Leonora N. Panlasigui, Cecille Bayaga, Erniel B. Barrios, and Kim Cochon. 2010. “Glycaemic Response to Quality Protein Maize Grits,” Journal of Nutrition and Metabolism, 201, 697842, Pp. 1-6. Publisher's Version Abstract
Background. Carbohydrates have varied rates of digestion and absorption that induces different hormonal and metabolic responses in the body. Given the abundance of carbohydrate sources in the Philippines, the determination of the glycaemic index (GI) of local foods may prove beneficial in promoting health and decreasing the risk of diabetes in the country. Methods. The GI of Quality Protein Maize (QPM) grits, milled rice, and the mixture of these two food items were determined in ten female subjects. Using a randomized crossover design, the control bread and three test foods were given on separate occasions after an overnight fast. Blood samples were collected through finger prick at time intervals of 0, 15, 30, 45, 60, 90, and 120 min and analyzed for glucose concentrations. Results. The computed incremental area under the glucose response curve (IAUC) varies significantly across test foods (P < .0379) with the pure QPM grits yielding the lowest IAUC relative to the control by 46.38. Resulting GI values of the test foods (bootstrapped) were 80.36 (SEM 14.24), 119.78 (SEM 18.81), and 93.17 (SEM 27.27) for pure QPM grits, milled rice, and rice-QPM grits mixture, respectively. Conclusion. Pure QPM corn grits has a lower glycaemic response compared to milled rice and the rice-corn grits mixture, which may be related in part to differences in their dietary fibre composition and physicochemical characteristics. Pure QPM corn grits may be a more health beneficial food for diabetic and hyperlipidemic individuals.

An analytical building model including the nonlinear e®ects caused by gravity is presented in this paper. Governing equations are derived for both single-degree-of-freedom (SDOF) and multi-degree-of-freedom (MDOF) models with large displacements taken into account, and solutions are obtained by direct integration and modal analysis. The response of typical structures subjected to harmonic ground excitation was expressed in exact and approximate forms, compared with the response of an equivalent shear building. Numerical examples show that while gravity generally decreases the natural frequency of elastic SDOF systems with small displacement approximations, actual natural frequency increases with ground motion. The di®erence in the natural frequency and response of MDOF systems to the equivalent shear building is not only due to gravity, but also caused by the geometry of the structure. Exact solution shows that the frequency varies with ground motion amplitude.

Keywords: Flexure building; gravity e®ect; nonlinearity; analytical building; building model.

Alellie D. Sobrevinas and Erniel B. Barrios. 2010. “Impact of the Rice Trade Policy Reforms on Household Welfare in the Philippines.” Philippine Journal of Development, 68, 1, Pp. 15-39. Publisher's Version Abstract
The effects of rice trade policy reforms on household welfare, as indicated by changes in consumer and producer prices, are analyzed using nonparametric regression and density estimation. Since many households in the Philippines are consumers and producers of rice, the net benefit ratio (NBR) was used to measure the change in household welfare given changes in prices. The impact of a policy change is not the same across different groups of households. Thus, varying welfare effects should be considered in designing policy interventions. Among the different rice trade policy scenarios, the elimination of quantitative restriction and full tariff reduction can lead to highest gains in household welfare in the long run.

A new method for wave propagation modeling is introduced in this paper. By using the constraint optimization (Lagrange multiplier) method, the sum of weighted squared Fourier amplitudes is minimized when subjected to a constraint. The sum of the maximum amplitudes obtained from all output models is normalized to unity and is taken as a constraint. In this method, all the actual time histories are considered as outputs and dealt with equally. Independently of the combinations of time histories (or the first time history selected) during the analysis, the method captures the relationship of actual time histories by showing clear peaks. This paper describes the formulation of the models and illustrates the advantage of this method over the normalized input-output minimization (NIOM) method. The Mod-NIOM is then used to analyze the time histories of the Hyogoken-nanbu earthquake recorded at the Port Island vertical array site in Kobe, which suffered from liquefaction caused by the strong motions during the main shock. This method showed good correlations between the observed time histories at the site even though the surface time history was greatly modified by the liquefaction.

Using data from the 2003 Family Income and Expenditure Survey (FIES) and 2005 community-based monitoring system (CBMS) for a city, Multivariate Adaptive Regression Splines (MARS) is used in identifying household poverty correlates in the Philippines. Models produced by MARS are more parsimonious, yet contain theoretically and empirically sound set of household poverty correlates and have high accuracy in identifying a poor household. MARS provides a better alternative to logistic regression for a more efficient and effective implementation of a proxy means test in the identification of potential beneficiaries of poverty alleviation programs.

Family structure, household resources, numbers of siblings competing for those resources, and parents’ own educational attainment are often important predictors of children’s education outcomes. Overseas migration of parents from the Philippines has resulted in increasing numbers of long-term separations of parents from each other and from their children. Western-based analyses might predict negative education outcomes for children as a result of parental absence. We find that separations caused by overseas migration often are either neutral or can have positive effects on schooling outcomes, at least among older children. Girls fare better in terms of educational attainment than do boys overall. Boys are often more affected by background variables, including parents’ international migration.
