Since the appearance of computers, numerical methods for discontinuous solutions of quasi-linear hyperbolic systems of partial differential equations have been among the most important research subjects in numerical analysis. The authors have developed a new difference method (named the singularity-separating method) for quasi-linear hyperbolic systems of partial differential equations. Its most important feature is that it possesses a high accuracy even for problems with singularities such as schocks, contact discontinuities, rarefaction waves and detonations. Besides the thorough description of the method itself, its mathematical foundation (stability-convergence theory of difference schemes for initial-boundary-value hyperbolic problems) and its application to supersonic flow around bodies are discussed. Further, the method of lines and its application to blunt body problems and conical flow problems are described in detail. This book should soon be an important working basis for both graduate students and researchers in the field of partial differential equations as well as in mathematical physics.

In the early part of the twentieth century, Buenos Aires erupted from its colonial past as a city in its own right, expressing a unique and vibrant cultural identity.Intersecting Tango engages the city at this key moment, exploring the sweeping changes of 1900-1930 to capture this culture in motion through which Buenos Aires transformed itself into a modern, cosmopolitan city. Taking the reader through a dazzling array of sites, sources, and events, Bergero conveys the city in all its complexity. Drawing on architecture and gendered spaces, photography, newspaper columns, schoolbooks, "high" and "low" literature, private letters, advertising, fashion, and popular music, she illuminates a range of urban social geographies inhabited by the city's defining classes and groups. In mining this vast material, Bergero traces the profound change in social fabric by which these diverse identities evolved, through the processes of modernization and its many dislocations, into a new national identity capable of embodying modernity. In her interdisciplinary study of urban development and cultural encounters with modernity, Bergero leads the reader through the city's emergence, collecting her investigations around the many economic, social, and gender issues remarkably conveyed by the tango, the defining icon of Buenos Aires. Multifaceted and original, Intersecting Tango is as rich and captivating as the dance itself.

This book deconstructs the boundaries between Jewish and Christian cultures while at the same time redefining what it means to be Jewish in relation to Christianity in the twentieth century. Consequently, this analysis reveals the emergence of modern Jewish theologies out of the complex negotiations between Jewish thinkers and their Christian milieu.

In more recent times, the essence of the gatekeeper's role has moved to the 'boundary spanner' - a systems thinker who understands the specific needs and interests of the organization and whose greatest asset is their ability to move across and through the formal and informal features of the modern organization. There are many types of boundaries associated with an organization, for example, horizontal, (function and expertise), vertical (status, hierarchy), geographic, demographic, and stakeholder. Boundaries are "the defining characteristic of organizations and, boundary roles are the link between the environment and the organization" (Aldrich & Herker, 1977) with functions crucial to the effectiveness and success of the organization. Despite being a critical success factor for an organization, beginning in the 1970s, the term - 'boundary spanning' has had an intermittent research history: there has been no systematic body of research that has evolved over time. This book aims to invigorate, excite, and expand the literature on boundary spanning in a diverse range of disciplines such as sociology, organizational psychology, management, medicine, defence, health, social work, and community services. The book serves as the first collection of reviews on boundary spanning in organizations.
