    El trabajo de investigación ha tenido por objeto proponer las mejoras a implementar en la Ley N° 31188 que regula la negociación colectiva del sector estatal, utilizando el enfoque cualitativo, método analítico y bibliográfico. Se obtuvo como resultado que, el derecho a la Negociación Colectiva en el Sector Estatal ha evolucionado en el tiempo y pese a ello necesita mejoras para ser realmente efectivo. Se concluye que, la negociación colectiva de los servidores públicos será constitucional siempre y cuando respete el equilibrio presupuestal, Ergo es necesario contar con un Informe Económico Financiero emitido por el MEF que permita a los representantes Sindicales conocer los rangos sobre los cuales es factible su propuesta. Siendo que, será referencial para la elaboración del proyecto del convenio colectivo, para el trato directo de la negociación colectiva y para el arbitraje

    A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
