Globally, deep-sea shipping is one of the most indispensable form of commercial transportation services. There are considerable repercussions affecting the shipping environment caused by the rise in deep-sea vessel operations. Shifting toward eco-responsible fuel alternatives might be a plausible option for mitigating these adverse effects on the environment. However, alternative fuel selection is a complex process that depends on shipping type, multiple stakeholders’ involvement, and numerous social, environmental, and economic criteria. The baseline of such decision-making involves firm-level decision-makers who must operate ships while maintaining profitability and while complying with regulatory legislation and sustainability dimension. Therefore, firm-level decision-maker perspectives might differ significantly from other industry stakeholders (i.e., government and classification society). Particular attention must be paid to the alternative fuel selection issue from the standpoint of the ship owner and shipping company management. The current research intends to use a multi-criteria analysis as a decision-support tool for the alternative fuel selection problem in deep-sea commercial shipping on the international waterway. The proposed technique considers environmental, technological, and economic factors and ensures an exclusive focus on stakeholders at the firm-level decision-making capacity. The priority ranking of the alternatives selection criteria is based on the technique for order performance by similarity to the ideal solution (TOPSIS). Implementing this strategy considers the participation of firm-level stakeholders by analyzing each alternative’s criterion weights and performance concerning each criterion. The technique is applied to the case study of Singapore-based firms. The results demonstrated that the most important criteria with regard to an optimal alternative selection for shipping firm-level stakeholders are technological aspects, technology status, expenditures, ecosystem impact, and health-safety considerations. These results provide a foundation for decision-makers to comprehend the ship management’s priorities and interests in choosing alternative fuels. The conclusions of this analysis, the first of its kind in this field, can provide a solid foundation for strategic planning.

Disruptive technology, blockchain is propelling a technological intervention in healthcare due to its unique features and advantages. The healthcare industry is migrating to Health 4.0. Therefore, peer-to-peer (P2P) transactions in a decentralized and distributed manner make blockchain more lucrative to serve the needs of the healthcare industry of today. The revolutionary system blockchain has been discussed in the field of healthcare over the past five years. Hence, a systematic investigation of the existing body of knowledge concerning blockchain research in the healthcare domain is essential. The motivation of this study is to support further study based on the current research trend analysis through graphical visualization and analysis of the bibliographic material. Therefore, this study maps the expansion of scientific and academic research conducted concerning blockchain relevant to healthcare by utilizing a bibliometric analytic method to understand the state of the art. Bibliometric statistics have been utilized to analyze current scientific articles published in the Scopus database from 2016 to 2019. In addition, an overview of the publication trends over the first three months of 2020 has been undertaken to understand the research trend for the current year so far. The study serves the purpose of mapping research development trends in this area. The outcome discovered some beneficial insights such as the yearly trend of publications, top listed authors, institutes, countries and publishers from around the world. Moreover, this paper assists scholars to develop a theoretical framework to provide a primary source of reference in this field for further study of blockchain technology in the healthcare domain.

While the marine sector contributes significantly to the global economy, its environmental impact is a cause for apprehension due to growing concerns about ship emissions. The International Maritime Organization (IMO) has set decarbonization strategies consistent with sustainable development goals. The impending legislation aimed at reducing greenhouse gas (GHG) emissions from maritime shipping by at least half by 2050 and to zero by the end of the century. A growing body of research has focused on alternative marine fuel selection; hence, this bibliometric review is timely. We assess the global scientific research on alternative marine fuel for knowledge mapping based on the articles available on the Scopus database since 1973. A total of 749 publications associated with alternative marine fuel has been subjected to a range of bibliometric analyses to explore this research field quantitatively and qualitatively. The study utilized the R-studio bibliometrics package and VOSviewer bibliometric tools to generate the results. The field of study has a growth rate of 7.05%, having a significant contribution to knowledge from the USA, the United Kingdom, India, and China. Recent trends indicate that researchers are increasingly focused on alternative fuel oil choices. By analyzing commonly used keywords, it was possible to trace a multi-criteria decision analysis process that might be utilized to construct decision support systems for alternative maritime fuel selection. According to relevant articles, the research community has concentrated on the possibility of alternative fuels being utilized in place of traditional marine fuels to reduce emissions from the shipping sector from an environmental, technological, and economic standpoint. The current study offers an updated and comprehensive overview of research trends on alternative marine fuels. Researchers interested in data mapping work in this area can begin with this endeavor.

Seaborne trade exhibits a continual expansion with technological advancement, reportedly 10.7 billion tons in 2017, with a 3.8% growth annually. It is forecast to double in the next two decades (UNCTAD, 2018). The International Maritime Organization (IMO) is persistently heading to stricter regulatory amendments to steer shipping towards a greener and more sustainable future. Therefore, green shipping has drawn enormous interest from both academia and researchers. This paper summarizes a comprehensive bibliometric analysis aiming to understand the development of research trends in this area and suggest future research. Most of the research is focused on air pollution, practical operation or technical measures, recycling for GSP in the shipping sector. The theoretical approach to GSP and its concept is yet to be crystalline for the marine industry. According to existing research, further study is required to establish a GSP construct and propose pollution abatement technical solutions with a comprehensive evaluating tool. Besides, scholars from different territories may collaboratively suggest setting up standards and legislation of GSP for the life cycle of the ship to achieve an ever-sustainable maritime transport industry worldwide.

This study highlights several challenges along with the potential and need for blockchain technology implementation in the Malaysian healthcare industry context. The systematic review unearths potential technological, organizational, environmental, individual-level acceptance concerns and challenges associated with deploying blockchain to support electronic health records. As such, this research serves as the starting point for a chain of studies aiming at detecting, analyzing, and responding to such demands. The study is expected to guide policy and decision-making procedure of a secure and resilient health information exchange for healthcare stakeholders of developing nations such as Malaysia.
