This new interdisciplinary work presents system dynamics as a powerful approach to enable analysts build simulation models of social systems, with a view toward enhancing decision making. Grounded in the feedback perspective of complex systems, the book provides a practical introduction to system dynamics, and covers key concepts such as stocks, flows, and feedback. Societal challenges such as predicting the impact of an emerging infectious disease, estimating population growth, and assessing the capacity of health services to cope with demographic change can all benefit from the application of computer simulation. This text explains important building blocks of the system dynamics approach, including material delays, stock management heuristics, and how to model effects between different systemic elements. Models from epidemiology, health systems, and economics are presented to illuminate important ideas, and the R programming language is used to provide an open-source and interoperable way to build system dynamics models. System Dynamics Modeling with R also describes hands-on techniques that can enhance client confidence in system dynamic models, including model testing, model analysis, and calibration. Developed from the author’s course in system dynamics, this book is written for undergraduate and postgraduate students of management, operations research, computer science, and applied mathematics. Its focus is on the fundamental building blocks of system dynamics models, and its choice of R as a modeling language make it an ideal reference text for those wishing to integrate system dynamics modeling with related data analytic methods and techniques.

In this volume recent advances in the use of modern quantitative models for the analysis of various problems related to the dynamics of social and economic systems are presented. The majority chapters describe tools and techniques of broadly perceived computational intelligence, notably fuzzy logic, evolutionary computation, neural networks and some non-standard probabilistic and statistical analyses. Due to the high complexity of the systems and problems considered, in many situations it is necessary to consider at the same time analytic, topological and statistical aspects and apply appropriate procedures and algorithms. This volume is a direct result of vivid discussions held during the Fifth International Workshop on Dynamics of Social and Economical Systems (DYSES) which was held at Benevento, Italy September 20-25, 2010, as well as a couple of post-workshop meetings and consultations.

Agent-Based Modelling of Social Networks in Labour–Education Market System

Author: Alexander Tarvid

Publisher: Springer

ISBN: 3319265393

Category: Business & Economics

Page: 92

View: 6280

This book covers the modelling of human behaviour in the education and labour markets, which due to their interdependency are viewed as one system. Important factors influencing the decision-making of individuals and firms in this system are discussed. The role of social environment and networks is stressed. The approach of agent-based modelling is presented and compared with standard economic modelling and other simulation techniques in the context of modelling complex adaptive systems. Practical questions in building agent-based models of labour–education market system with social networks are discussed. These questions include modelling the structure of education system and agent behaviour there; modelling and calibrating the labour market without and with firms; generating the social network, defining its behaviour and calibrating it; and embedding the resulting system into a larger model.

From one of the world’s leading data scientists, a landmark tour of the new science of idea flow, offering revolutionary insights into the mysteries of collective intelligence and social influence If the Big Data revolution has a presiding genius, it is MIT’s Alex “Sandy” Pentland. Over years of groundbreaking experiments, he has distilled remarkable discoveries significant enough to become the bedrock of a whole new scientific field: social physics. Humans have more in common with bees than we like to admit: We’re social creatures first and foremost. Our most important habits of action—and most basic notions of common sense—are wired into us through our coordination in social groups. Social physics is about idea flow, the way human social networks spread ideas and transform those ideas into behaviors. Thanks to the millions of digital bread crumbs people leave behind via smartphones, GPS devices, and the Internet, the amount of new information we have about human activity is truly profound. Until now, sociologists have depended on limited data sets and surveys that tell us how people say they think and behave, rather than what they actually do. As a result, we’ve been stuck with the same stale social structures—classes, markets—and a focus on individual actors, data snapshots, and steady states. Pentland shows that, in fact, humans respond much more powerfully to social incentives that involve rewarding others and strengthening the ties that bind than incentives that involve only their own economic self-interest. Pentland and his teams have found that they can study patterns of information exchange in a social network without any knowledge of the actual content of the information and predict with stunning accuracy how productive and effective that network is, whether it’s a business or an entire city. We can maximize a group’s collective intelligence to improve performance and use social incentives to create new organizations and guide them through disruptive change in a way that maximizes the good. At every level of interaction, from small groups to large cities, social networks can be tuned to increase exploration and engagement, thus vastly improving idea flow. Social Physics will change the way we think about how we learn and how our social groups work—and can be made to work better, at every level of society. Pentland leads readers to the edge of the most important revolution in the study of social behavior in a generation, an entirely new way to look at life itself. From the Trade Paperback edition.

Sociophysics: An Introduction

Author: Parongama Sen,Bikas K. Chakrabarti

Publisher: OUP Oxford

ISBN: 0191639451

Category: Science

Page: 320

View: 8231

This book discusses the study and analysis of the physical aspects of social systems and models, inspired by the analogy with familiar models of physical systems and possible applications of statistical physics tools. Unlike the traditional analysis of the physics of macroscopic many-body or condensed matter systems, which is now an established and mature subject, the upsurge in the physical analysis and modelling of social systems, which are clearly many-body dynamical systems, is a recent phenomenon. Though the major developments in sociophysics have taken place only recently, the earliest attempts of proposing "Social Physics" as a discipline are more than one and a half centuries old. Various developments in the mainstream physics of condensed matter systems have inspired and induced the recent growth of sociophysical analysis and models. In spite of the tremendous efforts of many scientists in recent years, the subject is still in its infancy and major challenges are yet to be taken up. An introduction to these challenges is the main motivation for this book.

Social media shatters the barrier to communicate anytime anywhere for people of all walks of life. The publicly available, virtually free information in social media poses a new challenge to consumers who have to discern whether a piece of information published in social media is reliable. For example, it can be difficult to understand the motivations behind a statement passed from one user to another, without knowing the person who originated the message. Additionally, false information can be propagated through social media, resulting in embarrassment or irreversible damages. Provenance data associated with a social media statement can help dispel rumors, clarify opinions, and confirm facts. However, provenance data about social media statements is not readily available to users today. Currently, providing this data to users requires changing the social media infrastructure or offering subscription services. Taking advantage of social media features, research in this nascent field spearheads the search for a way to provide provenance data to social media users, thus leveraging social media itself by mining it for the provenance data. Searching for provenance data reveals an interesting problem space requiring the development and application of new metrics in order to provide meaningful provenance data to social media users. This lecture reviews the current research on information provenance, explores exciting research opportunities to address pressing needs, and shows how data mining can enable a social media user to make informed judgements about statements published in social media.

(R)Evolution studies the adaptation of industrial organisations to the dynamics of the environment by drawing an analogy with evolutionary biology, by extensively studying literature in management science, and by case studies. These investigations have lead to the insight that companies might evolve slower than generally expected; they doubt the effect of reorganizations, as commonly practiced in industry. Additionally, this work proposes the model for the Innovation Impact Point, the model for the Dynamic Adaptation Capability, the model for Collaboration.

Studienarbeit aus dem Jahr 2007 im Fachbereich Soziologie - Methodologie und Methoden, Note: 1,0, Universitat Konstanz (Fachbereich: Soziologie), Veranstaltung: Netzwerkanalyse, 5 Quellen im Literaturverzeichnis, Sprache: Deutsch, Abstract: Diese Arbeit befasst sich mit dem 1993 im American Journal of Sociology erschienenen Aufsatz von John Padgett Robust Action and the rise of the Medici 1400-1434." Die Relevanz dieses Artikels fur das Thema der Netzwerkanalyse ergibt sich schon aus dem Titel des Papers, welcher frei ubersetzt stabile Beziehungen" lauten konnte. Padgett, der an der University of Chicago eine Professur fur Politikwissenschaften inne hat, ist ausserdem auswartiger Professor am Santa Fe Institute, wo er sich sich seit 15 Jahren mit dem Thema: Innovation in Markets - Co-Evolution of State and Market in Renaissance Florence" beschaftigt. In diesen Rahmen ist auch der hier zu behandelnde Aufsatz einzuordnden. Padgett verfolgt mit der Arbeit die Absicht, seine These zu belegen, dass die Medici im Florenz zur Zeit des Ubergangs von Spatmittelalter zur Fruhrenaissance nicht, wie bisher von Geschichtswissenschaftlern vermutet, ihre immense Macht und Bedeutung erlangten, indem sie die eigene Differenz zum bestehenden System der Oligarchen ausbauten und aus ihren unterschiedlichen sozialen Attributen Kapital schlugen, sondern dass sie den Oligarchen auf struktureller Ebene glichen. Sie mussten sich also vielmehr auf einer anderen Ebene von den bisherigen elitaren Strukturen unterscheiden. Wie wir sehen werden, wird diese Ebene durch den Terminus robust action" umrissen. Zum einfacheren Verstandnis wollen wir uns in der Unterteilung dieser Arbeit an die Vorlage halten. Nach einer kurzen Definition des Problems und der verwendeten Begriffe in diesem spezifischen Kontext, widmen wir uns Padgetts Untersuchungen der Sozialstruktur anhand seiner drei verschiedenen Modelle. Diese sind im Einzelnen die Netzwerkanalyse zur Untersuchung der Attributverteilung unt

This book will advance the understanding and application of self-adaptive intelligent systems; therefore it will potentially benefit the long-term goal of replicating certain levels of brain-like intelligence in complex and networked engineering systems. It will provide new approaches for adaptive systems within uncertain environments. This will provide an opportunity to evaluate the strengths and weaknesses of the current state-of-the-art of knowledge, give rise to new research directions, and educate future professionals in this domain. Self-adaptive intelligent systems have wide applications from military security systems to civilian daily life. In this book, different application problems, including pattern recognition, classification, image recovery, and sequence learning, will be presented to show the capability of the proposed systems in learning, memory, and prediction. Therefore, this book will also provide potential new solutions to many real-world applications.
