In this paper we consider the classical problem of dividing a land among many agents so that everybody is satisfied with the parcel she receives. In the literature, it is usually assumed that all the agents are endowed with cardinally comparable, additive, and monotone utility functions. In many economic and political situations violations of these assumptions may arise. We show how a family of...

The phenomenon of urban sprawl on agricultural lands is a suffered by all the poor and rich countries world. This has represented challenge to most world, especially developing ones, whose population increased at high rates, consequent pressures resources, surrounding lands, whether in cities or villages. There no doubt that land encroachment one serious problems facing Egypt present time. It s...

Indonesia is an agricultural country with abundant natural wealth of products. Moreover, it stays in a strategic geographical position, located the tropical climate, and having high rainfall. Competent enterprise management can help adapting to ever-changing human needs. It also maintain even improve quality environment. To maximize resource management, land necessity. Land affected by several ...

We consider whether current notions about superstring theory below the Planck scale are compatible with cosmology. We find that the anticipated form for the dilaton interaction creates a serious roadblock for inflation and makes it unlikely that the universe ever reaches a state with zero cosmological constant and time-independent gravitational constant. Superstring theories have been extensive...

We study boundary renormalization group flows of N = 2 minimal models using Landau-Ginzburg description of B-type. A simple algebraic relation of matrices is relevant. We determine the pattern of the flows and identify the operators that generate them. As an application, we show that the charge lattice of B-branes in the level k minimal model is Zk+2. We also reproduce the fact that the charge ...

"In this paper the author introduces a population-projection framework that incorporates interregional migration and intraregional residential mobility streams to project future population sizes both across and within regions in a manner that is consistent with existing migration theory. The author presents a general matrix model of the framework, shows how its parameters can be estimated from...

security as one of the basic human needs has a special place in relaxation, comfort and spiritual needs provision. for this reason, security is always of managers, planners, architects and urban designers' interest. solutions and strategies of security provision have been fundamentally changed following prevailing change of housing architecture patterns from homes to residential complexes ...

Abstract This study integrates novel data on 100-year flood hazard extents, exposure of residential properties, and place-based social vulnerability to comprehensively assess compare risk between Indigenous communities living 985 reserve lands other Canadian across 3701 census subdivisions. National-scale properties fluvial, pluvial, coastal flooding was estimated at the return period. A index ...
