Public Perception Of Air Quality Risks In Portland, Oregon, Dawn Nolan

Dissertations and Theses

The availability and demand for localized air quality information from communities are on the rise. However, not all information and not all communities are the same. Effective engagement and communication strategies will depend on a community's existing knowledge, opinion about air quality, individual experiences with inequities, and more. This study aims to understand how people living in Portland, Oregon understand and experience air pollution as an environmental risk and examine the extent to which those risk perceptions relate to confidence in science and technology. This gap is critical because of the complex interaction between air pollution and the risk perception …

Virtual Community For Fat People In Outdoor Recreation, Amber C. Stephens

University Honors Theses

This paper examines online virtual communities for fat people within outdoor recreation, and how they provide connection, complex agency, and representation for fat bodies in spaces where their bodies are seen as taboo. Furthermore, it will explore the way fat bodies have been historically viewed, the lack of representation of fat bodies in the outdoors and related communities, and the gate-keeping that occurs to those who do not conform to traditional stereotypes of an outdoorsy person. Close examination of two different Instagram accounts that highlight the fat body in the outdoors will reveal three main representational elements that are an …

Returning To Rejection: Outcomes And Boundary Conditions Of Mental Illness Stereotypes, Stefanie Fox

Dissertations and Theses

Mental illness is a common condition in the United States, with over 20% of working age adults managing a mental illness condition in a given year. Disclosure of mental illness is often required for workers to take advantage of employer-provided resources (e.g., accommodations), yet use of resources is exceedingly low (less than 10%). Negative stigma-related outcomes are a top reason for which individuals delay the use of resources. Using an experimental design in an online data collection of 242 participants over two time points, the current study builds on existing organizational diversity literature to examine the stereotypes associated with mental …

Expression And Function Of Transcription Factors Foxa1, Hoxb13 And Cdx2 In Prostate Cancer, Hamsat B. Anwar

University Honors Theses

Prostate cancer (PC) is the second leading cause of death in men, affecting around 190 thousand patients in 2020 alone (National Institute of Cancer, 2020). Much of the current research focuses on treatments for advanced PC, which is problematic due to the rapid evolution of tumors and development of treatment resistance. Cancer early detection presents a better approach to control and treat patients before they acquire an incurable disease. Earlier diagnosis of patients leads to better prognosis and a more comfortable treatment process (Etzioni et al., 2003). However, we currently lack molecular markers to stratify PC during its early stages. …

Rewilding Language Education: Emergent Assemblages And Entangled Actions, Steven L. Thorne, John Hellermann, Teppo Jakonen

Applied Linguistics Faculty Publications and Presentations

Integrating concepts and techniques from ethnomethodology and sociomaterialism, this article investigates the observable material processes involving human action and place-based contexts of language use enabled by locative media. The focal pedagogical intervention utilized mobile augmented reality (AR) activities, the development of which was inspired by research on learning ‘in the wild.’ Applying the principle of reverse engineering, we introduce a pedagogical approach termed ‘rewilding’ for its emphasis on designing supportive conditions for goal-directed interaction outside of classrooms. Three instances of AR materials use are presented from an out-of-class activity associated with university-level language courses involving a quest-type AR game called …

The Soniferous Experience Of Public Space: A Soundscape Approach, Kenya Dubois Williams

Dissertations and Theses

This research explores the awareness and perceptions of practitioners regarding the role of the soundscape in understanding and managing public spaces. Without considering the role of the soundscape as part of public spaces, urban planners, designers, and policy officials cannot accurately engage in placemaking that provides a complete sensory experience. The antiquated practice of enforcing noise codes has been the traditional approach to mitigate noise (unwanted sounds). However, sound is an overlooked element in the sensory experience of cities and how individuals and communities construct a "sense of place." This study considers the implications of the soundscape approach and soundwalks …

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. …

Thermodynamics Of Ligand Binding And Global Structural Stability Of Human Serum Albumin, Matthew Walter Eskew

Dissertations and Theses

Protein structure is integral to its function. For the past 70 years differential scanning calorimetry has been used to measure protein structural stability. More recently it has been used to study macromolecular interactions. Interactions between proteins and ligands can manifest on differential scanning calorimetry melting curves or thermograms. Utilizing differential scanning calorimetry thermograms to detect or diagnose diseases has been a major goal in disease diagnostics. However, correlating specific ligand-protein interactions, as manifested in a thermogram, with a disease-specific plasma thermogram, has proven elusive.

Modified human serum albumin was utilized to develop a process to capture and retrieve ligands from …

Complex Fluid Dynamics: Chemo-Hydrodynamics Driven By Autocatalytic Reaction Fronts, Matthew Walter Eskew

Dissertations and Theses

Chemo-hydrodynamics generated from reaction-diffusion-convection processes of autocatalytic chemical systems are extensively studied for their applications in modeling complex systems. Compared to the more extensively studied autocatalytic systems, chlorite-tetrathionate and chlorite-trithionate, the chlorite-thiourea systems is relatively unexplored. Compared to the two previous systems, chlorite-thiourea has more straightforward chemical kinetics. To narrow the gap between chlorite-thiourea and the other systems a combination of experimental study and numerical simulation were employed to quantify this system.

Compared to established literature, experiments were performed at five orders of magnitude lower concentration of indicator, minimizing confounding effects of indicator on hydrodynamic motion. To accurately image the …

Gas Stations And The Wealth Divide: Analyzing Spatial Correlations Between Wealth And Fuel Branding, Jean-Carl Ende

Dissertations and Theses

The gasoline refining and sales industry has many peculiarities. One such oddity is a difference in sales, distribution and pricing between branded and unbranded gasolines. Although fuels leave the refinery a uniform commodity, branding determines entirely different marketing and pricing schemes, with entirely different volatility and risk premiums. In order to determine if this volatility is felt evenly across all wealth demographics, this study uses t-tests and CART models to analyze income, home value and other wealth-based indicators in the areas surrounding gas stations, to determine if there is a correlation between branding and wealth. The results show the wealth …
