RESUMO: O ensino de anatomia vem se modificando ao longo dos anos, introduzindo métodos tecnológicos, principalmente após o período pandêmico. Questiona-se o uso exclusivo da tecnologia em comparação aos métodos tradicionais de dissecação e aulas teóricas presenciais no que diz respeito à aquisição de conhecimento. Este artigo analisou a percepção de conhecimento de alunos de diversos semestres do curso de Medicina Veterinária, comparando alunos que tiveram aulas apenas online com aqueles que tiveram aulas presenciais de Anatomia Descritiva dos Animais Domésticos. Para tanto, questões foram enviadas por meio de formulário, com preenchimento voluntário e anônimo, e posteriormente analisadas estatisticamente. Os resultados indicam que 11,5% dos alunos que cursaram a disciplina remotamente falharam na aplicação dos conhecimentos em outras disciplinas, enquanto nenhum aluno do ensino presencial relatou o mesmo. A maioria dos alunos, tanto dos grupos remotos quanto dos presenciais, lembram-se do assunto, mas revisam o conteúdo com frequência. Em relação ao conhecimento teórico, o grupo online (80,8%) compreendeu melhor à medida que o curso avançava, comparado a 59,6% do grupo presencial. A ligação entre Anatomia e outras disciplinas foi mais destacada pelo grupo presencial (30,8%) em comparação ao online (15,4%). Ambos os grupos concordam que o contacto físico com peças anatômicas é essencial, mas alguns consideram possível ter um primeiro contacto com imagens ou fotografias 3D. Baseado nesse estudo preliminar, conclui-se que as interações iniciais com a área de Anatomia devem incluir técnicas pedagógicas diversificadas com comunicação empática. A utilização de recursos tecnológicos modernos é um aliado do processo de ensino-aprendizagem, e após a abstração dos conteúdos é possível o uso singular da tecnologia na manutenção e atualização do conhecimento anatômico.

ABSTRACT: Anatomy teaching has been changing over the years, introducing technological methods especially after the pandemic period. An ongoing debate revolves around whether exclusive reliance on technology for anatomy classes, as opposed to traditional methods and face-to-face instruction, enhances knowledge acquisition. This study analyzed the knowledge perception of students from various semesters throughout the Veterinary Medicine course, comparing students who only had online classes with those who had face-to-face classes in Gross Anatomy of Domestic Animals. For this purpose, a questionnaire was distributed for voluntary and anonymous completion, and the responses were subsequently analyzed statistically. The results indicated that 11.5% of the students who took Anatomy remotely failed to apply the knowledge in other subjects, while no face-to-face learning student reported the same. Most students, both remote and face-to-face groups, remember the subject but review the content frequently. Regarding theoretical knowledge, the online group (80.8%) understood better as the course progressed, compared to 59.6% of the face-to-face group. The connection between Anatomy and other subjects was more highlighted by the face-to-face group (30.8%) compared to the online group (15.4%). Both groups agree that physical contact with anatomical specimens is essential; however, some believe that initial exposure through 3D images or photographs is feasible. We concluded based on this preliminary study that the initial interactions with the Anatomy field should include diversified pedagogical techniques with empathetic communication. The use of modern technological resources are allies in the teaching-learning process. Furthermore, after abstracting the contents, technology alone can effectively maintain and update anatomical knowledge.

ABSTRACT: This study evaluated the effect of removing apical dominance at phenological stages on the agronomic traits of soybean cultivars. The experiment was conducted in the 2020/2021 growing season inthe teaching-experimental area of the Federal Institute of Education, Science and Technology of Rio Grande do Sul, Campus Ibirubá, under a randomized block design in a split-plot arrangement, with three replications. The main plots were composed of five soybean cultivars (DM53i54 IPRO, Zeus IPRO, Lanza IPRO, DM5958 IPRO, and Delta IPRO), and the subplots consisted of the phenological stages of apical dominance removal (control, V2, V4, and V6). Morphological traits were evaluated at different stages. Differences were observed between cultivars, which followed their pre-defined morphologies. Apical dominance removal reduced aspects such as the number of nodes and legumes on the main stem and the first legumeinsertion height. Cultivars developed branching mechanismsas a compensation strategy, increasing the number of legumes on the branches by up to 130%. The removal of the shoot apex can modify morphological aspects in soybean plants,but their yield tends to be maintained.

RESUMO: O presente artigo objetiva avaliar o efeito da remoção da dominância apical em estádios fenológicos, nos caracteres agronômicos de cultivares de soja. O experimento foi implantado na área didática-experimental do Instituto Federal de Educação e Tecnologia do Rio Grande do Sul, Campus Ibirubá, na safra 2020/2021, sob delineamento de blocos ao acaso, em arranjo de parcelas subdivididas, com três repetições. As parcelas principais eram compostas pelos cinco cultivares (DM53i54 IPRO, Zeus IPRO, Lança IPRO, DM5958 IPRO e Delta IPRO) e as subparcelas, pelos estádios fenológicos de remoção de dominância apical (testemunha, V2, V4 e V6). As características morfológicas foram avaliadas em diferentes estádios. Como resultados, verificaram-se diferenças entre os cultivares, que seguiram suas morfologias pré-definidas. A remoção de dominância apical, reduziu aspectos como o número de nós e legumes na haste principal, além da altura de inserção do primeiro legume. Como estratégia de compensação, os cultivares desenvolvem mecanismos de ramificação, acrescendo até 130% no número de legumes nos ramos. Verifica-se que a remoção do ápice caulinar é capaz de modificar aspectos morfológicos em plantas de soja, contudo, seu rendimento tende a ser mantido.

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

In this work we explore some theoretical and practical aspects of one-pot synthesis. The focal point of the study is the preparation of the thiazole heterocycle, with an emphasis on theoretical aspects of the organic and medicinal chemistry of this important privileged structure. The entire set of experimental procedures and characterization steps explored in this work has the potential to assist in the training and/or technical improvement of undergraduate students, and contribute to the teaching of chemistry in Brazilian higher education. It is worth emphasizing these aspects because the experiments shown in the proposed practices involve simple, rapid, low-risk, and low-cost procedures, making it perfectly feasible to reproduce them in undergraduate classes, even in laboratories with limited material resources. onepot one pot synthesis heterocycle structure andor or students education simple rapid lowrisk, lowrisk low risk, risk low-risk lowcost cost classes resources

ABSTRACT: The mango tree presents a high level of fruit abscission, which is increased in semiarid regions due to environmental stress. The use of biostimulants and phytoregulators has shown to be a promising strategy to improve fruit setting. Thus, the present study defined the best strategy for setting and development of the fruit, with the application of phytoregulators and biostimulants on the ‘Keitt’ mango tree, cultivated in the São Francisco Valley. Two experiments were performed. In experiment 1, a randomized block design was used, with four treatments T1: control, T2: gibberellic acid (AG3) + 2,4-dichlorophenoxyacetic acid (2,4-D), T3: AG3 + 2,4-D+Benzyladenine, T4: Biostimulant + CoMo® (sources of cobalt and molybdenum). In experiment 2, the factorial scheme (2 ×3 + 1) distributed in randomized blocks was established, corresponding to two forms of potassium fertilization (recommended and adjusted), three gibberellin concentrations (0, 10 and 20 mg L-1) and additional treatment (control - recommended potassium fertilization and no setting strategy). The variables analyzed include the relative number of fruits, the number of fruits for domestic and foreign markets, productive potential, production, productivity, fruit volume, fruit mass, and the yield of peel, pulp and stone. The application of 10 mg L-1 AG3 + 10 mg L-1 2,4-D + 10 mg L-1 Benzyladenine in full flowering of the ‘Keitt’ mango tree, increased the setting and the production of the fruit. Regardless of fertilization, sequential applications at 10 or 20 mg L-1 of AG3 proved to be an effective strategy to produce ‘Keitt’ mango tree. Adjusted potassium fertilization and the application at 10 mg L-1 of AG3 promotes the production of fruits with greater mass and volume.

RESUMO: A mangueira apresenta elevado índice de abscisão de frutos, que é potencializado em regiões semiáridas devido ao estresse ambiental. A utilização de bioestimulantes e fitorreguladores tem demonstrado ser uma estratégia promissora para melhorar a fixação de frutos. Assim, o presente estudo foi realizado com objetivo de definir a melhor estratégia para a fixação e desenvolvimento dos frutos, com a aplicação de fitorreguladores e bioestimulante na mangueira ‘Keitt’, cultivada no Vale do São Francisco. Foram realizados dois experimentos. No experimento 1, foi utilizado o delineamento de blocos casualizados, com quatro tratamentos T1: controle, T2: ácido giberélico AG3 + ácido 2,4-diclorofenoxiacético (2,4-D), T3: AG3+2,4-D+Benziladenina, T4: Bioestimulante + CoMo® (fontes de cobalto e molibdênio). No experimento 2, o esquema fatorial (2 ×3 + 1), correspondendo a duas formas de fertilização de potássio (recomendada e ajustada), três concentrações de giberelina (0, 10 e 20 mg L-1) e um tratamento adicional (controle - fertilização de potássio recomendada e sem estratégia de fixação). As variáveis analisadas incluem o número relativo de frutos, o número de frutos para os mercados doméstico e estrangeiro, o potencial produtivo, a produção, a produtividade, o volume de frutos, a massa dos frutos e o rendimento da casca, polpa e semente. A aplicação de 10 mg L-1 AG3 + 10 mg L-1 2,4-D + 10 mg L-1 de Benziladenina em floração plena da mangueira ‘Keitt’, aumentou a fixação e a produção de frutos. Independentemente da fertilização, as aplicações sequenciais de 10 ou 20 mg L-1 de AG3, mostraram ser uma estratégia eficaz para a produção da mangueira ‘Keitt’. A fertilização potássica ajustada e a aplicação de 10 mg L-1 de AG3 favorece a produção de frutos de maior a massa e o volume.

Abstract Background: Generativity has been associated with resilience and life satisfaction in older age, including among lesbian, gay, bisexual, and transgender (LGBT+) older adults. Objective: To examine the psychometric properties of the Loyola Generativity Scale (LGS) and Generative Behavior Checklist (GBC) for Spanish LGBT+ older adults (over the age of 50). Methodology: A psychometric study was conducted with 141 Spanish LGBT+ older adults to examine the construct validity (exploratory factor analysis), convergent validity, and reliability (internal consistency) of the LGS and the GBC. Results: Parallel and exploratory factor analyses suggested a two-factor model with good sample adequacy for both scales. The LGS explained 45.1% of the variance and had an internal consistency of 0.78. The GBC explained 41.76 % of the variance and had an internal consistency of 0.879. A positive and statistically significant correlation was found between life satisfaction and the generative scales. A positive and significant correlation (rs = 0.310) was also observed between both instruments. Conclusion: Both instruments proved valid and reliable for measuring generativity in Spanish LGBT+ older adults.

Considerando estes objetivos e tendo por base os contributos proporcionados pela pesquisa bibliográfica, é possível depreender que a RBU poderá assegurar uma base material de liberdade efetiva, promotora de capacidades de autodeterminação, e contribuir para (novas) sociedades e subjetividades de bem-estar, num quadro de renovação e reforço do Estado de bem-estar social. focase foca se (RBU exigências contemporânea estruturais bibliográfica efetiva autodeterminação novas (novas bemestar, bemestar estar, estar social

Abstract The article focuses on discussing Universal Basic Income (UBI) as a radical redistributive political proposal that envisions alternative ways of organising society and living, more attuned to the diverse demands, challenges and expectations of contemporary life. The primary aim of the analysis is to discuss the main assumptions of the UBI, seeking to understand its implications for material freedom and its potential to induce structural social transformations. Considering these objectives and based on the various insights provided by the bibliographical research, it is possible to deduce that UBI could ensure a material basis for effective freedom, promoting self-determination capabilities, and can contribute to (new) welfare societies and subjectivities, within a framework of renewal and reinforcement of the welfare state.

Abstract In social foraging situations some organisms tend to search their own resources (producer), while others tend to steal and/or join previously discovered food sources (scrounger). Information gain is a factor that allows for efficient identification of sources of food and other organisms. The aim of the study was to evaluate the effect of information gain on the proportion of producer responses using the experimental Guaymas Foraging Task. The task involved searching for and harvesting food in a virtual habitat (videogame), where participants could control a virtual character's movement. Four conditions were manipulated, varying the camera angle and distance. The results show that the producer index was higher in conditions where the camera distance was far. This finding implies that an increase in the overview of the search areas allows the participant to adjust more quickly to contingencies, increasing the proportion of producer responses. On the other hand, the rate maximization model is capable of predicting changes independently of the information gain. However, integrating individual factors into the model could enhance its quantitative predictions.

Resumen Durante la búsqueda de recursos (forrajeo), algunos organismos tienden a buscar sus propios recursos (producir), mientras que otros tienden a robar y/o acoplarse a las fuentes de alimento previamente descubiertas (parasitar). La ganancia de información es un factor que permite identificar eficientemente las fuentes de alimento y otros organismos. El objetivo del trabajo fue evaluar el efecto de la ganancia de información en la proporción de respuestas productoras mediante la tarea experimental Guaymas Foraging Task. La tarea consistió en la búsqueda y cosecha de alimento en un hábitat virtual (videojuego), donde las participantes podían desplazar un personaje virtual. Se manipularon cuatro condiciones que variaron en el ángulo y distancia de la cámara. Los resultados muestran que el índice productor fue mayor en las condiciones donde la distancia de la cámara era lejana. Este hallazgo implica que el aumento en el panorama de las zonas de búsqueda permite a quien participa ajustarse más rápido a las contingencias, incrementando la proporción de respuestas productoras. Por otra parte, el modelo de maximización de la tasa es capaz de predecir los cambios independientemente de la ganancia de la información. Sin embargo, la integración de factores individuales al modelo podría mejorar sus predicciones cuantitativas.

Abstract: Intragenetic Typology focuses its interest on the analysis of properties that are observed in genetically related languages to explain processes of diachronic linguistic change that manifest themselves without trying to develop proposals for historical reconstruction. The analysis of the comparative constructions in Uto-Aztecan languages that are still spoken in the northwestern region of Mexico, Pima Bajo, Tarahumara, Guarijío, Northern Tepehuan, and Yaqui, allows us to show the variety of types of comparative clauses that occur in these languages and to claim in favor of the different grammaticalization paths that give rise to the marker of the standard of comparison, that is, the key operator that contrasts the topic of comparison with the standard of comparison.

Resumen: La Tipología intragenética centra su interés en el análisis de propiedades que se observan en lenguas genéticamente emparentadas para explicar procesos de cambio lingüístico diacrónico que se manifiestan en ellas sin pretender desarrollar propuestas de reconstrucción histórica. El análisis de las construcciones comparativas en lenguas yuto-aztecas que aún se hablan en la región noroeste de México, pima bajo, tarahumara, guarijío, tepehuano del norte y yaqui, permite mostrar la variedad de tipos de cláusulas comparativas que ocurren en estas lenguas y a partir de ellas proponer las distintas etapas de gramaticalización que dan lugar al surgimiento del marcador del estándar de comparación, dígase el operador clave que contrasta al tópico de la comparación con el estándar de la comparación.

RESUMEN En la actualidad las organizaciones deben hacer frente a numerosos riesgos, dada la multitud de actividades que se desarrollan diariamente en un entorno dinámico e incierto, por lo que se hace necesario perfeccionar los modelos de gestión en función de lograr mejoras en su desempeño organizacional. El objetivo de la propuesta que se presenta es una metodología para la gestión de riesgo basado en las normas ISO 31000 en una entidad de ciencia, tecnología e innovación. Se emplearon varios métodos y técnicas que permitieron transitar desde el análisis de los fundamentos teóricos y conceptuales que permitieron presentar la metodológica, emergiendo como un instrumento para coordinar y realizar las acciones necesarias para reducir vulnerabilidades para prevenir, mitigar, atender y recuperar efectos negativos.

The objective of the proposal presented is a risk management methodology based on ISO 31000 standards in a science, technology and innovation entity. Several methods and techniques were used that allowed to move from the analysis of the theoretical and conceptual foundations that allowed to present the methodology, emerging as an instrument to coordinate and carry out the necessary actions to reduce vulnerabilities to prevent, mitigate, attend and recover negative effects.

Abstract Background: Polystemma is characterized by a mixed indumentum of glandular trichomes that turn white, rotate to rotate-campanulate corollas, a gynostegial corona with filiform appendages, and fusiform follicles. The taxon has undergone numerous taxonomic changes in recent years. In current phylogenies, Polystemma has been recovered as paraphyletic and many of its species require a new combination. In this study, we propose the corresponding changes and describe, map, and illustrate three new species within this genus. Questions: Do morphological data support the transfer of Matelea species to Polystemma? Are the plants of Polystemma collected in Durango, Jalisco, and Sinaloa different species? Studied species: Polystemma. Study site and dates: United States, Mexico, Guatemala, El Salvador, Honduras, Nicaragua y Costa Rica, between 2014 and 2024. Methods: More than 3,000 specimens from 20 herbaria and virtual databases were reviewed. Distribution maps were generated, and risk categories were proposed. The cohesive species concept was proposed as an explanatory hypothesis for taxon recognition. Results: A total of 27 species of the genus were recognized, these distributed from the southeastern United States of America to Costa Rica. Eleven new combinations and three lectotypifications are made, and three new species for science are proposed. Identification key, nomenclatural type information, synonyms, habitat, images of all species and distribution maps are also included. Conclusions: The review of this genus allowed for updating and improving the systematics within the subtribe Gonolobinae. Likewise, it highlights Mexico as the center of diversity and endemism for Polystemma.

Se realizan los cambios correspondientes y se describen tres especies nuevas del género. Preguntas: ¿Los datos morfológicos apoyan la transferencia de especies de Matelea a Polystemma? ¿Son especies diferentes las plantas de Polystemma colectadas en Durango, Jalisco y Sinaloa? Especies de estudio: Polystemma. Sitio y años de estudio: Estados Unidos de América, México, Guatemala, El Salvador, Honduras, Nicaragua y Costa Rica, entre 2014 y 2024. Métodos: Se revisaron más de 3,000 ejemplares de 20 diferentes herbarios y bases de datos. Se generaron mapas de distribución y proponen categorías de riesgo. Se planteó como hipótesis explicativa el concepto cohesivo de especie para el reconocimiento de los taxones. Resultados: Se reconocen 27 especies del género, distribuidas desde el sureste de los Estados Unidos de América hasta Costa Rica. Se proponen once combinaciones nuevas, tres lectotipificaciones y tres especies nuevas. Se incluye una clave de identificación e información sobre tipos, sinónimos, hábitat, imágenes de todas las especies y mapas de distribución. Conclusiones: La revisión de este género permitió actualizar la sistemática dentro de la subtribu Gonolobinae. Asimismo, resalta a México como el centro de diversidad y endemismo para Polystemma.

Abstract Background: Ethnobotanical work makes it possible to recognize and take advantage of plants that are potentially important to communities. In the Central region of Guerrero, Mexican plum is a highly appreciated fruit tree due to its versatility as a crop and its commercial potential; However, economic ethnobotanical studies on this species are scarce in the state. Questions: Which morphotype of Mexican plums exist in the study area and which are the most important for its inhabitants? What are the uses and agronomic management of Mexican plum? What are the cultivation and economics characteristics of Mexican plum in the region? Studied species / data description /Mathematical model: Spondias purpurea L. Study site and dates: 3 localities of Juan R. Escudero, Guerrero, México; 2022 and 2023. Methods: Information was collected through 40 semi-structured interviews. The analysis of the information was carried out using descriptive statistics and ethnobotanical indices. Results: Nine morphotypes of Mexican plums were registered, two of them ('Roja Dulce' and 'Roja Grande'), stood out for being the most preferred, the most cultivated and commercialized. The Mexican plum is cultivated preferentially in relation to other fruit crops due to its low water needs, the low economic investment and the short time required to produce fruits. Conclusions: The main use of the Mexican plum is as a foodstuff, there is a very marked preference for two of the nine morphotypes that are grown in the region, their commercialization allows producers to obtain important economic income.

Sin embargo, los estudios de etnobotánica económica sobre esta especie son escasos en la entidad. Preguntas: ¿Cuáles morfotipos de ciruela mexicana existen en la zona de estudio y cuáles son los más importantes para sus habitantes? ¿Cuáles son los usos y el manejo agronómico que se da a la ciruela mexicana? ¿Cuáles son las características del cultivo y económicas de la ciruela mexicana en la región? Especies de estudio: Spondias purpurea L. Sitio y años de estudio: Tres localidades del municipio de Juan R. Escudero, Guerrero, México; 2022 y 2023. Métodos: La información se recabó mediante 40 entrevistas semiestructuradas. El análisis de la información se realizó utilizando estadística descriptiva e índices etnobotánicos. Resultados: Se registraron nueve morfotipos de ciruela mexicana, dos de ellos (‘Roja Dulce’ y ‘Roja Grande’), destacaron por ser los de mayor preferencia, más cultivados y comercializados. La ciruela mexicana se cultiva preferentemente con relación a otros frutales debido a sus bajas necesidades hídricas, a la poca inversión económica y al corto tiempo que requiere para producir frutos. Conclusiones: El uso principal de la ciruela mexicana es el alimenticio, existe una preferencia muy marcada por dos de los nueve morfotipos que se cultivan en la región, su comercialización permite a los productores obtener importantes ingresos económicos.

Abstract Background: In institutionalized elderly people, urinary tract infections are the most common, involving 12% to 30% of this population, with at least one episode per year, where several risk factors influence their occurrence. Objective: To determine the prevalence of urinary tract infections in older people institutionalized in a private institution of social solidarity and to identify the risk factors. Methodology: This is a cross-sectional, observational, and epidemiological study conducted on a convenience sample of people who are institutionalized in a private institution of social solidarity and belong to three different services. Data was collected over 8 months, and the number of patients in the different services was recorded (n = 171). Results: The institution had a urinary tract infection prevalence of 18.1%. Although more cases occurred in women (p = 0.641) and people older than 75 years (p = 0.269), there were no significant differences. Location of hospitalization was identified as a risk factor for developing a urinary tract infection (p = 0.024). Conclusion: Out of the 171 people who were institutionalized, 31 developed a urinary tract infection. It is important to adopt educational and preventive measures.

Resumo Enquadramento: Nas pessoas idosas institucionalizadas, a infeção urinária é a mais comum, envolvendo 12% a 30% desta população, com pelo menos um episódio por ano, onde diversos fatores de risco influenciam a sua ocorrência. Objetivo: Determinar a prevalência das infeções urinárias em pessoas institucionalizadas numa instituição particular de solidariedade social e identificar os fatores de risco. Metodologia: Estudo epidemiológico observacional transversal. Os participantes são pessoas institucionalizadas numa instituição particular de solidariedade social e que pertencem a três valências diferentes. Amostra por conveniência. A colheita de dados realizou-se durante 8 meses, com registo do número total de utentes das várias valências (n = 171). Resultados: A prevalência de infeção urinária na instituição foi de 18,1%. Ocorreram mais casos em mulheres (p = 0,641) e em pessoas com idade superior a 75 anos (p = 0,269), mas sem diferenças significativas. O local de internamento demonstrou ter influência no risco de desenvolvimento de infeção urinária (p = 0,024). Conclusão: Das 171 pessoas internadas, 31 desenvolveram infeção urinária. São necessárias atitudes educativas e preventivas.

Abstract The rebellion of the heir to the Portuguese crown, Afonso, against his father, King Dinis of Portugal (1279-1325), between 1317 and 1323, had a profound influence on the perception we have of the relationship that existed between the sovereign and his heir and successor. The aim of the present essay is to circumvent the occasional limitations imposed by the available sources and adopt a broader approach, taking the Prince's perspective as the starting point whilst seeking to understand, through various testimonies, the manner in which the successor was involved in his father's diplomatic efforts. In so doing, we seek to retrace the different phases of this relationship, while at the same time attempting to highlight instances when the Prince was able to act independently, that is, when his actions were neither conditioned nor regulated by his father's interests.

Résumé Le soulèvement de l'héritier de la couronne portugaise, Alphonse, contre son père, le roi Denis du Portugal (1279-1325), entre 1317 et 1323, a profondément marqué le regard porté sur les relations existant entre le souverain, et son héritier et successeur. Le présent article s’efforce de contourner les limitations parfois imposées par les différentes sources en adoptant une approche de longue durée, en partant justement de la perspective du prince et en cherchant à comprendre, à l'aide de différents témoignages, la manière dont l'héritier a été engagé dans les actions diplomatiques menées par son père, en tentant ainsi de retracer les diverses phases de cette relation, tout en essayant de repérer les actes ou bien les moments où le prince a eu et a pu agir de manière indépendante, c'est-à-dire en évitant que son action soit conditionnée ou contrôlée par les intérêts de son père.

Abstract: The primary objective of this research is to identify elements and concepts that intervene in the existing gender gap in STEM areas (science, technology, engineering and mathematics), to subsequently design and validate a serious game that allows training and raising awareness among university students. A bibliographic review of serious games focused on training in the concept is performed. A three-phase game development methodology is applied to design and validate the serious game “Brechas.” The proposed game has a board mediated by digital tools in which participants answer questions while learning the main concepts about gender gaps in the international, national, and local contexts. The designed tool is refined by the application to 47 participants. In conclusion, this tool allows instructing and raising awareness among students regarding existing disparities in gender issues, especially in STEM areas.

Resumen: El principal objetivo de esta investigación es identificar elementos y conceptos que intervienen en la brecha de género existente en las áreas STEM (ciencia, tecnología, ingeniería y matemáticas), para posteriormente diseñar y validar un juego serio que permita formar y sensibilizar a estudiantes universitarios. Se realiza una revisión bibliográfica de juegos serios enfocados en la formación en el concepto. Se utiliza una metodología de desarrollo de juegos de tres fases, para diseñar y validar el juego serio “Brechas”. El juego propuesto cuenta con un tablero mediado por herramientas digitales en el cual los participantes responden preguntas mientras aprenden los principales conceptos sobre las brechas de género en el contexto internacional, nacional y local. La herramienta diseñada fue refinada a partir de la aplicación a 47 participantes. En conclusión, esta herramienta permite instruir y concientizar a los estudiantes con respecto a las disparidades existentes en temas de género, especialmente en áreas STEM.
