If you build it, will they come? Evolution towards the application of multi-dimensional GIS to fisheries-oceanography

Creator:: Vance, Tiffany C.
Abstract:: The development of new technologies in science is a balance between existence and use. There are three versions of this duality – something is built and users come, something is built and users don’t come, and, finally, potential users show up but the ballpark has not yet been built. In...

Designing and understanding information retrieval systems using collaborative filtering in an academic library environment

Creator:: Jung, Seikyung
Abstract:: Accessing information on the Web has become ingrained into our daily lives, and we seek information from many different sources, including conference and journal publications, personal web pages, and others. Increasingly, web-based information retrieval systems such as web-based search engines, library on-line catalog systems, and subscription-based federated search systems are...

Traditional ecological knowledge to develop and maintain fire regimes in northwestern California, Klamath-Siskiyou bioregion : management and restoration of culturally significant habitats

Creator:: Lake, Frank K.
Abstract:: The use of Native American fire regimes evolved in the Klamath-Siskiyou bioregion over millennia. A mixture of Native American and Euro-American socio-cultural management has developed from adaptations to climate, topography, ecological processes, and land use practices. This research incorporates Traditional Ecological Knowledge (TEK) to partially examine the role of tribal...

A new technique for high performance tandem time-of-flight mass spectrometry

Creator:: Katz, Daniel Louis
Abstract:: The main result of this written dissertation is a mathematical solution to the problem of multiplex recording for high performance tandem time-of-flight mass spectrometry. The prescription is to use a time-lag accelerator in the second stage to match the ion optical properties of the decay fragments to the requirements of...

Electric utility pole yard training facility : Designing an effective learning environment

Creator:: Topping, Robert P.
Abstract:: The primary responsibility of electric utilities is to supply consistent, dependable, and affordable energy to private customers, businesses, and industries. As with many businesses, electric utilities are experiencing the effects of an aging workforce and expending considerable resources to train their current and replacement workers. Community colleges can partner with...

Secondary mathematics preservice teachers' development of technology pedagogical content knowledge in subject-specific, technology-integrated teacher preparation program

Creator:: Suharwoto, Gogot
Abstract:: The purpose of this study was to describe the development of mathematics preservice teachers’ technology pedagogical content knowledge (TPCK) in a subject specific, technology integrated teacher preparation program. The study also investigated the roles of several influential components of the program and the technology thread throughout the program in supporting...

Chronobiology of garter snakes : environmental and hormonal mechanisms mediating hibernation and reproduction

Creator:: Lutterschmidt, Deborah I.
Abstract:: Most vertebrates exhibit seasonality in many life history traits. Such seasonal rhythms are temporally organized via the transduction of environmental cues (e.g., photoperiod, temperature) into appropriate endocrine signals. However, among ectothermic vertebrates that undergo continuous winter dormancy, temperature is the only environmental cue available for synchronizing seasonal rhythms. Most intriguing...

Indirect effects of ultraviolet-B radiation on larval amphibians as mediated by food quality and trophic interactions

Creator:: Scheessele, Erin A.
Abstract:: Ultraviolet-B radiation (UVB) is an abiotic stressor in both terrestrial and aquatic systems. The stratospheric ozone layer, depleted due to anthropogenic activities and the cause of elevated UVB at earth's surface over the last four decades, is predicted to recover by 2065. However, UVB levels in aquatic systems may continue...

Influences of high severity fire and postfire logging on avian and small mammal communities of the Siskiyou Mountains, Oregon, USA

Creator:: Fontaine, Joseph B.
Abstract:: High severity fire is a historical and integral disturbance process in coniferous forest types. Compounded disturbances such as multiple fires or post-disturbance management activities are increasingly common, but ecological responses are not well understood and may represent novel types of disturbances. I studied bird and small mammal communities in the...

Effects of esfenvalerate on native macroinvertebrates representative of Pacific Northwest streams

Creator:: Johnson, Katherine R.
Abstract:: Aquatic insects are essential components of healthy stream ecosystems, contributing to nutrient cycling, trophic dynamics and other ecological functions. Aquatic insect species, particularly those in the orders Ephemeroptera, Plecoptera and Trichoptera (EPT taxa) are however, extremely sensitive to insecticide contamination. Given that urban and agricultural use of synthetic pyrethroid insecticides...
