- Academic social entrepreneurship: a contemporary reflection from schumpeter’s economic sociologyPublication . Pinto, Hugo; Sampaio, Fábio; Ferreira, Sílvia; Elston, Jennifer NicoleEntrepreneurship has gained significant relevance in contemporary societies due to its role in generating economic and social value, including job creation, new businesses, and technological and social innovations. Scientific interest in entrepreneurship, which dates back to the 17th century, has increased since the 1990s. This field of study has evolved to encompass not only strict business creation but also impactful social initiatives. This article explores the intersection of academic and social entrepreneurship, examining factors to understand impactful initiatives through the seminal ideas presented by Joseph Schumpeter. The text offers insights and recommendations for advancing the transdisciplinary study of academic social entrepreneurship starting from an Economic Sociology perspective.
- Certification, maintenance and decertification of standardised innovation management systems: Motivations, barriers and benefitsPublication . Mendes de Saboya , Liana; Candido, Carlos Joaquim Farias; Cesário, MarisaThe role of standardised innovation management systems (SIMS) in fostering organisational innovation has been largely overlooked in the literature. This study addresses this gap by investigating the certification, maintenance, and decertification of SIMS. Using a descriptive and inductive methodology, the research analyses primary data from 94 Portuguese organisations with certified SIMS. The findings reveal a strong prevalence of internal motivations for certification, low implementation obstacles, and significant benefits, suggesting that these firms have successfully internalised the SIMS standard into their innovation management processes. Maintenance motivations are also strong, particularly internal ones, which align well with the critical success factors for sustaining certification. The benefits of maintaining SIMS are substantial, particularly internal benefits, as initial external motivations for certification often evolve into internal maintenance motivations. Decertification motivations and propensity are weak among the sample firms. Expectations of negative performance impacts following potential decertification are also low, likely because these organisations have effectively internalised the SIMS standard. This study is the first to explore the maintenance and decertification of SIMS, providing evidence that SIMS can deliver substantial benefits, be efficiently maintained, and continuously enhance innovation and competitiveness. As a result, most organisations exhibit little interest in decertification. The findings offer significant contributions to research and provide actionable insights for practitioners, suggesting that innovation management systems can indeed be standardised with considerable benefits.
- Coagglomeration patterns in portuguese labour-intensive industries: complementarity and specialisation dynamicsPublication . Cesário, MarisaThe aim of this paper is to analyse the patterns of industrial agglomeration in Portugal in order to understand their underlying dynamics. Industries tend to be concentrated geographically, rather than due to random causes, natural advantages or Marshallian forces. Empirically, industry pairwise coagglomeration is measured using the Ellison and Glaeser (1997) metric, with the goal of understanding the complementarity versus specialisation dynamics behind the industrial geographic concentration in Portugal. It is concluded that the most prominent industrial clusters in Portugal are as follows: textiles and clothing, footwear and transport, each one having a different agglomeration dynamic. While some sectors tend to benefit more from the interdependencies along the value chain (meaning vertical industrial relationships, related to complementary dynamics), others are more vulnerable to labour pooling (more to do with horizontal industrial relationships and specialisation dynamics), and others to both. For policymakers, for instance, it is of great use to know exactly the right triggers as the success of any programme results from the suitability of the initiatives being financially supported.
- Does guests-perceived value for money affect WOM and eWOM? The impact of consumer engagement on SNS on eWOMPublication . Quiroga Souki, Gustavo; Oliveira, Alessandro Silva de; Barcelos, Marco Túlio Correa; Martins Guerreiro, Maria Manuela; da Costa Mendes, Júlio; Moura, Luiz Rodrigo CunhaPurpose – Hotels provide high-quality guest experiences to generate perceived value for money (PVM), positively influencing word-of-mouth (WOM) and electronic word-of-mouth (eWOM) communication. This study aims to (1) verify the impacts of the perceived quality by the guests about their experiences in hotels on their PVM; (2) inspect the influence of guests’ perception of hotel prices on PVM; (3) examine the impacts of guest PVM on their hotel experiences on WOM and eWOM and (4) investigate the consequences of the hotel guests’ behavioural engagement on social networking sites (HGBE-SNS) on eWOM. Design/methodology/approach – This quantitative and descriptive study consists of a survey with 371 guests who evaluated their experiences at three hotels in Brazil. PLS-SEM tested the hypothetical model that resorted to the stimulus-organism-response theory (S-O-R), proposed by Mehrabian and Russell (1974). Cluster Analysis compared the PVM, WOM and eWOM of groups of hotel guests with different levels of social media engagement. Findings – Perceived quality by hotel guests positively impacts PVM. Perceived price negatively influences PVM. PVM had a positive and robust impact on WOM. PVM impacts and explains weakly eWOM. In contrast, HGBE-SNS affects and better explains eWOM than PVM. Originality/value – This unprecedented investigation concomitantly exhibits the relationships between perceived quality, price, PVM, WOM, eWOM and HGBE-SNS. Hotels must offer high perceived quality experiences to influence PVM and WOM positively. PVM is unable to stimulate eWOM strongly. HGBE-SNS is pivotal for guests to share their hotel experiences through eWOM. This study suggests marketing strategies for hospitality companies to amplify customer engagement on SNS.
- Economic reconversion and the creation of new trajectories in peripheral mining regions: proposing a theoretical frameworkPublication . Belisario, Helen; Pinto, Hugo; Guimarães, Liliane de OliveiraSeveral regions around the world face the challenge of renewing their economies when the usual growth trajectory begins to weaken. In territories where a particular economic activity predominates - a lock-in, as in the case of mining regions it is considered essential to define new trajectories that allow for economic diversification following the closure of extraction activities. These regions are at a critical juncture to plan for future diversification. This article seeks, based on the literature of evolutionary economic geography (EEG), to expand the understanding of the relationship between mining in peripheral areas and regional diversification, highlighting the role of regional actors in creating new trajectories, whether related to mining or not. The search for a path creation model that considers social, environmental, and economic aspects is becoming increasingly important, both for civil society and for initiatives from national, international, and regulatory bodies. As such, the discussion about path development has gained significant prominence in political agendas and civil dialogues. The article presents a theoretical framework that cyclically integrates the creation of new trajectories, influenced by the actions of local agents, who also contribute to strengthening territorial resilience.
- Editorial 49Publication . Baião Gato, Maria Assunção; Cruz, Ana RitaIssue 49 of CIDADES, Comunidades e Territórios (CITIES, Communities and Territories) features a thematic dossier titled “Between the digital and the urban: readings of the changing space” coordinated by Isabel Carvalho, Sílvia Leiria Viegas, Adriana Nascimento, and Tamara Egler. Digital media are increasingly reshaping how urban life is experienced, represented, and studied. This dossier offers a glimpse into these transformations through 6 articles, 2 essays, and 3 additional contributions exploring the relationship between technology, art and politics. Overall, the authors reflect on how technopower and polarization dynamics take place, namely with reference to a few case studies, while discussing how urban resistance and reconfiguration can be organized around collective initiatives and social movements. These contributions underscore how digital media can enable new forms of knowledge production and civic engagement, inviting researchers to reconsider the boundaries between analysis, intervention, and collaboration in contemporary urban studies.
- The effect of pre-trip virtual reality and on-site smart device use on accessible tourism experiencesPublication . Chan, Chung-Shing; Wong, Shing Yan; Agapito, Dora Lúcia Miguel; Tam, VeledaThis study investigates the contribution of pre-visit virtual reality (VR) experiences and the use of smart devices (SDs) in enhancing accessible tourism for visitors with hearing loss at Yim Tin Tsai Island, a rural destination in Hong Kong. A total of 163 participants, including 78 individuals with varying degrees of hearing impairment and 85 persons without reported disabilities, participated in a self-guided visit. They were randomly assigned to four groups based on whether a VR experience was provided before the visit and whether SDs were used during the visit. Post-visit focus group discussions explored challenges faced, solutions proposed, and perceptions of VR and SD applications. The findings suggest that while VR and SDs offer practical and emotional benefits, visitors with hearing loss do not perceive them as particularly effective in overcoming barriers or significantly enhancing their experiences on the island. Recommendations proposed to improve tourism experiences of visitors with hearing loss include the provision of a multi-sensory environment and information supplementing the visit in VR experiences, as well as adopting a non-intrusive and intuitive approach in presenting information on smart devices.
- From words to visuals: a transformer-based multi-modal framework for emotion-driven tourism analyticsPublication . Calderón-Fajardo, Víctor; Rodríguez-Rodríguez, Ignacio; Puig-Cabrera, MiguelTraditional tourism analytics have primarily relied on isolated sentiment analysis and image processing techniques, often failing to capture the subtle interaction between textual expressions and visual aesthetics inherent in tourist experiences. This study addresses these limitations by proposing a novel multi-modal framework that transforms textual reviews into AI-generated images using standardized prompts, thereby converting affective signals into explicit visual features. Leveraging stateof-the-art models—such as Distilled Bidirectional Encoder Representations from Transformers (DistilBERT) for fine-grained emotion recognition and Contrastive Language–Image Pre training (CLIP) for semantic extraction of visual attributes— our approach maps complex sentiments onto interpretable visual characteristics, integrating explainable features to uncover the underlying structure in tourist perceptions. This approach enhances classification performance and provides a transparent mechanism for understanding how distinct emotional states correspond to specific visual cues. Experimental evaluations on a dataset encompassing four diverse tourist destinations—Berlin, Dublin, Cairo, and Málaga—demonstrate high classification accuracy and robust correlations between text-derived emotions and image-based features, close to more powerful embedding methods. Significant correlations were observed between emotions and visual features, e.g., brightness and contentment, as well as between entropy and shame, indicating that our method efficiently captures the affective resonance between visual and textual modalities. Our findings underscore the transformative potential of converting textual sentiment into visual representations to facilitate more accurate, interpretable, and actionable analytics in the tourism sector. This framework suggests promising avenues for dynamic destination characterization, informed marketing strategies, and enhanced urban planning initiatives, laying the foundation for future advancements in multimodal tourism analytics.
- Improving trust in online reviews: a machine learning approach to detecting artificial intelligence-generated reviewsPublication . Ana Marta Santos; Antonio, NunoIn the hotel industry, social reputation is critical. Consumers increasingly rely on online reviews for accommodation decisions, making Artificial Intelligence (AI) generated fraudulent reviews a significant threat. Distinguishing between genuine and AI-generated reviews is essential for hotels to maintain credibility. This study creates a unique dataset of AI-generated reviews and combines vectorization methods with text-based features to build a Machine Learning model for identifying nongenuine reviews. Results show that incorporating text-based features significantly improves detection accuracy, and simpler vectorization methods can be effective for simpler datasets. This study contributes to academia by providing a novel methodology and publicly available dataset for further research, and to the hotel industry by enhancing credibility and consumer trust through better review filtering.
- Mapping organizational culture, work motivation and innovative behaviour, before and during the crisis: a bibliometric analysisPublication . Rodrigues Guita Almeida, Maria Helena; Kumi, S.; Lampreia Carvalho, FatimaAbstract COVID-19 and the Russia–Ukraine war have profoundly transformed the organisational culture of many organisations, shifting from a focus on security to innovation, which poses a major challenge for managers in all aspects of service delivery, including the healthcare sector. This article addresses gaps in the literature by exploring and mapping the evolution of organisational culture, work motivation, and innovative behaviour before and during the crisis (2012–2018), and summarises the relationship between these variables in 25 selected articles. A literature review on Web of Science with bibliometric analysis and RStudio was conducted. The dynamics, associations, dimensions, and networks that emerge as a way of adapting to new contexts to foster innovation are examined. Results indicate that keywords have evolved over time, and a positive and significant relationship between organisational culture, motivation, and innovation was also identified. The findings suggest that organisations should focus on organisational culture to leverage it as a tool for motivating and fostering innovative behaviour in the workplace.
