We first reflect how blockchains could be used in the context of the established BPM lifecycle and second how they might become relevant beyond.

Today, recognition decisions are still made more or less on a case-by-case basis. However, digital certification approaches are now emerging that could automate recognition processes. The technical development of the required machinereadable documents and infrastructures is already well advanced in some cases. The DigiCerts consortium has developed a solution based on a collective blockchain. There are ongoing and open discussions regarding the particular technology, but the institutional implementation of digital certificates raises further questions. A number of workshops have been held at the Institute for Interactive Systems at Technische Hochschule L{\"u}beck, which have identified the need for new responsibilities for issuing certificates. It has also become clear that all members of higher education institutions need to develop skills in the use of digital certificates.}, language = {en} } @inproceedings{EsveldVriesBecchettietal.2023, author = {Esveld, Selma van and Vries, Nardo de and Becchetti, Sibilla and Dopper, Sofia and Valkenburg, Willem van and Carlon, May Kristine Jonson and Yokoi, Kensuke and Gayed, John Maurice and Suyama, Hiroshi and Cross, Jeffrey Scott and Jin, Tonje and Xue, Wei and Bruillard, {\´E}ric and Steinbeck, Hendrik and Meinel, Christoph and {\"O}zdemir, Paker Doğu and Can Bayer, Burak and Mercan, Duygu and Buyurucu, Gamze and Haugsbakken, Halvdan and Hagelia, Marianne and Ebner, Martin and Edelsbrunner, Sarah and Hohla-Sejkora, Katharina and Lipp, Silvia and Sch{\"o}n, Sandra and Xiaoxiao, Wang and Shuangshuang, Guo and Morales-Chan, Miguel and Amado-Salvatierra, H{\´e}ctor R. and Hern{\´a}ndez-Rizzardini, Rocael and Egloffstein, Marc and H{\"u}nemohr, Holger and Ifenthaler, Dirk and Dixon, Fred and Trabucchi, Stefania and Khaneboubi, Mehdi and Giannatelli, Ada and Tomasini, Alessandra and Staubitz, Thomas and Serth, Sebastian and Thomas, Max and Koschutnig-Ebner, Markus and Rampelt, Florian and Stetten, Alexander von and Wittke, Andreas and Theeraroungchaisri, Anuchai and Thammetar, Thapanee and Duangchinda, Vorasuang and Khlaisang, Jintavee and Mair, Bettina and Steinkellner, Iris and Stojcevic, Ivana and Zwiauer, Charlotte and Thirouard, Maria and Vill{\`e}sbrunne, Marie de la and Bernaert, Oliver and Nohr, Magnus and Alario Hoyos, Carlos and Delgado Kloos, Carlos and Kiendl, Doris and Terzieva, Liliya and Concia, Francesca and Distler, Petr and Law, Gareth and Macerata, Elena and Mariani, Mario and Mossini, Eros and Negrin, Maddalena and Štrok, Marko and Neub{\"o}ck, Kristina and Linschinger, Nadine and Lorenz, Anja and Bock, Stefanie and Schulte-Ostermann, Juleka and Moura Santos, Ana and Corti, Paola and Costa, Luis Felipe Coimbra and Utunen, Heini and Attias, Melissa and Tokar, Anna and Kennedy, Eileen and Laurillard, Diana and Zeitoun, Samar and Wasilewski, Julie and Shlaka, Souhad and Ouahib, Sara and Berrada, Khalid and Dietz, Michael and Roth, Dennis}, title = {EMOOCs 2023}, editor = {Meinel, Christoph and Schweiger, Stefanie and Staubitz, Thomas and Conrad, Robert and Alario Hoyos, Carlos and Ebner, Martin and Sancassani, Susanna and Żur, Agnieszka and Friedl, Christian and Halawa, Sherif and Gamage, Dilrukshi and Cross, Jeffrey and Jonson Carlon, May Kristine and Deville, Yves and Gaebel, Michael and Delgado Kloos, Carlos and von Schmieden, Karen}, doi = {10.25932/publishup-57645}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-576450}, year = {2023}, abstract = {From June 14 to June 16, 2023, Hasso Plattner Institute, Potsdam, hosted the eighth European MOOC Stakeholder Summit (EMOOCs 2023). The pandemic is fortunately over. It has once again shown how important digital education is. How well-prepared a country was could be seen in our schools, universities, and companies. In different countries, the problems manifested themselves differently. The measures and approaches to solving the problems varied accordingly. Digital education, whether micro-credentials, MOOCs, blended learning formats, or other e-learning tools, received a major boost. EMOOCs 2023 focusses on the effects of this emergency situation. How has it affected the development and delivery of MOOCs and other e-learning offerings all over Europe? Which projects can serve as models for successful digital learning and teaching? Which roles can MOOCs and micro-credentials bear in the current business transformation? Is there a backlash to the routine we knew from pre-Corona times? Or have many things become firmly established in the meantime, e.g. remote work, hybrid conferences, etc.? Furthermore, EMOOCs 2023 has a closer look at the development and formalization of digital learning. Micro-credentials are just the starting point. Further steps in this direction would be complete online study programs or full online universities. Another main topic is the networking of learning offers and the standardization of formats and metadata. Examples of fruitful cooperations are the MOOChub, the European MOOC Consortium, and the Common Micro-Credential Framework. The learnings, derived from practical experience and research, are explored in EMOOCs 2023 in four tracks and additional workshops, covering various aspects of this field.

Recent work suggests that a genetic variation associated with increased dopamine metabolism in the prefrontal cortex (catechol-O-methyltransferase Val158Met; COMT) amplifies age-related changes in working memory performance. Research on younger adults indicates that the influence of dopamine-related genetic polymorphisms on working memory performance increases when testing the cognitive limits through training. To date, this has not been studied in older adults. Method. Here we investigate the effect of COMT genotype on plasticity in working memory in a sample of 14 younger (aged 24-30 years) and 25 older (aged 60-75 years) healthy adults. Participants underwent adaptive training in the n-back working memory task over 12 sessions under increasing difficulty conditions. Results. Both younger and older adults exhibited sizeable behavioral plasticity through training (P < .001), which was larger in younger as compared to older adults (P < .001). Age-related differences were qualified by an interaction with COMT genotype (P < .001), and this interaction was due to decreased behavioral plasticity in older adults carrying the Val/Val genotype, while there was no effect of genotype in younger adults. Discussion. Our findings indicate that age-related changes in plasticity in working memory are critically affected by genetic variation in prefrontal dopamine metabolism.}, language = {en} }
