Treatment of Border Tax Rebates of Consumption Taxes under the Antidumping Law

This Article describes how Zenith Electronics Corp. v. United States ( Zenith ) made the treatment of export rebates of consumption taxes an issue under the U.S. antidumping law. It explains the position of the Department of Commerce ( Commerce ) that dumping margins should be calculated on a tax net basis (so that they equal the margins that would be found in the absence of taxes), and offers a general criticism of the argument in Zenith

A mathematical formulation for the cell-cycle model in somitogenesis: analysis, parameter constraints and numerical solutions

In this work we present an analysis, supported by numerical simulations, of the formulation of the cell-cycle model for somitogenesis proposed in Collier et al.(J. Theor. Biol. 207 (2000), 305–316). The analysis indicates that by introducing appropriate parameter constraints on model parameters the cell-cycle mechanism can indeed give rise to the periodic pattern of somites observed in normal embryos. The analysis also provides a greater understanding of the signalling process controlling somite formation and allows us to understand which parameters influence somite length

Models for pattern formation in somitogenesis: a marriage of cellular and molecular biology

Somitogenesis, the process by which a bilaterally symmetric pattern of cell aggregations is laid down in a cranio-caudal sequence in early vertebrate development, provides an excellent model study for the coupling of interactions at the molecular and cellular level. Here, we review some of the key experimental results and theoretical models related to this process. We extend a recent chemical pre-pattern model based on the cell cycle Journal of Theoretical Biology 207 (2000) 305-316, by including cell movement and show that the resultant model exhibits the correct spatio-temporal dynamics of cell aggregation. We also postulate a model to account for the recently observed spatio-temporal dynamics at the molecular level

Educational Computing: Some Policy Implications for Administrators

Administrators must also be sensitive to the potential dangers inherent in a thoughtless rush to incorporate computing in schools

Numerical study of the stability of some explicit finite-difference methods for oscillatory advection

This paper is made available with the permission of the Australian Mathematical Society Inc. Copyright © 2005 Australian Mathematical SocietyThe basis for modelling unsteady transport in fluids is the one-dimensional advection equation. When high-order finite-difference methods for constant velocity advection are applied to the variable velocity case, they generally degenerate at least one order. For example, Crowley's formula, which is second order for constant velocity advection, is only first order when used with variable velocities. Modification of Crowley's formula has recently yielded three formulae which are second order in the variable velocity case. Two commonly used local stability analyses have been carried out on these formulae with conflicting results. The resulting stability regions have been studied by means of a series of numerical experiments using an oscillatory advection velocity to determine their applicability in tidal streams.John Noye and David McInerne

Expansion of the investor base for the energy transition

Despite the emergence of the green bond market, the Energy Service Company (ESCO) model and green investment banks, the opportunities which the world’s capital markets present to increase the pool of potential investors and reduce project financing costs for renewable, energy efficient and low carbon assets remain under-exploited. This has been a persistent concern for policy-makers. We review the appeal of this sector to different classes of investor and assess the successes and failures of several innovative products including securitisations, yieldcos, green bonds, green investment banks and crowdfunding. We analyse the experiences with these products and suggest that policy needs to recognise how fiscal initiatives can leverage their inherent appeal
