Political Opportunity Structure Analysis

Political Opportunity Structure
Political opportunity structure majorly explains linkage between political environment and social movement. Meanwhile, POS admits influences of resources and grievance. The major argument of POS is political structure decides social movements' fates. McAdam concluded four major dimensions of POS theory: openness of institutional structure, division and alliance from elite groups and state power for repression. (1996, p27) For each stage, author will briefly evaluate the POS separately. For this analysis, the historical backgrounds and divisions are extremely important. In this section, author attempts to connect opportunity structure and development of movement.
At preface stage, as post-colonial countries,

(Snow & Benford, 1986,p464) More specifically, how social movement organizations mobilize and recruit members.

For money, labour and facilitates, more details are needed. For POS, in spite of possible distortion by author's division, it supports growth of indígenas movements. For framing, except diagnostic framing, prognostic and motivational framings are influenced by lack of details. However, framing analysis did provide more detailed strategies of how indígenas movement
