The appointment of female directors and a gender-diverse boardroom are on average positively associated with...
The predictability of a sequence is defined as the asymptotic performance of the best performing predictor in a given class. The value of the predictability of a sequence will in general depend on the choice of this predictor class. The existence of universal properties of predictability is demonstrated by looking at relationships between different sequences these relationships hold for any cla...
We present results from an analysis of students’ shallow behaviors, i.e., gaming, during their interaction with an Intelligent Tutoring System (ITS). The analysis is based on six college classes using the Andes ITS for homework and test preparation. Our findings show that student features are a better predictor of gaming than problem features, and that individual differences between students im...

The proportion of built-up surface and population density were extracted from buffer zones with radii ranging from 100 to 2000 m, and used...
