This book highlights the attention that policymakers, activists, and the public should pay to internal migration. Although prominent research has analyzed particular types of internal migration, especially urbanization and internally displaced persons (IDPs), the narrow scope of existing studies cannot capture the overlaps of motivation and circumstances that pose serious policy dilemmas. The book is distinctive in examining the full range of modes and motives of internal migration: state-sponsored or unsponsored, coerced or voluntary, land-seeking or market-seeking, urban or rural, and so on. While approaching internal migration holistically, it also emphasizes how it is distinct from international migrations, especially the central role of the state, whose internal divisions and defensive reactions to challenges often play decisive roles in governing migration. The writing style is geared towards accessibility, making it appropriate for college- and graduate-level students as well as the broader public.

Classical and Quantum Mechanics of Noncentral Potentials A Survey of Two-Dimensional Systems

English | PDF | 1998 | 222 Pages | ISBN : 3662113279 | 18.6 MB
Non-central forces have a wide variety of applications in classical and quantum mechanics as demonstrated in this book. The author emphasizes the study of time-dependent potentials, predominantly in two dimensions, without neglecting the quite well understood time-independent case. The construction of invariants in the classical case and the study of solutions to Schrödinger’s equation, as well as a detailed presentation of various mathematical techniques are of main concern to the author. The book addresses theoretical physicists and mathematicians, but it will also be useful for electrical and mechanical engineers.
