At the same time, we aim at organizing markets whose participants maintain a lively market of services through appropriate entrepreneurial actions.“ Over the last 12 years, we have developed methods and techniques to address problems critical to the convenient, efficient, and secure use of on-the-fly computing. Among other things, we have made the description of services more convenient by allowing natural language input, increased the quality of configured services through (natural language) interaction and more efficient configuration processes and analysis procedures, made the quality of (the products of) providers in the marketplace transparent through reputation systems, and increased the resource efficiency of execution through reconfigurable heterogeneous computing nodes and an integrated treatment of service description and configuration. We have also developed network infrastructures that have a high degree of adaptivity, scalability, efficiency, and reliability, and provide cryptographic guarantees of anonymity and security for market participants and their products and services. To demonstrate the pervasiveness of the OTF computing approach, we have implemented a proof-of-concept for OTF computing that can run typical scenarios of an OTF market. We illustrated the approach using a cutting-edge application scenario – automated machine learning (AutoML). Finally, we have been pushing our work for the perpetuation of On-The-Fly Computing beyond the SFB and sharing the expertise gained in the SFB in events with industry partners as well as transfer projects. This work required a broad spectrum of expertise. Computer scientists and economists with research interests such as computer networks and distributed algorithms, security and cryptography, software engineering and verification, configuration and machine learning, computer engineering and HPC, microeconomics and game theory, business informatics and management have successfully collaborated here.}}, author = {{Haake, Claus-Jochen and Meyer auf der Heide, Friedhelm and Platzner, Marco and Wachsmuth, Henning and Wehrheim, Heike}}, pages = {{247}}, publisher = {{Heinz Nixdorf Institut, Universität Paderborn}}, title = {{{On-The-Fly Computing -- Individualized IT-services in dynamic markets}}}, doi = {{10.17619/UNIPB/1-1797}}, volume = {{412}}, year = {{2023}}, } @inproceedings{35426, author = {{Richter, Cedric and Haltermann, Jan Frederik and Jakobs, Marie-Christine and Pauck, Felix and Schott, Stefan and Wehrheim, Heike}}, booktitle = {{37th IEEE/ACM International Conference on Automated Software Engineering}}, publisher = {{ACM}}, title = {{{Are Neural Bug Detectors Comparable to Software Developers on Variable Misuse Bugs?}}}, doi = {{10.1145/3551349.3561156}}, year = {{2023}}, } @inproceedings{36848, author = {{Schott, Stefan and Pauck, Felix}}, booktitle = {{2022 IEEE 22nd International Working Conference on Source Code Analysis and Manipulation (SCAM)}}, publisher = {{IEEE}}, title = {{{Benchmark Fuzzing for Android Taint Analyses}}}, doi = {{10.1109/scam55253.2022.00007}}, year = {{2023}}, } @inproceedings{35427, author = {{Pauck, Felix}}, booktitle = {{37th IEEE/ACM International Conference on Automated Software Engineering}}, publisher = {{ACM}}, title = {{{Scaling Arbitrary Android App Analyses}}}, doi = {{10.1145/3551349.3561339}}, year = {{2023}}, } @inproceedings{33488, author = {{Ksouri-Gerwien, C. and Vorbohle, Christian}}, booktitle = {{Proceedings of the 55th Hawaii International Conference on System Sciences (HICSS)}}, location = {{Maui, Hawaii, USA}}, title = {{{Supporting Business Model Decision-making in B2B Ecosystems: A Framework for Using System Dynamics}}}, year = {{2023}}, } @misc{40440, author = {{Pilot, Matthias}}, title = {{{Updatable Privacy-Preserving Reputation System based on Blockchain}}}, year = {{2023}}, } @misc{43058, author = {{Tiessen, Michelle}}, title = {{{Zur Effektivität des europäischen Kronzeugenprogramms - Der Fall des LKW-Kartells}}}, year = {{2023}}, } @article{43109, author = {{Götte, Thorsten and Kolb, Christina and Scheideler, Christian and Werthmann, Julian}}, journal = {{Theor.

In our theoretical model, physicians are faced with a heterogeneous patient population, in which patients systematically vary with regard to both their responsiveness to the provided quality of care and their state of health. We test the behavioral predictions derived from this model in a controlled laboratory experiment. In line with the model, we observe that competition significantly improves patient benefits as long as patients are able to respond to the quality provided. For those patients, who are not able to choose a physician, competition even decreases the patient benefit compared to a situation without competition. This decrease is in contrast to our theoretical prediction implying no change in benefits for passive patients. Deviations from patient-optimal treatment are highest for passive patients in need of a low quantity of medical services. With repetition, both, the positive effects of competition for active patients as well as the negative effects of competition for passive patients become more pronounced. Our results imply that competition can not only improve but also worsen patient outcome and that patients’ responsiveness to quality is decisive.}}, author = {{Brosig-Koch, Jeannette and Hehenkamp, Burkhard and Kokot, Johanna}}, journal = {{Health Economics}}, keywords = {{physician competition, patient characteristics, heterogeneity in quality responses, fee-for-service, laboratory experiment}}, title = {{{Who benefits from quality competition in health care?

The model is relevant in markets such as public health care, education and schooling, or postal services. We find that, when the regulated price is low or intermediate, the entrant strategically locates towards the corner of the market to keep the incumbent at the low monopoly quality level. For a high price, the entrant locates at the corner of the market and both providers implement higher quality compared to a monopoly. In any case, the entrant implements higher quality than the incumbent provider. Social welfare is always higher in a duopoly if the cost of quality is low. For higher cost levels welfare is non-monotonic in the price and it can be optimal to the regulator not to use its entire budget. Therefore, the welfare effect of entry depends on the price and the size of the entry cost, and the regulator should condition the decision to allow entry on an assessment of the entry cost.}}, author = {{Hehenkamp, Burkhard and Kaarbøe, Oddvar M.}}, keywords = {{Quality competition, Price regulation, Location choice, Product differentiation}}, title = {{{Price Regulation, Quality Competition and Location Choice with Costly Relocation}}}, year = {{2023}}, } @article{44077, author = {{Maack, Marten}}, issn = {{0167-6377}}, journal = {{Operations Research Letters}}, keywords = {{Applied Mathematics, Industrial and Manufacturing Engineering, Management Science and Operations Research, Software}}, number = {{3}}, pages = {{220--225}}, publisher = {{Elsevier BV}}, title = {{{Online load balancing on uniform machines with limited migration}}}, doi = {{10.1016/j.orl.2023.02.013}}, volume = {{51}}, year = {{2023}}, } @misc{43374, author = {{Schürmann, Patrick}}, title = {{{ A Formal Comparison of Advanced Digital Signature Primitives}}}, year = {{2023}}, } @inproceedings{44194, author = {{Ahmed, Qazi Arbab and Awais, Muhammad and Platzner, Marco}}, booktitle = {{The 24th International Symposium on Quality Electronic Design (ISQED'23), San Francisco, Califorina USA}}, location = {{San Fransico CA 94023-0607, USA}}, title = {{{MAAS: Hiding Trojans in Approximate Circuits}}}, year = {{2023}}, } @misc{44735, author = {{Schweichhart, Jonas}}, title = {{{Minimum Edge Cuts in Overlay Networks}}}, year = {{2023}}, } @article{44897, author = {{Kaimann, Daniel and Spiess Bru, Clarissa Laura Maria and Frick, Bernd}}, journal = {{Journal of Wine Economics}}, title = {{{Ratings Meet Prices: The Dynamic Relationship of Quality Signals}}}, year = {{2023}}, } @phdthesis{43108, author = {{Pauck, Felix}}, publisher = {{Paderborn University}}, title = {{{Cooperative Android App Analysis}}}, doi = {{10.17619/UNIPB/1-1698}}, year = {{2023}}, } @inproceedings{45188, author = {{Werthmann, Julian and Scheideler, Christian and Coy, Sam and Czumaj, Artur and Schneider, Philipp}}, title = {{{Routing Schemes for Hybrid Communication Networks}}}, doi = {{10.48550/ARXIV.2210.05333}}, year = {{2023}}, }
