This qualitative study examined the experience of White student affairs professionals involved in racial justice work at a predominantly White institution in the Pacific Northwest. This study explored participants' consciousness of their white identity, white privilege, and commitment to end systems of privilege and oppression in regards to White supremacy...
This project aimed to address the topic of children with disabilities through a well-researched children’s book. Dancing with my friend Maddie is a children’s book that focuses on a friendship between Claire, a typically developing first grader, and Maddie, a first grader with Down syndrome. Research has shown that addressing...
Students struggle with the concept of functions and the notation associated with it in various mathematical contexts. This thesis investigates student understanding of function notation through their generalization of single variable functions to multivariable functions in a variety of situations. Semi-structured student interviews were conducted and analyzed through a framework...
An economic survey of the commercial operators currently active in the Queensland Reef Line fishery has been carried out, as part of a research project aimed at evaluating options available to manage the fishery. We present the background analysis of the fishery used as a basis to develop the sampling...
In RNA-directed silencing pathways, ternary complexes result from small RNA-guided ARGONAUTE (AGO) associating with target transcripts. Target transcripts are often silenced through direct cleavage (slicing), destabilization through slicer-independent turnover mechanisms, and translational repression. Here, wild-type and active-site defective forms of several Arabidopsis thaliana AGO proteins involved in posttranscriptional silencing were...
Laser-based spectroscopic techniques, such as cavity ring-down spectroscopy (CRDS), provide a new, cost effective and more widely available approach to measure the oxygen isotope ratio in water molecules, H₂¹⁸O/H₂¹⁶O (δ¹⁸O), and are used increasingly to measure δ¹⁸O in the world's oceans. Here, we present results from an interlaboratory comparison designed...
In eukaryotes, RNA silencing pathways utilize 20-30-nucleotide small RNAs to regulate gene expression, specify and maintain chromatin structure, and repress viruses and mobile genetic elements. RNA silencing was likely present in the common ancestor of modern eukaryotes, but most research has focused on plant and animal RNA silencing systems. Phytophthora...
From July, 1982 to August, 1983 I had the privilege of serving an internship
as an oceanographer at the National Marine Fisheries Service Beaufort
Laboratory. During the period of my appointment I assisted in a preliminary
assessment of the potential fishery impacts of ocean thermal energy conversion
(OTEC) power plants....
It is desirable for complex engineered systems to perform missions efficiently and economically, even when these missions' complex, variable, long-term operational profiles make it likely for hazards to arise. It is thus important to design these systems to be resilient so that they will actively prevent and recover from hazards...
Mycobacterium avium cause disseminated disease in immunocompromised people such as AIDS patients. Subsequent to crossing the intestinal epithelium, M. avium thrive within vacuoles in macrophages. The bacteria exhibit a different, more invasive, phenotype after being in macrophages compared to M. avium from laboratory conditions. We hypothesized that this intracellular phenotype...
