Self-regulation in early childhood encompasses higher-order executive function processes and lower-order emotional responses that enable children to navigate the classroom environment. Although self-regulation and executive functions are overlapping constructs, self-regulation represents a broad assessment of children’s ability to call upon executive function processes in order to meet contextual demands. Prior...
Self-regulation skills lay the foundation for short- and long-term school success, and strengthening these skills in early childhood can have significant implications for immediate and future life outcomes (e.g., Blair & Diamond, 2008; McClelland, Acock, Piccinin, Rhea, & Stallings, 2013). A large body of literature has investigated how characteristics of...
The present study investigated the direct effects of residential mobility on children’s inhibitory control and academic achievement during the preschool year.

Participants included 359 preschool children (49% female) studied in the fall and...
The effect of sweeteners on fruit flavor perception was studied
through the use of fruitiness power functions for unsweetened and
sweetened model systems. In the first part of the study, two
isosweet concentrations of aspartame and sucrose were determined
and combined with five concentrations of orange and strawberry
flavorants. Fruitiness...
In Oregon, property tax revolts and school equalization measures have led to increasingly unstable and more non-discretionary public funding for schools. As a result, public schools are turning to private donations to provide both basic and supplemental educational opportunities. Some schools and districts are raising hundreds of thousands of dollars,...
Autonomous buoys were deployed in 2011 in the central Arctic: An Ice-Tethered Profiler (ITP) and Ice Mass Balance (IMB) buoys were deployed in the Makarov basin; a Polar Ocean Profiling System (POPS) and Ice Thickness (Ice-T) buoy were deployed on the Eurasian Basin. The two different sites were approximately 70km...
In winter and spring, ice-coast interactions driven by winds and ocean currents cause sea ice fractures (leads) to form repeatedly along Arctic coastlines. These events are often associated with rapid and expansive changes in sea ice drift and state that are challenging to predict and represent in models. We investigate...
Leads are long fractures wide enough for a ship to travel through the ice pack. Sea ice acts as a barrier between the ocean and the atmosphere, whereas leads allow the transfer of heat and moisture between the two. Leads play a role for marine mammals and are hunting grounds...
Pygmy rabbits (Brachylagus idahoensis) in Oregon and Washington are a sagebrush (Artemisia tridentata spp.) obligate species of concern because of declining populations and extirpation from much of their range. Efforts are underway to establish a captive bred population of the Columbia Basin pygmy rabbit in Washington state for reintroduction into...
Trichloroethene (TCE) is a common groundwater contaminant. Bioremediation, or the enhancement of natural microbial processes for the transformation of toxic compounds in soil and groundwater, is an effective solution to this widespread problem. The organisms that transform TCE in the subsurface are sensitive to environmental conditions, especially to the presence...

This dissertation is a compilation of three studies related to method development for the structural identification of emerging...
Research and public concern of poly and perfluoroalkyl substances (PFASs) as environmental contaminants has increased significantly due to the increasing number of reports of their detection in humans and wildlife. PFASs have a number of commercial applications including surfactants, coatings, polymers, and levelers, which are used on consumer products like...
Infestations of container nursery beds by Phytophthora spp. can be persistent and costly. One method of disinfestation that does not require the use of chemicals is soil solarization, which captures energy from the sun to heat soil and thermally inactivate target pathogens. In laboratory temperature gradient experiments, I investigated the...
Immune-mediated diseases are a frequent cause of morbidity and mortality in canine patients. Treatments currently involve generalized suppression of the immune system, and corticosteroids are often used as a first-line agent. While often effective, corticosteroids are unlikely to induce remission without substantial side effects. Second-line immunosuppressive agents may be effective...

Public attention and concern about per- and polyfluoroalkyl substances (PFASs) are increasing due to detection of PFASs in drinking water supplies, the environment, including remote locations, and wildlife and to the lowering of the federal health advisory levels of perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) in drinking water. Aqueous film-forming...
Aqueous film forming foams (AFFFs) are proprietary mixtures containing hydrocarbon surfactants and per-and polyfluoroalkyl substances (PFASs) that are used to extinguish hydrocarbon-based fuel fires. There is limited information on hydrocarbon surfactants in AFFFs and AFFF-contaminated groundwater even though they are more abundant (5-10% w/w) than PFASs (0.9-1.5% w /w) in...
To determine the impact of emerging environmental contaminants on human and environmental health, quantitative analytical methods are required. Analysis of emerging contaminants is hampered by their widely varying physical-chemical properties. Therefore quantitative analytical methods must be developed to determine the behavior of emerging contaminants in environmental systems.
A quantitative analytical...
Per- and polyfluoroalkyl substances (PFAS) are anthropogenic surfactants that have recently been identified as persistent organic pollutants.

Linear alkylbenzenesulfonate (LAS) is the most widely used anionic surfactant in
commercial detergent formulations. The environmental fate of LAS is of interest because
of its disposal to wastewater treatment facilities and subsequent occurrence as a
micropollutant in surface waters and groundwater. While LAS fate in wastewater
treatment systems and surface...
Phytophthora ramorum continues to cause extensive mortality of tanoaks in southwestern Oregon. Rain readily washes inoculum down through the canopy, causing new infections on the lower parts of the tree and neighboring host plants. Although this aspect of dispersal is well understood, the relative importance of infested soil and leaf...
Striga, a genus of obligate parasitic weeds in the family Orobanchaceae, has been

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...
Aqueous film-forming foams (AFFFs) are significant sources of per- and polyfluoroalkyl substances (PFAS) in the environment. Current analytical methods that provide quantitative measures of individual PFAS in AFFFs, such as liquid chromatography – tandem mass spectrometry (LC-MS/MS), are often complicated, time-consuming, and expensive. Methods for total fluorine analysis, though quantitative,...
