High-quality chest compressions are pivotal to improve survival from cardiac arrest. Basic life support training of school students is an international priority. The aim of this trial was to assess the effectiveness of a real-time training software (Laerdal QCPR®) compared to a standard instructor-based feedback for chest compressions acquisition in secondary school students. After an interacti...

The present study explored the effects of lecture fluency on students’ metacognitive awareness and regulation. Participants watched one of two short videos of an instructor explaining a scientific concept. In the fluent video, the instructor stood upright, maintained eye contact, and spoke fluidly without notes. In the disfluent video, the instructor slumped, looked away, and spoke haltingly wi...

In this lecture we will be looking into the secretary problem, and an interesting variation of the problem called the incentive comparable secretary problem. For both of these problems we will show how they can be solved though a correspondence between all possible strategies and the feasible solution space to a linear program. In both cases this will allow us to derive an algorithm and prove t...

In this paper we describe a method for developing a virtual instructor for pedestrian navigation based on real interactions between a human instructor and a human pedestrian. A virtual instructor is an agent capable of fulfilling the role of a human instructor, and its goal is to assist a pedestrian in the accomplishment of different tasks within the context of a real city. The instructor decid...
