Groundwater is a vital resource and efforts must be made to protect its quality. In certain areas, its quality has been
threatened by the introduction of oil and gasoline, many times originating from underground storage tanks. Massachusetts has
directly reacted to this concern about groundwater quality by promulating a Massachusetts...
This research applies the biologically inspired, artificial evolutionary processes of Genetic Algorithms and Genetic Programming to digital hardware circuit synthesis and minimization. In this new application, three approaches are taken to genetic hardware development. First, as a method for logic synthesis, Genetic Programming is applied to the building of logic...
Ageism in the context of global population aging could lead to increasing human and economic costs. Age stereotypes tend to be negative (Hummert, 1990) and ubiquitous (Nelson, 2002) there are a variety of well documented detrimental consequences of negative age stereotypes on older adults' physical, cognitive and psychological outcomes (Hummert,...
In a steady state, the Earth's absorbed solar radiation (ASR) balances the outgoing
longwave radiation (OLR) at the top of the atmosphere (TOA). In response to a radiative
forcing, that is, an external perturbation to the top of the atmosphere energy balance, the
Earth's climate system adjusts until reaching a...
The black and white pattern formed when an individual word is
printed on a page was analyzed by the Fourier transform. The Fourier
transform produces a sequence of sinusodial functions, usually called
spatial frequencies, whose amplitudes depend upon the particular
pattern analyzed. These amplitudes were examined to determine if the...
The European hazelnut, Corylus avellana L., was imported into the U.S. in the late 1800's and is now grown throughout the Willamette Valley in Oregon. A native species of hazelnut, C. cornuta Marshall, is a common shrub found in forested areas of the Pacific Northwest. Foliage of both C. avellana...
As indicated by the title The Collision of Quadratic Fields, Binary Quadratic Forms, and Modular Forms, this paper leads us to an understanding of the relationship between these three areas of study. In [4], Zagier gives the results of an intriguing example of the relationship between these areas. However there...
This research addressed the complexities of identity development in the lives of seven elementary and middle school preservice literacy teachers during their graduate teacher education program at a private western university using a poststructural feminism theoretical lens. This research investigated two questions: 1) How do preservice teachers develop their identity...

The focus of this autoethnography was an in-depth analysis of the recorded experiences of a middle school math teacher's transitional development from classroom teacher, to teacher leader. The following research questions guided this study: (1) In what ways did the researcher’s view of self as a teacher leader change during...
Radiative feedbacks associated with changes in water vapor, temperature, surface albedo and clouds remain a major source of uncertainty in our understanding of climate's response to anthropogenic forcing. In this dissertation climate model data is used to investigate variations in feedbacks that result from changing CO₂ forcing and the time...
The purpose of this qualitative study was to examine the experience of white principals in understanding their white identity, privilege, and power as they worked to implement socially-just and culturally proficient schools. The findings offer insights into the following questions: 1) How do white school leaders view white identity and...
The purpose of this case study was to examine a third-grade teacher’s effective use of mathematical discourse in the classroom setting. The study offers insights into the following research questions: 1) How does a teacher’s engagement in mathematical discourse communities influence her practice and self-efficacy as a mathematics educator? 2)...
Instructional time for social studies in elementary classrooms has decreased
since the passage of Goals 2000 and No Child Left Behind, with content contracted to align with reading goals. Consequently, opportunities for preservice teachers to observe and teach social studies lessons have diminished. This qualitative multiple case study examines the...
This autoethnography explores issues that impact educational leadership by examining individual reflections, perceptions, and responses developed through the lens of a principal of two elementary schools. The main data source involves journal entries collected over a period of one year. Theories of educational leadership styles and effective school practices form...
The National Council of Teachers of Mathematics published their vision of active, problem-centered instruction with a goal of conceptual understanding in 1989. Fifteen years after these reforms were proposed the changes are reflected in school policy and elementary mathematics curriculum, but only limited change has actually occurred in classroom instruction....
The purpose of this qualitative case study was to investigate the development of social norms in a fifth-grade reform-based mathematics classroom through a close examination of one teacher's actions during the first three weeks of school. This study offers insights into the following research questions: 1) How does an elementary...
Enzymes play an important role in the environment, they breakdown natural-occurring and anthropogenic molecules so that they can be transported into cells and utilized. Enzyme assays are routinely used in soil science and oceanography to measure the activities of specific processes and to serve as general indicators of microbial activity....
Climate sensitivity is generally studied using two types of models. Atmosphere-ocean general circulation models (AOGCMs) include interactive ocean dynamics and detailed heat uptake. Atmospheric GCMs (AGCMs) with slab ocean models (SOMs) cannot fully simulate the ocean's response to and influence on climate. However, AGCMs are computationally cheaper and thus are...

This study explores the lived experiences of first-year, rural, Oregon students in their initial entry to college. Through qualitative research involving one-on-one interviews with 10 participants, the author examines the transition of rural students into higher education, common experiences of rural students in their first term of college, and perceived...
Chemoreception is one of the dominant sensory modalities for many species of salamanders (reviewed in Chapter 2). At least seven of the ten currently recognized salamander families are known to respond to some sort of chemical cue. These responses are as varied as delaying hatching, seeking refuge, or initiating aggressive...
