Policy domain study highlights the effect of location on network influence. Previous research has indicated a relationship between the groups and individuals with the strongest influence reputation and the location of these groups within the environment. In the reading policy environment such groups interact with one another in formal joint projects and informal collaborations. But regardless of the type of interaction, the relationships that these actors form with one another have an effect on their prominence--their centrality and prestige--in the national reading policy domain. Using this rationale, the hypothesis guiding this study is as follows: Central policy actors will be perceived to be more influential than peripheral policy actors in shaping national reading policy. This study of influence and domination employed social network analysis, a methodology commonly used for policy domain study. Social network requires specific procedures (outlined in the study) for data collection, boundary specification, and data measurement. Data included interview transcripts, archival documents, and previous research. Findings show the variety of affiliations among network actors. For example, one clique was composed of five government groups, while another clique comprised a group of policy makers and interest groups. The membership of still another clique illustrates the extent of collaboration between reading content groups, government offices, educational coalitions, and professional organizations.
