Using data envelopment analysis techniques that allow calculation of a generalized version of the traditional distance function model for productive efficiency, we find pervasive levels of inefficiency and a typology of different research strategies.
"You are not going to be able to focus on the future if the past has got you by the throat," said Allen, who believes that a holistic model for productive change has to start with tidying up your past.
Its main scientific objective is to explore the potential of biodiversity and ecological processes such as pest regulation, enabling novel ecologically-based models for productive systems, reduction of pesticide use, and adaptation or resilience of farming systems in the face of environmental disruptions.
Mayor Rudolph W. Giuliani would have done well in his speech on the state of New York City to cite Giuseppe Verdi as a role model for a productive old age.
Why Philanthropy Matters takes an in-depth look at philanthropy as an underappreciated force in capitalism, measures its critical influence on the free-market system, and demonstrates how American philanthropy could serve as a model for the productive reinvestment of wealth in other countries.
Those of us who care about preserving the rich legacy of yoga in its fullness can only hope that he will be remembered not just as an asana master, and not just as a role model for vigorous and productive aging, but as a guru who recognized the complete range of the tradition's practical, philosophical and spiritual glories.
The PDGFRα DFG-out models scores highly using various measures, including the statistical potential Z-DOPE (−1.21) as well as the enrichment values AUC (0.82) and logAUC (33.4), which suggest that the models are sufficiently accurate for productive virtual screening (Table 2).
Indeed, the evolution of plants and animals in response to artificial selection is increasingly seen as a very productive model for studying general questions about adaptive evolution (e.g., Gepts 2004; Ross-Ibarra et al. 2007).
Together theses results suggest that the proposed system based on spike-timing patterns gives a productive model for the study of detailed learning and memory dynamics.
We argue that a productive model for the investigation we advocate will almost certainly involve a combination of simple individual models and simple but demographically accurate population representations.
The distinctive wealth of this class of secreted protein in H. mustelae, the evidence for their production (see below) and the likelihood of their involvement in host interaction, make this bacterium a potentially productive model for exploring autotransporter evolution and biological function.
