In this long memoir that spans eight decades and five continents, Asoka Mendis (Emeritus Professor of Space Physics, University of California, San Diego) recollects the seminal events in his life, as he grew up in Sri Lanka (then Ceylon), did his post-graduate research in England, and subsequently followed a career in research and teaching in the United States following a brief stint in Sri Lanka. Much of the memoir is devoted to copious reflections, that are often triggered by these recollections. A clear thread that runs through the entire narrative is his uncompromising skepticism, and his deep commitment to the application of the empirical or scientific method of investigation (which is ...

This monograph is the first book exclusively devoted to Electrohydrodynamics in Dusty and Dirty Plasmas with extended Electrodynamics and Gravito-Electrodynamics with Electric Mirrors. The book incorporates novel concepts of Electro Cusp-Reconnection and Generalized Critical Ionization Velocities as well as modern concepts of Self-Organization and Chaos. Therefore, the book is special and quite different from the previous edition in the field of plasma physics in terms of scope, object, and approach. The scope of the present work is much broader and much more general with space and laboratory applications, including collisional neutral and partially ionized gases in electric and space-charge fields, thereby accompanying electrical charging, electrification, discharge, ionization and recombination. The book will serve as a text book, text-related or reference book for graduate students, post graduates, and scientists in geo-astro, space, and laboratory plasma physics, electromagnetics and fluid dynamics. In addition, it will be useful for researchers outside the plasma community who wish to obtain new physical insights, aspects, and points of view.
Many scholars, practitioners, and policy-makers in the cultural sector argue that Canadian cultural policy is at a crossroads: that the environment for cultural policy-making has evolved substantially and that traditional rationales for state intervention no longer apply. The concept of cultural citizenship is a relative newcomer to the cultural policy landscape, and offers a potentially compelling alternative rationale for government intervention in the cultural sector. Likewise, the articulation and use of cultural indicators and of governance concepts are also new arrivals, emerging as potentially powerful tools for policy and program development. Accounting for Culture is a unique collection of essays from leading Canadian and international scholars that critically examines cultural citizenship, cultural indicators, and governance in the context of evolving cultural practices and cultural policy-making. It will be of great interest to scholars of cultural policy, communications, cultural studies, and public administration alike.
In May 1998 a hundred renowned scientists from 20 different countries met at the Max-Planck-Institut für Aeronomie to communicate their latest results and ideas in astrophysical and space plasma, as a follow-up to previous similar meetings which were held in Varenna, Abastumai, Potsdam, Toki and Guaruja. The main papers emerging from this meeting are collected in this volume. They deal with fundamental plasma phenomena, particle and radiation processes in astrophysics and space physics as the origin of magnetic activity, the basic mechanisms of particle acceleration and plasma heating common to plasma in galaxies and at the sun as well as in planetary magnetospheres. New observational resul...
