Forest ecosystems play an important role in determining the sink/source function of photosynthetic productivity.
The look and function of office productivity software, including icons like scissors and clipboards, have been slower to change.
This study aims at developing a model-based method for optimization of sugarcane straw recovery costs and internal rate of return (IRR), as a function of sugarcane productivity, straw recovery fractions and transport distances considering two recovery systems: integral harvesting (IS) and baling system (BS).
For this purpose, we estimate a regression model of occupational rates as a function of average productivity, controlling for unemployment rates and for time and region fixed effects, using the AACC data.
Thus, in theory, the degree of intergeneration transmission is an increasing function of the productivity of educational attainments, the returns to education (p) and the persistence in intergenerational inheritance of skills and other relevant characteristics, while more progressivity of public investment in education increases intergenerational educational mobility.
Using a rich panel data set of Ethiopian subsistence farmers, we estimate a distance function of grains production and find large productivity gains (approximately 33% and 29% in 1999 and 2004) from labor sharing due to synergy effects that boost labor productivity.
The optimal operating points, using productivity and yield separately as objective functions, were found and compared with the product of productivity and yield as objective function.
The results from the DSCLFP can identify desired irrigation water allocation plans under the objective function of maximizing water productivity under different confidence levels.
We develop a simple model to account for an individual's reads and cites and use it to show that the position of a person in the read-cite diagram is a function of age, innate productivity, and work history.
The logging cost is a function of harvested volume, productivity of felling, and on-site transport.
