As a baseline result, we provide evidence for significantly positive cumulative average abnormal CDS spread changes for both, European and North American acquirers suggesting that CDS investors perceive an increase in the acquiring firms’ credit risk exposures due to M&A announcements. Our baseline finding holds under several robustness checks, especially when controlling for the robustness of the empirical design. Moreover, results from a large variety of sensitivity analyses reveal a number of deal and firm characteristics that may explain why CDS investors from our sample expect an increase in the acquirers’ credit risk exposures due to forthcoming M&A transactions. }}, author = {{Hippert, Benjamin and Uhde, André}}, keywords = {{credit default swaps, risk perception of CDS investors, mergers and acquisitions, event study}}, title = {{{CDS Investors’ Risk Perceptions of M&A Announcements}}}, year = {{2021}}, } @techreport{36063, abstract = {{This paper empirically investigates determinants of the outstanding net notional amount of credit default swaps (CDSs) contracts written on banks.

Furthermore, being classified as a G-SIB, being a constituent of the main CDS index and the equity trading volume may significantly explain changes in the outstanding CDS net notional on banks.

Ihm geht es um die Frage, an welchen Orten und auf welche Weise Malerei im Jahr 2021 entsteht: Wie sieht es mit den althergebrachten Kategorisierungen von Farbe und Form, Figuration und Abstraktion oder Fläche und Raum aus? Welche Wege sucht sich vor diesem Hintergrund die heutige Malerei und welche ästhetische Kraft ist ihr eigen? Die 32 Bilder der Serie Der Wunsch zu verschwinden (Camopedia) basieren auf den 32 Farbtönen des Systems «Alpina Feine», die Schulze verwendet, um unterschiedliche Camouflage-Muster zu malen. Dieses speziell kuratierte Farbsystem wird aus Marketinggründen mit Wohlfühlassoziationen verbunden. Diese Aufladung crasht mit der Verwendung des Tarnmusters im militärischen Bereich. Schulze beschäftigt die Frage, warum gerade heute, in einer Zeit, die von vielen politischen und sozialen Veränderungen bestimmt ist, Camouflage in Mode und Design allgegenwärtig ist. Für die Serie Cool Mild Pure Warm (Streetfile) greift Schulze ebenfalls auf Farbsysteme zurück, die er mit Fotos von diversen Farb-Attentaten im öffentlichen Raum kombiniert. So entsteht ein – nicht ganz humorloser – Kommentar zur kommerziellen Nutzung von Farbe in Farbsystemen, aber auch zu deren Zweckentfremdung durch politische «Attacken» im öffentlichen Raum. Der Name der Serie EPS bezieht sich auf ein Material, das unter dem Markennamen Styropor bekannt ist.

Our presented solution is an advancement of our system used in the previous edition of the task.We use a forward-backward convolutional recurrent neural network (FBCRNN) for tagging and pseudo labeling followed by tag-conditioned sound event detection (SED) models which are trained using strong pseudo labels provided by the FBCRNN. Our advancement over our earlier model is threefold. First, we introduce a strong label loss in the objective of the FBCRNN to take advantage of the strongly labeled synthetic data during training. Second, we perform multiple iterations of self-training for both the FBCRNN and tag-conditioned SED models. Third, while we used only tag-conditioned CNNs as our SED model in the previous edition we here explore sophisticated tag-conditioned SED model architectures, namely, bidirectional CRNNs and bidirectional convolutional transformer neural networks (CTNNs), and combine them. With metric and class specific tuning of median filter lengths for post-processing, our final SED model, consisting of 6 submodels (2 of each architecture), achieves on the public evaluation set poly-phonic sound event detection scores (PSDS) of 0.455 for scenario 1 and 0.684 for scenario as well as a collar-based F1-score of 0.596 outperforming the baselines and our model from the previous edition by far.

Despite the availability of large-scale data sets such as Google's AudioSet, acquiring training data matching a certain application environment is still often a problem. In this paper we are concerned with human activity monitoring in a domestic environment using an ASN consisting of multiple nodes each providing multichannel signals. We propose a self-training based domain adaptation approach, which only requires unlabeled data from the target environment. Here, a sound recognition system trained on AudioSet, the teacher, generates pseudo labels for data from the target environment on which a student network is trained. The student can furthermore glean information about the spatial arrangement of sensors and sound sources to further improve classification performance. It is shown that the student significantly improves recognition performance over the pre-trained teacher without relying on labeled data from the environment the system is deployed in.}}, author = {{Ebbers, Janek and Keyser, Moritz Curt and Haeb-Umbach, Reinhold}}, booktitle = {{Proceedings of the 29th European Signal Processing Conference (EUSIPCO)}}, pages = {{1135–1139}}, title = {{{Adapting Sound Recognition to A New Environment Via Self-Training}}}, year = {{2021}}, } @article{29901, author = {{Santos, Beatriz Sousa and Domik, Gitta and Anderson, Eike Falk}}, journal = {{Graph.

In this paper, we argue that a novel conceptual framework is needed to overcome shortcomings of existing AI systems with little attention to processes of interaction and learning. Drawing from research in interaction and development, we first outline the novel conceptual framework that pushes the design of AI systems toward true interactivity with an emphasis on the role of the partner and social relevance. We propose that AI systems will be able to provide a meaningful and relevant explanation only if the process of explaining is extended to active contribution of both partners that brings about dynamics that is modulated by different levels of analysis. Accordingly, our conceptual framework comprises monitoring and scaffolding as key concepts and claims that the process of explaining is not only modulated by the interaction between explainee and explainer but is embedded into a larger social context in which conventionalized and routinized behaviors are established. We discuss our conceptual framework in relation to the established objectives of transparency and autonomy that are raised for the design of explainable AI systems currently.}}, author = {{Rohlfing, Katharina J. and Cimiano, Philipp and Scharlau, Ingrid and Matzner, Tobias and Buhl, Heike M. and Buschmeier, Hendrik and Esposito, Elena and Grimminger, Angela and Hammer, Barbara and Haeb-Umbach, Reinhold and Horwath, Ilona and Hüllermeier, Eyke and Kern, Friederike and Kopp, Stefan and Thommes, Kirsten and Ngonga Ngomo, Axel-Cyrille and Schulte, Carsten and Wachsmuth, Henning and Wagner, Petra and Wrede, Britta}}, issn = {{2379-8920}}, journal = {{IEEE Transactions on Cognitive and Developmental Systems}}, keywords = {{Explainability, process ofexplaining andunderstanding, explainable artificial systems}}, number = {{3}}, pages = {{717--728}}, title = {{{Explanation as a Social Practice: Toward a Conceptual Framework for the Social Design of AI Systems}}}, doi = {{10.1109/tcds.2020.3044366}}, volume = {{13}}, year = {{2021}}, } @inbook{49487, author = {{Malancu, Natalia and Florea, Alexandra}}, booktitle = {{Handbook of Citizenship and Migration}}, editor = {{Giugni, Marco and Grasso, Maria}}, title = {{{Chapter 5: Quantitative methodological approaches to citizenship and migration}}}, doi = {{https://doi.org/10.4337/9781789903133.00011}}, year = {{2021}}, } @techreport{47098, author = {{Alt, Marius and Gallier, Carlo and Sturm, Bodo and Kesternich, Martin}}, publisher = {{ZEW Policy Brief 21-09}}, title = {{{Ausblick auf die COP26 in Glasgow, Eine schrittweise Erhöhung der Klimaschutzbeiträge reicht nicht – ein Klimaklub sollte mitgedacht werden}}}, year = {{2021}}, } @techreport{47100, author = {{Frick, Marc and Conzelmann, Annabell and von Graevenitz, Kathrine and Kesternich, Martin and Wagner, Ulrich and Rausch, Sebastian}}, title = {{{Transparente Klimabilanzen - Information für klimafreundliches Handeln}}}, year = {{2021}}, }
