Changing student learning approaches in fundamental accounting education through the use of graphic organizers

Creator:: Fisher, Paul A.
Abstract:: The field of accounting has experienced dramatic changes in the past 20 years. Advances in technology and workplace requirements have changed the responsibilities in the accounting position of a historical recorder to a functioning manager within the organization. The curriculum used by accounting instructors has not changed or kept pace...

Hydrogen isotopic composition of C₃₇ alkenones and the ecology and physiology of coccolithophores

Creator:: Wolhowe, Matthew D.
Abstract:: A three-part study was conducted into the impact of physiological and ecological variables on the net isotopic fractionation of hydrogen, α[subscript K₃₇], expressed in C₃₇ alkenones. First, alkenone-producer production, abundance, and export were characterized in the summertime Gulf of California and Eastern Tropical North Pacific using compound-specific, labeled in situ...

The atmospheric chemistry of particulate-bound polycyclic aromatic hydrocarbons : concentration, prediction, laboratory studies, and mutagenicity

Creator:: Jariyasopit, Narumol
Abstract:: The trans-Pacific atmospheric transport of particulate matter (PM)-bound polycyclic aromatic hydrocarbons (PAHs) to remote sites in western North America has been well documented and has triggered research questions regarding to atmospheric transformation of PM-bound PAHs and the potential impacts on human health from their inhalation exposure. In this dissertation, field...

Seasonality of U[superscript K’]₃₇ temperature estimates as inferred from sediment trap data

Creator:: Rosell-Melé, Antoni and Prahl, Fredrick G.
Abstract:: The seasonality of sea surface temperatures (SST) estimated from the alkenone-U[superscript K’]₃₇ index has been a debated issue since the development of the sediment trap time series data from 34 sampling locations, we show that the maximum alkenone flux in sediment traps varies markedly across the oceans, only on latitude...

Half Array Architecture for Advancing Microchannel Heat Recuperation to Market

Creator:: Brannon, Samuel T.
Abstract:: High temperature microchannel heat recuperators (HTμRs) offer an efficient means of improving reactor process thermal efficiency by offering smaller form factors due to increased heat transfer surface area density and volumetric heat transfer rate over traditional heat exchanger designs. To date, HTμRs face cost and reliability challenges. In this work,...

Assessing the role of reactive metal species in soil organic matter cycling using chemical imaging

Creator:: Keiluweit, Marco
Abstract:: Intimate associations with reactive metal species permanently protect soil organic matter (SOM) from microbial access and oxidation, contributing to the build-up of organic carbon (C) stocks in soils. It is increasingly recognized, however, that such associations can be reversible and that reactive metal species might even facilitate the oxidation of...

Myrionecta rubra population genetic diversity and its cryptophyte chloroplast specificity in recurrent red tides in the Columbia River estuary

Creator:: Herfort, Lydie, Peterson, Tawnya D., McCue, Lee Ann, Crump, Byron C., Prahl, Fredrick G., Baptista, Antonio M., Campbell, Victoria, Warnick, Rachel, Selby, Mikaela, Roegner, G. Curtis, and Zuber, Peter
Abstract:: For several decades, annually recurring blooms of the photosynthetic ciliate Myrionecta rubra have been observed in the Columbia River estuary in late summer. In an effort to understand the dynamics of these blooms, we investigated the genetic variability of M. rubra and its cryptophyte plastids within 3 large estuarine blooms...

Development of baseline data on Oregon's high desert vernal pools

Creator:: Wyland, Sara Alice
Abstract:: Vernal pools are ephemeral surface water wetlands with unique hydrology, ecology and species composition. Rare and endemic species rely on vernal pool habitat due to specialization traits the species possess because they are adapted to the extreme conditions. Many vernal pool basins have been topographically and hydrologically altered and are...

Studies toward the total synthesis of azaspiracid-1

Creator:: Kuiper, Damien L.
Abstract:: Azaspiracid has generated an enormous amount of scientific interest in the fourteen years since its initial discovery. The structure contains a 6,5,6 bis-spiroketal, a [3.3.1] bicyclic ketal and a 6,5-spiroaminal linkage as key moieties. With 9 rings, 20 stereocenters and three alkenes, the azaspiracid immediately attracted the interest of the...

Infrastructure for collaborative science and societal applications in the Columbia River estuary

Creator:: Baptista, António M., Seaton, Charles, Wilkin, Michael P., Riseman, Sarah F., Needoba, Joseph A., Maier, David, Turner, Paul J., Kärnä, Tuomas, Lopez, Jesse E., Herfort, Lydie, Megler, V. M., McNeil, Craig, Crump, Byron C., Peterson, Tawnya D., Spitz, Yvette H., and Simon, Holly M.
Abstract:: To meet societal needs, modern estuarine science needs to be interdisciplinary and collaborative, combine discovery with hypotheses testing, and be responsive to issues facing both regional and global stakeholders. Such an approach is best conducted with the benefit of data-rich environments, where information from sensors and models is openly accessible...
