La dialéctica de la regularización barrial en Bogotá: del urbanismo incompleto a la consolidación

El estudio de la producción habitacional popular va más allá de la discusión común de la informalidad como la contraparte de la formalidad. En este sentido, en el artículo se discute la importancia de la regularización barrial como parte de las políticas urbanas reactivas a la luz de la acentuada informalidad urbana en las metrópolis latinoamericanas. Para el caso particular de Bogotá, el análisis de la regularización barrial indaga por los vínculos entre la informalidad urbana y el modo de vida popular considerando una discusión sobre el derecho a la ciudad para, luego, realizar un balance de la eficacia de las políticas de vivienda basadas en el mercado formal como antesala al análisis de los resultados de los programas de regularización barrial. Finalmente se sugieren algunas líneas de acción al respecto de las políticas urbanas estatales.The study of popular housing production goes beyond the common discussion of the informality as a counterpart of formality. In this way, the article discusses the value of neighborhood regularization as part of reactive urban policies considering the outstanding urban informality in Latin American metropolises. In particular, for Bogotá, the analysis of neighborhood regularization inquires for the links between urban formality and the popular way of life, taking into account a discussion about the right of the city, and then to take stock of the effectiveness of the policies of Housing based on the formal market as a prelude to the analysis of the results of neighborhood regularization programs. Finally, we suggest some lines of action regarding the state urban policies

El ciclo mortal de los habitantes de calle en Bogotá. Teorías, olvidos, políticas y desenlaces fatales

El fenómeno de la habitación de la calle es universal, si bien se presenta con mayor intensidad en las metrópolis tercermundistas. Un estado del arte reconstruido desde una perspectiva pluridisciplinar permite advertir ciertos olvidos acerca de sus determinantes. En este artículo se plantea la hipótesis de que la entrada a la habitación en la calle en Bogotá se realiza a cualquier edad y que, cuando ello ocurre, se anticipa la etapa de desesperanza con la que se inicia el ciclo mortal de las personas

O ciclo mortal dos moradores de rua em Bogotá. Teorias, esquecimento, políticas e resultados fatais

The deadly cycle of street dwellers in Bogotá Theories, forgetting, comparisons, policies and fatal outcomes The phenomenon of street homelessness is universal, although it occurs with greater intensity in the Third World metropolises. A state of the art reconstructed from a multidisciplinary perspective allows to notice certain forgetfulness about its determinants. This article hypothesizes that the entrance to habitability on the street in Bogotá takes place at any age, and that when this happens, the stage of despair with which the mortal cycle begins is anticipated.El fenómeno de la habitación de la calle es universal, si bien se presenta con mayor intensidad en las metrópolis tercermundistas.

In this paper we extend some previous results on both notions to sequences of operators, C-0-semigroups, C-regularized semigroups, and alpha-timesintegrated semigroups on Frechet spaces. We also add a study of rescaled distributionally chaotic C-0-semigroups. Some examples are provided to illustrate all these results.The first and fourth authors are supported in part by MEC Project MTM2010-14909, MTM2013-47093-P, and Programa de Investigacion y Desarrollo de la UPV, Ref.

Elective Cancer Surgery in COVID-19-Free Surgical Pathways During the SARS-CoV-2 Pandemic: An International, Multicenter, Comparative Cohort Study.

PURPOSE: As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19-free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS: This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a COVID-19-free surgical pathway (complete segregation of the operating theater, critical care, and inpatient ward areas) or no defined pathway (incomplete or no segregation, areas shared with patients with COVID-19). The primary outcome was 30-day postoperative pulmonary complications (pneumonia, acute respiratory distress syndrome, unexpected ventilation). RESULTS: Of 9,171 patients from 447 hospitals in 55 countries, 2,481 were operated on in COVID-19-free surgical pathways. Patients who underwent surgery within COVID-19-free surgical pathways were younger with fewer comorbidities than those in hospitals with no defined pathway but with similar proportions of major surgery. After adjustment, pulmonary complication rates were lower with COVID-19-free surgical pathways (2.2% v 4.9%; adjusted odds ratio [aOR], 0.62; 95% CI, 0.44 to 0.86). This was consistent in sensitivity analyses for low-risk patients (American Society of Anesthesiologists grade 1/2), propensity score-matched models, and patients with negative SARS-CoV-2 preoperative tests. The postoperative SARS-CoV-2 infection rate was also lower in COVID-19-free surgical pathways (2.1% v 3.6%; aOR, 0.53; 95% CI, 0.36 to 0.76). CONCLUSION: Within available resources, dedicated COVID-19-free surgical pathways should be established to provide safe elective cancer surgery during current and before future SARS-CoV-2 outbreaks
