Espacio social: creación dialéctica entre campo y habitus

The following exercise start from the assumption of social space—the field of action and influence in which a series of social relations converge, which differ and distribute in the social universe formulated by Pierre Bourdieu—, and the dimensions of the social world when the principles of differentiation and distribution operate, and hypothetically, the set of properties that act from them in the social universe, to give way to practices that describe experiences, both objective and subjective, of resistance anti-violence.El siguiente ejercicio parte del supuesto de espacio social —campo de acción y de influencia en el que confluyen una serie de relaciones sociales, que se diferencian y distribuyen en el universo social formulado por Pierre Bourdieu—, y las dimensiones del mundo social cuando operan los principios de diferenciación y distribución, e hipotéticamente, el conjunto de propiedades que a partir de ellos actúan en el universo social, para dar paso a prácticas que describen experiencias, tanto objetivadas como subjetivadas, de resistencia contra la violencia

Experiencias: trazos de resistencias

El presente escrito, explora diversas posibilidades conceptuales de la resistencia. Intenta describir algunas nociones relacionadas con los ejercicios de control y sometimiento, sujetos (agentes) resistentes, prácticas transformadoras, lucha por el reconocimiento, rupturas, subjetivaciones de experiencias, tejidos del quehacer; y desde allí se arroja a la tarea de contrastar, incluso, dar a conocer cómo ciertos teóricos asumen la resistencia en términos universales y topológicos, otros, simplemente le restan importancia. A través de metodologías histórico-descriptivas, los autores indagan por perspectivas críticas de significación, subjetivación e incorporación de práctica, por cierto, creativas, al momento de resistir. Acuden a la noción de potencia, relacionan la resistencia con la cultura y los horizontes de transformación, para aproximar significados otros, que manifiestan comportamientos no interesados en el poder, pero sí en la autonomía y en la afirmación de sus prácticas de existencia

Cartografía de medios de representación arquitectónica en relación con resultados de aprendizaje. Caso de estudio: Programa de Arquitectura, Universidad Nacional de Colombia, sede Manizales

El proceso de enseñanza-aprendizaje de las técnicas de representación para arquitectos pasa por diferentes etapas en las que se requiere evaluar los resultados de aprendizaje teniendo en cuenta procesos cognitivos y las particularidades de las herramientas tradicionales y contemporáneas que se mezclan para permitir idear, desarrollar y comunicar el proyecto arquitectónico. El siguiente estudio muestra una caracterización de los medios de representación para arquitectura, teniendo en cuenta diversas variables en el proceso proyectual, las cuales se clasifican según el caso de estudio planteado en las asignaturas del área de representación con los estudiantes de Arquitectura de la Universidad Nacional de Colombia en la sede Manizales. El objetivo se enfoca en reconocer la relación de los medios de representación con los resultados de aprendizaje para este programa académico. El método empleado es de carácter cualitativo, a través de reconocimiento de flujos de trabajo e inventario de medios en relación con los resultados de aprendizaje tomados del proyecto presentado para la reforma del programa y el caso de estudio en asignaturas del área de representación. El resultado del estudio presenta una cartografía de medios de representación en arquitectura, que permite navegar e identificar diferentes medios y sus características asociadas a los resultados de aprendizaje según el tipo de cognición, donde se especifican tres tipos de relaciones entre pensamiento concreto, posconcreto y formal y los medios de representación, analógicos, digitales y mixtos.

Geographical and temporal distribution of SARS-CoV-2 clades in the WHO European Region, January to June 2020

We show the distribution of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) genetic clades over time and between countries and outline potential genomic surveillance objectives. We applied three genomic nomenclature systems to all sequence data from the World Health Organization European Region available until 10 July 2020. We highlight the importance of real-time sequencing and data dissemination in a pandemic situation, compare the nomenclatures and lay a foundation for future European genomic surveillance of SARS-CoV-2

Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)

Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality
