- Context-Aware Systems Architecture in Industry 4.0: A Systematic Literature ReviewPublication . Santos, Arlindo; Lima, Claudio; Pinto, Tiago; Reis, Arsénio; Barroso, JoãoFeatured Application This review highlights interoperability, automation, and decision-making as critical requirements for context-aware systems in the manufacturing domain that integrate the principles of Industry 4.0. It discusses relevant patterns and technologies, identifies context gaps, emphasises ontologies' importance, and proposes directions for future research.Abstract Technological evolution has driven the integration of computing devices in various domains, giving rise to heterogeneous and dynamic intelligent environments; together with market pressure, these pose challenges in formulating an architecture that takes advantage of contextual knowledge. In terms of architectural design, we are witnessing a transition from a centralised, monolithic view of systems to a decentralised view that incorporates the vertical and horizontal dimensions of the production environment. Therefore, this review aimed to (i) identify the requirements, (ii) find out about the representation models and context inference techniques, and (iii) identify architectural technologies, norms, models, and standards. The results observed in 25 articles made it possible to identify interoperability, automation, and decision-making as convergence points and observe the adoption of ontologies as a research area for context representation. In contrast, the discussion of context inference techniques remains open. Finally, this study presents recommendations for the design of a context-aware systems architecture that incorporates the principles of Industry 4.0 and facilitates the development of applications.
- Is dissolution the solution? A customer relationship reactivation modelPublication . Lopes, Luisa; Alves, Helena; Brito, CarlosPurpose: The purpose of this study is to identify and explore the factors that lead a lost customer to accept the reactivation of the relationship in business-to-consumer services. With few exceptions, most studies have examined dissolution and reactivation processes in isolation. This study relates to both processes. Design/methodology/approach: The empirical study was carried out in a large Portuguese telecommunication company. Firstly, interviews were conducted with 20 key informants and with 20 customers. Secondly, in order to test the research hypotheses, 830 customers were surveyed, including customers from various business units. Findings: Empirically, it was suggested that the acceptance of a reactivation proposal in contractual relationships is associated with customer characteristics (inertia, involvement andage), previous relationship characteristics (quality and globalsatisfaction), customer’s initial willingness to stay, cognitive(specific satisfaction, justice perceptions) and emotional factors(negative emotions) and barriers to reactivation. Research Limitations: The data were obtained from only one industry in one country. Practical implications: The results suggest that firms need to monitor the specific satisfaction (with dissolution and reactivation activities), improve skills in dealing with emotions, ensure fairness in treatment, proposals and procedures, and consider the characteristics of the customer and the past experience with the provider. Originality/value: This study is one of the few that integrates cognitive and emotional factors, in addition to customer and former relationship characteristics, to discuss successful reactivation strategies.
- 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.
