Bus Replacement Modeling And The Impacts Of Budget Constraints, Fleet Cost Variability, And Market Changes On Fleet Costs And Optimal Bus Replacement Age, A Case Study, Jesse Alexander Boudart

Dissertations and Theses

Overwhelming evidence throughout the literature has shown that bus overhead and maintenance (O&M) costs increase as buses age. This has implications toward a fleet manager's decision of when one should buy, use, or sell buses to minimize total fleet costs. Unfortunately, there are uncertain market conditions associated with bus fleets that cloud the manager's ability to make appropriate decisions. Using integer programming (IP), O&M trends and changing market conditions are integrated into a model to better analyze bus fleets. Due to recent budget constraints of transit agencies, needs for a bus fleet replacement model have arisen. King County in Washington …

The Pursuit Of Commerce: Agricultural Development In Western Oregon, 1825-1861, Cessna R. Smith

Dissertations and Theses

This thesis examines how the pursuit of commercial gain affected the development of agriculture in western Oregon's Willamette, Umpqua, and Rogue River Valleys. The period of study begins when the British owned Hudson's Bay Company began to farm land in and around Fort Vancouver in 1825, and ends in 1861--during the time when agrarian settlement was beginning to expand east of the Cascade Mountains. Given that agriculture in Oregon, as elsewhere, would eventually reach a standard of national development, and given that most of Oregon's immigrants arrived poor and lacked the farm implements needed for subsistence, the question this study …

Environmental stewardship is an important attribute for students and populations of all ages to have. This study looked at the effect of middle school students of a teacher who participated in a summer field ecology training program taking part in a long-term ecology project, and the impact of the experience on their environmental stewardship attitude. A variety of qualitative and quantitative techniques were used to look at changes in students' environmental stewardship attitudes including: surveying in a pre/post format, teacher, parent, and student focus groups, and teacher interviews. The teacher's experience with the summer field ecology training provided a foundation …

Beyul Khumbu: Sherpa Constructions Of A Sacred Landscape, Lindsay Ann Skog

Dissertations and Theses

Khumbu, part of Sagarmatha (Mt. Everest) National Park in eastern Nepal and an UNESCO World Heritage site, is home to the Sherpa people, ethnic Tibetan Buddhists who migrated to the region more than 500 years ago. Sherpas animate the landscape with localized water, tree, rock, and land spirits, identify sacred mountains, mainly associated with the Bönpo and Tibetan yullha traditions, and some view the landscape as a beyul, a sacred place and hidden valley protecting Buddhist people and beliefs in times of turmoil and need. These beliefs protect the natural environment through religious practices and taboos against environmentally harmful …

Examining The Effects Of Climate Change And Urban Development On Water Demand: A Multi-Scale Analysis Of Future Water Demand In Hillsboro, Oregon, Lily Arielle House-Peters

Dissertations and Theses

In the Portland, Oregon, metropolitan area, suburban cities such as Hillsboro are projected to grow as people seek affordable housing near a rapidly growing metropolis. This thesis examines the combined impact of climate change and urban development on both neighborhood and municipal scale residential water demand in Hillsboro, Oregon. I use two models, a surface energy balance model, Local-scale Urban Meteorological Parameterization Scheme (LUMPS), and a system dynamics model, CCDomestic, to investigate changes in residential water demand in the 2040s at two distinct spatial scales, the neighborhood and the municipality. I calibrate and validate each model to the reference period …

"Heaven's Last, Worst Gift To White Men": The Quadroons Of Antebellum New Orleans, Erin Elizabeth Mccullugh

Dissertations and Theses

Visitors to Antebellum New Orleans rarely failed to comment on the highly visible population of free persons of color, particularly the women. Light, but not white, the women who collectively became known as Quadroons enjoyed a degree of affluence and liberty largely unknown outside of Southeastern Louisiana. The Quadroons of New Orleans, however, suffered from neglect and misrepresentation in nineteenth and twentieth-century accounts.

Historians of slavery and southern black women, for example, have written at length on the sexual experiences of black women and white men. Most of the research, however, centers on the institutionalized rape, victimization, and exploitation of …

Portland's Independent Music Scene: The Formation Of Community Identities And Alternative Urban Cultural Landscapes, Rebecca Elizabeth Ball

Dissertations and Theses

Portland has a rich, active, and fluid music culture which is constantly being (re)created and (re)defined by a loose network of local musicians who write, record, produce, promote, distribute, and perform their music locally (and sometimes regionally, nationally, and internationally) and local residents, or audiences, who engage in local musical practices. Independent ("indie") local music making in Portland, which is embedded in DIY (do it yourself) values, creates alternative cultural places and landscapes in the city and is one medium through which some people represent themselves in the community. These residents not only perform, consume, promote, and distribute local music, …

Guild's Lake Courts : An Impermanent Housing Project, Tanya Lyn March

Dissertations and Theses

Guild's Lake Courts was built as temporary worker housing for the steel and shipyard industries during World War II. The massive housing development in Northwest Portland consisted of 2,432 units of housing, five community buildings, five childcare centers, a grade school and a fire station. Guild's Lake Courts was the eighth largest housing project built at that time in the United States. The peak population in January 1945 was approximately 10,000 individuals. Archival research, face-to-face oral histories, and resident reunions were used to explore the social, architectural and political history of Guild's Lake Courts. The lens for understanding how the …

Climatic And Spatial Variations Of Mount Rainier's Glaciers For The Last 12,000 Years, Michael Leslie Hekkers

Dissertations and Theses

Regional paleoclimatic proxies and current local climate variables and were analyzed to reconstruct paleoglaciers in an effort to assess glacier change On Mount Rainier. Despite the dry and generally warm conditions (sea surface temperatures (SST) -0.15°C to +1.8°C relative to current temperatures), the previously documented McNeeley II advance (10,900 - 9,950 cal yr B.P.) was likely produced by air temperature fluctuations. The average SST record and the terrestrial climate proxies show cooling temperatures with continued dryness between McNeeley II and the Burroughs Mountain advance (3,442 - 2,153 cal yr B.P.). The paleoclimate during the Burroughs Mountain advance was both cool …

A Beer Party And Watermelon: The Archaeology Of Community And Resistance At Ccc Camp Zigzag, Company 928, Zigzag, Oregon, 1933-1942, Janna Beth Tuck

Dissertations and Theses

In March 1933, the administration of United States President Franklin D. Roosevelt initiated a national relief program aimed at alleviating the disastrous effects ofthe Great Depression. The Civilian Conservation Corp (CCC) began as one of these programs designed to employ young men from all over the country and put them "back to work". The CCC provided these young men with training, a monthly stipend, and basic supplies such as food, clothing, and accommodations. After 1942, CCC camps were closed and many of these sites were abandoned or destroyed, leaving little historical documentation as to the experiences ofthe people involved. This …

Internal Displacement In Colombia: Violence, Resettlement, And Resistance, Juan Esteban Zea

Dissertations and Theses

The majority of the estimated four million internally displaced persons (IDPs) in Colombia who have fled from their lands and homes have migrated to urban centers. This study, performed in Bogotá, Colombia between April and September 2009, examines how IDPs cope with living in a new, urban environment after violent displacement. I held interviews with IDPs, the non-displaced public, and government workers; performed participant-observation in government offices and neighborhoods; and examined archival material. The work examines cultural anthropological topics of violence, migration, and resistance. A discussion of state and structural violence reveals the current hardships many rural Colombians face. Analysis …

The Effect Of The Study Region On Gis Models Of Species Geographic Distributions And Estimates Of Niche Evolution; Preliminary Tests With Montane Rodents (Genus Nephelomys) In Venezuela, Ali Raza

Dissertations and Theses

Various niche-based techniques exist to model a species' potential geographic distribution in a Geographic Information Systems (GIS) framework. These models compare the environmental conditions of localities of a species' occurrence versus those of the overall study region. In addition to uses in areas such as macroecology and conservation biology, this approach has been applied recently to studies of niche evolution and historical biogeography. Definition of the study region is critical for all of these applications but has not been addressed previously. Here, I examine the effect of changes in the extent of the study region on potential distribution models of …

Model Analysis Of The Hydrologic Response To Climate Change In The Upper Deschutes Basin, Oregon, Michael Scott Waibel

Dissertations and Theses

Considerable interest lies in understanding the hydrologic response to climate change in the upper Deschutes Basin, particularly as it relates to groundwater fed streams. Much of the precipitation occurring in the recharge zone falls as snow. Consequently, the timing of runoff and recharge depend on accumulation and melting of the snowpack. Numerical modeling can provide insights into evolving hydrologic system response for resource management consideration. A daily mass and energy balance model known as the Deep Percolation Model (DPM) was developed for the basin in the 1990s. This model uses spatially distributed data and is driven with daily climate data …

The Transnational Networks Of Cultural Commodities: Peruvian Food In San Francisco, Kelsey Ann Brain

Dissertations and Theses

In a setting of increased movement, communication, and flows across space, commodity chain networks bring valued cultural commodities to transnational communities. This research examines the networks bringing foreign cuisine ingredients to Peruvian transnational communities in San Francisco, California. It seeks to answer three inter-related questions: 1) What are the origins and transportation networks bringing Peruvian food items to San Francisco; 2) Who controls and benefits from the movement of this food and resulting capital; and 3) How do networks vary for different classes of end consumers?

Chefs of ten Peruvian restaurants and ten Peruvian migrants in the San Francisco area …

Community Development For A White City: Race Making, Improvementism, And The Cincinnati Race Riots And Anti-Abolition Riots Of 1829, 1836, And 1841, Silas Niobeh Crowfoot

Dissertations and Theses

This project is an historical ethnography and a cultural history of the anti-black race riots and anti-abolition riots in Cincinnati, Ohio, in 1829, 1836, and 1841. It is also a case history in an urban and commercial/early industrial context of the idea that violent social practices such as riots, as well as law and the customary practices of everyday living, are deployed as race making technologies, actually constructing racial categories. By extending this constructivist concept to the conversion of space to place through the human ascription of meaning, this study also examines racial violence as a strategy for place making …

American Belly Dance And The Invention Of The New Exotic: Orientalism, Feminism, And Popular Culture, Jennifer Lynn Haynes-Clark

Dissertations and Theses

Belly dance classes have become increasingly popular in recent decades in the United States. Many of the predominantly white, middle-class American women who belly dance proclaim that it is a source of feminist identity and empowerment that brings deeper meaning to their lives. American practitioners of this art form commonly explain that it originated from ritual-based dances of ancient Middle Eastern cultures and regard their participation as a link in a continuous lineage of female dancers. In contrast to the stigmatization and marginalization of public dance performers in the Middle East today, the favorable meaning that American dancers attribute to …

Use Of Media Technologies By Native American Teens And Young Adults: Evaluating Their Utility For Designing Culturally-Appropriate Sexual Health Interventions Targeting Native Youth In The Pacific Northwest, Stephanie Nicole Craig Rushing

Dissertations and Theses

American Indian and Alaska Native (AI/AN) youth are disproportionally burdened by high rates of sexually transmitted infections and teen pregnancy, heightening their need for sexual health interventions that are aligned to their unique culture and social context. Media technologies, including the Internet, cell phones, and video games, offer new avenues for reaching adolescents on a wide range of sensitive health topics. While several studies have informed the development of technology-based interventions targeting mainstream youth, no such data have been reported for AI/AN youth. To fill this gap, I: a) quantified media technology use in a select group of AI/AN teens …

Coal To Oil In China: Scientific Development Or Crossing The River By Feeling The Stones?, Joseph John Narus

Dissertations and Theses

Since the start of the 21st century, energy security concerns and rising international energy costs have led China to pursue the development of a coal to oil industry, whereby converting a portion of the nation's abundant coal reserves into gasoline, diesel, or jet fuel, China might be able to increase its domestic oil production and generate profits. But a large-scale coal to oil industry exerts added pressure on China's domestic coal reserves and water resources, and generates significant greenhouse gas emissions. The tension between the potential benefits of coal to oil development and its associated negative externalities present a challenge …

Hierarchical Image Analysis And Characterization Of Scaling Effects In Remote Sensing, Craig David Ducey

Dissertations and Theses

The effects of scale influence all aspects of spatial analysis and should be expressly considered early in research planning. Remotely sensed images provide unique landscape perspectives and possess several features amenable to dealing with scale. In particular, images can be segmented into image objects representative of landscape features and structured as nested hierarchies for evaluating landscape patterns across a range of scales. The objectives of this research are to evaluate methods for: 1) characterizing candidate image objects to inform the selection of user-supplied segmentation parameters and 2) exploring the multi-scale structure of landscape patterns for defining and describing potentially important …

Local Food And Land-Use In Washington County, Oregon, Joshua James Cousins

Dissertations and Theses

Local food networks are often defined as presenting a variety of alternative food production, consumption, and distribution practices to the conventional food system such as community-supported-agriculture, farmers markets, and community gardens. Local food initiatives are commonly proposed as a model for the future of sustainable agriculture, and in the region of Portland, Oregon the abundance of such alternative venues results from the area's natural surroundings and smart planning. The region is host to 39 farmers markets and Portland is often hailed as one of the country's most sustainable cities. This study examines the role of local food networks in preserving …

Working For The "Working River": Willamette River Water Pollution, 1926 To 1962, James Vincent Hillegas

Dissertations and Theses

Efforts to abate Willamette River pollution between 1926 and 1962 centered on a struggle between abatement advocates and the two primary polluters in the watershed, the City of Portland and the pulp and paper industry. Throughout the twentieth century, the Willamette was by far the most heavily populated and industrialized watershed in Oregon. Like many other of the world's rivers, the Willamette was an integral part of municipal and industrial waste removal systems. As such, the main stem of the river carried the combined wastes from sewage outfalls serving hundreds of thousands of people and millions of gallons daily of …

Phylogeographic And Phylogenetic Exploration Of Plethodon (Plethodontidae, Caudata) Salamanders In The Pacific Northwest, Tara Anne Pelletier

Dissertations and Theses

Genetic studies of amphibians often reveal substantial population structure due to either historical demographics from changing climate and geographic features over varying timeframes. Eight species of terrestrial salamanders (Family: Plethodontidae, Genus: Plethodon) reside in forests of the Pacific Northwest (PNW). Plethodon vehiculum is the most widespread and abundant terrestrial salamander in the PNW yet evolutionary studies are lacking. Using mitochondrial DNA (mtDNA) sequence data (D-loop and cytb) questions regarding the phylogeography of P. vehiculum and phylogenetics of western Plethodons are explored. Two major clades were defined in P. vehiculum, a southern clade in the Klamath-Siskiyou region and a …

Impacts Of Climate Change And Urban Development On Water Resources In The Tualatin River Basin, Sarah Praskievicz

Dissertations and Theses

Potential impacts of climate change on the water resources of the Pacific Northwest of the United States include earlier peak runoff, reduced summer flows, and increased winter flooding. An increase in impervious surfaces, accompanied by urban development, is known to decrease infiltration and increase surface runoff. Alterations of flow amount and pathways can alter water quality through dilution or flushing effects. I used the United States Environmental Protection Agency's Better Assessment Science Integrating Point and Nonpoint Sources (BASINS) modeling system to investigate the relative importance of future climate change and land use change in determining the quantity and quality of …

Ethnic Place Making: Thirty Years Of Brazilian Immigration To South Framingham, Massachusetts, Laura Aldea Skorczeski

Dissertations and Theses

Over the past thirty years, Massachusetts has become a hub of Brazilian immigration. Within Massachusetts, the town of Framingham has the highest concentration of Brazilian residents; one census tract in the southern part of this Boston suburb is an astounding 57.4 percent Brazilian. The presence of the Brazilian population in downtown Framingham, also referred to as South Framingham, has transformed the area into a landscape of Brazilian ethnicity.

When Brazilians began arriving in South Framingham in the early 1980s, the downtown Central Business District was a blighted landscape. This thesis analyzes how Brazilian identities have become imprinted on the landscape …

Sex Work And Moral Conflict: Enhancing The Quality Of Public Discourse Using Photovoice Method, Crystal Renee Tenty

Dissertations and Theses

This thesis uses an advocacy/participatory framework and moral conflict theory to examine the opposing ideas: and interests of parties involved in the issue of prostitution on 82^nd Avenue in Portland, Oregon. It locates areas of contention within the larger dominant feminist discourse, which views sex work as either a form of violence and exploitation or as a form of legitimate free-contract labor. The thesis shows how the intractable moral conflict between these differing feminist theories and values can be mediated using participatory data collection techniques.

Ethnographic data was collected and analyzed from 11 women working in the sex industry …

The study focuses on green building and buying programs.

This is an exploratory study aimed at determining if detailed information, recommended for pursuit by Portney (2003), is available regarding: (a) how individual city sustainability programs got started; (b) how they maintain or fail to maintain themselves; (c) what they have been able to achieve programmatically; and (d) how effectively they have accomplished environmental …

Multi-Level Environmental Governance : A Comparative Case Study Of Five Large Scale Natural Resource Management Programs, Shpresa Halimi

Dissertations and Theses

Globalization is occurring at an unprecedented pace through the end of the twentieth century and into the new millennium. In such a world, governance is increasingly shared among governments, civil society organizations and businesses. Globalization has placed new demands on environmental management across national borders. Hence, changes in the environmental governance frameworks are required to create the enabling conditions for the effective management of the natural resources and the environment.

This study seeks to develop an integrated "Multi-level Environmental Governance" (MLEG) framework and to explore the relationship between the core characteristics of the framework and the achievements of large scale …

Physicians Providing Alternative Medicine: Boundary Crossing And The Emergence Of Integrative Medicine, Richard Scott Lockwood

Dissertations and Theses

Integrative medicine (IM) has organized as a new area of specialization in mainstream healthcare. The development of IM is widely attributed to popular demand for the range of therapies known collectively as Complementary and Alternative Medicine (CAM). During the 1990's the rate of acceptance of CAM accelerated among consumers, professions, financing and education. The Medical Expenditure Panel Survey (MEPS) measured CAM utilization and professional service provision during the years 1996 and 1998, but never since. These surveys were unique because they specifically inquired as to whether CAM was provided by a physician, among other types of professionals. This dissertation defines …
