The purpose of this study was to test, by means of
a controlled classroom experiment, the effectiveness of
an experimental method involving the introduction of
regular dictation of unpracticed material beginning with
Lesson 25 in the Gregg Shorthand Manual Simplified,
Second Edition, by Gregg, Leslie, and Zoubek.

In an attempt to understand the phase equilibria and petrogenesis of MORB anorthitic plagioclase, Cr-spinel commonly hosted within anorthitic plagioclase has been investigated petrographically and compositionally. Based on spinel-anorthite relationships from three samples of plagioclase ultra-phyric basalt (PUB; Southeast Indian Ridge, Axial Seamount and West Valley Segment, Juan de Fuca...
Highlights: New data reveal for the first time a history of the last ∼33.7 ky of uplift of Samosir. Minimum uplift rates were high (4.9 cm/year) for the first 11.2 ky but diminished after that to <1 cm/year for the last 22.5 ky. Numerical modeling suggests that rebound of remnant...

In grasslands, grazing by large ungulates can influence vegetation structure, composition, primary productivity, and ultimately, ecosystem functioning. While grazing represents a complex disturbance, grazing intensity largely determines the effects of
grazing on vegetation. Structural and compositional changes in the plant community caused by grazing could have bottom-up effects on species...

The purpose of this study was to analyze and describe
the opinions and characteristics of black students enrolled
in Portland Community College.
Data were obtained through a random sampling of two
groups of subjects who were invited to participate in the
study as follows: (1) Black subjects were 109 students...
This study examines the spatial characteristics
of the seafood processing industry on the Oregon Coast.
Three study areas are discussed: the Astoria area, the Newport
area, and the Coos Bay area. The industry is categorized
by four types of seafood processors. Types and
uses of processing and nonprocessing space are...
