Vegetation structure is important in structuring avian communities. In the sagebrush biome, where continued habitat loss is thought to threaten shrusteppe-obligate birds, both remotely sensed and field-acquired measures of big sagebrush (Artemisia tridentata) cover have proven valuable in understanding avian abundance. Differences in structure between the exotic annual cheatgrass (Bromus...
Current research on sport motivation has focused primarily on
goal perspective approaches in an attempt to understand behavior in
achievement situations (Ames, 1984; Nicholls, 1984). According to
Nicholls' (1984) theory, the achievement goal orientation an
individual develops may be influenced by both individual differences
and situational factors.
Relative to situational...
The appointment of interim community college presidents, the topic of this study, is a little understood phenomenon. A growing shortage of community college presidents coupled with a lack of replacements suggests the appointment of interims will continue well into the future. This study, with a purpose of looking at the...
The purpose of this study was to determine whether Alexander Astin's
Theory of Student Involvement could be applied to an academic experience in an
overseas setting. Using data collected from the program evaluations of 79 students
who had participated in the Oregon University System exchange program in Lyon,
France during...
The purpose of the study was to learn more about the ways in which caregivers perceive the effects of adult day services. The goal was to help inform adult day providers about services family caregivers find useful. An ecological model was used as a framework. Data were collected from focus...
Today's community colleges are challenged to respond to rapidly changing internal and external environments. Their responses must promote highly responsive and relevant programs and services, while keeping intact the strengths of community colleges--access, student success, and a focus on teaching and learning. Further, these responses must occur in the context...
A greenhouse bioassay was used to compare the effects
of soils collected at different distances from hardwood
species on the growth, mycorrhiza formation, and foliar
nutrient concentrations of Douglas-fir seedlings. Soil
nutrient concentrations and bulk densities were also
determined. Soils were collected from two southwestern
Oregon sites that had been...
Recreational impacts on the subalpine-alpine ecosystems of Mount Rainier National
Park have developed over the past century, and today pose a major problem for park
managers. Field data were collected during the summer of 1987 in the Paradise meadows
area in order to describe visitor impacts on social trails (trails...
