Agricultural Trade Reform and Industry Adjustment in Indonesia

This paper presents a component of a project on industry adjustment to agricultural trade reform in selected developing countries. The aim of the project is to examine the issues affecting the development of industry adjustment policies to manage the impact of trade reform. It will evaluate specific developing country examples of industries that are likely to face significant adjustment pressures from trade policy reform. The study is focused on industry specific policy responses for two reasons. First, many LDC's are concerned about the consequences of future WTO reforms for adjustment in 'sensitive' industries. Governments in developing countries have received advice and assistance on how to comply with the requirements of their WTO commitments from the Uruguay Round of trade negotiations. However, very little attention has been devoted to the domestic effects of trade reform. Second, the implementation of international trade commitments is likely to lead to industry requests for assistance. Adjustment policies used by developed countries may not be directly applicable to LDC situations. Differences in structural characteristics, institutional arrangements and the level of industry development require an investigation of the issues affecting adjustment in developing countries.International Relations/Trade,

Nonlinear Attitude Control of Planar Structures in Space Using Only Internal Controls

An attitude control strategy for maneuvers of an interconnection of planar bodies in space is developed. It is assumed that there are no exogeneous torques and that torques generated by joint motors are used as means of control so that the total angular momentum of the multibody system is a constant, assumed to be zero. The control strategy utilizes the nonintegrability of the expression for the angular momentum. Large angle maneuvers can be designed to achieve an arbitrary reorientation of the multibody system with respect to an inertial frame. The theoretical background for carrying out the required maneuvers is summarized

Agricultural Policy Reform and Industry Adjustment in Australia and New Zealand

Some sectors of Australian and New Zealand farming have been heavily assisted in the past. New Zealand underwent an economy-wide deregulation in the mid-to-late 980s that included abrupt removal of practically all agricultural assistance. Policy reform in Australia has been more gradual and is industry focused, but in some cases substantial industry assistance has been withdrawn. Deregulation of the Australian dairy industry, and that of the sheep and beef sector in New Zealand, are discussed as case studies of these deregulations. Conclusions are drawn from these experiences, a major one being that previously-assisted farmers can successfully make the transition to market-driven agriculture.agricultural adjustment, policy reform, Australia, New Zealand, Agricultural and Food Policy,

Computational Dynamics of a 3D Elastic String Pendulum Attached to a Rigid Body and an Inertially Fixed Reel Mechanism

A high fidelity model is developed for an elastic string pendulum, one end of which is attached to a rigid body while the other end is attached to an inertially fixed reel mechanism which allows the unstretched length of the string to be dynamically varied. The string is assumed to have distributed mass and elasticity that permits axial deformations. The rigid body is attached to the string at an arbitrary point, and the resulting string pendulum system exhibits nontrivial coupling between the elastic wave propagation in the string and the rigid body dynamics. Variational methods are used to develop coupled ordinary and partial differential equations of motion. Computational methods, referred to as Lie group variational integrators, are then developed, based on a finite element approximation and the use of variational methods in a discrete-time setting to obtain discrete-time equations of motion. This approach preserves the geometry of the configurations, and leads to accurate and efficient algorithms that have guaranteed accuracy properties that make them suitable for many dynamic simulations, especially over long simulation times. Numerical results are presented for typical examples involving a constant length string, string deployment, and string retrieval. These demonstrate the complicated dynamics that arise in a string pendulum from the interaction of the rigid body motion, elastic wave dynamics in the string, and the disturbances introduced by the reeling mechanism. Such interactions are dynamically important in many engineering problems, but tend be obscured in lower fidelity models.Comment: 17 pages, 14 figure
