We present an analytical reflection on our experience as adscriptas a la investigación, a term used in Spanish to describe the role of those who volunteer as students to be in an apprenticeship relationship with experienced professors-researchers at our public university (School of Humanities) in the metropolitan area sorrounding the city of Buenos Aires. We have analyzed and written our piece in two voices, as we are both apprentices. Methodologically, we start from our work logs, audio recordings and photographs to make an analytical description of the assignment, which is divided into three sections: the place of others in the construction of knowledge, word in dispersion and resistance, and spaces and bodies that communicate in themselves. Our reflection accounts for the learning and transformation opportunities generated from the implementation of a new pedagogical practice for us. Thus, we observe that a space was created in connection with others that favored parity, horizontal communication, and, together with it, the collective construction of new knowledge based on local epistemologies.

The agribusiness model involved the expansion of crops and the application of a technological package that has generated the use of millions of liters of agrochemicals, which exposes rural populations to simultaneous or sequenced exposure to products, which seriously affect health and the environment. These externalities are reflected in the bodyterritory of women who inhabit and/or transit rural spaces, and suffer from daily land dispossession, labor exploitation and deterioration of their health as a result of the drift of agrochemicals. In this paper I intend to make visible the struggle of women, teachers, who gave birth to the Federal Network of Teachers for Life in San Andrés de Giles (Buenos Aires province) in 2017; an environmental group that denounces these problems, promotes actions to protect the environment and the rights of students and rural families. The methodology includes the analysis of journalistic sources, fieldwork and the development of semi-structured interviews in the territory of San Andrés de Giles. [ABSTRACT FROM AUTHOR]

The forms in which Environmental Education (EE) is included in the curriculum are a long-standing concern in the Latin American didactic field. In this paper we analyse the current curricular designs for the Basic Secondary School in the province of Buenos Aires, Argentina. Although in hierarchically superior regulations (Provincial Education Law and General Framework of Curricular Policy), EE is based on critical and ethnographic perspectives, it has an uneven transversal presence in the curricular designs. Some subjects present an empty EE curriculum, while others show fragmentary and contradictory perspectives. Only in Social Sciences, Geography and Citizenship Building is there a critical and ethnographic vision, linked to contemporary environmental conflicts. From Geography we recovered the experiential dimension and the enjoyment of the environment as a contribution to the pedagogies of environmental conflict and to the ongoing implementation the new national EE regulations.

Considering the increase in housing tenants (inquilinización) and financialization in Latin America, this paper explores the emergence of short-term rentals in the City of Buenos Aires, as a growing trend of housing commodification, barely incorporated into the agenda of urban studies in Latin America. To do so, we take the case of Airbnb and examined four basic dimensions to characterize the phenomenon: quantity and evolution of offers, spatial distribution, housing prices and types of owners, then comparing them with the long term rental market. Results show that short term rental shows sustained growth both over time and territory; it is a real estate market segment which is operated by concentrated and intermediary actors. Due to the low occupancy rate of the properties, the rent obtained is currently lower than in the long-term rental market. However, the post-pandemic context (still in the process of recovery) and other significant non-economic factors must be considered when interpreting these results. The paper concludes by proposing future possibilities of advance in the research of the phenomenon in Argentina. [ABSTRACT FROM AUTHOR]

This paper deals with the role of a public university located in the second cordon of Greater Buenos Aires: The National University of José C. Paz (unpaz). The objective of the work is to address the experience of unpaz, its actions, interventions and articulations with the different levels of statehood in the context of the pandemic in José C. Paz, one of the municipalities with the highest levels of impoverishment and vulnerability. On the one hand, the support and accompaniment strategies of the university to the student community are addressed in order to promote the continuity of the course, and on the other, the specific actions in socio-sanitary matters aimed at the entire La Paz community. Thus, the university is understood not only as a physical installation in a place, but as a central component as an urban facility and a social agent with implications for the local territory and in relation to its community.

This paper focuses on the Programa de Crédito Argentino del Bicentenario para la Vivienda Única Familiar (pro.cre.ar) on implementation processes, created in 2012 by the National Government. pro.crear programm generated expectations among citizens and different economic sectors. However, it got around several obstacles in its implementation and some of its lines were more effective than others. This paper offers a "bottom-up" view that recovers experiences and residential trayectories of Program beneficiaries. Semi-structured interviews were conducted with beneficiaries and successful bidders (who could effectively access and use the credit) of pro.cre.ar (2012-2015) in the Municipality of La Matanza, province of Buenos Aires, Argentina.

The aim of this paper is to analyze the processes of class formation and workers’ organization in the cities of Rosario and Santa Fe, Argentina, between 1870 and the first decade of the twentieth century. An analytical perspective of local-regional and comparative history was chosen, seeking to observe how these processes operated between both cities beyond the links with the Federal Capital, paying attention to the ideological current that hegemonized the working-class world at that time, anarchism, as well as the workers’ federations. A heuristic analysis and the triangulation of workers’ sources with official documents were carried out and, through the comparative method, an attempt is made to account for the close links and repertoires of collective action shared and used by the workers in their process of union organization, showing the regional organizational capacity beyond the links with Buenos Aires.

This paper analyzes, from a glotopolitical perspective, the establishment and functioning of a Spanish-Putonghua bilingual public school in the city of Buenos Aires. This institution and its implementation demonstrate a concern for the educational inclusion of Chinese migrants and their descendants, as well as for the preservation and learning of the immigration language. Throughout this article, we will show how Putonghua is constructed both as a language of instruction and as an "object language" in legal regulations, classes, and in the speeches of officials. We argue that the motivation underlying the creation of this school is the increasing importance that Putonghua has gained globally in recent years. [ABSTRACT FROM AUTHOR]

In this paper, we study how the intentionality to propose an experimental situation in a science lesson was mobilized. This situation initiated a didactic sequence about light that was implemented in different elementary classrooms (belonging to a socioeducational program from the City of Buenos Aires) and was conceived in a working group where teachers and researchers collaborate. We aim to explore the potentiality of this collaborative modality to promote the construction of ideas on teaching and learning science. We present a case study and we focus on the interactions between the different positions of the collaborative group members as they were involved in the co-design, implementation, and analysis of the sequence. We identified that, initially, the group discussions were centered on the material aspects of the lesson design; but, after the first implementations, the shared reflection about the classroom scenes made it possible to problematize the teachers' interventions, the interpretation of the students' ideas and the assessment of alternatives on how to promote student engagement. This motivated modifications in further implementations and redefinitions of the purpose to present the experiment in class. Finally, we were able to understand some reasons that obstruct teachers' engagement with academic research proposals. [ABSTRACT FROM AUTHOR]

The aim of this paper is to study the differences in homeownership of international migrants in Buenos Aires, from a demographic perspective still little applied to the subject in Latin America, which explores the intensity and calendar of the phenomenon in specific generations, groups and territories. Birth cohorts of different national groups were reconstructed based on variables such as age and place of birth from the Argentine population censuses from 1970 to 2010. As a main result, it was found that the older the population, the more widespread is homeownership, but access to land has become more restrictive. This has affected recent generations in general, including the Argentine population, but especially migrants from neighboring countries of lower social sectors and in the most disputed territories of the city.

The paper sets out to analyze two urban development proposals from a comparative point of view. Based on a literature review of the Nueva Costa del Plata project and the data collected for my doctoral research on Puerto Madero, it traces both lines of continuity and emergent tendencies in the urban expansion of the Buenos Aires Metropolitan Area. From that basis, it proposes a conceptual revision of urban renewal through 'waterfront revitalization', and goes on to put in context the relationship of the city of Buenos Aires and its metropolitan area with the Río de la Plata. Finally, it deploys each of the contrasting proposals, in order to arrive at a comparative analysis that allows reflection on urban renovations of the waterfront of the Buenos Aires Metropolitan Area.

The purpose of this article is to describe and analyze the reconversion experiences of four social organizations to sustain the social bond and collective care in popular neighborhoods of the Metropolitan Area of Buenos Aires (AMBA), Argentina, during the Covid-19 pandemic. Based on qualitative research work with an ethnographic approach, conducted remotely between July and September 2020, we i) reconstructed the social context and characterized the activities of the socio-community organizations studied in AMBA, before and during the pandemic; ii) sketched images such as the collective "la olla" organization, which describe the community provision of care; and iii) showed how, in the context of restricted movement, the organizations had to deploy tactics to "contain," "accompany" and take care of themselves and others. In line with debates about an economy of care, which produces values surreptitiously appropriated by the rest of the economy, this paper focuses on those resulting from socio-community practices related to: food --"la olla" and "la fila"--, health, and socio-affective --"containment"--. This proposal is intended to contribute to the theoretical-political field of discussion, in which it is situated, on the paradox between the centrality of (socio-community) care, for the production of social welfare, and its insufficient recognition in economic, social, and political terms. Methodologically, the paper portrays the challenges --for social research-- of reading and interpreting practices when co-presenciality is technologically mediated. [ABSTRACT FROM AUTHOR]

With the outbreak and devastating spread of the SARS-CoV-2 pandemic, different forms of containment methods have been implemented across Latin America that have radically and rapidly transformed public health approaches. The purpose of this paper is to provide a preliminary delimitation of the problem of person-to-person accusations and complaints in proximity contexts under the confinement regime in the metropolitan area of Buenos Aires (AMBA). This paper examines three issues: 1) anthropological perspectives on judicialization; 2) the broad-ranging consequences and paradoxical effects that accusations, denunciations, and judicializations have been proven to cause for the well-being, health, and survival of affected individuals and social groups; and 3) the particularities that anthropological work assumes in highly normatized, sanctioned, and criminalized contexts. This article addresses heterogeneous materials: historical background, anthropological arguments, research results, media information, regulations, etc., to analyze the case of the AMBA. Specifically, the text focuses on the practices employed during the months of the initial period of confinement in AMBA, from March 20 to November 9, 2020. This analysis sheds light on the ways in which proximity accusations and allegations lead to the fragmentation of social fabrics, deepen inequalities, and accentuate uncertainty about social responses to possible infection and death. They also compromise and distort epidemiological, preventive, and care strategies. While legal actions of the same type have taken place for other ailments and epidemics, proximity accusations and allegations, in this case, are understood as enabled and legitimized strategies that express and translate deep transformations --at the micro-scale of isolation-- of the links between public health, legislation and security forces in social confinement regimes.

This work shows a technical-economic procedure to determine the adapted network in a low voltage (LV) residential electrical system with photovoltaic distributed generation (PVDG). A network is adapted when it is designed to minimize the total fixed and variable costs and optimize the equipment to adequately satisfy the demand (both the current demand and its expected growth). The study will consider that the decision to install PVDG is exogenous. The method is based on the concept of Hosting Capacity (HC). This paper analyzes four typical LV networks in the city of Buenos Aires, Argentina. A statistical power flow solves the networks. We take the following statistical variables: residential load, PV penetration, PV power, and location. We obtain the statistical HC for each network, and the HC is used to carry out the technical-economic study of the network. Finally, we establish the adapted network for each level of penetration. The results show that, without PVDG penetration, there are different network options with different costs per km2. When PVDG penetration increases, the networks with the lowest cost per km2 are discarded (due to their FCE), and only the networks with the highest cost per km2 survive. Once 70% penetration of PVDG has been exceeded, none of the studied networks is considered an option.. [ABSTRACT FROM AUTHOR]

At the intersection of social and digital inequality studies, this paper presents the results of a finished research about Information and Communication Technologies (ICT) appropriation among high school students from the City of Buenos Aires (CABA). From the results of an own survey and in-depth interviews, this article studies the digital capital accumulation in young people with the objective of analyzing the influence of social origin on the appropriation of ICT and the scope of social and digital reproduction. The results present a typology on youth appropriations, describing the expected destinations from the digital appropriation trajectories by social class and the dissident cases in which young people from different social classes have appropriated ICT in an “unexpected” way, when students of the same social class have trajectories with different destinations from the influence of digital scaffolding. The role of these scaffolds in the ICT appropriation processes constitutes the main finding of the research since they make possible the change of trajectories and social and digital mobility.

This paper investigates the spatiotemporal variations of the Surface Urban Heat Island (SUHI) computed as the difference of urban and rural land surface temperatures for the three major cities of Argentina: Buenos Aires, Rosario, and Cordoba. Satellite-based data of 1 km x 1 km resolution available through the Global Surface UHI Explorer were used to estimate mean and maximum values, trends and percentage of each urban area with positive/negative intensities of SUHI for the period 2003-2017. Results indicate that, on average the nocturnal urban surface temperature is higher than the rural one (positive SUHI) for the annual, winter and summer mean for the three cities. The greatest contrast corresponds to Buenos Aires, where the maximum SUHI magnitude is +2°C in summer and the minimum is +1,5°C in winter. Both Rosario and Cordoba exhibit a difference in magnitude between summer and winter of only 0,1°C. The percentage of the area of each city with nocturnal surface temperatures greater than the rural ones is on average, 93 % for Buenos Aires, 97% for Rosario and 89% for Cordoba. During daytime, in some cases the SUHI intensity is negative generating a cold island. This effect is observed in the three cities during the cold season and in Rosario and Cordoba for the annual mean. In Buenos Aires, that hosts more than 30 % of the total population of the country, there is a significant positive trend in the daytime mean and maximum SUHI intensity. The comparison between the Buenos Aires' SUHI and canopy UHI (derived from standard air temperature measurements) shows positive intensities during night-time in both cases, although the mean annual and summer SUHI are warmer than the UHI in +0,3°C and +0,6°C, respectively. Additionally, there is a trend towards warmer daytime intensities of both types of heat islands. [ABSTRACT FROM AUTHOR]

The following paper addresses the study of those knapping processes occurred during the middle Holocene in Laguna de los Pampas (Central Pampean Dunefields, Buenos Aires), carried out through tecnomorphologic and technological (chaînes opératoires) studies of the lithic artifacts recovered in the surface of the Sector 2. The results obtained points to the employ of a wide diversity of raw materials, which sources are located at least 170 km away from the site, and among which stands the orthoquartzites and cherts from Tandilia. For these two rocks, as well as for the silicified dolomite, a direct acquisition is proposed. The production of blanks was mainly made by the unipolar and centripetal débitage. The presence of dull edges, reactivation flakes and exhausted cores, as well as the employment of the bipolar reduction, suggest an optimization in the exploitation of rocks. [ABSTRACT FROM AUTHOR]

The aim of this paper is to discuss conceptualizations regarding drainage basin management and spatial planning, later to inquire how these viewpoints influence the instruments and institutions that currently guide the development of such areas in the Metropolitan Region of Buenos Aires (RMBA, Región Metropolitana de Buenos Aires). In terms of methodology, we collated and analyzed the most representative instruments and institutions which influence the RMBA, including specific bibliography, technical reports and official websites. The results show that the traditional conceptualization of both spatial planning and drainage basin management still predominate. In addition, the diverse instruments consulted do not seem to properly attend to the environmental and spatial complexity of the RMBA, given the latter's multiple jurisdictions and the high degree of normative dispersion.

This paper introduces part of the results of an investigation that aimed to analyze, from a socio-pedagogical perspective, the conflict and coexistence strategies between students and teachers of secondary schools in Buenos Aires City. From a qualitative methodology, through classroom observations and interviews with students and teachers from two secondary schools, we analyzed the meanings and practices they construct around different uses of cell phones in the classroom. We found meanings and practices linked to students' boredom or lack of interest, negotiations between teachers and students, and manners of regulating their use by the latter. Although cell phones generate conflictive situations and constitute a challenge to manage coexistence in school classes, we conclude that their presence in classrooms is not necessarily the cause but rather the expression of tensions inherent to the relational dynamics of contemporary secondary schools.
