State parks in Oregon provide important sites for visitor recreation and natural resource education. With the increasing number of visitors to Oregon coastal parks, tide pools and beach areas, there is growing need for site-specific marine education to enhance stewardship, interpretation and safety knowledge. The Oregon Sea Grant Program and...
Current state-of-the-art environmental, clinical, and in-vivo radiation sensing systems utilizing various inorganic and tissue-equivalent plastic scintillators are not user friendly, suffer from electron-beam-generated noise, and are difficult to deploy successfully for real-time dosimetry. A robust, real-time detection system using different scintillating materials coupled to solid-state detectors by optical fibers is...
This study examined the association between poverty and child neglect. The existence of a general association has been established for some time. However, there is much debate, and little detailed research, on the specific processes that create this association. This study focused on the form of neglect that involves the...
The evaluation of the stray-load losses in induction motors is an important part of the efficiency estimation process. However, stray-load losses have several components which are difficult to isolate and calculate. Consequently, they are more readily determined by test. IEEE Standard 112-1996 recommends the testing of electrical induction motors at...
This research project examines the growing informal sector of Ukrainian economy and the way global economic changes affect women's lives. It has been noticed by many Western researchers that women have been among the hardest hit by economic restructuring in Eastern Europe. Marginalization from the official labor force led a...
The Pacific salmonid species Oncorhynchus mykiss is separated into a migratory form (steelhead trout) and a
non-migratory form (rainbow trout). A decrease in water temperature is likely a cue triggering downstream
behavior in the migratory form, and testosterone inhibits onset of this behavior. To elucidate differences in
sensitivity to water...
The known distribution of beluga whales ranges from sub-Arctic to Arctic waters where they migrate in pods in response to environmental factors such as the presence of sea ice and prey. This study uses bivariate and multivariate analysis techniques to measure how environmental covariates are associated with the spatial-temporal distribution...
Oncorhynchus mykiss form partially migratory populations with anadromous fish that undergo marine migrations and residents that complete their life cycle in fresh water. Many populations’ anadromous components are threatened or endangered, prompting interest in understanding ecological and evolutionary processes underlying anadromy and residency. In this paper, we synthesize information to...
