Recommendations on screen time, sleep and physical activity : associations with academic achievement in Swiss adolescents

Marciano, Laura ; Camerini, Anne-Linda

In: Public health, 2021, vol. 198, p. 211-217

Objectives: This study aimed to investigate how meeting international recommendations for screen time (<2 h/day), moderate-to-vigorous physical activity (MVPA; at least 60 min/day) and sleep (8e10 h/night), as well as media multitasking (MMI) as a form of screen time, impact academic achievement in early adolescence. Study design: A prospective design was used, where self-report measures...

Amstad, Meta ; Müller, Christoph Michael

In: Frontiers in Education, 2020, vol. 4, p. 1-11

Students with intellectual disabilities in special needs schools often exhibit high levels of problem behaviors. Besides of the challenges for the concerned individuals, peers, and their caregivers, problem behaviors can also be a source of stress for teachers. However, less is known on which exact behaviors are perceived as how stressful in special needs schools for students with...

When and how java developers give up static type safety

Mastrangelo, Luis ; Hauswirth, Matthias (Dir.) ; Nystrom, Nathaniel (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019INFO008.

The main goal of a static type system is to prevent certain kinds of errors from happening at run time. A type system is formulated as a set of constraints that gives any expression or term in a program a well-defined type. Besides detecting these kinds of errors, a static type system can be an invaluable maintenance tool, can be useful for documentation purposes, and can aid in generating ...

Metric currents and the Poincaré inequality

Fässler, Katrin ; Orponen, Tuomas

In: Calculus of Variations and Partial Differential Equations, 2019, vol. 58, no. 2, p. 69

We show that a complete doubling metric space (X,d,μ) supports a weak 1-Poincaré inequality if and only if it admits a pencil of curves (PC) joining any pair of points s,t∈X . This notion was introduced by S. Semmes in the 90’s, and has been previously known to be a sufficient condition for the weak 1-Poincaré inequality. Our argument passes through the intermediate notion of a...

The choice of statistical methods for comparisons of dosimetric data in radiotherapy

Chaikh, Abdulhamid ; Giraud, Jean-Yves ; Perrin, Emmanuel ; Bresciani, Jean-Pierre ; Balosso, Jacques

In: Radiation Oncology, 2014, vol. 9, no. 1, p. 205

Purpose: Novel irradiation techniques are continuously introduced in radiotherapy to optimize the accuracy, the security and the clinical outcome of treatments. These changes could raise the question of discontinuity in dosimetric presentation and the subsequent need for practice adjustments in case of significant modifications. This study proposes a comprehensive approach to compare different...
