Sindicatos campesinos y poder estatal en la Bolivia evista (2005-2010)

En Bolivia, el arribo al Estado en el 2005 por parte del Movimiento al Socialismo llevó a inquirir hasta qué punto estábamos en presencia de un Gobierno de los movimientos sociales, en qué medida los núcleos socio-territoriales subalternos, de fuerte matriz sindical, participaban del Gobierno nacional y sus decisiones. Claro está, el umbral de pasaje que instauró el proceso “evista” llevó a la emergencia de nuevas preguntas, marcadas de principio a fin por la evidencia de que las organizaciones sociales han pasado del “subsuelo político” a la arena gubernamental del Estado. A sondear las posibles respuestas sobre el modo en que se desempeñan en el novel escenario se aboca nuestro trabajo. Para dar cuenta de un cuadro que permita visualizar la naturaleza de la coalición de Gobierno, abrimos el lente a las instancias de poder subalternas con el propósito de caracterizar la presencia de los dirigentes sociales en el poder nacional y la lógica decisional del Gobierno masista. Aquí, el análisis se divide en múltiples partes. En una primera damos cuenta de manera minuciosa de la presencia de dirigentes de las organizaciones sociales en el Gobierno, además de enfocar en las nuevas instancias institucionales del poder ejecutivo que tenían por fin darles cabida (le prestamos atención a la composición y al devenir de la Asamblea Constituyente, del poder legislativo, de las áreas ministeriales, etcétera). A continuación, nos adentramos en la dinámica que adquirió el “instrumento político” una vez que Evo Morales accedió a la presidencia, preso de un cambio de proporciones, ya que pasó de desenvolverse en el “subsuelo político” a convertirse en el nuevo partido en función del Gobierno. Por último, presentamos el sistema de decisiones y el tipo de articulación interna de los diferentes sectores del nuevo bloque de poder. La hipótesis principal que subtiende el artículo es que estamos ante la incorporación del democrático sistema sindical boliviano de dirimir disputas, vehiculizar demandas, y producir vínculos políticos, al Estado.In Bolivia, the arrival of the State in 2005 by the Movement Towards Socialism led to inquire if we were in the presence of a government of social movements. Of course, the passage established by the process « evista » led to the emergence of new questions, marked throughout by the evidence that social organizations have gone from « political ground » to the state government arena. To probe the possible answers on how they perform on stage novel tackles our work. To account for a picture that helps illustrate the nature of the coalition government, open the lens to the institutions of power subordinate in order to characterize the presence of social leaders in national power and decisional logic MAS government. In a first part we analize the presence of leaders of social organizations in the government, in addition to focusing on new institutional of executive power that were designed to accommodate them (pay attention to the composition and evolution of the Constituent Assembly, the legislature, ministry, etc.). Then we move into the dynamics acquired « instrumento político » once Evo Morales became president, prisoner of a change of proportions, as passed to function in the « political underground » to become the new party in government function. Finally, we present the system and the type of decisions internal articulation of the different sectors of the new power block. The main assumption that underlies the article is that this is the incorporation of the democratic system of settling disputes of Bolivian unions to the State.Fil: Fornillo, Bruno Martín.

El control de las unidades reguladoras: ¿cómo y quienes efectúan dicho control en nuestro derecho positivo y en el derecho comparado?

El presente estudio tiene por objeto el examen del contralor sobre las Unidades reguladoras, tanto a nivel de derecho positivo nacional como de derecho comparado, recogiendo las experiencias de países como Argentina y Brasil. En merito a ello, se comenzará por un análisis de la Teoría del Control y de la Responsabilidad, las cuales tienen plena vigencia respecto de las Unidades Reguladoras.Dicho control se ejerce en nuestro derecho positivo, ya sea desde el ámbito del propio Poder Ejecutivo a través de la Auditoria Interna de la Nación (A.I.N) en su carácter de Unidad Ejecutora del Ministerio de Economía y Finanzas, como desde fuera de dicho sistema orgánico a través del Tribunal de Cuentas de la República (T.C.R). En consecuencia, se abordaran dos casos prácticos de actuaciones practicadas por dichos organismos en las unidades reguladoras de nuestro país: la U.R.S.E.C. y la U.R.S.E.A. En última instancia, y modo de conclusión, se analizará cómo estas Agencias han sido consagradas en el derecho comparado y cuáles son los mecanismos de control existentes en los mismos

Nusinersen Induces Disease-Severity-Specific Neurometabolic Effects in Spinal Muscular Atrophy

Intrathecal delivery of Nusinersen-an antisense oligonucleotide that promotes survival motor neuron (SMN) protein induction-is an approved therapy for spinal muscular atrophy (SMA). Here, we employed nuclear magnetic resonance (NMR) spectroscopy to longitudinally characterize the unknown metabolic effects of Nusinersen in the cerebrospinal fluid (CSF) of SMA patients across disease severity. Modulation of amino acid metabolism is a common denominator of biochemical changes induced by Nusinersen, with distinct downstream metabolic effects according to disease severity. In severe SMA1 patients, Nusinersen stimulates energy-related glucose metabolism. In intermediate SMA2 patients, Nusinersen effects are also related to energy homeostasis but involve ketone body and fatty acid biosynthesis. In milder SMA3 patients, Nusinersen mainly modulates amino acid metabolism. Moreover, Nusinersen modifies the CSF metabolome of a more severe clinical group towards the profile of untreated SMA patients with milder disease. These findings reveal disease severity-specific neurometabolic signatures of Nusinersen treatment, suggesting a selective modulation of peripheral organ metabolism by this CNS-directed therapy in severe SMA patients

Measurement of the cross-section and charge asymmetry of WW bosons produced in proton-proton collisions at s=8\sqrt{s}=8 TeV with the ATLAS detector

This paper presents measurements of the $W^+ \rightarrow \mu^+\nu$ and $W^- \rightarrow \mu^-\nu$ cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the 1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured with an uncertainty between 0.002 and 0.003. The results are compared with predictions based on next-to-next-to-leading-order calculations with various parton distribution functions and have the sensitivity to discriminate between them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables, submitted to EPJC.

Search for new phenomena in final states with an energetic jet and large missing transverse momentum in pp collisions at √ s = 8 TeV with the ATLAS detector

Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb−1 of √ s = 8 TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with pT > 120 GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between Emiss T > 150 GeV and Emiss T > 700 GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with either large extra spatial dimensions, pair production of weakly interacting dark matter candidates, or production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presente

Search for direct stau production in events with two hadronic tau-leptons in root s=13 TeV pp collisions with the ATLAS detector

A search for the direct production of the supersymmetric partners ofτ-leptons (staus) in final stateswith two hadronically decayingτ-leptons is presented. The analysis uses a dataset of pp collisions corresponding to an integrated luminosity of139fb−1, recorded with the ATLAS detector at the LargeHadron Collider at a center-of-mass energy of 13 TeV. No significant deviation from the expected StandardModel background is observed. Limits are derived in scenarios of direct production of stau pairs with eachstau decaying into the stable lightest neutralino and oneτ-lepton in simplified models where the two staumass eigenstates are degenerate. Stau masses from 120 GeV to 390 GeV are excluded at 95% confidencelevel for a massless lightest neutralino

Search for chargino-neutralino production with mass splittings near the electroweak scale in three-lepton final states in √s=13 TeV pp collisions with the ATLAS detector

A search for supersymmetry through the pair production of electroweakinos with mass splittings near the electroweak scale and decaying via on-shell W and Z bosons is presented for a three-lepton final state. The analyzed proton-proton collision data taken at a center-of-mass energy of √s=13  TeV were collected between 2015 and 2018 by the ATLAS experiment at the Large Hadron Collider, corresponding to an integrated luminosity of 139  fb−1. A search, emulating the recursive jigsaw reconstruction technique with easily reproducible laboratory-frame variables, is performed. The two excesses observed in the 2015–2016 data recursive jigsaw analysis in the low-mass three-lepton phase space are reproduced. Results with the full data set are in agreement with the Standard Model expectations. They are interpreted to set exclusion limits at the 95% confidence level on simplified models of chargino-neutralino pair production for masses up to 345 GeV

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

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

Combined measurement of differential and total cross sections in the H → γγ and the H → ZZ* → 4ℓ decay channels at s=13 TeV with the ATLAS detector

A combined measurement of differential and inclusive total cross sections of Higgs boson production is performed using 36.1 fb−1 of 13 TeV proton–proton collision data produced by the LHC and recorded by the ATLAS detector in 2015 and 2016. Cross sections are obtained from measured H→γγ and H→ZZ*(→4ℓ event yields, which are combined taking into account detector efficiencies, resolution, acceptances and branching fractions. The total Higgs boson production cross section is measured to be 57.0−5.9 +6.0 (stat.) −3.3 +4.0 (syst.) pb, in agreement with the Standard Model prediction. Differential cross-section measurements are presented for the Higgs boson transverse momentum distribution, Higgs boson rapidity, number of jets produced together with the Higgs boson, and the transverse momentum of the leading jet. The results from the two decay channels are found to be compatible, and their combination agrees with the Standard Model predictions

Search for High-Mass Resonances Decaying to τν in pp Collisions at √s=13 TeV with the ATLAS Detector

A search for high-mass resonances decaying to τν using proton-proton collisions at √s=13 TeV produced by the Large Hadron Collider is presented. Only τ-lepton decays with hadrons in the final state are considered. The data were recorded with the ATLAS detector and correspond to an integrated luminosity of 36.1 fb−1. No statistically significant excess above the standard model expectation is observed; model-independent upper limits are set on the visible τν production cross section. Heavy W′ bosons with masses less than 3.7 TeV in the sequential standard model and masses less than 2.2–3.8 TeV depending on the coupling in the nonuniversal G(221) model are excluded at the 95% credibility level
