This special issue examines the underlying assumptions of the ""A Nation At Risk"" report, the context within which the Commission's work was situated, and the effects of the report in improving teaching and learning, as well as the performance of the public educational system. The purpose is to address three broad questions: Was America's education system really putting the nation at risk in the early 1980s? What is the legacy of ""A Nation At Risk""? Given our current knowledge on education and human development, the report's overall concern is restated: What risks and opportunities lay before the nation today, and how will they affect the notion of a "learning society" and our public education system? Taken as a whole, the seven articles address the three broad issues identified regarding the past, current, and future of educational reform in the United States.

This book provides an accessible introduction to the variational formulation of Lagrangian and Hamiltonian mechanics, with a novel emphasis on global descriptions of the dynamics, which is a significant conceptual departure from more traditional approaches based on the use of local coordinates on the configuration manifold. In particular, we introduce a general methodology for obtaining globally valid equations of motion on configuration manifolds that are Lie groups, homogeneous spaces, and embedded manifolds, thereby avoiding the difficulties associated with coordinate singularities. The material is presented in an approachable fashion by considering concrete configuration manifolds of increasing complexity, which then motivates and naturally leads to the more general formulation that follows. Understanding of the material is enhanced by numerous in-depth examples throughout the book, culminating in non-trivial applications involving multi-body systems. This book is written for a general audience of mathematicians, engineers, and physicists with a basic knowledge of mechanics. Some basic background in differential geometry is helpful, but not essential, as the relevant concepts are introduced in the book, thereby making the material accessible to a broad audience, and suitable for either self-study or as the basis for a graduate course in applied mathematics, engineering, or physics.

In the wake of the tragedy and destruction that came with Hurricane Katrina in 2005, public schools in New Orleans became part of an almost unthinkable experiment--eliminating the traditional public education system and completely replacing it with charter schools and school choice. Fifteen years later, the results have been remarkable, and the complex lessons learned should alter the way we think about American education. New Orleans became the first US city ever to adopt a school system based on the principles of markets and economics. When the state took over all of the city's public schools, it turned them over to non-profit charter school managers accountable under performance-based contracts. Students were no longer obligated to attend a specific school based upon their address, allowing families to act like consumers and choose schools in any neighborhood. The teacher union contract, tenure, and certification rules were eliminated, giving schools autonomy and control to hire and fire as they pleased. In Charter School City, Douglas N. Harris provides an inside look at how and why these reform decisions were made and offers many surprising findings from one of the most extensive and rigorous evaluations of a district school reform ever conducted. Through close examination of the results, Harris finds that this unprecedented experiment was a noteworthy success on almost every measurable student outcome. But, as Harris shows, New Orleans was uniquely situated for these reforms to work well and that this market-based reform still required some specific and active roles for government. Letting free markets rule on their own without government involvement will not generate the kinds of changes their advocates suggest. Combining the evidence from New Orleans with that from other cities, Harris draws out the broader lessons of this unprecedented reform effort. At a time when charter school debates are more based on ideology than data, this book is a powerful, evidence-based, and in-depth look at how we can rethink the roles for governments, markets, and non-profit organizations in education to ensure that America's schools and fulfill their potential for all students.

Advances in our understanding of biological mechanisms have frequently been associated with the development of new techniques. In situ hybridization is a classic case of just such an advance. The technique effectively combines histochemistry with molecular biology and enables the rapid analysis of the distribution of RNA, or DNA, in the tissues. The information gained from this has caused something of a revolution in our understanding of developmental biology, since a fundamental aspect of development is the spatial and temporal expression of genes. In addition the technique has found application in the field of medicine, where it is giving new insights into the functioning of healthy tissues and the diagnosis and study of diseases. This book brings together contributions from leaders in the application of this technique and will help the reader review and be guided through the various options and variations of the technique.

This undergraduate textbook offers a unique introduction to steady flight and performance for fixed-wing aircraft from a twenty-first-century flight systems perspective. Emphasizing the interplay between mathematics and engineering, it fully explains the fundamentals of aircraft flight and develops the basic algebraic equations needed to obtain the conditions for gliding flight, level flight, climbing and descending flight, and turning flight. It covers every aspect of flight performance, including maximum and minimum air speed, maximum climb rate, minimum turn radius, flight ceiling, maximum range, and maximum endurance.

"Steady Aircraft Flight and Performance" features in-depth case studies of an executive jet and a general aviation propeller-driven aircraft, and uses MATLAB to compute and illustrate numerous flight performance measures and flight envelopes for each. Requiring only sophomore-level calculus and physics, it also includes a section on translational flight dynamics that makes a clear connection between steady flight and flight dynamics, thereby providing a bridge to further study.Offers the best introduction to steady aircraft flight and performance Provides a comprehensive treatment of the full range of steady flight conditions Covers steady flight performance and flight envelopes, including maximum and minimum air speed, maximum climb rate, minimum turn radius, and flight ceiling Uses mathematics and engineering to explain aircraft flight Features case studies of actual aircraft, illustrated using MATLAB Seamlessly bridges steady flight and translational flight dynamics

Medicines are the most common form of treatment for those with mental health problems worldwide. "Medicines Management in Mental Health Care" is the first detailed evidence-based medicines management text for mental health practitioners in the UK.
"Medicines Management in Mental Health Care" is divided into two parts. Part one provides mental health nurses and other mental health workers with a detailed understanding of the evidence-base for medicines management covering subjects including psychotropic medication and co-morbidity. Part two addresses the practical implications for clinical practice and provides vital guidance on prescribing and medicines management, working with service users, treatment adherence, evaluation skills and problem solving as well as specific advice relating to the realities of practice.
"Medicines Management in Mental Health Care" is an essential resource for mental health nurses and mental health practitioners.
- Discusses evidence-based interventions
- Outlines the main types of medicines offered
- Discusses co-morbidity
- Outlines a model of medicines management
- Discusses good prescribing practice
