Bullying Behavior and School Bonding for Predicting Student Engagement Among Chilean Adolescents
(2022)
Whereas most research has focused on the influence of teachers on student engagement, we postulate that peer experiences – particularly bullying behavior as a victim or perpetrator – impact student engagement over time. ...

Prevalence of cardiovascular risk factors among Latin American adolescents: a multilevel analysis
(2013-08-15)
High blood pressure (HBP) and obesity is a well-established major risk factor for stroke and coronary heart disease. However, the literatures are scarce about these informations in adolescents from low-and-middle income ...

Multi-level bayesian analysis of piezoelectric energy harvesters
(Universidad de Chile, 2022)
This work proposes a hierarchical Bayesian framework to identify electromechanical properties of Piezoelectric Energy Harvesters (PEHs) and associated uncertainties based on experimental frequency response functions (FRFs). ...
The levels of selection debate: taking into account existing empirical evidence
(Universidad Nacional de Colombia - Sede Bogotá - Faculdad de Ciencias - Departamento de Biología, 2016-09-01)
For over five decades the dominant neo-Darwinian view is that natural selection acts only at the genic and organismal levels, but the ignored empirical evidence of multilevel selection occurring in nature obtained over the ...
Drosophila wing modularity revisited through a quantitative genetic approach
(Society for the Study of Evolution, 2016-07)
To predict the response of complex morphological structures to selection it is necessary to know how the covariation among its different parts is organized. Two key features of covariation are modularity and integration. ...
