Some 250 million years ago, the earth suffered the greatest biological crisis in its history. Around 95 percent of all living species died out—a global catastrophe far greater than the dinosaurs' demise 185 million years later. How this happened remains a mystery. But there are many competing theories. Some blame huge volcanic eruptions that covered an area as large as the continental United States; others argue for sudden changes in ocean levels and chemistry, including burps of methane gas; and still others cite the impact of an extraterrestrial object, similar to what caused the dinosaurs' extinction. Extinction is a paleontological mystery story. Here, the world's foremost authority on...
Glutton, demon of destruction, symbol of slaughter, mightiest of wilderness villains… The wolverine comes marked with a reputation based on myth and fancy. Yet this enigmatic animal is more complex than the legends that surround it. With a shrinking wilderness and global warming, the future of the wolverine is uncertain. The Wolverine Way reveals the natural history of this species and the forces that threaten its future, engagingly told by Douglas Chadwick, who volunteered with the Glacier Wolverine Project. This five-year study in Glacier National Park – which involved dealing with blizzards, grizzlies, sheer mountain walls, and other daily challenges to survival – uncovered key missing information about the wolverine’s habitat, social structure and reproduction habits. Wolverines, according to Chadwick, are the land equivalent of polar bears in regard to the impacts of global warming. The plight of wolverines adds to the call for wildlife corridors that connect existing habitat that is proposed by the Freedom to Roam coalition.
Sudan's post-independence history has been dominated by political and civil strife. Most commentators have attributed the country's recurring civil war to either to an age-old racial divide between Arabs and Africans , or to recent colonially constructed inequalities. This book attempts a more complex analysis, briefly examining the historical, political, economic and social factors which have contributed to periodic outbreaks of violence between the state and its peripheries. In tracing historical continuities, it outlines the essential differences between the modern Sudan's first civil war in the 1960s and the current war. It also looks at the series of minor civil wars generated by, and contained within, the major conflict, as well as the regional and international factors - including humanitarian aid - which have exacerbated civil violence. This introduction is aimed at students of North-East Africa, and of conflict and ethnicity. It should be useful for people in aid and international organizations who need a straightforward analytical survey.
Africa’s newest nation has a long history. Often considered remote and isolated from the rest of Africa, and usually associated with the violence of slavery and civil war, South Sudan has been an arena for a complex mixing of peoples, languages, and beliefs. The nation’s diversity is both its strength and a challenge as its people attempt to overcome the legacy of decades of war to build a new economic, political, and national future. Most recent studies of South Sudan’s history have a foreshortened sense of the past, focusing on current political issues, the recently ended civil war, or the ongoing conflicts within the country and along its border with Sudan. This brief but substantial overview of South Sudan’s longue durée, by one of the world’s foremost experts on the region, answers the need for a current, accessible book on this important country. Drawing on recent advances in the archaeology of the Nile Valley, new fieldwork as well as classic ethnography, and local and foreign archives, Johnson recovers South Sudan’s place in African history and challenges the stereotypes imposed on its peoples.

In this important new book for pre- and in-service teachers, early math experts Douglas Clements and Julie Sarama show how "learning trajectories" help teachers become more effective professionals. By opening up new windows to seeing young children and the inherent delight and curiosity behind their mathematical reasoning, learning trajectories ultimately make teaching more joyous. They help teachers understand the varying level of knowledge and thinking of their classes and the individuals within them as key in serving the needs of all children. In straightforward, no-nonsense language, this book summarizes what is known about how children learn mathematics, and how to build on what they know to realize more effective teaching practice. It will help teachers understand the learning trajectories of early mathematics and become quintessential professionals.
The role of science in policymaking has gained unprecedented stature in the United States, raising questions about the place of science and scientific expertise in the democratic process. Some scientists have been given considerable epistemic authority in shaping policy on issues of great moral and cultural significance, and the politicizing of these issues has become highly contentious. Since World War II, most philosophers of science have purported the concept that science should be "value-free." In Science, Policy and the Value-Free Ideal, Heather E. Douglas argues that such an ideal is neither adequate nor desirable for science. She contends that the moral responsibilities of scientists ...
