In 2004, the Transition Mathematics Project (TMP), funded by the state of Washington and The Bill and Melinda Gates Foundation, was established to create projects to help high school students gain the necessary skills to become college and work-ready. Aligned to TMP's College Readiness Mathematics Standards, a fourth-year capstone mathematics...
The purpose of this quantitative study was to identify the combination of factors, both individual and programmatic, that contributed most significantly to the persistence and progression of students enrolled in a public comprehensive community college. As open-access institutions, community colleges cater to students from a broad range of socioeconomic, cultural,...
Tn5 mutagenesis of apdA (for antibiotic production) and deletion of
gacA (for global antibiotic and cyanide) resulted in the same pleiotropic phenotype in
Pseudomonas fluorescens (i.e. production of an array of secondary metabolites
including the antibiotics pyrrolnitrin, pyoluteorin, and 2,4-diacetylphloroglucinol as
well as a tryptophan-side-chain oxidase, hydrogen cyanide, and an...
A major factor in the ability of Pseudomonas fluorescens Pf-5 to act as a biological control agent is its production of antibiotics, including pyoluteorin (PLT), 2,4-diacetylphloroglucinol (2,4-DAPG) and pyrrolnitrin (PRN). The data provided in this thesis demonstrate that the presence of any of these antibiotics in the extracellular milieu affects...
More than half of students in Washington state community colleges enroll in developmental mathematics, but a relatively small percentage of these students persist to the second year. Many students place into these courses and never enroll; others enroll at some point after the first academic term, even when faced with...
Pseudomonas is a diverse genus of Gram-negative bacteria that includes pathogens of plants, insects, and humans as well as environmental strains with no known pathogenicity. Pseudomonas fluorescens itself encompasses a heterologous group of bacteria that are prevalent in soil and on foliar and root surfaces of plants. Some strains of...
Oregon, much like the nation, has historically had a paradoxical relationship to migration. Oregon is famous for the Lewis and Clark expedition and the Oregon Trail. It is, and always has been, greatly affected and inspired by interstate migration yet each successive generation has been less than welcoming to further...
Due to the current cultural paradigm that incorporates the desire to be environmentally friendly and mitigate rising fuel costs, arguments about the cost of public transit systems, ridership rates, and methods to increase use are frequent topics of public policy concern. In response to these cultural and economic concerns, the...
A history of fire suppression, growth in the wildland-urban interface, and changing climate conditions, have created a fire regime in central Oregon that is growing in severity and intensity, putting more people and structures at risk and requiring a greater percentage of state and federal agency budgets to manage fires....
