This book is relevant to engineers, project developers, foresters, economists, sociologists, environmental scientists and natural resource managers. Most chapters also provide practical hands-on advice for the practitioner, and provide a valuable resource for anyone who is considering developing a woody bioenergy project.

Pell's Equation is a very simple Diophantine equation that has been known to mathematicians for over 2000 years. Even today research involving this equation continues to be very active, as can be seen by the publication of at least 150 articles related to this equation over the past decade. However, very few modern books have been published on Pell's Equation, and this will be the first to give a historical development of the equation, as well as to develop the necessary tools for solving the equation.

The authors provide a friendly introduction for advanced undergraduates to the delights of algebraic number theory via Pell's Equation. The only prerequisites are a basic knowledge of elementary number theory and abstract algebra. There are also numerous references and notes for those who wish to follow up on various topics.

Few things are as certain as societal changes-and the pressing need for educators to prepare students with the knowledge and ways of thinking necessary for the challenges in a changing world. In the forward-thinking pages of Designs for Learning Environments of the Future, international teams of researchers present emerging developments and findings in learning sciences and technologies at the infrastructure, curricular, and classroom levels.
Focusing on ideas about designing innovative environments for learning in areas such as biology, engineering, genetics, mathematics, and computer science, the book surveys a range of learning technologies being explored around the world-a spectrum as diverse as digital media, computer modeling, and 3D virtual worlds-and addresses challenges arising from their design and use. The editors' holistic perspective frames these innovations as not only discrete technologies but as flexible learning environments that foster student engagement, participation, and collaboration. Contributors describe possibilities for teaching and learning in these and other cutting-edge areas:

• Working with hypermodels and model-based reasoning
• Using visual representations in teaching abstract concepts
• Designing strategies for learning in virtual worlds
• Supporting net-based collaborative teams
• Integrating innovative learning technologies into schools
• Developing personal learning communities

Designs for Learning Environments of the Future will enhance the work of a wide range of professionals, including researchers and graduate students in the learning and cognitive sciences, and educators in the physical and social sciences.

Over 2 million people are incarcerated in America's prisons and jails, eight times as many since 1975. At current incarceration rates, an African American born in the U.S. today has a 30 per cent chance of spending some time in prison. Mandatory minimum sentencing, parole agencies intent on sending people back to prison, three-strike laws, for-profit prisons, and other changes in the legal system have contributed to this spectacular rise of the general prison population. After overseeing the largest city jail system in the country, Michael Jacobson knows first-hand the inner workings of the corrections system. In Downsizing Prisons, he convincingly argues that mass incarceration will not, as many have claimed, reduce crime nor create more public safety. Simply put, throwing away the key is not the answer. Given the dire budget shortfalls facing most states, there really is no choice: we no longer have the revenue to continue prison expansion while simultaneously supporting education, health care, and lower taxes. Downsizing Prisons examines specific ways that states have begun to transform their prison systems. Jacobson offers practical policy solutions and strategies, including: changing how parole and probation agencies operate, significantly reducing punitive sentencing and technical parole violations, and supporting drug-treatment programs for low-level drug offenders. These policy changes can actually increase public safety as well as save money. As our prison populations swell to record levels, it is clear that the time to reform our prison system has come. Downsizing Prisons offers a clear and persuasive plan of action.

Some two million Americans are in jail or in prison. Except for the occasional expose, what happens to them is hidden from the rest of us. Is it possible to develop and instill a professional ethic for prison personnel that, in partnership with formal regulatory constraints, will mediate relations among officers, staff, and inmates, or are the failures of imprisonment as an ethically-constrained institution so deeply etched into its structure that no professional ethic is possible? The contributors to this volume struggle with this central question and its broader and narrower ramifications. Some argue that despite the problems facing the practice of incarceration as punishment, a professional ethic for prison officers and staff can be constructed and implemented. Others, however, despair of imprisonment and even punishment, and reach instead for alternative ways of healing the personal and communal breaches constituted by crime. The result is a provocative contribution to practical and professional ethics.

A convincing argument that mass incarceration neither reduces crime nor ensures safety Over two million people are incarcerated in America's prisons and jails, eight times as many since 1975.

"Well, I can't believe I'm doing this, but here I go. Into the abyss..."
With these words, Alex Markham begins writing the story of his deceased older brother. David was a star, beloved by many, but understood by few.
Now his story has fallen into the hands of the younger brother who spent his whole life in David's shadow. But for Alex, this is not a tribute. It's a chance to tell the world the real story...the dark story. The one no one knows. The one no one wants to know.
For only Alex knew the real David Markham...the man behind the fame, the booze, and the drugs. But maybe...just maybe...not even Alex knew the real David.
What will ensue as he writes is a journey of discovery...not only of David's life, but of his own as well.

How food industry lobbyists and a small group of scientists have successfully fought government efforts to reduce dangerous levels of sodium in our food.A high-sodium diet is deadly; studies have linked it to high blood pressure, strokes, and heart attacks. It's been estimated that excess sodium in the American diet causes as many as 100,000 deaths deaths and many billions of dollars in avoidable health-care costs each year. And yet salt is everywhere in our diets--in packaged foods, fast foods, and especially meals at table-service restaurants. Why hasn't salt received the sort of public attention and regulatory action that sugar and fat have? In Salt Wars, Michael Jacobson explains how the American food industry and a small group of scientists have successfully fought government efforts to reduce dangerous levels of sodium in our food. Despite an abundance of research going back more than half a century showing that high-sodium diets lead to hypertension and other ills, a few scientists argue the opposite--that American consume a healthy amount of salt and that eating less would increase the risk of cardiovascular disease. This "man bites dog" take on sodium confused consumers and was enthusiastically taken up by food industry lobbyists. Jacobson, a salt wars combatant for more than forty years, explains what science actually says about salt intake and rebuts "sodium skeptics." He discusses what other countries are doing to cut dietary salt, and describes some recent victories in the United States. He advises readers how to reduce salt--warning them against "salt bombs" (Campbell's Chicken Noodle Soup, for example, packs an entire day's worth of sodium in one can)--and calls on them to suit up for the next battle in the salt wars.
