Pedestrian Pedagogy Of Place: Nurturing An Ecological Consciousness Through Slow Explorations Of The Public Realm, Kevin M. Pozzi Oct 2018

Pedestrian Pedagogy Of Place: Nurturing An Ecological Consciousness Through Slow Explorations Of The Public Realm, Kevin M. Pozzi

Leadership for Sustainability Education Comprehensive Papers

As increasing institutional paralysis and polarization demonstrate, citizens are not engaged or motivated by ecological challenges because they struggle to identify with our catastrophic relationship to nature in this urban, anthropocentric, and climactically-fraught modern era. Rather than focus solely on natural areas as a pathway to ecological consciousness and action, educators can inspire citizens through a “Pedestrian Pedagogy of Place” that brings wonder and enchantment into our urban public realm. Using the principles of sustainability education and place-based education as a framework, this pedagogy recognizes the sidewalk and pedestrian experience as a shared classroom through sensory, awareness-based learning modalities.


Stacking Functions: Identifying Motivational Frames Guiding Urban Agriculture Organizations And Businesses In The United States And Canada, Nathan Mcclintock, Michael Simpson Apr 2017

Stacking Functions: Identifying Motivational Frames Guiding Urban Agriculture Organizations And Businesses In The United States And Canada, Nathan Mcclintock, Michael Simpson

Urban Studies and Planning Faculty Publications and Presentations

While a growing body of scholarship identifies urban agriculture's broad suite of benefits and drivers, it remains unclear how motivations to engage in urban agriculture (UA) interrelate or how they differ across cities and types of organizations. In this paper, we draw on survey responses collected from more than 250 UA organizations and businesses from 84 cities across the United States and Canada. Synthesizing the results of our quantitative analysis of responses (including principal components analysis), qualitative analysis of textual data excerpted from open-ended responses, and a review of existing literature, we describe six motivational frames that appear to ...

The article looks into the critical geographic information science (GIS) in approaching questions both emerging and enduring around the intersection of the spatial and the digital. It offers trading zones for discussion of issues, for building alliances and interrogating tensions, and for a constant dialectical process of critique and renewal. One tension running through critical GIS is the contradictory role it has played in addressing questions of social justice.


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 Dec 2015

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 ...


A Critical Physical Geography Of Urban Soil Contamination, Nathan Mcclintock Jul 2015

A Critical Physical Geography Of Urban Soil Contamination, Nathan Mcclintock

Urban Studies and Planning Faculty Publications and Presentations

Anthropogenic lead (Pb) is widespread in urban soils given its widespread deposition over the course of the 19th and 20th centuries via a range of point- and non-point sources, including industrial waste and pollution, leaded paint, and automobile exhaust. While soil scientists and urban ecologists have documented soil Pb contamination in cities around the world, such analyses rarely move beyond proximal mechanisms to focus on more distal factors, notably the social processes mediating Pb accumulation in particular places. In this paper, I articulate a critical physical geography of urban soil Pb contamination that considers the dialectical coproduction of soil and ...


Overcoming Uncertainty And Barriers To Adoption Of Blue-Green Infrastructure For Urban Flood Risk Management, Colin R. Thorne, E. C. Lawson, Connie P. Ozawa, Samantha Hamlin, Leonard A. Smith Jan 2015

Overcoming Uncertainty And Barriers To Adoption Of Blue-Green Infrastructure For Urban Flood Risk Management, Colin R. Thorne, E. C. Lawson, Connie P. Ozawa, Samantha Hamlin, Leonard A. Smith

Urban Studies and Planning Faculty Publications and Presentations

Blue-Green Infrastructure (BGI) and Sustainable Drainage Systems (SuDS) are increasingly recognised as vital components of urban flood risk management. However, uncertainty regarding their hydrologic performance and lack of confidence concerning their public acceptability create concerns and challenges that limit their widespread adoption. This paper investigates barriers to implementation of BGI in Portland, Oregon, using the Relevant Dominant Uncertainty (RDU) approach. Two types of RDU are identified: scientific RDUs related to physical processes that affect infrastructure performance and service provision, and socio-political RDUs that reflect a lack of confidence in socio-political structures and public preferences for BGI. We find that socio-political ...


Development Of Future Land Cover Change Scenarios In The Metropolitan Fringe, Oregon, U.S., With Stakeholder Involvement, Heejun Chang, Roberrt W. Hoyer Mar 2014

Development Of Future Land Cover Change Scenarios In The Metropolitan Fringe, Oregon, U.S., With Stakeholder Involvement, Heejun Chang, Roberrt W. Hoyer

Geography Faculty Publications and Presentations

We describe a future land cover scenario construction process developed under consultation with a group of stakeholders from our study area. We developed a simple geographic information system (GIS) method to modify a land cover dataset and then used qualitative data extracted from the stakeholder storyline to modify it. These identified variables related to our study area’s land use regulation system as the major driver in the placement of new urban growth on the landscape; and the accommodation of new population as the determinant of its growth rate. The outcome was a series of three scenario maps depicting a ...


Public Policy And Sexual Geography In Portland, Oregon, 1970-2010, Elizabeth Morehead Jan 2012

Public Policy And Sexual Geography In Portland, Oregon, 1970-2010, Elizabeth Morehead

Dissertations and Theses

Drawing on the concept of sexual geography, this study examines the social and political meanings of sexualized spaces in the urban geography of Portland, Oregon between 1970 and 2010. This includes an examination of the sexual geography of urban spaces as a deliberate construct resulting from official and unofficial public policy and urban planning decisions. Sexual geographies, the collective and individual constructions of sexuality, are not static. Nor are definitions of deviant sexual practices fixed in the collective consciousness. Both are continuously being reshaped and reconstructed in response to changing economic structures and beliefs about sex, race and class. Primary ...


Streamflow Analysis And A Comparison Of Hydrologic Metrics In Urban Streams, Matthew Lawton Wood Jan 2012

Streamflow Analysis And A Comparison Of Hydrologic Metrics In Urban Streams, Matthew Lawton Wood

Dissertations and Theses

This study investigates the hydrologic effects of urbanization in two Portland, Oregon streams through a comparison of three hydrologic metrics. Hydrologic metrics used in this study are the mean annual runoff ratio (Qa), mean seasonal runoff ratio (Qw and Qd), and the fraction of time that streamflow exceeds the mean streamflow during the year (TQmean). Additionally, the relative change in streamflow in response to storm events was examined for two watersheds. For this investigation urban development is represented by two urbanization metrics: percent impervious and road density. Descriptive and inferential statistics were used to evaluate the relationship between the hydrologic ...

Future Flooding Impacts On Transportation Infrastructure And Traffic Patterns Resulting From Climate Change, Heejun Chang, Martin Lafrenz, Il-Won Jung, Miguel A. Figliozzi, Rolando Melgoza, David Ruelas, Deena Platman, Cindy Pederson

Geography Faculty Publications and Presentations

This study investigated potential impacts of climate change on travel disruption resulting from road closures in two urban watersheds in the Portland metropolitan area. We used ensemble climate change scenarios, a hydrologic model, stream channel survey, a hydraulic model, and a travel forecast model to develop an integrated impact assessment method. High-resolution climate change scenarios are based on the combinations of two emission scenarios and eight general circulation models. The Precipitation-Runoff Modeling System was calibrated and validated for the period 1988-2006, and simulated for determining the probability of floods from 2020-2049. We surveyed stream cross sections at five road crossings ...

Impacts Of Climate Change And Urban Development On Water Resources In The Tualatin River Basin, Sarah Praskievicz May 2009

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 ...


Building And Maintaining A Statewide Transportation Framework, Kenneth Dueker, Paul Bender Nov 2002

Building And Maintaining A Statewide Transportation Framework, Kenneth Dueker, Paul Bender

Center for Urban Studies Publications and Reports

Creating and maintaining up-to-date sharable Geographic Information SystemsTransportation (GIS-T) data is challenging. Many states are working on Transportation Framework efforts to build a complete, consistent, and current transportation data layer in conjunction with the NSDI and Geospatial One-Stop efforts. This paper summarizes an effort that systematically re-examined transportation data sharing issues as part of the development of a Transportation Framework for the State of Washington. Business needs were assessed in terms of spatial and temporal accuracy needs of stakeholders and users of a state-wide Transportation Framework. A conceptual model was developed for a Transportation Framework with emphasis on data flows ...

Patterns Of Time, Place, And Culture: Land Use Zoning In Portland, Oregon, 1918-1924, Meg Merrick Jan 1998

Patterns Of Time, Place, And Culture: Land Use Zoning In Portland, Oregon, 1918-1924, Meg Merrick

Dissertations and Theses

Until recently, few have questioned the notion that the separation of uses in land use zoning is inherently correct. Many observers of the city are now suggesting that zoning, as it has been practiced in this country over the last 80 years, has created cities that are fractured and function poorly. Others propose that zoning should be reconsidered as a remedy for urban dysfunction. They suggest that the whole notion of zoning be rethought.

The purpose of this study is to uncover some of the underlying rationales and methodologies that set the model for zoning. This study examines the rationales ...


Hawthorne Boulevard: Commercial Gentrification And The Creation Of An Image, Rachel Ann Hardyman Jan 1992

Hawthorne Boulevard: Commercial Gentrification And The Creation Of An Image, Rachel Ann Hardyman

Dissertations and Theses

Portland's Southeast Hawthorne Boulevard illustrates commercial gentrification in progress. Once a declining service district, "Hawthorne" is now one of the city's most popular shopping streets. Tracing and classifying businesses, using address listings from city directories, gives an accurate picture of changes since 1980. Three parallel trends can be distinguished in the makeup of the business mix: a shift from services to retailing; a move towards a regional, rather than a neighborhood, market area; and a cultural upgrading associated with the influx of increasingly expensive stores. Classification also aids in the definition of a tipping point at which revitalization ...

GIS research has evolved by trial and error. We need to think more systematically about GIS research. New technology and societal needs are important determinants of issues that govern GIS research strategies. URISA has a stake in fostering GIS research, particularly research that is appliications driven.


Modeling Location For Cadastral Maps Using An Object-Oriented Computer Language, Daniel Kjerne Jan 1986

Modeling Location For Cadastral Maps Using An Object-Oriented Computer Language, Daniel Kjerne

Center for Urban Studies Publications and Reports

The challenge to designers of multipurpose computer-aided land information systems is to capture enough of the "deep structure" of the problem domain to enable a system to answer user questions and requests in a satisfactory way. Criteria defining "satisfactory" in each case must include considerations of accuracy, completeness, timeliness, and cost. These considerations, when applied to the location in space of parcel boundaries and property corners, present unusual difficulties. This is in large measure due to the fact that important elements of the field measurement process, and the determination of location based on what are essentially logical {legal) abstractions, are ...


Report On Feasibility Of A Geographic Information System For The Central City Citizen Planning Committees, Kenneth Dueker, George Mason Jun 1985

Report On Feasibility Of A Geographic Information System For The Central City Citizen Planning Committees, Kenneth Dueker, George Mason

Center for Urban Studies Publications and Reports

In September 1984 PSU was contracted to demonstrate the utility of an interactive graphic database system. A project was done using LANDTRAK* to determine which records from the tax roll were inside the Central City Planning Area. This information provides a starting point for o parcel based information system for the Central City Planning Project. This report consists of a design for a geographic information system for the Central City Planning Area that may serve as a prototype for a broader geographic information system for the City.


Public Transit And Student Choice : A Survey With Portland State University Students, Sheku Gibril Kamara Jan 1980

Public Transit And Student Choice : A Survey With Portland State University Students, Sheku Gibril Kamara

Dissertations and Theses

Research in urban transportation has been of many facets. Some have emphasized modes and routes while others have attempted to isolate and look at small segments of the transportation market with specific demands. Such segments include workers, recreation riders, and to a less extent, students. In the "journey-to-work" studies, a major finding has been that as income of workers increases, the distance between residence and work-place also increases.

This thesis starts with a series of hypotheses generated as a result of the findings of other studies reviewed in the literature. In testing the hypotheses, variables that are likely to influence ...


Spatial Variations In The Intra-Urban Response To A Noise Source, Wilbur David Conder May 1973

Spatial Variations In The Intra-Urban Response To A Noise Source, Wilbur David Conder

Dissertations and Theses

Most research on the urban sonic environment has been recent. One finding has been that physical noise exposure indices calibrate poorly with human noise response. The vagaries of human response to noise have given impetus to research to isolate the factors that differentiate human response to noise. The present thesis continues this research.

The thesis specifies human noise response to occur on three levels: awareness, annoyance, and complaint. The factors that structure each level of noise response are identified in the published Iiterature.

Noise awareness is a function of noise exposure. Noise annoyance is a function of noise exposure to ...
