How do we bridge the mismatch between teachers and students based on race and ethnicity currently in our nation's schools? The teaching force remains overwhelmingly White, while the percentage of K-12 students of color continues to rise. Because of cultural dissonance, teachers may not understand the needs of their students....
The collective chemosensing of nonexcitable mammalian cells involves a biochemical network that features gap junction communications and heterogeneous single cell activities. To understand the integrated multicellular chemosensing, we study the calcium dynamics of micropatterned fibroblast cell colonies in response to adenosine triphosphate (ATP) stimulation. We find that the cross-correlation function...

Site ORYA3, the Smith House, is located in Dayton, Oregon. The archaeological project originated because owners of this structure, listed on the National Register of Historic Places, applied for a demolition permit. The 1859 home, first occupied by two early Oregon pioneers, Andrew and Sarah Smith, was considered architecturally significant,...
The portion of the Oregon coast extending from Cape Blanco south into California has long been recognized as a distinct physiographic region, with probable ramifications for prehistoric subsistence and settlement patterns. Several researchers have proposed models outlining a greater reliance upon marine/littoral resources among groups within this region, while more...
Welcome to the 4-H Sheep Project. You are joining an industry that returns millions of dollars to farmers each year, and caring for one of the oldest domesticated farm animals. Wool has been used for clothing since the days of the earlier settlers, and flocks of sheep have supplied both...
An analog simulation of the postural control system (PCS) of a
dog is used to illustrate how modern systems simulation can be applied
to a study of complex life systems. Even though many bold
assumptions were required to adequately simplify the PCS model, the
simulation provided intuitive insight and gave...
This work has the purpose of presenting an approach to attitude
control applicable for sun alignment on scientific payloads.

error signals, four solar cells are disposed about the body of
the payload. As a secondary source a pair...
Most technological problems associated with man-machine conversations
have been solved and are well documented in both the
contemporary technical and lay literature. The major remaining
technological problem is the real time conversion of a human's vocal
uterances into a "written" phoneme sequence representing the information
content of speech. The work...
A static analysis of quadruped biomechanics, combined with
observations of longitudinal postural movement, has revealed important functional attributes of the postural control system. Since
posture is an outward expression of central nervous system (CNS)
behavior, these results may contribute to an understanding of integrative
functions of the CNS.
Beginning from...
Students will develop and apply reading, language arts, and science processes to analyze comics, and demonstrate writing skills in creating their own comic about a local invasive species.
Hypersensitive response-like (HR-like) needle reactions to infection by the white pine blister rust pathogen, Cronartium ribicola, have been reported for several species of five needle pines native to western North America. The best-studied examples are in Pinus monticola and P. lambertiana. In these species a "needle spot" phenotype has been...

One method of estimating the longwave radiative heating of the atmosphere is to combine satellite observations of emitted radiances with those computed from synoptic temperature and humidity profiles. Modeled and observed radiances are brought into agreement by altering cloud properties or even by adjusting the temperature and water vapor profiles....
Task persistence has been associated with task mastery in many different realms of learning, and is thought to be evoked particularly through the observation of positive models; however, the capability of such exposures to transfer across domains is not currently well-understood. The present study sought to examine the effect of...
The primary purpose of this study was to determine whether
there were significant differences between Oregon community
college collegiate freshmen and Oregon State University freshmen in
terms of interest, values, and manifest needs.
The study was limited to a representative sample of the freshman
population in the lower-division collegiate program...
Throughout society, many believe women are not succeeding professionally because of the institutional barriers created by men in the American workforce. However, women may be more competitive with other women than with men, especially when limited job positions are the goal. Competitiveness among women can be explained by a phenomenon...
The Caliciviridae contains many viruses which are pathogenic to humans, marine
