Presupuestos municipales, participación y reordenamiento de los espacios políticos

Este artículo aborda los procesos de elaboración de presupuestos municipales en diez provincias del Cusco y Puno, inscribiéndose en el marco del análisis de la tensión burocrática y política entre espacios centrales (Estado) y periferias (ámbitos locales). Así la investigación analiza la participación y posicionamiento político de los distintos actores y muestra que la realización continuada de dichos procesos genera nuevas formas de articulación política y reordenamiento del territorio político local, lo que abre espacios para la representación ciudadana no electoral.This article tackles the processes that characterized the development of municipal budgets in ten provinces of Cusco and Puno. The analysis focuses on the bureaucratic and political tension between the central (the State), and the peripheries (local spaces). The article analyses the participation and political positioning of diverse actors and shows that the continuation of such processes generates new forms of political articulation and reordering of local political territory. This, in turn, opens new spaces for the representation of citizenship as a dimension that is independent of electoral politics

"Comunidade negada". O reconhecimento estatal como constitutivo da comunidade indígena-camponesa. Análise de casos de não reconhecimento na Serra Central do Peru

Las comunidades indígenas fueron “reconocidas” por el Estado peruano en las constituciones de 1920 y 1933. Por el reconocimiento, el Estado concede a las comunidades un status legal, una personería jurídica y sobre todo el amparo estatal a la propiedad colectiva de la tierra, protegiéndola de la expropiación por terceros. Miles de colectivos indígenas detentores de tierras en costa y sierra emprendieron procesos de reconocimiento, ajustándose a la ley y adquiriendo el status de comunidad de indígenas. Estos procesos, no han sido suficientemente analizados para las definiciones existentes sobre “comunidad”. Mostraremos que el proceso de reconocimiento es constitutivo de la institución comunal. Para ello utilizamos un argumento contra-fáctico explorando casos que conducen a la negación de dicho status en cinco solicitudes de reconocimiento de la región central del Perú. Postulamos que el proceso desarrollado administrativamente por el Estado es tan necesario para la definición de comunidad como sus elementos descriptivos y constitutivos. No hay comunidad sin Estado. Estatus jurídico y reconocimiento obtenidos por el cumplimiento de una serie de requisitos explícitos e implícitos, permiten a las comunidades existir y asegurar su continuidad en el tiempo

Propiedad y territorio como (diferentes) bienes comunes. El caso de las tierras de comunidades en la costa norte peruana/Property and territory as (different) common property. Community lands on the northern coast of Peru

 El artículo aborda el problema de la tierra comunal desde la perspectiva de los bienes comunes en los cambiantes y nuevos contextos contemporáneos. A través del análisis de dos comunidades del norte del Perú, muestra los cambios en los contenidos de los bienes comunes como en las organizaciones comunales que los gobiernan. Se desarrolla primero el proceso de formación de la propiedad comunal como bien colectivo, construido en el proceso de defensa de la tierra frente a las haciendas, analizando luego la problemática de la comunidad de Catacaos, sometida a presiones de titulación de tierras agrícolas y de vivienda, obligando a la comunidad a ensayar mecanismos de gobierno territorial. El caso de Sechura ilustra los procesos que se desencadenan cuando la comunidad recibe una renta por la tierra comunal, por derechos de uso del suelo para actividades extractivas, generando un nuevo bien colectivo que es motivo de disputa en el marco del desarrollo de reivindicaciones y defensa territorial que no pasa por la comunidad. Tratamos de mostrar que los cambios en los bienes comunes (hacia la titulación, la rentabilización o la territorialización) desencadenan crisis en las dirigencias comunales que pasan de lógicas de gobierno a lógicas de gobernanza de la tierra. Además, al involucrar otros actores en la disposición sobre los bienes comunes, éstos pueden ser considerados como semi-comunes o semi-públicos.AbstractThis article addresses the problem of communal land from the perspective of common goods in the changing and new contemporary contexts. Through the analysis of two communities in northern Peru, shows the changes in the contents of the common goods as in the communal organizations that govern them. The process of formation of communal property is first developed as a collective good, built in the process of defending the land against the haciendas. Then the case of community of Catacaos, shows how the pressures of titling agricultural land and housing land, are forcing the community to test territorial governance mechanisms. The case of Sechura illustrates the processes that are triggered when the community receives a rent for communal land, for land use rights for extractive activities. That generating a new collective good disputed and a development of claims and defense the territory without the community. We try to show how changes in common goods (towards titling, profitability or territorialization) trigger crises in communal leaderships that go from logics of government to logics of land governance. In addition, by involving other actors in the provision on common goods, these goods can be considered as semi-common or semi-public

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

Measurement of the top quark forward-backward production asymmetry and the anomalous chromoelectric and chromomagnetic moments in pp collisions at √s = 13 TeV

Abstract The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric (d̂ t) and chromomagnetic (μ̂ t) moments have been measured using LHC pp collisions at a center-of-mass energy of 13 TeV, collected in the CMS detector in a data sample corresponding to an integrated luminosity of 35.9 fb−1. The linearized variable AFB(1) is used to approximate the asymmetry. Candidate t t ¯ events decaying to a muon or electron and jets in final states with low and high Lorentz boosts are selected and reconstructed using a fit of the kinematic distributions of the decay products to those expected for t t ¯ final states. The values found for the parameters are AFB(1)=0.048−0.087+0.095(stat)−0.029+0.020(syst),μ̂t=−0.024−0.009+0.013(stat)−0.011+0.016(syst), and a limit is placed on the magnitude of | d̂ t| < 0.03 at 95% confidence level.

An embedding technique to determine ττ backgrounds in proton-proton collision data

An embedding technique is presented to estimate standard model tau tau backgrounds from data with minimal simulation input. In the data, the muons are removed from reconstructed mu mu events and replaced with simulated tau leptons with the same kinematic properties. In this way, a set of hybrid events is obtained that does not rely on simulation except for the decay of the tau leptons. The challenges in describing the underlying event or the production of associated jets in the simulation are avoided. The technique described in this paper was developed for CMS. Its validation and the inherent uncertainties are also discussed. The demonstration of the performance of the technique is based on a sample of proton-proton collisions collected by CMS in 2017 at root s = 13 TeV corresponding to an integrated luminosity of 41.5 fb(-1).Peer reviewe

Measurement of nuclear modification factors of gamma(1S)), gamma(2S), and gamma(3S) mesons in PbPb collisions at root s(NN)=5.02 TeV

The cross sections for ϒ(1S), ϒ(2S), and ϒ(3S) production in lead-lead (PbPb) and proton-proton (pp) collisions at √sNN = 5.02 TeV have been measured using the CMS detector at the LHC. The nuclear modification factors, RAA, derived from the PbPb-to-pp ratio of yields for each state, are studied as functions of meson rapidity and transverse momentum, as well as PbPb collision centrality. The yields of all three states are found to be significantly suppressed, and compatible with a sequential ordering of the suppression, RAA(ϒ(1S)) > RAA(ϒ(2S)) > RAA(ϒ(3S)). The suppression of ϒ(1S) is larger than that seen at √sNN = 2.76 TeV, although the two are compatible within uncertainties. The upper limit on the RAA of ϒ(3S) integrated over pT, rapidity and centrality is 0.096 at 95% confidence level, which is the strongest suppression observed for a quarkonium state in heavy ion collisions to date. © 2019 The Author(s).

Search for Physics beyond the Standard Model in Events with Overlapping Photons and Jets

Results are reported from a search for new particles that decay into a photon and two gluons, in events with jets. Novel jet substructure techniques are developed that allow photons to be identified in an environment densely populated with hadrons. The analyzed proton-proton collision data were collected by the CMS experiment at the LHC, in 2016 at root s = 13 TeV, and correspond to an integrated luminosity of 35.9 fb(-1). The spectra of total transverse hadronic energy of candidate events are examined for deviations from the standard model predictions. No statistically significant excess is observed over the expected background. The first cross section limits on new physics processes resulting in such events are set. The results are interpreted as upper limits on the rate of gluino pair production, utilizing a simplified stealth supersymmetry model. The excluded gluino masses extend up to 1.7 TeV, for a neutralino mass of 200 GeV and exceed previous mass constraints set by analyses targeting events with isolated photons.Peer reviewe
