Characterization of hydrologic parameters and processes in shrink-swell clay soils

Creator:: Stewart, Ryan D.
Abstract:: Vertisols and other vertic-intergrade soils are found all over the globe, including many agricultural and urban areas. These soils are characterized by their cyclical shrinking and swelling behaviors, where bulk density and porosity distribution both vary as functions of time and/or soil moisture. In turn, alterations in physical soil parameters...

Infiltration and temperature characterization of a wastewater hyporheic discharge system

Creator:: Stewart, Ryan D.
Abstract:: The Clean Water Act imposes Total Maximum Daily Load (TMDL) limits on pollutant concentrations within wastewater effluent; in Oregon, thermal discharge is one of the pollutants subject to regulation. The City of Woodburn, Oregon, funded a series of pilot scale studies to investigate the utility of natural systems to reduce...

A General Purpose Agent-Based Blackboard Optimization Method Applied to Sodium Fast Reactor Design and Analysis

Creator:: Stewart, Ryan H.
Abstract:: We present a novel multi-objective optimization methodology built upon a multi-agent blackboard framework. This multi-agent blackboard system (MABS) synthesizes blackboard architectures, multi-agent environments, and optimization theory. The blackboard architecture creates the framework for initializing, storing, and solving a multi-objective optimization problem. Multiple agents allow for an optimization problem to be...

That’s Not in My Position Description: A Discourse Analysis Study of SBAE Teacher Migratory Context

Creator:: Haddad, Becky
Abstract:: The purpose of this study was to unfold positions of migrating SBAE teachers to understand support and challenge to retain teachers in migratory contexts. Previous literature discusses problems related to teacher mobility as functions of teacher-student matching, teacher skill and effort, school environments, and advancing student learning. In an effort...

In-plane Creep Behavior of Cross-laminated Timber and Mass Plywood Panels: A Methodology to Evaluate the Long-term Performance of Post-Tensioned Mass Timber Walls

Creator:: Longman, Ryan P.
Abstract:: Post-tensioned (PT) self-centering shear walls were designed to reduce structural damage from seismic activity. However, these lateral force resistant systems experience post-tension loss negatively affecting the re-centering capability due to delayed deformations experienced by engineered wood products over time. The long-term mechanical response of mass-timber panels to in-plane PT loads...

Linking phylogenetic identity and biogeochemical function of uncultivated marine microbes with novel mass spectrometry techniques

Creator:: Bryson, Samuel J.
Abstract:: The combined activities of diverse heterotrophic marine microorganisms significantly shape global biogeochemical cycles, but models of these activities are currently limited to aggregate microbial community processes, and it remains unclear how community structure and the functional roles of specific microbial taxa should be integrated into these models. Therefore, understanding the...

Developing Tools to Utilize the Oregon State University Woody Plant Collection and Establish a Campus Arboretum

Creator:: Blanchard, William D.
Abstract:: Oregon State University campus grounds have long been admired for their beauty and the diversity of over 65,000 individual woody plants that grace the 570 acres of campus. The woody plant collection has provided a living learning laboratory for the university and surrounding community for decades. The campus grounds include...

A systematic review and phenomenological analysis of university supervisors’ feedback processes with school based agricultural education teacher candidates through a framework of positive psychology

Creator:: Schmidt, Kirby
Abstract:: University supervisors are critical to improvement in K-12 teaching and learning due to their roles in designing field experiences, managing relationships, mentoring, and supervising teacher candidates. The encouragement, support, and feedback shared by university supervisors in respect to the teaching performance of teacher candidates is especially powerful, and is a...

Exploring How Alternatively Certified Agriculture Teachers Acquire Practices and Participate in a Community of Practice: A Hermeneutic Phenomenology

Creator:: Claflin, Kellie
Abstract:: The purpose of this hermeneutic phenomenological study was to explore the lived experience of alternatively certified agriculture teachers, acquire the practices of agriculture teachers, and participate in the agriculture teacher community of practice. The study was grounded in an interpretivist approach, which provided an alterantive perspective to the positistic-like research...

The effects of a S.M.A.R.T. goal setting and self-monitoring intervention on physical activity and fitness in middle school students

Creator:: McDonald, Samantha M.
Abstract:: A large body of evidence suggests physical activity is inversely associated with several cardio-metabolic risk factors among children and adolescents. Despite these health benefits, a majority of youth are not meeting the physical activity guidelines set forth by the USDHHS. Schools have been identified as an ideal vehicle for interventions;...
