La teoría de la verdad en Ser y Tiempo

Este trabajo explora la teoría de la verdad presentada pr Martin Heidegger en su obra Ser y Tiempo. Esta teoría es situada en relación no solo con la tradición filosófica sino con la filosofía anglosajona contemporánea. La mencionada teoría de la verdad es defendida como un marco más sólido y amplio en el que comprender no solo fenómenos como la verdad sino también la representación y la referencia.This work explores the theory of truth on Martin Heidegger's Being and Time. This theory is placed not just as related with the philosophical tradition but with contemporary anglosaxon philosophy also. It shows that Heidegger's theory of truth is a wider and stronger framework for understanding not just Truth, but phenomena like reference or representation

A critical study of experimentation in development economics

¿Por qué son tan populares las RCT en la economía del desarrollo? No se trata simplemente de que ofrezcan un buen método para estimar el impacto causal de una intervención y, por tanto, que ofrezcan evidencia sólida en lo que respecta a la ejecución de políticas públicas. Por un lado, la evidencia que proveen, si bien es sólida, no contribuye por sí sola al desarrollo teórico de envergadura que requiere la investigación científica, y por otro lado hay otros tipos de investigación que pueden explorar aspectos interesantes y enriquecedores de la economía del desarrollo que, no obstante, son opacados por la popularidad de las RCT como gold standard de la investigación. Ahora bien, su popularidad puede ser comprendida si se estudia la historia de la economía del desarrollo y el conjunto de relaciones sociales que vinculan a los distintos actores que financian, implementan y son objeto de estudio de las RCT. Esto permite, finalmente, ofrecer una caracterización de qué es y qué sucede hoy con el desarrollo.Why are RCTs so popular in development economics? It is not simply that they offer a good method to estimate the causal impact of an intervention and, therefore, that they offer solid evidence regarding the execution of public policies. On the one hand, the evidence they provide, while solid, does not by itself contribute to the far-reaching theoretical development that scientific research requires, and on the other hand there are other types of research that can explore interesting and enriching aspects of development economics that, nonetheless, are overshadowed by the popularity of RCTs as a research gold standard. However, their popularity can be understood by studying the history of development economics and the set of social relations that links the different actors that finance, implement and are the subject of study by RCTs. This allow us to, finally, offer a characterization of what is and what is happening nowadays with development.MaestríaEconomía del desarroll

Effects of pre-operative isolation on postoperative pulmonary complications after elective surgery: an international prospective cohort study an international prospective cohort study

We aimed to determine the impact of pre-operative isolation on postoperative pulmonary complications after elective surgery during the global SARS-CoV-2 pandemic. We performed an international prospective cohort study including patients undergoing elective surgery in October 2020. Isolation was defined as the period before surgery during which patients did not leave their house or receive visitors from outside their household. The primary outcome was postoperative pulmonary complications, adjusted in multivariable models for measured confounders. Pre-defined sub-group analyses were performed for the primary outcome. A total of 96,454 patients from 114 countries were included and overall, 26,948 (27.9%) patients isolated before surgery. Postoperative pulmonary complications were recorded in 1947 (2.0%) patients of which 227 (11.7%) were associated with SARS-CoV-2 infection. Patients who isolated pre-operatively were older, had more respiratory comorbidities and were more commonly from areas of high SARS-CoV-2 incidence and high-income countries. Although the overall rates of postoperative pulmonary complications were similar in those that isolated and those that did not (2.1% vs 2.0%, respectively), isolation was associated with higher rates of postoperative pulmonary complications after adjustment (adjusted OR 1.20, 95%CI 1.05–1.36, p = 0.005). Sensitivity analyses revealed no further differences when patients were categorised by: pre-operative testing; use of COVID-19-free pathways; or community SARS-CoV-2 prevalence. The rate of postoperative pulmonary complications increased with periods of isolation longer than 3 days, with an OR (95%CI) at 4–7 days or ≥ 8 days of 1.25 (1.04–1.48), p = 0.015 and 1.31 (1.11–1.55), p = 0.001, respectively. Isolation before elective surgery might be associated with a small but clinically important increased risk of postoperative pulmonary complications. Longer periods of isolation showed no reduction in the risk of postoperative pulmonary complications. These findings have significant implications for global provision of elective surgical care.
