The rapid advance of nanotechnology has led to the proliferation of a wide range of water-soluble nanomaterials and therefore, a profound impact on the environment, underscoring the need to devise effective methods for isolating and confining these nanomaterials. This study presents the development of a highly effective system capable of removing and storing gold nanoparticles in solution using modified resins with different linking groups, such as tris(2-aminoethyl) amine, 3-mercaptopropionic acid, 11-mercaptoundecanoic acid, and L-cysteine. The catalytic properties of the resins functionalized with the thiol group containing gold nanoparticles were evaluated, using the reduction of the nitro compounds (3,5-dinitrosalicylic acid, 4-nitroguaiacol and 4-nitroaniline) as model reaction. Solid-phase organic synthesis was employed to prepare the modified resins and their interaction with gold nanoparticles was characterized using infrared spectroscopy, thermogravimetric analysis, field emission scanning electron microscopy-energy dispersive spectroscopy, and X-ray photoelectron spectroscopy. The removal capacity of the resins was evaluated using ultraviolet-visible optical emission spectroscopy and inductively coupled plasma techniques. Ultraviolet-visible technique was suitable to assess the catalytic properties of the functionalized resins containing gold nanoparticles. It was determined that the functionalized resins showed remarkable capacity for complex gold nanoparticles, removing them from the solution. The most significant removal was with 11-mercaptoundecanoic acid. watersoluble water soluble therefore environment groups tris2aminoethyl trisaminoethyl tris 2 aminoethyl tris(2-aminoethyl amine 3mercaptopropionic mercaptopropionic 3 acid 11mercaptoundecanoic mercaptoundecanoic 11 Lcysteine.

Abstract This study investigated the effects caused by the thermal shock phenomenon on the temperature distribution in Adhered Ceramic Tiling Systems (ACTS). Cyclic thermal and hygroscopic loads are periodic events resulting from successive and sequential processes of heating by solar irradiation and sudden cooling by heavy rains. Through an experimental program carried out in a ceramic tile prototype composed of porcelain tiles settle with adhesive mortar directly on a concrete wall, monitored the surface temperatures and temperatures at the adhesive mortar-concrete interface were measured during its exposure to heating and cooling cycles according to NBR 15575-4 (ABNT, 2021) procedures. The confinement of thermal energy (heat) inside the structure, after the beginning of cooling, demonstrates that part of the thermal stresses is maintained internally to the structure even after the drop-in surface temperature of the ceramic tile (non-homogeneous distribution), indicating that the movements structural elements of thermal origin will tend to different directions (non-uniform) and, consequently, will cause opposite stresses between layers. This results in a possible increase and concentration of stresses in certain regions that, if critical, will lead to the appearance of damage in the ceramic coating. ACTS. ACTS .

Resumo O estudo investigou os efeitos causados pelo fenômeno do choque térmico sobre a distribuição de temperatura em sistemas de revestimento cerâmico aderido (SRCA). Carregamentos cíclicos térmicos e higroscópicos são eventos periódicos resultado de processos sucessivos e sequenciais de aquecimento por irradiação solar e resfriamentos bruscos por chuvas. Por meio de um programa experimental realizado em um protótipo de revestimento cerâmico composto de placas de porcelanato assentadas com argamassa colante diretamente sobre uma parede de concreto, monitoraram-se as temperaturas superficiais e na interface argamassa colante-concreto durante sua exposição a ciclos de aquecimento e resfriamento, conforme procedimentos da NBR 15575-4 (ABNT, 2021). O confinamento de energia térmica (calor) no interior da estrutura, após o início do resfriamento, demonstra que parte dos esforços térmicos é mantida internamente à estrutura mesmo após a queda de temperatura superficial da placa cerâmica (distribuição não homogênea), indicando que as movimentações estruturais de origem térmica tenderão a ir em direções diferentes (não uniformes) e, consequentemente, ocasionarão solicitações opostas entre camadas. Isso resulta em possível acréscimo e concentração de tensões em determinadas regiões, que, se críticas, levarão ao surgimento do dano no revestimento cerâmico. SRCA. SRCA .

RESUMEN A partir del primer trimestre del 2020 las economías de todo el mundo iniciaron una desaceleración en su actividad debido al confinamiento generado por la pandemia del COVID-19. En varias economías, se implementaron políticas monetarias y fiscales expansivas para tratar de evitar una caída drástica del desempleo y la producción. El objetivo de este trabajo es analizar la relación entre los niveles de inflación y desempleo al inicio de la pandemia, tanto de México, como de Estados Unidos de Norteamérica y, evaluar si existe una diferencia de dicha relación entre ambos países. Se utilizaron datos mensuales de la inflación y el desempleo desde enero de 2016 a diciembre 2020, considerando un Modelo Aditivo Generalizado (MAG) para estudiar la relación entre la inflación y el desempleo en ambos países. Los resultados esperados sugerirían la existencia evidente de la curva de Phillips en el corto plazo en Estados Unidos, no así en México, por lo que no justificaría en este último una política fiscal expansiva para estimular la economía. Se concluye que políticas económicas ortodoxas para estimular a la economía y disminuir el desempleo no forzosamente tendrían los efectos esperados en el caso de México y sí en un incremento de precios.

ABSTRACT As of the first quarter of 2020, economies around the world began a slowdown in their activity due to the confinement generated by the COVID-19 pandemic. In several economies, expansionary monetary and fiscal policies were implemented to try to avoid a drastic drop in unemployment and production. The objective of the work is to analyze the relationship between the levels of inflation and unemployment at the beginning of the pandemic, both in Mexico and in the United States of America, and to assess whether there is a difference in said relationship between both countries. Monthly inflation and unemployment data were used from January 2016 to December 2020, considering a Generalized Additive Model (MAG) to study the relationship between inflation and unemployment in both countries. The expected results would suggest the evident existence of the Phillips curve in the short term in the United States, but not in Mexico, so it would not justify an expansive fiscal policy in the latter to stimulate the economy. It is concluded that orthodox economic policies to stimulate the economy and reduce unemployment would not necessarily have the expected effects in the case of Mexico but would have an increase in prices.

RESUMEN Indispensable es tratar temas procesales respecto a la privación de la libertad, presentándose en la actualidad una discusión latente en Colombia, en la que se valora argumentativamente si se debe restringir para una persona este derecho, una vez se ha dictado el sentido del fallo condenatorio cuando existan prohibiciones respecto a beneficios punitivos, denotándose dos posturas de la jurisprudencia que se contraponen. El objetivo perseguido es resolver que frente a un problema jurídico similar se viene decidiendo con dos alternativas distintas que comprometen el derecho a la libertad y, con ello, el despliegue de las múltiples consecuencias del encierro. Así, se iniciará fijando la categoría de la libertad como un presupuesto máximo; enseguida se ubicarán las dos posiciones contrapuestas frente a una misma situación y, a partir de ello, se vinculará al trabajo la trascendencia del rol del juez argumentador. Con apoyo de una metodología cualitativa, que involucra el estudio del tema por medio de jurisprudencia, doctrina y bibliografía, se colegirá que las limitaciones del derecho a la libertad que están en un escenario procesal en pugna pueden deberse a múltiples posiciones valorativas, y debido a ello, solamente se otea un resultado plausible derivado de la garantía de la motivación.

ABSTRACT It is essential to address procedural issues regarding deprivation of liberty, as there is currently a heated discussion in Colombia regarding whether this right should be restricted once a guilty verdict has been issued, particularly when prohibitions exist regarding punitive benefits. Two contrasting positions are being considered in jurisprudence. The objective is to resolve that, when faced with a similar legal issue, two different alternatives are being decided upon, both of which affect the right to liberty and consequently, the various consequences of incarceration. Thus, we will begin by emphasizing the importance of liberty as a fundamental prerequisite, followed by the identification of the two opposing positions regarding the same situation, and subsequently, the significance of the role of the argumentative judge will be addressed. Utilizing a qualitative methodology, which involves studying the topic through jurisprudence, doctrine, and literature, it will be inferred that limitations on the right to liberty within a contested procedural scenario may stem from various evaluative positions, and therefore, only a plausible result derived from the guarantee of motivation is foreseeable.

Abstract Columns are important structural elements in a building and can be reinforced to increase their capacity. Reinforcement by bonding Fiber Reinforced Polymers (FRP) is attractive because it is easy to apply and does not modify the section. This material has been used in columns for its confinement effect. However, the confinement of columns in non-circular sections is not as efficient as in circular ones. Non-circular geometries behave differently because part of the concrete is not confined. This research aims to study the behavior of rectangular concrete columns reinforced with carbon fiber mats. The aim is to evaluate the performance of rectangular columns with a section side ratio of 2 and to determine the efficiency of the reinforcement. Two groups of columns were tested, one without reinforcement and the other reinforced with a layer of mat. Numerical models were designed with the Finite Element Method (FEM) using Abaqus. The numerical model made it possible to analyze the distribution of stresses in the pillars. Experimental results of maximum force were compared with analytical predictions. The results obtained indicate the efficiency of the reinforcement by improving ductility and increasing load capacity by 30%.

Resumo Pilares são elementos estruturais de grande importância numa edificação e que durante sua vida útil podem ser submetidos a um processo de reforço para aumento da sua capacidade. O reforço com Polímeros Reforçados com Fibras (PRF) é atraente pela facilidade de aplicação e não modificação da seção. O material vem sendo utilizado em pilares pelo efeito de confinamento. Entretanto, em pilares com seções não circulares, o efeito do confinamento não é eficiente como em circulares. Em geometrias de seções não circulares, parte do concreto não fica devidamente confinado. A pesquisa busca estudar o comportamento do reforço de pilares de concreto retangulares pelo confinamento com manta de fibras de carbono. O objetivo é avaliar o desempenho e a eficiência do reforço em pilares retangulares não armados, com altura de 800 mm e relação entre os lados igual a 2. Foram ensaiados dois grupos de pilares, um sem reforço e outro reforçado. Foram idealizados modelos numéricos com o Método dos Elementos Finitos utilizando-se o Abaqus. O modelo numérico permitiu analisar a distribuição das tensões nos pilares. Os resultados experimentais de força máxima foram comparados com previsões analíticas. Os resultados obtidos indicam eficiência do reforço por meio de melhoria na ductilidade e aumento da capacidade de carga em 30%.

Abstract The article we present arises from research that studies the changes that occurred at the University, from the point of view of the students, regarding the teaching methodologies used by the professors. The year 2020 is the starting point of a new way of relating, because as a consequence of the confinement caused by the COVID-19 pandemic, social and work activity changed, and although it was temporary, it had its consequences that may have remained. Thus, in the different social environments, face-to-face activities began to be carried out remotely. At the University of Extremadura, this research team, as teachers, asked themselves what was happening in teaching, and above all, which of these changes remained with us. To do this, the opinions of the students of the University of Extremadura on the changes in teaching methodologies during confinement due to COVID-19 have been analyzed. The research method that has been used is the qualitative study of the answers given by the students to the open questions of the questionnaire validated by this research team. The results obtained indicate that the changes made in teaching methodologies during the COVID-19 pandemic are NOT perceived positively by students in their teaching/learning process. Consequently, it can be concluded that there is no manifestly clear unanimity among students regarding the positive and negative aspects obtained from this experience on the changes in teaching methodologies caused by the COVID-19 pandemic.

Resúmen El artículo que presentamos surge de la investigación que estudia los cambios que ocurrieron en la Universidad, desde el punto de vista de los alumnos, respecto a las metodologías docentes utilizadas por los profesores. El año 2020 es el punto de partida de una nueva forma de relacionarse, pues como consecuencia del confinamiento provocado por la pandemia COVID-19, la actividad social y laboral cambió, y aunque fue de forma temporal, tuvo sus consecuencias que puede que hayan permanecido. Así, en los distintos ambientes sociales, las actividades presenciales pasaron a realizarse de forma remota. En la Universidad de Extremadura, este equipo de investigación, como docentes, se preguntó qué estaba ocurriendo en la docencia, y sobre todo, cuáles de estos cambios se quedaron entre nosotros. Para ello, se han analizado las opiniones de los alumnos de la Universidad de Extremadura sobre los cambios en las metodologías docentes durante el confinamiento debido al COVID-19. El método de investigación que se ha utilizado es el estudio cualitativo de las respuestas dadas por los alumnos a las preguntas abiertas del cuestionario validado por este equipo de investigación. Los resultados obtenidos indican que los cambios realizados en las metodologías docentes durante la pandemia de COVID-19 NO son percibidos positivamente por los alumnos en su proceso de enseñanza/aprendizaje. En consecuencia, se puede concluir que no hay una unanimidad manifiestamente clara, entre los alumnos con respecto a los aspectos positivos y negativos, obtenida de esta experiencia sobre los cambios en las metodologías docentes causados por la pandemia del COVID-19.

Abstract The text addresses the analysis of the global pandemic in December 2021, caused by the Sars-Cov 2 virus, resulting in millions of deaths and transforming social, institutional, and familial life. Following the stabilization of Covid-19 in various regions, there is an emphasis on reflecting on the two years of almost complete confinement, acknowledging that this crisis is a superimposition of health, social, political, economic, educational, and environmental crises. The importance of examining the implications for the pedagogical sphere and professional training in the “new normal” is highlighted. A historical analysis of the pandemic is proposed from psychological, social, cultural, educational, and environmental perspectives. Advocacy for learning from the experience, reviewing virtual pedagogical actions, and building more promising futures by integrating educational and environmental aspects. Finally, it is suggested to use analytical perspectives from authors such as Isabelle Stengers, Donna Haraway, and Ailton Krenak to understand and address the challenges posed.

Resumen El texto aborda el análisis de la pandemia global de diciembre de 2021, causada por el virus Sars-Cov 2, que resultó en millones de muertes y transformó la vida social, institucional y familiar. Tras la estabilización del Covid en varias regiones, se destaca la necesidad de reflexionar sobre los dos años de casi total confinamiento, reconociendo que esta crisis es una superposición de crisis en salud, social, política, económica, educativa y ambiental. Se plantea la importancia de examinar las implicaciones para el ámbito pedagógico y la formación profesional en la “nueva normalidad”. Se propone un análisis histórico de la pandemia desde perspectivas psicológicas, sociales, culturales, educativas y ambientales. Se aboga por aprender de la experiencia, revisar las acciones pedagógicas virtuales y construir futuros más prometedores, integrando lo educativo y ambiental. Finalmente, se sugiere utilizar perspectivas analíticas de autores como Isabelle Stengers, Donna Haraway y Ailton Krenak para comprender y abordar los desafíos planteados.

Abstract Fires affect more natural surfaces than any other disturbance factor on the planet. They result from the interaction of fuel, dry environmental conditions, and an ignition source. In the state of Michoacán conditions are conducive for the annual occurrence of numerous fires. Remote sensing offers global, consistent and objective information on fires, with the generation of series of burned areas, such as the 500m MCD64A1 generated from MODIS data. The objective of this work was to analyze this series to know the fires that occurred in the entity between 2015 and 2022, considering vegetation covers affected (INEGI Series VII) precipitation and temperature. An average of 3 340.87 pixels with fires were recorded annually; 2021, during confinement due to the Covid-19 pandemic, was the year with the most fires (5 269 pixels) and 2022 with the fewest (2 398). The fires are concentrated in the driest and hottest months, mainly May (1551.00 pixels on average) and April (958.38 pixels); the highest number was recorded in April 2021 (2 347 pixels), and the second month with the most detections was May 2020 (2 094 pixels). Most events are associated with agricultural burning (48.41%), mainly in irrigated land, in spring and winter. Forest fires significantly affect temperate forests and associated secondary vegetation (32.85%); in tropical deciduous forest areas (17.14%), fires occur mostly in secondary vegetation. In years with an early onset of rains (2015 and 2018), fewer fires accumulated.

Resumen Los incendios afectan a más superficies naturales que cualquier otro factor de disturbio en el Planeta. Resultan de la coincidencia de combustible, condiciones ambientales secas y una fuente de ignición. En el estado de Michoacán existen las condiciones propicias para la ocurrencia anual de numerosas conflagraciones. La teledetección ofrece información global, consistente y objetiva sobre los incendios, con la generación de series de áreas quemadas, como MCD64A1 de 500m, generada con datos MODIS. El objetivo de este trabajo fue analizar esta serie para conocer los incendios ocurridos en la entidad entre 2015 y 2022, considerando las coberturas afectadas (Serie VII de INEGI), la precipitación y la temperatura. Se contabilizaron al año, en promedio 3 340.87 pixeles con incendios; 2021, durante la pandemia de Covid-19, fue el año con el mayor número de registros (5 269 pixeles) y 2022 con menos (2 398). Los incendios se concentraron en mayo (1551.00 pixeles en promedio) y abril (958.38 pixeles); el máximo número de incendios se detectó en abril de 2021 (2 347 pixeles), seguido de mayo de 2020 (2 094 pixeles). La mayoría de los eventos se asocian a quemas agrícolas (48.41%) en terrenos de riego, en primavera e invierno; los incendios forestales afectan sobre todo a bosques templados y a la vegetación secundaria asociada (32.85%); en zonas de bosque tropical caducifolio (17.14%), los incendios ocurren, en su mayoría, en vegetación secundaria. En los años con un inicio temprano de la temporada de lluvias (2015 y 2018) se acumularon menos incendios.

Abstract The present work reveals the importance of adopting situated perspectives for the creative appropriation of technology aimed at social inclusion, especially in contexts of punitive confinement. This study aims to contribute to the construction of the «Creative Appropriation of Technologies-Articulation of Curricular Contents» model, understanding it as a theoretical-methodological tool. The development of this model was carried out based on a pilot test in a juvenile penal center in an Argentine province, which enabled an empirical and situated approach. This case study provides relevant information for spaces of punitive confinement where a process of coconstruction between formal and non-formal educational practices is required. The results enable the understanding of the needs and challenges in the integration of technology in the education of young people deprived of liberty and highlight the need to build innovative initiatives that include the inscription of these orientations in institutional projects.

Abstract This article is a critical reflexivity approach of our own ethnographic research on SARS-CoV-2 infection carried out during 2020-2021. Experiences, narratives, interpretations and policies for the diagnosis and control of the circulation of the virus in three cities of different urban scale in Argentina are analyzed here. Carried out in the post-pandemic, our analysis aims to converge experiences, tellings and policies to make significant contributions to the study and understanding of the health phenomenon from social anthropology, offering recommendations for the planning and management of future and probable confinements. We conclude that our contribution as social scientists is the understanding of the health phenomenon within the framework of structural inequalities, emerging the need to plan prevention due to confinement at micro, meso and macro social scales.

Resumen: El pasado curso escolar 2019-2020 vivió una situación de confinamiento que obligó a la observancia de una educación online. Esto tuvo varias repercusiones como afectación del alumnado que venía arrastrando alguna dificultad previa (Organización de Estados Iberoamericanos, 2020); imposibilidad de acceso a herramientas tecnológicas para el desempeño educativo diario; incertidumbre sobre cuándo y cómo debía llevarse a cabo la vuelta a la normalidad; regreso a la presencialidad, entre otros. Esto provocó que los docentes manifestaran no sólo la incertidumbre en el ejercicio de su docencia, sino también se viesen hastiados por cambios que no han servido para mejorar su situación profesional, requiriendo sacrificios a nivel personal. Un estudio encaminado a analizar la particular situación educativa en la Comunidad Autónoma de Galicia (España), puso de manifiesto el hartazgo de la clase docente. Esto, con total independencia de la tipología del centro escolar al que pertenecían: público, privado o concertado. La necesidad de realizar varios procesos de muestreo-participación, para obtener la muestra requerida por el estudio, dada su relevancia, fue lo que motivó el análisis sobre las razones que llevan al colectivo de docentes a no participar determinando, a través de un indicador, el grado de hastío de estos.

Abstract: The past school year 2019-2020 has experienced a situation of school confinement, which forced the observance of an online education, with certain repercussions: affectation on students who had been dragging some previous difficulty (OEI), impossibility of access to technological tools for daily educational performance, uncertainty about when and how the return to normality should take place, i.e., return to face-to-face. This caused teachers to express not only uncertainty in the exercise of their teaching, but also to see themselves jaded by changes that have not served to improve their professional situation, requiring sacrifices on a personal level. A study carried out aimed at analyzing the particular educational situation in the Autonomous Community of Galicia (Spain), has revealed the weariness of the teaching class, with complete independence of the type of school to which they are attached: public, private or concerted. The need to carry out various sampling-participation processes, to obtain the sample required by the study, given its relevance, was what motivated the analysis of what leads the group of teachers not to participate, determining, through an indicator, the degree of boredom with them.

Abstract During the pandemic, there were a lot of lockdowns that brought changes to the population’s daily routine, reducing social interactions, changing work and study methods, isolating the family at their home, which brought changes to family dynamics. These changes sparked the interest of nursing students in carrying out a research study. Starting from the question: What is the role of the dog in the family dynamics in times of pandemic? and the objective: identify the guardians’ perceptions about the role of the dog in the family dynamics in a period of confinement, a qualitative, exploratory, and descriptive study was carried out, collecting data through a focus group with six guardians from different families. Bardin’s protocol was used to analyze and process the data. Three categories emerged in this study, highlighting the benefits in terms of mental health, physical and psychological well-being of the family with the presence of the dog, its importance in strengthening family ties and the lessons learned from adopting the dogs. We conclude that, in nursing, it is necessary to highlight the presence of the dog in the family since it brings benefits to its dynamics. pandemic populations population s routine interactions methods home question objective confinement qualitative exploratory families Bardins Bardin health wellbeing well being dogs

Resumo Com o confinamento imposto pelo SARS-CoV-2, houve mudanças na dinâmica familiar. Para os estudantes de enfermagem este foi um assunto que gerou interesse em investigar. Partindo da questão: Qual o papel do cão na dinâmica familiar em tempo de pandemia? e do objetivo: identificar as perceções dos tutores sobre o papel do cão na dinâmica familiar num período de confinamento, enveredámos por um estudo qualitativo, descritivo, com recurso a focus group e amostra de seis membros de famílias diferentes. O tratamento e análise de dados seguiu o protocolo de Bardin. Identificámos que a existência de cão numa família influencia a sua dinâmica através dos benefícios obtidos quer a nível da saúde mental e bem-estar psicológico, quer a nível da saúde física. Igualmente, destacaram-se vantagens, apesar de algumas desvantagens. O vínculo afetivo entre cão e família, advém da reflexão sobre legislação portuguesa, proteção dos direitos dos animais, responsabilidades dos tutores e configuração familiar. Concluímos que na enfermagem, é necessário relevar a presença do cão na família uma vez que traz benefícios para a sua dinâmica. Esta torna-se uma visão inovadora quando pretendemos contribuir para a manutenção da saúde familiar focada nas necessidades de cada indivíduo, família e comunidade.

Resumo: O retorno às atividades presenciais acendeu o alerta para o sedentarismo que se desenvolveu durante o período de confinamento, devido à inclinação ao conforto de permanecer no ambiente familiar. O manuscrito examina o impacto que a pandemia de Covid-19 teve nas instituições educacionais do sul do Peru. Após uma breve introdução, exploramos o medo desenvolvido em relação à interação presencial por parte dos principais agentes impulsionadores do corpus educacional e do desenvolvimento específico da educação nos Andes. Como ramificação da construção teórica, há entre os estudantes uma saudade do passado invernal abalado pelas ondas vibratórias do morcego de Wuhan, pois com o retorno à presencialidade, seu conforto na Internet e usar como desculpa o fato de estar num ambiente virtual para não cuidar de certas responsabilidades acadêmicas e domésticas não será mais possível. No âmbito do ensino, retoma-se o combate frontal aos múltiplos problemas educacionais do país abandonado há dois longos anos; finalmente, para os pais, abre-se no túnel da preocupação, a luz da esperança de ver novamente os filhos com o sagrado uniforme escolar.

Resumen El retorno a la presencialidad ha hecho sonar las alarmas del sedentarismo construido durante el confinamiento debido a la tendencia por la comodidad de no salir del nido. Este ensayo delibera la derivación que ha tenido la pandemia del COVID-19 en las instancias educativas en el sur del Perú. Tras una breve introducción, se aborda el miedo al cara a cara de los principales actores que dinamizan el corpus educacional y el desarrollo específico de la educación en los Andes. Como ramificación del constructo teórico, existe en las personas estudiantes la añoranza hacia el pasado invernal sacudido por las ondas vibratorias del murciélago de Wuhan, porque, con el retorno a la presencialidad, sus comodidades en la red de internet y la excusa de estar en clases virtuales para no ocuparse de ciertas responsabilidades académicas y domésticas ya no serán posibles. En cuanto a la esfera magisterial, se reanuda el combate frontal hacia los múltiples problemas educativos en el país, abandonado por dos largos años; finalmente, para el estrato de progenitores, se aparece en el túnel de la preocupación, la luz de esperanza de ver a sus hijos(as) nuevamente con el sagrado uniforme escolar.

Abstract: The return to presentiality has raised the alarms of the sedentary lifestyle that was built during the confinement and the tendency to the convenience of not leaving the nest. The manuscript explores the repercussions that the Covid-19 pandemic has had on educational institutions in Southern Peru. After a brief introduction, it addresses the face-to-face fear felt by the main actors in the educational corpus, also addressing the specific development of education in the Andes. As a ramification of the theoretical construct, students long for the winter past shaken by the vibrational waves of the Wuhan bat, because with the return to face-to-face, their comforts in the Internet network and the excuse of being in virtual classes to avoid taking care of certain academic and domestic responsibilities, will no longer be possible. As for the teachers’ sphere, the frontal fight against the multiple educational problems in the country, abandoned for two long years, will be resumed. Finally, regarding the parents’ stratum, a light of hope to see their children again wearing the sacred school uniform is starting to shine in a tunnel of worry

Abstract: From Latin American feminisms, this article argues that in a context of financialization of life, the precarious relation between capital, work and life is exacerbated by various devices, such as the debt contracted in response to the imprisonment of a family member. By observing the relevant “corporal itineraries”, this text analyzes the subjection derived from the familiarization of the debt and the intensification of productiveness. It proposes that the imprisonment of a family member leads to a form of indebtedness that redefines the production and extraction of value from the lives of those who are outside, and upholds a morality based on an economics of care.

Resumen: Desde los feminismos latinoamericanos, este artículo sostiene que en un contexto de financiarización de la vida, la precaria relación entre capital, trabajo y vida se ve exacerbada por diversos dispositivos, como la deuda contraída como respuesta al encarcelamiento de un familiar. A partir de la observación de los “itinerarios corporales” pertinentes, este texto analiza el sometimiento derivado de la familiarización con la deuda y la intensificación de la productividad. Propone que el encarcelamiento de un miembro de la familia conduce a una forma de endeudamiento que redefine la producción y extracción de valor de las vidas de quienes están fuera, y defiende una moral basada en una economía del cuidado.

Resumen En este trabajo se describe el proceso de investigación acción participativa (IAP) en la comunidad de Cuilápam de Guerrero, Oaxaca, en un contexto de confinamiento causado por la pandemia de covid-19 (2021), situación que motivó el interés por la actividad agrícola y de traspatio en algunos habitantes. El objetivo de esta investigación fue generar alternativas agroalimentarias, a través de huertos familiares agroecológicos, para reducir la inseguridad alimentaria de las familias de pequeños productores agrícolas de subsistencia. Se integró un grupo solidario de 10 participantes de 7 Unidades de Producción Familiar (UPF), interesados en la transición agroecológica para producir alimentos más sanos y saludables. Siguiendo la metodología IAP, se identificaron las necesidades de capacitación y se programaron los talleres con enfoque agroecológico. A través de este proceso, los participantes obtuvieron nuevos conocimientos para la práctica agrícola, intercambiaron saberes y establecieron valores dentro del grupo de trabajo como, la solidaridad, ayuda mutua, cooperación, reciprocidad y compromiso con el entorno.

Abstract This paper describes the participatory action research (PAR) process in the community of Cuilápam de Guerrero, Oaxaca, in the context of confinement caused by the covid-19 pandemic (2021). This situation motivated interest in agricultural and backyard activity in some inhabitants. This research aimed to generate agri-food alternatives through agroecological family gardens to reduce the food insecurity of families of small subsistence agricultural producers. A solidarity group of 10 participants of 7 Family Production Units (FPU) interested in the agroecological transition to produce healthier and healthier food, was integrated. Following the IAP methodology, training needs were identified, and workshops with an agroecological approach were scheduled. Through this process, the participants obtained new knowledge for agricultural practice, exchanged knowledge and established values within the working group, such as solidarity, mutual aid, cooperation, reciprocity, and environmental commitment.
