The release of marine debris into the oceans and seas is a global issue of growing concern. These materials are harmful to marine environments and can also transport non-native species to novel habitats. Non-native species floating on marine litter is one of the lesser known impacts associated with marine debris....
The direct and indirect effects of ocean acidification (OA) are a growing concern, particularly in areas already experiencing elevated levels of oceanic CO₂. Studies with marine fishes suggest that elevated CO₂ levels may affect behavior by interfering with an important brain neurotransmitter. Studies examining the effects of OA fish behavior...
This dissertation presents the results of two studies that explored the constructs of compassion fatigue, compassion satisfaction, and self-compassion. Each study employed a cross-sectional survey design to survey elementary, middle, and high school counselors in Oregon. The online questionnaire was developed using the Professional Quality of Life Scale (Stamm, 2009),...
The near physical environment is believed to be an integral component in creating quality learning and classroom environments for young children. Free-choice play periods during preschool daily curriculums are a widespread component of preschool early childhood education. Research has demonstrated that the presence of houseplants may be a contributor to...
Studies have shown that parental feeding practice has an impact on the child's
dietary intake, food preference and weight status. Our study focused on teaching parents
the division of responsibility in parent-child feeding relationship as well as benefits of
eating meals together, since feeding practice takes place during the mealtime....
Environmental contamination along roadways with lead from processed
petroleum and automotive residues has been reported. Toxicity to the herbivores grazing these areas has not been well studied. Comparison of lead concentrations adjacent to roads in Kuwait and in Oregon, USA was studied. Soil samples were taken from three sites at...
Forest vegetation management (FVM) is an important component of reforestation in the Pacific Northwest (PNW). Several studies have demonstrated the benefits of vegetation management on planted conifer growth and survival. However, few reports have been published on the long-term effects of FVM treatments on total ecosystem biomass accumulation and aboveground...
Ph.D. candidate Qi Wei's thesis consists of two projects: Chemotherapy Project: a study based on the research paper "Predicting chemotherapy response of various cancer types using a variational auto-encoder approach" submitted to the bioRxiv preprint archive and accepted by the BMC bioinformatics; and Wound Monitor Project: implementing and assessing analytics...
Silicone wristbands are easy-to-wear passive samplers that have been readily adapted into environmental health studies since first reported in 2014. Wristbands can be worn during normal daily activities and sequester a wide range of bioavailable organic chemicals. This dissertation includes a thorough review of silicone wristband technology, as well as...
