This paper discusses the reform of the Federal employee retirement system in the U.S. The paper argues that this reform experience may provide interesting insights for the reform of public-sector pensions in Brazil and other developing countries.
We explore the use of proper priors for variance parameters of certain sparse Bayesian regression models. This leads to a connection between sparse Bayesian learning (SBL) models (Tipping, 2001) and the recently proposed Bayesian Lasso (Park and Casella, 2008). We outline simple modifications of existing algorithms to solve this new variant which essentially uses type-II maximum likelihood to fit the Bayesian Lasso model. We also propose an Elastic-net (Zou and Hastie, 2005) heuristic to help with modeling correlated inputs. Experimental results show the proposals to compare favorably to both the Lasso and traditional and more recent sparse Bayesian algorithms.
Information technology (IT) enables food retailers to respond more effectively to fluctuating consumer demand caused by changing demographics and taste. One particularly important result is to reduce inventory costs dramatically. Such progress motivates retailers and suppliers to form strategic alliances in order to realize more profit from introducing new IT systems. Together with the introduction of such IT systems, however, it is also critical to establish a well-functioning delivery system between retail stores and suppliers is also critical if both retailers and suppliers are to actually achieve lower inventories. Such a delivery system needs to be very well managed in terms of ordering and stocking all merchandise on an item by item basis. In other words, the IT system by itself will not return real benefits to both parties witho...
Understanding changes in ocean circulation during the last deglaciation is crucial to unraveling the dynamics of glacial-interglacial and millennial climate shifts. We used neodymium isotope measurements on postdepositional iron-manganese oxide coatings precipitated on planktonic foraminifera to reconstruct changes in the bottom water source of the deep western North Atlantic at the Bermuda Rise. Comparison of our deep water source record with overturning strength proxies shows that both the deep water mass source and the overturning rate shifted rapidly and synchronously during the last deglacial transition. In contrast, any freshwater perturbation caused by Heinrich event 1 could have only affected shallow overturning. These findings show how changes in upper-ocean overturning associated with millennial-scale events differ from those...
Damascus at Night: A Ballet for Orchestra by Anthony J. Elia, Composed September 3-28, 2013; 573 pages, Performance Time: 1:17:14 (without breaks)/1:30:00 (with breaks) =============================================== “Damascus at Night” is a 21-movement ballet for orchestra about the elements of human suffering, uncertainty, and the search for hope in the Syrian Civil War (2013). The ballet addresses the human side of the conflict, portraying moments as far reaching as life around a kitchen table, a puppet theater, a church, a refugee camp, and an “old folks” home. The ~573-page work was written over twenty-five days in September 2013, and was composed for ballet companies to adapt freely and creatively at their discretion. Performance times will vary, depending on chosen tempi, but the recommended length would likely run between 1:17:...
This paper examines access to external financing in the privatization context and provides new evidence on the effects of financing constraints on performance and investment. Ownership reforms increase firms’ reliance on external financing. Empirically, performance and investment changes around ownership reforms are increasing in country-level measures of access to credit. The presence of a severe prior public financing constraint contributes to stronger investment growth after privatization. Privatized enterprises do not outperform publicly owned industries, all else given. Our analyses rely on new international sector- and firm-level data and correct for potential endogeneity of ownership changes.
The authors provide the articulation of the ethical argument for the role of vulnerability researchers and security practitioners. They argue that, provided that these researchers don't themselves engage in conduct that causes harm, their conduct doesn't necessarily run afoul of ethical and legal considerations. Furthermore, creating effective defenses against cyberthreats requires vulnerability researchers and practitioners to master techniques such as network recognizance, reverse engineering, penetration testing, and vulnerability exploitation. Although some consider research employing such techniques unequivocally unethical and possibly illegal, a deep understanding in these areas is pivotal to understanding and mitigating the escalating cyberthreat. Using the case study of recent work done at Columbia University, the authors advoc...
I am an old crippled white guy in love with a young Japanese-Canadian-American woman, and we talk about race and age and polio and disability, but race and disability do not consume our lives. Most of our lives are taken up with love and children and mortality and politics and literature—just like anyone else.My plays don't take race and disability as their subject matter. Other plays do, and I think that is a good and necessary thing, and I hope many plays will be written and produced that deal directly with these issues.But I want my plays to be the way my own life is: race and disability exist. They are not denied. And, for example, white parents do not have biological black children. But issues of race and disability do not always consume the lives of people of color or people in wheel chairs. In my plays, as in life itself, the fe...
There is no such thing as an original play.

None of the classical Greek plays were original: they were all based on earlier plays or poems or myths. And none of Shakespeare's plays are original: they are all taken from earlier work. As You Like It is taken from a novel by Thomas Lodge published just 10 years before Shakespeare put on his play without attribution or acknowledgment. Chunks of Antony and Cleopatra are taken verbatim, and, to be sure, without apology, from a contemporary translation of Plutarch's Lives. Brecht's Caucasian Chalk Circle is taken from a play by Klabund, on which Brecht served as dramaturg in 1926; and Klabund had taken his play from an early Chinese play.

Sometimes playwrights steal stories and conversations and dreams and intimate revelations from their friends and lovers and call this original...
