Residential segregation is a key issue for good governance in Latin American cities. It demonstrates the high degree of residential segregation of contemporary Latin American cities and discusses implications for the welfare of urban residents.

There is a revival of interest by economists in ethical issues and beliefs, and by moral philosophers and theologians in economics. This book is intended to make a contribution to this cross-fertilisation of ideas. Rodney Wilson has undertaken an extensive survey of Jewish, Christian and Muslim views on economics, and reviewed the rapidly expanding business ethics literature from a religious perspective. The juxtaposition of the work of theologians and moral philosophers with that of economists results in some interesting comparisons.

During the past two decades representations of noncompact Lie groups and Lie algebras have been studied extensively, and their application to other branches of mathematics and to physical sciences has increased enormously. Several theorems which were proved in the abstract now carry definite mathematical and physical sig­ nificance. Several physical observations which were not understood before are now explained in terms of models based on new group-theoretical structures such as dy­ namical groups and Lie supergroups. The workshop was designed to bring together those mathematicians and mathematical physicists who are actively working in this broad spectrum of research and to provide them with the opportunity to present their recent results and to discuss the challenges facing them in the many problems that remain. The objective of the workshop was indeed well achieved. This book contains 31 lectures presented by invited participants attending the NATO Advanced Research Workshop held in San Antonio, Texas, during the week of January 3-8, 1993. The introductory article by the editors provides a brief review of the concepts underlying these lectures (cited by author [*]) and mentions some of their applications. The articles in the book are grouped under the following general headings: Lie groups and Lie algebras, Lie superalgebras and Lie supergroups, and Quantum groups, and are arranged in the order in which they are cited in the introductory article. We are very thankful to Dr.

Mankind has created pollution, and has suffered its consequences since time immemorial. This has intesified greatly since the industrial revolution. One of the main problems in society, and a major function of government is how to cope with this pollution. 80 years ago the maxim used to be "the solution to pollution is dilution"; to dilute any pollted water supply in a large river, or to build a tall chimney stack to dilute air pollutants into the air so that concentrations of pollutants are always low. Since 1950 western countries have gone further and made major attempts to reduce the emissions of the most important pollutants. The discussion of what is an important pollutant has changed. To S02 and heavy metals such as cadmium or arsenic we now add fine particles and even (when we discuss global climate change) C02. The experience and practice of the western countries was only partly followed in the USSR (although the switch from use of coal to natural gas in major cities around 1970 was very important). Since the collapse of the USSR it has become fashionable both in the west and inside Russia to blame all society's ills on pollution. The statistics do not bear out that conclusion, but pollution remains an important issue which can be reduced without significant detriment to other societal values.
