Discrepancies between assumed dynamical models and observations are often handled by making further probabiIistic assumptions, a tactic which has both strengths and weaknesses. A re-examination of filtering and smoothing is conducted, and an alternative multicriteria approach, which is probability free, is advanced. This approach involves vector minimization as a key ingredient, and it speciali...

Encouraging people to consider multiple alternatives appears to be a useful debiasing technique for reducing many biases (explanation, hindsight, and overconfidence), if the generation of alternatives is experienced as easy. The present research tests whether these alternative generation procedures induce a mental simulation mind-set (cf. Galinsky & Moskowitz, 2000), such that debiasing in one ...

The incidence of developmental orthopedic disease on a commercial Thoroughbred farm was studied over a four year period. A total of 271 foals were monitored. DOD was diagnosed in 10% of the foals. Fetlock OCDs tended to occur before 180 days of age while hock, shoulder and stifle OCDs occurred around 300-350 days of age. Foals that developed hock and stifle OCDs as yearlings tended to be large ...

Lameness causes major financial losses and welfare problems in dairy herds. Prevention of foot lesions may suffice in the majority of lameness cases. The objectives of this longitudinal study were to describe the dynamics and associations between abnormal hind leg conformation, asymmetric claws, lameness, and foot lesions in 122 Danish Holstein heifers from an average of 41 d before first calvi...

The DARPA Internet uses the Domain Name Sys tem DNS a distributed database to map host names to network addresses and vice versa Using a vulnerability rst noticed by P V Mockapetris we demonstrate how the DNS can be abused to sub vert system security We also show what tools are useful to the attacker Possible defenses against this attack including one implemented by Berkeley in re sponse to our...

We replicate Moskowitz and Grinblatt’s (1999) findings on industry momentum using data for US large cap stocks between 1998 and 2007. Moskowitz and Grinblatt find that industry momentum strategies appear to be highly profitable. Moskowitz and Grinblatt also demonstrate that individual stock momentum strategies, which buy past winning stocks and sell past losing stocks, are less profitable after...
