Available in PDF, EPUB and Kindle. Book excerpt: In 1972 Stephen Jay Gould took the scientific world by storm with his paper on punctuated equilibrium. Challenging a core assumption of Darwin's theory of evolution, it launched the controversial idea that the majority of species originates in geological moments (punctuations) and persists in stasis. Now, thirty-five years later, Punctuated Equilibrium offers his only book-length testament on a theory he fiercely promoted, repeatedly refined, and tirelessly defended.

Download or read book Punctuated Equilibrium and the Dynamics of U.S. Environmental Policy written by Robert Repetto and published by Yale University Press. This book was released on 2008-10-01 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although many environmental policy issues remain deadlocked for decades with little movement, sometimes breakthroughs occur abruptly. Why do deadlocks persist? Why do major policy shifts occur infrequently? Is it possible to judge when policies are ripe for change?This book presents new empirical evidence that the punctuated equilibrium theory of policy dynamics fits the facts of environmental policy change and can explain how stable policies can suddenly unravel in discontinuous change. The distinguished contributors to the volume apply the theory to a wide range of important environmental and resource issues and assess case histories in water, forestry, fisheries, public lands, energy and climate some of which resulted in breakthroughs, others in stalemate. They offer insights into the political conditions and tactics that are likely to produce these disparate outcomes. Every professional, activist, and student concerned with promoting (or resisting) change in environmental and natural resources policies will find this up-to-date book an invaluable guide.

Available in PDF, EPUB and Kindle. Book excerpt: The world’s most revered and eloquent interpreter of evolutionary ideas offers here a work of explanatory force unprecedented in our time—a landmark publication, both for its historical sweep and for its scientific vision. With characteristic attention to detail, Stephen Jay Gould first describes the content and discusses the history and origins of the three core commitments of classical Darwinism: that natural selection works on organisms, not genes or species; that it is almost exclusively the mechanism of adaptive evolutionary change; and that these changes are incremental, not drastic. Next, he examines the three critiques that currently challenge this classic Darwinian edifice: that selection operates on multiple levels, from the gene to the group; that evolution proceeds by a variety of mechanisms, not just natural selection; and that causes operating at broader scales, including catastrophes, have figured prominently in the course of evolution. Then, in a stunning tour de force that will likely stimulate discussion and debate for decades, Gould proposes his own system for integrating these classical commitments and contemporary critiques into a new structure of evolutionary thought. In 2001 the Library of Congress named Stephen Jay Gould one of America’s eighty-three Living Legends—people who embody the “quintessentially American ideal of individual creativity, conviction, dedication, and exuberance.” Each of these qualities finds full expression in this peerless work, the likes of which the scientific world has not seen—and may not see again—for well over a century.

Available in PDF, EPUB and Kindle. Book excerpt: Theories of the Policy Process provides a forum for the experts in policy process research to present the basic propositions, empirical evidence, latest updates, and the promising future research opportunities of each policy process theory. In this thoroughly revised fifth edition, each chapter has been updated to reflect recent empirical work, innovative theorizing, and a world facing challenges of historic proportions with climate change, social and political inequities, and pandemics, among recent events. Updated and revised chapters include Punctuated Equilibrium Theory, Multiple Streams Framework, Policy Feedback Theory, Advocacy Coalition Framework, Narrative Policy Framework, Institutional and Analysis and Development Framework, and Diffusion and Innovation. This fifth edition includes an entirely new chapter on the Ecology of Games Framework. New authors have been added to most chapters to diversify perspectives and make this latest edition the most internationalized yet. Across the chapters, revisions have clarified concepts and theoretical arguments, expanded and extended the theories’ scope, summarized lessons learned and knowledge gained, and addressed the relevancy of policy process theories. Theories of the Policy Process has been, and remains, the quintessential gateway to the field of policy process research for students, scholars, and practitioners. It’s ideal for those enrolled in policy process courses at the undergraduate and graduate levels, and those conducting research or undertaking practice in the subject.

Download or read book Agendas and Instability in American Politics written by Frank R. Baumgartner and published by University of Chicago Press. This book was released on 2010-03-15 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: When Agendas and Instability in American Politics appeared fifteen years ago, offering a profoundly original account of how policy issues rise and fall on the national agenda, the Journal of Politics predicted that it would “become a landmark study of public policy making and American politics.” That prediction proved true and, in this long-awaited second edition, Bryan Jones and Frank Baumgartner refine their influential argument and expand it to illuminate the workings of democracies beyond the United States. The authors retain all the substance of their contention that short-term, single-issue analyses cast public policy too narrowly as the result of cozy and dependable arrangements among politicians, interest groups, and the media. Jones and Baumgartner provide a different interpretation by taking the long view of several issues—including nuclear energy, urban affairs, smoking, and auto safety—to demonstrate that bursts of rapid, unpredictable policy change punctuate the patterns of stability more frequently associated with government. Featuring a new introduction and two additional chapters, this updated edition ensures that their findings will remain a touchstone of policy studies for many years to come.
