Propuesta de un método de ontología crítica, composición entre genealogía y análisis estructural de contenido

Objective: to formulate a research method assembled for the analysis of subjectivation processes inserted in power-knowledge relationships, based on the social practices and grammars that constitute them. From there, an analyst is sought in order to read these relationships in cross-sectional research on the here and now, to be used in contemporary discourses and subjectivities. Methodology: a methodological composition was applied between categorical keys of the Foucauldian toolbox, two articulating categories of the harvest itself and data processing techniques of the structural analysis of content. Results: retained categorical keys and others developed from Foucauldian and Deleuzian readings are displayed. An epistemological argumentation is offered to indicate the sense of assembly as a place and function that each of the methodological sources fulfills in the middle of this composition. Finally, some principles of description and symbolic structures for data analysis are indicated. Conclusions: this deployment allows to establish a methodological elaboration, which contributes to the approaches of social practices and subjectivation inserted in the midst of knowledge-power relations, which provides a way to use the Foucauldian toolbox, which in Colombia has traditionally consisted of working with archives; a route to address live speeches from a transversal governmental analysis is achieved.Objetivo: formular un método de investigación ensamblado para el análisis de procesos de subjetivación insertos en relaciones de poder-saber, a partir de las prácticas y gramáticas sociales que los constituyen. Desde allí, se busca una analítica que lea estas relaciones en investigaciones transversales sobre el aquí y el ahora, para emplear en los discursos y subjetividades contemporáneos. Metodología: se aplicó una composición metodológica entre claves categoriales de la caja de herramientas foucaultiana, dos categorías articuladoras de la propia cosecha y técnicas de tratamiento de datos del análisis estructural de contenido. Resultados: se despliegan claves categoriales retomadas y otras desarrolladas a partir de lecturas foucaultianas y deleuzianas. Se ofrece una argumentación epistemológica para indicar el sentido del ensamblaje como lugar y función que cumple cada una de las fuentes metodológicas en medio de esta composición. Finalmente, se señalan algunos principios de descripción y estructuras simbólicas para el análisis de los datos. Conclusiones: este despliegue permite dejar sobre el escenario una elaboración metodológica, la cual aporta a los abordajes de las prácticas sociales y de subjetivación insertas en medio de relaciones de saber-poder, con lo que se propicia una vía para usar la caja de herramientas foucaultianas, que en Colombia ha sido tradicionalmente de trabajo con archivo; se logra una ruta para abordar discursos vivos desde una analítica gubernamental transversal

Discursos que subyacen en la producciónconstitución de subjetividad de un grupo de estudiantes universitarios indígenas

La presente investigación tiene como objetivo comprender los discursos que subyacen en la producción-constitución de subjetividad de un grupo de estudiantes indígenas de la Universidad del Quindío. Son tenidos en cuenta autores como Foucault, para el tema de discursos y prácticas de sí, Dussel para entender el proceso de colonización, Castro para referirse al tema de colonialidad y decolonialidad, Escobar sobre globalización. La categoría de subjetividad abordada desde la perspectiva de Castro, así como Maldonado para hablar de colonialidad del ser. Se usó un enfoque cualitativo con el método de la hermenéutica pluritópica, la cual entiende la diferencia de lo múltiple y hace um diálogo intercultural, usando técnicas como lo son la entrevista a profundidad y talleres de expresión gráfica. El análisis de la información arroja datos en cuanto a las secuelas de la globalización sobre las subjetividades, el papel de agencias socializadoras como la iglesia y la escuela para replicar le pensamiento occidental y la lucha y resistencia por el rescate de lo propio y la identidad pese a los processos del desarrollo y la modernidad

Caracterização de cardiopatias congênitas em Manizales, Colômbia, 2010-2016

Congenital heart defects are the third cause of congenital malformations and one of the main causes of mortality in the neonatal period in the world; they originate from alterations in embryonic development. The incidence is variable; in Colombia, it is estimated that they affect 2 to 3% of live newborns. In 2015, 20.8% of children under the age of five affected with congenital heart defects died from these disorders. This is a descriptive and retrospective study. Data of 252 clinical records of patients diagnosed with congenital heart defect between 2010 and 2016 were included, showing that 56% of this population were female. Acyanotic Congenital Heart Diseases predominated (87%). The highest prevalence was patent ductus arteriosus (35.3%). Doppler echocardiography was used in 98.4% of cases; regarding management, 47.2% of patients were in follow-up, this being more common than medical or surgical alternatives. In conclusion patent ductus arteriosus, ventricular septal defect and interatrial septal defect are the most frequent acyanotic heart diseases in the population under study and they are associated with pulmonary hypertension that require higher follow-up. Tetralogy of Fallot was the most common cyanotic congenital heart disease.Las cardiopatías congénitas son la tercera causa de malformaciones congénitas y una de las principales responsables de la mortalidad en periodo neonatal en el mundo; se originan a partir de alteraciones en el desarrollo embrionario.

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

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

Measurement of prompt open-charm production cross sections in proton-proton collisions at root s=13 TeV

The production cross sections for prompt open-charm mesons in proton-proton collisions at a center-of-mass energy of 13TeV are reported. The measurement is performed using a data sample collected by the CMS experiment corresponding to an integrated luminosity of 29 nb(-1). The differential production cross sections of the D*(+/-), D-+/-, and D-0 ((D) over bar (0)) mesons are presented in ranges of transverse momentum and pseudorapidity 4 < p(T) < 100 GeV and vertical bar eta vertical bar < 2.1, respectively. The results are compared to several theoretical calculations and to previous measurements.Peer reviewe

Reconstruction of signal amplitudes in the CMS electromagnetic calorimeter in the presence of overlapping proton-proton interactions

A template fitting technique for reconstructing the amplitude of signals produced by the lead tungstate crystals of the CMS electromagnetic calorimeter is described. This novel approach is designed to suppress the contribution to the signal of the increased number of out-of-time interactions per beam crossing following the reduction of the accelerator bunch spacing from 50 to 25 ns at the start of Run 2 of the LHC. Execution of the algorithm is sufficiently fast for it to be employed in the CMS high-level trigger. It is also used in the offline event reconstruction. Results obtained from simulations and from Run 2 collision data (2015-2018) demonstrate a substantial improvement in the energy resolution of the calorimeter over a range of energies extending from a few GeV to several tens of GeV.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

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

Search for dark photons in Higgs boson production via vector boson fusion in proton-proton collisions at √s = 13 TeV

A search is presented for a Higgs boson that is produced via vector boson fusion and that decays to an undetected particle and an isolated photon. The search is performed by the CMS collaboration at the LHC, using a data set corresponding to an integrated luminosity of 130 fb−1, recorded at a center-of-mass energy of 13 TeV in 2016–2018. No significant excess of events above the expectation from the standard model background is found. The results are interpreted in the context of a theoretical model in which the undetected particle is a massless dark photon. An upper limit is set on the product of the cross section for production via vector boson fusion and the branching fraction for such a Higgs boson decay, as a function of the Higgs boson mass. For a Higgs boson mass of 125 GeV, assuming the standard model production rates, the observed (expected) 95% confidence level upper limit on the branching fraction is 3.5 (2.8)%. This is the first search for such decays in the vector boson fusion channel. Combination with a previous search for Higgs bosons produced in association with a Z boson results in an observed (expected) upper limit on the branching fraction of 2.9 (2.1)% at 95% confidence level
