Epidemiological Information

The COVID-19 pandemic had an uneven development in different countries. In Argentina, the pandemic began in march 2020 and, during the first 3 months, the vast majority of cases were concentrated in a densely populated region that includes the city of Buenos Aires (country capital) and the Greater Buenos Aires area that surrounds it. This work focuses on the spread of COVID-19 between June and November 2020 in Greater Buenos Aires. Within this period of time there was no vaccine, basically only the early wild strain of SARS-CoV-2 was present, and the official restriction and distancing measures in this region remained more or less constant. Under these particular conditions, the incidences show a sharp rise from June 2020 and begin to decrease towards the end of August until the end of November 2020. In this work we study, through mathematical modelling and available epidemiological information, the spread of COVID-19 in this region and period of time. We show that a coherent explanation of the evolution of incidences can be obtained assuming that only a minority fraction of the population got involved in the spread process, so that the incidences decreased as this group of people was becoming immune. The observed evolution of the incidences could then be a consequence at the population level of lasting immunity conferred by SARS-CoV-2.

The City

This chapter charts how canonic repertories evolved in very different forms in New York City during the nineteenth century. The unstable succession of entrepreneurial touring troupes that visited the city adapted both repertory and individual pieces to the audience’s taste, from which there emerged a major theater, the Metropolitan Opera, offering a mix of German, Italian, and French works. The stable repertory in place there by 1910 resembles to a considerable extent that performed in the same theater today. Indeed, all of the twenty-five operas most often performed between 1883 and 2015 at the Metropolitan Opera were written before World War I. The repertory may seem haphazard in its diversity, but that very condition proved to be its strength in the long term. This chapter is paired with Benjamin Walton’s “Canons of real and imagined opera: Buenos Aires and Montevideo, 1810–1860.”

ObjectiveTo summarise the unfolding of the COVID-19 epidemic among slum dwellers and different social strata in the city of Buenos Aires during the first 20 weeks after the first reported case.DesignObservational study using a time-series analysis. Natural experiment in a big city.SettingPopulation of the city of Buenos Aires and the integrated health reporting system records of positive RT-PCR for COVID-19 tests.ParticipantsRecords from the Argentine Integrated Health Reporting System for all persons with suspected and RT-PCR-confirmed diagnosis of COVID-19 between 31 January and 14 July 2020.OutcomesTo estimate the effects of living in a slum on the standardised incidence rate of COVID-19, corrected Poisson regression models were used. Additionally, the impact of socioeconomic status was performed using an ecological analysis at the community level.ResultsA total of 114 052 people were tested for symptoms related with COVID-19. Of these, 39 039 (34.2%) were RT-PCR positive. The incidence rates for COVID-19 towards the end of the 20th week were 160 (155 to 165) per 100 000 people among the inhabitants who did not reside in the slums (n=2 841 997) and 708 (674 to 642) among slums dwellers (n=233 749). Compared with the better-off socioeconomic quintile (1.00), there was a linear gradient on incidence rates: 1.36 (1.25 to 1.46), 1.61 (1.49 to 1.74), 1.86 (1.72 to 2.01), 2.94 (2.74 to 3.16) from Q2 to Q5, respectively. Slum dwellers were associated with an incidence rate of 14.3 (13.4 to 15.4).ConclusionsThe distribution of the epidemic is socially conditioned. Slum dwellers are at a much higher risk than the rest of the community. Slum dwellers should not be considered just another risk category but an entirely different reality that requires policies tailored to their needs.

Immigration And Crime

Between the late nineteenth and early twentieth centuries, the City of Buenos Aires (Argentina) had a significant demographic growth due to the strong weight of the migratory component. This article focuses on describing the theoretical frameworks deployed by criminologists and related experts to “racialize” the links between immigration and crime in Archivos de Criminología, Medicina Legal, Psiquiatría y Ciencias Afines, a journal published between 1902 and 1913. In so doing, and inspired by the Southern criminology proposals and reflections, I propose to analyze the criminological travels related to the Italian Positive School, to detail the grounds the thematic links between immigration and crime were based on and, in turn, to empirically illustrate different arguments around criminology as a Northern discipline.

Traditional Roles

This article expands on current conceptualizations and applications of precarity by exploring the everyday socio-spatial complexities of migrant squatters living in informal hotels in the center of Buenos Aires, Argentina. Through ethnographic methods, this research investigates squatters’ practices of negotiating access to shared domestic spaces and resources, while experiencing long-term waiting for eviction from their home and potentially from the city center. Employing a cultural geographies approach, this work is concerned with understanding the ways in which precarity is routinely experienced in the micro-spaces of everyday life. Precarity is examined in its temporal and spatial manifestations, with particular emphasis on gendered experiences and home-making practices. Moving through daily spaces and routine situations, I document how precarity is embedded in the mundane tasks of the domestic, and as a result, unevenly impacts women whose traditional roles as mothers and caretakers mean that they are often at the fore of place-making practices and responsibilities.
