- Teacher shortages are a phenomenon of growing international concern. The causes of this phenomenon are the focus of the research project What About Teacher Shortage (WATS up), which uses an international comparative perspective to analyse teacher shortages in Denmark, Germany, and Sweden. Because the nature of teacher shortages’ development is complex and influenced by several interacting factors, this theoretical article accounts for the complexity of the phenomenon and introduces a theoretical and methodological model for empirical research. The theoretical starting point is a policy problem approach; more precisely, one that adapts Bacchi’s model on focusing ‘what the problem is represented to be’ (WPR). Due to variations between the studied countries, a multiple case design is chosen as the methodological approach. This allows an individual analysis as well as a comparison of the countries. A methodological model comprising 8 parameters and 23 indicators summarizes the interacting factors influencing teacher shortages.

Optimal Day-Ahead Orders Using Stochastic Programming and Noise-Driven Recurrent Neural Networks

Conference paper (peer-reviewed)abstract
- This paper presents a methodology for strategic day-ahead planning that uses a combination of deep learning and optimization. A noise-driven recurrent neural network structure is proposed for forecasting electricity prices and local inflow to water reservoirs. The resulting forecasters generate predictions with seasonal variation without relying on long input sequences. This forecasting method is employed in a stochastic program formulation of the day-ahead problem. This results in optimal order strategies for a price-taking hydropower producer participating in the Nordic day-ahead market. Using an open-source software framework for stochastic programming, the model is implemented and distributed over multiple cores. The model is then solved in parallel using a sampling-based algorithm. Tight confidence intervals around the stochastic solution are provided, which show that the gain from adopting a stochastic approach is statistically significant.

Grain boundary interaction based on gradient crystal inelasticity and decohesion
- 2020
-
In: Computational Materials Science. - : Elsevier BV. - 0927-0256. ; 178
-
Journal article (peer-reviewed)abstract
- This paper presents a model for geometrically non-coherent grain boundary interaction premised on gradient-extended crystal inelasticity. The appropriate kinematics, the constitutive relations and the balance equations are established for a polycrystal including grain interaction. More specifically, this contribution proposes a coupling of the microtraction and grain boundary decoheion, which is represented as damage. As a consequence, decohesion exerts an impact on the standard tractions as well as on the microtractions along the grain boundaries. The appropriate modeling framework is assessed in terms of numerical results for a bicrystal that is subjected to simple shear. A comparison with the situation without such coupling effect shows that the microtractions along the grain boundary reduce for increasing damage and a microfree boundary is approached when the damage approaches unity.
