Psychological Impact of Negotiating Two Cultures: Latino Coping and Self-Esteem

Among 96 Latino adults, active coping accounted for variance in global self-esteem beyond that of biculturalism and sociodemographic indicators. The findings highlight the importance of accounting for the way Latino adults approach negotiating multiple cultural contexts. Extending acculturation research to integrate competence-based formulations provides comprehensive information regarding cultural adaptation. Entre una muestra de 96 adultos Latinos, el afrontamiento activo dio cuenta de la varianza en autoestima global más allá de los indicadores de biculturalismo y sociodemográficos. Los hallazgos destacan la importancia de buscar una explicación a la forma en que los adultos Latinos enfocan la negociación de múltiples contextos culturales. Extender el ámbito de la investigación sobre aculturación para integrar las formulaciones basadas en competencia proporciona una información exhaustiva sobre la adaptación cultural

Milkshake Prices, International Reserves, and the Mexican Peso

Menu prices from 13 international restaurant franchises that operate in both El Paso and Ciudad Juarez are utilized to examine the behavior over time of the peso/dollar exchange rate. Parametric and non-parametric tests indicate that the price ratio alone provides a biased estimator of the exchange rate. In addition to the multi-product price ratio, the empirical analysis also incorporates interst rate prity and balance of payment variables. The combination of unique microeconomic sample data with national macroeconomic variables illustrates one manner in which border economies provide information regarding the interplay of financial markets between Mexico and the United States

Acculturation and Depression Among Hispanics: The Moderating Effect of Intercultural Competence

In the present study the authors examined the relative contributions of typical acculturation indicators, general coping, and intercultural competence in predicting depression among 96 Hispanic adults. The results indicated that intercultural competence served to moderate the relationship between acculturation and depression. The combination of high acculturation and high intercultural competence was associated with fewer symptoms. General coping accounted for significant amounts of variance in predicting depression, over and above traditional acculturation variables alone, suggesting that an active problemsolving style was associated with a healthier outcome. The findings are discussed within the context of integrating competence-based variables into psychological conceptualizations of cultural adaptation and the importance of group-specific abilities as potential buffers against negative mental health consequences

Modeling Kepler Transit Light Curves as False Positives: Rejection of Blend Scenarios for Kepler-9, and Validation of Kepler-9 d, A Super-earth-size Planet in a Multiple System

Light curves from the Kepler Mission contain valuable information on the nature of the phenomena producing the transit-like signals. To assist in exploring the possibility that they are due to an astrophysical false positive, we describe a procedure (BLENDER) to model the photometry in terms of a "blend" rather than a planet orbiting a star. A blend may consist of a background or foreground eclipsing binary (or star-planet pair) whose eclipses are attenuated by the light of the candidate and possibly other stars within the photometric aperture. We apply BLENDER to the case of Kepler-9 (KIC 3323887), a target harboring two previously confirmed Saturn-size planets (Kepler-9 b and Kepler-9 c) showing transit timing variations, and an additional shallower signal with a 1.59 day period suggesting the presence of a super-Earth-size planet. Using BLENDER together with constraints from other follow-up observations we are able to rule out all blends for the two deeper signals and provide independent validation of their planetary nature. For the shallower signal, we rule out a large fraction of the false positives that might mimic the transits. The false alarm rate for remaining blends depends in part (and inversely) on the unknown frequency of small-size planets. Based on several realistic estimates of this frequency, we conclude with very high confidence that this small signal is due to a super-Earth-size planet (Kepler-9 d) in a multiple system, rather than a false positive. The radius is determined to be 1.64^(+0.19)_(–0.14) R_⊕, and current spectroscopic observations are as yet insufficient to establish its mass
