This study examined the role perceptions of trustees
in the locally controlled Oregon community college system
and the state controlled Washington community college
system. Authorities in the literature were consulted to
define the "ideal trustee role" and the study determined
which governance system was most effective in fostering
this "ideal...
Sequential machines uniquely determine directed graphs. A path in a sequential machine may be specified by a starting state and an input sequence. A uniform Hamiltonian touring sequence (UHTS) is an input sequence that specifies a Hamiltonian path regardless of the starting state. We present a polynomial time algorithm that...
Forest roads produce fine sediment with traffic during wet weather. If the forest road is connected to a stream it can be a source of turbidity and fine sediment that may be detrimental to aquatic organisms especially salmonids.
The goal of this work was to investigate turbid runoff during wet-weather...
Field observations are made of the formation of backwash ripples
on the beachface, formed by undular hydraulic jumps generated by backwash
down the beach face colliding with wave bores. Measured ripple
wavelengths range from set averages of 48 to 70 cm. Within a particular
set of ripples there is a...
Several experiments were conducted with birds differing in body weight, conformation and sternal measurements to obtain information on whether it would be possible during short term selection to influence the shape of the sternum and, if so, what influence this would have on the amount and distribution of the breast...
Mimicry, obscure colors, and secondary sexual colors were
important classes of observations that were analyzed by nineteenth
century biologists from several vantage points. Adherents of the
doctrine of special creation of fixed species believed animal colors
to be evidence of design; Darwin and Wallace and their successors
suggested that a...
