The hemlock woolly adelgid (Hemiptera: Adelgidae: Adelges tsugae; HWA) is an invasive and damaging pest on hemlock in eastern North America. HWA is native to the Pacific Northwest, where it does not damage hemlock. In support of classical biological control of HWA in eastern North America, abundances of native predators...
To investigate the dynamic response of the outer accretionary wedge updip from the patch of greatest slip during the Mw8.8 2010 Maule earthquake, 10 Ocean Bottom Seismometers (OBS) were deployed from May 2012 to March 2013 in a small array with an inter-instrument spacing of ~10 km. Nine instruments were...
I am a woman who writes. I am a writer who is a woman. In the Words
of a Woman is an exploration of how these two facts of my life merge and
influence each other. It is a work written to mediate between the supposed
dichotomies of creative and...
Magnetic and gravity modelling was completed along two E-W transects offshore central Oregon. These models indicate that the backstop-forming western edge of the Siletz terrane has a seaward dip of approximately 40° to 49° at 44°48'N, shallowing to ~28° at 44°1 1 'N. This is a well-determined result, given available...
"This Long Disease, My Life": Alexander Pope and the
Sciences by Marjorie Nicolson and G.S. Rousseau has been the
standard work on Alexander Pope and Newtonian science ever
since it was published in 1968. Literary scholars and
biographers continue to be swayed by its influence.
Unfortunately, the work they so...
A provenance study of crypto-crystalline silicates was performed at the Cooper's Ferry archaeological site in west-central Idaho on the Columbia Plateau. In this research, the author used instrumental neutron activation analysis as well as portable x-ray fluorescence to examine and characterize the geochemistry of 300 geologic samples of crypto-crystalline silicates...
Rising human populations and climate change are putting increasing demands on our already-limited freshwater sources. In response to these concerns, homeowners and municipalities have been encouraged to replace turfgrass – a plant with relatively high irrigation needs – with drought-tolerant plants that do not require frequent irrigation. However, the many...
The perception of a long-term cost advantage of synthetic infill turf systems relative to natural grass systems has contributed to a rise in their popularity in the USA. However, few comprehensive cost assessments of natural grass and synthetic infill systems exist. There are also no studies looking at interactions between...
In this study patterns of shared family time in 210 two-parent,
two-child Oregon households were described. The relationship between
amounts of shared time and a number of family and environmental
characteristics was also researched.
The study used the Oregon data from a contributing project of
the Northeast Regional Research Project...
