- Social media as a driver of physical activity: a snapshot from sport sciences studentsPublication . López-Carril, Samuel; Bae, Deukmook; Alguacil, Mario; Ribeiro, TiagoSocial media has become integral to daily life. During the COVID-19 pandemic, these digital tools enabled people to maintain physical activity at home despite restrictions, positively impacting public health. This study examines whether the trend of using social media to support physical activity has continued post-pandemic. A questionnaire was administered to 251 university sport sciences students to gauge their perceptions of social media's role in guiding and promoting physical activity. The findings indicate that participants engage with social media daily, viewing platforms such as YouTube, Instagram, and TikTok as valuable for visualizing and promoting physical activity. However, they report a lack of professional training in social media use at the university level. These results carry practical implications for health policymakers, educational institutions, faculty, students, and sport industry professionals, highlighting the importance of targeted training in social media management and the development of relevant policies to harness the potential of social media in promoting physical activity.
- Resilience in uncertainty: the impact of coping strategies on tourism entrepreneurs’ subjective well-being in sub-Saharan AfricaPublication . Ribeiro, Manuel Alector; Adam, Issahaku; Kimbu, Albert Nsom; Dayour, Frederick; Adeola, Ogechi; Tichaawa, Tembi M.This study examines how tourism entrepreneurs of Micro, Small, and Medium enterprises in sub-Saharan Africa (SAA) coped with environmental uncertainties during COVID-19 and the impact on their resilience and subjective well-being (SWB). Using a mixed-methods approach, we combined quantitative survey data from 844 participants and 23 in-depth qualitative interviews in Ghana and Nigeria. Findings reveal that environmental uncertainty triggers problem-focused coping, which significantly enhances resilience and SWB. Conversely, emotion-focused coping shows no significant relationship with uncertainty, indicating a unique response pattern in these contexts. Entrepreneurial team efficacy plays a crucial moderating role in the relationship between coping strategies, resilience, and SWB. While COVID-19 served as the primary context, the findings offer a broader perspective on how entrepreneurs navigate diverse environmental uncertainties in volatile, resource- scarce environments. These findings contribute to a contextualised understanding of entrepreneurial behaviour in SSA and provide practical implications for enhancing entrepreneur support systems in turbulent times.
- Validation and psychometric properties of the portuguese version of the Freiburg Mindfulness Inventory (FMI)Publication . Iacob, Vivien; Carmo, Cláudia; Garcês, Soraia; Chiodelli, Roberto; Walach, Harald; Neves de Jesus, SaúlThis research aimed to develop a Portuguese version of the Freiburg Mindfulness Inventory (FMI) short form and investigate its psychometric properties through two complementary studies. The first study included a sample of 337 participants. It analyzed the scale's internal consistency, reliability, and factorial validity by conducting an exploratory and confirmatory factor analysis using a randomly divided sample of the general population. The second study examined the convergent and concurrent validity, temporal stability, and sensitivity to change in the FMI among participants in an Interculturality and Mindfulness program (n = 150). The results indicated high internal consistency and reliability for the Portuguese version of FMI (omega = 0.87). The exploratory and confirmatory factor analysis reinforced the instrument's unidimensional solution. The findings supported the convergent and concurrent validity, temporal stability, and sensitivity to change. The translated version's psychometric qualities are satisfactory and can be used to assess mindfulness in the Portuguese population.
- Reasons for living and depressive symptomatology in young adults with and without suicide attempts: a moderated mediation approachPublication . Brás, Marta; Martins, Cátia; Nunes, Cristina; Neves de Jesus, Saúl; Madeira, Ana Rita; Carmo, CláudiaIntroduction Suicide is a public health problem worldwide, being the fourth leading cause of death in young adult population (15-29 years). Therefore, it is important to identify its risk and protective factors, and how they interact to develop more effective interventions. The present study aims to analyze the relation between depressive symptoms, hopelessness (risk factors) with reasons for living (protective factors) and suicidal ideation in young adults with and without previous suicide attempts.Methods A sample of 845 Portuguese young adults answered an online form which assessed suicidal ideation, hopelessness, depressive symptoms, and reasons for living. Mean comparisons, correlations, and moderated mediation analysis were computed.Results Individuals with a history of suicide attempt showed higher mean levels in risk factors, compared to individuals without suicide attempt. When no history of suicide attempt was present, ideation was positively and significantly correlated to depression and hopelessness, and negatively correlated to the reasons for living. Higher levels of depressive symptomatology predict lower levels of reasons for living. Mediation and moderation relations were assessed in a model and the history of suicide attempts showed a relevant role.Conclusions The evidence found in this study reinforce that reasons for living may play a preponderant role in suicidal ideation, that is as a negative mediator and therefore it can act as a protective factor.
- 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.
- Situational context analysis of tourists’ eWOM engagement: the moderating effects of hotel star category and review site use intensityPublication . Pérez Aranda, Javier Ramón; Pinto, Patrícia; Martins Guerreiro, Maria Manuela; Ait-Bakrim, AbderrahmanBased on interactional psychology theory, this study explored the moderating effects of hotel star category and hotel review site use intensity on two antecedents of consumer engagement with electronic word of mouth (eWOM): organizational review site competence (ORSCP) and organizational review site commitment (ORSCM). Data were collected from a cross-national sample of 443 hotels and analyzed using partial least-squares methods. The results confirm that ORSCP and ORSCM affect customers' eWOM engagement. The findings also include that the hotel star category and the use intensity of hotel review sites have a moderating effect on the ORSCP - ORSCM relationship but not on these two variables' connection with consumer eWOM engagement. This research thus ascertained that a complex relationship exists between hotels' management of social networking sites and customers' eWOM engagement, which has implications for hotel marketing specialists.
- Perceptions and behaviors concerning tourism degrowth and sustainable tourism: latent dimensions and types of touristsPublication . Pinto, Hugo; Barboza, Miriam; Nogueira, CarlaThe current economic model centered on perpetual growth is unsustainable. Without a shift away from this growth-centric approach and rampant consumerism, the environmental and social crises will persist. This article explores tourists' relationship with degrowth and sustainability. Through an empirical investigation, the study explores the relatively uncharted territory of how tourists engage with degrowth. Employing an online survey with a sample of 261 respondents obtained through convenience sampling via online distribution, the research seeks to unearth key facets of tourist behavior and categorize tourists based on their attitudes toward sustainability and degrowth. The findings indicate that degrowth remains a largely unfamiliar concept among tourists. Interestingly, those exhibiting more sustainable travel practices also display a greater alignment with degrowth principles. Conversely, younger tourists appear less inclined towards sustainable behaviors and more resistant to embracing degrowth ideologies. These findings underscore the potential of degrowth in addressing sustainability challenges within the tourism industry while emphasizing the need of including tourists and local communities in fostering a shift toward more sustainable tourism practices.
- Customer participation behavior and customer citizenship behavior in hotels: testing co-production and value-in-use as mediatorsPublication . Sadighha, Jinous; Pinto, Patrícia; Martins Guerreiro, Maria Manuela; Campos, Ana CláudiaThis study investigates customers' contribution to value co-creation by exploring the associations between customer co-creation behavior, including customer participation and customer citizenship behavior, and co-creation processes, namely, co-production and value-in-use. It combines co-creation theory with equity and social exchange theories to propose a model for customer behavior towards value co-creation. Using Partial Least Squares Structural Equation Modeling (PLS-SEM), data were collected from tourists staying at hotels in Portugal. Results indicate that customer participation behavior envisages co-production and value-in-use, while the two forms of value co-creation subsequently improve customer citizenship behavior. Moreover, co-production enhances value-in-us. Additionally, customer participation behavior is associated with customer citizenship behavior through co-production and value-in-use. This research contributes to the co-creation theory by proving co-production and value-in-use as transforming mechanisms that turn customer participation behavior into customer citizenship behavior. Applying the proposed model as a managerial tool in hotels improves co-creation processes and boosts customer citizenship behavior.
- Smart specialization, public authorities, and innovation intermediaries in developing regionsPublication . Pinto, Hugo; Laranja, Manuel; Uyarra, ElviraDespite a growing body of literature on smart specialization, the role of public authorities and innovation intermediaries, particularly in developing regions, remains understudied. This research examines one of the first attempts to apply the smart specialization framework to the development of an innovation strategy outside Europe, specifically in the Pernambuco State, Brazil. We focus on two priority areas (clothing and high-tech automotive components) identified by the state government as key targets for pilot policy experimentation and use different methods, such as social network analysis and content analysis, to interview strategic innovation actors for studying the promotion of innovation and regional development in Pernambuco. Findings highlight how regional governance, collaboration, and trust are shaped by public authorities and innovation intermediaries. The study identifies three key challenges in implementing smart specialization strategy in developing regions: i.e., achieving effective decentralization, cultivating an innovation culture, and establishing participatory governance mechanisms. The public sector actors act as crucial knowledge brokers and policy intermediaries, facilitating the linkages and partnerships necessary to overcome these challenges.
- Not in my (media) backyard: Climate justice and global media political economyPublication . Fernandes, AdalbertoJournalism's economic crisis affecting the Global South and Semi-Peripheral countries has made them more vulnerable to the mainstream media conglomerates from the Global North. The control of global agendas of information is also an opportunity to influence the political narrative about responsibilities regarding climate change. The objective of this research is to analyse how CNN Brazil and CNN Portugal depict the US climate crisis and to evaluate the influence of CNN's presence in these countries. A qualitative critical discourse analysis suggests that the US is presented as the primordial victim of climate change, being the climate change portrayed as an abstract entity that is non-politically culpable for the catastrophe. Also, the expansion of CNN has reduced Brazilian and Portuguese newsrooms to a translational work of news originally made by CNN headquarters, which is sometimes unethically disguised as original journalistic work. However, there are, even if rare, signs of resistance that read the US crisis through Brazilian and Portuguese concerns.
