The challenges of optimizing logistics operations in all links of the supply chain have led to the development of new dynamics around the revolution 4.0 and the response of operational efficiency linked to environmental sustainability. Smart ports are born as a strategy to meet customer needs from a technological evolution that generates quality logistical and operational responses. The objective of this review is to identify and to analyze the research perspectives related to smart ports. The implemented methodology considered a scientific mapping to determine the most relevant publications in terms of authors, journals, and countries with the greatest scientific participation in the subject and a network analysis based on the implementation of the tree metaphor of the graph theory. The R-studio software and the Bibliometrix plugin were used to process the information. The review considered 204 documents from the Scopus and Web of Science databases, identifying a growing trend in the number of enhanced publications as of 2019, with China being the country with the largest number of papers. In relation to research trends, the adaptation of ports to industry 4.0, maritime ports and technological security, and green and smart ports are the perspectives on the subject of study. Finally, an agenda for future research is presented.

Youth social enterprises have become a significant component of the global economy since the late twentieth century. With the changing world and the emergence of new economies, there is a growing demand for expanding markets and reaching new customers, making it an opportune time for young entrepreneurs to utilize their unique characteristics of creativity and drive. This study aims to conduct a systematic literature review on youth social entrepreneurship through the application of bibliometric tools and methods in order to identify needs and challenges in this field. The literature was explored using the Scopus and Web of Science (WoS) databases from 2010 to 2022. The findings were analyzed using Bibliometrix and R-Studio tools, which facilitated two methodological stages: scientific mapping and network analysis. Based on the tree metaphor, the collected documents were categorized into the root, trunk, and leaves groups. The results unveiled several research clusters, including business strategies, social entrepreneurship and capitalism, and social change and innovation, were identified. In general, the above-mentioned clusters introduce fresh approaches, suggest solutions, advocate for societal change, and enrich comprehension regarding youth-driven social enterprises. Finally, this study concludes by presenting an agenda for future research in the field.

El blockchain es una tecnología emergente con reciente aplicación a la cadena de suministro. En la presente revisión se identifica y analiza las tendencias de investigación, a partir de los estudios originarios y estructurales de esta temática en Scopus, entre los años 2000 y 2022. La metodología desarrolló mapeo científico mediante bibliometría y análisis de red, utilizando la teoría de grafos con R-studio. En conclusión, se identificaron tres tendencias de la aplicación de blockchain enfocadas en transparencia, trazabilidad y seguridad de las transacciones entre los actores de la cadena de suministro; además, se plantean futuras líneas de investigación.

The operations of international trade drive global economies, with maritime transport serving as a key pillar in market connectivity and acceleration. The opportunities presented by Industry 4.0 to connect supply chain actors through integrated logistics pose a challenge that fuels the number of studies in this area, with a particular interest in the transportation stage due to its responsibilities for efficiency. This study conducts a systematic literature review by analyzing scientometric aspects and identifying research trends related to maritime transportation logistics. The PRISMA methodology, graph theory, and bibliometric indicators such as indegree, betweenness, and outdegree were employed to process the information related to maritime transportation logistics from the Scopus and Web of Science databases spanning from 2000 to 2022. The gathered information and results were processed and analyzed using R-studio and Bibliometrix tools. The documents were classified as original, structural, and research trends, with the latter focused on topics related to the environment, port competitiveness, logistics optimization, and economics. Finally, an agenda for future research in the field is presented.
