Annual bluegrass (Poa annua L.) is a prolific annual grassy weed that can be found worldwide in most landscapes. Known for its ability to produce seedhead at low heights (0.32 cm), thrive in over-maintained areas, and germinate anywhere, annual bluegrass is a highly invasive weed. Due to annual bluegrass’ persistence,...

Cinder cones are useful geomorphic features for geological analysis because they generally have known initial states and follow a similar pattern of degradation as they are exposed to erosive processes. This is largely because cinder cones are produced by monogenetic eruptions. Characterizing large cinder cone fields in terms of age...
The quality of wine is highly influenced by the weather.
Temperature, solar radiation and humidity influence the
formation and concentration of aroma-active compounds and
aroma-active precursors in the grapes. Pinot noir grapes require
a slow ripening, under cool temperatures, in order to achieve
their fullest flavor. The main objective of...
This thesis details my investigation of some pharmaceuticals and natural products on the transport of drugs which are substrates of P-glycoprotein (P-gp), such as cyclosporin A (CSA) and digoxin by using Caco-2 and MDCKII-MDR1 drug transport models. Three objectives were performed to address this goal. The first objective was to...
This dissertation combines volcanological research of three convergent continental margins. Chapters
1 and 5 are general introductions and conclusions, respectively. Chapter 2 examines the spatiotemporal
development of the Altiplano-Puna volcanic complex in the Lípez region of southwest Bolivia, a locus of a
major Neogene ignimbrite flare- up, yet the least...
Breast cancer is the leading cancer in women with an estimated 13% of women in the United States developing a form of invasive breast cancer in her lifetime. The survival rate is estimated to be 85%, but the American Cancer Society estimates that early detection of breast cancer in the...
The purpose of this study is to develop an analytical framework for identifying and evaluating conditions that precipitate currency devaluation like those experienced by Mexico in 1994. This study develops a framework of financial and macroenvironmental indicators that point to potential currency devaluation in the future. Some of these indicators...
For twenty-two years, I observed trees and shrubs planted for windbreaks in eastern Oregon. In this paper some conclusions are drawn, although I will be the first to emphasize that the knowledge we need and do not have would fill a much more extensive report. My observations and field work...
Early learning skills, such as executive function (EF), are a key component of healthy development and predict long-term academic success. Yet many children are entering kindergarten without the necessary skills (including EF) that are needed to set them on a successful learning trajectory. Early prekindergarten classrooms that encourage a high...
Tourism is one of the largest industries in the world, and causes many cultural, environmental, and economic problems. In this thesis, I explore ethics in the field of tourism studies, and identify three ethical models used to discuss ethics in tourism, which are: business ethics, alternative tourism, and philosophical ethics....
