⁵ Members of Congress have also attended the Commonwealth Parliamentary Association meetings as observers, Anglo-American meetings, and occasional bilateral meetings with other parliamentarians. Such activities have not been institutionalized. The most extensive records of the groups' formal activities can be found in the reports submitted by individual delegations to the Senate and the House.

⁹ Congressional Quarterly provides aid and comfort to the opponents of congressional travel such as columnist Jack Anderson in its annual compilation of foreign travel. The symbolic categorization of travel as “junkets” accomplishes the same end. While some foreign travel expense is hidden in the appropriations for the Departments of Defense and State, most must be approved by the respective houses and reports filed. Domestic travel funds are not, however, publicly reported. In fact, a staff member of the House Administration Committee told us that the policy was to discourage non-congressional examination of such expenditures. Reaction to criticism was behind policy changes to further restrict access to travel records.

¹¹ The procedure followed parallels that used by MacRae, Duncan Jr in Issues and Parties in Legislative Voting: Methods of Statistical Analysis (New York: Harper and Row, 1970)Google Scholar. Tetrachoric r statistics measuring one-way association were subjected to the principal components analysis, rather than Yule's Q, to extract latent cumulative or Guttman scales in the roll calls. Only the first component was used to calculate component scores since only one significant component emerged in each year as judged by the relative sizes of the latent roots. The cumulative model is discussed further in Clausen, Aage, How Congressmen Decide (New York: St. Martin's Press, 1973)Google Scholar, Chapter 2 and in Weisberg, Herbert F., “Dimensional Analysis of Legislative Roll Calls,” unpublished doctoral dissertation, Department of Political Science, University of Michigan, 1968Google Scholar. Up to 1970, the unidimensional cumulative model was the underlying response model in both houses. Since 1970, many Senators and Representatives have been acting in accordance with a proximity model.

¹² Individual scores were standardized by subtracting the mean for the roll call from the individual's vote, coded 1 for yea and 0 for nay, and then dividing by the standard deviation for the roll call.

¹³ Tests of hypotheses about means and the difference between two means will use the t statistic as an approximate standard. Since the populations of delegates deviate from normality, and the standard deviations of scores in different subsets of the population are probably not equal, t statistics are not precisely correct. As a rough guide, a value should be at least two times its standard error to be significant at the 0.05 level. See Freund, John E., Mathematical Statistics (Englewood Cliffs, N.J.: Prentice Hall, 1962)Google Scholar.

Democrats have tended to be more internationalist than Republicans in both houses, and both bodies demonstrate relative stability in scale scores from session to session. The average correlations between principal component scores in adjacent sessions are +0.84 in the House and +0.83 in the Senate, while the values with one session intervening are +0.79 and +0.77 respectively. These are consistent with the comparable values of tau beta correlations between the foreign policy scales for the 85th and 86th Congresses of +0.75 for Democratic Representatives and +0.80 for Republicans. Mean changes in score between adjacent sessions were also trivial as they should have been over each house. If the same members were represented with scores in each session, the mean difference would be identically zero because the means of each session are identical.

¹⁴ The Americans for Democratic Action (ADA) and the Committee on Political Education (COPE) of the AFL-CIO both rate the voting records of members of Congress each year. The two groups use different sets of roll calls to evaluate the extent to which legislators agreed with the organization's preferred votes. We dichtotomized both ratings at 50 percent and classified Congressmen according to which of the four cells they occupied. Congressmen lower than 50 percent on both measures were categorized as “conservatives,” while those higher than 50 percent on both measures were denoted as “liberals.” Most individuals fell into these two cells. The rest fell mainly into the cell lower than 50 percent on the ADA score, but greater than 50 percent on the COPE rating, and were denoted “mixed.” One percent occupied the fourth cell and were included in the liberal category.

¹⁹ The immigration bill before Senator Ervin's subcommittee would have imposed hemispheric quotas on immigrants to the United States. Specifically, managerial personnel transferred from Canada to the United States by multinational companies could enter, but their families would have had to wait in line. Senators Ervin and Aiken were lobbied by Canadian parliamentarians at a meeting of the Canada-United States group. Thereafter, the provision was altered by Senator Ervin.

²⁵ Experimental regression is a tendency for individuals with extreme scores at one time to be less extreme at the next, independent of the effect of any causally relevant variables. See Runkel, Philip J. and McGrath, Joseph E., Research on Human Behavior: A Systematic Guide to Method (New York: Holt, Rinehart and Winston, 1972), pp. 39–40Google Scholar. Convergence is a tendency for extreme individuals at one time to move toward a mean value after elaboration with a causally relevant variable. The fact that the Democratic average score has become more internationalist supports convergence rather than regression. See Pool, et. al., “The Influence of Foreign Travel,” p. 161.
