This phenomenon has been repeatedly described in recent years but is not yet fully under­stood. Since motivation may relate to different objects such as mathematics or teaching, we aim to qualitatively reconstruct different facets of the central motivational constructs of Situated-Expectancy-Value theory (intrinsic value, attainment value, utility value, cost, and expectancy of success) for preservice mathematics teachers. The analysis of longitudinal group interviews of 14 pre­service higher-secondary mathematic teachers from a German university revealed different objects of motivation (e.g., teaching mathematics, scientific mathematics, procedural mathematics, or proof-based mathematics) in preservice teachers' values and expectancy of success. Furthermore, relations between those values and expectancy of success were identified that played a significant role in preservice teachers’ motivational development over their first semester (e.g., relations of attain­ment value for scientific mathematics and psychological cost). Theoretical and practical implications towards a teaching-specific conceptualization of expectancy of success and values and value interventions are being discussed.}}, title = {{{Preservice teachers’ mathematics-related values and expectancy in the transition from school to university}}}, doi = {{10.48489/QUADRANTE.31191}}, year = {{2023}}, } @article{52861, author = {{Gil, Oliver Fernández and Patrizi, Fabio and Perelli, Giuseppe and Turhan, Anni-Yasmin}}, journal = {{CoRR}}, title = {{{Optimal Alignment of Temporal Knowledge Bases}}}, doi = {{10.48550/ARXIV.2307.15439}}, volume = {{abs/2307.15439}}, year = {{2023}}, } @inproceedings{52863, author = {{Ŝkvorc, Urban and Eftimov, Tome and Koro]ec, Peter}}, booktitle = {{2023 IEEE Symposium Series on Computational Intelligence (SSCI)}}, publisher = {{IEEE}}, title = {{{Analyzing the Generalizability of Automated Algorithm Selection: A Case Study for Numerical Optimization}}}, doi = {{10.1109/ssci52147.2023.10371868}}, year = {{2023}}, } @inproceedings{52913, author = {{Turhan, Anni-Yasmin}}, booktitle = {{Proceedings of the 36th International Workshop on Description Logics {(DL} 2023) co-located with the 20th International Conference on Principles of Knowledge Representation and Reasoning and the 21st International Workshop on Non-Monotonic Reasoning {(KR} 2023 and NMR 2023)., Rhodes, Greece, September 2-4, 2023}}, editor = {{Kutz, Oliver and Lutz, Carsten and Ozaki, Ana}}, publisher = {{CEUR-WS.org}}, title = {{{Brushing-up DLs to Cope with Imperfect Data (Abstract of Joint DL+NMR Invited Talk)}}}, volume = {{3515}}, year = {{2023}}, } @article{45971, abstract = {{Abstract An error estimate for a canonical discretization of the harmonic map heat flow into spheres is derived.

Numer. Anal.}, 59 (2021), pp. 2449-2472] to derive optimal stability and error estimates for both the velocity and the pressure.
