Online Activism And Real Life Environmentalism, Emily Grace Anderson

Dissertations and Theses

Past and present human activities have created and accelerated an array of environmental catastrophes and various systems in the environment remain under threat as a result of human behavior. In hopes of mitigating environmental consequences, a social movement has arisen to encourage people to behave in ways that are more environmentally sustainable. Research shows that individual behavior choices impact the environment, and this influence can be used to positively affect the environment through engagement in pro-environmental behavior. Like with many other social movements, the internet has been a tool in spreading awareness of a cause and allowing people the opportunity …

A Ground-Based Assessment Framework For Validating Diesel Particulate Emission Models And Applicability In Portland, Or, Kirsten Marie Sarle

Dissertations and Theses

Exposure to diesel emissions causes a range of health effects throughout the body, impairing; respiratory, cardiovascular, central nervous, renal, and cognitive systems. Diesel particulate matter (DPM) in Portland, Oregon is prevalent due to the layout of highly trafficked roadways, rail lines, and marine ports exposing a dense population to high levels of exhaust pollution. These high concentrations of ambient diesel emissions disproportionately impact minority and low-income populations.

Ground-based monitoring and modeling are two ways to assess ambient DPM. However, there are uncertainties in modeled DPM due to knowledge gaps in emissions inventories as well as lack of model validation against …

Allergy And Anaphylaxis From The Prehospital Perspective, Anthony E. Conrardy

Dissertations and Theses

Anaphylaxis is considered a severe, potentially fatal, systemic allergic reaction that occurs suddenly after contact with an allergy causing substance. It is estimated that up to 5% of the population has experienced anaphylaxis, with 1% of hospitalizations and 0.1% of emergency department patients having fatal outcomes. We characterized the population of patients encountered by the EMS agency (786 patients) that had a provider impression of “allergic reaction” and then utilized logistic regression models to estimate associations with the administration of epinephrine in the prehospital setting. Additionally, we used incident location data for all patient encounters of the EMS agency …

Agency, Sense Of Place, And Knowledge On The Zumwalt Prairie: A Social Study Of Place-Based Conservation And Resilience, Dana Elyse Hellman

Dissertations and Theses

Shifting and often diminishing environmental conditions, due to climate change, resource loss, and ecosystem degradation, pose a significant concern to both social and ecological systems. The field of conservation science has attempted to address environmental threats through varying approaches, transitioning from fortress conservation and complete human exclusion to community-based and co-managed models which incorporate human actors and social dimensions in the conservation process. The latest iteration of conservation scholarship, place-based conservation, is deeply rooted in interdisciplinary, social scientific thinking, and calls for significant practitioner engagement with local knowledge, practices, social constructions, and place meanings. It is an approach which emphasizes …

An Evaluation Of Respiratory Exacerbation In New York City Given Current Trends In Climate Variability And Predictive Sociodemographic Factors, Sarah L.R. Kuril

Dissertations and Theses

Background: Within the last century, the massive increase in emissions due to economic growth has made climate variability a major problem for many of the industrialized countries and an emerging problem for the rest of the world. With an increasing number of extreme weather events, such as heat waves, cold fronts, floods, heavy rain, and storms, individuals with Chronic Obstructive Pulmonary Disease (COPD) and asthma remain a vulnerable population, placing them at highest risk of respiratory exacerbation. This dissertation aims to contribute to our understanding of how climate variability, which can influence patterns of rainfall, temperature and other variables on …

Collaboration And Evaluation In Urban Sustainability And Resilience Transformations: The Keys To A Just Transition?, Liliana Elizabeth Caughman

Dissertations and Theses

Climate has changed and will continue changing; city populations are swelling as urbanization continues to accelerate; extreme environmental events like heat waves and floods are becoming more severe and more common; and the climate justice movement is rapidly gaining momentum. It in this context that municipal governments find themselves urgently seeking solutions to transition cities from extractive, vulnerable, and unjust to sustainable, resilient, and equitable. The task is complex and will require systemic transformations across interconnected social, environmental, and economic infrastructures. Emerging theories regarding how to govern such massive changes suggest Transition Management strategies and the values of a just …

Wildlife Connectivity Modeling For The Northern Red-Legged Frog In The Portland Metropolitan Area, Oregon, Amanda Hilary Temple

Dissertations and Theses

Effective habitat connectivity tools that use GIS data perform well in remote areas but may not be as dependable in urban environments. The goal was to study uses and limitations of a conservation management tool in development, the Metro Regional Habitat Connectivity Toolkit, which evaluates connectivity for and permeability of wildlife movement. Habitat quality scores are generated from GIS-derived and field collected data such as connectivity patch/matrix characteristics, water source, vegetation, other structural components, wildlife observations, and human disturbance at survey sites. I compared GIS and field generated habitat quality scores for the Northern Red-legged Frog (Rana aurora) …

Unpacking The Process And Outcomes Of Ethical Markets: A Focus On Certified B Corporations, Renée Bogin Curtis

Dissertations and Theses

The growth in conscious consumption presents an opportunity to 1) better understand the potential outcomes of ethical market practices as a community-advocacy tool and 2) to consider potential policy considerations. The marketplace has increasingly become an arena for social action. This leads to the question of how can markets facilitate ethical business practices and community benefits? The recent rise of social benefit corporations warrants an evaluation of the outcomes of ethically-driven markets. Using a comparative research design and qualitative interview methods, this study examines certified Benefit Corporations (B Corps) in two selected cities: Philadelphia and Portland. Through interviews with B …

Emergent Women's Global Political Leadership: Progress Despite Constraints, Aoife Meehan

Dissertations and Theses

“Emergent Women’s Global Political Leadership: Progress Despite Constraints” seeks to trace why and how female political leaders emerge at the global level. Evidence points to certain cultural factors, often expressed by laws, constraining or supporting women as they seek political advancement. Data shows women leaders are emerging more and more, though slowly, as political leaders around the world. Reviewing women’s participation and representation regionally and nationally in parliaments, as ministers, and as heads of governments and states confirms that women can and do emerge as political leaders. Finally, learning about and examining women leaders themselves, their style and substance, proves …

Identifying With Remida: Early Childhood Educators’ Experiences With Reuse Materials In Reggio Emilia Inspired Identity Studies, Michelle Angela Domingues

Dissertations and Theses

Mainstream approaches to identity studies in early childhood education (ECE) are problematic from both social constructivist and early childhood education for sustainability perspectives. Mainstream approaches are influenced by behaviorist theories of developmental psychology literature which privilege individual identity, whereas emerging discourses in identity theory trend toward discussing the multiplicity of social identities. Alternatively, and in contrast to traditional behaviorist and cognitive learning theories, cultural centers like Reggio Emilia, Italy’s Remida Creative Recycling Center promote reuse material projects that socially construct identities in Reggio’s Municipal Infant/Toddler Centers and Preprimary Schools by giving value to waste materials through offering such materials in …

Tree Canopy Cover And Potential In Portland, Or: A Spatial Analysis Of The Urban Forest And Capacity For Growth, Jeff Ramsey

Dissertations and Theses

Urban forests have positive impacts on human and ecosystem health, reduce stress on aging stormwater infrastructure, increase property values, and reduce energy consumption. The scale of these benefits ranges from the hyper-local to the global. While the benefits of urban forests can extend well beyond the boundaries of cities, they often do not reach all residents of the city equally. Urban forest policies do not adequately address environmental equity or employ planting strategies with knowledge of the social and political factors that determine the spatial variations of tree canopy extent in cities. Chapter I analyzes the determinants of current canopy …

Recognizing And Addressing Risk Ambiguity In Sea Level Rise Adaptation Planning: A Case Study Of Miami-Dade County, Florida, Mary Ann Rozance

Dissertations and Theses

As coastal cities around the world identify and implement adaptations to sea level rise, they are faced with competing interests around what should be done and how to prioritize actions. Often, environmental problems--like confronting the challenge of sea level rise--are posed as requiring expert driven, technical solutions to identify and mitigate risks across the landscape. This framing, however, ignores the way in which diverse knowledge can help inform long-term planning horizons that address complex ways that sea level rise affects communities. The failure to integrate diverse knowledge into sea level rise adaptation can result in barriers to implementation and outcomes …

Mold, Allergic Diseases And Asthma: Assessing The Validity And Usefulness Of Indoor Air Sampling As A Tool In Providing Health Protective Advice To Occupants, William M. Sothern

Dissertations and Theses

Background: Asthma is a major health problem throughout the world, disproportionately affecting occupants of low-income housing, and exposure to damp and moldy living conditions is recognized as a significant risk factor for asthma and other respiratory diseases. However, there are no authoritative health guidance values (HGV's) for airborne mold, and current scientific thought holds that the establishment of such guidelines is not practicable. Nonetheless, environmental practitioners take air samples for mold as a routine component of their indoor environmental investigations and use the laboratory results as a tool together with other findings to guide recommendations for health protective actions. The …

Environmental Justice In Natural Disaster Mitigation Policy And Planning: A Case Study Of Flood Risk Management In Johnson Creek, Portland, Oregon, Seong Yun Cho

Dissertations and Theses

This study aims to explore the possibility of environmental justice as social consensus and an institutional framework to reduce socioeconomic differences in natural disaster vulnerability through a case study of flood risk management in Johnson Creek, Portland, Oregon. First, by analyzing institutions, policies, and currently ongoing flood mitigation projects, this study investigates how federal and local governments are addressing and responding to current flood problems. Second, through flood expert surveys and GIS spatial analysis, this study examines various factors that contribute to communities' susceptibility to flood risks, and whether there exist spatial differences between physically and socioeconomically vulnerable communities within …

White Space, Black Space: Community Gardens In Portland, Oregon, David Ross Billings Jr.

Dissertations and Theses

Community gardens have been the focus of social science research in the United States for several decades and the benefits associated with these alternative food spaces has been well documented. More recently, scholars have begun to argue that these benefits are inequitably distributed across society. Largely as a result of the whiteness of these spaces, people of color are less represented in community and benefit less from their presence. Portland, Oregon is recognized as a leader in sustainability, with its abundance of community gardens and urban agriculture. It is also one of the whitest urban cities in the United States. …

An Analysis Of The Bizx Commercial Trade Exchange: The Attitudes And Motivations Behind Its Use, Ján André Montoya

Dissertations and Theses

The Global Financial Crisis underscored both the complexity and brittleness of the global financial system, especially for small to medium enterprises dependent on the current banking regime for credit. More than ever, we have also begun to see the disentanglement of small businesses from traditional banks at the local and regional level in the form of CDFIs, fintech alternative lending, and now complementary currencies. Through interviews with the management and members of the BizX complementary currency this study asks what the attitudes and motivations are behind its offering and use. In addition, it inquires into the economic and psychological benefits …

The Dispute Over The Commons: Seed And Food Sovereignty As Decommodification In Chiapas, Mexico, Carol Frances HernáNdez RodríGuez

Dissertations and Theses

Seeds have become one of the most contested resources in our society. Control over seeds has intensified under neoliberalism, and today four large multinational corporations control approximately 70 percent of the global seed market. In response to this concentration of corporate power, an international social movement has emerged around the concept of seed sovereignty, which reclaims seeds and biodiversity as commons and public goods. This study examines the relationship between the global dynamics of commodification and enclosure of seeds, and the seed sovereignty countermovement for decommodification. I approach this analysis through an ethnographic case study of one local seed sovereignty …

Is Therapy Going To The Dogs? Evaluating Animal Assisted Therapy For Early Identified At-Risk Children, Leah Faith Brookner

Dissertations and Theses

This study explores the historical context of human-animal relationships and examines the important ways that humans benefit from various types of interactions with domesticated animals. Therapeutic approaches that incorporate animals have been shown to have multiple benefits, including improved physical and mental health. Although this area of study is still largely overlooked in scientific fields of study, including social work, Animal Assisted Therapy (AAT) has become increasingly prevalent in various mental health settings. Despite its popularity and anecdotal support, research on the benefits of AAT with children is minimal; there are no studies examining the ways in which this approach …

Reducing Arsenic Exposure From Private Well Water In The United States: The Use, Effect, And Potential Of Testing Requirements, Sara Flanagan

Dissertations and Theses

Over 45 million Americans drink from unregulated private well water of unknown quality. Arsenic is the most concerning groundwater contaminant for health because of its toxicity and widespread natural occurrence. Most residential wells in arsenic-affected areas have not been tested for arsenic; the success of community programs and efforts to motivate testing is limited by a range of psychological, situational, and socioeconomic barriers. However, testing only acts as screening and does not reduce exposure without effective and consistent actions to follow. Given the limitations in relying on individual well owners to be aware, willing, and capable of testing their water, …

Responsible Pet Ownership: Dog Parks And Demographic Change In Portland, Oregon, Matthew Harris

Dissertations and Theses

Dog parks are the fastest growing type of park in U.S. cities; however, their increasing popularity has been met with increasing criticism of pets in public space. Dogs have shown to be a deep source of neighborhood conflict, and the provision of dog parks, or off-leash areas, is a seemingly intractable controversy for city officials. In 2003, Portland, Oregon established a network of 33 off-leash areas which remains the second largest both in count and per capita in the country. The purpose of my research is to understand the public debate over off leash dogs during the establishment of Portland's …

Grassroots Resistance In The Sustainable City: Portland Harbor Superfund Site Contamination, Cleanup, And Collective Action, Erin Katherine Goodling

Dissertations and Theses

How does progressive change happen in so-called sustainable cities? In this dissertation, I present findings from a three year-long ethnographic investigation of grassroots organizing in Portland, Oregon, a city at the leading edge of the green urbanism movement. This research centered on an extended case study of the Portland Harbor Community Coalition (PHCC). PHCC is an alliance of grassroots groups working to ensure that cleanup of the Portland Harbor Superfund Site benefits those who have been most impacted by pollution. In this dissertation, I develop three main empirical findings. First, despite depoliticized (sustainability) discourse permeating the harbor cleanup planning process, …

From Food To Food Justice: Pathways And Narratives Of Young Food Activists In New York City, Amy Kwan

Dissertations and Theses

With a rise in obesity and other non-communicable, diet-related health problems and the persistence of food insecurity among many vulnerable populations, the involvement of young people in the current, burgeoning food-justice movement has the potential to bring forth transformative changes to our food system and thus improve population health. While much is known about the outcomes of providing opportunities for young people to be actively and civically engaged in their communities, there is a lack of research on the pathways, narratives, and experiences that bring young people into food justice activism.

Through semi-structured, in-depth interviews with 25 young food activists …

Food Access Narratives In Southeast Portland, Oregon, Gwyneth Genevieve Mckee Manser

Dissertations and Theses

Since the late 1990's, "food deserts" have dominated the academic and policy literature on food access and food security. Food deserts are defined as areas that lack easy access to fresh, healthy, and affordable food, and are typically measured using Geographic Information Systems and spatial data sets. However, while food deserts may provide a useful measure for identifying food insecurity at a broad scale, they fail to account for individual definitions and perceptions of food access (Barnes et al. 2015; McEntee 2009). Furthermore, the food desert model assumes a lack of agency on the part of low-income populations (Alkon et …

Explaining Unequal Transportation Outcomes In A Gentrifying City: The Example Of Portland, Oregon, Eugenio Arriaga Cordero

Dissertations and Theses

This dissertation examines unequal outcomes of urban transportation policies in the neoliberal era. It focuses on inequalities in the Portland, Oregon metro area between 1994 and 2011 as measured in three key areas: 1) access to public transit; 2) the journey-to-work; and 3) "household-serving" trips. Growing concern over the harmful impacts from an increasing dependence on cars has led planners in the U.S. to encourage a modal shift from private car to public transit, bicycling, and walking. The required policies to make this modal shift possible, however, might inadvertently be benefiting "choice" riders at the cost of transport disadvantaged groups. …

Local Approaches To Regional Problems: Suburban Government Responses To Portland's Regional Housing Crisis, Emma Deppa

Dissertations and Theses

The Portland metropolitan region has seen unprecedented growth in the last three decades, resulting in both economic expansion and considerable gentrification. While lauded for its commitment to sustainability and a "smart development" ethos, many questions remain for the city with respect to the needs of displaced residents and a burgeoning population of young professionals. This study examines how various levels of government implement growth management policies to accommodate these demographic changes, and aims to assess whether and how the consequences of growth, especially gentrification and displacement, are meaningfully addressed. Qualitative interviews were conducted with staff members and elected officials from …

Building Social Sustainability From The Ground Up: The Contested Social Dimension Of Sustainability In Neighborhood-Scale Urban Regeneration In Portland, Copenhagen, And Nagoya, Jacklyn Nicole Kohon

Dissertations and Theses

In response to growing social inequality, environmental crises, and economic instability, sustainability discourse has become the dominant "master signifier" for many fields, particularly the field of urban planning. However, in practice many sustainability methods overemphasize technological and economic growth-oriented solutions while underemphasizing the social dimension. The social dimension of sustainability remains a "concept in chaos" drawing little agreement on definitions, domains, and indicators for addressing the social challenges of urban life. In contrast, while the field of public health, with its emphasis on social justice principles, has made significant strides in framing and developing interventions to target the social determinants …

Socio-Spatial Transformation And Contested Space At The Street Level In Latin America: The Case Of Cali, Colombia, Maria Janeth Mosquera Becerra

Dissertations and Theses

Since 2008, more than 50% of the world's population has lived in cities and it is projected that by 2050 around 87% will do so. Designing infrastructure in urban spaces has become increasingly critical for achieving human well-being. This dissertation examines socio-spatial transformation processes related to urbanization, economic development and the marginalization of utilitarian cycling in Cali, Colombia, as a particular expression of the struggle for transportation space occurring in urban areas. The research analyzes (a) the socio-spatial processes that have restricted the use of bicycles as a means of transportation in the city of Cali, Colombia; and (b) the …

Cultivating Common Ground? A Case Study Of A Community Garden Organization In Northeast Portland, Oregon, Bryan James Zinschlag

Dissertations and Theses

When it comes to the topic of environmental sustainability, most of us will readily agree that we face a litany of local and global environmental threats in the twenty-first century. As such, we would largely agree that the need to address climate change and other issues is urgent. Where this agreement tends to end, however, is on the question of whether this urgency is so great that we need not address issues of inequality and environmental justice when organizing sustainability efforts. Some are convinced that, because sustainability efforts are "saving the world for everyone", so to speak, issues of environmental …

Participation, Information, Values, And Community Interests Within Health Impact Assessments, Nicole Iroz-Elardo

Dissertations and Theses

Health impact assessment (HIA) has emerged in the U.S. as one promising process to increase social and environmental justice through addressing health equity issues within planning. HIA practice is guided by values such as democracy and equity and grounded in broad social determinants of health. The most readily applied definition of democracy is problematic because it implies an element of direct, participatory engagement with the public. This is at odds with HIA practice that largely relies on stakeholder engagement strategies.

This dissertation critically examines the engagement strategies of three transportation planning HIA cases to more fully understand how the HIA …
