The general theme of this working conference is notations, methods, and tool support for the calculation of programs from specifications. Its purpose is to present the results of ongoing research, descriptions of existing and prosposed systems and applications to the production of practical software. This work, a collection of papers from the conference, aims to address the following topics: the study of the calculation of programs from specifications, the design of notations for such calculation, the formulation of algorithm theories using such notations and the investigation of software support for program derivation. This book should be of interest to computer science students, software researchers and programmers requiring correct codes.

The study of educational leadership makes little sense unless it is in relation to who the leaders are, how they are leading, what is being led, and with what effect. Based on the premise that learning is at the heart of leadership and that leaders themselves should be learners, the Leadership for Learning series explores the connections between educational leadership, policy, curriculum, human resources and accountability. Each book in the series approaches its subject matter through a three-fold structure of process, themes and impact.Series Editors - Clive Dimmock, Mark Brundrett and Les BellThe effects of globalization are evident in education policy around the world. Governments from the United States to China are driving their education systems to produce more skilled, more flexible, more adaptable employees. The pressure to perform is all-pervasive, meaning present-day leaders have to go beyond the principles of humane and equitable management practice and look for a competitive advantage through strategies that enhance motivation, build capacity for organizational improvement, and produce better value-added performance.Human Resource Management in Education debates the fundamental question of how far effective human resource management policies can enable schools and colleges to transcend the paradoxes of the global reform agenda. It analyses the relationship between leadership, the classroom and results, and uses case studies to explore the extent to which performance is enhanced by distributed leadership and constrained by social, political and economic contexts.The book is divided into three parts: examining the current context of human resource management, by critically analysing globalization, human capital theory, and worldwide trends in government legislation, societal values, and teacher culture(s); exploring two pairs of contemporary themes in human resource management, by comparing the roles of leaders and followers, on the one hand, and contrasting learning and greedy organizations, on the other; looking at how the context and the themes impact on particular contemporary practices in human resource management, by analysing the selection and development of professionals, the remodelling of school teams and the management of performance.The authors carefully blend advocacy with evidence to ensure relevance for both practitioner and academic audiences across the globe. The book would be of particular use to students on masters courses in educational leadership.

Richard Bird takes a radical approach to algorithm design, namely, design by calculation. These 30 short chapters each deal with a particular programming problem drawn from sources as diverse as games and puzzles, intriguing combinatorial tasks, and more familiar areas such as data compression and string matching. Each pearl starts with the statement of the problem expressed using the functional programming language Haskell, a powerful yet succinct language for capturing algorithmic ideas clearly and simply. The novel aspect of the book is that each solution is calculated from an initial formulation of the problem in Haskell by appealing to the laws of functional programming. Pearls of Functional Algorithm Design will appeal to the aspiring functional programmer, students and teachers interested in the principles of algorithm design, and anyone seeking to master the techniques of reasoning about programs in an equational style.

Value-added tax (VAT) dominates tax systems around the world. But should every country have a VAT? Is VAT always as good as it could be in economic, equity and administrative terms? In developing and transitional countries the answers to such questions are critical to stability, growth and development. VAT is a critical fiscal tool in most countries. But VAT can sometimes be better designed and almost always better administered. The key questions that must be answered in designing and implementing VAT are essentially the same in all countries. But different tax designs may best suit different countries facing different circumstances. This book reviews experiences with VATs around the world and assesses how the choice of particular design features may affect outcomes in particular contexts.

Richard Bird is famed for the clarity and rigour of his writing. His new textbook, which introduces functional programming to students, emphasises fundamental techniques for reasoning mathematically about functional programs. By studying the underlying equational laws, the book enables students to apply calculational reasoning to their programs, both to understand their properties and to make them more efficient. The book has been designed to fit a first- or second-year undergraduate course and is a thorough overhaul and replacement of his earlier textbooks. It features case studies in Sudoku and pretty-printing, and over 100 carefully selected exercises with solutions. This engaging text will be welcomed by students and teachers alike.

This book is devoted to five main principles of algorithm design: divide and conquer, greedy algorithms, thinning, dynamic programming, and exhaustive search. These principles are presented using Haskell, a purely functional language, leading to simpler explanations and shorter programs than would be obtained with imperative languages. Carefully selected examples, both new and standard, reveal the commonalities and highlight the differences between algorithms. The algorithm developments use equational reasoning where applicable, clarifying the applicability conditions and correctness arguments. Every chapter concludes with exercises (nearly 300 in total), each with complete answers, allowing the reader to consolidate their understanding and apply the techniques to a range of problems. The book serves students (both undergraduate and postgraduate), researchers, teachers, and professionals who want to know more about what goes into a good algorithm and how such algorithms can be expressed in purely functional terms.
