Using a representative agent model in which the investor is averse to ambiguity (Knightian uncertainty) and sees an ambiguous piece of news about the fundamental value of a risky asset, I show a number of predictions for the dynamics of stocks around news: Stocks respond more strongly to bad news than to good news, respond positively to neutral news, and increase on average through news. In tim...
One of the earliest and most influential papers applying Darwinian theory to human cultural evolution was Donald T. Campbell’s paper “Variation and Selective Retention in Sociocultural Systems.” Campbell’s programmatic essay appeared as a chapter in a book entitled Social Change in Developing Areas (Barringer et al., 1965). It sketched a very ambitious project to apply Darwinian principles to t...
In this article, we study parameter-dependent systems of reaction-diffusion equations on the sphere, which are equivariant under the group SO(3) of all rigid rotations on a sphere. Two main types of spatial-temporal patterns that can appear in such systems are rotating waves (equilibrium in a co-rotating frame) and modulated rotating waves (periodic solution in a corotating frame). The transiti...
This paper deals with an interactive storytelling of game, based on Campbells heroes journey. It begins by introducing Campbell analysis and then presents how this model has been transformed in order to support for interactive storytelling. Then, it shows how this model can be used for educational games. It finishes by an experimentation of an implementation of this interactive storytelling in ...
circled, enframed,” wrote 20th-century American mythologist and lecturer Joseph Campbell. This month’s cover art, A Timeless Symbiosis, uses the motif of circles to connect animals and humans. Bindu Viswanathan, the artist who created the painting, is also a lecturer and biostatistician at the University of Texas, Austin. Many of her paintings inspire viewers to think about the fuller connectio...

Using a number of short-term maturities and monthly data, 1984-1997, we provide a number of tests of the expectations hypothesis (EH) of the term structure. The paper draws on cointegration techniques and the methodological approach of Campbell and Shiller (1987,1991). On balance our results lend support to the EH and are broadly consistent with recent findings for the UK, but are in sharp cont...
Performance and reliability of any rotating machine can be studied by proper dynamic analysis of the machine. In this regard, this paper presents the method to study the dynamic response of the shaft of a Pelton turbine due to the impact of water jet. Equations of motion for the bending vibration of Pelton turbine assembly, in two transverse directions, is developed by using Lagrange equation o...
Book Reviews: "Musical Instruments: History, Technology, and Performance of Instruments of Western Music." by Murray Campbell, Clive Greated and Arnold Myers, and "From Renaissance to Baroque: Change in Instruments and Instrumental Music in the Seventeenth Century: Proceedings of the National Early Music Association Conference held, in association with the Department of Music, University of Yor...
Jet engines need to be certified before going into service, i. e., any dangerous vibration has to be detected. Therefore the eigenmodes, displayed as curves in Campbell diagrams, need to be identified first. At the moment this is done manually by engineers. In this paper we introduce a way of automatically detecting eigenmodes in Campbell diagrams by introducing an extension of Hough transform.
