The specific habitat requirements of harlequin ducks (Histrionicus histrionicus
Linnaeus 1758), which breed in the Pacific Northwest, are largely unknown. I captured
and attached radio transmitters to 42 female harlequins (36 paired and 6 unpaired) in the
central Cascade Range of Oregon in 1994 and 1995. Breeding pairs used 3rd...
Coarse woody debris (CWD, comprised of snags and downed logs) is an important component of the structure and function of forest ecosystems, one which both influences the availability of fuel for wildfires and can be a result of wildfires. We studied snag persistence, and changes in mass of CWD in...
At global and regional scales, tree mortality rates are positively correlated with forest net primary productivity (NPP). Yet causes of the correlation are unknown, in spite of potentially profound implications for our understanding of environmental controls of forest structure and dynamics and, more generally, our understanding of broad-scale environmental controls...
The purpose of this study was to analyze the effect of the use
of vocationally - oriented applications on the achievement and attitude
of community college beginning algebra students. The applications
were chosen to be representative of problems encountered in
a variety of occupations. They were in contrast to the...
The hypotheses of this study stated the following:
Interaction with the computer game will significantly
increase the class means in: (1) mathematical
achievement, (2) attitudes toward mathematics, and (3)
graphing ability in high school advanced algebra.
ALGEBRA ARCADE is a computerized simulation game
played on a coordinate grid. One can...
Two mathematical computer games, POE and EQUATIONS, were used to
test the effects of games as learning aids in a university entry-level
intermediate algebra course. Specifically, this study investigated
whether use of these games would significantly increase student achievement
in the course and improve student attitude toward mathematics.
EQUATIONS is...
The purpose of this study has been to investigate the effects of
an activity approach to teaching geometry in certain high schools of
Afghanistan. A brief review of the historical background of mathematics
education especially in Afghanistan has been presented in this
study. Students in the activity approach were involved...
Purpose of the Study
This investigation was an attempt to determine the relative suitability
of four physical seating arrangements, conventional, crescent,
circular, and non-seating, in terms of their positive attitudinal and
interactional impacts on four senior high school social studies classes
who are enrolled with the same teacher during different...
Senecio jacobaea (tansy ragwort) is a common weed in the
Pacific Northwest that contains toxic pyrrolizidine alkaloids
(PAs). Jacobine, the major PA in Senecio jacobaea, was incubated
with rat liver microsomes and metabolites were isolated by high
performance liquid chromatography (HPLC) and identified by mass
spectrometric analysis. Metabolites included a...
