Growing artificial societies : social science from the bottom up by Joshua M Epstein( Book )
16 editions published between 1995 and 1997 in English and held by 532 libraries worldwide
How do social structures and group behaviors arise from the interaction of individuals? Growing Artificial Societies approaches this question with cutting-edge computer simulation techniques. Fundamental collective behaviors such as group formation, cultural transmission, combat, and trade are seen to "emerge" from the interaction of individual agents following a few simple rules. In their program, named Sugarscape, Epstein and Axtell begin the development of a "bottom up" social science that is capturing the attention of researchers and commentators alike. The study is part of the 2050 Project, a joint venture of the Santa Fe Institute, the World Resources Institute, and the Brookings Institution. The project is an international effort to identify conditions for a sustainable global system in the next century and to design policies to help achieve such a system. Growing Artificial Societies is also available on CD-ROM, which includes about 50 animations that develop the scenarios described in the text. Copublished with the Brookings Institution

Innovation from a computational social science perspective : analyses and models by Randy M Casstevens( Book )
1 edition published in 2013 in English and held by 2 libraries worldwide
Innovation processes are critical for preserving and improving our standard of living. While innovation has been studied by many disciplines, the focus has been on qualitative measures that are specific to a single technological domain. I adopt a quantitative approach to investigate underlying regularities that generalize across multiple domains. I use a novel approach to better understand the innovation process by combining computational models with empirical data on software development, on one hand, and the evolution of the English lexicon on the other. Innovation can be viewed as the recombination and mutation of existing building blocks. I focus on how building blocks are used to generate innovations. The building blocks are pieces of code (e.g., functions or objects) for the software development data and words for the written language. These data lie at extremes of time scales: innovation occurring over the course of a few days or a week in the case of software while language evolution occurs over decades or centuries. This allows the examination of innovation processes that range from highly-constrained to completely open-ended. Computational methods reinforce the findings from the data analyses and permit exploration of the general features of innovation processes through the construction of abstract models
Agent-based modeling in intelligence analysis by Aaron B Frank( Book )
1 edition published in 2012 in English and held by 2 libraries worldwide
The United States Intelligence Community (IC) was born out of the experiences and organization of the Office of Strategic Services during World War II and became a permanent fixture of the national security establishment with the passage of the National Security Act of 1947. Since its inception, there has been a strong fascination with the secret aspects of its work, particularly with respect to the clandestine collection of information and covert efforts to influence foreign governments, and to undermine rival intelligence services. By comparison, intelligence analysis, specifically the ways in which intelligence professionals develop and present assessments about the international system to policy makers, has been relatively ignored. As a result, intelligence analysis has remained largely under-theorized within the study of international relations, despite its prominent role in strategic thinking--only receiving significant attention in the aftermath of perceived failures. Understanding intelligence analysis is made more complex as new technologies affect analysts' access to new sources and methods. The challenge of technological change in intelligence studies has often been approached in one of three ways. New technologies may be seen as the source of new threats and opportunities in the international system, thus falling within the general application of security studies or international relations through threat assessments and estimates. A related, secondary study of technological change is more confined to the IC, pertaining to how new technologies might be exploited for collecting information, deceiving adversaries, and processing data. A third consideration of technology within the IC is largely concerned with organizational structure and processes, particularly as they relate to the sharing and securing of information within and between the communities. This study considers a fourth perspective of technological change with in the IC by examining how new technologies affect the tradecraft of analysis itself. In doing so, several perspectives are considered in order to understand how Agent-Based Modeling (ABM) can transform the dominant analytic paradigms that guide how intelligence analysis is currently practiced. While the majority of intelligence studies are empirical in nature, this project develops and advances a normative theory of intelligence analysis that argues for the careful consideration, development, and implementation of a model-centric analytic tradecraft, particularly for the production of strategic intelligence. Rather than focus on prior cases of intelligence failures in order to demonstrate how intelligence analysts, collectors, managers, and policy makers have erred in the past, this project provides theoretical arguments in favor of establishing a new analytic tradecraft and demonstrates, if only in a rudimentary fashion, what this new approach may look like in practice. In this study, several persistent debates within intelligence studies, familiar to a small group of scholars and theoretically minded professionals, are reimagined in light of the challenges and opportunities that new modeling and simulation capabilities provide. At its simplest, most conservative application, ABM extends the ongoing development of Structured Analytic Techniques (SATs), the centerpiece of contemporary analytic tradecraft. At the maximum, ABMs can reframe analytic practice, synthesizing the longstanding and opposing views as to whether intelligence analysis is an art or a science, and in the process transform the most challenging and interesting aspect of the intelligence profession--the relationship between intelligence producers and consumers
