Mapping The Publics: The Production Of Spatial Knowledge And Public Interest, Paul Thomas Manson

Dissertations and Theses

Over the past decades, calls for comprehensively managing and planning ocean resources have emerged internationally and within the United States. Central to these calls is a drive to expand coastal and marine spatial planning with a particular focus on technologically mediated public involvement. These new public involvement technologies aim, more quickly and thoroughly, to solicit and analyze public values and existing uses of the coastal and marine environments. One particular technological innovation is the use of participatory geographic information systems (PGIS). These new tools allow for stakeholders, members of the public, and planning entities to collect, visualize, and interact with …

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 Collaborative Approach To Cultural Resource Risk Assessment, Preservation, And Prioritization: A Case Study From Sauvie Island, Oregon, Phillip James Daily

Dissertations and Theses

New and increasing threats to cultural heritage resources have pushed archaeologists, land managers, and Indigenous peoples to develop strategies to identify at-risk resources, determine condition, vulnerabilities, and value of said resources, and then provide mitigation and preservation prioritizations and recommendations for the future. One such strategy is the risk assessment approach. Typically, to guide ongoing and future management of vulnerable cultural resources, risk assessments consider preexisting archaeological data, alongside geomorphological and hydrological landform characteristics, to prioritize sites for preservation. While such assessments have been conducted around the globe, they have not been widely applied on the Lower Columbia of Oregon …

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 …

Exposure Characterization And Assessment Of Airborne Chemicals And Sars-Cov-2 Transmission In New York City Nail Salons, Amelia P. H. Watkins

Dissertations and Theses

Background: Currently, there are 156,000 people employed as manicurists or pedicurists in the United States. Employment in this sector is expected to grow by 10% over the next decade. Exposure assessments have revealed that salon workers are chronically exposed to a variety of substances that cause respiratory sensitization, developmental problems, contact dermatitis, blood, liver, and kidney issues, as well as nervous system impacts. Most recently, the SARS-Cov-2 pandemic has raised the issue of the vulnerability of nail salon workers to airborne infectious diseases as well. This dissertation aims to characterize and assess the chemical exposures that nail salon workers …

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 …

Urban Lakes: Ecosystem Services And Management, Laura Costadone

Dissertations and Theses

Lakes provide a variety of ecosystem services and benefits that greatly contribute to urban sustainability. Despite the growing interest in integrating freshwater systems into management and policy decisions, urban lakes are often overlooked in land-use planning. Nutrient and pollutant runoff from the surrounding urbanized watershed result in water quality deterioration that negatively impact the lake ecological functions and related ecosystem services. The vulnerability and degradation of these urban ecosystems should be a matter of concern, especially considering that, in rapidly growing metropolitan areas, the demand for aesthetic and recreational services provided by urban lakes is increasing. The overall goal of …

Biological Invasions In Coastal Marine Ecosystems: How Changes In Trade Are Linked To Ballast Water Delivery Of Nonindigenous Species, Danielle Elizabeth Verna

Dissertations and Theses

Globalization has escalated transfers of nonindigenous species (NIS) across natural dispersal barriers. The resulting biological invasions have become a leading global mechanism of ecological change. NIS are often transported between coastal marine ecosystems in the ballast water of commercial ships, and patterns of NIS introduction and establishment can be linked to global trade dynamics. Here I examined drivers of trade and ballast water across spatial and temporal extents of invasion. The analyses incorporated a variety of datasets on trade, industries, and ship behavior to identify fluctuations in globally transported commodities that lead to changes in maritime shipping patterns and frequency. …
