Mobile and wireless communications are moving towards a new era that will be characterized by the seamless collaboration of heterogeneous systems, the need for high speed communications while on the move and for advanced services with quality guarantees. Recent market research studies show that most of the traffic in the future wireless networks will be produced by mobile multimedia services which are expected to proliferate by the year 2010. On the other hand mobile and wireless communications technology is becoming more and more important in developing countries where people demand fast deployment and low cost for broadband wireless internet services.The objective of this volume is to gather research and development on topics shaping the fourth generation (4G) in mobile and wireless communications and reveal the key trends and enabling technologies for 4G. We envisage 4G wireless communication systems as IP based solution providing integrated services (voice, data, multimedia) regardless of time and end-users? location. 4G technologies will manifest the benefits of the wireless and wired technologies convergence, through enabling a wide range of innovative (both indoor and outdoor) applications. 4G applications will feature premium quality, high security and an affordable cost. The vision, though fantastic, is associated with a host of technical and technological challenges.A great deal of the latter are discussed in the articles of this volume, which aims at providing insights on the research issues and solutions that are directly associated with leading edge 4G technologies and services.Taking into account recent developments in the world of wireless communications we have given emphasis to cover all these technologies and aspects that are considered as cornerstones for achieving the goals set for 4G and that will further boost research and development of next-generation mobile communications.
Tracing Dar es Salaam's rise and fall as an epicentre of Third World revolution, George Roberts explores the connections between the global Cold War, African liberation struggles, and Tanzania's efforts to build a socialist state. Roberts introduces a vibrant cast of politicians, guerrilla leaders, diplomats, journalists, and intellectuals whose trajectories collided in the city. In its cosmopolitan and rumour-filled hotel bars, embassy receptions, and newspaper offices, they grappled with challenges of remaking a world after empire. Yet Dar es Salaam's role on the frontline of the African revolution and its provocative stance towards global geopolitics came at considerable cost. Roberts explains how Tanzania's strident anti-imperialism ultimately drove an authoritarian turn in its socialist project and tighter control over the city's public sphere.

For the entire history of human civilization, gold has enraptured people around the globe. The Nazis was no less enthralled by it, and felt that gold was the solution to funding Hitler's war machine. Gold was also on the mind of FDR across the Atlantic, as he worked with Europe's other leaders to bring the United States and the rest of the world out of a severe depression. FDF was hardly the first head of state to turn to gold in difficult times. Throughout history, it has been the refuge of both nations and people in trouble, working at times when nothing else does. Desperate people can buy a loaf of bread or bribe a border guard. Gold can get desperate nations oil to keep tanks running or munitions to fight a war. If the price is right, there is always someone somewhere willing to buy or sell gold. And it was to become the Nazi's most important medium of exchange during the war. Chasing Gold is the story of how the Nazis attempted to grab Europe’s gold to finance history’s bloodiest war. It is filled with high drama and close escapes, laying bare the palate of human emotions. Walking through the tale are giants of world history, as well as ordinary people called upon to undertake heroic action in an extraordinary time.
At no time in the history of public education has there been such a dramatic discrepancy between accelerated standards and expectations and adequate funding for our schools. Much has been written about how to achieve new expectations in the realm of student achievement. Much has also been written about the need for accountability and the restructuring of how education dollars are spent. Unfortunately, most of the input regarding the need for 'belt-tightening' is unaccompanied by any tangible solutions or suggestions and results only in hollow rhetoric or convenient political sound bytes. Tim Adsit and George Murdock's journey into meaningful avenues for cost-savings in public education is clearly an exception. In this book, readers will find many practical ideas for saving money, which can be readily implemented.
