In this study, 1,067 participants from three groups (students (ST), administrative and service staff (AS) and teaching and research staff (TR)) from all the educational centers completed the Morningness-Eveningness Questionnaire (MEQ) adapted to Spanish. The majority of the circadian typology in the three groups was intermediate, with a percentage higher than 60% in each of them. With this in mind, certain socio-demographic factors were also evaluated, such as age and gender. Younger participants tended to have an evening circadian typology. In terms of gender, both male and female participants who were not in the middle of the day were more representative of the morning typology. To complement the study, 9 participants were interviewed to explore the health effects of chronotype synchronisation/(de)synchronisation in the different university groups, with a stronger influence observed in students and teaching and research staff.

We prove a variant of Gantmacher’s weak compactness theorem for multilinear operators. We also present Lions–Peetre type results on weak compactness interpolation for multilinear operators. Furthermore, we provide an analogue of Persson’s result on interpolation of weakly compact operators under the assumption that the target Banach couple satisfies a certain weakly compact approximation property.

We introduce and discuss several ways of extending the inner measure arisen from the closed injective hull of an ideal of linear operators to the multilinear case. In particular, we consider new measures that allow to characterize the operators that belong to a closed injective ideal of multilinear operators as those having measure equal to zero. Some interpolation formulas for these measures, and consequently interpolation results involving ideals of multilinear operators, are established. Examples and applications related to summing multilinear operators are also shown.

In this paper we introduce a function for multilinear operators that can be considered as an extension of the so-called outer measure associated to a linear operator ideal. We prove that it allows to characterize the operators that belong to a closed surjective ideal of multilinear operators as those having measure equal to zero. We also obtain some interpolation formulas for this new measure. As a consequence we deduce interpolation results for arbitrary closed surjective ideals of multilinear operators which recover, in particular, different results previously established in the literature.
