Pendent Usnea species were collected in western Oregon and examined.
Character states, such as cortex-medulla-axis ratio; fibril length; papilla diameter;
branching patterns; and presence or absence of fibrils, papillae, soredia, isidia; plus
chemistry, were recorded and analyzed by inspection for differences. Historical
names were researched in the literature. A comparison...
The primary goal of my studies was to elucidate the mechanisms for the well-recognized interaction between two nutrients, vitamins E and K. The outcomes from my studies assess mechanisms for adverse effects of vitamin E and provide novel information on mechanisms for vitamin K homeostasis. These findings will provide information...
The major nutrient requirements of the blue-green alga Anabaena
spiroides Klebahn were investigated. It was hoped that the results would allow the development of a balanced culture medium in
which the alga would exhibit rapid growth and retain typical morphological characteristics.
The alga was isolated from Upper Klamath Lake, Oregon,...
The purpose of this study was to learn about the experiences of Generation 1.5 Hispanics in developmental English in community college. A qualitative comparative case study design was used for this social critical study. The key findings fell into three categories: road blocks, motivators, and actions. The road blocks included:...
Historically, rural economic development has focused on attracting outside firms or increasing exploitation of natural resources, often without equitable or lasting returns to the community. The Rural Wealth Creation framework was developed as a systems-based approach to assessing and leveraging local assets for the creation of lasting wealth in communities....
We believe concreteness, direct manipulation and responsiveness in a visual programming language increase its usefulness. However, these characteristics present a challenge in generalizing programs for reuse, especially when concrete examples are used as one way of achieving concreteness. In this thesis, we present a technique to solve this problem by...
The relationship between intrinsic fish quality (fish condition before handling), production efficiency, product price, and the optimal management of commercial "wild" fisheries was explored in four companion papers. The optimal management plan-consisting of quotas and harvest schedules - would maximize the discounted net industry revenues (NPV) given a minimum biomass...
Every year in the late summer, patches of the Columbia River estuary begin to turn red. These patches are blooms of mixotrophic ciliates (Myrionecta rubra or Mesodinium rubrum/major) (MR) that ingest the chloroplast of their prey, the cryptophytes (CR) Teleaulax amphioxeia (Peterson et al., 2013), and use the acquired organs...
Research studies indicated that differences in cognitive
processing style influence individual behavior on various types of
tasks. This study investigated the effect of the cognitive style
dimension, field independence-dependence, on the metacognitive
functioning of individuals involved in three problem tasks which
varied in inherent structure.
Twenty-six subjects were randomly selected...
