Christoph Eisenegger, Johannes Haushofer, Ernst Fehr, The role of testosterone in social interaction, Trends in Cognitive Sciences, Vol. 15 (6), 2011. (Journal Article)
Although animal researchers established the role of testosterone as a social hormone decades ago, the investigation of its causal influence on human social behaviors has only recently begun. Here, we review and discuss recent studies showing the causal effects of testosterone on social interactions in animals and humans, and outline the basic neurobiological mechanisms that might underlie these effects. Based on these recent findings, we argue that the role of testosterone in human social behavior might be best understood in terms of the search for, and maintenance of, social status. |

(Conference or Workshop Paper published in Proceedings)
In this paper we report on a study exploring multiple aspects of a virtual doctor’s visit as a commonly used example for telemedical services. We compare the conventional doctor’s visit with the virtual visit to identify user requirements and needs for the acceptance of such a scenario. In our survey we retrieved data from a total of 93 users between 16 and 67 years. The results of this study describe differences (and similarities) of criteria for choosing a doctor, basic requirements to accept a virtual doctor’s visit, and people’s opinions on common pro and contra arguments on this scenario. We analyzed the data for potential influences from various user characteristics, such as age, gender, social behavior, or technical competence. Interestingly, most of the reported concerns are not influenced by gender or age, while
participants’ technical self-confidence is related with various acceptance aspects. |

(Conference or Workshop Paper published in Proceedings)
Systematic decision support for architectural design decisions is a major concern for software architects of evolving service-oriented systems. In practice, architects often analyse the expected performance and reliability of design alternatives based on prototypes or former experience. Model-driven prediction methods claim to uncover the tradeoffs between different alternatives quantitatively while being more cost-effective and less error-prone. However, they often suffer from weak tool support and focus on single quality attributes. Furthermore, there is limited evidence on their effectiveness based on documented industrial case studies. Thus, we have applied a novel, model-driven prediction method called Q-ImPrESS on a large-scale process control system consisting of several million lines of code from the automation domain to evaluate its evolution scenarios. This paper reports our experiences with the method and lessons learned. Benefits of Q-ImPrESS are the good architectural decision support and comprehensive tool framework, while one drawback is the time-consuming data collection. |

Emanuel Giger, Martin Pinzger, Harald C Gall, Comparing fine-grained source code changes and code churn for bug prediction, In: 8th working conference on Mining software repositories, Association for Computing Machinery, New York, NY, USA, 2011-05-21. (Conference or Workshop Paper published in Proceedings)
A significant amount of research effort has been dedicated to learning prediction models that allow project managers to efficiently allocate resources to those parts of a software system that most likely are bug-prone and therefore critical. Prominent measures for building bug prediction models are product measures, e.g., complexity or process measures, such as code churn. Code churn in terms of lines modified (LM) and past changes turned out to be significant indicators of bugs. However, these measures are rather imprecise and do not reflect all the detailed changes of particular source code entities during maintenance activities. In this paper, we explore the advantage of using fine-grained source code changes (SCC) for bug prediction. SCC captures the exact code changes and their semantics down to statement level. We present a series of experiments using different machine learning algorithms with a dataset from the Eclipse platform to empirically evaluate the performance of SCC and LM. The results show that SCC outperforms LM for learning bug prediction models. |

When performed on a model, a set of operations (e.g., queries or model transformations) rarely uses all the information present in the model. Unintended underuse of a model can indicate various problems: the model may contain more detail than necessary or the operations may be immature or erroneous. Analyzing the footprints of the operations - i.e., the part of a model actually used by an operation - is a simple technique to diagnose and analyze such problems. However, precisely calculating the footprint of an operation is expensive, because it requires analyzing the operation's execution trace.In this paper, we present an automated technique to estimate the footprint of an operation without executing it. We evaluate our approach by applying it to 75 models and five operations. Our technique provides software engineers with an efficient, yet precise, evaluation of the usage of their models. |

Karl Schmedders, Life-cycle portfolio choice, the wealth distribution and asset prices, In: Joint Research Seminar . 2011. (Conference Presentation)
In this paper we consider a canonical stochastic overlapping generations economy with sequentially complete markets. We examine how aggregate and individual shocks translate to changes in the distribution of wealth and how these movements in the wealth distribution affect asset prices and the interest rate. We show that effects are generally small if agents have identical beliefs but that differences in opinion lead to large movements in the wealth distribution. The interplay of belief heterogeneity and life-cycle savings motives creates very large movements of asset prices and can potentially generate realistic moments of asset returns. |
