Buried there lie answers about the origins of humankind. After a century of investigation, scientists have transformed our understanding about the beginnings of human life. But vital clues still remain hidden. In Born in Africa, Martin Meredith follows the trail of discoveries about human origins made by scientists over the last hundred years, recounting their intense rivalry, personal feuds, and fierce controversies as well as their feats of skill and endurance.The results have been momentous. Scientists have identified more than twenty species of extinct humans. They have firmly established Africa as the birthplace not only of humankind but also of modern humans. They have revealed how early technology, language ability, and artistic endeavour all originated in Africa; and they have shown how small groups of Africans spread out from Africa in an exodus sixty thousand years ago to populate the rest of the world. We have all inherited an African past.

    Each chapter is relatively self-contained and can be used as a unit of study. The algorithms are described in English and in a pseudocode designed to be readable by anyone who has done a little programming. The explanations have been kept elementary without sacrificing depth of coverage or mathematical rigor.

    Practicing what you have learned is easy with the CD-ROM that contains more than 4,000 audio files, including recordings of speech from southern and northern U.S. cities, London, Edinburgh, Dublin, New Zealand, other forms of English, and scores of other languages.

    It also covers MySQL, and PostgreSQL. It contains examples which have been tested against each SQL platform, with incompatibilities or platform distinctives called out and explained.

    It is informed by the Cambridge International Corpus and the Cambridge Learner Corpus to ensure that the vocabulary is presented in genuine contexts and includes real learner errors. Also available is Cambridge Vocabulary for Advanced (Band 6.5 or above).

    Presenting an introduction to the philosophy, history and methodology of geography, the book maps the intellectual changes in the discipline over the years. To keep the students abreast with the recent trends in geography, and its methodological problems, the book has been updated and revised, making it a comprehensive textbook on geographical thought. The main objective of the sixth edition is to incorporate a number of relevant new topics and concepts to streamline the text which may go a long way in expanding the geographical base of the interested students about the philosophy and methodology of geography. This new edition is presented in a larger format with all improved maps and illustrations. A whole new chapter now introduces to the students a contemporary sub-discipline of Feminist Geography. A new comprehensive list of biographic notes on selected geographers is also included in this edition. It is hoped that the present edition will prove of immense help for the students and teachers of geography alike. It will also serve the need of the aspirants of various competitive examinations, especially the Indian Administrative Service, the NET and other state level civil services examinations.

     Using case examples of both good and bad student practice, the handbook takes students through each step of the dissertation process, from their initial research proposal to the final submission. The author uses clear illustrations of what students need to do - or not do - to reach their potential, helping them to avoid the most common pitfalls. This essential handbook covers: Producing focused and relevant research objectives Writing your literature review Citing your sources correctly Clearly explaining your use of research methods Writing up your findings Summarizing your work by linking your conclusions to your initial proposal Understanding marking schemes Aimed primarily at Master's students or students on short postgraduate courses in business, humanities and the social sciences, this book is also key reading for supervisors and undergraduates considering postgraduate study.

    The fifth edition preserves the lucid, lively and comprehensive qualities which marked the book in its earlier versions. Numerous student learning aids are provided.

    Working through the book you will develop an arsenal of techniques to help you unlock the meaning of definitions, theorems and proofs, solve problems, and write mathematics effectively. All the major methods of proof - direct method, cases, induction, contradiction and contrapositive - are featured. Concrete examples are used throughout, and you'll get plenty of practice on topics common to many courses such as divisors, Euclidean algorithms, modular arithmetic, equivalence relations, and injectivity and surjectivity of functions. The material has been tested by real students over many years so all the essentials are covered. With over 300 exercises to help you test your progress, you'll soon learn how to think like a mathematician.
