The reactor antineutrino anomaly and low energy threshold neutrino experiments

Short distance reactor antineutrino experiments measure an antineutrino spectrum a few percent lower than expected from theoretical predictions. In this work we study the potential of low energy threshold reactor experiments in the context of a light sterile neutrino signal. We discuss the perspectives of the recently detected coherent elastic neutrino-nucleus scattering in future reactor antineutrino experiments. We find that the expectations to improve the current constraints on the mixing with sterile neutrinos are promising. We also analyse the measurements of antineutrino scattering off electrons from short distance reactor experiments. In this case, the statistics is not competitive with inverse beta decay experiments, although future experiments might play a role when compare it with the Gallium anomaly.Comment: 9 pages, 6 figures, 1 table, matches published versio

Action research as a meta-methodology in the management field

Although it was first developed in the field of psychology, action research is a methodology of growing importance in business and management contexts. In this research article, we focus on a significant aspect of action research: the variety of methodologies that can be used jointly in an action research study and its relationships. More specifically, the aim of this study is to underscore the definition of action research as a meta-methodology that encompasses different ways of carrying out empirical research. To this end, we perform a meta-analysis of articles discussing empirical research that used an action research methodology. The meta-analysis is based on a systematic review of articles published between 2000 and 2018. The main findings suggest that action research may be regarded as a multidisciplinary method and that it can be implemented jointly with other methodologies; not just qualitative methods but also quantitative research. Consequently, action research may now be defined as a meta-methodology or an umbrella process. In this way, action research is a tool whose implementation ought to be promoted in the business/management field as a way of enhancing relevant, rigorous empirical studies and serving as a framework reference in projects based on research and practice contribution as well as active collaboration between researchers and practitioners

Research Note:<br>An approach to integrated assessement of reservoir siltation: the Joaquín Costa reservoir as a case study

International audienceIn 1932, the Esera river was dammed at the foothills of the Pyrenean External Ranges; since then, sedimentation has reduced its water storage capacity by a third. This study of the sediments in the Joaquín Costa reservoir has been based on detailed sedimentological examination and other analysis of mineralogy, grain size distribution and the chemical components of the materials accumulated at the bottom of the reservoir. Interpretations are based on results from four sediment cores collected at sites representative of the main environments in the reservoir. Records of known flood events and of reservoir management data have been combined with a 137Cs-derived chronology. Thus, it has been possible to ascribe the sedimentary record at the different reservoir environments to specific years, as well as some main changes in the facies types and sediment components. This methodology is a first approach to assessing siltation processes and dynamics in Mediterranean mountain reservoirs. Keywords: reservoir siltation, mineralogy, sedimentology,sedimentation rates, 137Cs, sediment tracing, mountain reservoir, central Spanish Pyrenee

Procesos de determinación social de la cultura alimentaria en población escolar de Cali, Colombia

Con el objetivo de analizar los procesos de determinación social de la cultura alimentaria en escolares de dos instituciones educativas de la ciudad de Santiago de Cali, se realizó un estudio cualitativo, aplicando el método hermenéutico, con un enfoque de determinación social de la salud y empleando técnicas y herramientas de análisis propias de este método. La información recolectada se obtuvo a partir de talleres con estudiantes de primaria, grupos de discusión con padres de familia, docentes y responsables de la tienda escolar, entrevistas a expertos en política y cultura alimentaria y revisión documental de la política alimentaria vigente. La construcción de la cultura alimentaria de los escolares es un proceso dinámico y complejo que inicia en la familia y la escuela, evidenciando tensiones entre el discurso hegemónico de alimentación saludable y el consumo mediado por el gusto, las nociones, el afecto y los modos de vida. Mientras la política se basa en el concepto de seguridad alimentaria y el enfoque social del riesgo, impidiendo que se garantice el derecho universal a la alimentación en un país en el que abundan las inequidades. Aunque padres y docentes se esfuerzan a diario por proteger a los escolares de las estrategias de la industria alimentaria con recursos que les permitan hacer mejores elecciones, la política alimentaria favorece la perpetuación de las relaciones de dominación. Para lograr mejores resultados en salud es indispensable empoderar a la comunidad y al personal de salud, para generar desde la sociedad acciones que promuevan una alimentación adecuada desde las primeras etapas del desarrollo
