Partial differential equations play a central role in many branches of science and engineering. Therefore it is important to solve problems involving them. One aspect of solving a partial differential equation problem is to show that it is well-posed, i. e. , that it has one and only one solution, and that the solution depends continuously on the data of the problem. Another aspect is to obtain detailed quantitative information about the solution. The traditional method for doing this was to find a representation of the solution as a series or integral of known special functions, and then to evaluate the series or integral by numerical or by asymptotic methods. The shortcoming of this method is that there are relatively few problems for which such representations can be found. Consequently, the traditional method has been replaced by methods for direct solution of problems either numerically or asymptotically. This article is devoted to a particular method, called the "ray method," for the asymptotic solution of problems for linear partial differential equations governing wave propagation. These equations involve a parameter, such as the wavelength. . \, which is small compared to all other lengths in the problem. The ray method is used to construct an asymptotic expansion of the solution which is valid near . . \ = 0, or equivalently for k = 21r I A near infinity.

Despite the rapid surge of new product introductions into the grocery product distribution system, relatively little is known about the process and acceptance criteria of trade buyers. In this work, Edward McLaughlin and Vithala Rao examine the crucial role played by trade buyers, and its place in the success of new product introduction. Their study integrates scholarly research and industry information as it explores the various processes used by manufacturers and trade intermediaries in developing and introducing new products.

The book begins with a background survey of the overall structure of U.S. grocery distribution, along with a discussion of the key participants in new product introduction and their standard operating procedures. A broad framework for analyzing new product introductions is presented, and various methodologies that are useful in the process are explained. This is followed by an account of the extensive research conducted by the authors, focusing on new product acceptance by trade buyers, and drawn from three sources: publicly available information, survey data of actual buyer decisions, and buyer decisions based on hypothetical descriptions of new products. The statistical results on the relative importance of decision criteria are used to develop several management tools, including an expert system. The work concludes with a discussion of the implications of these results for marketing managers, procurement executives, and public policy makers. This book will be an important reference tool for practitioners involved in product procurement, as well as for students of marketing and sales.

This pathbreaking book examines the strategies, successes, and challenges of youth advocacy organizations, highlighting the importance of local contexts for these efforts. Working between social movements and the political establishment, these organizations occupy a special niche in American politics and civil society. They use their position to change local agendas for youth and public perceptions of youth, and work to strengthen local community support systems.
"Between Movement and Establishment" describes how youth advocacy organizations affect change in a fragmented urban policy environment. It considers the different constituencies that organizations target, including public officials and policies, specific service sectors, and community members, and looks at the multiple tactics advocates employ to advance their reform agendas, such as political campaigns, accountability measures, building civic capacity, research, and policy formation. This work further examines the importance of historical, organizational, and political contexts in explaining the strategies, actions, and consequences of advocacy organizations' efforts at the local level, bringing to light what is effective and why.

An innovative approach to winning more profitable sales in the growing professional services industry

In recent years, professional services providers have had to rethink their sales methods and adapt to profound changes in the way clients buy services. In response, "Winning the Professional Services Sale" argues for fundamental changes in the seller's mindset and sales strategies. Rather than pressing the sale, salespeople must help clients buy--the way that works best for each client. This new approach gives buyers what they now want in a services seller: a consultative problem solver, change agent, and solution integrator, all rolled into one. Author Michael McLaughlin presents a strategy for winning new business with a holistic approach to each client relationship. Only by fully understanding a sale from every angle, including its impact on the client's business and career, can salespeople thrive in the new era of the service economy.

American high schools have never been under more pressure to reform: student populations are more diverse than ever, resources are limited, and teachers are expected to teach to high standards for all students. While many reformers look for change at the state or district level, the authors here argue that the most local contexts--schools, departments, and communities--matter the most to how well teachers perform in the classroom and how satisfied they are professionally. Their findings--based on one of the most extensive research projects ever done on secondary teaching--show that departmental cultures play a crucial role in classroom settings and expectations. In the same school, for example, social studies teachers described their students as "apathetic and unwilling to work," while English teachers described the same students as "bright, interesting, and energetic."
With wide-ranging implications for educational practice and policy, this unprecedented look into teacher communities is essential reading for educators, administrators, and all those concerned with U. S. High Schools.

Gettysburg Defining Hours of the Civil War
"Donald W. McLaughlin did not fight in the Battle of Gettysburg, but he spent many years guiding others around these battlefields. It gave him an understanding of the Battlefield and the human dimensions and tragedies of that battle possessed by few other people. Don knew that the many magnificent monuments and memorials in the killing fields of Gettysburg overwhelm the casual visitor and confuse even the serious student. He also understood that the statues and markers themselves may not reveal completely the thoughts and ideas of those who fought here, survived and what they wanted remembered. Such understanding is hard to come by, and for this reason once gathered must be shared, so that others may avoid the mistakes which brought strangers to this beautiful place for the purpose of killing one another. By allowing his personal notes and meticulous research about the monuments and memorials of Gettysburg to be assembled and published, Don McLaughlin has done all of us a tremendous service." - Col. John C. Slaughter, Medical Corps United States Army (retired)
"Don's book is an invaluable resource in locating the numerous monuments that exist on the Gettysburg Battlefield. It's the easiest guide to use, as it has a great index and the numerous maps he drew are excellent. Even more impressive to me, is the fact that the book contains an accurate inscription of every monument on the field " - Eric A. Campbell Park Ranger Gettysburg National Military Park
