- PROMORE: a procedural modeler of virtual rural environments with artificial dataset generation capabilities for remote sensing contextsPublication . Adão, Telmo; Cerqueira, João; Adão, Miguel; Silva, Nuno; Pascoal, David; Magalhães, Luís G.; Barros, Tiago; Premebida, Cristiano; Nunes, Urbano J.; Peres, Emanuel; Morais, RaulRemote sensing (RS) is a rapidly evolving field that facilitates the study of phenomena on the Earth’s surface. Through various platforms, including satellites, manned aircraft, and remotely piloted aerial vehicles (RPAV), RS has been strategically applied to critical sectors like agriculture and forestry, which are essential for humanity’s sustenance. Key applications include crops classification, yield estimation and livestock monitoring and quantification. In the era of artificial intelligence (AI), the development of deep learning (DL) models for such applications often requires extensive field data collection and labor-intensive image labeling, which are both time-consuming and resource-intensive. To address these challenges, this paper presents Procedural Modeling of Rural Environments (PROMORE), a parameterizable, ontology driven system designed to generate 3D virtual environments encompassing forestry, farmland – mainly focused on vineyards – and village settings. This system also implements functionalities to automate the extraction of training data for deep learning applications in remote sensing, with the declared aim of providing complementary capabilities to data augmentation techniques, encompassing both traditional methods (e.g., flips, rotations, zooming) and advanced approaches such as generative adversarial networks (GANs). By simulating RPAV flights and managing virtual object visibility, PROMORE enables the automatic labeling, delineation, and highlighting of elements of interest (e.g., vine plants, trees, buildings), facilitating the generation of datasets tailored for tasks such as semantic segmentation, and object detection.
- Digital marketing in wine tourism – Trás-os-Montes and Dão case studyPublication . Fontes, Filipa; Esteves, Elsa Tavares; Morais, Elisabete PauloHaving quality wine is important for a wine company; however, it is necessary to have a communication strategy and be aware that digital marketing activities are constantly evolving and that companies need to adapt to stay close to their audience. The wine sector increasingly sees digital marketing as a valuable and convenient tool for promoting companies and as a facilitator to reach consumers. The Regional Wine Commissions (RWCs) are entities whose mission is to promote and publicise the wine products of their region. The aim of this paper is to analyse the performance of two RWCs, both located in Portugal – the Trás-os-Montes region and the Dão region – on a digital level (Facebook, Instagram and website) and their use of search engine optimisation (SEO) techniques. The intention is also to identify how they promote regional producers and the wine tourism offer on their websites.
- Does CSR committee presence, stakeholder engagement, gender equality (SDG 5) and firm value influence ESG performance reporting? An EU pre and during Covid-19 analysisPublication . Monteiro, Albertina Paula; Cepêda, Catarina; Borges, Ana Pinto; Vieira, Elvira PachecoThis paper aims to analyse the corporate social responsibility (CSR) Committee presence and gender equality influence on environmental, social and governance (ESG) performance reporting in a pre- and during Covid-19 crisis in European Union (EU) listed entities. Design/methodology/approach – To achieve the goal, an empirical analysis was conducted with 1,221 listed companies in EU as support for the economics years 2017–2021. Statistical technique used to analyse the relationship between the variables under study was regression analysis with panel data. Findings – Results show that CSR committee presence, stakeholder engagement and gender equality are positively associated with ESG performance reporting, but the Covid-19 crisis and the book value per share do not influence the dependent variable. The model variables determine 99% of the ESG performance reporting. Practical implications – The results are useful for managers, governments and organizations in developing sustainability reporting standards. As companies navigate the complex landscape of sustainability challenges, integrating sustainable development goals into their strategies and ESG reports provides a roadmap for creating positive, lasting impacts on a global scale. Originality/value – This research covers listed firms from throughout the EU and the pre- and during-Covid era.
- After COVID-19 lockdown: an exploratory study about the influence of mindfulness-feelings toward an individual’s outdoor lifestyle and empowermentPublication . Borges, Ana Pinto; Vieira, Elvira Pacheco; Rodrigues, Paula; Almeida, António Lopes de; Sousa, AnaThis study aimed to detect the relationships between mindfulness and events participation, and then between the later and psychological empowerment. Design/methodology/approach – The proposed model’s underlying hypotheses were empirically tested with data collected through an online survey addressed to a convenience sample of frequent leisure participants (n 5 199). The authors applied the structural equation model (SEM) to confirm the aforementioned relationships. To assess the adequacy of the psychometric properties of the measures, the authors performed a confirmatory factor analysis of the measurement model, with a maximum likelihood estimation method. Findings – Under the effects of the lockdown period environment, the results express a positive relationship between a mindful state of mind – related to observation/attention – and the yearnings and perceptions about the participation in events. This relationship for consistency was proven to be moderated by the perception of the participation importance to the individual subjective well-being/mental health. Due to participation insights, there was a positive effect on psychological empowerment, supporting the relationship that had been hypothesized. Originality/value – The authors propose and test a new model that contributes to the theory and examines how mindfulness behavior can effect more alluring and intense participation in events and what are the anticipated outcomes in terms of psychological empowerment.
- Exploring the potential of Flickr user–generated content for tourism research: insights from PortugalPublication . Martins, Márcio Ribeiro; Santos, ArlindoThe purpose of this research is to present and discuss the methods of identifying visitors and local population in tourism studies using geotagged photos from the Flickr social network, and differentiating them according to their country of residence. This study focuses on 1,434,268 photos taken in Portugal between 2010 and 2022 and uploaded by 31,286 Flickr users. Different approaches to cleaning the database, to distinguishing tourists from locals, and to identify their country of residence were employed and discussed. After data cleaning, the photos database corresponds to 1,144,981 photos shared by 29,890 users. Using the information provided in each user’s profile and the time zone, 12,144 users (41%) were classified as visitors and 2,659 users (9%) as locals. The monthly distribution of the percentage of photos uploaded by users classified as visitors coincides with the high season of tourist activity in Portugal. The distribution of users by country of residence coincides with the main inbound markets in Portugal: Spain, United Kingdom, France and Germany. Building on a country-wide case study, the contribution of this paper is a refined understanding of the use of Flickr usergenerated content in tourism studies, proposing a frame-work to facilitate all researchers to use this data source more frequently.

- Rural regeneration through creative tourism: Local discourses on cultural heritagePublication . Rodrigues, Cristina; Mendes, Teresa; Liberato, Dália; Brandão, Filipa; Esteves, Elsa Tavares; Liberato, PedroAlternative forms of tourism are gradually emerging, as tourism transforms itself and adopts new forms of consumption and development. It is therefore necessary to understand the new approaches to tourism sustainability in order to achieve more transformative results for destinations and their local communities. This research aims to identify creative tourism as the most equitable approach to achieving the sustainability and the regeneration of rural territories. Thus, the general objective is to understand how Cultural Heritage, as a tourist resource, can be used to promote regenerative impacts in a rural region of Portugal, particularly in Trás-os-Montes. As part of a qualitative methodology, the focus group interview technique was applied to three of the destination's stakeholders: Municipalities; Tourism agents; and Residents, to discuss the tourism promotion of a very particular heritage and its implications. The main results identify the greatest consensus among the participants, essentially regarding the suitability of creative tourism for the Cultural Heritage under study, from different perspectives. As well as five potential regenerative benefits for the destination: (i) Local Sourcing Practices, (ii) Social and Cultural Involvement, (iii) Sustainable Economic Performance, (iv) Inclusiveness Management, and (v) Education and Capacity Building, associated with nine United Nations Sustainable Development Goals (SDGs).
- Feira Medieval de Torre de Moncorvo: Segmentação do visitantePublication . Moreira, Raquel; Esteves, Elsa Tavares; Esteves, SaleteUm evento é considerado uma parte importante na criação de uma boa experiência. É necessário ter em conta que o comportamento do consumidor está em constante alteração e que também as necessidades vão variando ao longo do tempo. Desta forma, muitos estudos têm-se focado na segmentação de mercado de forma a entender quem são os visitantes de um evento. O principal objetivo do presente trabalho é identificar segmentos de visitantes da 9ª edição da Feira Medieval de Torre de Moncorvo. A abordagem quantitativa está na base da investigação e aplicou-se assim um inquérito por questionário no recinto da Feira nos dias 8, 9 e 10 de abril de 2022, onde foram obtidas 300 respostas. Pela análise dos dados registaram-se três segmentos: os “Os Culturais” - indivíduos caracterizados por um maior interesse pela vertente cultural, procurando um maior contacto com a cultura; os “Os Relaxados” - constituídos por indivíduos que dão mais importância ao fator relaxamento quando procuram este tipo de eventos; e “Os Exigentes” - aquelas pessoas que acabam por não ter gostos nem preferências por qualquer um dos fatores de eleição e por consequência apresentam um menor grau de satisfação. Os resultados obtidos poderão dar novas orientações aos organizadores do evento, para que possam melhorar a oferta existente.
- The role of value co-creation, delight and satisfaction on tourism loyalty: an empirical study in hospitalityPublication . Lopes, Luisa; Mangini, Eduardo; Esteves, SaleteThis paper investigates the relationship between value co-creation, delight, satisfaction, and loyalty in the hospitality sector, considering the perceptions of hotel customers in Portugal. To gain deeper insights into hotel customers' perception of delight, developing and testing an integrated model was undertaken by examining the relationship between these variables to expand the theory of customer delight when related, as a novelty, with value co-creation, customer satisfaction, and loyalty. The data for this investigation was collected through a questionnaire administered to 178 hotel customers. The gathered data was then subjected to both descriptive and inferential analysis. To test the integrated model, the researchers used the Partial Least Squares (PLS) technique and validated it using Smart PLS 4.0 software. On the one hand, the results show that value co-creation has a direct positive effect on customer delight and, subsequently, influences the effect of customer delight on customer loyalty. On the other hand, value co-creation has a direct positive effect on customer satisfaction, which, in turn, positively influences loyalty. All four proposed hypotheses are supported.
- Converging extended reality and Machine Learning to improve the lecturing of geometry in basic educationPublication . Cunha, Carlos R.; Moreira, André Silva; Coelho, Sílvia; Mendonça, Vítor; Gomes, João PedroTechnology is constantly supporting in the innovation of the teaching-learning process. Today’s students are more demanding actors when it comes to the environment they have at their disposal to learn, experiment and develop their critical thinking. The area of Mathematics has successively suffered from students’ learning difficulties, whether due to lack of motivation, low abstraction ability or lack of new tools for teachers to bring innovation into the classroom and outside it. While being true that digitalization has entered schools, it often follows a basic and simple process of digital replication of approaches and materials that were previously only available on physical media. This work focuses on the use of Extended Realities, more precisely, Mixed Reality, for teaching Mathematics, and very particularly in the teaching of Geometry, through the proposition of a conceptual model that combines the use of Extended Reality and Machine Learning. The proposed model was subject to prototyping, which is presented as a form of laboratory validation as a contribution to innovate the way of how the geometry teaching-learning process is developed and to promote the integration of Extended Reality technologies into the Education Sector as practical tools, as well due to its potential use to obtain useful insights for teachers, and students, throughout the process.
