Among the different approaches to investigate in detail the extinction of population of rare species the Birth and Death process has given the simplest approach to settledown the solution. Here, an attempt is made to obtain the extinction probabilities and to generate a different levels of population sizes. A random quadtree method is footforth. We give the basic concepts and results used in th...

Population density varies widely among U.S. metro areas. A simple, static general equilibrium model demonstrates that moderate differences in metro areas’ consumption amenities can cause extremely large differences in their population density. Such amenities are more strongly capitalized into housing prices than into wages. Empirical results suggest that amenities do indeed help to support high...

This includes efforts to influence determinants of health as well as more direct health-improving activities. A health system is therefore more than the pyramid of publicly owned facilities that ...

In order to quantitatively analyze plant root growth and construct plant root growth model, a root system representation model based on tree-form data structure is proposed in this paper. After processing and analyzing root image, the information of root, such as length, diameter, number of child root, position of child root, angle of child root etc., is stored in a node of this treeform data s...

Hostility towards a population, whether on religious, ethnic, cultural or socioeconomic grounds, confronts rulers with a trade-off between taking advantage of population members’ eagerness to maintain their identity and inducing them to “comply” (conversion, quit, exodus or any other way of pleasing the hostile rulers). This paper first analyzes the rulers’ optimal mix of discriminatory and non...

Computees are abstractions of the entities that populate global and open computing environments. The societies that they populate give an institutional meaning to their interactions and define the allowed interaction protocols. Social integrity constraints represent a powerful though simple formalism to express such protocols. Using social integrity constraints, it is possible to give a formal ...
