Applying a Dynamic Time Warping Approach to Stratigraphic Correlation: Quaternary Magnetostratigraphy and Ediacaran–Cambrian Chemostratigraphy

Creator:: Hagen, Cedric J.
Abstract:: Magneto- and chemostratigraphic correlation underpins much of our understanding of Earth history, yet typical correlation techniques are neither quantitative nor objective. Within this dissertation, I detail my efforts to develop and apply dynamic programming-based algorithms that accomplish optimal and reproducible stratigraphic alignment. I apply these algorithms to three geologic intervals:...

Life history variables of Dicamptodon salamanders

Creator:: Wagner, Lisa A.
Abstract:: It is good practice to fully understand components of an ecosystem if we hope to preserve its biodiversity. A problem is that we know very little about some organisms and nothing of others. Studies that investigate an organism’s basic biological, ecological and physiological life history variables advance our knowledge of...

An Assessment of the “Sweating Sickness” Affecting England During the Tudor Dynasty

Creator:: Wollert, Edwin Del
Abstract:: While historiography and interest in Tudor England at both the popular and specialist levels presents few signs of diminishing, there may nonetheless exist a sense that we have little left to learn about this period and its culture. A notable gap in our knowledge, however, remains regarding the mysterious disease...

ALS-inhibitor resistant downy brome (Bromus tectorum L.) biotypes in Oregon : Mechanism of resistance, fitness, and competition

Creator:: Park, Kee-Woong
Abstract:: Understanding the mechanism of resistance, relative fitness and competitiveness of herbicide resistant biotypes is important to predict population dynamics and to establish resistance management strategies. This study was conducted to determine the level of resistance to acetolactate synthase (ALS) inhibitors and the mechanism of resistance of ALS-inhibitor resistant downy brome...

Classifying the toxicity of pesticides to honey bees via support vector machines with random walk graph kernels

Creator:: Yang, Ping
Abstract:: Pesticides benefit agriculture by increasing crop yield, quality, and security. However, pesticides may inadvertently harm bees, which are valuable as pollinators. Thus, candidate pesticides in development pipelines must be assessed for toxicity to bees. Leveraging a data set of 382 molecules with toxicity labels from honey bee exposure experiments, we...

Aquatic Ecology in Coastal Riverscapes : Characterizing Fish Assemblages and Stream Chemistry over Time

Creator:: Feiten, Nicole E.
Abstract:: Recreational and Commercial fisheries and the quality of aquatic habitats in which the fish live are an important part of the livelihoods and economy of the Oregon Coast. The composition of important juvenile fish assemblages in estuaries can bring a unique view into the needs of different species on a...

Plague in London : a case study of the biological and social pressures exerted by 300 years of yersinia pestis

Creator:: Hall, Alice
Abstract:: The Second Pandemic had a profound impact on the people of Europe. In the few years between 1347 and 1350, a new epidemic disease spread across the entirety of Europe and killed between one third and two thirds of the population. While this initial wave was important, the real significance...

Limiting Behavior of Stochastic Processes Involving Martingale Structures

Creator:: Mukherjee, Arpita
Abstract:: A stochastic process is given by a family of random variables indexed by elements of a set. We have considered stochastic processes of three different types, each involving an associated martingale structure. Martingale is a sequence of random variables for which the conditional expectation at a certain time point given...

Plot-Scale Field Investigation : Characterizing Water Motion in Sandy Agricultural Soils

Creator:: Nolasco, Stephanie M.
Abstract:: Irrigated agricultural production in sandy soils presents several unique challenges to growers, including naturally high permeability, low native water retention, as well as high rates of water drainage losses and leaching of chemicals to the shallow aquifers. This study is an initial investigation into water motion in the sandy agricultural...

'Reclaiming Voice : Enacting Social Discourse Communities in Belizean First-Year College Composition'

Creator:: Habet, André Antonio
Abstract:: This thesis explores the evolving purposes for the teaching of first-year English composition in Belize. Starting from an analysis of the underlying cultural assumptions of U.S. composition pedagogies, this thesis argues that American composition pedagogies need to be rethought when applied in a Belizean context to fulfill the country's unique...
