A mail survey of Nigerian immigrants in Dallas, Texas, and Chicago, Illinois, was conducted during October and November 1995. Four hundred and sixty-eight Nigerian immigrant families in the two cities were selected by systematic sampling through the telephone books. Return rate was approximately 40% (187). The variables included in the study were media exposure variables, general demographics, immigration traits, U.S. demographics, Nigerian demographics, and political and cultural traits. New variables which had not been included in previous studies were also tested in this study: television talk shows, talk radio, diffuse support for the U.S. political system, authoritarianism, self-esteem, and political participation. This study employed multiple regression analysis and path analysis of the data. This study found that Nigerian immigrants have high preference for television news as their main source of political information. This finding is in consonance with previous studies. Nigerian immigrants chose ABC news stations as their number one news station for political information. Strong positive associations existed between media exposure and length of stay in the United States and interest in U.S. politics. Talk radio positively associated with interest in U.S. politics and negatively associated with length of stay in the United States. Thus, this finding likely means …

From Abstract: This report provides background and procedural information for the use of a general-purpose Stirling-engine analysis code developed at Argonne National Laboratory and available through the National Energy Software Center. Different engine configurations are easily specified, or the user may make use of provided data for existing engines, both kinematic and free piston. The code models heat transfer and fluid mechanics throughout the engine and accounts for system energy flows and losses. Good agreement is shown between code predictions and experimental measurements. The present analysis method was chosen for fast execution and useful information on energy flows in the system. A description is provided of the code structure that is intended to accept different analysis modules that can provide improved system modeling or optimization capability.
