    Objeto: El documento pretende fortalecer las estructuras de análisis identificando los aspectos que dentro de una exploración bibliográfica y bajo el criterio de los académicos sean considerados relevantes para la valoración de logros y evolución de la organización en relación a su estrategia de sostenibilidad. Diseño/metodología/enfoque: Metodología de investigación cualitativa. El estudio parte de una retrospectiva bibliográfica de 25 años, con base en las interpretaciones realizadas por los autores de 90 artículos en el ámbito de la gestión de la sostenibilidad; de esta manera se establece un consenso de opinión respecto a aspectos de marcado interés que debe contener un instrumento de enfoque analítico que permita ajustar la estrategia de sostenibilidad de la organización. Aportaciones y resultados: Los contextos que alcanzaron un mayor consenso y presentan un marcado interés para los autores son los que asocian aspectos relacionados con los elementos de control necesarios para que exista una adecuada comprobación, inspección, fiscalización o intervención en los procesos de gestión de la sostenibilidad, e integración dentro de la estructura operativa de la empresa como un elemento de cohesión entre los mecanismos de gestión corporativa. Limitaciones: Los datos cualitativos son una muestra representativa de artículos en un idioma específico, los cuales fueron extractados de dos bases de datos bibliográficos (Scopus e ISI Web Knowledge). Aunque existe un amplio y variado catálogo de artículos en diferentes idiomas y en diversas bases de datos, es una exploración exhaustiva que está más allá del alcance de este estudio. Implicaciones prácticas: El estudio pone de relieve la importancia de asociar los datos recogidos de los diferentes Mecanismos de Gestión Corporativa (MGC) que están directamente involucrados en la estrategia de sostenibilidad, así como los retos que implica el uso de dichos datos para ampliar los beneficios que esta área aporta a la relación de sustentabilidad local-global. Implicaciones sociales: El estudio propone la implementación del cuadro de mando en las organizaciones, como herramienta de coordinación horizontal para los mecanismos de gestión corporativa; de esta manera se proporciona a los administradores una mirada global de la organización desde diferentes perspectivas; su uso como soporte a la gestión es de alto valor, ya que permite controlar de forma continua si una empresa va a alcanzar los resultados definidos dentro de un plan estratégico de sostenibilidad. Originalidad / Valor añadido: El estudio ofrece una visión de los aspectos de gestión que de forma iterativa siguen siendo base de estudio por académicos, y que mediante una re-asociación de ideas permite la generación de una propuesta con base en algunos consensos identificados.Purpose: The paper aims to strengthen the structures of analysis by identifying relevant aspects that within a bibliographic exploration and under academic criteria are considered relevant to assessment of corporate achievements and evolution in relation to its sustainability strategy. Design/methodology: Qualitative research methodology. The paper is a literature retrospective of 25 years, based on interpretations made by the authors of 90 articles in the field of sustainability management; thus a consensus of opinion is established in relation to aspects of strong interest in order to develop an instrument with analytical approach and strategy. Findings: The contexts that reached greater consensus and have a strong interest for authors are those aspects associated with required elements of "Control" for a proper check, inspection, supervision or intervention in sustainability management processes, and "Integration" within the corporate operational structure as an element of cohesion between corporate management mechanisms. Research limitations/implications: Qualitative data are a representative sample of articles in a single language, which were extracted from two bibliographic databases (Scopus and ISI Web Knowledge). Although there is a wide and varied catalogue of articles in different languages and in different databases, it is an exhaustive exploration that goes beyond the scope of this study. Practical implications: The paper highlights the importance of linking data collected from different corporate management mechanism which are directly involved in the sustainability strategy and challenges of using such data to extend the benefits this association brings to the relationship of local-global sustainability. Social implications: The paper propose the implementation of a scorecard to organizations as horizontal coordination tool for corporate management mechanisms; thus it's provided to managers a global view of the organization from different perspectives; its use as management support has high value, since allowing continuously monitor whether a company will achieve defined outcomes within a strategic sustainability plan. Originality/value: The paper provides an overview of management aspects that remain iteratively as base of research studies by scholars and that through a reassociation of ideas allows the setting up a proposal regarding at some consensus identified.Peer Reviewe

    Anticoagulant selection in relation to the SAMe-TT2R2 score in patients with atrial fibrillation. the GLORIA-AF registry

    Aim: The SAMe-TT2R2 score helps identify patients with atrial fibrillation (AF) likely to have poor anticoagulation control during anticoagulation with vitamin K antagonists (VKA) and those with scores >2 might be better managed with a target-specific oral anticoagulant (NOAC). We hypothesized that in clinical practice, VKAs may be prescribed less frequently to patients with AF and SAMe-TT2R2 scores >2 than to patients with lower scores. Methods and results: We analyzed the Phase III dataset of the Global Registry on Long-Term Oral Antithrombotic Treatment in Patients with Atrial Fibrillation (GLORIA-AF), a large, global, prospective global registry of patients with newly diagnosed AF and ≥1 stroke risk factor. We compared baseline clinical characteristics and antithrombotic prescriptions to determine the probability of the VKA prescription among anticoagulated patients with the baseline SAMe-TT2R2 score >2 and ≤ 2. Among 17,465 anticoagulated patients with AF, 4,828 (27.6%) patients were prescribed VKA and 12,637 (72.4%) patients an NOAC: 11,884 (68.0%) patients had SAMe-TT2R2 scores 0-2 and 5,581 (32.0%) patients had scores >2. The proportion of patients prescribed VKA was 28.0% among patients with SAMe-TT2R2 scores >2 and 27.5% in those with scores ≤2. Conclusions: The lack of a clear association between the SAMe-TT2R2 score and anticoagulant selection may be attributed to the relative efficacy and safety profiles between NOACs and VKAs as well as to the absence of trial evidence that an SAMe-TT2R2-guided strategy for the selection of the type of anticoagulation in NVAF patients has an impact on clinical outcomes of efficacy and safety. The latter hypothesis is currently being tested in a randomized controlled trial.

    MUSiC : a model-unspecific search for new physics in proton-proton collisions at root s=13TeV

    Get PDF
    Results of the Model Unspecific Search in CMS (MUSiC), using proton-proton collision data recorded at the LHC at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb(-1), are presented. The MUSiC analysis searches for anomalies that could be signatures of physics beyond the standard model. The analysis is based on the comparison of observed data with the standard model prediction, as determined from simulation, in several hundred final states and multiple kinematic distributions. Events containing at least one electron or muon are classified based on their final state topology, and an automated search algorithm surveys the observed data for deviations from the prediction. The sensitivity of the search is validated using multiple methods. No significant deviations from the predictions have been observed. For a wide range of final state topologies, agreement is found between the data and the standard model simulation. This analysis complements dedicated search analyses by significantly expanding the range of final states covered using a model independent approach with the largest data set to date to probe phase space regions beyond the reach of previous general searches.Peer reviewe

    Search for long-lived particles decaying to jets with displaced vertices in proton-proton collisions at root s=13 Te V

    Get PDF
    A search is presented for long-lived particles produced in pairs in proton-proton collisions at the LHC operating at a center-of-mass energy of 13 TeV. The data were collected with the CMS detector during the period from 2015 through 2018, and correspond to a total integrated luminosity of 140 fb(-1). This search targets pairs of long-lived particles with mean proper decay lengths between 0.1 and 100 mm, each of which decays into at least two quarks that hadronize to jets, resulting in a final state with two displaced vertices. No significant excess of events with two displaced vertices is observed. In the context of R-parity violating supersymmetry models, the pair production of long-lived neutralinos, gluinos, and top squarks is excluded at 95% confidence level for cross sections larger than 0.08 fb, masses between 800 and 3000 GeV, and mean proper decay lengths between 1 and 25 mm.Peer reviewe

    Search for top squark production in fully hadronic final states in proton-proton collisions at root s=13 TeV

    A search for production of the supersymmetric partners of the top quark, top squarks, is presented. The search is based on proton-proton collision events containing multiple jets, no leptons, and large transverse momentum imbalance. The data were collected with the CMS detector at the CERN LHC at a center-of-mass energy of 13 TeV, and correspond to an integrated luminosity of 137 fb(-1). The targeted signal production scenarios are direct and gluino-mediated top squark production, including scenarios in which the top squark and neutralino masses are nearly degenerate. The search utilizes novel algorithms based on deep neural networks that identify hadronically decaying top quarks and W bosons, which are expected in many of the targeted signal models. No statistically significant excess of events is observed relative to the expectation from the standard model, and limits on the top squark production cross section are obtained in the context of simplified supersymmetric models for various production and decay modes. Exclusion limits as high as 1310 GeVare established at the 95% confidence level on the mass of the top squark for direct top squark production models, and as high as 2260 GeV on the mass of the gluino for gluino-mediated top squark production models. These results represent a significant improvement over the results of previous searches for supersymmetry by CMS in the same final state.Peer reviewe

    Measurement of the W gamma Production Cross Section in Proton-Proton Collisions at root s=13 TeV and Constraints on Effective Field Theory Coefficients

    Get PDF
    A fiducial cross section for W gamma production in proton-proton collisions is measured at a center-of-mass energy of 13 TeV in 137 fb(-1) of data collected using the CMS detector at the LHC. The W -> e nu and mu nu decay modes are used in a maximum-likelihood fit to the lepton-photon invariant mass distribution to extract the combined cross section. The measured cross section is compared with theoretical expectations at next-to-leading order in quantum chromodynamics. In addition, 95% confidence level intervals are reported for anomalous triple-gauge couplings within the framework of effective field theory.Peer reviewe
