Book Description
``Spectroscopy of Crystals Containing Rare Earth Ions'' contains chapters on some key problems selected from a broad range of spectroscopic studies of RE-activated solids including both crystalline and glassy materials. Progress in crystal field theory is surveyed, an area which is basic to our understanding of the energy levels. The treatment of dynamical properties includes studies of coherence phenomena in isolated ions, energy transfer between ions and co-operative phenomena associated with ion-ion and ion-lattice interactions. In addition, the role of electron spins and nuclear spins is studied by light scattering and double resonance techniques. The presence of inhomogeneous broadening of spectral lines is observed and studied in many contexts, leading to new insights into general problems of the disordered state. Considerable attention is devoted to describing new experimental techniques whose development is of prime importance for progress in the spectroscopy of RE-activated solids. Many of these rely on the development and application of tunable lasers. At the moment this is a very active field of spectroscopy with more exciting developments likely to occur in the future.

Book Description
Problems and Perspectives- Studies in the Modern French Language looks at a number of interesting or problematic areas in the phonology, morphology, syntax and lexis of the French language and encourages the reader to think critically about different ways of approaching, describing and explaining these issues or data. The book is divided into two parts- the first section is a preliminary to, and contextualises, the discussion of the more specialised topics of the second part. Part two presents problematic and controversial areas in the description and analysis of the contemporary language. Where appropriate historical and sociolinguistic issues are also integrated into the discussion of modern French. Aimed primarily at advanced students and researchers in French linguistics, the introductory sections of part one also make this book accessible to undergraduates beginning their study of French linguistics, and to less specialised readers.

Book Description
Like our ancestors, we must do our best to survive, form friendships, win respect, attract mates, and care for our families. In the 21st century, however, the threats to our survival are sometimes hidden. This book presents evolutionary science-based advice for fending off our modern attackers and learning how to be happy in the modern world.

Book Description
Many distinct, controvertial issues are to be found within the labyrinthine twists and turns of the problem of evil. For philosophers of the seventeenth and early eighteenth centures, evil presented a challenge to the consistency and rationality of the world-picture disclosed by the new way of ideas. In dealing with this challenge, however, philosophers were also concerned with their positions in the theological debates about original sin, free will, and justification that were the legacy of the Protestant Reformation to European intellectual life. Emerging from a conference on the problem of evil in the early modern period held at the University of Toronto in 1999, the papers in this collection represent some of the best original work being done today on the theodicies of such early modern philosophers as Leibniz, Suarez, Spinoza, Malebranche, and Pierre Bayle.

Book Description
This book identifies and discusses research directions, challenges and achievements in contemporary geography. It also documents the most current theoretical and methodological considerations undertaken by scientists representing various sub-disciplines of geography with particular reference to human geography. It was assumed that the thematic structure of the currently active International Geographical Union (IGU) problem commissions corresponds to the most relevant and current research directions in geography. Reflecting this assumption, the book consists of 14 chapters contributed by geographers representing 14 problem commissions of the IGU, which allows us to examine geography from different perspectives and to provide the reader with a complete overview of contemporary research issues in human geography. The first part discusses contemporary research problems and issues related to scientific methodology and achievements of selected geographical sub-disciplines, including urban geography, agricultural geography, transport geography, and political geography, among others. The second part focuses on the interdisciplinarity of geography and the topics of global dimension undertaken by geographers such as global change, GIS and geospatial technology, marginalization, and environmental change. This part also discusses the internal relations between geographical specializations and their links with other related sciences, including geology, sociology, and economics. The third part discusses the holistic approaches of geography applied to particular regions, territories, or conditions (Africa, costal systems, geomorphology and local development).
