conclusions the study found an association between the stages of change model and obesity control. results the findings indicated a statistical difference in scores of body mass index, self-efficacy scale, and health promotion lifestyle profile between the intervention and control group. patients and methods the student participants were randomly assigned to the intervention (n = 52) and contro...

background: growth failure in children less than five years old can lead to the serious complications such as increased mortality, learning difficulties or physical disability. the aim of this study was to investigate the non-organic factors affecting the growth trend in less than two years children living in zanjan, iran.   methods: this longitudinal study was conducted on a sample of 3566 chi...

We provide revealed preference axioms that characterize models of translation invariant preferences. In particular, we characterize the models of variational, maxmin, CARA and CRRA utilities. In each case we present a revealed preference axiom that is satisfied by a dataset if and only if the dataset is consistent with the corresponding utility representation. Our results complement traditional...

As the speed and the dynamic range of computer networks evolve, the issue of e cient tra c management becomes increasingly important. This work describes an approach to tra c management using explicit rate information provided to the source by the network. We present an asynchronous distributed algorithm for optimal rate calculation across the network, where optimality is understood in the maxm...

We study a nonzero-sum game of two players which is a generalization of the antagonistic noisy duel of discrete type. The game is considered from the point of view of various criterions of optimality. We prove existence of ε-equilibrium situations and show that the ε-equilibrium strategies that we have found are ε-maxmin. Conditions under which the equilibrium plays are Pareto-optimal are given.

Invoking the parametrized distribution formulation of agency theory, the paper develops axiomatic foundations of the principal’s and agent’s choice behaviors that are representable by the maximization of the minimum expected utility over actiondependent sets of priors. In the context of this model, the paper also discusses some implications of uncertainty aversion for the design of optimal ince...

The existence of the value for stochastic games with finitely many states and actions, as well as for a class of stochastic games with infinitely many states and actions, is proved in [2]. Here we use essentially the same tools to derive the existence of the minmax and maxmin for n-player stochastic games with finitely many states and actions, as well as for a corresponding class of n-person st...

In this paper we analytically propose an alternative approach to achieve better fairness in scheduling mechanisms which could provide better quality of service particularly for real time application. Our proposal oppose the allocation of the bandwidth which adopted by all previous scheduling mechanism. It rather adopt the opposition approach be proposing the notion of Maxmin-charge which fairly...
