This study explains how threats to soils and soil services are linked to agricultural soil management, how threats can be mitigated, and which barriers complicate this. It highlights trade-offs and synergies that exist between different interests affected by soil management, such as climate...

In this paper we present a theoretic two-stage model for retailers location and consumers purchase decision. Retailers decision problem is formalized in terms of a zero-sum game, whose payoffs refers to retailers' market share and consumers decision problem is formalized in terms of a discrete...

It is well known that the Poisson–Boltzmann (PB) equation yields the exact counterion density around charged objects in the weak coupling limit. In this paper, we generalize the PB approach to account for coupling of arbitrary strength by making use of Tsallis q-exponential distributions. Both...

The factor demand is modeled for Italy, Portugal and Spain. We estimated a translog cost function with capital, labor and energy over the 1980-1996 period. Our objective regarding energy as input was two-fold: on the one hand, to verify its incorporation as a productive factor, and, on the...

In the present work we conceptualize energy as a productive input observing its relationship with capital and labor. A translog cost function is used to study the factor demand in the economies of Portugal and Spain, without a priori fixing any given technological structure. We evaluate the...
