- Characterising industrial tourism in the cross-border region: Portugal and SpainPublication . Scalabrini, Elaine C.B.; Alves, Francisco; Neto, Reginaldo; Teixeira, Felipe; García, Joaquín; Velasco, Miguel; Teixeira, João Paulo; Vaz, Roberto; Fernandes, Paula OdetePurpose | Industrial tourism is an emerging sector highlighting the historical industrial landscape, fostering regional development, community revitalisation, and heritage preservation. Factories, mines, and transport infrastructure can be transformed into museums and interactive spaces. Industrial tourism can also include tours of active industrial sites where production remains the primary focus (Friel et al., 2024; Yan et al., 2024). In this context, this study aims to characterise the industrial heritage of the cross-border region, namely in Terras de Trás-os-Montes (Portugal) and Castilla y León (Spain), in the Douro River region, aiming to showcase opportunities for cross-border tourism development. Methodology/Approach | Firstly, a database was drawn up with the industrial heritage of the two regions under analysis. To do this, a form was drawn up based on previous documents and validated by the team of a project related to industrial tourism. From October 2024 to March 2025, the form was sent to 22 municipalities in Portugal and 80 municipalities in Spain. Ultimately, 1079 industrial heritage sites were registered and statistically analysed to determine their characterisation. Expected Results | Of the 1079 industrial heritage sites, 247 are in Portugal, and 832 are in Spain. The heritage elements were categorised and most related to transport infrastructure (31%), wineries (23.6%), food industries (20.5%), and hydraulic heritage (9.3%). These characteristics align with the attractions offered in the two regions surrounding the River Douro. Portugal presents more transport (34.6%) and wineries (22.7%), and Spain to wineries (26.7%) and food industries (25.1%). It is also clear that most (47.3%) of the heritage sites identified are prepared to receive visitors. This study shows that the categorisation of heritage reflects the richness and historical diversity of the region. Among the main types of heritage identified are wineries, illustrating the strong wine-growing tradition of the Douro River, and transport infrastructure, namely old railway stations and bridges, which highlight witness to the impact of industrialisation on regional connectivity. There are also hydraulic structures, such as water mills and historic dams, which show how water resources have been used for industrial activity over the centuries.
- Acceptance and familiarization with wearable devices in Portugal and BrazilPublication . Lopes, Isabel Maria; Rocha, João; Oliveira, Pedro; .This research sought to understand the acceptance of wearable devices in Portugal and Brazil, analyzing aspects such as demographic profiles, experiences with technology and personal perceptions. An adaptation of the UTAUT2 model was made, obtaining responses from university students and frequent internet users through a questionnaire that used the Likert scale. The evaluation of the data indicated a predominance of participants from Portugal, a tendency for acceptance to be more pronounced among younger people, those with a higher level of education and a greater technological proficiency among men and more qualified individuals. The relationship between users and non-users of wearable devices proved to be balanced, with a more marked acceptance by people aged 35 to 59, women and those who have a positive view of technology. The Smartwatch stood out among the devices, followed by the Fitness Bracelet and the Smart Ring. A variation in social influence was observed according to the type of device, being more striking in the case of Smartwatches. Surprisingly, social influence did not prove to be as crucial in the acceptance of wearable devices as initially thought. The findings show a trend towards the adoption of these devices, while also warning of challenges linked to the perceived value and price of products, signaling an area with great potential for future research and innovation.
- The role of artificial intelligence in personalizing the traveler experiencePublication . Lopes, Isabel Maria; Oliveira, Pedro; .The industry that is thought to have profited most from technical advancement is tourism. One notable example of this breakthrough in the past ten years is artificial intelligence (AI), which has become a vital instrument that can drastically alter the experience of visitors. Artificial Intelligence (AI) is revolutionizing travel planning, booking, and experience with chatbots providing round-the-clock customer support and personalized recommendation systems suggesting locations, activities, and places to visit. AI is there prior to, during, and following the excursion. The purpose of this study is to investigate existing technologies, their advantages and disadvantages, and the effects of their implementation in the tourist sector. Specifically, it looks at how AI can be used to personalize the passenger experience. In addition to using state-of-the-art techniques, these results are also obtained by administering a questionnaire to tourists in order to get a specific, quantitative response. Furthermore, the study's limitations are discussed and recommendations for further research are made.
- Graph applications and orientation for exhibition spacesPublication . Càndito, Cristina; Pacheco, Maria F.; .The research investigates the application of some mathematical tools for the analysis and design of architectural paths and spaces. The aim is not to attribute the phenomenon of architectural space configuration to automatic mechanisms but rather to verify the effectiveness of systematic analysis to establish relationships between paths and built environments, particularly in the context of exhibition spaces. For this purpose, the concept of the graph is introduced, within its historical context, linked to its formulation for defining cyclical paths without repetition. Additionally, its role in Space Syntax studies is explored, where it serves as a tool for analysing spatial connections. The formulation of cyclical paths without repetition, and in its dimension, was developed in the Space Syntax studies to indicate spatial connections. A qualitative approach has also been explored. A development in the qualitative field has also been experimented with regard to the characteristics influencing orientation linked to simplifying the distributive graphs of the environments, which can also lead to the evaluation of alternative spatial geometries. This approach enables the assessment of alternative spatial geometries.
- Defining industrial tourism in the cross-border region of Portugal and SpainPublication . Scalabrini, Elaine C.B.; Alves, Francisco; Neto, Reginaldo; Teixeira, Felipe L.; García, Joaquín; Velasco, Míguel; Teixeira, João Paulo; Vaz, Roberto Ivo; Fernandes, Paula Odete; .This paper deals with the definition and valorisation of industrial and pre-industrial tourism in the crossborder region of Terras de Trás-os-Montes (Portugal) and Castilla y León (Spain). Industrial and preindustrial heritage is crucial to collective memory and has significant cultural, historical and tourist value. Industrial tourism is emerging as an initiative that enhances historic landscapes and contributes to urban development, the revitalisation of communities and the preservation of heritage. It is considered an innovative strategy for rehabilitating territories, transforming old facilities into attractions, exploring historic sites or operating companies. The “IN_GENIOS_DUERO_DOURO” project focused on promoting this heritage in the Douro-Duero Euroregion. The methodology included detailed mapping and characterisation, creating a database with 1,079 sites identified in 22 Portuguese and 80 Spanish municipalities. The results show that most sites are in Spain (77.1 %). The municipalities with the most identified sites are Valladolid (250) in Spain and Mirandela (32) in Portugal. The main heritage categories include transport infrastructure (335), wineries (255) and the food industry (221). Around 47.27 per cent of the sites identified are accessible to tourists. The database created is fundamental for valuing, safeguarding and designing tourist routes.
- Adoption of wearables: a UTAUT2 perspectivePublication . Lopes, Isabel Lopes; Oliveira, Pedro; IX Regional Helix'25 Transforming regions through innovation, sustainability and collaborationThis research sought to understand the adoption of Wearable devices, analyzing aspects such as demographic profiles, experiences with technology and personal perceptions. An adaptation of the UTAUT2 model was made, obtaining responses from university students and frequent internet users through a survey using the Likert scale questions was administered to 96 participants. Based on the analysis, there was a tendency for higher acceptance among younger people, those with higher levels of education and greater technological proficiency among men and more qualified individuals. The Smartwatch stood out among the devices, followed by the Fitness Bracelet and the Smart Ring. A variation in social influence was observed according to the type of apparatus. Unexpectedly, social influence has not proven to be as crucial in the acceptance of wearable devices as initially thought. The results show a trend towards the adoption of these devices, while also warning of challenges linked to the perceived value and price of products.

- Study, design, and manufacturing of 3D-printed orthosesPublication . Nogueira, B.; Rocha, João; ., .This study highlights the growing presence of three-dimensional (3D) printing in everyday life, particularly in the manufacture of customized medical devices. In the field of additive manufacturing (AM), Material Extrusion (MEX), ISO/ASTM 52900:2023, (fused deposition modeling (FDM)) has become a widely used technique due to its affordability, accessibility, and ability to create personalized solutions. In this case, a 3D-printed hand orthosis was designed to assist a woman suffering from tendinitis in her thumb. The orthosis was designed to reduce pain and provide support to improve her daily functionality. Material Extrusion (MEX), FDM technology was used to build the device layer by layer, resulting in a lightweight yet durable structure tailored to the patient's needs. One of the key benefits of 3D printing in orthotic design is the ability to create customized, patient-specific solutions at a lower cost than traditional manufacturing. In addition, rapid prototyping allows for quick modifications based on patient feedback, improving comfort and effectiveness. This study reinforces the potential of 3D printing in medical applications and demonstrates how FDM-printed orthotics can help alleviate pain and improve quality of life for people with musculoskeletal conditions. As the technology continues to evolve, personalized healthcare solutions will become more accessible and efficient.
- 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.
