    The Effects of Anger and Happiness on Opposite Valence Racial Stereotypes

    This research examines angry and happy (versus neutral) emotions and how they affect ethnic stereotyping. Research has found that both anger and happiness increase a person’s reliance on stereotype information versus neutral emotion when making social judgments. Research has also found that ethnic stereotypes are not exclusively negative, as some stereotypes make positive generalizations of certain groups. However, research on ethnic stereotypes has exclusively been presented in a negative and not a positive context. Furthermore, past studies have only focused on negatively stereotyped racial groups (e.g., Hispanics) and not positively stereotyped racial groups (e.g., Asians). This research concentrates on both positively and negatively stereotyped groups, in both a negative and a positive context, with positive and negative emotions. This experiment explores Hispanic stereotypes in both a negative and positive context for participants who were induced to be either angry, happy, or neutral. Furthermore, we included an Asian ethnic condition, which is stereotype inconsistent from the aggressive trait associated with Hispanics. Implications about the effects and limitations that anger and happiness have on increasing stereotyping versus neutrality are also discussed

    Wave Decoherence for the Random Schroedinger Equation with Long-Range Correlations

    In this paper, we study the decoherence of a wave described by the solution to a Schroedinger equation with a time-dependent random potential. The random potential is assumed to have slowly decaying correlations. The main tool to analyze the decoherence behaviors is a properly rescaled Wigner transform of the solution of the random Schroedinger equation. We exhibit anomalous wave decoherence effects at different propagation scales.Comment: 29 pages, 5 figures. arXiv admin note: text overlap with arXiv:1110.330

    Child health in rural Colombia: determinants and policy interventions

    In this paper we study the determinants of child anthropometrics on a sample of poor Colombian children living in small municipalities. We focus on the influence of household consumption, and public infrastructure. We take into account the endogeneity of household consumption using two different sets of instruments: household assets and municipality average wage. We find that household consumption is an important determinant of child health. The importance of the effect is confirmed by the two different sets of instruments. We find that using ordinary least squares would lead to conclude that the importance of household consumption is much smaller than the instrumental variable estimates suggest. The presence of a public hospital in the municipality positively influences child health. The extent of the piped water network positively influences the health of children if their parents have at least some education. The number of hours of growth and development check-ups is also an important determinant of child health. We find that some of these results only show up once squared and interaction terms have been included in the regression. Overall, our estimates suggest that both public and private investments are important to improve child health in poor environments
