In this dissertation, the spectroscopic properties and thermodynamic stability of a class of materials known as metal oxo and hydroxo clusters are studied. In aqueous solutions, many metals can aggregate into discrete clusters of metals bridged by oxo or hydroxo ligands. These clusters are of particular interest to us for...
Developed coastlines provide a variety of recreation opportunities to coastal residents and visitors but are also the first line of defense for oceanfront development against chronic hazards like erosion and sea level rise. In the Pacific Northwest of the United States, oceanfront homes also face an additional severe but very...
Forest Vegetation Management (VM) is an important tool used in the Pacific Northwest (PNW) for reforestation. It has been well documented that VM increases seedling survival and crop tree volume growth. What is less understood, is how altering the plant community and successional trajectory affects the way the ecosystem uses...
Water conservation and water quality are rapidly increasing in importance in all areas of the world. The ability to accurately measure soil water content and salinity, over a wide variety of conditions, is key to meeting this need. A set of forward prediction models and waveform interpretation algorithms to extract...
This research employed both quantitative and qualitative research methodologies to
explore the impact of mobile wireless technology (MWT) in higher education classrooms.
The methodology was developed using systems engineering concepts. A methodology to
evaluate and compare the cost, cost-effectiveness and cost-utility of different MWT
configurations was also developed. Five outcomes...
Instruction in a University Honors College was evaluated using Small Group Instructional Diagnosis (SGID), a qualitative evaluation process. Fifty-one class sections were evaluated over a three-year period to determine what worked to help students learn, what did not work, and suggestions for improvement. Seven instructors used both SGID and an...
A method was developed for converting the food producing capabilities
of Oregon's soils to numerical data from which state and county
carrying capacities for human populations could be calculated. Another
method was developed for converting the needs for housing and related
support construction to numerical data which would consume cultivated...
