Complex systems science: expert consultation report
Executive SummaryA new programme of research in Complex Systems Science must be initiated by FETThe science of complex systems (CS) is essential to establish rigorous scientific principles on which to develop the future ICT systems that are critical to the well-being, safety and prosperity of Europe and its citizens. As the âICT incubator and pathfinder for new ideas and themes for long-term research in the area of information and communication technologiesâ FET must initiate a significant new programme of research in complex systems science to underpin research and development in ICT. Complex Systems Science is a âblue skyâ research laboratory for R&D in ICT and their applications. In July 2009, ASSYST was given a set of probing questions concerning FET funding for ICT-related complex systems research. This document is based on the CS communityâs response.Complex systems research has made considerable progress and is delivering new scienceSince FET began supporting CS research, considerable progress has been made. Building on previous understanding of concepts such as emergence from interactions, far-from-equilibrium systems, border of chaos and self-organised criticality, recent CS research is now delivering rigorous theory through methods of statistical physics, network theory, and computer simulation. CS research increasingly demands high-throughput data streams and new ICT-based methods of observing and reconstructing, i.e. modelling, the dynamics from those data in areas as diverse as embryogenesis, neuroscience, transport, epidemics, linguistics, meteorology, and robotics. CS research is also beginning to address the problem of engineering robust systems of systems of systems that can adapt to changing environments, including the perplexing problem that ICT systems are too often fragile and non-adaptive.Recommendation: A Programme of Research in Complex Systems Science to Support ICTFundamental theory in Complex Systems Science is needed, but this can only be achieved through real-world applications involving large, heterogeneous, and messy data sets, including people and organisations. A long-term vision is needed. Realistic targets can be set. Fundamental research can be ensured by requiring that teams include mathematicians, computer scientists, physicists and computational social scientists.One research priority is to develop a formalism for multilevel systems of systems of systems, applicable to all areas including biology, economics, security, transportation, robotics, health, agriculture, ecology, and climate change. Another related research priority is a scientific perspective on the integration of the new science with policy and its implementation, including ethical problems related to privacy and equality.A further priority is the need for education in complex systems science. Conventional education continues to be domain-dominated, producing scientists who are for the most part still lacking fundamental knowledge in core areas of mathematics, computation, statistical physics, and social systems. Therefore:1. We recommend that FET fund a new programme of work in complex systems science as essential research for progress in the development of new kinds of ICT systems.2. We have identified the dynamics of multilevel systems as the area in complex systems science requiring a major paradigm shift, beyond which significant scientific progress cannot be made.3. We propose a call requiring: fundamental research in complex systems science; new mathematical and computational formalisms to be developed; involving a large âguinea pigâ organisation; research into policy and its meta-level information dynamics; and that all research staff have interdisciplinary knowledge through an education programme.Tangible outcomes, potential users of the new science, its impact and measures of successUsers include (i) the private and public sectors using ICT to manage complex systems and (ii) researchers in ICT, CSS, and all complex domains. The tangible output of a call will be new knowledge on the nature of complex systems in general, new knowledge of the particular complex system(s) studied, and new knowledge of the fundamental role played by ICT in the research and implementation to create real systems addressing real-world problems. The impact of the call will be seen through new high added-value opportunities in the public and private sectors, new high added-value ICT technologies, and new high added-value science to support innovation in ICT research and development. The measure of success will be through the delivery of these high added-value outcomes, and new science to better understand failures
Finite-key security analysis for multilevel quantum key distribution
We present a detailed security analysis of a d-dimensional quantum key
distribution protocol based on two and three mutually unbiased bases (MUBs)
both in an asymptotic and finite key length scenario. The finite secret key
rates are calculated as a function of the length of the sifted key by (i)
generalizing the uncertainly relation-based insight from BB84 to any d-level
2-MUB QKD protocol and (ii) by adopting recent advances in the second-order
asymptotics for finite block length quantum coding (for both d-level 2- and
3-MUB QKD protocols). Since the finite and asymptotic secret key rates increase
with d and the number of MUBs (together with the tolerable threshold) such QKD
schemes could in principle offer an important advantage over BB84. We discuss
the possibility of an experimental realization of the 3-MUB QKD protocol with
the orbital angular momentum degrees of freedom of photons.Comment: v4: close to the published versio

Looking for Alternatives in Global Governance: Why Multi-Level Health Governance Is Not the Answer for Poverty Reduction
From Normative Power to Great Power Politics: Change in the European Union's Foreign Policy Identity. Jean Monnet/Robert Schuman Paper Series. Vol. 5, No. 14 June 2008
[From the Introduction] At the beginning of the twenty-first century, one of the most significant developments in international relations is the important and growing role of the European Union (EU) as a global player in contemporary world politics. But what exactly is that role, how does the EU manage its relations with the external world and what identity does the EU wish to present to that world? In other words, what is the foreign policy identity of the EU? These are questions that analysts and scholars have grappled with since the formal creation of the EU at Maastricht in 1991 (Treaty on European Union). The EU has worked very carefully to foster a specific type of international identity. It is generally seen and theorized as a leader in the promotion of international peace and humanitarian issues. The EU presents itself as a normative force in world politics. It has customarily placed overriding emphasis on international law, democracy, human rights, international institutions, and multilateralism in its foreign policy, while eschewing a foreign policy based on traditional national interests and material gain. The EU has, in fact, explicitly and formally announced these normative goals for its foreign policymaking in the second pillar of the Treaty on European Union, more commonly known as the CFSP (Common Foreign and Security Policy). But in a world that has become markedly more perilous since September 11, 2001, many Europeans consider U.S. unilateralism as dangerous as the putative terrorist activity it is attempting to halt. As a result, are we seeing the foreign policy identity of the EU begin to change? Does the EU see itself as a possible balance against the primacy of the United States? In other words, does the EU show signs of transforming to a more traditional foreign policy orientation; one based on traditional great power politics and geared towards ensuring the most basic of state interests: survival, security and power? This paper will investigate this transforming foreign policy identity of the EU by seeking to answer the following questions: If the EUâs foreign policy identity is indeed changing, then how is it changing, what is it becoming, and most importantly, what is causing it to change? I will argue that the EUâs foreign policy identity is changing from a normative power to an identity based more closely on a great power politics model; and that the influence of epistemic communities or knowledge based networks is a primary catalyst for this change
Do employeesâ generational cohorts influence corporate venturing? A multilevel analysis
Organizations are facing an interesting phenomenon in the composition of theirworkforce: the concurrence of multiple age generations that demand suitablestrategies regarding work design, job satisfaction, and incentives. Ongoingentrepreneurship and strategic management debates require a betterunderstanding of the relationship between workplace generational cohortsâconfigurations and organizational performance. We propose a conceptual modelfor understanding how a diversified workforce influences some determinants(i.e., employeesâ human capital and attitudes, organizational climate, andenvironmental conditions) of entrepreneurial organizationsâ outcomes (i.e.,corporate venturing). Our framework offers insights into corporate venturingdeterminants for three generational cohorts: Baby Boomers, Generation X, andGeneration Y. Using a sample of 20,256 employees across 28 countries, ourfindings lend support to the positive effect of individual and organizationaldeterminants on corporate venturing, as well as how these effects are reinforcedper generational cohort. Specifically, our results show that younger generations(millennials) have more propensity to be involved in corporate venturingactivities. This study also contributes to thought-provoking implications forentrepreneurial organizational leaders who manage employees from differentgenerations
