Data Colonialism Through Accumulation By Dispossession: New Metaphors For Daily Data, Jim Thatcher, David O'Sullivan, Dillon Mahmoudi Dec 2015

Data Colonialism Through Accumulation By Dispossession: New Metaphors For Daily Data, Jim Thatcher, David O'Sullivan, Dillon Mahmoudi

Urban Studies and Planning Faculty Publications and Presentations

In recent years, much has been written on ‘big data’ in both the popular and academic press. After the hubristic declaration of the “end of theory” more nuanced arguments have emerged, suggesting that increasingly pervasive data collection and quantification may have significant implications for the social sciences, even if the social, scientific, political and economic agendas behind big data are less new than they are often portrayed. Compared to the boosterish tone of much of its press, academic critiques of big data have been relatively muted, often focusing on the continued importance of more traditional forms of domain knowledge and …


Utilizing Humidity And Temperature Data To Advance Monitoring And Prediction Of Meteorological Drought, Ali Behrangi, Paul C. Loikith, Eric J. Fetzer, Hai M. Nguyen, Stephanie L. Granger Nov 2015

Utilizing Humidity And Temperature Data To Advance Monitoring And Prediction Of Meteorological Drought, Ali Behrangi, Paul C. Loikith, Eric J. Fetzer, Hai M. Nguyen, Stephanie L. Granger

Geography Faculty Publications and Presentations

The fraction of land area over the Continental United States experiencing extreme hot and dry conditions has been increasing over the past several decades, consistent with expectation from anthropogenic climate change. A clear concurrent change in precipitation, however, has not been confirmed. Vapor pressure deficit (VPD), combining temperature and humidity, is utilized here as an indicator of the background atmospheric conditions associated with meteorological drought. Furthermore, atmospheric conditions associated with warm season drought events are assessed by partitioning associated VPD anomalies into the temperature and humidity components. This approach suggests that the concurrence of anomalously high temperature and low humidity …


Beyond Fruit: Examining Community In A Community Orchard, Emily Jane Becker Nov 2015

Beyond Fruit: Examining Community In A Community Orchard, Emily Jane Becker

Dissertations and Theses

The Fruits of Diversity Community Orchard, located in Portland, Oregon in an affordable housing neighborhood, is a site of alternative food provisioning in which a group of people, organized by two nonprofits, work together to manage fruit and nut producing plants. Through conversations with volunteers who participate regularly and participant observation, this study explores the questions: What does community mean in the context of a community orchard? In what ways does partnering with a nonprofit from outside the neighborhood influence community and the way the project is operationalized?

This thesis situates community orchards within the literature on alternative food networks …

The Neoliberal Politics Of “Smart”: Electricity Consumption, Household Monitoring, And The Enterprise Form, Anthony M. Levenda, Dillon Mahmoudi, Gerald Sussman Nov 2015

The Neoliberal Politics Of “Smart”: Electricity Consumption, Household Monitoring, And The Enterprise Form, Anthony M. Levenda, Dillon Mahmoudi, Gerald Sussman

Urban Studies and Planning Faculty Publications and Presentations

This article investigates how digital technologies in the energy sector are enabling increased value extraction in the cycle of capital accumulation through surveillant proceesses of everyday energy consumption. We offer critical theory (Gramsci, Foucault) and critical political economy (Marx) as a guide for critical understanding of value creation in ICT through quotidian processes and practices of social reproduction. In this regard, the concept of the "prosumer" is extended beyond notions of voluntary participation in Web 2.0 to the political economy of energy use. Within this broad framework we investigate national and local level "smart grid" campaigns and projects. The "smartening" …


Examining The Right To Bicycle: Synergies And Tensions Between Human Rights, Civil Rights, And Planning For Cycling, Aaron Golub Oct 2015

Examining The Right To Bicycle: Synergies And Tensions Between Human Rights, Civil Rights, And Planning For Cycling, Aaron Golub

PSU Transportation Seminars

Securing and expanding the broad right to bicycle, including the right to adequate and safe street space and related infrastructure for cycling along with other policies and protections for cyclists, is the obvious goal of cycling advocacy efforts in their various forms. All rights are situated within frameworks for promulgating and insuring they are honored, and the right to cycling is no different. This project investigates how the right to bicycle falls within various rights frameworks, focusing on broad human rights and civil rights frameworks while reflecting as well on traffic safety codes and transportation planning frameworks. While certain aspects …


Webinar: Transport Cost Index: A New Comprehensive Performance Measure For Transportation And Land Use, Liming Wang Oct 2015

Webinar: Transport Cost Index: A New Comprehensive Performance Measure For Transportation And Land Use, Liming Wang

TREC Webinar Series

Recent federal and state policies are placing increasing emphasis on using comprehensive transportation performance measures to guide transportation decision making processes covering policy areas ranging from mobility, safety, economy and livability, to issues of equity and environment. While it is relatively easy to build consensus on mobility measures that center on the transportation system alone, it is much harder for performance measures to incorporate both transportation and land use, loosely defined as accessibility measures, even with continuous efforts to catalog and design such measures.

Two projects at PSU sponsored by Oregon DOT and National Institute of Transportation Communities (NITC) aim …

Short-Tailed Temperature Distributions Over North America And Implications For Future Changes In Extremes, Paul C. Loikith, J. David Neelin Oct 2015

Short-Tailed Temperature Distributions Over North America And Implications For Future Changes In Extremes, Paul C. Loikith, J. David Neelin

Geography Faculty Publications and Presentations

Some regions of North America exhibit nonnormal temperature distributions. Shorter-than-Gaussian warm tails are a special subset of these cases, with potentially meaningful implications for future changes in extreme warm temperatures under anthropogenic global warming. Locations exhibiting shorter-than-Gaussian warm tails would experience a greater increase in extreme warm temperature exceedances than a location with a Gaussian or long warm-side tail under a simple uniform warm shift in the distribution. Here we identify regions exhibiting such behavior over North America and demonstrate the effect of a simple warm shift on changes in extreme warm temperature exceedances. Some locations exceed the 95th percentile …


Modeling Vegetation Mosaics In Sub-Alpine Tasmania Under Various Fire Regimes, Gabriel I. Yospin, Samuel W. Wood, Andrés Holz, David M.J.S. Bowman, Robert E. Keane, Cathy Whitlock Oct 2015

Modeling Vegetation Mosaics In Sub-Alpine Tasmania Under Various Fire Regimes, Gabriel I. Yospin, Samuel W. Wood, Andrés Holz, David M.J.S. Bowman, Robert E. Keane, Cathy Whitlock

Geography Faculty Publications and Presentations

Western Tasmania, Australia contains some of the highest levels of biological endemism of any temperate region in the world, including vegetation types that are conservation priorities: fire-sensitive rainforest dominated by endemic conifer species in the genus Athrotaxis; and fire-tolerant buttongrass moorlands. Current management focuses on fire suppression, but increasingly there are calls for the use of prescribed fire in flammable vegetation types to manage these ecosystems. The long-term effects of climate and alternative management strategies on the vegetated landscape are unknown. To help identify controls over successional trajectories, we parameterized a spatially explicit landscape-scale model of vegetation and fire …

The Language Ecology Of Sierra Leone, George Tucker Childs Oct 2015

The Language Ecology Of Sierra Leone, George Tucker Childs

Applied Linguistics Faculty Publications and Presentations

Many of Sierra Leone’s indigenous languages are robust and enjoy some support on the national level. Mende and Temne, for example, receive government support in terms of materials having been created for developing literacy in those languages. Other Sierra Leone languages receive support in nearby countries, e.g., Mandingo (Malinké) and Kisi in Guinea. Three languages in Sierra Leone, however, receive no such support and will likely disappear in a generation, namely, the three South Atlantic languages Mani (Bullom So), Kim (Krim) and Bom (Bum). A fourth language belonging to the same group, Sherbro, the subject of an upcoming investigation, has …


Transportation Leadership Education: Portland Traffic And Transportation Course A Case Study And Curriculum, Nathan Mcneil Oct 2015

Transportation Leadership Education: Portland Traffic And Transportation Course A Case Study And Curriculum, Nathan Mcneil

Urban Studies and Planning Faculty Publications and Presentations

The Portland Traffic and Transportation course serves a number of different purposes. On one hand, it is designed to develop citizens who are informed about the transportation system, including how it got where it is today, what agencies and actors play a role in its operation and development, and how they, as citizens, play a role in its future. In this sense, there is a goal of broadening and deepening the existing knowledge about the system among the general population. On the other hand, there is an implicit goal of encouraging participation in the system with the understanding that doing …


Language Policy And Bilingual Education For Immigrant Students At Public Schools In Japan, Naomi Asakura Sep 2015

Language Policy And Bilingual Education For Immigrant Students At Public Schools In Japan, Naomi Asakura

Dissertations and Theses

This thesis discusses the current Japanese language (nihongo) education for immigrant students at public schools in Japan and provides recommendations through the study of language policy and the comparison of bilingual education in the United States. The current situation of a decreasing birth rate and increasing aging population in Japan has led to the acceptance of more foreign workers. Due to this change, language education in Japan has increasing development. The focus of chapter 1 is on the theories of language policy. This paper particularly focuses on the ideas of Wright (2004), Neustupný (2006), Spolsky (2004), and Cooper (1989), and …


A Town On Fire: The Copperfield Affair Of 1914, Daniel Joseph Shepard Sep 2015

A Town On Fire: The Copperfield Affair Of 1914, Daniel Joseph Shepard

Dissertations and Theses

In 1914, Copperfield, Oregon was militarily occupied by order of the governor, Oswald West. Its town government was deposed, the city officials were arrested, and the town's saloons were closed and all liquor and gambling devices were seized. The town, previous to Governor West's interdiction, had seen a breakdown into violence and arson between two competing saloon cliques. The resulting martial law of Copperfield and subsequent court battles between the governor and Copperfield's saloonkeepers would become known as the Copperfield Affair.

The purpose of this study is to explain how and why the Copperfield Affair happened. The event which precipitated …


Inspiring Action: Measuring The Effect Of Motivational Frames On Social Movement Mobilization, Rebecca Louise Smith Sep 2015

Inspiring Action: Measuring The Effect Of Motivational Frames On Social Movement Mobilization, Rebecca Louise Smith

Dissertations and Theses

In order to probe how social movement messages foster participant mobilization, this study utilized an experimental design to investigate collective action frames, core messaging tasks that define problems, assign blame, convey a plan of action, and inspire participation. The study compared the effects of climate change messages that contain motivational frames with those that do not, incorporating the influence of resonance, and exposure to competing and counter frames. Results revealed that motivational frames contributed to mobilization, especially intention to act, under conditions of resonance and with exposure to counter frames. Salience primed participants to respond to motivational frames, however for …

Development Of A Pedestrian Demand Estimation Tool, Kelly Clifton, Patrick Allen Singleton, Christopher D. Muhs, Robert J. Schneider Sep 2015

Development Of A Pedestrian Demand Estimation Tool, Kelly Clifton, Patrick Allen Singleton, Christopher D. Muhs, Robert J. Schneider

Civil and Environmental Engineering Faculty Publications and Presentations

Most research on walking behavior has focused on mode choice or walk-trip frequency. In contrast, this study is one of the first to analyze the destination choice behaviors of pedestrians. Using about 4,500 walk trips from a 2011 household travel survey in the Portland, OR, region, we estimated multinomial logit pedestrian destination choice models for six trip purposes. Independent variables included terms for impedance (walk-trip distance); size (employment by type, households); supportive pedestrian environments (parks, a pedestrian index of the environment variable called PIE); barriers to walking (terrain, industrial-type employment); and traveler characteristics. Unique to this study was the use …


A Geospatial Tool For Wetland Prioritization At The Watershed Scale, Debra Sue Blackmore, Heejun Chang Sep 2015

A Geospatial Tool For Wetland Prioritization At The Watershed Scale, Debra Sue Blackmore, Heejun Chang

Institute for Natural Resources Publications

There is an increasing demand for assessing ecosystem functions for freshwater wetlands, especially when comparing or prioritizing among wetlands at the watershed scale. We estimated the relative potential of selected ecosystem functions for freshwater wetlands within a watershed using widely available geospatial data. We developed four functions to estimate 1) flood storage, 2) late season flow, 3) sediment retention and 4) temperature control in four pilot watersheds in Oregon (Tualatin, Coquille, Upper Grande Ronde and Sprague). These watersheds are geographically separated from each other representing diverse ecoregion environments. Spatial analysis and geographic information system (GIS) were designed for maximum re-use, …


Crowdsourcing The Collection Of Transportation Behavior Data, Christopher Bone, Seth Kenbeek, Ken Kato, Jacob Bartruff Sep 2015

Crowdsourcing The Collection Of Transportation Behavior Data, Christopher Bone, Seth Kenbeek, Ken Kato, Jacob Bartruff

TREC Final Reports

Understanding the travel behaviors of individuals who use public transit is essential for enhancing the performance, sustainability and efficiency of public transportation. Contemporary methods for collecting data on transportation behavior are focused on manual or automated procedures for counting the number of individual passengers entering or exiting transit vehicles. While such methods provide useful data for understanding transit demand throughout a network, they ignore the important details of how passengers travel to and within a network as well as their personal experiences during their commute, all of which can enrich the ability of transit agencies to provide sustainable transportation. To …

Promising Practices For Long-Term Community Engagement, Meg Merrick, Andrée Tremoulet, Tina Dippert Aug 2015

Promising Practices For Long-Term Community Engagement, Meg Merrick, Andrée Tremoulet, Tina Dippert

Institute of Metropolitan Studies Publications

Washington County has initiated a planning process to rethink the structure and support system for its ongoing, long-term community participation program. The impetus for this planning process began with a fall 2014 announcement by the service provider that had supported the county’s Citizen Participation Organizations (CPOs) and the Committee for Citizen Involvement (CCI) for several decades, Oregon State University Extension, that it would no longer continue this role effective fall 2015. The planning process has since evolved into an opportunity to take a thorough look at the program and plan a system of engagement for the 21st century.

Washington County …


Evaluating The Use Of Crowdsourcing As A Data Collection Method For Bicycle Performance Measures And Identification Of Facility Improvement Needs, Miguel A. Figliozzi, Bryan Philip Blanc Aug 2015

Evaluating The Use Of Crowdsourcing As A Data Collection Method For Bicycle Performance Measures And Identification Of Facility Improvement Needs, Miguel A. Figliozzi, Bryan Philip Blanc

Civil and Environmental Engineering Faculty Publications and Presentations

This research developed a smartphone application called ORcycle to collect cyclists’ routes, users, and comfort levels. ORcycle combines GPS revealed route data collection with new questionnaires that try to elicit cyclists’ attitudes as well as comfort levels and factors that influence their perceived comfort and route choice. The new questionnaires were developed to better understand how cyclists’ comfort levels are affected by route characteristics, route stressors, safety reports, cyclists’ demographics, and cyclists’ cycling attitude. Preliminary results show that many trip characteristics, route choice factors, route stressors and demographic variables are correlated with comfort levels. ORcycle is the first statewide deployment …

A Critical Race Analysis Of Travel For Transformation: Pedagogy For The Privileged Or Vehicle For Socio-Cultural Transformation?, James Arthur Gambrell Jul 2015

A Critical Race Analysis Of Travel For Transformation: Pedagogy For The Privileged Or Vehicle For Socio-Cultural Transformation?, James Arthur Gambrell

Dissertations and Theses

Transformative learning theory (TLT) describes the process of reframing discriminative, untenable worldviews with a more inclusive, permeable, and reflective epistemology. Although TLT has been around for more than 50 years, few studies empirically engage critical theoretical frameworks to move beyond personal learning to identify the impacts of transformation on society. Through a critical race theory (CRT) framework, this study analyzed how the participants' socio-cultural identities (race, class, gender, sexuality, and heritage language) impacted the transformative learning of eight study-abroad students from a medium-sized, rural Midwestern university. Focusing on the extent to which the participants experienced the elements of transformative …


Naturally Occurring Background Levels Of Arsenic In The Soils Of Southwestern Oregon, Heather Ann Hurtado Jul 2015

Naturally Occurring Background Levels Of Arsenic In The Soils Of Southwestern Oregon, Heather Ann Hurtado

Dissertations and Theses

This study examines the natural background concentrations of arsenic in the soils of southwest Oregon, using new samples in addition to data collected from previous theses (Khandoker, 1997 and Douglas, 1999). The original 213 samples were run by ICP-AES with a reporting limit of 20 ppm, and only three samples had detected values. The original samples were tested again (2013) at a lower reporting limit of 0.2 ppm by ICP-MS, as were 42 new samples (2013), to better ascertain the natural levels of arsenic in undisturbed soils. The aim is to add to the existing DEQ data set, which has …


Evaluating User Interaction With A Web-Based Group Decision Support System: A Comparison Between Two Clustering Methods, Martin Swobodzinski, Piotr Jankowski Jul 2015

Evaluating User Interaction With A Web-Based Group Decision Support System: A Comparison Between Two Clustering Methods, Martin Swobodzinski, Piotr Jankowski

Geography Faculty Publications and Presentations

Task-Technology Fit theory and the Technology Acceptance Model identify system utilization as an important indicator for the performance of complex software systems. Yet, empirical evaluations of user interaction with group decision support systems are scarce and often methodologically underdeveloped. For this study we employed an exploratory evaluation of user interaction in the context of web-based group decision support systems. Specifically, we used information-rich server logs captured through a web-based platform for participatory transportation planning to identify groups of users with similar use patterns. The groups were derived through multiple sequence alignment and hierarchical cluster analysis based on varying user activity …


Toward A Spatial-Temporal Measure Of Land-Use Mix, Steven R. Gehrke, Kelly Clifton Jul 2015

Toward A Spatial-Temporal Measure Of Land-Use Mix, Steven R. Gehrke, Kelly Clifton

Civil and Environmental Engineering Faculty Publications and Presentations

Urban planning and public-health research has long been interested in the connection between land-use mix and travel. Interest from urban planners stems from the potential of transportation efficiency gains achieved by an increased land-use mix and subsequent shortening of trip lengths; whereas, public-health research advocates an increased land-use mix as an effective policy for facilitating greater physical activity. Yet, despite the transportation, land-use, and health benefits related to improving land-use mix and the extent of topical attention given by researchers, no consensus has been reached regarding the magnitude of its effect on travel. This absence of agreement may largely be …

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 …
