This research aims to understand the primary challenges encountered by entrepreneurs operating in emerging economies, where entrepreneurship plays a vital role. The study places a particular emphasis on entrepreneurs in Brazil.

The research methodology involved the analysis of data obtained from interviews, using both content analysis and Grey Relational Analysis techniques.

The analysis revealed several prominent difficulties that entrepreneurs face in these domains. These challenges encompassed issues such as grappling with intricate taxation systems and the associated tax burden, navigating government bureaucracy, securing access to essential financing and initial investments, contending with the absence of supportive government programs and addressing the dynamic nature of market conditions. The findings on the most critical barriers reveal potential pathways for entrepreneurs, policymakers and universities to act in developing the entrepreneurial ecosystem in emerging economies.

The insights garnered from this research have the potential to inform the formulation of robust public policies aimed at fostering entrepreneurship and innovation in emerging countries. Furthermore, these findings can serve as a valuable resource for planning initiatives designed to train engineers to become successful entrepreneurs.

Organizations and markets are constantly developing and changing, impacting how organizations create value and manage supply chains. This paper aims to identify the motor themes and subthemes of academic research that relate supply chain management (SCM) maturity and business models (BMs).

The Science Mapping Analysis Tool (SciMAT) was used to conduct a seven-step bibliometric analysis of 889 documents indexed in the Scopus database clustering by relatedness of works and keywords. The methodological approach included content analysis of the literature, longitudinal analysis and strategic diagram analysis.

The thematic evolution analysis revealed that three themes drive the studies on SCM maturity and BM: industry 4.0 (motor theme), environmental management (transversal theme) and product management (highly developed and isolated theme). The strategic diagrams and co-word networks allowed to graphically identify the main topics connecting SCM maturity and BM. Considering this connection, the scientific mapping emphasizes the significance and strength of the link between digital technologies, technology management and manufacturing management in Industry 4.0. In addition, the connections between the subthemes revealed that circular economy and green human resource management are important concepts to advance theory and practice on the connection between SCM maturity and BM.

This research extends the knowledge base by providing an analysis of the key themes and the links with subthemes in the literature that relate to SCM maturity and BM. Key studies are analyzed and linked with the key topics identified using the SciMAT software. Future research avenues are outlined, providing new insights to advance theory and practice.

This study aims to provide an analysis of teaching the “10 Rs” – Refuse, Rethink, Reduce, Reuse, Repair, Remodel, Remanufacture, Reuse, Recycle and Recover energy, in technological-level undergraduate courses offered in Brazil. Technological undergraduate courses are more dynamic and pragmatic than bachelor’s degrees and aim to meet market demand.

The study collected data from 39 educators who know the reality of technological-level undergraduate courses in Brazil. The data were analyzed using the fuzzy technique for order preference by similarity to ideal solution class technique.

The main findings of the research show potential for improvement in teaching all the “Rs” analyzed when considering technological-level undergraduate courses. Refuse, Restore and Recover energy are the most critical when considering how they should be taught in undergraduate technology courses in Brazil.

The paper’s originality lies in a unique empirical analysis of the circular economy – which is increasingly emerging as an intriguing approach to seeking sustainability in production chains – and the new generation of professionals in technological undergraduate courses who need to be educated and aligned with these concepts. The results can improve the curriculum, syllabus, course objectives and learning outcomes, upgrading the courses’ pedagogical projects.
