This study aims to improve knowledge of how suspended particulate matter (SPM) affects hydrophobic contaminant transport in the lower Columbia River and its estuary, using polycyclic aromatic hydrocarbons (PAHs) as model compounds. It is hypothesized that PAHs are transported to the estuarine turbidity maximum (ETM), a prime feeding zone in...
Analysis of suspended particulate material (SPM) collected from the Columbia River and its estuary in 2007–2008 revealed the ubiquitous presence of polycyclic aromatic hydrocarbons (PAHs) from several distinct sources. The two dominant ones were: (1) a suite of non-alkylated, three to five-ringed compounds derived from high temperature combustion and (2)...

Parasites are ubiquitous members of ecological communities, capable of contributing to the decline of vulnerable populations. Therefore, monitoring parasite level is a critical component for host management. Molecular tools, such as quantitative polymerase chain reaction (qPCR), can be valuable additions to monitoring protocols that assess parasitic disease risk to hosts....
Legislation can be an effective public health tool, and understanding the factors that influence legislative outcomes is advantageous for public health practitioners who propose and advocate for legislation. The literature indicates that the issues of personal freedoms, the presence or absence of strong coalition leadership, and political conditions and ideology...
Given the vital role of forest ecosystems in landscape pattern and process, it is important to quantify the effects, feedbacks, and uncertainties associated with forest disturbance dynamics. In western North America, insects and wildfires are both native disturbances that have influenced forests for millennia, and both are projected to increase...
This thesis explores the administrative issues that factor into the teaching of writing online. I explore these issues by situating the Conference on College Composition and Communication Position Statement of Principles and Example Effective Best Practices for Online Writing Instruction at the center of this project by both examining and...
The purpose of this thesis is to argue that LeBron James’ expressions of activism are, in many ways, perceived as insincere, hypocritical or disingenuous to his followers on the social media platform Twitter. Using the theoretical framework of Affect Theory and Plutchik’s wheel of emotions, a close reading was conducted...
