"Who were the first humans to inhabit North America? According to the now familiar story, mammal hunters entered the continent some 12,000 years ago via a land bridge that spanned the Bering Sea and introduced the distinctive stone tools of the Clovis culture. Drawing from original archaeological analysis, paleoclimatic research, and genetic studies, noted archaeologists Dennis J. Stanford and Bruce A. Bradley challenge that narrative. Their hypothesis places the technological antecedents of Clovis technology in Europe, with the culture of Solutrean people in France and Spain more than 20,000 years ago, and posits that the first Americans crossed the Atlantic by boat and arrived earlier than previously thought."--Back cover.

This splendid guide to tree identification contains more than 1,000 full-color photographs. Each tree is illustrated in full detail -- by leaf, flower, fruit, bark, and mature tree shape -- and is fully described in the text. A unique leaf index makes the identification of trees simple and accurate. The trees are arranged alphabetically by Latin name and an index of common names concludes the book. An indispensable companion for both the enthusiast and the botanist.

The public provision of early childhood education has developed at different rates across individual countries over the past two centuries. This book provides the historical background to explain how these national differences occurred, with particular reference to welfare and educational systems, to highlight how particular influences grew.

As economic and military walls have come down in the post-Cold War era, states have rapidly built new barriers to prevent a perceived invasion of undesirables. This work examines the practice, politics, and consequences of building these walls.

Border security has been high on public-policy agendas in Europe and North America since the September 11, 2001 attacks on the World Trade Centre in New York City and on the headquarters of the American military in Washington DC. Governments are now confronted with managing secure borders, a policy objective that in this era of increased free trade and globalization must compete with intense cross-border flows of people and goods. Border-security policies must enable security personnel to identify, or filter out, dangerous individuals and substances from among the millions of travelers and tons of goods that cross borders daily, particularly in large cross-border urban regions. This book addresses this gap between security needs and an understanding of borders and borderlands. Specifically, the chapters in this volume ask policy-makers to recognize that two fundamental elements define borders and borderlands: first, human activities (the agency and agent power of individual ties and forces spanning a border), and second, the broader social processes that frame individual action, such as market forces, government activities (law, regulations, and policies), and the regional culture and politics of a borderland. Borders emerge as the historically and geographically variable expression of human ties exercised within social structures of varying force and influence, and it is the interplay and interdependence between people's incentives to act and the surrounding structures (i.e. constructed social processes that contain and constrain individual action) that determine the effectiveness of border security policies. This book argues that the nature of borders is to be porous, which is a problem for security policy makers. It shows that when for economic, cultural, or political reasons human activities increase across a border and borderland, governments need to increase cooperation and collaboration with regard to security policies, if only to avoid implementing mismatched security policies.

"John W. I. Lee and Michael North bring together international and interdisciplinary scholars to analyze a wide scope of border issues and to encourage a nuanced dialogue addressing the concepts and processes of borderlands"--
