    Managing a portal of digital web resources by content syndication

    Get PDF
    As users become more accustomed to continuous Internet access, they will have less patience with the offering of disparate resources. A new generation of portals is being designed that aids users in navigating resource space and in processing the data they retrieved. Such portals offer added value by means of content syndication: the effort to have multiple, federated? resources co-operate in order to profit optimally from their synergy. A portal that offers these advantages, however, can only be of lasting value if it is sustainable. We sketch a way to set up and run an organisation that can manage a content syndication portal in a sustainable way.\ud \u

    Space and Collective Identities

    Sowohl IdentitĂ€ts- als auch Raumkonzepte haben in den einzelnen Wissenschaften bereits verschiedene Konjunkturen durchlaufen. Eine intensive Diskussion ĂŒber ihre aktuelle Definition sowie die Möglichkeiten und Grenzen ihrer Anwendung in den Altertumswissenschaften fehlt jedoch bislang weitgehend. Die im Sommer 2009 gegrĂŒndete Cross Sectional Group V (CSG-V) bietet hierfĂŒr einen Kommunikationsraum. FĂŒr einen die Topoi-Areas ĂŒbergreifenden Austausch wurden spezielle Kommunikationsformate etabliert, z. B. ein monatlich stattfindendes Forum, ein Lesezirkel und Seminare. Ziel ist es u. a., auf methodisch- konzeptionellem Wege das Kernproblem der Verbindung von rĂ€umlich verorteter materieller Kultur mit kollektiven IdentitĂ€ten zu untersuchen. HĂ€ufig wurden und werden hier Identifizierungen vorgenommen, die unreflektiert und ideologisch-politisch aufgeladen sind. Ebenso mĂŒssen neue Erkenntnisse aus den Naturwissenschaften methodenkritisch in die Forschung integriert werden, auch um mit den wieder verstĂ€rkt auftretenden biologistischen Vorstellungen angemessen umgehen zu können. Dazu ist eine Auseinandersetzung mit wissenschaftsgeschichtlichen Fragestellungen und zeitgeschichtlichen, auf archĂ€ologischen Orten und archĂ€ologischen Wissensproduktionen basierenden Konstitutionen von IdentitĂ€ten notwendig. Ferner stellen die Erforschung von Kulturtransfer, durch den die Dynamik von IdentitĂ€ten und Raum verdeutlicht wird, sowie von sprachlichen und narrativen IdentitĂ€tsdiskursen, z. B. in Form von Eponymen und Mythen, zentrale Aspekte der Arbeit der CSG-V dar. Aufgrund der Aufgabenstellung der CSG-V werden im Folgenden vor allem der diskutierte Raum- und IdentitĂ€tsbegriff sowie ihre sechs Arbeitskomponenten vorgestellt und erst dann einige Schwerpunktthemen kurz behandelt

    PRIMA: A Model-Based Method for Analyzing Place-Related Information in Disaster Response Processes

    Get PDF
    Processes in disaster response management (DRM) and business processes are similar due to their general structure and goals. Thus, applying workflow management systems (WfMS) is discussed as a promising approach to manage disaster response processes (DRP). However, one main obstacle for realizing the potentials of WfMS in DRM is the lack of methods and tools addressing disaster-specific aspects that exceed the “classical” business context. A particular challenge is posed by the analysis of interdependencies resulting from stationary and mobile activities and resources. Therefore, in this contribution, a novel model-based method for analyzing place-related information is proposed and discussed. The PRIMA method aims at the identification of non-operable activities (and possible remedies) before the execution of an actual DRP stalls and is improvised. Applying the method promises a sound basis for both effective and efficient planning of DRP as well as their successful management by future disaster response WfMS

    Thermophysical Properties of an Fe_(57.75)Ni_(19.25)Mo₁₀C₅B₈ Glass‐Forming Alloy Measured in Microgravity

    Iron‐based metallic glasses are among the lowest‐cost form of amorphous metals and have numerous potential applications, such as wear‐resistant coatings, cutting tools, and gears. There is an increased interest for using this novel alloys as protective coatings and to produce structural elements by additive manufacturing. If an accelerated process development is desired, computer‐based process simulations are nowadays a vital tool. As a consequence, high‐quality measurements of the thermophysical properties in the solid and liquid phases are essential for developing numerical simulation models and suitable processing parameters. Due to the high melt reactivity of liquid metals at high temperatures, measurements using conventional containers are challenging, hence containerless methods have to be used. Herein, the thermophysical properties of an Fe‐based metallic glass‐former have been measured in the liquid phase using the electromagnetic levitator ISS‐EML on‐board the International Space Station (ISS)
