Partonic State and Single Transverse Spin Asymmetry in Drell-Yan Process

Single transverse-spin asymmetries have been studied intensively both in experiment and theory. Theoretically, two factorization approaches have been proposed. One is by using transverse-momentum-dependent factorization and the asymmetry comes from the so called Sivers function. Another is by using collinear factorization where the nonperturbative effect is parameterized by a twist-3 hadronic matrix element. However, the factorized formulas for the asymmetries in the two approaches are derived at hadron level formally by diagram expansion, where one works with various parton density matrices of hadrons. If the two factorizations hold, they should also hold at parton level. We examine this for Drell-Yan processes by replacing hadrons with partons. By calculating the asymmetry, Sivers function and the twist-3 matrix element at nontrivial leading order of $\alpha_s$, we find that we can reproduce the result of the transverse-momentum-dependent factorization. But we can only verify the result of the collinear factorization partly. Two formally derived relations between Sivers function and the twist-3 matrix element are also examined with negative results.Comment: 15 pages, 6 figure

Trade Liberalization in Latin America and Eastern Europe: The Cases of Ecuador and Slovenia

This paper analyzes the potential effects of two ongoing trade liberalization experiences: Ecuador signing a Free Trade Agreement with the United States and Slovenia joining the European Union as a full member. We construct a static Applied General Equilibrium Model and perform a numerical experiment that consists on eliminating all import tariffs that Ecuador and Slovenia impose on the United States and European Union, respectively. To calibrate our models, we work with Input-Output tables and construct a Social Accounting Matrix for each country. We perform additional numerical experiments, such as sensitivity analysis on the import and export elasticities of substitution, a partial liberalization scenario, the fiscal impact of eliminating the tariff revenues and how this loss can be compensated with other taxes, and an alternative trade liberalization framework for Slovenia. We find that both countries benefit from these trade liberalization reforms, with prices falling in the import sector and production rising in the export sector. However, different forms of trade liberalization (free trade agreement vs. customs union) have different implications on the patterns of trade and welfare.Trade Liberalization; Free Trade Agreement; Customs Union; Fiscal Policy; Social Accounting Matrix; Ecuador; Slovenia

Welfare Impact of Trade Liberalization

This paper constructs a static Applied General Equilibrium Model and analyzes the distributional impact of trade reforms. To calibrate our model, we work with the Household Expenditure Survey to disaggregate household groups by income, age, and skill intensity, and the Input-Output table to construct a Social Accounting Matrix. Our benchmark simulation looks at Slovenia joining the European Union. We then compare with two alternative scenarios: a free trade agreement between Slovenia and the EU, and an alternative fiscal arrangement of distributing tariff revenues under the EU. While trade reforms lead to falling prices in the import sector, rising production in the export sector, and improvement in aggregate welfare, the distributional impacts across household groups vary in its degree.Trade Liberalization; Free Trade Agreement; Customs Union; Social Accounting Matrix; Household welfare

Development of a Community-Based Spiritual Life Review Program for Promoting Resilience of Elders Residing in Disaster-Prone Areas

Background: Nowadays disasters are a common occurrence in the world. The elderly are in a vulnerable condition in terms of disasters and need help to recover from the hardship caused if they are caught in such a disaster. Two significant contributors to elderly people having sufficient resilience to be able to deal with such disasters are spiritual support and social support. Purpose: To develop a program specifically for Muslim elderly in Indonesia for promoting resilience. Method: The processes of developing the program were conducted in 2011, and included a critical review of the literature, constructing the elements of the actual program, validating the contents of the program by three experts, revising the program according to the experts‟ suggestions, and finally pilot-tested the final version of the program on a group 12 elders in Banda Aceh, Indonesia. Result: The program protocol established in this program includes five stages: (1) reviewing individual spiritual life experiences using memorable photos; (2) appreciating feelings among group members (3) re-evaluating the participant‟s life by looking to the group‟s album, (4) reconstructing the participants‟ life, and (5) affirming the six spiritual dimensions of the Islamic religion by the religious leader
