The 14C-bicarbonate method of primary productivity measurement was modified for dense algal cultures by the addition of NaHCO3 to avoid exhaustion of carbon source. Using this method plus a modified procedure for scintillation counting of limited sample size, six species of chlorophyean algae were ...

Primary production in the deep sea by chemosynthetic bacteria is another example of a productivity that is of no more than local importance. At the end of this chapter readers may be left with the conclusion that one can hardly speak of an "art" when the methods for the measurement of ...
A way of computing quality and quantity components of overall productivity is employed. Findings – The case study is an application to the Swedish primary and secondary school system over the 1992 to 1995 period. It was found that quality "matters", i.e. productivity growth changes when one ...

The approach is applied to analyze educational production of Ohio school districts. Applying the extended approach in an analysis of the educational production of 604 school districts in Ohio, we find changes in environmental harshness are the primary drivers in productivity changes of underperforming ...

The rising costs of Research and Development (R&D) and the increasing dependence of companies on technology for competitive advantage are causing both external investors and managers to seek better measures of R&D productivity and effectiveness. One major difficulty in evaluating R&D ...
Productivity Costs Measurement Through Quality of Life? A Response to the Recommendation of the Washington Panel This paper comments on the recently published guidelines of the Washington Panel on incorporation of indirect non锕巈dical costs, or productivity costs, in......
Consequently, to carry out green development more accurately and scientifically, the primary task is to conduct scientific research and judge the relationship among regional resources, environment, and economy. Therefore, it's of tremendous significance to study the green total factor productivity (GTFP...
