Statement of purpose: The purpose of these working papers is to promote the circulation of research results (Research Series) and analytical studies (Documents Series) made within the National Bank of Belgium or presented by external economists in seminars, conferences and conventions organised by the Bank. The aim is therefore to provide a platform for discussion. The opinions expressed are st...

The LEP energy upgrade up to fi =189 GeV has allowed us to extend substantially the potential of searches for new physics. Results on searches for Higgs bosoms and supersymmetric particles obtained by the ALEPH, DELPHI, L3, and OPAL experiments are reported. No evidence of any signal is observed. Therefore, new limits on the Higgs boson masses as well as on the masses of the various supersymmet...

We would like to congratulate Fruchter et al 1 for their ingenious, effective, and minimally invasive way of treating the very challenging condition of bronchopleural fi stulas as reported in a recent issue of CHEST (March 2011). However, because we were cited in their work, we must make a correction. The misunderstanding is that our fi rst publication was a case report of our fi rst patient (5...

A new approach for vague risk analysis based on the ranking of trapezoidal vague sets is proposed. Firstly, a new method for ranking of vague sets is presented. Then, the proposed method is applied to developed a new method for dealing with vague risk analysis problems. This analysis helps us to find out the probability of failure of each components of combustion system, which could be used for...

Society for Risk Analysis (Europe) Conference From the everyday to the extraordinary: challenges for risk analysis and management

This paper proposes a Cross Impact Analysis for supporting critical infrastructures risk analysis. This methodology contributes to decision-makers and planners with analytical tools for modeling complex situations. These features are generally useful in emergency management and particularly within the critical infrastructures scope, where complex scenarios for risk analysis and emergency plans ...

This paper reports the results of a study aimed at understanding and characterising IT management sophistication in small businesses. A multiple-case study approach was therefore used to explore the IT management practices of small businesses. Data collection involved four small-medium chartered accountancy (CA) firms and three IT firms closely associated with the CA industry. The case results ...

The risks posed by management are neither addressed by risk analysis nor included in safety cases. Yet they have been shown to be significant contributors to accidents. This paper argues for more attention to be paid to them and for the development of a risk-analysis method to address them. The paper examines the aspects of management risk that it might cover and offers a set of proposals for i...

This paper discusses some models of Imprecise Probability Theory obtained by propagating uncertainty in risk analysis when some input parameters are stochastic and perfectly observable, while others are either random or deterministic, but the information about them is partial and is represented by possibility distributions. Our knowledge about the probability of events pertaining to the output ...

Digital application marketplaces are increasingly relevant for digital platform owners seeking to reap the benefits of distributing, brokering, and operating applications by third-party developers. Owners of such marketplaces have two vital goals: address the needs of heterogeneous end-users and attract third-party developers. A key element in simultaneously accommodating these goals is value c...
