This investigation was designed to determine the effectiveness
of video-tape feedback as a technique to modify some selected behaviors
of untrained prospective elementary teachers. Four verbal
and four nonverbal behaviors were considered; they were: teacher
questioning, teacher telling, teacher distractive verbal, teacher
allowing for pupil verbal, teacher constructive nonverbal, teacher...
The distributions of alkaline phosphatase, acid phosphatase,
non-specific esterases, and glycogen were described for the antennal
glands of the freshwater crayfish, Pacifastacus, and the marine crabs
Cancer and Pugettia.
Alkaline phosphatase is confined primarily to the luminal edge
of the labyrinth in all of the above forms whereas acid phosphatase...
This paper explores predictors of support for land-use ballot initiatives in Oregon. Possible predictors include a variety of socioeconomic, spatial, and political variables. Multiple least squares regressions find that aggregate levels of education within a county and the proportion of a county's workforce engaged in farming or forestry occupations appear...
Armillariella mellea (Vahl. ex Fr. ) Karst. was grown aseptically
in hazel stems (Corylus cornuta var. californica) which were used in
the forest to infect 290 ponderosa pines (Pinus ponderosa Laws.)
which had been "stressed" in five different manners plus two control
groups. All trees were inoculated twice giving a...
The use of the exponential-transfer-characteristics of a transistor
junction as a means of giving a logarithmic sweep calibration to a
sampling oscilloscope is presented. The prior work in logarithmic
converters leading up to the use of the transistor's transfer properties
is explored. A circuit adapting a sampling oscilloscope to a...
