Halogenated organic compounds have had widespread and massive applications in industry, agriculture, and private households, for example, as degreasing solvents, flame retardants and in polymer production. They are released to the environment through both anthropogenic and natural sources. The most common chlorinated solvents present as contaminants include tetrachloroethene (PCE, perchloroethene)...
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...
In small forested streams, changes in age and structure of riparian vegetation covering the stream have been shown to directly influence the amount of light reaching the stream benthos. Light has the potential to impact in-stream resources that support secondary production through constraints on primary productivity. The influence of landscape...
This descriptive research project is a survey and analysis of nineteen community mediation programs in the State of Oregon. These programs were evaluated to determine their responsiveness to issues of culture and ethnicity. Data was gathered by face-to-face and telephone interviews with community program staff members and administrators. Information was...
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...
We sought to improve net ecosystem exchange (NEE) estimates for a tall, dense, mature Douglas-Fir forest in the Oregon Coast range characterized by weak flows, systematic wind directional shear, and limited turbulent mixing throughout the diurnal period. We used eddy covariance (EC) observations at two levels and concurrent biological measurements...
The purpose of this study was to explore the connections between experiential learning and pedagogical content knowledge (PCK) in preservice agriculture teachers. More specifically, utilizing a conceptual model for teacher development as a framework, this research sought to explore the development of the knowledge bases needed for teaching through experiential...
Degradation of watersheds is a major concern in areas where adverse climate effects and unsustainable use of the natural resources have caused extensive stresses to watershed systems (e.g., increased floods, increased droughts, worsened in-stream water quality) through the years. While considerable efforts are being made to generate technical solutions that...
Drawing on Deborah Brandt’s “literacy sponsorship,” this thesis examines ways English language learners (ELLs) in the Corvallis Multicultural Literacy Center (CMLC) act as literacy sponsors, sharing their expertise in language, textiles, and cooking, based on nine in-depth interviews with ELLs at the center. The findings of this thesis are presented...
