DNA - Uncorking the Bottleneck in Knowledge Elicitation and Organization
There are two main purposes of this paper. First, we describe a novel cognitive tool that was designed to aid in knowledge elicitation and organization for instructional purposes – specifically to be used for intelligent tutoring system development. This automated approach to knowledge elicitation is embodied in a program called DNA (Decompose, Network, Assess). Our aim for this tool is to incr...

متن کاملModeling soil microbial dynamics in carbon and nitrogen cycling
Goal To determine the relative importance of different mechanisms that influence carbon loss from soil under variable soil-moisture conditions. The soil contains more carbon than the atmosphere and plants combined (Scurlock and Hall 1998). This carbon is important for maintaining soil fertility, controlling erosion, and the long-term storage of carbon that could be released into the atmosphere....
متن کاملMicrobial immobilization drives nitrogen cycling differences among plant species
In many terrestrial ecosystems nitrogen (N) limits productivity and plant community composition is influenced by N availability. However, vegetation is not only controlled by N; plant species may influence ecosystem N dynamics through positive or negative effects on N cycling. We examined four potential mechanisms of plant species effects on nitrogen (N) cycling. We found no species differences...
متن کاملGlobal biogeography of microbial nitrogen-cycling traits in soil.
Microorganisms drive much of the Earth's nitrogen (N) cycle, but we still lack a global overview of the abundance and composition of the microorganisms carrying out soil N processes. To address this gap, we characterized the biogeography of microbial N traits, defined as eight N-cycling pathways, using publically available soil metagenomes. The relative frequency of N pathways varied consistent...
