Academy of Political Science http://www.psqonline.org/
“The Academy of Political Science (APS), founded in 1880, promotes objective, scholarly analyses of political, social, and economic issues. Through its conferences and publications APS provides analysis and insight into both domestic and foreign policy issues.
Due to its well established effort to provide analysis on domestic and foreign affairs, the Academy enjoys a special prestige among the many institutions, committees and think tanks devoted to the exploration and exposition of public policy. More important than mere longevity are the depth and breadth of intellectual competence that the Academy's members bring to their chosen fields. Furthermore, there is the assurance that all publications of the Academy are not shaped by ideological or partisan considerations.”
American Academy of Social and Political Science http://www.aapss.org/
“The American Academy of Political and Social Science was created in 1889 to promote the progress of the social sciences. It did so by creating a forum in which research on contemporary political, economic, and social issues could help inform public policy as well as enlighten the intellectually curious. The Annals, the Academy's bimonthly journal, and the Academy's annual meetings, symposia, and special publications have served as vehicles through which its objectives have been achieved for nearly 115 years. Its new programs will help advance these achievements further.”
