Propuesta de tiendas escolares saludables con inclusión social y construcción de seguridad alimentaria y nutricional en comunidades educativas del municipio de Madrid Cundinamarca

Con el propósito de establecer una propuesta metodológica que apunte a la transformación de las tiendas escolares en entornos saludables y con conexión con tres Instituciones Educativas Departamentales del municipio de Madrid, proponiendo alternativas de inclusión social y SAN, se desarrolló el presente proyecto recurriendo en una exploración cuantitativa y cualitativa. La investigación caracterizó las tiendas escolares existentes en las instituciones educativas por medio de encuestas, con el fin de reconocer la oferta de alimentos y el cumplimiento de la resolución vigente en el territorio; y de entrevistas semiestructuradas, identificando la opinión y percepción de los consumidores, comercializadores, productores y de otros actores sobre la tienda escolar, con el fin de conocer sus puntos de vista. Se obtuvo un conjunto de información que se utilizó para generar insumos para la formulación de políticas municipales que rijan las Tiendas Escolares Saludables - TES en el municipio de Madrid. Los resultados obtenidos ofrecen aspectos y recomendaciones que apuntan a transformar algunos aspectos de las tiendas escolares tradicionales en TES, es decir, que lleguen a ser entornos saludables, de tal manera que avancen a ser escenarios generadores de equidad que incluyan a los proveedores locales, para así construir procesos de SAN que beneficien a los actores involucrados y beneficiados de las tiendas en las comunidades educativas del municipio de Madrid, Cundinamarca. Se identificó que la participación de los actores, la inclusión de mecanismos de control social, y programas de educación alimentaria y nutricional enfocados en generar equidad, son opciones posibles para llegar a TES incluyentes y sostenibles.Abstract: With the purpose of establishing a methodological proposal that points to the transformation of school stores in healthy environments and with connection to three Departmental Educational Institutions of the municipality of Madrid, proposing alternatives for social inclusion and SAN, the present project was developed using an exploration quantitative and qualitative. The research characterized the existing school stores in educational institutions through surveys, in order to recognize the supply of food and compliance with the actual resolution in the territory; and semi-structured interviews, identifying the opinion and perception of consumers, marketers, producers and other actors about the school store, in order to know their points of view. A set of information was obtained that was used to generate inputs for the formulation of municipal policies governing Healthy School Stores HSS in the municipality of Madrid. The results obtained offer aspects and recommendations that aim to transform some aspects of traditional school stores in HSS they become healthy environments, in such a way that they become equity generating scenarios that include local suppliers, to thus build SAN processes that benefit the actors involved and benefited from the stores in the educational communities of the municipality of Madrid, Cundinamarca. It was identified that the participation of the actors, the inclusion of social control mechanisms, and food and nutrition education programs focused on generating equity, are possible options to reach inclusive and sustainable HSSMaestrí

Azimuthal separation in nearly back-to-back jet topologies in inclusive 2-and 3-jet events in pp collisions at root s=13TeV

A measurement for inclusive 2- and 3-jet events of the azimuthal correlation between the two jets with the largest transverse momenta, Delta phi(12), is presented. The measurement considers events where the two leading jets are nearly collinear ("back-to-back") in the transverse plane and is performed for several ranges of the leading jet transverse momentum. Proton-proton collision data collected with the CMS experiment at a center-of-mass energy of 13 TeV and corresponding to an integrated luminosity of 35.9 fb(-1) are used. Predictions based on calculations using matrix elements at leading-order and next-to-leading-order accuracy in perturbative quantum chromodynamics supplemented with leading-log parton showers and hadronization are generally in agreement with themeasurements. Discrepancies between the measurement and theoretical predictions are as large as 15%, mainly in the region 177 degrees <Delta phi(12) <180 degrees. The 2- and 3-jet measurements are not simultaneously described by any of models.Peer reviewe

Search for WW boson decays to three charged pions

International audienceFor the first time, a search for the rare decay of the W boson to three charged pions has been performed. Proton-proton collision data recorded by the CMS experiment at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 77.3  fb-1, have been analyzed. No significant excess is observed above the background expectation. An upper limit of 1.01×10-6 is set at 95% confidence level on the branching fraction of the W boson to three charged pions. This provides a strong motivation for theoretical calculations of this branching fraction
