This thesis is the combination of two research publications working toward a unified strategy in which to represent complex engineered systems as complex networks. Current engineered system modeling techniques segment large complex models into multiple groups to be simulated independently. These methods restrict the evaluations of such complex systems as...
Methane derived authigenic carbonate (MDAC) precipitation occurs within marine sediments as a byproduct of the microbial anaerobic oxidation of methane (AOM). While these carbonates form in chemical and isotopic equilibrium with the fluids from which they precipitate, burial diagenesis and recrystallization can overprint these signals. Plane polarized light (PPL) and...
This thesis focuses on the investigation of extraterrestrial tracers Ir, Pt and 3He in polar ice cores. These tracers may be used to identify characteristics of interplanetary dust particles, and to quantify the flux of extraterrestrial material during impact events, certain volcanic eruptions, and stable background periods. In the first...
Resilience is a key driver in the design of systems that must operate in an uncertain operating environment, and is a key metric to assess the capacity for systems to perform within the specified performance envelop despite disturbances to their operating environment. This paper describes a graph spectral approach to...
The purpose of this study was to explore and describe how the orientations and knowledge of linguistically responsive teaching, as well as personal characteristics of school-based agriculture education (SBAE) teachers, influence the frequency of their implementation of linguistically responsive practices. Grounded in the Linguistically Responsive Teaching framework by Lucas and...
Oregon State laboratories are responsible for a significant portion of the university’s overall resource and energy consumption, and therefore minimizing waste in a sustainable way should be a top priority for the university while aiming for carbon neutrality by 2025. This study addresses major factors that should be considered when...
Textiles (including basketry, cordage, woven, knotted, or plaited products) make up a considerable portion of the perishable archaeological record in dry caves of the northern Great Basin region, much of which is created from plants and plant fibers. The archaeological study of precontact textiles greatly informs our understanding of how...
River impoundment by dams, along with other human driven changes, has threatened the health of riparian forests in the northern Great Plains for much of the last century. Two major concerns in the region are the impediment of natural recruitment of plains cottonwood (Populus deltoides Marsh. subsp. monilifera (Ait.) Eckenw.)...
Outdoor adventure education (OAE) has long held on to the assumption that learning is transferred to participants’ lives (e.g., Gass, 1985). Recent scholars have contested this assumption, noting that learning transfer may not be a complete lens through which learning is viewed. Transformative learning theory (e.g., Mezirow, 1991) has been...
