In order to understand better the defect structure and dynamics associated
with lower valent dopants complexed with native defects in group IV oxides, In/Cd
perturbed angular correlation spectroscopy was performed in ceria and zirconia. Examining
the orientation symmetry axis of defects in ceria single crystals at low temperature
has allowed...
We develop several a-priori and a-posteriori error estimates for two-grid finite element discretization of coupled elliptic and parabolic systems with a set of parameters P. We present numerical results that verify the convergence order of the numerical schemes predicted by the a-priori estimates. We present numerical results that verify the...
Riparian forests provide a myriad of ecosystem functions for adjacent streams and rivers, and due to these linkages, changes in riparian forest conditions can have direct implications for stream ecosystems. Resource managers in the coast redwood forests (Sequoia sempervirens) of northern California (USA) are actively thinning second-growth stands to accelerate...
The current thesis presents contingent valuation research incorporating social psychological measures that investigates recreationists' willingness to pay recreation access fees at McDonald-Dunn Forest, Oregon. Context is provided through an extensive literature review of recreation fee management, issues and concerns related to recreation fees, recreationists' attitudes toward fees, relevant social psychological...
We review and synthesize the geologic record that
constrains the sources of sea level rise and freshwater discharge
to the global oceans associated with retreat of ice
sheets during the last deglaciation. The Last Glacial Maximum
(~26–19 ka) was terminated by a rapid 5–10 m sea
level rise at 19.0–19.5...
Generalization is a fundamental mathematical practice across all disciplines and content areas (Amit & Klass, 2005; Lannin, 2005; Pierce, 1902; Vygotsky, 1986; Ellis, Lockwood, Tillema & Moore, 2017). While a considerable amount of research has been conducted on students' generalizing activity in algebraic contexts (Amit & Klass 2005; Becker &...
The Forest Service and the Bureau of Land Management propose to adopt coordinated ecosystem management direction for the lands they administer within the range of the northern spotted owl. This Supplemental Environmental Impact Statement (SETS) presents as alternatives the options, with slight modifications, developed by the Forest Ecosystem Management Assessment...
Despite the dissemination of comprehensive reviews and teacher-friendly resources describing evidence-based practices to improve student outcomes, the adoption of these practices is slow and inconsistent across instructors at colleges and universities. To help reduce this research-practice gap, I argue for the application of implementation science to teaching and learning research...
In 2007, the Oregon Wave Energy Trust (OWET) put out a request for proposals
to begin to discover answers to many of the environmental and human dimensions
questions. A multidisciplinary group of social scientists – Flaxen Conway, Brent Steel,
Michael Harte, and Bryan Tilt, Oregon State University – responded to...
