This was an experimental study designed to compare the effectiveness
of computer-assisted laboratory instruction to teacher-assisted
laboratory instruction based on student achievement in Elementary
Business Statistics. Computer-assisted laboratory materials and an
Elementary Business Statistics achievement test were evaluated.
Procedures
The setting of this experiment was at Southern Oregon State
College,...
Few studies analyze the relationship between ecological knowledge and public preferences for natural resource management options. The Central Cascades Adaptive Management Area (CCAMA) and McKenzie watershed of western Oregon provides an opportunity to examine the relationship. This research project employs a mixed model approach to explore public knowledge of forest...
Pyrolysis of 4-cycloheptene-l-methyl acetate under flow conditions at 285° gives only rearranged bicyclic acetates and hydrocarbons rather than the anticipated simple elimination product methylenecyclohept- 4-ene. These rearranged acetates have the same structures and are formed in virtually the same relative percentages as those observed in the "π- route" solvolysis of...
This study was undertaken as a result of an interest in the
present and future purposes and functions of higher education.
American society and higher education are moving through a period
of change. Since each shapes and is shaped by the other, change in
either may require a review and...
Recent research shows that flower parts of strawberry (Fragaria X ananassa Duch.) differ in their capacity to support the growth of Botrytis cinerea, the fungus which causes gray mold on fruit. Growth in styles is slow and hyphae rarely enter the carpel (achene), suggesting that this pathway is not the...
Biotic and abiotic processes at continent-ocean interfaces cycle a disproportionate mass of carbon and nutrients relative to their global surface area, and microbial activity is a principal determinant of organic and inorganic matter flux in these transition zones. Most studies using modern high-throughput ‘omics techniques to link microorganisms with costal...
Quaternary Ammonium Compounds, Qams, are an important class of
chemicals which present interesting challenges to analysts. This thesis
reports results of investigations on uses of ion-pairing techniques for
separations and detection of Qams. Special apparatus for post-column
solvent extraction of liquid chromatographic eluates was developed as
part of this work....
