Water transfers from agricultural to urban and environmental uses will likely become increasingly common worldwide. Many agricultural areas rely heavily on underlying groundwater aquifers. Out-of-basin surface water transfers will increase aquifer withdrawals while reducing recharge, thereby altering the evolution of the agricultural production/groundwater aquifer system over time. An empirical...

It is argued that the most important property of a suitable model of parallel computation is that it correctly predicts which algorithms is the most efficient in practice, and it is shown that models that do not reward block transfers do not always fulfill this requirement. We also discuss if the algorithm developer should have to specify the order in which messages are sent, and how these issu...

The paper considers social welfare functions and ethical inequality measures for linear inequality concepts when households may differ in needs. The welfare functions are nested, i.e. separable in the level of welfare attained by the homogeneous subpopulations, and possess a homogeneity property depending on the inequality concept imposed. Several principles of transfers between different house...

Fiscal Federalism and Risk Sharing in Germany: the Role of Size Differences by Kai A. Konrad and Helmut Seitz We study the effect of size differences for an optimal risk sharing system of intergovernmental transfers in Germany. The German fiscal transfer system should account for the fact that an optimal insurance mechanism has the property that smaller states contribute a smaller share of thei...

We define an interpretation of modal languages with polyadic operators in modal languages that use monadic operators (diamonds) only. We also define a simulation operator which associates a logic Λ in the diamond language with each logic Λ in the language with polyadic modal connectives. We prove that this simulation operator transfers several useful properties of modal logics, such as finite/r...

The security of farmland property rights is an important factor that affects investment and succession, farm succession highly significant for achieving sustainable agricultural development. In this study, based on survey data obtained from 1012 apple growers in Shandong Shaanxi Provinces, we analyzed the impact land tenure willingness farmers related paths by constructing binary logistic regre...

In this paper, we study the impact of housing reform and the rapid development of the housing market in China on intergenerational transfers and elderly well-being. During the 1990s, the Chinese government gave property rights to many urban residents who had been allocated housing by their danwei employers. These unexpected windfalls were substantial in size, and grew with the rapid increase in...

in this article using the inverse laplace transform, we show analytical solutions for the generalized mass transfers with (and without) a chemical reaction. these transfers have been expressed as the couette flow with the fractional derivative of the caputo sense. also, using the hankel contour for the bromwich's integral, the solutions are given in terms of the generalized airy functions.
