- The interrelation between environmental, social, and governance (ESG) and transparency: a bibliometric analysisPublication . Cardoso, Celso Araújo; Moutinho, Nuno; Scalabrini, Elaine C.B.; .Sustainability has been a central issue in recent decades, leading to the formal integration of the environmental, social and governance (ESG) dimensions by the United Nations in 2004. Although ‘CSR’, ‘sustainability’ and ‘ESG’ are often used interchangeably, ESG provides criteria for assessing sustainability progress. Transparent disclosure of ESG information is crucial to attracting investment and building trust, despite challenges such as gaming and greenwashing. In this context, this paper aims to analyse the evolution of research on ESG and transparency and identify trends. The study reveals an exponential publication growth using a bibliometric analysis of 497 articles from the SCOPUS database between 2011 and 2025. Europe and China lead the way in publications, influenced by EU regulations and international pressures/domestic standards. There is strong collaboration between the US, Europe, and China about academic production.

- An experimental analysis on the thermal performance of rammed earth wallsPublication . Luso, Eduarda; Cabello, Isabelle; Silva, Rui; Briga-Sá, AnaEarth has been used as a building material since the beginning of civilizations and its utilization was widespread to most regions of the world, promoted by the high availability, easy access, and low cost of the material. As result of the generalised use of raw earth as building material, many earthen building techniques were developed through time, where adobe masonry, rammed earth and wattle-and-daub are among the most important. Currently, it is estimated that one quarter of the world's population lives in buildings made of earth. However, during the last century, earthen materials fell into disuse in several developed countries with the popularization of concrete, steel and fire bricks. Nevertheless, earthen architecture has been receiving increasing attention in the last few decades, driven by its green building potential and by other features of earthen materials, which includes, among others, unique aesthetics and hygrothermal regulation capacity. Several studies have been developed to characterize earthen solutions concerning physical and mechanical properties. However, regarding the thermal behaviour, it is known that the thermal conductivity of rammed earth is a parameter that depends on the characteristics of the soil (particle size distribution, mineralogy, etc.) and moisture content. Thus, given the soils variability, it becomes clear that further investigation should be addressed to characterize the thermal performance of rammed earth solutions, contributing to define more accurate thermal conductivity values for the design of rammed earth buildings. On this regard, this paper presents an experimental study that aims to characterize the thermal behaviour of rammed earth built with different soils and with different thicknesses. A continuous measurement allowed to obtain heat fluxes, inner surface temperatures and the thermal transmission coefficient of the tested rammed earth walls solutions. Values of 0.72 W/mºC and 1.17 W/mºC were obtained for the thermal conductivity, showing the thermal behaviour variability depending on the soil composition. It was also confirmed that thickness significantly influences the earthen solution thermal behaviour, being verified that the thermal transmission coefficient of a 50 cm thick wall is about 30% lower than the one verified for the wall with 35 cm, built with the same soil.
- Evaluation and characterization of the built rural environment of the Montesinho Natural Park, Portugal. The INHAVIT projectPublication . Luso, Eduarda; Ferreira, DéboraIn Portugal, in recent decades, there has been an increase in the population and cities located on the coast and, on the contrary, a decrease in inland locations, with greater severity in rural areas. The causes are complex and not consensual, but it is clear that factors such as the lack of investment in the interior, emigration and migration to a coast that is increasingly autistic in its relationship with the rest of the territory, the abandonment of agriculture and aging of the population constitute sufficient ingredients to promote the desertification of some areas of the country. The abandonment and desertification of villages is not just a problem in Portugal, however. Although Portugal is one of the countries most affected by this problem that affects the entire national territory, it is a European problem that has been increasing since the second half of the 20th century. Concerned about this fact, which puts at risk the high level of abandonment of villages and places in the interior of Portugal, particularly those located in the northeast of Trás-os-Montes, the InHaVit Project - Sustainable approaches for the rehabilitation and revitalization of the cultural heritage built in the Montesinho Natural Park ( PNM), funded by FCT – Fundação de Ciência e Tecnologia, has as its main objective the evaluation and characterization of: (1) the rural built environment of the PNM, at the level of buildings and at the level of villages; and (2) socioeconomic and environmental factors that contribute to the vulnerability of PNM villages and vernacular architecture. In-depth knowledge of these aspects will help to understand the reasons why the villages were progressively abandoned. In the end, the project will propose strategies for risk mitigation, rehabilitation and conservation of built heritage, recognizing that the appreciation and preservation of vernacular architecture is a key element of cultural identity and that it can become a privileged factor for local development. This article aims to show the work methodology relating to the “in-situ” survey carried out so far, relating to point (1), as well as some very particular aspects of this region, namely the slate roofs and the water mills.
- Qual é a medida de área que queremos? O pacri na exploração de conceitos de geometria e medidaPublication . Barros, Paula Maria; Martins, CristinaDe acordo com as aprendizagens essenciais do ensino básico, é importante que os alunos desenvolvam uma predisposição positiva para aprender matemática, o que implica usufruir com gosto dessa aprendizagem. A exploração de jogos na sala de aula pode ter um importante contributo nesse sentido. De realçar, que para além das vertentes motivacional e de cidadania (ler, interpretar e seguir regras, competição saudável, …), há jogos, que podem ter um importante papel na exploração dos próprios conteúdos matemáticos. Consideramos que o Pacri se pode inserir nesta categoria, na medida em que permite explorar o conceito de medida de área, associada à construção de quadriláteros, trabalhar, de forma intuitiva, as coordenadas de um ponto e abordar noções topológicas, como interior, exterior e fronteira de uma figura geométrica. Nesta comunicação, pretendemos apresentar o Pacri e sugerir formas de o explorar na sala de aula. Com base em experiências de aplicação do jogo com futuros professores dos primeiros anos, e na auscultação das suas opiniões, pretendemos, também, refletir sobre a aplicabilidade do Pacri, as dificuldades que podem surgir na sua implementação em sala de aula, possíveis adaptações e extensão para novas tarefas, partindo das figuras geométricas construídas.
- A horta da turma com o scratch: explorando a área e o perímetro de formas retangularesPublication . Ribeiro, Cândida; Branco, Neusa; Barros, Paula MariaO Scratch é um ambiente de programação visual, concebido no Massachusetts Institute of Technology (http://scratch.mit.edu), que, face às suas funcionalidades, é uma das ferramentas recomendadas nas Aprendizagens Essenciais de Matemática do Ensino Básico. Esta pode ser utilizada como um recurso para explorar conceitos em vários temas matemáticos e para desenvolver capacidades matemáticas transversais, como sendo o raciocínio matemático e o pensamento computacional. Tendo em mente estas diretrizes foi elaborada a tarefa “A horta da turma” que promove a utilização do Scratch pelos alunos do 1.º ciclo, visando abordar conhecimentos matemáticos relativos à Geometria e Medida, mais propriamente no domínio da área e perímetro e desenvolver e mobilizar o pensamento computacional para resolver o problema dado. A tarefa foi implementada no contexto de sala de aula numa turma do 4.º ano de escolaridade, numa escola do norte de Portugal. Nesta comunicação pretende-se apresentar a tarefa, descrever o contexto em que foi aplicada e os episódios mais significativos da sua implementação e refletir sobre as aprendizagens proporcionadas aos alunos e sobre os desafios que se colocam ao professor na promoção de tarefas desta índole.
