"The United States Code is the official codification of the general and permanent laws of the United States of America. The Code was first published in 1926, and a new edition of the code has been published every six years since 1934. The 2012 edition of the Code incorporates laws enacted through the One Hundred Twelfth Congress, Second Session, the last of which was signed by the President on January 15, 2013. It does not include laws of the One Hundred Thirteenth Congress, First Session, enacted between January 2, 2013, the date it convened, and January 15, 2013. By statutory authority this edition may be cited "U.S.C. 2012 ed." As adopted in 1926, the Code established prima facie the general and permanent laws of the United States. The underlying statutes reprinted in the Code remained in effect and controlled over the Code in case of any discrepancy. In 1947, Congress began enacting individual titles of the Code into positive law. When a title is enacted into positive law, the underlying statutes are repealed and the title then becomes legal evidence of the law. Currently, 26 of the 51 titles in the Code have been so enacted. These are identified in the table of titles near the beginning of each volume. The Law Revision Counsel of the House of Representatives continues to prepare legislation pursuant to 2 U.S.C. 285b to enact the remainder of the Code, on a title-by-title basis, into positive law. The 2012 edition of the Code was prepared and published under the supervision of Ralph V. Seep, Law Revision Counsel. Grateful acknowledgment is made of the contributions by all who helped in this work, particularly the staffs of the Office of the Law Revision Counsel and the Government Printing Office"--Preface.

This volume stems from the efforts of scholars who seek to understand the social dynamics of large technical systems. The purpose is to develop concepts and empirical knowledge concerning the dynamics of such systems, with particular emphasis on the processes ofcontrol and/or management in a variety of national settings, and to improve the basis of public policy so that future developments might be less distressing in consequence and more shaped to the desires of their "host" societies. One vehicle for this enterprise is a series of international conferences on the Evolution andDynamics ofLarge Technical Systems (LTSs). This series was instituted to encourage the coalescence of the multidisciplinary group of scholars who are actively engaging in the empirical study of these phenomena. Their disciplines span history, sociology, political science, and economics studies. They come Australia, France, the Netherlands, Norway, Sweden, the United Kingdom, the United States, and West Germany. And they possess strong backgrounds in the empirical study of specific technical areas and a taste for conceptual and theoretical integration.
