The Making Of Seaside’S “Indian Place”: Contested And Enduring Native Spaces On The Nineteenth Century Oregon Coast, Douglas Deur

Anthropology Faculty Publications and Presentations

During the mid nineteenth century, non-Native settlement and activities disrupted and changed historic Chinook and Clatsop communities at the mouth of the Columbia River. Indian Place in what would be Seaside, Oregon, became home to a number of displaced peoples and an enclave where “the living gathered with the remains of the dead,” for “modest protection from the apocalyptic changes that so radically disrupted tribal lands, lives, and worldviews.” Douglas Deur documents tribal migration to the Indian Place during the late nineteenth and early twentieth centuries and calls attention to many of its significant early residents. Transitional communities such as …

Do Characteristics Of Walkable Environments Support Bicycling? Toward A Definition Of Bicycle-Supported Development, Christopher D. Muhs, Kelly Clifton

Civil and Environmental Engineering Faculty Publications and Presentations

Does walkability equate with bikeability? Through a comprehensive review of studies of the built environment and bicycling, including mode choice, route choice, safety, and urban design literature, this paper addresses this question. Previous work has raised the issue that the two modes are functionally different, despite them often being combined into a nonmotorized category, and has highlighted research challenges. Existing studies of bikeability have largely focused on infrastructure. This paper contributes to the literature on bicycling and the built environment by providing a thorough review of past research with a focus on the relationships between land use, urban form, and …

Resident Perceptions Of Natural Resources Between Cities And Across Scales In The Pacific Northwest, Anita T. Morzillo, Betty J. Kreakie, Noelwah R. Netusil, J. Alan Yeakley

Environmental Science and Management Faculty Publications and Presentations

As the global population becomes increasingly urban, research is needed to explore how local culture, land use, and policy will influence urban natural resource management. We used a broad-scale comparative approach and survey of residents within the Portland (Oregon)-Vancouver (Washington) metropolitan areas, USA, two states with similar geographical and ecological characteristics, but different approaches to land-use planning, to explore resident perceptions about natural resources at three scales of analysis: property level (“at or near my house”), neighborhood (“within a 20-minute walk from my house”), and metro level (“across the metro area”). At the metro-level scale, nonmetric multidimensional scaling revealed that …

Trans* Folks In Motion: Transgender And Gender Nonconforming Individuals' Experiences Of Transit And Transit Spaces, Jade Benner

University Honors Theses

Research on the experiences of transgender and gender nonconforming individuals is increasing, and this qualitative sociological study aims to build an understanding of trans* experiences on public transit and their experiences in the unique form of public space the confined space of the city bus and light rail train. I seek to amplify trans* voices, inform trans-inclusive transit policy, and add to conversations on how gender operates in urban and public spaces by contributing perspectives of transgender and nonbinary individuals.

From Protest To Press: An Examination Of Paradigmatic Changes In News Making And Their Effects On Social Movement Evolution, Melinda Guillen

University Honors Theses

In discussions of the expansion of the new media environment in journalistic endeavors, academics have begun focusing on how this expansion affects social protest movements' interaction and successful interaction with news making. The manner in which news is created and reaches the masses has adapted, sometimes reluctantly, to the explosion of new media communication technologies. One controversial issue has been the impact the contemporary media environment has made on social movements, specifically with protests. Researchers argue that the contemporary media environment has been a tool used by protests to partake in more effective information diffusion to the masses. This paper …

The Politics Of Water In Mexico City, Richelle Van Dusen

University Honors Theses

The privatization of water in the Mexico City Metropolitan Area is a long and complex process that continues today. The city’s greatest privatization effort, the National Water Law of 1992, was imposed by the federal government with assurances of improvement in accessibility, quality and sustainability. The resulting system that exists today has been largely ineffective in achieving these initial goals. Despite some progress in infrastructure, the partially-private system has aggravated the very social inequalities it aimed to alleviate, further marginalizing the poorest citizens through their water’s high costs, far-reaching inaccessibility, and poor quality. In the decentralized water system, contradictions become …

Comparing Unmanned Aerial Systems (Uas) Structure-From-Motion Digital Surface Modeling To Laser Imaging Detection And Ranging (Lidar), Joshua D. Schane

Geography Masters Research Papers

UAS (unmanned-aerial systems) mapping is an emerging technology in spatial science. UAS, more informally referred to as “drones,” are small, radio-controlled or autonomous aerial platforms outfitted with camera sensor systems that can be deployed to fly missions for mapping terrain and structures. With the use of a photogrammetry technique called structure-from-motion, overlapping aerial images can be developed into high-resolution spatial data (< 5-cm). These data are georeferenced by GPS location information assigned to aerial targets which act as ground-control points (GCPs). This research explores the accuracy of the UAS-derived digital surface model (DSM) as it relates to a LIDAR DSM of the same study area in St. Helens, Oregon.

The site that was chosen to be mapped was a large wastewater treatment plant, with surrounding natural areas, residential, and industrial properties. The site was mapped using a small quadcopter-style UAS which was programmed autonomously; the overlapping aerial …

The Conflict Resolution Case Study In Urban Life: Bull Run Watershed Case, Chang-Yu Hong

Geography Faculty Publications and Presentations

The City of Portland and the United States Department of Agriculture (USDA) Forest Service are working together, along with citizens, to formulate a comprehensive new policy to guide joint management of the Bull Run watershed at Mt. Hood National Forest. This process has brought about four decades of conflict, resulting from differences between the federal view of multiple use and the local view of exclusive use for producing high quality water. The new policy is being formulated by the City of Portland and the Forest Service through negotiation of a comprehensive Memorandum of Understanding that structures the parties’ roles, responsibilities, …

Re-Envisioning Macro Social Work Practice, Bowen Mcbeath

School of Social Work Faculty Publications and Presentations

This article presents 10 recommendations supporting a re-envisioning of macro practice for the 21^st century. These strategies are needed to counter a generational trend of disinvestment in macro social work practice and to support the historic vision of the social work profession as equally responsive to the needs of at-risk, disadvantaged populations and the organizational, community, and policy roots of social injustice. Before describing these recommendations and discussing their implications for the social work profession, I first briefly review the challenges facing macro practice and current initiatives promoting its renewal. The goal of this analysis is to define the …

Beyond The Screen: Uneven Geographies, Digital Labour, And The City Of Cognitive-Cultural Capitalism, Dillon Mahmoudi, Anthony M. Levenda

Urban Studies and Planning Faculty Publications and Presentations

In this paper, we demonstrate that an examination of the socio-environmental impacts of digital ICTs remains a fruitless enterprise without “materializing” digital labour. We suggest one approach to materializing digital labour: this first includes connecting political economic analyses of digital ICTs to the co-evolution and geography of planetary urbanization and technological change, and second, examining the relationships between immaterial, digital, labour with the material industrial production system. In the context of broad changes in technology, social life, and urbanization, many scholars have theorized a shift towards a third phase of capitalism, beyond mercantilism and industrialism, based in immaterial, digital, and …

Transportation Cost Index As A Performance Measure For Transportation And Land Use Systems: New Approaches And Applications, Liming Wang, Huajie Yang, Jenny H. Liu

Urban Studies and Planning Faculty Publications and Presentations

This research aims to fill gaps in existing multi-modal performance measures for transportation and land use systems:

1. As a supplement/replacement of traffic-centric measures such as LOS, travel delay;
2. Recent federal and state legislations put more emphases on using of performance measures in transportation planning & operation: MAP-21, Oregon Job and Transportation Act (OJTA);
3. Existing performance measures for transportation and land use systems, although now numerous, have their own limitation (Table 1), and leave important aspects and policy areas uncovered, for example, the balance of transportation investment between different modes and across geographical areas as mandated by OJTA

Halprin Sequence Reimagined, Andrea Villarroel, Nate Miller, Kris Decker, Foster Gough, Scott Robinson

Urban Design Workshop

The Halprin Sequence is a series of underutilized green spaces in the heart of Portland, Oregon. Once a booming attraction, as time has past and the city has grown, the Halprin Sequence has been forgotten amongst the towers. With a rich history in urban development and design, the Halprin Sequence could offer much more to the people of Portland than it is currently. The surrounding street of Fourth Avenue is also underutilized. The street is primarily used by automobiles, and the sidewalks are not pleasant to walk through.

For a green space network, the Halprin Sequence is in an ideal …

Assessing Payer Perspectives On Health Information Exchange, Dori Cross, Sunny C. Lin, Julia Adler-Milstein

OHSU-PSU School of Public Health Faculty Publications and Presentations

Objective To identify factors that impede payer engagement in a health information exchange (HIE), along with organizational and policy strategies that might effectively address the impediments.

Materials and Methods Qualitative analysis of semi-structured interviews with leaders from 17 varied payer organizations from across the country (e.g., large, national payers; state Blues plans; local Medicaid managed care plans).

Results We found a large gap between payers’ vision of what optimal HIE should be and the current approach to HIE in the United States. Notably, payers sought to be active participants in HIE efforts – both providing claims data and accessing clinical …

Curriculum and Instruction Faculty Publications and Presentations

The purpose of this research project was to highlight the practices and philosophies of two effective—but different—social studies teachers who balance the demands of teaching in the modern era while honoring their own philosophies for teaching social studies. This project was ground in the theoretical framework provided by TPACK and used a case study methodology for its research design. While the pedagogical content knowledge of the participants was strong and technology was used abundantly for instructional purposes, this research raised questions regarding how teachers can most effectively use technology to enhance instruction by helping students conceptualize content knowledge and apply …

Response Of Antarctic Cryoconite Microbial Communities To Light, Elizabeth A. Bagshaw, Jemma L. Wadham, Martyn Tranter, Rupert Perkins, Alistair Morgan, Christopher J. Williamson, Andrew G. Fountain, Sean Fitzsimons, Ashley Dubnick

Geology Faculty Publications and Presentations

Microbial communities on polar glacier surfaces are found dispersed on the ice surface, or concentrated in cryoconite holes and cryolakes, which are accumulations of debris covered by a layer of ice for some or all of the year. The ice lid limits the penetration of photosynthetically available radiation (PAR) to the sediment layer, since the ice attenuates up to 99% of incoming radiation. This suite of field and laboratory experiments demonstrates that PAR is an important control on primary production in cryoconite and cryolake ecosystems. Increased light intensity increased efficiency of primary production in controlled laboratory incubations of debris from …

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 …

Advances In Autonomous-Underwater-Vehicle Based Passive Bottom-Loss Estimation By Processing Of Marine Ambient Noise, Lanfranco Muzi

Dissertations and Theses

Accurate modeling of acoustic propagation in the ocean waveguide is important to SONAR-performance prediction, and requires, particularly in shallow water environments, characterizing the bottom reflection loss with a precision that databank-based modeling cannot achieve. Recent advances in the technology of autonomous underwater vehicles (AUV) make it possible to envision a survey system for seabed characterization composed of a short array mounted on a small AUV. The bottom power reflection coefficient (and the related reflection loss) can be estimated passively by beamforming the naturally occurring marine ambient-noise acoustic field recorded by a vertical line array of hydrophones. However, the reduced array …

Asset Mapping: Community Geography Project

The SOMA tree inventory project was taken on by a group of fourteen students as a senior capstone at Portland State University, in September of 2015. Many of us came to this class with GiS background, however, there are others representing the diverse collection of studies offered at PSU, such as film, communication, and general sciences. Capstone courses are PSU’s requirement for all seniors that allow each student to take part in helping those in the surrounding community, by providing a benefit to organizations in need of a large group of volunteers. Our capstone course was designed to impart the …

Integrating Freight Into Livable Communities, Kristine M. Williams, Alexandria Carroll

TREC Final Reports

Where livability is a goal of the planning process, freight runs the risk of not being considered except as an afterthought or as something to be excluded. Yet, freight is an integral part of local economic development. Because economic prosperity is a key characteristic of livable communities, freight must be incorporated into the planning process. This study explores the relationship between freight and livability through a comprehensive literature review and case study research. The final report includes a menu of strategies and case study perspectives that highlight the importance of transportation and land use integration, interagency coordination, and context-sensitivity in …

A Geographic View Of Expansion Choices By U.S. Firms In China, Rossitza Wooster, David Banis, Ayesha Khalid

Economics Faculty Publications and Presentations

How does geography matter for explaining the location patterns of U.S. companies in China? We combine insights from the literature on economic geography and spatial interdependence in foreign direct investment (FDI) activity, to provide a comparative analysis using both sectoral regression results and maps that illustrate patterns in the data. We use a unique sample of publicly traded U.S. firms who announced expansion of operations into China between 1980 and 2005. Regression results show that relative to the tertiary sector, firm characteristics matter more for primary sector firms, whereas province characteristics matter more for secondary sector firms. Additionally, our GIS …

Do Tods Make A Difference?, Arthur C. Nelson, Matt Miller, Dejan Eskic, Keuntae Kim, Reid Ewing, Jenny H. Liu, Matt Berggren, Zakari Mumuni

TREC Final Reports

In this report, we present research that measures the outcomes of TOD areas in relation to their metropolitan area controls with respect to (1) jobs by sector; (2) housing choice for household types based on key demographic characteristics; (3) housing affordability based on transportation costs; and (4) job-worker balance as a measure of accessibility. Prior literature has not systematically evaluated TOD outcomes in these respects with respect to light rail transit (LRT), commuter rail transit (CRT), bus rapid transit (BRT), and streetcar transit (SCT) systems. Our analysis helps close some of these gaps. We apply our analysis to 23 fixed-guideway …

Stressors And Strategies For Managing Urban Water Scarcity: Perspectives From The Field, Vivek Shandas, Rosa Lehman, Kelli L. Larson, Jeremy Bunn, Heejun Chang

Urban Studies and Planning Faculty Publications and Presentations

Largely because water resource planning in the U.S. has been separated from land-use planning, opportunities for explicitly linking planning policies to water availability remain unexamined. The pressing need for better coordination between land-use planning and water management is amplified by changes in the global climate, which will place even greater importance on managing water supplies and demands than in the past. By surveying land and water managers in two urbanizing regions of the western United States—Portland, Oregon and Phoenix Arizona—we assessed the extent to which their perspectives regarding municipal water resource management align or differ. We specifically focus on characterizing …

Delivering Green Streets: An Exploration Of Changing Perceptions And Behaviours Over Time Around Bioswales In Portland, Oregon, Glyn Everett, Jessica Lamond, Anita T. Morzillo, Annie Marissa Matsler, Faith Ka Shun Chan

Urban Studies and Planning Faculty Publications and Presentations

Green Infrastructure (GI) is an increasingly popular means of dealing with flooding and water quality issues worldwide. This study examines public perceptions of, and behaviour around, bioswales, which are a popular GI facility in the United States. Bioswales are highly visible interventions requiring support from residents and policy-makers to be implemented and maintained appropriately. To understand how the residents’ perceptions and attitudes might develop over time, we interviewed residents of Portland, Oregon, living near bioswales installed 1–2, 4–5 and 8–9 years ago, to determine awareness, understanding, and opinions about the devices. We found no consistent patterns across time periods, but …
