Bruno Staffelbach, Je schneller desto besser? - Zeit im Management, Schweizer Arbeitgeber, Vol. 104 (20), 2009. (Journal Article)
Obwohl in der Ökonomik relativ wenig thematisiert, ist die «Zeit» für den ökonomischen Erfolg in der heutigen Wirtschaft von entscheidender Bedeutung.
Der Schnellere gewinnt den Wettbewerb, nicht der Grössere. Produktiver ist, wer weniger Zeit braucht, und rationalisieren heisst Zeit sparen: Je mehr man gleichzeitig tun kann, desto besser! Wer die Kontrolle über die Zeit hat, hat das Sagen. Im alten Ägypten waren das die Astronomen. Wie wird Zeit in heutigen Organisationen kontrolliert ? Dazu werden zwei System- und zwei Personenprobleme sowie zwei Empfehlungen skizziert. |

During the evolution of a software system, a large amount of information, which is not always directly related to the source code, is produced. Several researchers have provided evidence that the contents of mailing lists represent a valuable source of information: Through e-mails, developers discuss design decisions, ideas, known problems and bugs, etc. which are otherwise not to be found in the system.A technical challenge in this context is how to establish the missing link between free-form e-mails and the system artifacts they refer to. Although the range of approaches is vast, establishing their accuracy remains a problem, as there is no benchmark against which to compare their performance.To overcome this issue, we manually inspected a statistically significant number of e-mails pertaining to the ArgoUML system. Based on this benchmark, we present a variety of lightweight techniques to assign e-mails to software artifacts and measure their effectiveness in terms of precision and recall. |

Stefano Battiston, Jan Lorenz, Frank Schweitzer, Systemic risk in a unifying framework for cascading processes on networks, The European physical journal B, Condensed matter physics, Vol. 71 (4), 2009. (Journal Article)
We introduce a general framework for models of cascade and contagion processes on networks, to identify their commonalities and differences. In particular, models of social and financial cascades, as well as the fiber bundle model, the voter model, and models of epidemic spreading are recovered as special cases. To unify their description, we define the net fragility of a node, which is the difference between its fragility and the threshold that determines its failure. Nodes fail if their net fragility grows above zero and their failure increases the fragility of neighbouring nodes, thus possibly triggering a cascade. In this framework, we identify three classes depending on the way the fragility of a node is increased by the failure of a neighbour. At the microscopic level, we illustrate with specific examples how the failure spreading pattern varies with the node triggering the cascade, depending on its position in the network and its degree. At the macroscopic level, systemic risk is measured as the final fraction of failed nodes, X*, and for each of the three classes we derive a recursive equation to compute its value. The phase diagram of X* as a function of the initial conditions, thus allows for a prediction of the systemic risk as well as a comparison of the three different model classes. We could identify which model class leads to a first-order phase transition in systemic risk, i.e. situations where small changes in the initial conditions determine a global failure. Eventually, we generalize our framework to encompass stochastic contagion models. This indicates the potential for further generalizations. |

Angelo Ranaldo, Thomas Jordan, Paul Söderlind, The implementation of SNB monetary policy, Financial markets and portfolio management, Vol. 23 (4), 2009. (Journal Article)
We use a regime-switching approach to model the implementation of SNB monetary policy. The regime-switching technique is crucial for assessing the flexibility inherent in the SNB’s monetary policy strategy. The empirical findings support the idea that repo operations are instrumental in smoothing the implementation of monetary policy in normal times, while changes in the official operational target, accompanied by the accommodating use of repo operations, produce the intended effects in periods of distress. Another significant contribution also comes from some new measures designed to improve liquidity in the Swiss franc money market during the financial crisis of 2007–2008. |

Cloud computing has gaining importance in the recent past due to the conjunction of well-known key features, such as virtualization and pay-by-use, which together form an innovative concept. Even if cloud computing does not have a widely accepted definition, it has been used for many companies to deploy its infrastructures and promote their business. However, the lack of standards seems to be a drawback related to interoperability and optimization issues.
Convenient actions like changing cloud providers, and/or exchange data/information between clouds may be an arduous work for its customers. Therefore, this paper presents major considerations regarding the lack of cloud standards and pointing why this is considered to be a problem. Furthermore, scenarios are discussed, which are desired to make use of cloud interoperabilityand which are currently initiatives addressing cloud standards issues. This leads to a set of important observations towards a solution solving the interoperability and standardization problem. |
