Zhrnutie	Structural holes analysis, developed by Ronald Burt, measures the brokerage opportunities available to an actor by examining the gaps — structural holes — between their otherwise disconnected contacts. An actor whose contacts do not know each other bridges non-redundant sources of information and control and is said to be rich in structural holes; an actor whose contacts are all interconnected is constrained. The core measures — network constraint, effective size, and efficiency — quantify how much advantage an ego's network structure confers.	Core/periphery analysis partitions a network into a densely interconnected core of actors and a sparse periphery whose members connect to the core but not to one another. Formalized by Borgatti and Everett, the method fits the observed adjacency matrix to an idealized block pattern — a fully connected core block, an empty periphery block, and core–periphery blocks of intermediate density — to test whether and how strongly a network exhibits this canonical mesoscale structure.
