The influence of early diagenesis on trace element and molybdenum isotope geochemistry

Creator:: Poulson, Rebecca L.
Abstract:: This thesis investigates the influence of early diagenesis on trace metal and molybdenum isotope behavior in marine and lacustrine environments. Chapter one is a synthesis of previous research in all the marine environments investigated, providing an essential geochemical context for interpreting the observed behavior of Mo in these settings. Chapter...

Hotspots of deep ocean mixing on the Oregon continental slope

Creator:: Nash, Jonathan, Alford, M. H., Kunze, E., Martini, K., and Kelly, S.
Abstract:: Two deep ocean hotspots of turbulent mixing were found over the Oregon continental slope. Thorpe-scale analyses indicate time-averaged turbulent energy dissipation rates of ε > 10⁻⁷ W/kg and eddy diffusivities of Kp ~ 10⁻² m²/s at both hotspots. However, the structure of turbulence and its generation mechanism at each site...

An alternative architecture for performing basic computer arithmetical operations

Creator:: Djang, Kevin
Abstract:: The arithmetic portions of almost all modern processor architectures are of very similar design. We use the term "traditional" to describe this design, the primary characteristics of which are native support for integer and floating-point number types and special disjoint instructions and hardware for each supported type. Decades of refinement...

Diffuse deformation patterns along the North American plate boundary zone, offshore western United States

Creator:: Chaytor, Jason D.
Abstract:: Plate boundaries are commonly regions of complex, diffuse deformation with the motion across the boundary accommodated by numerous structural systems, rather than being narrow, discrete zones of deformation. One such boundary occurs where the North American plate makes contact with Juan de Fuca, Gorda, and Pacific plates along the west...

Pollination and pollinators of pumpkin and squash (Cucurbita maxima Duchesne) grown for seed production in the Willamette Valley of western Oregon

Creator:: Gavilánez-Slone, Jenny M.
Abstract:: 'Golden Delicious' winter squash (GDWS), Cucurbita maxima Duchesne, provides significant amounts of pollen (24 mg) and nectar (236 μl), but with a low reward of 14% nectar sugar. The quantity of nectar produced per GDWS flower differed between sites and floral sex. The GDWS male flowers had 25% higher sugar...

Evaluating space use and pesticide exposure risk for burrowing owls in an agricultural environment

Creator:: Gervais, Jennifer A.
Abstract:: Large burrowing owl (Aihene cunicularia) populations exist in areas of intensive agriculture in California, and pesticide exposure has been identified as a potential threat to population persistence. I evaluated breeding season use of agricultural fields by adult male owls using radio telemetry, and examined egg contaminant residues to estimate population-level...

A cost effectiveness analysis of anthelminthic intervention for community control of Ascariasis : traditional vs. pharmaceutical therapy

Creator:: Ortega, Fernando
Abstract:: A Cost-Effectiveness Analysis of a targeted intervention for community control of Ascariasis was carried out in three rural communities near Quito, Ecuador. Targeted treatment with Paico (Chenopodium ambrosioides) and Albendazole (ABZ) was applied to children aged 5 to 15 years attending primary local schools in Aglla, Checa and Iguinaro. Prevalence...

Middle school teachers’ use of a formative feedback guide in mathematics problem solving instruction

Creator:: Strowbridge, Jessica
Abstract:: The purpose of this study was to address the implementation fidelity of one part of a professional development model developed by the Northwest Regional Educational Laboratory (NWREL). Specifically, this research investigates middle school teachers’ use of a formative feedback guide developed by NWREL staff, examining the reliability with which teachers...

Investigating the validity of the Washington State performance-based pedagogy assessment process for teacher licensure

Creator:: Tisadondilok, Sita
Abstract:: This study examined the validity of the WA PPA process which was developed to assess teacher candidates for licensing purposes. Three validities were investigated using Messick’s view. Content validity was addressed using the raters’ judgment to establish alignment between the WAC standards and the INTASC. Evidential validity refers to the...
