    Research aimed at helping to solve pressing societal problems must meet specific quality requirements: The knowledge it produces must not only be sound but also useable. This is particularly true of research that aims at bringing specific knowledge to bear on policy issues relating to sustainable development. This guide provides detailed actor-specific requirements profiles for this type of “policy relevant sustainability research.” This guide is aimed at research funding agencies and contracting entities, researchers themselves and policymakers1 who participate directly in the research process. It can be used both for cases where the research funding agency/contracting entity and the policymaker are different institutions or where they are identical. However, policy consulting by specialized agencies that do not perform original research is not addressed. The requirements profiles serve two functions. First of all, they should function as a guide for the three stakeholder groups, aiding them in their efforts to increase and ensure the quality of research processes and research outcomes. And, secondly, they should improve the reflexive communication among stakeholders regarding the means and the goals of research... The results presented here are part of a research and development project (Research Code Number: 3711 11 701) funded by the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU) and the German Federal Environment Agency (UBA). The project was carried out by the Institute for Social-Ecological Research (ISOE, project management), the Institute for Ecological Economy Research and the Environmental Policy Research Center for of the Freie Universität Berlin (FFU) (project duration: 09/2011-01/2013). The aim of the project was to develop concepts that can be used to increase the relevance of sustainability research for the design of environmental policy in Germany. In addition to the requirements profiles for a policy relevant sustainability research presented in this guide, recommendations, based on empirical studies, have been developed regarding how the coordination between different government departments with respect to funding such research can be optimized. The project's final report will be available starting March 2013 from the UBA.orschung, die einen unmittelbaren Beitrag zur Lösung drängender gesellschaft-licher Probleme leisten will, muss sich besonderen Qualitätsanforderungen stellen: Sie soll nicht nur gesichertes, sondern auch anwendbares Wissen bereithalten.

Die hier vorgestellten Ergebnisse wurden im Rahmen eines vom Bundesministe-rium für Umwelt, Naturschutz und Reaktorsicherheit (BMU) und dem Umwelt-bundesamt (UBA) finanzierten Forschungs- und Entwicklungsvorhabens erarbeitet (Forschungskennzahl 3711 11 701). Das Vorhaben wurde vom Institut für sozial-ökologische Forschung (ISOE, Vorhabenleitung), dem Institut für ökologische Wirt-schaftsforschung (IÖW) und dem Forschungszentrum für Umweltpolitik der Freien Universität Berlin (FFU) durchgeführt (Laufzeit: 09/2011–01/2013). Ziel des Vorhabens war es, Konzepte zu entwickeln, mit deren Hilfe die Relevanz der Nachhaltigkeitsforschung für die Gestaltung von Umweltpolitik in Deutschland erhöht werden kann. Neben dem hier vorgestellten Anforderungsprofil für eine politikrelevante Nachhaltigkeitsforschung wurden auf Basis empirischer Erhebun-gen auch Empfehlungen erarbeitet, wie die Abstimmung zwischen verschiedenen Bundesressorts bei der Förderung von Nachhaltigkeitsforschung optimiert werden kann. Der Abschlussbericht des Vorhabens kann ab März 2013 über das UBA bezo-gen werden

    Ledoux-Convection in Protoneutron Stars --- a Clue to Supernova Nucleosynthesis?

    Get PDF
    Two-dimensional hydrodynamical simulations of the deleptonization of a newly formed neutron star were performed. Driven by negative lepton fraction and entropy gradients, convection starts near the neutrinosphere about 20-30 ms after core bounce, but moves deeper into the protoneutron star, and after about one second the whole protoneutron star is convective. The deleptonization of the star proceeds much faster than in the corresponding spherically symmetrical model because the lepton flux and the neutrino luminosities increase by up to a factor of two. The convection below the neutrinosphere raises the neutrinospheric temperatures and mean energies of the emitted neutrinos by 10-20%. This can have important implications for the supernova explosion mechanism and changes the detectable neutrino signal from the Kelvin-Helmholtz cooling of the protoneutron star. In particular, the enhanced electron neutrino flux relative to the electron antineutrino flux during the early post-bounce evolution might solve the overproduction problem of certain elements in the neutrino-heated ejecta in models of type-II supernova explosions.Comment: 17 pages, LaTeX, 8 postscript figures, uses epsf.sty.

    Partial Covering Interpretation of the X-Ray Spectrum of the NLS1 1H 0707-495

    Full text link
    The X-ray spectrum of 1H 0707-495 obtained with XMM-Newton showing a deep flux drop at ~7 keV (Boller et al. 2002) is studied based on the partial covering concept. The previously inferred extreme iron overabundance can be reduced down to ~3x solar if the hard component gradually steepens at high energies. The spectral shape supports that 1H 0707-495 is an AGN analogue of the galactic black-hole binaries in the soft state. Interpreting the soft excess as the emission from an optically-thick disk, the minimum black hole mass M is estimated to be 2 x 10^6 solar masses from the intrinsic luminosity corrected for partial covering. Based on the slim disk model, the observed disk temperature implies that the luminosity is close to the Eddington limit. The rapid and large flux variations with little change in the spectral shape can also be explained, if not all, as due to changes in the partial covering fraction. Partial covering may account for the large variability characteristics of NLS1.Comment: Accepted for publication in PASJ (2004). 9 page

    Capital Mobility for Developing Countries May Not Be So High

    Get PDF
    International capital flows to developing countries have taken on considerable policy importance in recent years. There is disagreement, however, about whether financial capital mobility has become so high that developing countries have little ability to sterilize capital flows. This paper reviews several popular methods of estimating the degree of capital mobility for developing countries and shows that they are subject to potentially important upward biases due to inappropriate assumptions concerning the roles of domestic inflation and sterilization. Corrections for these factors can cut estimates of capital mobility by one half or more.sterilization; capital mobility; developing countries

    Standardization: Bridging the Gap Between Economic and Social Theory

    Get PDF
    This article examines the dynamics of inter- and intra-firm networks in technical standard setting initiatives, and how complex social networks align in these initiatives. Specifically, we argue that in standardization, complex economic and social interactions are blended. In standardization activities, firm behavior and the behavior of individuals within firms is best explained through an integration of social, political, and economic perspectives. In this article we use two main bodies of theory. First, we draw on the economic literature on standard setting and alliance formation. Second we use social network theory to complement economic arguments. In this paper we integrate streams of literature on the creation and diffusion of technical standards from industrial organization economics, strategic management, and innovation economics with recent literature concerning the social construction of technology in order to analyze the process of standard setting. We develop our arguments with the help of three in-depth case studies of standardization initiatives in the telecommunications industry. Two case studies are in the realm of telecommunications infrastructure. The third case study analyzes the standardization of a wireless data link. The cases can be characterized as examples of the successful creation of both de facto and de jure standards

    Hybrid waveguide-bulk multi-path interferometer with switchable amplitude and phase

    Full text link
    We design and realise a hybrid interferometer consisting of three paths based on integrated as well as on bulk optical components. This hybrid construction offers a good compromise between stability and footprint on one side and means of intervention on the other. As experimentally verified by the absence of higher-order interferences, amplitude and phase can be manipulated in all paths independently. In conjunction with single photons, the setup can, therefore, be applied for fundamental investigations on quantum mechanics.Comment: accepted in APL Photonic
