The three essays in the present dissertation build on and expand the notion of generativity in the context of a learning (i.e., knowledge creating) organization, and learning (i.e., knowledge based) economy in sequential progression with increasing levels of analysis. Essay…

The knowledge of spatial variability soil properties is useful in the rational use of inputs, as in the site specific application of lime and fertilizer. The objective of this work was to map and evaluate the spatial variability of the…

Academics believe in a symbiotic relationship between research and teaching, though evidence challenges its existence. Previous studies may have defined these constructs too narrowly to detect the perceived relationships. This study used a qualitative approach to investigate chemistry professors' beliefs…
