The Canadian Shield is a distinct ecological region that forms the evergreen, granite-studded crown stretching across two-thirds of North America. In size, it approximates western Europe with one percent the number of people. A satellite view of the region on a winter's night shows tiny, widely scattered blips of light-islands of human settlement adrift in a sea of subarctic wilderness. In age, the shield's primeval bedrock dates to the beginning of earthly time. Shield Country unfolds a fascinating story of unrivaled Precambrian geology, of wild rivers and millions of pristine lakes, of an ecological junction where subarctic and arctic climates, plants, birds, and mammals weave a richly textured wilderness fabric.

There is extraordinary variation in how governments treat multinational corporations in emerging economies; in fact, governments around the world have nationalized or eaten away at the value of foreign-owned property in violation of international treaties. This even occurs in poor countries, where governments are expected to, at a minimum, respect the contracts they make with foreign firms lest foreign capital flee. In The Shield of Nationality, Rachel Wellhausen introduces foreign-firm nationality as a key determinant of firms' responses to government breaches of contract. Firms of the same nationality are likely to see a compatriot's broken contract as a forewarning of their own problems, leading them to take flight or fight. In contrast, firms of other nationalities are likely to meet the broken contract with apparent indifference. Evidence includes quantitative analysis and case studies that draw on field research in Ukraine, Moldova, and Romania.

Shield Construction Techniques in Tunnelling presents the latest on this fast, environmentally-friendly and relatively safe construction technique, reflecting on its technical risks and challenges as seen in China. Sections introduce the type of shields, the history of the technique, shielding principles, selection, management, the latest techniques in operation, consider engineering cases, discuss construction in gravel, soft-soil, composite, and rock strata, and present video clips of construction that are accessible through QR codes embedded in the text. The book combines theory and practical experience, giving the reader unique insights into shield equipment and construction techniques. The shield tunneling technique is being used very widely, particularly in China, which is building urban-rail transit systems at an unparalleled scale and speed. The use of tunneling-shields provides a fast, relatively-safe, and ecologically-friendly method for the construction of tunnels. However, a number of incidents have shown the risks involved in tunnelling through geologically complex areas. Gives the principles and practice of shield construction techniques, including shield selection and operation Demonstrates the latest technologies in shield construction that can be applied in practice Reflects on the technical risks and challenges of shield construction, based on extensive use of the technique for tunnel construction in China Discusses challenges in construction in gravel, soft-soil, composite and rock strata Provides engineers with applicable insights into shield equipment and construction techniques

Being a Canadian carries with it a tangible sense of living on the edge of a vast barren interior. Only named as such in 1883, the Canadian Shield is an empty immensity of lakes, bogs, rivers, forest and protruding ribs of hard Precambrian crystalline rock that covers more than half of the total land area of Canada. This book traces the geologic evolution of the Shield, its first tentative exploration by humans starting 11,000 years ago as the last great ice sheets withdrew, its changing economic fortunes as Europeans penetrated its remote rocky vastnesses for furs and metals, and its transformation in the twentieth century into a national icon to Canadians. Regarded as 'barren' and of no value, much of the Shield was given away in 1670 to a single London-based fur trading company, the Hudson Bay Company, who jealously guarded its northern domain until 1867. This two hundred year long monopoly created a virtual government over a huge piece of North America. Without the HBC, much of it would have passed into American hands and there would have been no 'Canadian' Shield or country called Canada. As a nation, we are indebted to hard rock.

This dual biography of Malcolm X and Martin Luther King upends longstanding preconceptions to transform our understanding of the twentieth century's most iconic African American leaders. To most Americans, Malcolm X and Martin Luther King Jr. represent contrasting ideals: self-defense vs. nonviolence, black power vs. civil rights, the sword vs. the shield. The struggle for black freedom is wrought with the same contrasts. While nonviolent direct action is remembered as an unassailable part of American democracy, the movement's militancy is either vilified or erased outright. In The Sword and the Shield, Peniel E. Joseph upends these misconceptions and reveals a nuanced portrait of two men who, despite markedly different backgrounds, inspired and pushed each other throughout their adult lives. This is a strikingly revisionist biography, not only of Malcolm and Martin, but also of the movement and era they came to define.
