This paper investigates whether risk-related disclosure, which includes aggregate risk disclosure and its tone, including upside downside disclosures, is value relevant for investors in the UK market. Based on 1941 firm-year observations nonfinancial firms listed FTSE All-Share, we employ fixed-effect estimations find that relevance of information not statistically observable unless a distincti...

Abstract A towing tank is utilized to investigate the flow field around a two-dimensional submerged foil model operating near free surface. Free surface effects are analyzed for steady and unsteady velocity. The model’s submergence depth angle of attack varied. Tests conducted facing upside-up upside-down. deflection recorded experimental results validate an analytic that deployed predict wake ...

The technique of Dynamic Programming (DP) could be described “recursion turned upside-down”. However, it is not usually used as an alternative to recursion. Rather, dynamic programming is used (if possible) for cases when a recurrence for an algorithmic problem will not run in polynomial-time if it is implemented recursively. So in fact Dynamic Programming is a morepowerful technique than basic...

chemical foundation of these disciplines. The author avoids the principal pedagogic sin of talking, in an equal tone of voice, of subjects of widely varying importance. This is clearly one man's account, but it is balanced, reasonable, and so lucid that one can read it with pleasure. It is a pity that the production of the book is not of as high a standard as its contents. In the review copy a ...

We study the decoherence induced by the environment over a composite quantum system, comprising two coupled subsystems A and B, which may be a harmonic or an upside-down oscillators. We analyze the case in which the B-subsystem is in direct interaction with a thermal bath, while the other remains isolated from the huge reservoir. We compare the results concerning the decoherence suffered by the...
