Las prácticas radiales de los chicos en ámbitos socio-culturales diversos : "Sostienen los chicos" del colegio Hans Andersen en la radio FM Palermo 94.7 Mhz C.A.B.A y "Radio 4" 96.1 Mhz de la Escuela de Educación Técnica del Complejo Habitacional Ejército de los Andes del partido de 3 de Febrero del conurbano bonaerense

Los programas radiales implican interacción humana, creativa o dirigida y desde el comienzo del siglo XXI comenzaron a transformarse también en herramientas de educación no formal, que permitieron una evolución personal y de adaptación social en niños y adolescentes. Bajo el nombre de Talleres de Radios Escolares buscan además de entretener, observar: modos de expresión, colaboración, tolerancia, seguridad y autoestima. Los programas radiales hechos por niños, tienen diferencias significativas, según el ámbito socio-cultural proveniente. Al expresarse libremente - cuando esto es posible- se sienten unidos y generan resistencia o contracultura al lenguaje y visión de los adultos. En las teorías de comunicación que estudiaron los efectos en las audiencias –como la de la aguja hipodérmica- se puso atención en los efectos negativos de los medios, sin embargo es posible que sean una herramienta para mejorar la calidad de vida de las personas. En los Talleres de Radio Sostienen los chicos y Radio Cuatro han sido diferentes las incidencias en la emisión y propagación de las audiciones, de acuerdo al ámbito socio-cultural diverso al que pertenecen. En el marco de las políticas públicas, en lo que a educación no formal se refiere, los centros de actividades juveniles fomentan el desarrollo intelectual dentro de la política educativa, hacia nuevas estrategias pedagógicas y comunicacionales.Facultad de Periodismo y Comunicación Socia

Search for heavy resonances decaying to ZZ or ZW and axion-like particles mediating nonresonant ZZ or ZH production at s \sqrt{s} = 13 TeV

International audienceA search has been performed for heavy resonances decaying to ZZ or ZW and for axion-like particles (ALPs) mediating nonresonant ZZ or ZH production, in final states with two charged leptons (ℓ = e, μ) produced by the decay of a Z boson, and two quarks produced by the decay of a Z, W, or Higgs boson H. The analysis is sensitive to resonances with masses in the range 450 to 2000 GeV. Two categories are defined corresponding to the merged or resolved reconstruction of the hadronically decaying boson. The search is based on data collected during 2016–2018 by the CMS experiment at the LHC in proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 138 fb$^{−1}$. No significant excess is observed in the data above the standard model background expectation. Upper limits on the production cross section of heavy, narrow spin-2 and spin-1 resonances are derived as functions of the resonance mass, and exclusion limits on the production of bulk graviton particles and W′ bosons are calculated in the framework of the warped extra dimensions and heavy vector triplet models, respectively. In addition, upper limits on the ALP-mediated diboson production cross section and ALP couplings to standard model particles are obtained in the framework of linear and chiral effective field theories. These are the first limits on nonresonant ALP-mediated ZZ and ZH production obtained by the LHC experiments.[graphic not available: see fulltext
