ABSTRACT: The aim of this paper is to analyze the images of an urban protest intervention called Ni una muerte indiferente (Not one indifferent death) carried out by “Mujeres de Negro Rosario”, Argentina, in November 25, known as the international day for the elimination of violence against women (redefined as the international day for the elimination of violence against women, lesbians, trans, transvestites and non-binary people). With this purpose, we will explore the expressive tools used, with a special focus on the use of masks and their ways of inscription in the public space. Likewise, we will study the relationship between violence and image, based on the analysis of the configuration and perception of the deaths that are propitiated there; the tension between presence and absence; the game between the singular-universal pair; and, finally, the link that is possible to think between image and testimony.

RESUMEN: Este artículo se propone analizar las imágenes de una intervención de protesta urbana denominada Ni una muerte indiferente, realizada por el colectivo “Mujeres de Negro de Rosario”, en Argentina, en el marco del 25 de noviembre, conocido como el día internacional de la eliminación de la violencia contra la mujer (que ha sabido ser resignificado para implicar mujeres, lesbianas, trans, travestis y no binaries). Con este objeto, se explorará el conjunto del herramental expresivo utilizado, poniendo especial foco en el empleo de máscaras y en sus maneras de inscripción en el espacio público. Asimismo, se estudiará la relación entre violencia e imagen, a partir del análisis de la configuración y percepción de las muertes que allí se propician; la tensión entre presencia y ausencia; el juego entre el par singular-universal; y, por último, el vínculo que es posible pensar entre imagen y testimonio.

ABSTRACT Objective: To identify the levels of physical activity among students of Human Medicine at a university in northern Peru during the COVID-19 pandemic. Materials and methods: An observational, descriptive study conducted on 254 firstto fifth-year students of Human Medicine who were administered the International Physical Activity Questionnaire Short Form (IPAQ-SF) in 2021. Results: A total of 48.03 % of the students had a moderate level of physical activity. The sociodemographic characteristics most commonly observed were the female sex in the light (64.56 %) and vigorous (59.26 %) levels of physical activity and the male sex in the moderate (55.37 %) level of physical activity. Concerning the age, the youth stage predominated in all levels (light: 58.44 %, moderate: 62.60 % and vigorous: 61.11 %), contrary to the young adult stage, where all levels obtained the lowest percentage. According to the year of study, second-year students stood out in the light (36.71 %), moderate (36.07 %) and vigorous (58.49 %) levels, in contrast to fourth-year students, who achieved the lowest percentage in all levels (light: 3.8 %, moderate: 26.23 % and vigorous: 3.77 %). Finally, regarding the light level of physical activity, the mean number of hours sitting per day was 7.88 compared to the vigorous level, which attained a mean of 3.23. Conclusions: Most of the students of Human Medicine at a university in northern Peru had a moderate level of physical activity during the COVID-19 pandemic in 2021. The most prevailing sociodemographic characteristic was the female sex with a light level; those in the youth stage and the second year of studies showed all levels of physical activity. Moreover, students with a light level of physical activity remained more hours seated compared to the other levels.

ABSTRACT Purpose: The emergency medical service is a fundamental part of healthcare, albeit crowded emergency rooms lead to delayed and low-quality assistance in actual urgent cases. Machine-learning algorithms can provide a smart and effective estimation of emergency patients’ volume, which was previously restricted to artificial intelligence (AI) experts in coding and computer science but is now feasible by anyone without any coding experience through auto machine learning. This study aimed to create a machine-learning model designed by an ophthalmologist without any coding experience using AutoML to predict the influx in the emergency department and trauma cases. Methods: A dataset of 356,611 visits at Hospital da Universidade Federal de São Paulo from January 01, 2014 to December 31, 2019 was included in the model training, which included visits/day and the international classification disease code. The training and prediction were made with the Amazon Forecast by 2 ophthalmologists with no prior coding experience. Results: The forecast period predicted a mean emergency patient volume of 216.27/day in p90, 180.75/day in p50, and 140.35/day in p10, and a mean of 7.42 trauma cases/ day in p90, 3.99/day in p50, and 0.56/day in p10. In January of 2020, there were a total of 6,604 patient visits and a mean of 206.37 patients/day, which is 13.5% less than the p50 prediction. This period involved a total of 199 trauma cases and a mean of 6.21 cases/day, which is 55.77% more traumas than that by the p50 prediction. Conclusions: The development of models was previously restricted to data scientists’ experts in coding and computer science, but transfer learning autoML has enabled AI development by any person with no code experience mandatory. This study model showed a close value to the actual 2020 January visits, and the only factors that may have influenced the results between the two approaches are holidays and dataset size. This is the first study to apply AutoML in hospital visits forecast, showing a close prediction of the actual hospital influx.

RESUMO Objetivo: Esse estudo tem como objetivo criar um modelo de Machine Learning por um oftalmologista sem experiência em programação utilizando auto Machine Learning predizendo influxo de pacientes em serviço de emergência e casos de trauma. Métodos: Um dataset de 366,610 visitas em Hospital Universitário da Universidade Federal de São Paulo de 01 de janeiro de 2014 até 31 de dezembro de 2019 foi incluído no treinamento do modelo, incluindo visitas/dia e código internacional de doenças. O treinamento e predição foram realizados com o Amazon Forecast por dois oftalmologistas sem experiência com programação. Resultados: O período de previsão estimou um volume de 206,37 pacientes/dia em p90, 180,75 em p50, 140,35 em p10 e média de 7,42 casos de trauma/dia em p90, 3,99 em p50 e 0,56 em p10. Janeiro de 2020 teve um total de 6.604 pacientes e média de 206,37 pacientes/dia, 13,5% menos do que a predição em p50. O período teve um total de 199 casos de trauma e média de 6,21 casos/dia, 55,77% mais casos do que a predição em p50. Conclusão: O desenvolvimento de modelos era restrito a cientistas de dados com experiencia em programação, porém a transferência de ensino com a tecnologia de auto Machine Learning permite o desenvolvimento de algoritmos por qualquer pessoa sem experiencia em programação. Esse estudo mostra um modelo com valores preditos próximos ao que ocorreram em janeiro de 2020. Fatores que podem ter influenciados no resultado foram feriados e tamanho do banco de dados. Esse é o primeiro estudo que aplicada auto Machine Learning em predição de visitas hospitalares com resultados próximos aos que ocorreram.

Abstract: The current issue of cultural identity is an inevitable manifestation of the contradictions and dilemmas of China’s economic and social development in the cultural field. Its root lies in modern China’s backward social development and the invasion of foreign culture, which is manifested by indifference to excellent traditional culture. English is a widely used international language, which is used worldwide. In recent years, with the popularity of English, college English teaching has also received more and more attention. Philosophy is highly theoretical, speculative and difficult to understand, which requires English teachers to be good at utilizing various beneficial resources to mobilize students’ subjectivity and creativity. English is one of the beneficial resources, and proper use of English in cultural identity can have unexpected teaching effects. Therefore, how to use college English education thoughts to enhance national cultural identity is of great significance for promoting the overall development of college English education and promoting national cultural construction. This article discusses how to cultivate national cultural awareness and cultivate national cultural one in the process of English teaching. On this basis, this paper puts forward new ideas to promote the overall development of English teaching in colleges and universities and build national culture. In addition, it emphasized that English knowledge must be integrated with the one learned in order to enable students to better understand different cultures, enhance students’ interest in various countries’ philosophy and culture, and enhance students’ own sense of cultural identity.

Resumen: La cuestión hoy en día de la identidad cultural es una manifestación inevitable del progreso económico y social de China en el ámbito de la cultura. Sus raíces se encuentran en el lento desarrollo social de la China moderna y en la invasión de la cultura extranjera, que se manifiesta en la apatía hacia la gran cultura tradicional. El inglés es una lengua internacional de uso común que se habla en todo el mundo. Con la creciente popularidad del inglés, la enseñanza universitaria de este idioma ha acaparado una mayor atención en los últimos años. La filosofía es muy teórica, hipotética y difícil de entender, por lo que los profesores de inglés deben ser hábiles a la hora de movilizar la subjetividad y la creatividad de los alumnos mediante el uso de numerosos y beneficiosos recursos. El inglés es un recurso valioso, y su uso correcto en la identificación cultural puede tener implicaciones educativas imprevistas. En consecuencia, la forma de emplear las ideas de la enseñanza universitaria del inglés para fortalecer la identidad cultural nacional es fundamental para avanzar en el crecimiento general de la enseñanza universitaria del inglés y la construcción de la cultura nacional.

RESUMO O gladíolo é uma espécie que apresenta cultivares com flores coloridas, e essas hastes podem ser produzidas utilizando práticas de manejo simples e de baixo custo. A cultura não é explorada no Vale do São Francisco, demandando pesquisas que orientem os produtores sobre o cultivo e comercialização. O programa PhenoGlad foi criado para simular a produção de gladíolos com base em dados de temperatura do ano anterior. O objetivo do estudo foi produzir gladíolos em diferentes épocas, avaliar a qualidade das hastes e validar o modelo PhenoGlad. O experimento foi conduzido entre 2020 e 2021 na Universidade Federal do Vale do São Francisco, utilizando o delineamento em blocos casualizados completos, em arranjo fatorial 4x3. Os tratamentos foram compostos por quatro cultivares (Red Beauty; Jester; T704; White Friendship) e três picos de colheita (C1: Festa do Dia da Padroeira de Petrolina-PE, 15 de agosto de 2020; C2: Dia de Finados, 2 de novembro de 2020; e C3: Dia Internacional da Mulher, 8 de março de 2021). Os parâmetros avaliados foram comprimento total da haste, comprimento do pendão floral, diâmetro da haste e longevidade pós-colheita no estádio R2-R5. A interação cultivares e picos de colheita foi significativa para comprimento total da haste e diâmetro da haste. Todas as cultivares se cultivadas em C1 tiveram bom desempenho e apresentaram baixo erro em relação com as observações de campo, validando o modelo PhenoGlad.

ABSTRACT Gladiolus is a species that presents cultivars with flowers of different colors, and these floral stems can be produced using simple and low-cost management practices. Its growth is not widespread in the São Francisco Valley, in Brazil, thus requiring research to guide growers regarding its production and commercialization. The PhenoGlad program was developed to simulate gladiolus production based on temperature data from the previous year. Therefore, the objective of this work was to produce gladioli at different times, assess stem quality, and validate the PhenoGlad model for the region. The experiment was conducted between 2020 and 2021 at the Federal University of Vale do São Francisco, using a complete randomized block design, in a 4×3 factorial arrangement. The treatments consisted of four cultivars (Red Beauty, Jester, T704, and White Friendship) and three harvest peaks (H1: Feast of the Petrolina Patron Saint's Day, August 15, 2020; H2: All Souls' Day, November 2, 2020; and H3: International Women's Day, March 8, 2021). The parameters evaluated were total stem length, rachis length, stem diameter, and postharvest longevity at the R2-R5 stage. The interaction between cultivars and harvest peaks was significant for total stem length and stem diameter. All cultivars grown for H1 performed well and showed a low simulated error compared to field observations, validating the PhenoGlad model. Growing gladiolus in the region is feasible, as the stems meet quality standards and have a suitable shelf life for commercialization. colors lowcost cost practices Valley Brazil commercialization year Therefore times 202 design 43 4 3 4× arrangement Red Beauty Jester T704 T Friendship H (H1 Saints Saint s Day 15 H2 Souls 2 H3 Womens Women 8 2021. . 2021) diameter R2R5 RR R2 R5 R R2-R stage observations feasible 20 T70 (H 1 R2R T7

RESUMEN El mercurio (Hg) es el metal pesado más dañino para los seres vivos debido a su alta toxicidad, persistencia y bioaumentación en la trama trófica. Lantana camara se ha considerado como una especie promisoria para la fitorremediación de distintos metales, pero su respuesta al Hg no ha sido caracterizada. El objetivo de este estudio fue evaluar la efectividad de L. camara para bioacumular, translocar y volatilizar Hg en suelos contaminados artificialmente (1.0 y 8.0 mg/kg de Hg). Luego de dos meses de tratamiento se midió el peso seco y se cuantificó el Hg presente en tallos, raíces, hojas y atmósfera mediante espectroscopía de absorción atómica. El Hg volatilizado fue capturado en cámaras herméticas con flujo de aire continuo, conectadas a una solución trampa (KMnO4 al 5 % disuelto en H2SO4). El factor de translocación fue < 1 y el factor de bioacumulación fue > 1 en ambos tratamientos. Los valores de Hgº volatilizados en alto mercurio indican que aproximadamente 7.1 µg/g planta/día pueden ser liberados a la atmósfera. Nuestros resultados indican que L. camara acumula Hg principalmente en la raíz, mostrando potencial para la fitoestabilización, pero las tasas de volatilización observadas apuntan hacia un uso más restringido de esta especie en estrategias de fitorremediación.

ABSTRACT Mercury (Hg) is the most harmful heavy metal for living beings due to its high toxicity, persistence, and bioaugmentation in the food web. Lantana camara has been considered promising for the phytoremediation of different metals, but its response to Hg has not been characterized. The objective of this study was to evaluate the effectiveness of L. camara to bioaccumulate, translocate, and volatilize Hg in artificially contaminated soils (1.0 and 8.0 mg/kg Hg). After two months of treatment, the dry weight was measured and the Hg present in stems, roots, leaves, and atmosphere was quantified using atomic absorption spectroscopy. The volatilized Hg was captured in hermetic chambers with continuous airflow, connected to a trap solution (5 % KMnO4 dissolved in H2SO4). The translocation factor was < 1, and the bioaccumulation factor was > 1 in both treatments. The Hgº values volatilized in high mercury indicate that approximately 7.1 µg/g plant/day can be released into the atmosphere. Our results indicate that L. camara accumulates Hg mainly in the root, showing potential for phytostabilization, but the observed volatilization rates point towards a more restricted use of this species in phytoremediation strategies.

Abstract In Brazil, the adoption of children/adolescents is a right granted to homoaffective and heteroaffective couples, however, difficulties and social stigmas. This article aimed to analyze the similarities and differences between homoaffective and heteroaffective adopting couples regarding the following points: 1) motivations for adoption; 2) facilitating and hindering aspects of adoption; 3) the couple's routine before and after adoption; 4) relationship of the couple and children with the school; and 5) same-sex couples and prejudice. The qualitative method was used with the assumption that parenting practices were similar for both groups. 64 fathers and mothers were interviewed, divided into two groups: 1. Homoaffective - 38 people, 19 couples (nine lesbians and ten gays), 2. Heteroaffective - 26 people, 13 couples. The comparison between the two groups showed similarities in relation to motivations, difficulties in obtaining new birth records and lack of psychological follow-up by the judiciary. In both groups, parenting is exercised through dialogue and sharing household and school tasks. The distances refer to homoaffective couples: slowness and prejudice during the process of adoption and insertion/adaptation of children in school and lack of adequate calendars to celebrate Father's/Mother's Day. Greater obstacles are faced by homoaffective couples, thus, the need for changes in the judicial system is highlighted to allow the guarantee of comprehensive assistance, seeking to legitimize dignity and citizenship.

Resumo No Brasil, a adoção de crianças/adolescentes é um direito concedido para casais homoafetivos e heteroafetivos, porém, podem surgir dificuldades e estigmas sociais. Este artigo objetivou analisar as aproximações e distanciamentos entre casais homoafetivos e heteroafetivos adotantes referentes aos seguintes pontos: 1) motivações para a adoção; 2) aspectos facilitadores e dificultadores da adoção; 3) a rotina do casal antes e após à adoção; 4) relacionamento do casal e filhos com a escola; e 5) casais homoafetivos e o preconceito. Utilizou-se o método qualitativo com a hipótese de que as práticas parentais eram similares para ambos os grupos. Foram entrevistados 64 pais e mães, divididos em dois grupos: 1. Homoafetivos - 38 pessoas, sendo 19 casais (nove de lésbicas e dez de gays), 2. Heteroafetivos - 26 pessoas, sendo 13 casais. A comparação entre os dois grupos mostrou similaridades em relação às motivações, as dificuldades para obtenção dos novos registros de nascimento e falta de acompanhamento psicológico pelo poder judiciário. Em ambos os grupos, a parentalidade é exercida por meio do diálogo e divisão nas tarefas domésticas e escolares. Os distanciamentos se referem aos casais homoafetivos: 1.lentidão e preconceitos durante o processo de adoção e inserção/adaptação dos filhos na escola, 2. falta de calendários adequados para festejar dia dos pais/mães. Maiores obstáculos são enfrentados pelos casais homoafetivos, assim, destaca-se a necessidade de mudanças no sistema judiciário para permitir a garantia de assistência integral buscando legitimar o direito à cidadania.

Resumen El crimen organizado se ha convertido en un flagelo a nivel internacional conformado por grupos al margen de la ley que realizan todo tipo de actividades que involucran desde tráfico de personas, secuestros, extorsiones, narcotráfico y muchos otros delitos. Producto de este fenómeno, la desaparición y ejecución de personas es cada día más frecuente, en muchos casos los cuerpos son quemados o desmembrados para impedir o hacer más difícil la identificación. La odontología forense se ha convertido en una disciplina transcendental en la identificación de cadáveres y restos óseos, además de contar con múltiples métodos para estimar la edad aproximada de una persona. Se presenta el caso de un descuartizamiento múltiple de tres individuos masculinos donde era indispensable identificar si alguno correspondía a una persona menor de 18 años.

Resumen A propósito de la República de Texas, en este ensayo se hace un estudio sobre el marco teórico jurídico de la secesión y creación de nuevos Estados, tanto en el derecho internacional del siglo XIX como en el derecho internacional de nuestro tiempo. En el derecho internacional del siglo XIX la secesión era fundamentalmente una cuestión de hecho. Y el aval definitivo era el beneplácito de la comunidad internacional, principalmente de las grandes potencias. Hoy en día es imposible admitir la secesión o anexión cuando interviene un tercer Estado o cuando esta intervención se realiza mediante la fuerza militar. Para que la secesión y anexión de Estados sea válida debe ser en cumplimiento de la legalidad internacional, en donde destaca la aceptación del Estado predecesor, el cumplimiento del principio de integridad territorial, salvo los casos en donde ese Estado vulnere los derechos de una población oprimida, y también se reivindica la garantía plena de los derechos humanos y del derecho humanitario.

Abstract About the Republic of Texas in this essay a study is made on the legal theoretical framework of the succession and creation of new States, both in the international law of the 19th century and in the international law of our time. In the 19th century, secession was fundamentally a matter of fact. And the definitive guarantee was the approval of the international community, mainly of the great powers. In time present it is impossible to admit secession or annexation when a third State intervenes or when this intervention is carried out through military force. For the secession and annexation of States to be valid, it must be in compliance with international legality, which highlights the acceptance of the predecessor State, compliance with the principle of territorial integrity, except in cases where that State violates the rights of an oppressed population, and the full guarantee of human rights and humanitarian law is also claimed.

Résumé Concernant la République du Texas, dans cet essai une étude est faite sur le cadre juridique théorique de la sécession et de la création de nouveaux États, tant dans le droit international du XIXe siècle que dans le droit international de notre temps. Dans le droit international du XIXe siècle, sécession était fondamentalement une question de fait. Et la garantie définitive était l’approbation de la communauté internationale, principalement des grandes puissances. Aujourd’hui, il est impossible d’admettre la sécession ou l’annexion lorsqu’un État tiers intervient dans ce processus, ou lorsque l’intervention se fait par la force militaire. Pour que la sécession et l’annexion d’Etats soient valables, elles doivent résulter du respect de la légalité internationale, qui met en exergue l’acceptation de l’Etat prédécesseur, du respect du principe d’intégrité territoriale, sauf dans les cas où cet Etat viole les droits d’une population opprimée, et la pleine garantie des droits de l’homme et du droit humanitaire est également revendiquée.

Resumen Introducción. En Costa Rica se reporta una incidencia de casi un 40 % de la enfermedad causada por Ceratocystis fimbriata en plantaciones comerciales de Gmelina arborea (melina), la segunda especie forestal más plantada en el país. Por lo tanto, surge la necesidad de buscar material genético resistente a este patógeno. Objetivo. Evaluar dos métodos de inoculación de C. fimbriata y su efecto en genotipos élite de melina, para su uso dentro del programa de mejoramiento genético de melina en la cooperativa internacional de mejoramiento genético forestal GENFORES. Materiales y métodos. A partir del aislamiento CIF 001 de C. fimbriata se estableció un ensayo de patogenicidad bajo condiciones de invernadero en Santa Clara de San Carlos, donde se evaluaron dos métodos de inoculación en cinco genotipos élite durante octubre 2019 a enero 2020. Se valoró el efecto del patógeno en el desarrollo de altura total, diámetro basal, cantidad de hojas, incidencia y lesión interna en la planta. El ensayo se evaluó a los 30, 60, 90 y 120 días. Resultados. Se observó mortalidad a partir del día 38 y se alcanzó una incidencia de 26,7 % a los 120 días. El tratamiento con medio sólido presentó el mayor porcentaje de incidencia. Los genotipos 15N y 58 exhibieron una alta susceptibilidad al aisaldo CIF 001, mientras que los genotipos 1 y 57 manifestaron una alta tolerancia. Se determinó que la prueba de patogenicidad de C. fimbriata en melina, puede evaluarse a los 90 días. Conclusión. El tratamiento con medio sólido fue el método de inoculación más eficaz de C. fimbriata (aisaldo CIF 001) en melina. En ninguno de ellos se determinó un grado de resistencia a la enfermedad. El análisis de la lesión interna logró determinar al genotipo 1, como resistente al efecto del patógeno. Su incorporación como técnica de evaluación mejorará significativamente el protocolo de determinación de tolerancia al patógeno.

Abstract Introduction. In Costa Rica, an incidence of nearly 40 % has been reported for a disease caused by Ceratocystis fimbriata in commercial plantations of Gmelina arborea (melina), which is the second most widely planted forest tree species in the country. Consequently, there is a pressing need to explore genetic material that exhibit resistance to this pathogen. Objective. To evaluate two methods of C. fimbriata inoculation and their effect on elite genotypes of melina, for their use within the melina genetic improvement program at the international forest genetic improvement cooperative GENFORES. Materials and methods. A pathogenicity test was established using the CIF 001 isolate of C. fimbriata under greenhouse conditions, in Santa Clara, San Carlos, Costa Rica. Two inoculation methods were evaluated in five elite genotypes from October 2019 to January 2020. The effect of the pathogen was evaluated by measuring total height development, basal diameter, number of leaves, incidence, and internal injury within the plant. The assessment was conducted at 30, 60, 90, and 120 days. Results. Mortality was observed from day 38 and reached an incidence of 26.7 % at 120 days. The treatment using solid medium displayed the highest incidence percentage. Genotypes 15N and 58 exhibited high susceptibility to the CIF 001 isolate, whereas genotypes 1 and 57 exhibited high tolerance. Based on the results, it was determined that the pathogenicity test of C. fimbriata on melina can be evaluated at 90 days. Conclusion. Solid medium was the most effective method for inoculating melina with C. fimbriata (isolate CIF 001). Evaluations showed the need to assess results at least 90 days after inoculation. Based on the analysis of the internal lesion, genotype 1 was identified as highly resistant to the effect of the pathogen. The inclusion of this genotype as an evaluation technique will substantially enhance the protocol for assessing tolerance to the pathogen.

Resumen: La biogeografía reconoce patrones de distribución de los seres vivos en el tiempo y en el espacio, y propone hipótesis acerca de los procesos que causaron dichos patrones. También identifica unidades biogeográficas para proporcionar un sistema jerárquico de regionalización biótica del planeta, delimitando áreas naturales. El objetivo de la presente contribución es presentar la regionalización biogeográfica evolutiva de los Esteros del Iberá, con una puesta al día integrando diversas fuentes de información, describiendo las características fundamentales de la misma, las especies características, los endemismos propios de cada unidad biogeográfica evolutiva, discutiéndose además sus relaciones bióticas y evolución geobiótica. De acuerdo al Código Internacional de Nomenclatura de Áreas (ICAN), se proponen las localidades tipo, con sus respectivas coordenadas geográficas, para la provincia Esteros del Iberá y los distritos Delta del Paraná, Río Uruguay y Sabanas Inundables del Paraná.

Abstract Visual content has been a valuable resource since the creation of the cyberfeminist movement. Together, artivism and the feminist movement aim to decolonise artistic and exclusivist knowledge while also raising awareness of women's issues, especially concerning various forms of gender-based violence. Thus, the main aim of this article is to ascertain how cyberfeminists resorted to feminist artivism to celebrate the International Day for the Elimination of Violence Against Women in Portugal in 2021. To do so, Instagram posts by 10 Portuguese feminist organisations and collectives, posted on 25th November, were analysed through content analysis, and the data divided into online and offline measures - permanent proof of cyberfeminism as a border connecting these mediums. It is worth noting that artivism operates within the current Portuguese feminist movement as a strategic and political tool for the dispersal and propagation of cyberfeminism.

Resumo A modalidade visual é um recurso imprescindível para as ciberfeministas desde a sua origem. A união entre o artivismo e o movimento feminista visa descolonizar os saberes artísticos e exclusivistas, além de propiciar visibilidade às temáticas das mulheres, especialmente em relação às múltiplas formas de violência de género. Assim, este artigo tem como principal objetivo perceber de que forma as ciberfeministas recorreram ao artivismo feminista para assinalar o Dia Internacional para a Eliminação da Violência contra as Mulheres, em 2021, em Portugal. Recorrendo a análise de conteúdo, observamos as publicações do Instagram de 10 associações e coletivos feministas portugueses no dia 25 de novembro, separando os dados em intervenções online e offline, na constatação de que o ciberfeminismo articula fronteiras que interconectam esses espaços de forma permanente. Destacamos que o artivismo opera no atual movimento feminista português como uma ferramenta estratégica e política para disseminação e propagação do ciberfeminismo.
