This research studied the role of shared ownership on virtual team effectiveness, using student teams enrolled in engineering management coursework at Oregon State University and Virginia Polytechnic Institute. After a thorough review of the literature, the concept of shared ownership was developed. This concept was operationalized as the extent to...
An actuated, bipedal model is developed to investigate lateral plane locomotion dynamics and stability on inclines. Both the point mass case and rigid body case are considered. Variations in the force-free leg length are determined via inverse dynamics to explicitly and implicitly match prescribed lateral and fore-aft force profiles, respectively....
The Pacific red lionfish has recently invaded Western Atlantic and Caribbean coral reefs, and may become one of the most ecologically harmful marine fish introductions to date. Lionfish possess a broad suite of traits that makes them particularly successful invaders and strong negative interactors with native fauna, including defensive venomous...
Predatory lionfishes (Pterois volitans and P. miles) were introduced to Florida waters during the mid to late 1980s, and eventually established self-sustaining breeding populations in the tropical western Atlantic. These invasive species are now widespread along the southeastern seaboard of the United States, across the Caribbean Sea, and in the...

Predatory lionfishes (Pterois volitans and P. miles) were introduced to Florida waters during the mid to late 1980s, and eventually established self-sustaining breeding populations in the tropical western Atlantic. These invasive species are now widespread along the southeastern seaboard of the United States, across the Caribbean Sea, and in the...
Red tree voles (Arborimus longicaudus) are a unique species of Arvicoline rodent found in western Oregon and northwest California. Their preferred habitat is mature and old-growth coniferous forest dominated by Douglas-fir (Pseudotsuga menziesii). Tree voles are an important prey item for northern spotted owls and many other predators, but are...
Nisin, a bactericidal polypeptide, has the potential to inhibit spoilage bacteria and control rnatolactic fermentation in wines. Nisin activity has previously been observed to remain stable in white wines but to decrease in red wines. This decrease is believed to be directly proportional to the concentration of polyphenolic compounds in...
The purpose of this thesis is to explore civil engineering students’ and professional civil engineers' understanding of concepts within statics and fluid mechanics. The studies described herein begin to examine theories of situated cognition utilizing concept inventories, which are sets of multiple-choice questions where the incorrect answers are based on...
Molybdenum is an essential component of biogeochemical cycling, most notably as a component of the nitrogenase enzyme used in biological nitrogen (N) fixation. While the important role of phosphorus (P) in limiting N fixation in ecosystems has been well documented, occurrence and prevalence of molybdenum (Mo) limitation is largely unknown....
