The impact of calling on angel investing
Publication . Falcão, Rui; Moreira, Antonio; Carneiro, Maria João
Purpose – What compels business angels (BAs) to invest beyond financial returns? For many, it’s a deeper sense of calling—an alignment of purpose, values, and the desire to create lasting economic and societal impact. Traits like specialised skills, risk-taking, and a commitment to fostering innovation suggest that BAs may find profound meaning in their work. This paper aims to extend the Work as Calling Theory to the BAs’ context, analysing the impact of calling on BAs’ involvement in their work activities and on the value perceived from investing, referred to as the Angel Perceived Investment Value (APIV). Design/methodology/approach – A questionnaire survey involving 869 BAs worldwide was carried out. Structural equation modelling was used to test the proposed research model. Findings – The findings indicate a positive correlation between calling and both BAs’ involvement and APIV. Moreover, involvement was found to partially mediate the relationship between calling and APIV, contributing to perceptions of greater value. Originality/value – This study is the first to analyse in depth the impacts of calling within the context of business angels (BAs), focusing specifically on the value they derive from their investment activities. It also uniquely examines the mediating role of involvement in tasks related to the startups, the angel groups and the ecosystem. This research offers actionable suggestions to help BAs better manage the expectations arising from their sense of calling while maximizing the value they derive from their investment activities.

Exploring the intersection of environmental sustainability and anti-consumption: a review and research agenda
Publication . Inês, Ana; Moreira, Antonio
Given the adverse effects of overconsumption on environmental degradation, there is an urgent need for consumers to transition toward more sustainable consumption patterns, which involve reducing or refusing consumption. This systematic literature review (SLR) explores the intricate relationship between environmental sustainability and anti-consumption behaviors, including minimalism and voluntary simplicity. Through a consumer behavior lens, we aim to understand the intersection of various forms of anti-consumption, examining internal and external drivers, as well as barriers and outcomes. Following a mixed-method approach, this SLR of 69 studies is further complemented by six qualitative interviews with experts on this topic, identifying how consumer decisions to engage in anti-consumption are influenced by a complex interplay of personal motivations and environmental concerns. There is also an interaction between different internal and external drivers, namely religion, personal values, socioeconomic conditions, and (de)marketing strategies. Hence, consumers face some challenges when navigating the complex process of adopting anti-consumption behaviors. The outcomes range from consumer well-being to influencing corporate behavior through buycotts or boycotts. Notably, sustainability can emerge as a by-product of anti-consumption behaviors. We also propose pathways for future research, contributing to the ongoing discourse on sustainable (anti-) consumption.

Mumpreneurship: what is known, how it is known and future agenda
Publication . Amorim, Vanessa; Moreira, Antonio; Lopes, Bruno de Sousa; Rua, Orlando
Purpose – This study explores the antecedents, decisions and outcomes associated with mumpreneurship. It also reviews the primary theories, contexts and methodologies used in the existing literature on the subject. In addition, this study aims to identify potential future research directions in this field. Design/methodology/approach – A systematic literature review (SLR) was conducted following the PRISMA 2020 protocol and the ADO-TCM framework. A total of 57 articles from the Scopus and Web of Science databases were analyzed. R software was used for performance analysis and science mapping. Findings – The antecedents-decisions-outcomes (ADO) framework identified 233 factors grouped into 12 antecedent categories, 2 decisions and 4 outcomes. Antecedents include work-related issues, professional aspects, information and communication technologies, motherhood and childcare, family support, personal aspects, autonomy, independence and flexibility. In addition, financial dimensions, gender issues, societal and community impacts and the identification of entrepreneurial opportunities are integral to the antecedents. Mumpreneurs often start businesses despite challenges. Outcomes include income generation, business expansion, work–family balance and personal well-being. The theorycontext-methodology (TCM) framework highlights a reliance on empirical research, especially qualitative studies, mainly in highly developed countries. Originality/value – This review holds significant theoretical and practical value regarding mumpreneurship. The findings of this research could facilitate the development of programs that aim to foster and promote mumpreneurship through the involvement of various stakeholders, which has noteworthy practical implications for enhancing economic empowerment.

Brand evangelism: a review and research agenda
Publication . Cavadas, Ricardo; Moreira, Antonio
Brand evangelism has become an increasingly relevant concept in consumer–brand relationship research, yet existing studies remain fragmented, lacking a structured synthesis of its antecedents, mechanisms, and outcomes. This study conducts a systematic literature review (SLR) to consolidate current knowledge on brand evangelism, identify key thematic clusters, and highlight research gaps. Using the Antecedents, Decisions, and Outcomes and Theories, Contexts, and Methods frameworks, aligned with the Scientific Procedures and Rationales for Systematic Literature Reviews protocol, this review provides a comprehensive understanding of brand evangelism. A bibliometric analysis of 41 articles, supported by thematic mapping, reveals four primary research clusters: brand-centric relational evangelism, green evangelism, social media evangelism, and emotional evangelism. The findings contribute to both theory and practice by offering a structured research agenda and strategic insights for fostering brand evangelism. This study serves as a foundational resource for scholars and practitioners, guiding future research, and managerial applications in brand evangelism.

AI-powered sustainable tourism: aligning innovations with the sustainable development goals
Publication . Alves, Jéssica; Arantes, Luzia; Moreira, Antonio
This study investigates the potential of Artificial Intelligence (AI) to foster sustainable tourism practices that align with the Sustainable Development Goals (SDGs). It employs the SPAR-4-SLR protocol to conduct a systematic literature review (SLR) of 76 Q1 peer-reviewed articles identified in Web of Science and Scopus to determine the contribution of AI to environmental, social and economic sustainability. Four thematic areas emerged: (1) cocreation of value and sustainability in supply chains; (2) AI, service innovation and sustainable transitions; (3) AI, experience and governance in sustainable tourism; and (4) technology, nature and emerging frontiers. Results indicate that AI improves the sustainability process by making operations more efficient and sustainable and promotes ethical governance, inclusivity and innovation. A framework presents the interaction of AI-driven transformation, governance and ethical practices to foster a sustainable environment, contribute to SDGs 8, 9, 11, 12 and 13, and help improve SDGs 5, 7, 10, 14, 15 and 17. The study’s research agenda includes evaluating the long-term purposes of AI adoption, adoption barriers, implementation in less developed destinations and the enhancement of AI-oriented forecasting models. It provides original insights into the intersection of AI and sustainable development within tourism, providing actionable knowledge for academics, policymakers and practitioners seeking to harness AI for advancing sustainable tourism.
