Margiotta, “Civilian Control and the Mexican Military: Changing Patterns of Political Influence,” in Civilian Control of the Military: Theories and Cases from Developing Countries, edited by Claude E. Welch, Jr. (Albany, N.Y.: State University of New York Press, 1976); and David Ronfeldt, “The Mexican Army and Political Order since 1940,” in Armies and Politics in Latin America, edited by Abraham F. Lowenthal (New York: Holmes and Meier, 1976).
