POL 290C: Political Networks: Methods and Applications Exercise #2: Network Conversion and Due: January 16, 2007 (in class) 1. Converting Affiliation Matrices into Sociomatrices. Using Maoznet apply the conversion program using the three methods of conversion discussed in class. To do that, take the following steps. Note: Please reload the Maoznet program, as it has changed since January 16. Senate Data: a. Load either one of the Senate files from the Senate subdirectory in the course directory on the S: drive. b. Convert the affiliation network into a Sociomatrix using the Sociomatrix conversion option. Save it as a Sociomatrix. c. Repeat this operation for two additional Senates. d. Read the files into UCINET (be sure to delete the first row that provides the network identifier—year or senate). e. Recode the files such (using the TRANSFORM RECODE) command such that values going from 0 to 2 get a score of 0 and 3 and above get a score of 1. f. Graph the files using Netdraw. g. Discuss changes in bill co sponsorship patterns over time. h. Repeat steps a-g above using the Standardized Euclidean Distance conversion. In repeating stage e use the 0.5 cutoff point for coding 1’s in the recoded matrix. IGO Data. a. Load either the igoaffil.csv file from the IGO directory or three separate IGO files from the IGO affil (CSV files) subdirectory. If you choose the latter option, be sure to insert a column with the year number (same year number for all rows) to the left of the first column. Convert the affiliation network into a Sociomatrix using the Sociomatrix conversion option. Save it as a Sociomatrix. b. Repeat this operation for two additional years. c. Read the files into UCINET one at a time (be sure to delete the first row that provides the network identifier—year or senate). d. Graph the files using Netdraw. e. Discuss changes in joint IGO membership patterns over time. f. Repeat steps a-g above using the Standardized Euclidean Distance conversion. In repeating stage e use the 0.8 cutoff point for coding 1’s in the recoded matrix.
