Résumé	World-systems analysis is a historical-structural framework, founded by Immanuel Wallerstein in The Modern World-System (1974) and codified in his 2004 introduction, that takes as its unit of analysis not the nation-state but a single, integrated capitalist world-economy that has expanded since the long sixteenth century to encompass the globe. Within this world-economy a single axial division of labor binds together a hierarchy of zones — core, semiperiphery, and periphery — through which surplus flows unequally from peripheral to core regions. States, classes, and firms are understood by their position in this structure rather than as self-contained societies, and the system is read over the longue duree, attentive to long cycles of accumulation and to the rise and decline of successive hegemonic powers.	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.
