Spatial Variability Mapping of pH in Oregon Organic Farms using Geographic Information Systems (GIS) Geospatial Interpolation Models

Creator:: Stewart, Julie A.
Abstract:: This internship project (Dr. Dawn Wright—Department of Geoscience) was a synthesis of several aspects of the research process. The documentation of methods consisted of: primary data collection of soil samples, geographical coordinates, georeferencing, basemap creation, laboratory machine operation, laboratory methods, laboratory quality control planning, statistical analysis, and geo-statistical analysis using...

The infrared spectrum of the nitrate ion in various crystalline environments

Creator:: Stewart, Julie Lingscheid
Abstract:: The infrared absorption spectra in the out-of-plane bending (v₂) region of potassium nitrate were studied for three phases. Several types of sampled were used: nujol mulls, fused samples, and N¹⁴-N¹⁵ isotopic mixtures. The existence of three of the reported polymorphic phases was confirmed by the spectra. The transitions between phase...

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...

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...

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;...

Artificial Swarm Control Through Learning Based Leadership

Creator:: Tuzel, Ovunc
Abstract:: Collective migration in animal groups is often guided by distributed leader agents that influence their peers by modulating their motion behaviors. Distributed leadership is a promising navigation strategy for artificial swarms, but designing the leaders’ controllers is difficult due to the swarm’s collective emergent behaviors. The presented research formulates a...

Understanding Molybdenum Isotope Dynamics in Terrestrial Environments

Creator:: King, Elizabeth K.
Abstract:: This dissertation works towards determining the mechanisms driving the Mo isotopic composition of soils, and how these signals may be used to refine the use of Mo as a proxy of biogeochemical processes. The first step towards quantifying Mo fractionation in soils is to determine the mechanisms controlling Mo accumulation,...

Exploring the System-Based Influences on Professional Goals of Early Career Agriculture Teachers in California: A Phenomenological Approach

Creator:: Ermis, Grant L.
Abstract:: Agriculture teachers, in comparison to other high school teachers, work in more varied and demanding work environments (Terry & Briers, 2010; Torres, Ulmer, & Aschenbrener, 2008). The body of literature studying the impacts of more varied and demanding work environment on early career agriculture teachers (ECATs) is commonly limited to...

An Evaluation of Onboarding and Training Procedures of Oregon State University County Extension Faculty

Creator:: Knight, Kelsey J.
Abstract:: Oregon State University Extension employs county-based Extension Faculty to deliver educational programs to communities across the state. County Extension Faculty are expected to be competent in various content and training can help prepare faculty for the profession. Using a needs assessment approach, this research evaluated the training available. The results...

Interactions between nitrogen, phosphorus, and molybdenum in forest soils and cyanobacterial lichen in the Oregon Coast Range

Creator:: Marks, Jade A.
Abstract:: 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....
