Investigação e formação em questões de (des)igualdade de género com crianças

Publication . Almeida, Ana Margarida; Cardoso, Ana Paula; Lacerda José, Carla Sofia Pereira; Ferreira, Manuela; Margarida Campos, Sofia; Guiné, Raquel

Introdução: As questões de género são um tema fundamental na atualidade, que importa debater desde cedo, a fim de contribuir para o desenvolvimento de uma cidadania plena. Objetivo: Compreender as perspetivas das crianças sobre a igualdade de género, em geral e a nível profissional e salarial, antes e depois de uma intervenção pedagógica interdisciplinar no 1.º Ciclo do Ensino Básico (CEB). Métodos: Estudo qualitativo que consistiu numa investigação sobre as práticas, utilizando diferentes técnicas de recolha de dados. Participaram 24 crianças, do 4.º ano, com idades compreendidas entre os 9 e 11 anos, de uma escola pública de um agrupamento de escolas do concelho de Viseu (Portugal). Resultados: Os dados revelaram que as crianças tinham já conhecimentos prévios sobre o assunto na linha do que a sociedade veicula. Todavia, a intervenção realizada levou a que muitas delas modificassem as suas perspetivas e se tornassem mais conscientes da influência de alguns estereótipos de género. As crianças manifestaram espanto pela diferença salarial entre homens e mulheres, sobre a qual não tinham ainda refletido e, em geral, demonstraram concordância em haver direitos iguais para todos no meio social e profissional. Conclusão: A educação para a igualdade de género é essencial em todo o percurso educativo. Com ela, as crianças têm a possibilidade de desconstruir preconceitos enraizados na sociedade, de desenvolver a sua personalidade de forma integral e de exercer os seus direitos cívicos com assertividade no futuro.

Suggestions for promoting SOC storage within the carbon farming framework: Analyzing the INFOSOLO database

Publication . Cunha, Carlos; Castanheira, Nádia Luísa; Ramos, Tiago Brito; Martinho, Vítor João Pereira Domingues; Ferreira, António José Dinis; Pereira, José Luís da Silva; Sánchez-Carreira, Maria del Carmen

The new world challenges under climate change call for eco-friendly practices that make agriculture’s economic and social dimensions compatible with environmental preservation and ecosystem resilience. Carbon farming has emerged as an interesting alternative for dealing with these new frameworks, as it promotes conservation agriculture with practices that increase carbon sequestration in soils and plants. Considering these motivations, this research intends to bring more insights into the levels of soil organic carbon (SOC) in the Portuguese context, and this variable is interrelated with land use, land attributes, and soil characteristics. Statistical information from the INFOSOLO legacy database was analyzed through statistical methodologies and machine-learning approaches. The findings provide interesting support for the stakeholders about the influence of land use and soil types on the levels of SOC.

Perceptions of higher education students regarding emergency remote education experience

Publication . Pereira, Andreia; Cardoso, Ana Paula; Margarida Campos, Sofia; Ferreira, Manuela

Introducción: Durante la pandemia de COVID-19 fue necesario mitigar las repercusiones de la enfermedad, por lo que se aplicaron medidas de confinamiento, entre ellas la transición a la teleeducación de emergencia. Objetivo: Dado este cambio drástico, fue pertinente analizar las percepciones de los estudiantes sobre la teleenseñanza de emergencia, a través de un estudio realizado al final del año escolar 2020/2021. Métodos: Estudio cualitativo exploratorio utilizando el análisis de contenido de las respuestas a una pregunta abierta que solicitaba a los estudiantes que describieran sus experiencias de aprendizaje durante la cuarentena. Se encuestó a una muestra de conveniencia de 438 personas, que representa el 10% de la población total de una institución de educación superior. Resultados: La experiencia de los estudiantes se describió mayoritariamente de forma negativa en términos de bienestar y académicos, destacando la falta de motivación, el aburrimiento y el estrés, así como las dificultades de aprendizaje, el aumento de la carga de trabajo y la presión. En menor medida, reconocieron la innovación y la comodidad de las rutinas diarias. Conclusiones: Estos datos permiten la reflexión sobre futuras prácticas de educación a distancia y la importancia de mantener la salud mental y el bienestar de los estudiantes durante los periodos de disrupción. Conviene señalar las limitaciones del estudio resultantes del enfoque metodológico, siendo inevitable un cierto nivel de subjetividad.

Analysing the different interrelationships of soil organic carbon using machine learning approaches: Assessing the specific case of Portugal

Publication . Pereira Domingues Martinho, Vítor João; Ramos, Tiago Brito; Castanheira, Nádia; Cunha, Carlos; Ferreira, António José Dinis; Pereira, José Luís da Silva; Sánchez-Carreira, Maria del Carmen

Given the importance of soil organic carbon (SOC) for sustainability, policymakers and researchers are particularly concerned with identifying the conditions that promote carbon storage in the soil. These assessments provide relevant support for the design of policy instruments aimed at increasing soil quality and its carbon sequestration capacity. The new technologies associated with the digital transition can bring relevant added value, namely through artificial intelligence methodologies, where machine learning approaches are important. In this context, this research aims to analyse the several interrelationships of SOC in the specific Portuguese context, with a focus on highlighting its main predictors and providing proposals for stakeholders (including policymakers). To achieve these objectives, statistics from the INFOSOLO database were considered and evaluated using machine learning algorithms to select the most important SOC predictors and identify accurate models. These interrelationships were quantified with cross sectional regressions and optimisation models. The results obtained provide relevant information for the design of adjusted policy measures that promote sustainable practices and increase soil quality. Generally, Portuguese soils have low organic carbon content due to soil features, climate circumstances and land management. Adjusted management of agroforestry activities is possibly the easiest part to deal with in this context.
