Six revolving pictures depict the summer and winter animal inhabitants of mountain, lake, seashore, tundra, desert, and forest environments.

This open access book focuses on the concepts, tools and techniques needed to successfully model ever-changing time-series data. It emphasizes the need for general models to account for the complexities of the modern world and how these can be applied to a range of issues facing Earth, from modelling volcanic eruptions, carbon dioxide emissions and global temperatures, to modelling unemployment rates, wage inflation and population growth.

NEW YORK TIMES BESTSELLER * MORE THAN ONE MILLION COPIES SOLD “A provocative read...There are few tomes that coherently map such broad economic histories as well as Mr. Dalio’s. Perhaps more unusually, Mr. Dalio has managed to identify metrics from that history that can be applied to understand today.” —Andrew Ross Sorkin, The New York Times From legendary investor Ray Dalio, author of the #1 New York Times bestseller Principles, who has spent half a century studying global economies and markets, Principles for Dealing with the Changing World Order examines history’s most turbulent economic and political periods to reveal why the times ahead will likely be radically different from those we’ve experienced in our lifetimes—and to offer practical advice on how to navigate them well. A few years ago, Ray Dalio noticed a confluence of political and economic conditions he hadn’t encountered before. They included huge debts and zero or near-zero interest rates that led to massive printing of money in the world’s three major reserve currencies; big political and social conflicts within countries, especially the US, due to the largest wealth, political, and values disparities in more than 100 years; and the rising of a world power (China) to challenge the existing world power (US) and the existing world order. The last time that this confluence occurred was between 1930 and 1945. This realization sent Dalio on a search for the repeating patterns and cause/effect relationships underlying all major changes in wealth and power over the last 500 years. In this remarkable and timely addition to his Principles series, Dalio brings readers along for his study of the major empires—including the Dutch, the British, and the American—putting into perspective the “Big Cycle” that has driven the successes and failures of all the world’s major countries throughout history. He reveals the timeless and universal forces behind these shifts and uses them to look into the future, offering practical principles for positioning oneself for what’s ahead.

Scientists tell us that climate change is upon us and the physical world is changing quickly with important implications for biodiversity and human well-being. Forests cover vast regions of the globe and serve as a first line of defense against the worst effects of climate change, but only if we keep them healthy and resilient. Forests in Our Changing World tells us how to do that. Authors Joe Landsberg and Richard Waring present an overview of forests around the globe, describing basic precepts of forest ecology and physiology and how forests will change as earth’s climate warms. Drawing on years of research and teaching, they discuss the values and uses of both natural and plantation-based forests. In easy-to-understand terms, they describe the ecosystem services forests provide, such as clean water and wildlife habitat, present economic concepts important to the management and policy decisions that affect forests, and introduce the use of growth-and-yield models and remote-sensing technology that provide the data behind those decisions. This book is a useful guide for undergraduates as well as managers, administrators, and policy makers in environmental organizations and government agencies looking for a clear overview of basic forest processes and pragmatic suggestions for protecting the health of forests.

Explores ecological disasters and the role of scientists and the public in reversing environmental damage

Johannesburg was still a brash mining town, better known for the production of wealth than knowledge, and the University of the Witwatersrand a mere ten years old when, in 1932, these ten lectures were delivered under the auspices of the University Philosophical Society. They portrayed the ideas of the university’s leading academics of the day, and the programme of lectures reveals a studied effort to introduce an element of bipartisan political representation between English and Afrikaner in South Africa by including Wits’ first principal, Jan Hofmeyr, and politician, D.F. Malan, as discussion chairs. Yet, no black intellectuals were represented and, indeed, the politics of racial segregation bursts through the text only in a few of the contributions. For the most part, race is alluded to only in passing. As Saul Dubow explains in his new introduction to this re-issue of the lectures, Our Changing World-View was an occasion for Wits’ leading faculty members to position the young university as a mature institution with a leadership role in public affairs. Above all, it was a means to project the university as a research as well as a teaching institution, led by a vigorous and ambitious cohort of liberal-minded intellectuals. That all were male and white will be immediately apparent to readers of this reissued volume. Ranging from economics, psychology, a spurious rebuttal of evolution to a substantial revisionist history and the perils of the ‘machine age’, this book is a sombre reflection of intellectual history and the academy’s role in promulgating political and social divisions in South Africa.
