Over the 1980s and 1990s, most Latin American countries witnessed a retrenchment of the public sector away from infrastructure provision and an opening up of infrastructure activities to the private sector. This book analyzes the consequences of these policy changes from two perspectives. First, it reviews in a comparative framework the major trends in infrastructure provision in Latin America over the last two decades. Second, it evaluates the implication of these trends for economic growth and public deficits in the region. The book shows that in most countries private participation did not fully offset the public sector retreat. The result was a slowdown in infrastructure accumulation, which entailed a significant growth cost and weakened the intended impact of the infrastructure spending cuts on public sector insolvency.

This authored monograph presents a study on fundamental limits and robustness of stability and stabilization of time-delay systems, with an emphasis on time-varying delay, robust stabilization, and newly emerged areas such as networked control and multi-agent systems. The authors systematically develop an operator-theoretic approach that departs from both the traditional algebraic approach and the currently pervasive LMI solution methods. This approach is built on the classical small-gain theorem, which enables the author to draw upon powerful tools and techniques from robust control theory. The book contains motivating examples and presents mathematical key facts that are required in the subsequent sections. The target audience primarily comprises researchers and professionals in the field of control theory, but the book may also be beneficial for graduate students alike.

Examines the factors which limit human economic and population growth and outlines the steps necessary for achieving a balance between population and production. Bibliogs

The development of polymers as an important class of material was inhibited at the first by the premature failure of these versatile compounds in many applications. The deterioration of important properties of both natural and synthetic polymers is the result of irreversible changes in composition and structure of polymers molecules. As a result of these reactions, mechanical, electrical and/or aesthetic properties are degraded beyond acceptable limits. It is now generally recognized that stabilization against degradation is necessary if the useful life of polymers is to be extended sufficiently to meet design requirements for long-term applications. Polymers degrade by a wide variety of mechanisms, several of which affect all polymers through to varying degree. This monograph will concentrate on those degradation mechanisms which result from reactions of polymers with oxygen in its various forms and which are accelerated by heat and/or radiation. Those stabilization mechanisms are discussed which are based on an understanding of degradation reaction mechanisms that are reasonably well established. The stabilization of polymers is still undergoing a transition from an art to a science as mechanisms of degradation become more fully developed. A scientific approach to stabilization can only be approached when there is an understanding of the reactions that lead to degradation. Stabilization against biodegradation and burning will not be discussed since there is not a clear understanding of how polymers degrade under these conditions.

U.S. experiences in Iraq and Afghanistan have demonstrated that improving U.S. capacity for stabilization and reconstruction operations is critical to national security. To help craft a way ahead, the authors provide an overview of the requirements posed by stabilization and reconstruction operations and recommend ways to improve U.S. capacity to meet these needs.
