Low rates of disclosure among Latina survivors of sexual assault and intimate partner violence may be related to cultural influences that stigmatize disclosure and make identifying instances of sexual assault and intimate partner violence difficult. In an effort to add to existing literature, the current study conducted a series of 10 focus groups with Spanish-speaking Latinas of varying educational, immigration, and generational statuses to identify the range of cultural influences that affect Latinas' ability to identify and disclose instances of sexual assault and intimate partner violence. Results suggested that gender role ideologies, traditional beliefs about marriage, familism, taboos against talking about sex, respect for authority, lack of community resources, and fear of violence operate in different ways to obscure and justify acts of sexual assault and intimate partner violence and to maintain silence when such acts do occur. Yet, most participants also felt that other people, particularly Latinos living abroad and the older generation of Latinas living in the United States, held far more conservative and traditional beliefs than the participants themselves did, suggesting that important differences exist in both the acceptance of cultural beliefs and the mechanisms through which these beliefs affect Latinas' ability to identify and disclose instances of sexual assault and intimate partner violence. Implications of these findings are discussed.

Solubility measurements of several nonpolar gases (He, Ne, Ar, Kr, Xe, H2, D2, N2, CH4, C2H4, C2H6, CF4, SF6, and CO2) in 2-methylcyclohexanone at 273.15–303.15 K and a partial pressure of gas of 101.32 kPa are reported. Thermodynamic functions (Gibbs energy, enthalpy, and entropy) for the solution process at 298.15 K and 101.32 kPa partial pressure of gas are evaluated. Use is made of the Scaled Particle Theory applied to gas solubility for determining Lennard-Jones (6, 12) pair-potential parameters and temperature dependence of the effective hard-sphere diameter of the solvent. The values that this theory predicts for the solution thermodynamic functions are also calculated. Keywords: 2-methylcyclohexanone, gas solubility, thermodynamic functions of solution, Henry coefficient, scaled particle theory.

A method to design a dialyte based on the caustic surfaces is presented, with correction at the third-order spherical aberration. We predefined, a priori, the value for the back focal length of the separated doublet for two different wavelengths to calculate their radii of curvature, which depend on all the parameters involved in the refraction process. Additionally, we approached the caustic surface by applying a Taylor series, which provided the analytical spherical aberration coefficient at the third order. Two alternatives to design achromatic separated doublets are provided. Finally, we extended the method to design achromatic cemented triplets.
