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)...
Confluence is a newsletter of Oregon Sea Grant. Articles feature the supported research and events of the program.
This issue of Confluence includes articles on: potential of farming gooseneck barnacles, educating boaters on proper waste disposal, Dungeness crab genetics study, how to reduce injuries for crabbers at sea, women's changing...
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...
The Columbia River Gillnetter is the pilot of the Lower Columbia River commercial fishing industry, keeping fishermen and the public in touch with today's important issues.
The localized impact of blooms of the mixotrophic ciliate Myrionecta rubra in the Columbia River estuary during 2007-2010 was evaluated with biogeochemical, light microscopy, physiological, and molecular data. M. rubra affected surrounding estuarine nutrient cycles, as indicated by high and low concentrations of organic nutrients and inorganic nitrogen, respectively, associated...
The purpose of this research was to determine if there were any relationships between measured personality traits and vocational interests between the Adult Learner with Learning Disabilities (ALLD) and without Learning Disabilities (ALNLD). Instruments utilized to measure personality traits and vocational interests included the Myers Briggs Type Indicator (MBTI) and...
Includes 1922 Summer School Graduates.
In the following pages the information, so far as it has been possible to obtain it, is given in the following order for each alumnus: Name, year in which the degree was conferred, degree, course, present occupation, and present mailing address.
Chinese international students in American colleges and universities report low levels of physical activity involvement, which may limit them in terms of
realizing their full human potential (i.e., cognitively, physically, socially). The purpose of this dissertation was to investigate the psychosocial mechanisms as well as the sociocultural influences to understand...
Environmental DNA (eDNA) is an emerging biological monitoring tool that can aid in assessing the effects of forestry and forest manufacturing activities on biota. Monitoring taxa across broad spatial and temporal scales is necessary to ensure forest management and forest manufacturing activities meet their environmental goals of maintaining biodiversity. Our...
The U.S Pacific Northwest contains a wide variety of ecosystems, all subject to relatively dry summers and wet winters. As has been shown with paleoclimatic and paleoecological data, the region is vulnerable to changes in climate. We assessed the sensitivities of vegetation distributions, carbon stocks, and fire regimes to 21st...
Oregon's estuaries are important ecosystems for scientific study. Consequently, knowledge of what research has been conducted helps us identify benchmarks and plan new projects. A comprehensive bibliography of published research, technical reports, local documents, and data sets is one means of recording this knowledge. For these reasons, the Guin Library...
On May 21, 1998 Kip Kinkel drove to Thurston High School in Springfield, Oregon. Kinkel killed two students and wounded another twenty-two students. He killed his parents the day before. The shootings at Thurston High School came on the heels of a number of prominent school shootings and Kip Kinkel...
