The RAND Corporation’s Collection Operations Model (COM) is a stochastic, agent-based simulation tool designed to support the analysis of command, control, communications, intelligence, surveillance, and reconnaissance (C3ISR) processes and scenarios. Written for the System Effectiveness Analysis Simulation modeling environment, the COM is used to study processes that require the real-time interaction of many players and to answer questions about force mix, system effectiveness, concepts of operations, basing and logistics, and capability-based assessment. It can represent thousands of a

Discrete optimization problems are everywhere, from traditional operations research planning problems, such as scheduling, facility location, and network design; to computer science problems in databases; to advertising issues in viral marketing. Yet most such problems are NP-hard. Thus unless P = NP, there are no efficient algorithms to find optimal solutions to such problems. This book shows how to design approximation algorithms: efficient algorithms that find provably near-optimal solutions. The book is organized around central algorithmic techniques for designing approximation algorithms,

Hailed by Bruce Sterling as “a political activist, gizmo freak, junk collector, programmer, entrepreneur, and all-around Renaissance geek,” the Internet’s favorite high-tech culture maven is celebrated with the first collection of his infamous articles, essays, and polemics. Irreverently championing free speech and universal access to information—even if it’s just a free download of the newest Britney Spears MP3—he leads off with a mutinous talk given at Microsoft on digital rights management, insisting that they stop treating their customers as criminals.

The steadily increasing popularity of tourism in both developed and developing countries has led to an intriguing debate around its role in sustainable development. In this concise overview, Johan Viljoen begins by defining rural tourism and examining international trends in rural tourism development in both developed and developing contexts.He then examines post-1994 tourism policy development in South Africa and shows how internal changes and the massive increase in international tourists visiting South Africa are shaping the development of niche tourism types.A useful primer for anyone work

It is an open question whether a reprint of Dr. Benjamin Trum-bull's History of Connecticut should be modernized even by an introduction. It stands to-day, as it has stood for a century, the most careful, minute, and conscientious chronicle of the colonial history of the State which has ever been written; and it is safe to say that the future historian will, like his predecessors, make numerous citations from this old standard history, and will take the risk-always a dangerous one-of omitting some of the mi-nute details which its venerable author has so carefully recorded.

Policymakers have become increasingly concerned in recent years about the possibility of future maritime terrorist attacks. Though the historical occurrence of such attacks has been limited, recognition that maritime vessels and facilities may be particularly vulnerable to terrorism has galvanized concerns. In addition, some plausible maritime attacks could have very significant consequences, in the form of mass casualties, severe property damage, and attendant disruption of commerce. Understanding the nature of maritime terrorism risk requires an investigation of threats, vulnerabilities, and

Although much of the growing digital economy rests on the Internet and World Wide Web, which in turn rest on information technology standards, it is unclear how much longer the current momentum can be sustained absent new standards. To discover whether today’s standards processes are adequate, where they are taking the industry, and whether government intervention will be required to address systemic failures in their development, RAND undertook five case studies. So far, it seems, the current standards process remains basically healthy, with various consortia taking up the reins of the
