This study applies theory from the sociology of professional control to the question, "What factors influence the power, or shifts in power, in the journalist/public relations practitioner dynamic?" A number of predictors of relative control over news coverage are assessed, including resources and proximity of source institutions, pluralism of power in communities, media competition, public ownership, organizational size, and the complexity of coverage areas. Authors found that source resources and dominance of the source in a community play a significant role in shaping control over news information work, as does the degree of complexity of the news topic.
