Editor: Gameiro. Amandine Resumo: This paper explores how assessing and implementing the circular economy at the municipal level can serve as a catalyst for regenerative practices rooted in collective action and the responsible use of information technologies. Using the case study of Sintra, Portugal, it examines the potential of local data and digital tools to promote community engagement, resource mapping, and accountability among both public and private actors. The discussion highlights both opportunities and risks at the intersection of ecological transition, territorial equity, and participatory technologies. The circular economy is regarded not only as a strategy for resource efficiency but also as a pathway to local resilience and the sustainability of shared resources goods. 2025-01-01T00:00:00Z http://hdl.handle.net/10071/37260 Título próprio: Do CSR committees pay off? Direct and indirect links to financial and ESG performance Autoria: Lopes, A. I. Resumo: Corporate boards increasingly delegate sustainability oversight to dedicated CSR committees, yet evidence on whether these committees improve corporate performance remains mixed. This study argues that part of this inconsistency arises because prior research often emphasizes overall associations between CSR committees and performance without distinguishing between direct links and indirect benefits that operate through stakeholder-oriented CSR strategy and reporting practices. Using an unbalanced panel of 7667 firm-year observations from 1621 listed firms across 36 countries over 2010–2021, this study tests a mediation framework in which these practices transmit the relationship between CSR committee presence and both financial and nonfinancial outcomes. Results reveal a clear tension. Controlling for the mediator, CSR committee is directly associated with lower financial performance but higher ESG performance. At the same time, CSR committee presence is strongly associated with stronger stakeholder-oriented CSR strategy and reporting practices, which are positively related to both financial and ESG outcomes, generating a positive indirect effect that exceeds the direct effect in magnitude. These inferences are corroborated using instrumental-variables estimation and a simultaneous-equations approach to mitigate endogeneity concerns. Overall, the findings suggest that CSR committees “pay off” primarily through the stakeholder-oriented practices they help institutionalize, rather than through their mere existence. 2026-01-01T00:00:00Z http://hdl.handle.net/10071/37216 Título próprio: Prosociality in cyberspace: Developing emotion and behavioral regulation to decrease aggressive communication Autoria: Veiga Simão, A. M.; Ferreira, P.; Pereira, N.; Oliveira, S.; Paulino, P.; Rosa, H.; Ribeiro, R.; Coheur, L.; Carvalho, J. P.; Trancoso, I. Resumo: Different forms of verbal aggression are often present in cyberbullying, which may impair executive function skills that enable the regulation of emotions and behavior. Emotion and behavioral regulation has been associated with better social adjustment and more positive interactions between peers. This study aimed to understand if fostering emotion and behav- ioral regulation strategies could decrease aggressive communication. A quasi-experimental longitudinal design, based on a Twitter client mobile application, with pre-posttest measures was used. For the application, we explored different machine learning approaches, including computational intelligence methods. Multilevel linear modeling and frequency analyses were performed. A convenience sample of 218 adolescents (Mage = 14.67, SD = 0.84, 53% female) participated in the study. Results suggest that a Twitter client mobile application intervention based on emotion and behavioral regulation strategies may help decrease adolescents’ aggressive communication. Moreover, female and male participants who used the digital application tended to present distinct trajectories over time with regard to searching for information concerning prosocial behavior. These findings suggest that digital tools resorting to emotion and behavioral regulation strategies may be effective in reducing an aggressive communication style amongst adolescents, and consequently, promote resource seeking to engage in prosociality. These results can be significant for the design of intervention programs against cyberbullying. 2021-01-01T00:00:00Z http://hdl.handle.net/10071/37215 Título próprio: Self-efficacy, mental models and team adaptation: A first approach on football and futsal refereeing Autoria: Aragão e Pina, J.; Passos, A. M.; Maynard, M. T.; Sinval, J. Resumo: Objective: Within the football and futsal refereeing context, even though referees work within teams, there is very little research considering the implications of team dynamics. In response, this study starts to address this gap in the literature by investigating the moderating effect of mental models on the relationship between self-efficacy beliefs and perceptions of team adaptation within the exciting context of professional and national football and futsal refereeing. Design: We obtained online questionnaires from 339 active football and futsal referees within the National and Professional league at two distinct points (April and May) within the football season. Results: Self-efficacy beliefs were positively associated with perceptions of team adaptation (only for football referees). Mental models were positively associated with team adaptation. Likewise, the moderation between mental models and self-efficacy beliefs was positively associated with perceptions of team adaptation (only for futsal referees). However, such an effect was only significant at the futsal referees’ level. Conclusion: This study emphasises the importance of mental models for team adaptation and the importance of self-efficacy beliefs in predicting perceptions of team adaptation. We hope that this study represents the first step in a greater appreciation of the salience of team dynamics and their impact on football and futsal referees’ performance and that future research can build upon our work. 2021-01-01T00:00:00Z
