These volumes present the findings of four studies of behavioral patterns of delegates at the United Nations (UN). UN voting records, delegate questionnaires, and national, political, social, and geographic variables were analyzed. The first study, "Exploring Delegate Attitudes at the United Nations," reports delegates' reactions to issues such as taxation powers for the UN and the desirability of having an international military force for the UN. Generally positive attitudes were found. However, delegates from authoritarian and developed countries tended to be more negative. The second study, "Delegate Orientations toward the United Nations: A Ten-Year Perspective," looked for attitude shifts among delegates from 1961 to 1970. It was found that underdeveloped nations and those with close U.S. relations have become more positive toward the UN, while developed nations, large nations, and those without close U.S. relations have become more negative. The third study, "Quantifying and Predicting Delegate Behavior at the United Nations," explored the predictive power of national attributes such as type of government on delegate behavior. Some were found to have predictive relevance. The final study, "Analyzing USA-USSR Support Patterns in the General Assembly," analyzed voting records for predictive patterns. Among the findings it was noted that underdeveloped nations opposed U.S. resolutions in the 23rd and 24th UN sessions, but they supported the United States in the 26th session. (BC)
