Commercially collected Douglas-fir seed from a moist coastal
ecotype (LaPush, Washington) and a dry inland ecotype (Kaibab
National Forest, Arizona) were subjected to osmotic stresses ranging
from 0 to -8 atmospheres using Carbowax polyethylene glycol 6000
during imbibition and germination. To determine the effect of osmotic
stress on the initiation...
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...
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...
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;...
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...
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...
As childhood obesity rises in the United States, so does the need for effective, sustainable physical activity interventions. The purpose of this study was to assess the feasibility of an early morning care program as well as determine the program’s effects on moderate-to-vigorous physical activity (MVPA) during the program and...
Family Child Care Homes (FCCHs) are the second largest provider of non-relative care in the U.S. However, despite providing care for nearly 1.9 million children under the age of 5, little is known about the physical activity levels of children attending FCCHs. This dissertation sought to provide new information with...
In order to investigate potential climate impacts on landscape-scale ecosystem processes, I implemented a dynamic general vegetation model (DGVM) over a large domain in northern California and western Nevada on a rectangular grid of ca. 800-meter spatial resolution. I used 100 years of observed, monthly climate and nine future climate...
