Cities concentrate wealth, people and productivity while consuming much of the world's energy and producing much of the world's greenhouse gas emissions. This concentration makes cities and their populations more at risk to natural disasters and to long-term changes in climate, yet cities also offer vast opportunities to respond to these challenges. Changes in migration, land use, and spatial development will increase vulnerability, especially in developing countries, and rising sea levels will affect millions of people living in coastal cities. Adaptation, mitigation, and increased resilience to climate change are therefore imperative for cities. The links between cities and climate change were the subject of the 5th Urban Research Symposium held in Marseille, France, in June 2009. The eight papers selected and updated for Cities and Climate Change: Responding to an Urgent Agenda reflect the core of the analytical discussion and policy implications discussed at the symposium, combining comprehensive analysis and theoretical insights with examples of best practices from around the world. These include a framework to include aspects of poverty in the discussion of cities and climate change; new perspectives on the knowledge and measurement of climate change, urban infrastructure, institutions and governance, and economic and social issues; and specific case studies comparing experiences of cities in both industrialized and developing countries. This book also includes a summary discussion of the main research themes and abstracts of additional selected papers from the symposium. --Book Jacket.

It is widely recognized that spiral grain in trees severely reduces the value of sawn timber through warping and loss of strength, and that it also causes problems for other wood uses as diverse as transmission poles or plywood. Yet, paradoxically, there are highly valued grain patterns including wavy and interlocked grain, whose origins in the cambium invite direct comparison with those of spiral grain, so that many authorities believe them to be related phenomena. In recent years this concept has prompted extensive research into the anatomy, genetics, and physiology of all such grain patterns in wood. As a result it has become apparent that tree cambia provide excellent systems through which to study the origins of stem polarity and the complex processes of morphogenetic control in plants. Beside these and other pressing topics for research, the book examines methods of measuring grain deviations, and considers their influence on wood properties, on the economics of timber production, and on wood manufacturing.

In this book, the author challenges accepted wisdom about gender identity and sexual orientation. She takes on the medical establishment, the Bible, social science--and even Darwin himself. She leads the reader through a ... discussion of diversity in gender and sexuality among fish, reptiles, amphibians, birds, and mammals, including primates. She argues that principal elements of Darwinian sexual selection theory are false and suggests a new theory that emphasizes social inclusion and control of access to resources and mating opportunity. She disputes a range of scientific and medical concepts, including Wilson's genetic determinism of behavior, evolutionary psychology, the existence of a gay gene, the role of parenting in determining gender identity, and Dawkins's "selfish gene" as the driver of natural selection. She dares social science to respect the agency and rationality of diverse people; shows that many cultures across the world and throughout history accommodate people we label today as lesbian, gay, and transgendered; and calls on the Christian religion to acknowledge the Bible's many passages endorsing diversity in gender and sexuality. In the book, she concludes with bold recommendations for improving education in biology, psychology, and medicine for democratizing genetic engineering and medical practice and for building a public monument to affirm diversity as one of our nation's defining principles.
