The 1993 Survey of Household Income and Wealth, a large cross-section of the Italian population covering 24,000 individuals, reports detailed information on children’s attendance of public and private schools and parents’ assessments of the quality of public schools in the city of residence. The survey also provides detailed information on the household’s demographic structure, income and paren...

M. H. Bond (2002), A. P. Fiske (2002), S. Kitayama (2002), and J. G. Miller (2002) joined D. Oyserman, H. M. Coon, and M. Kemmelmeier (2002) in highlighting limitations of the individualism-collectivism model of culture. Concern is warranted; nevertheless, individualism-collectivism helps structure discourse on the influence of culture on the mind. To avoid level-of-analysis entanglements, Oyse...

The performance of the state estimation (SE) depends on the accuracy of the received measured data, as well as the parameter data of the power system. In this paper, a new algorithm is proposed for the simultaneous identification and correction of measurement and branch parameter errors (series and shunt admittances) in the power system SE problem. The proposed method uses Lagrange multipliers ...

Power system component failures can generally be classified into two categories: repairable random failures and aging failures. An essential step in power system reliability evaluation is the calculation of component unavailability. The paper presents a new model for calculating the unavailability due to aging failures using the normal distribution. It is based on the strictly mathematical deri...
