This journal issue concerns research projects conducted at the Hispanic Research Center of Fordham University in New York City. In the first article, Luis R. Marcos discusses research on the psychiatric evaluation and psychotherapy of bilingual Hispanic patients, focusing primarily on linguistic factors which affect evaluation and treatment of the Hispanic population. A number of specific diagnostic and treatment strategies are evaluated and recommendations for mental health professionals who deal with bilingual patients are offered. In the second article, "Alternative Models of Service Delivery for the Hispanic Elderly," Marta Sotomayor claims that existing services have not kept pace with the needs of the Hispanic elderly and suggests the use of social and familial networks to close the gap. In the final article, "Undocumented Migration: Issues and Trends," Elizabeth Collado discusses a lecture presented by Dr. Charles Keely, including an overview of U.S. immigration policies and their effect on undocumented immigration. The article contends that immigrants themselves have been the victims of economic hard times in the United States, and that their negative impact on the economy has been exaggerated. Increasing immigration quotas and dropping the country of origin specification are recommended as policy reforms. (AOS)
