Maynard's Revenge: Keynesianism and the Crisis

Google Tech Talk February 16, 2010 ABSTRACT Presented by Lance Taylor, Arnhold Professor of International Cooperation and Development at the New School for Social Research. Historically, financial crises have been commonplace. Over the past two decades the sector has staged the 1987 stock market crash, the Mexican crisis, the Asian crisis, Enron, the LTCM collapse, the end of the internet bubble, and 2007-09. Why did the latest episode almost derail the world economy? The macroeconomics developed by John Maynard Keynes and his close followers provides the only plausible set of answers, including rising income inequality which spilled over into debt accumulation at the same time as household consumption rose, low real interest rates, massive expansion of financial assets and liabilities as investors borrowed heavily (increased leverage) to buy assets with rising prices, and an ample supply of imports and capital inflows from the rest of the world. In an accommodating political economic environment these factors linked the real and financial sides of the economy to create the crisis.

The Query Complexity of Estimating Weighted Averages

Google Tech Talk February 4, 2010 ABSTRACT Presented by Tony Wirth. The query complexity of estimating the mean of some [0, 1] variables is well known to the theory community. Inspired by some work by Carterette et al. [SIGIR 2006, pp 26875] on evaluating retrieval systems, and by Moffat and Zobel's new proposal for such evaluation [under review], we decided to examine the query complexity of weighted average calculation. In general, the problem requires the same number of queries as estimating the mean, as the latter is a special case. In fact, there is a matching upper bound for the weighted mean. This result remains true for any set of weights that is the normalized prefix of a divergent series. However, if the weights follow a geometric sequence, a much smaller sample is sufficient. Finally, we investigate power-law sequences of weights and show matching lower and upper bounds. This is joint work with Amit Chakrabarti and Venkatesan Guruswami and Andrew Wirth. Tony Wirth joined the faculty of the University of Melbourne's Computer Science department in 2005. Prior to that, he completed a phd, as a Gordon Wu Fellow, at Princeton University in 2004 on approximation algorithms for clustering problems. Tony completed his undergraduate degree at the University of Melbourne, majoring in statistics. His research interests also include sequence problems in bioinformatics and adaptive sampling.

AFTR the Fire: Carrier Networks and Incremental Deployment of IPv6

AFTR the Fire: Carrier Networks and Incremental Deployment of IPv6

Google Tech Talk January 21, 2010 ABSTRACT Presented by Paul Selkirk, Senior Software Engineer, Internet Systems Consortium. With the impending end of the unallocated pool of ipv4 addresses, the Internet faces a problem: there will be no more unused ipv4 space to assign as networks grow, only ipv6. Growth of the network in the future depends on effective deployment of ipv6. But migration of the existing Internet– end user systems, content sources, enterprise networks, carrier infrastructure– to ipv6 is only happening slowly and irregularly. The technology originally intended to support incremental deployment of ipv6, "dual-stack," in which individual end systems are capable of using both ipv4 and ipv6, is not turning out to be practical on the universal scale it was designed for. Several technologies are under development and early deployment to bridge the gap between the ipv4 internet and one that can interoperate between ipv4 and ipv6 in the interim– perhaps lengthy– before ipv6 is "mainstream" globally. This talk will briefly lay out the operational constraints around ipv4/ipv6 co-existence, and then describe isc's implementation of one particular protocol, DS-lite ("Dual-stack lite"). A new product, AFTR (for "Address Family Transition Router"), implements the DS-lite protocol and provides the core of a deployable architecture for ipv4/ipv6 co-existence in carrier networks.

Do My Thoughts Deceive Me? Human Factors and Design

Google Tech Talk December 16, 2009 ABSTRACT Presented by Jason H. Wong. Our brains are not as reliable as we would like to think. Human factors is the science of understanding human cognition and designing systems to work within its limitations. A lot of time and effort has gone into understanding how our brains work (and when they don't). However, we continue to make fundamental design errors that not only go against cognitive science principles but common sense as well. This talk will explore some of the quirkier aspects of our cognition, from visual attention to memory and decision making. There will be copious examples of design gone wrong along with discussions of how to understand how we think and how to avoid making design mistakes in the future. Dr. Jason H. Wong is a Human Factors Scientist with the Naval Undersea Warfare Center (NUWC). He received his Ph.D. in 2009 from George Mason University in Human Factors and Applied Cognition, where he conducted research on visual attention and working memory. He was awarded the Department of Defense SMART Scholarship in 2007. This paved the way for his work at NUWC, where Dr. Wong examines the human-computer interaction aspects of complex systems, develops efficient submariner training methodologies, and creates cognitive models to simulate human performance.

Divide and Conquer: How the Essence of Mindfulness Parallels the Nuts and Bolts of Science

Google Tech Talk January 28, 2010 ABSTRACT Presented by Shinzen Young. The purpose of this talk is threefold: (1) to describe how senior adepts use mindfulness to reduce suffering and gain insight into selfhood and emotions. (2) To point out how the method they use in many ways parallels what scientists do when confronted with a complex and inscrutable system in nature. (3) To discuss how this fundamental parallelism between the two endeavors can become the basis for a productive collaboration in the future. Bio: Shinzen Young became fascinated with Asian culture while a teenager in Los Angeles. Later he enrolled in the Ph.D. program in Buddhist Studies at the University of Wisconsin. Eventually, he went to Asia and did extensive training in each of the three major Buddhist meditative traditions: Vajrayana, Zen, and Vipassana. Upon returning to the United States, his intellectual interests shifted to the burgeoning dialogue between Eastern internal science and Western technological science. In recognition of his original contributions to that dialogue, the Institute of Transpersonal Psychology has awarded him an honorary doctorate. Shinzen's innovative techniques for pain management derived from two sources: The first is his personal experience dealing with discomfort during intense periods of meditation in Asia, and during shamanic ceremonies with tribal cultures. The second is some three decades of experience in coaching people through a wide spectrum of chronic and acute pain challenges. Shinzen leads meditation retreats in the mindfulness tradition throughout North America, and has helped establish several centers and programs.
