GRS computation of deep inelastic electron scattering on 4He

We compute cross sections for inclusive scattering of high energy electrons on 4He, based on the two lowest orders of the Gersch-Rodriguez-Smith (GRS) series. The required one- and two-particle density matrices are obtained from non-relativistic 4He wave functions using realistic models for the nucleon-nucleon and three-nucleon interaction. Predictions for E=3.6 GeV agree well with the NE3 SLAC-Virginia data.Comment: 18 pages, 7 figures, submitted to PR

National identity predicts public health support during a global pandemic

Changing collective behaviour and supporting non-pharmaceutical interventions is an important component in mitigating virus transmission during a pandemic. In a large international collaboration (Study 1, N = 49,968 across 67 countries), we investigated self-reported factors associated with public health behaviours (e.g., spatial distancing and stricter hygiene) and endorsed public policy interventions (e.g., closing bars and restaurants) during the early stage of the COVID-19 pandemic (April-May 2020). Respondents who reported identifying more strongly with their nation consistently reported greater engagement in public health behaviours and support for public health policies. Results were similar for representative and non-representative national samples. Study 2 (N = 42 countries) conceptually replicated the central finding using aggregate indices of national identity (obtained using the World Values Survey) and a measure of actual behaviour change during the pandemic (obtained from Google mobility reports). Higher levels of national identification prior to the pandemic predicted lower mobility during the early stage of the pandemic (r = −0.40). We discuss the potential implications of links between national identity, leadership, and public health for managing COVID-19 and future pandemics.publishedVersio

Percepción de violencia desde escolares de dos instituciones educativas de la localidad de Kennedy, Bogotá

Objective To describe the perception of violence in schoolchildren of two schools of the borough of Kennedy, Bogotá. Methods Participatory action research (PAR) and qualitative study. The participants in these focus groups were chosen randomly, 5 students per course, for a total of 15 focus groups and 75 students included, prior informed consent from parents and students. Ethical aspects were taken into account. Results 61 participants, 30 boys (49.1%) and 31 girls (50.8%), were included in the study, with an age range between 5 and 12 years. 10 participants (16.3%) were kindergarten students, 3 were first-grade students (4.9%), 10 second-grade students (16.3%), 18 third-grade students (29.5%), 10 fourth-grade students (16.3%), and 10 fifth-grade students (16.3%). The socioeconomic status of the children was ranked as 1 and 2. The results are presented in four categories: causes, problems, consequences and solutions, from which 8 subcategories emerged; they describe the perception that children have about violence at home and schools, highlighting physical and verbal domestic violence, the use of psychoactive substances and sexual abuse. Conclusion There is evidence in the school population of the borough of Kennedy that violence is a public health problem established in homes and in schools. The origin of this violence is mainly children's homes, therefore, it is important to build and generate proposals for intervention based on the solutions raised by the children themselves regarding the structural and family levels. © 2018, Universidad Nacional de Colombia.
