The CO2 balance of unproductive aquatic ecosystems

Community respiration (R) rates are scaled as the two-thirds power of the gross primary production (P) rates of aquatic ecosystems, indicating that the role of aquatic biota as carbon dioxide sources or sinks depends on its productivity. Unproductive aquatic ecosystems support a disproportionately higher respiration rate than that of productive aquatic ecosystems, tend to be heterotrophic (R > ...

David Oliver: Unproductive activity and NHS consultants.

With constrained public money, a growing focus arises on doctors’ key role in reducing variation in processes and outcomes and improving value in healthcare, especially how money is spent and what it delivers in outcomes that matter to patients and system efficiencies. Earlier this year John Appleby published an analysis in The BMJ comparing current and historical productivity of NHS consultant...

Knowing When to Abandon Unproductive Learning

Autonomous learning is the ability to learn effectively without much external assistance, which is a desirable characteristic in both engineering and computationalmodeling. We extend a constructive neural-learning algorithm, sibling-descendant cascade-correlation, to monitor lack of progress in learning in order to autonomously abandon unproductive learning. The extended algorithm simulates res...

Learning How Productive and Unproductive Meetings Differ

In this work, we analyze the productivity of meetings and predict productivity levels using linguistic and structural features. This task relates to the task of automatic extractive summarization, as we define productivity in terms of the number (or percentage) of sentences from a meeting that are considered summary-worthy. We describe the traits that differentiate productive and unproductive m...
