A cleaner production demonstration study was developed in 1998 for the chemical industry by the Mexican Center for Cleaner Production with the support of the United States Agency for International Development (USAID). The project's objective was to develop cleaner production assessments for chemical plants by identifying and evaluating process and energy cleaner production opportunities for technical feasibility, economic benefit and environmental impact. Four plants in the chemical industry groups of inorganic and organic chemicals and plastic materials and synthetic resins were involved. The main results are: (1) a reduction of solid toxic residues in the organic chemicals plant of 3,474 kg/year with after-tax savings of US$ 318,304/year; (2) an increase in plant capacity of 56%, and 10% reduction in VOCs emissions in the plasticizers and epoxidated soybean oil plant with after-tax savings of US$ 2,356,000/year; (3) a reduction of 31,150 kg/year of ethylene oxide emissions with after-tax savings of US$ 17,750/year in the polyethylene glycol plant and (4) a reduction of CO2 emissions of 9.21% with after-tax savings of US$ 44,281/year in the inorganic chemicals plant. The principal areas for improvement in the chemical industry are process control and instrumentation, process design, maintenance programs and providing adequate utilities for the plants.

Foreign aid has been the subject of much examination and research ever since it entered the economic armamentarium approximately 45 years ago. This was the time when the Second World War had successfully ended for the Allies in the defeat of Germany and Japan. However, a new enemy, the Soviet Union, had materialized at the end of the conflict. To counter the threat from the East, the United States undertook the implementation of the Marshal Plan, which was extremely successful in rebuilding and revitalizing a shattered Western Europe. Aid had made its impact. The book under review is by three well-known economists and is the outcome of a study sponsored by the Department of State and the United States Agency for International Development. The major objective of this study was to evaluate the impact of assistance, i.e., aid, on economic development. This evaluation however, was to be based on the existing literature on the subject. The book has five major parts: Part One deals with development thought and development assistance; Part Two looks at the relationship between donors and recipients; Part Three evaluates the use of aid by sector; Part Four presents country case-studies; and Part Five synthesizes the lessons from development assistance. Part One of the book is very informative in that it summarises very concisely the theoretical underpinnings of the aid process. In the beginning, aid was thought to be the answer to underdevelopment which could be achieved by a transfer of capital from the rich to the poor. This approach, however, did not succeed as it was simplistic. Capital transfers were not sufficient in themselves to bring about development, as research in this area came to reveal. The development process is a complicated one, with inputs from all sectors of the economy. Thus, it came to be recognized that factors such as low literacy rates, poor health facilities, and lack of social infrastructure are also responsible for economic backwardness. Part One of the book, therefore, sums up appropriately the various trends in development thought. This is important because the book deals primarily with the issue of the effectiveness of aid as a catalyst to further economic development.

This paper presents a set of best practices and lessons learned from a set of 93 impact evaluations conducted on community-level, small grants activities implemented between March 2003 and September 2007 by the Sri Lanka country programme of the Office of Transition Initiatives (OTI) of the United States Agency for International Development (USAID). It analyses the change theories that guided programme development and common trends in impact which emerged, and discusses ways in which programme staff can improve project impact. It provides a working definition of ‘process’, a key element of OTI's approach and a key concept used by facilitators to understand the work they do with groups and communities. It also delineates a general typology of peacebuilding projects likely to emerge in the community setting. Finally, it formulates a postulate for predicting and observing generic programme impact based upon the relative richness of process, which is considered useful for informing further research design.

FOR SOME YEARS NOW, WESTERN ACADEMICS AND POLICY-MAKERS HAVE embraced the cause of democratic reform in Central and Eastern Europe. To take but one well-known example, President Clinton in the 1994 State of the Union Address cited the absence of war among democracies as a reason for promotion of democracy around the world. Assistance to former Warsaw Pact and newly independent states has been made conditional to varying degrees on the acceptance of democratic change. The Organization for Security and Cooperation in Europe, the European Union, the United States Agency for International Development and associated non-governmental organizations have unleashed armies of promoters of democracy throughout the region to: observe elections; monitor human rights; draft new constitutions and laws defending civil and political rights; train judges and police personnel; and organize and assist political parties, media and non-governmental pressure groups. In short, they have sought to transplant the fabric of civil society and democratic institutions. These armies have landed on terrain often quite foreign to them and have often displayed little sensitivity to the social, economic and political context in which they are operating. This may have contributed to results other than those intended.

The chemical and petrochemical industries have decades of experience in specifying metallic piping lined with non-metals as a cost effective alternative to high-priced alloy materials of construction for piping in corrosive service. Early on, application of plastic piping was essentially limited to atmospheric chemical sewage service and to above-ground vents and drains. However, applications and usage of plastic piping continue to increase as engineers become more confident in specifying plastic materials and mechanical contractors gain experience with their installation. Non-metallic materials are being developed that are not only corrosion resistant but also have increasingly higher pressure and temperature capabilities. Plastic double-containment piping has experienced tremendous growth for handling hazards and toxic fluids. In the United States, recent dramatic growth of plastic double-containment piping applications has been, to a large extent, for compliance with the Environmental Protection Agency (EPA) regulations of the 1976 Resource Conservation and Recovery Act (RCRA). Related EPA regulatory efforts were accelerated in 1988 by more stringent amendments to this legislation. Industry in the United States must comply with these EPA regulations by December 1998. Plastic piping and metallic piping lined with non-metals have been covered to some extent by the ASME B31.3 Chemical Plant and Petroleum Refinery Piping Code for several years. The distinctive requirements of non-metallic piping and piping lined with non-metals were incorporated into the 1980 edition as a separate Chapter VII, which is dedicated to this growing area of interest in piping. This paper provides an overview of the present coverage of non-metallic piping lined with non-metals in the ASME B31.3 Chemical Plant and Petroleum Refinery Piping Code (1). Some topics that warrant further investigation are presented as well.

This article sheds light on the role of foreign direct investment as an instrument for economic development and, in turn, for the advancement of U.S. foreign policy goals during the Cold War. From the earliest days of the Cold War, and especially after the U.S.-Soviet competition for influence in the developing world began in the 1950s, the United States sought to promote private enterprise on behalf of U.S. goals. In the late 1940s and early 1950s, U.S. officials believed that foreign investment would suffice to fuel international development, obviating the need for official development assistance. These hopes, however, were largely disappointed. On the one hand, U.S.-based multinational companies preferred to invest in the industrial world; on the other hand, some Third World governments were uninterested in promoting private enterprise rather than state-led development. In part because foreign investment did not meet expectations, the U.S. government ended up elaborating an official foreign aid program instead.

Multilateral donors like the World Bank and bilateral agencies such as the United States Agency for International Development (USAID) and the British Department for International Development exert a great deal of influence in international educational development — particularly in sub-Saharan Africa — both in the programs they fund and the types of research they engage in. In this article, Richard Maclure investigates educational research in Africa and juxtaposes research done by large, exogenous, Western, results-oriented organizations with research performed by smaller, endogenous, local researchers aided by local research networks. Maclure argues convincingly that research that falls into the exogenous "donor-control" paradigm far too often is irrelevant to the African educational policy context and does little to develop local research capacity. The cases of two African research networks — the Educational Research Network of West and Central Africa and the Association for the Development of Education in Africa—are presented as exemplars of organizations that promote an alternative type of research that is endogenous, relevant to policy and the process of policymaking, and controlled by Africans. Maclure concludes with a call for increased support for and development of these types of networks, and for the development of the long-term solution to educational research in Africa — the university.

The study of vulnerability constitutes a central axis in research work on sustainability. Social vulnerability (SV) analyzes differences in human capacity to prepare, respond and recover from the impact of a natural hazard. Although disasters threaten all the people who suffer from them, they do not affect all members of society in the same way. Social and economic inequalities make certain groups more vulnerable. Factors such as age, sex, social class and ethnic identity increase vulnerability to a natural disaster. Ten years after the earthquake in Haiti in 2010, this work deepens the relationship between natural disasters, SV and gender, exploring the unequal distribution of the SV in the face of a seismic risk. The source of statistical information has been obtained from the Demographic and Health Survey (DHS), developed by the United States Agency for International Development (USAID). Multicriteria decision techniques (TOPSIS) and the differences in differences (DID) technique are used to analyze variations in gender inequality in SV as a result of the catastrophic event. The results obtained reinforce the idea of the negative impact of the disaster on the SV. Additionally, an intensification of the negative effects is observed when the household is headed by a woman, increasing the gap in SV between households headed by women and the rest of the households. The conclusions obtained show additional evidence of the negative effects caused by natural disasters on women, and important implications for disaster risk management are derived that should not be ignored.
