We present a new bijective proof of the equality between the number of Littlewood-Richardson fillings of a skew-shape i/n of weight v, and those of the conjugate skew-shape A’/$, of conjugate weight v’. The bijection is defined by means of a unique permutation a,,, associated to the skew-shape i-/p. Our arguments use only well-established properties of Schensted insertion, and make no reference...

We consider the model of Deijfen et al. for the competing growth of two infection types in Rd, based on the Richardson model on Zd. Stochastic ball-shaped infection outbursts transmit the infection type of the center of the ball to all points of the ball that are not yet infected. Relevant parameters of the model are the initial infection configuration, the (typedependent) growth rates and the ...

Stock prices reflect persistence differences across a wide range of accrual types that are categorized in Richardson, Sloan, Soliman, and Tuna (Journal of Accounting and Economics, 2005). Moreover, stock prices reflect short-term persistence differences more strongly than longterm persistence differences. These findings suggest that investors understand persistence of accrual types during the y...

Welcome to the twelfth issue of All-island Obesity News. In this edition I am happy to announce that the Forum will host a workshop on June 8 2011 entitled „Weigh to Men‟s Health‟ supported by safefood and the Ulster Cancer Foundation. This workshop will highlight that excess weight is a health issue that most men are not aware of. Presentations will discuss best practice in how to target men p...

Historical ship drifts from the tropical Atlantic Ocean are compared with surface currents from a general circulation model forced with monthly mean climatological winds. The model accurately reproduces the spatial structure of the currents and its time dependence, which varies considerably from the eastern side of the basin, where a semiannual harmonic is prominent, to the western side, where ...

In this study, the authors explore how vertical-mixing parameterizations influence the structure of zonal currents in the eastern equatorial Pacific using an isopycnal ocean model that contains an explicit surface mixed layer. The mixing parameterizations considered are the schemes that depend on the Richardson number (Ri). One of the schemes (the Step scheme) consists of high (nc) and low (nb)...

The paper presents and formalises an approach to the evolution of the organisation of industry which starts from multi-activity firms, and which relates to economists like Young, Stigler, and Richardson. To capture the open-ended process of disintegration of industry, the paper operates with decomposable tasks and gives an account of the vertical and horizontal structure of production by means ...
