Eastward Routing of Glacial Lake Agassiz Runoff caused the Younger Dryas Cold Event

Creator:: Leydet, David J.
Abstract:: The purpose of this thesis is to analyze an abrupt case of climate change in the past as a means to understand the mechanisms that force climate change. By looking to past analogs of climate change, we hopefully will gain an understanding of these events, which could be used to...

The role of costimulation and adjuvants in the development of T cell effector and memory responses

Creator:: Maxwell, Joseph R.
Abstract:: T cells are one of the key cells in the immune system. Although they are not the first line of defense against a pathogen, their functions can greatly enhance the phagocytosis and destruction of pathogens as well as the development of antibody responses. Furthermore, even when responding T cells have...

Deciphering Quaternary Geomagnetic, Glacial, and Depositional Histories Using Paleomagnetism in Tandem with Other Chronostratigraphic and Sedimentological Approaches

Creator:: Reilly, Brendan T.
Abstract:: Stratigraphy and chronology are essential to sedimentological study of Earth system histories. And, stratigraphy and chronology are often challenging and interesting problems themselves. The Quaternary (2.588 Ma - present) experienced paleoenvironmental and paleo-geomagnetic variability well outside the range of the recent instrumental record, providing the opportunity to place recent observations...

Development of organocatalyzed, intramolecular heteroatom Michael addition and application towards alkaloid synthesis

Creator:: Carlson, Erik
Abstract:: Effective methods for the enantiopure formation of substituted piperidine rings are significantly important due to their presence in alkaloid products. A valuable method to form these ring systems would be via an intramolecular heteroatom Michael addition from the corresponding enone or enal. Described herein is a methodolgy that has been...

Dynamics of the Laurentide Ice Sheet

Creator:: Carlson, Anders Eskil
Abstract:: This dissertation concentrates on the controlling factors on the instability of the Laurentide Ice Sheet (LIS) and their effects on abrupt climate change. Northern Hemisphere climate fluctuated abruptly during the last deglaciation possibly related to variability in Atlantic meridional overturning circulation (AMOC) and reduced aerial extent of the LIS. Reductions...

Using systematic evidence review to inform family forest owner educational program development

Creator:: Carlson, Lisa D.
Abstract:: Purpose: Natural resources education and extension is at the intersection of diverse disciplines, where effective practice and policy decisions rely on the impartial evaluation and synthesis of multiple sources of information. This investigation examines contemporary information sources describing attributes of Oregon family forest owners, with the objectives of identifying potential...

RTFM NOOb: Criticizing Internet Based Instructional Documents as a Rhetorical Genre

Creator:: Carlson, Gordon S. III
Abstract:: The purpose of this thesis is to aid in qualitative improvements to technical support documents on the Internet. By using a generic criticism this analysis will make substantive suggestions towards the improvement of this type of document by engaging the rhetoric employed by their authors. It will discuss the history...

Assessing the impact that professional development training has on the self-efficacy of school counselors, including rural school counselors

Creator:: Millmore, Patrick J.
Abstract:: Boyd and Walter (1975) identified the need to provide supervision for school counselors almost forty years ago. Michelle Obama, the First Lady of the United States (2014), in her address at the American School Counselor Association Conference stated that school counselors needed to be provided with professional development opportunities designed...

A 37,000-year record of paleomagnetic and environmental magnetic variability from Burial Lake, Arctic Alaska

Creator:: Dorfman, Jason Michael
Abstract:: Burial Lake sediments from the Noatak Basin in the northwest Brooks Range of Arctic Alaska (68.43°N, 159.17°W, 21.5 m water depth) provide the oldest continuous lacustrine record of paleo-environmental change and paleomagnetic secular variation (PSV) in eastern Beringia. A precise radiocarbon chronology, determined through accelerator mass spectrometry (AMS) allows us...

Particulate Trace Metal Fluxes in the Western Arabian Sea and Their Links to Marine Productivity

Creator:: Flannery, Kelly M.
Abstract:: Many trace elements (e.g., Zn, Cd, Mo) are essential phytoplankton micronutrients, making them crucial to the marine ecosystem and ultimately the carbon cycle. Because of this association trace metals are also utilized in paleoceanographic studies (e.g., Mo, Cd). However, not much is known about what controls the cycling of these...
