We explore the consequences of placing the Standard Model gauge fields in the bulk of the recently proposed localized gravity model of Randall and Sundrum. We find that the Kaluza Klein excitations of these fields are necessarily strongly coupled and we demonstrate that current precision electroweak data constrain the lowest states to lie above ' 23 TeV. Taking the weak scale to be ∼ 1 TeV, the...

1. South Africa: Summary of faultlines and action points

We offer a new perspective to the unionised wage effects of unilateral trade liberalisation by considering endogenous domestic market structure. Hence, in contrast to the existing works, which focus on the short-run effects of trade liberalisation on unionised wage, we focus on more long-run effects by considering the effects of trade liberalisation on the domestic market structure. Trade liber...

A new gravity model with the function F (R) = (1/β) arctan (βR− βR) instead of the Ricci scalar in the Einstein–Hilbert action, describing inflation of the Universe, is suggested and analyzed. We obtain constant curvature solutions of the model in the Jordan frame. Performing the conformal transformation of the metric, the potential and the mass of a scalar degree of freedom in the Einstein fra...

The design of new embedded systems is getting more and more complex as more functionality is integrated into these systems. To deal with the design complexity, a predictable design flow is needed. The result should be a system that guarantees that an application can perform its own tasks within strict timing deadlines, independent of other applications running on the system. Synchronous Dataflo...

Economic Incentives and International Trade by Dalia Marin and Monika Schnitzer This paper studies the importance of incentives as a determinant of international trade flows. We argue that barter, countertrade and foreign direct investment can be seen as efficient institutions that mitigate contractual hazards which arise in technology trade, marketing and imperfect capital markets. Paying an i...
