evaluated the utility of using Landsat Thematic Mapper remotely-sensed data from 2002 and 2009 to monitor vegetation change induced by instream flow restoration to the Lower Owens River in central California. This study compared the results of an unsupervised classification with an NDVI threshold classification to appraise the resources required and effectiveness of each analysis method. The results were inspected by creating standard remote sensing accuracy error …

Coyotes On The Web: Understanding Human-Coyote Interaction And Online Education Using Citizen Science, Zuriel Anne Rasmussen

Dissertations and Theses

Coyote (Canis latrans) numbers are increasing in urban areas, leading to more frequent human-coyote interactions. Rarely, and particularly when coyotes have become habituated to humans, conflicts occur. Effective education about urban coyotes and how to prevent habituation reduces conflict. Citizen science, in the form of online education, can be used to engage and educate city dwellers about urban coyotes. In this research, I explore Portland Metropolitan Area (PMA) residents' baseline experiences with, and attitudes toward, urban coyotes. Next, I investigate citizen science as a tool for education. Using the Portland Urban Coyote Project (PUCP), a citizen science project, as a …
