Oregon Relational Spatial Topology (ORST) Representation

Creator:: Hunt, David
Abstract:: We designed a concise way to store and manipulate GIS coverage data in a geospatial database. Our geospatial database is implemented with PostgreSQL and PostGIS. PostgreSQL is an object-relational database, and PostGIS supports various geospatial operations as an SQL extension. In our Oregon Relational Spatial Topology (ORST) approach, topological relationships...

Teacher Math Anxiety and Math Instructional Time

Creator:: Morton, Heidi L.
Abstract:: The scientific way of knowing, which results in tremendous advancements in our society, heavily depends on the use of mathematics. Given that math touches nearly every aspect of peoples’ lives in different ways, it is critical that today’s students and tomorrow’s citizens have a solid understanding of math. Unfortunately, a...

Prevalence of Mathematics Anxiety in Preservice Teachers and Preservice Counselors

Creator:: Gill, Gurpal K.
Abstract:: Almost two decades have passed since the publication of Jackson and Leffingwell’s (1999) influential article on math anxiety in preservice school teachers and their worst math experiences. The present dissertation represents both a replication and an extension of the original study. Study Arm A was the replication study with preservice...

Quantitative Study of Math Excel Calculus Courses

Creator:: Watkins, Christopher H.
Abstract:: About twenty years ago, a large, rural, doctoral granting institution with an undergraduate population of approximately 24,000 in the pacific northwest of the United States established the Math Excel program. Students would attend lectures three times a week for 50 minutes like a traditional course, and they would also attend...

Aquatic Invasions! A Menace to the West : How long can zebra mussels survive out of water? A math model!

Creator:: Siemens, Tania
Abstract:: Students use an online quarantine estimator to determine how long zebra mussels can survive out of water. By varying the settings, such as location in country and month of the year, students can observe how the time needed to dry a boat is related to the time of year and...

Spatial Patterns of Chemical Weathering at the Basal Tertiary Nonconformity in California from Multispectral and Hyperspectral Optical Remote Sensing

Creator:: Sousa, Francis J. and Sousa, Daniel J.
Abstract:: Visible through shortwave (VSWIR) spectral reflectance of the geologic units across the basal Tertiary nonconformity (BTN) is characterized at three spatially disparate locations in California. At two of these sites, location-specific spectral endmembers are obtained from AVIRIS imaging spectroscopy and linear spectral mixture models are used to visualize spatial patterns...

Early Math Enrollment in Washington State Community Colleges

Creator:: Harri, Ed J.
Abstract:: More than half of students in Washington state community colleges enroll in developmental mathematics, but a relatively small percentage of these students persist to the second year. Many students place into these courses and never enroll; others enroll at some point after the first academic term, even when faced with...

Hatfield Marine Science Center Dynamic Revetment Project DSL permit # 45455-FP: Monitoring Report, February 2015

Creator:: Cowen, Robert, Nelson, Walt, Arbuckle, Scarlett, and Folger, Christina
Abstract:: Stabilization of the Yaquina Bay shoreline along the northeastern edge of the Hatfield Marine Science Center (HMSC) campus became necessary to halt erosion that threatened both HMSC critical infrastructure (seawater storage tank) and public access to the HMSC Nature Trail. A Dynamic Revetment (gravel beach) was installed in November, 2011...

Improving wear time compliance with a 24-hour waist-worn accelerometer protocol in the International Study of Childhood Obesity, Lifestyle and the Environment (ISCOLE)

Creator:: Tudor-Locke, Catrine, Barreira, Tiago V., Schuna, John M., Jr., Mire, Emily F., Chaput, Jean-Philippe, Fogelholm, Mikael, Hu, Gang, Kuriyan, Rebecca, Kurpad, Anura, Lambert, Estelle V., Maher, Carol, Maia, José, Matsudo, Victor, Olds, Tim, Onywera, Vincent, Sarmiento, Olga L., Standage, Martyn, Tremblay, Mark S., Zhao, Pei, Church, Timothy S., Katzmarzyk, Peter T., and ISCOLE Research Group
Abstract:: BACKGROUND: We compared 24-hour waist-worn accelerometer wear time characteristics of 9-11 year old children in the International Study of Childhood Obesity, Lifestyle and the Environment (ISCOLE) to similarly aged U.S. children providing waking-hours waist-worn accelerometer data in the 2003-2006 National Health and Nutrition Examination Survey (NHANES). METHODS: Valid cases were...

An experimental investigation of natural convection heat transfer from vertical flat plates in mercury

Creator:: White, Donald Henry
Abstract:: Heat transfer from a vertical flat plate in an infinite pool of mercury was investigated. Velocity profiles were measured with a hot-film anemometer and simultaneous temperature profiles measured with thermocouples in this low Prandtl number liquid metal. Constant heat flux plates at Grashof numbers of 9 x 10⁸ and 4...
