A motivating factor in the development of object-oriented databases is that they reduce the impedance mismatch [Copeland and Maier 1984] between programming languages and database systems. One benefit is that a straightforward mapping between the type system of the programming language and that of the database reduces the conceptual barrier for the developer’s of database applications. Object-o...

We use three conventional inequality indices—the Gini, the coefficient of variation of income, and the relative mean deviation of income—and the Atkinson index to examine the effect of income tax rates, the minimum wage, and all the major government welfare and transfer programs on the evolution of income inequality for rural and urban areas by state from 1981-1997. We find that these programs ...

Abstract We analyse the problem of finding an allocation resources in a multiagent system that is as fair possible terms minimising inequality between utility levels enjoyed by individual agents. use well-known Atkinson index to measure and we focus on distributed approach resource allocation, where new allocations emerge result sequence local deals groups agents who agree exchange some items t...

Using only ordinal axioms, we characterize several multigroup school segregation indices: the Atkinson Indices for the class of school districts with a given …xed number of ethnic groups and the Mutual Information Index for the class of all districts. Properties of other school segregation indices are also discussed. In an empirical application, we document a weakening of the e¤ect of ethnicity...

We derive an asymptotic expansion for the Weyl function of a one-dimensional Schrödinger operator which generalizes the classical formula by Atkinson. Moreover, we show that the asymptotic formula can also be interpreted in the sense of distributions.
