One of the most exciting developments in medicine in this century has been the discovery of opioid receptors and their pharmacology. The breadth of know- edge derived from such discovery has truly changed the practice of medicine today. The acceptance by the clinicians of the research data obtained by the basic scientist on spinal opioids is truly amazing. The clinical sequelae of the discovery of opioid receptors has been the development of the technique of intraspinal administration of opioids. In the last decade much has been written about indications, effects, and side effects of intraspinal opioids. The technique has become commonplace for cancer and postoperative pain. However, no standards of care and management of patients with spinally administered opioids have been developed. We need these standards to be developed and universally followed. The monograph was conceived to update clinicians on the applied pharma cology of spinal opioids. We were fortunate to have Drs. N. Rawal and D. Coombs agree to edit this monograph. They have been able to assemble world-renowned experts as contributing authors. It is our hope that the con tents of this book will be stimulating, informative, and useful to the reader. PREFACE Much has been written about the subject of spinal opioid analgesia, includ ing several notable reviews. We were stimulated to assemble this particular volume in this important series on pain management initiated by Dr. Raj for a number of reasons."

Public relations experts and crisis management personnel have done an excellent job over the years of drawing attention to the grand scope of risks associated with crisis. Particularly in the present challenging economic conditions, organizations have become aware of the costs of crises and are willing to put forth effort and resources in crisis prevention. In this book, the editors and contributors offer significant insight into the critical considerations of crisis preparation as well as the importance of anticipation and pre-crisis planning. Pre-crisis planning has been a part of crisis management ever since scholars and practitioners began researching it. This book presents some of the most detailed and thorough insights published to date and serves as an example of where future research can go.

This book presents findings from project R7786 Partnerships to improve access and quality of urban public transport for the urban poor carried out by the authors as part of the Knowledge and Research (KaR) programme of the Infrastructure and Urban Development Department, Department for International Development (DFID) of the British Government. The purpose of the project was to identify, explore, and document critical issues in the provision of transport services for and in low-income settlements in developing countries. The identified issues can be used at policy and operational levels to provide better transport services to low-income communities in urban areas. In the research methodology, a sustainable livelihoods framework was used to set the research framework. The city of Dar es Salaam has grown rapidly since the late 1940s. In the 1948 census the population was 69,227; by the census in 1957 it had grown to 128,742. During this period the city remained highly concentrated, with its boundaries on average less than five kilometres from the sea front or the then town centre. The growth has continued and the estimated population in 2000 was 2,286,730, with a continuing annual growth rate of about 4.5 per cent against the national average of 2.8 per cent.
