The purpose of this dissertation is to investigate Oregon public high school history teacher perspectives concerning standards-based reform initiatives springing from the No Child Left Behind legislation. The central question addressed in this study is: At what level has Standards-Based Education reform initiatives impacted Oregon high school history instruction and...
The use of Native American fire regimes evolved in the Klamath-Siskiyou bioregion over millennia. A mixture of Native American and Euro-American socio-cultural management has developed from adaptations to climate, topography, ecological processes, and land use practices. This research incorporates Traditional Ecological Knowledge (TEK) to partially examine the role of tribal...
Due to a growing body of literature documenting declines in pollinator populations, there has been increased public interest in pollinator conservation. In urban and suburban landscapes, many gardeners and urban land managers are interested in gardening for pollinators, particularly bees. Simultaneously, many homeowners and municipalities are interested in other aspects...
The purpose of this study was to examine the evidence of construct validity for self-report with assistance from a secondary source as a measure of physical activity (PA) in adults with intellectual disabilities (ID) in free-living environments. Thirty-seven participants (21 females, 16 males) with mild to moderate ID aged 19-74...
While human tool-use proficiency helped define our history, the cognitive and perceptual mechanics of how humans use tools are not fully understood. This question is of great value to the design of hand-held tools and prosthetics. A prominent theory, tool embodiment, suggests that tool use is facilitated by a flexible...
China has experienced rapid economic growth in the last twenty years, accompanied by large-scale land conversion, severe environmental degradation, and rising carbon dioxide (CO₂) emissions. Designing policies for sustainable development requires a comprehensive understanding of the relationship between economic growth, land-use change, carbon sequestration and emissions in China. This dissertation...
Changes in ocean conditions influenced by climatic fluctuations have lead to changes in individual species distributions, which alter the diversity, communities and species interactions across marine ecosystems worldwide. Assessing the species composition and identifying regions and habitats that can safeguard the persistence of biota are critically important. In this dissertation,...
Western hemlock-Sitka spruce forests, where prior precommercial thinning has occurred, constitute one of the most productive
young-growth management types along the Pacific Coast from Oregon to southeast Alaska. These stands are ready for a first commercial thinning entry, however, the costs and benefits of such entries and resulting impacts at...
Software entropy impacts the overall quality of software systems. High entropy hinders developers from understanding the purpose of a piece of code and can cause developers to make sub-optimal changes and introduce bugs. Researchers have used entropy scores to measure the naturalness of code. However, thus far, no one has...
