OFC/NFOEC 2011 Program Archive
OFC/NFOEC 2011 Archive Technical Conference: March 6-10, 2011 Exposition: March 8-10, 2011 Los Angeles Convention Center, Los Angeles, CA, USA At OFC/NFOEC 2011, the optical communications industry was buzzing with the sounds of a larger exhibit hall, expanded programming, product innovations, cutting-edge research presentations, and increased attendance March 6 - 10 in Los Angeles. The exhibit hall grew by 20 percent over last year, featuring new programming for service providers and data center operators, and more exhibitors filling a larger space, alongside its core show floor programs and activities. The more than 500 companies in the exhibition hall showcased innovations in areas such as 100G, tunable XFPs, metro networking, Photonic Integrated Circuits, and more. On hand to demonstrate where the industry is headed were network and test equipment vendors, sub-system and component manufacturers, as well as software, fiber cable and specialty fiber manufacturers. Service providers and enterprises were there to get the latest information on building or upgrading networks or datacenters. OFC/NFOEC also featured expanded program offerings in the areas of high-speed data communications, optical internetworking, wireless backhaul and supercomputing for its 2011 conference and exhibition. This new content and more was featured in standing-room only programs such as the Optical Business Forum, Ethernet Alliance Program, Optical Internetworking Forum Program, Green Touch Panel Session, a special symposium on Meeting the Computercom Challenge and more. Flagship programs Market Watch and the Service Provider Summit also featured topics on data centers, wireless, 100G, and optical networking. Hundreds of educational workshops, short courses, tutorial sessions and invited talks at OFC/NFOEC covered hot topics such as datacom, FTTx/in-home, wireless backhaul, next generation data transfer technology, 100G, coherent, and photonic integration. -

It was an honor to know them and a privilege to be taught by them. ACKNOWLEDGEMENTS This dissertation has been a long time in the making and it would not have been possible without the help of many people around the world. I am particularly indebted to Professor William Roger Louis, who has been incredibly patient with me over the eight years it has taken to get this written. Regular work weeks of 60+ hours for years on end made finding the time to advance this project much more difficult than I anticipated. Professor Louis never lost faith that I would complete this project and his encouragement inspired me to keep going even when other commitments made completion look well-nigh impossible. -

THE ANATOMY OF BANKRUPTCY UCS The Anatomy of Bankruptcy Robin Murray SPOKESMAN BOOKS 1972 Printed by Tbe Russell Press Limited Set in Baskerville (IBM 72) Published by The Bertrand Russell Peace Foundation Limited Bertrand Russell House, Gamble Street, Forest Road West, Nottingham NG7 4ET Copyright@ The Spokesman 1972 Acknowledgements This text was originally submitted as a paper in evidence on behalf of The Spokesman to the Comm- ittee of Inyuiry into the Proposed Run Down of Upper Clyde Shipbuilders commissioned by the Scottish Trades Union Congress, under the chair- manship of Professor Raymond Illsley. The author would like to thank the following for their helpful comments: Michael Barratt Brown, Ken Coates, Ken Fleet, Andrew Glyn, John Pollert, Tony Topham, David Yaffe and Sigurd Zienau. Contents Chapter I Page ! Bankruptcy and 'Inefficiency' 9 l Chapter I1 1 Effects of the Bankruptcy Chapter 111 'Efficiency' and the shipbuilding Industry 61 Chapter IV Workers' Control versus Market Rationality Introduction In attempting to measure the likely consequences of the run down of Upper Clyde Shipbuilders detailed assessmentslhave been made of the social costs and benefits whicfi do not enter into the cal- culations of a private company (external economies and diseconomies, employment and other welfare considerations), and which should be taken into account when considering the actions of any private concern from a social point of view. Yet apart from these external factars, does the fact that UCS went bankrupt reflect the fact that it was ineffi- cient within its own private terms? The traditional view is that any individual capita- list in pursuing his own good is also pursuing the good of society. -
