The selection of waste heat rejection systems for steam-electric power plants involves a trade-off among environmental, energy and water conservation, and economic factors. This study compares four general types of cooling systems on the basis of these factors. The cooling systems chosen for study are: once-through systems including surface canals and submerged multiport diffusers; shallow closed cycle cooling ponds; mechanical and natural draft evaporative cooling towers; and mechanical draft dry towers. The cooling system comparison involves, first, an optimization of each cooling system and then a comparison among optimal systems. Comparison is made for an 800 MWe fossil unit and a 1200 MWe nuclear unit located at a hypothetical midwestern river site. A set of models has been developed to optimize the components of each cooling system based on the local meteorological and hydrological conditions at the site in accordance with a fixed demand, scalable plant concept. This concept allows one to compare the costs of producing the same net power from each plant/cooling system. Base case economic parameters were used to evaluate the optimum system for each of the four general cooling systems followed by a sensitivity study for each parameter. Comparison of energy and water consumption follows from the results of the performance model, while comparison of environmental impacts is mostly qualitative. Some quantitative modelling was performed for the environmental effects of thermal discharges from once-through systems, fogging from wet cooling towers and water consumption from the ponds, wet towers and once-through. The results of the optimization models of each of the systems are compared on the basis of: performance - discrete distributions of environmental conditions and transient simulation; economics - using base case scenarios and sensitivity values to arrive at costs expressed in terms of production costs, annualized costs and present value costs; energy and water consumption; and environmental effects. The once-through systems were found to be the least expensive of the four systems, the most energy efficient, but potentially the most environmentally damaging. On the other extreme, dry cooling towers are the most environmentally sound while being the most expensive and least energy efficient. Finally, the results of the economic optimization are compared with results from previous comparative studies.

The last quarter of the twentieth century was a very important period in history of education. Beginning with the so-called 'Great Debate', the period witnessed intense public and political interest in educational issues, culminating in an almost unprecedented amount of education-related legislation, the most symbolic of which was the Education Reform Act of 1988. Some scholars have rightly claimed that the education system was 'transformed' during this period, pointing to major changes in the ways in which schools, further education colleges and universities were organised, managed and controlled. Others have claimed that these changes altered the power relationships which had underpinned the education system since 1944. Given the sheer scale and pace of the education-policy related reforms of this period, this edited collection brings together some of the leading scholars in education to reflect on the major legislative and structural changes in education over the past few decades. Published in the year of the twenty-fifth anniversary of Callaghan's Ruskin College speech in 1976, it provides a definitive contemporary history of education policy in the late twentieth century. The editors bring together some of the leading educationalists to reflect on the major legislative and structural changes in the field over the last twenty five years. The book will be of use to education students on undergraduate and postgraduate courses, as well as students and academics working in social policy.

The notion of "Quality" in business performance has exploded since the publication of the first edition of this classic text in 1989. Today there is a plethora of performance improvement frameworks including Baldrige, EFQM, Lean, Six Sigma and ISO 9001, offering a potentially confusing variety of ways to achieve business excellence. Quality guru John Oakland’s famous TQM model, in many ways a precursor to these frameworks, has evolved to become the ultimate holistic overview of performance improvement strategy. Incorporating the frameworks that succeeded it, the revised model redefines Quality by: Accelerating change Reducing cost Protecting reputation Oakland’s popular, practical, jargon-free style, along with ten case studies eight of which are brand new, effortlessly ties the model to its real-life applications, making it easy to understand how to apply what you’ve learned to your practices and a achieve sustainable competitive advantage. Total Quality Management and Operational Excellence: Text with Cases (Fourth Edition) is supplemented for the first time with a suite of online teaching aids for busy tutors. This exciting update of a classic text is perfect for all students studying for professional qualifications in the management of quality, or those studying science, engineering or business and management who need to understand the part TQM may play in their subjects.

Local government organisation and management in Britain is in the throes of a major transformation brought about by changing economic, social and political circumstances and central government legislation. This book outlines the major pressures for change and analyses and assesses local government's response in terms of role, culture, structure and internal process. Particular attention is paid to the consequences of new decentralised, competitive/regulatory and enabling models of what local authorities should be like in the mid 1990s.

The development of Islamic economics has been profound over the last twenty years. The excellent survey of Muslim Economic Thinking by Mohammad Nejatullah Siddiqi (Ahmad 1980) demonstrates the progress that has been made in every avenue of economic thought; the recent work by M. Khan and A. Mirakhor on Islamic Banking in Pakistan and Iran represents the first major study to quantify the effectiveness of an Islamic monetary system. The book by Dr. Umer Chapra, Towards a Just Monetary System, which is the subject matter of this review article, is an attempt, or so we are told by Khurshid Ahmad in the preface, to provide a "comprehensive and interpretative study of the Islamic monetary system" (P. 12), to "integrate theory and practice" and to "give a vigorous analysis of some key concepts" (P.13) in Islamic monetary economics. The reader is therefore given very high expectations of the book as the beginning of the fourth phase of Islamic economies - "a more integrative as well as more critical approach to the entire theory and practice of money and banking in Islam" (P.11). If these expectations are fulfilled Chapra has claim to pioneering work in Islamic macroeconomics but is this the case?
