    Heterogeneous Multiagent Architecture for Dynamic Triage of Victims in Emergency Scenarios

    This paper introduces a double multiagent architecture allowing the triage of victims in emergency scenarios and the automatic update of their medical condition. Gathering updated information about the medical condition of victims is critical for designing an optimal evacuation strategy that minimizes the number of casualties in the aftermath of...

    No News In Business Cycles

    This paper uses a structural, large dimensional factor model to evaluate the role of 'News' shocks (shocks with a delayed effect on productivity) in generating the business cycle. The authors find that existing small-scale VECM models are affected by 'Non-fundamentalness' and therefore fail to recover the correct shock and impulse...

    High Availability for Parallel Computers

    Fault tolerance has become an important issue for parallel applications in the last few years. The parallel systems' users want them to be reliable considering two main dimensions, availability and data consistency. Availability can be provided with solutions such as RADIC, a fault tolerant architecture with different protection levels, offering...

    Fiscal Policy, Foresight And The Trade Balance In The U.S

    This paper investigates the effects of fiscal policy on the trade balance using a structural factor model. A fiscal policy shock worsens the trade balance and produces an appreciation of the domestic currency but the effects are quantitatively small. The findings match the theoretical predictions of the standard Mundell-Fleming model,...

    The CHORCH B2Bi Approach: Performing EbBP Choreographies as Distributed BPEL Orchestrations

    Applying choreography and orchestration technology has become a popular method of attacking Business-2-Business integration (B2Bi) challenges like agreement and communication among integration partners, compatibility of interacting processes and distributed computing. ebXML BPSS (ebBP) as dedicated B2Bi choreography standard and WS-BPEL as number one Web service orchestration language are particularly promising...

    Start-up Conditions And The Performance Of Women And Men Controlled Businesses In Manufacturing Industries

    Recent research into the economic performance of women-controlled firms suggests that their underperformance may not be the result of differences in the managerial ability of women as compared to men, and that it may in fact be a consequence of differing levels of start-up resources. Using accounting data, the authors...

    Budget Constrained Expenditure Multipliers

    The authors show that standard expenditure multipliers capture economy-wide effects of new government projects only when financing constraints are not binding. In actual policy making, however, new projects usually need financing. Under liquidity constraints, new projects are subject to two opposite effects: an income effect and a set of spending...

    Constrained Delegation in XML-Based Access Control and Digital Rights Management Standards

    In access control and digital rights management, delegation introduces the ability to decentralize the management of the privileges in a system. Constrained delegation presents a new approach to delegation, where the authority to create a permission and the permission itself is clearly differentiated. This allows the use of delegation for...

    Accounting Conservatism And Firm Investment Efficiency

    Conservatism, through the timelier recognition of losses in the income statement, is expected to increase firm investment efficiency through three main channels: by decreasing the adverse effect of information asymmetries between outside equity holders and managers, facilitating the monitoring of managerial investment decisions; by increasing managerial incentives to abandon poorly...

    Monetary Policy Rules And Inflation Process In Open Emerging Economies: Evidence For 12 New EU Members

    This paper has three objectives. First, it aims at revealing the logic of interest rate setting pursued by monetary authorities of 12 new EU members. Using estimation of an augmented Taylor rule, the authors find that this setting was not always consistent with the official monetary policy. Second, they seek...
