Sažetak	Gould-Fernandez brokerage analysis classifies the intermediary positions actors occupy in a network. For every two-path in which an actor v sits between a source i and a target j, the analysis labels v's role according to the group memberships of the three actors, yielding five distinct brokerage types — coordinator, itinerant broker (consultant), gatekeeper, representative, and liaison. Counting how often each actor plays each role reveals who mediates within groups, who controls access across group boundaries, and who bridges otherwise separate communities.	Blockmodeling is a family of methods that simplify a social network by partitioning its actors into positions — groups of actors who are equivalent in their pattern of ties — and summarizing the relations between positions as a compact image, or reduced role structure. Introduced by Harrison White, Scott Boorman, and Ronald Breiger in 1976, it shifts attention from individuals to the structural roles they occupy.
