Strategies for Comparative Research in Political Science Theory and Methods B. Guy Peters Series Editors:B.Guy Peters,Jon Pierre and Gerry Stoker Political science today is a dynamic discipline.Its substance,theory and methods have all changed radically in recent decades.It is much expanded in range and scope and in the variety of new perspectives – and new variants of old ones – that it encom- passes.The sheer volume of work being published,and the increasing degree of its specialization,however,make it difficult for political scientists to maintain a clear grasp of the state of debate beyond their own particular subdisciplines. The Political Analysisseries is intended to provide a channel for different parts of the discipline to talk to one another and to new generations of students.Our aim is to publish books that provide introductions to,and exemplars of,the best work in vari- ous areas of the discipline.Written in an accessible style,they provide a ‘launching- pad’ for students and others seeking a clear grasp of the key methodological, theoretical and empirical issues,and the main areas of debate,in the complex and fragmented world of political science. A particular priority is to facilitate intellectual exchange between academic commu- nities in different parts of the world.Although frequently addressing the same intel- lectual issues,research agendas and literatures in North America,Europe and elsewhere have often tended to develop in relative isolation from one another.This series is designed to provide a framework for dialogue and debate which,rather than advocacy of one regional approach or another,is the key to progress. The series reflects our view that the core values of political science should be coher- ent and logically constructed theory,matched by carefully constructed and exhaus- tive empirical investigation.The key challenge is to ensure quality and integrity in what is produced rather than to constrain diversity in methods and approaches.The series is intended as a showcase for the best of political science in all its variety,and demonstrates how nurturing that variety can further improve the discipline.
