In this book we will propose new interdisciplinary directions for the study of global and regional problems and the interactions between these two scales. Today contemplating and addressing global and regional problems are bread and butter activities for many professionals interested in ‘international’ matters broadly conceived: academic analysts in several disciplines and fields, practisin…
Understanding how users behave when they connect to social networking sites creates opportunities for better interface design, richer studies of social interactions, and improved design of content distribution systems. In this paper, we present a first of a kind analysis of user workloads in on- line social networks. Our study is based on detailed click- stream data, collected over a 12-day pe…

Wireless networking is widely used in everybody’s daily lives. Nevertheless, not everyone has considered the reasons for such increasing utilization and nor have they understood the consequences. In this introduction, we provide a brief background regarding wireless networking evolution and the main scenarios where these networks are currently deployed.
In this paper, we survey recent work on peer-to-peer systems, and venture some opinions about future requirements for research. The paper is a survey to support the tutorial at the Networks 2002 Conference and is therefore neither complete, nor likely to be up-to-date by the time you are reading this, since the topic was extremely fast- evolving at the time of writing. Instead, we try to bring …

This paper proposes a theoretical framework as a foundation for building online communities of practice when a suite of social networking applications referred to as collective intelligence tools are utilized to develop a product or solutions to a problem. Drawing on recent developments in Web 2.0 tools, research on communities of practice and relevant theories of learning, and the authors own…

Markets, technologies, and policies constantly evolve at different levels in various countries, and this has led us to analyse these aspects as the drivers of energy policies. All have a policy and regulatory impact on market structures, which further stimulates technological development. It is noteworthy that the causes of the energy transition may either stem from the state or from market for…
