During the first decade of this new millennium, it is estimated that more than €100 billion will be invested in the third generation (3G) Universal Mobile Telecommunications System (UMTS) in Europe. This fact represents an amazing challenge from both a technical and commercial perspective. Written by experts in the field, this book gives a detailed description of the elements in the UMTS network architecture: the User Equipment (UE), the UMTS Radio Access Network (UTRAN) and the core network. The completely new protocols based on the needs of the new Wideband Code Division Multiple Access (WCD |

Sommario/riassunto |
|
Today the United States has one of the highest poverty rates among the world's rich industrial democracies. The Failed Welfare Revolution shows us that things might have turned out differently. During the 1960's and 1970's, policymakers in three presidential administrations tried to replace the nation's existing welfare system with a revolutionary program to guarantee Americans basic economic security. Surprisingly from today's vantage point, guaranteed income plans received broad bipartisan support in the 1960's. One proposal, President Nixon's Family Assistance Plan, nearly passed into law in the 1970's, and President Carter advanced a similar bill a few years later. |

The failure of these proposals marked the federal government's last direct effort to alleviate poverty among the least advantaged and, ironically, sowed the seeds of conservative welfare reform strategies under President Reagan and beyond. This episode has largely vanished from America's collective memory. Here, Brian Steensland tells the whole story for the first time--from why such an unlikely policy idea first developed to the factors that sealed its fate. His account, based on extensive original research in presidential archives, draws on mainstream social science perspectives that emphasize the influence of powerful stakeholder groups and policymaking institutions. But Steensland also shows that some of the most potent obstacles to guaranteed income plans were cultural. Most centrally, by challenging Americans' longstanding distinction between the "deserving" and "undeserving" poor, the plans threatened the nation's cultural, political, and economic status quo. |
