Quality of life of portuguese and spanish adolescents. A comparative study between natives and immigrants

The aim of this study was to analyse differences in quality of life (QOL) between Spanish and Portuguese immigrant and native adolescents. In total, 475 native and immigrant adolescents (52% boys) from Algarve (Portugal) and Huelva (Spain), aged between 12 and 17 years old, were assessed with the KIDSCREEN-52. QOL dimensions were not related to most academic variables, with the exception of number of school failures, Financial Resources and Social Support from Peers. Multivariate analysis of variance (MANOVA) was used to examine statistical differences in adolescents QOL. Age differences in QOL levels were not found. Girls reported worse QOL levels on Physical Wellbeing than boys (F = 10.32, p = .001, eta(2) = .02). Immigrant Portuguese adolescents scored higher on Mood (F = 17.57, p = .000, eta(2) = .11), and native Portuguese adolescents scored higher on Social Acceptance (F = 4.87, p = .002, eta(2) = .033). Immigrant and native adolescents had similar levels of perceived QOL. Overall, it seems that in both countries, the living contexts for immigrant and native adolescents are fairly homogeneous

Power-law relaxation in human violent conflicts

We study relaxation patterns of violent conflicts after bursts of activity. Data were obtained from available catalogs on the conflicts in Iraq, Afghanistan and Northern Ireland. We find several examples in each catalog for which the observed relaxation curves can be well described by an asymptotic power-law decay (the analog of the Omori’s law in geophysics). The power-law exponents are robust, nearly independent of the conflict. We also discuss the exogenous or endogenous nature of the shocks. Our results suggest that violent conflicts share with earthquakes and other natural and social phenomena a common feature in the dynamics of aftershocks
