An emerging role for the exocyst : plant morphogenesis

Creator:: Cole, Rex A.
Abstract:: Plants develop a vast array of cell shapes and sizes by selectively modifying their surrounding cell walls to expand in some regions and not in others. This process of morphogenesis requires the delivery of secretory vesicles to specific locations at the cell periphery, where exocytosis adds new membrane and proteins...

New insights into the biology of theropod dinosaurs

Creator:: Quick, Devon E.
Abstract:: There is little, if any, direct fossil evidence of the cardiovascular, respiratory, reproductive or digestive biology of dinosaurs. However, a variety of data can be used to draw reasonable inferences about the physiology of the carnivorous theropod dinosaurs (Archosauria: Theropoda). Extant archosaurs, birds and crocodilians, possess regionally differentiated, vascularized and...

John Archibald Wheeler : a study of mentoring in modern physics

Creator:: Christensen, Terry M.
Abstract:: This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body...

Relations of appraised stress, coping strategies, and negative affect among college students : a structural equation modeling approach

Creator:: Eisenbarth, Christopher A.
Abstract:: College is recognized by many researchers to be an exceptionally stressful period of development. Despite considerable theoretical and empirical attention, many questions still remain regarding the experience of stress among college students. There is a dearth of multivariate investigations in this area and, to date, no clear consensus exists among...

Trophic dynamics of marine nekton and zooplankton in the Northern California Current ecosystem

Creator:: Miller, Todd William
Abstract:: The Northern California Current (NCC) ecosystem exhibits extreme seasonal, interannual and interdecadal shifts in the abiotic environment and shifts in primary and higher production. This variability is also apparent in the spatial structure of the ecosystem with nearshore-shelf waters (<150 m isobath) being highly productive and having a different community...

Inside a school-university partnership : Participation in a community of practice as professional growth

Creator:: Bottoms, SueAnn I.
Abstract:: Research suggests that long-term participation in professional development is critical in helping teachers meet the increasing demands of reform efforts and changing practice (Gallucci, 2003; Darling-Hammond, 1995; Little, 1993). Understanding the influence that participation in a community of teachers as a community of practice may have on teachers’ professional growth...

The influence of early diagenesis on trace element and molybdenum isotope geochemistry

Creator:: Poulson, Rebecca L.
Abstract:: This thesis investigates the influence of early diagenesis on trace metal and molybdenum isotope behavior in marine and lacustrine environments. Chapter one is a synthesis of previous research in all the marine environments investigated, providing an essential geochemical context for interpreting the observed behavior of Mo in these settings. Chapter...

Environmental effects on heartwood extractive content and their consequences for natural durability in Douglas-fir and western redcedar

Creator:: Taylor, Adam McVaugh, 1969-
Abstract:: Heartwood can have properties that are distinct from sapwood, including resistance to insect and microbial attack. Despite the practical importance of heartwood formation in trees, a review of the literature revealed that little was known about the effects of environmental factors on heartwood quality or how variations in heartwood properties...

The great fires : Indian burning and catastrophic forest fire patterns of the Oregon Coast Range, 1491-1951

Creator:: Zybach, Bob
Abstract:: The purpose of this study is to examine the relationship between land management practices of Indian communities prior to contact with Europeans and the nature or character of subsequent catastrophic forest fires in the Oregon Coast Range. The research focus is spatial and temporal patterns of Indian burning across the...

Geneticist L.C. Dunn : politics, activism, and community

Creator:: Gormley, Melinda (Melinda Brooke)
Abstract:: L. C. Dunn (1893-1974) spent most of his scientific career conducting research in developmental genetics as a member of the Zoology Department at Columbia University in the City of New York. He had an accomplished scientific career researching mutations in mice, which earned him respect from other geneticists and scientists....
