Mortality Associated with Short- and Long-Term Temperature Changes: A Global Evaluation within the Prospective Urban Rural Epidemiology Study

Creator:: Bigouette, John P.
Abstract:: The influence of increasing temperatures on human health has been widely established across multiple health disciplines. Short-term temperature changes are associated with an increased risk of hospitalization and death overall and in a variety of health conditions, such as cardiovascular disease. Even as humans can self-regulate heat stresses, the elderly,...

Forms of Life: Goethe’s Impact on Twentieth-Century Anglophone Botany and Morphology

Creator:: Hahn, Andre M.
Abstract:: This dissertation examines the impact of the German naturalist and literary figure Johann Wolfgang von Goethe’s ideas on twentieth century Anglophone plant morphology and biology. Goethe interpreted the organ forms of flowering plants as metamorphoses of each other. His literary, historical, and philosophical writings suggest themes of alienation from and...

Undergraduate Research as a Tool to Promote Diversity, Equity, and Success in STEM: Exploring Potential Barriers and Solutions to Access for Students from Historically Underrepresented Groups

Creator:: Pierszalowski, Sophie P.
Abstract:: In response to concern over a lack of diversity in STEM postsecondary programs, institutions of higher education across the nation have promoted opportunities for undergraduate research. Such opportunities have been shown to enrich student experiences and success, especially for students from historically underrepresented groups. While these benefits have been fairly...

Processing and functional diversity of plant microRNA

Creator:: Cuperus, Josh
Abstract:: RNA interference pathways can involve amplification of secondary siRNAs by RNA-dependent RNA polymerases. In plants, RDR6-dependent secondary siRNAs, including transacting siRNAs (tasiRNAs), arise from transcripts targeted by some microRNAs (miRNAs). In the case of TAS3 tasiRNA formation, ARGONAUTE7 (AGO7)-miR390 complexes interact with primary transcripts at two sites, resulting in recruitment...

Supporting Learning and Thinking with Multiple Representations in Upper Division Physics Courses

Creator:: Alfson, Jonathan W.
Abstract:: Physicists solve problems and communicate their work using many external representations, such as equations, words, diagrams, graphs, sketches, pictures, and more. To learn physics, then, students must learn to use external representations. In this dissertation, I present three manuscripts. Each manuscript discusses how upper-division Paradigms in Physics students use multiple...

Modeling Forest Response to Changing Climate Conditions in Western North America

Creator:: Hawkins, Linnia R.
Abstract:: Forests play an integral role in the global carbon cycle, regulating the atmospheric CO₂ concentration by sequestering nearly one third of anthropogenic carbon emissions and storing carbon for centuries. Forest ecosystems are integrated into the culture, ecology, and economy of western North America, supporting wildlife habitat, local economies, recreation, and...

Life history and environmental influences on avian incubation and parental care in songbirds

Creator:: Austin-Bythell, Suzanne H.
Abstract:: Patterns of nest attendance behavior by breeding birds represent a parent-offspring trade-off in which adults balance self-maintenance with parental care decisions. Incubation, in particular, is of interest because adults must provide an environment suitable for embryonic development through nest-building and contact-incubation. We evaluated how adult incubation constancy and nest visitation...

An investigation into modeling snow cover elements at Crater Lake National Park and surrounding environs as an improved "ground truth" method for satellite snow observations

Creator:: Hamilton, William L.
Abstract:: Streamflow forecasts are essential to the optimal operation of hydroelectric and irrigation reservoirs in the Pacific Northwest. Satellite snow cover observations would aid in these streamflow forecasts by providing snow cover data at regular time intervals. Unfortunately, satellite capability to remotely sense mountain snow cover conditions is indeterminate due to...

Endogenous and antiviral RNA silencing pathways in Arabidopsis

Creator:: Chapman, Elisabeth J.
Abstract:: RNA silencing pathways are required for a wide variety of processes in most eucaryotes. In plants, small-interfering RNA (siRNA) arising from transposons and other repetitive sequences is associated with heterochromatin formation and maintenance. MicroRNAs and trans-acting siRNAs encoded at discrete loci function as negative regulators of gene expression by triggering...

Comparing lifespan and life course perspectives on combat exposure and PTSD symptoms in later life : findings from the normative aging study

Creator:: Kang, Sungrok
Abstract:: We examined how the experiences of World War II and Korean War veterans, including prewar, warzone, and postwar factors, affected PTSD symptoms in later life. This dissertation consists of two studies. In Study 1, four different hypotheses from a lifespan approach were examined (King et al., 1996): stress evaporation (only...
