- Analysing stimuli and barriers, failure and resilience in companies’ internationalization: a systematic and bibliometric reviewPublication . Martins, Rui Centeno; Farinha, Luis; Ferreira, Joao J.Purpose – This study aims to systematize and analyze the internationalization of companies in an attempt to identify the main themes explored in the literature – What does the current state of the art tell us about the stimuli and barriers, failures and resilience in the internationalization of companies is what the authors set out to answer with this research. Design/methodology/approach – This study offers a systematic review based on the bibliometric mapping techniques of 218 articles collected from the Web of Science database between 1996 and 2021. Findings – Furthermore, contributing to literature by the logic of stimuli, barriers failure in internationalization companies. The main conclusion is that, from the analysis, the authors can see that the scientific production in this field of knowledge has intensified in recent years, but the centrality and the search density undergo major changes. Originality/value – The main research contributions enable a better understanding of the involvement of failure and resilience in companies re-internationalization and suggestions for future studies in this field.
- O PAPEL DA CONTABILIDADE DE GESTÃO NO SETOR VINÍCOLAPublication . Martins, Rui CentenoA literatura que investiga a Contabilidade de Gestão, apesar de recente já vai algo extensa e fragmentada, assumindo diferentes abordagens e contribuindo em diversas áreas do setor vinícola. Portanto, importa analisar, sintetizar e reportar os assuntos que têm sido investigados neste setor, com a finalidade de evidenciar de forma clara à comunidade científica o que já foi feito e o que falta fazer sobre o fenómeno destacado. O objetivo principal deste artigo consiste na revisão sistemática da investigação em contabilidade de gestão no setor vinícola e, com esse próposito, foi utilizada a base de dados Web of Science para a recolha de 54 artigos de periódicos relevantes, datados de 1997 a 2018, com a identificação de algumas questões importantes, pelo que foram utilizados dois clusters para circunscrever a pesquisa por diferentes áreas do setor vinicola. Esta análise foi estruturada de acordo com os tópicos estudados, contextos investigados, perspetivas teóricas, métodos de investigação, e principais técnicas de análise dos dados. Os resultados obtidos proporcionam uma visão geral sobre a estrutura e evolução da investigação em Contabilidade de Gestão e indicam possíveis desenvolvimentos futuros. Esta revisão serviu de base para compreender as lacunas existentes na literatura e sugere uma futura agenda de investigação
- AI-powered ventures: How digital competencies shape entrepreneurial successPublication . Martins, Rui CentenoIn the dynamic realm of digital entrepreneurship, understanding how digital competencies shape entrepreneurial outcomes is vital, especially with the integration of artificial intelligence (AI). This study examines how digital competencies, as framed by the Theory of Planned Behavior (TPB) and Social Cognitive Theory (SCT), influence attitudes, subjective norms, digital entrepreneurial self-efficacy, intention, and behavior in the context of utilizing generative AI (BingGPT) for entrepreneurial activities. Utilizing structural equation modelling, data from 311 respondents in Portugal were analyzed. Findings reveal that digital entrepreneurial intention directly drives digital entrepreneurial behavior, with TPB Attitude and SCT Self-Efficacy as key influencers, the latter facilitating the transformation of intention into action. A novel discovery underscores that digital competencies significantly enhance digital entrepreneurial self-efficacy, boosting confidence in digital ventures. Subjective norms do not influence intention, indicating that AI adoption, such as BingGPT, is internally motivated. The study highlights the critical linkage between digital competencies and cognitive-behavioral factors in leveraging AI for entrepreneurship. It contributes to understanding how AI technologies impact attitudinal and cognitive aspects, fostering digital business ventures, and elucidates the sequential influence of digital competencies, TPB, and SCT on intention and behavior in the AI BingGPT domain.
- SustainabilityGetsSmarter:CompetitivePressureandAI LeadingtheWayPublication . Martins, Rui CentenoGrowing environmental concerns and the digital transformation of businesses have intensified the need to understand how sus- tainability and technology interact within organizational decision-making. This study examines how external market pressures, customer expectations, and competitive pressure shape internal innovation mechanisms (marketing, process, organizational) and artificial intelligence (AI) adoption, and how these factors influence decision-making toward green innovation in companies. A quantitative approach was applied using a structured questionnaire administered to 394 consumers and professionals with work experience in companies that integrate sustainability and innovation. The research model was tested through Partial Least Squares Structural Equation Modeling. Results indicate that customer expectations positively affect marketing, process, and orga- nizational innovation but do not significantly influence AI adoption, whereas competitive pressure strongly drives all innovation dimensions, including AI. All internal mechanisms positively impact green innovation decisions, with AI emerging as a strategic enabler. This study applies the stimulus– organism– response (S–O–R) framework to sustainability contexts by integrating AI as an organizational mechanism. It highlights the distinct roles of external pressures, showing that competitive pressure, not cus- tomer expectations, is the main driver for technological integration, offering actionable insights for advancing green innovation strategies.
