'Diese Arbeit wendet Konzepte der Sozialwissenschaften auf die Entwicklung der Telekommunikation Großbritanniens vor dem Ersten Weltkrieg an. Betrachtet werden die gesellschaftliche Prägung der Technologie, soziale Netzwerke und die Unterscheidung zwischen kurz- und langfristigen Effekten. Zwei Fallstudien mit Bezug zur Telekommunikation im Großbritannien des 19. Jahrhunderts - die telegraphische Verbindung nach Indien und das Telefon - werden dann mithilfe dieser Konzepte untersucht. Dabei wird behauptet, dass Kommunikationsnetze aus bestehenden sozialen bzw. geschäftlichen Netzwerken entstehen, die wiederum frühere Kommunikations- und Transportnetze reflektieren, und dass die wichtigste sofortige Wirkung eines neuen Kommunikationsmittels der zunehmende Informationsaustausch zwischen existierenden Kontakten ist, während sich auf lange Sicht neue Praktiken entwickeln.'

Agent-based modelling in economics Lynne Hamill and Nigel Gilbert, Centre for Research in Social Simulation (CRESS), University of Surrey, UK New methods of economic modelling have been sought as a result of the global economic downturn in 2008. This unique book highlights the benefits of an agent-based modelling (ABM) approach. It demonstrates how ABM can easily handle complexity: heterogeneous people, households and firms interacting dynamically. Unlike traditional methods, ABM dus not require people or firms to optimise or economic systems to reach equilibrium. ABM offers a way to link micro foundations directly to the macro situation. Key features: -Introduces the concept of agent-based modelling and shows how it differs from existing approaches.-Provides a theoretical and methodological rationale for using ABM in economics, along with practical advice on how to design and create the models.-Each chapter starts with a short summary of the relevant economic theory and then shows how to apply ABM.-Explores both topics covered in basic economics textbooks and current important policy themes; unemployment, exchange rates, banking and environmental issues.-Describes the models in pseudocode, enabling the reader to develop programs in their chosen language.-Supported by a website featuring the NetLogo models described in the book. Agent-based Modelling in Economics provides students and researchers with the skills to design, implement, and analyze agent-based models. Third year undergraduate, master and doctoral students, faculty and professional economists will find this book an invaluable resource.

This book brings together the perspectives of key researchers to explore lessons on social shaping, examining what can be learned from the adoption of mobile devices that can be applied to other, newer, digital technologies. Forecasting the impact of new technology is always difficult. Occasionally demand is underestimated, but more often it is overestimated, and at great cost. Digital technology is unlike anything that has gone before, making it particularly difficult to understand its implications for businesses, public services and society in general. By looking at what has happened in the past and now, and offering methods of using this knowledge to look forward, this book will contribute to reducing expensive forecasting errors in the future. Key reading for all those involved with the future of mobile communications, this book is a valuable resource, particularly for advanced undergraduates and postgraduates on Mobile Technology courses, practitioners, and researchers working in mobile communications, CSCW and HCI.
