  fog ccsf edu: In the Light of Evolution National Academy of Sciences, 2009-01-22 The current extinction crisis is of human making, and any favorable resolution of that biodiversity crisis-among the most dire in the 4-billion-year history of Earth-will have to be initiated by mankind. Little time remains for the public, corporations, and governments to awaken to the magnitude of what is at stake. This book aims to assist that critical educational mission, synthesizing recent scientific information and ideas about threats to biodiversity in the past, present, and projected future. This is the second volume from the In the Light of Evolution series, based on a series of Arthur M. Sackler colloquia, and designed to promote the evolutionary sciences. Each installment explores evolutionary perspectives on a particular biological topic that is scientifically intriguing but also has special relevance to contemporary societal issues or challenges. Individually and collectively, the ILE series aims to interpret phenomena in various areas of biology through the lens of evolution, address some of the most intellectually engaging as well as pragmatically important societal issues of our times, and foster a greater appreciation of evolutionary biology as a consolidating foundation for the life sciences.

  fog ccsf edu: Disability & the Politics of Education Susan Lynn Gabel, Scot Danforth, 2008 Disability and the Politics of Education: An International Reader is a rich resource that deals comprehensively with the many aspects of the complex topic of disability studies in education. For nearly two decades, global attention has been given to education as a human right through global initiatives such as Education for All (EFA) and the Salamanca Statement. Yet according to UNESCO, reaching the goals of EFA remains one of the most daunting challenges facing the global community. Today, millions of the world's disabled children cannot obtain a basic childhood education, particularly in countries with limited resources. Even in the wealthiest countries, many disabled children and youth are educationally segregated from the nondisabled, particularly if they are labeled with significant cognitive impairment. International agencies such as the United Nations and the World Bank have generated funds for educational development but, unfortunately, these funds are administered with the assumption that «west is best», thereby urging developing countries to mimic educational policies in the United States and the United Kingdom in order to prove their aid-worthiness. This «McDonaldization» of education reproduces the labeling, resource allocation, and social dynamics long criticized in disability studies. The authors in this volume explore these subjects and other complexities of disability and the politics of education. In doing so, they demonstrate the importance and usefulness of international perspectives and comparative approaches.

Designed and written for the bird enthusiast who is traveling for reasons other than birding--on business, with family, for academic conferences--the book offers assistance in locating birds, identifying local bird residents, and using public transportation. Where to Watch Birds in World Cities deserves a permanent place in the suitcase or briefcase of anyone who would like to make the most of limited time in an unfamiliar city by learning about the local birds. Entries for each of the sixty cities provide an introduction to the city and detailed information on major bird-watching sites, including lists of typical summer and winter bird residents and migrants and directions for getting to the sites using public transportation. The book is illustrated throughout with maps and attractive line drawings. In no way a replacement for detailed guides to specific cities or regions, this book instead fills an important gap for travelers whose birding, though done on short notice, can nevertheless prove delightful.

Fountain, 2012 This is the Second Edition of THE CREDIT UNION WORLD: Theory, Process, Practice--Cases & Applicaton. The First Edition was released just prior to the financial melt-down and the skyrocketing debt of the United States. As a result of the political and financial upheaval, both in the U.S. and abroad, it was imperative that a second edition be published at this time. Fanny Mae and Freddie Mac, federal government backed mortgages, have been a disaster in the mortgage and housing market, leaving home owners all over America in foreclosure, underwater, or in serious distress. Since the federal government has become so intrusive into the corporate world by taking over entire industries such as automobile factories and meddling directly into the banking industry and Wallstreet in general, these issues do effect the credit union world.
