- Evaluation of the impact of sustainable drainage systems (SuDSs) on stormwater drainage network using giswater: a case study in the metropolitan area of Barcelona, SpainPublication . Araújo, Suelen; Lança, Rui; Silva, Carlos Otero; Torret, Xavier; Granja Martins, Fernando Miguel; Maria Neto Paixão Vazquez Fernandez Martins, HelenaTo mitigate the impacts of urbanisation and the attendant surface sealing, appropriate measures are required when adapting urban spaces and drainage infrastructure. In this context, the deployment of Sustainable Drainage Systems (SuDSs) has emerged as a viable alternative, delivering highly positive outcomes by enhancing hydrological, hydraulic and landscape performance while restoring ecosystem services to the community. This study evaluates the relative performance of five SuDS typologies, green roofs, bioretention cells, infiltration trenches, permeable pavements, and rain barrels, implemented in a 64 ha subbasin of the metropolitan area of Barcelona, Spain. Using Giswater integrated with the SWMM, the stormwater drainage network was modelled under multiple rainfall scenarios. Performance was assessed using two qualitative indicators, the junction index (Ij) and the conduit index (Ic), which measure surcharge levels in manholes and pipes, respectively. The results show that SuDS implementation affecting 42.8% of the drained area can enhance network performance by 35.6% and reduce flooded junctions by 67%. Among the typologies, rain barrels and bioretention cells were the most effective. The study concludes that SuDS construction, supported by open-source tools and performance-based indicators, constitutes a replicable and technically robust strategy for mitigating the effects of surface sealing and increasing urban resilience.
- GIS-based site selection for agricultural water reservoirs: a case study of São Brás de Alportel, PortugalPublication . Dziuba, Olga; Custódio, Cláudia; Silva, Carlos Otero; Granja Martins, Fernando Miguel; Lança, Rui; Maria Neto Paixão Vazquez Fernandez Martins, HelenaIn the São Brás de Alportel municipality, water scarcity poses a significant constraint on agricultural activities. This study utilises Remote Sensing (RS) and Geographical Information Systems (GISs) to identify existing irrigated areas, delineate catchment basins, and select the most suitable sites for the installation of new surface water reservoirs. First, the principal territorial components were characterised, including physical elements (climate, geology, soils, and hydrography) and anthropogenic infrastructure (road network and high-voltage power lines). Summer Sentinel-2 satellite imagery was then analysed to calculate the Normalised Difference Vegetation Index (NDVI), enabling the identification and classification of irrigated agricultural parcels. Flow directions and accumulations derived from Digital Elevation Models (DEMs) facilitated the characterisation of 38 micro-catchments and the extraction of 758 km of the drainage network. The siting criteria required a minimum setback of 100 m from roads and high-voltage lines, excluded farmland currently in use, and favoured mountainous areas with low permeability. Only 18.65% (2854 ha) of the municipality is agricultural land, of which just 4% (112 ha) currently benefits from irrigation. The NDVI-based classification achieved a Kappa coefficient of 0.88, indicating high reliability. Three sites demonstrated adequate storage capacity, with embankments measuring 8 m, 10 m, and 12 m in height. At one of these sites, two reservoirs arranged in a cascade were selected as an alternative to a single structure exceeding 12 m in height, thereby reducing environmental and landscape impact. The reservoirs fill between October and November in an average rainfall year and between October and January in a dry year, maintaining a positive annual water balance and allowing downstream plots to be irrigated by gravity. The methodology proved to be objective, replicable, and essential for the sustainable expansion of irrigation within the municipality.
- TikTok in higher education: a learning tool to connect with industry and develop students' digital skillsPublication . López-Carril, Samuel; Carpenter, Jeffrey P.; Watanabe, Nicholas M.; Ribeiro, TiagoTikTok has rapidly become a mainstream social media platform, particularly popular among younger populations. However, young people's perceptions of TikTok's use as a teaching–learning tool remain largely unexplored. To address this literature gap, this study involved an educational intervention in which TikTok was integrated into sport management classes at a Spanish university through active learning methodologies. Specifically, it sought to assess changes in students’ perceptions before and after the intervention across three key dimensions: TikTok’s usefulness as a teaching tool, its contribution to professional development, and its potential for industry engagement. To assess students' perceptions of TikTok, a pre-test and post-test were conducted with 48 students (71% male, 29% female) enrolled in the course. Quantitative findings revealed statistically significant positive changes across all three dimensions, suggesting that the intervention positively impacted students’ perceptions of TikTok’s educational, professional, and industry-related value. These findings were reinforced by qualitative data collected through open-ended responses, in which students highlighted TikTok as a creative, motivating, and professionally relevant learning tool. The results of this study offer both theoretical and practical insights that may be valuable to educators and educational institutions considering the strategic integration of social media such as TikTok into higher education.
- Women and pro-environmental initiatives in tourism: the intersection of gender dynamics and environment issuesPublication . Bagheri, Fatemeh; Esfehani, Minoo; Ghaderi, Zahed; Mohajer, Boshra; Abdi, NaserWomen’s involvement, gender equality, and environmental challenges are critical concepts in tourism development, particularly in patriarchal systems where hierarchical value systems create challenges for both nature and women. However, the theoretical framework addressing these issues remains underexplored. This study examined how women interpret their motivations and challenges in these contexts while contributing to tourism-related environmental conservation and navigating patriarchal gender norms. It investigated the lived experiences of Iranian women actively engaged in tourism related conservational initiatives. The findings revealed that their commitment to pro-environmental initiatives is driven by an intrinsic connection to nature and a desire to resist gender inequalities and challenge male-dominated structures. Despite facing challenges stemming from patriarchal structures, they demonstrate collective resilience against gender stereotypes. Additionally, their participation in tourism pro-environmental projects fosters trust and social recognition, driving incremental social change. This study makes a strong theoretical contribution by exploring gender issues through the lens of ecofeminism theory.
- Socio‐spatial vulnerabilities, peripheralization and post‐crises resilience: lessons from the portuguese casePublication . Carmo, Renato Miguel; Pinto, Hugo; Ferrão, JoãoExisting socio-spatial vulnerabilities in the pre-pandemic moment led to different impacts of COVID-19 on territories, reinforcing ongoing processes of peripheralization. This article develops a new approach to understand the linkages between socio-spatial vulnerabilities and the socio-economic impacts of this crisis. Using data from Portuguese municipalities, a typology of vulnerable territories is defined based on the degree of potential exposure and susceptibility to external shocks. The different groups of municipalities are then related to the impact of the pandemic crisis on unemployment dynamics in 2020 and 2021. The results confirm the existence of increased socio-spatial vulnerability in areas highly dependent on tourism as well as in fragile socio-economic intra-metropolitan areas. The article has implications for thinking forward about socio-spatial vulnerability, peripheralization and the emergence of left-behind places, stressing the need to foster resilience in order to transform regional economies in post-crises recovering periods.
- Examining identity and perceived risk on technology acceptance and behavioural intentions of fans: an extended TAM perspectivePublication . Shuya, Zhao; Ribeiro, Tiago; Almeida, VictorPurpose – The rise of digital innovations in the sports industry has led to the growing adoption of fan tokens, offering sports organisations new ways to engage with their fans. As these digital assets gain traction, understanding the factorsthat influence their acceptance becomesincreasingly critical. Thus, thisstudy usesthe Technology Acceptance Model to explore the roles of fan identity and the perceived risk in shaping fan token acceptance and aims to examine their effect on the behavioural intentions of football fans. Design/methodology/approach – Data were gathered from a sample of football fans (n 5 360) representing eight Brazilian clubs that issue official fan tokens through the Socios.com platform. Structural equation modelling was employed to test the hypothesized relationships within the proposed framework with bootstrapping techniques applied to assess the robustness of the estimates and examine the mediating effects of key variables on behavioural intentions. Findings – The results highlight the key role of TAM in predicting fan token adoption. Technological acceptance emerged as a strong predictor of both word-of-mouth communication and fan purchase intentions. Fan identity demonstrated a significant positive influence on fan token acceptance and purchase intention. Moreover, fan token acceptance was found to mediate the relationship between fan identity and behavioural intentions, indicating that fans with strong identification are more likely to adopt tokens from their sports clubs. Originality/value – This study advances theoretical understanding by incorporating fan identity, trust and perceived risk into the extended TAM framework. Our findings highlight the critical importance of trustbuilding strategies and effective risk mitigation in promoting fan adoption of technology and strengthening their behavioural intentions. The fan token industry should recognize the well-established and mediating role of technological acceptance while strengthening trust and leveraging fan identity to build deeper, value-driven connections.
- Social barriers to sports practice by people with disabilities: an integrative and critical review in sports managementPublication . Viegas, Inês; Ribeiro, Tiago; Santos, AnaThis study’s purpose is to describe and critically review the literature on social barriers (SBs) faced by people with disabilities (PwDs) in sports activities to develop a comprehensive understanding of current and further research in the field. Methodology: The Theory-Context-Characteristics Methodology (TCCM) offers a comprehensive understanding of the key theories, the contexts in which SBs occur, the characteristics of PwDs, and the research methods utilized in the field. Findings: Our analysis identified 37 SBs in 44 articles with publication year, geographical dispersion, journal type, contextual setting, methodological approaches, and variables being explored. The findings support the notion that this research topic is scarce in sport management journals, poor in other regions than North America and Europe, and has used mostly qualitative methods. Originality: This study offers a novel contribution by blending theoretical concepts with practical strategies to prevent SBs in sports. By adapting the Social Ecological Model of Inclusive Sport framework and integrating the Social Model of Disability, the study identifies specific levels of action where sport managers can intervene to reduce these barriers.
- Sex differences in health-related quality of life among individuals at high risk of dementiaPublication . Oliveira, Ana Sofia; Lopes, Sílvia; Ferreira, Lara; Cruz, Vítor Tedim; Costa, Ana RutePurpose Dementia represents an increasing challenge to health systems globally, with a notable impact on health-related quality of life (HRQoL). Nevertheless, the potential effect of sex on the relation between individuals’ characteristics and HRQoL, particularly in the early stages of this disease, remains unclear. Therefore, the present study aims to evaluate the association between sociodemographic, lifestyle and health-related factors with HRQoL among individuals at high risk of dementia, according to sex.Methods This cross-sectional study was based on baseline data from the MIND-Matosinhos randomized controlled trial, targeting Portuguese adults at high risk of dementia [n=207; 59.9% female; median age=70.0 (interquartile range: 11)]. HRQoL was measured using the EQ-5D-5L. The associations between explanatory variables and HRQoL scores (dichotomized by the median) were quantified through odds ratios (OR) and 95% confidence intervals (CI), stratified by sex. Results Overall, females reported lower HRQoL when compared with males [median (interquartile range): 0.875 (0.190) vs. 0.923 (0.129); p=0.004]. Problems in mobility (43.6% vs. 27.7%; p=0.021), pain/discomfort (71.8% vs. 44.6%; p for interaction=0.020). Conclusion Health status is associated with HRQoL, distinctively amongst males and females. These findings emphasize the need for sex-specific public health strategies to improve HRQoL in a vulnerable population of individuals at high risk of dementia.
- Smart specialisation evaluation with real project data: a general equilibrium model in Portugal’s Centro regionPublication . Szabó, Norbert; Polónyi-Andor, Krisztina; Sebestyén, Tamás; Pinto, HugoAs the first smart specialisation planning period (2014–2020) ended, monitoring and evaluation became crucial. Analysing the successes and failures of smart specialisation strategy (S3) through a good monitoring and evaluation system contributes to the evidence base on which an efficient redesign and improvement of S3 can be performed. In this paper, we apply an extended version of the geographic, macro and regional (GMR)-Europe economic impact model to provide a real-life evaluation of the implementation of S3 in Centro region using cohesion policy fund data between 2014 and 2023. Simulations reveal that policy instruments and policy mixes of priorities differ in efficiency and identify where improvements are desired.
- Waves of innovation: the role of sustainability in driving impact in the blue economy – a PLS-SEM approachPublication . Elston, Jennifer Nicole; Pinto, Hugo; Nogueira, CarlaThe Blue Economy, with its emphasis on ocean-based industries, is critical for achieving sustainable development. This study investigates the intricate relationship between sustainability, innovation, and their economic, environmental, and social impacts within Portugal’s Blue Economy. Partial Least Squares Structural Equation Modeling (PLS-SEM) was used to test the hypothesized relationships between sustainability, innovation, and triple bottom line (TBL) outcomes based on survey data from firms operating in the sector. The findings confirm that innovation acts as both a direct outcome of sustainability efforts and a mechanism for mediating its impacts on economic and environmental performance. However, no significant direct or mediating effects were observed for social outcomes, highlighting a persistent gap in this dimension that requires further research. The study contributes to both theory and practice by highlighting the strategic integration of sustainability into organizational innovation processes and its role in enhancing multidimensional performance. By identifying critical pathways and barriers, this study offers valuable guidance for policymakers and industry leaders striving to enhance the long-term sustainability of the Blue Economy.
