Can You Predict the Future by Looking at the Past? Since accurate forecasting requires more than just inserting historical data into a model, Forecasting: Methods and Applications, 3/e, adopts a managerial, business orientation. Integrated throughout this text is the innovative idea that explaining the past is not adequate for predicting the future. Inside, you will find the latest techniques used by managers in business today, discover the importance of forecasting and learn how it's accomplished. And you'll develop the necessary skills to meet the increased demand for thoughtful and realistic forecasts. New features in the third edition include:
* An emphasis placed on the practical uses of forecasting.
* All data sets used in this book are available on the Internet.
* Comprehensive coverage provided on both quantitative and qualitative forecasting techniques.
* Includes many new developments in forecasting methodology and practice.

Applied Smoothing Techniques for Data Analysis - The Kernel Approach with S-Plus Illustrations (Hardcover): Adrian W. Bowman,... Applied Smoothing Techniques for Data Analysis - The Kernel Approach with S-Plus Illustrations (Hardcover)
Adrian W. Bowman, Adelchi Azzalini
R2,236 Discovery Miles 22 360 Ships in 4 - 6 working days

The book describes the use of smoothing techniques in statistics, including both density estimation and nonparametric regression. Considerable advances in research in this area have been made in recent years. The aim of this text is to describe a variety of ways in which these methods can be applied to practical problems in statistics. The role of smoothing techniques in exploring data graphically is emphasized, but the use of nonparametric curves in drawing conclusions from data, as an extension of more standard parametric models, is also a major focus of the book. Examples are drawn from a wide range of applications. The book is intended for those who seek an introduction to the area, with an emphasis on applications rather than on detailed theory. It is therefore expected that the book will benefit those attending courses at an advanced undergraduate, or postgraduate, level, as well as researchers, both from statistics and from other disciplines, who wish to learn about and apply these techniques in practical data analysis. The text makes extensive reference to S-Plus, as a computing environment in which examples can be explored. S-Plus functions and example scripts are provided to implement many of the techniques described. These parts are, however, clearly separate from the main body of text, and can therefore easily be skipped by readers not interested in S-Plus.

Geological journeys - a traveller's guide to South Africa's rocks and landforms is an essential companion for car journeys. For those who wonder about the jaunty tilt of a mountain ahead, the unusual patterns of a road cutting, the colour and texture of the roadside soil, or the purpose of a distant minehead, this volume offers answers and explanations about features along all the major routes across South Africa, and some of the lesser, but geologically interesting, routes too.

Also included are the three main metropolitan areas – Johannesburg, Cape Town and Durban – so that city residents can understand the geological features surrounding them. Using familiar landmarks to pinpoint sites and subtle phenomena, the authors bring to light our rich geological heritage, its likely roots and often tumultuous history.

Along the way, they also discuss the historical background, personalities and stories that relate to the landscape.

Reviews from the First Edition:

"An excellent text a ] The postulates of quantum mechanics and the mathematical underpinnings are discussed in a clear, succinct manner." (American Scientist)

"No matter how gently one introduces students to the concept of Diraca (TM)s bras and kets, many are turned off. Shankar attacks the problem head-on in the first chapter, and in a very informal style suggests that there is nothing to be frightened of." (Physics Bulletin)

Reviews of the Second Edition:

"This massive text of 700 and odd pages has indeed an excellent get-up, is very verbal and expressive, and has extensively worked out calculational details---all just right for a first course. The style is conversational, more like a corridor talk or lecture notes, though arranged as a text. a ] It would be particularly useful to beginning students and those in allied areas like quantum chemistry." (Mathematical Reviews)

R. Shankar has introduced major additions and updated key presentations in this second edition of Principles of Quantum Mechanics. New features of this innovative text include an entirely rewritten mathematical introduction, a discussion of Time-reversal invariance, and extensive coverage of a variety of path integrals and their applications. Additional highlights include:

- Clear, accessible treatment of underlying mathematics

- A review of Newtonian, Lagrangian, and Hamiltonian mechanics

- Student understanding of quantum theory is enhanced by separate treatment of mathematical theorems and physical postulates

- Unsurpassed coverage of path integrals and their relevance in contemporary physics

The requisite text foradvanced undergraduate- and graduate-level students, Principles of Quantum Mechanics, Second Edition is fully referenced and is supported by many exercises and solutions. The booka (TM)s self-contained chapters also make it suitable for independent study as well as for courses in applied disciplines.

R576 Discovery Miles 5 760 Ships in 9 - 17 working days

The second edition of this popular textbook provides an introduction to the principles and methods of epidemiology. Since publication of the first edition in 1993, Basic epidemiology has become a standard reference for education, training and research in the field of public health and has been translated into more than 25 languages. It is used widely, for training public health and environment professionals, undergraduate medical students, and students in other health professions. The second edition provides updated examples of how and why the basics of epidemiology are essential to anyone who is required to understand and apply the principles of disease causation and prevention. The book has a particular emphasis on modifiable environmental factors and encourages the application of epidemiology to the prevention of disease and the promotion of health, including environmental and occupational health. It prepares members of the health-related professions to respond to the need for health services to address all aspects of the health of populations, and to ensure that health resources are used to the best possible effect. It shows how good clinical practice is informed by clinical epidemiology; and its lively, concise style is designed to stimulate a continuing interest in the subject. This edition includes comprehensive chapters on the nature and uses of epidemiology; the epidemiological approach to defining and measuring the occurrence of health-related states in populations; the strengths and limitations of epidemiological study designs, causation, the contribution of epidemiology to the prevention of disease, the promotion of health and the development of health policy, and the role of epidemiology in evaluating the effectiveness and efficiency of health care. It enables students to describe the common causes of death, disease and disability in her or his community; outline appropriate study designs to answer specific questions concerning disease causation, natural history, prognosis, prevention, and the evaluation of therapy and other interventions to control disease, and critically evaluate the literature.

In 1994, Malawi adopted an unusually progressive Constitution, unprecedented in the country's political and constitutional history. 'Human Rights under the Malawian Constitution' takes stock of the human rights jurisprudence generated by the new Constitution and the new judiciary in Malawi over the past sixteen years. The book examines the largely unreported Malawian cases and legislation and systematically analyses them with a view to constructing a coherent corpus of human rights jurisprudence, which is essential to consolidating democracy, establishing the foundation for the rule of law and ushering in an era of accelerated development in Malawi. The author draws on a wealth of international and comparative jurisprudence, including that from other African countries, without detracting from the main objective of constructing a Malawian brand of jurisprudence. Ultimately the book reveals that it is possible for human rights to grow even in underdeveloped countries. 'Human Rights under the Malawian Constitution' is intended for use by judges, lawyers, legal scholars, students, civil society, law reform officers, human rights institutions and comparative law scholars. _______________________________________________ Danwood Mzikenge Chirwa is Associate Professor of Law and Head of the Department of Public Law at the University of Cape Town. He has published widely in the fields of constitutional and human rights law. _______________________________________________ ' This book] makes a significant contribution to African constitutional law. The author has engaged in a careful and systematic treatment of all of the clauses contained in Malawi's Bill of Rights, as well as the jurisprudence which has been developed by its courts over the past 16 years .... Accordingly, this is a work which anyone who wishes to engage in African constitutional law in general and Malawian law in particular will be required to use as a major source of reference.' Dennis Davis, Judge of the High Court of South Africa; Honorary Professor of Law, University of Cape Town ' This book] fills a gap in the literature of human rights in the region with its excellent examination of the Malawian provisions. It is well written and will appeal to a wider readership than Malawi.' Boyce Wanda, Professor of Law, University of Fort Hare

R808 R727 Discovery Miles 7 270 Save R81 (10%) Ships in 4 - 8 working days

Res Ipsa Loquitur and Medical Negligence: A Comparative Survey analyses the application of the doctrine of res ipsa loquitur ('it speaks for itself') to medical negligence cases. The book aims to establish conclusively that the approach of the South African courts, that the doctrine should never find application in medical negligence cases, is untenable and out of touch with modern approaches adopted in other countries. Constitutional principles such as procedural equality, access to courts, access to health care, access to information, post-constitutional legislation, medical ethics and policy considerations are also discussed.

The book further provides a theoretical and practical legal framework for the application of the doctrine to medical negligence cases in South Africa in future. The authors argue for the application of the doctrine, not only in medical negligence cases, but also to related legal procedures that follow a medical accident such as medical inquests, criminal prosecutions and disciplinary inquiries instituted by the Health Professions Council of South Africa.

Res Ipsa Loquitur and Medical Negligence includes a comprehensive comparison of the practical application of the doctrine to medical negligence cases in South Africa, England and the United States of America.

Winner of the Hugo Award and the Nebula Award for Best Novella!

Her name is Binti, and she is the first of the Himba people ever to be offered a place at Oomza University, the finest institution of higher learning in the galaxy. But to accept the offer will mean giving up her place in her family to travel between the stars among strangers who do not share her ways or respect her customs.

Knowledge comes at a cost, one that Binti is willing to pay, but her journey will not be easy. The world she seeks to enter has long warred with the Meduse, an alien race that has become the stuff of nightmares. Oomza University has wronged the Meduse, and Binti's stellar travel will bring her within their deadly reach.

If Binti hopes to survive the legacy of a war not of her making, she will need both the gifts of her people and the wisdom enshrined within the University, itself -- but first she has to make it there, alive.
