Conditioning super-Brownian motion on its boundary statistics, and fragmentation
We condition super-Brownian motion on "boundary statistics" of the exit
measure from a bounded domain . These are random variables defined on
an auxiliary probability space generated by sampling from the exit measure
. Two particular examples are: conditioning on a Poisson random measure
with intensity and conditioning on itself. We find the
conditional laws as -transforms of the original SBM law using Dynkin's
formulation of -harmonic functions. We give explicit expression for the
(extended) -harmonic functions considered. We also obtain explicit
constructions of these conditional laws in terms of branching particle systems.
For example, we give a fragmentation system description of the law of SBM
conditioned on , in terms of a particle system, called the backbone.
Each particle in the backbone is labeled by a measure ,
representing its descendants' total contribution to the exit measure. The
particle's spatial motion is an -transform of Brownian motion, where
depends on . At the particle's death two new particles are born,
and is passed to the newborns by fragmentation.Comment: Published in at http://dx.doi.org/10.1214/12-AOP778 the Annals of

The Chrysler effect : the impact of the Chrysler bailout on borrowing costs
Did the U.S. government's intervention in the Chrysler reorganization overturn bankruptcy law? Critics argue that the government-sponsored reorganization impermissibly elevated claims of the auto union over those of Chrysler's other creditors. If the critics are correct, businesses might suffer an increase in their cost of debt because creditors will perceive a new risk, that organized labor might leap-frog them in bankruptcy. This paper examines the financial market wherethis effect would be most detectible, the market for bonds of highly unionized companies. The authors find no evidence of a negative reaction to the Chrysler bailout by bondholders of unionized firms. They thus reject the notion that investors perceived a distortion of bankruptcy priorities. To the contrary, bondholders of unionized firms reacted positively to the Chrysler bailout. This evidence suggests that bondholders interpreted the Chrysler bailout as a signal that the government will stand behind unionized firms. The results are consistent with the notion that too-big-to-fail government policies generate moral hazard in the credit markets.Debt Markets,Bankruptcy and Resolution of Financial Distress,Emerging Markets,Deposit Insurance,Access to Finance
A dıscourse analysis inıtıatıve: The story of Soldıer and Cındırella
Söylem analizine girişilen Asker ve Sindirella hikayesi bir İsrail askeriyle Filistinli küçük bir kız arasındaki insani etkileşimi anlatmaktadır. Bu etkileşim anlatılırken kullanılan dil, oldukça sembolik ve anlam yüklüdür. Anlatı, taraflardan birinin –İsrail- medya tarafından yanlış gösterildiği iddiası üzerine kuruludur. Bu çalışmada, incelenen hikayedeki sembolik dil deşilmeye ve yazarın veya yazarların satır aralarına sakladıkları mesajlar okunmaya çalışılmıştır. Yazarın mesajını, aynı kavramların benzer ifadelerle sık sık verilmesi esasına göre benimsetmeye çalıştığı yani tekrarlı baskılama tekniğini kullandığı iddia edilmektedirThe story of Soldier and Cinderella, analysed text, tells an humanistic interaction between an Israeli soldier and a little Palestinian girl. The language which used to explain this interaction is quite symbolic and meaningful. The narrative is based on the claim of misrepresentation the one of –Israel- two sides. In this study, we endeavor to decrypt the symbolic language used in the story and to read the hidden messages in the line breaks. We claim that the author tries to adopt his message, on the basis of repeating same concepts with the similar expressions, by the technique of repeatingly suppressio
