In this study I discuss the state of Free-Choice Learning research, and an investigation into the use of personal ubiquitous technology on visitors' experiences at a science center. The three manuscripts included in this document:
1. Review published research on free-choice learning from 1997-2007 from selected journals
2. Examine visitors'...
Due to the overwhelming concern for the current state of our oceans, The Pew Ocean Commission (2003) and the U.S. Commission on Ocean policy (2004), have both strongly recommended an increase in our society’s ocean literacy. An increase in ocean literacy can be achieved through informal education institutions such as...
The Cooperative Institute for Oceanographic Satellite Studies
(CIOSS) partners with The Science and Math Investigative Learning
Experiences (SMILE) Program to bring ocean sciences and satellite
oceanography to high school students and teachers around the
state of Oregon. This study was conducted as a formative program
assessment during the third year...
Eastern filbert blight (EFB), caused by Anisogramma anomala (Peck) E.
Miiller, is a devastating disease to orchards of the European hazelnut (Corylus
avellana L.) in the Willamette Valley, Oregon. Host resistance is the most
desirable means of disease control. Fifty-eight hazelnut accessions, including
European cultivars and interspecific hybrids were evaluated...
The chemolithoautotrophic nitrite oxidizing bacteria (NOB) participate in the
biogeochemical cycling of nitrogen by catalyzing and conserving energy from the
oxidation of nitrite (NO₂-) to nitrate (NO₃-) via a nitrite oxidoreductase (NXR). The
main objective of this work was to comparatively annotate and analyze the genome
sequences of Nitrobacter winogradskyi...
The three dimensional structure of both a ligand and its cognate receptor are required for the success of structure-assisted drug design. This thesis reports the crystal structure of hectochlorin, a small, bioactive molecule, and the steps toward determining the crystal structure of an RNA molecule that is an attractive target...
Given the current state of our oceans, the Pew Oceans Commission (1993) has strongly recommended that increased efforts be made towards ocean literacy. Informal education and outreach programs like the Whale Watching Spoken Here program are important contributors to life-long learning. However, there is little research looking at how these...
Twenty-one pairs of simple sequence repeat (SSR) primers were used to
investigate genetic diversity in 270 accessions of European hazelnut (Corylus avellana)
representing a wide geographic range. A capillary electrophoresis system and ABI
Genescan® and Genotyper® software were used to determine the allele size generated
from each PCR reaction based...
New highly polymorphic simple sequence repeat (SSR) markers for European hazelnut (Corylus avellana L.). were developed from several sources. The markers were characterized, and segregation in a mapping population allowed to assign them to linkage groups. Their transferability across genera and species in the Betulaceae family was investigated. SSR markers...
The hundred-year history of the hazelnut industry in the Pacific Northwest is threatened by eastern filbert blight (EFB) caused by the fungus Anisogramma anomala (Peck) E. Müller. Marker-assisted selection (MAS) has been extensively used for ‘Gasaway’ resistance in the hazelnut breeding program at Oregon State University. Concern over breakdown of...
