Advances in technology such as 3D digital scanning and spatial analysis software have provided archaeologists with novel data. Specifically, these methods increase the researcher's ability to measure artifact morphology and past networks of cultural transmission, to potentially track the movement of past peoples and ideas through space and time. This...
THE PURPOSE OF THE STUDY The major purpose of this study was to determine if there were statistically significant differences among the opinions of teachercoordinators, administrators, and guidance counselors concerning cooperative vocational education. Specifically the objectives were: (1) to determine if there were differences in the opinions of the three...
The differential cross section for the reaction k⁻+p[forward arrow] k⁰+[uppercase xi]⁰ was measured in a spark chamber experiment for an incident k⁻ momentum of 1.8 GeV/c. The target was liquid hydrogen confronted
by an anti-coincidence counter to insure neutral particle production.
A 60 element hodoscope signalled the presence of four...
This study seeks to determine the correlation between changes in statewide land use planning policies and the resulting periods of high or low urban growth in the Willamette Valley, Oregon using automated classification methods and freely available satellite imagery. To protect its farms, forests and open spaces, Oregon became the...
A majority of eighteenth-century novels remain in regular print over two hundred years since their inception. Yet with the possible exception of Robinson Crusoe, they have largely fallen out of popularity, rarely appearing on "The Summer's Hottest Reading" lists or receiving celebrity endorsement. I consider Ian Watt's foundational study, The...
Double-crested cormorants (Phalacrocorax auritus) and Brandt’s cormorants (P. penicillatus) nest sympatrically in a large mixed-species colony on East Sand Island (ESI) in the Columbia River estuary. Ecological theory predicts that such morphologically similar species will partition prey resources when faced with resource limitations. During the summer of 2014, I investigated...
A waveform-preserving, variable time-delay system capable of
several milliseconds delay is described in this thesis. These considerably
long delays are achieved by judicious use of the relatively
low sonic velocity of gases. Initial system design criteria specified
a time delay of ten milliseconds and a signal bandwidth of 0-10 KC....
