Measuring Mine Soil Productivity for Forests

Soil carbon stabilization along climate and stand productivity gradients in black spruce forests of interior Alaska1

The amount of soil organic carbon (SOC) in stable, slow-turnover pools is likely to change in response to climate warming because processes mediating soil C balance (net primary production and decomposition) vary with environmental conditions. This is important to consider in boreal forests, which constitute one of the world’s largest stocks of SOC. We investigated changes in soil C stabilizati...

Measuring Medical Care Productivity

MEASURING productivity is a central challenge in medical care, as it is in all other service indus­ tries. Medical care is particularly important, however, because of the enormous share of gross domestic prod­ uct (GDP) that it takes. The United States spent $2 tril­ lion dollars, or 16 percent of GDP, on health care in 2005 (Catlin, et al. 2007). This compares with a me­ dian of 8.5 percent am...

Measuring HPC Productivity

One key to improving high-performance computing (HPC) productivity is finding better ways to measure it. We define productivity in terms of mission goals, i.e., greater productivity means that more science is accomplished with less cost and effort. Traditional software productivity metrics and computing benchmarks have proven inadequate for assessing or predicting such end-to-end productivity. ...

Measuring Productivity Changes in Academic Units

In this study, the productivity changes of industrial and comprehensive universities have been measured using the Malmquist Index based on data envelopment analysis in the period of 2013-2014 and 2014- 2015. The input variables include the number of faculty members, the number of newly enrolled students, the number of staff, and total expenses; the output variables also include the number of cu...
