Abstract (Introduction): Within the framework of the present capitalist system, human beings have become an important polluting agent. Current production and consumption processes do not consider the existence of finite natural resources and a planet incapable of treating the waste that the prevailing way of life generates. Given these circumstances, the study of non-linear models is of interest, which make a more rational use of the waste that the productive activity generates, favoring recycling mechanisms. The phenomenon of recycling becomes particularly relevant in the case of electrical and electronic devices, whose ability to be degraded and metabolized by planet Earth is extremely difficult. (Objective): Evaluate the feasibility of installing and starting a recycling plant for electrical and electronics items in the town of Bahía Blanca (Argentina), during 2021. (Methodology): The conventional method for evaluating investment projects was used, considering technical, legal and economic aspects. (Results): The project is not acceptable according to the profitability intended by the investor. The possibility of financing was also included, which made the project even less profitable, and the sensitivity of the results was measured, finding that the price should be 1.48 % higher than that used in the analysis. (Conclusions): Other alternatives must be explored to make this proposal profitable from an economic and financial point of view.

Resumen (Introducción): En el marco del sistema capitalista vigente, el ser humano se ha transformado en un agente significativo de contaminación. Las dinámicas productivas y de consumo actuales no contemplan la existencia de recursos naturales finitos y de un planeta incapaz de procesar los desperdicios que el modo de vida habitual genera. Dadas estas circunstancias, cobra interés el estudio de modelos no lineales, que hagan un uso más racional de los residuos derivados de la actividad productiva, los cuales favorezcan mecanismos de reciclaje. El fenómeno del reciclaje se vuelve, en particular, relevante para el caso de los artefactos eléctricos y electrónicos; la capacidad del planeta Tierra para degradarlos y metabolizarlos resulta sumamente difícil. (Objetivo): Evaluar la factibilidad de la instalación y puesta en marcha de una planta recicladora de artículos eléctricos y electrónicos en la localidad de Bahía Blanca (Argentina), durante el 2021. (Metodología): Se utilizó la metodología convencional de evaluación de proyectos de inversión, considerando aspectos técnicos, legales y económicos. (Resultados): El proyecto no es aceptable según la rentabilidad pretendida por el inversor. También se incluyó la posibilidad de un financiamiento, lo que hizo que el plan fuera menos rentable aún, y se midió la sensibilidad de los resultados: se halló que el precio debiera ser 1.48 % superior al utilizado en el análisis. (Conclusiones): Se deben explorar otras alternativas para lograr que el proyecto sea rentable desde el punto de vista económico-financiero.

Alfred Schaeffer (1879-1957) was a German chemist who arrived in Minas Gerais in 1911 hired by the state government to organize the state health service in its newly established capital. He directed the Laboratory of Chemical Analysis of the State, and his analytical methods in dairy and mineral waters became a reference in Brazil. He also became professor of Chemistry at the new Faculty of Medicine of Belo Horizonte and founded the Chemistry Institute of the Engineering School in that city, influencing several students who became important names in Brazilian science. In addition, he was responsible for the assembly and technical coordination of pioneering industries in the dairy and wood distillation sector in the city of Santos Dumont. Later he assumed the post of technical director of Merck, also in Minas Gerais. Moving to Rio de Janeiro, he assumed a chair at the Technical School, working in teaching and research, and remained active even after retiring, publishing in important scientific journals. 18791957 1879 1957 (1879-1957 191 capital State Brazil science addition Dumont Merck Janeiro research retiring journals 1879195 187 195 (1879-195 19 187919 18 (1879-19 1 18791 (1879-1 (1879- (1879 (187 (18 (1 (

Resumo Interpreto as relações entre o abandono e a rememoração a partir das possibilidades de ressignificação da Fábrica de Cimento Portland de Perus. Abandonada desde a década de 1970, as instalações da falida Companhia Brasileira de Cimento Portland são, hoje, objeto de ações culturais de movimentos sociais de Perus, distrito da zona noroeste da Cidade de São Paulo. Estes procuram retomar memórias pessoais e coletivas da chamada Greve dos Queixadas, que tomou a Fábrica durante sete anos e legou ao território uma identidade de luta por direitos e cidadania.

Abstract In this paper, I interpret the relationship between abandonment and remembrance based on possibilities for re-signifying the Perus Portland Cement Factory. Abandoned since the 1970s, the facilities of the bankrupt Companhia Brasileira de Cimento Portland are today the object of cultural actions organized by social movements in Perus, a district in the northwest of the city of São Paulo. The movements aim to recapture personal and collective memories of the so-called Queixadas Strike, which took over the factory for seven years and left to the territory an identity of struggle for rights and citizenship. Based on the analysis of interviews, I discuss the counter-narrative created by one of these collectives, the Comunidade Cultural Quilombaque, to oppose oblivion and announce the potential of its territory. paper resignifying re signifying Factory 1970s s Paulo socalled so called Strike citizenship interviews counternarrative counter narrative collectives Quilombaque

Abstract This paper aims to understand and characterize the emergence of tertiary spaces in the post-industrial city, focusing on the spatial and production transformations they promote. We understand tertiary spaces as novel urban forms targeted at the spatial and production repurposing of consolidated areas that stimulate the growth of the tertiary sector, commercial vitality, and urban dynamism. The study focuses on the Metropolitan Region of Buenos Aires. The methodological strategy is qualitative, and data were produced through a morpho-typological survey and interviews with municipal authorities and entrepreneurs in the sector. The results show the role played by those forms in the urban and production repurposing of previously industrial areas. postindustrial post city promote sector vitality dynamism Aires qualitative morphotypological morpho typological

ABSTRACT: Based on the data of China’s overseas arable land investment in 47 countries along the “Belt and Road”, the Tobit model is used to analyze the effects of cultural distance and friendship cities on the production rates of contracted arable land in China’s overseas arable land investment. This study provided theoretical basis and empirical support for promoting China’s agricultural “going abroad” and improving the production rates of contracted arable land in China’s overseas arable land investment. The results show that differences in cultural distance, power distance and the degree of uncertainty avoidance have significant positive effects on the production rates of contracted arable land in China’s overseas arable land investment, and differences in individualism have a significant negative effect on the production rates. Friendship city has a positive but insignificant effect on the production rates, meanwhile, it also weaken the positive impact of cultural distance on production rates of contracted arable land in China’s overseas arable land investment. The proportion of joint ventures with host country, the economic level and institutional environment of the host country will all have an impact on the production rates. Finally, recommendations are proposed to promote the production rates of contracted arable land, such as focusing on the positive role of cultural distance, establishing friendship cities, and investing host countries with high potential precisely.

RESUMO: Com base nos dados do investimento da China em terras aráveis no exterior em 47 países ao longo do “Cinturão e Rota”, o modelo Tobit é utilizado para analisar os efeitos da distância cultural e das cidades amigas nas taxas de produção de terras aráveis contratadas no investimento da China em terras aráveis no exterior. Os resultados mostram que as diferenças na distância cultural, na distância de poder e no grau de prevenção de incertezas têm efeitos positivos significativos sobre as taxas de produção de terras aráveis contratadas no investimento em terras aráveis no exterior da China, e as diferenças no individualismo têm um efeito negativo significativo sobre as taxas de produção. As cidades amigas têm um efeito positivo, mas insignificante, sobre as taxas de produção, enquanto estas podem enfraquecer o impacto positivo da distância cultural sobre as taxas de produção de terras aráveis contratadas no investimento em terras aráveis no exterior da China. A proporção de investimento cooperativo entre a China e o país anfitrião, o nível econômico e o ambiente institucional do país anfitrião terão um impacto sobre as taxas de produção. Por fim, são propostas recomendações para promover as taxas de produção das terras aráveis contratadas, tais como a concentração no papel positivo da distância cultural, a criação de cidades da amizade e o investimento em países de acolhimento com elevado potencial.

This paper elucidates the inseparable connection between the pursuit of a more ecologically sustainable society and the quest for socioeconomic justice. It also demonstrates why Unconditional Basic Income (UBI) is an effective policy to act on both fronts. First, the corresponding theory on environmental and socioeconomic oppression sheds light on the argument that both types of domination stem from the same historical process and are inherently interconnected. Addressing one without considering the other is essentially flawed; they are both features and consequences of present society. Acknowledging the historical debt owed to vulnerable economic classes and developing countries is imperative. Green republicanism could potentially establish a theoretical foundation for social-ecological thinking. Defining freedom as non-domination and applying this concept to nature are essential prerequisites for overcoming socioeconomic and environmental oppression. UBI is presented and discussed theoretically as a strong solution to address these two challenges. It serves not only as a means to facilitate the transition to a post-productivist society, transforming labor relations, but also as a catalyst for the development of circular economies and more sustainable occupations. Additionally, the basic income policy implemented in the city of Maricá, Brazil, is cited as empirical evidence showcasing the environmental and socioeconomic values of UBI. justice (UBI fronts First interconnected flawed imperative socialecological social ecological thinking nondomination non challenges postproductivist post productivist relations occupations Additionally Maricá Brazil

A series of novel thieno[2,3-d]pyrimidine derivatives were designed, synthesized and evaluated for their biological ability. 2-Amino-4,7-dihydro-5H-thieno[2,3-d]pyrano-3-cyanonitrile was synthesized by Gewald reaction using pyranone as substrate, malonitrile and sulfur powder as raw materials and triethylamine as base at room temperature. Subsequent amination with N,N-dimethylformamide dimethyl acetal (DMF-DMA) gave N'-(3-cyano-4,7-dihydro-5H-thieno[2,3-c]pyran-2-yl)-N,N-dimethylmethanimidamide. In this article, the 23 thieno[2,3-d] pyrimidines were obtained by Dimroth rearrangement condensation with different anilines, 16 of them being new compounds. Meanwhile, all compounds were assessed for breast cancer MDA-MB-231 cell line bioactivity with paclitaxel (PTX) as the positive control, and all compounds in the series showed inhibitory effects on breast cancer cell MDA-MB-231. The IC50 of compound l against MDA-MB-231 is 27.6 μM, which is similar to that of PTX with an IC50 of 29.3 μM. This means that compound l exhibits comparable inhibitory activity to PTX in MDA-MB-231 cells and may be considered as a potential anti-MDA-MB-231 inhibitor. thieno2,3dpyrimidine thieno23dpyrimidine thienodpyrimidine thieno 2,3 d pyrimidine 2 3 designed ability 2Amino4,7dihydro5Hthieno2,3dpyrano3cyanonitrile 2Amino47dihydro5Hthieno23dpyrano3cyanonitrile AminodihydroHthienodpyranocyanonitrile Amino 4,7 dihydro 5H pyrano cyanonitrile 4 7 H substrate temperature N,Ndimethylformamide NNdimethylformamide N,N dimethylformamide N DMFDMA DMF DMA (DMF-DMA N3cyano4,7dihydro5Hthieno2,3cpyran2ylN,Ndimethylmethanimidamide.

What motivates voters to support candidates with backgrounds in public security for Brazil’s National Congress, the so-called Law & Order (L&O) politicians? The 2018 elections witnessed a surge in parliamentarians from police and military backgrounds and the election of a president closely aligned with this agenda. We explore whether this trend correlates with municipal-level violence indicators and the presence of municipal capacity in the security sector, employing various regression models that account for socioeconomic, demographic, political, and geographic factors. Our findings from the additive model reveal a negative association between the level of violence and votes for L&O candidates. This suggests a potential disconnection between fear, victimization, and support for repressive policies, while also indicating that local capacity in the security sector tend to enhance L&O candidates’ performance. However, our model incorporating the interaction between both variables uncovers that violence exacerbates the negative impact on L&O voting when the city has capacity in the security sector. This may reflect a municipal-level preference for preventive measures, particularly in more violent areas, which contrasts with the generally repressive stance of L&O candidates.

Resumo A expansão desordenada das cidades é um desafio global que afeta o desenvolvimento urbano. Neste estudo, é analisado o crescimento urbano em uma cidade média durante cinco décadas, com enfoque na forma urbana e aplicação de mais de 20 métricas espaciais associadas à mensuração da geometria da expansão físico-territorial no ambiente construído. Os padrões de crescimento são analisados à luz do fenômeno espraiamento urbano e sob a perspectiva da teoria de Difusão-Coalescência. São discutidas as limitações inerentes às métricas existentes, assim como elencadas alternativas que as superam por mensuração das propriedades de Compacidade, Fragmentação, Complexidade e Dispersão concomitantemente. Os resultados demonstraram a ocorrência de fases distintas no crescimento urbano ao longo das décadas: Difusão de uma forma inicialmente compacta em partes menores nas periferias; e Transição para crescimento com agrupamento dessas partes, elevando a compacidade. Essa oscilação sugere aderência à teoria da Difusão-Coalescência, com ocorrência de espraiamento urbano (entre 1966 e 1976) seguida de aumento da compacidade nas décadas subsequentes (1976-2006). Após 2006 os resultados são ambíguos, possivelmente associados a fatores intervenientes de planejamento. A discussão dos resultados destaca a relevância da quantificação do crescimento urbano por meio de métricas, e traz conceitos importantes atualmente limitados à literatura internacional. estudo 2 físicoterritorial físico territorial construído DifusãoCoalescência.

Abstract The disorderly expansion of cities is a global challenge that impacts urban development. In this paper, we analyse the urban growth in a medium-sized city over five decades, focusing on urban form and employing more than 20 spatial metrics associated with the geometry of physical-territorial expansion in the built environment. We examine the growth patterns in the context of the urban sprawl phenomenon and the Diffusion-Coalescence theory perspective. We discuss the inherent limitations of existing metrics and raise alternatives that simultaneously address the properties of Compactness, Fragmentation, Complexity, and Dispersion. The results reveal distinct phases in urban growth over the decades, from diffusion of an initially compact form into smaller parts on the periphery; to a transition towards more compact growth. This oscillation suggests adherence to the Diffusion-Coalescence theory, with urban sprawl occurring between 1966 and 1976, followed by increased compactness in subsequent decades (1976-2006). After 2006, the results became ambiguous, possibly due to intervening planning factors. The discussion of the findings underscores the importance of quantifying urban growth using metrics and introduces concepts that have been hitherto limited to international literature. development paper mediumsized medium sized 2 physicalterritorial physical territorial environment DiffusionCoalescence Diffusion Coalescence perspective Compactness Fragmentation Complexity Dispersion periphery 196 1976 19762006. 19762006 2006 .

Abstract This work aims to model per capita water consumption in schools in the city of Joinville-SC. As the school environment is largely responsible for the transmission of knowledge, including information on water conservation, 26 public schools were selected for this research. A survey was carried out on the use of water, through visits and a questionnaire to the management team of each school. The data collected allowed the characterization of schools and a preliminary diagnosis of water use. A descriptive analysis of per capita water consumption was performed, with values ranging from 5.15 to 18.59 liters/student/day. Correlation analysis, multiple linear regression, Bayesian linear regression and geographically weighted regression were used. The results of the correlation analysis reveal that the higher the average income in the neighborhood where the school is located and the area per student ratio, the higher the per capita water consumption. On the other hand, the number of students has a negative correlation with per capita consumption. In the statistical modeling, the independent variable area per student ratio was significant.

Resumo Este artigo tem como objetivo a modelagem estatística do consumo de água per capita em escolas da cidade de Joinville, SC. Levando em consideração que o ambiente escolar é grande responsável pela transmissão de conhecimentos, inclusive acerca da conservação da água, foram selecionadas para objetos de estudo desta pesquisa 26 escolas públicas da rede estadual de ensino fundamental e médio. Efetivou-se um levantamento sobre a utilização da água, por meio de visitas e questionário à direção de cada escola. Os dados coletados permitiram a caracterização das escolas e um diagnóstico preliminar do uso da água, com valores de indicador de consumo variando entre 5,15 e 18,59 litros/aluno/dia. Foi feita a análise de correlação entre as variáveis e posterior modelagem do consumo de água nas escolas, usando regressão linear múltipla, regressão linear Bayesiana e regressão geograficamente ponderada. Os resultados da análise de correlação revelam que quanto maior a renda média no bairro em que a escola está localizada e a razão área por aluno, maior o indicador de consumo. Por outro lado, o número de alunos apresenta correlação negativa com o indicador de consumo. Na modelagem estatística, a variável independente razão área por aluno apresentou-se significativa.

Abstract Choosing a university degree in Mexico is an important decision, especially if, upon completing high school, you wish to enter a Higher Education Institution. Indeed, private universities have assumed the responsibility of being competitive by offering professional training that allows effective job placement. That is why the present study was carried out in the City of Puebla Mexico, since it is one of the entities with the largest number of universities. A qualitative research was carried out, supported by an exploratory methodology, content analysis and digital positioning, including a search in different academic databases such as Scopus, Ebsco, Web of Science, among others. Among the results, it stands out that there are activities that favor brand positioning in private universities in Puebla through educational marketing; likewise, it was found that the actions that the different private higher education institutions have are numerous and seek to capture the attention of applicants and, finally, it was determined which of these actions represented favorable results in terms of improving perception and achieve improvement in their enrollment in an institution.

Abstract Introduction: The problem of energy security has already been addressed from a multidimensional approach, but always associated with a geopolitical, national security or sovereignty issue. Internal security during neoliberalism represents a process of inflation of the penal system. Thus, energy security, even from a multidimensional approach, is blurred if an approach that criminalizes those who self-manage access to the rights to adequate life and housing, to energy and to the city predominates. Objective: The main objective of this article is to propose a new way of understanding the problem of energy security, taking it from a watertight concept to a pendulum between "security/insecurity" that serves to weigh the degree of enjoyment of these rights. Methodology: For this purpose, housing fires between 2018 and 2023 in a city of 640 thousand inhabitants (Salta, Argentina) were collected, analyzed and systematized, and this information was crossed with data from the National Registry of Popular Neighborhoods and the Municipality of Salta. Conclusions: This allowed concluding that reappropriating "energy security" as a shield to guarantee access to rights is a fertile ground not only for academic purposes, but also for legal, social and political ones.

Resumo Introdução: O problema da segurança energética já foi tratado a partir de uma abordagem multidimensional, mas sempre associado a uma questão geopolítica, de segurança nacional ou de soberania. A segurança interna sob o neoliberalismo representa um processo de inflação do sistema penal. Assim, a segurança energética, mesmo a partir de uma abordagem multidimensional, fica embaçada se predominar uma abordagem que criminaliza aqueles que autogerenciam o acesso aos direitos à vida e à moradia adequadas, à energia e à cidade. Objetivo: O principal objetivo deste artigo é propor uma nova forma de entender o problema da segurança energética, levando-o de um conceito estanque para um pêndulo entre "segurança/insegurança" que serve para ponderar o grau de gozo desses direitos. Metodologia: para isso, foram coletados, analisados e sistematizados os incêndios em moradias entre 2018 e 2023 em uma cidade de 640.000 habitantes (Salta, Argentina), e essas informações foram cruzadas com dados do Registro Nacional de Bairros Populares e do Município de Salta. Conclusões: Isso levou à conclusão de que a reapropriação da "segurança energética" como escudo para garantir o acesso a direitos é um terreno fértil não apenas para fins acadêmicos, mas também para fins jurídicos, sociais e políticos.

Resumen Introducción: el problema de la seguridad energética ha sido ya abordado desde un enfoque multidimensional, pero siempre asociado a una cuestión geopolítica, de seguridad nacional o de soberanía. La seguridad interna durante el neoliberalismo representa un proceso de inflación del sistema penal. Así, la seguridad energética, incluso desde un enfoque multidimensional, se desdibuja si predomina un enfoque que criminalice a quienes se autogestionan el acceso a los derechos a la vida y vivienda adecuadas, a la energía y a la ciudad. Objetivo: el objetivo principal de este artículo es proponer una nueva forma de comprender el problema de la seguridad energética, llevándola de un concepto estanco a un péndulo entre “seguridad/inseguridad” que sirva para ponderar el grado de goce de esos derechos. Metodología: para ello, se recopilaron, analizaron y sistematizaron los incendios de viviendas entre 2018 y 2023 en una ciudad de 640 mil habitantes (Salta, Argentina) y se cruzó esa información con datos del Registro Nacional de Barrios Populares y de la Municipalidad de Salta. Conclusiones: ello permitió concluir que reapropiarse de la “seguridad energética” como escudo para garantizar el acceso a derechos es un terreno fértil no sólo a los fines académicos, sino también jurídicos, sociales y políticos.

Abstract Introduction: The City of Rosario has faced an increase in violence and crime related to organized crime, especially drug trafficking, in recent years. In response to this situation, the Ministry of National Security implemented an intervention model in 2020 that involved the creation of a ministerial delegation and an increase in the presence of federal security forces, as part of a plan aimed at dismantling and defunding criminal organizations. Objective: In this regard, this paper aims to analyze the state capacities of this delegation to address the issue based on two main dimensions: political and administrative capacities. Methodology: The case analysis is exploratory and descriptive, with a qualitative approach. Conclusions: A detailed analysis of both samples shows that the Ministry's capacities have been low and have not generally met the previously set objectives.

Resumo Introdução: A Cidade de Rosario enfrentou nos últimos anos um aumento da violência e da delinquência vinculada ao crime organizado, especialmente ao narcotráfico. Diante dessa situação, o Ministério da Segurança da Nação implementou, em 2020, um modelo de intervenção que implicou a criação de uma delegação ministerial e um aumento na presença de forças federais de segurança, no âmbito de um plano que visava desarticular e desfinanciar as organizações criminosas. Objetivo: Nesse sentido, este trabalho propõe-se a analisar as capacidades estatais dessa repartição para o enfrentamento da problemática a partir de duas dimensões principais: as capacidades políticas e as administrativas. Metodologia: A análise do caso é do tipo exploratório e descritivo, com um enfoque qualitativo. Conclusões: Uma análise detalhada de ambas as amostras mostra que as capacidades do Ministério têm sido baixas e não cumpriram de maneira geral os objetivos previamente estabelecidos.

Abstract Purpose: To document and analyze the experience of creation, growth and decline of a Solidarity Collaboration Network in Mexico City based on the theoretical-methodological approach of the Actor-Network Theory, in order to understand the role of the key actors, the dynamics that are experienced and the challenges and problems they face in their different stages of development. Methodological design: From a qualitative approach and through a case study, we propose the use of the translation process of the Actor-Network Theory as a theoretical-methodological guide to explore and interpret the findings. Results: The paper reveals the different maneuvers, actions and tensions that led to the construction of the emerging network and its subsequent decline. Five moments describing this process were analyzed: planning of the venture, creation, formalization, growth and decline of the network where both human and non-human actors have influence in different parts of the process. Research limitations: Are linked to the fact that the findings arise from a specific case, however, they can serve as a guide for the study of similar cases and, above all, to generate a greater understanding of the different actions that can arise in the operation of a collaborative network. Findings: The paper reveals the key role of both human and non-human actors and how they influenced both the growth and decline of the network. It also identifies new facets of the emergence and development of a Solidarity Collaborative Network as a function of the incorporation of the translation process. Methodologically, it was possible to observe the value of the Actor-Network Theory as a relevant methodological theoretical tool that can help to analyze and describe how a collaborative network is constituted and stabilized.

Resumen Objetivo: Documentar y analizar la experiencia de creación, crecimiento y declive de una Red de Colaboración Solidaria en la Ciudad de México a partir del enfoque teórico-metodológico de la Teoría del Actor-Red, con la finalidad de conocer el papel de los actores clave, las dinámicas que se viven y los retos y problemáticas a las que se enfrentan en sus diferentes etapas de desarrollo. Diseño metodológico: Desde un enfoque cualitativo y a través del estudio de caso se propone la utilización del proceso de traducción de la Teoría del Actor-Red como guía teórica-metodológica, para explorar e interpretar los hallazgos. Resultados: El trabajo revela las diferentes maniobras, acciones y tensiones que dieron lugar a la construcción de la red emergente y su posterior declive. Se analizaron cinco momentos que describen este proceso: planeación del emprendimiento, creación, formalización, crecimiento y declive de la red donde tienen influencia tanto los actores humanos como no humanos en diferentes partes del proceso. Limitaciones de la investigación: Están vinculadas al hecho de que los hallazgos surgen de un caso específico, sin embargo, estos pueden servir de guía para el estudio de casos similares y, sobre todo, para generar una mayor comprensión de las diferentes acciones que pueden surgir en el funcionamiento de una red colaborativa. Hallazgos: El trabajo revela el papel clave de los actores tanto humanos como no humanos y cómo influyeron tanto en el crecimiento como en el declive de la red. Asimismo, se identifican nuevas facetas que experimentan el surgimiento y desarrollo de una Red de Colaboración Solidaria (RCS) en función de la incorporación del proceso de traducción. Metodológicamente, se pudo observar el valor de la Teoría del Actor-Red como una herramienta teórica metodológica pertinente que puede ayudar a analizar y describir cómo se constituye y estabiliza una red de colaboración.

Abstract This article analyzes the relationship between gentrification and the economic-gastronomic landscape in two neighborhoods in downtown Mexico City. The objective is to conceptually readjust these terms and to recognize the singularities of their manifestations in Latin America. To this end, a theoretical framework is constructed that outlines the three epistemological cores for the analysis of gentrification in the region and that articulates such concept with cultural commodification and gourmetization. Through a descriptive quantitative analysis, we examine the transformation of the food landscape through the presence and diversification of gastronomic and retail businesses in the Condesa and Santa María La Ribera neighborhoods. The results show that there is a trend towards an increase in commercial activity under the model of mini-supermarkets and other businesses that diversify and, at the same time, homogenize cultural and gastronomic offerings in these neighborhoods. However, the pandemic affected these neighborhoods in a particular way: while in Condesa the proliferation of these businesses slowed down, in Santa María La Ribera they increased their presence. It is concluded that this analytical argument offers a view that can strengthen the qualitative study of the effects developed by gentrification and its consequences in other areas of urban daily life.

Resumen En el presente artículo se analiza la relación entre la gentrificación y el paisaje económico-gastronómico en dos colonias del centro de la Ciudad de México. El objetivo es reajustar conceptualmente dichos términos y reconocer las singularidades de su manifestación en América Latina. Con ese fin, se construye un marco teórico que esboza los tres núcleos epistemológicos para el análisis de la gentrificación en la región y que articula tal concepto con la mercantilización cultural y la gourmetización. Mediante un análisis cuantitativo de tipo descriptivo, se examina la transformación del paisaje alimentario a través de la presencia y la diversificación de comercios gastronómicos y comercios al por menor en las colonias Condesa y Santa María La Ribera. Los resultados muestran que existe una tendencia al incremento de la actividad comercial bajo el modelo de los minisúper y otros negocios que diversifican y, a la vez, homogenizan la oferta cultural y gastronómica en estas colonias. Sin embargo, la pandemia afectó de manera particular dichos barrios: mientras que en Condesa se ralentizó la proliferación de estos comercios, en Santa María La Ribera aumentaron su presencia. Se concluye que esta propuesta analítica ofrece una mirada que puede fortalecer el estudio cualitativo de los efectos desarrollados por la gentrificación y sus consecuencias en otras áreas de la cotidianidad urbana.
