Improving Trip Generation Methods For Livable Communities, Kelly J. Clifton, Nico Larco, Kristina Marie Currans, Jael Wettach-Glosser

TREC Final Reports

Recent efforts to improve trip generation data available for transportation impact analysis of new development include the collection of multimodal trip generation data, development of models that account for the built environment, and new recommendations for practice. Building on a long line of research on transportation and built environment, many studies have identified important features of the surrounding built environment that most impact trip rates and mode shares, building on a long line of research on transportation and the built environment. Despite these improvements in data and methods, less attention is placed on identifying the conditions of the site itself …

Cultivating (A) Sustainability Capital: Urban Agriculture, Eco-Gentrification, And The Uneven Valorization Of Social Reproduction, Nathan Mcclintock

Urban Studies and Planning Faculty Publications and Presentations

Urban agriculture (UA), for many activists and scholars, plays a prominent role in food justice struggles in cities throughout the Global North, a site of conflict between use and exchange values, and rallying point for progressive claims to the right to the city. Recent critiques, however, warn of its contribution to gentrification and displacement. The use/exchange value binary no longer as useful an analytic as it once was, geographers need to better understand UA’s contradictory relations to capital, particularly in the neoliberal Sustainable City. To this end, I bring together feminist theorizations of social reproduction, Bourdieu’s “species of capital”, and …

Effects Of Spatially Distributed Stream Power On Check Dam Function In Small Upland Watersheds: A Case Study Of The Upper Laja Watershed, Guanajuato, Mexico, Zachary Andrew Herzfeld

Dissertations and Theses

Watershed restoration comes in a variety of forms depending on which set of problems are sought to be remedied. Severe soil erosion, in the form of gullying and/or headcutting, can be mitigated through constructing check dams in well-selected locations. This practice has been used throughout the upland subwatersheds within the Upper Laja River watershed in Guanajuato, México. The present study employed Wolman pebble counts to systematically assess the effectiveness of 21 check dams located near the city of San Miguel de Allende. Particle size distributions taken directly downstream and upstream of each check dam were differentiated, aggregated and compared--with the …

Out In "The Numbers": Youth And Gang Violence Initiatives And Uneven Development In Portland's Periphery, Dirk Kinsey

Dissertations and Theses

Incidence of youth and gang violence in the Portland, Oregon metro area has increased dramatically over the past five years. This violence has recently become more spatially diffuse, shifting outwards from gentrified, inner city neighborhoods, towards the city's periphery. These incidents exist within the context of a shifting regional political economy, characterized by a process of gentrification associated displacement and growing, and distinctly racialized and spatialized, inequalities. While gang researchers have long argued a corollary between the emergence of gangs and economically and culturally polarized urban landscapes, the ongoing suburbanization of poverty in American cities suggests a new landscape of …

The Contribution Of Sense Of Place To Social-Ecological Systems Research: A Review And Research Agenda, Vanessa A. Masterson, Richard C. Stedman, Johan Enqvist, Maria Tengö, Matteo Giusti, Darin Wahl, Uno Svedin

Urban Studies and Planning Faculty Publications and Presentations

To develop and apply goals for future sustainability, we must consider what people care about and what motivates them to engage in solving sustainability issues. Sense of place theory and methods provide a rich source of insights that, like the socialecological systems perspective, assume an interconnected social and biophysical reality. However, these fields of research are only recently beginning to converge, and we see great potential for further engagement. Here, we present an approach and conceptual tools for how the sense of place perspective can contribute to social-ecological systems research. A brief review focuses on two areas where relation to …

Cultural Identity And Cuisine In Taiwan, Cassidy A. Pfau

University Honors Theses

This paper explores the relationship between food, culture, and national identity in the Taiwanese context. Beginning with a review of relevant Taiwanese history, this paper then shifts into a theoretical discussion on the topics of hybridity, globalization, identity formation, and how cuisine impacts cultural and national identity. In order to understand how these theories operate in Taiwan, a discussion of three topics is then presented: Aboriginal culture and cuisine, Japanese colonial history and its impact on Taiwanese identity, and Taiwanese-specialty foods as a symbol of national identity. Taiwan has created a unique cultural heritage using cuisine (among other cultural elements), …

Do People’S Perceptions Of Neighborhood Bikeability Match “Reality”?, Liang Ma, Jennifer Dill

Urban Studies and Planning Faculty Publications and Presentations

Do people perceive the built environment the same as we objectively measure it? If not, what are the relative roles of the objective versus the perceived environment on bicycling behavior? This study, based on data from Portland, Oregon, explored the match or mismatch between the objective and perceived bicycling environment and how it affects people’s bicycling behavior. The descriptive analysis indicated a fair agreement between perceived and objective measures. Older adults, women having children, less-educated and lower-income persons, and those who bicycle less tended to perceive their high-bikeable environment (measured objectively) as being a low-bikeable environment. In addition to the …

Urban Non-Timber Forest Products Stewardship Practices Among Foragers In Seattle, Washington (Usa), Rebecca J. Mclain, Melissa R. Poe, Lauren S. Urgenson, Dale Blahna, Lita P. Buttolph

Geography Faculty Publications and Presentations

Our research seeks to expand the concept of urban environmental stewardship to include the everyday stewardship practices of urban nontimber forest products foragers. Ethnographic data from 58 urban foragers and 18 land stewards in the city of Seattle (USA) revealed that foragers reported using a variety of practices to enhance and minimize negative desirable species and their habitats. Many of these practices were identical to those practiced by restoration volunteers in formal programs and align with Seattle Parks Department management objectives. Foragers actively sought to learn more about what practices are sustainable; many mentored others in sustainable harvesting practices. Most …

Evaluating Hourly Rainfall Characteristics Over The U.S. Great Plains In Dynamically Downscaled Climate Model Simulations Using Nasa-Unified Wrf, Huikyo Lee, Duane E. Waliser, Robert Ferraro, Takamichi Iguchi, Christa D. Peters-Lidard, Baijun Tian, Paul C. Loikith, Daniel B. Wright

Geography Faculty Publications and Presentations

Accurate simulation of extreme precipitation events remains a challenge in climate models. This study utilizes hourly precipitation data from ground stations and satellite instruments to evaluate rainfall characteristics simulated by the NASA-Unified Weather Research and Forecasting (NU-WRF) regional climate model at horizontal resolutions of 4, 12, and 24 km over the Great Plains of the United States. We also examined the sensitivity of the simulated precipitation to different spectral nudging approaches and the cumulus parameterizations. The rainfall characteristics in the observations and simulations were defined as an hourly diurnal cycle of precipitation and a joint probability distribution function (JPDF) between …

City Of Gresham Stormwater Retrofit Master Plan, Teresa F. Huntsinger

Civil and Environmental Engineering Master's Project Reports

The Stormwater Retrofit Master Plan identifies more than 50 stormwater retrofit project opportunities across three watersheds in the City of Gresham. The retrofit projects are prioritized in a scoring system to evaluate the costs and benefits of diverse project sizes and types. Project types range from bioswales and planters in city parking lots and along arterial roads, to regional end-of-pipe facilities and retrofits of existing detention ponds. Top projects will move forward for further assessment, design and construction, helping the city achieve its water quality improvement goals. The scoring system may be used to evaluate additional projects in the future.

Mapping The Nonstationary Internal Tide With Satellite Altimetry, Edward Zaron

Civil and Environmental Engineering Faculty Publications and Presentations

t Temporal variability of the internal tide has been inferred from the 23 year long combined records of the TOPEX/Poseidon, Jason-1, and Jason-2 satellite altimeters by combining harmonic analysis with an analysis of along-track wavenumber spectra of sea-surface height (SSH). Conventional harmonic analysis is first applied to estimate and remove the stationary components of the tide at each point along the reference ground tracks. The wavenumber spectrum of the residual SSH is then computed, and the variance in a neighborhood around the wavenumber of the mode-1 baroclinic M2 tide is interpreted as the sum of noise, broadband nontidal processes, and …

Election 2016: Voter Turnout And Results Across Oregon, Kevin Curry

Metroscape

Metroscape went inside the numbers from the 2016 general election. We examined Oregon’s new "motor voter" law to see if it affected turnout and to better understand the new voters added to the rolls in the ‘Beaver State.’ We looked at voter turnout and election results in Clackamas, Columbia, Multnomah, Washington, and Yamhill counties in Oregon and Clark and Skamania counties in Washington to answer several questions about the 2016 General Election.

Periodic Atlas Of The Metroscape: The Geography Of Future Housing, Randy Morris, Sheila Martin

Metroscape

In this edition of the Periodic Atlas, we provide a glimpse of housing construction that has been permitted over the past few years, with a focus on multifamily housing. Focusing on recently-permitted units provides a perspective on how the newest housing is and will be different from existing housing. The type of housing that will be built, where it is built, its characteristics, and its price will shape the Portland region in the years to come.

Innovator Or Butcher?: Herophilean Research Methods In Early Ptolemaic Alexandria, Annastasia C. Conner

University Honors Theses

In a period of Ptolemaic Alexandria that has been referred to by modern scholars as a "frontier environment" for scientific achievement and discoveries, Herophilus of Chalcedon was a leader of innovation. Religious and cultural boundaries and the presence of taboos and death-based pollution should perhaps have limited his research capabilities, but under the patronage of the ruling Ptolemaic kings (Ptolemy I Soter, and Ptolemy II Philadelphus both reigned during Herophilus' lifetime), he and his contemporaries were able to dissect and vivisect human cadavers within the pursuit of their studies. Although Herophilus' therapeutic practices largely fell within the scope of the …

Lacking Legitimacy: Neoliberal Governance And The Erosion Of Local Democracy In The United States And Argentina, Adriane Ackerman

University Honors Theses

An extension of capitalism’s relentless growth, neoliberal globalization has characterized most of the policies and practices that have proliferated between nation-states since the late 1970's, producing a "flatter" world in which spheres of influence, both economically and politically, have become inextricably interdependent. Some prominent results of this interdependence include consolidation of wealth, extreme socioeconomic stratification, greater influence of money upon politics, and deepening ideological divide within the populace. Increased sharing of the roles and responsibilities of governing with the private sector, along with increased access to information and exposure to systemic nepotism, have together undermined the sovereignty and preeminence of …

Shifting Wetland Policy And Perception In The Columbia Slough, Ryan Pemberton

Geography Masters Research Papers

On the periphery of Portland, Oregon, at the confluence of the Willamette and Columbia rivers lies an expansive wetland, the Columbia Slough. Once a thriving wetland ecosystem nineteen miles long by three miles wide, the Slough has been drained, filled, and developed into a humanized landscape. The human experience of this landscape has always been about use: people make, move, and exchange things here. Few people actually live and play in this transformed wetland, and most would consider it a featureless, polluted, and otherwise valueless landscape save for the money to be made here. Yet remnants of the old, wild …

Towards An Intellectual History Of Evolutionary Economics: Competition And Struggle Versus Cooperation And Mutual Aid, John B. Hall, Svetlana Kirdina-Chandler

Economics Faculty Publications and Presentations

Our inquiry considers the origins of Evolutionary Economics by reintroducing a debate that took place in Russia in the 19th and early 20th century. Responses to Charles Darwin’s The origin of Species are considered, especially critiques stressing Darwin’s emphasis upon competition and struggle in natural selection, that can be traced directly to Thomas Robert Malthus. Considering challenging contributions made by several Russian scholars, we place special emphasis upon Peter Kropotkin’s focus on cooperation and “mutual aid” in natural selection and evolution. We then speculate upon the commonality found in the evolutionary views advanced by Kropotkin and his American contemporary, Thorstein …

Assessing State Efforts To Integrate Transportation, Land Use And Climate, Rebecca Lewis, Robert Zako

TREC Final Reports

Climate change is increasingly recognized as a threat to life on earth. “Continued emission of greenhouse gases will cause further warming and long-lasting changes in all components of the climate system, increasing the likelihood of severe, pervasive and irreversible impacts for people and ecosystems. Limiting climate change would require substantial and sustained reductions in greenhouse gas emissions” (International Panel on Climate Change, 2014, 8).

The transportation sector accounts for almost one-third of all greenhouse gas emissions (GHG) in the United States. Reducing GHG from transportation rests on the “three-legged stool” of improving vehicle efficiency, reducing the carbon content of fuels …

St. Johns Housing Action Plan, Jai Singh, Julia Michel, Andres Oswill, Gabriel Rousseau, Ludwig Salzmann, Eric Rutledge

Master of Urban and Regional Planning Workshop Projects

The St. Johns Housing Action Plan (Action Plan) is designed to serve vulnerable St. Johns residents who are first to feel the impacts of increased housing costs and market pressures. It also intends to capture the support of residents who are not at risk of displacement but realize that the neighborhood change they fear is partly fueled by housing instability.

Challenging Queer As “Neoliberal”: The Radical Politics Of South Asian Diasporic Lesbian Representational Culture, Sri Craven

Women, Gender, and Sexuality Studies Faculty Publications and Presentations

This essay contributes to transnational feminist and queer interests in neoliberalism, sexual politics and representational cultures that all circulate globally today. It reads Deepa Mehta’s film, Fire (1996), and Suniti Namjoshi’s literary venture, Goja: An Autobiographical Myth (2000). Each processes the question of lesbian visibility as a question of female labor and class relations among women. By analyzing representations of lesbian life in the context of laboring female bodies, the article challenges the dismissal of queer politics as neoliberal in India. Sexual identity politics, as critics argue, often dovetails with neoliberalism’s project of protecting elite and bourgeois subjects’ interests at …

A Diachronic Approach To The Old Spanish Sibilant Merger And Its Impact On Trans-Atlantic Spanish. Part Ii., Eva NúÑEz-MéNdez

World Languages and Literatures Faculty Publications and Presentations

This article is a continuation of Part I, published in the previous volume of Estudios Hispanicos.

The evolution of the medieval sibilant phonetic system is crucial to understanding the origin of Castilian varieties on both sides of the Atlantic. It helps to distinguish varieties such as Andalusian Spanish, Judeo- Spanish, and trans-Atlantic Spanish, which constitute proof of many of the diachronic processes happening during and after the late medieval period. This study helps the reader understand the linguistic variations of the sibilants in the modem language, and explores the origins and different steps in their evolution; furthermore, it evaluates recent …

The Effects Of Frequency Of Social Interaction, Social Cohesion, Age, And The Built Environment On Walking, Gretchen Allison Luhr

Dissertations and Theses

The purpose of this dissertation was to explore, through a social ecological framework, the multifaceted effects of the neighborhood environment by investigating how dimensions of both the built environment and the neighborhood social context may interact to influence walking. Aesthetics, land use mix, crime, and pedestrian infrastructure were considered with respect to built environment walkability, and the neighborhood social context was conceptualized using measures of both social cohesion and social interaction with neighbors. This research used data from an Environmental Protection Agency (EPA)-funded study of 748 adults (18 years of age and older) residing in the Lents neighborhood in Portland, …

Peak Pedaling: Has Portland Bicycling Reached The Top Of The Logistic Curve?, Robert Mccullough

PSU Transportation Seminars

The recent City Club report on bicycling provided an opportunity to collect and analyze a number of data sets including the new Hawthorne Bridge data. One question is where Portland bicycling on the logistic curve -- a common tool for judging the maturity of a developing product or activity. Logistic curves are used for marketing, for epidemiology, and even for visits to Indian owned casinos. The preliminary evidence is that we are reaching the horizontal area of the curve. Additional evidence Our further research into future policies indicates a shift to bicycle boulevards in order to attract more risk averse …

Citizen-Led Urban Agriculture And The Politics Of Spatial Reappropriation In Montreal, Quebec, Claire Emmanuelle Bach

Dissertations and Theses

Urban Agriculture (UA) has been practiced in Montreal, Quebec for well over a century. In the last five years or so, a renewed enthusiasm for UA has manifested itself in the form of citizen-led UA projects. The latter are often established in residual spaces, from vacant lots to sidewalks, and alleyways. These more spontaneous and informal UA practices point to a shift in how urban inhabitants perceive and use urban space. Through a case study of informal UA projects in Montreal, QC, this work brings attention to the dynamics surrounding the establishment of citizen-led UA projects, paying special attention to …

Unmanned Aerial Vehicle Based Structure From Motion Biomass Inventory Estimates, Emily Jane Bedell

Dissertations and Theses

Riparian vegetation restoration efforts demand cost effective, accurate, and replicable impact assessments. In this thesis a method is presented using an Unmanned Aerial Vehicle (UAV) equipped with a GoPro digital camera to collect photogrammetric data of a 2.02-acre riparian restoration. A three-dimensional point cloud was created from the photos using Structure from Motion (SfM) techniques. The point cloud was analyzed and compared to traditional, ground-based monitoring techniques. Ground truth data collected using the status-quo approach was collected on 6.3% of the study site and averaged across the entire site to report stem heights in stems/acre in three height classes, 0-3 …

A Marine Reservoir Effect ∆R Value For Kitandach, In Prince Rupert Harbour, British Columbia, Canada, Kevan Edinborough, Andrew Martindale, Gordon T. Cook, Kisha Supernant, Kenneth M. Ames

Anthropology Faculty Publications and Presentations

Prince Rupert Harbour (PRH), on the north Pacific Coast of British Columbia, contains at least 157 shell middens, of which 66 are known villages, in an area of approximately 180 km2. These sites span the last 9500 yr and in some cases are immense, exceeding 20,000 m2 surface area and several meters in depth. Recent archaeological research in PRH has become increasingly reliant on radiocarbon dates from marine shell for developing chronologies. However, this is problematic as the local marine reservoir effect (MRE) remains poorly understood in the region. To account for the MRE and to better date the Harbour’s …

Surviving Catastrophe: Resource Allocation And Plant Interactions Among The Mosses Of Mount St. Helens Volcano, Trevor David Williams

Dissertations and Theses

Mosses are some of the first colonizers to disturbed sites, yet their roles in early plant community structuring are not well understood. The primary succession zones of volcanoes provide opportunities to conduct natural experiments into how mosses contribute to early plant community formation, as well as how the unique environments found in such zones affect plant traits, particularly those associated with stress tolerance. Though plant community changes have been well-documented since Mount St. Helens (MSH) volcano erupted in 1980, the volcano's moss assemblages, their influence on other plants, and their potential roles in chemical-mediated competition and biogeochemical cycling have garnered …
