我们调查了第 101 届至第 108 届国会期间美国众议院的委员会和小组委员会的分配网络，这些委员会通过“联锁”或共同成员资格连接起来。我们使用多种方法检查这些网络中的社区结构，揭示了某些委员会之间的紧密联系以及整个众议院的内在等级结构。我们确定了 1994 年选举带来的结构性变化，包括额外的层级和更高的模块化，共和党在 40 多年来首次在众议院赢得了多数地位。我们还将网络方法与使用奇异值分解的唱名投票分析相结合，以揭示众议院委员会的政治结构和组织结构之间的相关性。 (c) 2007 Elsevier B.V. 保留所有权利。
We investigate the networks of committee and subcommittee assignments in the United States House of Representatives from the 101st-108th Congresses, with the committees connected by "interlocks" or common membership. We examine the community structure in these networks using several methods, revealing strong links between certain committees as well as an intrinsic hierarchical structure in the House as a whole. We identify structural changes, including additional hierarchical levels and higher modularity, resulting from the 1994 election, in which the Republican party earned majority status in the House for the first time in more than 40 years. We also combine our network approach with the analysis of roll call votes using singular value decomposition to uncover correlations between the political and organizational structure of House committees.
