The use of asset indices in welfare analysis and poverty targeting is increasing, especially in cases in which data on expenditures are unavailable or hard to collect. We compare alternative approaches to welfare measurement. Our analysis shows that inferences about inequalities in education, health care use, fertility, and child mortality, as well as labor market outcomes, are quite robust to ...

Many multiagent domains where cooperation among agents is crucial to achieving a common goal can be modeled as coalitional games. However, in many of these domains, agents are unequal in their power to affect the outcome of the game. Prior research on weighted voting games has explored power indices, which reflect how much “real power” a voter has. Although primarily used for voting games, thes...

We define real-valued characteristic classes of flat complex vector bundles and flat real vector bundles with a duality structure. We construct pushforwards of such vector bundles with vanishing characteristic classes. These pushforwards involve the analytic torsion form in the first case and the eta-form of the signature operator in the second case. We show that the pushforwards are independen...

A mediator join index (MJI) is proposed to speed up Nway inter-database joins by reducing the amount of data transfer during evaluation. A family of algorithms, the Query Scrubbing Algorithms (QSA), are developed to maintainMJI and to evaluate queries usingMJI. QSA algorithms use query scrubbing to cope with update and query anomalies related to materialized views in the mediator context. Compa...

1. Introduction A process capability index is a numerical summary that compares the behavior of a product or process characteristic to engineering specifications. These measures are also often called capability or performance indices or ratios; we use capability index as the generic term. A capability index relates the voice of the customer (specification limits) to the voice of the process. A ...

Metaphase chromosomes from leukocyte cultures of Indian subjects have been measured. Mean length index and arm ratios compare well with figures from other parts of the world-except chromosome No. 2 which in a large percentage of cases is longer than Ch: No. 1. The fallacies involved in measuring and basing correlations on these are discussed. Introduction The characteristics of the normal human...

It is well known that positive linear systems have differences in the concepts and characterizations of the structural properties of reachability and controllability. In this paper, the reachability indices of a positive system are defined and consequently they are studied. For that, a canonical form of the reachability indices is given by positive similarity. From that canonical form, it is es...

Using separate indices for each element and merging their results has proven to be a feasible way of performing XML element retrieval; however, there has been little work on evaluating how the main method parameters affect the results. We study the effect of using different weighting models for computing rankings at the single index level and using different merging techniques for combining suc...

Topological indices have important role in theoretical chemistry for QSPR researches. Among the all topological indices the Randić and the Zagreb indices have been used more considerably than any other topological indices in chemical and mathematical literature. Most of the topological indices as in the Randić and the Zagreb indices are based on the degrees of the vertices of a connected graph....
