This paper explores the emergence of short-term rentals (STR) in Buenos Aires, a phenomenon that has been little explored in Latin America. We argue that STR are a flexible modality of real estate rent which accelerates the turnover of capital and mobilizes it globally through new transnational financial instruments, while, at the local level, it reinforces the problems of access to housing. Using data gathered from Airbnb listings, interviews with key stakeholders, and government sources, three main dimensions of the phenomenon in Buenos Aires are analyzed: sociourban effects, the emergence of new actors in the urban rental chain, and the role of the state in the proliferation of short-term lets. Among the main findings, we observed that (a) this rental model reproduces and deepens socio-territorial inequalities; (b) the STR have given rise to new and renewed actors -national and transnational- in the chain of real estate rent extraction in Buenos Aires; and (c) the local state has contributed -by action and omission- to the deployment of STR, avoiding the negative effects on local residents' access to rental housing.

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]

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]

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.

This paper presents Tadesgná, a Toba woman “colocada” (placed) in Buenos Aires, and the reconstruction of her experience in shelters, a police station, jail, a hospital and a hospice in the years 1885- 1886. The analysis of this part of her biography allows us to understand some common denominators in the fate of indigenous women during that decade: the places where they were taken to, the multiple and successive transfers from one master to the following one, the language barrier difficulties and the several forms of violence they were subjected to. If we focus on the characterisation read in the sources with reference to her first menstruation period and her facial tattoo, it is clear that the discourses stemming from criminology, legal medicine, law, police and journalism were based on a racialisation and a configuration of gender that branded indigenous women with the utmost negativity, thus naturalising their ill-treatment [ABSTRACT FROM AUTHOR]

The article, firstly, deals with some definitions and classifications of medicines generated in the social science and biomedical fields. Then, the author proposes a systematization of medicines, incorporating new categories, as well as the notion of ethno-medical configuration, to explain healthcare in intercultural contexts. The categories introduced are biomedicine, traditional medicine, alternative medicine, religious therapy or medicine, and lay-treatment. Finally, as an illustrative example, the paper focuses on the ethno-medical configuration of the Metropolitan Area of Buenos Aires, Argentina. The goal of this systematization is proposing categories that consider the understandings and behaviors of social actors. [ABSTRACT FROM AUTHOR]

The paper analyzes the construction of coherence, specifically causal coherence, in children's narratives of personal experience. The study focused on the examination of causal relations and other types of connections established between the narrated events, as well as the presence of fragments of unrelated events. The corpus consists of 66 narratives produced by Argentinian Spanish-speaking children aged 3, 4 and 5 years. Narratives were obtained in individual interviews carried out in the kindergartens where children attended, located in urban-marginalized neighborhoods of Buenos Aires (Argentina). For the analysis of the narratives, we used a heuristic approach of an adapted version of Trabasso et al. Causal Network Narrative Model. The analysis combined qualitative and quantitative procedures. The results showed that children managed to connect the narrated events causally, temporally, and thematically. During this period, there predominated causal connections related to the physical (vs. mental) domain. The diversity of causal relations established within the same narrative increased with age. The narratives also contained unrelated events: breaks in the causal chain, dead-end events. The latter mostly referred to different components of narrative information (action, orientation, evaluation) that contribute to the coherence of the narrative in other non-causal dimensions. The results acquire special relevance for the study of children's narrative production, considering the role of narrative in cognition, communication, socialization, and the transmission of culture.

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.

The purpose of this paper is to analyze the transformations in the frameworks of reflection and action that promoted territorial documentation policies, developed in coordination between the National Direction of Migration and the provincial and municipal governments in the southern area of Greater Buenos Aires, Argentina. Based on an ethnographic approach to the activities of a local office, the Dirección de Entidades y Colectividades de La Plata, and interviews with its main managers, we focus on the interrelation between documentation policies and the visibility (and production) of the electoral potential of foreigners that crystallized during the implementation of these programs. Unlike the literature that focuses on the analysis of the intentions (explicit or implicit) of the laws and projects, and on the difficulties encountered in achieving the purposes stated in them, the originality of the article is given by its monitoring of positions, relationships, languages, and objects that were produced (to some extent unexpectedly) during their implementation. This strategy reveals that the documentary programs and the officials who carry them out have gradually become part of the networks of the so-called territorial policy, in which the relevance assigned to foreigners has increased. The fundamental shift in this dynamic is the progressive recognition of its electoral potential and the conceptualization of the migration issue as an area of strategic dispute for local and provincial political life. Thus, the main conclusion is that throughout the implementation of these programs, migration policy became politicized; that is, it acquired a "political" status in the consideration of different relevant actors. This recognition lasted even after document operations were discontinued in 2016 and was part of their reinstatement in 2019. [ABSTRACT FROM AUTHOR]

This paper illustrates the insights that can be gained from using a multidimensional poverty measurement method based on the capability approach to analyse the scale, characteristics, and spatial distribution of poverty in segregated cities. We assess the poverty gaps between formal and informal neighbourhoods and across districts, compare the results with income-based poverty estimates, and analyse the dimensional composition of poverty and disparities across population subgroups. The results show a weaker correlation between multidimensional and income-based measures and less overlap in terms of who is identified as poor in informal settlements than in the rest of the city. After adjusting for underrepresentation of the slum population in the household survey, informal settlements account for 10% of the city's population but nearly half of the multidimensionally poor. The results highlight the need to design poverty reduction policies that target informal neighbourhoods. [ABSTRACT FROM AUTHOR]

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 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]

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 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.

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.

In this paper, we discuss the meanings assumed by citizen science for the regulation of therapeutic and medical uses of cannabis in Argentina, considering the mobilization of experiences in three municipalities of the province of Buenos Aires. Through conceptual tools of the STS field and techniques such as documentary analysis of resolutions and ordinances, participant observation, and in-depth interviews, we address the role of proximity experienced locally in the development of municipal regulation initiatives; the combination of different types of expertise (technical, scientific, medical, legal, experiential); and the processes of resignification and change of social identifications. The research shows that local regulations emerge from a heterogeneous social base that, in the form of citizen science, produces, uses, and transmits diverse expertise around the therapeutic uses of the plant and its derivatives. It also reveals that the construction processes of local government policies promote new social perceptions of certain groups (supportive growers, physicians, child users) that influence the way that therapeutic cannabis is settled as a public problem.

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.

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]

Garretón's "Una teoría cibernética de la ciudad y su sistema" (A cybernetic theory of the city and its system) was published in 1975 by Nueva Visión publishing house in Buenos Aires, a moment when the seminal criticisms against the modernist urban theory of the sixties led by Team 10 were becoming concrete proposals for updating and eventually overcoming its shortcomings. Yet, despite remaining unpublished in English and hence relatively unknown worldwide, few publications in the field compare in scope to Garreton's cybernetic theory. The reason is straightforward: like Shannon's mathematical theory, this work amounts to a general theory of the city. Thoroughly informed by system thinking, whose trademark rule of thumb was described by Luhmann as "drawing distinctions" to guarantee the autopoiesis of a determined system, Garretón's chief objective was to draw distinctions that would guarantee the autopoiesis of the urban system. In doing so, he discovered three fundamental urban laws, namely: the law of urban communication, the law of urban attraction, and the law of urban circulation. This, in turn, allowed him to clearly distinguish a universe that had thus far remained undetected by urbanists and that he called the non-city Universe: the human-made universe that nevertheless does not belong in the urban universe. This paper argues that this allowed him to rediscover and update the ancient and lost art of city-making: not an art of making buildings, roads, and infrastructure in general but rather, the art of building, knitting, fostering, and sustaining communities and whole societies by means of or with the aid of buildings.

Towards the end of the 1960s—a period of intense creative, technological and political changes—the Argentinian art critic and entrepreneur Jorge Glusberg founded the CAyC (Center for Art and Communication) in Buenos Aires. CAyC was an interdisciplinary experimental project that explored the relationship between art, technology and society. It sought to articulate a network of discussions and productions by a new style of Latin American artist, deeply influenced by science, technology and society. Glusberg defined such practice as Systems Art, which appeared in three ways, namely as a system of collective representation; a system of meaning that defied formal categories; and a system of relationships and processes for social inquiry. In doing so, the artist became a researcher who reflected on their social context and the latter's processes of production. This paper will discuss CAyC's pioneering work and its global influence through three main initiatives: its exhibitions Art and Cybernetics, Systems Art in Latin America and the International Open Encounters on Video. These events were driven by the revolutionary artistic and experimental promotion of the distinctive ways in which Latin American artists were using technology to respond to local issues at a time when computer systems and cybernetic models for management and organizational practices were being introduced across the region.

Under the background of "the Belt and Road" and "the economic corridor of China, Mongolia and Russia" initiatives, it has great value to study the temporal and spatial evolution characteristics of the coordinated development between the urbanization and ecological environment in eastern Russia (the Siberian Federal District and the Far East Federal District). In this paper, we studied the urbanization development level, eco-environment development level, and their coupling coordinated development degree during 2005–2018 in the eastern Russia from the perspectives of the 3D global trend and 2D plane analysis. First, combining with the Population-Economic-Sociology and Pressure-State-Response models, the urbanization development level and eco-environment development level were calculated by the comprehensive weighting method of entropy weight and variation coefficient for eastern Russia. Second, the coupling coordinated development degree of the urbanization development level and eco-environment development level was measured by the coupling coordination model for eastern Russia. Finally, the spatial differentiation of the urbanization development level, the eco-environment development level and their coupling coordinated development degree was performed respectively by the 3D global trend and 2D plane analysis using ArcGIS. The results are as following. First, the comprehensive urbanization development level of eastern Russia has increased from 2005 to 2018, and the economic urbanization is the main factor that affects the urbanization development in eastern Russia. The comprehensive eco-environment development level of eastern Russia has decreased from 2005 to 2018, and the eco-environment pressure is the main factor that affects the eco-environment development in eastern Russia. The coupling coordination degree of the urbanization development and eco-environment development has increased from 2005 to 2018. However, it is still in the uncoordinated stage. Second, from 2005 to 2018, the urbanization development level of the Siberian Federal District is higher than that of the Far East Federal District. The eco-environment development level of the Siberian Federal District is balanced to that of the Far East Federal District. The coupling coordination degree of the Siberian Federal District is higher than that of the Far East Federal District. Among the Siberian and Far East Federal Districts, most of the federal subjects belong to the uncoordinated stage of the urbanization development and the eco-environment development. Third, the urbanization development level, the eco-environment development level, and their coupling coordinated development level are all spatially imbalanced in the eastern Russia, which show the "High West, Low East" and "High Center, Low North and Low South" spatial pattern from the perspectives of the 3D global trend and 2D plane analysis. The areas with high levels are concentrated in the Novosibirsk Region, Altay Territory, Kemerovo Region, Krasnoyarsk Territory, and Irkutsk Region. The areas with low ones are mostly in the Republic of Altay and Chukotka Autonomous Area. Finally, we suggest policies and strategies that can boost the growth and development of the urbanization and the eco-environment in the Sino-Russian border areas. [ABSTRACT FROM AUTHOR]

The paper has a double purpose. It contains a short excerpt from a Polish translation of the latest known adaptation of Bovo-Bukh authored by Moshe Knapheys and published by YIVO in Buenos Aires in 1962. It also contains a basic exegesis of the chivalry poem, starting with its earliest incunables in a vernacular with strong Venetian traits, printed in the 1480s, through its first adaptation in Yiddish-Taytsh by Elia Levita, originally written in Padua in 1507, but published in Isny only in 1541. The Polish translation from modern Yiddish according to the 1962 version also contains a critical apparatus in which the early Venetian text (a 1487 incunable), and Levita's Yiddish-Taytsh adaptation of the latter, according to both the 1507 manuscript and the 1541 print, are taken into consideration for comparison.

This article analyzes the tensions between work and intimacy for gay men in Argentina. Through interviews with young gay men in Buenos Aires, three labor of love tasks are identified that intertwine with the workplace. These tasks include negotiating identity when coming out at work, fulfilling desires and the role of eroticism in accessing work, and stabilizing relationships and how employment or unemployment becomes an obstacle. It is concluded that it is necessary to analyze the intersections between love and work in terms of both form and content. [Extracted from the article]

Calliphora vicina Robineau-Desvoidy is a primary colonizing species of decomposing bodies, being predominant in the cold seasons in Buenos Aires province, Argentina. The minimum post-mortem interval (PMImin) was estimated using growth and larval length parameters as the accurate entomological evidence of the elapsed time since death. Specimens were reared at 12, 14, 16, and 18 °C, and the larval and pupal growth rates were determined. Differences in the developmental times were registered (43.2 days at 12 °C, 34.3 days at 14 °C, 29.1 days at 16 °C, and 24.3 days at 18 °C), with the lifespan shortened at higher temperatures, without changing the larval length range (-1.5--18.0 mm). Temperature also influenced the survival and size of emerged adults; the highest percentage of survival registered at 14 (29.73%) and 16 °C (38.65%), and more mortality in extreme temperatures (19.00% at 12 °C and 12.61% at 18 °C). Adults reared at 12 °C were the largest of all, females were longer than males, and body size showed an inverse relationship with survival. These results allowed the PMI estimation based on data from local populations instead of consulting papers based on other regions. [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.

Under the background of "the Belt and Road" and "the economic corridor of China, Mongolia and Russia" initiatives, it is of great significance to study the temporal and spatial economic pattern in the Russian Federation. Based on the economic development difference index, regional economic grade index, global trend analysis tool and spatial autocorrelation model, this paper analyzes the temporal and spatial pattern evolution characteristics of Russian economic differences from 2002 to 2020. The results are as following. First, although the economic imbalance among various federal subjects has been decreasing, the economic polarization has been still severe between the prosperous developed regions and the stagnant backward regions during 2002–2020. Russia's economy shows a trend of changing from significant positive correlation in strong agglomeration space to positive correlation in weak agglomeration space, and then to random distribution. Second, there has been great differences of the economic development among various federal subjects. The economic grade of the Russian federal subjects presents a significant spatial differentiation pattern. The Russian Federation's economic resources are concentrated in the first-class federal subject (Moscow City), second-class federal subjects (Tumen Region, Moscow Region and Saint-Petersburg city) and a few third-class federal subjects (Yamalo-Nenetsky Autonomous Area, Khanty-Mansiysky Autonomous Area, Republic of Tatarstan, Krasnodar Territory, Sverdlovsk Region, etc). Third, the Russian Federation's economy presents "High Core, Low Periphery", "High West, Low East" and "High south, Low north" spatial differentiation pattern. The economic hot regions coincide with the high-class economic regions, which are mainly distributed in the contiguous areas of Ural Federal District and Volga Federal District, as well as the Moscow City, Moscow Region, Saint-Petersburg city, Krasnodar Territory and Rostov Region. The economic cold regions coincide with the low-class economic regions, which are mainly located in the Far East Federal District, the east of Siberian Federal District, the north of North West Federal District and the south of North-Caucasian Federal District. Finally, we suggest the recommendation for policy makers in Russia. And we propose the future research ideas. [ABSTRACT FROM AUTHOR]

This paper identifies and characterizes a corporate network based on Argentinian-Spanish business (Catalan mainly) that was built around a dozen companies all located in Buenos Aires, in the first half of 20th century. Studying the board of directors of the company Providencia Compañía Argentina de Seguros, it finds meeting points in which different groups are involved and it analyzes what corporate strategies they applied. It also determines whether any political compromise was acquired by the members of the network, both in Spain and Argentina. [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]

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 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.

In this paper I recover an ethnographic research developed with groups and organizations of artists from Buenos Aires and focus on a particular event: the intention of the local government to regulate the artistic activity in the public sphere that took place during 2018 and the mobilization in rejection that it activated, demanding the right to street artwork under the slogan "street art is not a crime". I analyze how this process implied resignifications in the ways of thinking the social/political role of art and artists as well as the role of the State in relation to art and culture. These transformations that had been unfolding since previous years activated politicization processes of various actors in the cultural field in relation to demands for cultural rights, policies and legislation. I argue that the resistance that was unleashed in the face of the attempt to regularize/penalize street art must be analyzed in connection with this background of political-collective organization in the cultural field as well as with a resignification of the ways of conceptualizing the political potential of artistic practices, the independence/self-management and cultural rights.

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.
