From reviews of the first edition:-".... quality and qulaity of illustrations is noteworthy... a comprehensive and thought provoking summary of stepping motor technology. Times Higher Education Supplement.A general textbook on the use of stepping motors ... a comprehensive guide to the subject. Electronics and Power.Whenever repeated stop-start or incremental controlled motions are encountered, there are apllications for stepping motors. Their basic design and constructure make them enimently suitable for digital (microprocessor) control and they are consequently found in computer hardware- disk drives, printers, etc, in clocks, in numerically controlled machine books, and in domestic appliances.In this successful textbook, the authors take a practical approach to stepping motors, using many informative diagrams to explain their working principles, construction details, electronic controls, applications, and methods of maufacutre.Land of the Cosmic Race is a richly-detailed ethnographic account of the powerful role that race and color play in organizing the lives and thoughts of ordinary Mexicans. It presents a previously untold story of how individuals in contemporary urban Mexico construct their identities, attitudes, and practices in the context of a dominant national belief system. The book centers around Mexicans' engagement with three racialized pillars of Mexican nationalideology - the promotion of race mixture, the assertion of an absence of racism in the country, and the marginalization of blackness in Mexico. The subjects of this book are mestizos - the mixed-race people of Mexico who are of Indigenous, African, and European ancestry and the intended consumers of this national ideology. Land of the Cosmic Race illustrates how Mexican mestizos navigate the sea of contradictions that arise when their everyday lived experiences conflict with the national stance and how they manage these paradoxes in a way that upholds, protects, and reproduces the national ideology. Drawingon a year of participant observation, over 110 interviews, and focus-groups from Veracruz, Mexico, Christina A. Sue offers rich insight into the relationship between race-based national ideology and the attitudes and behaviors of mixed-race Mexicans. Most importantly, she theorizes as to why elite-based ideology not onlysurvives but actually thrives within the popular understandings and discourse of those over whom it is designed to govern.
