Book Description
Southern Silk Route is the historic route, which runs from China to Myanmar and ends up in Assam. The route has historical importance as it served as a major artery of ancient trade articles. The Southern Silk Route: Historical Links and Contemporary Convergences attempts to sketch out the historical dimensions of the route and shows the contemporary dynamics, both positive and negative. It poses the question how history can extend a lesson in contemporary contexts. The book has two parts- theoretical articles on the route judging from a scholar’s perspective on one hand and explorers’ insight in the practical perspective on the other, thus making it really interesting both for the scholar and the lay reader. Please note: Taylor & Francis does not sell or distribute the Hardback in India, Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka

Book Description
This 1982 collection of eight original anthropological essays provides an exciting synthesis of theory and practice in one of the key issues of contemporary cultural evolutionary thought. The contributors ask why complex, highly stratified societies emerged at several locations in the New World at the same point in prehistory. Focusing primarily on the initial centers of civilization in Mesoamerica and the Andean region, they consider the sociopolitical, environmental and ideological factors in state formation. The essays discuss the prehistoric conditions and processes that simulated the development of the first state-level societies in Mesoamerica and Peru, and explore the difficulties archaeologists must face in their direct analysis of physical remains. In general, the contributors recognize a growing need for better archaeological solutions to the question of state origin and for more sensitivity to the problems as well as to the possibilities of ethnographic analogy.

Book Description
This bold and controversial argument shows why energy transitions are inherently complex and prolonged affairs, and how ignoring this fact raises unrealistic expectations that the United States and other global economies can be weaned quickly from a primary dependency on fossil fuels. Energy transitions are fundamental processes behind the evolution of human societies: they both drive and are driven by technical, economic, and social changes. In a bold and provocative argument, Energy Transitions: History, Requirements, Prospects describes the history of modern society's dependence on fossil fuels and the prospects for the transition to a nonfossil world. Vaclav Smil, who has published more on various aspects of energy than any working scientist, makes it clear that this transition will not be accomplished easily, and that it cannot be accomplished within the timetables established by the Obama administration. The book begins with a survey of the basic properties of modern energy systems. It then offers detailed explanations of universal patterns of energy transitions, the peculiarities of changing energy use in the world's leading economies, and the coming shifts from fossil fuels to renewable conversions. Specific cases of these transitions are analyzed for eight of the world's leading energy consumers. The author closes with perspectives on the nature and pace of the coming energy transition to renewable conversions.

Book Description
This book deals with macro and micro aspects of population change and their inter-face with socio-economic factors and impact. It examines theoretical notions and pursues their empirical manifestations and uses multidisciplinary approaches to population change and diversity. It investigates the organic nature of the relationships between socio-economic factors and population change and the feedback loops that affect socio-economic organisation and behaviour. The book brings together material often scattered in a number of sources and disciplines that helps to understand population change and their socio-economic aspects. In addition to dealing with the more conventional factors in population dynamics in the form of fertility, mortality and migration, the book examines socio-economic forces that influence them. It discusses population evolving attributes that affect population characteristics and social and behaviour and impact on the environment. Further, it deals with social organisation and pathways that lead to different social and economic development and standards of living of diverse populations.

Book Description
"Inspired by the spectacular discoveries of the past two decades from the Age of Reptiles in China, Riddle of the Feathered Dragons explores how these miraculous fossils have transformed the contentious arena of bird and dinosaur evolution. Aside from being the most comprehensive discussion of these avian and associated discoveries, the author delves into the world of investigative journalism to expose the darker side of the world of fossil birds and dinosaurs. The book exposes the massive unfounded speculation that has characterized the field of vertebrate paleontology and published extensively in the world's most prestigious journals, including everything from supposed dinosaur protein to so-called feathered dinosaurs. The book questions the validity of the foundational tenets of the now "unquestionable orthodoxy" of bird and dinosaur evolution, including bird origins, feathered dinosaurs, flight origin from the ground-up and hot-blooded dinosaurs and their proteins. It exposes how speculation has gone far beyond the ability of the currently available evidence to yield answers. The author concludes that birds are best defined by a more traditional definition of the possession of feathers and avian flight architecture, that the so-called "feathered dinosaurs" are most likely derived avians, and that flight clearly originated from the trees-down, from ancestors that antedated the dinosaurs, rather than a direct linear descent"--
