An important challenge facing entrepreneurship researchers is the “three-body” knowledge problem of how to use “theoretical knowledge” to produce “prescriptive knowledge” that communicates the “practical knowledge” of situated practice to students and practitioners of entrepreneurship. We argue that a contribution can be made to solving this problem by theorizing practical knowledge as the “know-how” to do a situated entrepreneurial practice. “Know-how” is a cognitive “capacity to act” that prescribes for a practitioner how to produce a type of outcome in a range of circumstances. This “know-how” can potentially, therefore, be reconstructed theoretically as explicit micro-prescriptive guidelines for third-party practice. To exploit this connection between practical knowledge and prescriptive knowledge, however, we first need to overcome the problem that “know-how” is largely tacit in the moment of real-time forward-looking practice. In other words, the practitioner is not directly aware of their tacit “know-how”, or “tacit knowledge”, at the time of practice. In this article, we explore the contribution design theory can make to empirically eliciting, and conceptually inferring, the real-time “tacit knowledge” of entrepreneurial practice as a precursor to producing micro-prescriptive knowledge.

Combinatorial bi-level optimization remains a challenging topic, especially when the lower-level is a NP-hard problem. In this work, we tackle large-scale and combinatorial bi-level problems using GP Hyper-heuristics, i.e., an approach that permits to train heuristics like a machine learning model. Our contribution aims at targeting the intensive and complex lower-level optimizations that occur when solving a large-scale and combinatorial bi-level problem. For this purpose, we consider hyper-heuristics through heuristic generation. Using a GP hyper-heuristic approach, we train greedy heuristics in order to make them more reliable when encountering unseen lower-level instances that could be generated during bi-level optimization. To validate our approach referred to as GA+AGH, we tackle instances from the Bi-level Cloud Pricing Optimization Problem (BCPOP) that model the trading interactions between a cloud service provider and cloud service customers. Numerical results demonstrate the abilities of the trained heuristics to cope with the inherent nested structure that makes bi-level optimization problems so hard. Furthermore, it has been shown that training heuristics for lower-level optimization permits to outperform human-based heuristics and metaheuristics which constitute an excellent outcome for bi-level optimization.

Ein hoher Gemüse- und Obstverzehr ist Teil eines gesunden Lebensstils. In der HBSC-Studie 2014 wurden die Schüler daher gefragt, wie häufig sie Obst und Gemüse essen: 37 % gaben an, täglich Obst zu essen und 32 % gaben den täglichen Verzehr von Gemüse an. Schüler der Altersgruppe 11-12 essen häufiger Obst und Gemüse als Schüler im Alter von 13-18. Der tägliche Konsum von Obst und Gemüse ist bei Mädchen häufiger als bei Jungen. Des Weiteren ist der tägliche Konsum bei Schülern aus wohlhabenden Familien weiter verbreitet als bei Schülern aus nicht wohlhabenden Familien. Schüler des Fondamental und des Enseignement secondaire geben einen täglichen Verzehr häufiger an als Schüler des Enseignement secondaire technique und des Modulaire. [less ▲]
