We have mapped a recently active left-lateral strike-slip fault (the Wecoma fault) on the floor of Cascadia Basin west of the Oregon convergent margin, using SeaMARC I sidescan sonar, Seabeam bathymetry and multichannel seismic and magnetic data. The fault intersects the base of the continental slope at 45°10’N and extends...
This thesis explores how students can find Shakespeare relevant in this modern technological society by creating and editing two podcasts that summarize two well known Shakespeare plays, Romeo and Juliet and A Midsummer Night’s Dream. Interviews are also included from Oregon State University students to see their perspectives from reading...
Iodine-129 is a key risk driver at sites where nuclear materials have been fabricated or processed, and it is a predominant isotope of concern in long-term waste storage strategies. I-129 exists primarily as iodate in the subsurface at the Hanford Site in south-central Washington State. Between 15 and 40% of...
The purpose of this descriptive case study analysis was to provide portraits of the heuristics students used and difficulties they encountered solving conditional probability problems prior to and after two-week instruction on sample space, probability, and conditional probability. Further analysis consisted of evaluating the data in relation to a previously...
In recent years, the field of videography (the process of obtaining
video imagery) has taken on greater significance in remote sensing
applications. Today studies are being conducted to determine the potential
uses and capabilites of airborne video imagery. In the past, satellite or aerial
photography analysis and interpretation has been...
The purpose of this descriptive case study analysis was to provide portraits of the methods college students used to solve probability problems and the factors that supported or impeded their success prior to and after two-week instruction on probability. Fourteen-question Pre- and Post-Instructional Task-Based Questionnaires provided verbal data of nine...
The Oregon Long-Term Soil Quality Project was initiated to identify soil
properties that respond rapidly to alternative management practices. Such practices
included winter cover cropping, which was implemented at two experimental research
stations and several grower fields throughout the Willamette Valley. The goal of this
thesis was to identify the...
Natural Douglas-fir stand development is the result of
many types of disturbance, both natural and management
induced. The magnitude and timing of these disturbances
have profound effects on the structure and composition of
both the overstory and understory plant communities. Vine
maple responds to disturbance by basal sprouting, layering,
producing...
The purpose of this dissertation was to explore the developmental experience of novice play therapists. A review of the play therapy training literature as well as the counselor development literature suggested that there are characteristics such as patience, flexibility, and a love for children that are needed to work with...
